RA06.07: PSYLLIUM SUPPLEMENTATION EFFECT ON ESOPHAGEAL FUNCTION TESTING AND SYMPTOMS IN PATIENTS WITH NON-EROSIVE GERD

Background Epidemiological data showed negative correlation between heartburn frequency and amount of dietary fiber consumed. However no interventional study was performed to prove clinically beneficial effect of dietary fibers in gastroesophageal reflux disease (GERD) patients. The aim of the study was to investigate the effect of dietary fiber on symptoms and esophageal function testing parameters in non-erosive GERD patients (NCT01882088) Methods Thirty six NERD patients were examined using food frequency questionnaire and in case of less than 20 g/day dietary fibre intake underwent high-resolution esophageal manometry and 24-hours esophageal pH-impedance. Language-specific GERD-Q questionnaire was used to assess symptoms. Repeated examinations were performed after 10 days of usual diet supplemented by psyllium 15.0 gram a day. Complete data of 30 NERD patients were available for the final analysis. Study design is shown in a figure 1. Wilcoxon matched pairs test was used to assess changes in the studied parameters Results The decrease in proportion of patients experiencing heartburn as well as GERD-Q score decrease were found. Minimal resting lower esophageal sphincter pressure increased from 5.41 ± 10.1 to 11.3 ± 9.4, P = 0.023. No change in residual LES pressure and mean resting pressure was found. Total number of gastroesophageal refluxes decreased from 67.9 ± 17.7 to 42.4 ± 13.5, P < 0.001 (Table 1). Conclusion Supplementation of diet with psyllium 5.0 gram TID in NERD patients led to significant increase of minimal esophageal resting pressure, decrease of number of gastroesophageal refluxes and frequency of heartburn per week.
