Abstract
Reticulocytes are immature red blood cells (RBCs) and they often serve as the indicators of bone marrow function. The fraction of reticulocytes in the blood depends on the clinical situation and the haemopoietic competence of the bone marrow. Circulating reticulocytes are decreased in patients with impairment of bone marrow function and increased in patients with blood loss as well as in cases of RBC destruction, with bone marrow activity. Although a human immunodeficiency virus (HIV) infected patient may have peripheral blood cytopenia, only patients in the advanced stage of the disease and or those with low CD4+ cell count is more likely to have this condition. This study aimed at assessing the reticulocyte count of HIV positive patients on highly active antiretroviral therapy (HAART) and those of non-HIV positive patients. 100 HIV positive patients between the ages of 10 years and 70 years were recruited as subjects while 40 apparently healthy HIV-negative persons served as control. Reticulocyte count was assessed using the manual method, staining with new methylene blue (light microscopy). Our findings showed that there were more female HIV positive patients in Ilorin, Kwara State, Nigeria and they had a mean reticulocyte count within the normal range along with a decreased viral load. Significant increase of reticulocyte count in HIV infection was seen in most females, particularly within the age range of 31-40, when compared with their male counterparts, otherwise there was no significant difference between the reticulocyte count of subjects and the control. A significant negative correlation was found between the reticulocyte count and viral load (R= -0.077, p=0.000) of the patients. The administration of specific HAART in HIV patients in our study had a notable improvement in the CD4+ cell count and the viral load with significant age and gender disparity. Females not placed on HAART are more likely to succumb to poor erythropoietic activity than their male counterparts.
