Patients with acquired immunocompromising conditions face considerable risk of developing herpes zoster (HZ). Based on the underlying medical conditions and degree of immune dysfunction, these patients require tailored strategies for HZ prevention. In Hong Kong, there is currently a lack of guidelines addressing the unique needs of this vulnerable population, including the use of prophylactic measures such as antivirals and vaccines. An expert panel comprising clinical immunologists, nephrologists, infectious diseases specialists, rheumatologists, hematologists and oncologists in Hong Kong met to review current literature and international guidelines to propose a locally adapted decision-making framework for HZ prophylaxis, in patients with acquired immunocompromised conditions. This article summarizes the consensus and presents a guiding criteria for clinicians to navigate the complexities associated with HZ prevention, in the context of acquired immunodeficiency.

This work aims to illustrate the evolution and ongoing challenges of rheumatoid arthritis (RA) management with targeted therapy over 20 years, using a cohort study from the world's oldest society.

Data were obtained from FIRST registry, a multicenter cohort of patients with RA treated with biologic/targeted synthetic disease-modifying antirheumatic drugs (b/tsDMARDs). Patients were followed for 60 months and assessed for drug efficacy, retention, and reasons for discontinuation.

Analysis of 5130 treatments over 16,616 person-years revealed shifts in strategies and demographics. Despite an aging population (51.9-64.3 years) with increasing comorbidities (lung disease: 11.1-36.2%, malignancy: 2.2-13.1%), b/tsDMARD use expanded to include patients with lower disease activity. With better disease control, discontinuations due to adverse events decreased, and particularly infections fell from 2.1 to 0.7 per 100 person-years. Remission rates improved over time in the naïve group but remained largely unchanged in the prior b/tsDMARDs group. Retention rates varied by bDMARD class, with TNF inhibitors (TNFi) showing a decrease over time and IL-6 receptor inhibitors (IL-6Ri) and CTLA4-Ig showing an increase in retention. TNFi had high remission rates but low retention, whereas CTLA4-Ig and IL-6Ri had lower remission rates and higher retention. Changes in functional improvement were modest overall, and in patients aged 75 years and older, functional gains remained limited.

The study highlights the evolving landscape of RA management in an aging society, noting gains in efficacy and safety. However, unmet needs persist, particularly for patients not fully achieving treat-to-target goals and those with limited functional improvement.

To identify the factors that inhibit human papilloma virus (HPV) vaccination to improve the high HPV infection rate and cervical cancer incidence among SLE patients.

We conducted a questionnaire survey of female SLE patients aged 18-45 years attending our hospital to analyze factors related to HPV vaccination.

We obtained responses of 88 participants. Only 5 (5.7%) were received HPV vaccination, 15 (17.0%) were uncertain of their vaccine history, and 27 (30.7%) had never even heard of HPV vaccination. The reasons for unvaccinated against HPV were "don't know" with 24 participants, "missed opportunity" with 15, and "troublesome, somehow" with 8. The most trusted source of medical information for the unvaccinated was their physician (69, 60.2%). Among the unvaccinated, those who wished to be vaccinated in the future were positively correlated with "trust of vaccine benefit" (r = 0.561, p = 0.005) and "general knowledge about HPV vaccine" (r = 0.512, p = 0.013), and negatively correlated with "negative attitudes toward vaccination and vaccine policy" (r = -0.547, p = 0.007).

HPV vaccination rate among SLE patients in Japan was extremely low. The main reason was lack of knowledge. The most effective solution is considered to provide accurate information and adequate recommendations of HPV vaccination by attending physicians.

This article presents the study protocol of a retrospective cohort study designed to compare the effectiveness of herpes zoster, and influenza vaccines in individuals with multiple sclerosis (MS), chronic inflammatory bowel diseases (IBD), or chronic inflammatory rheumatic diseases (CIRD) to individuals without these diseases, using claims data of one of the largest population based health insurances in Germany.

Individuals with autoimmune diseases such as MS, IBD, and CIRD are more susceptible to vaccine preventable infectious diseases such as influenza and herpes zoster, due to the autoimmune disease itself, the presence of comorbidities and immunosuppressive therapies. Vaccines are the primary means to prevent such diseases. The efficacy of these vaccines is usually estimated using large randomized controlled trials, from which patients with MS, IBD, and CIRD are often excluded. It is therefore unclear whether these vaccines are also effective for these patients.

A target trial emulation based on observational claims data of a statutory health insurance company is proposed.

This study will aim to emulate multiple target trials to compare the effectiveness of herpes zoster and influenza vaccines in patients with and without MS, IBD and CIRD using data from a large German statutory health insurance provider (BARMER). The primary outcome for each vaccine effectiveness analysis is the disease itself. The analysis will be carried out using both time-dependent matching and a multivariable Cox proportional hazards model in conjunction with g-computation. Additionally, the moderating effect of immunosuppressive therapies on the vaccine effectiveness will be estimated using a stratified secondary analysis.

This study will estimate and compare the effectiveness of influenza and herpes zoster vaccines in individuals with and without MS, IBD, and CIRD. Because of the large amount of data, this study will also be able to investigate the role of the immunosuppressive medication on vaccine effectiveness, which may provide guidance for vaccine administration guidelines.

Systemic lupus erythematosus (SLE) is a complex autoimmune disease characterized by immune dysregulation and autoantibody production. Despite advances in treatment, achieving sustained disease control remains challenging. Rituximab (RTX) and belimumab (BELI) are two B-cell-targeting biologics with complementary mechanisms of action, leading to increasing interest in their combination as a therapeutic strategy for refractory SLE. RTX depletes CD20+ B cells, whereas BELI inhibits B-lymphocyte stimulator (BLyS), reducing the survival of autoreactive B cells. Sequential therapy with these agents may mitigate B-cell repopulation and improve disease control. Recent studies, including SynBioSe and BEAT-LUPUS, suggest that RTX-BELI therapy can reduce autoantibody levels, neutrophil extracellular trap formation, and disease activity, with many patients achieving a lupus low disease activity state (LLDAS). However, the BLISS-BELIEVE and CALIBRATE trials did not demonstrate superiority over monotherapy, highlighting the need to refine patient selection. Combination therapy may be particularly beneficial in lupus nephritis, where BELI delays autoreactive B-cell reconstitution following RTX, potentially prolonging remission. While RTX-BELI therapy is generally well-tolerated, some studies report increased infections, necessitating careful patient monitoring. Lessons from other immune-mediated diseases, including inflammatory bowel disease and rheumatoid arthritis, underscore the potential benefits and risks of dual biologic therapy. Further research, including the ongoing SynBioSe-2 trial, is needed to clarify the optimal use, sequencing, and safety profile of RTX-BELI in SLE. Identifying biomarkers predictive of response may enable personalized treatment approaches, ultimately improving long-term outcomes for patients with refractory SLE.

Rheumatoid arthritis (RA) is a chronic autoimmune condition disproportionately affecting older adults (> 60 years), who often experience increased disease severity and comorbidities, including cancer. A comprehensive review of the literature was conducted, examining the prevalence of malignancy in patients with RA, associated risk factors, and treatment challenges, including management considerations such as psychological distress and lifestyle modifications. Clinical guidelines and consensus statements were summarized to provide practical insights for optimizing care. Older adults with RA are at an elevated risk for developing cancer due to chronic inflammation, immunosenescence from aging, and shared risk factors such as smoking. Patients with RA tend to have poorer cancer survival rates than individuals without RA, particularly for lung cancer and lymphoma. Immunosuppressive therapies used to treat RA may modestly increase cancer risks but are critical for disease control. Current guidelines emphasize discontinuation or adjustment of RA therapies upon cancer diagnosis, with tailored approaches based on cancer type and stage. Non-pharmacologic interventions, including lifestyle modifications and psychological support, play a vital role in improving quality of life and mitigating disease flares during cancer treatment. The management of RA in older adults with a history of cancer requires a personalized, multidisciplinary approach that balances the need for RA symptom control without affecting cancer outcomes. Shared decision-making, incorporating patient preferences and comorbidities, is critical for optimizing care. Further research is needed to strengthen evidence-based guidelines for this population and address gaps in understanding treatment safety and efficacy.

Current guidelines recommend pneumococcal vaccination in individuals who are over the age of 65 or are immunosuppressed due to a disease or treatment. The objective of this study was to assess vaccine uptake rates in people with inflammatory arthritis for the pneumococcal, influenza and Covid-19 vaccines and factors determining uptake.

We conducted a retrospective single centre cohort study in the UK of individuals with rheumatoid arthritis, psoriatic arthritis and axial spondyloarthritis between October and December 2023. Data were collected for age, gender, co-morbidities, immunosuppressive therapies and dates of vaccines. Logistic regression was used to evaluate predictors of vaccine uptake, with adjustments for demographic and clinical factors.

Nine hundred and six individuals were identified; 46% were receiving treatment with conventional synthetic DMARD (csDMARD), 26% were on biologic monotherapy, and 23% were on both biologic and csDMARDs. Three hundred and sixteen individuals (35%) received a pneumococcal vaccine, lower than uptake for influenza (63%) and Covid-19 (87%) vaccines. Predictors of pneumococcal vaccine uptake included age, with older patients more likely to be vaccinated (odds ratio [OR] for age ≥ 65 years: 1.67; 95% CI: 1.21, 2.29). Those on biologic therapy demonstrated higher likelihood of vaccination (OR for biologic therapy: 1.81; 95% CI: 1.33, 2.47). Additional Joint Committee on Vaccination and Immunisation Green Book indicators also positively influenced vaccine uptake (OR: 1.67; 95% CI: 1.19, 2.33).

Pneumococcal vaccine uptake in inflammatory rheumatic diseases is low, especially in younger patients and those not on biologic therapy. The study highlights the need for a focused approach, distinct from strategies for other vaccines, to address this public health challenge.

Patients with immune-mediated rheumatic diseases (IMRDs) face an elevated risk of varicella-zoster virus infection (VZV) and herpes zoster (HZ). Treatment with immunosuppressors further increases the risk. A new recently approved adjuvant recombinant inactive vaccine offers safe protection against HZ. However, limited data exist on the efficacy of this new vaccine in patients with IMRDs treated with JAK inhibitors (JAK-i). We aimed to characterize B- and T-cell immune responses elicited by the HZ recombinant subunit vaccine in patients with IMRDs under treatment with JAK-i, and to identify factors that might be associated with reduced immunogenicity, and therefore reduced protection.

We investigated humoral and cellular CD4 and CD8 immune responses following a two-dose regimen of the recombinant inactive vaccine in 43 patients with rheumatic diseases treated with different JAK-i. The responses were compared with age, gender and disease-matched healthy controls.

Patients with IMRDs treated with JAK-i showed reduced seroconversion rate (63% vs. 100% and lower VZV IgG titres (1222 ± 411 vs. 3048 ± 556, P < 0.0001) as compared with healthy controls. Functional T CD4 (IL-2 plus IFN-γ secretion) and T CD8 (granzyme A and/or granzyme B secretion) immune responses were also significantly diminished in IMRD patients. Negative correlation was found between VZV antibody titres and age, specific treatments (baricitinib, tofacitinib, upadacitinib), cumulative MTX and glucocorticoid doses, history of multiple DMARDs and treatment duration with JAK-i. Functional T-CD4 responses but not functional T-CD8 responses also showed similar negative correlations. Positive associations were observed between functional T-CD4 and T-CD8 responses.

Our study provides valuable insights into the immune responses elicited by the recombinant inactive vaccine in patients with IMRDs treated with JAK-i. In these patients we have observed a broad impact on the adaptive humoral and cellular immune responses, suggesting a potential reduction in protection against HZ infection and VZV reactivation.

The objectives of this study were to evaluate the effectiveness of short message service (SMS) and/or email reminders in improving influenza vaccination coverage rates among RA patients treated with anti-TNF therapies, and to identify factors associated with vaccination.

This study was a nested randomized controlled trial in the ART e-cohort, an ongoing French nationwide multicentre prospective cohort of RA patients treated with anti-TNF therapy. Patients were 1:1 randomized, with stratification on age. The intervention consisted of regular reminders via SMS and/or emails to get vaccinated against influenza during the vaccination campaign. At the end, all participants received a questionnaire. The primary outcome was influenza vaccination coverage. Secondary outcomes included the vaccination coverage before and after the COVID-19 pandemic, and factors associated with vaccination.

Between October 2021 and April 2022, 446 participants were randomized (224 to the intervention group and 222 to the control group). Among them, 325 (73%) reported their vaccination status and 221 (68%) were vaccinated against influenza: 116/158 (73%) in the intervention group, vs 105/167 (63%) in the control group (relative risk 1.08; 95% CI 0.95-1.23). The vaccination coverage before and after the COVID-19 pandemic did not differ (72% vs 72%; 95% CI -8% to 8%). Age ≥65 years [odds ratio (OR) 6.25; 95% CI 2.88-13.60] and previous influenza vaccination in the years before inclusion (OR 7.81; 95% CI 4.36-14.02) were associated with higher rates of vaccination.

SMS and/or e-mail reminders did not significantly improve influenza vaccination rates in our cohort. The COVID-19 pandemic did not substantially impact the influenza vaccination coverage. Our results might be counterbalanced by an already high vaccination coverage.

In light of the introduction of new Janus kinase inhibitors (JAKi), new indications for JAKi and recent safety considerations that have arisen since the preceding consensus statement on JAKi therapy, a multidisciplinary taskforce was assembled, encompassing patients, health care professionals, and clinicians with expertise in JAKi therapy across specialties. This taskforce, informed by two comprehensive systematic literature reviews, undertook the objective to update the previous expert consensus for using JAKi developed in 2019. The taskforce deliberated on overarching principles, indications, dosage and comedication strategies, warnings and contraindications, screening protocols, monitoring recommendations, and adverse effect profiles. The methodology was based on the European Alliance of Associations for Rheumatology standard operating procedures, with voting on these important elements. Furthermore, an updated research agenda was proposed. The task force did not address when a JAKi should be prescribed but rather considerations once this decision has been made. This update aimed to equip clinicians with the necessary knowledge and guidance for the efficient and safe administration of this expanding and significant class of drugs.

This study evaluates assessment and prescription trends in systemic sclerosis across different Indian healthcare settings, with a focus on diagnostic practices such as screening for interstitial lung disease, pulmonary hypertension, and adherence to recommended treatment protocols. The goal is to identify disparities and areas for improvement in the management of systemic sclerosis.

A cross-sectional questionnaire-based survey was conducted among rheumatologists from teaching and non-teaching hospitals across India. Data collection focused on key diagnostic practices such as the modified Rodnan skin score, chest imaging, pulmonary function tests, and echocardiography. Organ-specific prescription trends were collected and compared between teaching and non-teaching centres.

The response rate for the survey was 70.5%. Teaching centres demonstrated higher adherence to performing modified Rodnan skin score at baseline (72.2%) compared to non-teaching hospitals (38.4%). For interstitial lung disease screening, overall, 93.7% performed chest imaging, with only 31.4% utilizing a High-Resolution CT thorax as the screening tool. Teaching centres performed 6MWT (79.5%) more often than non-teaching centres (64.7%). Echocardiography was commonly used for screening pulmonary hypertension (96.4%), while 16.5% reported using right heart catheterization. Steroids were used by 79.9% of participants at low doses (<10 mg) for a duration of less than 3 months, commonly for myositis(68%). Methotrexate(49.8%) and mycophenolate (38.3%) were the most prescribed first-line agents for systemic sclerosis-skin involvement. For systemic sclerosis-interstitial lung disease, mycophenolate (95%) was the most commonly used immunosuppression. Sequential addition of antifibrotic(62.4%) to immunosuppression was preferred over an upfront combination in systemic sclerosis-interstitial lung disease. The majority treated uncomplicated Raynaud's phenomenon with calcium channel blockers, followed by PDE5 inhibitors (61.4%). An upfront combination of endothelin receptor antagonists and PDE5i for systemic sclerosis-pulmonary hypertension was reported by 42.2%.

The study highlights differences in systemic sclerosis management trends among Indian rheumatologists. Despite variations in disease-encounter and practice settings, adherence to international recommendations in key domains and areas for further improvement are brought to light.

Atopic dermatitis (AD) is a chronic inflammatory skin disorder significantly affecting quality of life and healthcare resources. Upadacitinib has been recently approved for ad treatment in Australia and offers a promising alternative to traditional systemic therapies. However, real-world data on their long-term effectiveness, particularly drug survival (the time from treatment initiation to discontinuation), remain scarce. This study aims to investigate the drug survival rate and factors affecting the drug survival of Upadacitinib in ad patients.

In this retrospective analysis, we included 21 adults with moderate to severe AD from the Royal Melbourne Hospital electronic medical records. Drug survival rates were analysed using Kaplan-Meier survival estimates, reasons for discontinuation were examined, and cox-proportional analysis was utilised to investigate factors affecting drug survival.

Upadacitinib demonstrated a high treatment retention rate, with a survival probability of 90.5% by the end of the 4-week mark. Reasons for discontinuation included factors affecting drug survival, concurrent infections, side effects, and loss of efficacy.

These findings indicate that Upadacitinib may offer a longer-lasting treatment option with good overall retention in ad management. Real-world data such as these provide crucial insights for dermatologists in choosing appropriate therapies, potentially enhancing patient satisfaction, adherence, and long-term outcomes. Further studies with larger sample sizes and diverse populations are recommended to validate these findings and guide treatment strategies.

ObjectiveTo evaluate and summarize the best evidence on self-management in adult patients with systemic lupus erythematosus (SLE) and provide evidence-based recommendations in clinical settings.MethodsLiteratures related to self-management of SLE patients were searched in the guideline websites, professional association websites and relevant databases, including clinical decisions, guidelines, expert consensus, best practice recommendations, evidence summaries, meta-analyses, systematic reviews and randomized controlled trials, etc. The search time was from January 2018 to September 2023.ResultsA total of 19 literatures were included, consisting of 9 guidelines, 4 expert consensus, 4 clinical decisions, and 2 systematic reviews, and 49 pieces of evidence were extracted. After sorting and discussing, the evidence were integrated into six aspects: skin management, diet management, exercise management, vaccination management, complication management, as well as follow-up and lifestyle management.ConclusionThe best evidence of self-management in SLE patients summarized in this study is of high quality, which can provide evidence-based recommendations for clinical medical staff and patients, so as to help self-management of SLE patients in a more scientific and effective way.

Biologic and targeted-synthetic disease-modifying antirheumatic drugs (b/tsDMARDs), are pivotal in the management of autoimmune-inflammatory disorders, acting by suppressing pathological immune activation. Because of associated immune dysfunction, opportunistic or serious infections (SIs), and latent disease reactivation is frequently reported. This study aimed to investigate the epidemiology, risk factors, and outcomes of SIs in patients treated with b/tsDMARDs in Qatar.

A retrospective cohort study was conducted at Hamad Medical Corporation, including all the patients treated with one of 10 b/tsDMARDs, between January 2017 and July 2021. Besides descriptive statistics, the Chi-square test and Kaplan-Meyer survival analysis were used for statistical analysis.

Out of 1092 patients, 86 (7.9%) had SIs, with an incidence rate of 39.4 per 1000 patient years. Mean duration of onset was 10.8 months post-initiation of therapy. Younger age groups (18-52 years) were predominantly affected. A significant association was observed between the primary diagnosis (rheumatological followed by gastrointestinal, neurological, and dermatological disorders) and the occurrence of SIs (χ² = 9.512, p < 0.050). Adalimumab and infliximab had a higher risk of SIs compared to other b/tsDMARDs. There was no significant difference between TNF-inhibitors and others. Ocrelizumab was significantly associated with incidence of COVID-19 SIs (χ² = 16.84, p = 0.0000408), and etanercept with Staphylococcus aureus SIs (χ² = 17.51, p = 0.0000285). Predominant infection sites were skin-soft tissue and respiratory tract. Most of the SIs were secondary to either bacteria (43%) or viruses (17.4%). The mean duration of hospitalization was 9 days, and 7% of patients required critical care, with no recorded 90-day mortality.

Patients with inflammatory conditions managed with b/tsDMARDs are at significant risk of SIs, which necessitate appropriate patient selection weighing benefits and risks, as well as careful long-term management that include patient education and relevant preventive therapy.

We aimed to evaluate the content and quality of websites for consumers providing information about human papillomavirus (HPV) risks in patients with systemic lupus erythematosus (SLE).

We conducted an environmental scan of websites for patients and the general public with information about HPV and SLE. We searched Google from inception to June 2023, using the terms "HPV" and "lupus". We included websites with information about HPV and SLE. Two reviewers appraised the websites and collected website characteristics, and rated various attributes: completeness and comprehensiveness, accuracy, technical elements, design and aesthetics, usability, readability, and accessibility.

We identified 16 websites for analysis. Ten (62.5 %) were commercial websites One website provided complete and comprehensive information about HPV risk, screening, and vaccination in patients with SLE; 7 (44 %) websites provided only information about the HPV vaccine. Eight websites included risk of HPV infection, cervical cancer screening, and cervical cancer risk in patients with SLE. Seventy-five percent provided information based on clinical guidelines, textbooks, peer-reviewed papers or scientific publications while the remaining were based on expert opinions. All websites were considered to have adequate design and aesthetics and were easy to navigate. Only 1 (6 %) website had a 6th-grade reading level and the other had reading levels higher than that (not appropriate for consumer websites). The overall quality scores ranged from 32 to 51 (maximum 69).

Our findings showed that most websites for patients and the general public with information about HPV and SLE did not provide complete and comprehensive information about HPV.

Chronic inflammation is a pivotal driver in the progression of atherosclerosis, significantly contributing to the burden of cardiovascular disease (CVD). Patients with chronic inflammatory diseases, such as inflammatory bowel diseases (IBDs) (e.g., ulcerative colitis and Crohn's disease), rheumatological disorders, as well as individuals with auto-immune diseases (such as systemic lupus erythematosus), present a higher risk of major adverse cardiac events (MACEs). Despite their elevated CVD risk, these populations remain underrepresented in cardiovascular research, leading to a critical underestimation of their cardiovascular risk (CVR) in clinical practice. Furthermore, even recent CVR scores poorly predict the risk of events in these specific populations. This narrative review examines the physiopathological mechanisms linking chronic inflammation, immunomodulation, atherosclerosis, thrombosis and cardiovascular events. We review data from epidemiological studies and clinical trials to explore the potential cardiovascular benefits of anti-inflammatory and immunomodulatory therapies. Despite existing evidence, significant gaps in knowledge remain. Future research is mandatory, focusing on innovative strategies for risk stratification and optimization, including lipidomics, proteomics, advanced inflammatory markers, microbiota profiling, and cardiovascular imaging. Addressing these unmet needs will enhance understanding of cardiovascular risk in chronic inflammatory diseases, enabling tailored interventions and better outcomes.

B-cell depletion therapy is employed in a variety of clinical contexts from auto-immune diseases to malignancy. Prior research on patients with prior B-cell depletion treatment has suggested a mortality risk in patients hospitalized with COVID-19 however previous case-control studies have differed in their methods of patient comparison. Patients previously treated with B-cell-depletion hospitalized with COVID-19 were compared to matched controls in the Johns Hopkins Health System between March 1, 2020 and November 30, 2021. The primary outcome was 30-day all-cause mortality. Secondary outcomes included time to severe illness or death and time to clinical improvement. To eliminate bias due to imbalanced covariates, each patient who had previously received B-cell depletion therapy was matched with patients who had not received therapy based on age, sex, race, WHO severity score, admission date, COVID-19 specific treatment, and vaccination status. Propensity scores were calculated from a multivariable logistic regression model and performed on the matched sets, using B-cell depletion as the outcome, where the propensity score was the probability of receiving B-cell depletion therapy. The propensity score included matched covariates as well as smoking status, medical comorbidities, and vaccination status. Cox proportional-hazards regression models were applied on the matched sets to perform time to death, time to severe illness or death, and time to clinical improvement analyses. 50 patients were identified who had received B-cell depletion therapy and were compared to 186 matched controls. Patients treated with B-cell depletion experienced 30-day mortality of 6.0% compared to 3.8% in controls, adjusted hazard ratio (aHR) 1.45 (95% CI 0.30 to 6.95). B-cell-depleted patients experienced a longer time to clinical improvement, aHR 0.65 (95% CI 0.45-0.94). In this cohort, patients treated with B-cell depletion experienced a higher mortality rate compared to matched controls however this was not statistically significant. This group also experienced a prolonged time to clinical improvement based on WHO severity score.

This study aims to assess the impact of recombinant zoster vaccine (RZV) on the risk of major cardiovascular events (MACE) in patients with rheumatoid arthritis (RA), spondyloarthritis (SpA), or psoriatic diseases who are receiving Janus kinase inhibitors (JAKi). We conducted a new user design study utilizing the TriNetX database. We identified patients diagnosed with RA, SpA, or psoriatic diseases receiving JAKi. Two cohorts were constructed based on RZV vaccination status. Propensity score matching was performed. The primary outcome was MACE, analyzed using Cox regression with hazard ratios (HR) and Kaplan-Meier plots. Subgroup analyses were performed by age, sex, race, and zoster history. Sensitivity analyses were conducted with different follow-up periods and diseases. Of the 1 528 771 eligible patients initially included, each cohort included 1756 patients after propensity score matching. No significant difference in MACE risk was observed between the two cohorts (HR 1.121, 95% CI: 0.901-1.395). Subgroup and sensitivity analyses were consistent with the main findings. However, RZV vaccination was associated with a significant reduction in all-cause mortality (HR 0.610, 95% CI: 0.427-0.870). Subgroup analyses indicated that the mortality benefit was particularly evident in females (HR 0.585, 95% CI: 0.379-0.901) and those aged 65 years and older (HR 0.500, 95% CI: 0.301-0.806). In patients with immune-mediated inflammatory diseases receiving JAKi, RZV vaccination is associated with a 39% reduction in all-cause mortality compared to unvaccinated individuals. RZV vaccination should be considered for this high-risk population.

By the end of the nineties, new immunomodulatory options impacting on the determinants of many immune-mediated diseases became available. These drugs were also called biologicals. Their use was associated with a significant improvement in the management of the patients and on their clinical evolution over time. On the other hand, their use was found to be also associated with an over-risk of infectious complications, in particular of viral origin, even though the savings of other at-risk treatments (e.g. corticosteroids or cyclophosphamide) allowed by these new therapies could have contributed to reduce it. These viral infections may be linked to an increased susceptibility to new infections because of impaired immunity and/or lower responsiveness to vaccination, to a higher risk of reactivation of latent infections, and to a higher severity than observed in the general population. Viruses mostly involved are respiratory (influenza, RSV, and SARS-CoV2), Varicella-Zoster, hepatitis B, or JC viruses, in particular. The viral risk depends not only on the type of biologicals, but also on the underlying disease, the associated comorbidities, the associated treatments, the epidemiological environment, and the individual and collective immunity. At an individual level, prevention and management of the infectious risk are of utmost importance in the global management of patients on biologicals.

Rheumatoid arthritis (RA) is a chronic inflammatory disorder that can affect women of reproductive age. In recent decades, significant advances have been made in the development of new medications, including biologic disease-modifying anti-rheumatic drugs (DMARDs) and Janus kinase (JAK) inhibitors. Women with RA are prone to infertility, with 42% experiencing a time to pregnancy exceeding 12 months. High disease activity, as well as the use of high-dose glucocorticoids and Non-Steroidal Anti-Inflammatory Drugs (NSAIDs), are associated with infertility and adverse pregnancy outcomes. Additionally, some medications, such as methotrexate, are linked to teratogenicity, highlighting the importance of providing preconception care in everyday practice. Recent advancements in reproductive care have improved our ability to manage RA during pregnancy, leading to better pregnancy outcomes. In this review, we summarize key aspects of fertility care, pregnancy and lactation management, including medication strategies, neonatal vaccination, and long-term outcomes for offspring born to mothers with RA.

Rheumatology patients on biological disease-modifying anti-rheumatic drugs (bDMARDs) have been proposed to be at a higher risk of infections. Our review summarizes the current evidence behind this theory as well as explores which factors predispose patients to various infections, which agents are more likely to cause infections, and which infections are common in these patients. We also aim to explore updated guidelines on infection prevention in patients on bDMARDs.

Human papillomavirus (HPV) infections cause cancer of the cervix, vagina, vulva, anus, penis and upper respiratory tract. The prevention of HPV-induced cancers is a public health issue. Patients with systemic lupus are at increased risk of persistent HPV infection and cervical cancer due to treatment-induced immunosuppression. HPV vaccination and screening for precancerous lesions are two effective means of preventing cervical cancer. Despite the demonstrated safety and efficacy of the HPV vaccine, coverage of HPV vaccination in SLE adults remains low. Screening for cervical cancer is only carried out as recommended in one lupus patient in two. Catch-up HPV vaccination, therapeutic vaccination and vaginal self-sampling are innovative prevention strategies adapted to patients at risk of HPV-induced cancer.

Measures to prevent HPV-induced cancers are insufficiently implemented in patients managed for systemic lupus. Healthcare professionals and patients need to be made aware of the importance of HPV preventing vaccination.

Musculoskeletal disorders are a significant public health burden concern, projected to increase in the coming decades, and will substantially contribute to the rising prevalence of functional impairment, frailty and disability in a growing global population. Since persons with musculoskeletal disorders tend to have immune dysfunction, inflammation or be taking immunosuppressive medication, prevention of vaccine-preventable diseases (VPDs) in this group is particularly important. The European Interdisciplinary Council for Aging (EICA) and the European Society for Clinical and Economic Aspects of Osteoporosis, Osteoarthritis and Musculoskeletal Diseases (ESCEO) jointly convened a 2-day in-person and virtual meeting on 26-27 September 2023, to review the state of the evidence on the link between musculoskeletal diseases, infections and vaccines. We present here the Executive Summary of the proceedings of this meeting. We review the importance of physical activity in preventing or mitigating both musculoskeletal diseases and risk of infection. We summarize current knowledge of the impact of common VPDs on the development and progression of musculoskeletal diseases, and the role of selected vaccines in preventing onset and worsening of frailty and disability in these individuals. This report summarizes the evidence presented at the two-day meeting, highlighting the need to raise awareness among scientists, healthcare professionals, decision-makers, civil society and the general public about the long-term sequelae of VPDs, with focus on the health status of older patients with musculoskeletal diseases.

Background: The aim of this study was to evaluate the serological response after the complete hepatitis B vaccination of patients according to the immunosuppressive treatment they underwent, and to identify potential factors associated with non-responders. Methods: A prospective cohort study was conducted, and patients under immunosuppressive therapies were considered exposed. The main outcome was non-response to hepatitis B vaccination. Bivariate analysis was conducted to detect differences between exposed and non-exposed patients. A multivariable log-binomial regression model was designed to analyze potential factors independently associated with non-responders. Results: A total of 289 patients were included. Immunosuppressive treatment was associated with non-response to hepatitis B vaccination (RR = 2.49, 95% CI: 1.26-4.96). Concretely, the use of cytotoxic therapies showed increased risk, although anti-CD20 and anti-JAK also showed a tendency to be associated with non-responders. Other variables associated with non-responders were older age (6-7% higher risk per year), smoking (RR = 3.08, 95% CI: 1.41-6.74) and certain vaccine regimens. These findings were similar for persistent non-responders despite an additional booster dose. Conclusions: Patients receiving immunosuppressive treatments, who are older in age or who are smokers have a higher risk of non-response to conventional hepatitis B vaccination. These data might serve to optimize hepatitis B vaccination in high-risk patients.

To provide a comprehensive overview of peripheral spondyloarthritis (pSpA), focusing specifically on its occurrence and management in patients with inflammatory bowel disease (IBD).

An exhaustive literature search was conducted in PubMed, Embase, Cochrane Database of Systematic Reviews, and Google Scholar to identify relevant studies on pSpA in IBD patients. Titles, abstracts, and full-text articles were screened for relevance. Data on study design, patient characteristics, diagnostic criteria, main findings, and conclusions were extracted from selected articles. Study quality was assessed using appropriate checklists. Information was synthesized narratively to summarize current understanding.

pSpA is the most common extraintestinal manifestation of IBD, with a median prevalence of 16%. It worsens quality of life and requires collaboration between gastroenterologists and rheumatologists for optimal diagnosis and treatment. Several "red flags" guide appropriate specialist referral of IBD patients with suspected pSpA. Once the diagnosis is confirmed, the choice of therapy depends on IBD phenotype and patterns of articular/axial involvement. Anti-tumor necrosis factor (TNF) drugs are first-line biologics, with interleukin (IL)-12/23 and IL-23 inhibitors as alternatives for anti-TNF failure. Small molecules like apremilast and Janus kinase inhibitors also have utility. Recommended treatment algorithms exist, but more randomized controlled trials are needed.

Early identification of pSpA is crucial in IBD patients to enable timely intervention, prevent structural damage, and minimize disability. A multidisciplinary, holistic approach addressing musculoskeletal and extra-musculoskeletal manifestations is key to optimal patient outcomes.

Parvovirus B19 (B19V) is a human pathogen from the Parvoviridae family that primarily targets and replicates in erythroid progenitor cells (EPCs). While its symptoms are typically self-limiting in healthy individuals, B19V can cause or exacerbate autoimmune diseases in vulnerable patients. This review integrates the involvement of B19V in the development and worsening of several autoimmune diseases, including systemic lupus erythematosus (SLE), rheumatoid arthritis (RA), juvenile idiopathic arthritis (JIA), hematological disorders (thalassemia, anemia, and thrombocytopenia), vasculitis, antiphospholipid syndrome (APS), dermatological disease (systemic sclerosis, psoriasis), autoimmune thyroid disease, myocarditis, and myasthenia gravis, and autoinflammatory disease of adult-onset Still's disease (AOSD). B19V contributes to autoimmunity and autoimmune disease onset and progression through mechanisms such as molecular mimicry, immune system disruption, and chronic infection. By summarizing findings from in vitro experiments, clinical case studies, seroprevalence data, and biopsy results, this review highlights the critical connection between B19V and autoimmune disease development. Recognizing the role of B19V in the early diagnosis and management of these conditions is essential, as its presence may influence the disease course and severity. Greater awareness among healthcare professionals and the public is necessary to address the impact of B19V, leading to more accurate diagnoses and better-informed treatment approaches for autoimmune diseases linked to the virus.

The purpose of this review is to outline considerations for treating older adults with rheumatoid arthritis-associated interstitial lung disease (RA-ILD) as it relates to infection, comorbidities, cancer, and quality of life.

The recent 2023 American College of Rheumatology/American College of Chest Physicians guideline conditionally recommended specific disease-modifying antirheumatic drugs (DMARDs), antifibrotics, and short-term glucocorticoids to treat RA-ILD. Since RA-ILD often affects older adults, we contextualize these pharmacologic options related to infection, gastrointestinal (GI) effects, cancer, cardiovascular disease, and quality of life. Nearly all DMARDs and glucocorticoids are immunosuppressive and increase infection risk. Rituximab, mycophenolate, cyclophosphamide, and glucocorticoids may have particularly high infection risk. Many therapies recommended for treating RA-ILD have potential GI side effects. Antifibrotics have a high rate of nausea and diarrhea. Janus kinase inhibitors may increase risk of cancer and cardiovascular disease in older people. In older individuals, decisions must weigh the risks and benefits of drug options while considering clinical and social factors such as polypharmacy, adherence, cost, convenience, and social support. Management of RA-ILD in older individuals is complex and should consider risks and benefits, while optimizing quality and quantity of life through a shared decision-making process.

After the end of the COVID-19 public health emergency, we analysed the relationship between Systemic Lupus Erythematosous (SLE) and COVID-19 from the virologist's perspective based on recent findings. SLE and COVID-19 co-morbidity present unique challenges, as individuals with SLE may be at increased risk for severe COVID-19 illness due to immune system abnormalities and ongoing therapies. Effective management of both diseases requires careful monitoring, adherence to vaccination programs, preventive measures and approved and patient-tailored therapies. This review covers various aspects, including the clinical outcome of SLE patients infected by SARS-CoV-2, the impact of this infection on SLE onset or flare-ups and the benefits of vaccination for this population. Furthermore, this review presents the most recent recommendations on clinical management of COVID-19 in rheumatic patients, including those with SLE, discussing the currently available therapeutic options. Finally, we explore the most effective tools for SARS-CoV-2 diagnosis in autoimmune conditions and examine prognostic biomarkers in COVID-19 rheumatic patients with potential implications on their clinical oversight. By adopting a comprehensive approach, we address these complexities from the virologist's perspective, aiming to improve health care for this vulnerable population.

This article provides a comprehensive review of the impact of B-cell-directed therapy on severe acute respiratory syndrome coronavirus 2 vaccine immunity, focusing on its implications in autoimmune inflammatory rheumatic diseases (AIIRD). Rituximab (RTX) is the primary B-cell-depleting drug that has been studied in AIIRD and is the focus of this review. We review the pivotal role of B cells in vaccine response and propose strategies to manage and predict vaccine responses in B-cell-depleted individuals. We highlight the need to strategize patients into distinct groups when predicting vaccine responses and developing guidelines to ensure optimal outcomes for RTX-treated patients.

Patients with Immune Mediated Inflammatory Diseases (IMIDs) using immunosuppressive therapy are at increased risk of infections, including vaccine-preventable infections. In this study, we aimed to evaluate whether patients with IMIDs on systemic immunosuppressive therapy are vaccinated according to current guidelines.

A survey was sent out, between August 2022 and March 2023, to all patients with IMIDs that visited the departments of dermatology, rheumatology and gastroenterology at an academic and regional hospital in Rotterdam, the Netherlands. Patient-reported vaccination status was compared to the Dutch guidelines on vaccinations in patients with chronic inflammatory diseases.

A total of 1,905/5,987 patients responded to the survey (response rate 32%). After exclusion of patients without systemic immunosuppressive medication, the study population comprised 1,390 patients, median age 56 years (IQR 42-66) and 41% male. Most patients (92%) had been vaccinated according to the Dutch National Immunization Program. Before starting immunosuppressive therapy, 2% of the patients who were still considered at risk according to the Dutch guideline were vaccinated for measles, and 4% for diphtheria/tetanus/polio (DT-IPV). Additionally, 62% of patients received an annual influenza vaccine, 16% received a five-yearly pneumococcal vaccine, and 91% were fully vaccinated against COVID-19.

Patients with IMIDs on immunosuppressive therapy are not vaccinated in accordance with the guidelines. Implementation strategies to improve the vaccination rates for patients with IMIDs should specifically focus on vaccinating against measles and diphtheria/tetanus/polio, and periodic vaccination against pneumococcal and influenza infections.

To evaluate the humoral response to and impact of SARS-CoV-2 vaccination in patients with systemic lupus erythematosus in a multicenter cohort design.

Data for this analysis were obtained from the Study of Safety, Effectiveness and Duration of Immunity after Vaccination against SARS-CoV-2 in Patients with Immune-Mediated Inflammatory Diseases (SAFER), a prospective, multicenter, phase IV, real-world study conducted across different regions of Brazil from June/2021 to March/2024. Patients aged >18 years with systemic lupus erythematosus (SLE) who received any one of the SARS-CoV-2 vaccines approved by the Brazilian health regulatory agency (CoronaVac [inactivated SARS-CoV-2 vaccine], ChAdOx-1 [AstraZeneca], or BNT162b2 [Pfizer-BioNTech]) were included. Immunogenicity was assessed in pre- and post-vaccination blood samples, and patients were monitored in person and remotely for the occurrence and severity of COVID-19.

Two hundred and thirty-five patients with SLE who had completed their vaccination schedules (two doses + booster dose) were included in this study. Most patients were female (89.3%) and had low disease activity or were in remission (72.4%); the majority were also on some form of immunosuppressive therapy (58.1%). One hundred and sixteen patients received two doses of CoronaVac followed by one dose of BNT162b2 (Pfizer-BioNTech) vaccine, eighty-seven received two doses of ChAdOx1-S (AstraZeneca) followed by one dose of BNT162b2 (Pfizer-BioNTech) vaccine, and thirty-two received three doses of BNT162b2 (Pfizer-BioNTech) vaccine. Twenty-eight cases of COVID-19, none meeting criteria for severe COVID-19, were recorded in patients with respiratory symptoms after the second dose of a SARS-CoV-2 vaccine. Regarding immunogenicity, an increase in seroconversion rate was observed following consecutive vaccine doses, with no difference between vaccination schedules, reaching 97.57% seropositivity after a booster dose. The geometric mean IgG titers differed between the different vaccination schedules after the first and the second vaccine dose, being lowest for the CoronaVac-based schedule, but titers were similar after the administration of a booster dose.

In patients with SLE, SARS-CoV-2 vaccines are immunogenic, inducing a robust humoral response. No severe outcomes associated with death or hospitalization were found in the evaluated patient sample. Complete vaccination schedules including a booster dose induced higher humoral responses than incomplete schedules, especially in patients initially immunized with an inactivated virus vaccine schedule and those with a suboptimal humoral response.
