    Abstract:
    Our objective was to propose a strategy to screen HIV-infected African people for biological immunodeficiency easily. In a cross-sectional study, we analysed the patterns of diseases and of CD4 counts among 266 HIV-infected adults. Peripheral facial paralysis and chronic cutaneo-mucous diseases were the earlier B-stage diseases. Pulmonary tuberculosis was close to B-stage diseases, and chronic diarrhoea was borderline between B and C stages. Cachexia was the most frequent C-stage symptom (47.8%). Ninety per cent of CDC-C stage people had CD4 counts below 350/microliter, whereas only 75% had CD4 counts below 200/microliter. Regression analysis identified the lymphocyte count, clinical stage and platelet count as predictors of CD4 count below 350/microliter. A simple score (lymphocyte count < or = 2500/microliter and clinical stage > or = B) is proposed to determine this CD4 threshold (positive predictive value: 83%) and to determine those patients needing treatment to prevent wasting and opportunistic infections. Findings are presented from a cross-sectional study conducted in 1995 in Bobo-Dioulasso, Burkina Faso, in which the patterns of diseases and CD4 counts among 266 HIV-infected adults of mean age 33 years were analyzed. The bioclinical spectrum of subjects' HIV disease is described and a simple alternative proposed to CD4 enumeration for screening and monitoring HIV-infected Africans. Dermatological symptoms and diarrhea were the most frequent signs associated with B-stage disease, while cachexia and digestive candidosis were the most frequent AIDS-defining diseases (ADD). Peripheral facial paralysis and cutaneo-mucous diseases were associated with weak immune deficiency. Pulmonary tuberculosis (TB) was close to B-stage diseases, and chronic diarrhea was borderline between B and C stages. Cachexia was the most frequent C-stage symptom (47.8%). 90% of CDC C-stage subjects had CD4 counts of less than 350 per mcl, while only 75% had CD4 counts under 200/mcl. Regression analysis identified the lymphocyte count, clinical stage, and platelet count as predictors of CD4 count below 350/mcl. A lymphocyte count of less than or equal to 2500/mcl and clinical stage of B or higher is proposed to determine the CD4 threshold and to determine those patients in need of treatment to prevent wasting and opportunistic infections.
