AbstractBackground and objectivesAccording to recent guidelines, a diagnosis of celiac disease (CD) can be made without a biopsy, especially in children. There are no enough studies despite high prevalence and differences in genetic, race, and cultures. Therefore, we examined the correlation between tissue transglutaminase (TTG) and duodenal biopsy changes in our region because we are identical and different from others in culture, environment, and habits, and the correlation is same as that in different regions.MethodsA retrospective cohort study at the Ministry of National Guard Health Affaires (NGHA) health care facilities that are distributed throughout kingdom of Saudi Arabia from April 19, 2015, till March 29, 2018. This study used the BESTCARE system that includes data from all NGHA facilities; data from 513 patients with CD were collected. All patients diagnosed with celiac disease aged 15 years or more, confirmed by improvement on gluten-free diet (GFD), and were not on GFD before endoscopy or serology test or both of them were included in the study, and the TTG IgA level was measured at the same time or within 2–3 months of biopsy date. The exclusion criteria were negative duodenal biopsy, which is less than 2; patients with negative biopsy and negative serology; patients who were on GFD before testing, and any patients known to have immunity diseases or illness causing mucosal changes. The TTG IgA level was measured in IU/ mL and was labeled as negative (<20 IU/mL) and positive (≥ 20 IU/mL) based on the cutoff value. However, Intestinal biopsy findings were identified as Marsh classification groups.ResultsOne hundred thirty-four patients who met the inclusion criteria were included in the study. Median age of our sample was 24 years (16–37 years). Among these, 99 (73.88%) were female patients, whereas male patients were only 35 (26.12%). Histopathologic investigation of intestinal biopsy were Marsh 0 group was 16 cases (11.9%), Marsh 1 group was 8 cases (6%), Marsh 2 group was 4 cases (3%), Marsh 3a group was 32 cases (23.9%), Marsh 3b group was 64 cases (47.8%), and Marsh 3c group was 10 cases (7.5%). The TTG IgA antibody serology groups were <20 IU/mL in 13 cases (9.7%) and ≥20 IU/mL in 121 cases (90.3%). Among all patients with CD who had negative biopsy (Marsh 0 group), 16 (100%) of them had positive TTG IgA antibody. However, among patients with Marsh 1 group biopsy, 5 (62.5%) cases had negative TTG IgA antibody compared with 3 (37.5%) positive cases. Of the four cases (100%) with Marsh 2 group, all of them had positive TTG IgA antibody. However, in Marsh 3a group biopsy, 3 (9.4%) cases had negative TTG IgA antibody compared with 29 (90.6%) cases with positive TTG IgA antibody. Furthermore, among the patients with Marsh 3b group biopsy, 5 (7.8%) had negative antibody and 59 (92.2%) had positive serology. Of all biopsies of Marsh 3c group, 10 (100 %) had positive TTG IgA antibody.ConclusionsIn perspective of high prevalence of CD in KSA, even more than western countries, we can pretend that positive TTG antibody tests can be applied for the diagnosis of CD without biopsy, particularly in symptomatic patients along with high titer, that is, 5–10 times the upper limit of normal (ULN). However, to validate it further, we need larger prospective studies in which duodenal biopsies should be taken according to recommended protocol and should be interpreted by experienced pathologist. Furthermore, biopsy is still needed in patients who do not show clinical improvement on a gluten-free diet and in cases with mildly or moderately elevated TTG IgA.

Celiac disease is a small bowel disorder characterized by flattened villi and crypt hyperplasia, often with malabsorption. Improvement occurs with a gluten-free diet. Sensitive and specific assays (eg, immunoglobulin A antibodies to tissue transglutaminase [tTG]) that can be quantified appear to be valuable tools for population screening studies. In addition, their use is expanding widely in the clinical practice arena, being employed as a method of case finding. In this evaluation, clinical use of a commercially available test kit was explored. Of 1330 samples submitted to our hospital laboratory by physicians in British Columbia, Alberta and the Yukon Territory (from 1999 to 2003, inclusive), 96 patients (7%) had increased values (normal range greater than 20 units) and markedly increased levels greater than 100 units were detected in 36 patients (3%). Of these, 14 patients (almost 40%) were referred to gastroenterologists in our hospital and all 14 had small intestinal biopsies. Of these, three patients (more than 20%) did not have celiac disease. Two had normal small bowel biopsies and one had unclassified sprue or 'sprue-like' intestinal disease that failed to respond to a gluten-free diet. The other 11 had biopsy-defined celiac disease. While the tTG assay may be a useful predictor of celiac disease, small intestinal biopsy is still required to confirm the diagnosis. In clinical practice, even strongly positive tTG results are not specific in individual patients, do not necessarily correlate with the degree of severity of biopsy change and, as a result, are also unlikely to be useful for monitoring diet compliance.

Celiac disease (CD) is an autoimmune disorder characterized by an immune response to gluten peptides in wheat, barley, and rye. The diagnosis of celiac disease is confirmed by three important characteristics: consistent symptoms, positive celiac-specific serology, and small intestinal biopsy findings of inflammation, crypt hyperplasia, and villous atrophy. CD may present with overt gastrointestinal symptoms, including diarrhea (or constipation), weight loss, and abdominal bloating and discomfort, or covertly with micronutrient deficiencies such as iron deficiency with anemia. A gluten-free diet (GFD) remains the mainstay of treatment. The aim of this review is to highlight the pathogenesis of CD, concepts and challenges associated with a GFD, and nutritional management of CD applicable in clinical practice to internists, gastroenterologists, and dietitians. Patients should be referred to an expert celiac dietitian for education on adherence to a GFD to address gluten contamination in the diet, the psychosocial implications of following a GFD, and macro- and micronutrient disequilibria arising from celiac disease and the GFD. Several novel therapeutics are on the horizon in various stages of development, including glutenases, antigliadin antibodies, tight junction regulators, modulation of the immune response to gliadin, and efforts to engineer less toxic gluten-containing foodstuffs. This review contains 3 figures, 5 tables, and 61 references. Key words: celiac disease, genetic engineering, food engineering, gluten, glutenases, gluten-free diet, oats, IgY, nutrition, tight junction regulators, wheat

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.

ABSTRACT BACKGROUND: Familial Mediterranean fever and celiac disease share some common clinical features such as abdominal pain, diarrhea, arthralgia and arthritis. Also, both of the diseases are associated with many inflammatory and autoimmune diseases. Previous studies have shown the association between familial Mediterranean fever (FMF) and different clinical conditions. OBJECTIVE: We aimed to investigate the relationship between celiac disease and colchicine-resistant familial Mediterranean fever (crFMF) disease. METHODS: This prospective study was conducted at the Department of Pediatric Gastroenterology and Pediatric Rheumatology from October 2015 to August 2016. A total of 24 patients with crFMF were included in the study. We used 60 sex- and age-matched healthy subjects as a control group. Levels of total IgA and tissue transglutaminase (tTG) IgA antibody were measured in both groups. Those with increased level of tTG IgA were tested for anti-endomysium IgA antibodies (EMA). Gastroduodenoscopy and intestinal biopsy were planned for a definite diagnosis of celiac disease in patients with positive EMA. RESULTS: Of the 24 patients in this study, 18 (75.0%) were female. Only 4 (16.6%) of 24 patients were positive for tTG IgA. Patients with positive tTG IgA were then tested for EMA IgA antibodies and none of them had a positive result. Only one (1.6%) subject from the control group was positive for tTG IgA but EMA positivity was not detected. CONCLUSION: We did not found celiac disease in 24 children with crFMF. Since crFMF disease is rarely seen in general population, further studies with more patients are needed to provide more precise interpretation.

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.

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.
