BackgroundA high proportion of individuals receiving highly active antiretroviral treatment (HAART) complain of sexual dysfunction (SD), encompassing a lack of desire or erectile dysfunction. ObjectiveTo determine whether SD was associated with particular components of the HAART regimens and to identify risk factors for the development of SD in patients on HAART. MethodsA survey among patients with HIV infection using an anonymous questionnaire was conducted in 10 European countries between December 1998 and December 1999. A total of 904 individuals currently receiving antiretroviral agents were included in the analyses. ResultsA decrease in sexual interest was significantly more frequently reported by subjects (men and women) using HAART containing protease inhibitors (PI) (308/766, 40%), compared with PI-naive patients (22/138, 16%; OR 3.55; 95% CI 2.15–5.89). In addition, a significantly larger number of PI-experienced men reported a decrease in sexual potency (216/628, 34%) compared with PI-naive men (12/99, 12%; OR 2.56; 95% CI 1.33–5.03). In multivariate analyses the following factors were associated with a decrease in sexual interest: a current PI-containing regimen, a history of a PI regimen, symptomatic HIV infection, age and homosexual contact as HIV transmission mode. Factors associated with a decrease in sexual potency were: current use of a PI-containing regimen, symptomatic HIV disease, age and the use of tranquillisers. ConclusionSD appears to be a common side-effect of HAART regimens containing a PI. The potential association between SD and other side-effects of HAART, such as lipodystrophy syndrome and neuropathy, should be investigated further.

Between June 1996-September 1997 and December 1998-December 1999, two surveys using an anonymous questionnaire were carried out in Europe among persons living with HIV infection. The questionnaire included questions on use of antiretrovirals, complementary or alternative medicines. Vitamins/minerals were taken by 528 (58%) of the 1996-97 participants, compared to 326 (63%) of the 1998-99 participants (P =0.06). Homeopathy was taken by respectively 176 (21%) and 55 (14%) (P =0.003) participants and herbal products respectively by 213 (25%) and 77 (20%) (P =0.06). In multiple regression analysis a longer time since HIV diagnosis, having a higher education level and having a lower CD+ lymphocyte count were associated with the use of homeopathy. A longer time since HIV diagnosis and a more advanced stage of the disease were associated with the use of herbal products. The study shows that despite the availability of highly active antiretroviral therapy many people with HIV infection still take complementary and alternative medicine.

Objective: To identify risk factors for the development of lipodystrophy in HIV infected patients on highly active antiretroviral therapy. Methods: A survey among patients with HIV infection using an anonymous questionnaire was conducted in 10 European countries between December 1998 and December 1999. Nine hundred and four people receiving antiretrovirals, were included in the analyses. Results: 368 (41%) people reported an increase in abdominal girth since commencing current antiretroviral treatment. Breast enlargement was reported by 106 people (12%). Lipoatrophy signs were reported by approximately one-third of the people: 291 (32%) complained about decrease in facial fat and 300 (33%) reported decrease in buttock fat. One hundred and thirty-one (15%) people reported both lipoatrophy signs and an increase in abdominal girth (mixed lipodystrophy syndrome). In multivariate analysis, the development of the mixed lipodystrophy syndrome was associated with a longer use of indinavir (OR=1.03, 95% CI: 1.00–1.06), ritonavir (OR=1.06, 1.02–1.09) and stavudine (OR=1.05, 1.02–1.08) and also with age, a longer duration of HIV seropositivity and an advanced stage of HIV infection. Conclusions: This study suggests that multiple factors are associated with the occurrence of lipodystrophy, including the prolonged use of protease inhibitors.

Our objective was to compare the utilization of healthcare/support services for people with HIV infection in Europe. Between August 1996 and September 1997 self-administered anonymous questionnaires were distributed by reference HIV treatment centres and HIV support organizations. The questionnaire was completed by 1366 people living with HIV/AIDS. A small number of people had received influenza or pneumococcal vaccinations (34% and 19% respectively). Many patients did not receive dental care (48% of participants from the southern countries) and only 72% of the women had a gynaecological examination. More participants from the south reported insufficient access to healthcare/support services, particularly for nursing care (19%), psychological support (33%), nutritional advice (45%), access to support organizations (36%), and legal advice (46%). In conclusion, many people living with HIV/AIDS in Europe do not benefit from certain annual medical procedures proposed by international guidelines and consider themselves to have insufficient access to health/support services.
