Analysis of Bifidobacterium animalis subsp. lactis BB-12 ® and Lactobacillus rhamnosus GG on underweight and malabsorption in premature infants

Abstract

SUMMARY OBJECTIVE: This study aimed to explore and analyze the therapeutic effect of the combination of Bifidobacterium animalis subsp. lactis BB-12® and Lactobacillus rhamnosus GG on underweight and malabsorption in premature infants. METHODS: This is a retrospective study. The clinical data of 68 premature infants admitted to Beijing United Family Hospital (Private Secondary Comprehensive Hospital, Chaoyang District, Beijing, China) from January 2016 to January 2022 were analyzed retrospectively. Preterm infants less than 37 weeks of gestational age admitted to the neonatal intensive care unit were included in the study. Patients with intestinal malformations, necrotizing enterocolitis, etc., who require long-term fasting were excluded. A telephone follow-up was performed 3-6 months after discharge. They were classified as treatment groups A and B according to the treatment plan. The treatment group A included parenteral nutrition, enteral nutrition, etc. In treatment group B, based on treatment group A, the premature infants were treated with Bifidobacterium animalis subsp. lactis BB-12® and Lactobacillus rhamnosus GG. The time to regain birthweight and the weight on day 30 were compared between the two groups, as was the duration of transition from parenteral nutrition to total enteral nutrition. RESULTS: The time of weight regain birthweight in group B was shorter than that in group A (t=-2.560; t=-4.287; p<0.05). The increase of weight on day 30 in group B was significantly higher than that in group A (t=2.591; t=2.651; p<0.05). The time from parenteral nutrition to total enteral nutrition in group B was shorter than that in group A (z=-2.145; z=-2.236; p<0.05). CONCLUSION: In the treatment of premature infants, the combination of Bifidobacterium animalis subsp. lactis BB-12® and Lactobacillus rhamnosus GG can have a better therapeutic effect on the underweight and malabsorption of premature infants, and this treatment method can be popularized in clinics.
