Simple enzymatic screening test for viral hepatitis

V Janout, M Englis, V Sedlácek

    Journal of Hygiene, Epidemiology, Microbiology, and Immunology
    |January 1, 1980
    PubMed
    Summary

    The semi-quantitative ASAT screening examination effectively detects viral hepatitis (VH) cases in children, identifying 79% of infections. This method significantly reduced new VH cases in infection hotspots, proving its value as a reliable screening tool.

    Area of Science:

    • Hepatology
    • Pediatric Infectious Diseases
    • Public Health Screening

    Background:

    • Viral hepatitis (VH) poses a significant public health challenge, particularly in pediatric populations.
    • Early detection of VH is crucial for preventing transmission and managing the disease effectively.
    • Subclinical and anicteric VH cases often go undetected, contributing to disease spread.

    Purpose of the Study:

    • To evaluate the efficacy of a semi-quantitative ASAT screening examination for detecting VH cases in children.
    • To assess the impact of this screening method on reducing VH transmission within infection foci.
    • To determine if the ASAT screening method meets the criteria for a robust public health screening tool.

    Main Methods:

    • A 3-year study involving semi-quantitative ASAT screening examinations in pediatric groups.
    • Focus on detection of viral hepatitis (VH) cases, including anicteric and clinically unapparent infections.
    • Monitoring of VH case incidence within infection foci before and after the implementation of the screening method.

    Main Results:

    • The semi-quantitative ASAT screening examination successfully detected 79% of VH cases in the studied pediatric groups.
    • A significant proportion of detected VH cases were anicteric and clinically unapparent.
    • Implementation of the ASAT screening led to an approximate halving of additional VH cases in infection foci post-index case detection.

    Conclusions:

    • The semi-quantitative ASAT screening examination is a highly effective tool for detecting viral hepatitis (VH) in children, including asymptomatic cases.
    • This screening approach significantly curtails the spread of VH within communities by identifying and isolating cases early.
    • The ASAT screening method fulfills the essential criteria for a successful public health screening program, demonstrating its utility and reliability.
