Hepatitis C virus among non-injecting cocaine users (NICUs) in South America: can injectors be a bridge?

Aim: To investigate the factors associated with hepatitis C virus (HCV) infection among non-injecting cocaine users (NICUs) and to compare practices associated with HCV and HIV infection.

Design: An intercountry cross-sectional study. Setting  Buenos Aires and Montevideo metropolitan areas.

Sexual behavior and HBV infection among noninjecting cocaine users (NICUs).

The aim is to estimate HBV prevalence and the associated risks among noninjecting cocaine users (NICUs). In 2002-2003, a total of 824 NICUs from Buenos Aires (Argentina) and Montevideo (Uruguay) were interviewed using a structured questionnaire. Serologic tests were carried out for Human Immunodeficiency Virus (HIV), hepatitis B (HBV), syphilis, and others.

HIV seroincidence estimates among at-risk populations in Buenos Aires and Montevideo: use of the serologic testing algorithm for recent HIV seroconversion.

Using the serological testing algorithm for recent HIV seroconversion, we estimated annualized incidences (per 100 person-years) of HIV-1 infection in different at-risk groups in Buenos Aires and Montevideo, during a 5-year period between 1998 and 2003. HIV-positive serum samples from 9 serosurveys conducted among men who have sex with men, patients attending clinics for a sexually transmitted infections consult (STIs), female commercial sex workers, injecting drug users (IDUs), noninjecting cocaine users (NICUs), asymptomatic women screened for HIV infection, and patients with tuberculosis were used. HIV incidences were as follows: 6.

The challenge of implementation of preventive programs in a developing country: experiences, situations, and perspectives in Uruguay.

In recent years, Uruguay has seen an alarming increase in the percentage of persons with human immunodeficiency virus infection/acquired immunodeficiency syndrome who are injection drug users (IDUs) and their sex partners, which has consequently contributed to the rate of perinatal transmission. Development of preventive harm reduction and risk reduction strategies has become imperative. These strategies must be suitable for a developing country and focused on its population of IDUs.
