Abstract | Background: Up to half the patients diagnosed with acute coronavirus disease 2019 (COVID-19) presented with gastrointestinal symptoms. Gastric mucosal cells, enterocytes, and colonocytes express the viral entry receptor angiotensin-converting enzyme 2 (ACE2) and coreceptor transmembrane protease serine 2 (TMPRSS2) and are prone to infection. Direct infection of gastrointestinal epithelial cells has been demonstrated. COVID-19 disease was first diagnosed in Israel at the end of February 2020 with 842,536 confirmed cases and 6428 deaths by the end of June 2021. In our multicenter, retrospective cohort study, we looked for gastrointestinal signs and symptoms in two periods and correlated them with mortality. Period 1 included the first and second waves and the original virus. Period 2 represented the third wave and the alpha variant. Objectives: To reveal gastrointestinal signs and symptoms in two periods and correlate them with mortality. Methods: From 22,302 patients hospitalized in general medical centers, we randomly selected 3582 from Period 1 and 1106 from Period 2. The study was performed before vaccinations were available. Results: Gastrointestinal signs and symptoms, diarrhea, vomiting, abdominal pain, and taste/smell loss were significantly more prevalent during Period 1. Thirty-day mortality and in-hospital mortality were significantly higher in Period 2 than in Period 1, 25.20% vs. 13.68%, and 21.17% vs. 12.87%, respectively (P < 0.001). Conclusions: Thirty-day mortality and in-hospital mortality rates were 1.84 and 1.64 times higher from 6 November 2020 to 15 January 2021, the alpha variant, and in negative correlation with gastrointestinal symptoms. |
