Background: There are limited data worldwide on the behavior of SARSCOV2 in patients with Spondyloarthritis (SpA). Objectives: To describe the incidence and severity of COVID-19 disease in patients with SpA in Argentina. Methods: Patients with axial spondyloarthritis (AxSpA) radiological (EA) and non-radiological (AxSpA-nr) and peripheral spondyloarthritis (according to ASAS criteria) and psoriatic arthritis (PsA) (according to CASPAR criteria) were included. Sociodemographic data, comorbidities, disease activity and treatments were collected at baseline. The patients were followed up by phone or in person monthly. Data were collected from 1/4/2020 to 9/20/2020. Descriptive statistics were performed with mean and standard deviation (SD) and median and quartile 25-75 according to distribution, and the cumulative incidence (AI) of the disease was calculated. Results: 320 patients were included, of which 55% were male, with a mean age of 50 SD 13, 21.6% had a diagnosis of AS, 6.9% SpAax-nr, 6.9% SpAp, and 64.7% PsA, BASDAI 3.65 (3), BASFI 3 (1.5-9), PASI 0.3 (0-7), BSA 0.2 (0-6). Fourteen patients with a diagnosis of COVID-19 (4.4%) were reported, of which 10 diagnoses were by positive PCR and 4 by positive symptoms and close contact. 93% (13) of the cases were patients from the Province of Buenos and CABA and 1 patient from Santiago del Estero. The total IA for the country was 0.04. Of the 14 patients with COVID-19, 7 (50%) were men, 4 had a diagnosis of AS, 1 of SpAax-nr, 9 (64.3%) PsA. 100% live in urban areas, 2 (14%) have hypertension, 1 (7%) DBT, 1 (7%) COPD, 2 (14%) depression or anxiety, 11(97%) had received influenza vaccine 2020, 13 (93%), Antineumoccic 23, 14 (100%) Antineumoccic 13. Regarding the treatments: 4 (28.6%) were in treatment with anti TNF (3 with Adalimumab, 1 with certolizumab pegol), 4 (28.6%) with Anti IL17 (3 with Secukinumab, 1 with Ixekizumab), 8 (57%) with methotrexate and 2 (14%) with Leflunomide. Place of follow-up of the disease: 10 (71.4%) at home, 3 (21.4%) in the common room and 1 (7) in the intensive care unit. Treatments received for COVID-19: 1 (7%) antiretroviral, 1 (7%) antibiotic and 1 (7%) steroids. None of the patients died from COVID-19. Conclusion: An incidence of 4.4% of COVID-19 was found in this population with SpA and most of the patiend had mild symptoms and no deaths were reported. .
