Changes in the level of CD4-bearing T-lymphocytes in injection drug users infected with the human immunodeficiency virus were evaluated in a sample of 318 subjects enrolled from a methadone program in the Bronx, New York, from 1985 through 1989.
Follow-up continued through 1990.
The percentage of CD4+ T-lymphocytes (CD4%) was used to maximize the stability of measurements.
The rate of decline of the CD4% was determined using a random-effects assumption, and predictors of rate of decline were evaluated using an autoregressive model.
The rate of CD4% decline was approximately 1.2 CD4% lost per 6 months, with a higher rate in recent seroconverters (2.2 CD4% lost).
