Abstract
Background: The pathogen distribution and antibiotic susceptibility of the pathogens in early-onset sepsis (EOS) differ between countries. The epidemiological data from a limited number of studies about EOS in Turkey are insufficient. In this study, we aimed to evaluate the culture-proven EOS cases, causative microorganisms, antibiotic susceptibility patterns, and risk factors for mortality in EOS. Methods: This is a retrospective, single-center study over a 7-year period, from 2013 to 2020, at Zeynep Kamil Maternity and Children’s Hospital, İstanbul, Turkey. Results: During the study period, 8229 newborns were admitted to our neonatal intensive care unit. Culture-proven EOS was detected in 101 patients (0.12%). Out of these, 56 (55.4%) were Gram-positive, and 45 (44.5%) were Gram-negative sepsis. The most common isolated organism was E. coli (28.7%, n = 29), followed by GBS (16.8%, n = 17) and S. aureus (15.8%, n = 16). An ampicillin and gentamicin combination had antimicrobial coverage in 92.6% of cases. Seventeen patients (16.8%) died because of EOS. Severe neutropenia was found to be an independent risk factor for mortality in EOS (p = 0.001, OR = 14.4, CI 95%: 2.8–74). Conclusions: Although the majority of causative agents were Gram-positive (55.4%), the most common isolated organism was E. coli. An empirical antibiotic regimen of ampicillin and gentamicin continues to have an adequate coverage for EOS in our population.
