Abstract
AIM: To evaluate the effectiveness of enteroprotector Rebamipide in the treatment of enteropathy with impaired membrane digestion (EIMD).
MATERIALS AND METHODS: We examined 102 patients aged 18 to 50 years (41 men and 61 women) with clinical signs of irritable bowel syndrome (n=65), functional diarrhea (n=33), and functional constipation (n=4) according to Rome IV criteria (2016). The activities of glucoamylase (GA), maltase, sucrase and lactase were determined by Dahlquist-Trinder method in duodenal biopsies obtained during esophagogastroduodenoscopy. The control group consisted of 20 healthy people aged 23-47. They showed following average enzyme activity: lactase - 42±13 ng glucose on 1 mg of tissue per minute, GA - 509±176, maltase - 1735±446, sucrase - 136±35 ng glucose on 1 mg of tissue per minute. These numbers were taken as the norm.
RESULTS: The activity of the disaccharidases was reduced in 89.2% out of 102 patients, and they were diagnosed with EIMD. Thirteen patients with EIMD were recommended to maintain the FODMAP diet and take enteroprotector Rebamipide 100 mg 3 times a day for 12 weeks. After 3 months 11 patients reported decreased or no flatulence, abdominal pain, stool disorder; 2 patients reported no change. The activity of GA increased to an average of 149±82 (by 78%, p=0.016), maltase - to 864±472 (by 131%, p=0.0019), sucrase - 63±35 (by 95%, p=0.0041) and lactase - 10±8 ng glucose on 1 mg of tissue per minute. The activity of lactase did not change.
CONCLUSION: We discovered a previously unknown phenomenon of the disaccharidases activity increase in duodenal mucosa and improved carbohydrates tolerance in the patients with EIMD taking Rebamipide in the dose 300 mg/day for 12 weeks.
