Letter to the Editor Comment on: Arnold Schwarzenegger or Danny DeVito? The fate of twins with necrotizing enterocolitis in the NICU

We read with great interest the article by Hellmann et al. titled "Arnold Schwarzenegger or Danny DeVito? The fate of twins with necrotizing enterocolitis in the NICU" [1]. In this comprehensive study, which is a major source in the literature, data from infants admitted to neonatal intensive care units between 2017 and 2023 were collected, and multiple pregnancies were identified in 8158 (3.2%) of 253,574 neonatal intensive care unit (NICU) infants. Although the probability of developing necrotizing enterocolitis (NEC) was found to be lower in multiple pregnancies compared to single births, if NEC develops in one infant in a set, the probability of the second sibling developing NEC was found to be higher than in the general NICU population (16.4% vs 2.6%, p < 0.01) [1].
