Outcome measures
Primary outcome
Components of 24-h Oesophageal pH Monitoring using a Digitrapper pH-Z ambulatory 24-hour pH and impedance recorder:
• Percent total time pH < 4
• Percent Upright time pH < 4
• Percent Supine time pH < 4
• Number of reflux episodes
• Number of reflux episodes ≥ 5 min
• Longest reflux episode (minutes)
• SI (symptom index for reflux)
• SSI (symptom sensitivity index)
• SAP (symptom associated probability)
Secondary outcome
The nuimber of visible refluxes and stool consistency as monitored by the parent using a 3-days diary.
Background summary
Uncomplicated gastro-esophageal reflux (GER) is a common problem affecting about 50% of all babies. Recovery may take more than two years, but the majority will do so within the first year of life. Because of the loss of nutrients due to reflux, GER may result in weight loss. Furthermore, the acidic refluxes may irritate the (lower part of) the esophagus. This means that any early reduction in the number of refluxes, including low-esophageal refluxes, is beneficial for the infant. Thickening the infant formulae with carob bean gum has shown to be succesful. Some evidence is available that carob bean gum is also effective at lower dose with regard to the number of visible refluxes. A lower dose also means a reduced impact on stool consistency. However, no information is available on the number of low-esopageal (invisible) refluxes. For that reason this study has been designed. In term born infants with an questionnaire indicated reflux (I-GERQ>7), two different concentrations (0.45 and 0.33 g/100ml infant formulae) of galactomannans (active part of carob bean gum) will be tested.
Study objective
A lower amount of cold soluble galactomannans (0.33g per 100ml) is as effective as 0.45g/100ml of hot soluble galactomannans in reducing the number of visible and invisible refluxes.
Study design
At study entry (day 0), recruited infants will be provided with a standard infant formula . After 7±2 days a baseline 18-24 hours pH monitoring will be performed. Following the baseline pH monitoring, infants will be fed in prone-reversed position with the allocated study formula. After 21±2 days (14 days of intervention), the 2nd and final pH-monitoring will take place. Just before baseline pH monitoring and at the end of the intervention period just before the final pH monitoring parents will fill in a 3-days questionnaire on episodes of visible regurgitation, crying, stool characteristics (consistency, colour, and frequency of defecation).
At entry of the study, at baseline measurement and at the end of the study the researcher will measure weight, height and head circumference of the infants.
Intervention
The included infants will be, based on study entry number, at random allocated to one of three study infant formulae. These products have the same basic composition, but differ in amount and type (hot or cold soluble) of galactomannans, whereas products with cold soluble galactomannans also contain small amounts of hydrolysed protein. The intervention will last for 14 days.
