MIST for respiratory distress syndrome management in moderate and late preterm infants was associated with a significant reduction of MV exposure and pneumothorax occurrence.

OBJECTIVES: To determine whether maternal supplementation with high-dose docosahexaenoic acid (DHA) in breastfed, very preterm neonates improves neurodevelopmental outcomes at 18 to 22 months’ corrected age (CA). METHODS: Planned follow-up of a randomized, double-blind, placebo-controlled, multicenter trial to compare neurodevelopmental outcomes in breastfed, preterm neonates born before 29 weeks’ gestational age (GA). Lactating mothers were randomized to receive either DHA-rich algae oil or a placebo within 72 hours of delivery until 36 weeks’ postmenstrual age. Neurodevelopmental outcomes were assessed with the Bayley Scales of Infant and Toddler Development third edition (Bayley-III) at 18 to 22 months’ CA. Planned subgroup analyses were conducted for GA (<27 vs ≥27 weeks’ gestation) and sex. RESULTS: Among the 528 children enrolled, 457 (86.6%) had outcomes available at 18 to 22 months’ CA (DHA, N = 234, placebo, N = 223). The mean differences in Bayley-III between children in the DHA and placebo groups were −0.07 (95% confidence interval [CI] −3.23 to 3.10, P = .97) for cognitive score, 2.36 (95% CI −1.14 to 5.87, P = .19) for language score, and 1.10 (95% CI −2.01 to 4.20, P = .49) for motor score. The association between treatment and the Bayley-III language score was modified by GA at birth (interaction P = .07). Neonates born <27 weeks’ gestation exposed to DHA performed better on the Bayley-III language score, compared with the placebo group (mean difference 5.06, 95% CI 0.08–10.03, P = .05). There was no interaction between treatment group and sex. CONCLUSIONS: Maternal DHA supplementation did not improve neurodevelopmental outcomes at 18 to 22 months’ CA in breastfed, preterm neonates, but subgroup analyses suggested a potential benefit for language in preterm neonates born before 27 weeks’ GA.

Unexpected severe cholestasis is part of the presentation in some neonates with hemolytic anemia but is usually self-resolving. Here we report the case of a neonate with pyruvate kinase deficiency (PKD) who presented severe hemolytic anemia at birth, characterized by a rapidly progressive and severe cholestasis with normal γ-glutamyl transpeptidase level associated with hepatic failure. After an extensive investigation to rule out contributing conditions explaining the severity of this patient’s clinical presentation, PKD has remained the sole identified etiology. The patient abruptly died of sepsis at 3 months of age before a planned splenectomy and ongoing evaluation for liver transplantation. To the best of our knowledge, only a few similar cases of severe neonatal presentation of PKD complicated with severe hepatic failure and cholestasis have been reported.
