ABSTRACT
Background: Rheumatological disease fares may be seen after many infections. However, our knowledge for the post-COVID axial spondyloarthritis (SpA) fares and its related factors is limited. Objectives: We aimed to evaluate disease activity and factors that may be associated with disease activity in axial SpA patients in post-COVID period. Methods: We retrospectively assessed the axial SpA patients who have had COVID-19 disease confrmed by a positive SARS-CoV-2 polymerized chain reaction (PCR) test result. Demographics, comorbid diseases, active medical treatments for SpA and information regarding COVID-19 clinical courses were collected from medical records. PCR positive patients were reached via telephone and Bath Ankylosing Spondylitis Disease Activity Index (BASDAI) scored for pre-and post-COVID SpA symptoms. An increase of ≥2 points in the BASDAI score was defned as fare, and SpA groups with and without fare were compared. Factors predicting SpA fare were also analyzed by the logistic regression analysis. Results: A total of 48 axial SpA patients were included in our study, 65% of them male and the mean±SD age was 42.3±8.6 years. Post-COVID SpA fare was seen in 38% patients. Demographic, clinical, medical features of the SpA patients and COVID-19 disease severity were similar between Flare and No fare groups. In comparison of the COVID-19 symptoms, although most of the COVID-19 related symptoms were similar between two groups, the frequency of the back pain and diarrhea were higher in the Flare group than No fare group. But in multivariate analysis, only history of the infammatory bowel disease had an increased risk for post-COVID SpA fare (Table 1). Conclusion: The presence of infammatory bowel disease statistically signifcant related post-COVID SpA fares. In addition, diarrhea and back pain symptoms in COVID-19 disease may be stimulating factors for SpA fares but we found no effect of rheumatological therapies.
ABSTRACT
Background: Anti-phospholipid syndrome (APS) is an autoimmune disorder characterized by presence of anti-phospholipid antibodies (aPL) comprising lupus anticoagulant, anti-β2-glycoprotein I and/or anti-cardiolipin antibodies together with recurrent thrombosis and/or obstetric morbidity. In the course of COVID-19, thromboembolism may ocur due to endothelial dysfunction directly related to the viral factor and systemic infammatory response. Concerns about COVID-19 vaccines began to arise after unexpected thromboembolic events were launched with the launch of vaccine campaigns around the world to prevent the disease. Objectives: The purpose of the study is to contribute to the literature on this subject by evaluating the development of any side effects or activation of the disease after the COVID-19 vaccine in our APS patients. Methods: This study was designed as a cross-sectional, retrospective cohort study. The patients who meet the Sapporo Criteria for APS which are followed up in Ankara City Hospital Rheumatology Clinic, 18 years and over and vaccinated with any of the COVID-19 vaccines, were included into the study. The files of the patients were examined in order to evaluate the side effects and APS disease activation (thrombosis, embolism or pregnancy complications) in the 3-month period after the last dose of the COVID-19 vaccines (CoronaVac and BNT162b2). Also, information of the patients was collected via telephone or reviewed at regular follow-up visits. Results: A total of 35 patients were included into the study (Table 1). In our patients, we did not observe any new thrombotic events or pregnancy complications during the 3-months observation period after COVID-19 vaccinations. The most common side effects after vaccinations were as follows;myalgia (30%), weakness (16.7%) and fever (10%) (Table 2). No patient became pregnant or gave birth during the follow-up. Conclusion: According to our results, no thrombotic events or pregnancy complications were observed after CoronaVac and BNT162b2 vaccines in APS patients. Apart from this, minor side effects related to COVID-19 vaccines were clinically acceptable level.
