Background: Acute bilirubin encephalopathy (ABE) still represents a significant cause of morbidity and mortality throughout the world, especially in developing countries. We aimed to determine the prevalence of ABE based on the Johnson bilirubin-induced neurologic dysfunction (BIND) score and to describe the discharge outcomes.
Methods: We prospectively studied all newborns ¡Ý 35 weeks with ABE by evaluating signs of mental sensorium, muscle tone, and cry patterns over 1 year.
Results: 12% (81 out of 674) of the newborns admitted for neonatal hyperbilirubinemia had a BIND score > 1. Their admission age was 6 ¡À 4.1 days; total serum bilirubin (TSB) was 31.2 ¡À 10 mg/dL (range 17.5-75.2). Of these newborns, 40.7% and 21% had evidence of haemolysis and sepsis, respectively. Overall mortality was 9.9%; 58% of the newborns showed signs of mild-to-moderate BIND at discharge, while 32.1% survived with an apparently normal outcome. Admission BIND score was significantly correlated with admission TSB (r = 0.476, P < 0.001). Similarly, BIND score at discharge was correlated with admission TSB (r = 0.442, P < 0.001) and admission BIND score (r = 0.888, P < 0.001). The regression model showed that admission TSB (P < 0.001) and maternal illiteracy (P = 0.034) were predictors of the BIND score at admission, while admission BIND score was the best indicator of the discharge score (P < 0.001). Conclusions: ABE is still a major problem in our community. Admission TSB and maternal illiteracy are good predictors of bilirubin encephalopathy at admission and discharge.
