Gluten-free diet for pediatric patients with coeliac disease: A position paper from the ESPGHAN gastroenterology committee, special interest group in coeliac disease.

BACKGROUND AND OBJECTIVE: Coeliac disease is a chronic, immune-mediated disorder for which the only treatment consists of lifelong strict adherence to gluten-free diet (GFD). However, there is a lack of evidence-based guidelines on the GFD dietary management of coeliac disease. This position paper, led by the Special Interest Group in coeliac disease of the European Society of Pediatric, Gastroenterology Hepatology, and Nutrition, supported by the Nutrition Committee and the Allied Health Professionals Committee, aims to present evidence-based recommendations on the GFD as well as how to support dietary adherence. METHODS: A wide literature search was performed using the MeSH Terms: "diet, gluten free," "gluten-free diet," "diets, gluten-free," "gluten free diet," and "coeliac disease" in Pubmed until November 8th, 2022. RESULTS: The manuscript provides an overview of the definition of the GFD, regulations as basis to define the term "gluten-free," which foods are naturally gluten-free and gluten-containing. Moreover, it provides recommendations and educational tips and infographics on suitable food substitutes, the importance of reading food labels, risk of gluten cross-contact at home and in public settings, nutritional considerations as well as factors associated to dietary adherence based on available evidence, or otherwise clinical expertise. CONCLUSIONS: This position paper provides guidance and recommendations to support children with coeliac disease to safely adhere to a GFD.

The Gluten-Free Diet for Celiac Disease: Critical Insights to Better Understand Clinical Outcomes.

The gluten-free diet (GFD) remains a complex paradigm in managing celiac disease (CeD) in children and adults, and there are many reasons why GFD adherence should be strict to improve outcomes. However, this is a challenging task for patients, since they need to have access to quality healthcare resources that facilitate optimal GFD adherence. Understanding the strengths and weaknesses of the GFD, tackling coexisting nutritional deficiencies, and dealing with complex situations, such as seronegative CeD or non-responsive CeD, all require the involvement of a multidisciplinary team. The short- and long-term follow-up of CeD patients should preferably be performed by a combined Gastroenterology and Nutrition service with well-defined quality standards and the multidisciplinary involvement of physicians, nurses, dietitians, and psychologists. Nutritional advice and counseling by an experienced dietitian can reduce the costs associated with long-term follow-up of CeD patients. Likewise, psychological interventions may be essential in specific scenarios where implementing and sustaining a lifelong GFD can cause a significant psychological burden for patients. This manuscript aims to provide guidelines to improve clinical practice in the follow-up and monitoring of CeD patients and provide information on the nutritional risks of an ill-advised GFD. Clinicians, biochemists, food technologists, dietitians, and psychologists with a global view of the disease have been involved in its writing.

Ethical Considerations Within the ESPGHAN Community.

There are limited data on ethical issues related to the daily practice of members of the European Society for Pediatric Gastroenterology Hepatology and Nutrition (ESPGHAN). The role of the ESPGHAN Ethics Committee (EC) is to provide advice on such matters to its members. The present survey aimed to evaluate the current function, and reasons that ESPGHAN members consulted the ECs. One hundred and five participants from 24 different countries answered the questionnaire. Thirty-five point seven percent of the participants used the ESGHAN EC to ask about clinical practice problems and patient-related issues whereas 21.4% ask about human research questions. An important additional finding was that 66.3% of respondents consulted their hospital's EC when they had ethical concerns and 17.4% consulted with other colleagues with expertise. This is the first survey in the ESPGHAN and Europe that analyses ethical issues that are important to members of the National Societies for Pediatric Gastroenterology Hepatology and Nutrition.

Implementación del diagnóstico molecular del VPH: experiencia chilena en curso / Molecular diagnosis of human papillomavirus infection: the Chilean experience

Cervical Cancer (CaCu) has a heterogeneous epidemiological behavior throughout the planet, depending on regional socioeconomic development level. Some developed countries predict a potential eradication of this cancer in the next 100 years, while in Chile it still constitutes a pending challenge. Incidence rates show a slow but sustained downward prob, however, mortality has continued to fluctuate between 500-600 cases per year. A few years ago, vaccination against Human Papillomavirus (HPV), the main causal agent for this tumor, was consolidated as a public policy, both in girls and in boys. However, the technological leap in the screening prob was pending, from cytology to molecular diagnosis of the agent (HPV). In this report, we update our most recent data (2018) regarding CaCu mortality, then review global guidelines and experiences in HPV screening. Finally, we offer an account of the strategies that our health system is promoting to address the screening of the disease and whose molecular approach generates the widest worldwide scientific consensus. We also recognize the main barriers and future challenges, which, if overcome, would allow us to be in line with the mandate of WHO to control this women's health problema.

Analysis of gluten immunogenic peptides in feces to assess adherence to the gluten-free diet in pediatric celiac patients.

PURPOSE: In celiac disease (CD) there is a need for precise and non-invasive tools to assess dietary compliance to the gluten-free diet (GFD). Our aim is to evaluate the efficacy of the detection of gluten immunogenic peptides (GIP) in feces, to monitor in real life, the adherence to GFD in pediatric patients with CD. METHODS: A cross-sectional, prospective study was conducted. Fecal samples from CD children were analyzed by a rapid immunochromatographic (IC) test and by an ELISA method, both based on the antigliadin 33-mer monoclonal antibody. RESULTS: Group 1 comprises 43 children on a GFD. According to the food records (FR), 39/43 patients were compliant with the GFD and gluten consumption was recorded in 4. GIP were detected in 15/43 individuals by the ELISA method and also in 7 by IC strips. Group 2: comprise 18 children at CD diagnosis; GIP levels decreased over time (p < 0.001) in a non-linear way (p = 0.028) after starting a GFD and were below the detection limit on the third day in most individuals. CONCLUSION: GIP were detected, both by ELISA and by IC strips, in CD patients on a GFD, in which no consumption of gluten had been registered on the FR, confirming GIP detection to be superior to FR discovering involuntary transgressions. Despite a positive correlation between the amount of gluten intake and the concentration of GIP in feces, the interindividual variations observed suggest gastrointestinal factors influencing GIP recovery need to be further investigated.

Management of non-invasive tumours, benign tumours and breast cancer during the COVID-19 pandemic: recommendations based on a Latin American survey.

INTRODUCTION: The COVID-19 pandemic has changed health systems across the world, both in general hospitals and in oncology institutes or centres.For cancer specialists, particularly breast cancer (BC), the COVID-19 pandemic represents a combination of challenges since the hospital resources and staff have become more limited; this has obliged oncology specialists to seek a consensus and establish which patients with BC require more urgent attention and which patients can wait until there is a better control of this pandemic. The health system in Latin America has some special characteristics; in some of the countries, there are shortages which limit access to several specialities (surgery, clinical oncology and radiotherapy) in some regions. OBJECTIVE: After a systematic review of the most recent literature regarding the management of BC during the COVID-19 pandemic, the main objective is to understand the position of the different Latin American Societies of Mastology in terms of available alternatives for the treatment of BC. METHODS: After carrying out a comprehensive and exhaustive search of the most recent guides on the management of BC during the COVID-19 pandemic, the board members of the Latin American Federation of Mastology invited, via email, different specialists, all experts in BC care, to complete an anonymous survey online.The survey was distributed between 30 and 10 May 2020. The survey included 27 questions on four topics: demographic information, consultations, imaging and treatment of BC.The questionnaire was sent and then distributed to various health specialists including breast surgeons, clinical oncologists, radiation oncologists and radiologists via the Presidents of the different Latin American Societies of Mastology in 18 countries. The results are summarised as tallies based on the number of responses to each question. RESULTS: A total of 499 responses were received. The majority of the respondents were males (275 (55.11%)); 290 participants were over 45 years (58.11%).The questionnaire presented those surveyed with three possible answers (agree, disagree and neither agree nor disagree). The results reflect that there was consensus in the majority of situations presented. Only seven questions revealed disagreement among those responding. The results are presented as recommendations. CONCLUSION: The management of patients with BC presents unique challenges during the current world health situation produced by COVID-19 pandemic. Breast care specialists (surgical oncologists, breast care clinicians, clinical oncologists, radiation oncologists and radiologists) from 18 countries in Central and South America submitted through their responses and recommendations for the treatment of BC during the COVID-19 pandemic.

Desafío hospitalario: experiencia de un equipo de ginecología en el manejo integral de pacientes COVID 19 / A hospital challenge: experience of a gynecology team in the comprehensive management of patients COVID 19

INTRODUCCIÓN: La infección por el coronavirus SARS-CoV2 (COVID 19), causal de la pandemia actual, ha significado a nivel mundial la hospitalización simultánea de múltiples pacientes poniendo a prueba la infraestructura hospitalaria y la capacidad de reacción del personal de salud. Una de las estrategias para el manejo es la reconversión de camas y servicios clínicos. OBJETIVOS: presentar experiencia de un equipo ginecológico en el manejo integral de pacientes no gineco-obstétricas con COVID 19, durante el mes de junio de 2020 en un hospital público de la Región Metropolitana. MÉTODOS: Estudio de corte transversal observacional, descriptivo. Se consideró el total de pacientes adultos hombres y mujeres sin patología gineco-obstétrica con COVID 19 ingresados al puerperio del Hospital Santiago Oriente, obteniéndose datos clínicos y demográficos a través del registro interno de la unidad y del sistema de información de red asistencial. RESULTADOS: Ingresaron 82 pacientes, 32 mujeres y 50 hombres, promedio de edad 64. El promedio de días de hospitalización fue 5, con diagnóstico de ingreso principal neumonía viral por COVID-19. Las comorbilidades frecuentes fueron hipertensión arterial sistémica y diabetes mellitus. La complicación más frecuente fue el tromboembolismo pulmonar agudo. Hubo una alta cobertura de entrega de información vía telefónica a familiares. De los 82 ingresos, 54 pacientes egresaron a su domicilio. El resto a otras unidades dentro de la institución, centros de menor complejidad o residencias sanitarias. Una paciente sexo femenino de 75 años fallece a causa de descompensación de patologias de base secundario a neumonia por Staphylococus aereus. En ella, se descarta la infección por COVID 19 dado tres exámenes por reacción de polimerasa en cadena negativos realizado antes y durante su hospitalización. CONCLUSIONES: Esta experiencia constituyó un desafío para todo el equipo de salud gineco-obstétrico, considerando que nos enfrentamos a otro tipo de pacientes y a una patología nueva. Los resultados médicos son promisorios, la experiencia humana y sentido de trabajo en equipo fue extraordinario.

INTRODUCTION: The infection by the SARS-CoV2 coronavirus (COVID 19), the cause of the current pandemic we are experiencing, has meant the simultaneous hospitalization of many patients worldwide, putting the hospital infrastructure and the reaction capacity of health personnel to the test. One of the management strategies is the reconversion of clinical services. OBJECTIVES: present the experience of a gynecological team in the comprehensive management of non-gyneco-obstetric patients with COVID 19, during the month of June 2020 in a public hospital in the Metropolitan Region. METHODS: descriptive, observational cross-sectional study. The total number of patients admitted to the ex-puerperium of the Santiago Oriente Hospital was considered, obtaining clinical and demographic data through the unit's internal registry and the healthcare network information system. RESULTS: 82 patients were admitted, 32 women and 50 men, average age 64. The average number of days of hospitalization was 5, with the main admission diagnosis being viral pneumonia due to COVID-19. Frequent comorbidities were systemic arterial hypertension and diabetes mellitus. The most frequent complication was acute pulmonary thromboembolism. There was a high coverage of the delivery of information via telephone to relatives. Of the 82 admissions, 54 patients were discharged home and the rest to other units within the institution, less complex centers or health residences. One 75 years old female patient dies from concomitant pathologies, and she wasn't positive for COVID-19. CONCLUSIONS: This experience was a challenge for the entire gynecological-obstetric health team, considering that we are facing other types of patients and a new pathology. The medical results are promising, the human experience and sense of teamwork was extraordinary.

Growth rate of coeliac children is compromised before the onset of the disease.

INTRODUCTION: Growth impairment has often been described in children who develop coeliac disease (CD). Based on data from the multicentre, longitudinal PreventCD study, we analysed the growth patterns of infants at genetic risk of CD, comparing those who developed CD by 6 years of age (CD 'cases', 113 infants) versus those who did not develop CD by 6 years (no CD 'controls', 831 infants). METHODS: Weight and length/height were measured using a longitudinal protocol. Raw measurements were standardised, computing z-scores for length/height and weight; a linear mixed model was fitted to the data in order to compare the rate of growth in the two cohorts. RESULTS: Neither cases nor controls had significant growth failure. However, when the mean z-scores for weight and height were analysed, there was a difference between the two groups starting at fourth month of life. When the growth pattern in the first year was analysed longitudinally using mixed models, it emerged that children who develop CD had a significantly lower growth rate in weight z-score (-0.028/month; 95% CI -0.038 to -0.017; p<0.001) and in length/height z-score (-0.018/month; 95% CI -0.031 to -0.005; p=0.008) than those who do not develop CD. When the whole follow-up period was analysed (0-6 years), differences between groups in both weight and length/height z-scores were confirmed. CONCLUSION: The growth of children at risk of CD rarely fell below 'clinical standards'. However, growth rate was significantly lower in cases than in controls. Our data suggest that peculiar pathways of growth are present in children who develop CD, long before any clinical or serological signs of the disease appear.

Clinical validation of an evidence-based method to adjust Pancreatic Enzyme Replacement Therapy through a prospective interventional study in paediatric patients with Cystic Fibrosis.

BACKGROUND: A method to adjust Pancreatic Enzyme Replacement Therapy in Cystic Fibrosis is not currently available. OBJECTIVES: To assess the in vivo efficacy of a method to adjust the dose of enzymatic supplement in CF extrapolated from previous in vitro digestion studies (theoretical optimal dose, TOD). Secondly, to assess how individual patient characteristics influence the expected coefficient of fat absorption (CFA) and thus to identify an individual correction factor to improve TOD. METHODS: A prospective interventional study in 43 paediatric patients with CF from 5 European centres. They followed a 24h fixed diet with the theoretical optimal dose for each meal. Faecal collection was carried out between colorimetric markers in order to include all the faeces corresponding to the fixed diet. Beta regression models were applied to assess the associations of individual patient characteristics with the CFA. RESULTS: Median CFA was 90% (84, 94% 1st, 3rd Q.) with no significant differences among centres. Intestinal transit time was positively associated with CFA (p = 0.007), but no statistical associations were found with and age, gender, phenotype or BMI. Regression model showed no improvement of the in vitro predicted theoretical optimal dose when taking individual patient characteristics into account. CONCLUSION: Strict adherence to the theoretical optimal dose of enzymatic supplement for a prescribed meal, led to median CFA levels at the clinical target of 90% with a low variability between patients. The proposed method can be considered as a first approach for an evidence-based method in PERT dosing based on food characteristics. Results have to be confirmed in free dietary settings.

Detection and quantification of gluten immunogenic peptides in feces of infants and their relationship with diet

Background: there are no effective methods to easily control the correct adherence to a gluten-free diet (GFD) in celiac disease (CD) patients. Aim: to assess the sensitivity and specificity of a rapid immunochromatographic (IC) test that detects gluten immunogenic peptides (GIP) in feces, compared to an enzyme-linked immunosorbent assay (ELISA) method. Methods: fecal samples from healthy infants were analyzed by a rapid IC test and ELISA, both methods are based on the anti-gliadin 33-mer monoclonal antibody. Group 1 included infants aged from 6 to 24 months, with an unrestricted consumption of gluten containing cereals. Group 2 (negative controls) was comprised of infants aged from 0 to 6 months, either breastfed or formula fed who had never ingested gluten. Results: in group 1 (n = 34), all infants had positive values by ELISA, the mean was 13.13 μgGIP/g (range 0.56-46.79). The IC test was negative in 5/20 cases and there was a significant correlation (p=0.006) between the mean daily gluten intake and GIP in feces. In group 2 (n = 20), all the samples were negative by both methods. Moreover, the Kappa Fleiss concordance index (Kappa = 0.79 CI95% [0.616, 0.965]) indicated a moderate concordance between both methods. Conclusions: according to our results, both methods are highly specific. However, the ELISA test had a higher sensitivity. Although we found a significant correlation between the amount of gluten consumed and GIP recovery in feces, further studies are needed to clarify the impact of individual confounding factors in GIP recovery

Differences in the macronutrient and dietary fibre profile of gluten-free products as compared to their gluten-containing counterparts.

BACKGROUND/OBJECTIVES: Gluten-free diet is the lifelong therapy for patients with coeliac disease. A wide range of gluten-free products (GFP) is available, which mimics the characteristics of their gluten-containing counterparts (GCC). The aim of this study was to compare the macronutrient and dietary fibre composition of GFP and GCC currently available in Spain. SUBJECTS/METHODS: A cross-sectional study analysing the nutritional differences between 621 GFP and 600 GCC based on labelling information was conducted. Food items were categorized in one of 14 food groups. The first six ingredients were noted for each food item. A linear regression model was used to explain differences in nutritional composition between GFP and GCC and three independent models were created for bread, pasta and biscuits. RESULTS: Results showed that GCC had higher protein content than GFP, especially in flour, bread, pasta and pizza. Bread had higher total and saturated fat contents in the GFP in which palm oil was the main fat used. Flours and starchy ingredients used in GFP formulation were mainly rice and corn flours and corn starch, and palm oil was the most commonly used fat. CONCLUSIONS: In conclusion, GFP cannot currently be considered as equivalent substitutes for their GCC. The reformulation of the GFP with more healthy ingredients and ingredients is encouraged, using a healthy oil, pseudocereals and whole flour.

Diez años de seguimiento de la cohorte española del estudio Europeo PreventCD: lecciones aprendidas / Ten years of follow-up of the Spanish cohort of the European PreventCD study: the lessons learned

Objetivo: evaluar la influencia del consumo de gluten en el desarrollo de enfermedad celiaca y describir la historia natural de la misma, en una cohorte española de riesgo genético participante en el estudio Europeo PreventCD. Métodos: estudio prospectivo multicéntrico doble ciego, incluyendo 225 niños, controlados desde el nacimiento, en tres centros de Madrid, Reus y Valencia, todos HLA-DQ2/HLA-DQ8 positivos y con un familiar de primer grado con enfermedad celiaca. Entre cuatro y diez meses, la ingesta de gluten estaba pautada por protocolo. Entre los 11-36 meses, la ingesta fue libre, siendo cuantificada prospectivamente mediante registros dietéticos. Se realizaron visitas clínicas y análisis de anticuerpos específicos de enfermedad celiaca periódicamente. Conclusiones: ni la cantidad de gluten consumida entre los 11 y los 36 meses ni la duración de la lactancia son factores de riesgo de desarrollo de EC en la población española, siendo el genotipo HLA y el sexo los factores más relevantes asociados a la misma. En este grupo de riesgo, la mayoría de casos debutaron antes de los dos años, encontrándose a esta temprana edad pacientes con escasa expresividad clínica

Aim: to evaluate the influence of gluten consumption on celiac disease development and to describe its natural history in the Spanish cohort of the European PreventCD study. Methods: prospective multi-center double blind study of 225 children that were followed up from birth. All cases were HLA-DQ2/HLA-DQ8 positive with a 1st degree relative with celiac disease and were followed up in three centers from Madrid, Reus and Valencia. Gluten intake was determined between four and ten months according to the protocol. Gluten intake was ad libitum between eleven and 36 months and was prospectively quantified by means of dietary records. Clinical visits and specific antibody analysis for celiac disease were performed periodically. Results: twenty-six cases were diagnosed, all had a positive biopsy and serology; 21 had gastrointestinal symptoms and five were asymptomatic. In addition, 2,565 food records were analyzed and statistically significant differences (p < 0.001) were found with regard to gluten consumption among the three centers, although not between celiac and non-celiac children (p = 0.025). The HLA-DQ2.5/DQ2.5 and DQ2.5/DQ2.2 genotypes had a relative risk of 4.7 (95% CI: 0.80-27.55; p = 0.08), which was higher than for the rest of genotypes. Female gender also had a relative risk that was five times higher than that for males. Conclusions: the amount of gluten intake between 11 and 36 months or the duration of breast feeding were not risk factors for the development of CD in the Spanish population. The HLA genotype and gender were the most relevant associated factors. In this at-risk group, the disease presented before two years of age in the majority of the cases with a weak clinical expression

Anti-gliadin antibodies in breast milk from celiac mothers on a gluten-free diet.

PURPOSE: To analyze the presence of total IgA and anti-gliadin antibodies (AGA) in BM from CD mothers who follow a gluten-free diet (GFD) and from mothers on a normal gluten-containing diet (ND). METHODS: 218 samples of mature milk were obtained at different months of lactation (1-6) from 83 mothers (2 or more samples per mother) from Italy (Naples), The Netherlands (Leiden) and Spain (Madrid, Valencia and Reus): 42 CD mothers on GFD for more than 2 years and 41 non-CD mothers on a ND. Whey samples were analyzed for AGA-IgA by an indirect homemade ELISA and for total IgA (g/L) by a commercial ELISA kit. RESULTS: AGA-IgA was detected in BM, both in mothers on a GFD and mothers on a ND. AGA-IgA levels in both groups of mothers, CD and non-CD, show the same trend towards decreasing slightly along the months of lactation (p = 0.91). A different trend is observed for total IgA levels, decreasing markedly in CD mothers from the first month of lactation onwards but remaining stable in non-CD mothers (p = 0.048). A statistically significant association was found between the means of total IgA and AGA-IgA (p < 0.001). CONCLUSION: AGA-IgA is present in BM from mothers on a ND as well as in BM from mothers who had been on a GFD for years. This reflects the existence of a long-lasting immunological memory independent of the mother's diet. If the presence of these antibodies has any role in promoting the acquisition of gluten tolerance in the infant, our study shows that children of CD mothers would be on equal conditions as children of non-CD mothers.

Innovative approach for self-management and social welfare of children with cystic fibrosis in Europe: development, validation and implementation of an mHealth tool (MyCyFAPP).

INTRODUCTION: For the optimal management of children with cystic fibrosis, there are currently no efficient tools for the precise adjustment of pancreatic enzyme replacement therapy, either for advice on appropriate dietary intake or for achieving an optimal nutrition status. Therefore, we aim to develop a mobile application that ensures a successful nutritional therapy in children with cystic fibrosis. METHODS AND ANALYSIS: A multidisciplinary team of 12 partners coordinate their efforts in 9 work packages that cover the entire so-called 'from laboratory to market' approach by means of an original and innovative co-design process. A cohort of 200 patients with cystic fibrosis aged 1-17 years are enrolled. We will develop an innovative, clinically tested mobile health application for patients and health professionals involved in cystic fibrosis management. The mobile application integrates the research knowledge and innovative tools for maximising self-management with the aim of leading to a better nutritional status, quality of life and disease prognosis. Bringing together different and complementary areas of knowledge is fundamental for tackling complex challenges in disease treatment, such as optimal nutrition and pancreatic enzyme replacement therapy in cystic fibrosis. Patients are expected to benefit the most from the outcomes of this innovative project. ETHICS AND DISSEMINATION: The project is approved by the Ethics Committee of the coordinating organisation, Hospital Universitari La Fe (Ref: 2014/0484). Scientific findings will be disseminated via journals and conferences addressed to clinicians, food scientists, information and communications technology experts and patients. The specific dissemination working group within the project will address the wide audience communication through the website (http://www.mycyfapp.eu), the social networks and the newsletter.

The role of gluten consumption at an early age in celiac disease development: a further analysis of the prospective PreventCD cohort study.

Background: We previously found that the introduction of small quantities of gluten at 4-6 mo of age did not reduce the risk of celiac disease (CD) in a group of high-risk children. However, the consumption of high amounts of gluten early in life has been suggested to increase CD risk.Objective: The aim of this study was to evaluate this hypothesis by using data from the previous study of the PreventCD trial (www.preventcd.com).Design: Gluten intake was prospectively quantified by using specific food records between 11 and 36 mo of age in 715 children positive for the human leukocyte antigen (HLA)-DQ2 and/or HLA-DQ8 from 5 European countries. According to the PreventCD protocol, infants received 100 mg immunologically active gluten/d or placebo from 4 to 6 mo of age, with a stepwise and fixed gluten increase until age 10 mo and unrestricted intake thereafter. The primary outcome of the present study was the impact of the amount of gluten consumed from age 10 mo onward on CD development.Results: Mean daily gluten intakes from 10 mo onward were significantly different between countries for children at all ages (P < 0.001) but not between children who developed CD and those who did not within the same country (P > 0.05). The variables country, sex, intervention group, and gluten consumption pattern did not show significant associations with CD development risk (HRs not significant). In addition, the interaction between HLA risk group and gluten consumption pattern showed no significant risk on CD development, except for the DQ2.2/DQ7 haplotype (HR: 5.81; 95% CI: 1.18, 28.74; P = 0.031).Conclusions: Gluten consumption patterns as well as the amount of gluten consumed at 11-36 mo of age do not influence CD development for most related HLA genotypes in children with a genetic risk. This study reports the gluten consumption pattern in children at risk of CD from different European countries. This trial was registered at www.controlled-trials.com as ISRCTN74582487.
