Acute hepatitis C: prevention and treatment

Area of Science:

• Hepatology
• Virology
• Infectious Diseases

Background:

• Hepatitis C Virus (HCV) infection is a global health concern, leading to cirrhosis and hepatocellular carcinoma.
• Acute HCV infection often progresses to chronic hepatitis, with significantly lower treatment success rates compared to the acute phase.
• Improved screening and harm reduction strategies have reduced HCV prevalence in Western countries, but it remains endemic in several regions.

Purpose of the Study:

• To highlight the critical importance of recognizing and diagnosing acute Hepatitis C Virus (HCV) infection.
• To discuss the challenges in diagnosing acute HCV due to its often asymptomatic nature.
• To outline diagnostic approaches and effective treatment strategies for acute HCV infection.

Main Methods:

• Review of diagnostic methods for acute HCV, emphasizing the limitations of antibody detection.
• Focus on the utility of qualitative HCV RNA detection for early diagnosis.
• Discussion of treatment initiation following a period for spontaneous viral clearance.

Main Results:

• Acute HCV infection is frequently asymptomatic, complicating early detection.
• HCV RNA detection is a reliable diagnostic marker, appearing early after exposure.
• Spontaneous viral clearance occurs in a minority of cases, more frequently in symptomatic individuals.

Conclusions:

• Accurate diagnosis of acute HCV infection is vital for timely and effective intervention.
• Qualitative HCV RNA testing is the preferred method for diagnosing acute HCV.
• Pegylated interferon monotherapy for 24 weeks is an effective treatment option for acute HCV.
