ABSTRACT
Background/

Purpose:

Rheumatoid arthritis (RA) patients have higher COVID-19 risks [1,2]. Data suggest that some RA biologics, including baricitinib, may be beneficial for COVID-19 outcomes [3,4]. We used data from RA registry to evaluate impact of COVID-19 on RA activity in patients receiving baricitinib. Method(s) Current study is a single center registry of RA patients receiving baricitinib as a part of routine treatment. Study center accumulates most of RA patients who started baricitinib in Moscow (Russia) from July 2020 to data cutoff (January 2022). We analyzed medical records data for demographics, disease history, and change of disease activity indexes. Medical record data were allocated to visit 1 (baseline), closest to 4 and 8 months after baricitinib initiation (visits 2 and 3). Patients, who had no baricitinib interruptions, were divided in strata according to COVID status between visits 1 and 2. Result(s) At the time of data cutoff registry included data from 142 RA patients receiving baricitinib. Median duration of treatment was 14.5 (interquartile range [IQR] 10-29) weeks. Clinical RA indexes measures are compiled in Table 1. Of 142 patients, 52 had COVID-19 between visits 1 and 2 without baricitinib interruption. Swollen joint counts (SJCs) and tender joint counts (TJCs) were comparable across 3 visits except TJC at visit 3 (P < 0.05). Disease Activity Score-28 for Rheumatoid Arthritis with C-Reactive Protein (DAS28-CRP), Disease Activity Score-28 for Rheumatoid Arthritis with Erythrocyte Sedimentation Rate (DAS28-ESR) had comparable change regardless of COVID-19 status (P > 0.05). Simplified Disease Activity Index for Rheumatoid Arthritis (SDAI) and Clinical Disease Activity Index (CDAI) were higher in COVID-19 survivors at visit 3 (P < 0.05). (Table Presented) Conclusion(s) We conclude that, overall, COVID-19 had no significant impact on RA activity during baricitinib treatment. Further follow-up needed to find out reasons for TJC/SDAI/CDAI increase in COVID-19 survivors >=4 months after infection.
