Abstract

The study aims to determine the association of malaria infection with ABO blood groups and genotype and also to detect point mutations at positions 86, 184, 1034, and 1042 of the multidrug resistance gene in blood samples collected from pregnant women attending General Hospital Minna. Out of 250 pregnant women screened, 39 (15.60%) had malaria infection. Prevalence was higher in women, during the third trimester (46.15%), genotype AA (64.10%), and O blood group (53.84%) individuals when compared with others. There was significant ( < 0.05) decrease in Packed Cell Volume (PCV), hemoglobin (HGB), Red Blood Cells (RBC), and platelet (PLC) count in infected group when compared with noninfected group. Although, two of the isolates showed disrupted protein sequence at codon 1034-1042, no mutation was found in any of the isolates. Structural prediction of chemical ligand led to the identification of Neu5Ac2-3Gal1-3/1-4Glc/GlcNAc. This compound can theoretically bind and change the functional integrity of the pfmdr1 protein, thus providing a new window for malaria drug target.

摘要

该研究旨在确定疟疾感染与ABO血型及基因型之间的关联,并检测从明纳综合医院就诊的孕妇采集的血样中多药耐药基因第86、184、1034和1042位的点突变。在筛查的250名孕妇中,39名(15.60%)感染了疟疾。与其他情况相比,孕晚期女性(46.15%)、基因型AA个体(64.10%)和O血型个体(53.84%)的患病率更高。与未感染组相比,感染组的红细胞压积(PCV)、血红蛋白(HGB)、红细胞(RBC)和血小板(PLC)计数显著降低(<0.05)。尽管有两个分离株在密码子1034 - 1042处显示蛋白质序列中断,但在任何分离株中均未发现突变。化学配体的结构预测导致鉴定出Neu5Ac2 - 3Gal1 - 3/1 - 4Glc/GlcNAc。该化合物理论上可以结合并改变pfmdr1蛋白的功能完整性,从而为疟疾药物靶点提供了一个新的窗口。
