This study reports a rare case of chronic hepatitis A in a patient with persistent Hepatitis A virus (HAV) replication for over 31 months, leading to significant liver damage and potential cirrhosis.

Area of Science:

  • Hepatology
  • Virology
  • Immunology

Background:

  • Hepatitis A virus (HAV) typically causes acute, self-limiting liver inflammation.
  • Chronic HAV infection is exceptionally rare, with most cases resolving within months.

Observation:

  • A patient presented with prolonged elevated aminotransferase levels and persistent IgM anti-HAV antibodies for 31 months post-infection.
  • Liver biopsy revealed moderate chronic hepatitis, and HAV RNA was detected in stool samples.
  • Esophageal varices developed 25 months after the initial hepatitis A diagnosis.

Findings:

  • Persistent replication of Hepatitis A virus (HAV) was confirmed via PCR detection of HAV RNA.
  • The patient exhibited histological evidence of chronic hepatitis and subsequent development of esophageal varices.

  • This case suggests a potential link between chronic HAV replication and progressive liver disease.

    • Implications:

    • This case highlights a rare instance of chronic hepatitis A with persistent viral replication.
    • It suggests that chronic HAV infection can lead to severe liver damage, including cirrhosis.
    • Further research is warranted to understand the mechanisms and long-term outcomes of chronic HAV infections.
