Assessment of the implementation of HIV-rapid test kits at different levels of health institutions in Ethiopia.

Objective: Evaluation and monitoring of Human Immunodeficiency Virus (HIV) testing reagents at the point of service is helpful to prevent the occurrence of problems related to testing and interpretation. To evaluate the implementation of HIV rapid test kits at the point of services in voluntarily counseling and testing (VCT) and diagnostic centers in Ethiopia.

Methods: The assessment was the third phase of evaluation of HIV rapid test kits in Ethiopia followed from phase-I and phase-II.

Prevalence and incidence of, and risk factors for, HIV-1 infection among factory workers in Ethiopia, 1997-2001.

The study was conducted to determine the prevalence, incidence, and risk factors for HIV infection among factory workers at two sites in Ethiopia. During February 1997-December 2001, a structured questionnaire was used for obtaining information on sociodemographics, sexual behaviour, and reported sexually transmitted infections (STIs) from a cohort of 1679 individuals. Serum samples were screened for antibodies against HIV, Treponema pallidum haemaglutination (TPHA), and herpes simplex virus type 2 (HSV-2).

Nine-year trends in HIV-1 prevalence among visa applicants in Urban Ethiopia.

A retrospective study was conducted to examine trends in HIV-1 prevalence among visa applicants between the years 1993 to 2001 in Urban Ethiopia. A total of 63,869 visa applicants were screened during these nine years period. The majority of them (79.

Performance of routine syphilis serology in the Ethiopian cohort on HIV/AIDS.

Objectives: To assess the performance of routine syphilis screening during 5 year follow up of Ethiopian factory workers, participating in a cohort study on HIV/AIDS.

Methods: Syphilis serology test results of factory workers, who each donated at least six blood samples were evaluated. Screening in 1997-8 had been performed by the Treponema pallidum particle agglutination (TPPA) assay and in 1999-2001 by the rapid plasma reagin (RPR) test.

Evaluation of rapid assays for screening and confirming HIV-1 infection in Ethiopia.

To evaluate a simple and rapid testing strategy to diagnose HIV infection in Ethiopia, we subjected a panel of 688 sera with known HIV serologic status (confirmed by ELISA/WB or double ELISA) to 3 rapid assays: Determine HIV-1/2, Capillus HIV-1/2 and Serocard HIV. Samples were obtained from participants in a cohort study on HIV-infection (72%), from tuberculosis patients (18%) and from participants in surveillance studies among police recruits and commercial sex workers (10%). The panel consisted of 249 HIV-1 positive samples, of which 68 were HIV-1 subtype C and 1 HIV-1 subtype A, and 439 HIV-1 negative samples.

Drug susceptibility of Neisseria isolates from patients attending clinics for sexually transmitted diseases in Addis Ababa.

Sixty eight Neisseria gonorrhoeae strains were isolated from endocervical and urethral discharge of 233 patients attending health centres for sexually transmitted diseases (STDs) in Addis Ababa, were identified following conventional procedures and tested for susceptibility to penicillin, ampicillin, trimethoprim-sulphamethoxazole (bactrim), chloramphenicol, erythromycin and kanamycin by the agar disc diffusion technique. Penicillinase producing N. gonorrhoeae (PPNG) were identified using the chromogenic cephalosporin method and comprised 70% of the isolates.
