Reasons given by patients for 'non-progression' in HIV infection

Abstract

Identification of the reasons for long-term survival in HIV infection is an area of current intense research. The objective of this study was to determine the perceptions among patients with different rates of disease progression as to the reasons for a good outcome with HIV. In a case-control study of 134 long-term ( 8 years) HIV-infected participants, 62 were defined as non-progressors: 6 current CD4 cell count 500 10 /L and asymptomatic or only mildly symptomatic. Two groups of control patients were identified: intermediate progressors who also had been HIV-infected for 8 6 years, but whose current CD4 cell count was 500 10 /L (n= 61), and a group of rapid progressors who had developed AIDS within 5 years of HIV infection (n= 11). Non-progressors were asked 'what do you feel are the reasons for your good outcome with HIV-infection?' and intermediate and rapid progressors were asked 'what do you feel are the reasons for a good outcome with HIV infection?'. Mental attitude, and in particular a positive outlook was the reason most frequently given for a good outcome among both non-progressors (NP) 42%, and progressors (P) 40%, followed by lifestyle measures and personal action (NP 31%, P 35%). Medical treatments such as anti-retroviral drugs were rarely suggested ( 3%). No significant differences were observed in the frequency of the different reasons given by non-progressors and progressors. The belief among our long-term HIVinfected individuals, that a positive outlook, lifestyle and personal action are important determinants of a good prognosis, is in sharp contrast to the biomedical model of disease progression that prevails among the medical and scientific research community.
