Food hypersensitivity in patients with irritable bowel syndrome: the diagnostic role of fecal assays.

research product

Fecal assays detect hypersensitivity to cow's milk protein and gluten in adults with irritable bowel syndrome.

Background & Aims Some patients with irritable bowel syndrome (IBS)-like symptoms suffer from food hypersensitivity (FH); their symptoms improve when they are placed on elimination diets. No assays identify patients with FH with satisfactory levels of sensitivity. We determined the frequency of FH among patients with symptoms of IBS and the ability of fecal assays for tryptase, eosinophil cationic protein (ECP), or calprotectin to diagnose FH. Methods The study included 160 patients with IBS, 40 patients with other gastrointestinal diseases, and 50 healthy individuals (controls). At the start of the study, patients completed a symptom severity questionnaire, fecal samples were assayed, and …

Mevolonate Pathway:role of bisphosphonates and statins

Cardiovascular diseases, i.e. high blood pressure, coronary heart disease, and stroke, and osteoporosis are public health problems, with several epidemiological links, and they might be related to each other in terms of pathogenesis and therapeutic agents. Bisphosphonates inhibit bone resorption and are used in the treatment of osteoporosis, whereas statins inhibit cholesterol biosynthesis and are used for the treatment of atherosclerosis and lipid metabolic disorders. Some late clinical studies suggested bisphosphonates may have beneficial effect in vivo on atherosclerotic progression, lipid profiles, and cardiovascular morbidity and mortality, whereas statins might increase bone density, …

Terapia biologica con infliximab (anti-TNF) nella malattia di Crohn: analisi delle complicanze.

Anti-tumor necrosis factor (anti-TNF) therapy is an important therapeutic addition in the treatment of active Crohn's disease. Although controlled trials have confirmed the efficacy of anti-TNF (infliximab) treatment, serious toxicities related to the therapies have emerged. The purpose of this article was to review the safety profile of infliximab, and in particular analyse the infectious complications, the autoimmune disorders and the theoretical risk of cancer and lymphoma

Low incidence but poor prognosis of complicated coeliac disease: A retrospective multicentre study.

Abstract Background Coeliac disease is a chronic enteropathy characterized by an increased mortality caused by its complications, mainly refractory coeliac disease, small bowel carcinoma and abdominal lymphoma. Aim of the study was to study the epidemiology of complications in patients with coeliac disease. Methods Retrospective multicenter case–control study based on collection of clinical and laboratory data. The incidence of complicated coeliac disease was studied among coeliac patients directly diagnosed in four Italian centres. Patients referred to these centres after a diagnosis of coeliac disease and/or complicated coeliac disease in other hospitals were therefore excluded. Results B…

A multicentre case control study on complicated coeliac disease: two different patterns of natural history, two different prognoses

Background: Coeliac disease is a common enteropathy characterized by an increased mortality mainly due to its complications. The natural history of complicated coeliac disease is characterised by two different types of course: patients with a new diagnosis of coeliac disease that do not improve despite a strict gluten-free diet (type A cases) and previously diagnosed coeliac patients that initially improved on a gluten-free diet but then relapsed despite a strict diet (type B cases). Our aim was to study the prognosis and survival of A and B cases. Methods: Clinical and laboratory data from coeliac patients who later developed complications (A and B cases) and sex- and age-matched coeliac p…

Antiendomysium antibodies assay in the culture medium of intestinal mucosa: an accurate method for celiac disease diagnosis

Background Celiac disease (CD) diagnosis is becoming more difficult as patients with no intestinal histology lesions may also be suffering from CD. Aim To evaluate the diagnostic accuracy of antiendomysium (EmA) assay in the culture medium of intestinal biopsies for CD diagnosis. Patients and methods The clinical charts of 418 patients with CD and 705 non-CD controls who had all undergone EmA assay in the culture medium were reviewed. Results EmA assay in the culture medium had a higher sensitivity (98 vs. 80%) and specificity (99 vs. 95%) than serum EmA/antibodies to tissue transglutaminase (anti-tTG) assay. All patients with CD who were tested as false-negatives for serum EmA and/or anti-…

Searching for wheat plants with low toxicity in celiac disease: Between direct toxicity and immunologic activation.

Abstract Background Natural or induced variations in the noxiousness of gluten proteins for celiac disease (CD) patients are currently being investigated for their potential in breeding wheat crops with reduced toxicity. Aims We evaluated the bread wheat line C173 for its effects on the in vitro -grown duodenal mucosa of CD patients. Methods In vitro -grown duodenal mucosa biopsies of 19 CD patients on a gluten-free diet were exposed to peptic/tryptic-digested prolamins from bread wheat line C173 lacking gliadin–glutenin subunits, analyzed for morphology, cytokine and anti-tTG antibody production, and compared with mucosa biopsies exposed to prolamins from wild-type cv. San Pastore. Results…

research product

A key role for abdominal ultrasound examination in "difficult" diagnoses of celiac disease.

Purpose To evaluate the usefulness of abdominal ultrasound examination (US) for the diagnostic workup of cases of suspected CD involving negative serum antibodies and difficult diagnosis. Materials and methods 524 consecutive patients with symptoms of suspected CD underwent an extensive diagnostic workup. 76 (14 %) were excluded since they were positive for serum anti-tTG and/or EmA antibodies. 377 were excluded since they were diagnosed with something other than CD or did not have the alleles encoding for HLA DQ 2 or DQ 8. A diagnosis of CD with negative serum antibodies was probable in 71 patients who underwent abdominal US and duodenal biopsy for histology evaluation. Results Intestinal …

A Cytologic Assay for Diagnosis of Food Hypersensitivity in Patients With Irritable Bowel Syndrome

BACKGROUND & AIMS: A percentage of patients with symptoms of irritable bowel syndrome (IBS) suffer from food hypersensitivity (FH) and improve on a food-elimination diet. No assays have satisfactory levels of sensitivity for identifying patients with FH. We evaluated the efficacy of an in vitro basophil activation assay in the diagnosis of FH in IBS-like patients. METHODS: Blood samples were collected from 120 consecutive patients diagnosed with IBS according to Rome II criteria. We analyzed in vitro activation of basophils by food allergens (based on levels of CD63 expression), as well as total and food-specific immunoglobulin (Ig)E levels in serum. Effects of elimination diets and dou…

Clinical symptoms in celiac patients on a gluten-free diet.

OBJECTIVE: Persistent villous atrophy in patients with celiac disease (CD) on a gluten-free diet (GFD) is reported with increasing frequency. The aim of this study was to evaluate a possible association between persistent damage of the villi and "atypical" gastrointestinal symptoms in CD patients on a GFD. MATERIAL AND METHODS: Sixty-nine CD patients on a GFD were divided into two groups: Group A included 42 patients (6 M, 36 F, age range 17-62 years) undergoing esophagogastroduodenoscopies (EGDs) due to the presence of symptoms; Group B included 27 control patients (6 M, 21 F, age range 24-71 years) who were asymptomatic at the time of the study. Both groups underwent EGDs and a duodenal h…

IgA anti-actin antibodies ELISA in coeliac disease: A multicentre study.

Previous studies have demonstrated that serum anti-actin antibodies are a reliable marker of intestinal damage severity in coeliac disease.To validate in a multicentre study the clinical usefulness of serum IgA anti-actin antibody ELISA and its possible use in monitoring intestinal mucosa lesions during gluten-free diet.Four centres recruited 205 newly diagnosed coeliac disease patients with villous atrophy, 80 healthy controls and 81 "disease" controls. Twelve coeliac disease patients on gluten-free diet but with persistent symptoms underwent serum IgA anti-actin antibody assay and intestinal histology evaluation. IgA anti-actin antibody ELISA was performed with a commercial kit. All coeli…
