Comparison of nailfold capillaroscopy findings in COVID-19 survivors with and without rheumatic disease: a case-control study
Öz
Purpose: The aim of this study was to evaluate the nailfold capillaroscopy (NFC) findings of patients with rheumatic disease and healthy controls (HCs) who survived coronavirus disease 2019 (COVID-19).
Materials and Methods: This study included patients with axial spondyloarthritis (axSpA), psoriatic arthritis (PsA), and rheumatoid arthritis (RA) who recovered from COVID-19 and HCs. NFC was performed for all participants. NFC findings of the three groups [patients with COVID-19 (group 1), HCs with COVID-19 (group 2), and HCs without COVID-19 (group 3)] were compared.
Results: A total of 142 individuals (group 1, n = 42; group 2, n = 50; group 3, n = 50) were included in the study. Hospitalization and oxygen therapy were more common in group 1 than in group 2. The median time from a severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2)-positive real-time polymerase chain reaction (RT-PCR) test to NFC was 10.3 (6.3–24.4) weeks in group 1 and 17.1 (6.1–44.9) weeks in group 2. All NFC findings did not differ among the groups except for capillary ramifications, which were higher in group 1 than in groups 2 and 3. Underlying rheumatic disease was the only predictor that was significantly associated with capillary ramifications.
Conclusion: The NFC findings of COVID-19 survivors with and without rheumatic disease were substantially similar to those of HCs who did not have COVID-19. Capillary ramifications may result from an underlying rheumatic disease in patients with axSpA, PsA, and RA.
