Changes in regular condom use among immigrant transsexuals attending a counselling and testing reference site in central Rome: a 12 year study.

OBJECTIVE: To analyse data from male to female transsexuals attending between 1992 and 2003 an outpatient clinic considered the main HIV counselling and testing site in Rome for foreign people. METHODS: Data collected between 1992 and 2003, from a routine anti-HIV testing and counselling activity, were analysed. A brief standard interview was performed at each test. A cross sectional analysis to assess the association of regular condom use with demographic and behavioural variables using multiple logistic regression was performed. A follow up analysis to define the effect of single factors on the occurrence of new anti-HIV seroconversions was also performed. The incidence of anti-HIV seroconversion was calculated in person years of observation. RESULTS: Overall, 473 transsexuals sex workers were tested. Most of them (99%) were from South America (mainly Columbia and Brazil). Anti-HIV prevalence was 32%, but a progressive decrease over time was observed (from 57% in 1993 to 12% in 2003). The proportion of patients reporting regular condom use at enrolment was 75%. A progressive increase in regular condom use was reported over time (from 43% in 1992-3 to 79% in 2002-3). 15 new HIV infections were observed during follow up (incidence 2.1 per 100 person years). Though the proportion of patients reporting regular condom use increased over time, 10 out of the 15 new infections occurred in patients reporting unprotected sex during follow up (rate 8.4 per 100 person years). CONCLUSIONS: Our data suggest that counselling may lead to an increase in safe sex practices among immigrant transsexuals. However, the incidence of new HIV infections is still high and mainly related to non-regular condom use, which still remains the primary objective of prevention.

HIV infection among foreign transsexual sex workers in Rome: prevalence, behavior patterns, and seroconversion rates.

BACKGROUND: The Azienda Sanitaria Locale Roma E (ASL-RME) outpatient clinic is the main reference center in Rome for HIV testing of foreign people. GOAL: To define the prevalence and incidence of HIV infection among foreign transsexual sex workers attending the center. STUDY DESIGN: A cross-sectional, follow-up study was conducted. RESULTS: Between 1993 and 1999, 353 transsexuals attended the ASL-RME. They were from Colombia (n = 208), Brazil (n = 122), and other countries (n = 23). Most of these transsexuals reported having 5 to 10 partners per day. The overall HIV prevalence was 38.2%, which multivariate analysis found to be associated with origin from Brazil and a higher number of sex partners. The observed HIV seroconversion rate was 4.1 per 100 person-years, and non-regular condom use was the only factor related to seroconversion. CONCLUSIONS: The data from this study suggest that promotion of safer sex practices and regular condom use still is the main priority among marginalized population subgroups, such as foreign prostitutes, involved in sex activities that put them at risk for HIV infection.

HIV infection among foreign people involved in HIV-related risk activities and attending an HIV reference centre in Rome: the possible role of counselling in reducing risk behaviour.

Between September 1993 and December 1995, 528 foreign individuals at risk of HIV infection attended the drug treatment centre located in the Santo Spirito Hospital in Rome, undergoing medical examination, HIV testing and counselling. The geographic distribution showed that the majority of the participants were from South America (40.0%), most of whom were transsexual sex workers (from Brazil or Columbia), and from North Africa (37.5%); all the individuals coming from Western and Eastern Europe and the USA were heroin users. The overall HIV prevalence was high (21.6%), though it varied by nationality, ranging from 5.1% among North Africans to 68.3% among Brazilian transsexuals. During the study period, 170 of the individuals returned for at least one follow-up visit. Three seroconversions occurred among the 118 initially HIV-negative immigrants who were retested, all three among the 26 HIV-negative Columbian transsexuals; the seroconversion rate within this group was 10.1 per 100 persons/years. During follow-up, there was no reduction observed in drug-related practices associated with HIV infection, yet a general increase in regular condom use was reported. The increasing number of foreign persons contacting our programme emphasizes the need for easy access to care and treatment for marginalized populations possibly engaging in behaviour at risk for HIV infection. Counselling strategies seem to be relatively effective in promoting safer sex among these population groups.

Syphilis serology among transvestite prostitutes attending an HIV unit in Rome, Italy.

Sixty-seven transvestite prostitutes from Latin America (49 from Brazil and 18 from Colombia) who attended an HIV unit located in the inner city of Rome between January 1991 and June 1992 were studied for syphilis markers by means of both the Treponema pallidum haemoagglutination test (TPHA) and a solid phase haemadsorption test for detection of specific IgM (SPHA-IgM) which are typically present in recent infections. All participants reported more than 500 sexual partners in the past year, and 67.1% of them more than 1500 partners (between 5 and 10 partners per working day). The overall prevalence of anti-HIV antibodies in this population was 65.7%. The prevalence of positive TPHA tests in the population studied was 73.1%, while that of positive SPHA-IgM tests was 10.4%. The prevalence of positive TPHA and SPHA-IgM tests was higher among Columbians than among Brazilians (83.3% vs 69.4% and 22.2% vs 6.1%, respectively) and also showed a positive correlation with the duration of their permanence in Italy. The TPHA and SPHA-IgM positivities were significantly higher among subjects older than 29 years. Positive TPHA was also significantly higher in subjects who reported a history of heroin and/or cocaine abuse while positive SPHA-IgM was higher in subjects who did not use condoms or reported irregular use of them than in subjects who regularly used condoms. No overall correlation was evident between TPHA positivity and anti-HIV positivity, while SPHA-IgM positivity was found to be higher among anti-HIV-negative subjects.(ABSTRACT TRUNCATED AT 250 WORDS)

Understanding the dynamics of the HIV epidemic among Italian intravenous drug users: a cross-sectional versus a longitudinal approach.

We studied annual human immunodeficiency virus (HIV) seroprevalence and incidence in a large number of intravenous drug users attending drug treatment centers in three Italian urban areas. We also evaluated risk factors for HIV seropositivity and for HIV seroconversion. The results showed that HIV prevalence and incidence are declining. HIV prevalence declined dramatically in study participants that were < 25 years old. Prevalent HIV cases were associated with older age and longer duration of intravenous drug use; however, short duration of drug use increased the risk of seroconversion. The findings of our study suggest that comparing cross-sectional and longitudinal data contributes to a better understanding of the dynamics of the HIV epidemic among intravenous drug users.

Impact of HIV infection on non-AIDS mortality among Italian injecting drug users.

OBJECTIVES: To estimate the excess mortality of injecting drug users (IDU) stratified by HIV serostatus compared with the general population in Italy. To compare total and cause-specific mortality in HIV-positive versus HIV-negative IDU, in order to identify possible HIV-related non-AIDS causes of death in this population. METHODS: All IDU attending two drug-treatment centres in Rome who underwent HIV testing between 1985 and 1991 were enrolled into a prospective study. The end-point of the study was death from any cause by 31 December 1991. Mortality rates were compared using age-adjusted standardized mortality ratios and person-time techniques. RESULTS: Of the 2431 IDU, 1661 (68.3%) were HIV-seronegative and 82 seroconverted. Of 181 deaths, comprising 89 from AIDS and 92 from other causes, the mortality rate was 4.5 and 0.8 per 100 person-years in HIV-seropositives and HIV-seronegatives, respectively. For non-AIDS mortality in HIV-seropositives, the overall rate was 1.7 per 100 person-years. Deaths from overdose and endocarditis/embolus tended to be higher in HIV-seropositive than HIV-seronegative IDU, although there was no difference in the rate of deaths due to pneumonia by HIV serostatus. CONCLUSIONS: These data are consistent with other studies demonstrating a higher frequency of mortality among HIV-seropositive IDU. The excess in overdose mortality among HIV-seropositives is disturbing and merits further investigation.

Behavioural patterns and HIV infection among drug using transvestites practising prostitution in Rome.

Fifty-seven male prostitutes who were also drug users, underwent HIV-1 testing in a drug dependency unit in Rome. The overall prevalence of HIV antibody was 74% (42/57). Of the 57 subjects, 46 completed a standard questionnaire and were interviewed by a trained psychologist about use of drugs, sexual and AIDS-related behaviours. Among the 46 patients responding to the questionnaire, the prevalence of HIV was 67% (31/46). HIV prevalence increased with the duration of drug use, rising from 48% for less than 2 years use, to 64% for 2 to 4 years, and 100% for more than 4 years. It also increased with duration of stay in Italy: from 59% for less than 2 years, 78% for 2-4 years and to 83% for more than 4 years. Prevalence of HIV antibody was higher among those who reported injecting drugs (73% vs 63%), or who reported needle sharing (83% vs 62%). Higher prevalence was also related to the number of partners in the last year (74% for more than 1,500 partners vs 50% for less than 1,500), and to non-use of condoms (70% for 'sometimes/never' vs 50% for 'always'). The results indicate that further educational outreach efforts are required among male transvestite prostitutes since they may constitute a potential source of infection for their clients.

Sexual lifestyle / behavioral changes in a cohort of intravenous drug users.

PIP: This article reports on a study of HIV seroprevalence and sexual lifestyles among Italian intravenous drug users (IVDUs). Unlike the situation in the US and most of Europe, where HIV infection is found primarily among homosexual and bisexual men, intravenous drug users account for 66% of the hiv cases in Italy. This study, which ran from January through March of 1990, involved interviews with 124 IV heroin users having methadone treatment in a Public Assistance Center in Rome. The goals of the study included conducting a demographic survey and investigation of the serological condition of IVDUs, investigating the sexual behavior of both HIV positive and negative subjects, and investigating any changes in the sexual habits of the subjects following awareness of their serological condition. 34 of those interviewed were women and 90 were men. Ages ranged from 18-41 years. Of the 124 subjects, 120 were heterosexual, 2 homosexual, and 2 bisexual. 39 heterosexuals, as well as the 2 homosexuals and the 2 bisexuals, tested HIV positive. 96% of the IVDUs interviewed reported being sexually active, and 67% indicated having at least 1 sexual intercourse a week (28% reported 10 or less sexual intercourses in a year). Although all those interviewed acknowledged being aware of the risk of sexually transmitted AIDS, 60% of the HIV positive and 88% of the HIV negative subjects did not use condoms regularly (56% of the HIV negative subjects never used condoms). The article lists some of the reasons given for irregular use of condoms. Concerning changes in sexual habits, 46% of the HIV negative and 63% of the HIV positive subjects indicated reducing the number of sexual partners and/or using condoms.^ieng
