Pediatric human immunodeficiency virus infection in a low seroprevalence area.
Although increasing information is available regarding human immunodeficiency virus (HIV) infections of children in high seroprevalence areas, few data are available describing trends in low seroprevalence populations. In San Diego County approximately 1 in 1450 live births are to women infected with HIV as identified by nonlinked heel stick testing. Seventy-seven HIV-infected children were identified and followed in our clinics during the period 1983 to 1991, of whom 32 (42%) were infected perinatally, 32 (42%) were hemophiliacs and 13 (17%) were infected by blood transfusions. During the last 4 years of the study period (1988 to 1991), most (28 of 37, 76%), newly identified HIV-infected children less than 13 years old were perinatally infected. Of the 32 perinatally infected children 50% were Hispanic, 34% were Caucasian and 16% were African-American. The prospective vertical transmission rate was 16%. Twenty-nine (38%) of the HIV-infected children have a diagnosis of acquired immunodeficiency syndrome and 17 (22%) have died. Comparatively few of the HIV-infected hemophiliac patients (4 (12%)) have progressed to an acquired immunodeficiency syndrome diagnosis. The number of acquired immunodeficiency syndrome diagnoses declined in the last 2 years of the study as a result of fewer cases of Pneumocystis carinii pneumonia; 11 cases of P. carinii pneumonia were diagnosed in 1988 to 1989 compared with 4 cases in 1990 to 1991. Survival analysis for the perinatally infected group yielded a median survival of 9.2 years. The apparent trend in our data toward improved outcomes of children infected with HIV suggests the beneficial effects of early identification, antiretroviral treatment, and P. carinii pneumonia prophylaxis.
