Core Tip

Core Tip: Chronic liver disease, particularly cirrhosis, is associated with worse outcomes in patients infected with coronavirus disease 2019 (COVID-19). This study examined the impact of COVID-19 infection on patients with chronic hepatitis C during the first COVID-19 peak in Egypt. This retrospective cohort study was performed in six Egyptian hospitals. We found that cirrhotic patients had higher rates of pneumonia, severe COVID-19, and mortality. Cirrhotic mortality was observed among decompensated patients only. Male gender, diabetes mellitus, and liver cirrhosis were independent factors associated with increased mortality risk in Egyptian patients with COVID-19 and chronic hepatitis C.
