ABSTRACT
Background Coronavirus disease 2019 (COVID-19) classically presents as a respiratory illness with fever, dry cough, and dyspnea on exertion. Along with respiratory signs and symptoms, gastrointestinal (GI) manifestations and liver injury have been recognized during the progression of the disease. This study aimed to determine the prevalence of GI symptoms and hepatic injury during COVID-19 infections and their consequences on the outcome of the disease. Methodology We conducted a retrospective survey of 715 participants age 16 or older diagnosed with COVID-19 and reported GI and hepatic manifestations in the Dammam Medical Complex in Dammam, Eastern Province, Saudi Arabia, from March 1, 2020, to May 31, 2020. We recorded clinical manifestations, laboratory test results, patient demographics, comorbidities, and treatments. Results The mean age of the study population was 46 years (88% were male, 12% were female), and 80% were non-Saudi. While most patients recovered and were discharged (n=603, 84.62%), 100 (13.99%) died due to COVID-19. Type 2 diabetes was present in 182 patients (79%) discharged and 45 patients (21%) who died. Hypertension was present in 26 (67%) discharged and 158 patients (81%) who died. Cardiovascular disease was present in 26 patients (67%) discharged and 13 (33%) who died. Chronic kidney disease was found in 11 patients (61%) discharged and six (33%) who died. Diarrhea was present in 11% of patients, nausea in 8%, and vomiting in 9% of patients. Twenty percent of patients had at least one GI symptom. Only 10% of those who died had GI symptoms, while 88% of those discharged had GI symptoms. Serum levels of alanine aminotransferase, aspartate aminotransferase, total bilirubin, alkaline phosphatase, and γ-glutamyl transpeptidase were generally higher in the patients who died than in those who were discharged. Conclusions We noted an increase in at least one liver enzyme with no clinically significant acute liver injury or cases of acute liver failure as sequelae of COVID-19. However, the presence of injury at the time of admission resulted in a significantly higher mortality rate. Only a small number of patients infected with COVID-19 exhibited GI manifestations. The etiology of severe acute respiratory syndrome coronavirus 2-related GI involvement is due to multiple factors. It is not yet fully understood if GI manifestations are clinical signs of high viral loads or another physiological process. The clinical manifestation and laboratory test results indicate that COVID-19 impacts the hepatic system and GI tract, indicating that COVID-19 infection may risk liver and GI tract injury.
