In 1969 it was very difficult to explain the sudden unexpected appearance of some finely granulated large lymphoid cells that had been hidden in the human blood for over a full century, as they suddenly revealed themselves in our laboratory at M.D. Anderson Hospital, Houston TX. At first, the hematopathologists considered these cells to be of monocytoid (M) derivation; by accidental misprint, instead of monocytoid noted as “macrophagic” in the legends. These new cells appeared clearly distin...

Antiretroviral therapy (ART) has proved to be an important intervention in the reduction of both morbidity and mortality of HIV infected patients. As the use of ART increases, a number of studies have associate it to some metabolic complications including glucose intolerance, dyslipidaemia, and diabetes mellitus. Despite the high prevalence of HIV/AIDS in Africa and the recent increased access to Antiretroviral drugs, information on ART related insulin resistance and glucose metabolism in the Af...

Tuberculin skin testing (TST) response as a predictive tool for development of pulmonary tuberculosis (PT) in Human Immunodeficiency Virus type-1 (HIV-1) infected subjects, is likely to be more valuable at early stage of illness in order to adapt timely management strategy. Earlier reports on HIV-1 infected blood donors with history of oral iron intake and biochemical evidence of iron overload documented development of high incidence of PT on follow up. A group of HIV-1 infected asymptomatic blo...
