Hepatitis markers in a psychiatric institution
Insights
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.
Abstract:
Hepatitis A and B markers were determined in 714 patients and in 291 members of the staff of a psychiatric institution for adults. The leading diagnosis were psychosis (71.8%), neurosis (17.7%), and oligophrenia (10.6%). Anti-HAV was found in 84.4% of the patients and in 69.2% of the staff. 26.8% of the patients and 19.9% of the staff had at least one HBV marker. The frequency of HBV markers correlated with the age of the patients but not with the duration of the hospitalization. After the exclusion of IgM-anti-HAV, IgM-anti-CMV and IgM-anti-EBV or possible toxic effects, 2.6% of all patients remained as presumable non-A, non-B hepatitis infections. In this study HBV markers were not found in an hyperendemic pattern reported previously in psychiatric institutions.
