Mitochondrial encephalomyopathy, lactic acidosis, and stroke-like episodes (MELAS) syndrome is a maternally inherited mitochondrial disorder that is most commonly caused by the m. 3243A>G mutation in the MT-TL1 mitochondrial DNA gene, resulting in impairment of mitochondrial energy metabolism. Although childhood is the typical age of onset, a small fraction (1-6%) of individuals manifest the disease after 40 years of age and usually have a less aggressive disease course. The clinical manifestations are variable and mainly depend on the degree of heteroplasmy in the patient's tissues and organs...

BACKGROUND & AIMS: A generalized human pacemaking syndrome, chronic atrial and intestinal dysrhythmia (CAID) (OMIM 616201), is caused by a homozygous SGO1 mutation (K23E), leading to chronic intestinal pseudo-obstruction and arrhythmias. Because CAID patients do not show phenotypes consistent with perturbation of known roles of SGO1, we hypothesized that noncanonical roles of SGO1 drive the clinical manifestations observed. METHODS: To identify a molecular signature for CAID syndrome, we achieved unbiased screens in cell lines and gut tissues from CAID patients vs wild-type controls...

Ogilvie syndrome (acute colonic pseudo-obstruction) represents a clinical condition with symptoms of colonic obstruction without a distinct mechanical factor. The damage to the neural ganglia in the intestinal wall is the most likely etiology. A 62-year man was admitted to the Emergency Department due to acute dyspnea and vomiting. The patient had not defecated for 10 days prior to admission. An angio-CT revealed dilated colon, especially its left part, up to 85 mm with gas inside its lumen. During laparotomy, extremely dilated colon was confirmed with signs of the intestinal wall necrosis...

A 47-year-old male patient without a documented past medical history was referred to Sanno Hospital because of constipation and abdominal pain, which he had had for more than 5 years. Abdominal X-ray and CT scan showed an enlarged ascending colon from the cecum to the transverse colon, without apparent mechanical obstruction. The patient was diagnosed with chronic idiopathic colonic pseudo-obstruction, and because his symptoms were resistant to medication, surgical treatment was required. Laparoscopic subtotal colectomy was performed without any complications...

Eosinophilic myenteric ganglionitis (EMG) is characterised by eosinophilic infiltration of the myenteric plexus. EMG has been rarely reported as a cause of chronic intestinal pseudo-obstruction (CIPO), and its histopathological features are not fully elucidated. We analysed seven patients with CIPO. Three of them were diagnosed with EMG and four patients were categorised as non-EMG. Clinicopathological features were similar in both groups. These features included subtle to mild lymphocytic infiltration at the myenteric ganglia/muscularis propria, loss of myenteric ganglions and interstitial cells of Cajal (ICC), and no significant findings in the mucosa...

Amyloidosis is a syndrome involving amyloid protein deposition in various organs, resulting in organ dysfunction. Symptoms of gastrointestinal amyloidosis are usually nonspecific, such as diarrhea and body weight loss. We, here, report a patient who presented to the hospital with simultaneous hematemesis, melena, and intestinal pseudo-obstruction, leading to a diagnosis of primary gastrointestinal amyloidosis based on computed tomography (CT) and endoscopic findings. CT showed diffuse wall thickening from the duodenum to the jejunum, jejunal dilation, and fluid accumulation throughout the gastrointestinal tract...

Objectives: To examine the incidence, predictors and outcomes associated with severe gastrointestinal (GI) disease in a large inception SSc cohort. Methods: SSc subjects with <2 years of disease duration were identified from two multicentre cohorts. Severe GI disease was defined as: malabsorption, hyperalimentation, pseudo-obstruction and/or ⩾10% weight loss in association with the use of antibiotics for bacterial overgrowth or oesophageal stricture. Kaplan-Meier, multivariate logistic regression and Cox proportional hazard analyses were performed to determine the cumulative incidence rate, independent clinical correlates and mortality rate associated with severe GI disease...

BACKGROUND/AIMS: When conservative methods fail, neostigmine is recommended in the pharmacological treatment of acute colonic pseudo-obstruction (ACPO). The objective of this study was to analyze the response of patients to different neostigmine protocols. MATERIALS AND METHODS: Patients diagnosed with ACPO in the intensive care unit between January 2015 and September 2017 were retrospectively studied. Either of the two neostigmine protocols, the bolus dose (BD) or continuous infusion (CI), was applied to the ACPO patients who were unresponsive to conservative treatments, and the results were analyzed...

BACKGROUND: Gastrointestinal hypomotility in people taking clozapine is common, poorly understood and potentially dangerous. It causes distress and sometimes sudden death, with greater associated morbidity than the better known adverse effect of clozapine, agranulocytosis. Neither the mechanism nor prevalence of clozapine-induced gastrointestinal hypomotility is well understood. Previous studies show clozapine impedes colon transit, likely owing to anticholinergic and anti-serotonergic properties...

PURPOSE: Acquired isolated hypoganglionosis (A-IH) is a late-onset intestinal pseudo-obstruction disorder and shows different pathophysiological findings from congenital isolated hypoganglionosis (C-IH). In this study, we retrospectively examined five cases of A-IH and investigated the features of A-IH. METHODS: Five cases of A-IH were extracted from a nationwide retrospective cohort study in 10 years, from which totally 355 cases of Allied Disorders of Hirschsprung's Disease (ADHD) were collected...

Mitochondrial neurogastrointestinal encephalopathy (MNGIE) is an autosomal recessive disorder characterized by gastrointestinal dysmotility, cachexia, ptosis, peripheral neuropathy and leukoencephalopathy. The diagnosis is often not made until 5-10 years after the onset of symptoms. MNGIE is caused by mutations in thymidine phosphorylase gene TYMP. Here, we present a 19-year-old boy with MNGIE who had a chronic intestinal pseudo-obstruction, and we describe his family history. Genetic analysis revealed a novel homozygous c...

BACKGROUND: Inositol 1,4,5-trisphosphate receptors (IP3 Rs) are a family of intracellular Ca2+ release channels located on the membrane of endoplasmic reticulum, which have been shown to play critical roles in various cellular and physiological functions. However, their function in regulating gastrointestinal (GI) tract motility in vivo remains unknown. Here, we investigated the physiological function of IP3 R1 in the GI tract using genetically engineered mouse models. METHODS: Pdgfrb-Cre mice were bred with homozygous Itpr1 floxed (Itpr1f/f ) mice to generate conditional IP3 R1 knockout (pcR1KO) mice...

PURPOSE: To compare clinical response of intermittent bolus versus continuous infusion neostigmine for acute colonic pseudo-obstruction (ACPO). Acute colonic pseudo-obstruction occurs due to reduced colonic parasympathetic activity. Neostigmine is an acetylcholinesterase inhibitor that increases frequency of smooth muscle contraction by increasing acetylcholine at autonomic nervous system synapses. Although these administration modalities have been studied separately, they have never been compared...
