Role of hepatitis C virus in acute non-A, non-B hepatitis in Greece: a 5-year prospective study

Area of Science:

• Hepatology
• Virology
• Infectious Diseases

Background:

• Hepatitis C virus (HCV) is a significant cause of viral hepatitis.
• Distinguishing HCV from other causes of non-A, non-B hepatitis is crucial for understanding disease progression.
• The Greek population's specific epidemiological profile for hepatitis requires investigation.

Purpose of the Study:

• To determine the prevalence of HCV in adults with acute non-A, non-B hepatitis.
• To investigate the correlation between HCV infection and progression to chronic hepatitis.
• To identify demographic factors influencing chronicity.

Main Methods:

• Prospective follow-up of 182 adult patients diagnosed with acute non-A, non-B hepatitis.
• Enzyme immunoassay (EIA) to detect antibodies against HCV C100-3 polypeptide.
• Statistical analysis to compare progression rates based on HCV antibody status and gender.

Main Results:

• HCV antibodies were detected in 52.7% (96/182) of patients.
• HCV was implicated in 71.9% of parenteral exposure cases versus 28.1% of community-acquired cases.
• Progression to chronic hepatitis was significantly higher in HCV antibody-positive (62.5%) versus antibody-negative (31.4%) patients (P=0.00002).
• Males showed a higher rate of chronicity (58.9%) than females (30.0%) (P=0.0001), irrespective of HCV status.

Conclusions:

• Acute hepatitis C demonstrates a high propensity for chronicity, with males being particularly susceptible.
• Community-acquired non-A, non-B hepatitis in Greece may frequently be attributed to non-HCV agents or distinct HCV strains.
