Impact of COVID-19 in a Cohort of Patients With Inflammatory Intestinal Disease

ABSTRACT

BACKGROUND: There are few data on the outcome of COVID-19 in patients with IBD, none in the Chilean population. The aim of the study was to describe the demographic and clinical characteristics of patients with IBD who developed COVID-19, the evolution and clinical course of IBD at 1 month follow-up after SARS-CoV-2 infection. METHOD(S) This was an observational, cross-sectional, and analytical study. Patients with positive RT-PCR SARS-Cov-2 who were followed in the IBD Program of Clinica las Condes tertiary referral center (n = 1,493), were studied by spontaneous patient consultation and/or email survey. The clinical IBD data and COVID-19 related symptoms were obtained from the medical record and follow-up telephone interviews. Statistical significance was determined (Fisher's test P < 0.05). RESULT(S) From March 1 to August 31, 2020, 32 patients were reported positive RT-PCR SARSCov- 2, 18 (56%) ulcerative colitis and 14 (44%) Crohn's disease. The median age was 32 years (range 18 - 69), 56% women. Seven patients had an additional comorbidities. At the time of infection, 9 patients and their co-habitants maintained quarantine, isolation and social distancing recommendations. Only 1 patient was clinically active at the time of infection. Ten patients (31%) were on immunomodulator/biologic maintenance treatment, of which 4 were on combination therapy. Sixty percent of patients contacted the IBD clinical team when RT-PCR SARS-Cov-2 resulted positive. The most frequent COVID-19 onset symptoms were headache (66%), myalgia (63%), and fever (50%). Four patients required hospitalization (no 1 in Critical Care Unit), none of them were on immunomodulator nor biologic treatment. Two patients received Azithromycin and 1 received steroids as treatment for COVID-19. In univariate analysis, there were no significant differences in age, diagnosis or IBD treatment in patients who required hospitalization for COVID-19 infection. Seven patients discontinued their IBD treatment during the infection (6 at the direction of the IBD Program and 1 self-discontinued therapy). Two patients had a flare of their IBD during 1 month post-COVID-19 follow-up. CONCLUSION(S) In this cohort of patients, IBD medications, including immunomodulators and biologic therapy, were not associated with a greater severity of COVID-19 infection.
