RESUMEN

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)

RESUMEN

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.

RESUMEN

To evaluate the possible effect of opiates on blood rheology, the plasma fibrinogen, prothrombin time and leukocyte aggregation were measured in 75 heroin addicts categorized by the time of abstention from heroin and the administration of naltrexone (25 active heroin abusers, 25 abstaining for 1 week, 11 abstaining for at least 5 months and 14 abstaining for 1 month and taking naltrexone during this period). No difference was detected in prothrombin time, but the leukocyte aggregation and fibrinogen were significantly different among the four groups (p = 0.028 and p = 0.0001, respectively). In particular, fibrinogen was 318 +/- 10.9 mg/dL in heroin abusers, significantly higher than that of the remaining three groups; the percentage of aggregated leukocytes was 5.01 +/- 0.77 in heroin users, significantly higher than that of subjects abstaining for at least 5 months. The fibrinogen levels declined sharply with abstention and an additive effect was noted with the administration of naltrexone, but leukocyte aggregation changed more slowly, and the effect of naltrexone (if any) was weaker. These data indicate an adverse effect of opiates on blood rheology and suggest that further studies should be performed to evaluate whether naltrexone may be useful in the prevention of major ischemic syndromes in patients with hyperfibrinogenemia and, perhaps, in those with high levels of leukocyte aggregation.

RESUMEN

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.

RESUMEN

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

RESUMEN

The results obtained in an investigation carried out on male alcoholics who had not drunk for three years are presented and evaluated. The research was carried out on a sample of 200 subjects aged between 30 and 50, average schooling, belonging to AA groups. The purposes of the study were to identify the psychopathological features of the sample in relation to the neurotic and psychotic aspects of the personality. A comparison was subsequently made with a similar female sample selected from a previous research. An abbreviated form of the MMPI test was used in the clinical part.
