Celiac disease (CeD) is a complex immune-mediated disorder that is triggered by dietary gluten in genetically predisposed individuals. CeD is characterized by inflammation and villous atrophy of the small intestine, which can lead to gastrointestinal complaints, malnutrition, and malignancies. Currently, diagnosis of CeD relies on serology (antibodies against transglutaminase and endomysium) and small-intestinal biopsies. Since small-intestinal biopsies require invasive upper-endoscopy, and serology cannot predict CeD in an early stage or be used for monitoring disease after initiation of a gluten-free diet, the search for non-invasive biomarkers is ongoing. Here, we summarize current and up-and-coming non-invasive biomarkers that may be able to predict, diagnose, and monitor the progression of CeD. We further discuss how current and emerging techniques, such as (single-cell) transcriptomics and genomics, can be used to uncover the pathophysiology of CeD and identify non-invasive biomarkers.

Celiac disease (CD) is a chronic, small-intestinal, immune-mediated enteropathy due to gluten exposition in genetically predisposed individuals. It occurs in about 1% of the population and often remains an underdiagnosed condition. This could be due to the fact that the adult population often lacks the classical signs and symptoms of CD, manifesting only atypical symptoms. In this review we analyzed the main extra-intestinal manifestations of CD which include cutaneous and endocrinological disorders, abnormal liver function tests, and neuropsychiatric features. When CD is not diagnosed and therefore is not treated with a gluten-free diet (GFD), it can predispose to severe complications, not only gastrointestinal. Thus, it is important for clinicians to quickly recognize the atypical manifestations of CD, considering that an early diagnosis can significantly impact on a patient’s prognosis.

ABSTRACT Introduction The purpose of this review is to provide an overview of the etiology, pathology, and treatments for celiac disease (CD), as well as to provide context as to how CD impacts the U.S. military. Materials and Methods To conduct this review, the authors surveyed recent epidemiology and immunology literature in order to provide a detailed summary of the current understanding of CD, its diagnosis, and the real-world impacts within the Department of Defense (DoD). Results We described the gluten proteins and both the immune response in CD. We further describe the underlying genetic risk factors and diagnosis and pathogenesis of the disease and conclude the review with a discussion of how current DoD regulations impact U.S. military readiness. Conclusion Celiac disease (CD) is an autoimmune disorder that results in damage to the small intestine. Ingestion of gluten in a CD patient is usually followed by villous atrophy in the small intestine, often along with other gastrointestinal symptoms. Around 1% of patients diagnosed with CD can experience complications if gluten-free diet is not followed, including intestinal lymphoma and hyposplenism. Therefore, a patient showing possible symptoms should discuss the diagnostic process with their healthcare providers to ensure adequate understanding of serological and genetic tests along with the histological examination of intestinal biopsy. Patients should seek consults with registered dietitians to structure their diets appropriately. Considering the prevalence and incidence of CD and gluten intolerances are increasing, the military should consider providing gluten-free Meals Ready-to-Eat as an option for all service members. Given the retention of service members with CD, subsequent admission of personnel with mild CD that does not affect the duties will allow the DoD access to a growing population of fully capable service members with critical technical skills who are eager to serve the USA.

Celiac disease is an immune mediated disorder elicited by the ingestion of gluten in genetically susceptible person and associated with some HLA subtypes. It is characterized by chronic inflammation of small intestine associated with villous atrophy. Symptoms usually appear when weaning from breast milk is done and gluten is introduced in diet. Failures to thrive, chronic diarrhea, vomiting abdominal distension are usual symptoms. Celiac crisis is rare but well known complication of celiac disease presenting with various systemic and metabolic manifestations like hypokalemia, hyponatremia, shock and bleeding diathesis. Celiac crisis usually has some underlying precipitating factor and is more common in patient with noncompliance with gluten free diet. We report a case of 14 year and three months old female child, a known case of celiac disease having the poor compliance with gluten free diet, presenting in celiac crisis with shock, refractory hypokalemia and bleeding diathesis.Kathmandu University Medical Journal Vol.12(4) 2014; 296-297

Potential celiac disease (PCD) is a heterogeneous disease; only some patients develop full celiac disease (CD), characterised by advanced atrophic changes in the small intestine. Few accurate prognostic factors exist for the progression of PCD; therefore, therapeutic decisions should be made on an individual basis in each case. Patients with clinical gastroenterological or parenteral symptoms often benefit from a gluten-free diet, and those left on a diet containing gluten should receive clinical, serological and histopathological supervision.

And Function

The ingestion of wheat gliadin (alcohol-soluble proteins, an integral part of wheat gluten) and related proteins induce, in genetically predisposed individuals, celiac disease (CD), which is characterized by immune-mediated impairment of the small intestinal mucosa. The lifelong omission of gluten and related grain proteins, i.e., a gluten-free diet (GFD), is at present the only therapy for CD. Although a GFD usually reduces CD symptoms, it does not entirely restore the small intestinal mucosa to a fully healthy state. Recently, the participation of microbial components in pathogenetic mechanisms of celiac disease was suggested. The present review provides information on infectious diseases associated with CD and the putative role of infections in CD development. Moreover, the involvement of the microbiota as a factor contributing to pathological changes in the intestine is discussed. Attention is paid to the mechanisms by which microbes and their components affect mucosal immunity, including tolerance to food antigens. Modulation of microbiota composition and function and the potential beneficial effects of probiotics in celiac disease are discussed.

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.

Gluten Sensitive Enteropathy

The celiac disease is an immune chronic condition with genetic transmission, caused by the intolerance to gluten. Gluten is a protein from cereals containing the following soluble proteins: gliadine, which is the most toxic, and the prolamins. The average prevalence is about 1% in USA and Europe, but high in Africa: 5.6% in West Sahara. In the pathogenesis several factors are involved: gluten as external trigger, genetic predisposition (HLA, MYO9B), viral infections, abnormal immune reaction to gluten. Severity is correlated with the number of intraepithelial lymphocytes, cryptic hyperplasia and villous atrophy, as well as with the length of intestinal involvement. The severity is assessed according to the Marsh–Oberhuber staging. Diagnostic criteria are: positive serological tests, intestinal biopsy, the reversal after gluten free diet (GFD). Beside refractory forms, new conditions have been described, like the non celiac gluten intolerance. In a time when more and more people adhere to GFD for nonscientific reasons, practitioners should be updated with the progress in celiac disease knowledge.
