A study of the hematological profile of human immunodeficiency virus positive patients in coastal South Indian region

Introduction: In India, approximately 6 million populations are affected by human immunodeficiency virus (HIV). Anemia and leukopenia, especially thrombocytopenia is seen commonly in HIV infections. Low CD4+ count and increased viral load are some of the factors associated with increased risk of thrombocytopenia. We analyzed the hematological profile in a group of 150 HIV infected patients. Materials and Methods: A retrospective and prospective study of medical records of 150 HIV positive patients at Clinical Pathology laboratory at our institution was done between August 1 st and October 15 th, 2011 using nonrandom sampling. Hemoglobin (Hb), hematocrit, red cell indices, total leukocyte and differential count, CD4+ and platelet count were noted. Results: Of the 150 patients, 40 (26.67%) were below age 10 and 98 (65.33%) in 21-50 years age group. Eighty-six (57.33%) were females. Hundred patients had anemia (Hb <12 g/dl) of which 58% were microcytic hypochromic (MCHC). Eighteen patients had leukopenia along with anemia. Total number of patients with low CD4 count (<200/μL) was 32 (21.33%) and all had hematological abnormalities, mostly anemias with few leukopenia and thrombocytopenias. All patients with pancytopenia had low CD4+ counts. Total number of patients with thrombocytopenia (<1.5 lacs/dl) was 20 (13.33%). Four patients (2.67%) had pancytopenia. Conclusions: MCHC anemia is the most common morphological variant of anemia. Leukopenia was found to be consistently associated with anemia. Thus, anemia and to a greater extent leukopenia are bad prognostic indicators of disease. Pancytopenia may herald a low CD4+ count.
