title: Clinical and immunological follow-up of previously hospitalized HIV-2 seropositive patients in Bissau, Guinea-Bissau.
abstract: A follow-up study was done in Bissau on 113 HIV-2 seropositive patients and 97 HIV-2 seronegative patients 3-15 months after hospitalization. Follow-up totalled 63.5 person years for seropositive patients and 62 for seronegative patients. The mortality during the follow-up period was 43.3% among the seropositive patients (rate 72/100 person years; p.y.) and 25.8% among the seronegative patients (40/100 p. y.). Among 25 HIV-2 associated AIDS cases the mortality was 80% (rate 117/100 p. y.). The median survival time for the AIDS patients was 8 months. Among 48 HIV-2 seropositive patients who lacked signs or symptoms included in the WHO case definition for AIDS at the time of hospitalization 6 patients (12.5%) developed AIDS related symptoms (ARS) during altogether 31.5 person years of follow-up (rate 19/100 p. y.). Tuberculin anergy was demonstrated in 83.3% (15/18) of HIV-2 seropositive patients with AIDS or ARS, in 14.3% (6/42) of seropositive patients without HIV-related symptoms and in 6.9% (5/72) of seronegative patients. A low CD4 T-lymphocyte count in combination with a low CD4/CD8 T-cell ratio was found significantly more often in HIV-2 seropositive patients with AIDS or ARS (62.5%, 10/16) than in HIV-2 seropositive patients without HIV associated symptoms (6.9%, 2/29) or in seronegative patients (2.7%, 1/37). Thus the mortality among recently hospitalized HIV-2 seropositive patients was high and a high proportion of seropositive patients with HIV-related symptoms had evidence of immunodeficiency.
