Insights
Pre-existing hepatitis C infection (HCV) significantly increases mortality risk in COVID-19 patients. This association persists regardless of liver injury, suggesting extrahepatic effects of HCV worsen COVID-19 outcomes.
Area of Science:
- Hepatology
- Infectious Diseases
- Critical Care Medicine
Background:
- Limited evidence exists on the impact of pre-existing hepatitis C virus (HCV) infection on outcomes for patients with coronavirus disease 2019 (COVID-19).
- Understanding this association is crucial for managing COVID-19 patients with a history of HCV.
Purpose of the Study:
- To determine the prevalence of HCV history in COVID-19 patients.
- To investigate the relationship between HCV and in-hospital mortality, considering COVID-19-induced liver injury and other risk factors.
Main Methods:
- A retrospective single-center study included 1193 patients with COVID-19.
- Patients were categorized into those with (4.1%) and without (95.9%) a history of HCV.
- Multivariate Cox-regression and propensity score matching were employed to analyze mortality predictors.
Main Results:
- HCV, age, D-Dimer, and ferritin were identified as independent predictors of in-hospital mortality.
- No significant difference in acute liver injury or Fib-4 scores was observed between groups.
- HCV independently predicted mortality after propensity score matching, adding predictive value to clinical and laboratory parameters.
Conclusions:
- A history of HCV infection exacerbates severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) virulence in COVID-19 patients.
- This effect is independent of comorbidities, admission variables, or COVID-19-induced liver injury.
- Potential mechanisms include HCV's extrahepatic effects on viral entry, inflammation, and endothelial function.
Background:
There is little evidence about the association of pre-existing hepatitis C infection (HCV) with outcomes in patients with coronavirus disease 2019 (COVID-19).
Aim:
To assess the prevalence of history of HCV among patients with COVID-19 and to study the relationship of in-hospital mortality in relation with other predictors of poor outcomes in the presence or absence of COVID-19 induced acute liver injury.
Methods:
In a retrospective single-center study design, 1193 patients with COVID-19 infection were studied. Patients were then classified into those with and without a history of HCV, 50 (4.1%) and 1157 (95.9%) respectively.
Results:
Multivariate cox-regression models showed that age, HCV, D-Dimer, and ferritin were the only predictors of in-hospital mortality. Acute liver injury and fibrosis score (Fib-4 score) were not different between both groups. Multivariate cox-regression model for liver profile revealed that aspartate aminotransferase/ alanine aminotransferase ratio, Fib-4 score, and HCV were predictors of in-hospital mortality. After propensity score matching HCV was the only predictor of mortality in the multivariate cox-regression model. A model including HCV was found to add predictive value to clinical and laboratory parameters.
Conclusion:
In patients with COVID-19, history of HCV infection leads to an accentuated severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) virulence, irrespective of baseline comorbidities, admission laboratory variables, or COVID-19-induced liver injury, which may be related to extrahepatic effects of HCV leading to enhanced ACE-2/TMPRSS mechanisms of SARS-CoV-2 viral entry, baseline cytokine-mediated pro-inflammation, and endothelial dysfunction.

Pancreatitis is the inflammation of the pancreas, which occurs when the immune system becomes active and causes swelling, pain, and disruptions in organ function. Pancreatitis can manifest as either an acute or chronic condition.
