Abstract
Punjabis are one of the largest ethnic groups in the world, with at least 124 million members. Their diet is based around wheat cereals and they are now recognised to be at risk of coeliac disease. Indeed, the incidence of coeliac disease amongst Punjabi migrants is three times that of other Europeans, suggesting that in excess of 3 million Punjabi people may be affected by the condition. This review considers the history of coeliac disease and its lack of ready diagnosis in the Punjabi community, including the adverse outcomes as a result. It considers the poor-quality information available to Punjabi patients and tentatively suggests methods of dealing with these issues.

Abstract
Celiac disease, once thought to be very uncommon in Asia, is now emerging in many Asian countries. Although the absolute number of patients with celiac disease at present is not very high, this number is expected to increase markedly over the next few years/decades owing to increasing awareness. It is now that the medical community across the Asia should define the extent of the problem and prepare to handle the impending epidemic of celiac disease in Asia.

Abstract
Coeliac disease (CD) is an immune-mediated disorder triggered by the ingestion of gluten in genetically susceptible individuals. However, only a small proportion of subjects harbouring CD-related genetic risk develop the disease. Among the environmental factors that may influence CD risk, pre- and perinatal factors, delivery methods, parental lifestyle, infant feeding practices, seasonality, dietary factors, drug use, childhood infections and variability in gut microbiota are those most widely studied regarding the risk to develop CD. Although for many of these external factors the exact mechanism of action is unknown, most of them are thought to act by disrupting the intestinal barrier, facilitating contact between potential antigens and the immune system effector cells. Management of CD is relatively easy in patients with a definite diagnosis and requires a strict, lifelong, gluten-free diet. Better knowledge of environmental exposures apart from gluten can facilitate understanding of the pathogenesis of the disorder and the wide heterogeneity of its clinical spectrum. The purpose of this review is to discuss current knowledge on environmental CD risk factors, as well as possible interaction between them, on the grounds of the reliable scientific evidence available. Key messages The risk of developing CD is influenced not only by gluten ingestion but also by a number of environmental factors including childhood infections and variability in gut microbiota, pre- and perinatal factors, infant feeding practices, delivery methods, parental lifestyle, seasonality, dietary factors and drug use, acting mainly by disrupting intestinal permeability. Better knowledge of exposure to these factors can facilitate their identification, and subsequent elimination, in the individual patient.

Abstract
BACKGROUND & AIMS Celiac disease is an increasingly recognized disorder in Caucasian populations of European origin. Little is known about its prevalence in non-Caucasians. Although it is thought to be a cause of iron-deficiency anemia, little is known about the extent to which celiac disease contributes to iron deficiency in Caucasians, and especially non-Caucasians. We analyzed samples collected from participants in the Hemochromatosis and Iron Overload Screening study to identify individuals with iron deficiency and to assess the frequency of celiac disease. METHODS We analyzed serum samples from white men (≥25 y) and women (≥50 y) who participated in the Hemochromatosis and Iron Overload Screening study; cases were defined as individuals with iron deficiency (serum ferritin level, ≤12 μg/L) and controls were those without (serum ferritin level, >100 μg/L in men and >50 μg/L in women). All samples also were analyzed for human recombinant tissue transglutaminase immunoglobulin A; positive results were confirmed by an assay for endomysial antibodies. Patients with positive results from both celiac disease tests were presumed to have untreated celiac disease, and those with a positive result from only 1 test were excluded from analysis. We analyzed HLA genotypes and frequencies of celiac disease between Caucasians and non-Caucasians with iron deficiency. RESULTS Celiac disease occurred in 14 of 567 cases (2.5%) and in only 1 of 1136 controls (0.1%; Fisher exact test, P = 1.92 × 10(-6)). Celiac disease was more common in Caucasian cases (14 of 363; 4%) than non-Caucasian cases (0 of 204; P = .003). Only 1 Caucasian control and no non-Caucasian controls had celiac disease. The odds of celiac disease in individuals with iron deficiency was 28-fold (95% confidence interval, 3.7-212.8) that of controls; 13 of 14 cases with celiac disease carried the DQ2.5 variant of the HLA genotype. CONCLUSIONS Celiac disease is associated with iron deficiency in Caucasians. Celiac disease is rare among non-Caucasians-even among individuals with features of celiac disease, such as iron deficiency. Celiac disease also is rare among individuals without iron deficiency. Men and postmenopausal women with iron deficiency should be tested for celiac disease.

Abstract
BACKGROUND AND OBJECTIVES Rickets is commonly seen as a sign of malabsorption like celiac disease if it is not treated appropriately with vitamin D and calcium supplements. The aim of this study was to examine the frequency of diagnosis of celiac disease among children with unexplained rickets in Saudi children at a tertiary hospital setting. DESIGN AND SETTING Retrospective review of records of patients referred over 10 years to a pediatric gastroenterology and hepatology unit. PATIENTS AND METHODS The study included all patients referred for evaluation of unexplained rickets and osteomalacia and screened for celiac disease. The diagnosis of rickets was made on the basis of history, physical examination, biochemical and radiological investigations. The diagnosis of celiac disease was made based on the ESPGHAN (European Society for Pediatric Gastroenterology, Hepatology, and Nutrition) criteria. RESULTS Twenty-six children with a mean (SD) age of 9.5 (4.6) years (5 males, range 1-15 years) were referred for evaluation of unexplained rickets and were screened for celiac disease. The diagnosis of celiac disease based on small bowel biopsy findings was confirmed in 10 (38.4%) patients with rickets. Serological markers for celiac disease including antiendomyseal antibodies and antitissue transglutaminase antibodies were positive in all ten children. CONCLUSION Rickets is not an uncommon presentation of celiac disease in Saudi children and pediatricians should consider celiac disease as an underlying cause for rickets.

Abstract
BACKGROUND Coeliac disease affects adult Asians from north India, Pakistan and Bangladesh in the UK but how commonly this occurs is unknown. An audit of coeliac disease was therefore conducted in a well-defined area in southern Derbyshire. METHODS All white and Asian patients with biopsy-confirmed coeliac disease diagnosed between 1958 and 2008 were identified. Population data from the Office of National Statistics allowed the calculation of prevalence. Presenting symptoms, adherence to a gluten-free diet and follow-up record were determined for Asians and compared with matched white patients. RESULTS Among 1305 coeliac patients diagnosed between 1958 and 2008, 82 were Asian. Coeliac disease occurred significantly more frequently in Asian than white individuals and this could be attributed to the significantly higher prevalence in women 16 years and older and under 60 years of age. No Asian man over the age of 65 years was diagnosed with coeliac disease. Asians are more likely to present with anaemia and less likely to present with diarrhoea than white individuals. Asians are less likely to adhere to a strict gluten-free diet than white patients. CONCLUSIONS This baseline audit indicates that increased efforts should be directed towards diagnosing coeliac disease in Asian men over the age of 65 years, in whom at present it is unrepresented. Strategies also need to be developed to help more Asian patients adhere strictly to the gluten-free diet.

Abstract
OBJECTIVES The burden of celiac disease (CD) is increasingly recognized as a global problem. However, whether this situation depends on genetics or environmental factors is uncertain. The authors examined these aspects in Sweden, a country in which the risk of CD is generally considered to be high. If environmental factors are relevant, CD risk in second-generation immigrant children should be related to maternal length of stay in Sweden before delivery. MATERIAL AND METHODS Linking the Swedish Medical Birth Registry to other national registries, the authors investigated all singleton children (n = 792,401) born in Sweden between 1987 and 1993. They studied the risk of CD in children before age 6 as a function of the mother's geographical region of birth and length of stay in Sweden before delivery using Cox regression models. RESULTS In children whose mothers immigrated to Sweden from a country outside of Europe, a maternal length of stay in Sweden of more than 5 years increased the hazard ratio (HR) of CD (1.73, 95% confidence interval (CI) 1.06-2.81). The authors observed a similar result among children born to mothers from a Nordic country outside of Sweden (HR 1.57, 95% CI 0.89-2.75), but a non-conclusive protective effect was observed in second-generation immigrant children from a non-Nordic European country (HR 0.65, 95% CI 0.39-1.09). CONCLUSIONS The risk of CD among second-generation immigrants seems to be conditioned by maternal length of stay in Sweden before delivery, suggesting that environmental factors contribute to the variation in CD risk observed across populations.

Abstract
Panjabi is spoken by 1.3 million people in the UK. It is the second most common language used in the country and is the first choice of 75% of Panjabis. It is becoming more common. For many patients it forms part of the barrier which limits access to gastrointestinal services. The provision of appropriate support services is woeful and yet seldom leads to formal complaints. This review considers the impact of gastrointestinal disorders on the Panjabi community and assesses some of the interventions that could be developed to ensure equity of care.

Abstract
BACKGROUND AND AIMS The incidence of celiac disease (CD) shows large, worldwide variation. However, whether its causes are environmental (gluten-containing diet) or genetic (specific haplotype) have not been established. The aim of the present study is to examine the incidence of CD among second-generation immigrants and adoptees from abroad to disentangle genetic/ethnic versus environmental influences (assuming that immigrants have similar gluten exposures to native Swedes, and thus differ from them only in terms of their genetic background). METHODS Second-generation immigrants and adoptees from abroad were identified in the MigMed 2 Database and were followed until diagnosis of CD, death, or the end of study. Standardized incidence ratios (SIRs) were calculated among these immigrants with native Swedes as the reference group. RESULTS A total of 1,050,569 children were defined as second-generation immigrants and the overall SIR of CD (SIR = 0.89, 95% confidence interval 0.84-0.94) was significantly lower than that of native Swedes. The incidence of CD among children with parents from Western, Eastern, and Northern European countries was similar to that in native Swedes, but was lower for those with parents from low-prevalence countries, especially Eastern and Southeast Asian countries. A total of 51,557 children born in foreign countries were adopted by Swedes. Adoptees from Eastern Asia had a significantly decreased SIR of CD. CONCLUSIONS The decreased incidence of CD in second-generation immigrants and some groups of adoptees from abroad strongly suggests that ethnic genetic heterogeneity may contribute to the worldwide variation in CD incidence.

Abstract
BACKGROUND AND AIM While celiac disease is estimated to affect about 1% of the world's population, it is thought to be uncommon not only in India but in Asia also. There is a lack of studies on the prevalence of celiac disease from Asian nations. The aim of the present study was to estimate the prevalence of celiac disease in the community. METHODS In a cross sectional study, we estimated the prevalence of celiac disease in urban and rural populations in the National Capital Region, Delhi, India. A structured questionnaire was administered, by door-to-door visits, to all participants to collect socio-demographic data and to screen for features of celiac disease, namely chronic or recurrent diarrhea and, anemia. In children, additional features, namely short stature (linear height below 5th percentile for age) and failure to thrive/gain weight were also used. All respondents who were screen positive (any one of above) and 10% of screen negative individuals were called for serological testing, which is anti-tissue transglutaminase antibody. All serologically positive respondents were invited to undergo further evaluation including endoscopic biopsy. Celiac disease was diagnosed on the basis of a positive serology, the presence of villous atrophy and/or response to gluten free diet. RESULT Among 12,573 contacted, 10,488 (83.4%) (50.6% male) agreed to participate. Based on screening, 5622 (53.6%) participants were screen positive. Of all those screen positive, 2167 (38.5%) agreed for serological testing; additionally 712 (14%) negatives were also tested. The overall sero-prevalence of celiac disease was 1.44% (95% confidence interval [CI] 1.22 1.69) and the overall prevalence of celiac disease was 1.04% (95% CI 0.85 1.25). CONCLUSION The prevalence of celiac disease in this north Indian community is 1 in 96. Celiac disease is more common than is recognized in India.

Abstract
In the past, celiac disease was believed to be a chronic enteropathy, almost exclusively affecting people of European origin. The availability of new, simple, very sensitive and specific serological tests (anti-gliadin, anti-endomysium and anti-transglutaminase antibody assays) have shown that celiac disease is common not only in Europe and in people of European ancestry but also in the developing countries where the major staple diet is wheat (Southern Asia, the Middle East, North West and East Africa, South America), both in the general population and in the groups at risk. Gluten intolerance thus appears to be a widespread public health problem and an increased level of awareness and clinical suspicion are needed in the New World where physicians must learn to recognize the variable clinical presentations (classical, atypical and silent forms) of celiac disease. In the developing countries, both serological screening in the general population and serological testing in groups at risk are necessary for an early identification of celiac patients. The gluten-free diet poses a challenging public health problem in the developing countries, especially since commercial gluten-free products are not available.

Abstract
Celiac disease is an immune mediated enteropathy initiated by ingestion of gluten, in genetically susceptible individuals. With changing epidemiology, celiac disease initially thought to affect only Europeans, has been increasingly reported from other parts of the world including India. However, its true prevalence in India is still not known, as the diagnosis is being missed. The gold standards for diagnosis have been characteristic small intestinal mucosal changes on gluten and a full clinical remission on its removal from the diet. Presence of serological antibodies, which disappear on gluten free diet further confirms the diagnosis. The understanding of the histopathology of celiac disease has changed over the years. The small bowel mucosal lesion of celiac disease is an evolutionary process with normal mucosal architecture and an increase in intraepithelial lymphocytes at one end of the spectrum and classical flat mucosa at the other. In the Indian subcontinent celiac disease has a heterogeneous histological presentation and the diagnosis may be missed if it is based only on severe mucosal changes or the serology is not considered when moderate or mild mucosal changes are present. The last two decades have shown that antiendomysical (Anti EMA) and anti tissue transglutaminase antibodies (anti-tTGA) have a sensitivity and specificity of more than 95% to diagnose celiac disease. Anti EMA tests being operator dependent are more liable to errors and anti- tTGA may be preferred for large scale screening. However, the different source of tTGA antigen, varied techniques of production and the use of arbitrary units by different commercial kits can influence the diagnostic accuracy of the anti-tTGA assay. There is a strong genetic association of celiac disease with HLA-DQ2 or DQ8. The presence of HLA-DQ2 hetrodimer in more than 97% of a group of North Indian patients with celiac disease indicates that this population has a similar genetic risk for the disease. HLA DQ2 typing can be used for ruling out celiac disease where the diagnosis is equivocal as it has a negative predictive value of greater than 95%. Given the protean clinical manifestation and the heterogeneous histology a standard algorithm for diagnosis of celiac disease is important.

Abstract
BACKGROUND There are no available data concerning the incidence and the clinical pattern of coeliac disease in immigrant children coming to Italy from developing countries. AIMS To evaluate the epidemiological and clinical features of coeliac immigrant children coming to Italy. PATIENTS AND METHODS Hospital records of 1917 children diagnosed in 22 Italian Centres from 1999 to 2001 as having coeliac disease were retrospectively reviewed, comparing immigrant patients versus Italian ones. RESULTS 36/1917 (1.9%) coeliac children were immigrant. This prevalence was similar to that of the immigrant children among the whole paediatric population living in Italy. Prevalence was influenced by geographical factors, being higher in Northern Italy (1.7%) and in Central Italy (2.5%) than in Southern-Insular Italy (1.5%), as consequence of a higher proportion of immigrants in these regions. The native areas of the immigrant children were East Europe (15/36), Northern Africa (14/36), Southern Asia (4/36), West Africa (1/36), East Africa (1/36) and the Middle East (1/36). The clinical spectrum and dietary habits in immigrant patients were similar to those of the Italian children. CONCLUSIONS Coeliac disease among the immigrant children coming from developing countries is an emerging problem, and physicians need to be fully aware of it. An important risk factor for coeliac disease in immigrant children appears to be sharing of the same dietary habits with the Italian population. The finding of coeliac disease in children coming from many countries worldwide suggests that coeliac disease is a global public health problem.

Abstract
In the last years our knowledge on epidemiology of celiac disease has increased: there is a wide spectrum of its clinical presentation (classical, atypical, silent and latent forms of celiac disease), and of its pathological mucosal intestinal features, which range from early and mild pictures to severe villous atrophy (Marsh stages). In addition, a strong genetic component, associated with the susceptibility to the disease (HLA and non HLA genes), has been found. This knowledge, together with the availability of new high sensitive and specific serological tests (antigliadin, antiendomysium and antitransglutaminase antibodies), has led us to the realization that celiac disease is the most common food intolerance in the world, involving genetically predisposed individuals consuming gluten-containing cereals in their diet. So, today it is well known that celiac disease is a common disorder not only in Europe but also in populations of European ancestry (North and South Americas, Australia), in North Africa, in the Middle East and in South Asia, where until a few years ago it was historically considered extremely rare. Therefore, celiac disease is spread worldwide as in a common "Global Village", and greater levels of awareness and attention on gluten intolerance are needed, both in the Old and in the New World.

Abstract
BACKGROUND In a developing country, many conditions other then celiac disease (CD) can give rise to villous atrophy. We therefore assessed the role of immunoglobulin A (IgA)-antigliadin antibody (AGA) in addition to the ESPGHAN criteria in the diagnosis of CD in 104 Indian children. METHODS Consecutive children with suspected CD were evaluated over 3 years with an intention to diagnose CD. Complete hemogram, d-xylose absorption test, endoscopic duodenal biopsy, and IgA-AGA titers were performed in all. CD was diagnosed on the basis of modified ESPGHAN criteria irrespective of IgA-AGA positivity (>5 U/mL), and those diagnosed were put on gluten-free diet and were monitored regularly. Children with suspected CD who had a normal duodenal biopsy result were taken as controls. RESULTS The mean age of 50 children with CD was 6.3 +/- 2.6 years, with a male to female ratio of 3:2. The mean duration of symptoms was 3.4 +/- 2.2 years. Predominant symptoms were pallor in 96%, failure to thrive in 92%, and diarrhea in 80%. On follow-up (19.6 +/- 8 months), symptoms subsided within 16 +/- 9.8 days, and patients showed significant weight gain (mean weight at diagnoses and at last follow-up visit were 66% and 86% of expected, respectively; P < 0.001) and height gain (mean height at diagnoses and at last follow-up visit were 88% and 94% of expected, respectively; P = nonsignificant). The control group comprised 47 children with a mean age of 6.9 +/- 3 years. On comparing CD with controls, diarrhea, anemia, low weight, and stunting were significantly (P < 0.001) more frequent in patients with CD. Sensitivity and specificity of AGA at a cutoff value of 5 U/mL were 94% and 91.5% and at 10 U/mL 88% and 100%, respectively. Follow-up AGA test was performed in 42 of 47 positive cases. All showed significant decrease in AGA titer, and 29 (70%) had a negative test result. CONCLUSIONS Indian children with CD are true cases of CD. They present late, diarrhea is absent in 20% of cases, and AGA test results show 88% of children without false-positive results at a cutoff value of 10 U/mL. However, AGA test with 94% sensitivity at a cutoff value of 5 U/mL can be used as screening test to select suspected cases for further workup.

Abstract
Aside from infectious intestinal diseases with known etiology, there is a group of gastrointestinal disorders mainly affecting the small intestine of individuals predominantly living in and less often visiting or returning from the Third World, usually the tropics, and ranging from asymptomatic structural and/or functional abnormalities of the gastrointestinal mucosa (subclinical enteropathy, SE) to a fully symptomatic condition highlighted by malabsorption of nutrients with associated nutritional deficiencies responsive to folate and broad spectrum antibiotic treatment (tropical sprue, TS). Mounting evidence supports an infectious cause in many instances. The exact nature of the infection, whether initiated and/or perpetuated by enterotoxigenic coliform bacteria, virus(es) or a combination of these, is not clear. Further studies, including those using molecular techniques, are needed in order to clarify various aspects of these widely prevalent disorders.

Abstract
A systematic study of celiac disease in a defined population of Arab children has not been previously reported. We therefore performed a prospective study to determine the incidence and clinical presentation of celiac disease in Jordanian children. A total of 34 (12 boys and 22 girls) cases were diagnosed over a period of 36 months. Nine cases were clustered in three families. The incidence was calculated to be 1:2,800 live births. The mean age at presentation was 4.6 years (range 0.3-13), but it was 8.4 years at the time of diagnosis. Diarrhea was the main initial symptom in 15 (44%) patients. Other signs and symptoms included recurrent abdominal pain in five patients (14%), short stature in four (12%), abdominal distension in three (9%), constipation in three (9%), pallor and recurrent mouth ulcers in two patients each. At the time of diagnosis, 24 (71%) had hypochromic microcytic anemia, and nine (26%) had rickets. The relatively high incidence of celiac disease may be related to the large wheat consumption in this population (135 kg/head/year), and the late onset could be related to the widespread prevalence of prolonged breast-feeding in Jordan (12 months) and late introduction of cereals (6.2 months) in children with late presentation. The delay in diagnosis might be due to the presence of other diseases clinically resembling celiac disease in our community.

Abstract
Coeliac disease usually presents in infancy or early childhood with diarrhoea, vomiting and interference with weight gain and growth. Withdrawal of dietary gluten is followed by resolution of the symptoms and signs and restoration of normal weight gain and growth; the characteristic subtotal villous atrophy of the jejunal mucosa also recovers. Later re-introduction of dietary gluten will lead to a return of the jejunal mucosal abnormality in the majority and to clinical relapse in many but not all. The severity and timing of both are variable and 5% of children initially considered on clinical, biopsy and gluten response evidence to have coeliac disease appear to develop permanent tolerance to gluten, although mucosal relapse may occur years after the re-introduction of dietary gluten in a minority, emphasizing the need for long-term follow-up. Although a diagnostic and subsequent follow-up jejunal biopsy are necessary to confirm the diagnosis, anti-gliadin IgA and IgG, anti-reticulum and anti-endomysium antibodies are now almost totally reliable in identifying children who have coeliac disease and are valuable in monitoring the adequacy of gluten withdrawal. Dietary compliance is frequently poor and regular supervision by a paediatric dietitian is needed; indeed, lifelong supervision to ensure gluten withdrawal is essential to reduce the chance of developing later gastrointestinal malignancy.

Abstract
Serum anti-gliadin antibody (AGA) titres were estimated by diffusion in a gel enzyme-linked immunosorbent assay in children with coeliac disease (n = 11), protracted diarrhoea of non-coeliac causes (n = 110), acute gastroenteritis (n = 20), protein energy malnutrition (n = 20), and asymptomatic, well-nourished children (n = 66). The mean IgG and IgA AGA titres were significantly higher (p less than 0.001) in children with coeliac disease than in any other groups. There was no significant difference (p greater than 0.01) in AGA titres in relation to age, nutritional status, or severity of villous injury. In patients with coeliac disease AGA titres showed a good correlation with disease activity. The specificity and sensitivity of the assay are discussed.

Abstract
Many Asian subjects were seen in London in the early 1970s with megaloblastic anaemia; in a majority of cases, this was dietary in origin. Pernicious anaemia occurs in Asians, but the incidence is probably lower than in Caucasians. Megaloblastic anaemia is now less common in this group, but a population survey in Punjabi females in the late 1970's showed anaemia in 32%, and one or more features of iron deficiency in 76%.

Abstract
Coeliac disease is generally considered to be a disease of Europe, North America, and Australasia. A series of well-authenticated cases from Cuba is presented. One of the factors responsible for the presence of this disease in Cuba may be the increase in wheat consumption in the last few years. It is likely that coeliac disease exists in other tropical countries.
