Very low- quality evidence indicates that short-term use of an EHF compared with a CMF may prevent infant CMA .

BACKGROUND Infant formulas containing hydrolysed proteins have been widely advocated for preventing allergic disease in infants , in place of st and ard cow 's milk formula ( CMF ) .
However , it is unclear whether the clinical trial evidence supports this .
OBJECTIVES To compare effects on allergic disease when infants are fed a hydrolysed formula versus CMF or human breast milk .
If hydrolysed formulas are effective , to determine what type of hydrolysed formula is most effective , including extensively or partially hydrolysed formula ( EHF/PHF ) .
To determine whether infants at low or high risk of allergic disease , and whether infants receiving early short-term ( first few days after birth ) or prolonged formula feeding benefit from hydrolysed formulas .
Extensively hydrolyzed protein formula reduces acid gastro-esophageal reflux in symptomatic preterm infants.
BACKGROUND Gastro-esophageal reflux ( GER ) is diagnosed frequently in preterm infants . Pharmacological treatment of GER has some potential side effects . Conservative treatment of GER should be the first-line approach and should include body positioning and diet modifications . Formula-fed preterm infants experience frequently symptoms of feeding intolerance . Hydrolyzed protein formula ( HPF ) is often used in these infants due to their effects on gastrointestinal motility . AIMS To investigate the role of an extensively HPF ( eHPF ) on GER indexes in formula-fed preterm infants with symptoms of both GER and feeding intolerance . STUDY DESIGN R and omized crossover trial . SUBJECTS Preterm infants ( gestational age ≤33 weeks ) with symptoms of feeding intolerance ( large gastric residuals , abdominal distension and constipation ) and GER ( frequent regurgitations and /or postpr and ial desaturations ) . OUTCOME MEASURES GER indexes detected by 24-h combined multichannel intraluminal impedance and pH monitoring . GER indexes detected after 4 feeds of an eHPF were compared to those detected after 4 feeds of a st and ard preterm formula ( SPF ) by Wilcoxon signed ranks test . A p<0.05 was considered statistically significant . RESULTS eHPF significantly reduced the number of GERs detected by pH monitoring ( p=0.036 ) and also the reflux index ( p=0.044 ) compared to SPF . No differences in impedance bolus exposure indexes nor in GER height were detected . CONCLUSIONS The use of an eHPF should be evaluated for reducing esophageal acid exposure in preterm infants with feeding intolerance and symptoms of GER . Future research should focus on the evaluation of an eHPF adequate for preterm infants in improving clinical symptoms of GER
