Abstract
BACKGROUND The aim of this study was to determine the psychometric properties of the Spanish-language version of the HIV-Symptom Index (HIV-SI) questionnaire in Spanish patients undergoing antiretroviral therapy. METHODS Between 2014 and 2016, an observational, multicenter, prospective cohort study was conducted in seventeen Spanish hospitals to validate HIV-SI questionnaire in terms of: construct validity (confirmatory factor analysis), internal consistency (Cronbach's alpha), convergent validity (Pearson's correlation coefficient) and Known-group validity. In addition, a sensitivity to change analysis was also performed. RESULTS A total of 232 patients were included in the study. They had a mean age of 46.17 (SD9.82) and were 75% male. The median overall score for the HIV-SI was 10 (IQR 4- 19.5) and the most common symptoms reported were feelings of nervousness or anxiety, fatigue or energy loss, feeling sad or depressed, stomach pain or bloating, and difficulty sleeping. In the current study, the Spanish HIV-SI questionnaire showed a high internal consistency (α = 0.89) and adequate construct validity (CFI and TLI > 0.90). When contrasted with the MOS-HIV questionnaire, an inverse correlation was found. It showed a good association with the mental (r=-0.61; P < 0.0001) and physical score (r=-0.60; P < 0.0001). In a multivariate analysis, the age of the patient, female condition, hepatitis C coinfection, concomitant treatment and non-adherence resulted in a higher HIV-SI score. CONCLUSIONS Our study has shown that the Spanish HIV-SI is a valid and reliable self-administered PROM for routine measurement of patient- reported symptoms among Spanish patients on antiretroviral treatment.

Abstract
Approximately one-quarter of people with HIV (PWH) in the U.S. receive coverage through the Medicare program; however, no prior real-world study has examined antiretroviral therapy (ART) gaps and adherence and associated factors in this population. This retrospective cohort analysis used 2013-2018 national Medicare fee-for-service claims data to identify all PWH initiated on a new ART regimen including protease inhibitors [PI], non-nucleoside reverse transcriptase inhibitors [NNRTIs], or integrase strand transfer inhibitors [INSTIs] between 1/1/2014 and 12/31/2017. Study outcomes included ART adherence (based on proportion of days covered [PDC]), continuous treatment gaps ranging from 1 to 6 days to ≥ 180 days, and discontinuation (continuous gap ≥ 90 days) in the 12-month follow-up period. Multivariable regressions were used to assess factors associated with ART adherence and discontinuation. The final sample included 48,627 PWH (mean age: 54.5 years, 74.4% male, 47.5% White, 89.8% disabled). Approximately 53.0% of PWH had a PDC ≥ 0.95, 30.2% had a PDC between 0.70 and < 0.95, and 16.8% had PDC < 0.70. Treatment gaps of at least ≥ 7-days (55.2%) and ≥ 30-days (26.2%) were common and 10.1% PWH discontinued treatment. Younger age, female sex, Black race, higher comorbidity score, mental health conditions, and substance use disorder were associated with higher odds of lower adherence and discontinuation (all p-values < 0.05). In conclusion, suboptimal adherence and treatment gaps in ART use were commonly observed among PWH in Medicare. Interventions and policies to mitigate barriers to adherence are urgently needed in this population to both improve their survival and increase the potential for ending the HIV epidemic in the US.

Patient-reported outcomes among virally suppressed people living with HIV after switching to Co-formulated bictegravir, emtricitabine and tenofovir alafenamide. JOURNAL OF MICROBIOLOGY, IMMUNOLOGY, AND INFECTION = WEI MIAN YU GAN RAN ZA ZHI 2023:S1684-1182(23)00034-8. [PMID: 36806364 DOI: 10.1016/j.jmii.2023.01.015] [Citation(s) in RCA: 7] [Impact Index Per Article: 3.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 10/03/2022] [Revised: 01/11/2023] [Accepted: 01/20/2023] [Indexed: 02/11/2023]
Abstract
BACKGROUND While some evidence has suggested the benefits of co-formulated bictegravir, emtricitabine and tenofovir alafenamide (B/F/TAF) in improving the quality of life of people living with HIV (PLWH), patient-reported outcome studies that focus on Asian population remain scarce. We aimed to determine the changes in HIV-related symptom burden in virally-suppressed PLWH switching to B/F/TAF in a real-world setting. METHODS PLWH on stable antiretroviral therapy (ART) for ≥6 months with plasma HIV RNA <200 copies/mL who decided to switch to B/F/TAF were eligible for the study. Participants' experience with 20 symptoms were assessed using HIV Symptom Index at baseline and weeks 24 and 48. Responses were dichotomized in two ways: 1) present vs. not present; and 2) bothersome vs. not bothersome, and compared across time points. RESULTS Six hundred and thirty participants (prior regimen, 94.4% integrase inhibitor-based) who completed week 48 visit were included in the analysis. Forty-eight weeks after switching to B/F/TAF, six symptoms were significantly less prevalent, and seven symptoms were significantly less bothersome. Improvement was more pronounced in participants whose prior regimen was elvitegravir-based versus dolutegravir-based. Logistic regression results showed that prior dolutegravir-based ART and pre-existing diabetes independently predicted improvement in diarrhea/loose bowels and muscle aches/joint pain, respectively. Despite the overall improvement, some symptoms persisted in a substantial proportion of participants. CONCLUSIONS Virally-suppressed PLWH might benefit from a regimen switch to B/F/TAF to reduce the prevalence and level of bother of HIV-related symptoms. Nevertheless, additional multidisciplinary interventions are warranted to further alleviate the symptom burden of PLWH.

First report of computational protein-ligand docking to evaluate susceptibility to HIV integrase inhibitors in HIV-infected Iranian patients. Biochem Biophys Rep 2022; 30:101254. [PMID: 35368742 PMCID: PMC8968007 DOI: 10.1016/j.bbrep.2022.101254] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/15/2022] [Revised: 03/16/2022] [Accepted: 03/17/2022] [Indexed: 12/04/2022] Open
Abstract
Background Iran has recently included integrase (INT) inhibitors (INTIs) in the first-line treatment regimen in human immunodeficiency virus (HIV)-infected patients. However, there is no bioinformatics data to elaborate the impact of resistance-associated mutations (RAMs) and naturally occurring polymorphisms (NOPs) on INTIs treatment outcome in Iranian patients. Method In this cross-sectional survey, 850 HIV-1-infected patients enrolled; of them, 78 samples had successful sequencing results for INT gene. Several analyses were performed including docking screening, genotypic resistance, secondary/tertiary structures, post-translational modification (PTM), immune epitopes, etc. Result The average docking energy (E value) of different samples with elvitegravir (EVG) and raltegravir (RAL) was more than other INTIs. Phylogenetic tree analysis and Stanford HIV Subtyping program revealed HIV-1 CRF35-AD was the predominant subtype (94.9%) in our cases; in any event, online subtyping tools confirmed A1 as the most frequent subtype. For the first time, CRF-01B and BF were identified as new subtypes in Iran. Decreased CD4 count was associated with several factors: poor or unstable adherence, naïve treatment, and drug user status. Conclusion As the first bioinformatic report on HIV-integrase from Iran, this study indicates that EVG and RAL are the optimal INTIs in first-line antiretroviral therapy (ART) in Iranian patients. Some conserved motifs and specific amino acids in INT-protein binding sites have characterized that mutation(s) in them may disrupt INT-drugs interaction and cause a significant loss in susceptibility to INTIs. Good adherence, treatment of naïve patients, and monitoring injection drug users are fundamental factors to control HIV infection in Iran effectively.

Abstract
A co-formulated, one pill once a day antiretroviral regimen (single-tablet regimen), containing efavirenz, emtricitabine, and tenofovir disoproxyl fumarate ( Atripla), revolutionized the antiretroviral therapy landscape. Single-tablet regimens provide not only dosing convenience but help optimize adherence and persistence with antiretroviral therapy to achieve durably suppressed viremia with both individual and societal benefits. Given the many excellent options available now, single-tablet regimens are the preferred choice for initiating antiretroviral therapy in almost all patients with rare exceptions for drug interactions and pregnancy, and for simplification of more complex antiretroviral therapy to a single-tablet regimen. In this special commemorative article, we celebrate this astounding advancement in antiretroviral therapy, championed by John C. Martin while CEO of Gilead Sciences, and its transformative impact on HIV care nationally and globally.

PLoS One 2022; 17:e0262533. [PMID: 35025957 PMCID: PMC8758085 DOI: 10.1371/journal.pone.0262533] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/29/2021] [Accepted: 12/28/2021] [Indexed: 11/28/2022] Open
Abstract
BACKGROUND The use of single-tablet regimens (STRs) in HIV treatment is ubiquitous. However, reintroducing the (generic) components as multi-tablet regimens (MTRs) could be an interesting cost-reducing strategy. It is essential to involve patient-reported outcome measures (PROs) to examine the effects of such an approach. Hence, this study compared PROs of people living with HIV taking an STR versus a MTR in a real world setting. MATERIALS AND METHODS This longitudinal study included 188 people living with HIV. 132 remained on a MTR and 56 switched to an STR. At baseline, months 1-3-6-12-18 and 24, participants filled in questionnaires on health-related quality of life (HRQoL), depressive symptoms, HIV symptoms, neurocognitive complaints (NCC), treatment satisfaction and adherence. Generalized linear mixed models and generalized estimation equations mixed models were built. RESULTS Clinical parameters and PROs of the two groups were comparable at baseline. Neurocognitive complaints and treatment satisfaction did differ over time among the groups. In the STR-group, the odds of having NCC increased monthly by 4,1% as compared to the MTR-group (p = 0.035). Moreover, people taking an STR were more satisfied with their treatment after 6 months: the median change score was high: 24 (IQR 7,5-29). Further, treatment satisfaction showed a contrary evolution in the groups: the estimated state score of the STR-group increased by 3,3 while it decreased by 0,2 in the MTR-group (p = 0.003). No differences over time between the groups were observed with regard to HRQoL, HIV symptoms, depressive symptoms and adherence. CONCLUSIONS Neurocognitive complaints were more frequently reported among people on an STR versus MTR. This finding contrasts with the higher treatment satisfaction in the STR-group over time. The long-term effects of both PROs should guide the decision-making on STRs vs. (generic) MTRs.

Abstract
Background Antiretroviral therapy (ART) has been shown to significantly reduce the likelihood of transmission to other people as well as promoting the health of people living with Human immunodeficiency virus/acquired immunodeficiency syndrome (HIV/AIDS) (PLH). The purpose of this study was to assess the HIV care continuum of PLH in Korea using the national health insurance system (NHIS) database. Materials and Methods From 2006 to 2015, ART prescription/laboratory test claim data and enlisted accompanying comorbidities were extracted from the NHIS database. Utilizing these data, proportion of PLH on ART among those who registered to Korea Disease Control and Prevention Agency (KDCA), HIV viral load testing, prescription trends of ART, medication possession ratio (MPR) of ART, and accompanying comorbidities were reviewed. Factors related with MPR <90% was also investigated among demographic factors, ART prescription, and accompanying comorbidities. Results During the observation period, the number of people receiving ART prescription increased from 2,076 in 2006 to 9,201 in 2015. Considering the number of PLHs reported by the KDCA, the proportion of PLHs who received ART prescription increased from 55.4% to 87.6% during the study period. The median value of ART MPR increased from 76.4% to 94.2% and the proportion of patients with MPR >90% increased from 54.3% to 78.2%. The most commonly accompanying comorbidities were dyslipidemia (55.7%), osteoporosis (16.3%), hypertension (15.7%) and diabetes (13.7%), respectively. The proportion of PLH with two or more comorbid conditions increased from 22.0% to 31.6%. Regarding the factors associated with suboptimal compliance, age less than 50 years old, under support of National Medical Aid, alcoholic liver disease, mental and behavioral disorders due to use of alcohol, and ART regimen of protease inhibitor and non-single table regimen integrase strand transfer inhibitor were related with MPR <90%. Conclusion The proportion of PLHs who received ART prescription and median MPR of ART increased during the study period. However, proportion of patients with MPR >90% was 78.2% in 2015 and there are still much room for improvement in the aspect of compliance.

Abstract
BACKGROUND Antiretroviral dual regimens including lamivudine and one boosted PI or dolutegravir are warranted in order to optimize combination ART (cART), prevent long-term toxicity and reduce the cost of treatments. OBJECTIVES We hypothesized that a maintenance dual regimen of lamivudine plus raltegravir would be effective and as well tolerated as the dual maintenance combination of lamivudine plus dolutegravir. METHODS We performed an observational, retrospective study of HIV-infected patients on suppressive ART who switched to a dual regimen containing lamivudine 300 mg once daily plus raltegravir 1200 mg once daily or dolutegravir 50 mg once daily. RESULTS In total, 109 patients (79 men; mean age 46.4 years; mean CD4+ T lymphocyte count 605 cells/mm3) were enrolled. Overall, 50 subjects switched to lamivudine plus raltegravir (Group A) and 59 to lamivudine plus dolutegravir (Group B). After 12 months, 45 patients (90%) in Group A and 52 (88.1%) in Group B had HIV RNA <20 copies/mL. No patients had severe adverse effects in either group, and the percentages of patients with mild adverse effects were comparable, except for a higher incidence of headache and sleeping disturbances in Group B than in Group A (30.5% versus 14%, P < 0.001). A comparable and non-significant weight increase was reported in both groups (+1.91 kg in Group A and +2.28 kg in Group B). CONCLUSIONS In our study, dual therapies containing lamivudine plus raltegravir or dolutegravir in virologically suppressed patients showed high and comparable efficacy, as well as good tolerability.

Abstract
We aimed to assess patterns of patient-reported outcomes (PRO) instruments' utilization in HIV clinical trials in relation to antiretroviral therapy (ART). PubMed/MEDLINE, Scopus, and EMBASE were searched using the terms "Patient-Reported Outcomes" and "HIV/AIDS" or "Antiretroviral Treatment" or "ART" or "Antiretroviral Therapy" from 1 January 1990 until 1 December 2019. In total, 173 studies were identified and 26 were directly related to ART. Study population included treatment-naïve patients (n = 4), treatment-experienced (n = 20), or both (n = 2). Instruments were implemented to assess general experience with ART (n = 3), single-tablet regimens (STR) (n = 2), monotherapy (n = 4), regimen switch (n = 9), or regimen comparison (n = 8). The most commonly used instruments were Medical Outcomes Study-HIV Health Survey (MOS-HIV, n = 8), HIV Symptom Index (HIV-SI, n = 7) and unstructured self-reports (n = 5) followed by others. MOS-HIV was used mainly in comparative (n = 4) and monotherapy (n = 3) trials, HIV-SI in switch (n = 4) and STR (n = 2) trials, and self-reports in comparative trials (n = 3). Even though, the implementation of PRO tools is increasing with time, reporting of PRO in HIV clinical trials remains limited.

Abstract
Background To describe our experience with the use of Elvitegravir/Cobicistat/Emtricitabine/Tenofovir Alafenamide (EVG/COBI/FTC/TAF) in the treatment of HIV-infected patients in Qatar including both naïve and treatment experienced. We also report the reasons for switching to EVG/COBI/FTC/TAF in treatment-experienced patients, response to treatment, and tolerability. Method Review of the medical records of the first 100 HIV-infected patients treated with EVG/COBI/FTC/TAF. Results Among the 100 HIV-infected patients who were treated with EVG/COBI/FTC/TAF, 64 were Qatari and the rest were from other nationalities. 80 patients were males and 20 were females. 29 were treatment naïve, and 71 were treatment experienced. Among treatment-experienced patients, the most common reasons for switch to EVG/COBI/FTC/TAF were safety concerns, followed by regimen simplification and adverse drug reaction of the previous regimen (40%, 14%, and 13%, respectively). Treatment response to EVG/COBI/FTC/TAF leading to undetectable viral load in naïve patients was 69%, and in treatment-experienced patients, it was 83% with an overall response among all patients of 79%. Excluding those who left the country and whose data were not available, the response rate will be 86%. Tolerability was excellent with mild side effects and no discontinuation due to side effects. Conclusion Experience with the use of EVG/COBI/FTC/TAF in 100 patients with HIV infection in Qatar was favourable both in treatment naïve patients and in those who were treatment experienced with an excellent tolerability.

Desimplification to multi-tablet antiretroviral regimens in human immunodeficiency virus-type 1 infected adults: A cohort study. World J Clin Cases 2019; 7:1814-1824. [PMID: 31417927 PMCID: PMC6692266 DOI: 10.12998/wjcc.v7.i14.1814] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/11/2019] [Revised: 05/02/2019] [Accepted: 05/23/2019] [Indexed: 02/05/2023] Open
Abstract
BACKGROUND Highly active antiretroviral therapy (HAART) is provided free of charge to all human immunodeficiency virus (HIV) positive residents in Italy. As fixed dose coformulations (FDCs) are often more expensive in comparison to the same drugs administered separately in a multi-tablet regimen (MTR), we considered a cost-effective strategy involving patients in the switch from their FDCs to corresponding MTRs including generic antiretrovirals.
AIM To verify if this would affect the virological and immunological response in comparison to maintaining the FDC regimens.
METHODS From January 2012 to December 2013, we assessed the eligibility of all the HIV-1 positive adults on stable HAART being treated at our hospital-based outpatient clinic in Treviso, Italy. Participants who accepted to switch from their FDC regimen to the corresponding MTR joined the MTR group, while those who maintained a FDC regimen joined the FDC group. Clinical data, including changes in HAART regimens, respective reasons why and adverse effects, were recorded at baseline and at follow-up visits occurring at weeks 24, 48 and 96. All participants were assessed for virological and immunological responses at baseline and at weeks 24, 48 and 96.
RESULTS Two hundred and forty-three eligible HIV-1 adults on HAART were enrolled: 163 (67%) accepted to switch to a MTR, joining the MTR group, while 80 (33%) maintained their FDCs, joining the FDC group. In a parallel analysis, there were no significant differences in linear trend of distribution of HIV-RNA levels between the two groups and there were no significant odds in favour of a higher level of HIV-RNA in either group at any follow-up and on the overall three strata analysis. In a before-after analysis, both FDC and MTR groups presented no significant differences in distribution of HIV-RNA levels at either weeks 48 vs 24 and weeks 96 vs 24 cross tabulations. A steady increase of mean CD4 count was observed in the MTR group only, while in the FDC group we observed a slight decrease (-23 cells per mmc) between weeks 24 and 48.
CONCLUSION Involving patients in the switch from their FDC regimens to the corresponding MTRs for economic reasons did not affect the effectiveness of antiretroviral therapy in terms of virological response and immunological recovery

Abstract
BACKGROUND Antiretroviral therapy (ART), when taken consistently, reduces morbidity and mortality associated with human immunodeficiency virus and viral transmission. Suboptimal treatment adherence is associated with regimen complexity and high tablet burden. Single-tablet regimens (STRs) provide a complete treatment regimen in a single tablet. This study examined the relationship between STRs (vs multiple-tablet regimens [MTRs]), treatment adherence, and viral suppression. METHODS A systematic review was conducted to identify studies investigating at least one of the following: (1) STR/MTR use and adherence; (2) levels of adherence and viral suppression; and (3) STR/MTR use and viral suppression. Meta-analysis was performed to assess the relationship between STR vs MTR use and adherence in observational settings at ≥95% and ≥90% adherence thresholds. RESULTS In total, 29 studies were identified across the three objectives; two studies were relevant for all objectives. STRs were associated with higher treatment adherence than MTRs in 10/11 observational studies: a 63% greater likelihood of achieving ≥95% adherence (95% CI=1.52-1.74; P<0.001) and a 43% increase in the likelihood of achieving ≥90% adherence (95% CI=1.21-1.69; P<0.001). Higher adherence rates were associated with higher levels of viral suppression in 13/18 studies. Results were mixed in five studies investigating the association between STR or MTR use and viral suppression. CONCLUSION Although the direct effect of STRs vs MTRs on viral suppression remains unclear, this study provided a quantitative estimate of the relationship between STRs and ART adherence, demonstrating that STRs are associated with significantly higher ART adherence levels at 95% and 90% thresholds. Findings from the systematic review showed that improved adherence results in an increased likelihood of achieving viral suppression in observational settings. Future research should utilize similar measures for adherence and evaluate viral suppression to improve assessment of the relationship between pill burden, adherence, and viral suppression.

Abstract
Background Single-tablet regimens are preferred prescription choices for HIV treatment, but there are limited outcomes data comparing single-tablet regimens to multiple-tablet regimens. Methods We retrospectively assessed treatment-naïve patients at a single urban HIV clinic in the United States for viral load suppression at 6 and 12 months after initiating either single-tablet or multiple-tablet regimens. Multivariate regression was performed to obtain relative risks and adjust for potential confounders. Results Of 218 patients, 47% were on single-tablet regimens and 53% on multiple-tablet regimens; 77% of single-tablet regimen patients had undetectable viral load at 6 months compared to 61% of multiple-tablet regimen patients (p = 0.012). At 12 months, 82% on single-tablet regimens and 66% on multiple-tablet regimens (p = 0.019) had undetectable viral load. Relative risk of any detectable viral load was 1.6 (95% confidence interval: 1.1-2.5) for patients on multiple-tablet regimens compared to single-tablet regimens at 6 months, and 2.2 (95% confidence interval: 1.2-4.0) at 12 months. Conclusion Single-tablet regimens may provide better virologic control than multiple-tablet regimens in urban HIV-infected persons.

Abstract
OBJECTIVES To compare outcomes with single tablet regimens (STR) versus multi-tablet regimens (MTR) for human immunodeficiency virus (HIV) treatment using published data. DESIGN Systematic review and random-effects meta-analysis of literature on approved and investigational HIV regimens. METHODS The research followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Single or un-blinded studies reporting a direct comparison between STR and MTR were eligible for the meta-analysis. Double-blinded studies were excluded due to lack of difference in pill burden between cohorts. The key outcomes of interest included: adherence rates/proportion meeting target, efficacy, safety/tolerability, non-clinical and economic outcomes. RESULTS After screening 63 full-text articles and posters, 14 studies were eligible for the meta-analysis. The analysis showed that patients taking STR had improved outcomes over those taking MTR. Patients were significantly more adherent regardless of daily dosing frequency (odds ratio [OR]: 1.96, p < 0.001) and were more likely to achieve virological suppression (relative risk [RR]: 1.05, p = 0.002). There was a trend toward a lower discontinuation risk in the STR cohort, together with reported higher therapy satisfaction, better symptom control, improved health status, reduced healthcare resource utilization and demonstrated cost-effectiveness compared to MTR. There were no differences in CD4 cell count increase (at 48 weeks) or safety outcomes. CONCLUSIONS The findings of this study confirm previously reported preliminary findings of the advantages of STR over MTR for HIV treatment in adherence, therapy continuation, viral suppression, tolerability, quality of life improvement, cost-effectiveness and healthcare resource utilization.

Abstract
Adherence to antiretroviral (ARV) is crucial to achieve viral load suppression in HIV-infected patients. This study aimed to compare adherence to generic multi-tablet regimens (MTR) vs. brand MTR likely to incorporate ARV drugs without breaking fixed-dose combinations (FDC) and brand single-tablet regimens (STR) likely to incorporate generics by breaking the FDC. Patients aged of 18 years or over exposed to one of the generic or the brand of lamivudine (3TC), zidovudine/lamivudine (AZT/TC), nevirapine (NVP), or efavirenz (EFV), or the brand STR of efavirenz/emtricitabine/tenofovir (EFV/FTC/TDF). Adherence was measured by medication possession ratio (MPR) using both defined daily dose (DDD) and daily number of tablet recommended for adults (DNT). Adherence to generic MTR vs. brand MTR and brand STR was compared using Kruskal-Wallis. The overall median adherence was 0.97 (IQR 0.13) by DNT method and 0.97 (0.14) by DDD method. Adherence in patients exposed to generic MTR (n = 165) vs. brand MTR (n = 481) and brand STR (n = 470) was comparable by DNT and DDD methods. In conclusion, adherence to generic MTR was high and comparable with adherence to brand MTR and to STR. Utilization of DDD instead DNT to measure the MPR led to small but nonsignificant difference that has no clinical impact.

Abstract
HIV treatment depends on high-levels of antiretroviral therapy (ART) adherence, which is severely impeded by poverty. Men and women living with HIV infection (N = 92) completed computerized interviews of demographic and health characteristics, poverty markers, stressful life events, and life chaos, as well as unannounced pill counts to determine prospective medication adherence and medical record chart abstractions for HIV viral load. Poverty markers were associated with both stressors and chaos, and the direct effects of all three factors predicted ART non-adherence. The multiple mediation model showed that accounting for stressors and chaos resulted in a non-significant association between poverty markers and ART adherence. The indirect effect of poverty markers on adherence through life chaos was significant, whereas the indirect effect of poverty markers on adherence through stressors was not significant. Factors that render HIV-related stress and create chaos offer intervention targets that are more amenable to change than poverty itself.

Abstract
BACKGROUND Barriers to HIV medication adherence may differ by levels of dosing schedules. PURPOSE The current study examined adherence barriers associated with medication regimen complexity and simplification. METHODS A total of 755 people living with HIV currently taking anti-retroviral therapy were recruited from community services in Atlanta, Georgia. Participants completed audio-computer-assisted self-interviews that assessed demographic and behavioral characteristics, provided their HIV viral load obtained from their health care provider, and completed unannounced phone-based pill counts to monitor medication adherence over 1 month. RESULTS Participants taking a single-tablet regimen (STR) were more likely to be adherent than those taking multi-tablets in a single-dose regimen (single-dose MTR) and those taking multi-tablets in a multi-dose regimen (multi-dose MTR), with no difference between the latter two. Regarding barriers to adherence, individuals taking STR were least likely to report scheduling issues and confusion as reasons for missing doses, but they were equally likely to report multiple lifestyle and logistical barriers to adherence. CONCLUSIONS Adherence interventions may need tailoring to address barriers that are specific to dosing regimens.

Abstract
Minimal information is available regarding antiretroviral prescribing patterns and outcomes for HIV patients in correctional systems. This study analyzes single- (STR) and multiple- (MTR) tablet regimen effectiveness in patients receiving HIV telemedicine care through the Illinois Department of Corrections (IDOC). This study involves a retrospective review of HIV-positive adult patients in IDOC on either an STR (efavirenz, rilpivirine, elvitegravir based) or an MTR (emtricitabine/tenofovir with atazanavir/ritonavir, darunavir/ritonavir, or raltegravir). No significant differences in virologic suppression were seen between groups at baseline, weeks 24, 48, 96, and last clinic visit. Similar proportions of patient-reported adverse effects, self-reported adherence, and discontinuation rates were found in both groups. With similar rates of viral suppression, tolerability, adherence, and discontinuation, administering MTR in the incarcerated population is a viable alternative to STR.

Abstract
BACKGROUND The ritonavir-boosted protease inhibitor (PI/r)-based dual regimens are warranted in order to optimize the combination antiretroviral therapy (cART), prevent the long-term toxicity and reduce the cost of treatments. METHODS We performed an observational, retrospective study of HIV-infected patients on suppressive antiretroviral therapy who switched to a dual regimen containing lamivudine (3TC) plus darunavir/ritonavir (DRV/r) 800/100 mg qd or atazanavir/ritonavir (ATV/r) 300/100 mg qd. RESULTS As a whole, 122 well-treated patients (mean age, 45.2 years; mean CD4 T + lymphocyte count, 589 cells/mm3; mean duration of current cART, 3.1 years) were enrolled. Current antiretroviral regimen included tenofovir/emtricitabine in 91 subjects, abacavir/lamivudine in 25, lopinavir/r in 41, DRV/r in 38 and ATV/r in 33. Baseline mean estimated glomerular filtration rate (eGFR) was 94.2 mL/min/1.73 m2, and proteinuria was detected in 46 subjects (38%). Overall 70 subjects switched to 3TC + DRV/r (group A) and 52 to 3TC + ATV/r (group B). After 12 months, 65 patients (92.8%) in group A and 46 (88.4%) in group B showed HIV RNA <20 copies/mL. A significant and comparable increase in eGFR was observed in group A and B (+3.8 and +3.1 mL/min/1.73 m2, respectively), such as a significant decrease in prevalence of proteinuria. A significantly greater increase in total bilirubin concentration was reported in group B than in group A. CONCLUSION In our study, simplification to a dual therapy containing 3TC + DRV/r or ATV/r in virologically suppressed patients was effective and showed a good tolerability profile.

Abstract
The study was designed to investigate the median duration of second antiretroviral regimens and factors associated with early discontinuation in HIV patients who switched with an undetectable viral load. We conducted a retrospective analysis of the Italian Cohort Naive Antiretrovirals Foundation Study (ICONA), which collects data throughout the country. Patients who started first antiretroviral therapy (ART) after January 1, 2008 in any center involved in this cohort and then switched to a second regimen were included in the study. Second ART failure was described as two HIV-RNA >200 copies/mL or the discontinuation of any drug. Statistical analysis was performed utilizing Kaplan-Meier curves and Cox regression model. The study population included 835 patients and the median duration of first ART regimens was 16 months with HIV-RNA undetectable for 13 months. The main causes of switch to second ART regimens were toxicity (42.5%) and simplification (37.5%). The switch mostly involved the third drug (63.5%) and almost one third of the population received a single-tablet regimen (STR) as second treatment (30.6%). The median duration of second ART regimens was 9.2 months and the probabilities of treatment discontinuation at 12, 24, and 36 months were 21%, 35%, and 48.2%, respectively. STR formulations had a protective effect against second ART discontinuation. Almost half of our population needed a third regimen within 3 years, but STR could improve second ART durability.

Int J Antimicrob Agents 2017; 50:365-370. [PMID: 28689877 DOI: 10.1016/j.ijantimicag.2017.03.026] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.1] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/04/2016] [Revised: 03/13/2017] [Accepted: 03/22/2017] [Indexed: 01/19/2023]
Abstract
BACKGROUND The use of tenofovir disoproxil fumarate (TDF) has simplified the antiretroviral regimen for HIV-infected patients and improved their compliance with treatment, but it has been associated with decreased bone mineral density (BMD) in adult patients, and data in pediatric patients are debated. The aim of the current study was to assess the long-term effect of TDF on BMD in young patients. METHODS BMD was measured at the lumbar spine and in the whole skeleton in 26 HIV-infected youths (13 female and 13 male, aged 5 to 17 years at baseline). BMD was measured yearly for 10 years as part of standard care. BMD changes were compared with those calculated from 202 healthy subjects aged 3 to 24 years. FINDINGS All patients had good control of the infection during the 10-year study. BMD measurements changed significantly (P <0 ⋅ 0001) in HIV-infected youths. The mean annual BMD increment at the lumbar spine was 0 ⋅ 046 (0 ⋅ 006) g/cm2 and 0 ⋅ 042 (0 ⋅ 006) g/cm2 in males and females, respectively. The differences between the slopes of patients and healthy controls were not significant. The annual BMD increment of the whole skeleton was 0 ⋅ 030 (0 ⋅ 005) g/cm2 in males and 0 ⋅ 019 (0 ⋅ 004) g/cm2 in females. The slopes of BMD changes of patients and healthy controls did not differ significantly. INTERPRETATION These data indicate that treatment with a TDF-containing antiretroviral regimen does not impair BMD in young patients with HIV-infection. Larger studies are needed to confirm these results.

Abstract
OBJECTIVE To assess the efficacy and safety of a new single-tablet regimen (STR) of tenofovir disoproxil fumarate (TDF) 300mg, lamivudine (3TC) 300mg, and efavirenz (EFV) 600mg in HIV-infected Thai patients. METHODS This was a prospective study performed for 144 weeks among 51 treatment-naïve patients and 49 experienced patients on separate tablets of TDF, 3TC, and EFV with HIV RNA<50 copies/ml. CD4, HIV RNA, liver and renal function, and lipid profiles were assessed at baseline, weeks 12, 24, and 48, and then every 24 weeks. RESULTS The median baseline CD4 cell count was 512 cells/μl for treatment-experienced patients and 230 cells/μl for treatment-naïve patients. Median baseline log10 HIV-1 RNA for treatment-naïve subjects was 4.9 copies/ml. From the intention-to-treat (ITT) analysis, the proportion of subjects with HIV RNA <50 copies/ml at week 48, 96, and 144 was 95%, 94%, and 94%, respectively, for antiretroviral-experienced patients and 88%, 90%, and 80%, respectively, for antiretroviral-naïve patients. One virological failure at week 12 had primary drug resistance of K70R, T69D, V75L. Three serious adverse events occurred (tension headache, infective endocarditis, and cervical dysplasia) and another three discontinued the study drug due to EFV intolerance. CONCLUSIONS This generic STR TDF/3TC/EFV is effective and well-tolerated. These findings lend support to the use of this generic STR as first-line antiretroviral therapy in resource-limited settings.

Abstract
We determined risk of virologic failure (VF) in individuals initiating tenofovir/emtricitabine/efavirenz as single versus multiple tablet regimens (MTR). We found no significant difference in the risk of VF, though did observe a trend toward more VF and M184 V mutations among persons initiating MTR. Temporal trends in care may have confounded results.

Abstract
Introduction More than 27,000 Australians currently live with HIV. Most of these people have access to quality clinical care and antiretroviral treatment (ART) and can expect good general health. However, HIV-related stigma is a problem and many people living with HIV experience poorer than average mental health. Issues of aging are also of increasing concern. This paper describes the methods and sample for the HIV Futures 8 study, a national survey of people living with HIV in Australia that aimed to identify factors that support health and well-being among this population. HIV Futures 8 forms part of a series of cross-sectional surveys (The “HIV Futures” studies) that have been repeated periodically since 1997. In the most recent survey, participants were able to opt into a prospective longitudinal study. Materials and equipment HIV Futures 8 was open to people aged over 17 who were living with HIV. Data were collected in 2015/2016 using a self-complete survey that contained approximately 250 items related to physical and mental health, use of ART, HIV exposure and testing, financial security, social connectedness, relationships, life satisfaction, resilience, stigma, use of health and support services, and health literacy. To enable comparison of cross-sectional data over time, questionnaire items were consistent with those used in previous HIV Futures surveys. In HIV Futures 8, participants were invited to volunteer coded information that will allow longitudinal follow-up when participants complete subsequent HIV Futures surveys. The survey was advertised through the networks of HIV organizations, on social media and through HIV clinics and services. HIV Futures 8 was completed by 895 participants. This represents approximately 3.8% of the total number of people living with diagnosed HIV in Australia in 2014. Expected impact of the study on public health Findings from HIV Futures 8 will contribute important insights into the complexity of factors that support physical and mental well-being among people living with HIV. The findings will also assist HIV services to align with broader public health goals related to increasing ART use and improving quality of life among people living with HIV.

Abstract
Background This analysis aimed at evaluating the impact of a therapeutic strategy of treatment simplification of atazanavir (ATV)+ ritonavir (r) + lamivudine (3TC) in virologically suppressed patients receiving ATV+r+2 nucleoside reverse transcriptase inhibitors (NRTIs) on the budget of the Italian National Health Service (NHS). Methods A budget impact model with a 5-year time horizon was developed based on the clinical data of Atlas-M trial at 48 weeks (in terms of percentage of patients experiencing virologic failure and adverse events), from the Italian NHS perspective. A scenario in which the simplification strategy was not considered was compared with three scenarios in which, among a target population of 1,892 patients, different simplification strategies were taken into consideration in terms of percentage of patients simplified on a yearly basis among those eligible for simplification. The costs considered were direct medical costs related to antiretroviral drugs, adverse events management, and monitoring activities. Results The percentage of patients of the target population receiving ATV+r+3TC varies among the scenarios and is between 18.7% and 46.9% in year 1, increasing up to 56.3% and 84.4% in year 5. The antiretroviral treatment simplification strategy considered would lead to lower costs for the Italian NHS in a 5-year time horizon between −28.7 million € and −16.0 million €, with a reduction of costs between −22.1% (−3.6 million €) and −8.8% (−1.4 million €) in year 1 and up to −39.9% (−6.9 million €) and −26.6% (−4.6 million €) in year 5. Conclusion The therapy simplification for patients receiving ATV+r+2 NRTIs to ATV+r+3TC at a national level would lead to a reduction of direct medical costs over a 5-year period for the Italian NHS.

Abstract
OBJECTIVES The objectives were 1) to elicit relative preferences for attributes of antiretroviral therapies (ART) in people living with HIV (PLWH) and 2) to explore satisfaction and adherence with current ART. PATIENTS AND METHODS We conducted a multicenter cross-sectional study, consecutively enrolling PLWH receiving an ART. The quantitative part estimated the strength of preference for different attributes using an online discrete choice experiment (DCE). DCE data were analyzed using a mixed logit regression model. Qualitative data were collected through individual interviews. A preliminary coding framework was developed which was then further refined and applied during thematic analysis of factors influencing satisfaction and adherence. RESULTS A total of 101 PLWH took part in the quantitative part and 31 in the qualitative part. Over 90% had an undetectable viral load. Quantitative data revealed a strong preference for a treatment with limited drug-drug interactions, diarrhea and long-term health problems (P<0.0001), and that did not need to be taken on an empty stomach (P<0.0001). Patients also preferred to avoid problems associated with treatment failure (P<0.0001) or one that left them with a higher viral load after the first weeks of treatment (P=0.044). Differences in CD4 cell count, and pills that must be taken with food were not significant drivers of treatment choice. The strength of these attributes was reflected in the qualitative data, highlighting the importance patients place on treatment efficacy, and also suggesting that some of these attributes may impact adherence. Many factors influencing adherence and satisfaction with treatment were identified, including pill size, worry about sexual transmission and impact on social life. CONCLUSION Most of the attributes included in this survey were important to participants when choosing an ART, in particular those related to quality of life, and these should be taken into account in order to optimize adherence and satisfaction.

Abstract
Objective: Evaluate the impact of fixed-dose combination (FDC) containing emtricitabine (FTC), tenofovir (TDF), and efavirenz (EFV) versus a free-dose combination (FRC) of the same three drugs on clinical outcomes, adherence and quality of life in Malaysian outpatients with HIV. Methods: HIV patients (n=120) on highly active antiretroviral therapy (HAART) in the infectious disease clinic of Hospital Sungai Buloh were randomized to either FDC (n=60) or FRC (n=60). Morisky scores, health-related quality of life scores and clinical outcomes such as CD4 count and viral load were assessed in both groups at baseline and six months. Result: Patients on FDC (108 SD=1.1) had a significantly higher CD4 count increase compared to the FRC group (746.1 SD=36.3 vs 799.8 SD=33.8) (p <0.001). The viral load profile was unchanged and remained undetectable in both groups. The quality of life EQ-5D scores showed a positive correlation with CD4 counts in the FDC group (ρ=0.301, p=0.019) at six months. On the other hand, quality of life EQ-VAS scores was significantly associated with medication adherence in the FDC group at six months (ρ=0.749, p=0.05). However, no significant changes or associations were observed in the FRC group. Conclusion: Management of HAART using an FDC demonstrated a positive clinical outcome, adherence and quality of life within six months in local HIV patients.

Abstract
BACKGROUND Tenofovir disoproxil fumarate (TDF) is a component of many combinations of antiretroviral treatment (ART) regimens. Although potent and generally well tolerated, TDF may cause renal and bone toxicity. The magnitude of off-target side effects is proposed to be related to tenofovir plasma concentrations, which are affected by food and drug-drug interactions with concomitant antiretrovirals. OBJECTIVE To perform a systematic literature review and qualitatively report on renal and bone safety outcomes associated with efavirenz (EFV), emtricitabine (FTC), and TDF (EFV+FTC+TDF) ART. METHODS Embase and PubMed databases were searched for randomized clinical trials and observational cohort studies reporting on HIV treatment with EFV+FTC+TDF. Relevant articles were hand-searched for renal (Grade 3-4 serum creatinine/estimated glomerular filtration rate elevations, renal adverse events [AEs], discontinuation due to renal AEs, and urinary biomarkers) and bone outcomes (bone mineral density [BMD] reductions, bone turnover markers, and fracture), and results compiled qualitatively. RESULTS Of 337 retrieved articles, 29 reporting renal and 11 reporting bone outcomes met the review criteria. EFV+FTC+TDF was associated with a low frequency of renal AEs and treatment discontinuations due to renal AEs. Renal AEs were more frequent when TDF was taken with protease inhibitor (PI)- or cobicistat-containing ART. EFV+FTC+TDF was associated with reduced BMD and increased bone turnover markers, but BMD reductions were less than with PI-containing ART. No treatment-related bone fractures were identified. CONCLUSIONS EFV+FTC+TDF appeared to have a more favorable renal safety profile than TDF administered with a PI or cobicistat. BMD decreased with EFV+FTC+TDF, but no treatment-related fractures were identified.

Abstract
Background Antiretroviral therapy (ART) regimens containing efavirenz (EFV) are recommended as part of universal ART for pregnant and breastfeeding women. EFV may have appreciable side effects (SE), and ART adherence in pregnancy is a major concern, but little is known about ART SE and associations with adherence in pregnancy. Methods We investigated the distribution of patient-reported SE (based on Division of AIDS categories) and the association of SE with missed ART doses in a cohort of 517 women starting EFV+3TC/FTC+TDF during pregnancy. In analysis, SE were considered in terms of their overall frequency, by systems category, and by latent classes. Results Overall 97% of women reported experiencing at least one SE after ART initiation, with 48% experiencing more than five SE. Gastrointestinal, central nervous system, systemic and skin SE were reported by 81%, 85%, 79% and 31% of women, respectively, with considerable overlap across groups. At least one missed dose was reported by 32% of women. In multivariable models, ART non-adherence was associated with systemic SE compared to other systems categories, and measures of the overall burden of SE experienced were most strongly associated with missed ART doses. Conclusion These data demonstrate very high levels of SE in pregnant women initiating EFV-based ART and a strong association between SE burden and ART adherence. ART regimens with reduced SE profiles may enhance adherence, and as countries expand universal ART for all adult patients, counseling must include preparation for ART SE.

Abstract
HIV-1-infected patients with suppressed plasma viral loads often require changes to their antiretroviral (ARV) therapy to manage drug toxicity and intolerance, to improve adherence, and to avoid drug interactions. In patients who have never experienced virologic failure while receiving ARV therapy and who have no evidence of drug resistance, switching to any of the acceptable US Department of Health and Human Services first-line therapies is expected to maintain virologic suppression. However, in virologically suppressed patients with a history of virologic failure or drug resistance, it can be more challenging to change therapy while still maintaining virologic suppression. In these patients, it may be difficult to know whether the discontinuation of one of the ARVs in a suppressive regimen constitutes the removal of a key regimen component that will not be adequately supplanted by one or more substituted ARVs. In this article, we review many of the clinical scenarios requiring ARV therapy modification in patients with stable virologic suppression and outline the strategies for modifying therapy while maintaining long-term virologic suppression.

Abstract
INTRODUCTION Since the last revision of both European and American guidelines (EACS and DHHS), new data from clinical trials and cohort studies, as well as experience in clinical practice, have prompted significant changes to the list of recommended/preferred options for the treatment of HIV infected patients, highlighted the role of INSTI-based regimens. Dolutegravir (DTG) in combination with abacavir/lamivudine (ABC/3TC) is one of these preferred regimens in multiple clinical scenarios, including treatment-naive and treatment-experienced patients. AREAS COVERED In this article we describe the coformulation of ABC/3TC/DTG in a fixed-dose combination (FDC) approved in September 2014 for the treatment of HIV infection. We focused our research on the efficacy and safety data resulting from phase 2 and 3 clinical study, particularly on the results of both SPRING (1 and 2) and SINGLE studies. EXPERT OPINION Triple combination therapy with ABC/3TC/DTG should be considered among the initial options for treatment-naive patients, being effective, well tolerated, with a high genetic barrier to resistance along with a convenient once-daily administration. In treatment-experienced patients the single-tablet regimen (STR) based on ABC/3TC/DTG could be used as simplification strategy in subjects with sustained viral suppression, as the high genetic barrier of DTG should ensure a safe switch from both NNRTI or PI based regimens.

Patient-Reported Outcomes After a Switch to a Single-Tablet Regimen of Rilpivirine, Emtricitabine, and Tenofovir DF in HIV-1-Positive, Virologically Suppressed Individuals: Additional Findings From a Randomized, Open-Label, 48-Week Trial. PATIENT-PATIENT CENTERED OUTCOMES RESEARCH 2016; 8:257-67.

Abstract
Background Patient-reported outcomes (PROs) can provide important information about treatment tolerability in HIV-1-infected patients. Objective The aim of this study was to evaluate PROs following switching from a boosted protease inhibitor-based regimen to the single-tablet regimen (STR) of rilpivirine/emtricitabine/tenofovir disoproxil fumarate (RPV/FTC/TDF) in the 48-week open-label Switching Boosted PI to Rilpivirine in Combination with Truvada as a Single-Tablet Regimen (SPIRIT) trial. Methods In the open-label SPIRIT trial, patients were randomized to receive an STR of RPV/FTC/TDF (n = 317) for 48 weeks or stay on their baseline regimen of a ritonavir-boosted protease inhibitor and two nucleoside/nucleotide analog reverse transcriptase inhibitors (PI + RTV + 2NRTIs, n = 159) for 24 weeks before switching to RPV/FTC/TDF for another 24 weeks. PRO assessments included the HIV Treatment Satisfaction Questionnaire (TSQ) and the HIV Symptom Index Questionnaire (SIQ). Results At week 24, the mean HIV TSQ improvement from baseline was significantly greater in the RPV/FTC/TDF group than the PI + RTV + 2NRTIs group (p < 0.001). On the HIV SIQ, the percentage of patients reporting a shift from ‘symptom’ to ‘no symptom’ was significantly greater with RPV/FTC/TDF treatment compared with PI + RTV + 2NRTIs for all items (all p ≤ 0.01), with total within-group occurrence of 13/20 symptoms significantly decreasing from baseline for RPV/FTC/TDF patients. In the delayed switch group, significantly fewer patients reported diarrhea and sleep problems at week 48 vs. week 24. Conclusions These data suggest that switching to the STR RPV/FTC/TDF from a PI-based multi-pill regimen is associated with greater patient-reported treatment satisfaction and improved tolerability in HIV-1-infected, virologically suppressed individuals.

Abstract
OBJECTIVE To evaluate the efficiency of single-tablet regimens (STR) and multiple-tablet regimens (MTR) with exactly the same or different components. METHODS A study was conducted on HIV-1-infected antiretroviral-naïve patients from 6 Spanish or French centers, who were started on treatment with STR-Atripla®, or the same components separately (MTR-SC), or a different MTR (MTR-Other). Effectiveness was measured as percentage of HIV-RNA <50copies/mL at 48 weeks (ITT). Efficiency was the ratio between costs (direct cost of antiretrovirals plus outpatient visits, hospital admissions, and resistance tests) and effectiveness. RESULTS The study included a total of 2773 patients (759 STR-Atripla®, 483 MTR-SC, and 1531 MTR-Other). Median age was 37 years, 15% were HCV co-infected, 27% had a CD4+ count <200cells/μL, and 30% had viral load ≥100.000copies/mL. The duration of the assigned treatment was longer for STR-Atripla® (P<.0001). Response rates (adjusted for CD4+ count, viral load, and clustered on hospitals) at 48 weeks were 76%, 74%, and 62%, respectively (P<.0001). Virological failure was more common in MTR patients (P=.0025), and interruptions due to intolerance with MTR-Other (P<.0001). Cost per responder at 48 weeks (efficiency) was €12,406 with STR-Atripla®, €11,034 with MTR-SC (0.89 [0.82, 0.99] times lower), and €18,353 (1.48 [1.38, 1.61] times higher) with MTR-Other. CONCLUSIONS STR-Atripla® and MTR-SC regimens showed similar effectiveness, but virological failure rate was lower with STR-Atripla. MTR-SC, considered less convenient, had a marginally better efficiency, mainly due to lower direct costs. MTR-Other regimens had both a worse effectiveness and efficiency. Similar efficiency analyses adjusting for baseline characteristics should be recommended for new STRs.

Abstract
INTRODUCTION There are multiple reasons to switch from a virologically successful antiretroviral regimen. Some of them are related to toxicity. Lately, combination antiretroviral treatment (cART) switches have often been related to drug-drug interactions which may also eventually entail safety issues as well. AREAS COVERED The purpose of this review is to analyze causes of switching between virologically successful cART regimes related to safety issues. The most relevant papers were selected and summarized. EXPERT OPINION Switching cART has been a popular strategy to address safety issues throughout the antiretroviral era. The myriad of switching studies have paralleled the study and release into clinical practice of new antiretroviral drugs with different and often improved safety profiles. Most of them have been successful in improving antiretroviral toxicity while keeping HIV replication under control. However, it should be taken into account that, whenever a new drug is given, there is a possibility of new drug-related toxicity. Notwithstanding that, an increase in cART switching is foreseen, given the fact that we have a wide antiretroviral drug armamentarium and that people living with HIV are ageing and thus more prone to developing age-related co-morbidities whose therapies may entail new interactions and eventually new toxicities.

Abstract
We are concerned with the development of novel anti-infectives with dual antibacterial and antiretroviral activities for MRSA/HIV-1 co-infection. To achieve this goal, we exploited for the first time the mechanistic function similarity between the bacterial RNA polymerase (RNAP) "switch region" and the viral non-nucleoside reverse transcriptase inhibitor (NNRTI) binding site. Starting from our previously discovered RNAP inhibitors, we managed to develop potent RT inhibitors effective against several resistant HIV-1 strains with maintained or enhanced RNAP inhibitory properties following a structure-based design approach. A quantitative structure-activity relationship (QSAR) analysis revealed distinct molecular features necessary for RT inhibition. Furthermore, mode of action (MoA) studies revealed that these compounds inhibit RT noncompetitively, through a new mechanism via closing of the RT clamp. In addition, the novel RNAP/RT inhibitors are characterized by a potent antibacterial activity against S. aureus and in cellulo antiretroviral activity against NNRTI-resistant strains. In HeLa and HEK 293 cells, the compounds showed only marginal cytotoxicity.

Abstract
The cost of HIV care in European countries is high. Direct medical costs, in France, have been estimated at 500,000 Euros per patient's lifetime (20,000 Euros/year/patient). Overall, 73% of these costs are related to antiretroviral treatments. In the current financial crisis context, some European countries are beginning to make economic decisions on the drugs to be used. These approaches are likely to become more frequent. It is obviously essential to prescribe the most effective, appropriate, best tolerated, and easy-to-use antiretroviral treatments to patients. However, while taking the above into consideration, and if various treatment options or combinations are available, cost should also be considered in the treatment choice. One may thus reflect on the use of generic antiretroviral agents as they have just been launched in France. We aimed to review the cost and cost-effectiveness of generic antiretroviral drugs and to review treatment strategies other than generic drugs that could help reduce HIV-related costs. HIV clinicians should consider treatment costs to avoid any future coercive measures.

Abstract
BACKGROUND Nucleoside reverse transcriptase inhibitor (NRTI)-sparing antiretroviral therapies may be useful in HIV-infected patients with resistance or intolerance to this class. METHODS We performed an observational study of patients on suppressive antiretroviral therapy containing two NRTIs plus one ritonavir-boosted protease inhibitor who switched to a dual regimen containing raltegravir (400 mg twice daily) and darunavir/ritonavir (800/100 mg once daily) and were followed-up for 48 weeks. RESULTS As a whole, 82 patients were enrolled. Mean duration of current regimen was 4.6 years and mean duration of plasma HIV RNA < 50 copies/mL before the switch was 46.2 months. Reason for simplification was toxicity in 76 patients and resistance to NRTIs in 13. After switching, the percentage of patients with HIV RNA < 50 copies/mL at week 48 was 92.7% in the intent-to-treat-exposed analysis and 97.6% in the per-protocol analysis. The switch led to a significant reduction in the mean triglyceride value (-85.2 mg/dL), in the prevalence of tubular proteinuria (-56%) and in the mean level of interleukin-6 (-0.94 pg/mL), with a significant increase in the mean phosphoremia (+0.58 mg/dL). Mean trough concentrations of both raltegravir and darunavir were within the therapeutic range. Two patients (2.4%) had virological failure due to suboptimal adherence and 4 subjects (4.9%) discontinued treatment due to adverse events, but no patients experienced Grade 3 or 4 adverse events. CONCLUSION In our study, simplification to a dual therapy containing raltegravir plus darunavir/ritonavir after 48 weeks maintained viral suppression in more than 90% of patients and showed a good tolerability with a favourable effect on proteinuria, ipophosphoremia, and lipid metabolism.

Abstract
HIV/AIDS has been an extremely difficult pandemic to control. However, with the advent of antiretroviral therapy (ART), HIV has now been transformed into a chronic illness in patients who have continued treatment access and excellent long-term adherence. Existing indications for ART initiation in asymptomatic patients were based on CD4 levels; however, recent evidence has broken the shackles of CD4 levels. Early initiation of ART in HIV patients irrespective of CD4 counts can have profound positive impact on morbidity and mortality. Early initiation of ART has been found not only beneficial for patients but also to community as it reduces the risk of transmission. There have been few financial concerns about providing ART to all HIV-positive people but various studies have proven that early initiation of ART not only proves to be cost-effective but also contributes to economic and social growth of community. A novel multidisciplinary approach with early initiation and availability of ART at its heart can turn the tide in our favor in future. Effective preexposure prophylaxis and postexposure prophylaxis can also lower transmission risk of HIV in community. New understanding of HIV pathogenesis is opening new vistas to cure and prevention. Various promising candidate vaccines and drugs are undergoing aggressive clinical trials, raising optimism for an ever-elusive cure for HIV. This review describes various facets of tectonic shift in management of HIV.

Availability of a single source review of once-daily fixed-dose single tablet regimen (STR) and multiple tablet fixed-dose regimen (MTR) would optimally inform healthcare providers and policy makers involved in the management of population with human immunodeficiency virus (HIV).We conducted a meta-analysis of published literature to compare patient adherence, clinical, and cost outcomes of STR to MTR.Published literature in English between 2005 and 2014 was searched using Embase, PubMed (Medline in-process), and ClinicalTrials.Gov databases. Two-level screening was undertaken by 2 independent researchers to finalize articles for evidence synthesis. Adherence, efficacy, safety, tolerability, healthcare resource use (HRU), and costs were assessed comparing STR to MTR. A random-effects meta-analysis was performed and heterogeneity examined using meta-regression.Thirty-five articles were identified for qualitative evidence synthesis, of which 9 had quantifiable data for meta-analysis (4 randomized controlled trials and 5 observational studies). Patients on STR were significantly more adherent when compared to patients on MTR of any frequency (odds ratio [OR]: 2.37 [95% CI: 1.68, 3.35], P < 0.001; 4 studies), twice-daily MTR (OR: 2.53 [95% CI: 1.13, 5.66], P = 0.02; 2 studies), and once-daily MTR (OR: 1.81 [95% CI: 1.15, 2.84], P = 0.01; 2 studies). The relative risk (RR) for viral load suppression at 48 weeks was higher (RR: 1.09 [95% CI: 1.04, 1.15], P = .0003; 3 studies) while RR of grade 3 to 4 laboratory abnormalities was lower among patients on STR (RR: 0.68 [95% CI: 0.49, 0.94], P = 0.02; 2 studies). Changes in CD4 count at 48 weeks, any severe adverse events (SAEs), grade 3 to 4 AEs, mortality, and tolerability were found comparable between STR and MTR. Several studies reported significant reduction in HRU and costs among STR group versus MTR.Study depicted comparable tolerability, safety (All-SAE and Grade 3-4 AE), and mortality and fewer Grade 3 to 4 lab abnormalities and better viral load suppression and adherence among patients on FDC-containing STR versus MTR; literature depicted favorable HRU and costs for STRs.These findings may help decision makers especially in resource-poor settings to plan for optimal HIV disease management when the choice of both STRs and MTRs are available.

Abstract
BACKGROUND The antiretroviral regimens including tenofovir and a ritonavir-boosted protease inhibitor (r/PI) have been associated with a reduced bone mineral density (BMD), increased bone turnover markers and renal tubular dysfunction. METHODS An observational, prospective study was performed including HIV-1-infected, virologically suppressed patients treated with tenofovir/emtricitabine plus an r/PI for at least 12 months who switched to raltegravir plus nevirapine. The primary end point was changes after 48 weeks in estimated glomerular filtration rate (eGFR), prevalence of tubular dysfunction, BMD and concentration of two serum markers of bone turnover: collagen type-1 cross-linked C-telopeptide (CTX) and bone-specific alkaline phosphatase (BAP). RESULTS A total of 46 patients were enrolled: 78% were male, 96% were Caucasian, the mean age was 45 years and the mean CD4(+) T-lymphocyte count was 681 cells/mm(3). A renal impairment was present in 72% of patients and was the main reason for the switch. After 48 weeks, prevalence of proximal tubular dysfunction decreased significantly (-72%; P<0.001), whereas the mean value of eGFR did not change significantly. At the same time, after 48 weeks a significant increase in both lumbar spine and total hip BMD, T-score and Z-score was reported (+11.5% in lumbar spine T-score; P<0.001), and there was a significant reduction in both CTX and BAP mean serum concentrations (-15% and -13%, respectively; P<0.001). Two (4.3%) patients had virological failure due to suboptimal adherence and one (2.2%) subject discontinued treatment due to a skin rash. CONCLUSIONS Switching virologically suppressed patients from tenofovir/emtricitabine plus one r/PI to raltegravir plus nevirapine after 48 weeks significantly improved proximal tubular function, increased BMD and reduced serum markers of bone turnover.

Radiother Oncol 2015; 116:323-30. [PMID: 26183311 DOI: 10.1016/j.radonc.2015.07.002] [Citation(s) in RCA: 10] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/16/2013] [Revised: 05/24/2015] [Accepted: 07/02/2015] [Indexed: 11/30/2022]
Abstract
PURPOSE As the incidence of cancer is rising in HIV-1-infected patients, radiotherapy is used more frequently in this patient group. Strong radiation induced side effects have been reported in single patients on antiretroviral therapy. Thus we investigated whether HIV-1 itself or antiretroviral drugs could enhance radiosensitivity in patients. METHODS AND MATERIALS Radiosensitivity after in vitro irradiation of blood lymphocytes was tested in 196 individuals (80 HIV-1-infected patients and 116 healthy controls and cancer patients) using a three color fluorescence in situ hybridization approach to analyze chromosomal aberrations (B/M). Additionally, the NNRTI efavirenz and the NRTIs tenofovir and emtricitabine were tested for radiosensitizing effects in vitro. RESULTS Lymphocytes from HIV-1-infected patients in the NNRTI + NRTI group were significantly more sensitive to ionizing radiation than in the other groups (patients without treatment or with NRTI + PI or HIV-negative controls). In vitro the triple medication efavirenz, tenofovir and emtricitabine leads to a reduced survival fraction and an increased activation of the DNA repair proteins H2AX, Nbs, Atm and 53BP1 in combination with ionizing radiation. CONCLUSIONS HIV-1 treatment with NNRTI containing therapy regimes possibly sensitizes a subgroup of patients to ionizing radiation. Individual radiosensitivity of HIV-1-infected patients on HAART including NNRTI should be tested before starting radiotherapy.

Enferm Infecc Microbiol Clin 2015; 33:543.e1-43. [PMID: 25959461 DOI: 10.1016/j.eimc.2015.03.016] [Citation(s) in RCA: 5] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/24/2015] [Accepted: 03/08/2015] [Indexed: 11/20/2022]
Abstract
OBJECTIVE This consensus document is an update of combined antiretroviral therapy (cART) guidelines and recommendations for HIV-1 infected adult patients. METHODS To formulate these recommendations, a panel composed of members of the AIDS Study Group and the AIDS National Plan (GeSIDA/Plan Nacional sobre el Sida) reviewed the efficacy and safety advances in clinical trials, and cohort and pharmacokinetic studies published in medical journals (PubMed and Embase) or presented in medical scientific meetings. The strength of the recommendations, and the evidence that supports them, are based on modified criteria of the Infectious Diseases Society of America. RESULTS In this update, cART is recommended for all patients infected by type 1 human immunodeficiency virus (HIV-1). The strength and level of the recommendation depends on the CD4+T-lymphocyte count, the presence of opportunistic diseases or comorbid conditions, age, and prevention of transmission of HIV. The objective of cART is to achieve an undetectable plasma viral load. Initial cART should always comprise a combination of 3 drugs, including 2 nucleoside reverse transcriptase inhibitors, and a third drug from a different family. Three out of the ten recommended regimes are regarded as preferential (all of them with an integrase inhibitor as the third drug), and the other seven (based on a non-nucleoside reverse transcriptase inhibitor, a ritonavir-boosted protease inhibitor, or an integrase inhibitor) as alternatives. This update presents the causes and criteria for switching cART in patients with undetectable plasma viral load, and in cases of virological failure where rescue cART should comprise 3 (or at least 2) drugs that are fully active against the virus. An update is also provided for the specific criteria for cART in special situations (acute infection, HIV-2 infection, and pregnancy) and with comorbid conditions (tuberculosis or other opportunistic infections, kidney disease, liver disease, and cancer). CONCLUSIONS These new guidelines update previous recommendations related to cART (when to begin and what drugs should be used), how to monitor and what to do in case of viral failure or drug adverse reactions. cART specific criteria in comorbid patients and special situations are equally updated.

Abstract
We sought to review the effectiveness of interventions designed to improve adherence to antiretroviral therapy (ART) from studies included in a recent Cochrane review that reported a clinical and an adherence outcome, with at least 80% follow-up for 6 months or more. Data were extracted independently and in duplicate, with an adjudicator for disagreements. Risk of bias was assessed using the Cochrane Risk of Bias tool. Of 182 relevant studies in the Cochrane review, 49 were related to ART. Statistical pooling was not warranted due to heterogeneity in interventions, participants, treatments, adherence measures and outcomes. Many studies had high risk of bias in elements of design and outcome ascertainment. Only 10 studies improved both adherence and clinical outcomes. These used the following interventions: adherence counselling (two studies); a once-daily regimen (compared to twice daily); text messaging; web-based cognitive behavioral intervention; face-to-face multi-session intensive behavioral interventions (two studies); contingency management; modified directly observed therapy; and nurse-delivered home visits combined with telephone calls. Patient-related adherence interventions were the most frequently tested. Uniform adherence measures and higher quality studies of younger populations are encouraged.

Efficacy, safety and pharmacokinetics of tenofovir disoproxil fumarate in virologic-suppressed HIV-infected children using weight-band dosing. Pediatr Infect Dis J 2015; 34:392-7. [PMID: 25760566 DOI: 10.1097/inf.0000000000000633] [Citation(s) in RCA: 20] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Indexed: 11/26/2022]
Abstract
BACKGROUND Tenofovir disoproxil fumarate (TDF) is approved for children but concerns remain about long-term renal and bone toxicity. We evaluated the efficacy, safety and pharmacokinetics of TDF in treatment-experienced children during 96 weeks. METHODS This was a prospective, open-label study in HIV-infected children 3-18 years of age (≥15 kg), with viral suppression on their first-line regimen without tenofovir. Children were given TDF/lamivudine/efavirenz once daily at entry; TDF was prescribed according to weight bands. Age-, gender- and CD4-matched controls receiving TDF-sparing regimens were concomitantly enrolled. Tenofovir pharmacokinetic assessment was performed at week 4. CD4 counts, HIV-1 RNA viral load and safety assessments were determined at baseline, 24, 48 and 96 weeks. RESULTS Eighty children were enrolled (40 per group); 35 (44%) were male. Median age was 12.2 (range 3.1-17.7) years. The median administered dose was 214 mg/m. Tenofovir geometric mean AUC0-24 hours, Cmax and C24 hours were 2.66 [90% confidence interval (CI) 2.49-2.84] μg hours/mL, 0.26 (0.24-0.29) μg/mL and 0.057 (0.052-0.062) μg/mL, respectively. Estimated glomerular filtration rate did not significantly change overtime. The fractional excretion of calcium slightly increased but fractional excretion of phosphate was unchanged among children in TDF group. The bone mineral density Z score decreased in the first 24 weeks of TDF treatment and was stable afterward. The TDF group had lower cholesterol levels (P = 0.001). Thirty-nine of 40 children remained virologically suppressed. No serious adverse event related to tenofovir. CONCLUSION TDF substitution in children and adolescents who were otherwise stable while receiving a first-line nonnucleoside reverse transcriptase inhibitor-based regimen achieved adequate exposure without clinically significant renal or bone adverse events over 96 weeks. While reassuring, these preliminary safety findings may not exclude delayed effects on renal function and bone density.
