Insights
Hepatitis C infection is uncommon in mentally retarded individuals in Denmark. However, hepatitis B infection markers were found to be highly prevalent in this population, especially among those with Down's syndrome.
Area of Science:
- Hepatology
- Infectious Diseases
- Public Health
Background:
- Hepatitis B and C are significant global health concerns.
- Previous studies suggest potential increased risk for certain populations.
- The prevalence of viral hepatitis in individuals with intellectual disabilities requires further investigation.
Purpose of the Study:
- To determine the prevalence of hepatitis C infection among mentally retarded individuals in Denmark.
- To compare hepatitis C prevalence with hepatitis B in this population.
- To assess if the risk of hepatitis infection is elevated in this demographic.
Main Methods:
- Serological markers for hepatitis B and C were tested in residents of an institution for the mentally retarded.
- Third-generation ELISA antibody tests were used for hepatitis C (anti-HCV).
- Tests for hepatitis B included anti-HBc and HBsAg.
Main Results:
- All participants tested negative for anti-HCV antibodies.
- A high prevalence of hepatitis B markers was observed: 35.7% anti-HBc-positive and 7.9% HBsAg-positive.
- Individuals with Down's syndrome showed significantly higher rates of hepatitis B markers (55% anti-HBc, 30% HBsAg) compared to others.
Conclusions:
- Hepatitis C infection appears uncommon among mentally retarded individuals in Denmark.
- The risk of acquiring hepatitis C is not significantly increased in this population.
- Hepatitis B seroprevalence is high in this group, consistent with prior research.
Abstract:
The objective of this study was to examine whether the prevalence of hepatitis C, like hepatitis B, is increased among the mentally retarded in Denmark. The prevalence of serological markers of hepatitis B and C was examined in an institution for the mentally retarded. A total of 126 out of 178 inhabitants (71%) with a median age of 49 years (range 23-78) participated. All subjects were anti-HCV-negative by third generation ELISA antibody test. A total of 45 (35.7%) subjects were anti-HBc-positive and 10 (7.9%) were HBsAg-positive. Among subjects with Down's syndrome (n = 20), 55% were anti-HBc-positive and 30% were HBsAg-positive as compared to 32% and 3.8% respectively among others. In conclusion, hepatitis C infection seems to be uncommon among mentally retarded persons in Denmark and the risk of acquiring infection not significantly increased as compared to that of the general population. The prevalence of serological markers for hepatitis B was high and comparable to previous studies in this population.
