Area of Science:

  • Hepatology
  • Virology
  • Epidemiology

Background:

  • Hepatitis C virus (HCV) is a primary cause of chronic liver disease worldwide.
  • Epidemiologic and natural history studies define HCV's clinical impact.
  • Lack of definitive therapy creates controversy in HCV treatment indications.

Purpose of the Study:

  • Review the epidemiology of HCV infection.
  • Summarize the natural history and clinical manifestations of HCV.
  • Discuss diagnostic modalities and current treatments for chronic HCV.

Main Methods:

  • Conducted a MEDLINE database search for English-language articles on chronic HCV infection.
  • Included data from over 500 original papers, reviews, and abstracts.

Main Results:

  • HCV is transmitted via blood and body secretions; many patients lack identifiable risk factors.
  • Most HCV infections lead to subclinical hepatitis, potentially progressing to cirrhosis and cancer.
  • Extrahepatic manifestations include porphyria cutanea tarda, cryoglobulinemia, and glomerulonephritis.

Conclusions:

  • Diagnostic tools accurately assess viral load and genotype, aiding treatment response prediction.
  • Current interferon alfa therapy has limited viral eradication success.
  • Combination therapy with ribavirin and understanding viral persistence are key for future HCV strategies.
