Objective: The coronavirus disease 2019 pandemic has been resulting in increased hospital occupancy rates. Rheumatic patients cannot still reach to hospitals, or they hesitate about going to a hospital even they are able to reach. We aimed to show the effect of the first wave of coronavirus disease 2019 pandemic on the treatment of biological disease-modifying anti-rheumatic drugs in patients with rheumatoid arthritis or spondyloarthritis. Methods: Patients were divided into three groups as follows: pre-pandemic (Pre-p: starting on biological disease-modifying anti-rheumatic drug therapy for the first time within 6 months before March 11, 2020); post-pandemic A (Post-p A: starting on biological disease-modifying anti-rheumatic drug therapy for the first time within the first 6 months after March 11, 2020); post-pandemic B (Post-p B: starting on biological disease-modifying anti-rheumatic drug therapy for the first time within the second 6 months). Results: The number of rheumatoid arthritis patients in the Post-p A and B groups decreased by 51% and 48%, respectively, as compared to the Pre-p group similar rates of reduction were also determined in the number of spondyloarthritis patients. The rates of tofacitinib and abatacept use increased in rheumatoid arthritis patients in Post-p period. Conclusion: The number of rheumatoid arthritis and spondyloarthritis patients starting on biological disease-modifying anti-rheumatic drugs for the first time decreased during the first year of the coronavirus disease 2019 pandemic.

Objective: Familial Mediterranean fever (FMF) is the most common autoinflammatory disease. Most of the identified disease-causing mutations are located on exon 10. As the number of studies about the effect of the exonal location of the mutation and its phenotypic expression is limited, we aimed to investigate whether the exonic location of the Mediterranean fever (MEFV) mutation has an effect on the clinical manifestation in patients with FMF. Methods: Study population was derived from the main FMF registry that included 2246 patients from 15 different rheumatology clinics. We categorized the mutations according to their exon locations and retrieved the clinical and demographic information from the database. Results: Patients having the MEFV mutations on exon 2 or 10 (n:1526) were divided into three subgroups according to the location of the MEFV mutations: Group 1 (exon 2 mutations), Group 2 (exon 10 mutations), and Group 3 (both exon 2 and exon 10 mutations). Group 2 patients were of a significantly younger age at onset, and erysipel-like erythema, arthritis, amyloidosis, and a family history of FMF were more common in this group. Conclusion: Patients with FMF and exon 10 mutations show more severe clinical symptoms and outcome. Exon 2 mutations tend to have a better outcome. [ABSTRACT FROM AUTHOR]
