Impact of G6PD deficiency on plasmodium falciparum malaria / 实用医学杂志

ABSTRACT

Objective To investigate the impact of Glucose-6-phosphate dehydrogenase (G6PD) deficiency on plasmodium falciparum malaria. Methods A cross-sectional study was performed on 2 690 patients in Malabo regional hospital on Bioko Island during rainy season (2012). The plasmodium falciparum was identified by real-time PCR and oil immersion microscopy. G6PD deficiency was identified by a fluorescent spot test (FST) and PCR-DNA sequencing. Logistic regression was conducted to estimate the association between G6PD deficiency and malaria. Results The prevalence of G6PD was 9.22% in the population , all of whose genotype G6PD deficiency was G6PD*A-(c.202 G > A/c.376 A > G). Confounding factors-adjusted OR showed that G6PD deficiency provided significant protection against malaria (P 0.05). Conclusions The results suggest that male hemizygotes could provide protection against malaria. Further studies are required to explore the molecular mechanism in malaria infection.
