Postnatal Steroids Use for Bronchopulmonary Dysplasia in a Quaternary Care NICU.

OBJECTIVE: Intercenter variation and trends in postnatal steroids (PNS) use among preterm infants for prevention or treatment of bronchopulmonary dysplasia (BPD) is known. Understanding intracenter PNS use patterns facilitate implementation of center-specific change interventions to optimize outcomes.This study aimed to (i) quantify the proportion of infants who received PNS, and describe the timing, type, trends over time, regimen used, and deviations, and (2) describe the clinical characteristics and unadjusted outcomes of infants who received PNS. STUDY DESIGN: This was a cohort study in a quaternary neonatal intensive care unit including infants born at less than 33 weeks, and who received PNS for prevention or treatment of BPD between 2011 and 2021. Following data were included: proportion of babies who received PNS; type of PNS; age at initiation and duration; trends over time; deviation from published regimen; morbidity, mortality, and cointerventions. RESULTS: One hundred and eighty four infants (8% of <33 week' infants) received PNS. The median (interquartile range [IQR]) gestational age and birth weight were 25 (24-26) weeks and 720 (625-841) grams, respectively. The median (IQR) day of initiation and duration of PNS use were 29 (19-38) and 10 (10-22) days, respectively. One hundred and fifty-seven (85%) infants received dexamethasone (DX) and 22 (12%) received hydrocortisone as the first PNS course, and 71 (39%) infants received multiple courses. The proportion of infants receiving PNS remained unchanged, but the cumulative median dose received for BPD per patient increased by 56%. Nearly one-third of cumulative PNS dose came from PNS used for non-BPD indications. Forty-six percent infants had a deviation from published regimen (±20% deviation in duration or ±10% deviation in dose). Survival, survival without major morbidity, moderate-to-severe BPD, and technology dependence at discharge were 87, 2, 91, and 67%, respectively. CONCLUSION: Increased variation in PNS use, deviation from published regimen, and concurrent PNS exposure from non-BPD indication offer insights into implementing interventions to improve processes. KEY POINTS: · In this quaternary NICU, 8% of infants born before 33 weeks were administered postnatal steroids (PNS).. · The percentage of infants given PNS remained stable; however, the cumulative dose per patient for BPD rose.. · The study identified targeted interventions to minimize clinical practice variations at the center..

Association of delayed cord clamping with acute kidney injury and two-year kidney outcomes in extremely premature neonates: a secondary analysis of the Preterm Erythropoietin Neuroprotection Trial (PENUT).

Background: Delayed cord clamping (DCC) occurs in most preterm births. Objective: Evaluate the association of DCC with acute kidney injury (AKI) and two-year kidney outcomes. Methods: Secondary analysis of the Preterm Erythropoietin Neuroprotection Trial of neonates born 240/7 to 276/7 weeks' gestation. AKI and two year kidney outcomes were compared in neonates with DCC (≥30 seconds after delivery) to those with early cord clamping (ECC) (<30 seconds after delivery). Results: The incidence and severity of AKI did not differ between the DCC and ECC groups (aOR 1.17 [95%CI 0.76-1.80]). At two years corrected age, DCC was associated with a 4.5-fold times increased adjusted odds of eGFR <90 mL/min/1.73m2. No significant associations were noted between DCC and albuminuria or elevated BP. Conclusions: DCC was not associated with decreased neonatal AKI, but was associated with higher adjusted odds of eGFR <90 mL/min/1.73m2 at two years.

SARS-CoV-2 Associated Respiratory Failure in a Preterm Infant and the Outcome after Remdesivir Treatment.

Severe coronavirus disease 2019 (COVID-19) occurs in approximately 10% of neonates infected with severe acute respiratory syndrome coronavirus 2. Guidelines for optimal management of severe COVID-19 in neonates do not exist. In this report, we describe a late-preterm neonate with severe COVID-19, requiring invasive mechanical ventilation who recovered following treatment with remdesivir and high dose dexamethasone.

PURA syndrome: neuromuscular junction manifestations with potential therapeutic implications.

PURA syndrome is caused by heterozygous de novo pathogenic variants in PURA. It is characterized by moderate to severe neurodevelopmental disability with a wide clinical spectrum and an evolving phenotype. We present two individuals with genetically confirmed PURA syndrome who had severe neonatal signs and symptoms and a novel phenotype suggestive of neuromuscular junction pathology. We demonstrate that PURA syndrome shares features consistent with a congenital myasthenic syndrome; we thus recommend electrodiagnostic study in neonates and infants with PURA syndrome, and consideration of salbutamol as a therapeutic option.
