Persistent cow's milk protein intolerance in infants: the changing faces of the same disease
1998
Background Recent research has shown that cow's milk protein intolerance (CMPI) often persists beyond 4 years of age. Aims To evaluate the clinical and immunological characteristics of a group of infants with persistent CMPI. Patients and methods Twelve infants (6 m, 6f) with persistent CMPI were followed up from birth until a median age of 5 years. The patients underwent CMP challenge each year to evaluate CMP-tolerance. As controls we followed 26 infants (12 m, 14 f) with CMPI that resolved within 1–2 years. Results A family history of atopic disease was found in 10/12 patients with persistent CMPI and in 10/26 controls (P < 0.01). Clinical presentation changed over time: at onset symptom…
Fecal assays detect hypersensitivity to cow's milk protein and gluten in adults with irritable bowel syndrome.
2011
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 …
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…
Whole Cow’s Milk but Not Lactose Can Induce Symptoms in Patients with Self-Reported Milk Intolerance: Evidence of Cow’s Milk Sensitivity in Adults
2021
Background: Lactose intolerance is the most frequent food intolerance, but many subjects with self-reported milk intolerance (SRMI) are asymptomatic at lactose hydrogen breath test (LHBT). The aim of this study was to evaluate the frequency of lactose intolerance in SRMI patients and their clinical characteristics. Methods: In a retrospective study, the clinical records of 314 SRMI patients (259 females, mean age: 39.1 ± 13.5 years) were reviewed; 102 patients with irritable bowel syndrome (IBS) served as controls. In a prospective study, 42 SRMI patients, negatives at the LHBT, underwent a double-blind, placebo-controlled (DBPC) whole cow’s milk challenge. Results: In the retrospective stu…
Cow's milk–protein allergy as a cause of anal fistula and fissures: A case report
1998
The amplified ELISA assay results correlate well with the standard ELISA results reported previously from our laboratory. Previously it has been necessary to use high flow samplers or long sampling times to measure airborne Fel d 1 concentrations in the range reported here.5 The amplified assay might allow measurements with very short sampling periods to better describe dose-response relationships, and may also be applied to measure airborne concentrations of allergens such as cockroach or dust mite that are airborne at very low concentrations. Our finding that Fel d 1 allergen is measurable in all samples from homes without cats confirms the ubiquitous nature of cat allergen and may help t…
Sensitization in early age to food allergens in children with atopic dermatitis
2007
Background: Clinical and laboratory evidence increasingly supports the notion that food allergy plays a role in the pathogenesis of atopic dermatitis (AD). However, the prevalence of clinically significant food hypersensitivity among children with AD remains an unanswered question. Objective: To prospectively determine the prevalence of IgE-mediated food hypersensitivity among patients referred to a dermatology department for evaluation of AD, and to analyze the clinical relevance of these sensitizations in AD. Methods: We studied 44 infants of both sexes, aged less than 12 months old, who attended the dermatology department with symptoms of AD. Compliance with Hanifin-Rajka criteria was co…
A comparison between two different in vitro basophil activation tests for gluten- and cow's milk protein sensitivity in irritable bowel syndrome (IBS…
2013
Abstract Background: The diagnosis of food hypersensitivity (FH) in adult patients with gastrointestinal symptoms, beyond the immediate IgE-mediated clinical manifestations, is very often difficult. The aims of our study were to: 1) evaluate the frequency of FH in patients with irritable bowel syndrome (IBS)-like clinical presentation; and 2) compare the diagnostic accuracy of two different methods of in vitro basophil activation tests. Methods: Three hundred and five patients (235 females, age range 18–66 years) were included and underwent a diagnostic elimination diet and successive double-blind placebo-controlled (DBPC) challenges. Two different methods of in vitro basophil activation te…
Gastroesophageal reflux and cow's milk allergy in infants: A prospective study
1996
Recent reports have suggested that gastroesophageal reflux in pediatric patients may be caused by food allergy.The aim of our study was to determine the frequency of the association of gastroesophageal reflux with cow's milk protein allergy in patients win the first year of life.We studied 204 consecutive patients (median age, 6.3 months) who had been diagnosed as having gastroesophageal reflux on the basis of 24-hour continuous pH monitoring and histologic examination of the esophageal mucosa.Clinical history suggested diagnosis of cow's milk allergy in 19 infants, and 93 others had positive test results (serum IgE anti-lactoglobulin, prick tests, circulating or fecal or nasal mucus eosino…
Food Hypersensitivity as a Cause of Rectal Bleeding in Adults
2008
Background & Aims Rectal bleeding and lymphonodular hyperplasia (LNH) in children can be caused by food hypersensitivity (FH). Our aim was to verify whether similar clinical and endoscopy presentations in adults can be due to FH. Methods Consecutive adult patients with rectal bleeding were enrolled. All underwent routine assays, colonoscopy, and histology study. Results Ten of 64 (15%) patients showed LNH as the unique sign at colonoscopy. An oligoantigenic diet resolved the rectal bleeding in 9 patients, and the reintroduction of several foods caused symptom reappearance. Double-blind placebo-controlled challenges with cow's milk and wheat protein confirmed the FH; symptoms reappeared 1–96…
The diagnostic significance of IgG cow's milk protein antibodies re-evaluated
1996
The effect of different feeding regimens, notably the use of hydrolysed cow's milk formulas, on the development of allergic reactions and the development of cow's milk protein-IgG antibodies is still disputed. We prospectively compared the development of allergic manifestations and cow's milk protein-IgG antibodies in a total of 702 infants who were divided into six groups: Cow's milk protein antibodies were determined by an indirect immuno-fluorescent test. Antibody titres rose slowly in groups 1, 3 and 6. Children in group 5 showed two high peaks. There were no significant differences in the frequency and type of allergic manifestations between the groups. Introduction of cow's milk formu…
