摘要:
During 11 months in 1989–1990, 1009 consecutive hospitalized adult patients admitted to the medical wards of the National Hospital in Bissau were interviewed, examined clinically, and tested for antibodies to HIV-1 and HIV-2. The prevalence of HIV-2 infection was 20.4% (206 out of 1009) and of HIV-2-associated AIDS 4.4% (44 out of 1009). HIV-2 infection was more frequent in women (25%, 110 out of 440) than in men (16.9%, 96 out of 569). HIV-1 infection was diagnosed in one patient only, and one patient (with AIDS) had reactivity to both HIV-1 and HIV-2. Among HIV-2-seropositive patients, AIDS was demonstrated in 21.3% and AIDS-related symptoms (not fulfilling the AIDS criteria) in 19.4%. The frequency of AIDS-associated symptoms was significantly higher in HIV-2-seropositive patients than in seronegative patients. The clinical profile of the HIV-2-associated AIDS cases was very similar to that described in HIV-1-associated AIDS cases in Africa. Seven out of 51 patients fulfilling the clinical criteria for AIDS were HIV-seronegative. The World Health Organization (WHO) clinical case definition for AIDS in Africa had a specificity of 99% and a positive predictive value of 86%. Tuberculosis was more common in HIV-2-seropositive patients (6.3%) than in HIV-2-seronegative patients (2.2%). A history of blood transfusion was a significant risk factor for HIV-2 infection. HIV-2 infection and AIDS are public health problems in Guinea-Bissau.
