Abstract
Coeliac disease is a systemic disorder characterized by immune-mediated enteropathy, which is caused by gluten ingestion in genetically susceptible individuals. The clinical presentation of coeliac disease is highly variable and ranges from malabsorption through solely extra-intestinal manifestations to asymptomatic. As a result, the majority of patients with coeliac disease remain undiagnosed, misdiagnosed or experience a substantial delay in diagnosis. Coeliac disease is diagnosed by a combination of serological findings of disease-related antibodies and histological evidence of villous abnormalities in duodenal biopsy samples. However, variability in histological grading and in the diagnostic performance of some commercially available serological tests remains unacceptably high and confirmatory assays are not readily available in many parts of the world. Currently, the only effective treatment for coeliac disease is a lifelong, strict, gluten-free diet. However, many barriers impede patients' adherence to this diet, including lack of widespread availability, high cost, cross-contamination and its overall restrictive nature. Routine follow-up is necessary to ensure adherence to a gluten-free diet but considerable variation is evident in follow-up protocols and the optimal disease management strategy is not clear. However, these challenges in the diagnosis and management of coeliac disease suggest opportunities for future research.

Abstract
Humankind has existed for 2·5 million years but only in the past 10 000 years have we been exposed to wheat. Therefore, it could be considered that wheat (gluten) is a novel introduction to humankind's diet! Prior to 1939, the rationing system had already been devised. This led to an imperative to try to increase agricultural production. Thus, it was agreed in 1941 that there was a need to establish a Nutrition Society. The very roots of the Society were geared towards necessarily increasing the production of wheat. This goal was achieved and by the end of the 20th century, global wheat output had expanded by 5-fold. Perhaps, as a result, the epidemiology of coeliac disease (CD) or gluten sensitive enteropathy has changed. CD now affects 1 % or more of all adults. Despite this, delays in diagnosis are common, for every adult patient diagnosed approximately three–four cases are undetected. This review explores humankind's relationship with gluten, wheat chemistry, the rising prevalence of modern CD and the new entity of non-coeliac gluten or wheat sensitivity. The nutritional interventions of a low fermentable oligo-, di- and mono-saccharides and polyols diet and gluten-free diet (GFD) for irritable bowel syndrome and the evidence to support this approach (including our own published work) are also reviewed. There appears to be a rising interest in the GFD as a ‘lifestyler’, ‘free from’ or ‘clean eater’ choice, causing concern. Restrictive diets may lead to potential nutritional implications, with long-term effects requiring further exploration.

Abstract
Mankind has existed for 2·5 million years but only in the last 10 000 years have we been exposed to wheat. Wheat was first cultivated in the Fertile Crescent (South Western Asia) with a farming expansion that lasted from about 9000BC to 4000BC. Thus it could be considered that wheat (and gluten) is a novel introduction to man's diet! Prior to 1939 the rationing system had already been devised. This led to an imperative to try to increase agricultural production. Thus it was agreed in 1941 that there was a need to establish a Nutrition Society. The very roots of the society were geared towards necessarily increasing the production of wheat. This goal was achieved and by the end of the 20th century, global wheat output had expanded 5-fold. Perhaps as a result the epidemiology of coeliac disease (CD) or gluten sensitive enteropathy has changed. CD is a state of heightened immunological responsiveness to ingested gluten in genetically susceptible individuals. CD now affects 1 % or more of all adults, for which the treatment is a strict lifelong gluten-free diet. However, there is a growing body of evidence to show that a far greater proportion of individuals without coeliac disease are taking a gluten-free diet of their own volition. This clinical entity has been termed non-coeliac gluten sensitivity (NCGS), although the condition is fraught with complexities due to overlap with other gluten-based constituents that can also trigger similar clinical symptoms. This review will explore the relationship between gluten, the rising prevalence of modern coeliac disease, and the new entity of NCGS along with its associated uncertainties.

Abstract
UNLABELLED Coeliac disease is an important clinical disorder affecting the human gastrointestinal tract leading to multiple signs and symptoms in different body organs. This disease was the subject of a cross sectional descriptive-analytic study conducted in the Gaza Strip during 2010. Objectives were oriented to identify and verify several variables and attributes affecting the prognosis of coeliac disease in the patients. Ninety five children out of 113 patients were arranged into two groups according to age from 2 to 11 years and from 12 to 18 years old. Results showed the poor interest of health professionals regarding coeliac disease in the Gaza Strip. The mean age of study population was 5.47 years for males and 8.93 years for females. The lifestyle of coeliac patients was directly proportional with better nutritional indictors. Poor recognition of the emblem illustrating gluten in foods implicates effective health awareness or promotion. The more knowledgeable patients or mothers (P = 0.036) were the more compliant. The compliance to giving gluten free foods outside home was statistically significant (P = 0.037). Similarly, cautious approach when buying foods or detergents (P = 0.011). According to BMI 74.4%, 23.4% and 3.2% of all patients were normal, underweight and overweight respectively. Albumin blood level was normal in 32.6% and low in 67.4%. Meanwhile, blood calcium level was normal in 76.8%, low in 21.1% and high in 2.1% of all patients. CONCLUSION The study showed that recreation and social activities for coeliac patients are substantially missing in the Gaza Strip. Moreover, the study proved that AEI is a reliable centre for care of coeliac disease patients and conducting relevant studies. RECOMMENDATION There is a need for thorough and continuous community and institutional mobilization regarding coeliac disease in the Gaza Strip and in Palestine.

Abstract
OBJETIVOS: avaliar a positividade sorológica para doença celíaca em um grupo de adolescentes e adultos jovens da cidade do Recife, Nordeste do Brasil. MÉTODOS: a amostra foi composta por estudantes matriculados nos cursos de graduação do Centro de Ciências da Saúde da Universidade Federal de Pernambuco. Os estudantes foram submetidos à coleta de sangue para pesquisa sorológica do anticorpo antitransglutaminase tecidual humana e responderam a questionário sobre sintomas e condições mórbidas associadas à doença celíaca. O anticorpo antitrans-glutaminase foi pesquisado por técnica de Elisa, considerando-se positivos valores acima de 10 U/mL, conforme estabelecido pelo fabricante. Nos pacientes que tiveram sorologia positiva para o anticorpo antitransglutaminase realizou-se a sorologia para o anticorpo antiendomíseo, por imunofluorescência indireta, utilizando kit comercialmente disponível. RESULTADOS: seiscentos e oitenta e três universitários participaram da pesquisa. Os estudantes tinham entre 18 e 30 anos e mediana de idade de 21 anos. O anticorpo antitransglutaminase foi positivo em 12/683, soroprevalência de 1,76% (IC95%: 0,95-3,13%). O anticorpo antiendomíseo foi realizado em 11 amostras e reagente em quatro. Oito estudantes com sorologia positiva tinham sintomas e/ou condições mórbidas associadas à doença celíaca. CONCLUSÕES: a elevada presença de anticorpos anti-transglutaminase encontrada neste estudo é semelhante a da Europa e Estados Unidos da América, sugere a possibilidade da triagem sorológica mesmo em populações consideradas de baixo risco.

Frequency distribution of HLA DQ2 and DQ8 in celiac patients and first-degree relatives in Recife, northeastern Brazil. Clinics (Sao Paulo) 2011; 66:227-31. [PMID: 21484038 PMCID: PMC3059855 DOI: 10.1590/s1807-59322011000200008] [Citation(s) in RCA: 18] [Impact Index Per Article: 1.4] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/10/2010] [Accepted: 11/03/2010] [Indexed: 02/06/2023] Open
Abstract
AIMS The aim of this study was to evaluate the frequencies of the HLA genotypes DQ2 and DQ8 and the alleles A1*05, A1*0201, B1*0201 and B1*0302 in individuals with celiac disease in Recife, northeastern Brazil. METHODS HLA DQ2 and DQ8 genotyping was performed for 73 individuals with celiac disease and 126 first-degree relatives with negative transglutaminase serology. The alleles DQA1*05, DQA1*0201, DQB1*02 and DQB1*0302 were identified by sequencing using specific primers and the EU-DQ kit from the Eurospital Laboratory, Trieste, Italy and double-checked by the All Set SPP kit (Dynal). RESULTS Among the 73 cases, 50 (68.5%) had the genotype DQ2, 13 (17.8%) had DQ8, 5 (6.8%) had DQ2 and DQ8, and 5 did not have any of these genotypes. Among the 5 negative individuals, four had the B1*02 allele and one did not have any of the alleles studied. B1*02 was the most frequent allele in both groups (94% in the patients and 89% in the control relatives). CONCLUSIONS In this study, celiac disease was associated with the genotypes DQ2 and DQ8. DQ2 predominated, but the distribution of the frequencies was different from what has been found in European populations and was closer to what has been found in the Americas. The high frequencies of the HLA genotypes DQ2 and DQ8 that were found in first-degree relatives would make it difficult to use these HLA genotypes for routine diagnosis of celiac disease in this group.

Abstract
Aim: To explore how 12-year-old Swedish children experienced being involved in a coeliac disease (CD) screening. Methods: A qualitative approach was used to analyse short narratives written by children who had taken part in a school-based CD screening. Narratives were written after blood sampling, but prior to learning of the test results. Through an oscillation between the texts, codes, subcategories and four categories, a theme was generated describing the children’s experience. Results: The theme ‘‘A Journey towards Confidence’’ captures the overall experience of the screening. It illustrates that, although some children faced fear or anxiety, overall they had or were provided tools allowing them to cope well and experience a journey towards confidence. The categories describe conditions that contributed to the experience. The first, being involved, reflects the importance of involvement in receiving information and deciding to participate. Being a ‘‘good citizen’’ refers to feeling a duty to help and a trust to be treated fairly. Being able to cope with the screening was influenced by the children’s ability to manage sensations and support received. The last category, being able to balance risk, illustrates that the children were able to balance the risks of screening when they had a realistic understanding of the disease and their vulnerability and had tamed their anxiety. Conclusions: This study increases the understanding of how 12-year-old Swedish children experienced participating in a CD screening and describes conditions important for a positive experience. We show that, although some children faced anxiety, they had, or were provided with, tools allowing them to cope well and gain confidence.

Abstract
AIM To determine if there is any regional celiac disease (CD) risk variation in the Swedish childhood population. METHODS Prospective nationwide Swedish incidence register of CD in children 0-15 years of age, with the present analysis covering the period from 1998 to 2003. ESPGHAN diagnostic criteria for CD were used. Regions were classified according to the Nomenclature of Territorial Units for Statistics. The incidence rate for each region, gender, age group and year of diagnosis was calculated. RESULTS A regional variation in CD risk was demonstrated. The childhood populations in 'West Sweden' and 'Småland and the islands', situated in the southern part of the country, had a significantly higher incidence rate compared to in 'North Middle Sweden' and 'Stockholm', situated in the central part. This regional variation was not explained by variations in risk by gender, age at diagnosis or year of diagnosis. CONCLUSION The Swedish regional variation in CD risk supports multifactorial disease aetiology. Continued efforts are warranted to define factors, besides gluten exposure, that modulate CD risk.
