BACKGROUND: Hematological changes involving all blood cells are some of the most common complications in both tuberculosis (TB) and malaria infection. The changes induced by malaria infection are diverse, and the first line anti-TB treatment regimen which involves two phases may alter these changes in TB participants co-infected with malaria (TB/MP). OBJECTIVE: In this study, we aimed to ascertain the impact of malaria co-infection on leukocyte indices of TB-infected participants at pre-treatment, intensive and continuation phase therapy. MATERIALS AND METHODS: In this cross-sectional study, 180 participants were recruited comprising; 60 (35 TB and 25 TB malaria) participants before treatment, sixty (36 TB and 24 TB-Malaria) participants after intensive phase treatment and sixty (27 TB and 33 TB-Malaria) participants after continuation phase therapy. Whole blood was used for the measurement of total (total white blood cell [TWBC]) and differential white cell count, Platelet count, and packed cell volume (PCV). RESULTS: Before initiation of treatment, TWBC, neutrophil, lymphocyte, platelet count, and neutrophil-lymphocyte ratio were significantly reduced (P = 0.041, 0.022, 0.046, and 0.026, respectively), whereas eosinophil count was significantly increased in TB/Malaria participants compared to TB participants (P = 0.043). There was no significant change in these parameters after intensive phase treatment (P > 0.05). However, after continuation phase treatment, PCV was significantly reduced, while eosinophil was significantly increased in TB/Malaria participants compared with TB participants (P = 0.046 and 0.045, respectively). CONCLUSION: Malaria co-infection induces the significant reduction in leukocyte indices of TB patients at pretreatment but not at the intensive and continuation phase anti-TB therapy except eosinophils count which was increased before treatment and continuation phase treatment.
