Ulcerative Colitis in a COVID-19 Patient: A Case Report

Background: COVID-19 pneumonia is a global viral disease and has been classified as a pandemic by the World Health Organization. The coronavirus that causes it can remain in the stool of some infected patients for a short period, even after recovery from COVID-19 pneumonia. Studies have increasingly reported the involvement of other organs, including the gastrointestinal system, in addition to the respiratory system. Ulcerative colitis is an inflammatory bowel disease with an unknown cause. Emerging data suggest that the gas trointestinal system may be influenced by COVID-19 via the expression of angiotensin-converting enzyme-2 (ACE-2), but data on the association between COVID-19 and inflammatory bowel diseases, including ulcerative colitis, are lacking. In this report, we describe a case of ulcerative colitis diagnosed in a 50-year-old male patient who presented with complaints of bloody diarrhea and abdominal pain following the completion of treatment for COVID-19 pneumonia. It is possible for the novel coronavirus to trigger ulcerative colitis. Hence, patients presenting with gastrointestinal com plaints should also be evaluated for COVID-19.

Automated summary

Ulcerative colitis may be influenced by COVID-19, leading to gastrointestinal symptoms in patients. Therefore, patients with gastrointestinal symptoms should also consider whether they have COVID-19.
