Once thought to be uncommon, celiac disease has now become a common disease globally. While avoidance of the gluten-containing diet is the only effective treatment so far, many new targets are being explored for the development of new drugs for its treatment. The endpoints of therapy include not only reversal of symptoms, normalization of immunological abnormalities and healing of mucosa, but also maintenance of remission of the disease by strict adherence of the gluten-free diet (GFD). There is no single gold standard test for the diagnosis of celiac disease and the diagnosis is based on the presence of a combination of characteristics including the presence of a celiac-specific antibody (anti-tissue transglutaminase antibody, anti-endomysial antibody or anti-deamidated gliadin peptide antibody) and demonstration of villous abnormalities. While the demonstration of enteropathy is an important criterion for a definite diagnosis of celiac disease, it requires endoscopic examination which is perceived as an invasive procedure. The capability of prediction of enteropathy by the presence of the high titer of anti-tissue transglutaminase antibody led to an option of making a diagnosis even without obtaining mucosal biopsies. While present day diagnostic tests are great, they, however, have certain limitations. Therefore, there is a need for biomarkers for screening of patients, prediction of enteropathy, and monitoring of patients for adherence of the gluten-free diet. Efforts are now being made to explore various biomarkers which reflect different changes that occur in the intestinal mucosa using modern day tools including transcriptomics, proteomics, and metabolomics. In the present review, we have discussed comprehensively the pros and cons of available biomarkers and also summarized the current status of emerging biomarkers for the screening, diagnosis, and monitoring of celiac disease.

Background: Few studies exist examining the frequency of primary headache in children with celiac disease and the impact of a gluten-free diet on primary headache symptomology. This study explores characteristics and frequency of headaches in children with celiac disease and response to gluten-free diet at a single institution. Methods: Medical records were reviewed for children with celiac disease confirmed by the presence of elevated tissue transglutaminase IgA levels and histologic changes consistent with the diagnosis of celiac disease on small bowel biopsy. Eligible participants were contacted via letter for participation in a phone survey regarding headaches. Phone interviews were conducted 2 weeks after notification and lasted approximately 10 minutes. Headaches were classified according to ICHD-3 criteria. Results: 247 eligible patients or their families were contacted. A total of 132 (53.44%) agreed to participate. One participant was excluded due to insufficient information provided. Overall, 51 of 131 participants had recurrent headache defined as at least 1 episode per month (39%, 95% confidence interval [CI]: 31%-47%) and 33 had migraine with or without aura (25%, 95% CI: 18%-33%). Twenty-eight had frequent tension-type headache (22%, 95% CI: 15%-29%). Thirty-two participants noted headaches before a confirmed diagnosis of celiac disease. Twenty-two of 32 participants (68.75%) noticed decreased headache frequency or intensity, or both, after starting the gluten-free diet. Conclusion: This study suggests that at least one-third of children and adolescents with celiac disease have recurrent headaches at the time of diagnosis. A gluten-free diet led to improved headache symptomology in a significant number of these patients.

Objectives and study: To compare the values of gluten-related immunogenic peptides (GIP) in stool and anti-tissue transglutaminase IgA antibodies (anti-tTG IgA) in blood in children newly diagnosed with coeliac disease (CD). Methods: All children (2–15 y) newly diagnosed with CD between May 2018 and May 2020 at our clinic who complied with the inclusion criteria were invited to join the prospective study. During workup for CD, a stool sample to measure GIP was taken together with a blood sample to measure anti-tTG IgA. All newly diagnosed children were invited 4 months later for a check-up. Children and their caregivers were asked about known non-compliance with the gluten-free diet (GFD), a blood sample was taken to measure the anti-tTG IgA, and a stool sample was collected to measure GIP. Blood was evaluated for anti-tTG IgA by ELISA, and the stool was tested by quantitative Sandwich ELISA designed to detect and quantify GIP using the G12 antibody. Values of GIP and anti-tTG IgA were compared in terms of their relation to the upper limit of normal (ULN) of the particular method. Results: 29 children (18 girls) were enrolled in the study. The values of GIP in stool at the time of diagnosis were above the ULN (0.15 µg/g) in all children. Average 4.21, median 3.29, standard deviation (SD) 3.7. After the four months, all but three (89.7%) had values of GIP in the reference range. Average 0.29, median 0.12, SD 0.73. Similarly, anti-tTG IgA values were above the ULN (9.9 U/mL) at the time of diagnosis in all children. Average 164, median 195, SD 49. Although the anti-tTG IgA levels were lower at check-up in all but one child, only 10 (34.5%) showed values within the normal range, with an average of 27.9, median 12.0, and SD 38.9. All children declared strict adherence to GFD. Discussion: Using the GIP concentration in stool, adherence to GFD in our cohort of children is very good, better than that described in literature. Conclusion: Measuring GIP in stool could prove a more sensitive indicator of adherence to GFD in the early months after the diagnosis of CD when anti-tTG IgA are still elevated above the ULN due to their well-described gradual decrease after GFD initiation.

Abstract Celiac disease (CD) is a malabsorptive disorder wherein the proximal small bowel mucosa is damaged as a result of dietary exposure to gluten. Children with intractable diarrhea and failure to thrive are diagnosed with relative ease. Diagnosis can however be challenging and is often delayed when children present with ‘difficult to treat anemia’, without overt gastrointestinal manifestations. The case records of 77 patients with CD were scrutinized retrospectively. Diagnosis was established with serology (tissue transglutaminase-IgA assay) in 46 (59.7%), serology along with small bowel mucosal biopsy in 23 (29.9%) and with biopsy alone in the remaining 8 (10.4%). All children belonged to the predominantly wheat consuming northern Indian states. The mean age at presentation was 99.1±34.8 months (median: 102, range: 22–168). Males outnumbered females in a ratio of 1.96:1. The mean duration of symptoms was 41±31.2 months (median: 36, range: 1–132). The overwhelming majority, i.e., 75 (97.4%) children had anemia (Hemoglobin <11 g/dL). Mean hemoglobin (Hb) was 7.0±2.2 g/dL (median: 7.2, range: 2.3–12.5). 52 (67.5%) had received iron supplements for sufficient lengths, without benefit. The red cell morphology was microcytic hypochromic in 37 (48%) and dimorphic in 33 (42.9%). A history of diarrhea was not forthcoming in 32 (41.6%) cases. 59 (76.6%) were malnourished, with a weight less than 80 % of expected for the age and 30 (39 %) were stunted, with a height falling below the 90% of expected. Two children had skin bleeds secondary to coagulopathy, due to Vitamin K malabsorption. In another 2, recurrent anemia was attributed to pulmonary hemosiderosis; further investigations for secondary causes unearthed CD. All children were initiated on an austere gluten free diet, along with iron and folic acid supplements for the initial 6–9 months. Mean duration of follow was 17.7±20.9 months. Improvement was perceptible within days of initiating gluten free diet. Of the 38 (49.4%) children who had a follow up of a year or longer, the mean Hb at the last visit had risen to 12.9±1.2 g/dL. Conclusions: Hematologists need to be aware of the mono-symptomatic presentation of CD with anemia. The typical period of presentation of CD is described to be between 6 mo and 2 yr of age. Prolonged duration of symptoms and a diagnosis at a relatively older age is striking in the index study. In a suggestive clinical background, identification of CD with serodiagnosis alone, without resorting to small bowel biopsy is increasingly gaining acceptance, as the specificity of newer serological assays is 95–98%. This is particularly true in tropical countries, where some degree of flattening of villi may be attributed to malnutrition and or infections, such as rotavirus enteritis, Giardia lamblia, or tropical sprue. A biopsy may be misleading in such cases. Heightened awareness is essential to identify CD at an early age, especially, in children in whom anemia is the dominant manifestation. The benefits of gluten free diet are apparent with the rise in hemoglobin and the improvement in growth parameters are gratifying both for physicians and the caretakers.

Gluten-free diet is the current treatment of celiac disease. We decided to verify the occurrence of histological and serological modification and/or clinical manifestations during a gradual and progressive introduction of gliadin in the diet and if it may induce a tolerance to food, as it occurs in allergic patients. We studied the case of a celiac woman with complete clinical and histological remittance after 10 years of gluten free diet. She took increasing daily doses of gliadin, reaching the final dose of 9 g of gliadin (15 g of gluten) in 6 months. Then she started a free dietary regimen. During the 15-month follow-up period esophago-gastro-duodenoscopy showed normal Kerckring folds and villi. Anti-gliadin, anti-endomysium and anti-tissue-transglutaminase antibodies, as well as the haematological and biochemical parameters remained normal. Our results represent a new approach in the research concerning celiac disease, and could provide a future line of study for its management.

AbstractA very limited amount of data are available regarding the follow-up of celiac disease (CD) treatment in Iran. The aim of this study is to investigate antitissue transglutaminase (atTG) normalization interval and the associated factors in CD patients. This retrospective study included CD patients enrolled in Children's Medical Center, Tehran University of Medical Sciences. The initial atTG titer and histological evaluation (with Marsh grade ≥2) were recorded. The atTG titer was assessed in each follow-up until the time of normalization where children were strictly on gluten-free diet. The age at the time of diagnosis, gender, Marsh grade at the time of diagnosis, other comorbidities, and family history of CD patients were recorded to determine the association of these factors with antibody normalization interval. In total, 71 patients were recruited in the study of which 34 (47.89%) subjects had atTG level below 20 U/mL at the average interval of 31.36 ( ±  2.89) months (95% confidence interval: 25.7–37.02). There was no significant difference between the antibody normalization interval and different age ranges and Marsh grade. Cox regression demonstrated that gender, age ranges, Marsh grade, positive family history of CD, and the presence of comorbidities did not significantly predict longer antibody normalization interval.

Children with type 1 diabetes (T1D) are at increased risk of celiac disease (CD). The replacement of insulin in T1D, and the exclusion of gluten in CD, are lifelong, burdensome treatments. Compliance to a gluten-free diet (GFD) in children with CD is reported to be high, while compliance in children with both diseases has scarcely been studied. To examine compliance to a GFD in children with both T1D and CD, we analyzed tissue transglutaminase IgA-antibodies (tTGA). Moreover, associations between compliance and age, sex, glycemic control, ketoacidosis (DKA), body mass index (BMI), and time of CD diagnosis were investigated. Of the 743 children diagnosed with T1D in southern Sweden between 2005 and 2012, 9% were also diagnosed with CD. Of these, 68% showed good compliance to a GFD, 18% showed intermediate compliance, and 14% were classified as non-compliant. Higher age, poorer HbA1c, and more DKAs were significantly (p < 0.05) associated with poorer compliance. In conclusion, we found that compliance to a GFD in children with T1D and CD is likely be lower than in children with CD only. Our results indicate that children with both T1D and CD could need intensified dietary support and that older children and children with poor metabolic control are especially vulnerable subgroups.

The purpose of the study: analysis of medical and social problems and factors affecting the availability and compliance of a gluten-free diet, based on a survey of parents of children with celiac disease living in southern Russia. Purpose of the Study: Analysis of the medical and social problems and factors affecting the availability and adherence to the gluten-free diet based on the results of the questioning survey of the parents of children with celiac disease that are residents of the south of Russia. Children Characteristics and Study Methods. The study include 200 families that bring up the children with the celiac disease at the ages from 10 months to 18 years. The patients included 116 (58%) girls and 84 (42%) boys. The medical and social issues were studied using the developed questionnaire consisting of the open questions and intended as self-administered by the patient parents. Results. 87% of the families noted the significant difficulties in adhering to the diet, 75% were forced to refuse to travel with children, 56% of the surveyed were unable to visit the public spaces, restaurants, and 90% indicated the impossibility and difficulties in purchase of the gluten-free products. The strict adherence to the diet at school age is much worse. The main reasons for the deliberate non- adherence to the gluten-free diet are the high cost of food, lack of funds to purchase it. The patient families spend RUB 8,000– 9,000 per month in average to purchase the gluten-free products. There is a great demand of patients for the imported products with the relevant quality marks. The psychological symptoms were noted in the patients with celiac disease in response to the introduction of the gluten-free diet, manifested by the depression, aggression, irritability, high level of the anxiety. Conclusion. The main difficulties faced by the families that bring up the children and adolescents with the celiac disease include the social and psychological maladjustment of the patients, reduced finances, search and purchase of the high-quality gluten-free products and the necessity to adapt the child and family members to the dietary habits.

Background. Celiac disease (gluten enteropathy) is relatively rare disease. However, such patients have higher risk of skin pathology than general the population, and their therapy efficacy is limited by the use of gluten-free diet. Therefore, screening of dermatologic patients on celiac disease may be relevant. Objective. Our aim was to study the prevalence of celiac disease among children with skin pathology. Methods. The study included children hospitalized in dermatology department. Screening for celiac disease included detection in blood serum of antibodies (IgA, IgG, IgM) to tissue transglutaminase via rapid tests. In case of positive result of rapid test, we have repeated the estimation of antibodies (IgA, IgG) to tissue transglutaminase via immunochemiluminescent method with ImmunoCAP technology or via enzyme immunoassay. In case of positive serological test, we have performed HLA typing to determine haplotypes of DQ2 and DQ8, as well as esophagogastroduodenojejunoscopy (EGDJS) with biopsy of the duodenal and jejunal mucosa for further histological verification of the diagnosis. Results. We examined 1,000 children with various dermatologic pathologies. Rapid tests showed positive result in 21 patients (2.1%; 95% C11.3-3.2%). The presence of antibodies to tissue transglutaminase was confirmed via additional serological examination in all cases. HLA-haplotypes DQ2/8 were revealed in all patients with positive rapid test results. Typical form of gluten enteropathy was confirmed in 18/21 patients (86%) according to a histological study, thus, estimated prevalence of celiac disease is 1.8% (95% C11.1-2.8%). Conclusion. The prevalence of celiac disease remains underestimated among children with skin diseases. More studies are needed on the diagnostic features of rapid tests on tissue transglutaminase, as well as the benefits of screening for celiac disease to achieve patient-relevant clinical outcomes of skin pathology with wider gluten-free diet.
