Although the introduction of direct-acting antiviral drugs (DAAs) has greatly enhanced the prognosis for hepatitis C, the timely diagnosis and treatment of hepatitis C virus (HCV) infection remain a severe challenge in China.

This retrospective study involved 368,577 patients tested for hepatitis C antibodies from 2020 to 2023 at a large tertiary hospital in South China. It primarily focused on analyzing the prevalence of Anti-HCV and HCV RNA and further evaluated the impact of the 'Hepatitis C-Free Hospital' initiative.

Between 2020 and 2023, this large tertiary hospital in South China reported an overall Anti-HCV positivity rate of 1.08%, with males (1.06%) higher than females (0.57%). In particular, the highest rates were observed in males aged 40-49 (2.24%) and females aged 60-69 (1.00%). There was a gradual decline in the Anti-HCV positivity rate over time. As for HCV RNA testing, it indicated an overall positivity rate of 30.95%, more prevalent in males. Significantly, the 'Hepatitis C-Free Hospital' initiative increased HCV RNA testing and treatment completion rates, with sustained virological response (SVR) rates escalating from 92.86% to 99.61%.

This study identified specific patient groups with high HCV positivity rates. Additionally, the 'Hepatitis C-Free Hospital' initiative significantly increased HCV RNA testing and treatment rates, providing a feasible model for regional HCV elimination.

People with opioid agonist therapy (OAT) represent a population with an increased hepatitis C (HCV) prevalence. Recent studies provide strong evidence regarding effective HCV treatment outcomes and low levels of reinfection in this population. Increased access to HCV care for people with OAT is essential to reach the WHO goal of eliminating HCV as a major public health threat by 2030.

The Maria OAT clinic, located in central Stockholm, provides OAT for approximately 500 patients. The majority have a history of injection drug use. In October 2017, psychiatrist-led HCV treatment was initiated, with remote consultation support from the local infectious diseases clinic. All OAT staff participated in HCV-specific education to increase HCV awareness. To evaluate HCV treatment outcomes for this model of care, we examined sustained virological response (SVR) and reinfection rates between January 2018 and December 2022.

Between October 2017 and June 2022, 133 participants received HCV treatment through weekly administrations or directly observed treatment. 72% were men, and the overall mean age was 44.7 years. Six participants were retreated, giving a total of 139 treatment initiations. All were HCV RNA negative at end of treatment, and 88% reached SVR. A total of 11 reinfections post SVR were noted, with a reinfection rate of 7.3/100 person-years (95% CI 4.1-12.9).

Overall, successful HCV treatment results and levels of reinfections consistent with the literature were achieved. Bringing HCV diagnostics and treatment to an OAT clinic constitutes a good example of enhancing the HCV continuum of care. Furthermore, HCV treatment education for psychiatrists, addiction specialists and staff at OAT clinics makes HCV care more sustainable, as specifically noted during the COVID-19 pandemic. This successful model of care, introducing HCV treatment by psychiatrists on-site at OAT clinics, has now been further implemented at other OAT clinics in Stockholm.

In 2023, the Italian healthcare system launched HCV screening targeting subjects born in 1968-1989. However, subjects > 50 yrs also need screening. In addition, existence of gender gaps in HCV diagnosis and treatment has been suggested. Our aim was to identify undiagnosed individuals outside the age groups to whom the screening is offered and to gather data about gender gaps. This is a prospective, opportunistic micro-elimination initiative based on a network between 24 Apulian pharmacies and our center. Between 01/07/2022 and 01/03/2024, subjects aged 55 to 85, accessing pharmacies were offered HCVOraQuick tests (F/M 1:1) and administered ad-hoc questionnaires. In total, 13,042 screening were carried out. Mean age was 64.9 (± 7.6), 51.1% females. Overall, 1.1% were anti-HCV positive: mean age 68.3 (± 10.3), 44.9% females. Seroprevalence was higher in males (p < 0.00001), elderly (p < 0.00001) and unknown transmission route (p = 0.0009). HCV-RNA was detectable in 67.4% of seropositive. They were 67.5 (± 10.7) yrs old, mainly males (55.1%). HCV-RNA prevalence was 0.8%, higher in elderly (p = 0.0003) and unknown transmission route (p = 0.0007). Overall, 90% were linked-to-treatment. Differences in patients profiles should be considered to guide policy and more inclusive treatment approaches. Gender differences in screening response and rates of active infections underscore the need for gender-targeted intervention.

Liver cancer is the third leading cause of cancer-related deaths globally, with incident cases expected to rise from 905,700 in 2020 to 1.4 million by 2040. Hepatocellular carcinoma (HCC) accounts for about 80% of all primary liver cancers. Viral hepatitis and chronic excessive alcohol consumption are major risk factors for HCC, but metabolic dysfunction-associated steatotic liver disease is also becoming a dominant cause. The increasing numbers of cases of HCC and changes in risk factors highlight the urgent need for updated and targeted prevention strategies. Preventive interventions encompass strategies to decrease the burden of chronic liver diseases and their progression to HCC. These strategies include nutritional interventions and medications that have shown promise in preclinical models. Although prevailing approaches focus on treating chronic liver disease, leveraging a wider range of interventions represents a promising area to safeguard at-risk populations. In this Review, we explore existing evidence for preventive strategies by highlighting established and potential paths to reducing HCC risk effectively and safely, especially in individuals with chronic liver diseases. We categorize the preventive strategies by the mechanism of action, including anti-inflammatory, antihyperglycaemic, lipid-lowering, nutrition and dietary, antiviral, and antifibrotic pathways. For each category, we discuss the efficacy and safety information derived from mechanistic, translational, observational and clinical trial data, pinpointing knowledge gaps and directions for future research.

Highly effective direct-acting antiviral (DAA) therapies have transformed the landscape of hepatitis C virus (HCV) treatment. However, there continues to be limited data regarding the efficacy and safety of required in-person clinic visits (standard monitoring) versus completely telehealth clinic visits (minimal monitoring) during HCV therapy, which could delay practice adoption.

This study aimed to assess the rates of undetectable HCV ribonucleic acid (RNA) in sustained viral load 12 weeks after therapy (SVR12) in standard versus minimal monitoring approaches during DAA.

A 12-month, single-center retrospective cohort study was conducted in treatment-naïve HCV-infected adults who received DAA therapy between May 1, 2020, and April 30, 2021. The standard monitoring group had ≥1 in-person clinic visit with HCV RNA laboratory monitoring during DAA treatment. The minimal monitoring group had entirely telehealth visits without HCV RNA laboratory monitoring during treatment. Both groups received telephonic touchpoints throughout DAA treatment from a clinical pharmacist practitioner and a nurse care coordinator. The primary outcome was SVR12.

From May 2020 to April 2021, 133 patients with HCV met inclusion criteria and were treated with DAA (standard, n = 56; minimal, n = 77), with no differences in baseline demographics. Overall, total encounters during DAA treatment remained statistically significant in the standard than minimal monitoring group (standard, 2.1 ± 0.8, vs. minimal, 1.7 ± 0.9; P < .01). Although minimal monitoring had higher loss to follow-up rates (standard, 7.1%, vs. minimal, 18.2%; P = 0.06), the modified intention-to-treat analysis showed no differences in sustained virologic response (SVR) between standard and minimal monitoring approaches (standard, 98.1%, n = 51, vs. minimal, 95.3%, n = 60; P = 0.41).

This single-center retrospective cohort study demonstrated that minimal monitoring during HCV treatment was as effective in achieving SVR cure rates as standard monitoring. Eliminating required in-person clinic visits during DAA therapy alongside a collaborative approach may play a major role in overcoming barriers to HCV care in select patients.

The World Health Organization (WHO) aims to eliminate hepatitis C virus (HCV) by 2030; therefore, widespread HCV screening is required. The WHO recommends HCV self-testing (HCVST) as a new approach. We aimed to evaluate disease burden reduction using the HCVST screening strategy and identify the most cost-effective approach.

We developed a dynamic open-cohort Markov model to assess the long-term effects and costeffectiveness of HCVST in the Republic of Korea from 2024 to 2030. Strategies for comparison included universal, birth cohort, high-risk group screening, and no screening, focusing on the following: (1) incremental costeffectiveness ratio (ICER) per disability-adjusted life-year (DALY) saved; (2) severe liver disease cases; and (3) liverrelated death reduction.

Universal HCVST screening is the most effective strategy for achieving the WHO goal by 2030, substantially lowering the incidence of severe liver disease by 71% and preventing liver-related deaths by 69%, thereby averting 267,942 DALYs. Moreover, with an ICER of US$8,078 per DALY and high cost-effectiveness, the sensitivity results prove that cost-effectiveness is robust. Although high-risk group screening offers the lowest cost compared with other strategies, its effectiveness in preventing severe liver disease is minimal, falling short of the current WHO goal.

Our study confirms that universal HCVST screening is a cost-effective strategy aligned with the WHO goal to eliminate HCV by 2030. Despite its higher costs compared to risk-based screening, the disease burden can be significantly reduced by providing effective HCVST access to individuals who might otherwise not be tested.

Direct-acting antivirals (DAAs) to treat hepatitis C virus (HCV) infection offer an opportunity to eliminate the disease. This study aimed to identify and relink to care HCV patients previously lost to medical follow-up in the health area of Pontevedra and O Salnés (Spain) using an artificial intelligence-assisted system.

Active retrospective search of previously diagnosed HCV cases recorded in the Galician Health Service proprietary health information exchange database using the Herramientas para la EXplotación de la INformación (HEXIN) application.

Out of 99 lost patients identified, 64 (64.6%) were retrieved. Of these, 62 (96.88%) initiated DAA treatment and 54 patients (87.1%) achieved a sustained virological response. Mean time from HCV diagnosis was over 10 years. Main reasons for loss to follow-up were fear of possible adverse effects of treatment (30%) and mobility impediments (21%). Among the retrieved patients, almost one in three presented advanced liver fibrosis (F3) or cirrhosis (F4) at evaluation. In sum, HCV patients lost to follow-up can be retrieved by screening past laboratory records. This strategy promotes the achievement of HCV elimination goals.

The rising prevalence of hepatitis C infections among individuals of reproductive age further emphasizes the importance of evidence-based management of hepatitis C virus (HCV) during pregnancy to minimize perinatal transmission and to optimize maternal and fetal outcomes. In this review, we discuss the most recent recommendations on the management of HCV in pregnancy, including recommendations for screening and treatment during pregnancy and the postpartum period, as well as infant management to reduce perinatal transmission of HCV.

Current guidelines recommend universal HCV screening during each pregnancy. With varying guidance regarding the use of direct-acting antivirals (DAAs) during pregnancy, recent studies have focused on the safety and efficacy of DAA initiation during pregnancy. Additionally, there has been an increased focus on improving treatment rates in the postpartum period through innovative linkage to care efforts, telemedicine, and additional efforts reducing barriers to care for patients.

With the advent of direct acting antivirals (DAAs) the World Health Organisation (WHO) adopted global strategy to eliminate hepatitis C virus (HCV) infection by 2030. In Europe, people who inject drugs (PWID) account for the majority of new cases, however testing and treatment remain suboptimal. The aim was to monitor progress in HCV policy and cascade-of-care for PWID, led by the civil society organisations (CSO) that provide harm reduction services for PWID across Europe.

In period 2020-2023, CSOs representing focal points of Correlation-European Harm Reduction Network were annually invited to complete online questionnaire on use/impact of HCV test-and-treat guidelines for PWID, availability/functioning of continuum-of-care, and role/limitations of harm reduction services for PWID. A retrospective longitudinal analysis of responses to questions answered each year by the same respondents was performed, and a comparison among the studied years was made.

Twenty-five CSOs from cities in 25 European countries were included and responded to 25 questions. Between 2020 and 2023, there was positive trend in number of HCV treatment guidelines, separate guidelines for PWID, and their positive impact on acess to testing/treatment (24/25, 5/25, and 16/25 in 2023, respectively). DAAs were available in all countries, predominantly prescribed by specialist physicians only (slight increase at primary care), with restrictions including active drug use, stage of liver fibrosis or/and reimbursement policies (2/25, 4/25, and 3/25 in 2023, respectively). A decrease in HCV testing sites was noted. Treatment was consistently most common at clinical settings, however an increase outside the specialist settings was detected, particularly in prisons (12/25 and 15/25 in 2020-2021, respectively). Comparing 2022-2023, number of HCV-testing services increased in many cities with positive dynamic in nearly all the settings; increase in treatment at harm reduction services/community centres was noted (6/25 to 8/25, respectively). Between 2020 and 2023 the frequency of various limitations to CSOs addressing HCV was oscillating, presenting an increase between 2022 and 2023 (9/25 to 14/25, respectively).

The overall progress towards WHO HCV elimination goals across Europe remains insufficient, most probably also due to the influence of Covid-19 pandemic. Further improvements are needed, also by including CSOs for PWID in continuum-of-care services, and in monitoring progress.

Risk stratification for patients with a higher risk of hepatocellular carcinoma (HCC) is crucial. We aimed to investigate the role of the Fibrosis-4 (FIB-4) index in predicting chronic hepatitis C (CHC)-related HCC.

A retrospective cohort study consecutively included treatment-naive CHC patients receiving longitudinal follow-up at the National Taiwan University Hospital from 1986 to 2014. The clinical data were collected and traced for HCC development. Multivariable Cox proportional hazard regression analysis was used to investigate the predictors for HCC.

A total of 1285 patients in the ERADICATE-C cohort were included. The median age was 54, 56% were females, and 933 had HCV viremia. There were 33%, 38%, and 29% of patients having FIB-4 index <1.45, 1.45-3.25, and ≥3.25, respectively. After a median of 9-year follow-up, 186 patients developed HCC. Multivariable analysis revealed that older age, AFP≥20 ng/mL, cirrhosis, and a higher FIB-4 index were independent predictors for HCC. Compared with patients with FIB-4 index <1.45, those with FIB-4 1.45-3.25 had a 5.51-fold risk (95% confidence interval [CI]: 2.65-11.46), and those with FIB-4 ≥ 3.25 had 7.45-fold risk (95% CI: 3.46-16.05) of HCC. In CHC patients without viremia, FIB-4 index 1.45-3.25 and FIB-4 ≥ 3.25 increased 6.78-fold and 16.77-fold risk of HCC, respectively, compared with those with FIB-4 < 1.45.

The baseline FIB-4 index can stratify the risks of HCC in untreated CHC patients, even those without viremia. The FIB-4 index should thus be included in the management of CHC.

HCV infection poses a global health threat, with significant morbidity and mortality. This study examines HCV trends in a large Italian region from 2015 to 2022, considering demographic changes, evolving clinical profiles, treatment regimens and outcomes, including the impact of the COVID-19 pandemic. This multicentre retrospective study analysed demographics, clinical histories and risk factors in 6882 HCV patients. The study spanned before and after the direct-acting antiviral (DAA) era, and the COVID-19 period, focusing on treatment outcomes (SVR12, non-SVR12 and patients lost to follow-up). Statistical methods included ANOVA, multinomial logistic regression, Kruskal-Wallis test and chi-square analysis, and were conducted adhering to the intention-to-treat (ITT) principle. The cohort, mainly Italian males (average age 58.88), showed Genotype 1 dominance (56.6%) and a high SVR12 rate (97.5%). The pandemic increased follow-up losses, yet SVR12 rates remained stable, influenced by factors like age, gender, cirrhosis and comorbidities. Despite COVID-19 challenges, the region sustained high SVR12 rates in HCV care, emphasising the importance of sustained efforts in HCV care. Continuous screening and targeted interventions in high-risk populations are crucial for achieving WHO elimination targets. The study highlights the resilience of HCV care during the pandemic and provides insights for future public health strategies.

Young adult (18-30 years) people who inject drugs (PWID) face high hepatitis C virus (HCV) prevalence. In San Francisco, where >60% of PWID lack stable housing, barriers hinder HCV treatment access. We assessed progress towards the World Health Organization's (WHO) HCV elimination goal of an 80% reduction in incidence over 2015-2030, focusing on young (YPWID) and unstably housed PWID in San Francisco.

We developed a dynamic HCV transmission model among PWID, parameterized and calibrated using bio-behavioural survey datasets from San Francisco. This included 2018 estimates for the antibody-prevalence among PWID (77%) and care cascade estimates for HCV for YPWID (72% aware of their status and 33% ever initiating treatment). Based on programmatic data, we assumed a 53.8% reduction in testing and 40.7% decrease in treatment from 2020 due to the COVID-19 pandemic, which partially rebounded from April 2021 with testing rates then being 31.1% lower than pre-pandemic rates and treatment numbers being 19.5% lower. We simulated different scenarios of how services changed after the pandemic to project whether elimination goals would be met.

Continuing post-pandemic rates of testing and treatment, the model projects an 83.3% (95% credibility interval [95% CrI]:60.6-96.9%) decrease in incidence among PWID over 2015-2030 to 1.5/100pyrs (95% CrI:0.3-4.4) in 2030. The probability of achieving the elimination goal by 2030 is 62.0%. Among YPWID and unstably housed PWID, the probability of achieving the elimination goal by 2030 is 54.8 and 67.6%, respectively. Importantly, further increasing testing and treatment rates to pre-pandemic levels by 2025 only results in a small increase in the probability (67.5%) of the elimination goal being achieved among all PWID by 2030, while increased coverage of medication for opioid use disorder among YPWID and/or housing interventions results in the probability of achieving elimination increasing to over 75%.

The COVID-19 pandemic impeded progress toward achieving HCV elimination. Our findings indicate that existing partial rebounds in HCV testing and treatment may achieve the elimination goal by 2030, with an additional scale-up of interventions aimed at YPWID or unstably housed PWID ensuring San Francisco is likely to achieve elimination by 2030.

People who inject drugs (PWID) account for some of the fastest-growing HCV epidemics globally. While individual risk factors for infection are understood, less is known about network and spatial factors critical for elimination strategies. Two thousand five hundred twelve PWID in New Delhi, India, were recruited (2017-19) through network referrals. Biometrics identified duplicates and cross-network linkages. Participants completed semi-annual surveys and blood tests for HCV antibodies and RNA. Poisson regression and network analyses identified predictors of incident HCV and compared network-based intervention approaches. Baseline HCV antibody prevalence was 65.1%, of whom 79.6% were HCV RNA-positive. We observed 92 HCV seroconversions over 382.25 person-years (incidence: 24.1 per 100 person-years). Of the 92 seroconverters, 67% (62) were directly connected to an RNA-positive participant, and all were within one degree of separation from an RNA-positive participant. Individual-level factors associated with seroconversion included age, sexual activity, and injection behaviours. After adjusting for individual-level factors, seroconversion was significantly associated with number of RNA-positive partners (adjusted incidence rate ratio [AIRR] = 1.30) and injecting at a particular venue (AIRR = 2.53). This association extended to indirect ties, with 17% reduced odds of seroconversion for each degree of separation from the venue (AIRR = 0.83). Network analyses comparing intervention strategies found that targeting venues identified more cases compared to a treat-a-friend approach. We observed a fast-growing HCV epidemic driven by viremia within individuals' immediate networks and indirect social and spatial ties, demonstrating the importance of achieving broad, sustained virologic response and rethinking network-based interventions to include venues.

Hepatitis B (HBV) and hepatitis C (HCV) viruses are significant causes of primary liver cancer, responsible for over a million deaths annually. We aimed to develop a screening strategy for viral hepatitis elimination in Spain, aligned with WHO's 2030 objectives.

The CRIVALVIR-FOCUS program, conducted at the Consortium General University Hospital of Valencia, aimed to identify individuals with active blood-borne viral infections through opportunistic population screening. The hospital's Health Department serves more than 280,000 adults.

Of the 31,995 adults screened (52% women; 15% immigrants), HBV prevalence was 0.44%, with higher rates in men (0.57%) than women (0.32%), and notably higher in migrants (1.27%) compared to Spanish nationals (0.30%). The 45-64 age group had the highest HBV prevalence (0.65%). HCV prevalence was 0.35%, again higher in men than women (0.51% vs 0.20%) and in migrants compared to Spanish nationals (0.58% vs 0.31%), with the 45-64 age group showing the highest HCV prevalence (0.76%). From the positive tests, 78.0% (110/141) of HBV cases and 71.4% (80/112) of HCV cases were patients previously unaware of their infections.

Opportunistic screening effectively identifies early cases, potentially enhancing prevention of new infections. Our study highlights the need for targeted interventions for individuals aged 45-64 and migrants. Designing specific screening programs, in collaboration with social workers and cultural mediators, is critical to improve access to care. Training and involving primary care professionals are vital actions for the program's success.

Chronic hepatitis B and C are among the most significant infectious diseases worldwide, and are major risk factors for liver cirrhosis and liver cancer. In Japan, comprehensive hepatitis measures are implemented for the testing and treatment of viral hepatitis, thus enabling the early diagnosis of liver cancer. Nevertheless, patients with decompensated cirrhosis and liver cancer often have unfavorable prognoses and require repetitive long-term treatment. In fiscal year 2018, an integrated policy of medical expense subsidies and research was established in Japan that aimed to alleviate patients' financial burden and launch the clinical registry of advanced liver disease. Over time, updates to the eligibility for the subsidy increased access to patients and has led to an increased number of beneficiaries. Additionally, the accumulation of clinical data in the registry has revealed the treatment choices for these diseases. However, the disparities in efforts across prefectures have also become evident. Raising public awareness of the policy and tightening the multisector healthcare network are keys to success in supporting qualifying patients with advanced liver disease.

The COVID-19 pandemic overwhelmed national health care systems, not least in the context of hepatitis elimination. This study investigates the effects of the pandemic response on the incidence rate, mortality rate, and case fatality rate (CFR) for hepatitis C virus (HCV) cases in China. We extracted the number of hepatitis C cases and HCV-related deaths by month and year for 2015 to 2021 in China and applied two proportional tests to analyze changes in the average yearly incidence rates, mortality rates, and CFRs for 2015 to 2020. We used the autoregressive integrated moving average model to predict these three rates for 2020 based on 2015 to 2019 HCV data. The incidence of hepatitis C decreased by 7.11% and 1.42% (P < .001) in 2020 and 2021, respectively, compared with 2015 to 2019, while it increased by 6.13% (P < .001) in 2021 relative to 2020. The monthly observed incidence in 2020 was significantly lower (-26.07%) than predicted. Meanwhile, no differences in mortality rate or CFR were observed between 2021, 2020, and 2015 to 2019. Our findings suggested that nonpharmaceutical interventions and behavioral changes to mitigate COVID-19 could have reduced hepatitis C incidence and accelerated China's implementation of a plan to eliminate HCV infection.

This study aimed to assess the impact of the COVID-19 pandemic on national surveillance of viral hepatitis in Italy.

Interrupted time series analysis.

Using an interrupted time series analysis with a customised AutoRegressive Integrated Moving Average model on hepatitis cases reported to the Integrated Epidemiological System of Acute Viral Hepatitis from 2006 to 2022, we examined trends in incidence, time to diagnosis and time to epidemiological investigations for hepatitis A, hepatitis B and hepatitis C.

The quarterly incidence of hepatitis B (-0.251, P = 0.05) and hepatitis C (-0.243, P = 0.003) significantly decreased with the onset of the pandemic. Surveillance times for hepatitis B (5.496, P < 0.001) and hepatitis C (35.723, P < 0.001), measured as days lost per quarter, significantly increased 12 and 24 months after the pandemic's start. This aligns with a notable rise in quarterly incidence at 36 months for both (0.032, P = 0.030 for hepatitis B; 0.040, P < 0.001 for hepatitis C).

The decrease in reported cases could be due to an increase in infection prevention control and containment measures put in place in a pandemic context. However, a delay in the initiation of epidemiological investigations was observed, which could lead to a further increase in incidence in the future.

Chronic liver disease presents a significant global health burden, characterized by several etiologies, including metabolic dysfunction-associated steatotic liver disease (MASLD), alcohol-related liver disease (ALD), chronic hepatitis B virus infection, and chronic hepatitis C virus infection. This review explored current epidemiological trends and projections for each etiology, looking into their respective burdens and challenges. MASLD, formerly known as nonalcoholic fatty liver disease, is the most prevalent cause of chronic liver disease, and its global incidence and prevalence are steadily rising. ALD, fueled by increased alcohol consumption, is also on the rise, with concerning implications for future mortality rates. Chronic hepatitis B and C infections remain major public health concerns, particularly in specific regions of the world, necessitating concerted efforts for screening and treatment. The coronavirus disease 2019 (COVID-19) pandemic has impacted the epidemiology of chronic liver disease, exacerbating mortality rates and disrupting healthcare services. Mental health issues arising from the pandemic further complicate the treatment of chronic liver disease, making comprehensive healthcare strategies essential. Despite advancements in treatment, chronic liver disease continues to impose a substantial economic burden, emphasizing the importance of preventive measures and early intervention. In conclusion, ongoing surveillance and research efforts are crucial for understanding and addressing the evolving landscape of chronic liver disease. Comprehensive strategies that encompass prevention, screening, and treatment of its different etiologies are essential for mitigating its impact and improving patient outcomes.

During the COVID-19 pandemic, various aspects of human life were changed around the world. The present study aimed to provide a systematic review of the available evidence on lived experiences of the COVID-19 pandemic.

This is a systematic review of the meta-synthesis type. Evidence from studies from 2019 to 2021 was used. Keywords of lived experiences, experiences, people, nation, patients, community, COVID-19, corona, and corona disease were searched in PubMed, Science Direct, Web of Science, and Cochrane databases. The Newcastle-Ottawa scale was used to evaluate the quality of articles. A qualitative meta-synthesis was performed by a researcher based on a three-step meta-synthesis method described by Thomas and colleagues. MAXQDA 10 was used for data analysis. The present study is based on the guidelines for Enhancing transparency in reporting the meta-synthesis of qualitative research (ENTREQ). The reliability of this study had a Kappa coefficient of 0.660 with a consistency rate of 98.766%.

Finally, the data from 11 articles were analyzed. The main and sub-themes obtained in this study included negative aspects (chaos, hustle associated, dualities, bad body, value decay, seclusion, psychological challenges) as well as positive aspects (opportunities arising from the individual, family, and social stability).

Problems of life during COVID-19 should be considered as part of the COVID-19 pandemic care program. Individual assessments should normally be considered in a public health crisis. It is recommended to conduct serious, in-depth, and practical research in this field.

All-oral, direct-acting antivirals can cure hepatitis C virus (HCV) in almost all infected individuals; yet, many individuals with chronic HCV are not treated, and the incidence of acute HCV is increasing in some countries, including the United States. Strains on healthcare resources during the COVID-19 pandemic negatively impacted the progress toward the World Health Organization goal to eliminate HCV by 2030, especially among persons who inject drugs (PWID). Here, we present a holistic conceptual framework termed LOTUS (Leveraging Opportunities for Treatment/User Simplicity), designed to integrate the current HCV practice landscape and invigorate HCV treatment programs in the setting of endemic COVID-19: (A) treatment as prevention (especially among PWID), (B) recognition that HCV cure may be achieved with variable adherence with evidence supporting some forgiveness for missed doses, (C) treatment of all persons with active HCV infection (viremic), regardless of acuity, (D) minimal monitoring (MinMon) during treatment, and (E) rapid test and treat (TnT). The objective of this article is to review the current literature supporting each LOTUS petal; identify remaining gaps in knowledge or data; define the remaining barriers facing healthcare providers; and review evidence-based strategies for overcoming key barriers.

Direct-acting antivirals (DAAs) are highly effective for treating HCV infection even among people who inject drugs (PWID). Yet, little is known about patients' adherence patterns and their association with sustained virologic response (SVR) rates. We aimed to summarize various adherence patterns and determine their associations with SVR.

Electronic blister packs were used to measure daily adherence to once-a-day sofosbuvir/velpatasvir during the 12-week treatment period among active PWIDs. Blister pack data were available for 496 participants who initiated DAAs for whom SVR status was known. Adherence was summarized in multiple patterns, such as total adherent days, consecutive missed days, and early discontinuations. Thresholds for adherence patterns associated with >90% SVR rates were also determined.

The overall SVR rate was 92.7%, with a median adherence rate of 75%. All adherence patterns indicating greater adherence were significantly associated with achieving SVR. Participant groups with ≥50% (>42/84) adherent days or <26 consecutive missed days achieved an SVR rate of >90%. Greater total adherent days during 9-12 weeks and no early discontinuation were significantly associated with higher SVR rates only in those with <50% adherence. Participants with first month discontinuation and ≥2 weeks of treatment interruption had low SVR rates, 25% and 85%, respectively. However, greater adherent days were significantly associated with SVR (adjusted odds ratio 1.10; 95% CI 1.04-1.16; p <0.001) even among participants with ≥14 consecutive missed days.

High SVR rates can be achieved in the PWID population despite suboptimal adherence. Encouraging patients to take as much medication as possible, with <2 weeks consecutive missed days and without early discontinuation, was found to be important for achieving SVR.

People who inject drugs can be cured of HCV in >90% of cases, even with relatively low adherence to direct-acting antivirals, but early discontinuations and long treatment interruptions can significantly reduce the likelihood of achieving cure. Clinicians should encourage people who inject drugs who are living with HCV to adhere daily to direct-acting antivirals as consistently as possible, but if any days are interrupted, to continue and complete treatment. These results from the HERO study are important for patients living with HCV, clinicians, experts writing clinical guidelines, and payers.

Hepatitis C is regarded as a global health issue caused by hepatitis C virus (HCV) infection. HCV is targeted for elimination by 2030 as a global public health goal. However, the COVID-19 pandemic has changed human circulation and prevented access to diagnostics and treatment to many other diseases, including hepatitis C. COVID-19 impacted HCV global elimination efforts with implications not fully comprehended yet. The high genetic variability in HCV makes the development of vaccines and pan-genotypic drug therapies a difficult task. Changes in the dynamics of HCV impose new challenges for public health and opportunities for future research. Meta-analysis, the follow up of new cases and sampling of HCV patients compared with previously available data are options for investigating the possible changes. The determination of HCV genotypes and subtypes is important for understanding viral dynamics and treatment; therefore, the changes in genotype and subtype prevalences can directly affect such processes. Recent results in the literature already suggest changes in HCV dynamics during the COVID-19 pandemic, both considering viral circulation and differential genotypic frequencies in distinct geographic areas. In this context, we propose a further examination of these trends using different approaches to provide support for the hypothesis that the COVID-19 pandemic affected HCV circulation, since these findings would have important implications for hepatitis C prevention, treatment and research.

To reach World Health Organization elimination targets for hepatitis C, different strategies are needed to reach people who have not yet been diagnosed and treated. In the context of declining treatment initiation rates, innovation in service design and delivery is necessary: testing and treatment needs to be offered to people in non-traditional settings. The community corrections (probation and parole) population is larger than the prison population, which has high prevalence of hepatitis C and-in some countries-established diagnosis and treatment programs. In this Viewpoint we identify a gap in hepatitis C care for people under community correctional supervision, a group who have either never been imprisoned or need continuity of healthcare provided in prison. We propose that offering hepatitis C screening and treatment would benefit this population, and accelerate progress to hepatitis C elimination.

The top 20 highest burdened countries (in disability-adjusted life years) account for more than 75% of the global burden of viral hepatitis. An effective response in these 20 countries is crucial if global elimination targets are to be achieved. In this update of the Lancet Gastroenterology & Hepatology Commission on accelerating the elimination of viral hepatitis, we convene national experts from each of the top 20 highest burdened countries to provide an update on progress. Although the global burden of diseases is falling, progress towards elimination varies greatly by country. By use of a hepatitis elimination policy index conceived as part of the 2019 Commission, we measure countries' progress towards elimination. Progress in elimination policy has been made in 14 of 20 countries with the highest burden since 2018, with the most substantial gains observed in Bangladesh, India, Indonesia, Japan, and Russia. Most improvements are attributable to the publication of formalised national action plans for the elimination of viral hepatitis, provision of publicly funded screening programmes, and government subsidisation of antiviral treatments. Key themes that emerged from discussion between national commissioners from the highest burdened countries build on the original recommendations to accelerate the global elimination of viral hepatitis. These themes include the need for simplified models of care, improved access to appropriate diagnostics, financing initiatives, and rapid implementation of lessons from the COVID-19 pandemic.

This comprehensive retrospective data-linkage study aimed at evaluating the impact of Direct-Acting Antivirals (DAAs) on Hepatitis C Virus (HCV) testing, treatment trends, and access to care in Tuscany over six years following their introduction. Utilizing administrative healthcare records, our work reveals a substantial increase in HCV tests in 2017, attributed to the decision to provide universal access to treatment. However, despite efforts to eradicate chronic HCV through a government-led plan, the target of treating 6,221 patients annually was not met, and services contracted after 2018, exacerbated by the COVID-19 pandemic. Key findings indicate a higher prevalence of HCV screening among females in the 33-53 age group, influenced by pregnancy-related recommendations, while diagnostic tests and treatment uptake were more common among males. Problematic substance users constituted a significant proportion of those tested and treated, emphasizing their priority in HCV screening. Our paper underscores the need for decentralized HCV models and alternative testing strategies, such as point-of-care assays, especially in populations accessing harm reduction services, communities, and prisons. The study acknowledges limitations in relying solely on administrative records, advocating for improved data access and timely linkages to accurately monitor HCV care cascades and inform regional plans. Despite challenges, the paper demonstrates the value of administrative record linkages in understanding the access to care pathway for hard-to-reach populations. The findings emphasize the importance of the national HCV elimination strategy and the need for enhanced data collection to assess progress accurately, providing insights for future regional and national interventions.

Annually, more than 1.5 million preventable new hepatitis B (HBV) infections continue to occur, with an estimated global burden of 296 million individuals living with chronic hepatitis B infection. This substantial health challenge results in over 820,000 annual deaths being attributed to complications such as liver cirrhosis and hepatocellular carcinoma (HCC). The HBV vaccination remains the cornerstone of public health policy to prevent chronic hepatitis B and its related complications. It serves as a crucial element in the global effort to eliminate HBV, as established by the World Health Organization (WHO), with an ambitious 90% vaccination target by 2030. However, reports on global birth dose coverage reveal substantial variability, with an overall coverage rate of only 46%. This comprehensive review thoroughly examines global trends in HBV vaccination coverage, investigating the profound impact of vaccination on HBV prevalence and its consequences across diverse populations, including both high-risk and general demographics. Additionally, the review addresses the essential formidable challenges and facilitating factors for achieving WHO's HBV vaccination coverage objectives and elimination strategies in the coming decade and beyond.

Achieving hepatitic C virus (HCV) elimination requires linking people who use drugs (PWUD) into care. We report final direct-acting antivirals (DAAs)-based outcomes from the Integrated-Test-stage -Treat (ITTREAT) study. Project ITTREAT (2013-2021), based at an addiction centre, was a 'one-stop' service with innovative linkage to care strategies. Primary outcome was sustained virological response (SVR12) (intention to treat ITT) including whether individuals were recruited in first (period 1) versus last four (period 2 included the COVID-19 pandemic) years of the study. Number recruited were n = 765, mean age 40.9 ± 10.1 years, 78% males, history of current/past injecting drug use (IDU) and alcohol use being 77% and 90%, respectively. Prevalence of a positive HCV PCR was 84% with 19% having cirrhosis. Comparing those recruited in period 2 versus period 1, there was increasing prevalence of IDU, 90% versus 72% (p < .001); homelessness, 67% versus 50% (p < .001); psychiatric diagnosis, 84% versus 50% (p < .001); overdose history 71% versus 31% (p < .001), receiving opioid agonist treatment (OAT) 75% versus 52% (p < .001) and comorbidity 44% versus 25% (p < .001). Of those treated with DAAs (n = 272), ITT SVR rates were 86% (95% CI: 81%-90%), being similar in period 2 versus period 1. Predictors of non-SVR were receiving OAT (OR 0.33, 95% CI: 0.12-0.87, p = .025) and ≥80% adherence (OR 0.01, 95% CI: 0.003-0.041, p < .001). Reinfection rates period 2 versus period 1 (per 100 person-years) were 1.84 versus 1.70, respectively. In the treated cohort, mortality was 15%, being mostly drug-related. Despite increasing complexity of PWUD, high SVR12 rates are achievable with use of OAT and good adherence.

Since the introduction of direct-acting antivirals, thousands of chronic hepatitis C patients have been successfully treated. However, vulnerable populations have a higher prevalence of hepatitis C virus (HCV) infection and face barriers that impede their access to antivirals. We carried out an HCV microelimination program focused on vulnerable population groups in Malaga.

People in drug addiction treatment centers and homeless shelters in Malaga who participated in the program between October 2020 and October 2021 were included. After providing participants with educational information on HCV, a dry drop test (DDT) was used to collect blood for subsequent screening for HCV infection. The participants who were diagnosed with HCV infection were scheduled for comprehensive healthcare assessments, including blood tests, ultrasonography, elastography, and the prescription of antivirals, all conducted in a single hospital visit. Sustained viral response (SVR) was analysed 12 weeks after end of treatment.

Of the 417 persons invited to participate, 271 (65%) agreed to participate in the program. These participants were screened for HCV infection and 28 of them were diagnosed with HCV infection (10%). These hepatitis C-infected patients had a mean age of 53 ± 9 years; 86% were males and 93% were or had been drug users. Among 23 patients with HCV infection, HCV genotype 1a predominated (74%). Medical exams showed that 19% (4/21) had advanced fibrosis (F3-4), and 5% (1/21) had portal hypertension. Finally, 23 infected patients received treatment with glecaprevir/pibrentasvir or sofosbuvir/velpatasvir and SVR was confirmed in 22 patients (96%).

Drug users and homeless people have a higher prevalence of HCV infection than the general population. The microelimination program with educational activity and screening tools achieved a high participation rate, easy healthcare access, and a high rate of SVR despite the SARS-CoV-2 pandemic.

Early neutralizing antibodies against hepatitis C virus (HCV) and CD8 + T cell effector responses can lead to viral clearance. However, these functions alone are not sufficient to protect patients against HCV infection, thus undefined additional antiviral immune mechanisms are required. In recent years, Fc-receptor-dependent antibody effector functions, particularly, antibody-dependent cellular phagocytosis (ADCP) were shown to offer immune protection against several RNA viruses. However, its development and clinical role in patients with HCV infection remain unknown. In this study, we found that patients with chronic GT1a or GT3a HCV infection had significantly higher concentrations of anti-envelope 2 (E2) antibodies, predominantly IgG1 subclass, than patients that cleared the viruses while the latter had antibodies with higher affinities. 97% of the patients with HCV had measurable ADCP of whom patients with chronic disease showed significantly higher ADCP than those who naturally cleared the virus. Epitope mapping studies showed that patients with antibodies that target antigenic domains on the HCV E2 protein that are known to associate with neutralization function are also strongly associated with ADCP, suggesting antibodies with overlapping/dual functions. Correlation studies showed that ADCP significantly correlated with plasma anti-E2 antibody levels and neutralization function regardless of clinical outcome and genotype of infecting virus, while a significant correlation between ADCP and affinity was only evident in patients that cleared the virus. These results suggest ADCP was mostly driven by antibody titer in patients with chronic disease while maintained in clearers due to the quality (affinity) of their anti-E2 antibodies despite having lower antibody titers.

Patients with serious mental illness have a higher risk of hepatitis C virus (HCV) infection but suboptimal HCV care. The current study aimed to facilitate HCV treatment uptake by implementing an integrated outreach care model. Multidisciplinary outreach screening followed by HCV reflex testing and onsite treatment for schizophrenia patients was accomplished through the coordination of nongovernmental organizations, remote specialists, and local care providers. The objective was microelimination effectiveness, defined as the multiplication of the rates of anti-HCV antibodies screening, accurate HCV RNA diagnosis, treatment allocation, treatment completion, and sustained virological response (SVR12; no detectable HCV RNA throughout 12 weeks in the post-treatment follow-up period). A total of 1478 of the 2300 (64.3%) psychiatric patients received HCV mass screening. Seventy-three (4.9%) individuals were seropositive for anti-HCV antibodies. Of the 73 anti-HCV seropositive patients, all (100%) received HCV reflex testing, and 29 (37.7%) patients had HCV viremia. Eight patients (34.8%) had advanced liver disease, including 3 with liver cirrhosis and 2 with newly diagnosed hepatocellular carcinoma. Twenty-three of the 24 (95.8%) patients who stayed in the healthcare system received and completed 8 weeks of glecaprevir/pibrentasvir treatment and post-treatment follow-up without significant DDIs or adverse events. The SVR12 rate was 100%. The microelimination effectiveness in the current study was 61.6%. Individuals with serious mental illness are underserved and suffer from diagnostic delays. This patient-centered and integrated outreach program facilitated HCV care in this marginalized population.

Information concerning the impact of the COVID-19 health crisis on populations most affected by HIV and hepatitis C virus (HCV; or key populations [KP]), and those working with these populations in community settings, is limited. Community-based organizations working in the field of HIV and viral hepatitis are well placed to identify and meet the new needs of KP owing to the health crisis.

This study aims to describe the development and implementation of an exploratory and descriptive multicountry, community-based research program, EPIC (Enquêtes Pour évaluer l'Impact de la crise sanitaire covid en milieu Communautaire), within an international network of community-based organizations involved in the response to HIV and viral hepatitis. The EPIC program aimed to study the impact of the COVID-19 health crisis on KP or people living with HIV or HCV and people working with these populations at the community level (community health workers [CHWs]) and to identify the key innovations and adaptations in HIV and HCV services.

A general protocol and study documents were developed and shared within the Coalition PLUS network. The protocol had a built-in flexibility that allowed participating organizations to adapt the study to local needs in terms of the target population and specific themes of interest. Data were collected using surveys or interviews.

From July 2020 to May 2022, a total of 79 organizations participated in the EPIC program. Across 32 countries, 118 studies were conducted: 66 quantitative (n=12,060 among KP or people living with HIV or people living with HCV and n=811 among CHWs) and 52 qualitative (n=766 among KP or people living with HIV or people living with HCV and n=136 among CHWs).

The results of the EPIC program will provide data to describe the impact of the health crisis on KP and CHWs and identify their emerging needs. Documentation of innovative solutions that were put into place in this context may help improve the provision of services after COVID-19 and for future health crises.
