Gastroesophageal Reflux in Infants
Conditions
Brief summary
Gastroesophageal reflux (GER), defined as the backflow of gastric material into the esophagus, it is a condition with a high prevalence during the first year of life. The disease from Gastroesophageal reflux (GERD), a rarer condition, is defined as the presence of symptoms and complications caused by gastroesophageal reflux. For the diagnosis of GERD in infants it is necessary to perform instrumental diagnostic tests invasive. Several efforts have already been made to identify diagnostic strategies non-invasive but, at the state of the art, no non-invasive biomarker has yet been found of GERD in infants. Therefore, the aim of this pilot study is to identify possible biomarkers salivary gastroesophageal reflux in a population of infants with GER or GERD. Infants from 2 months to the first year of life, with age, will be prospectively enrolled postmenstrual \> 40 weeks, hospitalized, with symptoms of GER or GERD and undergoing 24-hour esophageal MII-pH. Saliva samples will be collected during the execution of the MII-pH of the esophagus 24 hours, at defined time points, at least 2 hours after the last meal, so as to study the circadian variations of their composition. A control group made up of healthy infants will also be enrolled and will be sampled a single saliva sample during a health assessment. The salivary pH, the buffer capacity, the electrolytes (Na, K, Cl, HCO3) and the saliva pepsin/pepsinogen concentrations of enrolled infants. The expected results include the description of the salivary biochemical profile of GER infants vs. GERD, so that the investigators can develop non-invasive diagnostic strategies and detect personalized therapeutic treatments.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| GERD SYMPTOMS | 2 years | dentify the prevalence of GERD in a cohort of infants with symptoms of gastroesophageal reflux |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| BIOCHEMICAL PROFILE | 2 years | Identify any differences in the biochemical profile (pepsin and pepsinogen concentration, electrolyte concentration, such as sodium and HCO3-) of saliva samples collected from healthy, GER and GERD patients. Investigate possible circadian variations in the biochemical profile (see above) of saliva samples collected at different time points during MII-pH performed in GER and GERD infants Correlate the onset of symptoms and nutrition to any changes in the biochemical profile (see above) of saliva samples taken from GER and GERD infants. |
