ABSTRACT
Serial CD4 lymphocyte counts were recorded in 112 anti-HIV-positive haemophiliacs who were followed for up to 8 years after seroconversion. The patients remained at low risk of developing AIDS until their CD4 lymphocyte count fell to 0.25 X 10(9)/l. From this point, the risk increased as their count approached zero. Using this result and on the assumption (which is evaluated) that the underlying trend over time in CD4 lymphocyte counts is linear, the predicted rate of progression to AIDS was calculated for the cohort. It was estimated that 73% (95% confidence limits 60-86%) of the cohort will develop AIDS within 15 years of HIV-seropositivity. During 8 years of follow-up, this cohort had shown similar rates of progression to AIDS to other cohorts--haemophilic and otherwise--suggesting that this estimate may well have general applicability. The method described could be used to plan the provision of health-care resources for groups of anti-HIV-positive patients as it allows the number of new cases of AIDS to be predicted year by year, even when the patients' dates of seroconversion are unknown.
