PREVALENCE AND PREDICTIVE FACTORS ASSOCIATED WITH POSITIVITY OF SARS-COV-2 SEROLOGICAL MARKERS IN PATIENTS WITH INFLAMMATORY BOWEL DISEASE AT AN IBD REFERRAL CENTER
ABSTRACT Background: Data related to SARS-CoV-2 exposure rates in patients with inflammatory bowel diseases (IBD) are scarce. Objective - Our aim was to determine the prevalence of serological markers of SARS-Cov-2 and the predictive factors for positivity in patients with IBD. Methods: This is a cross-sectional, observational study carried out from May to September 2020. SARS-CoV-2 serological markers were determined using chemiluminescence immunoassay in 233 IBD patients without evidence of COVID-19 symptoms. Patient age was 36.6±11.1 years, 118 patients were male (50.6%), and 63.1% had Crohn’s disease. Patient clinical data were extracted from individual electronic medical records and complemented by a structured interview. Results: Twenty-six out of the 233 patients with IBD had positive serum markers for SARS-CoV-2 (11.2%). Female sex (P<0.003), extra-intestinal manifestations (P=0.004), use of corticosteroids (P=0.049), and previous contact with individuals with flu-like symptoms (P<0.001) or confirmed diagnosis of COVID-19 (P<0.001), were associated with a significant increased rate of positive SARS-Cov-2 serological markers. No significant difference was observed regarding to adherence to protection measures and positivity of SARS-Cov-2 serological markers (P>0.05). Conclusion: SARS-CoV-2 previous infection in IBD patients was not that uncommon, and its prevalence was 11.2% in our series. Positivity to SARS-CoV-2 serological markers was associated with female sex, extra-intestinal manifestations, use of corticosteroids, and contact with individuals with suspected or confirmed COVID-19. Studies with longer follow-up periods are needed to confirm these findings.
