OBJECTIVE: To evaluate if an increase of TB correlated to HIV-2
infection occurs, and if there is an appearance of HIV-1 infection among
TB patients in a Country where the prevalent serotype is HIV-2. METHODS:
From August '91 to July '92 we studied 630 TB patients, 366 males
average age 42 y. (R 87.2) and 264 females average age 40 y (R 75-1)
with evaluation of HIV-2 and HIV-1 (ELISA and Western blot). RESULTS: In
the last 5 months of '91, 50 of the 260 pt. (19.23%) were HIV-2
positive, 2 (0.76%) were HIV-1 positive, and 1 showed also by W.B.
double reactivity. In the first 7 months of '92, 81 (21.9%) of the 370
studied were HIV-2 positive, 9 (2.43%) were HIV-1 positive and 7 (1.89%)
showed double reactivity by W.B. The overall HIV-2 and HIV-1
seroprevalence was 26%. CONCLUSIONS: The studies we made in 1990 showed
in TB patients and HIV-2 seroprevalence of 17.73% while in 1989 it was
of 14.8%. The epidemiological data which we possess show a substantial
stability in Guinea Bissau of new TB cases registered in 1990 (1153) and
1991 (1105) (unpublished), while there is an increase in seroprevalence
for HIV-2 and recently for HIV-1. Further longitudinal studies on this
patient's population are needed to determine the specific role of HIV-2
and HIV-1 in TB spreading and evolution.
