OBJECTIVE: To establish newborn screening in Indian scenario that could lay a framework for future such initiatives. Three disorders namely, congenital hypothyroidism (CH), congenital adrenal hyperplasia (CAH) and glucose-6-phosphate dehydrogenase deficiency (G-6-PDD) were selected for a preliminary study for newborn screening.
METHODS: Heel-prick blood samples were collected from live-born neonates at 24-48 h of birth as a part of a screening program after prior written consent from the parents. Blood levels of glucose-6-phosphate-dehydrogenase enzyme (G-6-PD), thyroid-stimulating hormone (TSH) and 17-α-OH progesterone (17-OHP) were measured using DELFIA time resolved fluoroimmunoassay.
RESULTS: Six thousand eight hundred and thirteen (6,813) neonates (86.3%), out of a total of 7,893 live births in our institute during the period May'2007 through July'2009, were screened for CAH, CH and G6PD deficiency. Major reason for missing samples was early discharge of the neonates and admission to the neonatal intensive care unit. G-6-PD deficiency was confirmed in 61 cases, congenital hypothyroidism (CH) in 2 cases and congenital adrenal hyperplasia (CAH) in 1 neonate, accounting for an incidence of 1/112 for G-6-PDD, 1/ 3400 for CH and 1/6813 for CAH.
CONCLUSIONS: Preliminary data on prevalence of various genetic disorders viz. G-6-PDD, CH and CAH in the population of this region revealed that G-6-PDD is most prevalent disorder followed by CH and CAH. More efforts need to be undertaken to create awareness and emphasis on significance of preventive testing to make screening a successful program in India.
