Predictors of HIV Serostatus among HIV Discordant Couples in Lusaka, Zambia and Female Antenatal Clinic Attendants in Kigali, Rwanda

Clinical manifestations of HIV disease in Africa are nonspecific and easily confused with other endemic diseases. Several studies have compared the prevalence of HIV-related signs and symptoms in infected versus uninfected populations, but little is known about differences in HIV disease manifestations between African men and women across geographic areas. We conducted a cross-sectional study to define predictors of HIV status and assess their differences by gender and country in two African cohorts: 1351 heterosexual couples recruited from a voluntary HIV counseling and testing center in Lusaka, Zambia, and 1458 women recruited from antenatal and pediatric clinics in Kigali, Rwanda. HIV-positive Zambian men and women differed most with respect to prevalence of wasting syndrome (48.1% vs. 35.5%, p < 0.01). Zambian women were more likely to have a disseminated adenopathy than Rwandan women (33.2% vs. 7.8%, p < 0.01) and had a much higher median erythrocyte sedimentation rate (ESR) than either of the two ot...
