"Geographical distribution of risk genotypes in pediatric patients with celiac disease in Spain".

Celiac disease is strongly associated with HLA DQ, specifically with haplotypes. DRB1*03-DQA1*05:01/DQB1*02:01 (DQ2.5),DRB1*07-DQA1*02:01/DQB1*02:02 (DQ2.

Correlation of Anti-Tissue Transglutaminase Antibodies With the Mucosal Changes and IgA Status of Children With Celiac Disease.

Objectives: The objective of this study was to assess the association between serological markers and changes of the intestinal mucosa in children with celiac disease (CD).

Methods: Clinical data from CD patients under 15 years old were collected from the participating centers in an on-line multicenter nationwide observational Spanish registry called REPAC-2 (2011-2017). Correlation between anti-tissue transglutaminase antibodies (t-TGA) levels and other variables, including mucosal damage and clinical findings (symptoms, age, and gender), was assessed.

Prospective longitudinal study: use of faecal gluten immunogenic peptides to monitor children diagnosed with coeliac disease during transition to a gluten-free diet.

Background: Treatment for coeliac disease is a lifelong strict gluten-free diet. Although guidelines recommend regular follow-up with dietary interviews and coeliac serology, these methods may be inaccurate.

Aim: To evaluate the usefulness of faecal gluten immunogenic peptides to support the diagnosis and to determine the adherence to the gluten-free diet in coeliac children.

Fecal Gluten Peptides Reveal Limitations of Serological Tests and Food Questionnaires for Monitoring Gluten-Free Diet in Celiac Disease Patients.

Objectives: Treatment for celiac disease (CD) is a lifelong strict gluten-free diet (GFD). Patients should be followed-up with dietary interviews and serology as CD markers to ensure adherence to the diet. However, none of these methods offer an accurate measure of dietary compliance.

ESPGHAN 2012 Guidelines for Coeliac Disease Diagnosis: Validation Through a Retrospective Spanish Multicentric Study.

Objectives: A large retrospective multicentre study was conducted in Spain to evaluate the efficiency of the new European Society for Pediatric Gastroenterology, Hepatology, and Nutrition (ESPGHAN) criteria for the diagnosis of coeliac disease (CD).

Methods: The study protocol was approved by the ethics committee of Hospital Universitari i Politècnic La Fe (Valencia, Spain). The present study included 2177 children (ages 0.

Spanish national registry of celiac disease: incidence and clinical presentation.

Objectives: The aim of this study was to assess the incidence and clinical pattern of celiac disease (CD) presently diagnosed in Spanish children.

Methods: A prospective, multicenter, nationwide registry of new cases of CD in children <15 years was conducted from June 1, 2006 to May 31, 2007. The parameters studied were age at diagnosis, sex, clinical symptoms, associated diseases, nutritional status, CD serology, histological lesions, and HLA-DQ2/-DQ8.

Influence of breastfeeding versus formula feeding on lymphocyte subsets in infants at risk of coeliac disease: the PROFICEL study.

Purpose: In addition to genetic risk, environmental factors might influence coeliac disease (CD) development. We sought to assess the effect of the interaction between milk-feeding practices and the HLA-DQ genotype on peripheral lymphocyte subsets and their activation markers in infants at familial risk for CD.

Methods: 170 newborns were classified in 3 different genetic risk groups (high risk, HR; intermediate risk, IR; and low risk, LR) after DQB1 and DQA1 typing.

Influence of milk-feeding type and genetic risk of developing coeliac disease on intestinal microbiota of infants: the PROFICEL study.

Interactions between environmental factors and predisposing genes could be involved in the development of coeliac disease (CD). This study has assessed whether milk-feeding type and HLA-genotype influence the intestinal microbiota composition of infants with a family history of CD. The study included 164 healthy newborns, with at least one first-degree relative with CD, classified according to their HLA-DQ genotype by PCR-SSP DQB1 and DQA1 typing.

Influence of environmental and genetic factors linked to celiac disease risk on infant gut colonization by Bacteroides species.

Celiac disease (CD) is an immune-mediated enteropathy involving genetic and environmental factors whose interaction might influence disease risk. The aim of this study was to determine the effects of milk-feeding practices and the HLA-DQ genotype on intestinal colonization of Bacteroides species in infants at risk of CD development. This study included 75 full-term newborns with at least one first-degree relative suffering from CD.

Celiac disease screening by immunochromatographic visual assays: results of a multicenter study.

Objective: To assay the efficiency for celiac disease (CD) screening of 2 immunochromatographic visual stick assays based on human recombinant tissue transglutaminase (tTG). One was the antitissue transglutaminase antibodies (AtTGA) stick for IgA/G antibodies to tTG detection, the other was the AtTGA/antigliadin antibodies (AGA) stick for IgA antibodies for tTG and/or gliadins.

Patients And Methods: In a prospective multicenter study, 4 pediatric gastroenterology units from Spain and 2 from Latin America enrolled 72 control children with a normal small bowel mucosa and 113 untreated patients with CD with Marsh type 3 lesions.

Immunochromatographic sticks for tissue transglutaminase and antigliadin antibody screening in celiac disease.

Background & Aims: We investigated two 1-step immunochromatographic visual assays based on human recombinant tissue-transglutaminase (t-TG) as an alternative to enzyme-linked immunosorbent assays (ELISAs) for celiac disease (CD) screening.

Methods: We used a tissue-transglutaminase (t-TG) stick, which detected immunoglobulin A/G (IgA/G) antibodies to t-TG, and a t-TG/antigliadin antibodies (AGA) stick, which detected IgA antibodies to both t-TG and AGA, as well as t-TG and AGA ELISAs, to determine t-TG and AGA antibodies in untreated celiac patients with subtotal villous atrophy. A total of 142 children (3 IgA-deficient sera) and 30 adults, and 140 controls (normal mucosa; 121 children and 19 adults), plus 23 sera from pediatric CD patients in remission were assayed.
