    Abstract:
    Several observations have been made suggesting that excess iron is harmful to patients with HIV/AIDS disease. Bone marrow macrophage iron stores of 30 anaemic HIV infected patients (median age 32.7 years) and 20 anaemic AIDS-associated Kaposi's sarcoma patients (median age 37 years) were studied at the haematology department of the University of Maiduguri Teaching Hospital. Macrophage iron stores were assessed as either normal, decreased or increased by using grades ranging from 0 to 6. Marrow iron stores was increased in 16 (80%) of the patients with Kaposi's sarcoma and normal in 4 (20%) patients. Three of the 4 patients with normal iron stores were females of reproductive age. Regression analysis of iron status and opportunistic infection showed a positive correlation (p-value=0.001). Of the 30 patients with HIV infection, 22 (73.3%) had normal iron stores and 8 (26.7%) had decreased iron stores. All the 8 (26.7%) patients with no stainable iron in the marrow were females of reproductive age group. Iron deficiency anaemia can complicate anaemia of HIV infected patients. In view of the documented risk associated with iron supplementation in anaemic patients with HIV/AIDS disease, little caution should be exercise as regards the use of haematinics and/or blood tonics in anaemic HIV-infected or AIDS-associated Kaposi's sarcoma patients. The fact that noninvasive evaluation for iron deficiency is compromised in many individuals due to the presence of chronic inflammatory process and/or malignancy, bone marrow evaluation for iron stores still remains an important tool often underutilized by many clinicians attending to patients living with HIV/AIDS.
