Summary
Hepatitis B infection is highly prevalent among intravenous drug users, with many also showing signs of liver dysfunction or chronic hepatitis. This group poses a significant risk for transmitting hepatitis B and non-A non-B hepatitis.
Area of Science:
- Hepatology
- Infectious Diseases
- Addiction Medicine
Background:
- Viral liver diseases, including hepatitis B, are a significant concern in various populations.
- Drug dependents, particularly those using intravenous drugs, are at high risk for infectious diseases.
- Understanding the prevalence and impact of hepatitis B and other viral hepatitis in this demographic is crucial for public health.
Purpose of the Study:
- To survey the prevalence of viral liver disease among drug dependents attending the WAADA.
- To assess the serological markers of hepatitis B infection and the degree of liver dysfunction in this population.
- To investigate the potential for drug dependents to act as a reservoir for hepatitis B and non-A non-B hepatitis.
Main Methods:
- A survey of 130 drug dependents was conducted between August and November 1977.
- Serological tests were used to detect hepatitis B infection markers (HBsAg, Anti-HBs).
- Liver function was assessed in HBsAg-negative patients, and liver biopsies were performed on 20 individuals.
Main Results:
- 58% of drug dependents showed serological evidence of hepatitis B infection.
- 50-65% of HBsAg-negative patients exhibited some degree of liver dysfunction, potentially due to non-A non-B hepatitis.
- 80% of patients with liver biopsies had chronic hepatitis, with 45% diagnosed with chronic aggressive hepatitis.
Conclusions:
- Intravenous drug use is strongly associated with high rates of hepatitis B and other viral liver diseases.
- Drug dependents represent a significant reservoir for hepatitis B and non-A non-B hepatitis, posing a risk to the general population.
- The high carriage rate of hepatitis B in this group (80 times that of the general population) underscores the need for targeted interventions.
