The RESIST Study: Examining Cognitive Change in Rheumatoid Arthritis Patients with Mild Cognitive Impairment Being Treated with a TNF-Inhibitor Compared to a Conventional Synthetic Disease-Modifying Anti-Rheumatic Drug.

Evidence suggests that TNF inhibitors (TNFi) used to treat rheumatoid arthritis (RA) may protect against Alzheimer's disease progression by reducing inflammation. To investigate whether RA patients with mild cognitive impairment (MCI) being treated with a TNFi show slower cognitive decline than those being treated with a conventional synthetic disease-modifying anti-rheumatic drug (csDMARD). 251 participants with RA and MCI taking either a csDMARD (N = 157) or a TNFi (N = 94) completed cognitive assessments at baseline and 6-month intervals for 18 months. It was hypothesized that those taking TNFis would show less decline on the primary outcome of Free and Cued Selective Reminding Test with Immediate Recall (FCSRT-IR) and the secondary outcome of Montreal Cognitive Assessment (MoCA). No significant changes in FCSRT-IR scores were observed in either treatment group. There was no significant difference in FCSRT-IR between treatment groups at 18 months after adjusting for baseline (mean difference = 0.5, 95% CI = -1.3, 2.3). There was also no difference in MoCA score (mean difference = 0.4, 95% CI = -0.4, 1.3). There was no cognitive decline in participants with MCI being treated with TNFis and csDMARDs, raising the possibility both classes of drug may be protective. Future studies should consider whether controlling inflammatory diseases using any approach is more important than a specific therapeutic intervention.

P117 Efficacy of filgotinib in patients with rheumatoid arthritis: Week 156 results from a long-term extension study

Abstract Background/Aims In the treatment of RA, JAK inhibitors are a valuable option to meet remission or low disease activity (LDA) treatment targets following an inadequate response (IR) or intolerance to ≥ 1 conventional synthetic disease-modifying antirheumatic drug (DMARD). FIL is a JAK1 preferential inhibitor available in two doses for the treatment of moderate to severe RA. Objectives: To evaluate long-term efficacy of two doses of FIL in clinically relevant pt populations. Methods In this interim analysis, efficacy (non-responder imputation) of FIL 200 mg (FIL200) and 100 mg (FIL100) was assessed from LTE baseline (BL) to W156 in pts with an IR to methotrexate (MTX-IR) and biologics (bDMARD-IR), enrolled from FINCH 1 (NCT02889796) and 2 (NCT02873936) parent studies (PS), respectively, receiving ≥1 FIL dose in FINCH 4 (NCT03025308). Results Study design, BL characteristics and W48 outcomes for MTX-IR1 and bDMARD-IR2 pts were reported previously. For MTX-IR and bDMARD-IR pts who received FIL200 or FIL100 in the PS, W156 remission rates using Boolean 1.0 criteria were 20.5% and 15.8%, and 18.2% and 8.9%, respectively. Adopting the Boolean 2.0 criteria slightly increased remission rates for FIL200 and FIL100 at W156: +4.2% and +4.9% for MTX-IR pts, and +1.5% and +2.4% for bDMARD-IR pts, respectively. For pts rerandomized to FIL on entering the LTE, Boolean 2.0 criteria also increased remission rates vs Boolean 1.0. Both MTX-IR and bDMARD-IR pts maintained long-term Boolean remission through W156 with FIL200 and FIL100, irrespective of prior FIL. Results for Disease Activity Score 28 with C-reactive protein (DAS28-CRP) <2.6, Clinical Disease Activity Index (CDAI) ≤2.8, and Simplified Disease Activity Index (SDAI) ≤3.3, and mean change from PS BL in Health Assessment Questionnaire-Disability Index (HAQ-DI) and pain are shown (Table). Similar trends in efficacy were seen for LDA and ACR response criteria. Conclusion In FINCH 4, both FIL200 and FIL100 showed sustained efficacy up to W156 in clinically relevant pt populations. Boolean 2.0 criteria classified more pts in remission, in line with the range reported in the validation study. Disclosure M.H.

Comparative efficacy of five approved Janus kinase inhibitors as monotherapy and combination therapy in patients with moderate-to-severe active rheumatoid arthritis: a systematic review and network meta-analysis of randomized controlled trials.

The European League of Rheumatology(EULAR)guidelines recommend Janus kinase (JAK) inhibitors for patients with moderate to severe rheumatoid arthritis (RA) who are insensitive or under-responsive to conventional synthetic disease-modifying anti-rheumatic drugs (csDMARDs). But there was no recommendation for which one was preferred in five currently approved JAK inhibitors. The objective of this network meta-analysis study was to evaluate the efficacy of five JAK inhibitors as monotherapy and combination therapy in patients with moderate-to-severe active rheumatoid arthritis. The randomized controlled trials (RCTs) of tofacitinib, baricitinib, upadacitinib, filgotinib and peficitinib as monotherapy or combined with csDMARD in the treatment of active RA were searched in database of PubMed, Embase, Web of Science and Cochrane Library, up to December 2023. The control group included placebo or csDMARD. Outcome indicators included American College of Rheumatology 20% response (ACR20), ACR50, ACR70 and the percentage of patients achieving 28-joint disease activity score using C-reactive protein (DAS28(CRP))<2.6at 12 weeks and 24 weeks. The statistical analysis was performed by Stata14 and RevMan5.4. Data processing, network evidence plots, surface under the cumulative ranking curve (SUCRA) ranking, league plots and funnel plots were generated. Risk ratio (RR) and 95% confidence interval (95%CI) as effect sizes to analyze the statistics. This study included thirty-six RCTs with 16,713 patients. All JAK inhibitors were more effective than placebo in ACR20 (RRs ranging between 1.74 and 3.08), ACR50 (RRs ranging between 2.02 and 7.47), ACR70 (RRs ranging between 2.68 and 18.13), DAS28(CRP) < 2.6 (RRs ranging between 2.70 and 7.09) at 12 weeks. Upadacitinib 30mg and upadacitinib 15mg showed relatively good efficacy according to their relative SUCRA ranking. All JAK inhibitors were more effective than csDMARD or placebo in ACR20 (RRs ranging between 1.16 and 1.86), ACR50 (RRs ranging between 1.69 and 2.84), ACR70 (RRs ranging between 1.50 and 4.47), DAS28(CRP) < 2.6 (RRs ranging between 2.28 and 7.56) at 24 weeks. Upadacitinib 15mg + csDMARD and baricitinib 4mg + csDMARD showed relatively good efficacy according to their relative SUCRA ranking. The safety analysis results such as serious infection, malignancy, major adverse cardiovascular event (MACE), and venous thromboembolic events (VTE) showed no statistical difference. This NMA study indicated that all JAK inhibitors performed better than placebo. Based on the results of this study, upadacitinib 30mg, upadacitinib 15mg, upadacitinib 15mg + csDMARD and baricitinib 4mg + csDMARD were recommended treatment options with relatively good efficacy and safety. However, attention should be paid to monitoring the occurrence of adverse events in high-risk RA patients with medication. Combination therapy with csDMARD might be more suitable for the maintenance of long-term efficacy. However, in clinical practice, it is still necessary to select the appropriate therapeutic regimen based on the actual clinical situation.

Optimising patient outcomes: temporal trends in remission rates of rheumatoid arthritis patients in the Australian OPAL dataset between 2009 and 2022.

To describe the trends in remission rates among RA patients in the OPAL dataset, spanning from 2009 to 2022, and provide insights into the effectiveness of evolving RA management approaches in real-world clinical settings. Patients with a physician diagnosis of RA and at least 3 visits between 1 January 2009 and December 2022 were identified in the OPAL dataset, an aggregated collection of data extracted from the electronic medical records of patients managed by 117 Australian rheumatologists. Demographics, disease history, prescribed medications and proportions of patients in Disease Activity Score 28-joint count C-reactive protein (DAS28CRP)) categories (remission, low disease activity (LDA), moderate disease activity (MDA) and high disease activity (HDA)) were described. A large population (n = 48,388) of eligible patients with RA were identified in the OPAL dataset. A consistent and substantial improvement in DAS28CRP remission rates were found in (i) all patients, (ii) patients managed on conventional synthetic disease-modifying antirheumatic drugs (csDMARD) and (iii) patients treated with biological or targeted synthetic (b/ts)DMARD therapy, increasing from approximately 50% in 2009 to over 70% by 2022. The increase in DAS28CRP remission was accompanied by reduced proportions of patients in MDA and HDA states. This study highlights a consistent improvement in disease activity and rising remission rates among Australian RA patients within the OPAL dataset, offering the potential for enhanced patient outcomes and reduced disease burden.

Long-term effects of abatacept on atherosclerosis and arthritis in older vs. younger patients with rheumatoid arthritis: 3-year results of a prospective, multicenter, observational study

BackgroundWe aimed to reveal the effect of abatacept (ABT) on atherosclerosis in rheumatoid arthritis (RA) patients, 3-year efficacy for arthritis, and safety in a population of older vs. younger patients.MethodsIn this open-label, prospective, observational study, patients were stratified into four groups: younger (20–64 years old) and older (≥ 65 years) patients taking ABT (AY and AO) and conventional synthetic disease-modifying antirheumatic drugs (csDMARDs) (CY and CO). Primary endpoints were change from baseline in mean intima-media thickness (IMT) of the common carotid artery, IMT max (bulbus, bifurcation, and internal and common carotid artery), and plaque score at Week 156. Disease activity, retention rate, and adverse effects were also evaluated.ResultsThe ABT group (AY + AO) tended to have smaller increases in mean IMT, max IMT, and plaque score than the csDMARD group (CY + CO) at Week 156, although the differences between groups were not statistically significant. Multivariate analysis showed significantly lower increases in plaque score with ABT than with csDMARDs, only when considering disease activity at 156 weeks (p = 0.0303). Proportions of patients with good or good/moderate European League Against Rheumatism response were higher in the ABT group, without significant difference between older and younger patients. No significant differences were observed in ABT retention rates between older and younger patients. Serious adverse effects, especially infection, tended to be more frequent with ABT than with csDMARDs, although no significant differences were found.ConclusionsABT may decelerate atherosclerosis progression and may be useful for patients with high risk of cardiovascular disease, such as older patients.Trial registration number:UMIN000014913.

Upadacitinib in Rheumatoid Arthritis and Inadequate Response to Conventional Synthetic Disease-Modifying Antirheumatic Drugs: Efficacy and Safety Through 5 Years (SELECT-NEXT).

To report 5-year efficacy and safety of upadacitinib (UPA) in rheumatoid arthritis (RA) from the phase III long-term extension (LTE) of SELECT-NEXT. Patients on stable conventional synthetic disease-modifying antirheumatic drugs were randomized to UPA 15 mg once daily (QD), UPA 30 mg QD, or placebo for 12 weeks. Following this, placebo-randomized patients were switched to UPA 15 mg QD or UPA 30 mg QD in the LTE; UPA-randomized patients continued their original dose. Blinding remained until dose switching from UPA 30 mg QD to UPA 15 mg QD because of approval of UPA 15 mg QD; the earliest switch occurred at week 168. Efficacy (as observed) and treatment-emergent adverse events (TEAEs) are reported through 5 years. Overall, 611 (92%) randomized patients entered the LTE; 271 (44%) discontinued the study drug by 5 years, primarily because of adverse events (16%). Clinical outcomes improved or were maintained at 5 years; 51% and 43% of patients achieved Clinical Disease Activity Index remission and 75% and 66% achieved Disease Activity Score in 28 joints based on C-reactive protein < 2.6 among those initially randomized to UPA 15 mg QD and UPA 30 mg QD, respectively. Proportions of patients achieving ≥ 20%/50%/70% improvement in American College of Rheumatology criteria responses increased from week 60 through 5 years. Results were similar regardless of initial randomization to UPA or placebo. TEAEs, including TEAEs of special interest, were consistent with earlier analyses and other SELECT studies. Malignancies (excluding nonmelanoma skin cancer), major adverse cardiovascular events, and venous thromboembolic events were reported infrequently. No new safety signals were observed. The 5-year benefit-risk profile for UPA in RA remains favorable. (SELECT-NEXT; ClinicalTrials.gov: NCT02675426).

Cost of treating rheumatoid arthritis in the primary care public health system in Ireland: A time-driven activity-based cost analysis

BackgroundChronic diseases are at epidemic proportions and continuing to increase in both incidence and prevalence globally. Therefore, there is a growing need to assess and improve on the value currently provided within chronic care pathways. Examining the costs associated with care pathways is a critical part of assessing this value in order to better understand and introduce potential cost-saving interventions. ObjectivesExamining one such chronic disease, Rheumatoid Arthritis (RA), this study aimed to assess the cost associated with RA in primary care within the Health Service Executive (HSE) in Ireland. MethodsFollowing mapping of the care pathway, patient vignettes based on exemplar RA patient types were used to conduct semi-structed interviews with every member (N = 21) of the primary care RA pathway. Time-Driven Activity-Based Costing (TDABC) was then used to calculate the overall cost of each patient (vignette) type. ResultsRA is an expensive condition regardless of disease stage. However, newly diagnosed patients as well as those with advanced disease in need of surgical interventions demonstrated the highest costs in terms of primary care personnel use. Additionally, patients prescribed Biological Disease-Modifying Anti-Rheumatic Drugs (bDMARDs) cost significantly more than those on Conventional Synthetic Disease-Modifying Anti-Rheumatic Drugs (csDMARDs) regardless of disease stage or personnel resource use. ConclusionRA and a subset of RA patients that exert the highest healthcare costs are growing in prevalence. Therefore, this study contributes by assessing the costs associated with RA in HSE primary care that can facilitate better understanding the current value being provided and improve upon the current care pathway to cut future costs.

Effects of tapering conventional synthetic disease-modifying antirheumatic drugs to drug-free remission versus stable treatment in rheumatoid arthritis (ARCTIC REWIND): 3-year results from an open-label, randomised controlled, non-inferiority trial

Tapering of disease-modifying antirheumatic drugs (DMARDs) to drug-free remission is an attractive treatment goal for patients with rheumatoid arthritis, although long-term effects of tapering and withdrawal remain unclear. We compared 3-year risks of flare between three conventional synthetic DMARD treatment strategies in patients with rheumatoid arthritis in sustained remission. In this open-label, randomised controlled, non-inferiority trial, we enrolled patients aged 18-80 years with rheumatoid arthritis who had been in sustained remission for at least 1 year on stable conventional synthetic DMARD therapy. Patients from ten hospitals in Norway were randomly assigned (2:1:1) with centre stratification to receive stable conventional synthetic DMARDs, half-dose conventional synthetic DMARDs, or half-dose conventional synthetic DMARDs for 1 year followed by withdrawal of all conventional synthetic DMARDs. The primary endpoint of this part of the study was disease flare over 3 years, analysed as flare-free survival and risk difference in the per-protocol population with a non-inferiority margin of 20%. This trial is registered with ClinicalTrials.gov (NCT01881308) and is completed. Between June 17, 2013, and June 18, 2018, 160 patients were enrolled and randomly assigned to receive stable-dose conventional synthetic DMARDs (n=80), half-dose conventional synthetic DMARDs (n=42), or half-dose conventional synthetic DMARDs tapering to withdrawal (n=38). Four patients did not receive the intervention and 156 patients received the allocated treatment strategy. One patient was excluded due to major protocol violation and 155 patients were included in the per-protocol analysis. 104 (67%) of 156 patients were women and 52 (33%) were men. 139 patients completed 3-years follow-up without major protocol violation; 68 (87%) of 78 patients in the stable-dose group, 36 (88%) of 41 patients in the half-dose group and 35 (95%) of 37 patients in the half-dose tapering to withdrawal group. During the 3-year study period, 80% (95% CI 69-88%) were flare-free in the stable-dose group, compared with 57% (41-71%) in the half-dose group and 38% (22-53%) in the half-dose tapering to withdrawal group. Compared with stable-dose conventional synthetic DMARDs, the risk difference of flare was 23% (95% CI 6-41%, p=0·010) in the half-dose group and 40% (22-58%, p<0·0001) in the half-dose tapering to withdrawal group, non-inferiority was therefore not shown. Adverse events were reported in 65 (83%) of 78 patients in the stable-dose group, 36 (90%) of 40 patients in the half-dose group, and 36 (97%) of 37 patients in the half-dose tapering to withdrawal group. One death occurred in the stable-dose conventional synthetic DMARD group (sudden death considered unlikely related to the study medication). Two conventional synthetic DMARD tapering strategies were associated with significantly lower rates of flare-free survival compared with stable conventional synthetic DMARD treatment, and the data do not support non-inferiority. However, drug-free remission was achiveable for a significant subgroup of patients. This trial provides information on risk and benefits of different treatment strategies important for shared decision making.

Evaluation of diagnostic and therapeutic delay in patients with rheumatoid arthritis and psoriatic arthritis

Objective. A monocentric cross-sectional study recruiting rheumatoid arthritis (RA) and psoriatic arthritis (PsA) patients residing in the Lazio region, Italy, to assess factors related to diagnostic delay and treatment accessibility. Methods. Clinical/serological data, including the time between symptom onset, diagnosis, and the beginning of treatment, were collected. Residence, referral to a rheumatologic center, physician who made the diagnosis, and previous misdiagnosis were also evaluated. Results. A higher diagnostic delay (p=0.003), and time between symptom onset and the start of I-line therapy (p=0.006) were observed in PsA compared to RA. A delayed start of II-line therapy was observed in RA compared to PsA (p=0.0007). Higher diagnostic delay (p=0.02), and time between symptom onset and the start of conventional synthetic disease-modifying antirheumatic drugs (csDMARDs) (p=0.02) were observed among residents of small-medium cities for both groups. Patients who have been diagnosed by another physician rather than a rheumatologist had a longer diagnostic delay (p=0.034) and a delayed start of I-line therapy (p=0.019). Patients who received a different previous diagnosis experienced greater diagnostic delay (p=0.03 and p=0.003) and time of start of csDMARDs (p=0.05 and p=0.01) compared with those receiving RA or PsA as the first diagnosis. PsA had a delay in starting targeted synthetic disease-modifying anti-rheumatic drugs (p=0.0004) compared to RA. Seronegative RA had delayed diagnosis (p=0.02) and beginning of therapies (p=0.03; p=0.04) compared to seropositive ones. Conclusions. According to our results, greater diagnostic delay was found in PsA compared to RA, in patients living in small-medium cities, in those who did not receive the diagnosis from a rheumatologist, in those who were previously misdiagnosed, and in seronegative RA.

The changes of intestinal flora and its relevance with memory Tfh and B cells in rheumatoid arthritis patients treated with csDMARDs and csDMARDs + bDMARDs

BackgroundA growing body of experimental and clinical evidence has implicated gut microbiota in the onset and course of rheumatoid arthritis (RA). The imbalance of intestinal flora in RA patients may lead to abnormal expression of immune cells and related cytokines. PurposeConventional synthetic disease-modifying antirheumatic drugs (csDMARDs) and conventional synthetic disease-modifying antirheumatic drugs combined with biological disease-modifying antirheumatic drugs (csDMARDs + bDMARDs) are widely used to treat RA, but the characteristics of gut microbiota before and after treatment and their relationship with memory Tfh/B cells and cytokines remain unclear. MethodsStool samples were collected from 50 RA patients and 25 healthy controls (HCs) for 16SrRNA gene sequencing. We examined the proportion of lymphocyte subsets in healthy controls and RA patients. Enzyme linked immunosorbent assay (ELISA) was used to detect the levels of related cytokines in serum. The α and β diversity of intestinal flora, and the correlation between intestinal flora and clinical indicators, lymphocyte subsets, cytokines were analyzed. ResultAt the genus level, Ruminococcaceae_Ruminococcus was decreased in the csDMARDs and csDMARDs + bDMARDs treatment group, whereas Faecalibacterium was reduced in the csDMARDs treatment group, compared to untreated group. CD4+CD45RO+CCR7+CXCR5+central memory Tfh cells and CD4+CD45RO+CCR7-CXCR5+effector memory Tfh cells were significantly lower in the csDMARDs + bDMARDs treatment group than in untreated group. CD19+CD27+IgD+pre-switched memory B cells were higher in the csDMARDs and csDMARDs + bDMARDs treatment groups, whereas CD19+CD27+IgD-switched memory B cells were significantly lower than in untreated group. Ruminococcaceae_Ruminococcus was negatively correlated with CD19+CD27+IgD+ pre-switched memory B cells but positively correlated with CD4+CD45RO+CCR7-CXCR5+effector memory Tfh and CD19+CD27+IgD-switched memory B cells in patients with RA treated with DMARDs. ConclusionThe gut microbiota, memory Tfh cells, memory B cells, and cytokines of patients with RA changed significantly under different treatment regimens and had certain correlations with the clinical indicators of RA.

Efficacy and Safety of Risankizumab for Active Psoriatic Arthritis: 100-Week Results from the Phase3 KEEPsAKE1 Randomized Clinical Trial.

Patients with psoriatic arthritis (PsA) require treatment providing durable long-term efficacy in different disease domains as well as safety. We present 100-week efficacy and safety results of risankizumab in patients with active PsA and previous inadequate response/intolerance to ≥ 1 conventional synthetic disease-modifying antirheumatic drug (csDMARD-IR). KEEPsAKE1 (NCT03675308) is a global phase3 study, including a 24-week, double-blind, placebo-controlled and ongoing open-label extension periods. Patients were randomized 1:1 to receive risankizumab 150mg or placebo at baseline and weeks4 and 16. After week24, all patients received open-label risankizumab every 12weeks thereafter. Patients were evaluated through 100weeks. Endpoints included achieving ≥ 20% reduction in American College of Rheumatology criteria for symptoms of rheumatoid arthritis (ACR20), minimal disease activity (MDA; defined as ≥ 5/7 criteria of low disease activity and extent), and other measures. Overall, 828/964 (85.9%) patients completed week100. For patients receiving continuous risankizumab, 57.3%, 70.6%, and 64.3% achieved ACR20 at weeks24, 52, and 100, respectively. For the placebo/risankizumab cohort, 33.5% achieved ACR20 at week24 but increased after switching to active treatment at weeks52 (63.7%) and 100 (62.1%). In ACR20 responders at week52, 81.2% of both treatment cohorts maintained response at week100. MDA was achieved by 25.0%, 38.3%, and 38.2% of the continuous risankizumab cohort at weeks24, 52, and 100. In the placebo/risankizumab cohort, 10.2% achieved MDA at week24, increasing at weeks52 (28.0%) and 100 (35.2%). MDA response was maintained at week100 in week52 responders in the continuous risankizumab (75.5%) and placebo/risankizumab cohorts (78.2%). Similar trends were observed for other efficacy measures. Risankizumab was generally well tolerated through 100weeks. For patients with active PsA who are csDMARD-IR, risankizumab demonstrated durable long-term efficacy and was generally well tolerated, with a consistent long-term safety profile. ClinicalTrials.gov identifier, NCT03675308.

Efficacy and Safety of Risankizumab for Active Psoriatic Arthritis: 100-Week Results from the KEEPsAKE2 Randomized Clinical Trial.

Long-term therapeutic options providing durable response and tolerability are needed for psoriatic arthritis (PsA). The ongoing KEEPsAKE2 trial is evaluating risankizumab treatment in patients with active PsA who previously had inadequate response/intolerance to ≥ 1 conventional synthetic disease-modifying antirheumatic drug (csDMARD-IR) and/or 1-2 biologic DMARDs (bDMARD-IR). Herein, we report results through 100weeks of treatment. KEEPsAKE2 is a global phase3 trial. Patients with active PsA were randomized 1:1 to double-blind subcutaneous risankizumab 150mg or placebo (weeks0, 4, and 16). At week24, all patients received open-label risankizumab every 12weeks until end of study. Efficacy endpoints included achieving ≥ 20% improvement in PsA symptoms using American College of Rheumatology criteria (ACR20), attaining minimal disease activity (MDA; meeting ≥ 5/7 criteria of low disease activity and extent), and improving in other measures. At the cutoff date, 345/443 (77.9%) patients were ongoing in thestudy. ACR20 was achieved in 57.1% and 52.5% of the continuous risankizumab and placebo/risankizumab cohorts, respectively, at week100 and in 60.0% and 55.8%, respectively, at week52. In week52 responders, maintenance of ACR20 at week100 was achieved in 74.8% (continuous risankizumab) and 78.7% (placebo/risankizumab) of patients. In the continuous risankizumab and placebo/risankizumab cohorts, respectively, MDA was achieved by 33.0% and 33.3% of patients at week100 and by 27.2% and 33.8% at week52. Among MDA responders at week52, maintenance of MDA response was achieved by 83.6% and 73.0% of the continuous risankizumab and placebo/risankizumab cohorts, respectively. Risankizumab was well tolerated through week100. Risankizumab demonstrated durable efficacy and tolerability through 100weeks; most patients who achieved ACR20 and MDA responses at week52 maintained this achievement through week100. There were no new safety signals in patients who had csDMARD-IR and bDMARD-IR. ClinicalTrials.gov NCT03671148.

Novel and potential future therapeutic options in systemic autoimmune diseases.

Autoimmune inflammation is caused by the loss of tolerance to specific self-antigens and can result in organ-specific or systemic disorders. Systemic autoimmune diseases affect a significant portion of the population with an increasing rate of incidence, which means that is essential to have effective therapies to control these chronic disorders. Unfortunately, several patients with systemic autoimmune diseases do not respond at all or just partially respond to available conventional synthetic disease-modifying antirheumatic drugs and targeted therapies. However, during the past few years, some new medications have been approved and can be used in real-life clinical settings. Meanwhile, several new candidates appeared and can offer promising novel treatment options in the future.

We aimed to estimate Coccidioides serologic screening rates before initiation of biologic disease-modifying antirheumatic drugs including tofacitinib (b/tsDMARDs), conventional synthetic disease-modifying antirheumatic drugs (csDMARDs), and/or noninhaled corticosteroids. This retrospective cohort study used 2011 to 2016 US Medicare claims data and included beneficiaries with rheumatic or autoimmune disease residing in regions within Arizona, California, and Texas endemic for Coccidioides spp. with ≥1 prescription for a b/tsDMARD, csDMARD, and/or noninhaled corticosteroid. We estimated prior-year serologic screening incidence before initiating b/tsDMARDs, csDMARD, and/or noninhaled corticosteroid. During 2012 to 2016, 4,331 beneficiaries filled 64,049 prescriptions for b/tsDMARDs, csDMARDs, and noninhaled corticosteroids. Arizona's estimated screening rate was 20.1% (95% confidence interval [95% CI] 14.5-25.7) in the year before prescription initiation for b/tsDMARDs, 8.1% (95% CI 6.5-9.7) before csDMARDs, and 6.9% (95% CI: 5.6-8.2) before corticosteroids. Screening rates for b/tsDMARDs (2.8%, 95% CI 0.0-6.7), csDMARDs (1.0%, 95% CI 0.0-2.0), and corticosteroids (0.8%, 95% CI: 0.4-1.1) were negligible in California and undetected in Texas. Adjusted screening rate before prescription for b/tsDMARDs in Arizona increased from 14.5% (95% CI 7.5-21.5) in 2012 to 26.7% (95% CI 17.6-35.8) in 2016. Rheumatologists prescribing b/tsDMARDs in Arizona screened more than other providers (20.9% [95% CI 13.9-27.9] vs 12.9% [95% CI 5.9-20.0]). Coccidioides serologic screening rates among Medicare beneficiaries with rheumatic/autoimmune diseases on b/tsDMARDs, csDMARDs, and noninhaled corticosteroids was low in Coccidioides spp.-US endemic regions between 2012 and 2016. Alignment of screening recommendations and clinical practice is needed.

Diagnosing and Treating Systemic Juvenile Idiopathic Arthritis and Adult-Onset Still's Disease as Part of the Still's Disease Continuum.

We have summarised the existing evidence supporting the concept that systemic juvenile idiopathic arthritis (sJIA) and adult-onset Still's disease (AOSD) are part of the same Still's disease spectrum. A PubMed/Embase database search was conducted using specific search strings and free text words to screen for relevant articles. The search was limited to studies in humans, published up to June 2023, in English-language. sJIA and AOSD are rare autoinflammatory disorders that have similar pathophysiological and clinical features. The clinical presentations of sJIA and AOSD are highly variable, with differential diagnoses that include a broad range of malignancies, infectious diseases, and autoimmune disorders, which contribute to delays in diagnosis. Several sets of classification exist to help diagnose patients in clinical practice; the International League of Associations for Rheumatology criteria for sJIA and the Yamaguchi and Fautrel criteria for AOSD are the most-used criteria. The therapeutic strategy for Still's disease aims to relieve signs and symptoms, prevent irreversible joint damage and potentially life-threatening complications, and avoid deleterious side effects of treatment. Recently, targeted therapies such as interleukin (IL)-1 and IL-6 inhibitors have become available for the treatment of sJIA and AOSD. While these biologics were originally largely reserved for patients in whom non-steroidal anti-inflammatory drugs, corticosteroids and conventional synthetic disease-modifying anti-rheumatic drugs had failed, they are increasingly used earlier in the treatment paradigm. Among IL-1 inhibitors, canakinumab is the only biologic approved in the US for the treatment of both sJIA and AOSD.

Immune Checkpoint Inhibitor-Associated Remitting Seronegative Symmetrical Synovitis With Pitting Edema: Description of a New Entity by CanRIO.

Remitting seronegative symmetrical synovitis with pitting edema (RS3PE) is characterized by symmetrical synovitis with pitting edema and negative rheumatoid factor (RF). It has been described in a setting of malignancy, suggesting a paraneoplastic association. With the increasing use of immune checkpoint inhibitors (ICIs) for the treatment of cancers and emergence of immune-related adverse events (irAEs), our objective was to identify and describe cases of ICI-associated RS3PE (ICI-RS3PE) and compare them to non-ICI-RS3PE. The Canadian Research Group of Rheumatology in Immuno-Oncology (CanRIO) network is a collaboration of Canadian rheumatologists with experience in the management of patients with rheumatic irAEs (Rh-irAEs). Standardized data on adult patients with Rh-irAE have been collected as part of retrospective and prospective cohorts. In this study, detailed information on all cases of ICI-RS3PE from both cohorts were extracted and analyzed. We identified 11 cases of ICI-RS3PE. The most frequently observed malignancy was nonsmall cell lung cancer (4 of 11), followed by malignant melanoma (2 of 11) and cutaneous squamous cell carcinoma (2 of 11). The median time to onset of ICI-RS3PE was 26 weeks from ICI start and 52 weeks from diagnosis of malignancy. Seven patients had stable cancer prior to onset of ICI-RS3PE, 3 had partial response, and 1 had complete response. All patients received glucocorticoids. Conventional synthetic disease-modifying antirheumatic drugs (csDMARD) were needed in 10 patients. ICI-RS3PE may be an independent Rh-irAE, separate from paraneoplastic RS3PE. The symptoms of ICI-RS3PE responded well to glucocorticoids, but concomitant treatment with csDMARDs may be necessary.

Focus on Filgotinib in Rheumatoid Arthritis: A Trial-Based Review.

Janus kinases (JAK)/Signal Transducer and Activator of Transcription (STAT) pathway is involved in pathophysiologic cascade of a notable number of rheumatic diseases. The development of JAK inhibitors has expanded treatment choices in rheumatoid arthritis (RA) with a sustained class-effect efficacy. Filgotinib is a novel selective inhibitor of JAK1 isoform licensed for use in RA and ulcerative colitis. In this review we aim to present an analysis of filgotinib's efficacy and drug-specific safety warnings. Patients with RA with or without concomitant conventional synthetic Disease-Modifying Antirheumatic Drugs (csDMARDs) (naïve or experienced) and those who have failed biologic Disease-Modifying Antirheumatic Drugs (bDMARDs) were examined in randomised clinical trials. Filgotinib was also tested against placebo, methotrexate, or adalimumab. Long-term extension trials provide insights for up to four years of continuous filgotinib administration. Beneficial effects are depicted in both disease activity parameters and quality of life indexes in moderate or severe RA with a longitudinal efficacy. In head-to-head comparison with adalimumab, filgotinib 200 mg was non-inferior. Adverse effects alerts are marked by the elevated risk of infectious adverse effects with the exception of herpes zoster infection, which has a low incidence.

Effectiveness of ixekizumab over 24 months in different clinical scenarios in psoriatic arthritis: results from the Gruppo Italiano Studio Early Arthritis multicentric prospective registry.

We aimed to evaluate ixekizumab (IXE) effectiveness, drug survival and clinical response predictors in moderate-severe psoriatic arthritis (PsA) patients in different clinical scenarios. This was a multicentre real-life observational study based on Gruppo Italiano Studio Early Arthritis (GISEA) registry of IXE treatment in PsA patients (January 2019-June 2023). Data were collected at baseline and every six months. 223 PsA outpatients were included. Statistically significant improvement was observed after 6 (T6), 12 (T12) and 24 (T24) months of therapy for tender and swollen joint count (TJC and SJC), Visual Analogue Scale (VAS)-pain and Disease Activity in PSoriatic Arthritis (DAPSA) score. DAPSA remission was reached at T12 in 22% and at T24 in 18.5% of patients. At baseline, higher fibromyalgia and combination therapy with conventional synthetic disease-modifying anti-rheumatic drugs (csDMARDs) in females with respect to males and higher Psoriasis Area Severity Index (PASI) in males than in females were observed. Therapeutic effectiveness showed in males higher DAPSA and VAS-pain reduction, higher percentage of males in DAPSA remission/low disease activity (LDA) at T6, and higher ∆PASI at T6 and T12 than in female patients. At multivariate analysis, male sex was predictive for treatment response at T6 [p=0.02, odds ratio (OR) 2.49 (95% confidence interval 1.11-5.54)], while it lost significance at T12. IXE effectiveness was highlighted after 6 months at both joint and skin levels and lasted up to 24 months in different clinical scenarios, making IXE effective in the complexity of managing PsA in a real-life setting.
