Our purpose was to describe the time trend in HIV seroprevalence among homo/ bisexual men.
We analyzed 9,383 homo/ bisexual men who had a first voluntary test for HIV in 10 Spanish clinics from 1992 to 2000.
HIV prevalence decreased from 20.3% in 1992 to 8.4% in 2000. In the multivariate analysis this decline appeared independently associated with the testing year and the birth cohort.
New generations of voluntarily tested homo/bisexual men are less infected by HIV, but it is yet necessary to intensify the prevention programs.

    ABSTRACT: To describe the prevalence of HIV infection in persons tested between 1992 and 2001. Descriptive, cross-sectional epidemiological study. 10 ambulatory centers specialized in diagnosing HIV, located in 9 cities in Spain. 53,183 persons older than 12 years, tested for the first time for HIV. Number of persons tested per year, number of persons diagnosed as seropositive for HIV according to sex, age group and category of exposure. The number of persons tested increased from 4401 in 1992 to 6407 in 2001. Approximately half reported heterosexual risk exposure/exposure through high-risk heterosexual behaviors, excluding prostitution. Intravenous drug users (IVDU) increased from 15.3% in 1992-1993 to 1.4% in 2000-2001, and women prostitutes/female sex workers increased from 6.7% to 25.1%. A total of 2898 persons were diagnosed as having HIV infection; 78% of them were men. The number of diagnoses decreased from a high of 1058 in 1992-1993 to 304 in 2000-2001, and this trend was seen for all categories of exposure except female prostitutes and men with heterosexual risk factors. The prevalence decreased from 14% in 1992 to 2% in 2001. There were decreases in all categories of exposure, especially during the first years of the study, with a tendency to level off. In 2001 the prevalence figures were 23.8% for IVDU, 7.9% for homosexual men and women, 0.8% for female sex workers and 1% for other heterosexual men and women. The specialized diagnostic centers play an important role in diagnosing HIV, and this service complements primary care services. Greater efforts are needed in the prevention of HIV infection.

    ABSTRACT: To describe trends in the prevalence of HIV infection, in risk behaviors and in knowledge and attitudes related to antiretroviral therapy (ART) among men who have sex with men (MSM) recruited in Barcelona (Spain) between 1995 and 2002. Cross-sectional surveys were conducted twice yearly from 1993. MSM were recruited in saunas, sex-shops, a cruising site in a public park and by a mailing sent to all members of a gay organization, using an anonymous self-administered questionnaire. From 1995 saliva samples were requested to determine the prevalence of HIV infection. The prevalence of HIV infection remained stable from 14.2% in 1995 to 18.3% in 2002 (p > 0.05). The proportion of men who had more than 10 sexual partners in the previous 12 months showed an increasing trend (from 45.2% in 1995 to 55.7% in 2002, p < 0.0001). Unprotected anal intercourse (UAI) with casual partners did not change significantly between 1995 and 2002 (25.8% en 2002). In 2002, 55.8% of steady couples in which one or both members did not know their serological status and 27.5% of serodiscordant couples reported UAI. The proportion of men who believed that "HIV-positive persons taking ART (7.7% in 2002) or with undetectable viral load (6.4% in 2002) cannot transmit the virus" remained steady since 1998 (p > 0.05). The prevalence of HIV and risk behaviors continues to be high among MSM in Barcelona. A strategic objective in the control of the HIV epidemic must be to continue the decrease in the number of occasions on which UAI takes place between men with discordant serological status.

    ABSTRACT: Clustered cases of acute hepatitis C virus (HCV) infection, frequently accompanied by sexually transmitted diseases, have recently been reported among men who have sex with men (MSM) in several European cities. We performed a retrospective record of cases of syphilis in a large cohort of HIV-infected individuals on regular follow-up in Madrid, Spain. HCV testing was carried out in all of them. A total of 53 diagnosis of syphilis were made during the previous 4 years (2002 to 2005) in 729 HIV-infected MSM on regular follow-up. However, in only 2 of them (3.7%) asymptomatic HCV seroconversion occurred at the time of the syphilis episode. Both patients developed chronic hepatitis C. Acute HCV infection should periodically be ruled out in all HIV-infected MSM engaged in sexual risky behaviors presenting with syphilis.
