K Gmelin, H W Doerr, H Middelhoff

    Developments in Biological Standardization

    Summary

    This study investigated Hepatitis A and B markers in psychiatric patients and staff. While Hepatitis A was common, Hepatitis B markers were less prevalent than previously reported in similar institutions.

    Area of Science:

    • Hepatology
    • Infectious Diseases
    • Psychiatric Epidemiology

    Background:

    • Hepatitis A and B infections are significant public health concerns.
    • Previous studies suggested hyperendemic patterns of HBV in psychiatric institutions.
    • Understanding seroprevalence in vulnerable populations is crucial for public health strategies.

    Purpose of the Study:

    • To determine the seroprevalence of Hepatitis A virus (HAV) and Hepatitis B virus (HBV) markers in patients and staff at a psychiatric institution.
    • To assess the correlation between HBV markers and patient demographics like age and hospitalization duration.
    • To compare the observed HBV seroprevalence with previously reported patterns in similar settings.

    Main Methods:

    • Serological testing for Hepatitis A and B markers (including IgM antibodies) was performed on 714 patients and 291 staff members.
    • Patient diagnoses included psychosis, neurosis, and oligophrenia.
    • Statistical analysis was used to correlate marker frequency with age and hospitalization duration.

    Main Results:

    • High seroprevalence of anti-HAV was observed in both patients (84.4%) and staff (69.2%).
    • At least one HBV marker was present in 26.8% of patients and 19.9% of staff.
    • HBV marker frequency correlated with patient age but not hospitalization duration; overall HBV prevalence was lower than previously reported hyperendemic levels.

    Conclusions:

    • Hepatitis A infection is highly prevalent in this psychiatric institution's population.
    • The observed HBV marker prevalence is not hyperendemic, contrasting with prior findings in similar institutions.
    • Age is a significant factor in HBV exposure among psychiatric patients.
