Haematologic Indices in Pulmonary Tuberculosis with or without HIV Co-Infection in South Eastern Nigeria



To evaluate the changes in haematologic indices in patients with pulmonary tuberculosis (PTB) with or without Human Immune Deficiency Virus (HIV) co-infection in South Eastern Nigeria. The study population included 116 subjects (60 = males; 56 = females), recruited from 2 study centers: mile 4 Hospital Abakaliki Ebonyi State and Nnamdi Azikiwe University, Teaching  Hospital Nnewi, Anambra State, both in Nigeria. PTB + HIV (n = 20); PTB infection ( n = 27) and HIV sereopositive (n = 28). The PTB and HIV negative; control subjects were 41 (n = 41). Blood samples collected from subjects in Ethylene diamine tetra acetic acid (EDTA) container were used for the analysis of the Haemtological cells count,  packed cell volume (PCV) and Haemoglobin estimation using routine methods as described (Dacie and Lewis, 1984). HIV screening was done with Stat pak kit and confirmatory test by Western blot method. Erythrocyte sedimentation rate (ESR) was by Westergren method. Haemoglobin estimation (Hb), packed cell volume (PCV) values were significantly lower in patients with PTB (11.27±1.62 g/dl, 0.35±0.04 l/l) compared with control values (13.67±1.46 g/dl 0.41 ± 0.05 l/l) (p < 0.05). Patients with HIV seropositive showed significantly low PCV values of (0.36 ± 0.04 l/l) compared with the control subjects (0.41 ± 0.05 l/l) (p < 0.05). PTB patients showed higher TWBC counts (6062.5 ± 1481.83109/l) when compared those with HIV infection (3841.38±735.58 x 109/l) as well as normal control value (4363.64±551.66 x 109/l) (p < 0.05). Male and female values compared in this work showed no significant difference (p > 0.05). The results showed that the effect of PTB and HIV infection have caused some haematological deregulation. It also showed that sex has little or no effect on the studied parameters.
