Multidrug resistant Gram-negative infections in neonatology
Sociedad Argentina de Pediatría..
INTRODUCTION: Multidrug resistant Gramnegative (MDRGN) infections are an increasing problem in neonatal intensive care units. The objective of this study was to establish the epidemiological, clinical, microbiological, and evolutionary characteristics of carbapenem-resistant MDRGN infections and the risk factors for them at the Division of Neonatology of a tertiary care hospital.
POPULATION AND METHOD: A retrospective cohort study was done in this Division in patients with a documented MDRGN infection between 4/24/2013 and 4/29/2015.
RESULTS: Twenty-one patients were included. Their median gestational age and birth weight were 35 weeks and 2070 g, respectively. Eighteen patients (86 %) had a positive blood culture; the most commonly isolated microorganism was Acinetobacter baumannii (17 patients, 81 %), followed by carbapenemase-producing Klebsiella pneumoniae (3 patients, 14 %) and Enterobacter cloacae (1 patient, 5 %).The median age at diagnosis was 28 days and all patients had risk factors for infection, including surgery, assisted mechanical ventilation, parenteral nutrition, central venous line, and antibiotics. The definite antibiotic therapy included colistin in all cases; in combination, in 84 %. Five patients (24 %) died due to the infection. Prematurity and a birth weight < 2000 g were statistically significant risk factors associated with mortality (p = 0.03 and 0.01, respectively).
CONCLUSION: MDRGN infections were observed in patients with predisposing factors. Acinetobacter baumannii was the main etiologic agent. Mortality was high and related to prematurity and a low birth weight.
