Comparing necrotizing enterocolitis risk among extremely preterm infants by use of human-milk or bovine-milk-based fortifier
摘要
To determine the incidence of necrotizing enterocolitis (NEC) among extremely premature infants (EPI: gestational age <28 weeks) fed a base exclusive human milk diet (EHMD) as a function of human-milk fortifier (human milk-based: HM-HMF or bovine milk-based: BM-HMF).
Study designRetrospective cohort of 703 EPI, 355 at Wolfson Children’s Hospital fed an EHMD with BM-HMF and 348 at UF Health Hospital fed an EHMD with HM-HMF fortification under similar feeding protocols. The outcomes of interest were NEC ≥ stage II, surgical NEC, and mortality.
ResultsBaseline characteristics were similar between the groups. NEC occurred in 9.5% of HM-HMF and 6.5% of BM-HMF fortified EPI [adjusted OR: 1.48 (0.83–2.63); p = 0.18]. Similarly, no differences were found in rates of surgical NEC or mortality or age at NEC onset.
ConclusionIn this large retrospective study in EPI, we did not detect any signal that fortification with HM-HMF reduced NEC incidence compared with BM-HMF supplementation.
