BackgroundCeliac disease (CD) is a chronic autoimmune condition that, when left untreated, increases the risk of significant health challenges. The only medical treatment for CD is a strict gluten-free diet (GFD), which is behaviorally dependent. Despite quality of life (QOL) and adherence being impacted by the complicated and burdensome nature of the GFD, there exists a paucity of established behavioral interventions aimed to improve adherence and QOL in adolescents with CD.AimsDevelop and refine the Gluten-Free Resilience and Overall Wellness (GROW) Project, the first family-centered, online behavioral intervention to improve QOL and GFD self-management in adolescents with CD and their parents.MethodsStudy staff adapted and refined an existing online behavioral intervention for adults with CD. Two rounds of interviews with patient, parent, and clinician stakeholders were conducted to collect feedback and inform the final intervention structure and content. Qualitative interview data were analyzed using inductive content analysis.ResultsStakeholder feedback supported a group-based, virtual format across both rounds of interviews. Participants proposed format changes to the intervention to increase participant engagement. Content suggestions included enhancing information about reliable digital resources, building resilience, GFD and alcohol, and the scientific development of the program.ConclusionThe GROW Project addresses a critical need for interventions that strengthen behavioral self-management strategies in adolescents with CD and their families by providing virtual skill-building and psychoeducation that may improve family's QOL while managing CD and the GFD.

Celiac disease (CD) is a systemic autoimmune disorder triggered by gluten ingestion ingenetically predisposed individuals. It is characterized by intestinal histological damage and the production of specific autoantibodies. The latest European Society for Paediatric Gastroenterology, Hepatology, and Nutrition (ESPGHAN) 2020 guidelines have excluded human leukocyte antigen (HLA) genotyping from the no-biopsy diagnostic approach due to its weak positive predictive value, limited availability, and high cost in some countries. However, HLA genetic testing remains valuable in certain clinical contexts. This study provided practical indications for when to request and how to interpret HLA genotyping, emphasizing its continued relevance for CD diagnosis in specific cases. We also proposed a strategy for monitoring the risk of developing type 1 diabetes (T1D) in patients with CD, based on the risk stratification carried by different HLA genotypes. A retrospective analysis of 746 patients with CD and 627 controls was conducted at our hospital starting in 2012, when HLA genotyping became mandatory for the diagnosis of CD. We identified key clinical scenarios where HLA testing remains useful. Several high risk HLA-DQ genotypes strongly associated with CD were highlighted, including HLA-DQ2.5/HLA-DQ2.2 and HLA-DQ2.5/HLA-DQ2.5. Notably, while the HLA-DQ2.5/HLA-DQ2.2 genotype is linked to CD, it appears to confer protection against T1D. To support clinical practice, we presented a table clarifying commonly used HLA terminology, and another summarized the main clinical situations in which HLA genotyping should still be considered. These findings underscore the dual role of HLA testing: Not only can it help rule out CD in selected cases, but it also identifies patients with CD at risk for T1D, guiding personalized monitoring strategies.

In pediatric patients, celiac disease (CD) may influence the health-related quality of life (HRQoL).

The study aimed to assess HRQoL and further characterise the clinical factors associated with reduced HRQoL, in a large multicenter pediatric cohort with CD.

The disease-specific questionnaire CD Dutch Questionnaire (CDDUX) and the generic questionnaire Paediatric Quality of Life Inventory (PedsQL) were used to assess the HRQoL. Clinical and sociodemographic characteristics were analyzed, univariate and multivariate analysis were conducted.

Eleven different Italian pediatric centers and 871 families were involved. Mean age at interview was 12.9 ± 2.9 years. The mean total CDDUX score of CD patients was 47.1 ± 18.8, revealing a neutral HRQoL (47.1 ± 18.8), and a good to very good HRQoL according to the PedsQL (81.4 ± 12.6), parents indicated lower scores (p = 0.03) with both questionnaires (CDDUX 45.1 ± 18.6 and PedsQL 79.9 ± 14.5). Patients with lower HRQoL were mainly female, living in Northern Italy, with lower parent's education level and non-biopsy diagnosis of CD. In multivariate analysis, the main predictor of lower CDDUX score was non-biopsy diagnosis.

The HRQoL in a large cohort of Italian children is reported as neutral-good. This indicates a high level of adaptive behaviors in response to the daily challenges of CD. Parents tend to underestimate their children's HRQoL. Specific clinical factors, including non-biopsy diagnosis, may be associated to lower HRQoL.

In recent years, wheat- and gluten-free diets have increased in demand due to reported increases in various conditions reported to be driven by ingredients of these food products. Celiac disease, wheat allergy and non-celiac wheat sensitivity constitute the three main categories of wheat-related disorders. Celiac disease is a well-characterized immune-mediated disease caused by immune reaction against specific gliadin epitopes, the main protein in wheat. Screening studies of samples collected over time bring evidence that there is a true increase in prevalence not only driven by increased testing activity. Clinical presentation of CeD is diverse and there is an increased risk of autoimmune co-morbidities. Wheat allergy consists of IgE- and non-IgE-mediated reactions, driven by Th2-cells directing eosinophil and basophil responses. Rapid IgE-mediated reactions are characterized by specific IgE antibodies in conjunction with symptoms originating especially from the respiratory and gastrointestinal tract. There is an increased risk of other allergies and the majority recover during adolescence. Non-IgE-mediated wheat allergy is a less-well defined condition, which is often diagnostically challenging due to a longer interval between exposure and symptoms and lack of non-invasive biomarkers. In this condition, wheat as a trigger needs to be established by exclusion followed by dietary challenge. Non-celiac wheat sensitivity, despite being the most recently recognized, has the highest reported prevalence among the three wheat-related entities. It remains, however, particularly poorly characterized due to unclear pathophysiology and lack of diagnostic markers. This narrative review will scrutinize the shared and distinct clinical features of the three wheat-related conditions, focusing on epidemiology, clinical presentation, co-morbidities, diagnosis, treatment and prognosis.

Coeliac disease (CeD) is a chronic immune-mediated disease triggered by exposure to dietary gluten in genetically predisposed individuals. The burden of CeD on patients and the healthcare system remains poorly evaluated in Germany.

To assess the healthcare resource utilisation (HCRU) and costs of diagnosed CeD patients in a German claims database.

A retrospective CeD case-control study was conducted using German claims data between 2017 and 2021.

CeD diagnosis was defined by at least one inpatient or two outpatient diagnostic codes (International Statistical Classification of Diseases and Related Health Problems, 10th Revision, German Modification (ICD-10-GM) K90.0) within four quarters (irrespective of calendar year) for CeD during the study period. Controls (non-CeD patients) were matched in a ratio of 5:1 by age, Charlson Comorbidity Index, sex and region. HCRU (hospitalisations, outpatient visits, medication use, sick leaves) and healthcare costs (outpatient services, inpatient services, outpatient pharmaceuticals, sick leaves and aids and remedies) were compared between CeD patients and controls.

From the 3,352,188 patients with continuous enrolment during the study period (2017-2021), 8258 (0.25%) patients were identified as having a CeD diagnosis. The mean number of hospitalisations and outpatient visits within 5 years was 1.8- and 1.5-fold higher among matched CeD patients (n = 8243) compared to their controls (n = 41,215), resulting in an excess healthcare cost of €5251. Inpatient expenses were the main cost driver and accounted for 31.5% of total incremental costs.

The current study showed that CeD patients have considerably higher HCRU and related costs compared to matched controls. Our findings suggest the need for improved treatment options for CeD patients in addition to a gluten-free diet.

Celiac disease (CeD) affects 1-2% of the world's population. The aim of this study was to relate the incidence of CeD-related serological markers to symptoms, pathologies, and environmental exposure to wheat flour, given the number of flour mills present in the region.

Serum samples were collected from 537 inhabitants from a rural city. Levels of anti-transglutaminase (a-tTg), anti-gliadin, anti-DGP antibodies and total IgA levels were measured. Volunteers completed a questionnaire covering environmental factors, demographics, pregnancies, other diseases, symptoms, and CeD diagnosis. Geo-referencing of volunteers' homes and mills in the city was performed, and correlations between the different parameters assessed were analysed.

A CeD incidence of 1.76 % was found. However, a-tTg and a-gliadin levels were elevated in the population without CeD diagnosis (9.6 % and 30.1 %). Subjects with CD diagnosis showed diarrhoea and colic pain. Women with CeD had fewer pregnancies. Positive a-tTg and number of CeD-associated symptoms appear to correlate with proximity to flour mills.

A high prevalence of CeD-related specific antibody positivity in a rural population was found, possibly due to environmental factors related to flour mills. Further research is needed to better understand CeD's pathogenesis and its health implications.

Quinoa is an annual pseudocereal highly adapted to extreme environments and has become, at this point in time, an extremely popular food due to its exceptional and high nutritional quality. This study aims to investigate the association of quinoa salt tolerance at an early developmental stage with its grain nutritional value under the effect of severe climatic hurdles. The current findings revealed a significant variability between genotypes in salt response attributes at the first development stage, where genotypes Amarilla Sacaca (thereafter, A. Sacaca) and QQ57 exhibited high salt tolerance thresholds with a low salt sensitivity index (SI), and a high capacity for Na+ sequestration into vacuoles. A significant positive association was detected between salt tolerance degree and yield parameters, saponins (SAPs), and minerals contents, where genotype A. Sacaca exhibited the highest SAP content with 3.84 mg.g-1 and the highest amounts of K, Ca, P, and Fe. The analysis of fatty acid composition demonstrated a high significant negative correlation between crude fat content and salt SI, and between yield parameters. Despite its low harvest index (HI) and low seed oil content, the salt-tolerant genotype A. Sacaca showed a high nutritional quality for seed oil according to its lowest ω6/ω3 ratio (5.6/1) and lowest level of atherogenicity index (AI). The genotype 115R, defined as the most sensitive to salt stress, exhibited a high seed oil quality due to its low lipid peroxidation susceptibility as reflected by its oxidative susceptibility and peroxidizability indexes. The significance of this study includes the identification of valuable quinoa genotypes showing high efficiency in growth and yield under severe stress accompanied by a high nutritional value satisfying the market requirements for healthy, nutritious, and safe food products.

Celiac disease (CeD) has an estimated prevalence of 1%-3%. The classical clinical presentation is malabsorption, but now patients may present with more subtle symptoms such as constipation, osteoporosis, or iron deficiency anemia. Children may also present with poor growth.CeD has a strong genetic component, and high-risk groups include first-degree relatives with CeD, patients with co-existing autoimmune diseases, and patients with chromosomal aberrations.

Diagnostic tests for CeD include duodenal histology, serology, and genetic testing. Duodenal histology has traditionally been the gold standard of diagnosis. However, serological tests, especially IgA tissue transglutaminase antibodies (TTG-IgA), are widely used and diagnostic algorithms are based primarily on TTG-IgA as a starting point. Human leukocyte antigen typing may also be incorporated to determine genetic risk for CeD. Guidelines for children endorse biopsy avoidance provided high levels of TTG-IgA, with diagnostic accuracy being comparable to duodenal biopsy. Confirmation may be achieved by identifying IgA endomysial antibodies in a separate blood sample. Subjects with low positive TTG-IgA levels and subjects with IgA deficiency need a biopsy to establish a diagnosis of CeD. The clinical follow-up of CeD usually includes a repeat TTG-IgA examination. In adults, healing may be delayed or incomplete, and a rare consequence of refractory celiac disease is transformation to enteric T-cell lymphoma.

Laboratory testing, in particular TTG-IgA, plays a central role in the diagnosis and has an accuracy comparable to histology. Diagnostic algorithms utilizing laboratory testing are critical for the development of novel strategies to improve diagnosis.

The incidence of celiac disease (CD) has increased rapidly in the late 20th and early 21st centuries, but there are recent reports of rates levelling off in countries with a high prevalence. The aim of this study was to investigate current trends in CD in southern Sweden.

Children and adults diagnosed with CD by biopsy or serology in the region of Skåne, southern Sweden, from 2010-2022 were included. The home address was identified through registers to analyze temporal and geographical trends.

A total of 3218 CD-patients were identified (52.2% children), the vast majority detected in clinical care but a few children by screening studies. The age-standardized incidence rate was 18.6 cases/105. The incidence decreased at a rate of -0.75 cases/105 (95% CI -1.14 to -0.35, p 0.002). The incidence among girls under 18 years almost halved throughout the study period, decreasing by -2.94 cases/105 (95% CI -4.59 to -1.29, p 0.002), while there only were small changes among men. The most common age of onset was 3-9 years. CD incidence varied by place of living and was more common in small towns than urban or rural areas.

The incidence of CD in southern Sweden is decreasing, primarily in children and women who traditionally have had the highest risk of CD. CD was diagnosed most frequently in children 3-9 years old. There were regional variations in incidence. CD was most common in small towns, pointing to the importance of environmental factors in CD etiology.

Celiac disease (CeD) is an autoimmune disorder triggered by the immune response to gluten in genetically predisposed individuals. Recent research has unveiled a heightened risk of developing specific malignant neoplasms (MN) and various malignancies, including gastrointestinal, lymphomas, skin, and others, in individuals with CeD.

To investigate the prevalence of MN in hospitalized CeD patients in the United States.

Using data from the National Inpatient Sample spanning two decades, from January 2000 to December 2019, we identified 529842 CeD patients, of which 78128 (14.75%) had MN. Propensity score matching, based on age, sex, race, and calendar year, was employed to compare CeD patients with the general non-CeD population at a 1:1 ratio.

Positive associations were observed for several malignancies, including small intestine, lymphoma, nonmelanoma skin, liver, melanoma skin, pancreas myelodysplastic syndrome, biliary, stomach, and other neuroendocrine tumors (excluding small and large intestine malignant carcinoid), leukemia, uterus, and testis. Conversely, CeD patients exhibited a reduced risk of respiratory and secondary malignancies. Moreover, certain malignancies showed null associations with CeD, including head and neck, nervous system, esophagus, colorectal, anus, breast, malignant carcinoids, bone and connective tissues, myeloma, cervix, and ovary cancers.

Our study is unique in highlighting the detailed results of positive, negative, or null associations between different hematologic and solid malignancies and CeD. Furthermore, it offers insights into evolving trends in CeD hospital outcomes, shedding light on advancements in its management over the past two decades. These findings contribute valuable information to the understanding of CeD's impact on health and healthcare utilization.

Celiac disease (CeD) is a chronic autoimmune condition driven by gluten ingestion in genetically predisposed individuals, resulting in inflammatory lesions in the proximal small intestine. Although the presence of specific HLA-linked haplotypes and gluten consumption are necessary for disease development, they alone do not account for the variable onset of CeD in susceptible individuals. This review explores the multifaceted role of non-host factors in CeD development, including dietary and microbial influences. We discuss clinical associations and observations highlighting the impact of these factors on disease onset and severity. Furthermore, we discuss studies in CeD-relevant animal models that offer mechanistic insights into how diet, the microbiome, and enteric infections modulate CeD pathogenesis. Finally, we address the clinical implications and therapeutic potential of understanding these cofactors offering a promising avenue for preventive and therapeutic interventions in CeD management.

Celiac disease (CeD) is a chronic autoimmune disorder of global relevance, with the potential for acute and long-term complications. However, the economic burden of CeD is rarely considered and largely thought of as limited to the cost of gluten-free food. Fortunately, recent research has shed light on the various societal costs of CeD across the health care continuum. This article summarizes the current evidence on the economic impacts of CeD, which suggest that the societal economic burden of CeD stretches beyond the cost of gluten-free food. This review provides ample evidence of larger but hidden costs related to excess health care use for complications and comorbidities, as well as reduced productivity. Although significant advances are expected in the management of CeD, their effect on the economic burden of CeD remain uncertain. The aim of this review was to inform stakeholders across society and contribute to improved policies to support patients with CeD.

Celiac disease is one of the most common life-long disorders worldwide, with a prevalence mostly ranging between 0.7% and 2.9% in the general population and a higher frequency in females and well-defined at-risk groups, such as relatives of affected individuals and patients with autoimmune comorbidities. Increasing clinical detection is facilitated by improving awareness, implementation of a case-finding approach, and serology availability for screening at-risk patients, among other factors. Nevertheless, due to huge clinical variability, many celiac disease cases still escape diagnosis in most countries, unless actively searched by proactive policies. The burden of celiac disease is increasing, as is the need for better longitudinal care. Pediatric screening of the general population could represent the road ahead for an efficient intervention of secondary prevention aimed to reduce the social and health burden of celiac disease. This review analyses the epidemiology of celiac disease continent by continent, discusses current strategies to improve the detection of celiac disease, and highlights challenges related to the burden of celiac disease globally.

Globally, approximately 1.4% of people have celiac disease (CD), induced by gluten sensitivity. If left untreated, it causes small intestinal inflammation and villous atrophy, which can result in failure to thrive, anemia, osteoporosis, malabsorption, and even malignancy. The only treatment option available is a gluten-free diet (GFD). Few studies have looked at the role and perception of telehealth in relation to CD and selective nutrition both before and after the COVID-19 pandemic.

Our goal was to screen and investigate the research conducted both before and after the COVID-19 pandemic concerning the utilization of telehealth applications and solutions in CD and other GFD-dependent circumstances.

We employed a narrative review approach to explore articles that were published in scholarly journals or organizations between the years 2000 and 2024. Only English-language publications were included. PubMed and Google Scholar searches were mainly conducted using the following keywords: telemedicine, telehealth, telecare, eHealth, m-health, COVID-19, SARS-CoV-2, celiac disease, and gluten-free diet (GFD). Manual searches of the references in the acquired literature were also carried out, along with the authors' own personal contributions of their knowledge and proficiency in this field.

Only a few studies conducted prior to the COVID-19 outbreak examined the viewpoints and experiences of adult patients with CD with relation to in-person clinic visits, as well as other options such as telehealth. The majority of patients believed that phone consultations were appropriate and beneficial. Video conferencing and telemedicine became more popular during the COVID-19 pandemic, demonstrating the effectiveness of using these technologies for CD on a global basis. In recent years, urine assays for gluten identification have become accessible for use at home. These tests could be helpful for CD monitoring with telemedicine assistance.

The extended knowledge gathered from the COVID-19 pandemic is expected to complement pre-COVID-19 data supporting the usefulness of telemedicine even after the emergent pandemic, encouraging its wider adoption in standard clinical practice. The monitoring and follow-up of CD patients and other GFD-dependent conditions can greatly benefit from telemedicine.

Celiac disease (CD) is an autoimmune disease triggered by the ingestion of gluten in genetically predisposed individuals, affecting 1.4% of the world population. CD induces an inflammatory reaction that compromises small intestine villi, leading to nutrient malabsorption, and gastro and extraintestinal manifestations. Although other treatment approaches are being studied, adherence to a gluten-free diet (GFD) is the only effective intervention to date. Despite this, about 50% of patients experience persistent inflammation, often associated with unintentional gluten ingestion through contaminated food. There are regulations for labeling gluten-free foods which specify a limit of 20 mg/kg (20 ppm). The risks of gluten cross-contamination above that level are present throughout the whole food production chain, emphasizing the need for caution. This review explores studies that tested different procedures regarding the shared production of gluten-containing and gluten-free food, including the use of shared equipment and utensils. A literature review covering PubMed, Scielo, Web of Science, VHL and Scopus identified five relevant studies. The results indicate that shared environments and equipment may not significantly increase gluten cross-contamination if appropriate protocols are followed. Simultaneous cooking of gluten-containing and gluten-free pizzas in shared ovens has demonstrated a low risk of contamination. In general, shared kitchen utensils and equipment (spoon, ladle, colander, knife, fryer, toaster) in controlled experiments did not lead to significant contamination of samples. On the other hand, cooking gluten-free and gluten-containing pasta in shared water resulted in gluten levels above the established limit of 20 ppm. However, rinsing the pasta under running water for a few seconds was enough to reduce the gluten content of the samples to less than 20 ppm.

The extent and factors associated with risk of diagnostic delay in pediatric celiac disease (CD) are poorly understood.

To investigate the diagnostic delay of CD in childhood, and to assess factors associated with this delay.

Multicenter, retrospective, cross-sectional study (2010-2019) of pediatric (aged 0-18 years) patients with CD from 13 pediatric tertiary referral centers in Italy. Data were analyzed from January to June 2023.

The overall diagnostic delay (ie, the time lapse occurring from the first symptoms or clinical data indicative of CD and the definitive diagnosis), further split into preconsultation and postconsultation diagnostic delay, were described. Univariable and multivariable linear regression models for factors associated with diagnostic delay were fitted. Factors associated with extreme diagnostic delay (ie, 1.5 × 75th percentile) and misdiagnosis were assessed.

A total of 3171 patients with CD were included. The mean (SD) age was 6.2 (3.9) years; 2010 patients (63.4%) were female; and 10 patients (0.3%) were Asian, 41 (1.3%) were Northern African, and 3115 (98.3%) were White. The median (IQR) overall diagnostic delay was 5 (2-11) months, and preconsultation and postconsultation diagnostic delay were 2 (0-6) months and 1 (0-3) month, respectively. The median (IQR) extreme overall diagnostic delay (586 cases [18.5%]) was 11 (5-131) months, and the preconsultation and postconsultation delays were 6 (2-120) and 3 (1-131) months, respectively. Patients who had a first diagnosis when aged less than 3 years (650 patients [20.5%]) showed a shorter diagnostic delay, both overall (median [IQR], 4 [1-7] months for patients aged less than 3 years vs 5 [2-12] months for others) and postconsultation (median [IQR], 1 [0-2] month for patients aged less than 3 years vs 2 [0-4] months for others). A shorter delay was registered in male patients, both overall (median [IQR], 4 [1-10] months for male patients vs 5 [2-12] months for female patients) and preconsultation (median [IQR], 1 [0-6] month for male patients vs 2 [0-6] months for female patients). Family history of CD was associated with lower preconsultation delay (odds ratio [OR], 0.59; 95% CI, 0.47-0.74) and lower overall extreme diagnostic delay (OR, 0.75; 95% CI, 0.56-0.99). Neurological symptoms (78 patients [21.5%]; OR, 1.35; 95% CI, 1.03-1.78), gastroesophageal reflux (9 patients [28.1%]; OR, 1.87; 95% CI, 1.02-3.42), and failure to thrive (215 patients [22.6%]; OR, 1.62; 95% CI, 1.31-2.00) showed a more frequent extreme diagnostic delay. A previous misdiagnosis (124 patients [4.0%]) was more frequently associated with gastroesophageal reflux disease, diarrhea, bloating, abdominal pain, constipation, fatigue, osteopenia, and villous atrophy (Marsh 3 classification).

In this cross-sectional study of pediatric CD, the diagnostic delay was rather short. Some factors associated with risk for longer diagnostic delay and misdiagnosis emerged, and these should be addressed in future studies.

The relationship between Vitamin D levels and pediatric celiac disease (CD) remains controversial. In this study, we conducted a systematic review and meta-analysis to examine the relationship between Vitamin D and pediatric CD.

We screened relevant studies from PubMed, EMBASE, and Web of Science published in English from January 1, 2000, to August 1, 2023. The included studies were assessed according to the STROBE checklist. Heterogeneity was quantified by Cochran's Q test and the I2 statistic. Publication bias was estimated by Begg's test and Egger's test. Meta-regression was used to detect potential sources of heterogeneity.

A total of 26 studies were included in the meta-analysis. Nineteen articles compared 25(OH)D3 levels between CD patients and control groups, average 25-hydroxyvitamin D3 [25(OH)D3 or calcidiol], and 1,25-dihydroxyvitamin D3 [1,25(OH)2D3 or calcitriol] levels, as the main forms of Vitamin D, there was a significant difference in CD patients and healthy controls (weighted mean difference (WMD) = - 5.77, 95% confidence interval (CI) = [- 10.86, - 0.69] nmol/L). Meanwhile, eleven articles reported the numbers of patients and controls with Vitamin D deficiency, there was a significant difference in the incidence of 25(OH)D3 deficiency between CD patients and healthy controls (odds ratio 2.20, 95% CI= [1.19, 4.08]). Nine articles reported changes in 25(OH)D3 levels before and after administering a GFD in patients with CD, the result of this study revealed the increase of 25(OH)D3 levels in CD patients after a gluten-free diet (GFD) (WMD = - 6.74, 95% CI = [- 9.78, - 3.70] nmol/L).

Vitamin D levels in pediatric CD patients were lower than in healthy controls, and 25(OH)D3 deficiency was more prevalent in CD patients. We found that 25(OH)D3 levels were elevated in CD patients after GFD, which is consistent with previous research. Further well-designed, longitudinal, prospective cohort studies focusing on the role of Vitamin D in the pathogenesis of CD are therefore needed.

Over the last decade, autoimmune diseases (ADs) have undergone a significant increase because of genetic and/or environmental factors; therefore, their simple and fast diagnosis is of high importance. The conventional diagnostic techniques for ADs require tedious sample preparation, sophisticated instruments, a dedicated laboratory, and qualified personnel. For these reasons, biosensors could represent a useful alternative to these methods. Biosensors are considered to be promising tools that can be used in clinical analysis for an early diagnosis due to their high sensitivity, simplicity, low cost, possible miniaturization (POCT), and potential ability for real-time analysis. In this review, recently developed biosensors for the detection of autoimmune disease biomarkers are discussed. In the first part, we focus on the main AD biomarkers and the current methods of their detection. Then, we discuss the principles and different types of biosensors. Finally, we overview the characteristics of biosensors based on different bioreceptors reported in the literature.

The prevalence of coeliac disease doubled in Finland from 1980 to 2000.

To investigate whether this increase is continuing and if there are specific patient-related factors predicting the development of coeliac disease at a population level.

We elicited comprehensive health data in the nationwide Health 2000 and Health 2011 surveys. Serum samples were taken for the measurement of tissue transglutaminase antibodies (TGA); subjects who were seropositive were tested for endomysial antibodies (EmA). Coeliac disease was defined either as a reported diagnosis or as positive TGA and EmA. The surveys comprised, respectively, 6379 and 4056 individuals, forming representative samples for 2,946,057 and 2,079,438 Finnish adults. Altogether 3254 individuals participating in both surveys comprised a prospective follow-up cohort.

Prevalence of coeliac disease was 2.12% in 2000 and 2.40% in 2011 (p = 0.156). In the prospective cohort, 16 out of the 3254 (0.49%) subjects developed coeliac disease during follow-up from 2000 to 2011, with an annual incidence rate of 45 per 100,000 persons. Positive TGA without EmA (OR: 133, 95% CI: 30.3-584), TGA values in the upper normal range (51.1, 16.0-163), and after adjusting for TGA, previous autoimmune co-morbidity (8.39, 4.98-35.9) in 2000 increased the likelihood of subsequent coeliac disease.

The nationwide prevalence of coeliac disease kept on rising from 2.12% in 2000 to 2.40% in 2011 in Finland. Positive TGA without EmA, TGA titres in the upper normal range and a pre-existing autoimmune disease predisposed to coeliac disease during the 10-year follow-up.

A large number of patients with celiac disease (CD) remain undiagnosed because they do not fulfill the criteria for entry into the conventional diagnostic workflow. This study evaluated the clinical utility of anti-tissue transglutaminase IgA antibody lateral flow immunoassays (anti-tTG-IgA LFIA) in the undiagnosed-CD-based pediatric population and the impact of a gluten-free diet (GFD) on screening-detected CD. A total of 576 volunteers were tested for anti-tTG-IgA. Gluten consumption habits, CD related symptoms, and risk factors for CD development were evaluated. Volunteers testing positive for anti-tTG-IgA were referred to the conventional CD diagnostic workflow, and the impact of the GFD on health-related quality of life (HR-QoL) was measured. Among them, 13 had a positive anti-tTG-IgA LFIA test result: 11 had confirmed CD (1.91%), one refused confirmatory tests, and another is undergoing diagnosis. Regarding the CD prevalence, no significant differences were observed among risk (1.89%) and symptomatic (2.65%) groups and the entire tested population (1.55%). Rapid anti-tTG-IgA LFIAs could be of clinical utility in primary care for the early identification of children with CD unidentified by the conventional diagnostic workflow. It could potentially reduce the costs of undiagnosed CD, avoiding unnecessary referrals to gastroenterologists, reducing diagnosis delays and long-term problems, and improving patients' HR-QoL.

Sorghum (Sorghum bicolor), a grass native to Africa, is a popular alternative to barley for brewing beer. The importance of sorghum to beer brewing is increasing because it is a naturally gluten-free cereal, and climate change is expected to cause a reduction in the production of barley over the coming decades. However, there are challenges associated with the use of sorghum instead of barley in beer brewing. Here, we used proteomics and metabolomics to gain insights into the sorghum brewing process to advise processes for efficient beer production from sorghum. We found that during malting, sorghum synthesizes the amylases and proteases necessary for brewing. Proteomics revealed that mashing with sorghum malt required higher temperatures than barley malt for efficient protein solubilization. Both α- and β-amylase were considerably less abundant in sorghum wort than in barley wort, correlating with lower maltose concentrations in sorghum wort. However, metabolomics revealed higher glucose concentrations in sorghum wort than in barley wort, consistent with the presence of an abundant α-glucosidase detected by proteomics in sorghum malt. Our results indicate that sorghum can be a viable grain for industrial fermented beverage production, but that its use requires careful process optimization for efficient production of fermentable wort and high-quality beer.

Celiac disease is a global disease requiring genetic susceptibility and gluten exposure to trigger immune-mediated enteropathy. The effect of the degree of gluten-containing grain availability on celiac disease prevalence is unknown. Our objective was to compare country-based gluten availability to celiac prevalence using a systematic literature review. We searched MEDLINE, Embase, Cochrane, and Scopus until May 2021. We included population-based serum screening with confirmatory testing (second serological study or small intestine biopsy) and excluded specific, high-risk, or referral populations. We determined country-specific gluten availability using the United Nations food balance for wheat, barley, and rye. Human leukocyte antigen (HLA) frequencies were obtained from allelefrequencies.net. The primary outcome was association between gluten-containing grain availability and celiac disease prevalence. Generalized linear mixed models method with Poisson's link was used for analysis. We identified 5641 articles and included 120 studies on 427 146 subjects from 41 countries. Celiac disease prevalence was 0-3.1%, median 0.75% (interquartile range 0.35, 1.22). Median wheat supply was 246 g/capita/day (interquartile range 214.8, 360.7). The risk ratio (RR) for wheat availability on celiac disease was 1.002 (95% confidence interval [CI]: 1.0001, 1.004, P = 0.036). A protective association was seen with barley, RR 0.973 (95% CI: 0.956, 0.99, P = 0.003), and rye, RR 0.989 (95% CI: 0.982, 0.997, P = 0.006). The RR for gross domestic product on celiac disease prevalence was 1.009 (95% CI: 1.005, 1.014, P < 0.001). The RR for HLA-DQ2 was 0.982 (95% CI: 0.979, 0.986, P < 0.001), and that for HLA-DQ8 was 0.957 (95% CI: 0.950, 0.964, P < 0.001). In this geo-epidemiologic study, gluten-containing grain availability showed mixed associations with celiac disease prevalence.

Coeliac disease (CD) is a life-long food-related disorder with a global prevalence of approximately 1%. Patients with CD often experience reduced health-related quality of life that could improve with a strict adherence to a gluten-free diet (GFD).

To obtain visual analogue scale (VAS), time trade-off (TTO) and willingness-to-pay (WTP) values amongst patients with CD.

In 2020-2021, a cross-sectional online survey was conducted amongst 312 adult CD patients in Hungary. Patients completed the Gastrointestinal Symptom Rating Scale (GSRS) and evaluated their current health and three hypothetical health state vignettes defined based on dietary adherence using VAS, conventional 10-year TTO and WTP. Multivariate regressions were used to explore the effect of patients' demographic and clinical characteristics on utility and WTP values.

Mean VAS values for current health and 'CD with strict adherence to GFD', 'CD with loose adherence to GFD' and 'CD without GFD' hypothetical health states were 79.69 ± 18.52, 85.36 ± 16.18, 62.44 ± 19.91 and 36.69 ± 25.83, respectively. Corresponding mean TTO utilities were: 0.90 ± 0.19, 0.91 ± 0.20, 0.87 ± 0.23 and 0.76 ± 0.29. Mean annual WTP values for returning to full health were: €845 ± 1077, €648 ± 1002, €862 ± 1135 and €1251 ± 1496. Older age at diagnosis, male sex, more severe gastrointestinal symptoms (GSRS) and having comorbidities were associated with lower VAS and TTO or higher WTP values for current own health (p < 0.05).

This is the first study to report TTO utilities for CD health states. Strict adherence to the GFD may result in substantial health gains in symptomatic patients. Utilities and WTP results can be used to estimate benefits of GFD in cost-utility and cost-benefit analyses.

Children with celiac disease may face challenges in managing a gluten-free diet during their daily interactions and activities. The objective of this study was to compare how children with celiac disease manage their gluten-free diet and participate in food-related activities in Italy and Israel and to assess their quality of life. The previously validated Children's Activities Report (CD-Chart) and the Disease-specific Health-Related Quality of Life Questionnaire for Children with Celiac Disease (CDDUX) were administered in Italy to children aged 8-16 diagnosed with CD (n = 39). The results were compared to data that had been previously gathered from Israeli children with CD (n = 106). The CD-Chart demonstrated satisfactory internal reliability within each cultural group (Italy: α = 0.82; Israel: α = 0.76). Mann-Whitney U-tests indicated significant differences between the two groups. The Italian children exhibited a significantly higher preference for participating in the activities compared to the Israelis (U = 3283.50, p < 0.001). Nonetheless, the Italian children displayed a notable decrease in their level of involvement in the preparation required before engaging in different activities (U = 760.50, p < 0.001). Moreover, they exhibited significantly lower self-determination in this preparatory process compared to the Israeli children (U = 726.00, p < 0.001). Significant group differences were found between the CDDUX children's self-reports and parents' proxy reports in the Israeli group but not in the Italian group. The CD-Chart revealed both shared and distinct participation characteristics in daily food-related activities across different cultural contexts. By incorporating the CD-Chart and the CDDUX, healthcare professionals can emphasize crucial aspects of day-to-day health management and guide them in establishing suitable intervention objectives to enhance effective health self-management.

Ulcerative colitis (UC), Crohn's disease (CD), and celiac disease are prevalent intestinal inflammatory disorders with nonsatisfactory therapeutic interventions. Analyzing patient data-driven cohorts can highlight disease pathways and new targets for interventions. Long noncoding RNAs (lncRNAs) are attractive candidates, since they are readily targetable by RNA therapeutics, show relative cell-specific expression, and play key cellular functions. Uniformly analyzing gut mucosal transcriptomics from 696 subjects, we have highlighted lncRNA expression along the gastrointestinal (GI) tract, demonstrating that, in control samples, lncRNAs have a more location-specific expression in comparison with protein-coding genes. We defined dysregulation of lncRNAs in treatment-naive UC, CD, and celiac diseases using independent test and validation cohorts. Using the Predicting Response to Standardized Pediatric Colitis Therapy (PROTECT) inception UC cohort, we defined and prioritized lncRNA linked with UC severity and prospective outcomes, and we highlighted lncRNAs linked with gut microbes previously implicated in mucosal homeostasis. HNF1A-AS1 lncRNA was reduced in all 3 conditions and was further reduced in more severe UC form. Similarly, the reduction of HNF1A-AS1 ortholog in mice gut epithelia showed higher sensitivity to dextran sodium sulfate-induced colitis, which was coupled with alteration in the gut microbial community. These analyses highlight prioritized dysregulated lncRNAs that can guide future preclinical studies for testing them as potential targets.

Celiac disease (CD) in adults with type 1 diabetes has been associated with increased cardiovascular risk and the earlier occurrence of diabetes-associated complications. In the Search for Diabetes in Youth study, we aimed to assess the frequency of CD and the potential for undiagnosed CD among youth with childhood onset type 1 diabetes. In addition, we assessed the burden of cardiovascular risk factors and diabetes-associated complications in youth with type 1 diabetes by CD status and IgA tissue transglutaminase autoantibody (tTGA) levels.

2,444 youths with type 1 diabetes completed a CD questionnaire and underwent tTGA testing. Integrating the celiac disease questionnaire and tTGA results for this cross-sectional analysis, participants were categorized as follows: (1) reported CD; (2) seropositive for CD (no reported CD and seropositive tTGA); and (3) type 1 diabetes only (comparison group: no reported CD and seronegative tTGA). Subanalyses were performed on those with no reported CD and tTGA ≥10x ULN, designated potentially undiagnosed CD. Cardiovascular risk factors and diabetes-associated complications were evaluated by CD status and tTGA levels utilizing a Poisson model to estimate relative risk.

Reported CD in youths with type 1 diabetes was 7%. Seropositivity for tTGA with no reported CD was present in 4%, and 1.2% had potentially undiagnosed CD. Youths with potentially undiagnosed CD had a 2.69x higher risk of diabetic retinopathy than comparison group. In addition, CD with tTGA <0.05 (controlled CD) was associated with lower HbA1c.

Undiagnosed CD is likely present in youths with type 1 diabetes and potentially undiagnosed CD is associated with a higher risk of diabetic retinopathy. These findings indicate the importance of routine screening for CD in type 1 diabetes in youths.

In return for their nutritional properties and broad availability, cereal crops have been associated with different alimentary disorders and symptoms, with the majority of the responsibility being attributed to gluten. Therefore, the research of gluten-related literature data continues to be produced at ever-growing rates, driven in part by the recent exploratory studies that link gluten to non-traditional diseases and the popularity of gluten-free diets, making it increasingly difficult to access and analyse practical and structured information. In this sense, the accelerated discovery of novel advances in diagnosis and treatment, as well as exploratory studies, produce a favourable scenario for disinformation and misinformation.

Aligned with, the European Union strategy "Delivering on EU Food Safety and Nutrition in 2050" which emphasizes the inextricable links between imbalanced diets, the increased exposure to unreliable sources of information and misleading information, and the increased dependency on reliable sources of information; this paper presents GlutKNOIS, a public and interactive literature-based database that reconstructs and represents the experimental biomedical knowledge extracted from the gluten-related literature. The developed platform includes different external database knowledge, bibliometrics statistics and social media discussion to propose a novel and enhanced way to search, visualise and analyse potential biomedical and health-related interactions in relation to the gluten domain.

For this purpose, the presented study applies a semi-supervised curation workflow that combines natural language processing techniques, machine learning algorithms, ontology-based normalization and integration approaches, named entity recognition methods, and graph knowledge reconstruction methodologies to process, classify, represent and analyse the experimental findings contained in the literature, which is also complemented by data from the social discussion.

and Conclusions: In this sense, 5,814 documents were manually annotated and 7,424 were fully automatically processed to reconstruct the first online gluten-related knowledge database of evidenced health-related interactions that produce health or metabolic changes based on the literature. In addition, the automatic processing of the literature combined with the knowledge representation methodologies proposed has the potential to assist in the revision and analysis of years of gluten research. The reconstructed knowledge base is public and accessible at https://sing-group.org/glutknois/.

Celiac disease (CD) is an autoimmune disease leading to gastrointestinal symptoms and mineral deficiencies. The pathogenetic mechanisms, besides the clear HLA association, are elusive. Among environmental factors infections have been proposed. Covid-19 infection results in a systemic inflammatory response that often also involves the gastrointestinal tract. The aim of the present study was to investigate whether Covid-19 infection could increase the risk for CD.

All patients, both children and adults, in the county Skåne (1.4 million citizens) in southern Sweden with newly diagnosed biopsy- or serology-verified CD or a positive tissue transglutaminase antibody test (tTG-ab) during 2016-2021 were identified from registries at the Departments of Pathology and Immunology, respectively. Patients with a positive Covid-19 PCR or antigen test in 2020 and 2021 were identified from the Public Health Agency of Sweden.

During the Covid-19 pandemic (March 2020 - December 2021), there were 201 050 cases of Covid-19 and 568 patients with biopsy- or serology-verified CD or a first-time positive tTG-ab tests, of which 35 patients had been infected with Covid-19 before CD. The incidence of verified CD and tTG-ab positivity was lower in comparison to before the pandemic (May 2018 - February 2020; 22.5 vs. 25.5 cases per 100 000 person-years, respectively, incidence rate difference (IRD) -3.0, 95% CI -5.7 - -0.3, p = 0.028). The incidence of verified CD and tTG-ab positivity in patients with and without prior Covid-19 infection was 21.1 and 22.4 cases per 100 000 person-years, respectively (IRD - 1.3, 95% CI -8.5-5.9, p = 0.75).

Our results indicate that Covid-19 is not a risk factor for CD development. While gastrointestinal infections seem to be an important part of the CD pathogenesis, respiratory infections probably are of less relevance.

Celiac disease (CD) is an immune-mediated enteropathy caused by a permanent sensitivity to gluten in genetically susceptible individuals. In rare cases, CD may occur with a severe potential life-threatening manifestation known as a celiac crisis (CC). This may be a consequence of a delayed diagnosis and expose patients to possible fatal complications. We report the case of a 22-month-old child admitted to our hospital for a CC characterized by weight loss, vomiting, and diarrhea associated with a malnutrition state. Early identification of symptoms of CC is essential to provide a prompt diagnosis and management.

The description of the clinical presentation of celiac disease (CeD) has usually come from studies at referral centers. Data about CeD presentation in the community are sparse.

We aim to describe the clinical presentation of patients with biopsy-proven CeD at a community-based adult gastroenterology practice and compare it to a referral center.

We performed a retrospective study of two cohorts of patients diagnosed with CeD between 2000-2007 (n = 117) and 2013-2016 (n = 91) in a community practice, and a third cohort (n = 188) diagnosed between 2000 and 2007 in a tertiary referral center. The clinical presentation, body mass index, tissue-transglutaminase levels, DEXA scan, vitamin D levels, and vaccine recommendations were assessed.

Celiac disease presentation changed over time in the two community cohorts. Recently, fewer patients presented with diarrhea and anemia, but constipation and neurologic symptoms were more common. The most recent cohort had a higher proportion of patients who were overweight or obese than the first cohort. However, the body mass index in both community cohorts was higher than in the tertiary referral center. The frequency of osteopenia and osteoporosis was high in both community cohorts. The tertiary referral center patients were younger, presented with a higher proportion of diarrhea and a lower body mass index.

The clinical presentation of CeD differs between the community setting and a tertiary referral center. Patients with CeD presenting to the community setting tended to be older, overweight, and to have a high proportion of mineral bone disease.

Glycoprotein 2 (GP2) is an autoantigen in Crohn's (CD) and coeliac disease (CeD). We assessed GP2-isoform (GP2_1-4)-expression in intestinal biopsies of paediatric patients with CD, CeD, ulcerative colitis (UC), and healthy children (HC). Transcription of GP2_1-4 was elevated in proximal small intestine in CeD and CD patients (only GP2_2/4) compared to jejunum (CeD/CD) and large bowel (CD). CeD patients demonstrated higher duodenal GP2_2/4-mRNA levels compared to HC/UC patients whereas CD patients showed higher GP2₄-mRNA levels compared to UC patients. Duodenal synthesis of only small GP2 isoforms (GP2_3/4) was demonstrated in epithelial cells in patients/HC and in Brunner glands (also large isoforms) with a more frequent apical location in CD/CeD patients. All four GP2 isoforms interacted with gliadin and phosphopeptidomannan. Gliadin digestion improved binding to GP2 isoforms. GP2_1-4 binding to CeD/CD-related antigens, elevated duodenal GP2_1-4-mRNA transcription, and GP2-protein secretion in Brunner glands of CeD/CD patients suggest an autoimmune CeD/CD link.

The pattern of practice regarding the diagnosis, dietary counselling and follow-up of patients with celiac disease (CeD) varies between practice to practice.

A web-based questionnaire based on review of literature, group discussions and expert group meetings was developed to understand the practice of CeD in India. The questionnaire was administered through social media (WhatsApp) to 18 Indian celiac support groups comprising 2980 patients with CeD.

Overall, 970 (32.5%) patients responded to the questionnaire (median age: 21 years; females 63.9%). While 679 (71.1%) patients were diagnosed based on a combination of serology and biopsy, 214 (22.4%) were diagnosed based on serology alone. After diagnosis, 875 (91%) patients were counselled initially by physician and only 585 (61%) were referred to a dietician for dietary counselling. In a majority of cases, the time spent by doctors and dietitians during first counselling was between 10 and 20 minutes only. After first counselling, 191 (20%) and 355 (37.3%) patients did not re-visit the physician and the dietitian, respectively. Among those who followed up, structured follow-up was conducted in only 515 (53.8%) patients. Overall, 232 (24.3%) patients were self-monitoring their serological parameters, while 495 (51.8%) patients did not receive a formal assessment of dietary adherence during follow-up.

The practice of diagnosis, dietary counselling and follow-up of patients with CeD in India is not as per standard guidelines. Most of the patients are not referred to a dietitian. There is a need for reinforcement of guidelines for proper care and management of patients with CeD.

Antibiotic use is increasing worldwide. However, the use of antibiotics is clearly associated with changes in gut microbiome composition and function, and perturbations have been identified as potential environmental risk factors for chronic inflammatory disorders of the gastrointestinal tract. In this Review, we examine the association between the use of antibiotics and the onset and development of both type 1 and type 2 diabetes, inflammatory bowel disease, including ulcerative colitis and Crohn's disease, as well as coeliac disease and eosinophilic oesophagitis. We discuss the key findings of epidemiological studies, provide mechanistic insights into the pathways by which the gut microbiota might contribute to these diseases, and assess clinical trials investigating the effects of antibiotics. Such studies indicate that antibiotic exposures, varying in type, timing and dosage, could explain differences in disease risk. There seems to be a critical window in early life in which perturbation of the microbiome has a substantial effect on disease development. Identifying the antibiotic-perturbed gut microbiota as a factor that contributes to the pathophysiology of these inflammatory disorders might stimulate new approaches to prevention, diagnosis and treatment.

This guideline presents an update to the 2013 American College of Gastroenterology Guideline on the Diagnosis and Management of Celiac Disease with updated recommendations for the evaluation and management of patients with celiac disease (CD). CD is defined as a permanent immune-mediated response to gluten present in wheat, barley, and rye. CD has a wide spectrum of clinical manifestations that resemble a multisystemic disorder rather than an isolated intestinal disease, and is characterized by small bowel injury and the presence of specific antibodies. Detection of CD-specific antibodies (e.g., tissue transglutaminase) in the serum is very helpful for the initial screening of patients with suspicion of CD. Intestinal biopsy is required in most patients to confirm the diagnosis. A nonbiopsy strategy for the diagnosis of CD in selected children is suggested and discussed in detail. Current treatment for CD requires strict adherence to a gluten-free diet (GFD) and lifelong medical follow-up. Most patients have excellent clinical response to a GFD. Nonresponsive CD is defined by persistent or recurrent symptoms despite being on a GFD. These patients require a systematic workup to rule out specific conditions that may cause persistent or recurrent symptoms, especially unintentional gluten contamination. Refractory CD is a rare cause of nonresponsive CD often associated with poor prognosis.

The effects of early feeding practices on the risk of coeliac disease (CD) remain debated.

To update evidence on these practices on the risk of CD and/or CD-related autoimmunity (CDA), defined as anti-transglutaminase or anti-endomysial antibody positivity METHODS: We searched MEDLINE, EMBASE and the Cochrane Library to May 2022 for randomised controlled trials (RCTs) and observational studies.

We included 36 publications (30 studies). In the population at genetic risk of developing CD (HLA DQ2/DQ8-positive), exclusive or any breastfeeding and longer breastfeeding duration did not reduce the risk of developing CD/CDA during childhood. While a meta-analysis of four case-control studies showed a decreased risk for CD when gluten was introduced during breastfeeding, this was not shown in RCTs and cohort studies. Age at gluten introduction was not associated with cumulative CD/CDA risk, although two RCTs suggested that earlier gluten introduction was associated with earlier CDA appearance. Evidence from six observational studies suggests that consumption of a higher amount of gluten at weaning and/or thereafter may increase CD risk. There is insufficient evidence to determine the amount of gluten associated with an increased CD/CDA risk. Regarding whether infant feeding practices modulate the risk conferred by different HLA genotypes results were inconsistent.

For the population at genetic risk of CD, breastfeeding and age at gluten introduction have no effect on its cumulative incidence during childhood. There is some evidence for an effect of the amount of gluten consumed at weaning and/or thereafter on CD/CDA risk.

Celiac disease (CeD) is associated with type 1 diabetes mellitus (T1DM), and both have the same genetic background. Most patients with T1DM who develop CeD are either asymptomatic or have mild CeD-related gastrointestinal symptoms. Therefore, children affected by T1DM should undergo screening for asymptomatic CeD. The aim of this review is to highlight the influence of a gluten-free diet (GFD) on glycemic control, growth rate, microvascular complications, and quality of life in patients with T1DM and CeD. PubMed, Google Scholar, Web of Science, and Cochrane Central databases were searched. Reports reviewed were those published from 1969 to 2022 that focused on the interplay of T1DM and CeD and examined the effect of diet on glycemic control, growth rate, and quality of life. The most challenging aspect for a child with T1DM and CeD is that most GFD foods have a high glycemic index, while low glycemic index foods are recommended for T1DM. Interestingly, dietary therapy for CeD could improve the elevated HbA1c levels. Avoiding gluten added to a diabetic dietary regimen in T1DM patients might impose practical limitations and lead to important restrictions in the lifestyle of a young patient. Consequently, non-adherence to GFD in patients with T1DM and CeD is common. GFD in patients with T1DM and CeD seems to lower the incidence of micro- and macrovascular complications, but this requires further investigation. It seems that adherence to GFD in young patients with T1DM and CeD leads to regular growth and a stable body mass index without any negative effect on HbA1c or insulin requirements. Furthermore, the lipid profile and quality of life seem to have improved with the introduction of GFD.
