Prevalence of glucose 6 phosphate dehydrogenase (G6PD) deficiency in a community by newborn screening

Abstract

Background: Glucose 6 phosphate dehydrogenase deficiency is a genetic disorder and incidence 400 million per year globally. It is X-linked inherited disorder affect males and rarely females also by lyonisation. Characterized by significant biochemical and molecular heterogeneity. Known for its grave complications like hemolysis, severe anemia, failure and severe jaundice following ingestion of fava beans and certain drugs. Prevalent in certain communities of India, hence routine newborn screening and Detection of g6pd deficiency is important to prevent grave complications.Methods: Prospective observational study carried out at Vani Vilas Children’s hospital attached Bangalore Medical college and research institute, from January 2016 to September 2016. All the newborns born at Vani Vilas Hospial included in the study by routine newborn screening.Results: A total of 9,136 neonates were included in this study. There were 5,013 males and 4,123 females. 37 neonates were found to be G-6-PD deficient, prevalence being 0.40%. The difference in the prevalence of G-6-PD deficiency in males 0.57% (n=29) and females 0.19% (n=8) was significant (p <0.002).Conclusions: Significant prevalence of g6pd in India. In our study, we found 1 G6PD deficiency in per 1000 population. Hence, we recommend screening for G6PD deficiency in all the newborns to prevent complications in future.
