Type 1 diabetes and celiac disease: The effects of gluten free diet on metabolic control

Managing Children and Adolescents with Type 1 Diabetes and Coexisting Celiac Disease: Real-World Data from a Global Survey

INTRODUCTION

Celiac disease (CD) is among the diseases most commonly associated with type 1 diabetes (T1D). This study aimed to evaluate the worldwide practices and attitudes of physicians involved in pediatric diabetes care regarding diagnosing and managing CD in children with T1D.

METHODS

The 30-item survey was conducted between July and December 2023 aimed at targeting pediatricians with special interest in T1D and CD. It was shared by the JENIOUS - young investigators group of the International Society of Pediatric and Adolescent Diabetes (ISPAD) - and the YES - early career group of the European Society for Pediatric Endocrinology (ESPE).

RESULTS

Overall, 180 physicians (67.8% female) from 25 countries responded. Among respondents, 62.2% expected sustaining optimal glycemic control in children with T1D and CD (T1D + CD) to be more difficult than in children with T1D alone. Majority (81.1%) agreed that more specific guidelines are needed. The follow-up routine for patients with T1D + CD differed, and one-quarter of physicians scheduled more frequent follow-up checkups for these patients. Seventy percent agreed multidisciplinary outpatient clinics for their follow-up is needed. In the multivariate ordinal logistic regression model, a statistically significant predictor of a higher degree of practice according to ISPAD 2022 guidelines was a higher level of country income (OR = 3.34; p < 0.001).

CONCLUSIONS

These results showed variations in physicians' practices regarding managing CD in children with T1D, emphasizing the need for more specific guidelines and intensive education of physicians in managing this population, especially in lower-income countries. Our data also suggest the implementation of multidisciplinary outpatient clinics for their follow-up.

Vulnerability in Children with Celiac Disease: Findings from a Scoping Review

(1) Background: The scientific literature highlights that children diagnosed with celiac disease (CD) are at a heightened risk of experiencing physical, psychological, and social challenges, impacting their overall healthy childhood development. However, there remains a lack of a clear understanding regarding the factors that contribute to this vulnerability. The purpose of this study is to analyze and map the evidence on the sociopsychosomatic vulnerability of these children and identify gaps in this topic. (2) Methods: Following Joanna Briggs Institute's guidelines for scoping reviews, we executed a detailed search of key electronic databases and explored the grey literature to capture a broad spectrum of studies. Our focus was on identifying research that looked into the multiple dimensions of vulnerability-physical, psychological, and social-in children with CD. We included a diverse range of study designs as well as systematic reviews, ensuring a comprehensive analysis. The selection process was stringent, utilizing clearly defined inclusion and exclusion criteria. (3) Results: We identified 61 studies that met our inclusion criteria. The review highlighted significant adverse health outcomes in children with CD and elucidated various individual and environmental determinants that influenced these vulnerabilities. It also underscored the lack of assessment tools to evaluate the risk of health problems in this population. (4) Conclusions: The findings underscore a critical need for further research to deepen our understanding of the vulnerabilities associated with CD in children. Developing targeted assessment tools will be crucial in stratifying health risks and enhancing care strategies for this vulnerable population.

Effect of polyphenols from Ascophyllum nodosum seaweeds on the rheology and digestion of corn starch gels and gluten-free bread features

The main objective of this work is to study the effect of polyphenols, from the brown seaweed Ascophyllum nodosum, on the structure and digestion behaviour of gels at two corn starch concentrations (1.95 and 5.00% w/w) as well as the structure, color and texture features of crumbs from gluten-free breads. Adsorption isotherms of polyphenols on native and gelled starches were carried out and modelled by means of Langmuir and Henry models, respectively. The formation and characteristics of tested gels were rheologically monitored by means of heating ramp, time sweep at high temperature, cooling ramp and frequency sweep at 25 °C. Elastic modulus values decreased with the presence of polyphenols. Additionally, the polyphenols significantly decreased the digestion rate, measured by both chemical and rheological procedures, and the final concentration of digested starch. Finally, the presence of polyphenols in breads increased the hardness and chewiness values and decreased the cohesiveness and resilience values as well as the crumb hardening during storage.

Glycemic Response in Nonhuman Primates Fed Gluten-Free Rice Cakes Enriched with Soy, Pea, or Rice Protein and Its Correlation with Nutrient Composition

Celiac disease (CD) is a chronic disease caused by the consumption of gluten foods and is closely related to type 1 diabetes (T1D). Adherence to a gluten-free (GF) diet is the cornerstone of treating CD, and certain plant proteins added to GF foods affect blood glucose to varying degrees. The aim of this study was to analyze and compare the changes in glycemic index (GI) and incremental area under the postprandial glucose tolerance curve (IAUC) of various foods through consumption of GF foods supplemented with certain plant proteins in non-human primates. The test foods were GF rice cakes with 5%, 10%, and 15% added single plant proteins (rice protein, soy protein, and pea protein) mixed with rice flour, as well as 5%, 10%, and 15% gluten rice cakes, and rice flour alone, for a total of 13 food items, and 12 healthy cynomolgus monkeys were examined for their glucose levels in the blood after fasting and after eating each test food (50 g) for 15, 30, 45, 60, 90, and 120 min after fasting and eating each test food. Fingertip blood glucose levels were measured, and the nutrient content of each food, including protein, fat, starch, ash, and amino acids, was examined. All foods tested had a low GI (<50) when analyzed using one-way ANOVA and nonparametric tests. Postprandial IAUC was significantly lower (p < 0.05) for GF rice cakes with 15% pea protein (499.81 ± 34.46) compared to GF rice cakes with 5% pea protein (542.19 ± 38.78), 15% soy protein (572.94 ± 72.74), and 15% rice protein (530.50 ± 14.65), and GF rice cakes with 15% wheat bran protein (533.19 ± 34.89). A multiple regression analysis showed that glycine was negatively associated with IAUC in GF rice cakes with 5%, 10%, and 15% pea protein added (p = 0.0031 < 0.01). Fat was negatively correlated with IAUC in GF rice cakes supplemented with 5%, 10%, and 15% soy protein (p = 0.0024 < 0.01). In this study, GF rice cakes made with added pea protein were superior to other gluten and GF rice cakes and had a small effect on postprandial glucose.

The impact of gluten-free diet on growth, metabolic control and quality of life in youth with type 1 diabetes and celiac disease: A systematic review

AIMS

To evaluate the impact of gluten free diet (GFD) on growth, metabolic control and quality of life in children and adolescents with type 1 diabetes (T1D) and celiac disease (CD).

METHODS

A systematic search was performed including studies published in the last 15 years. PICOS framework was used in the selection process and evidence was assessed using the GRADE system.

RESULTS

Overall, studies comparing youth with T1D + CD on GFD to those with T1D only, showed no significant differences in growth parameters, HbA1c, number of episodes of hypoglycemia, total daily insulin doses. Studies assessing the effect of GFD introduction showed stable BMI and HbA1c. Only two studies assessed QoL of life, which was not different between T1D + CD vs T1D only youth, as well as pre- and post-CD diagnosis and introduction of GFD.

CONCLUSION

This systematic review, including only studies of moderate-high evidence quality level and reporting data on objectively assessed adherence to GFD, highlights that adherence to GFD in youth with T1D + CD leads to regular growth, stable BMI, without any negative effect on HbA1c and insulin requirements. Although assessed in few studies, lipid profile and QoL improved with the introduction of GFD.

Organ-specific autoimmune markers in adult patients with type 1 diabetes mellitus

AIM

We aimed to investigate the presence of thyroid, celiac disease (CD) and anti-parietal cell antibodies (APCA) in adult type 1 diabetes (T1DM) patients.

METHODS

Data of 287 T1DM patients >16 years old were reviewed retrospectively. Thyroid disease related, CD related antibodies and APCA were evaluated. Patients were divided into early onset (<30 years old) and late-onset (≥30 years old) TIDM, and ≤10 years, 11-20 years and >20 years according to disease duration.

RESULTS

There were 142 (49.5%) female and 145 (50.5%) male patients. The median age at diagnosis and disease duration were 21 (2-53) and 6.91 (0-50.8) years, respectively. Antibody positivity rates were anti-glutamic acid decarboxylase (anti-GAD) 72.8%, anti-insulin 9.1%, anti-islet cell 25.7%, antithyroid peroxidase (anti-TPO) 34.8%, anti-thyroglobulin 19.9%, anti-endomysial IgA (EMA-IgA) 7.6%, anti-gliadin IgA (AGA-IgA), 12.2%, AGA-IgG 13.0%, tissue transglutaminase IgA 7.1% and APCA 14.4%. One hundred twenty-eight (44.6%) patients had at least one non-diabetes autoantibody. Thyroid autoantibodies and dysfunction were significantly higher in women than men. Anti-TPO positivity was higher in the late-onset group (P = .044). Anti-GAD level was correlated with thyroid related antibody positivity in male patients with positive anti-GAD (r: .340, P: .006). The positivity of EMA-IgA and AGA-IgA was higher in patients with disease duration >20 years (P = .017 and .039, respectively).

CONCLUSION

Almost half of the adult T1DM patients were positive for at least one non-diabetic antibody. It is important to investigate thyroid autoimmunity in patients diagnosed with T1DM at any age, including advanced age. CD associated antibody positivity increases with disease duration, suggesting that they should be re-evaluated at clinical suspicion, even if prior tests were negative.

The Experience of a Gluten-free Diet in Children with Type 1 Diabetes and Celiac Disease

Objective

This study examined overall self-reported adherence to gluten-free diet (GFD) in children with type 1 diabetes and celiac disease (T1DCD) compared to children with celiac disease (CD). Secondary objectives included gaining insight into self-reported symptoms, barriers to adherence, and experience of a GFD between groups.

Methods

Children &lt;18 years old who had been seen at BC Children’s Hospital for T1DCD or CD were invited to participate in a web-based questionnaire and medical record review.

Results

A total of 26 children with T1DCD and 46 children with CD participated in the study. The groups’ demographics and symptoms of CD were similar; however, a greater proportion of those with T1DCD were asymptomatic at diagnosis (T1DCD 27%; CD 7%; P = 0.016). Overall adherence to a GFD was high in both groups (T1DCD 92%; CD 100%; P = 0.38) but those with T1DCD reported a significantly less positive effect on their health (P = 0.006) and a significantly greater negative effect on activities from a GFD (P = 0.03). Children with T1DCD reported more significant barriers to eating gluten-free at home and at restaurants, specifically with social pressure, cost and taste compared to those with CD only.

Conclusion

Children with T1DCD face specific barriers in adherence that are more impactful compared with children living with CD. These children are more often asymptomatic at diagnosis, and they go on to experience different impacts of a GFD spanning across home and social settings. Given the complexity of having a dual diagnosis, CD care should be tailored specifically to children living with T1DCD.

S2k guidelines (consensus statement) for diagnosis and therapy of dermatitis herpetiformis initiated by the European Academy of Dermatology and Venereology (EADV)

INTRODUCTION

Dermatitis herpetiformis (DH) is a chronic, pruritic, gluten-induced skin disorder characterized by subepidermal granular IgA deposition and a variable degree of enteropathy identical to that seen in coeliac disease. So far, there has been no European consensus about the management of DH.

METHODS

The guidelines were created by small subgroups of a guideline committee consisting of 26 specialists from various medical fields and one patients' representative. The members of the committee then discussed the guidelines and voted for the final version at two consensus meetings. The guidelines were developed under the support of the European Academy of Dermatology and Venereology (EADV) and in collaboration with the European Dermatology Forum (EDF).

RESULTS

The guidelines summarize evidence-based and expert-based recommendations (S2 level) for the management of DH (see Appendix).

CONCLUSION

These guidelines will improve the quality of management of DH and support dermatologists in their diagnostic and therapeutic decisions.

Prevalence of celiac disease in Iranian patients with type 1 diabetes: A systematic review and meta-analysis

Patients with type 1 diabetes mellitus (T1DM) are at high risk for celiac disease (CD) due to the common genetic background and interaction between environmental and immunological factors. The purpose of this systematic review and meta-analysis was to estimate the prevalence of CD among Iranian patients with type 1 diabetes. The search for articles was conducted using the following keywords: "celiac disease," "celiac," "coeliac disease," "diabetes," "Iran," and all other possible combinations of these terms. The following databases were searched from inception to June 2019: Scientific Information Database (SID), MagIran, Web of Science, PubMed, and Scopus. Meta-analysis was performed using the random-effects models, and the heterogeneity of results across the studies was assessed using the Cochran's Q test and quantified by the I² statistic. Data analysis was performed by Stata version 14. A total of 14 papers were included in the meta-analysis, involving 2030 Iranian patients with T1DM. The pooled prevalence of CD in patients with T1DM was 5% (95% CI 3-7). The prevalence of CD in Tehran (4%; 95% CI 1-6) was lower than in other provinces of the country (6%; 95% CI 4-8). Meta-regression analysis showed that, with increasing sample size, the prevalence of  CD was significantly reduced (p = 0.018).Given the adverse effects of CD , such as osteoporosis and malignancy (especially lymphoma), patients with T1DM must be screened for CD .

Early-life exposure to perfluorinated alkyl substances modulates lipid metabolism in progression to celiac disease

Celiac disease (CD) is a systemic immune-mediated disorder with increased frequency in the developed countries over the last decades implicating the potential causal role of various environmental triggers in addition to gluten. Herein, we apply determination of perfluorinated alkyl substances (PFAS) and combine the results with the determination of bile acids (BAs) and molecular lipids, with the aim to elucidate the impact of prenatal exposure on risk of progression to CD in a prospective series of children prior the first exposure to gluten (at birth and at 3 months of age). Here we analyzed PFAS, BAs and lipidomic profiles in 66 plasma samples at birth and at 3 months of age in the Type 1 Diabetes Prediction and Prevention (DIPP) study (n = 17 progressors to CD, n = 16 healthy controls, HCs). Plasma PFAS levels showed a significant inverse association with the age of CD diagnosis in infants who later progressed to the disease. Associations between BAs and triacylglycerols (TGs) showed different patterns already at birth in CD progressors, indicative of different absorption of lipids in these infants. In conclusion, PFAS exposure may modulate lipid and BA metabolism, and the impact is different in the infants who develop CD later in life, in comparison to HCs. The results indicate more efficient uptake of PFAS in such infants. Higher PFAS exposure during prenatal and early life may accelerate the progression to CD in the genetically predisposed children.

Lower HbA1c in patients with type 1 diabetes and celiac disease who reached celiac-specific antibody-negativity-A multicenter DPV analysis

OBJECTIVES

To study celiac-specific antibody status over 3 years in patients with type 1 diabetes and biopsy-proven celiac disease (T1D + CD). Furthermore, to determine clinical differences after diagnosis between patients reaching constant antibody-negativity (Ab-neg) and staying antibody-positive (Ab-pos).

METHODS

A total of 608 pediatric T1D + CD patients from the multicenter DPV registry were studied longitudinally regarding their CD specific antibody-status. Differences between Ab-neg (n = 218) and Ab-pos (n = 158) patients 3 years after biopsy were assessed and compared with 26 833 T1D patients without CD by linear and logistic regression adjusted for age, gender, diabetes duration and migration background.

RESULTS

Thirty-six percent of T1D + CD patients reached and sustained antibody-negativity 3 years after CD diagnosis. The median time until patients returned to Ab-neg was 0.86 (0.51;1.16) years. Three years after diagnosis, HbA1c was lowest in Ab-neg and highest in Ab-pos patients compared to T1D-only patients (adjusted mean (95%CI): 7.72 (7.51-7.92) % vs 8.44 (8.20-8.68) % vs 8.19 (8.17-8.21) %, adjusted P < 0.001, respectively). Total cholesterol, LDL-cholesterol and frequency of dyslipidemia were significantly lower in Ab-neg compared to T1D-only patients (167 (161-173) mg/dl vs 179 (178-179) mg/dl, P < .001; 90 (84-96) mg/dl vs 99 (98-99) mg/dl, P = .005; 15.7 (10.5-22.9) % vs 25.9 (25.2-26.6) %, P = .017). In longitudinal analyses over 6 years after diagnosis, a constantly higher HbA1c (P < .001) and a lower height-SDS (P = .044) was observed in Ab-pos compared to Ab-neg patients.

CONCLUSION

Only one third of T1D + CD patients reached constant Ab-negativity after CD diagnosis. Achieving Ab-negativity after diagnosis seems to be associated with better metabolic control and growth, supposedly due to a higher adherence to therapy in general.

Fibre-enriched buckwheat pasta modifies blood glucose response compared to corn pasta in individuals with type 1 diabetes and celiac disease: Acute randomized controlled trial

AIM

People with type 1 diabetes and celiac disease (T1D&CD) have high blood glucose variability. Processed gluten-free foods have shown to induce a worse metabolic profile whereas naturally gluten-free foods may represent healthier options. On the other hand, dietary fibre has shown to reduce postprandial glycemic excursions in individuals with diabetes. Thus, we evaluated the acute effect of fibre-enriched buckwheat (FBP) and corn pasta (CP) on postprandial blood glucose response (PP-BGR).

METHODS

Ten adult patients with T1D&CD consumed two meals with the same amount of carbohydrate while differing only for pasta type (FBP or CP) preceded by the same insulin bolus. Participants utilized continuous glucose monitoring (CGM) and data over 6 h after meal were analyzed.

RESULTS

PP-BGR differed between the two meals, being significantly lower in the first period (0-3 h) after the CP than the FBP meal (iAUC: -38 ± 158 vs. 305 ± 209 mmol/L · 180 min, p = 0.040), whereas significantly higher in the second period (3-6 h) after the CP than the FBP meal (iAUC: 432 ± 153 vs. 308 ± 252 mmol/L · 180 min, p = 0.030). Overall, a less variable postprandial profile was observed after FBP than CP consumption.

CONCLUSIONS

In individuals with T1D&CD, the acute consumption of FBP induces significant differences in PP-BGR compared with CP that may be clinically relevant.

Nutritional Considerations of the Gluten-Free Diet

Celiac disease (CD) is an autoimmune-related disease causing inflammation in the small intestine triggered by the ingestion of gluten in the diet. The gluten-free diet (GFD) is the only treatment. Nutritional deficiencies of macronutrients and micronutrients are frequently found in untreated or newly diagnosed CD. A registered dietitian nutritionist is uniquely qualified to educate on the GFD and assess and support nutritional status at diagnosis and long term as well as helping patients with nonresponsive CD. Quality of life is important to address in individuals with CD because the GFD affects all aspects of life.

Gluten-Free Diet: Gaps and Needs for a Healthier Diet

The gluten-free diet (GFD) is currently the only effective treatment in remitting the symptoms of coeliac disease (CD), a chronic systemic autoimmune disorder caused by a permanent intolerance to gluten proteins in genetically susceptible individuals. The diet entails the substitution of gluten-containing products with gluten-free-rendered products. However, over recent decades the nutritional profile of gluten-free (GF) food products has been increasingly questioned within the scientific community. The aim of this paper is to review the nutritional profile of gluten-free-rendered products currently available on the market, and discuss the possible relationship thereof with the nutritional status of coeliac patients on a GFD. Key inadequacies of currently available GF products are low protein content and a high fat and salt content. More adequate levels of dietary fiber and sugar than in the past have been reported. Population studies confirmed the above mentioned inadequacies. Further efforts are required to conceive adoptable interventions for product development and reformulation in order to achieve compliance with nutritional recommendations.

A Review on the Gluten-Free Diet: Technological and Nutritional Challenges

Consumers, food manufacturers and health professionals are uniquely influenced by the growing popularity of the gluten-free diet. Consumer expectations have urged the food industry to continuously adjust and improve the formulations and processing techniques used in gluten-free product manufacturing. Health experts have been interested in the nutritional adequacy of the diet, as well as its effectiveness in managing gluten-related disorders and other conditions. In this review, we aim to provide a clear picture of the current motivations behind the use of gluten-free diets, as well as the technological and nutritional challenges of the diet as a whole. Alternative starches and flours, hydrocolloids, and fiber sources were found to play a complex role in mimicking the functional and sensory effects of gluten in gluten-free products. However, the quality of gluten-free alternatives is often still inferior to the gluten-containing products. Furthermore, the gluten-free diet has demonstrated benefits in managing some gluten-related disorders, though nutritional imbalances have been reported. As there is limited evidence supporting the use of the gluten-free diet beyond its role in managing gluten-related disorders, consumers are urged to be mindful of the sensorial limitations and nutritional inadequacies of the diet despite ongoing strategies to improve them.

A quarter of patients with type 1 diabetes have co-existing non-islet autoimmunity: the findings of a UK population-based family study

Individuals with type 1 diabetes (T1D) are at increased risk of coeliac disease (CD), autoimmune thyroiditis and autoimmune gastritis, but the absolute risks are unclear. The aim of this study was to investigate the prevalence of autoantibodies to tissue transglutaminase (TGA), thyroid peroxidase (TPOA) and gastric H⁺ /K⁺ -ATPase (ATPA) and their genetic associations in a well-characterized population-based cohort of individuals with T1D from the Bart's-Oxford family study for whom islet autoantibody prevalence data were already available. Autoantibodies in sera from 1072 patients (males/females 604/468; median age 11·8 years, median T1D duration 2·7 months) were measured by radioimmunoassays; HLA class II risk genotype was analysed in 973 (91%) using polymerase chain reaction with sequence specific primers (PCR-SSP). The prevalence of TGA (and/or history of CD), TPOA and ATPA in patients was 9·0, 9·6 and 8·2%, respectively; 3·1% had two or more autoantibodies. Females were at higher risk of multiple autoimmunity; TGA/CD were associated with younger age and TPOA with older age. ATPA were uncommon in patients under 5 years, and more common in older patients. Anti-glutamate decarboxylase autoantibodies were predictive of co-existing TPOA/ATPA. TGA/CD were associated with human leucocyte antigen (HLA) DR3-DQ2, with the DR3-DQ2/DR3-DQ2 genotype conferring the highest risk, followed by DR4-DQ8/DR4-DQ8. ATPA were associated with DR3-DQ2, DRB1*0404 (in males) and the DR3-DQ2/DR4-DQ8 genotype. TPOA were associated with the DR3-DQ2/DR3-DQ2 genotype. Almost one-quarter of patients diagnosed with T1D aged under 21 years have at least one other organ-specific autoantibody. HLA class II genetic profiling may be useful in identifying those at risk of multiple autoimmunity.

Nutritional Consideration in Celiac Disease and Nonceliac Gluten Sensitivity

Celiac disease is an autoimmune disorder due to the inflammatory response to gluten in genetically predisposed individuals. It causes an enteropathy associated with several nutritional complications. Strict compliance to a gluten-free diet (GFD) is the current primary therapy. Nonceliac gluten sensitivity (NCGS) is a condition in which gluten ingestion leads to systemic symptoms but is not associated with small bowel atrophy or abnormal celiac serologies. A GFD heals celiac disease enteropathy and improves symptoms in NCGS. However, a long-term GFD can be associated with nutritional deficiencies and requires monitoring and guidance.

The Gut-Kidney Axis: Putative Interconnections Between Gastrointestinal and Renal Disorders

Diabetic kidney disease (DKD) is a devastating condition associated with increased morbidity and premature mortality. The etiology of DKD is still largely unknown. However, the risk of DKD development and progression is most likely modulated by a combination of genetic and environmental factors. Patients with autoimmune diseases, like type 1 diabetes, inflammatory bowel disease, and celiac disease, share some genetic background. Furthermore, gastrointestinal disorders are associated with an increased risk of kidney disease, although the true mechanisms have still to be elucidated. Therefore, the principal aim of this review is to evaluate the impact of disturbances in the gastrointestinal tract on the development of renal disorders.

Celiac disease microarray analysis based on System Biology Approach

AIM

Aim of this study is screen of the large numbers of related genes of CD to find the key ones.

BACKGROUND

Celiac disease (CD) is known as a gluten sensitive and immune system dependent disease. There are several high throughput investigations about CD but it is necessary to clarify new molecular aspects mechanism of celiac.

METHODS

Whole-genome profile (RNA) of the human peripheral blood mononuclear cells (PBMCs) as Gene expression profile GSE113469 was retrieved Gene Expression Omnibus (GEO) database. The significant genes were selected and analyzed via protein-protein interaction (PPI) network by Cytoscape software. The key genes were introduced and enriched via ClueGO to find the related biochemical pathways.

RESULTS

Among 250 significant genes 47 genes with expressed change above 2 fold change (FC) were interacted and the constructed network were analyzed. The network characterized by poor connections so it was promoted by addition 50 related nodes and 18 crucial nodes were introduced. Two clusters of biochemical pathways were identified and discussed.

CONCLUSION

There is an obvious conflict between microarray finding and the well-known related genes of CD. This problem can be solve by more attention to the interpretation of PPI ntwork analysis results.

The Impact of Diet Wheat Source on the Onset of Type 1 Diabetes Mellitus-Lessons Learned from the Non-Obese Diabetic (NOD) Mouse Model

Nutrition, especially wheat consumption, is a major factor involved in the onset of type 1 diabetes (T1D) and other autoimmune diseases such as celiac. While modern wheat cultivars possess similar gliadin proteins associated with the onset of celiac disease and T1D, alternative dietary wheat sources from Israeli landraces and native ancestral species may be lacking the epitopes linked with T1D, potentially reducing the incidence of T1D. The Non-Obese Diabetic (NOD) mouse model was used to monitor the effects of dietary wheat sources on the onset and development of T1D. The effects of modern wheat flour were compared with those from either T. aestivum, T. turgidum spp. dicoccoides, or T. turgidum spp. dicoccum landraces or a non-wheat diet. Animals which received wheat from local landraces or ancestral species such as emmer displayed a lower incidence of T1D and related complications compared to animals fed a modern wheat variety. This study is the first report of the diabetogenic properties of various dietary wheat sources and suggests that alternative dietary wheat sources may lack T1D linked epitopes, thus reducing the incidence of T1D.

Exceptional manifestation of polyautoimmunity in a very young girl - a case report

Polyautoimmunity is defined as the presence of more than one autoimmune disease in a single patient. The exact pathogenic mechanisms responsible for the coexistence of distinct autoimmune diseases within an individual have not been clearly explained. We report a case of a very young girl with the extremely rare co-existence of four distinct autoimmune diseases i.e. juvenile idiopathic arthritis, type 1 diabetes mellitus, coeliac disease and autoimmune hepatitis, recognized based on validated international classification criteria. The best to our knowledge there has been no case reporting coexistence of these particular four disorders in an individual. Moreover, all these diseases occurred during first three years of life, which also cause that case unique. Molecular studies of human leukocyte antigen (HLA) class II in our patient showed the presence of the HLA DRB1*01, HLA DRB1*03, HLA DQB1*02, HLA DQB1*05 molecules, which may suggest immunogenetic links between those autoimmune diseases. The presented case highlights the importance of active screening for other autoimmune diseases, if a patient with one autoimmune disease manifests with new or nonspecific symptoms.

Mediterranean diet-gene interactions: A targeted metabolomics study in Greek-Cypriot women

SCOPE

A high adherence to the Mediterranean diet (MD) was previously associated with a decreased risk of breast cancer (BC) among Greek-Cypriot women. Additionally, particular polymorphisms were shown to modulate this MD-BC association. Herein, we aimed to investigate the effect of polymorphisms-MD interactions on the levels of specific metabolites that could be related to dietary adherence or enzymatic activity, which is itself modulated by polymorphisms.

METHODS AND RESULTS

Greek-Cypriot women who were BC controls and had the lowest or the highest MD adherence (vegetables, fruit, legumes, fish) as assessed by principal component analysis (n = 564) were included. Participants were previously genotyped for nine polymorphisms of the one-carbon metabolism, oxidative stress, and xenobiotic metabolism. The serum levels of 14 metabolites that are key players in the aforementioned pathways were measured by UPLC-MS/MS. ANCOVA was used to assess polymorphism-MD interactions on metabolites' levels within a multivariate linear regression model. Statistically significant interactions between GSTM1 (where GST is glutathione S-transferase) deletion polymorphism and MD on flavin mononucleotide and on 5-methyltetrahydrofolate (5-MTHF) concentrations were observed. The MTHFR rs1801133 interacted significantly with MD on 5-MTHF concentration.

CONCLUSION

Serum levels of flavin mononucleotide and 5-MTHF were shown to be influenced by interactions between GSTM1 deletion or MTHFR (rs1801133) polymorphisms and a dietary pattern, characteristic of MD.

Celiac disease and the risk of kidney diseases: A systematic review and meta-analysis

BACKGROUND/OBJECTIVES

Previous epidemiologic studies attempting to demonstrate the risk of kidney diseases among patients with celiac disease (CD) have yielded inconsistent results. This meta-analysis was conducted with the aims to summarize all available evidence.

METHODS

A literature search was performed using MEDLINE and EMBASE from inception to May 2016. Studies that provided relative risks, odd ratios, or hazard ratios examining the risk of kidney diseases among patients with CD versus individuals without CD were included. Pooled risk ratios (RR) and 95% confidence interval (CI) were calculated using a random-effect, generic inverse variance method.

RESULTS

Eight studies met our eligibility criteria and were included in our analysis. A pooled RR of overall kidney diseases in patients with CD was 2.01 (95% CI, 1.44-2.81, I²=76%). The pooled RR of end-stage renal disease in patients with CD was 2.57 (95% CI, 2.03-3.24). Subgroup analyses showed that significant risks were increased for diabetic nephropathy (pooled RR of 1.49, 95% CI, 1.09-2.02) and IgA nephropathy (pooled RR of 2.62, 95% CI, 1.27-5.42) in patients with CD.

CONCLUSIONS

Our study demonstrates a significantly increased risk of kidney diseases among patients with CD. These findings may influence clinical management and primary prevention of kidney diseases in patients with CD.

Prevalence of celiac disease in Indian children with type 1 diabetes

BACKGROUND

Type 1 diabetes (T1D) patients are at an increased risk of having celiac disease (CD). We evaluated the prevalence and clinical profile of CD in children and adolescents with T1D and reviewed the Indian literature to determine prevalence and reasons for variability.

METHODS

In this cross-sectional study, subjects with T1D were prospectively evaluated with a demographic and gastrointestinal (GI) questionnaire, human IgA-tissue transglutaminase (IgA-tTGA), and endoscopic duodenal biopsy in serology positive patients. Studies evaluating prevalence of CD in T1D from India were reviewed.

RESULTS

Fourteen (13.6 %) of the 103 (52 boys, 13 years [2-20]) T1D patients were IgA-tTGA (182 U [47-300]) positive and 3.8 % (4/103) had villous atrophy on histology. Subjects with T1D and CD (n = 4) were younger at onset of T1D (32.5 ± 12.6 vs. 110.5 ± 53.8 months; p < 0.005) and more often had GI symptoms (pain abdomen [2/4 vs. 6/89; p = 0.01], stool frequency of 2-3/day [3/4 vs. 38/89; p = 0.004]) than screen negative T1D (n = 89). Growth and glycemic control were not different between the groups. In the 7 Indian studies involving 915 children and adults, 13.8 % (8 % to 17.8 %) T1D were serology positive. Prevalence of CD was reported as 6.9 % (2.3 % to 11.1 %), but only 3.1 % (2.3 % to 4.2 %) had villous atrophy on histology.

CONCLUSIONS

Potential CD and CD were present in 13.6 % and 3.8 % children with T1D respectively. T1D with CD have onset of diabetes at younger age and were more often symptomatic than screen negative T1D.

Effect of Associated Autoimmune Diseases on Type 1 Diabetes Mellitus Incidence and Metabolic Control in Children and Adolescents

Type 1 diabetes mellitus (T1DM) is one of the most common chronic diseases developing in childhood. The incidence of the disease in children increases for unknown reasons at a rate from 3 to 5% every year worldwide. The background of T1DM is associated with the autoimmune process of pancreatic beta cell destruction, which leads to absolute insulin deficiency and organ damage. Complex interactions between environmental and genetic factors contribute to the development of T1DM in genetically predisposed patients. The T1DM-inducing autoimmune process can also affect other organs, resulting in development of additional autoimmune diseases in the patient, thereby impeding diabetes control. The most common T1DM comorbidities include autoimmune thyroid diseases, celiac disease, and autoimmune gastritis; additionally, diabetes can be a component of PAS (Polyglandular Autoimmune Syndrome). The aim of this review is to assess the prevalence of T1DM-associated autoimmune diseases in children and adolescents and their impact on the course of T1DM. We also present suggestions concerning screening tests.

Gut Microbiota and Celiac Disease

Recent evidence regarding celiac disease has increasingly shown the role of innate immunity in triggering the immune response by stimulating the adaptive immune response and by mucosal damage. The interaction between the gut microbiota and the mucosal wall is mediated by the same receptors which can activate innate immunity. Thus, changes in gut microbiota may lead to activation of this inflammatory pathway. This paper is a review of the current knowledge regarding the relationship between celiac disease and gut microbiota. In fact, patients with celiac disease have a reduction in beneficial species and an increase in those potentially pathogenic as compared to healthy subjects. This dysbiosis is reduced, but might still remain, after a gluten-free diet. Thus, gut microbiota could play a significant role in the pathogenesis of celiac disease, as described by studies which link dysbiosis with the inflammatory milieu in celiac patients. The use of probiotics seems to reduce the inflammatory response and restore a normal proportion of beneficial bacteria in the gastrointestinal tract. Additional evidence is needed in order to better understand the role of gut microbiota in the pathogenesis of celiac disease, and the clinical impact and therapeutic use of probiotics in this setting.

Organ-specific autoimmunity in relation to clinical characteristics in children with long-lasting type 1 diabetes

BACKGROUND

The aim of this study was to assess the prevalence of diabetes and other organ-specific autoantibodies (Ab) associated with various autoimmune conditions, in Polish children with type 1 diabetes mellitus (T1DM).

METHODS

In this study 114 patients, aged 13.4 years, with mean diabetes duration 5.2 years were included. Ab to islet cell antigens: glutamic acid decarboxylase (GAD), insulinoma antigen 2 (IA-2), zinc transporter 8 (ZnT8), together with thyroid peroxidase Ab (TPO Ab), thyroglobulin Ab (Tg Ab), tissue transglutaminase Ab (tTG Ab) and 21-hydroxylase Ab (21-OH Ab) were measured.

RESULTS

The prevalence of at least one diabetes associated Ab was found in 87%, with the highest prevalence of 64% for ZnT8 Ab. In patients with disease duration <5 years, at least one antibody was present in 90%, the most prevalent was ZnT8 Ab (72%). In patients with duration >10 years, 50% had at least one antibody. The prevalence of other than islet cell autoimmunity was high (34%). Thyroid Ab were detected in 26% patients, 42% in girls vs. 8% in boys, p<0.001. tTG Ab were found in 11% patients, with a greater prevalence in children with early onset (p=0.01). 21-OH Ab were found in 2.6% T1DM patients.

CONCLUSIONS

Islet Ab were found in most T1DM children and remained positive even 10 years after onset. ZnT8 Ab emerged as an important marker for the diagnosis of T1DM in the Polish children. Screening for non-diabetes Ab in T1DM may be helpful in identifying subclinical cases of autoimmune thyroid, celiac or Addison's disease (AD).

A nationwide population-based study on the risk of coma, ketoacidosis and hypoglycemia in patients with celiac disease and type 1 diabetes

AIMS

Celiac disease (CD) may influence metabolic control in type 1 diabetes (T1D). This work examines whether CD in T1D influences hospital admissions due to coma, ketoacidosis and hypoglycemia.

METHODS

In population-based cohort study, individuals with CD were identified using biopsy data (1969-2008) from Sweden's 28 pathology departments. T1D was defined as a recorded diagnosis of T1D at age ≤30 years in the Swedish National Patient Register between 1964 and 2009. In total, 906 individuals had both T1D and CD and were matched for sex, age and calendar period with 4303 reference individuals. Through stratified Cox regression analysis, we modeled CD as a time-dependent covariate and estimated the risk of future coma, ketoacidosis and hypoglycemia, defined by relevant international classification of disease codes among T1D patients with and without CD.

RESULTS

During follow-up, patients with both T1D and CD had 49 hospital admissions with diabetic coma, 91 episodes of ketoacidosis and 25 hypoglycemic events. Among patients with T1D, CD did not influence the risk of coma (adjusted HR 0.97; 95 % CI 0.72-1.32), ketoacidosis (adjusted HR 1.08; 95 % CI 0.86-1.34), or hypoglycemia (adjusted HR 1.34; 95 % CI 0.87-2.05). The absolute risk of coma was 621/100,000 person-years in T1D and CD (637 in controls). Corresponding figures for ketoacidosis were 1175/100,000 person-years in T1D and CD (1092 in controls) and for hypoglycemia 316/100,000 person-years (236 in controls). HRs for metabolic emergencies in T1D were similar in the first 5 years after T1D diagnosis as thereafter.

CONCLUSIONS

Having a diagnosis of CD is unlikely to influence the risk of coma, ketoacidosis and hypoglycemia in T1D patients.

Practical insights into gluten-free diets

Coeliac disease is a global disease, and the only currently available treatment is a gluten-free diet (GFD). Although conceptually simple, the diet changes are substantial and have a profound effect on a patient's life. Untreated coeliac disease is associated with complications, including excess mortality, most of which can be avoided with a strict GFD. However, there are many barriers, including availability, cost and safety of gluten-free foods, and gluten cross-contamination. The GFD can be restrictive in social situations, leading to poor quality of life and, ultimately, nonadherence. As the number of patients with coeliac disease increases worldwide, clinicians need to be aware of the challenges patients face. Heightened awareness by physicians, dietitians and other providers can help maximize successful treatment, improve outcomes, and reduce health-care costs and disease burden. Routine follow-up is necessary to reinforce the need for a GFD, provide social and emotional support, and achieve mucosal healing, leading to reduced risk of complications. Unfortunately, there is wide variation in follow-up practices. The objective of this Review is to increase awareness of the challenges, management and follow-up of patients with coeliac disease to help them achieve GFD adherence and prevent complications whilst preserving their quality of life.

Coeliac disease and autoimmune disease-genetic overlap and screening

Coeliac disease is a treatable, gluten-induced disease that often occurs concurrently with other autoimmune diseases. In genetic studies since 2007, a partial genetic overlap between these diseases has been revealed and further insights into the pathophysiology of coeliac disease and autoimmunity have been gained. However, genetic screening is not sensitive and specific enough to accurately predict disease development. The current method to diagnose individuals with coeliac disease is serological testing for the presence of autoantibodies whilst the patient is on a regular, gluten-containing diet, followed by gastroduodenoscopy with duodenal biopsy. Serological test results can also predict the probability of coeliac disease development, even if asymptomatic. In patients with autoimmune diseases known to occur alongside coeliac disease (particularly type 1 diabetes mellitus or thyroid disorders), disease screening-and subsequent treatment if coeliac disease is detected-could have beneficial effects on progression or potential complications of both diseases, owing to the effectiveness of gluten-free dietary interventions in coeliac disease. However, whether diagnosis of coeliac disease and subsequent dietary treatment can prevent autoimmune diseases is debated. In this Review, the genetic and immunological features of coeliac disease, overlap with other autoimmune diseases and implications for current screening strategies will be discussed.

Co-occurrence of type 1 diabetes mellitus and celiac disease

The co-occurrence of celiac disease (CD) and type 1 diabetes (T1DM) has been reported as 5-7 times more prevalent than CD alone. The clinical presentation and natural history of CD in patients with T1DM may vary considerably. Less than 10% of patients with T1DM and CD show gastrointestinal symptoms. Therefore, experts support screening for CD in T1DM patients, though there is no consensus as to the recommended frequency of screening. When stratified by time since CD diagnosis, longer follow-up and coexistence of CD are associated with significant increased risk of diabetic associated morbidity and mortality. Early CD diagnosis and treatment with a gluten-free diet are essential.

Parent experiences raising young people with type 1 diabetes and celiac disease

Authors of this qualitative descriptive study interviewed 30 parents concerning their experiences raising a child or adolescent with type 1 diabetes (T1D) and celiac disease (CD). Analysis revealed six themes: (a) health complications of T1D, (b) challenges of daily disease management, (c) financial concerns, (d) the young person's emotional/mental health, (e) experiences with healthcare providers, and (f) experiences with people outside the family and at school. Results suggest nurses need to be sensitive to challenges young people living with T1D and CD and their parents face, conduct ongoing assessments, and provide time during interactions to adequately address concerns.

The role of gut microbiota in the development of type 1, type 2 diabetes mellitus and obesity

Diabetes is a group of metabolic disorders characterized by persistent hyperglycemia and has become a major public health concern. Autoimmune type 1 diabetes (T1D) and insulin resistant type 2 diabetes (T2D) are the two main types. A combination of genetic and environmental factors contributes to the development of these diseases. Gut microbiota have emerged recently as an essential player in the development of T1D, T2D and obesity. Altered gut microbiota have been strongly linked to disease in both rodent models and humans. Both classic 16S rRNA sequencing and shot-gun metagenomic pyrosequencing analysis have been successfully applied to explore the gut microbiota composition and functionality. This review focuses on the association between gut microbiota and diabetes and discusses the potential mechanisms by which gut microbiota regulate disease development in T1D, T2D and obesity.

Policaptil Gel Retard significantly reduces body mass index and hyperinsulinism and may decrease the risk of type 2 diabetes mellitus (T2DM) in obese children and adolescents with family history of obesity and T2DM

Background

Treatments for childhood obesity are critically needed because of the risk of developing co-morbidities, although the interventions are frequently time-consuming, frustrating, difficult, and expensive.

Patients and methods

We conducted a longitudinal, randomised, clinical study, based on a per protocol analysis, on 133 obese children and adolescents (n = 69 males and 64 females; median age, 11.3 years) with family history of obesity and type 2 diabetes mellitus (T2DM). The patients were divided into three arms: Arm A (n = 53 patients), Arm B (n = 45 patients), and Arm C (n = 35 patients) patients were treated with a low-glycaemic-index (LGI) diet and Policaptil Gel Retard®, only a LGI diet, or only an energy-restricted diet (ERD), respectively. The homeostasis model assessment of insulin resistance (HOMA-IR) and the Matsuda, insulinogenic and disposition indexes were calculated at T₀ and after 1 year (T₁).

Results

At T₁, the BMI-SD scores were significantly reduced from 2.32 to 1.80 (p < 0.0001) in Arm A and from 2.23 to 1.99 (p < 0.05) in Arm B. Acanthosis nigricans was significantly reduced in Arm A (13.2% to 5.6%; p < 0.05), and glycosylated-haemoglobin levels were significantly reduced in Arms A (p < 0.005). The percentage of glucose-metabolism abnormalities was reduced, although not significantly. However, the HOMA-IR index was significantly reduced in Arms A (p < 0.0001) and B (p < 0.05), with Arm A showing a significant reduction in the insulinogenic index (p < 0.05). Finally, the disposition index was significantly improved in Arms A (p < 0.0001) and B (p < 0.05).

Conclusions

A LGI diet, particularly associated with the use of Policaptil Gel Retard®, may reduce weight gain and ameliorate the metabolic syndrome and insulin-resistance parameters in obese children and adolescents with family history of obesity and T2DM.

Levels of circulating TNF-related apoptosis-inducing ligand in celiac disease

It has previously been demonstrated that the circulating levels of TNF-related apoptosis-inducing ligand (TRAIL) are significantly lower in patients with type 1 diabetes (T1D) than in normal age- and gender-matched controls. Since celiac disease (CD) is often associated with T1D, a retrospective study was performed to analyze the sera of a cohort of pediatric subjects: i) patients with CD at onset (n=100); ii) patients with potential CD (n=45); iii) patients with CD associated with other auto-immune diseases (n=17); and iv) patients with eosinophilic esophagitis (n=15). Among the patients with CD, 49 were also analyzed after six months on a gluten-free diet, while data were also available for 13 patients after one year on a gluten-free diet. No significant differences were found in the circulating levels of TRAIL between the patients with CD and the patients with either eosinophilic esophagitis or potential CD. Patients with CD associated with other auto-immune diseases showed significantly lower levels of TRAIL when compared with patients with CD alone. The gluten-free diet did not significantly modify the levels of circulating TRAIL at 6 or 12 months. Thus, although T1D and CD share common immunological features, the circulating levels of TRAIL show a significant difference between the two pathologies, and do not appear to be modulated in CD.

Systematic review with meta-analysis: associations between coeliac disease and type 1 diabetes

BACKGROUND

In the past decade, a number of population-based studies have examined the prevalence of coeliac disease in individuals with type 1 diabetes but prevalences have differed considerably.

AIM

To examine the prevalence of coeliac disease in individuals with type 1 diabetes.

METHODS

A systematic review of English-language articles published in PubMed Medline between 2000 and May 2014. Search terms included 'celiac disease' or 'coeliac disease' and 'diabetes mellitus'. Studies were selected with at least 100 individuals with type 1 diabetes being screened for coeliac disease where the coeliac diagnosis was later confirmed through small intestinal biopsy. Data synthesis used random-effects inverse variance-weighted models, and metaregression was used to examine heterogeneity in subgroups.

RESULTS

A pooled analysis, based on 26,605 patients with type 1 diabetes, found a prevalence of biopsy-confirmed coeliac disease of 6.0% (95% CI = 5.0-6.9%). Heterogeneity was large (I(2) = 93.2%). The prevalence was lower in adults with type 1 diabetes (2.7%), and in mixed populations with both children and adults with type 1 diabetes (4.7%) than in children (6.2%) with type 1 diabetes (P < 0.001). Additional subgroup analyses could not explain the large variation in coeliac disease prevalence between studies.

CONCLUSION

More than one in twenty patients with type 1 diabetes have biopsy-verified coeliac disease. This prevalence is high enough to motivate screening for coeliac disease among patients with type 1 diabetes.

Type 1 diabetes and celiac disease: clinical overlap and new insights into disease pathogenesis

Type 1 diabetes (T1D) and celiac disease (CD) are autoimmune diseases with clinical and pathogenic overlap. The mean prevalence of CD in patients with T1D is about 8 %. Classic intestinal symptoms of CD may not be present in T1D leading to the recommendation for active case finding in this higher risk group. Screening is done with sensitive and specific serologies including tissue transglutaminase (tTG) IgA and deaminated gliadin peptide (DGP) IgA and IgG. Positive serologies are confirmed by the presence of villous atrophy and increased intraepithelial lymphocytes on duodenal biopsy. A strict gluten free diet is recommended, although this can pose challenges for T1D patients who already have dietary restrictions. In aggregate, it appears as if the gluten free diet may help T1D management. T1D and CD have overlapping genetic and environmental risk factors. Among these, non-HLA genetic factors and the gut microbiome are among recent developments that will be discussed in this review.

Epitope mapping of the N-terminal portion of tissue transglutaminase protein antigen to identify linear epitopes in celiac disease

Celiac disease (CD) is an autoimmune mediated disease with complex and multifactorial etiology. Gluten intake triggers a composite immune response involving T-cells and B-cells and leading to the secretion of autoantibodies if a genetic predisposition is present. Untreated CD patients show high levels of circulating autoantibodies directed to different auto-antigens present in the intestinal mucosa. The most important auto-antigen is the endomysial enzyme tissue transglutaminase (tTG). Both IgA and IgG antibody isotypes to tTG are known, but only the IgA antibodies demonstrate the highest disease specificity and thus are considered disease biomarkers. Because the pathogenicity and exact tTG binding properties of these autoantibodies are still unclear, the characterization of tTG antigenic domains is a crucial step in understanding CD onset and the autoimmune pathogenesis. Overlapping peptide libraries can be used for epitope mapping of selected protein portions to determine antigenic fragments contributing to the immunological activity and possibly develop innovative peptide-based tools with high specificity and sensitivity for CD. We performed an epitope mapping study to characterize putative linear auto-antigenic epitopes present in the tTG N-terminal portion (1-230). A library of 23 overlapping peptides spanning tTG(1-230) was generated by Fmoc/tBu solid-phase peptide synthesis and screened by immunoenzymatic assays employing patients' sera. The results indicate that four synthetic peptides, that is, Ac-tTG(1-15)-NH2 , Ac-tTG(41-55)-NH2 , Ac-tTG(51-65)-NH2 , and Ac-tTG(151-165)-NH2 , are recognized by IgA autoantibodies circulating in CD patients' sera. These results offer important insight on the nature of the antigen-antibody interaction.

Cereal-based gluten-free food: how to reconcile nutritional and technological properties of wheat proteins with safety for celiac disease patients

The gluten-free diet is, to date, the only efficacious treatment for patients with Celiac Disease. In recent years, the impressive rise of Celiac Disease incidence, dramatically prompted changes in the dietary habit of an increasingly large population, with a rise in demand of gluten-free products. The formulation of gluten-free bakery products presents a formidable challenge to cereal technologists. As wheat gluten contributes to the formation of a strong protein network, that confers visco-elasticity to the dough and allows the wheat flour to be processed into a wide range of products, the preparation of cereal-based gluten-free products is a somehow difficult process. This review focuses on nutritional and technological quality of products made with gluten-free cereals available on the market. The possibility of using flour from naturally low toxic ancient wheat species or detoxified wheat for the diet of celiacs is also discussed.

Problems and challenges to adaptation of gluten free diet by Indian patients with celiac disease

Celiac disease is emerging in India and has become a public health problem. Almost 6-8 million Indians are estimated to have celiac disease. While there is a large pool of patients with celiac disease in India, until now, only a fraction of them have been diagnosed. With increasing awareness about celiac disease amongst health care providers and the general population, a massive increase in the number of patients with celiac disease is expected now and in the subsequent decade in India. While the number of patients with celiac disease is increasing, the country's preparedness towards the emerging epidemic of this disease is minimal. There are a number of issues, which requires urgent attention. Some of the key issues include increased awareness amongst health care professionals and the general public about the disease and its management, team-based management of patients with celiac disease, proper counseling and supervision of patients, training of dietitians in the management of patients with celiac disease, industrial production of reliable and affordable gluten-free food, and food labeling for gluten contents.
