AB OBJECTIVE: To study the slope of decline in CD4 cell counts and to
assess its relation to the risk of AIDS and age at seroconversion in a
hemophilia cohort followed for 14 years. METHODS: 158 hemophiliacs who
seroconverted to HIV between 1980 and 1985 were studied. The mean age
(SD) at seroconversion was 26.2(15.4) while the mean (SD) duration of
follow up time from seroconversion was 9.1(2.4) median 9.8. The slope of
decline in CD4 cells counts was calculated for 139 hemophiliacs who had
available at least 3 measurements of CD4 counts. RESULTS: The median
slope of change in CD4 counts with time in the different groups of
patients are shown: TABULAR DATA, SEE ABSTRACT VOLUME. Cox proportional
hazards analysis indicated that the slope of change in CD4 cells was
highly significant variable (p = 0.000) while the age at seroconversion
did not remain significant after controlling for slope (p = 0.182). The
increased decline of CD4 counts in the group with age < 10 years was
mainly due to the normal lymphocytosis observed in this age group.
Moreover, additional analysis suggested that the increased decline of
CD4 counts in this group, was not associated with faster progression to
AIDS. DISCUSSION AND CONCLUSIONS: The change of CD4 counts should be
considered as a candidate surrogate outcome of HIV infection in clinical
trials of asymptomatic individuals.
