Are food intolerances and allergies increasing in immigrant children coming from developing countries ?

2006

There are not available data concerning the occurrence, the clinical features and the environmental risk factors for food intolerances and allergies in immigrant children. The aim of the study was to evaluate rates, distribution, clinical features and environmental risk factors for food intolerances and allergies in immigrant children. Hospital records of 4,130 patients with celiac disease (CD), cow milk protein intolerance (CMPI) and food allergies (FA) diagnosed in 24 Italian Centres from 1999 to 2001 were retrospectively reviewed, comparing immigrant patients with Italian ones. 78/4,130 (1.9%) patients were immigrant: 36/1,917 (1.9%) had CD, 24/1,370 (1.75%) CMPI and 18/843 (2.1%) FA.

Steatocrit test: Normal range and physiological variations in infants

1990

In order to define the normal values of steatocrit during the first 3 months of life and the normal correlation between fecal fat content and steatocrit values, 60 full-term healthy unweaned infants (30 bottle-fed, 15 breast-fed, and 15 mixed-fed) were studied. The steatocrit micromethod was performed in these babies at 7, 14, 21, 28, 45, and 90 days after birth. Steatorrhea often occurs during the first month and then decreases, as shown by the fall in the steatocrit curve from 7th to 28th day in our subjects; at 45 days, few babies have steatorrhea. The 90th percentile profile of steatocrit values shows a value of 25% at the first week of life and a value of 13% at the fourth week. After …

Diagnostic efficacy of the ELISA test for the detection of deamidated anti-gliadin peptide antibodies in the diagnosis and monitoring of celiac disea…

2009

Background and Aim: We evaluated the diagnostic performance of an ELISA test for anti-gliadin IgA and IgG antibodies, which uses synthetic deamidated gliadin peptides (anti-gliadin antibodies, AGAs) as coating; the results were compared with a test that uses extracted gliadin (AGAe). Methods: The study was conducted on the sera of 144 patients suffering from celiac disease (CD), including 20 patients with IgA deficiency and 9 who were following a gluten-free diet (GFD), and 129 controls. Results: In the 115 CD patients (without IgA deficiency), the sensitivity of AGAe IgA and IgG was 32.2 and 60.9%, whereas that of AGAs IgA and IgG was 59.1 and 72.2%. The specificity for AGAe IgA and IgG, a…

Exocrine pancreatic function in children with coeliac disease before and after a gluten free diet.

1991

This study was designed to determine the extent of pancreatic insufficiency in untreated coeliac disease and whether pancreatic secretion is impaired after a prolonged gluten free period. Three groups of patients were studied: group A comprised 44 patients, mean (SD) age 4.0 (3.1) years, with coeliac disease and total or subtotal atrophy of the intestinal mucosa; group B comprised 67 patients, mean age 4.4 (3.0) years, with coeliac disease but with normal morphology of the intestinal villi (after 12.9 months of a gluten free diet); group C comprised 49 control subjects, mean age 3.2 (3.0) years, with normal jejunal histology. In all subjects exocrine pancreatic function was determined by th…

Low Prevalence of Celiac Disease among Patients with Functional Gastrointestinal Disorders in Latvia.

2020

Background and Aims: Studies suggest that the prevalence of celiac disease (CD) is increased in individuals with functional gastrointestinal disorders (FGIDs), in particular, irritable bowel syndrome (IBS); however, the evidence is conflicting. We aimed to analyze the prevalence of CD in patients with FGIDs in Latvia.
 Methods: This retrospective study included patients with FGIDs, referred for a gastroenterologist consultation in a secondary gastroenterology practice unit. Patients were divided into three groups – patients only with IBS (IBS group), patients only with functional dyspepsia (FD) (FD group), patients with mixed symptoms IBS and FD (Mixed group). Patient levels of tissue …

Steatocrit test after a standard fatty meal: A new simple and sensitive test to detect malabsorption

1991

The steatocrit test, a simple semiquantitative method for determining fat content in stool, was performed after a standard fatty meal to detect malabsorption in patients with celiac disease. Thirty-seven children (mean age 2.6 +/- 2.1 years) with total atrophy of the intestinal villi and 79 controls (mean age 3.5 +/- 2.8 years) were studied. All subjects underwent a small-bowel biopsy, a D-xylose absorption test, a rapid triglyceride absorption test, and a steatocrit determination first on an uncontrolled diet and then again after a standard fatty meal. The steatocrit test after a fatty meal did not detect any false-positive or false-negative results, while the D-xylose test showed two fals…

Coeliac disease: Oral ulcer prevalence, assessment of risk and association with gluten-free diet in children.

2008

Aims. Oral mucosal lesions may be markers of chronic gastrointestinal disorders, such as those causing malabsorption. Our objectives were to assess the prevalence of recurrent oral aphthous-like ulcers in coeliac disease patients living in the Mediterranean area, and to evaluate the impact of a gluten-free diet. Methods. A test group of 269 patients (age range 3-17 years) with coeliac disease confirmed both serologically and histologically was compared with a control group of 575 otherwise clinically healthy subjects for the presence, or a positive history of aphthous-like ulcers. Coeliac disease patients with aphthous-like ulcers were re-evaluated 1-year after starting a gluten-free diet. …

Use of famotidine in severe exocrine pancreatic insufficiency with persistent maldigestion on enzymatic replacement therapy. A long-term study in cys…

1992

In patients with pancreatic exocrine insufficiency, the use of pancreatic enzyme does not abolish steatorrhea in some cases. We carried out a long-term prospective study in an attempt to clarify the effectiveness of the associated use of famotidine to enzymatic supplementation on fat absorption and nutritional parameters of patients with pancreatic insufficiency due to cystic fibrosis. We studied 10 patients, mean age 12.5 years, with persistent steatorrhea on enzymatic supplementation. A double-blind crossover design was used and famotidine (1 mg/kg/day) or placebo was given as adjuvant to enzymatic preparations for either of two six-month periods. A statistically significative reduction i…

Role of pancreatic impairment in growth recovery during gluten-free diet in childhood celiac disease

1997

Abstract BACKGROUND & AIMS: Clinical significance and duration of insufficient release of pancreatic enzymes in childhood celiac disease have not been clarified. The aim of this study was to evaluate the role that pancreatic impairment plays in growth recovery and the duration of this impairment. METHODS: Forty-six patients with celiac disease who had a median age of 2.5 years were enrolled. Fecal chymotrypsin level was determined at diagnosis and then every 15 days after the beginning of a gluten-free diet in all patients. RESULTS: At diagnosis, 17 of 46 patients with celiac disease had subnormal fecal chymotrypsin values. During the gluten-free diet, a progressive reduction in the percent…
