Conventional Synthetic Dmards in Psoriatic Arthritis: Changing Practice in Biologic Era; Real-Life Results from HURBIO-PsA Registry

Özet

Objectives: Psoriatic arthritis is a chronic musculoskeletal disorder which may affect skin, joints, bone and enthesis. Conventional synthetic disease modifying anti-rheumatic drugs are first-line treatment options and biologic disease modifying anti-rheumatic drugs are recommended in psoriatic arthritis patients who are intolerant/not controlled well with conventional synthetic disease modifying anti-rheumatic drugs. Although survival data of the conventional synthetic disease modifying anti-rheumatic drugs without concomitant biologic disease modifying anti-rheumatic drugs are available, the effect of biologic disease modifying anti-rheumatic drugs on the retention of conventional synthetic disease modifying anti-rheumatic drugs is still a question of interest. Materials and Methods: Psoriatic arthritis patients who received at least 1 dose of biologic disease modifying anti-rheumatic drugs, using at least 1 conventional synthetic disease modifying anti-rheumatic drugs (methotrexate, leflunomide, hydroxychloroquine and sulfasalazine) at the time of biologic disease modifying anti-rheumatic drugs starting visit and registered in the Hacettepe University BIOlogical Database- Psoriatic Arthritis were included in this retrospective longitudinal analysis. Demographic and disease-specific data at first and last followup visit were collected. Unadjusted retention rate of each conventional synthetic disease modifying anti-rheumatic drugs was assessed. Overall prescription of conventional synthetic disease modifying anti-rheumatic drugs at first and last follow-up visit were compared. Results: A total of 266 (191(71.8%) female) patients was included. Median follow-up duration under biologic treatment was 43.4 (19.4- 80.1) months. Median retention duration of each conventional synthetic disease modifying anti-rheumatic drugs were similar. Between the first and last visit; there was a 29.3% decrease in methotrexate use (61.7% vs. 43.6%; p<0.001), 8.4% decrease in leflunomide use (31.2% vs. 28.6%; p=0.30), 30.0% decrease in sulfasalazine use (11.3% vs. 7.9%; p=0.05), 31.1% decrease in hydroxychloroquine use (16.9% vs. 11.7%; p=0.001), 12.5 % decrease in glucocorticoids use (51.1% vs. 44.7%; p=0.015). At last visit, 59 (22.2%) patients were conventional synthetic disease modifying anti-rheumatic drugs -free: 20 (7.5%) patients were using only glucocorticoids, 39 (14.7%) patients were conventional synthetic disease modifying anti-rheumatic drugs + glucocorticoid-free. Conclusion: Although conventional synthetic disease modifying antirheumatic drugs were significantly discontinued in an important percent of patients after the initiation of biologic disease modifying anti-rheumatic drugs, percentage of patients using glucocorticoids at last visit was still high. Studies aiming to demonstrate when, in whom and how to discontinue conventional synthetic disease modifying antirheumatic drugs are needed.
