Probiotics and growth in preterm infants: A randomized controlled trial, PREMAPRO study

Résumé

BACKGROUND & AIMS: Recent studies have suggested that the gut microflora has metabolic effects. We aimed to evaluate postnatal growth in preterm infants who received different probiotic supplements, and to assess the safety of probiotic administration. METHODS: This prospective, randomized, double-blind, controlled trial was performed at three tertiary care neonatal units. Preterm infants were randomly assigned to receive daily supplementation over 4-6 weeks with placebo (group C) or probiotics (group P). Group P comprised three subgroups: P1 received Bifidobacterium lactis, P2 received Bifidobacterium longum, and P3 received B. lactis and B. longum. We assessed postnatal growth during the supplementation period and up to a corrected gestational age (GA) of 41 weeks when body composition was assessed using whole-body dual-energy X-ray absorptiometry. Aerobic and anaerobic blood cultures were performed on suspicion of late-onset sepsis. RESULTS: The study comprised 199 preterm infants with a mean GA of 29.1 ± 1.4 weeks and a mean birth weight of 1173 ± 210 g, who received a placebo (group C, n = 52) or probiotics (group P, n = 147) from the first week of life. At the end of the supplementation period, no statistically significant differences were seen between the groups in relation to the mean body weight (group C = 1906 ± 23 g, group P = 1875 ± 14 g, p = 0.25), length, or head circumference. The incidence rates of necrotizing enterocolitis and late-onset sepsis were similar in the two groups. At the corrected GA of 41 weeks, there were no differences between the groups with respect to anthropometric measurements or body composition analysis. CONCLUSIONS: Preterm infants receiving Bifidobacterium supplements did not exhibit better postnatal growth compared with those who received placebo treatment. No adverse effects were associated with probiotic administration. Registered under ClinicalTrials.gov Identifier no. NCT01379417.
