xsGastrointestinal symptoms are associated with a lower risk of hospitalization and mortality and Outcomes in COVID-19.

ABSTRACT

BACKGROUND: We aimed to find the association between gastrointestinal (GI) and respiratory symptoms with mortality and hospitalization among COVID-19 patients. METHODS: We analyzed the registered data of COVID-19 patients from February 20, 2020, to March 10, 2021. Depending on the patients' disease symptoms, four categories were defined patients with only GI symptoms, patients with only respiratory symptoms, patients with both symptoms, and patients with other symptoms. Logistic regression analysis was used to assess the association of groups with outcomes. RESULTS: A total of 42,964 patients from 23 hospitals were included, of which 26.5% patients had at least one or more GI symptoms. Of total patients, 51.58% patients were hospitalized among which 22.8% had at least one or more GI symptoms. GI symptoms significantly decreased the odds of mortality (OR 0.72, 95% CI 0.56-0.92), but respiratory symptoms increased the odds for mortality (1.36 1.24-1.50), compared with patients with other symptoms. Moreover, the odds ratio of patients who had both respiratory and GI symptoms increased (1.52 1.31-1.78) compared with patients with other symptoms. The same results were observed for hospitalization as the outcome. CONCLUSIONS: Our study showed that the presence of GI symptoms in COVID-19 at the time of admission was associated with a lower odds of hospitalization and mortality; however, this association had higher odds for respiratory symptoms.
