[Efficacy of trimebutine in the treatment of functional gastrointestinal disorders: an observational multicenter study]

Role of Inflammation and Motility Disorders in the Development, Course and Consequences of Functional Gastrointestinal and Biliary Tract Diseases (Literature Review and Expert Panel Resolution)

   Aim: to present the results of the Expert Panel with a discussion of modern concepts of the pathogenesis of functional gastrointestinal diseases and the possibilities of multitarget therapy with trimebutine.

   Key points. Low-grade inflammation can be considered as a morphological substrate of functional diseases with an increase in activated mastocytes and eosinophils, T-helpers 2 and T-helpers 17 in the gastrointestinal mucosa. In the development in the content of visceral hypersensitivity, the functional connection between mastocytes and TRPV1-positive sensory endings of the vagus nerve is of great importance. Proinflammatory cytokines and matrix metalloproteinases can enter the systemic circulation, provoking the development of systemic manifestations. Increased levels of proinflammatory cytokines are supported by altered intestinal permeability and microbiota. Functional diseases are believed to modify the symptoms and course of concomitant organic diseases of the gastrointestinal tract (for example, functional diseases of the biliary tract may contribute to the development of cholelithiasis, pancreatitis). The peripheral μ-, κ- and δ-receptor agonist trimebutine (Trimedat®) regulates the production of enterohormones, modulates motility throughout the gastrointestinal tract and normalizes visceral sensitivity. The effectiveness of trimebutine in the treatment of functional disorders has been shown in various studies. Trimebutine helps reduce the production of proinflammatory cytokines, including interleukin-6.

   Conclusion. In the treatment of functional diseases of the gastrointestinal tract, trimebutine can be considered as a multitarget agent, since the drug helps to normalize motility, reduces the degree of visceral hypersensitivity, exhibits anti-inflammatory and neuroregenerative effects, and can also increase the effectiveness of treatment of concomitant diseases.

Efficacy and Mechanism of Trimebutine Maleate Combined with Lactulose in the Treatment of Constipation-Predominant Irritable Bowel Syndrome in the Elderly

Objective

Study on the efficacy and mechanism of trimebutine maleate combined with lactulose in the treatment of constipation-predominant irritable bowel syndrome (IBS-C) in the elderly.

Methods

From March 2019 to March 2021, 102 elderly patients with IBS-C were randomly divided into the observation group (51 cases) and the control group (51 cases). The observation group was treated with trimebutine maleate combined with lactulose, while the control group was treated with lactulose. Comparison of the clinical effects of the two groups. Comparison of vasoactive intestinal peptide (VIP) levels, neuropeptide Y (NPY) levels, and quality of life scores before and after treatment between the two groups. Documentation of adverse reactions during treatment.

Results

The improvement of clinical symptoms in the observation group was significantly better than that in the control group, and the difference is statistically significant (P < 0.05). The level of VIP after treatment in the observation group was significantly lower than that in the control group and before treatment, and the differences were statistically significant (P < 0.05). The level of NPY after treatment in the observation group was significantly higher than that in the control group and before treatment, and the differences were statistically significant (P < 0.05). The scores of dietary restrictions and health worries in the control group after treatment were significantly higher than those before treatment, and the differences were statistically significant (P < 0.05). The scores of anxious, behavioral conflict, dietary restrictions, health worries, social response, and family relationship in the observation group after treatment were significantly higher than those in the control group and before treatment, and the differences were statistically significant (P < 0.05). There were no serious adverse effects in either group during the treatment period, with some patients experiencing dizziness and dry mouth, which improved after discontinuation of the drug, without special intervention.

Conclusion

Trimebutine maleate combined with lactulose can improve clinical symptoms and quality of life in elderly patients with IBS-C, and its mechanism of action may be related to the regulation of the body's VIP and NPY levels.

Clinical Recommendations of Russian Gastroenterological Association and RENDO Endoscopic Society on Diagnosis and Treatment of Gastritis and Duodenitis

Aim.The clinical guidelines are intended to supplement specialty decision-making for improved aid quality in patients with gastritis and duodenitis though acknowledging the latest clinical evidence and principles of evidencebased medicine.Key points.Gastritis is an inflammatory disease of stomach mucosa, with a separate definition of acute and chronic gastritis. Chronic gastritis is a cohort of chronic diseases uniting a typical morphology of persistent inflammatory infiltration, impaired cellular renewal with emergent intestinal metaplasia, atrophy and epithelial dysplasia of gastric mucosa. Oesophagogastroduodenoscopy (OGDS) or high-resolution OGDS with magnified or non-magnified virtual chromoendoscopy, including targeted biopsy for atrophy and intestinal metaplasia grading and neoplasia detection, are recommended to verify gastritis and duodenitis, precancer states and/or gastric mucosal changes. All chronic gastritis patients positive for H. рylori should undergo eradication therapy as aetiological and subsidiary for gastric cancer prevention. Chronic gastritis patients with symptoms of dyspepsia (epigastric pain, burning and congestion, early satiety), also combined with functional dyspepsia, are recommended proton pump inhibitors, prokinetics, rebamipide and bismuth tripotassium dicitrate in symptomatic treatment. With focal restricted intestinal metaplasia, follow-up is not required in most cases, mainly when advanced atrophic gastritis is ruled out in high-quality endoscopy with biopsy. However, a familial history of gastric cancer, incomplete intestinal metaplasia and persistent H. pylori infection render endoscopy monitoring with chromoendoscopy and targeted biopsy desirable once in three years. Patients with advanced atrophic gastritis should have high-quality endoscopy every 3 years, and once in 1–2 years if complicated with a familial history of gastric cancer.Conclusion.The recommendations condense current knowledge on the aetiology and pathogenesis of gastritis and duodenitis, as well as laboratory and instrumental diagnostic techniques, main approaches to aetiological H. pylori eradication and treatment of dyspeptic states.
