Li, Q., An, Y., Liu, L. et al. Differences in the Clinical Characteristics of Early- and Late-Onset Necrotizing Enterocolitis in Full-Term Infants: A Retrospective Case-Control Study. Sci Rep 7, 43042 (2017). https://doi.org/10.1038/srep43042
Information regarding the influence of age at onset on prognosis in full-term infants with necrotizing enterocolitis (NEC) is limited, and identifying differences between the clinical characteristics of early-onset NEC (EO-NEC) and late-onset NEC (LO-NEC) may be helpful in the determination of effective management strategies. In the present study, the medical records of 253 full-term infants with NEC were reviewed, and the clinical characteristics of the EO-NEC group (n = 150) and the LO-NEC group (n = 103) were compared. Infants in the EO-NEC group were characterized by increased gestational age and higher rates of stage III NEC and peritonitis when compared with LO-NEC infants (P < 0.05). Mortality was significantly associated with stage III NEC, peritonitis, sepsis, respiratory failure and shock in univariate analysis (P < 0.05). In logistic regression analysis, peritonitis and renal failure were identified as independent risk factors for mortality in infants with EO-NEC, and peritonitis and respiratory failure were significant predictors of mortality in neonates with LO-NEC. Our finding indicated that the characteristics of the severe medical conditions identified in infants with EO-NEC were distinct from those observed in infants with LO-NEC. Peritonitis and kidney failure and peritonitis and respiratory failure were identified as risk factors for mortality in EO-NEC and LO-NEC infants, respectively.
