Hepatitis E virus (HEV) infection is common in sporadic hepatitis cases in Patna, India. However, many cases lack HEV markers, suggesting other enterically transmitted viruses may be involved.

Area of Science:

  • Hepatology
  • Infectious Diseases
  • Public Health

Background:

  • Enterically transmitted non-A, non-B hepatitis in India is often attributed to Hepatitis E Virus (HEV).
  • Previous hepatitis studies primarily focused on northern, western, and south-central India.
  • Limited data exists on HEV prevalence in Eastern India.

Purpose of the Study:

  • To determine the seroprevalence of HEV infection among patients with acute sporadic hepatitis in Patna, Eastern India.
  • To investigate the potential role of other enterically transmitted viruses in unexplained hepatitis cases.

Main Methods:

  • A seroprevalence study was conducted among patients presenting with acute sporadic hepatitis.
  • Serological markers for Hepatitis A, B, and E viruses were assessed.

  • Data analysis focused on the proportion of positive anti-HEV antibodies and cases with no identifiable hepatitis markers.

    • Main Results:

    • 42% (24 of 57) of acute sporadic hepatitis cases tested positive for anti-HEV antibodies.
    • 58% (33 of 57) of cases showed no serological evidence of Hepatitis A, B, or E infection.
    • This indicates a significant burden of HEV and potentially other unidentified enterically transmitted hepatitis agents in the region.

    Conclusions:

    • HEV is a significant cause of acute sporadic hepatitis in Patna, Eastern India.
    • A substantial proportion of hepatitis cases in this region are not attributable to known hepatitis A, B, or E viruses.
    • Further research is needed to identify the causative agents of the remaining unexplained hepatitis cases.
