title: Efficacy and safety of intravenous colistin in preterm infants with nosocomial sepsis caused by Acinetobacter baumannii.
abstract: OBJECTIVE
  To describe the efficacy of intravenous colistin on clinical and microbiological outcomes in preterm infants with nosocomial sepsis in neonatal intensive care unit (NICU) and define adverse events observed with this treatment.
  
  
  METHODS
  The records of preterm infants who received colistin with or without positive cultures in the NICU were retrospectively reviewed. Patients were evaluated for response to therapy and side effects.
  
  
  RESULTS
  A total of 21 preterm infants with medians of 28 weeks (23-36) gestational age and 870 g (620-2,650) birth weight were included. The median duration and dose of colistin therapy were 9 days (3-26) and 3 mg/kg/d (2-5). Recovery rate in patients including all with/without positive culture was 81% (17/21). Microbiological clearance by colistin was 69% (9/13). The major side effect observed was acute kidney injury (19%). At least 24% of infants required electrolyte supplementation during the colistin therapy. Magnesium levels were significantly lower at the end of the colistin therapy (p < 0.001). Acute kidney injury and electrolyte disturbances including hypomagnesemia were reversible in all surviving patients.
  
  
  CONCLUSIONS
  We suggest that renal function tests and serum electrolytes should be monitored closely and replaced in case of any need during the colistin therapy in preterm infants.
