Multiple infections and associated risk factors among non-injecting cocaine users in Argentina

The aim of this study was to estimate the seroprevalence rates of human immunodeficiency virus (HIV), hepatitis B virus (HBV, core antibody), hepatitis C virus (HCV), and syphilis infections and analyze associated risk factors among 504 non-injecting cocaine users (NICU) in Buenos Aires, Argentina. Participants were interviewed in face-to-face sessions through a short structured questionnaire. Using venipuncture, 10 mL of blood was collected. Seroprevalence rates were: HIV (6.3%), HBV (9%), HCV (7.5%), and VDRL (4.2%). The risk of being infected with HIV, HBV, and HCV was significantly associated with having had a sex partner who was either a drug injector or who was known to be HIV positive. HIV and HCV infections were associated with former imprisonment, and HCV was associated with having been tattooed. Because of the rising number of NICU and the multiple infections detected, it is essential to implement prevention strategies focused on this population.

Infection epidemiological data among blood donors in Germany 2003-2004. Report of the Robert Koch Institute in accordance with Article 22 of the Transfusion Act

The Robert Koch Institute collects and evaluates data on the prevalence and incidence of HIV, hepatitis C (HCV), hepatitis B (HBV) and syphilis infections among blood and plasma donors in Germany in accordance with Article 22 of the Transfusion Act. This surveillance permits an assessment of the occurrence of infections in the blood donor population and consequently the safety of the collected donations. This report includes data from all blood donation services in Germany for 2003 and 2004. Altogether 7.09 million and 6.37 million donations or blood samples from prospective donors were screened in 2003 and 2004, respectively. In 2003 the prevalence rates of the relevant infections (per 100,000 donations) were 8.2 for HIV, 99.3 for HCV, 158.9 for HBV and 34.4 for syphilis. In 2003 the rates of seroconversion (per 100,000 donations) were 0.8 for HIV, 1.2 for HCV, 1.0 for HBV and 1.5 for syphilis in 2003. In 2004 the prevalence rates (per 100,000 donations) were 4.8 for HIV, 85.3 for HCV, 156.3 for HBV and 36.8 for syphilis. In 2004 the rates of seroconversion (per 100,000 donations) were 0.9 for HIV, 1.3 for HCV, 0.6 for HBV and 2.0 for syphilis. The analysis showed a very low incidence of infections with a decreasing trend for HCV infections and an increase in HIV and syphilis infections. The latter needs to be monitored carefully and possible causes evaluated. The quality of the reported data has improved compared to previous years. Still, some problems remain with the differentiation of the data according to sex, age and interdonation interval as well as reporting by individual blood donation centres as required by the Transfusion Act.
