Pediatric human immunodeficiency virus screening in an African district hospital.

In order to evaluate alternative tests and strategies to simplify pediatric human immunodeficiency virus (HIV) screening at the district hospital level, a cross-sectional exploratory study was organized in the Democratic Republic of the Congo. Venous and capillary phlebotomies were performed on 941 Congolese children, aged 1 month to 12 years (153 children under 18 months and 788 children more than 18 months old). The HIV prevalence rate was 4.

Evidence of stable HIV seroprevalences in selected populations in the Democratic Republic of the Congo.

Objective: To determine current data on HIV infection and to document changes and trends of HIV seroprevalence in selected populations over time in the Democratic Republic of the Congo (DRC; former Zaïre).

Methods: In February 1997, a large serosurvey was conducted on selected population groups from Kinshasa (capital city), Mbuji-May (southeast) and Bwamanda (northwest). Samples obtained from pregnant women, tuberculosis patients, commercial sex workers, blood donors and sexually transmitted disease patients were screened for the presence of HIV antibodies by a rapid assay and a commercial enzyme-linked immunosorbent assay.

Similar serological response to conventional therapy for syphilis among HIV-positive and HIV-negative women.

Objectives: To compare characteristics of syphilis serological reactivity in HIV positive (+) and HIV negative (-) female sex workers, as well as the serological response to therapy after treatment with intramuscular benzathine penicillin, 2.4 million U weekly, for three consecutive weeks.

Methods: Rapid plasma reagin (RPR) and Treponema pallidum haemagglutination assay (TPHA) results of 72 HIV-positive and 121 HIV-negative women reactive in both tests were assessed.

HIV and other sexually transmitted diseases among female prostitutes in Kinshasa.

In 1988, 1233 prostitutes from different geographic areas of Kinshasa participated in a cross-sectional survey on HIV infection and other sexually transmitted diseases (STDs). Despite relatively good knowledge about AIDS and STDs, the reported preventive behaviour was poor. Only 12% of the women reported regular use of condoms, while greater than 50% of the women reported regular use of antibiotics and 38% reported doing nothing specific to prevent STDs.

Detection of salivary HIV-1-specific IgG antibodies in high-risk populations in Zaire.

Saliva and blood samples were tested for human immunodeficiency virus-1 (HIV-1) antibodies in two high-risk populations in Kinshasa, Zaire. In a seroprevalence study of 458 sexually transmitted disease (STD) clinic attendees, 142 of 145 seropositive individuals had enzyme-linked immunosorbent assay (ELISA)-positive saliva samples (97.9% sensitivity).
