Food intolerance and chronic constipation: manometry and histology study

2006

BACKGROUND: Chronic constipation in children can be caused by cows' milk intolerance (CMI), but its pathogenesis is unknown. AIMS: To evaluate the histology and manometry pattern in patients with food intolerance-related constipation. PATIENTS AND METHODS: Thirty-six consecutive children with chronic constipation were enrolled. All underwent an elimination diet and successive double-blind food challenge. All underwent rectal biopsy and anorectal manometry. RESULTS: A total of 14 patients were found to be suffering from CMI and three from multiple food intolerance. They had a normal stool frequency on elimination diet, whereas constipation recurred on food challenge. The patients with food i…

Chronic constipation and food intolerance: A model of proctitis causing constipation

2005

OBJECTIVE: Chronic constipation in children can be linked to cow''s milk intolerance (CMI) but the existence of a food intolerance-dependent proctitis is still debated. The aim of this study was to evaluate the histologic data in patients with food intolerance-related constipation. MATERIAL AND METHODS: Fifty-two consecutive patients (22 M, median age 4 years) with chronic constipation unresponsive to common treatment were enrolled. All patients were put on a cow''s milk-free diet for 4 weeks and those uncured on this diet underwent a subsequent 4-week period of oligoantigenic diet. In the patients cured on elimination diet, a subsequent double-blind food challenge was performed to confirm …

Diagnostic Accuracy of Fecal Calprotectin Assay in Distinguishing Organic Causes of Chronic Diarrhea from Irritable Bowel Syndrome: A Prospective Stu…

2003

AbstractBackground: Fecal calprotectin (FC) has been proposed as a marker of inflammatory bowel disease (IBD), but few studies have evaluated its usefulness in patients with chronic diarrhea of various causes. We evaluated the diagnostic accuracy of a FC assay in identifying “organic” causes of chronic diarrhea in consecutive adults and children.Methods: We consecutively enrolled 70 adult patients (30 males, 40 females; median age, 35 years) and 50 children (20 males, 30 females; median age, 3.5 years) with chronic diarrhea of unknown origin. All patients underwent a complete work-up to identify the causes of chronic diarrhea. FC was measured by ELISA.Results: In adult patients, FC showed 6…

Proctitis and constipation: A symptom of food allergy?

2015

Abstract Allergic proctitis can occur in infants and children. It is expressed by feces streaked with blood without other apparent signs. More than 50% of these patients are being breast-fed. Recently, it has been found that a particular symptom of allergic proctitis is constipation, and it is a major cause of consultations in pediatric gastroenterology departments. We carried out a study, which included a series of patients who were seen for chronic constipation that had not responded to the usual therapy. We found that the majority of these patients had a reduction in the layer of mucus coating the rectum, and this sign was associated with intolerance to cow's milk protein and also to oth…

Unexplained Elevated Serum Pancreatic Enzymes: A Reason to Suspect Celiac Disease

2006

BACKGROUND & AIMS: The frequency of elevated serum pancreatic enzymes in patients with celiac disease (CD) is unknown. The aim of this study was to evaluate the serum levels of pancreatic enzymes in CD patients. METHODS: Serum pancreatic isoamylase and lipase levels were assayed in 90 adult and 112 pediatric consecutive CD patients at diagnosis and after 12 months of gluten-free diet (GFD). Serum elastase and trypsin levels were assayed in a subgroup of adult CD patients. Pancreatic ultrasonography was also performed. RESULTS: Twenty-six adult (29%) and 29 pediatric (26%) CD patients exhibited elevated values of serum pancreatic amylase and/or lipase; trypsin was elevated in 69% and elastas…

The "red umbilicus": a diagnostic sign of cow's milk protein intolerance

2006

Introduction: Red umbilicus is considered to be an infectious disease typical of neonates. In our experience, umbilical erythema could be due to cow's milk protein intolerance (CMPI). Aims: To evaluate the frequency and clinical significance of umbilical erythema in a series of consecutive children referred for suspected CMPI. Patients and Methods: Seven hundred ninety-six consecutive patients (median age, 18 months) referred for suspected CMPI diagnosis were studied. CMPI diagnosis was based on the disappearance of symptoms on elimination diet and their subsequent reappearance on double-blind placebo-controlled cow's milk challenge. Results: CMPI was diagnosed in 384 patients: 120 with res…

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

2007

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…

Gastrointestinal symptoms in infancy: A population-based prospective study

2005

Abstract Background. During the first months of life, infants can suffer from many ‘minor’ gastroenterological disturbances. However, little is known about the frequency of these problems and the factors which predispose or facilitate their onset. Aims. (a) To ascertain the frequency of the most common gastrointestinal symptoms in infants during the first 6 months after birth; (b) to evaluate the influence of some variables on the onset of the symptoms. Study design and patients. Each of the 150 paediatricians distributed throughout Italy followed 20 consecutive infants from birth to 6 months. 2879 infants (1422 f, 1457 m) concluded the study. The presence of the following symptoms was eval…

Anti-Transglutaminase Antibody Assay of the Culture Medium of Intestinal Biopsy Specimen Can Improve the Accuracy of Celiac Disease Diagnosis.

2006

BACKGROUND: We measured anti-transglutaminase (anti-tTG) antibody in the culture medium of intestinal biopsy specimens from patients with suspected celiac disease (CD) and evaluated the relationship between antibody production and severity of intestinal mucosal damage. METHODS: We performed diagnostic testing for CD on 273 consecutive patients. In addition to routine histologic evaluation of duodenal biopsy specimens, we assayed anti-tTG antibodies in serum and in the culture medium of duodenal biopsy specimens. RESULTS: CD was diagnosed in 191 of the 273 patients. Sensitivity and specificity of the serum anti-endomysium (EmA) and anti-tTG assays were 83% and 85% and 99% and 95%, respective…
