The prokinetic cisapride, an important therapeutic option in functional gastrointestinal (GI) disorders, was withdrawn from the market 15 years ago due to rare severe side effects. Likewise in 2014, the use of metoclopramide (MCP) and domperidone in functional GI disorders (FGID) was restricted, consequently leaving a therapeutic gap in clinical practice. A systematic review revealed that the herbal medicinal product (HMP) STW 5 presents a therapeutic option equivalent to MCP and cisapride. STW 5 is the only HMP for which efficacy has been shown in randomized controlled clinical trials (RCTs) in functional dyspepsia and irritable bowel syndrome, based on its multitarget effect on numerous etiological factors...

The regulation of gastrointestinal motility encompasses several overlapping mechanisms including highly regulated and coordinated neurohormonal circuits. Various feedback mechanisms or 'brakes' have been proposed. While duodenal, jejunal, and ileal brakes are well described, a putative distal colonic brake is less well defined. Despite the high prevalence of colonic motility disorders, there is little knowledge of colonic motility owing to difficulties with organ access and technical difficulties in recording detailed motor patterns along its entire length...

Irritable bowel syndrome (IBS) is a functional bowel disease with a complicated etiopathogenesis, often characterized by gastrointestinal motility disorder and high visceral sensitivity. IBS is a comprehensive multi-systemic disorder, with the interaction of multiple factors, such as mental stress, intestinal function and flora, heredity, resulting in the disease. The existence of a common mechanism underlying the aforementioned factors is currently unknown. The lack of therapies that comprehensively address the disease symptoms, including abdominal pain and diarrhea, is a limitation of current IBS management...

BACKGROUND: Motility and the coordination of moving food through the gastrointestinal tract rely on a complex network of neurons known as the enteric nervous system (ENS). Despite its critical function, many of the molecular mechanisms that direct the development of the ENS and the elaboration of neural network connections remain unknown. The goal of this study was to transcriptionally identify molecular pathways and candidate genes that drive specification, differentiation and the neural circuitry of specific neural progenitors, the phox2b expressing ENS cell lineage, during normal enteric nervous system development...

Ghrelin was discovered in 1999 as the endogenous ligand of the growth-hormone secretagogue receptor 1a (GHSR1a). Since then, ghrelin has been found to exert a plethora of physiological effects that go far beyond its initial characterization as a growth hormone (GH) secretagogue. Among the numerous well-established effects of ghrelin are the stimulation of appetite and lipid accumulation, the modulation of immunity and inflammation, the stimulation of gastric motility, the improvement of cardiac performance, the modulation of stress, anxiety, taste sensation and reward-seeking behavior, as well as the regulation of glucose metabolism and thermogenesis...

Gastroesophageal reflux disease (GERD) is a common condition that has a substantial impact on quality of life in patients and is a leading risk factor for esophageal adenocarcinoma. Now therapy with proton pump inhibitors (PPIs) is a basic method in the treatment of patients with GERD; however, one third of the patients do not respond to the therapy used. The causes of refractory GERD are a fairly large group of heterogeneous factors contributing to the inefficacy of PPIs in adequate dosage. Among these factors, there is low compliance by patients to the prescribed treatment regimen; nocturnal acid breakthrough; СУР2С19 gene polymorphism; chiasm syndrome with functional diseases of the gastrointestinal tract; non-acidic refluxes in a patient; thoracic esophageal motility disorders; the increased number and duration of transient lower esophageal sphincter relaxation periods; hiatus hernia; and misdiagnosis...

Curry-Jones syndrome (CJS) is a pattern of malformation that includes craniosynostosis, pre-axial polysyndactyly, agenesis of the corpus callosum, cutaneous and gastrointestinal abnormalities. A recurrent, mosaic mutation of SMO (c.1234 C>T; p.Leu412Phe) causes CJS. This report describes the gastrointestinal and surgical findings in a baby with CJS who presented with abdominal obstruction and reviews the spectrum of gastrointestinal malformations in this rare disorder. A 41-week, 4,165 g, female presented with craniosynostosis, pre-axial polysyndactyly, and cutaneous findings consistent with a clinical diagnosis of CJS...

BACKGROUND/AIMS: Ineffective esophageal motility (IEM) is the most common gastrointestinal motility disorder. Studies have reported that IEM is related to gastroesophageal reflux disease (GERD). However, the relationship between IEM and GERD remains uncertain. This study aims to clarify this relationship retrospectively. METHODS: We analyzed 195 subjects who underwent high-resolution manometry between January 2011 and September 2016. Of these subjects, 72 had normal esophageal motility (NEM) and 26 had IEM...

BACKGROUND: Gastrointestinal (GI) motility disorders represent a group of problems that more constantly encountered in preterm infants. However, whether hypoxia exposure contributes to the GI dysfunctions is still unclear. METHODS: Newborn mice were exposed to hypoxia (10%) from P1 to P7. Intestinal motilities were examined by a strain gauge transducer. The proliferation of ICCs was detected by using immunostaining for BrdU, Ki67, Kit, Ano1, and insulin-like growth factor 1 receptor (IGF-1R+)...

The intestinal tract of the newborn is particularly sensitive to gastrointestinal disorders, such as infantile diarrhea or necrotizing colitis. Perinatal development of the gut also encompasses the maturation of the enteric nervous system (ENS), a main regulator of intestinal motility and barrier functions. It was recently shown that ENS maturation can be enhanced by nutritional factors to improve intestinal maturation. Bioactivity of milk proteins is often latent, requiring the release of bioactive peptides from inactive native proteins...

There is an unmet need for effective pharmacological therapies for constipation, a symptom that significantly deteriorates patients' quality of life and impacts health care. Ghrelin is an endogenous ligand for the growth hormone secretagogue receptor and has been shown to exert prokinetic effects on gastrointestinal (GI) motility via the vagus and pelvic nerves. The pharmacological potential of ghrelin is hampered by its short half-life. Ghrelin receptor (GRLN-R) agonists with enhanced pharmacokinetics were thus developed...

Autoimmune autonomic ganglionopathy (AAG) is an immune-mediated disorder that leads to various autonomic failures associated with anti-ganglionic acetylcholine receptor antibodies (anti-gAChR-Abs). Diffuse esophageal spasm (DES) is an uncommon esophageal motility disorder. We herein report the case of a 68-year-old woman with DES as a partial symptom of AAG. She presented with chronic esophageal transit failure, constipation, and numbness of the hands and feet, Adie's pupil, thermal hypoalgesia, and decreased deep tendon reflexes...

Nutrient-sensing receptors, including fatty acid receptors (FFA1-FFA4), Ca(2+)-sensing receptors and Zn(2+)-sensing receptors, are involved in several biological processes. These receptors are abundantly expressed in the GI tract, where they have been shown to play crucial roles in regulating GI function. This review provides an overview of the GI functions of fatty acid and mineral receptors, including the regulation of gastric and enteroendocrine functions, GI motility, ion transport and cell growth. Recently, several lines of evidence have implicated these receptors as promising therapeutic targets for the treatment of GI disorders, for example, inflammatory bowel disease, colorectal cancer, metabolic syndrome and diarrheal diseases...

BACKGROUND: The joint hypermobility syndrome (JHS) is a common non-inflammatory connective tissue disorder which frequently co-exists with postural tachycardia syndrome (PoTS), a form of orthostatic intolerance. Gastrointestinal symptoms and dysmotility have been reported in PoTS. Dysphagia and reflux are common symptoms in JHS, yet no studies have examined the physiological mechanism for these, subdivided by PoTS status. METHODS: Thirty patients (28 female, ages: 18-62) with JHS and symptoms of reflux (n=28) ± dysphagia (n=25), underwent high-resolution manometry and 24 hour pH-impedance monitoring after questionnaire-based symptom assessment...
