CRP Levels in Viral Hepatitis: A Meta-Analysis Study

Context: Viral hepatitis is a common infectious disorder with a high degree of mortality. The host immunological feedback to the hepatitis virus is dim and unable to down-regulate and clear infection. C-reactive protein (CRP), an acute phase reactant synthesized by hepatocytes in response to inflammatory reactions, facilitates apoptosis and phagocytosis. An effort has been made in the current meta-analysis study to elucidate the relationship between CRP and hepatitis B virus (HBV) and hepatitis C virus (HCV) infections. Methods: Eighteen published research articles on CRP levels of viral hepatitis patients were included in this study. A random-effects model was used to calculate the pooled mean level for CRP. Results: The pooled mean level of CRP hepatitis B and hepatitis C was 6.93 mg/L (95% CI: 3.04 - 10.81) and 2.31 mg/L (95% CI: 1.06 - 3.55), respectively. A high degree of variance was observed among the studies, with the I2 more than 90%. Conclusions: The pooled mean level of CRP was within the normal range in patients with hepatitis C; however, it was high in patients with hepatitis B. The pooled mean CRP level reported in this study can be useful to determine the level of liver damage in patients with viral hepatitis.
