Abstract:
Objective:To study the clinical characteristics and differences of severe hyperbilirubinemia caused by hemolytic disease of the newborn (HDN) and glucose-6-phosphate dehydrogenase (G6PD) deficiency.Methods:From January 2014 to December 2021, newborns (gestational age ≥ 35 weeks and postnatal age ≤ 28 d) admitted to the Department of Neonatology of Hunan Children's Hospital with severe hyperbilirubinemia caused by HDN or G6PD deficiency were retrospectively analyzed. According to the etiology of hyperbilirubinemia, they were assigned into HDN group and G6PD deficiency group. The general conditions, clinical manifestations, laboratory results, treatment and prognosis of the two groups were compared using SPSS 26.0 software.Results:A total of 532 cases were in the HDN group and 413 cases in the G6PD deficiency group. The HDN group reached peak hyperbilirubinemia earlier than the G6PD deficiency group [3(2,5) d vs. 6(4,8)d, P<0.05]. The HDN group had lower peak value of total serum bilirubin [379.5(345.6,426.7) μmol/L vs. 486.4 (413.5,577.4) μmol/L] and lower incidence of anemia [37.4% (199/532) vs. 55.0% (227/413)]than the G6PD deficiency group.The incidence of anemia with elevated reticulocyte percent(Ret%) in the HDN group was higher than the G6PD deficiency group[66.3%(132/199) vs. 5.7%(13/227), P<0.05]. Compared with the G6PD deficiency group, the incidences of exchange transfusion and repeated (≥2 times) exchange transfusion, acute bilirubin encephalopathy(ABE) and the mortality rate after withdrawal of treatment in the HDN group were significantly lower ( P<0.05). Conclusions:Neonatal severe hyperbilirubinemia caused by HDN has early onset. G6PD deficiency caused hyperbilirubinemia has higher incidences of anemia, more severe jaundice and ABE, without increased Ret%.
