Effects on gastroesophageal reflux of donkey milk-derived human milk fortifier versus standard fortifier in preterm newborns. Additional data from Fortilat study.

Background : Feeding intolerance, defined as the inability to digest enteral feeding, is a frequent diagnosis in very preterm infants. It is characterized by abdominal distension, delayed gastric emptying and increased frequency and severity of gastroesophageal reflux (GER). As seen in the FortiLat trial, human milk fortification with the new donkey milk-derived human milk fortifier (DF) seems to improve feeding tolerance in these infants. The aim of this ancillary study of the FortiLat trial was to evaluate the effects of using the DF compared with bovine milk-derived fortifier (BF) on GER in VLBW infants.Methods : Over a total of 156 preterm infants enrolled into the FortiLat trial (gestational age <32 weeks and/or birth weight <1500 g) and randomized into BF-arm or DF-arm we selected all infants with clinical signs of GER and cardiorespiratory (CR) symptoms at day 21 of fortification. All the infants underwent CR and multichannel intraluminal impedance and pH (MII/pH) monitoring associated with gastric ultrasound to evaluate GER characteristics, GER-CR temporal associations and gastric emptying time.Results : 10 infants were enrolled, 5 in the DF-arm. At MII/pH infants enrolled into the DF-arm showed a lower GER frequency than BF-arm infants: 2.02(1.95-3.26) vs 4.82(2.84-5.94) GER/hour (p=0.036). No infant had a significant symptom association probability index between GER and CR events. Half gastric emptying time was similar in DF and BF-arm infants: 45.03(42.74-47.02) vs. 48.57(44.73-48.77) min. (p=0.744)Conclusions : The use of donkey derived human milk fortifier reduced the GER frequency and consequently should be recommended in infants with feeding intolerance.Trial Registration : ISRCTN -ISRCTN70022881.
