Epidemiological factors related to slow progression of the acquired immune deficiency syndrome (AIDS)

Abstract

To determine the factors involved in slow progression to aids, a transverse study was conducted for the evaluation of the epidemiological data of individuals infected with type 1 human immunodeficiency virus seen at the University Hospital of the Faculty of Medicine of Ribeirão Preto-USP. Patients were choosed in conformity some judgment, establish two populations: population 1, consisting of slow progressors (P1), had been carrying HIV antibodies for more than 8 years, with the occurrence of less than 2 opportunistic diseases in the last year, and population 2 (P2), consisting of rapid progressors, had a diagnosis of HIV infection and overt disease detected less than 2 years before and more than 2 opportunistic diseases diagnosed during the last year. All patients responded to a questionnaire concerning demographic data, profession, occurrence of other sexually transmissible diseases, form of contagion, date of diagnosis, and habits. The study was conducted from March 1998 to October 1999. We obtain in the P1: 12 men and 4 women, mean age 30.7 years, predominant form of contagion: blood route, time of disease progression 10.5 years; P2 12 men and 4 women; mean age 34,8 years, predominant form of contagion: sexual, time of disease progression 1.5 years. Tabagisme was the principal vice in about populations. When asked about motivation yours good health, the subjects of P1 answered to be relationed the faith and medications use. The patients of the P2 did not answer about yours health state. Whatever the sexual custom, 9 patients of the P1 had sexual relations, five without regular use of condom. In the P2 only um patient used condom. Two patients of the P1 and one of P2 declared to have STD, syphilis and Human Papiloma Virus (HPV). Because there are reduces number of patients it’s impossible to make asociation between the variables studies and mesures of the disease progression. The dates about habits don’t contribute for the disease development. The study offers an epidemiological profile of these patient populations.
