BACKGROUND Clinical trials are increasingly being conducted internationally. In order to ensure enrollment of healthy participants and proper safety evaluation of vaccine candidates, established reference intervals for clinical tests are required in the target population. METHODOLOGY/PRINCIPAL FINDINGS We report a reference range study conducted in(More)
OBJECTIVE To describe clients, operation and impact of an African public HIV testing and counselling centre. DESIGN AND SETTING Analysis of samples from clients attending the AIDS Information Centre (AIC) in Kampala, Uganda in early 1991. SUBJECTS HIV-1-positive and HIV-negative consecutive clients (250 of each), 86 consecutive couples, and 200(More)
The use of rapid tests for human immunodeficiency virus (HIV) has become standard in HIV testing algorithms employed in resource-limited settings. We report an extensive HIV rapid test validation study conducted among Ugandan blood bank donors at low risk for HIV infection. The operational characteristics of four readily available commercial HIV rapid test(More)
BACKGROUND Screening donated blood for hepatitis C virus (HCV) is important for HCV prevention and is routinely practiced in North America and Europe. However, in many African countries little is known about HCV prevalence or cost-effectiveness of HCV antibody (anti-HCV) screening. METHODS We investigated 2592 plasma specimens collected consecutively from(More)
OBJECTIVES To assess the safety, tolerance, pharmacokinetics, and virologic and immunologic changes associated with the use of Ugandan HIV hyperimmune globulin (HIVIGLOB) in HIV infected pregnant Ugandan women and their infants. DESIGN A prospective, phase I/II, three-arm dose escalation trial of HIVIGLOB. METHODS HIVIGLOB was prepared from discarded(More)
Human herpesvirus 8 (HHV-8) is etiologically linked to Kaposi's sarcoma, a common cancer in Uganda. The authors assessed HHV-8 seroprevalence, risk factors for infection, and HHV-8 assays in a cross-sectional study of Ugandan blood donors. Of 3,736 specimens, the authors selected 203 reactive for HIV, hepatitis B surface antigen (HBsAg), or syphilis, and,(More)
OBJECTIVE To evaluate a manual method (Cytosphere) for quantifying CD4+ T-cell numbers. DESIGN Cross-sectional study of HIV-1-seronegative and HIV-1-seropositive individuals evaluated for absolute CD4 counts by both standardized flow cytometric measurements and manual Cytosphere technology using a hemacytometer. SETTING University research hospitals in(More)
Before commencing rational control programmes for AIDS in Africa it is desirable to determine the relative importance of heterosexual and various non-sexual modes of transmission. We investigated this by comparing the seroepidemiologies of AIDS, hepatitis B and syphilis at two rural hospitals in southwest Uganda. During August 1986, 3% of 357 outpatients,(More)
Sera were collected from 426 volunteers in Uganda at high and low risk for acquisition of hepatitis C virus (HCV). All samples were tested by the Ortho HCV second generation ELISA (S1) and by the INNOTEST HCV Ab second generation enzyme immunoassay, (S2), (Innogenetics, Antwerpen, Belgium). Sera that were repeatedly reactive by either screening assay were(More)
The third variable (V3) loop of the human immunodeficiency virus type 1 (HIV-1) envelope protein is an important determinant for virus neutralization and cell tropism. V3 loop sequences from uncultured lymphocytes obtained in 1990 from 22 Ugandan HIV-1-infected patients could, with the exception of two patients' sequences, be divided into two groups (A and(More)
