Abstract
Background and objective: Regurgitation symptoms in many GERD infants might affect their nutrition status. This review compares thickeners and hydrolysis formula with cow’s milk in the evolution of regurgitation, weight and stool consistency changes in infants with GERD based on currently available evidence, as the benefits of using AR-F in infants with GERD is still contradictory. There is also evidence that hydrolysed formula plays a crucial role in regulating reflux. Methods: The search terms ‘thickener formula/pre-thickener’ OR ‘cow’s milk allergy/hydrolysis formula’ AND ‘gastro-oesophageal reflux disease (GERD)/regurgitations’ were used to search the electronic databases of NUsearch, Google Scholar, ScienceDirect and PubMed for randomised controlled trials (RCTs) published between 2005 and 2020 for thickened formula and 2010-2020 for hydrolysed formula that involved infants (Results: Seven eligible RCTs met the inclusion criteria. Thickened whey protein formula significantly reduced daily regurgitations by up to 7.7 episodes, while the results were insignificant in thickened or normal extensive hydrolysed casein milk (-4.2 vs -3, respectively). However, rice thickener significantly reduced regurgitation and weight gain by 1.261 kg in two months. An insignificant difference in stool consistency was found in most trials (P >0.05), except for the thickened casein formula as 64% of participants had normal stool density (P= 0.45). Conclusion: This study identified that using either thickening formula or extensively hydrolysed formula significantly reduced the number of regurgitations per day (mean range: -1.2 to -7.1; P<0.05). It does, however, seem that hydrolysed whey formula thickened with hydrolysed rice can support weight gain in failure to thrive infants.
