  1. CD4+T-cell number at the time of acquired immunodeficiency syndrome.

    Article - En anglais

    In this article, the authors adapt and extend the methodology of Phillips (Phillips et al.

    J Acquir Immune Defic Syndr 1992 ; 5 : 148-52) to estimate the distribution of CD4+T-cell number at the time of acquired immunodeficiency syndrome (AIDS) and to estimate the correlation between CD4+T-cell number at AIDS and CD4+T-cell number prior to human immunodeficiency virus infection.

    Using data from the Los Angeles portion of the Multicenter AIDS Cohort Study, the authors find that the median CD4+T-cell count at the time of AIDS is 67 cells/mm3 with a 95% confidence interval of 58-84.

    The 5th and 95th percentiles of the distribution are 8 and 284, respectively.

    The authors estimate the correlation between the CD4+T-cell number at the time of AIDS and the CD4+T-cell number prior to human immunodeficiency virus infection to be 0.71 with a 95% confidence interval of 0.21-0.94.

    This very high correlation is suggestive of biologic hypotheses concerning possible control of the circulating CD4+T-cell number.

    The high correlation can also be useful in determining when to start prophylactic treatment.
