Hyperbilirubinemia management in neonates <2000 g screened for glucose-6-phosphate dehydrogenase deficiency in a tertiary neonatal unit

Abstract

Background: Prematurity and glucose-6-phosphate dehydrogenase (G6PD) deficiency are considered important risk factors in neonatal hyperbilirubinemia. G6PD screening is performed by many neonatal units to identify this risk factor. Few studies evaluated the role of this screening on the management of hyperbilirubinemia in preterm infants during their neonatal hospitalization. This study aims to evaluate effects of G6PD screening on treatment of hyperbilirubinemia in infants <2000 g admitted to Neonatal Intensive Care Unit. Methods: All neonates <2000 g who were admitted to neonatal unit for 3 years (2013–2015) were retrospectively included in the study. Data related to risk factors and management of hyperbilirubinemia were collected and analyzed on these infants. A number of phototherapy units used for treatment, duration phototherapy, and level of bilirubin were compared between G6PD deficient and nondeficient infants and presented. Results: Included in this retrospective study were 621 infants. About half on included infants were < 1500 g. Gestational age groups as follow: ≤28 weeks, 23.3%; 29–32 weeks, 37.5%; 33–36 weeks, 33.6%; and ≥37 weeks, 5.6%. Prevalence of G6PD deficiency was 10.3%. The highest recorded serum bilirubin was significantly higher in G6PD deficient group compared with nondeficient one (161.6 μmol/l ± 57.5 vs. 145.4 μmol/l ± 46.4, P = 0.01). G6PD deficient infants were treated with more phototherapy than nondeficient group (85.9% vs. 64.5%, P < 0.001). G6PD deficient low birth weight neonates were more likely to receive intensive phototherapy. None of the G6PD deficient patients was treated with exchange transfusion. Conclusion: Prevalence of G6PD deficiency among low birth weight infant in the United Arab Emirates is similar to data reported in full-term infants. Screening for G6PD in preterm infant is associated with more treatment using phototherapy and may contribute in preventing severe hyperbilirubinemia.
