Abstract
INTRODUCTION Life-long adherence to gluten-free diet (GFD) and its assessment is essential for patients with celiac disease (CeD). We have developed and validated a tool for assessing adherence to GFD which can be used by both physicians and dietitians. METHODS Phase 1: Development, content validation, and assessment of reliability of tool. Phase 2: Validation of tool against standard dietary evaluation (SDE) (gold standard), immunoglobulin A - anti-tissue transglutaminase antibodies (IgA anti-tTG Ab), and gluten immunogenic peptides in urine. Overall, 380 biopsy-confirmed patients with CeD (derivation cohort: n = 100 [phase 1], n = 210 [phase 2] and independent validation cohort, n = 70) were recruited. RESULTS Of an initial 90-point questionnaire, 84 items (Celiac Disease: Compliance Assessment Test [CD-CAT.v1]) were retained after content validation and pilot testing. In phase 1, upon administering CD-CAT.v1 on 100 patients, a comprehensive 35-item tool (CD-CAT.v2; α = 0.86) was obtained after removing items with low test-retest reliability and item-rest correlation values. In phase 2, upon administering CD-CAT.v2 on 210 patients, 22 items were removed having low correlation values (R < 0.4) with SDE. Finally, a 13-item tool (CD-CAT.v3; α = 0.84) was obtained with high criterion validity with SDE ( r = 0.806, P < 0.001), moderate convergent validity with celiac disease adherence test ( r = 0.602, P = 0.007), and moderate to weak correlation with urine gluten immunogenic peptides ( r = 0.46, P = 0.001) and IgA anti-tTG Ab ( r = 0.39, P = 0.008), respectively. The final 13-item tool also strongly correlated with SDE ( r = 0.78, P < 0.001) in an independent validation cohort of 70 patients with CeD. Principal component analysis identified 3 relevant subscales with a cumulative variance of 62%. The sensitivity and specificity of CD-CAT.v3 were 80% and 91%, respectively, with an area under curve of 0.905 with SDE. The obtained cutoff score of <19 from the receiver operating characteristic curve was further categorized as 13 = excellent, 14-18 = very good, 19-28 = average, and >28 = poor adherence to GFD. DISCUSSION CD-CAT is a new and rapid tool for monitoring dietary adherence to GFD with high sensitivity and specificity, which can be administered by both physicians and dietitians.

[PMID: 38790748 PMCID: PMC11119929 DOI: 10.3390/foods13101449] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/27/2024] [Revised: 04/17/2024] [Accepted: 05/06/2024] [Indexed: 05/26/2024] Open
Abstract
Celiac disease, an autoimmune disorder induced by the ingestion of gluten, affects approximately 1.4% of the population. Gluten damages the villi of the small intestine, producing symptoms such as abdominal pain, bloating and a subsequent loss of nutrient absorption, causing destabilization of the nutritional status. Moreover, gluten can trigger extra intestinal symptoms, such as asthma or dermatitis, but also mental disorders such as depression or anxiety. Moreover, people suffering from celiac disease sometimes feel misunderstood by society, mainly due to the lack of knowledge about the disease and the gluten-free diet. Thus, the treatment and follow-up of patients with celiac disease should be approached from different perspectives, such as the following: (1) a clinical perspective: symptomatology and dietary adherence monitorization; (2) nutritional assessment: dietary balance achievement; (3) psychological assistance: mental disorders avoidance; and (4) social inclusion: educating society about celiac disease in order to avoid isolation of those with celiac disease. The aim of this narrative review is to gain deep insight into the different strategies that currently exist in order to work on each of these perspectives and to clarify how the complete approach of celiac disease follow-up should be undertaken so that the optimum quality of life of this collective is reached.

Barriers at various levels of human ecosystem for maintaining adherence to gluten free diet in adult patients with celiac disease. Eur J Clin Nutr 2024; 78:320-327. [PMID: 38216646 DOI: 10.1038/s41430-024-01399-8] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/10/2023] [Revised: 12/06/2023] [Accepted: 01/02/2024] [Indexed: 01/14/2024]
Abstract
INTRODUCTION While lifelong and strict adherence to gluten-free diet (GFD) is essential for the successful treatment of celiac disease (CeD), only 30-50% of patients are able to maintain a good adherence to GFD. We determined factors influencing the adherence to GFD at various ecological levels including intra-personal, inter-personal, organizational, community and system-based levels in adult patients with CeD. METHODS A questionnaire to assess the adherence was developed and it was administered in the CeD clinic to patients with CeD on GFD for >1 year. Adherence to GFD was assessed in a subset of patients (n = 320) using Celiac Disease Adherence Test (CDAT). RESULTS Overall, 978 patients [median age: 29 years; females: 592] with CeD on GFD were recruited. They reported many barriers to adherence to GFD including intra-personal barriers such as lack of knowledge about GFD (19%), inadequate financial resources (27.2%) and lack of self-motivation/confidence (55.3%); inter-personal barriers such as intake of gluten-containing food upon forceful insistence of friends/family (23.4%); organizational barriers such as high cost (70.8%) and non-availability of GF-food products (48.6%); community-based barriers like consumption of gluten-containing food at religious occasions/festivals (11.1%) and social occasions (27.2%); and system-based barriers such as non-referral to dietitian for counseling (21.9%). As per CDAT, 204 (63.7%), 73(22.8%) and 43(13.4%) patients had good, average, and poor adherence to GFD, respectively. On multivariable analysis, occasional consumption of gluten, non-availability of GF-food while dining out and coercing by family and friends for consumption of GC-food were found to have highest odds for poor adherence to GFD. CONCLUSIONS Non-referral to a dietitian for counseling, irregular follow-up visits, unavailability of flour mill, non-supportive family/friends, high cost and limited availability of GF-food are the most common barriers to adherence to GFD. There is a need to create infrastructure and develop strategies to overcome these diverse barriers at various levels of ecosystem and thereby facilitate better adherence to GFD.

Abstract
BACKGROUND The purpose of this study was to understand the experiences of primary caretakers (PCTs) with a child diagnosed with celiac disease (CeD). There is paucity of research in understanding the experiences of PCTs of children with CeD in India. METHODS Purposive sampling was used to select PCTs of CeD-affected children from a tertiary hospital in New Delhi. Ten PCTs took part in the investigation. To gather the data, semi-structured interviews were held with participants. Hindi was used to administer the interviews. RESULTS The current study focused on the difficulties and worries PCTs experience in managing CeD. The main themes and sub-themes that emerged from the data were diagnosis of CeD (misdiagnosis of CeD, late diagnosis of CeD, feelings at the time of diagnosis, help from a doctor/nutritionist at the time of diagnosis); characteristics of CeD (CeD as a new disease, CeD as an allergy); attitude towards wheat (wheat as a poison, ignorance regarding negative effect of wheat); influence of significant others (making fun of the child, queries from others are a source of worry, non-acceptance of celiac disease by others and pressure to give gluten to the child); issues in following gluten-free diet (GFD) (fear of cross-contamination, distrust on GFD available outside home, GFD is expensive, making GFD is difficult, joint family, non-adherence to GFD, making non-GFD along with GFD); effect of CeD (financial effect of CeD, effect on physical and mental health of the child and PCT, effect on social life, change in family dynamics, eating restrictions); management of CeD (GFD for the whole family to manage CeD, family support to manage CeD, adhering to GFD, early diagnosis); and concerns (future marital concern for the child, cure of CeD, proper physical growth). CONCLUSION The current study gave an understanding of how PCTs dealt with a child's CeD. The difficulties and worries of caretakers should be taken into consideration and appropriate recommendations made to lessen the strain of managing the child's CeD and the daily obstacles associated with it.

Abstract
BACKGROUND The HLA associations of celiac disease (CD) in north Indians differ from that in Europeans. Our dietary gluten is among the highest in the world. Data on CD in people with diabetes (PWD) in north India is scant. OBJECTIVE To estimate the prevalence and clinical profile of CD in children with type 1 diabetes (T1D). RESEARCH DESIGN AND METHODS Retrospective review of case records of PWD with onset ≤18 years of age, registered between 2009 and 2020, having at least one anti tissue-transglutaminase (anti-tTG) serology report. RESULTS Of 583 registered PWD, 398 (68.2%) had celiac serology screening. A positive report was obtained in 66 (16.6%). Of 51 biopsied people, 22 (5.5%) were diagnosed to have CD, 12 in the first 2 years of diabetes onset. Symptomatic CD at diagnosis was seen in 63% (14/22). Age at diabetes onset (median [IQR] age 5.5 years, [2-12]) was lower in PWD and CD compared to PWD alone (10 years, [7-14], p < 0.016). Of 36 biopsied children with anti-tTG >100 au/ml, 20 (55.5%) had CD, while 2 out of 15 (13.3%) of those with lower anti-tTG titer had histopathology suggestive of CD. Of 23 seropositive children not diagnosed with CD, 5 of 8 with anti tTG >100 au/ml, and all 15 with lower anti-tTG, had normalization of titers over the 24 (10-41) months. CONCLUSIONS Our prevalence of CD is comparable to international data. Celiac disease was common with younger age at onset of T1D and higher titer of celiac serology. A high proportion was symptomatic of CD at diagnosis.

Abstract
Medical nutrition therapy (MNT) is a vital aspect of management of type 1 diabetes mellitus (T1DM) and should be tailored to ethnic and family traditions and the socioeconomic and educational status of the patient. In this article, we discuss the unique aspects of MNT in children and adolescents with T1DM in the Indian setting, with focus on the challenges faced by patients, dieticians and physicians and how these can be overcome. The authors reviewed the available literature on MNT in T1DM from India and prepared the document based on their vast collective clinical experience in treating patients with T1DM from different regions in India. Indian diets are predominantly carbohydrate-based with high glycemic index (GI) and low protein content. Various methods are available to increase the protein and fiber content and reduce the GI of food in order to limit glycemic excursions. Insulin regimens need to be tailored to the child's school timings, meal schedule, and the availability of a responsible adult to supervise/administer insulin. All patients, irrespective of economic and education background, should be taught the broad principles of healthy eating, balanced diet and carbohydrate counting. There are various barriers to dietary compliance, including joint family system, changing lifestyles, and other factors which need to be addressed. There is a need to customize dietary management according to patient characteristics and needs and develop standardized patient educational material on principles of healthy eating in various regional languages.

Gluten content in labeled and unlabeled gluten-free food products used by patients with celiac disease. Eur J Clin Nutr 2021; 75:1245-1253. [PMID: 33462461 DOI: 10.1038/s41430-020-00854-6] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/13/2020] [Revised: 12/12/2020] [Accepted: 12/17/2020] [Indexed: 02/07/2023]
Abstract
OBJECTIVE Gluten-free (GF) diet is the only reliable treatment for patients with celiac disease (CeD), but data on the extent of gluten contamination in GF food available in India is scanty. We evaluated gluten content in labeled, imported, and non-labeled GF food products currently available in the Indian market. METHODS Overall, 794 processed and commercially available packaged GF products (labeled GF (n = 360), imported GF (n = 80), and non-labeled/naturally GF (n = 354)) were collected from supermarkets of National Capital Region of India. Those unavailable in stores were purchased from e-commerce sites or directly from the manufacturers. Gluten level in them was determined by Ridascreen Gliadin sandwich R5 enzyme-linked immunosorbent assay (R-Biopharm AG, Germany). As per Codex Alimentarius and Food Safety and Standard Authority of India, "gluten free" labeled products must not contain > 20 mg/kg of gluten. RESULTS Overall, 10.1% of 794 GF products including 38 (10.8%) of 360 labeled and 42 (11.8%) of 354 non-labeled/naturally GF food products had gluten content > 20 mg/kg (range: 24.43-355 and 23.2-463.8 mg/kg, respectively). None of the imported GF products had gluten more than the recommended limits. Contaminated products most commonly belonged to cereal and their products (flours, coarse grains, pasta/macaroni, snack foods) pulse flours, spices, and bakery items. CONCLUSIONS A substantial proportion (10.1%) of GF food products (both labeled and non-labeled) available in India have gluten content greater than the prescribed limits of <20 mg/kg. Physicians, dietitians, support group, and patients with CeD should be made aware of this fact and regulatory bodies should ensure quality assurance.

Abstract
AIMS Lockdown and restricted mobility due to the pandemic of corona virus disease 2019 (COVID-19) has severely affected the continuity of healthcare of patients with acute and chronic diseases. We evaluated the impact of COVID-19 on the adherence to gluten-free diet (GFD), symptom control, and quality of life (QOL) in patients with celiac disease (CeD). METHODS A questionnaire, consisting of both ad-hoc and validated questions, was created after review of literature, group discussions, and expert meetings. Standardized questionnaires namely CeD adherence test (CDAT), celiac symptom index score, and CeD-related QOL were used. The web-based questionnaire was sent to 3130 patients via social media and 452 responses (14.4%) were received. Also, additional 68 patients (not available on any social media application) were interviewed telephonically by a trained dietitian. RESULTS Overall, 505 patients (females: 318; mean age: 24.1±14.2 years) were included. While only 6.7% (n = 34) had poor compliance to GFD (CDAT > 17) before COVID-19 pandemic, it almost doubled to 12.6% (n = 64) during the COVID-19 pandemic times (p = 0.02). Furthermore, 4.9% (n = 25) of patients were diagnosed contacting COVID-19. Interestingly, 73.2% (n = 370) patients preferred online appointment than physical appointment. Most common difficulties faced during lockdown period were high delivery charges for getting gluten-free (GF) food at home (54.4%), increased prices of regular GF food (43.1%), and travelling long distance to arrange GF food (44.9%). CONCLUSIONS The COVID-19 pandemic has substantially affected the adherence, symptom control, and QOL in patients with CeD, attributable to unavailability, shortage of money, and heightened cost of GF food. The pandemic has offered an opportunity to practice teleconsultation approach for patients with CeD.

Abstract
Although once considered uncommon, there is increasing recognition of celiac disease (CeD) in Asia. It is now clear that CeD is a disorder as frequent in certain Asian countries as that in western countries, although it often remains undiagnosed. With increasing awareness and diagnosis, the absolute numbers of celiac patients are expected to increase markedly in Asia. Asia, with 60% of the population of the world, is probably the major "reservoir" of undiagnosed CeD in the world. As Asia has a huge landscape along with highly heterogenous genetic, social, cultural, and nutritional practices, similar heterogeneity is seen in the epidemiology, diagnostic, and therapeutic facilities for CeD in Asia. In this article, we have reviewed the changes in the epidemiology, diagnostics, and management of CeD in Asia and summarized the challenges and opportunities for its emergence in Asia.

Abstract
Wheat is a major cereal crop providing energy and nutrients to the billions of people around the world. Gluten is a structural protein in wheat, that is necessary for its dough making properties, but it is responsible for imparting certain intolerances among some individuals, which are part of this review. Most important among these intolerances is celiac disease, that is gluten triggered T-cell mediated autoimmune enteropathy and results in villous atrophy, inflammation and damage to intestinal lining in genetically liable individuals containing human leukocyte antigen DQ2/DQ8 molecules on antigen presenting cells. Celiac disease occurs due to presence of celiac disease eliciting epitopes in gluten, particularly highly immunogenic alpha-gliadins. Another gluten related disorder is non-celiac gluten-sensitivity in which innate immune-response occurs in patients along with gastrointestinal and non-gastrointestinal symptoms, that disappear upon removal of gluten from the diet. In wheat allergy, either IgE or non-IgE mediated immune response occurs in individuals after inhalation or ingestion of wheat. Following a life-long gluten-free diet by celiac disease and non-celiac gluten-sensitivity patients is very challenging as none of wheat cultivar or related species stands safe for consumption. Hence, different molecular biology, genetic engineering, breeding, microbial, enzymatic, and chemical strategies have been worked upon to reduce the celiac disease epitopes and the gluten content in wheat. Currently, only 8.4% of total population is affected by wheat-related issues, while rest of population remains safe and should not remove wheat from the diet, based on false media coverage.

Abstract
Celiac disease, wheat sensitivity, and allergy represent three different reactions, which may occur in genetically predisposed individuals on the ingestion of wheat and derived products with various manifestations. Improvements in the disease diagnostics and understanding of disease etiology unveiled that these disorders are widespread around the globe affecting about 7% of the population. The only known treatment so far is a life-long gluten-free diet, which is almost impossible to follow because of the contamination of allegedly "gluten-free" products. Accidental contamination of inherently gluten-free products could take place at any level from field to shelf because of the ubiquity of these proteins/grains. Gluten contamination of allegedly "gluten-free" products is a constant threat to celiac patients and a major health concern. Several detection procedures have been proposed to determine the level of contamination in products for celiac patients. The present article aims to review the advantages and disadvantages of different gluten detection methods, with emphasis on the recent technology that allows identification of the immunogenic-gluten peptides without the use of antibodies. The possibility to detect gluten contamination by different approaches with similar or better detection efficiency in different raw and processed foods will guarantee the safety of the foods for celiac patients.

Abstract
BACKGROUND Coeliac disease is an autoimmune enteropathy characterised by mucosal inflammation subsequent to gluten exposure, leading to malabsorption. Treatment is strict dietary control, relying on the patient's ability to maintain lifestyle modifications. The present study aimed to compare clinical presentation and adherence to a gluten-free diet between South Asian and Caucasian patients with coeliac disease in East Lancashire METHODS: In total, 33 South Asian and 113 Caucasian adult patients diagnosed with coeliac disease under the care of the Dietetics Department at East Lancashire Hospitals NHS Trust were selected using a convenience sampling method and then allocated to the South Asian or Caucasian group. A subjective assessment of dietetic notes from follow-up visits within 1 year of the first appointment was undertaken by two investigators who subsequently allocated the patients to one of the three categories: (i) fully-adherent; (ii) partly-adherent; and (iii) non-adherent. Presenting complaint, vitamin D, vitamin B12 , folate and ferritin levels were also compared. RESULTS There was a significant difference in adherence to gluten-free diet between the groups, with a larger proportion of Caucasian patients being fully adherent to gluten-free diet compared to South Asian patients (64.6% versus 12.1%, P < 0.001). In addition, a significantly higher proportion of South Asian patients were vitamin D deficient compared with Caucasian patients (70.8% versus 32.8%, P = 0.002). CONCLUSIONS The rates of strict adherence to gluten-free diet and vitamin D levels were significantly lower in South Asian patients with coeliac disease compared to the Caucasian coeliac population. Further studies are required to investigate the causes and improve adherence in the South Asian population.

Abstract
Coeliac disease (CD) develops in genetically susceptible individuals who, in response to unclear environmental triggers, develop an immune response triggered by gluten ingestion. It is now recognised as a global disease affecting about 0.7% of the world's population. The clinical presentation ranges from malabsorption to asymptomatic individuals diagnosed by screening high-risk groups. Diagnosis requires the demonstration of small intestinal villous atrophy in the presence of circulating coeliac auto-antibodies and/or an unequivocal response to a gluten-free diet (GFD). Recent guidelines suggest that, in a subset of children, duodenal biopsies can be avoided in the presence of strict symptomatic and serological criteria. While the majority of patients respond to a GFD, up to 20% of patients with CD have persistent or recurrent symptoms. There are several aetiologies for residual or new symptoms in a patient with CD on a GFD, with inadvertent exposure to gluten being the most common. Following a GFD can be challenging for patients with CD and understanding the barriers/challenges faced by patients in maintaining a GFD is crucial for compliance.

Abstract
Coeliac disease (CD) is an autoimmune gastrointestinal disorder whereby the ingestion of gluten, a storage protein found in wheat, barley and rye, causes damage to intestinal mucosa with resultant malabsorption, increased risk of anaemia and osteoporosis. Worldwide estimates suggest 1% of the population have CD. With no cure, the only treatment is a gluten-free diet (GFD). Adhering to a GFD can be very challenging; it requires knowledge, motivation and modified behaviours. Assessing adherence to a GFD is methodologically challenging. This review aims to provide an overview of the literature reporting adherence to a GFD in people with CD and the methodological challenges encountered. From six studies it has been reported that rates of adherence to a GFD range between 45 and 90% in patients of different ethnicities with CD. GF dietary adherence can be influenced by age at diagnosis, coexisting depression, symptoms on ingestion of gluten, nutrition counselling, knowledge of GF foods, understanding of food labels, cost and availability of GF foods, receiving GF foods on prescription and membership of a coeliac society. To date only five intervention studies in adults with CD have been undertaken to improve GF dietary adherence. These have included dietary and psychological counselling, and the use of online training programmes, apps, text messages and telephonic clinics. Future interventions should include people of all ethnicities, consider patient convenience and the cost-effectiveness for the healthcare environment.

Abstract
The gluten-free diet is effective in the majority of celiac disease (CD) patients, but it is burdensome and may influence quality of life (QoL). The aim of the study was to analyze the social and emotional fears and worries influencing the QoL of female CD patients following a gluten-free (GF) diet, as well as to indicate the sociodemographic interfering factors. The study was conducted on a group of 251 female CD patients, while emotional, social and worries subscales of the Celiac Disease Questionnaire (CDQ) were applied, as well as purchase-related emotions and behaviors were assessed. Respondents declaring worse economic status obtained significantly lower scores in the emotional, social and worries subscales of the CDQ than respondents declaring better economic status, while for other factors (CD duration, GFD adherence, BMI, place of residence and educational level) no significant association was stated in the multi-factor analysis. Moreover, respondents declaring worse economic status more often declared that a bad mood affected their purchase decisions than did respondents declaring better economic status. It was stated, that the economic status of CD patient could be one of the most important factors influencing their social and emotional fears and worries. It may be supposed that low economic status may lead some CD patients to choose to relieve stress by purchasing GF products instead of other products.

Abstract
Gluten-free diet (GFD) is the only definitive treatment for patients with celiac disease (CeD). Strict adherence to GFD improves the symptoms, nutritional deficiencies, and the overall well-being of the patients. The management of CeD is truly different and unique from the treatment of other medical or surgical diseases. While prescribing a GFD is easy, the key to the success lies in the dietary counseling by a nutrition specialist/physician and maintenance of adherence to the prescribed diet by the patient. When restricting gluten from all possible sources, it is pertinent to recommend a diet that is healthy and balanced for patients with celiac disease. Those following GFD must be counseled properly on the ways of balancing their diets and of avoiding cross contamination. They should be taught how to read food labels properly and given tips for dining out or during traveling. Regular follow up with patients is required for assessing the compliance and monitoring growth and the status of recovery. In this review article, we have compiled, for the physicians and gastroenterologists, the relevant information about GFD including counseling, adherence, nutritional adequacy, and many other related issues.

Abstract
Background A gluten-free diet (GFD) is the standard of care in the management of patients with celiac disease, but clinical and histological recovery are often delayed. In newly diagnosed patients, strict compliance to GFD is difficult to achieve; this is especially true in developing countries where gluten-free food is often difficult to obtain. Steroids, when used alone, can be effective in inducing recovery in patients with celiac disease. We performed a randomized controlled trial to study the effect of a short course of prednisolone combined with a GFD on the recovery of celiac disease. Materials and methods This study was a single-center, randomised, open-label trial. This investigation was done in a pediatric gastroenterology unit of a tertiary teaching hospital in north India.Twenty-eight newly diagnosed celiac disease patients were enrolled in the study. Prednisolone was given at 1 mg/kg for four weeks; duodenal biopsies and IgA anti-tissue transglutaminase (tTg) levels were assessed at eight weeks, six months, and 12 months from the start of the study. Outcome measures The primary outcome measures used to indicate clinical, histological, and immunological recovery of celiac disease were clinical improvement at eight weeks and the proportion of patients with improved histology by at least one grade and who were tissue transglutaminase (tTg) seronegative at eight weeks. The secondary measures were the proportion of patients showing normalization of histological features and the proportions of patients becoming seronegative at six months and one year of GFD. Results Patients were randomized into the GFD only (n = 14) or GFD with prednisolone (GFD+P) (n = 14) groups. No significant differences were detected in clinical recovery at eight weeks; none of the patients became seronegative at eight weeks, six months, or 12 months. The proportion of patients with improvement in histology by at least one grade was higher in the GFD+P group at eight weeks, and there was no difference in overall histological improvement at 12 months after starting treatment. Conclusion The addition of a short course of prednisolone to a GFD does not affect clinical and serological recovery but might result in rapid histological recovery compared to a GFD alone in patients newly diagnosed with celiac disease.

Abstract
Proline- and glutamine-rich gluten proteins are one of the major constituents of cereal dietary proteins, which are largely resistant to complete cleavage by the human gastrointestinal (GI) digestive enzymes. Partial digestion of gluten generates approximately 35 amino acids (aa) immunomodulatory peptides which activate T-cell-mediated immune system, followed by immunological inflammation of mucosa leading to the onset of celiac disease (CD). CD is an autoimmune disease associated with HLA-DQ2/DQ8 polymorphism and dysbiosis of gut microbiota. CD is either diagnosed using duodenal mucosal biopsis or serological testing for transglutaminase 2 (TG2) specific antibodies (IgA and IgG). Current therapy for CD management is gluten-free diet, while other therapies like glutenase, probiotics, immunomodulation, jamming of HLA-DQ2, inhibition of TG2, and gluten tolerance aided by gluten tolerizing vaccines are being developed.

Abstract
Deficiencies of essential micronutrients such as iron and zinc are the cause of extensive health problems in developing countries. They adversely affect performance, productivity and are a major hindrance to economic development. Since many people who suffer from micronutrient deficiencies are dependent on staple crops to meet their dietary requirements, the development of crop cultivars with increased levels of micronutrients in their edible parts is becoming increasingly recognized as a sustainable solution. This is largely facilitated by genetics and genomic platforms. The cereal crop pearl millet (Pennisetum glaucum), is an excellent candidate for genetic improvement due to its ability to thrive in dry, semi-arid regions, where farming conditions are often unfavorable. Not only does pearl millet grow in areas where other crops such as maize and wheat do not survive, it contains naturally high levels of micronutrients, proteins and a myriad of other health benefitting characteristics. This review discusses the current status of iron and zinc deficiencies and reasons why interventions such as fortification, supplementation, and soil management are neither practicable nor affordable in poverty stricken areas. We argue that the most cost effective, sustainable intervention strategy is to biofortify pearl millet with enhanced levels of bioavailable iron and zinc. We discuss how naturally occurring genetic variations present in germplasm collections can be incorporated into elite, micronutrient rich varieties and what platforms are available to drive this research. We also consider the logistics of transgenic methods that could facilitate the improvement of the pearl millet gene pool.

Abstract
The purpose of the present work was both to analyze composition of Spanish celiac women and to study the food habits and gluten-free diet of these celiac patients, in order to determine whether they achieve a balanced and healthy diet as well as to highlight nutritional qualitative and/or quantitative differences. 54 adult celiac women (34 ± 13 years) took part in the six-month study. Height, weight and body composition were measured. An analysis of energy consumption and of the macronutrient distribution of their diet was carried out. Their fulfillment of micronutrient intake recommendations was verified. Participants showed a Body Mass Index of 21.6 ± 2.4 kg/m2. Energy Intake was slightly lower than the Dietary Reference Intakes. Excessive protein apart from over-consumption of fat was observed. More than three quarters of participants consumed meat in excess. Carbohydrate consumption along with that of fiber was below recommended levels. Vitamin D, iron, and iodine had a low percentage of recommendation compliance. In general, participants followed the recommendations of dairy products and fruit intake whereas vegetable consumption was not enough for the vast majority. We conclude that although the diet of celiac women does not differ much from the diet of general population, some considerations, such as reducing fat and protein consumption and increasing fiber intake, must be taken into account.
