AB OBJECTIVE: To examine the effect of adding new criteria (NEW) [severe
immunosuppression (SI) < 200 CD4+ cells/microL, CD4+ < 14%, pulmonary
TB, recurrent pneumonia, and invasive cervical cancer] on January 1,
1993 to the pre-1993 (OLD) AIDS reporting criteria. METHODS: We compared
NEW AIDS cases with OLD cases reported in 1993 and 1992. For diagnosis
dates (DX), data were adjusted for reporting delay; for SI cases, OLD
AIDS DX were estimated using data from a clinic-based study of 23,000
HIV-infected persons. RESULTS: Of the 103,500 AIDS cases reported in
1993; 55,432 (54%) were NEW cases and 48,068 were OLD cases; 91% of NEW
cases were SI cases. From 1992 to 1993, reporting increased 111%
overall, 152% in women vs. 105% in men, 123% in blacks vs. 102% in
whites, 214% in 13-19 y.o. vs. 112% in 30-39 y.o., and 136% in injecting
drug users (IDU) vs. 87% in homo/bisexual men. Persons with NEW AIDS
were more likely than those with OLD to be women (17% vs. 15%), black
(37% vs. 35%), IDU (29% vs. 26%), and living (88% vs. 66%), and to have
higher CD4+ values (121 cells/microL vs. 44). Of the 5,371 persons with
NEW opportunistic illnesses, 26% were women, 63% black, and 48% were
IDU. Trends in diagnosis were as follows. TABULAR DATA, SEE ABSTRACT
VOLUME DISCUSSION: The expanded definition has increased AIDS reporting,
includes persons in earlier stages of HIV disease, and better
characterizes persons with HIV-related SI and disease. Estimates of AIDS
DX trends must take into account the addition of SI reporting.
