Seroprevalence and Risk Factors for Hepatitis B, Hepatitis C, and HIV in a Substance Abuse Treatment Center

Introduction: Alcohol and substance use disorders are important public health problems with an increased risk for bloodborne and sexually transmitted infections. Objectives: To determine the frequency and risk factors of hepatitis B, hepatitis C and HIV in individuals with drug and alcohol addiction. Methodology: This prospective study was conducted in the outpatient clinic of Alcohol and Substance Abuse Treatment and Education Center (ASATEC), Izmir, Turkey. Detailed anamneses were taken from alcohol and/or drug addicts who applied to the outpatient clinic; HBV, HCV, HIV serology results in the last 6 months were examined. Results: The study group consisted of 478 persons, including 112 (23.4%) alcohol addicts, 322 (67.4%) substance addicts, and 44 (9.2%) combined alcohol and substance addicts. The mean age of the cases was 32 +/- 11 years and 432 (90.4%) were male. Drug injection and needle sharing was recorded in 16.5% and 9.8% of participants, respectively. Hepatitis B surface antigen (HBsAg) positivity was found in 2.7%, antiHCV positivity in 9.6% and HIV Ag/Ab positivity in 1.9% of the cases. Among patients using intravenous drugs, HBsAg positivity was found in 2%, anti-HCV positivity in 55%, while HIV Ag/Ab positivity was not detected. A history of sexually transmitted disease was a risk factor for HBsAg, HIV Ag/Ab positivity. Intravenous drug use, needle sharing and ecstasy use were determined as risk factors for anti-HCV positivity. Conclusions: Risky behaviors for HBV, HCV and HIV transmission are high in alcohol and substance addicts. The use of ecstasy is a novel risk factor for HCV transmission.
