OBJECTIVE Irritable bowel syndrome (IBS) is a common gastrointestinal disorder with clinical signs typical of "intestinal" food allergies or intolerance. The aim of this study was to characterize the clinical features of IBS patients suspected of suffering from adverse reactions to food. METHODS The study involved 128 consecutive IBS patients divided into(More)
The effect of baking and digestion on the allergenicity of wheat flour proteins has been studied. Pooled sera of patients suffering from food allergy to wheat products were tested for IgE binding to the proteins of the wheat dough and of the bread crumb and crust, before and after being in vitro digested. During in vitro digestion, the IgE binding protein(More)
UNLABELLED Coeliac disease is an autoimmune enteropathy characterized by an enhanced permeability of the intestinal epithelial barrier. In epithelial cells paracellular permeability is regulated by intercellular tight junction. The cytoplasmic protein ZO-1 interacts directly with F-actin and plays a pivotal role in the structural and functional organization(More)
Humoral immune mechanisms may have a role in the neurological complications of celiac disease (CD). We assessed 71 CD patients for neurologic manifestations and presence of serum antibodies to neural antigens. Sixteen patients (22.5%) were found to have neurological deficits including headache, depression, entrapment syndromes, peripheral neuropathy, and(More)
Antibodies to gangliosides and Purkinje cells have been reported in patients with celiac disease (CD) with neuropathy and ataxia, respectively. Whether these antibodies are pathogenic is not clear. The response of neurological symptoms and antibody titers to a gluten-free diet is still controversial. The objective of our study was to assess whether(More)
BACKGROUND Helicobacter pylori is thought to be involved in atrophic body gastritis. We explored the prevalence of H. pylori infection in asymptomatic subjects with gastric parietal cell antibodies, as well as in patients with pernicious anemia, to evaluate a possible role of H. pylori gastric infection in gastric autoimmunity. PATIENTS AND METHODS We(More)
Acquired copper deficiency has recently been recognized as a cause of myeloneuropathy mimicking subacute combined degeneration due to vitamin B-12 deficiency. A remote history of gastric surgery is frequently associated with this syndrome. However, the very limited prevalence of severe copper deficiency in patients with a history of gastric surgery suggests(More)
Colitis cystica profunda is a rare intestinal lesion. Because of its clinical expression (rectorrhagia, mucorrhea and abdominal pain) and the way it appears to current imaging techniques this disease presents features which can be associated with colon neoplasm. Its diagnosis has to be confirmed histologically, and its etiology remains unclear. The(More)
OBJECTIVES This study investigated the relationship between participants' expected levels of pain intensity before a colonoscopy, pain intensity experienced while they were undergoing this medical procedure (real-time pain), and their retrospective evaluation of this experience. DESIGN Correlational design. Regression analyses were performed and(More)
