Short-course antibiotic therapy for pneumonia in the neonatal intensive care unit.

Objective: To determine the adherence and safety outcomes of a 5-day antibiotic course with a "time-out" for treatment of "blood culture-negative" pneumonia in the NICU.

Study Design: Prospective surveillance of all infants diagnosed with pneumonia at 7 NICUs from 8/2020-12/2021. Safety outcomes were defined a priori by re-initiation of antibiotic therapy within 14 days after discontinuation and overall and sepsis-related mortality.

Short-course empiric antibiotic therapy for possible early-onset sepsis in the NICU.

Objective: On 2/2019, the Neonatal Antimicrobial Stewardship Program at Nationwide Children's Hospital recommended reducing empirical antibiotic therapy for early-onset sepsis (EOS) from 48 to 24 hours with a TIME-OUT. We describe our experience with this guideline and assess its safety.

Methods: Retrospective review of newborns evaluated for possible EOS at 6 NICUs from 12/2018-7/2019.

Thrombotic thrombocytopenic purpura in a newborn.

This report describes a newborn who presented with hyperbilirubinemia and thrombocytopenia. The patient recovered after treatment with antibiotics, phototherapy, and a platelet transfusion. Analysis of the plasma von Willebrand factor-cleaving metalloprotease, ADAMTS13, revealed low protease activity in the patient and her two siblings, and a mild deficiency in both parents.
