Various liver and gastrointestinal involvements occur in patients with coronavirus disease 2019 (COVID-19) at variable prevalence. Most studies report mild liver function disturbances correlated with COVID-19 severity, though liver failure is unusual.
To study liver and gastrointestinal dysfunctions in Egyptian patients with COVID-19 and their relation to disease outcomes
This multicentre cohort study was conducted on 547 Egyptian patients from April 15, 2020 to July 29, 2020. Consecutive polymerase chain reaction-confirmed COVID-19 cases were included from four quarantine hospitals affiliated to the Egyptian ministry of health. Demographic information, laboratory characteristics, treatments, fibrosis-4 (FIB-4) index, COVID-19 severity, and outcomes were recorded and compared according to the degree of liver enzyme elevation and the presence of gastrointestinal symptoms. Follow-ups were conducted until discharge or death. Regression analyses were performed to determine the independent factors affecting mortality.
This study included 547 patients, of whom 53 (9.68%) died during hospitalization and 1 was discharged upon his request. Patients’ mean age was 45.04 ± 17.61 years, and 21.98% had severe or critical COVID-19. Alanine aminotransferase (ALT) and aspartate aminotransferase (AST) were available for 430 and 428 patients, respectively. In total, 26% and 32% of patients had elevated ALT and AST, respectively. Significant liver injury with ALT or AST elevation exceeding 3-fold was recorded in 21 (4.91%) and 16 (3.73%) patients, respectively. Male gender, smoking, hypertension, chronic hepatitis C, and lung involvement were associated with elevated AST or ALT. AST was elevated in 50% of patients over 60-years-old. FIB-4 was significantly higher in patients admitted to the intensive care unit (ICU), those with more severe COVID-19, and non-survivors. The independent variables affecting outcome were supplementary vitamin C intake (1 g daily capsules) [odds ratio (OR): 0.05, 95% confidence interval (CI): 0.008–0.337]; lung consolidation (OR: 4.540, 95%CI: 1.155–17.840); ICU admission (OR: 25.032, 95%CI: 7.110–88.128); and FIB-4 score > 3.25 (OR: 10.393, 95%CI: 2.459-43.925). Among 60 (13.98%) patients with gastrointestinal symptoms, 52 (86.67%) had diarrhoea. Patients with gastrointestinal symptoms were predominantly females with higher body mass index, and 50 (83.40%) patients had non-severe COVID-19.
Few Egyptian patients with COVID-19 developed a significant liver injury. The independent variables affecting mortality were supplementary vitamin C intake, lung consolidation, ICU admission, and FIB-4 score.
Core Tip: The prevalence and severity of liver and gastrointestinal dysfunction in patients with coronavirus disease 2019 (COVID-19) vary among populations with different underlying characteristics and disease outcomes. This is the first report from Egypt specifically exploring hepatic and gastrointestinal involvement in Egyptian patients with COVID-19. In this study, we analyzed multicentre data of patients with polymerase chain reaction-confirmed COVID-19 from April 15, 2020 to July 29, 2020. Based on these data, we assessed the degree of liver injury and presence of gastrointestinal symptoms concerning COVID-19 disease severity, intensive care unit admission, and outcome.
