Predictors of Severity and Mortality in Chronic Liver Disease Patients With COVID-19 During the Second Wave of the Pandemic in India

Abstract

Background Coronavirus disease 2019 (COVID-19) infection in chronic liver disease patients is associated with poor outcomes. In this study, we aimed to evaluate the predictors of severity and mortality in this group of patients during the second wave of the COVID-19 pandemic in India. In addition, we compared cirrhotic patients with COVID-19 with cirrhotic patients from the pre-COVID-19 period. Methodology This was a single-center observational study. We included data from 50 patients with cirrhosis and COVID-19 retrospectively from the discharge/death files. A comparison group of 100 patients with cirrhosis from the pre-COVID period was also analyzed retrospectively. Results The majority of patients had predominantly respiratory symptoms, with fever being the most common symptom (85%). The most common presentation was acute on chronic liver failure (ACLF). The most common form of decompensation was jaundice followed by hepatic encephalopathy. The overall mortality in cirrhotic patients with COVID-19 was double than that in cirrhotic patients from the pre-COVID-19 period. All patients with ACLF succumbed to multiorgan failure. Diabetes was the only comorbidity that was associated with severe infection. Higher creatinine on admission and high D-dimer levels correlated with severity. D-dimer was the only parameter that correlated with severity and mortality on multivariate analysis. None of the comorbidities predicted mortality. Among various composite scores, the Child-Turcotte-Pugh (CTP) score and CURB-65 correlated with mortality. On the area under the receiver operating characteristic analysis, a D-dimer level of >1.1 mg/L was associated with mortality. Conclusions COVID-19 infection in patients with cirrhosis is associated with poor outcomes. D-dimer levels of >1.1 mg/L on admission are a simple parameter to predict mortality. CTP and CURB-65 are composite scores that correlate with mortality in this group of patients.
