The respective mean (±SD) of hemoglobin level, RBC count, WBC count, platelet count, lymphocyte count and CD4+ T cell counts in malaria co-infected patients versus non-infected patients were: 10.8(±1.9) g/dl versus 11.4(±2.0)g/dl; 3,745,254(±793,353) cells/μl versus 3,888,966(±648,195) cells/μl; 4,403(±1,534) cells/μl versus 4,920(±1,922) cells/μl; 216,051(±93,884) cells/μl versus 226,792(±98,664) cells/μl; 1,846(±711) cells/μl versus 2,052(±845) cells/μl and 245(±195) cells/μl versus 301(±211) cells/μl. The gene discussed is CD4; the disease is malaria.
