BACKGROUND Gastroesophageal reflux disease (GERD), including erosive reflux disease and non-erosive reflux disease (NERD), is a chronic disease with a significant negative effect on quality of life. State-of-the-art treatment involves proton pump inhibitors (PPIs). However, relapse of symptoms occurs in the majority of the patients who require recurrent or(More)
In the central nervous system glial-derived S100B protein has been associated with inflammation via nitric oxide (NO) production. As the role of enteroglial cells in inflammatory bowel disease has been poorly investigated in humans, we evaluated the association of S100B and NO production in ulcerative colitis (UC). S100B mRNA and protein expression,(More)
Functional dyspepsia is a highly prevalent symptom complex and a heterogenous disorder. Recent studies showed potential associations between specific pathophysiologic disturbances and dyspeptic symptoms. Delayed gastric emptying reported in about 30% of patients with functional dyspepsia is associated with the symptoms of postprandial fullness, nausea, and(More)
Chronic intestinal pseudo-obstruction (CIP) represents a particularly difficult clinical challenge. It is a rare and highly morbid syndrome characterised by impaired gastrointestinal propulsion together with symptoms and signs of bowel obstruction in the absence of any lesions occluding the gut lumen. CIP can be classified as either "secondary" to a wide(More)
BACKGROUND Diverticular disease (DD) and irritable bowel syndrome (IBS) share a similar symptom pattern. However, comparative studies are flawed by different age at onset of symptoms. We aimed to verify whether clinical features distinguish DD from IBS. MATERIALS AND METHODS Patients with DD or IBS, matched for age and gender (1/1) were consecutively(More)
After a meal, the proximal stomach relaxes probably through the activation of nitrergic neurons in the gastric wall. Nitric oxide-induced smooth muscle relaxation involves activation of soluble guanylate cyclase, with cGMP production, which is then degradated by phosphodiesterase-5 (PDE-5). The aim of this study was to investigate the effect of sildenafil,(More)
OBJECTIVES Nicotinamide methylation followed by urinary excretion of N-methylnicotinamide increases in cirrhotic patients, despite the derangement of the overall methylation processes in liver disease. The rise in N-methylnicotinamide could depend, at least in part, on a reduced transformation of this molecule into 2-pyridone-5-carboxamide. The aim of this(More)
BACKGROUND & AIMS Enteric glia participates to the homeostasis of the gastrointestinal tract. In the central nervous system, increased expression of astroglial-derived S100B protein has been associated with the onset and maintaining of inflammation. The role of enteric glial-derived S100B protein in gastrointestinal inflammation has never been investigated(More)
Enteric glial cells (EGC) actively mediate acute and chronic inflammation in the gut; EGC proliferate and release neurotrophins, growth factors, and pro-inflammatory cytokines which, in turn, may amplify the immune response, representing a very important link between the nervous and immune systems in the intestine. Cannabidiol (CBD) is an interesting(More)
BACKGROUND Patients with chronic renal failure (CRF) often have dyspeptic symptoms and may develop peptic disease or digestive disorders leading to severe gastrointestinal complications. The primary aim of this study was to evaluate the prevalence of peptic lesions and Helicobacter pylori infection, and the severity of dyspeptic symptoms, in dyspeptic(More)
