Association of Various Biomarkers and Liver Enzymes with Severity of COVID-19

Abstract

Background: Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) causing novel coronavirus (COVID-19) outbreak has an impact on the liver enzymes. The study aimed to determine the serum markers and liver enzymes and their association in COVID-19 patients admitted to hospital. Methods: It was a retrospective, observational study conducted at the Gastroenterology Department of Lahore General Hospital, from April 2020-July 2020. Total 495 patients were divided into two groups. Group A (318) comprised of patients with moderate symptoms and group B (177) with severe symptoms. Records were obtained from the hospital laboratory in which Lactate dehydrogenase (LDH), Aspartate aminotransferase, (AST), Alanine aminotransferase (ALT), Gamma glutamyl transferase (GGT) and Alkaline phosphatase (ALP) were assessed using an automated biochemistry analyzer. Serum C-reactive protein test was performed by the immunoturbidimetric assays. Serum Ferritin was determined using the ELISA technique. Results: The mean age of moderate cases was 48.57±16.84 years and of severe cases were 62.51±9.76 years. In both moderate and severe cases, males [200(63%), 98(55.36%)] were more affected than females [118(37.10%), 79(44.63%)]. Furthermore, 79(16%) of severe cases were associated with medical profession. The levels of CRP, Ferritin and LDH were increased significantly in severe COVID-19 cases (p 0.05). Conclusion: Serum ferritin, C-reactive protein and lactate dehydrogenase acts as prognostic biochemical parameters based on severity. In addition, levels of liver enzymes were also raised indicating liver derangement; however, the results were not significant.
