The use of complementary and alternative medicine by persons with HIV infection in Europe.

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.
