RESUMEN
OBJECTIVE: The treatment of rheumatoid arthritis-associated interstitial lung disease (RA-ILD) remains challenging due to the scarcity of proven effective therapeutic options. This study aimed to investigate the effectiveness and safety of Janus kinase inhibitors (JAKi) in RA-ILD. METHODS: We systematically reviewed the literature to identify studies evaluating the efficacy and safety of JAK inhibitors in RA-ILD. A meta-analysis was performed using the random-effects model. RESULTS: The literature search identified seven observational studies assessing the safety and efficacy of JAKi in RA-ILD and three studies analyzing the risk of developing de novo ILD in RA patients treated with JAKi. Among 183 patients with RA-ILD, the pooled analysis demonstrated an increase of 2.07 % in %pFVC (95 % CI: 0.57-3.58; p = 0.007) and 3.12 % in %pDLCO (95 % CI: 2.11-4.12; p < 0.001). Thoracic HRCT scans showed improvement in 11 % of patients (95 % CI: 0.01-0.29). The pooled proportion of patients experiencing worsening of pre-existing ILD was 5 % (95 % CI: 0.01-0.11). Adverse events were reported in 14 % of cases (95 % CI: 0.08-0.21), with the frequency of clinically significant infections ranging from 4.5 % to 25 %. The risk of developing de novo ILD in patients receiving JAKi was low, with an incidence rate of 0.20 per 1000 person-years (95 % CI: 0.14-0.25). Comparisons with abatacept and rituximab suggested similar efficacy and safety profiles. CONCLUSION: JAKi are well tolerated and might be a viable treatment option for RA-ILD, offering comparable safety and efficacy to abatacept and rituximab.

Introduction: Non-infectious inflammatory ocular diseases pose significant challenges in diagnosis and management, often requiring systemic immunosuppressive therapy. Since Janus kinase (JAK) inhibitors may represent a novel therapeutic option for these disorders, the present study aimed to expand current knowledge about their efficacy and safety in patients with these conditions. Methods: This prospective cohort study included 12 adult patients from the international AutoInflammatory Disease Alliance (AIDA) Network registries dedicated to non-infectious ocular inflammatory conditions. We assessed ocular flares, visual acuity, disease course, and complications before and after initiating JAK inhibitor therapy. Results: Ocular inflammation was related to a systemic disease in 8 (66.7%) patients as follows: spondyloarthritis (n = 3), peripheral psoriatic arthritis (n = 1), rheumatoid arthritis (n = 1), antinuclear antibodies (ANA) positive juvenile idiopathic arthritis (n = 1), Behçet's syndrome (n = 1), Vogt-Koyanagi-Harada syndrome (n = 1). In total, 4 patients received baricitinib, 1 patient received tofacitinib, and 7 patients underwent upadacitinib treatment. The overall average duration of JAK inhibitors treatment was 8.6 ± 5.5 months (ranging from 3 to 20 months). At the last assessment, ocular disease control was complete in 12/12 patients. One patient discontinued baricitinib due to poor compliance after a 12-month relapse-free period. The incidence of ocular flares was 125 episodes/1.000 person-months prior to the initiation of JAK inhibitors and 28.6 episodes/1.000 person-months thereafter. The incidence rate ratio for experiencing a relapse before starting a JAK inhibitor compared to the following period was 4.37 (95% CI 1.3-14.7, p-value: 0.02). Conclusion: JAK inhibitors demonstrate efficacy and safety in controlling ocular inflammatory relapses, confirming that they represent a valuable treatment option for patients with non-infectious inflammatory ocular diseases resistant to conventional treatments.
RESUMEN
OBJECTIVE: The search for new glucocorticoid-sparing disease-modifying anti-rheumatic drugs continues to be an unmet need in large vessel vasculitis (LVV). This report aims to assess the effectiveness and safety of leflunomide (LEF) in Takayasu arteritis (TA) and giant cell arteritis (GCA). METHODS: We systematically reviewed the literature, searching for studies evaluating the efficacy of LEF in LVV. A meta-analysis was conducted using the random-effects method. RESULTS: The literature search identified eight studies that assessed LEF in TAK and seven in GCA. All were uncontrolled observational studies with a high risk of bias, implying a low or very-low certainty of evidence. In TAK, the pooled proportion of patients achieving at least a partial remission was 75% (95% CI: 0.64-0.84), angiographic stabilization was observed in 86% (0.77-0.94) and relapses in 12% (0.05-0.21). The mean reduction in the prednisolone dose (MRPD) after LEF treatment was 15.7 mg/d (10.28-21.16). Adverse events were observed in 8% of patients (0.02-0.16). Comparison of LEF with methotrexate (MTX) or cyclophosphamide revealed LEF to be superior in terms of remission induction, relapse prevention, and tolerance. When compared with tofacitinib, both drugs demonstrated comparable efficacy. In GCA, the pooled proportion of patients achieving at least a partial remission was 60% (0.17-0.95). The MRPD after LEF treatment was 15.63 mg/d (1.29-32.55) and 53% of the patients were able to discontinue glucocorticoids (0.25 - 0.80). Relapses were observed in 21% of cases (0.14- 0.28) and adverse events in 28% (0.12-0.46). Comparison of LEF with MTX showed similar efficacy and tolerance. CONCLUSION: LEF is well tolerated and might be effective for patients with TAK and GCA.
