Association of COVID-19 with Hepatic Injury Prevalence and Associated Factors

Abstract

Background: Novel Coronavirus Disease 19 (COVID-19) was reported by the WHO as a pandemic in March 2020. It was associated with liver injury in up to 50% of patients. This retrospective cohort study investigated the prevalence and associated factors of liver injury among COVID-19 patients. Methods: We include 2319 consecutive COVID-19 patients from April 2020 to November 2020. Liver function tests were performed at baseline, 24–48 h after admission, and before mortality/discharge. We compared Saudis and non-Saudis, in admission rate, serum ALT level, morbidity, and mortality. Serum ALT was compared between sexes, admitted and non-admitted patients, and the deceased and survivors. Results: Men (1356; 58.5%) and non-Saudis (1328; 57.3%) were predominant. The mean (SD) age was 41.67 ± 18.3 years (18 - 100). One-third of the patients had comorbidities, and 1022 (44.1%) required hospital admission. Intensive Care Unit (ICU) transfer was required in 185/1022 (18%). Male and non-Saudis were most likely to be transferred to the ICU (P < 0.001). Hepatocellular liver injury was found in 797 (34.4%) patients. Male and admitted patients were more likely to have a hepatic injury (P = 0.001). The mortality rate among admitted patients was 17.8% (182/1022). Mortality was associated with older age and hepatic injury (P < 0.001 and P = 0.004, respectively). Conclusions: COVID-19 associated liver injury is common and it is associated with morbidity and mortality.
