Post-pancreatitis diabetes mellitus (PPDM) is a sub-type of diabetes of the exocrine pancreas that develops after acute or chronic inflammation of the pancreas. While pro-inflammatory mileu, glucose metabolism, and lipid metabolism in PPDM have been investigated, little is known about gastrointestinal function in post-pancreatitis setting. This article overviews studies on epidemiology and impact of gastroparesis in the setting of type 1 and type 2 diabetes, with a view to estimating the possible burden of gastrointestinal dysfunction in PPDM...

Functional gastrointestinal disorders (FGIDs), such as irritable bowel syndrome (IBS) and chronic constipation (CC), are commonly diagnosed conditions in clinical practice which create a substantial global burden. Since the farnesoid X receptor (FXR) and bile acids (BAs) are responsible for maintaining homeostasis in the GI tract, any disturbances in the expression of FXR or the composition of BAs may contribute to the development of the GI symptoms. Alterations in the mechanism of action of FXR directly affect the BAs pool and account for increased intestinal permeability and changes in abundance and diversity of gut microbiota leading to intestinal dysmotility...

Functional gastrointestinal (GI) diseases are common and there are patients who are refractory to medical therapies as not all treatments work in all patients. Consequently, a large number of patients with functional GI diseases use complementary and alternative medicine, such as acupuncture or electroacupuncture (EA). In this issue, Zheng et al. reported interesting results of a multi-center placebo-controlled clinical study on the use of EA for treating refractory functional dyspepsia; another study reported a multi-center clinical trial on EA for chronic functional constipation; Liang et al...

PURPOSE OF REVIEW: We reviewed the current state of total pancreatectomy with islet autotransplantation (TPIAT) for chronic pancreatitis and recurrent acute pancreatitis (RAP). RECENT FINDINGS: An increasing number of centers in the United States and internationally are performing TPIAT. In selected cases, TPIAT may be performed partially or entirely laparoscopically. Islet isolation is usually performed at the same center as the total pancreatectomy surgery, but new data suggest that diabetes outcomes may be nearly as good when a remote center is used for islet isolation...

Irritable bowel syndrome (IBS) in humans is described as the recurrent presence of gastrointestinal signs, without gross histopathologic evidence of inflammation and of other morphologic lesions; however, it is a syndrome not unanimously defined in veterinary medicine. There is some evidence that dysmotility could be related to stressors in some dogs that present with clinical signs (e.g. chronic idiopathic large-bowel diarrhea) that share overlapping aspects with human IBS. The authors hypothesize that an IBS-like condition, similar to that described in humans, might also be present in dogs...

Chronic intestinal pseudo-obstruction (CIPO) is a rare disorder characterized by an impairment of coordinated propulsive activity in the gastrointestinal (GI) tract, which clinically mimics mechanical intestinal obstruction. CIPO is the most severe and debilitating form of GI dysmotility. CIPO may be primary or be secondary to pathology at any level of the brain-gut axis as well as systemic disease. The clinical features of CIPO are pleomorphic and largely depend on the site and extent of the segment of the GI tract involved...

BACKGROUND AND PURPOSE: Postural orthostatic tachycardia syndrome (POTS) is increasingly recognized as a complication affecting recovery from concussion. Individuals with POTS demonstrate refractory dizziness, lightheadedness, cognitive dysfunction, fatigue, headache, chronic pain, nausea and gastrointestinal dysmotility, activity and exercise intolerance, syncope, and tachycardia. Subtypes of POTS may include hypovolemia, hyperadrenergic states, autonomic neuropathy, and underlying autoimmunity, which may variably impact response to rehabilitation in varying ways...

Although gastrointestinal complications are a common feature of patients with chronic kidney disease (CKD), the impact of uremia on bowel motility remains poorly understood. The present study was, therefore, designed to investigate the impact of uremia on gut motility. Kidney failure was induced in mice by chemical nephrectomy using an adenine diet (0.25% w/w ). Gastrointestinal transit time and colon motility were explored in vivo and ex vivo . Colons from control mice were incubated with uremic plasma or uremic toxins (urea, indoxyl-sulfate or p-cresyl-sulfate) at concentrations encountered in patients with end-stage renal disease...

BACKGROUND: The existence of several autoantibodies suggests an autoimmune basis for gastrointestinal (GI) dysmotility. Whether GI motility disorders are features of autoimmune autonomic ganglionopathy (AAG) or are related to circulating anti-ganglionic acetylcholine receptor (gAChR) antibodies (Abs) is not known. The aim of this study was to determine the associations between autonomic dysfunction, anti-gAChR Abs, and clinical features in patients with GI motility disorders including achalasia and chronic intestinal pseudo-obstruction (CIPO)...

OBJECTIVE: Chronic inflammation in HIV-infected individuals drives disease progression and the development of comorbidities, despite viral suppression with combined antiretroviral therapy. Here, we sought evidence that vagal dysfunction, which occurs commonly as part of HIV-associated autonomic neuropathy, could exacerbate inflammation through gastrointestinal dysmotility, small intestinal bacterial overgrowth (SIBO), and alterations in patterns of soluble immune mediators. DESIGN: This is a cross-sectional observational study...

BACKGROUND: Gastrointestinal dysmotility (GID) covers a spectrum of disorders disrupting enteric neuromuscular co-ordination which, when severe, causes intractable gastrointestinal symptoms and malnutrition and is a recognized cause of chronic intestinal failure. To date, no study has provided an in-depth account of the experiences of patients with severe GID and their psychosocial needs. This study aimed to explore patients' experiences from symptom onset and the process of seeking and receiving a diagnosis...

BACKGROUND: The mechanism underlying gastrointestinal (GI) dysmotility associated with chronic pancreatitis (CP) has not been fully elucidated, and enteric nervous system (ENS) has an important regulatory role in gastrointestinal motor function. The aim of this study is to investigate the effect of ENS in the colonic hypomotility induced by trinitrobenzene sulfonic acid (TNBS) infusion which mimics CP. METHODS: Male Sprague-Dawley rats were submitted to CP which was induced by pancreatic infusion of 2% TNBS, or sham group with treatment of equal saline...

OBJECTIVES: Patients with mitochondrial disorders (MD) frequently present with gastrointestinal complaints, mainly gastrointestinal dysmotility, that interfere with their food intake. A deterioration of their nutritional state may worsen the course of the disease. Our study aimed to evaluate a simple screening tool to identify nutritional risk and perform an extended nutritional assessment to explore the potential presence of deficiencies in this population compared with controls. METHODS: A prospective cohort study was conducted to compare outpatients with MD to matched healthy controls...

Exposure to continuous life stress often causes gastrointestinal (GI) symptoms. Studies have shown that neuropeptide Y (NPY) counteracts the biological actions of corticotrophin-releasing factor (CRF), and is involved in the termination of the stress response. However, in chronic repeated restraint stress (CRS) conditions, the actions of NPY on GI motility remain controversial. To evaluate the role of NPY in mediation of the adaptation mechanism and GI motility in CRS conditions, a CRS rat model was set up...

Purpose: Minimal change esophagitis (MCE) is a reflux disease without mucosal breaks, known to be partially associated with abnormal gastric motor function. Electrogastrography (EGG) is commonly applied to assess gastric motor function in a noninvasive fashion. We aimed to determine the relationship between MCE and gastric myoelectrical activity (GME) recorded on EGG in children. Methods: We retrospectively assessed the records of 157 children without underlying disease who underwent both EGG and upper gastrointestinal endoscopy at Gachon University Gil Medical Center between January 2010 and June 2015...

BACKGROUND: Gastrointestinal (GI) motility disorders are common in children. Treatment is challenging with limited medical and surgical options. Pyridostigmine, an acetyl cholinesterase inhibitor, increases acetylcholine at the neuromuscular junction promoting intestinal contractions. Little is known about the role and dosing of pyridostigmine in pediatric GI motility disorders. METHODS: We present a case series of children with GI dysmotility managed with oral pyridostigmine...

Chronic intestinal pseudo-obstruction (CIPO) is a severe form of gastrointestinal dysmotility (often due to derangement of the innervation/smooth muscle/interstitial cells of Cajal) with recurrent episodes of intestinal subocclusion mimicking a mechanical obstruction. Because of its complexity and heterogeneity, CIPO is often misdiagnosed or remains unrecognized until advanced stages. Management is a critical aspect in CIPO patient care. So far, most prokinetic drugs have not proven efficacy in restoring intestinal propulsion, thus nutritional support, fluid/electrolyte replacement, and antibiotics are the mainstay of treatment...

Chronic constipation and gastrointestinal motility disorders constitute a large part of a gastroenterology practice and have a significant impact on a patient's quality of life and lifestyle. In most cases, medications are prescribed to alleviate symptoms without there being an objective measurement of response. Commonly used investigations of gastrointestinal transit times are currently limited to radiopaque markers or electronic capsules. Repeated use of these techniques is limited because of the radiation exposure and the significant cost of the devices...

The use of opioid medications on both an acute and chronic basis is ubiquitous in the United States. As opioid receptors densely populate the gastrointestinal tract, symptoms and side effects can be expected in these patients. In the esophagus, dysmotility may result, manifesting with dysphagia and a syndrome indistinguishable from primary achalasia. In the stomach, a marked delay in gastric emptying may occur with postprandial nausea and early satiety. Postoperatively, particularly with abdominal surgery, opioid-induced ileus may ensue...

Chronic intestinal pseudo-obstruction results in clinical manifestations that resemble intestinal obstruction but in the absence of any physical obstructive process. Fabry disease is an X-linked lysosomal storage disease characterized by the dysfunction of multiple systems, including significant gastrointestinal involvement. We report the occurrence of chronic intestinal pseudo-obstruction in two unrelated patients with Fabry disease and the possible explanation of a direct relation of these two disorders. In Fabry disease, gastrointestinal symptoms occur in approximately 70% of male patients, but the frequency ranges from 19% to 69% in different series...
