- W4366998791 abstract "Abstract Background: Malaria is a life-threatening parasitic disease typically transmitted through the bite of an infected Anopheles mosquito. There is ample evidence showing the potential of malaria infection to affect the counts of lymphocyte subpopulations in the peripheral blood, but the extent of alteration might not be consistent in all geographical locations, due to several local factors. Although Ghana is among the malaria endemic countries, there is currently no available data on the level of alterations that occur in the counts of lymphocyte subpopulations during Plasmodium falciparum malaria infection among adults. Aim: The study was to determine the immunophenotypic alterations in the level of peripheral blood lymphocytes and their subsets in adults with uncomplicated P. falciparum malaria infection and apparently healthy participants. Methods: The study was a cross-sectional comparative study conducted in two municipalities of the Volta region of Ghana. Blood samples were collected from study participants and taken through serology ( P. falciparum /Pan Rapid Diagnostic Kits), microscopy (Thick and thin blood films) and Haematological (Flow cytometric and Full blood count) analysis. Results: A total of 414 participants, comprising 214 patients with malaria (cases) and 200 apparently healthy individuals (controls) were recruited into this study. Parasite density of the malaria patients ranged from 75/µL to 84,364/µL, with a mean of 3,520/µL. It was also observed that the total lymphocytes slightly decreased in the P. falciparum infected individuals (Mean ± SD: 2.08 ± 4.93 × 10 9 /L) compared to the control group (Mean ± SD: 2.47 ± 0.80 × 10 9 /L). Again, there was a significant medium positive correlation between parasite density and haematocrit levels (r= 0.321, p < 0.001). Apart from CD45+ T-cells, more people in the control group had normal values for the lymphocyte subsets measured compared to the cases. Conclusions: From the results obtained, there was high parasite density among the malaria patients suggestive of high intensity of infection in the case group. The cases again showed considerable haematological alterations in lymphocyte sub-sets and the parasite density appeared to be strongly associated with CD4+ T-cell reduction. Also, the parasite density significantly associated with decreasing haematocrit levels." @default.
