Efficacy and Safety of Bimekizumab in Patients With Psoriatic Arthritis With or Without Methotrexate: 52-Week Results From Two Phase 3 Studies.

The objective of this study was to assess 52-week efficacy and safety of bimekizumab in patients with active psoriatic arthritis (PsA) with or without concomitant methotrexate (+/-MTX) treatment at baseline. We conducted a post hoc analysis of patients in BE OPTIMAL (NCT03895203; biologic disease-modifying antirheumatic drug [bDMARD]-naïve), BE COMPLETE (NCT03896581; prior inadequate response or intolerance to tumor necrosis factor inhibitors [TNFi-IR]), and the BE VITAL open-label extension (NCT04009499) study. Patients were randomized to one of the following treatment groups: bimekizumab 160 mg every four weeks, placebo, or a reference drug (adalimumab 40 mg every two weeks; BE OPTIMAL only). From Week 16, placebo-randomized patients received bimekizumab. Missing data were imputed using non-responder imputation, multiple imputation, or worst-category imputation. Through Week 52, similar proportions of bimekizumab-treated patients achieved American College of Rheumatology 50% (ACR50) response criteria for both +MTX and -MTX (BE OPTIMAL: 54.4% +MTX, 54.7% -MTX; BE COMPLETE: 56.3% +MTX, 48.0% -MTX). Similar proportions of bimekizumab-treated patients achieved complete skin clearance (Psoriasis Area and Severity Index 100% [PASI100] response) and minimal disease activity in both +MTX and -MTX groups. Similar trends were seen in placebo/bimekizumab-treated patients. Through Week 52, the proportion of bimekizumab-treated patients with ≥1 treatment-emergent adverse event were similar between the +MTX and -MTX groups (BE OPTIMAL 325 of 410 [79.3%] vs 230 of 292 [78.8%], BE COMPLETE 105 of 168 [62.5%] vs 138 of 220 [62.7%]). The safety profile was comparable between subgroups and consistent with the prior safety profile of bimekizumab. Treatment with bimekizumab demonstrated consistent, sustained efficacy to 52 weeks in bDMARD-naïve and TNFi-IR patients with PsA and was well tolerated, irrespective of concomitant MTX.

Predictors of functional improvement and pain reduction in rheumatoid arthritis patients who achieved low disease activity with disease-modifying antirheumatic drugs: a retrospective study of the FIRST Registry

BackgroundRheumatoid arthritis (RA) patients sometimes exhibit different levels of improvement in health assessment questionnaire-disability index (HAQ-DI) and subjective pain visual analogue score (VAS) even after achieving low disease activities (LDA). This study aimed to identify factors associated with improvement in HAQ-DI and pain VAS among those who achieved LDA.MethodsData of the FIRST registry, a multi-institutional cohort of RA patients treated with biological and targeted-synthetic DMARDs (b/tsDMARDs) were analyzed. Patients who were enrolled from August 2013 to February 2023 and who achieved clinical LDA [clinical disease activity index (CDAI) ≤ 10.0] at 6 months after starting treatment were included. Multiple logistic regression analyses were conducted to identify the factors that associated with achieving HAQ-DI normalization (< 0.5), HAQ-DI improvement (by > 0.22), or pain VAS reduction (≤ 40 mm).ResultsAmong 1424 patients who achieved LDA at 6 months, 732 patients achieved HAQ-DI normalization and 454 achieved pain VAS reduction. The seropositivity and the use of JAK inhibitor compared with TNF inhibitor were associated with both HAQ-DI < 0.5 and pain VAS reduction at 6 months. On the other hand, older age, past failure in ≥ 2 classes of b/tsDMARDs, higher HAQ-DI at baseline, and use of glucocorticoid were associated with the lower likelihood of HAQ-DI normalization and pain VAS reduction. Longer disease duration, being female, and higher disease activity at baseline was negatively associated HAQ-DI normalization alone. Comorbidities were not associated with the outcomes.ConclusionsThese results suggest some preferable treatment may exist for improvement of HAQ-DI and pain VAS reduction in the early stage of the treatment, which is a clue to prevention of a criteria of difficult-to-treat RA.

Axial spondyloarthritis—current aspects

Axial spondyloarthritis (axSpA) is a frequent inflammatory rheumatic disease mainly affecting the axial skeleton causing inflammatory back pain. If chronic inflammation persists new bone formation may occur possibly leading to irreversible spinal stiffness. The disease has a strong genetic background with HLA-B27 as the major factor. For diagnostic purposes, imaging is of critical importance—especially conventional radiography and magnetic resonance imaging (MRI). While the former has advantages in the detection of bony changes such as the syndesmophytes, MRI is used to detect axial inflammation but also erosions in the sacroiliac joint. Treatment follows the treat-to-target strategy starting with non-steroidal anti-inflammatory drugs (NSAIDs) in the first line, and later, if high disease activity persists, therapy with biologic disease modifying anti-rheumatic drugs (bDMARDs) is according to international recommendations indicated. For the treatment of axSpA, important targets such as tumor necrosis factor alpha (TNFα) and interleukin (IL)-17 have been identified, and several of their inhibitors (i) including some biosimilars for the former have been approved. Recently, also inhibition of Janus kinases was shown to be efficacious. There is evidence that long term inhibition of inflammation with TNFi can reduce bone formation.

Development of the paediatric society of the African league against rheumatism (PAFLAR) JIA registry and clinical profile of JIA in Africa from the PAFLAR JIA registry

BackgroundThe spectrum of Juvenile Idiopathic Arthritis (JIA) in Africa is still largely unknown. We thus set out to illustrate how we set up the PAFLAR JIA registry and describe the clinical profile of Juvenile Idiopathic Arthritis across various regions in Africa.MethodsWe carried out a retrospective observational cohort study where collaborators were trained on use of the existing PAFLAR REDCAP database to enter data for the JIA patients currently under their care capturing their epidemiological data, clinical features, laboratory investigations, diagnosis and therapy at initial diagnosis. Descriptive statistics including means, standard deviations, medians, interquartile ranges (IQR) for continuous variables and proportions for categorical variables were calculated as appropriate. Tests for difference between groups were performed between categorical variables using Pearson’s chi-square or Fisher’s exact tests. All analyses were performed using SPSS version 22 software.ResultsWe enrolled 302 patients, 58.6% (177 of 302) of whom were female. The median age of disease onset was 7 years (range 3–11 years) and the median age at diagnosis was 8.5 years (range 5–12 years). The median duration delay in diagnosis was 6 months (range 1-20.8 months). The JIA categories included Systemic JIA 18.9% (57), Oligoarticular JIA 19.2% (83), Polyarticular RF + ve 5% (15), Polyarticular RF-ve 17.9% (54), Enthesitis Related Arthritis (ERA) 18.2% (55), Psoriatic Arthritis 7% (21) and undifferentiated JIA 5.6% (17). As regards treatment the commonest therapies were NSAID therapy at 31.1%, synthetic DMARDs at 18.1%, synthetic DMARDs combined with NSAIDs at 17.5% and steroid therapy at 9.6%. Biological DMARDs accounted for 2.3% of therapies offered to our patients at diagnosis. The average JADAS score was 10.3 (range 4.8–18.2) and the average CHAQ score was 1.3 (range 0.7-2.0).ConclusionOur study highlights strategies involved in setting up a Pan-African paediatric rheumatology registry that embraces our broad diversity and the vast spectrum of JIA in Africa while comparing the various therapies available to our patients. The PAFLAR JIA registry strives to ensure a comprehensive representation of the diverse healthcare landscapes within the continent. Further longitudinal observation studies are required to ascertain the long-term outcomes of our patients and ultimately help inform policy to create a more favorable health ecosystem to support the healthcare needs of JIA patients in Africa.

Safety and Efficacy of Upadacitinib in Patients with Rheumatoid Arthritis Refractory to Biologic DMARDs: Results Through Week 216 from the SELECT-CHOICE Study.

Thesafety and efficacy of upadacitinib 15mg (UPA15) through week 216 was evaluated in patients with rheumatoid arthritis (RA) from the long-term extension (LTE) of the phase 3 SELECT-CHOICE study. Patients with RA refractory to biologic disease-modifying antirheumatic drugs (bDMARDs) were randomized to UPA15 or abatacept (ABA) for 24weeks. During the open-label LTE, patients on ABA switched to UPA15 at week 24, and those on UPA15 continued treatment. Thesafety and efficacy of continuous UPA15, and ABA to UPA15, are summarized through week 216. The LTE was comprised of 91.4% (n = 277/303) of patients that initially received UPA15, and 89.6% (n =277/309) that initially received ABA. Of patients on UPA15 in the LTE (n =547), 28.3% (n =155/547) discontinued the study drug by week 216. Relative to other adverse events of special interest, and largely consistent with previous findings at week 24, higher rates of serious infection, COVID-19, herpes zoster, and elevated creatine phosphokinase were reported, while rates of malignancy excluding nonmelanoma skin cancer (NMSC), NMSC, major adverse cardiovascular event (MACE), and venous thromboembolism (VTE) were low. Long-term safety data with UPA through week 216 aligned with previous observations and no new safety risks were identified, including in patients who switched from ABA to UPA15. Proportions of patients achieving 28-joint disease activity score based on C-reactive protein (DAS28[CRP]) < 2.6/ ≤ 3.2, clinical disease activity index (CDAI) and simple disease activity index (SDAI) low disease activity/remission, ≥ 20%/50%/70% improvement in theAmerican College of Rheumatology (ACR20/50/70) response criteria, and Boolean remission were maintained or improved with UPA15 through week 216. Improvements in theHealth Assessment Questionnaire-Disability Index (HAQ-DI), patient's assessment of pain, and Functional Assessment of Chronic Illness Therapy-Fatigue (FACIT-F) were also maintained or improved with UPA15 through week 216. Across all efficacy endpoints, similar results were observed in patients who switched from ABA to UPA15 versus continuous UPA15. Patients with an inadequate response to ≥ 1 prior tumor necrosis factor (TNF) inhibitor (UPA15: n =263/303, 86.8%; ABA to UPA15: n =273/309, 88.3%) showed similar responses to the total population. The long-term safety profile of UPA was consistent with previous findings and the broader RA clinical program. Compared to the primary analyses at week 24, efficacy responses were maintained or further improved with UPA15 through week 216 in patients with RA.

Incidence of Malignancies and the Association with Biological Disease-Modifying Antirheumatic Drugs in Japanese Patients with Rheumatoid Arthritis: A Time-Dependent Analysis from the IORRA Patient Registry.

Patients with rheumatoid arthritis (RA) may have an increased malignancy risk versus the general population, potentially elevated by biological disease-modifying antirheumatic drug (bDMARD) use. Using patient registry data, we determined malignancy risk, stratified by bDMARD use, among Japanese patients with RA versus the Japanese general population and investigated whether bDMARD use is a time-dependent risk factor for the development of malignancy. Patients aged ≥ 18years with ≥ 2 data entries of RA in the IORRA (Institute of Rheumatology, Rheumatoid Arthritis) patient registry, enrolled from January 2013-December 2018, were identified ('All RA' cohort). Patients were stratified into bDMARD (≥ 1bDMARD received) or non-bDMARD (no history of bDMARDs) sub-cohorts. Malignancy incidence rates and standardized incidence ratios (SIRs) with 95% confidence intervals (CIs) versus the Japanese general population were calculated. Risk of RA medication use was analyzed using a time-dependent Cox proportional hazards model, after adjusting for covariates. A total of 8020 patients were identified for the All RA cohort; 2187 and 5833 for the bDMARD and non-bDMARD sub-cohorts, respectively. For all three cohorts, incidence of overall malignancies was similar versus the Japanese general population. Incidence of specific malignancies was also similar, but incidence of lymphoma was higher for all three cohorts (SIRs[95% CIs] 3.72 [2.71-4.93], 5.97 [3.34-9.59], and 2.79 [1.82-4.02], respectively). In the bDMARD sub-cohort, no increase in SIRs was observed for other site-specific malignancies. Inthe All RA cohort, use of methotrexate, tacrolimus, glucocorticoids, non-steroidal anti-inflammatory drugs, and bDMARDs were not associated with the risk of overall malignancy; the hazard ratio (95% CI) was 1.36(0.96-1.93) for bDMARD use. Increased disease activity was a time-dependent risk factor of overall malignancy with a hazard ratio (95% CI) of 1.35 (1.15-1.59). The use of bDMARDs was not a time-dependent risk factor for malignancy.

A Systematic Overview of Contraindications and Special Warnings for Biologic and Targeted Synthetic Disease Modifying Antirheumatic Drugs: Establishing a Framework to Create a "Safety Checklist".

The purpose of this review is to provide an overview of the contraindications, special warnings, and boxed warnings with the aim to establish a framework to create a prescription safety checklist for a class of drugs or disease indication. This study covers biologic disease modifying antirheumatic drugs (bDMARDs) and targeted synthetic DMARDs (tsDMARDs). We identified contraindications, boxed warnings, and special warnings provided by the European Medicines Agency (EMA) and the US Food and Drug Administration (FDA). The study included b/tsDMARDs approved for treating rheumatoid arthritis (RA), psoriatic arthritis (PsA), axial spondyloarthritis (SpA), and juvenile idiopathic arthritis (JIA) within the drug-classes anti-CD20, tumor necrosis factor inhibitors (TNFi), interleukin-1 inhibitors (IL-1i), cytotoxic T-lymphocyte-associated protein (CTLA) 4, interleukin-12/23 inhibitors (IL-12/23i), interleukin 6 receptor inhibitors (IL-6Ri), Janus kinase inhibitors (JAKi), phosphodiesterase 4 inhibitors (PDE4i), interleukin-17 inhibitors (IL-17i), and interleukin-23 inhibitors (IL-23i). All drug classes, except PDE4i, had contraindications and/or warnings related to infections, including tuberculosis. A warning about herpes zoster was listed for anti-CD20, IL-1i, IL-6Ri, and JAKi, while a warning about hepatitis reactivation was listed for anti-CD20, TNFi, IL-1i, CTLA4-Ig, IL-6Ri, and JAKi. Malignancy risk was mentioned for all drug classes except PDE4i, IL-17i, and IL-23i. Other warnings included demyelinating disease (TNFi, CTLA4-Ig, and IL-6Ri), heart failure (anti-CD20 and TNFi), major adverse cardiac events (JAKi and IL-12/23) and venous thromboembolism (JAKi), hyperlipidemia (IL-6Ri and JAKi), liver impairment (TNFi, IL-1i, IL-6Ri, and JAKi), kidney impairment (IL-1i, JAKi, and PDE4i), inflammatory bowel disease (IL-17i), gastrointestinal perforation (IL-6Ri, JAKi), cytopenia (anti-CD20, TNFi, IL-1i, IL-6Ri, JAKi), and depression (PDE4i). Contraindications and warnings appeared to increase with the passage of time since the drug's approval. This review provides an overview to establish the framework to create an easily accessible and actionable prescription safety checklist from individual medical product prescription information provided by regulatory medical authorities.

Subsequent biologic and targeted synthetic disease modifying anti rheumatic drugs after fulfilling difficult-to-treat rheumatoid arthritis criteria: a survival analysis.

To evaluate the survival of different biologic or targeted-synthetic disease-modifying antirheumatic drugs (b/tsDMARD) administered after fulfilling difficult-to-treat rheumatoid arthritis (D2TRA) criteria, and to assess factors related to treatment discontinuation. Retrospective study including D2TRA patients. Drug retention of the b/tsDMARD administered after fulfilling D2TRA was assessed by Kaplan-Meier plots and the log-rank test. Cox hazard models were used to identify factors affecting treatment discontinuation. Of the 122 patients included, 75 maintained active treatment (61.5%) with a subsequent line after D2T compared to 47 (38.5%) who discontinued and required more successive lines of b/tsDMARDs. The median survival of the treatments was 78.3(7.6) months and the treatment after D2T with the better rate of survival was rituximab, followed by JAKi and IL6Ri, while worse survival rates were associated with abatacept and TNFi. Significant differences were noted among b/tsDMARDs (log-rank p < 0.01) and to evaluate these differences, a Cox regression was performed, taking each b/tsDMARD as a reference and comparing it with the others. DAS28 values 6-months after initiation of treatment were higher in those patients who discontinued treatment [4.4(1.2) vs 3.5(1.3), p = 0.01]. The multivariate cox regression model revealed that treatment choice after D2T [HR = 1.26(95%CI 1.06-1.05)] and lower DAS28 values at 6 months [HR = 1.49(95%CI 1.16-1.52)] were independent risk factors associated with treatment discontinuation. Once patients met the D2TRA criteria, the subsequent line of b/tsDMARDs with the best survival rates were rituximab, JAKi and IL6Ri. Moreover, DAS28 at 6-months of treatment after D2T was an independent risk factor for drug discontinuation. Key Points • Rituximab, IL6Ri and JAKi have better retention ratesin patients after fulfilling D2TRA criteria • Clinical disease activity in the first six months after fulfillment of D2TRA criteria is an independent risk factor of subsequent treatment survival.

When Usual Care Is Not So Usual: Protocol Violations and Generalizability in a Treat-to-Target Strategy Trial in Patients With Axial Spondyloarthritis.

The objective of this study was to evaluate the impact of protocol violations in the treat-to-target group in the Tight Control in Spondyloarthritis (TICOSPA) trial and to compare the proportion of patients optimally treated according to the Assessment of Spondyloarthritis International Society (ASAS)/EULAR 2016 recommendations for patients with axial spondyloarthritis (axSpA) between the treat-to-target versus usual care (UC) arms. This study was a cluster-randomized, controlled 48-week trial including patients with axSpA who fulfilled the ASAS criteria, had an Axial Spondyloarthritis Disease Activity Score >2.1, and were biologic disease-modifying antirheumatic drug naive. Eighteen axSpA expert centers were randomly allocated to one treatment arm: (a) treat-to-target prespecified management strategy (four-week visits), and (b) UC treatment decisions at the rheumatologist's discretion (12-week visits). Protocol violations in the treat-to-target arm and the fulfillment of the 2016 ASAS/EULAR recommendations in both arms were evaluated at every visit. ASAS Health Index (ASAS-HI) and disease activity outcomes at 48 weeks were compared between treat-to-target violators versus nonviolators. Patients treated according to the ASAS/EULAR recommendations were compared between both arms. A total of 160 patients initiated the trial (80 patients with treat to target; 80 patients with UC). In the treat-to-target arm, 51.2% patients violated the protocol at least once (62.2% of violations resulting in maintenance/reduction of treatment against protocol). After 48 weeks, treat-to-target violators versus nonviolators showed similar ratios of ASAS-HI improvement. The proportion of patients managed according to the ASAS/EULAR recommendations after the first 12 weeks were 63.9% versus 61.8% for the treat-to-target and UC arms, respectively. Protocol violations in the treat-to-target arm in the TICOSPA trial were frequent, although they did not have an impact on the rate of the primary outcome. The groups with UC was optimally treated, partly explaining the nonachievement of the primary objective in the TICOSPA trial.

Patients with High Baseline Neutrophil-to-Lymphocyte Ratio Exhibit Better Response to Filgotinib as Treatment for Rheumatoid Arthritis.

High baseline neutrophil-to-lymphocyte ratio (NLR) in rheumatoid arthritis (RA) has been associated with positive responses to biologic tumor necrosis factor inhibition and negative responses to conventional synthetic disease-modifying antirheumatic drug (csDMARD) triple therapy. Datasets from three randomized clinical trials in patients with RA were used to test the hypothesis that baseline NLR is associated with improved clinical response to filgotinib in methotrexate (MTX)-naïve or MTX-experienced RA populations. Patients from FINCH 1 (inadequate response to MTX, MTX-IR; NCT02889796), FINCH 2 (inadequate response to biologic DMARDs; NCT02873936), and FINCH 3 (MTX-naïve; NCT02886728) were classified as baseline NLR-High or baseline NLR-Low based on a previously published cut point of 2.7. In total, 3365 patients were included across the three studies. Differences in clinical outcomes and patient-reported outcomes (PROs) were determined using linear-regression models. Control-arm patients (placebo + MTX/placebo + csDMARD) classified as NLR-High exhibited worse continuous clinical and PRO responses at week 12 across clinical trials compared to NLR-Low patients. In contrast, NLR-High patients who received FIL 200mg + MTX/csDMARD exhibited consistently better responses after 12weeks compared to NLR-Low patients across clinical trials, clinical endpoints, and PROs. These trends were most prominent among the MTX-IR population. The 2.7 baseline NLR cut point could be used to enrich for patients most likely to benefit from the addition of filgotinib to background MTX/csDMARD. Use of baseline NLR as part of therapeutic decision-making would not require additional diagnostics and could contribute to improved outcomes for patients with RA.

Risk factors for vertebral fracture in rheumatoid arthritis patients using biological disease-modifying anti-rheumatic drugs (cases over 5 years): An observational study.

While biological disease-modifying anti-rheumatic drugs (bDMARDs) are considered beneficial for preventing osteoporosis and bone fracture, it is unclear whether bone loss is involved in the development of vertebral fracture, and few reports have examined the factors related to vertebral fracture in rheumatoid arthritis (RA) patients using bDMARDs. This study aims to identify factors influencing vertebral fracture in RA patients treated with bDMARDs. We retrospectively examined the records of 129 RA patients treated with bDMARDs for over 5 years. The lumbar spine and femoral bone mineral density, Disease Activity Score-28-C-Reactive Protein (DAS28-CRP) value, Simplified Disease Activity Index (SDAI), and modified Health Assessment Questionnaire (mHAQ) score were evaluated. The frequency of new vertebral fracture during the study and their risk factors were investigated. A comparison between the fracture group and the nonfracture group was performed. Multivariate analysis was performed using logistic regression analysis to detect risk factors for new vertebral fracture. The number of patients with new vertebral fracture during follow-up was 15 (11.6%) of the 129 patients in the study. Age and mHAQ score were significantly higher and lumbar spine and femoral neck bone mineral density were significantly lower in the fracture group than the nonfracture group. The risk factors for new vertebral fracture during the disease course were older age and higher mHAQ score indicating no remission over the 5 years of follow-up. In this study, there was no significant difference in disease indices such as the DAS28-CRP value and the SDAI between the fracture and nonfracture groups, suggesting an effective control of RA with bDMARDs. However, age and the mHAQ score, an index of RA dysfunction, were significantly higher in the fracture group. These results suggest that improving functional impairment may be important to prevent vertebral fracture in patients using bDMARDs.

Impact of conventional and biological disease-modifying anti-rheumatic drugs on arterial lesions in Takayasu arteritis.

The definition of Takayasu arteritis (TAK) remission and disease activity is still unclear. Vascular imaging is an essential tool for following-up patients. Herein, we aimed to compare the evolution of vascular lesions (ie vessel wall thickening and stenosis) under conventional disease-modifying anti-rheumatic drugs (cDMARDs) relatively to biological DMARDs (bDMARDs) in TAK patients followed with the same CT angiography modalities. We compared 75 lines of therapy in TAK patients who received cDMARDs (n = 40 lines) and bDMARDs (n = 35 lines) using CT angiography. We established 1-3 main target vessels with vessel wall thickening and/or stenosis. Every targeted vessel had its thickness and its lumen diameter measured at the initiation of immunosuppressive treatment and at 12 months. We observed an overall reduction of arterial wall thickness in 73% of cases and 31% had >25% of wall thickness relative decrease. Using a linear mixed effects model, first line immunosuppressive therapy (p= 0.012) and bDMARDs relatively to cDMARDs (p= 0.026) were independently associated with vessel wall thickness reduction in TAK. Thirty-eight percent of the stenotic vessels had a > 25% relative increase in lumen diameter under immunosuppressive therapy. The relative increase >25% in lumen diameter was noted in 56% vs 17% with bDMARDs compared with cDMARDs. Immunosuppressive treatments can reduce arterial wall thickness and widen lumen diameter in TAK. bDMARDs seems to be more effective than cDMARDs to improve arterial lesions in TAK.

Gender Differences in Perceptions of Psoriatic Arthritis Disease Impact, Management, and Physician Interactions: Results from a Global Patient Survey.

We evaluated the impact of gender on disease severity, health-related quality of life (HRQoL), treatment management, and patient-healthcare professional (HCP) interactions from the perspectives of patients with psoriatic arthritis (PsA). Data were collected from a global online patient survey conducted by The Harris Poll (November 2, 2017 to March 12, 2018). Eligible patients were aged ≥ 18years, with a self-reported diagnosis of PsA for > 1year, had visited a rheumatologist/dermatologist in the past 12months, and had reported previously using ≥ 1 conventional synthetic or biologic disease-modifying antirheumatic drug. Data were stratified by gender and analyzed descriptively, inferentially by binomial (chi-square) tests, and by multivariate logistic regression models. Data from 1286 patients who participated were included: 52% were female, 48% were male. Varying perceptions of disease severity between males and females were indicated by differences in symptoms leading to a diagnosis of PsA, and in symptoms reported despite treatment; more females than males reported joint tenderness, skin patches/plaques, and enthesitis. More females than males reported a major/moderate impact of PsA on their physical activity and emotional/mental well-being. Reasons for switching medication differed between genders, with more females switching because they perceived their medication to not be effective enough related to their joint symptoms. More females than males were very satisfied with their communication with their rheumatologist and were more likely to discuss the impact of PsA on their daily lives, their treatment satisfaction, and treatment goals with their rheumatologist. Patients' perceptions of the impact of PsA on HRQoL, treatment management, and interactions with HCPs varied between males and females. More females than males reported major/moderate physical and emotional impacts of PsA. When treating patients, it is important for HCPs to consider the potential impact of gender on patients' experience of PsA and its symptoms.

Effects of IL-6, JAK, TNF inhibitors, and CTLA4-Ig on knee symptoms in patients with rheumatoid arthritis

This study aims to identify factors influencing the alleviation of knee joint symptoms in patients with rheumatoid arthritis treated with biologic or target synthetic disease-modifying antirheumatic drugs (b/tsDMARDs). Among 2321 patients who started b/tsDMARDs between 2010 and 2023, we focused on 295 patients who had knee swelling or tenderness at the initiation of b/tsDMARDs and continued b/tsDMARDs at least 3 months, with recorded knee symptoms 6 months later. Symptom relief after 6 months was 78.2% for interleukin 6 (IL-6) inhibitors, 68.6% for Janus kinase (JAK) inhibitors, 65.8% for tumor necrosis factor (TNF) inhibitors, and 57.6% for cytotoxic T lymphocyte-associated antigen-4-Ig (CTLA4-Ig). The initial use of b/tsDMARDs and the use of IL-6 inhibitors in comparison to CTLA4-Ig emerged as a significant factor associated with the improvement of knee joint symptoms. Among 141 patients who underwent knee radiography at baseline and two years later, the deterioration in knee joint radiographs was 7.7% for IL-6 inhibitors, 6.3% for JAK inhibitors, 21.9% for TNF inhibitors, and 25.9% for CTLA4-Ig. The use of IL-6 inhibitors was a significant factor associated with the improvement of knee joint symptoms and the inhibition of joint destruction compared to CTLA4-Ig.

Abatacept retention and clinical effectiveness in patients with rheumatoid arthritis in a real-world setting in Taiwan.

To evaluate real-world abatacept retention and clinical outcomes in patients with rheumatoid arthritis in Taiwan. This prospective, observational study enrolled patients with rheumatoid arthritis aged ≥20 years who received abatacept in real-world practice. The primary endpoint was the abatacept retention rate at 24 months. Patients were categorized into subgroups based on abatacept treatment status and previous biological disease-modifying antirheumatic drug (bDMARD) therapy. Risk factors affecting abatacept retention were determined by regression analysis. A total of 212 patients were enrolled. The overall abatacept retention rate at 24 months among all patients was 59.9% (95% confidence interval 53.0%-66.6%). Patients who were ongoing users of abatacept and bDMARD-naïve had the highest retention rate (76.3%); of these, 31.6% achieved low disease activity or remission after 2 years. Previous treatment with bDMARDs was associated with an increased risk of abatacept discontinuation (hazard ratio 1.99; p = .002). The most common reasons for abatacept discontinuation were drug switch (11.3%) and loss to follow-up (6.1%). Abatacept was well-tolerated with no new safety signals. The 24-month retention rate of abatacept was 59.9%; abatacept was associated with improved clinical outcomes and was well-tolerated in the real-world setting in Taiwan.

Soluble CD26: From Suggested Biomarker for Cancer Diagnosis to Plausible Marker for Dynamic Monitoring of Immunotherapy.

Soluble CD26 (sCD26), a glycoprotein with dipeptidyl peptidase (DPP4) enzymatic activity, can contribute to early diagnosis of colorectal cancer and advanced adenomas and has been studied, including for prognostic purposes, across various other types of cancer and disease. The latest research in this field has confirmed that most, though not all, serum/plasma sCD26 is related to inflammation. The shedding and/or secretion of sCD26 from different immune cells are being investigated, and blood DPP4 activity levels do not correlate very strongly with protein titers. Some of the main substrates of this enzyme are key chemokines involved in immune cell migration, and both soluble and cell-surface CD26 can bind adenosine deaminase (ADA), an enzyme involved in the metabolism of immunosuppressor extracellular adenosine. Of note, there are T cells enriched in CD26 expression and, in mice tumor models, tumor infiltrating lymphocytes exhibited heightened percentages of CD26+ correlating with tumor regression. We employed sCD26 as a biomarker in the follow-up after curative resection of colorectal cancer for the early detection of tumor recurrence. Changes after treatment with different biological disease-modifying antirheumatic drugs, including Ig-CTLA4, were also observed in rheumatoid arthritis. Serum soluble CD26/DPP4 titer variation has recently been proposed as a potential prognostic biomarker after a phase I trial in cancer immunotherapy with a humanized anti-CD26 antibody. We propose that dynamic monitoring of sCD26/DPP4 changes, in addition to well-known inflammatory biomarkers such as CRP already in use as informative for immune checkpoint immunotherapy, may indicate resistance or response during the successive steps of the treatment. As tumor cells expressing CD26 can also produce sCD26, the possibility of sorting immune- from non-immune-system-originated sCD26 is discussed.
