Lacticaseibacillus rhamnosus and breastmilk are associated with a decreased risk of atopic dermatitis in very low birth weight premature infants Uberos Fernández, José García-Cuesta, A.

Probiotics Human breastmilk Newborn Very low birth weight Atopic eczema In this study, we analyse the influence of nutrition during the early neonatal period on the development and prevention of atopic dermatitis (AD) in children with a history of very low birth weight (VLBW). A retrospective cohort study was performed of VLBW preterm infants to assess the risk of their developing AD during childhood, according to nutrition with breastmilk and/or probiotic supplementation during the neonatal period. The analysis focused on nutritional and early childhood follow-up data for 437 newborns, of whom 184 received probiotics up to 36 weeks postmenstrual age. AD was present in 23.5% of the study sample. Of the children who did not develop AD, 44.9% had received probiotics from birth to 36 weeks of gestational age. Therefore, the administration of probiotics to infants at less than 36 weeks postmenstrual age is associated with a protective effect against the development of AD (odds ratio (OR) 0.57; 95% confidence interval (CI) 0.34-0.93). Moreover, a protective interaction was observed between probiotic administration and breastmilk (OR 0.46; 95% CI 0.25-0.82). The adjusted data in the regression model allow us to observe a statistically significant association with the protective effect of Lacticaseibacillus rhamnosus with the development of AD at school age (OR 0.55; 95% CI 0.30-0.99). Probiotic supplementation in VLBW newborns is associated with a decreased risk of subsequent development of AD. Breastmilk strengthens the protective effect of probiotics against the development of AD. 2024-05-22T11:18:05Z 2024-05-22T11:18:05Z 2023-11-20 journal article Uberos Fernández, José et al.
