Rheumatic Autoimmune Diseases Following Covid-19 Infection: An Observational Study in Iraqi Kurdistan Region

ABSTRACT

Background/Aims In December 2019, a new type of novel coronavirus (COVID-19) was identified in Wuhan, China. The likelihood of developing an autoimmune and/or rheumatic diseases in COVID-19 survivors is high and a serious matter. The acute SARS-CoV-2 infection may unmask previously undiagnosed rheumatic conditions. We aimed to study rheumatic autoimmune disease manifestations diseases following COVID-19 infection survival. Methods The study was an observational case series study. The data collection was carried out in Iraqi Kurdistan region between the 1st of July 2021 and 20th of March 2022. Seventy-five patients were included the patients who previously had confirmed COVID-19 infection who developed symptoms of rheumatic autoimmune diseases post COVID-19 cure. The study was conducted via a rigorous evaluation by two rheumatologists. Patients were investigated by (ESR (mm/h) and CRP (mg/L), some autoimmune screen panel for suspecting rheumatological disease patients were sent for ANA, anti-CCP (U/ML) and rheumatoid factor (IU/M) L. Then, patients were diagnosed according to the classification criteria for suspected autoimmune diseases and those with exacerbation were evaluated clinically and by laboratory;rheumatoid arthritis by DAS28, systemic lupus erythematosus by C3, C4. Results A total of seventy-five participants post-COVID-19 infection were enrolled in this study. Age of the participants was 47.15 +/-16.18 SD, more of the participants were female (69) out of 75. For most of the patients the ESR were high with p value of 0.012, which was statistically significant. ANA was high titre in SLE patients which was (3.05+/-2.4) and in antiphospholipid syndrome p-value was significant at 0.042, Anti-CCP were positive in RA patients and in those with exacerbation of RA (44+/-10, 31.7+/-5.7 respectively), DAS28 was (4.95+/-0.59) moderate and high disease activity in patients with exacerbations. C3, C4 were low in patients with exacerbation of SLE (0.47+/-0.22, 0.03+/-0.01, respectively). Most of the patients developed symptoms post-COVID-19 between 4-10 weeks (37 participants). Conclusion Rheumatic autoimmune diseases presenting post-COVID-19 survival most commonly were systemic lupus erythematous followed by rheumatoid arthritis. and previous autoimmune diseases presented with exacerbation.
