Does the healthy hepatitis C virus carrier state really exist? An analysis using polymerase chain reaction

Area of Science:

• Hepatology
• Virology
• Immunology

Background:

• Hepatitis C virus (HCV) infection is a significant public health concern.
• Early detection and understanding of disease progression in blood donors are crucial for transfusion safety.
• The correlation between HCV viremia and liver histology in asymptomatic individuals requires further elucidation.

Purpose of the Study:

• To investigate the relationship between HCV viremia and the severity of liver disease.
• To assess histological liver abnormalities in anti-HCV-positive blood donors.
• To determine if HCV RNA presence correlates with liver injury markers in this population.

Main Methods:

• Study included 98 anti-HCV-positive blood donors.
• Methods included liver biopsy, serum HCV RNA detection via PCR, and liver injury tests.
• Histological findings were categorized, and HCV RNA levels were correlated with disease severity and ALT levels.

Main Results:

• 97% of donors exhibited histological liver abnormalities.
• HCV RNA was detected in 65% of donors, with higher prevalence in those with chronic active hepatitis (87%) compared to minimal changes (36%).
• HCV RNA-positive donors had a significantly higher incidence of chronic hepatitis (88% vs. 50%).

Conclusions:

• HCV viremia is strongly associated with the severity of liver disease in anti-HCV-positive blood donors.
• Liver biopsy remains essential for assessing disease stage in these individuals.
• The findings highlight the importance of screening blood donors for HCV to prevent transmission and manage potential liver disease.
