AB OBJECTIVE. To compare times of progression to AIDS between I.V.D.U.'s
and homosexuals in a large cohort of symptomatic patients treated with
Zidovudine in Italy. METHODS. In a multicenter cohort study of 1495
patients undergoing ZDV treatment, enrolled by over 100 clinical centers
in Italy who prospectively followed the patients according to a protocol
schedule, the progression to AIDS is analyzed for two groups of
subjects: IVDU's (1120), and homosexuals (171) using Cox's proportional
hazard model. Enrollment started on July 1, 1987 and cutoff date for the
study was September 30, 1992. Mean follow-up time was three years.
RESULTS. Homosexuals showed a relative risk (RR) of progression to AIDS
30% higher than IVDU's, controlling for confounding variables, such as
baseline CD4+ count, ZDV dosage, calendar year of treatment beginning,
opportunistic infections and symptoms at enrollment. Other variables
associated with an earlier progression were CD4+ counts (RR increases by
39% for a decrease of 100 counts/mm3), age at enrollment (RR is 13%
higher for subjects 5 years older), ZDV dosage (RR increases by 26% for
high vs. low dosage). Among opportunistic infections at enrollment only
oral candidiasis (RR = 1.27) and fever (RR = 1.77) were found to be
associated to an early progression. The AIDS defining events were also
compared: Kaposi's sarcoma was the only event significantly different
between the two groups. When controlling for the AIDS defining events no
further difference in risk between the groups is found. CONCLUSIONS. The
increased risk for homosexuals is mostly explained by the presence of
Kaposi's sarcoma, as AIDS-defining event. Therefore, it is not possible
to assess whether the increased risk which appear to exist in
homosexuals as compared to IVDU's is due only to anticipated diagnosis
or to an actual increased risk for this category.
