    Celiac disease, with a prevalence around 1% of the general population, is the most common genetically-induced food intolerance in the world. Triggered by the ingestion of gluten in genetically predisposed individuals, this enteropathy may appear at any age, and is characterized by a wide variety of clinical signs and symptoms. Among them, gastrointestinal presentations include chronic diarrhea, abdominal pain, weight loss or failure to thrive in children; but extra-intestinal manifestations are also common, and actually appear to be on the rise. They include a large variety of ailments, such as dermatitis Herpetiformis, anemia, short stature, osteoporosis, arthritis, neurologic problems, unexplained elevation of transaminases, and even female infertility. For the clinician interested in oral diseases, celiac disease can lead to delayed tooth eruption, dental enamel hypoplasia, recurrent oral aphthae. Diagnosing celiac disease requires therefore a high degree of suspicion followed by a very sensitive screening test: serum levels of the autoantibody anti-tissue transglutaminase. A positive subject will then be confirmed by an intestinal biopsy, and will then be put on a strict gluten-free diet, that in most cases will bring a marked improvement of symptoms. Newer forms of treatment which in the future will probably be available to the non-responsive patients are currently being actively pursued. PMID:23496382

    Celiac disease is an inflammatory enteropathy, autoimmune-like, due to gluten intake in genetically predisposed persons with HLA-DQ2/DQ8 genotyping. Prevalence rates are approaching 1% of population in Europe and USA. Clinical expression of celiac disease is extremely various. Screening is based on detection of serum celiac antibodies and diagnosis is confirmed with duodenal biopsy. Treatment relies on gluten free diet (GFD) with eviction of wheat, barley and rye. GFD allows prevention of osteopenia, autoimmune diseases and malignant complications. The main cause of resistance to GFD because is its bad observance. PMID:26979028

    Celiac disease is a chronic intestinal disease caused by intolerance to gluten. It is characterized by immune-mediated enteropathy, associated with maldigestion and malabsorption of most nutrients and vitamins. In predisposed individuals, the ingestion of gluten-containing food such as wheat and rye induces a flat jejunal mucosa with infiltration of lymphocytes. The main symptoms are: stomach pain, gas, and bloating, diarrhea, weight loss, anemia, edema, bone or joint pain. Prevalence for clinically overt celiac disease varies from 1:270 in Finland to 1:5000 in North America. Since celiac disease can be asymptomatic, most subjects are not diagnosed or they can present with atypical symptoms. Furthermore, severe inflammation of the small bowel can be present without any gastrointestinal symptoms. The diagnosis should be made early since celiac disease causes growth retardation in untreated children and atypical symptoms like infertility or neurological symptoms. Diagnosis requires endoscopy with jejunal biopsy. In addition, tissue-transglutaminase antibodies are important to confirm the diagnosis since there are other diseases which can mimic celiac disease. The exact cause of celiac disease is unknown but is thought to be primarily immune mediated (tissue-transglutaminase autoantigen); often the disease is inherited. Management consists in life long withdrawal of dietary gluten, which leads to significant clinical and histological improvement. However, complete normalization of histology can take years.

    Celiac disease (CD) is a common autoimmune disorder, induced by the intake of gluten proteins present in wheat, barley and rye. Contrary to common belief, this disorder is a protean systemic disease, rather than merely a pure digestive alteration. CD is closely associated with genes that code HLA-II antigens, mainly of DQ2 and DQ8 classes. Previously, it was considered to be a rare childhood disorder, but is actually considered a frequent condition, present at any age, which may have multiple complications. Tissue transglutaminase-2 (tTG), appears to be an important component of this disease, both, in its pathogenesis and diagnosis. Active CD is characterized by intestinal and/or extra-intestinal symptoms, villous atrophy and crypt hyperplasia, and strongly positive tTG auto-antibodies. The duodenal biopsy is considered to be the “gold standard” for diagnosis, but its practice has significant limitations in its interpretation, especially in adults. Occasionally, it results in a false-negative because of patchy mucosal changes and the presence of mucosal villous atrophy is often more severe in the proximal jejunum, usually not reached by endoscopic biopsies. CD is associated with increased rates of several diseases, such as iron deficiency anemia, osteoporosis, dermatitis herpetiformis, several neurologic and endocrine diseases, persistent chronic hypertransami-nasemia of unknown origin, various types of cancer and other autoimmune disorders. Treatment of CD dictates a strict, life-long gluten-free diet, which results in remission for most individuals, although its effect on some associated extraintestinal manifestations remains to be established.

    Celiac disease affects about 1% of the European and North American population. The classical clinical presentation is with symptoms of malabsorption. Serologic studies demonstrate that most celiac patients present with oligosymptomatic (silent), latent, potential, and extraintestinal forms. The disease is defined as an immune-mediated systemic disorder of genetically disposed individuals (HLA-DQ2/8) induced by the alcohol-soluble fractions of cereals and characterized by gluten-dependent symptoms, celiac-specific antibodies (against tissue transglutaminase 2), and a Marsh 2-3 enteropathy. In the last 60 years, a strict and lifelong gluten-free diet has been demonstrated to be effective and safe, preventing most potential complications of the disease, including autoimmune disease, osteoporosis, infertility, prematurity, and malignancy. Among patients with celiac disease, the toxicity of oats seems to be less than wheat, barley, and rye. The introduction of oats into the diet of patients with celiac disease should increase taste, fiber content, diversity, compliance with the diet, and quality of life. The clinical studies provide limited results in favor of a general harmlessness of oats for celiac disease patients. Patients with celiac disease who consume oats (20-25 g/d for children, 50-70 g/d for adults) need proper follow-up. PMID:21939908

    Recent evidence regarding celiac disease has increasingly shown the role of innate immunity in triggering the immune response by stimulating the adaptive immune response and by mucosal damage. The interaction between the gut microbiota and the mucosal wall is mediated by the same receptors which can activate innate immunity. Thus, changes in gut microbiota may lead to activation of this inflammatory pathway. This paper is a review of the current knowledge regarding the relationship between celiac disease and gut microbiota. In fact, patients with celiac disease have a reduction in beneficial species and an increase in those potentially pathogenic as compared to healthy subjects. This dysbiosis is reduced, but might still remain, after a gluten-free diet. Thus, gut microbiota could play a significant role in the pathogenesis of celiac disease, as described by studies which link dysbiosis with the inflammatory milieu in celiac patients. The use of probiotics seems to reduce the inflammatory response and restore a normal proportion of beneficial bacteria in the gastrointestinal tract. Additional evidence is needed in order to better understand the role of gut microbiota in the pathogenesis of celiac disease, and the clinical impact and therapeutic use of probiotics in this setting.

    Celiac disease is an autoimmune disease, caused by a permanent intolerance to gluten, that occurs in genetically predisposed individuals. It causes enteropathy. In these individuals a prolonged exposure to gluten increases the risk of developing other pathologies, which may affect both developing dentition and oral mucosa. Clinical presentations are various and atypical. Celiac patients may have enamel hypoplasia, higher prevalence of dental caries, delayed eruption of teeth and lower jaw growth. These factors predispose to malocclusion. PMID:20540401

    The mode of presentation of patients with celiac disease has changed dramatically over the recent decades, with diarrheal or classic presentations becoming less common. This trend is most markedly seen in children, whose main presentations include recurrent abdominal pain, growth issues, and screening groups at risk. Among adults, presentations include diarrhea, anemia, osteoporosis, and recognition at endoscopy performed for gastroesophageal reflux disease, as well as screening. The groups most commonly screened include family members of patients with celiac disease, Down syndrome, and autoimmune diseases. PMID:23083982

    The prevalence of Celiac disease in the general population is approximately 1% and remains undiagnosed in a significant proportion of individuals. Its clinical presentation includes the classical malabsorption syndrome, unspecific and extra-intestinal manifestations, and silent celiac disease. The serologic diagnosis has an elevated sensitivity and specificity and, at least in adult population, it must be confirmed by biopsy in every case. Diagnosis in subjects already on gluten free diet includes HLA typing and gluten challenge with posterior serologic and histologic evaluation. The core of the treatment is the gluten free diet, which must be supervised by an expert nutritionist. Monitoring must be performed with serology beginning at 3-6 months, and with histology two years after the diagnosis, unless the clinical response is poor. Poor disease control is associated with complications such as lymphoma and small bowel adenocarcinoma. In the future, it is likely that new pharmacologic therapies will be available for the management of celiac disease. PMID:27092676

    Celiac disease is an autoimmune enteropathy, triggered by ingestion of gluten in genetically predisposed individuals. Since the use of anti-transglutaminase and anti-endomysium antibodies in the early 1990s, two main groups of clinical presentation can be identified: patients with a symptomatic form of the disease, and patients with a pauci (a)-symptomatic form detected during the work-up of another autoimmune disease or due to a family history of celiac disease. The prevalence of both forms of the disease is currently estimated between 1/100 and 1/400. Classical form of the disease is characterized by occurrence of diarrhoea, failure to thrive, and abdominal bloating in young infants in the months following gluten introduction. Serological tests show high level of anti-transglutaminase and anti-endomysium antibodies. Until recently, the diagnosis required duodenal biopsies that show villous atrophy. HLA genotype can help for diagnosis: the absence of the HLA-DQ2 or DQ8 alleles has a high negative predictive value. European guidelines recently proposed to reconsider the need for systematic endoscopy in typical symptomatic forms with high level of anti-transglutaminase and positive anti-endomysium. These recommendations are being assessed now. Currently, the gluten-free diet remains the only effective treatment for celiac disease. Children with celiac disease have to exclude from their diet all products containing wheat, barley and rye. Gluten-free diet causes clinical remission within a few weeks, but normalization of the small bowel mucosa and negativity of anti-transglutaminase antibodies are obtained in several months or even years. Gluten-free diet is useful to obtain clinical assessment, but also to prevent long-term complications of celiac disease, mainly osteoporosis, other autoimmune diseases, decreased fertility and cancers.

    Celiac disease is one of the most prevalent autoimmune gastrointestinal disorders but as the case of Ms. J illustrates, diagnosis is often delayed or missed. Based on serology studies, the prevalence of celiac disease in many populations is estimated to be approximately 1% and has been increasing steadily over the last 50 years. Evaluation for celiac disease is generally straightforward, and uses commonly available serologic tests, however the signs and symptoms of celiac disease are nonspecific and highly heterogeneous making diagnosis difficult. While celiac disease is often considered a mild disorder treatable with simple dietary changes, in reality celiac disease imparts considerable risks including reduced bone mineral density, impaired quality of life, and increased overall mortality. In addition, the gluten free diet is highly burdensome and can profoundly affect patients and their families. For these reasons, care of individuals with celiac disease requires prompt diagnosis and ongoing multidisciplinary management. PMID:21990301

    Celiac disease is a common systemic disorder that can have multiple hematologic manifestations. Patients with celiac disease may present to hematologists for evaluation of various hematologic problems prior to receiving a diagnosis of celiac disease. Anemia secondary to malabsorption of iron, folic acid, and/or vitamin B12 is a common complication of celiac disease and many patients have anemia at the time of diagnosis. Celiac disease may also be associated with thrombocytosis, thrombocytopenia, leukopenia, venous thromboembolism, hyposplenism, and IgA deficiency. Patients with celiac disease are at increased risk of being diagnosed with lymphoma, especially of the T-cell type. The risk is highest for enteropathy-type T-cell lymphoma (ETL) and B-cell lymphoma of the gut, but extraintestinal lymphomas can also be seen. ETL is an aggressive disease with poor prognosis, but strict adherence to a gluten-free diet may prevent its occurrence. PMID:16973955

    Celiac disease is much common than previously thought with a prevalence of 1/300, but most of cases are poorly symptomatic or silent. Fewer of half of patients report diarrhoea as a presenting symptom. In adults, the diagnosis should be considered, in case of isolated iron deficiency anaemia, neurological symptoms (ataxia, epilepsy), osteoporosis and arthralgia, infertility, dermatitis herpetiformis and abnormalities in liver tests. Characteristic histological features are total or subtotal villous atrophy associated with an increased number of intraepithelial lymphocytes. The most sensitive and specific circulating antibodies for the diagnosis are endomysial and transglutaminase IgA antibodies. The treatment of celiac disease requires a strict gluten free diet, but the observance to this diet is often difficult. In patients refractory to a strict gluten free diet, serious complications such as intestinal lymphoma or refractory sprue should be considered. PMID:11458609

    More than 50 % of untreated patients with celiac disease (CD) have bone loss detected by bone densitometry (dual-energy X-ray absorptiometry:DXA). Moreover, patients with CD are more likely to have osteoporosis and fragility fractures, especially of the distal radius. Although still controversial, we recommend DXA screening in all celiac disease patients, particularly in those with symptomatic CD at diagnosis and in those who present risk factors for fracture such as older age, menopausal status, previous fracture history, and familial hip fracture history. Bone microarchitecture, especially the trabecular network, may be deteriorated, explaining the higher fracture risk in these patients. Adequate calcium and vitamin D supplementation are also recommended to optimize bone recovery, especially during the first years of gluten free diet (GFD). If higher fracture risk persists after 1 or 2 years of GFD, specific osteoactive treatment may be necessary to improve bone health. PMID:26875096

    Celiac disease is an autoimmune disorder of the gastrointestinal tract. It is triggered by exposure to dietary gluten in genetically susceptible individuals. Gluten is a storage protein in wheat, rye, and barley, which are staples in many American diets. Celiac disease is characterized by chronic inflammation of the small intestinal mucosa, which leads to atrophy of the small intestinal villi and subsequent malabsorption. The condition may develop at any age. Intestinal manifestations include diarrhea and weight loss. Common extraintestinal manifestations include iron deficiency anemia, decreased bone mineral density, and neuropathy. Most cases of celiac disease are diagnosed in persons with extraintestinal manifestations. The presence of dermatitis herpetiformis is pathognomonic for celiac disease. Diagnosis is supported by a positive tissue transglutaminase serologic test but, in general, should be confirmed by a small bowel biopsy showing the characteristic histology associated with celiac disease. The presence of human leukocyte antigen alleles DQ2, DQ8, or both is essential for the development of celiac disease, and can be a useful genetic test in select instances. Treatment of celiac disease is a gluten-free diet. Dietary education should focus on identifying hidden sources of gluten, planning balanced meals, reading labels, food shopping, dining out, and dining during travel. About 5% of patients with celiac disease are refractory to a gluten-free diet. These patients should be referred to a gastroenterologist for reconsideration of the diagnosis or for aggressive treatment of refractory celiac disease, which may involve corticosteroids and immunomodulators.

    Refractory celiac disease is characterized by mucosal damage in patients with celiac disease despite a gluten-free diet. Little is known about the mechanisms that cause persistent intestinal inflammation in these patients. We performed a case-control study of 17 consecutive patients diagnosed with refractory celiac disease from 2001 through 2014 (median age, 51 y; 10 women) and 24 patients with uncomplicated celiac disease (controls) to determine whether refractory disease is associated with infection by lymphotropic oncogenic viruses. We performed real-time PCR analyses of duodenal biopsy samples from all patients to detect Epstein-Barr virus (EBV), human herpesvirus-8, and human T-cell lymphotropic virus-I, -II, or -III. We used in situ hybridization and immunohistochemical analyses to identify infected cells and viral proteins. We did not detect human herpesvirus-8 or human T-cell lymphotropic viruses in any of the biopsy specimens. However, 12 of 17 (70.5%) biopsy specimens from patients with refractory celiac disease were positive for EBV, compared with 4 of 24 (16.6%) biopsy specimens from controls (P < .001). EBV was detected in inflammatory cells and enterocytes. An analysis of latency- and replication-associated proteins confirmed active infection. Further studies are needed to determine whether EBV infection contributes to the pathogenesis of refractory celiac disease and enteropathy-associated T-cell lymphoma. PMID:27033429

    Celiac disease is an immune-mediated enteropathy in genetically predisposed individuals, triggered by gluten ingestion. Clinical manifestations include intestinal and extraintestinal symptoms. Affected individuals may also be completely asymptomatic. Nevertheless, an early diagnosis is essential in order to prevent long-term complications. Diagnostic approach involves serologic testing for tissue transglutaminase antibodies followed by duodenal biopsy in case of seropositivity. Until now, the only available treatment consists of a strict glute-free diet. Newer therapeutic strategies are currently being evaluated in clinical trials. PMID:27381303

    Celiac disease is a permanent intolerance to dietary gluten. Its well known features are abdominal symptoms, malabsorption of nutrients, and small-bowel mucosal inflammation with villous atrophy, which recover on a gluten-free diet. Diagnosis is challenging in that patients often suffer from subtle, if any, symptoms. The risk of clinically silent celiac disease is increased in various autoimmune conditions. The endocrinologist, especially, should maintain high suspicion and alertness to celiac disease, which is to be found in 2-5% of patients with insulin-dependent diabetes mellitus or autoimmune thyroid disease. Patients with multiple endocrine disorders, Addison's disease, alopecia, or hypophysitis may also have concomitant celiac disease. Similar heredity and proneness to autoimmune conditions are considered to be explanations for these associations. A gluten-free diet is essential to prevent celiac complications such as anemia, osteoporosis, and infertility. The diet may also be beneficial in the treatment of the underlying endocrinological disease; prolonged gluten exposure may even contribute to the development of autoimmune diseases. The diagnosis of celiac disease requires endoscopic biopsy, but serological screening with antiendomysial and antitissue transglutaminase antibody assays is an easy method for preliminary case finding. Celiac disease will be increasingly detected provided the close association with autoimmune endocrinological diseases is recognized. PMID:12202461

    Triggered by the ingestion of gluten in genetically predisposed individuals, celiac disease is the most common genetically based food intolerance in the world, with a prevalence among approximately 1% of the general population. This enteropathy may appear at any age and is characterized by a wide variety of clinical signs and symptoms that go well beyond the gastrointestinal tract. In young children, gastrointestinal presentations are common and include chronic diarrhea, failure to thrive, and abdominal distention; however, extraintestinal manifestations are becoming increasingly more common. They include numerous conditions such as dermatitis herpetiformis, anemia, dental enamel hypoplasia, recurrent oral aphthae, short stature, osteoporosis, arthritis, neurologic problems, unexplained elevation of transaminase levels, and female infertility. Therefore, diagnosing celiac disease requires a high degree of suspicion, followed by correct screening and a confirmatory test with an intestinal biopsy. After diagnosis, a strict gluten-free diet must be followed, which in most cases will bring a marked improvement of symptoms. However, there are important compliance and quality-of-life problems, especially in adolescents. PMID:24395055

    Celiac disease is a common autoimmune gastrointestinal disorder affecting multiple organs, precipitated in genetically vulnerable persons by the ingestion of gluten. Gluten is poorly digested and is presented to the intestinal mucosa as a large polypeptide. Binding to human leukocyte antigen-DQ2 and human leukocyte antigen-DQ8 molecules on antigen-presenting cells stimulates cellular and humeral immune reactions. Although common serological tests are available to diagnose celiac disease, the diagnosis of celiac disease is often delayed or missed because of lack of recognition as the disease presentation in adults is highly variable and may be asymptomatic. Celiac disease is a common secondary cause of metabolic bone disease and delayed treatment with gluten-free diet affects bone mineral density and fracture risk, so it is crucial to diagnose and treat celiac disease promptly. In this article, we will review recent studies of celiac disease in adults and provide practical, easily accessible information for busy clinicians. PMID:24090646

    Celiac disease is a permanent intolerance to gluten that leads to small-bowel mucosal villous atrophy during autoimmune processes in genetically predisposed individuals. At present the diagnosis of celiac disease is based on characteristic clinical symptoms, the results of serological investigations (tissue transglutaminase ten times the upper limit of normal, presence of antiendomysial antibodies – EMA) and positive results of genetic examinations. The aim of this study is to present a medical history of a family in which the mother and younger son were diagnosed with celiac disease (confirmed by genotype examination). Before the genetic examination, the father and the elder son were also suspected of suffering from this disease (they were on gluten-free diets). The authors emphasize the usefulness of HLA-DQ2/DQ8 determination in first-degree relatives of celiac patients. PMID:24868289

    Celiac disease or pulmonary haemosiderosis can be associated with several distinguished conditions. Pulmonary haemosiderosis is a rare, severe and fatal disease characterised by recurrent episodes of alveolar haemorrhage, haemoptysis and anaemia. Association of pulmonary haemosiderosis and celiac disease is extremely rare. We describe a case of celiac disease presented with dilated cardiomyopathy and pulmonary haemosiderosis without gastrointestinal symptoms of celiac disease. In addition, vitamin A deficiency was detected. This case suggests that celiac disease should be considered in patients with cardiomyopathy and/or pulmonary haemosiderosis regardless of the intestinal symptoms of celiac disease. PMID:23169927

    The diagnosis of celiac disease has long been based on the demonstration of gluten-induced small-bowel mucosal damage. However, due to the constantly increasing disease prevalence and limitations in the histology-based criteria there is a pressure towards more serology-based diagnostics. The serological tools are being improved and new non-invasive methods are being developed, but the constantly refined endoscopic and histologic techniques may still prove helpful. Moreover, growing understanding of the disease pathogenesis has led researchers to suggest completely novel approaches to celiac disease diagnostics regardless of disease activity. In this review, we will elucidate the most recent development and possible future innovations in the diagnostic techniques for celiac disease. PMID:26838683

    Celiac disease is a common autoimmune disease affecting 1% of the Western populations. It is an inappropriate immune response, in genetically susceptible patients to dietary wheat, rye, barley and oats. Treatment involves a Lifelong gluten-free diet that predisposes to low compliance due to limited variety, high cost and low palatability, imposing social pressure and affecting quality of life. The result is an urgent need for alternative therapeutic strategies. Based on the growing actual knowledge on the intestinal inflammatory cascade, mucosal immunology and genetics of celiac disease, new attractive potential therapies are emerging. Possibilities include: searching for low immunogenic wheat variants or strains pretreated with enzymes or binders for lower toxicity. Other strategies involve decreasing transepithelial uptake or dampening of the adaptive immune response by transglutaminase inhibitors or blockage of the HLA groove and immune modulation to shift the TH1 to TH2 profile. Developing biological therapy aims to decrease intestinal homing, adhesion and activity of inflammatory cells, counteract the pro-inflammatory cytokines, clonal intestinal T cells or mesenchymal stem cell replacement or mitogenic intestinal repair safety, cost, affordability and clinical effectiveness are of prime concern. Most of the above strategies showed promising results ex-vivo. The future will highlight the in-vivo winner. PMID:22991867

    Celiac disease (CD) determines neurologic manifestations in 10% of all CD patients. We describe the most common clinical manifestations as cerebellar ataxia, gluten encephalopathy, multiple sclerosis, peripheral neuropathies, sensorineural hearing loss, epilepsy, headache, depression, cognitive deficiencies and other less described clinical conditions. Our aim is to perform, as more as possible, a review about the most recent update on the topics in international literature. It is important to consider clinical neurological manifestations in celiac patients and to research these conditions also in the follow-up because they may start also one year after the start of gluten free diet (GFD) as peripheral neuropathy. The association with autism is analysed and possible new association with non-celiac gluten sensitivity (NCGS) are considered. PMID:26619901

    Celiac disease is induced by the consumption of gluten containing cereals (wheat, spelt, barley, rye). With a prevalence of ~ 1 %, it is the most common non-infectious chronic inflammatory intestinal disease worldwide. It manifests in all age groups, either classically with abdominal pain, diarrhoea and growth failure or weight loss, more commonly with indirect consequences of malabsorption, such as anaemia and osteoporosis, or with associated autoimmune diseases like type 1 diabetes, autoimmune thyroiditis or dermatitis herpetiformis. The pathogenesis of celiac disease is well explored. Gluten, the cereal storage protein, is not completely digested and reaches the intestinal mucosa where it activates inflammatory T cells, which cause atrophy of the resorptive villi. This T‑cell activation requires a genetic predisposition (the molecules HLA-DQ2 or -DQ8 on antigen-presenting immune cells). Moreover, the enzyme tissue transglutaminase (TG2) which is released in the mucosa increases the immunogenicity of the gluten peptides by a deamidation reaction. The test for serum antibodies to the autoantigen TG2 is one of the best diagnostic markers in medicine, which in combination with endoscopically obtained biopsies, secures the diagnosis of celiac disease. Despite these tools celiac disease is severely underdiagnosed, with 80-90 % of those affected being undetected. The untreated condition can lead to grave complications. These include the consequences of malabsorption, cancers (especially intestinal T‑cell lymphoma), and likely also the promotion of autoimmune diseases. The therapy of celiac disease, a strict gluten-free diet, is difficult to maintain and not always effective. Alternative, supporting pharmacological therapies are urgently needed and are currently in development. PMID:27273303

    2014-12-01

    Celiac disease is a chronic immune-mediated condition that develops in genetically predisposed individuals. It is characterized by the presence of circulating auto-antibodies in addition to an enteropathy and at times, other extra-intestinal manifestations triggered by exposure to the gliadin fraction of gluten, a family of proteins found in wheat, barley, and rye. There seems to be a rise in reported adverse reactions to gluten, an entity currently termed non-celiac gluten (or perhaps more accurately, wheat) sensitivity, where neither the enteropathy nor the auto-antibodies are present. Celiac disease has protean extra-intestinal manifestations, and an accurate diagnosis should be sought in people suffering from seemingly unrelated complaints, such as fatigue, anorexia, delayed puberty, short stature, decreased bone density, unusual skin rashes, unexplained iron deficiency, and infertility. The presence of an enteropathy, in conjunction with the positive serology, is considered the diagnostic gold standard for making the diagnosis of celiac disease. It is important to stress that the elimination of gluten, even in asymptomatic patients, brings about health benefits, particularly in relation to bone health, as well as a decrease in the incidence of small bowel malignancy, especially lymphoma. Better understanding of the pathophysiology of celiac disease and the molecular mechanisms involved in antigen recognition and processing has provided the impetus for the development of pharmacologic agents that might block the recognition of gluten and its conversion to a toxic antigenic target. Inhibition of tight junction dysregulation could also prevent or minimize the damage triggered by gluten. Work on genetically modified wheat cultivars has progressed, and the possibility of a vaccine to block the immune mediated trigger is being actively investigated. Education and guidance by a knowledgeable nutritionist or registered dietitian can go a long way in minimizing the

    Evidence indicates a well-established relationship between low bone mineral density (BMD) and celiac disease (CD), but data on the pathogenesis of bone derangement in this setting are still inconclusive. In patients with symptomatic CD, low BMD appears to be directly related to the intestinal malabsorption. Adherence to a strict gluten-free diet (GFD) will reverse the histological changes in the intestine and also the biochemical evidence of calcium malabsorption, resulting in rapid increase of BMD. Nevertheless, GFD improves BMD but does not normalize it in all patients, even after the recovery of intestinal mucosa. Other mechanisms of bone injury than calcium and vitamin D malabsorption are thought to be involved, such as proinflammatory cytokines, parathyroid function abnormalities, and misbalanced bone remodeling factors, most of all represented by the receptor activator of nuclear factor B/receptor activator of nuclear factor B-ligand/osteoprotegerin system. By means of dual-energy X-ray absorptiometry (DXA), it is now rapid and easy to obtain semiquantitative values of BMD. However, the question is still open about who and when submit to DXA evaluation in CD, in order to estimate risk of fractures. Furthermore, additional information on the role of nutritional supplements and alternative therapies is needed. PMID:22737164

    Celiac disease (CD) is characterized by an abnormal immune response in susceptible individuals to dietary gluten derived from wheat, rye and barley. The disease affects not only the small bowel mucosa, but also many other extraintestinal organs resulting bone, liver, neurologic, skin and reproductive system disorders. The details of the pathogenic mechanism are not perfectly clear yet, but it is now proved that both humoral and cellular immune responses are triggered and autoimmune mechanisms are implicated. Studies have shown association of different pregnancy outcomes with maternal celiac disease. In this review, the most frequent fetal and neonatal outcome related to CD are presented, with a special focus on intrautherine growth restriction (IUGR) and prematurity. The need of active case finding of CD is discussed. PMID:23998909

    Background In celiac disease (CD), intestinal epithelium damage occurs secondary to an immune insult and is characterized by blunting of the villi and crypt hyperplasia. Similarities between Hedgehog (Hh)/BMP4 downregulation, as reported in a mouse model, and CD histopathology, suggest mechanistic involvement of Hh/BMP4/WNT pathways in proliferation and differentiation of immature epithelial cells in the context of human intestinal homeostasis and regeneration after damage. Herein we examined the nature of intestinal crypt hyperplasia and involvement of Hh/BMP4 in CD histopathology. Methods and Findings Immunohistochemistry, qPCR and in situ hybridization were used to study a cohort of 24 healthy controls (HC) and 24 patients with diagnosed acute celiac disease (A-CD) intestinal biopsies. In A-CD we observed an increase in cells positive for Leucin-rich repeat-containing G protein-coupled receptor 5 (LGR5), an epithelial stem cell specific marker and expansion of WNT responding compartment. Further, we observed alteration in number and distribution of mesenchymal cells, predicted to be part of the intestinal stem cells niche. At the molecular level we found downregulation of indian hedgehog (IHH) and other components of the Hh pathway, but we did not observe a concurrent downregulation of BMP4. However, we observed upregulation of BMPs antagonists, gremlin 1 and gremlin 2. Conclusions Our data suggest that acute CD histopathology partially recapitulates the phenotype reported in Hh knockdown models. Specifically, Hh/BMP4 paradigm appears to be decoupled in CD, as the expansion of the immature cell population does not occur consequent to downregulation of BMP4. Instead, we provide evidence that upregulation of BMP antagonists play a key role in intestinal crypt hyperplasia. This study sheds light on the molecular mechanisms underlying CD histopathology and the limitations in the use of mouse models for celiac disease. PMID:26649570

    Introduction Celiac sprue most commonly presents with steatorrhea, abdominal pain, and weight loss. Celiac disease is now becoming more recognized for its atypical presentations. Anemia, osteoporosis, and childhood failure to thrive have been widely discussed. Objective In this paper, we present a case of nontraumatic intramuscular hemorrhage associated with prolongation of both prothrombin time and activated partial thromboplastin time. Main Results Coagulopathy, unmasked by the use of a nonsteroidal anti-inflammatory drug, was found to be attributable to vitamin K deficiency associated with malabsorption of multiple fat soluble vitamins. Celiac sprue was confirmed by small bowel biopsy. A review of the literature finds that, whereas asymptomatic prolongation of coagulation is relatively common in celiac sprue, clinical bleeding is a rare but described presentation. Conclusion This case emphasizes the importance of recognizing hemorrhage as an atypical manifestation of celiac disease and offers the opportunity to review the clinical and laboratory evaluation of a patient who presents with unexplained hemorrhage.

    Stem cells (SCs) are the key to tissue genesis and regeneration. Given their central role in homeostasis, dysfunctions of the SC compartment play a pivotal role in the development of cancers, degenerative disorders, chronic inflammatory pathologies and organ failure. The gastrointestinal tract is constantly exposed to harsh mechanical and chemical conditions and most of the epithelial cells are replaced every 3 to 5 d. According to the so-called Unitarian hypothesis, this renewal is driven by a common intestinal stem cell (ISC) residing within the crypt base at the origin of the crypt-to-villus hierarchical migratory pattern. Celiac disease (CD) can be defined as a chronic immune-mediated disease that is triggered and maintained by dietary proteins (gluten) in genetically predisposed individuals. Many advances have been achieved over the last years in understanding of the pathogenic interactions among genetic, immunological and environmental factors in CD, with a particular emphasis on intestinal barrier and gut microbiota. Conversely, little is known about ISC modulation and deregulation in active celiac disease and upon a gluten-free diet. Nonetheless, bone marrow-derived SC transplantation has become an option for celiac patients with complicated or refractory disease. This manuscript summarizes the “state of the art” regarding CD and ISCs, their niche and potential role in the development and treatment of the disease. PMID:24772248

    Both celiac disease and osteoporosis are common diseases which are considered an emerging problem in medicine. Celiac disease is a condition at high risk for secondary osteoporosis. Osteoporosis or osteopenia are typically present in untreated adult symptomatic celiac disease with an overt malabsorption syndrome, but is found in about 50 % in suboptimally treated celiac patients, subclinical patients and asymptomatic adult celiac patients, too. Etiology of pathologic bone alteration in celiac disease is multifactorial; however, two main mechanisms are involved: intestinal malabsorption and chronic inflammation. The evaluation of bone mineral metabolism (total calcium/albumin, 25-OH vitamin D3 and parathormone levels in serum) and bone mineral density (densitometry) is recommended in the clinical management of celiac patients. Many studies have demonstrated that bone mineral density values in adults show a good improvement in the first period after the institution of gluten-free diet, the improvement is then unsatisfactory and treatment with a mineral-active drug should probably be considered.

    Celiac disease is an enteropathy due to gluten intake in genetically predisposed persons (HLA DQ2/DQ8). Celiac disease occurs in adults and children at rates approaching 1% of population in Europe and USA. Celiac disease is extremely various and anaemia, oral aphthous stomatis, amenorrhea or articular symptoms may be the only revealing symptoms. Diagnosis releases on evidence of histological villous atrophy in proximal small bowel and presence of specific serum antibodies. Treatment relies on eviction of gluten. Gluten free diet allows prevention of malignant complications such as small bowel adenocarcinoma and lymphoma and osteopenia. The main cause of resistance to gluten free diet is its bad observance. On the contrary, serious complications of celiac disease, such as clonal refractory celiac sprue and intestinal T-cell lymphoma need to be screen. PMID:21621928

    Case finding for celiac disease (CD) is becoming increasingly common practice and is conducted in a wide range of clinical situations ranging from the presence of gastrointestinal symptoms to failure to thrive in children, prolonged fatigue, unexpected weight loss and anemia. Case finding is also performed in associated conditions, such as autoimmune thyroid disease, dermatitis herpetiformis and type 1 diabetes, as well as in patients with irritable bowel syndrome, unexplained neuropsychiatric disorders and first-degree relatives of patients with diagnosed CD. This aggressive active case finding has dramatically changed the clinical characteristics of newly diagnosed patients. For instance, higher numbers of patients who present with extraintestinal symptoms are now being diagnosed with CD. Current recommendations state that due to a high risk for complications if the disease remains undiagnosed, patients with extraintestinal symptoms due to CD require appropriate diagnosis and treatment. Despite criticism regarding the cost-effectiveness of case finding in CD, such an aggressive approach has been considered cost-effective for high-risk patients. The diagnosis of CD among patients with extraintestinal symptoms requires a high degree of awareness of the clinical conditions that carry a high risk for underlying CD. Also, understanding the correct use of specific serology and duodenal histology is key for an appropriate diagnostic approach. Both procedures combined are able to confirm diagnosis in the vast majority of cases. However, in certain circumstances, serology and even duodenal histology cannot confirm or rule out CD. A common cause of negative IgA serology is IgA deficiency. For such eventuality, IgG-based serological tests can help confirm the diagnosis. Importantly, some histologically diagnosed cases still remain seronegative despite exclusion of IgA deficiency. On the other hand, duodenal histology may be normal despite the presence of CD

    Celiac disease is a common, lifelong autoimmune disorder for which dietary control is the only accepted form of therapy. A strict gluten-free diet is burdensome to patients and can be limited in efficacy, indicating there is an unmet need for novel therapeutic approaches to supplement or supplant dietary therapy. Many molecular events required for disease pathogenesis have been recently characterized and inspire most current and emerging drug-discovery efforts. Genome-wide association studies (GWAS) confirm the importance of human leukocyte antigen genes in our pathogenic model and identify a number of new risk loci in this complex disease. Here, we review the status of both emerging and potential therapeutic strategies in the context of disease pathophysiology. We conclude with a discussion of how genes identified during GWAS and follow-up studies that enhance susceptibility may offer insight into developing novel therapies. PMID:26060114

    Celiac disease (CD) is an inflammatory disease of the small intestine. A complete management and differential diagnosis of such disease includes food intolerances, intestinal infections, and irritable bowel syndrome. We describe an 8-years-old adoptive girl from Congo with negative medical history. Patient followed for recurrent abdominal pain and diarrhea associated to Giardia infection, unresponsive to antiparasitic therapy. Persistence of symptoms despite antiparasitic therapy, prompted us to perform: 1- Blood screening of Celiac disease, which was negative; 2- Genetic evaluation of celiac disease, which revealed the presence of HLA-DQ2 heterodimer; and 3- Esophagogastroduodenoscopy, which showed duodenal villous atrophy and crypt hyperplasia, associated with Helicobacter Pylori infection. The child was treated in accordance with international recommendations using a Gluten-free diet and specific antibiotics, which lead to the resolution of the symptoms. Our patient's clinical history seems peculiar, considering that, recurrent Giardiasis may mimic the symptoms of Celiac disease and may simulate clinical and histological picture of active Celiac disease. Early diagnosis may help prevent the complications of untreated celiac disease. PMID:26309440

    Celiac disease (CD) is an immune-based condition affecting multiple organ systems. Clinical manifestations are manifold in form and number due to the multisystem nature of CD. There has been a progressive change in the clinical manifestations over the recent decades with fewer patients, both adults and children, presenting with a diarrheal, classical form. This, in children, is seen in only the youngest, while growth issues, screening at-risk groups and recurrent abdominal pain are the most common modes of presentation among children. Among adults, diarrhea is the most common presentation followed by anemia. Screening at-risk groups, metabolic bone disease and incidental recognition at endoscopy performed for reflux are the other main modes of presentation. The bulk of those with CD remain undiagnosed. The symptoms are often common, and increased medical education should lead to greater awareness in the medical community and an increased rate of diagnosis. PMID:25925914

    Celiac disease is a permanent intolerance to ingested gluten that results in immunologically mediated inflammatory damage to the small-intestinal mucosa. Celiac disease is associated with both human leukocyte antigen (HLA) and non-HLA genes and with other immune disorders, notably juvenile diabetes and thyroid disease. The classic sprue syndrome of steatorrhea and malnutrition coupled with multiple deficiency states may be less common than more subtle and often monosymptomatic presentations of the disease. Diverse problems such as dental anomalies, short stature, osteopenic bone disease, lactose intolerance, infertility, and nonspecific abdominal pain among many others may be the only manifestations of celiac disease. The rate at which celiac disease is diagnosed depends on the level of suspicion for the disease. Although diagnosis relies on intestinal biopsy findings, serologic tests are useful as screening tools and as an adjunct to diagnosis. The treatment of celiac disease is lifelong avoidance of dietary gluten. Gluten-free diets are now readily achievable with appropriate professional instruction and community support. Both benign and malignant complications of celiac disease occur but these can often be avoided by early diagnosis and compliance with a gluten-free diet. PMID:10075317

    Lymphadenopathy in patients with celiac disease is generally viewed with alarm due to the association between celiac disease and intestinal lymphoma. Four patients with celiac disease are described in whom significant mesenteric and paraaortic adenopathy was demonstrated by computed tomogrophy (CT). The subsequent clinical course of these patients revealed no evidence of lymphoma. In two patients with longstanding celiac disease and recent relapse, exploratory laparotomy revealed reactive hyperplasia in the enlarged glands; in one patient this was associated with intestinal ulceration, and in the other no underlying pathology was found. Follow-up CT scans in both these patients demonstrated regression of the findings with clinical improvement. In the other two patients, CT was performed as part of the initial evaluation.

    Patients with active celiac disease (CD) are more likely to have osteoporosis and increased risk of fractures. High-resolution peripheral quantitative computed tomography (HR-pQCT) permits three-dimensional exploration of bone microarchitectural characteristics measuring separately cortical and trabecular compartments, and giving a more profound insight into bone disease pathophysiology and fracture. We aimed to determine the volumetric and microarchitectural characteristics of peripheral bones-distal radius and tibia-in an adult premenopausal cohort with active CD assessed at diagnosis. We prospectively enrolled 31 consecutive premenopausal women with newly diagnosed CD (median age 29 years, range: 18-49) and 22 healthy women of similar age (median age 30 years, range 21-41) and body mass index. Compared with controls, peripheral bones of CD patients were significantly lower in terms of total volumetric density mg/cm(3) (mean ± SD: 274.7 ± 51.7 vs. 324.7 ± 45.8, p 0.0006 at the radius; 264.4 ± 48.7 vs. 307 ± 40.7, p 0.002 at the tibia), trabecular density mg/cm(3) (118.6 ± 31.5 vs. 161.9 ± 33.6, p<0.0001 at the radius; 127.9 ± 28.7 vs. 157.6 ± 15.6, p < 0.0001 at the tibia); bone volume/trabecular volume ratio % (9.9 ± 2.6 vs. 13.5 ± 2.8, p<0.0001 at the radius; 10.6 ± 2.4 vs. 13.1 ± 1.3, p < 0.0001 at the tibia); number of trabeculae 1/mm (1.69 ± 0.27 vs. 1.89 ± 0.26, p 0.009 at the radius; 1.53 ± 0.32 vs. 1.80 ± 0.26, p 0.002 at the tibia); and trabecular thickness mm (0.058 ± 0.010 vs. 0.071 ± 0.008, p < 0.0001 at the radius with no significant difference at the tibia). Cortical density was significantly lower in both regions (D comp mg/cm(3) 860 ± 57.2 vs. 893.9 ± 43, p 0.02; 902.7 ± 48.7 vs. 932.6 ± 32.6, p 0.01 in radius and tibia respectively). Although cortical thickness was lower in CD patients, it failed to show any significant inter-group difference (a-8% decay with p 0.11 in both bones). Patients with symptomatic CD (n = 22) had

  17. Iron deficiency anemia in celiac disease

    Iron is an important micronutrient that may be depleted in celiac disease. Iron deficiency and anemia may complicate well-established celiac disease, but may also be the presenting clinical feature in the absence of diarrhea or weight loss. If iron deficiency anemia occurs, it should be thoroughly evaluated, even if celiac disease has been defined since other superimposed causes of iron deficiency anemia may be present. Most often, impaired duodenal mucosal uptake of iron is evident since surface absorptive area in the duodenum is reduced, in large part, because celiac disease is an immune-mediated disorder largely focused in the proximal small intestinal mucosa. Some studies have also suggested that blood loss may occur in celiac disease, sometimes from superimposed small intestinal disorders, including ulceration or neoplastic diseases, particularly lymphoma. In addition, other associated gastric or colonic disorders may be responsible for blood loss. Rarely, an immune-mediated hemolytic disorder with increased urine iron loss may occur that may respond to a gluten-free diet. Reduced expression of different regulatory proteins critical in iron uptake has also been defined in the presence and absence of anemia. Finally, other rare causes of microcytic anemia may occur in celiac disease, including a sideroblastic form of anemia reported to have responded to a gluten-free diet. PMID:26309349

    In the past, celiac disease (CD), or intolerance to gluten, was considered a rare disease of infancy characterized by chronic diarrhea with malabsorption and delayed growth. Besides the overt enteropathy, there are other clinic and subclinical forms which appear later in life. Target organs are not limited to the gut, but include liver, thyroid, skin and female and male reproductive systems. CD interference on reproduction is related to the multifactorial nature of the disease, whose pathological manifestations can be modulated, besides gluten, by different concurrent genetic and environmental factors. CD induces malabsorption with consequent deficiencies of micronutrients such as iron, folic acid and vitamin K, which are essential for organogenesis, and fat-soluble vitamins important for spermatogenesis. Regarding endocrine disorders, the deficiencies of specific trace elements on ovarian function could explain its involvement in the increased risk of female osteoporosis in CD patients. Affected males show a picture of tissue resistance to androgens; the increases of follicle-stimulating hormone and prolactin, not associated with infertility, may indicate an imbalance at hypothalamus-pituitary level, with general effects on health. Since reproductive alterations are reversible, adoption of a gluten-free diet supported by early diagnosis is important. Therefore, the detection of early biomarkers, such as deficiencies of vitamins and/or iron and andrological or endocrinological dysfunctions, should trigger timely strategies for prevention and treatment.

    This national clinical guideline approved by the Danish Society for Gastroenterology and Hepatology describes the diagnosis and treatment of celiac disease (CD) in adults. CD is a chronic immune-mediated enteropathy of the small intestine triggered by the ingestion of gluten-containing proteins, which are found in wheat, rye, and barley. The disease prevalence is 0.5-1.0%, but CD remains under-diagnosed. The diagnosis relies on the demonstration of lymphocyte infiltration, crypt hyperplasia, and villous atrophy in duodenal biopsies. Serology, malabsorption, biochemical markers, and identification of specific HLA haplotypes may contribute to CD diagnosis. Classical CD presents with diarrhoea and weight loss, but non-classical CD with vague or extraintestinal symptoms is common. The treatment for CD is a lifelong gluten-free diet (GFD), which, in the majority of patients, normalises the small intestinal mucosa and absorption. Adherence to a GFD usually requires dietary advice from a clinical dietician. The monitoring of antibody levels and malabsorption markers is crucial during follow-up and allows for early treatment of disease complications. Important complications include osteoporosis, iron and vitamin deficiencies, and enteropathy-associated T-cell lymphoma. PMID:25872537

  1. Dietary guidelines and implementation for celiac disease.

    Medical nutrition therapy is the only accepted treatment for celiac disease. This paper summarizes a review of scientific studies using the gluten-free diet, nutritional risk factors, controversial elements of the diet, and its implementation in treating celiac disease. Treatment for celiac disease requires elimination of the storage proteins found in wheat, rye, and barley. The inclusion of oats and wheat starch is controversial. Research supports that oats may be acceptable for patients with celiac disease and can improve the nutritional quality of the diet. However, use of oats is not widely recommended in the United States because of concerns of potential contamination of commercial oats. Studies assessing the contamination of commercial oats are limited. Research indicates no differences in patients choosing a strict wheat starch-containing, gluten-free diet vs. a naturally gluten-free diet. Factors other than trace gluten may be the cause of continued villous atrophy in some patients. The impact of nutrient malabsorption caused from untreated celiac disease is well documented. The diet and gluten-free products are often low in B vitamins, calcium, vitamin D, iron, zinc, magnesium, and fiber. Few gluten-free products are enriched or fortified, adding to the risk of nutrient deficiencies. Patients newly diagnosed or inadequately treated have low bone mineral density, imbalanced macronutrients, low fiber intake, and micronutrient deficiencies. Also troubling is the increased incidence of obesity seen in persons with celiac disease following a gluten-free diet. Because of the nutritional risks associated with celiac disease, a registered dietitian must be part of the health care team that monitors the patient's nutritional status and compliance on a regular basis.

    Background. Symptoms of celiac disease negatively impact social activities and emotional state. Aim was to investigate the prevalence of altered eating behaviour in celiac patients. Methods. Celiac patients and controls completed a dietary interview and the Binge Eating Staircases, Eating Disorder Inventory (EDI-2), Eating Attitudes Test, Zung Self-Rating Depression Scale, State Trait Anxiety Inventory Forma Y (STAI-Y1 and STAI-Y2), and Symptom Check List (SCL-90). Results. One hundred celiac adults and 100 controls were not statistically different for gender, age, and physical activity. STAI-Y1 and STAI-Y2, Somatization, Interpersonal, Sensitivity, and Anxiety scores of the SLC-90 were higher in CD patients than controls. EDI-2 was different in pulse thinness, social insecurity, perfectionism, inadequacy, ascetisms, and interpersonal diffidence between CD and HC women, whilst only in interceptive awareness between CD and HC men. A higher EAT-26 score was associated with the CD group dependently with gastrointestinal symptoms. The EAT26 demonstrated association between indices of diet-related disorders in both CD and the feminine gender after controlling for anxiety and depression. Conclusion. CD itself and not gastrointestinal related symptoms or psychological factors may contribute pathological eating behavior in celiac adults. Eating disorders appear to be more frequent in young celiac women than in CD men and in HC. PMID:24369457

    We outline the use of quantitative techniques that are currently used for analysis of celiac disease. Image processing techniques can be useful to statistically analyze the pixular data of endoscopic images that is acquired with standard or videocapsule endoscopy. It is shown how current techniques have evolved to become more useful for gastroenterologists who seek to understand celiac disease and to screen for it in suspected patients. New directions for focus in the development of methodology for diagnosis and treatment of this disease are suggested. It is evident that there are yet broad areas where there is potential to expand the use of quantitative techniques for improved analysis in suspected or known celiac disease patients. PMID:25759524

    In the small intestine of celiac disease patients, dietary wheat gluten and similar proteins in barley and rye trigger an inflammatory response. While strict adherence to a gluten-free diet induces full recovery in most patients, a small percentage of patients fail to recover. In a subset of these refractory celiac disease patients, an (aberrant) oligoclonal intraepithelial lymphocyte population develops into overt lymphoma. Celiac disease is strongly associated with HLA-DQ2 and/or HLA-DQ8, as both genotypes predispose for disease development. This association can be explained by the fact that gluten peptides can be presented in HLA-DQ2 and HLA-DQ8 molecules on antigen presenting cells. Gluten-specific CD4+ T cells in the lamina propria respond to these peptides, and this likely enhances cytotoxicity of intraepithelial lymphocytes against the intestinal epithelium. We propose a threshold model for the development of celiac disease, in which the efficiency of gluten presentation to CD4+ T cells determines the likelihood of developing celiac disease and its complications. Key factors that influence the efficiency of gluten presentation include: (1) the level of gluten intake, (2) the enzyme tissue transglutaminase 2 which modifies gluten into high affinity binding peptides for HLA-DQ2 and HLA-DQ8, (3) the HLA-DQ type, as HLA-DQ2 binds a wider range of gluten peptides than HLA-DQ8, (4) the gene dose of HLA-DQ2 and HLA-DQ8, and finally,(5) additional genetic polymorphisms that may influence T cell reactivity. This threshold model might also help to understand the development of refractory celiac disease and lymphoma. PMID:20661732

The atypical patterns of clinical presentation in this age group sometimes can cause a delay in diagnosis. Given the lower sensitivity and specificity of serological tests in the aged population, clinical suspect often arises in the presence of complications (autoimmune disorders, fractures, and finally, malignancy) and must be supported by endoscopic and imaging tools. In this review, we highlight the incidence and prevalence of celiac disease in the elderly, the patterns of clinical presentation, diagnosis, and the most frequent complications, with the aim of increasing awareness and reducing the diagnostic delay of celiac disease even in the elderly population.

    Objective Celiac disease is associated with decreased bone density, however, the risk of fractures in celiac disease patients is unclear. We compared the prevalence of celiac disease between a group of women with hip fractures and a group of women undergoing elective joint replacement surgery and the association between celiac disease and vitamin D levels. Methods Two hundred eight community dwelling and postmenopausal women were recruited from Boston, MA (n=81) and Baltimore, MD (n=127). We measured tissue transglutaminase IgA by ELISA to diagnose celiac disease and 25-hydroxyvitamin D (25(OH)D) levels by radioimmunoassay in both women with hip fractures (n=157) and the control group (n=51), all of whom were from Boston. Subjects were excluded if they took any medications or had medical conditions that might affect bone. Results Median serum 25(OH)D levels were significantly lower (p< 0.0001) in the hip fracture cohorts compared to the elective joint replacement cohort (14.1 ng/ml vs. 21.3 ng/ml, respectively). There were no differences in the percentage of subjects with a positive tissue transglutaminase in the women with hip fractures versus the control group (1.91% vs. 1.61%, respectively). Conclusion Vitamin D levels are markedly reduced in women with hip fractures, however hip fracture patients did not show a higher percentage of positive tissue transglutaminase levels compared with controls. These data suggest that routine testing for celiac disease among hip fracture patients may not prove useful, although larger prospective studies among hip fracture subjects are needed. PMID:23732553

    The advent of highly reliable non-invasive celiac diagnostic tests has transformed the field of celiac disease, from diagnosis, to evaluation of epidemiology, to clinical and translational research. Serologic tests in their modern forms are highly sensitive and specific for diagnosis, allowing for consideration of avoidance of diagnostic intestinal biopsy in some settings. On the other hand, as predictors of intestinal damage and for use in monitoring disease activity, currently available non-invasive tests have been disappointing. Serologic tests, while a measure of disease activity, do not correlate well with histology or symptomatology and it is unclear if they predict long-term risk. Additionally, while the many clinically available tests have improved accessibility, tests can have widely different cut-off levels and overall performance, making comparison of levels in individual patients overtime and across populations quite difficult. In the future, we can expect to see improvement in the currently available serologic tests including tTG and DGP with expansion of the dynamic range of the tests and the celiac care community should push for standardization of assays that would simplify research and patient care. Additionally, current serologic tests are measures of the adaptive immune response in celiac disease but do not directly measure intestinal inflammation. Promising work on intestinal-fatty acid binding protein (I-FABP) and other assays which directly measure intestinal damage may compliment traditional serologic tests and further improve our ability to non-invasively diagnose and monitor celiac disease. The coming years hold promise for the continuing evolution of serum based tests in celiac disease with the possibility of substantial improvement of patient care and clinical research. PMID:25925929

    A gluten-free diet is currently the only effective means of treating individuals with celiac disease. Such a diet enables celiac patients to control their symptoms and avoid various complications associated with this condition. However, while the quality of gluten-free foods has significantly improved during recent decades, maintenance of a gluten-free diet does not necessarily ensure adequate nutritional intake. Because oats are an important source of proteins, lipids, vitamins, minerals, and fibre, their inclusion in a gluten-free diet might improve the nutritional status of a celiac patient. Although oats are included in the list of gluten-free ingredients specified in European regulations, their safety when consumed by celiac patients remains debatable. Some studies claim that pure oats are safe for most celiac people, and contamination with other cereal sources is the main problem facing people with this disease. However, it is necessary to consider that oats include many varieties, containing various amino acid sequences and showing different immunoreactivities associated with toxic prolamins. As a result, several studies have shown that the immunogenicity of oats varies depending on the cultivar consumed. Thus, it is essential to thoroughly study the variety of oats used in a food ingredient before including it in a gluten-free diet. PMID:26557006

    The clinical presentation of celiac disease in children is very variable and differs with age. The prevalence of atypical presentations of celiac disease has increased over the past 2 decades. Several studies in adults and children with celiac disease indicate that obesity/overweight at disease onset is not unusual. In addition, there is a trend towards the development of overweight/obesity in celiac patients who strictly comply with a gluten-free diet. However, the pathogenesis and clinical implications of the coexistence of classic malabsorption (e.g., celiac disease) and overweight/obesity remain unclear. This review investigated the causes and main clinical factors associated with overweight/obesity at the diagnosis of celiac disease and clarified whether gluten withdrawal affects the current trends of the nutritional status of celiac disease patients.

    Celiac disease is an autoimmune disorder of the small intestine that is more common than was previously thought. This disease is caused by an inappropriate immune response to wheat gluten, barley, and rye. Three main pathways cause celiac disease: the environmental trigger (gluten), genetic susceptibility, and unusual gut permeability. The only treatment currently available is a strict gluten-free diet. Unfortunately, a majority of patients have difficulty complying with this diet, and the response to therapy is poor. Therefore, alternative treatments are being developed, and new insights into the pathophysiology of celiac disease have led to research into novel therapies. New treatments include engineering gluten-free grains, decreasing intestinal permeability by blockage of the epithelial zonulin receptor, inducing oral tolerance to gluten with a therapeutic vaccine, and degrading immunodominant gliadin peptides using probiotics with endopeptidases or transglutaminase inhibitors. These nondiet-based therapies provide hope for enhanced, lifelong celiac disease management with improved patient compliance and better quality of life. PMID:23483819

    PubMed

    2005-04-01

    The symptoms of celiac disease are diverse, and the disease is often asymptomatic. Without active serologic screening, most cases probably remain undiagnosed. Recent serologic screening assays allow mass screening for the disease. However, there is no evidence as yet to suggest that symptom-free celiac disease patients run an increased risk of small intestinal lymphoma or other complications. The prevention of osteoporosis seems to be the strongest indicator for widespread screening today. Screening asymptomatic individuals for celiac disease may be even harmful. A lifelong gluten-free diet is not easy to maintain, and the subject's quality of life may deteriorate. It is also debatable whether patients found by active screening adhere to a gluten-free diet similarly to symptomatic ones. The cost-effectiveness of population screening is dubious. Serologic screening should be applied in individuals with even subtle symptoms indicative of celiac disease, such as subclinical-isolated iron deficiency. In various autoimmune conditions, the risk of celiac disease is approximately 5% and, in individuals with affected first-degree relatives, 15%. Infertility, neurologic symptoms such as polyneuropathy, ataxia, epilepsy with posterior cerebral calcification, and osteoporosis are conditions in which celiac disease should be kept in mind. Elevated aminotransferases and liver failure can lead to a diagnosis of celiac disease. Evidence today does not support mass screening of celiac disease. Instead, increased alertness should be observed in patients at risk of the condition. PMID:15825117

    Celiac disease (gluten-sensitive enteropathy) is currently regarded as a multisystem autoimmune disorder; its clinical signs and symptoms do not involve merely the gastrointestinal tract but are associated with several other medical specialties, including orthopaedics and traumatology. In orthopaedic and trauma patients, celiac disease should be suspected in the following diagnoses: osteomalacia, premenopausal osteoporosis, post-menopausal osteoporosis more severe than expected and refractory to medication, osteoporosis in men under 55 years of age, recurrent bone fractures in the limbs, large joint arthralgia or arthritis of unclear aetiology, erosive spondyloarthropathy particularly in patients with the history of chronic diarrhoea, anaemia or associated autoimmune disorders (type 1 diabetes mellitus or autoimmune thyreopathy), and in women with secondary amenorrhea or early menopause. The orthopaedist or trauma surgeon should be aware of suspected celiac disease in patients who do not respond adequately to the standard treatment of pain related to the musculoskeletal system, in patients with recurrent fractures of the limb bones and in young patients with suspected secondary osteoporosis. With the use of appropriate screening methods, celiac disease as-yet undiagnosed can be revealed. A long-life gluten-free diet in these patients results in the alleviation of metabolic osteopathy and joint and muscle problems, in reduced requirements of analgesic and antiphlogistic drugs as well as in reduced risks of fracture.

    Abstract Tissue transglutaminase (tTG) plays an important role in celiac disease pathogenesis and antibodies to tTG are a diagnostic marker of gluten-sensitive enteropathy. The aim of this study was to investigate the localization of tTG in the duodenal mucosa in control tissues and in different histological stages of celiac disease by using a commercial and a novel set of anti-tTG monoclonal antibodies, to see whether this assessment can be useful for diagnostic purpose. The distribution of tTG was firstly evaluated in 18 untreated celiac patients by using a commercial monoclonal antibody (CUB7402) against tissue transglutaminase enzyme and directed against the loop-core region of the enzyme. Thereafter, in further 30 untreated celiac patients we employed three newly characterized anti-tTG monoclonal antibodies produced against recombinant human-tTG. The epitopes recognized are located in three distinct domains of the protein corresponding to the core, C1 and C2 protein structure. Eleven age- and sex-matched patients with chronic duodenitis acted as controls. All subjects underwent upper endoscopy to obtain biopsy samples from the duodenum. Overall, we found that (i) tTG is equally expressed in CD at different stages of disease; (ii) tTG is expressed, at similar level, in CD and controls with duodenitis. Assessment of tTG level in biopsy samples by immunohistochemical methods is not useful in the clinical diagnostic work-up of CD. PMID:18373732

    Background Celiac disease is an immune-mediated small bowel disorder that develops in genetically susceptible individuals upon exposure to dietary gluten. Celiac disease could have extra-intestinal manifestations that affect women’s reproductive health. The aim of this study was to investigate fertility and outcomes of pregnancy among women with celiac disease. Methods In a retrospective cohort study, we analyzed information collected from patients at a tertiary care celiac center and from members of 2 national celiac disease awareness organizations. Women without celiac disease were used as controls. Women completed an anonymous online survey, answering 43 questions about menstrual history, fertility, and outcomes of pregnancy (329 with small bowel biopsy-confirmed celiac disease and 641 controls). Results Of the 970 women included in the study, 733 (75.6%) reported that they had been pregnant at some point; there was no significant difference between women with celiac disease (n=245/329, 74.5%) and controls (488/641, 76.1%; P=0.57). However, fewer women with celiac disease than controls (79.6% vs. 84.8%) gave birth following 1 or more pregnancies (P=0.03). Women with celiac disease had higher percentages of spontaneous abortion than controls (50.6% vs. 40.6%; P=0.01), and of premature delivery (23.6% vs. 15.9% among controls; P=0.02). The mean age at menarche was higher in the celiac disease group (12.7 years) than controls (12.4 years; P=0.01). Conclusions In a retrospective cohort analysis examining reproductive features of women with celiac disease, we associated celiac disease with significant increases in spontaneous abortion, premature delivery, and later age of menarche.

    The association between celiac disease and type 1 diabetes mellitus is well known. Up to now, celiac disease prevalence in children and adults with type 1 diabetes in Sicily has not been reported. The aim of this study was to assess the prevalence of celiac disease in patients with type 1 diabetes mellitus who come from a defined geographical area in western Sicily and to investigate the clinical features of these subjects. The records of 492 consecutive patients with type 1 diabetes mellitus referred in a period of 5 years were analyzed. During the period of the survey, out of 492 patients with type 1 diabetes, 22 (4.5 %) had a previous diagnosis of celiac disease. There were 14 females and 8 males; these patients showed a mean age of 13 years at diabetes onset. Diagnosis of celiac disease was often simultaneous or subsequent to that of diabetes. Autoimmune thyroiditis was coexisting in 8 patients (36 %). Our data confirm, in a Sicilian population, the not unusual association between celiac disease and type 1 diabetes, although prevalence rate is lower than in others Italian studies. Autoimmune thyroiditis is present with high prevalence in these patients. Celiac disease diagnosis often followed onset of type 1 diabetes, particularly in female subjects with a young age at diabetes onset; therefore, in these subjects, an active search for the presence of celiac disease is warranted for many years after appearance of diabetes.

    Patient: Male, 46 Final Diagnosis: Celiac crisis Symptoms: Abdominal pain • chronic diarrhea • lightheadedness • weakness • weight loss Medication: — Clinical Procedure: — Specialty: Gastroenterology and Hepatology Objective: Rare disease Background: Celiac disease is a hypersensitivity enteropathy that can have various presentations in adults. Rarely, patients can present with severe lab abnormalities, dehydration and weight loss caused by celiac disease – a celiac crisis. Case Report: A 46-year-old male with a past medical history significant for diabetes mellitus, type 2 (DM2) and recently treated Bell’s Palsy presented to the emergency room complaining of weakness, diarrhea and lightheadedness. On presentation, the patient had a systolic blood pressure (SBP) of 60 mm Hg and a lactic acidosis with pH of 7.28. Infectious etiologies of diarrhea were ruled out. The patient had an EGD which showed erythema of the duodenal bulb. Serum anti-gliadin and anti-TTG IgA were both elevated suggesting Celiac disease. Biopsies showed histopathology consistent with celiac disease. The patient’s diarrhea resolved after initiation of a gluten free diet. He gained 25 kilograms after discharge and did not require further hospitalizations for diarrhea. Conclusions: Celiac crisis is a very rare presentation of celiac disease in adults but nonetheless should be considered in patients with marked metabolic derangements in the setting of osmotic diarrhea. Treatment consists of a gluten free diet and may require management with steroids and total parenteral nutrition (TPN). PMID:27492679

    Celiac disease (CD) or gluten sensitive enteropathy is relatively common in western populations with prevalence around 1%. With the recent availability of sensitive and specific serological testing, many patients who are either asymptomatic or have subtle symptoms can be shown to have CD. Patients with CD have modest increases in risks of malignancy and mortality compared to controls. The mortality among CD patients who comply poorly with a gluten-free diet is greater than in compliant patients. The pattern of presentation of CD has altered over the past three decades. Many cases are now detected in adulthood during investigation of problems as diverse as anemia, osteoporosis, autoimmune disorders, unexplained neurological syndromes, infertility and chronic hypertransaminasemia of uncertain cause. Among autoimmune disorders, increased prevalence of CD has been found in patients with autoimmune thyroid disease, type 1 diabetes mellitus, autoimmune liver diseases and inflammatory bowel disease. Prevalence of CD was noted to be 1% to 19% in patients with type 1 diabetes mellitus, 2% to 5% in autoimmune thyroid disorders and 3% to 7% in primary biliary cirrhosis in prospective studies. Conversely, there is also an increased prevalence of immune based disorders among patients with CD. The pathogenesis of co-existent autoimmune thyroid disease and CD is not known, but these conditions share similar HLA haplotypes and are associated with the gene encoding cytotoxic T-lymphocyte-associated antigen-4. Screening high risk patients for CD, such as those with autoimmune diseases, is a reasonable strategy given the increased prevalence. Treatment of CD with a gluten-free diet should reduce the recognized complications of this disease and provide benefits in both general health and perhaps life expectancy. It also improves glycemic control in patients with type 1 diabetes mellitus and enhances the absorption of medications for associated hypothyroidism and osteoporosis. It

    Celiac disease (CeD) is one of the most common immune-mediated diseases. Symptoms and disease activity are incompletely controlled by the gluten-free diet, which is currently the only available therapy. Although no therapies are yet approved, there is a growing field of candidates and an improving understanding of the regulatory pathway. In this review, we briefly discuss the epidemiology, pathophysiology, and current treatment paradigm for CeD. We also review the major classes of therapies being considered for CeD and discuss extensively what is known and can be surmised regarding the regulatory pathway for approval of a CeD therapeutic. The coming years will see an increasing number and diversity of potential therapies entering clinical trials and hopefully the first approved agents targeting this significant unmet medical need. Although biomarkers including histology and serology will always be important in therapeutic clinical trials, they currently lack the necessary evidence linking them to improved patient outcomes required for use as primary outcomes for drug approval. For this reason, patient-reported outcomes will likely be primary end points in Phase III CeD trials for the foreseeable future. PMID:27021196

    Celiac disease is an autoimmune disorder resulting from gluten intolerance and is based on a genetically predisposition. Symptoms occur upon exposure to prolamin from wheat, rye, barley and related grain. The pathogenesis of celiac disease has not yet been sufficiently elucidated but is being considered as an autoimmune process. At its core are the deamidation of prolamin fragments, the building of specific antibodies and the activation of cytotoxic T-cells. The immunological inflammatory process is accompanied by structural damages of the enterocytes (villous atrophy, colonization and crypt hyperplasia). The symptoms and their extent depend on the type of the celiac disease; classic and non-classic forms are being distinguished (atypical, oligosymptomatic, latent and silent celiac disease). Characteristics of the classic presentation are malabsorption syndrome and intestinal symptoms such as mushy diarrhea and abdominal distension. The diagnosis of celiac disease is based on four pillars: Anamnesis and clinical presentation, serological evidence of coeliac specific antibodies (IgA-t-TG; IgA-EmA), small intestine biopsy and improvement of symptoms after institution of a gluten-free diet. The basis of the therapy is a lifelong gluten-free diet, i. e. wheat, rye, barley, spelt, green-core, faro-wheat, kamuth and conventional oats as well as food items obtained therefrom. Small amounts of up to 50 mg gluten per day are usually tolerated by most patients; amounts of > or = 100 mg/day lead mostly to symptoms. Gluten-free foods contain < or = 20 ppm or 20 mg/kg (Sign: symbol of the 'crossed ear' or label 'gluten-free'). At the beginning of the therapy the fat and lactose intake may need to be reduced; also the supplementation of single micronutrients (fat-soluble vitamins, folic acid, B12, iron, and calcium) may be required. Alternative therapies are being developed but have not yet been clinically tested. PMID:24266248

    Idiopathic pulmonary hemosiderosis is a severe and potentially fatal disease characterized by recurrent episodes of alveolar hemorrhage, hemoptysis, and anemia. His association with celiac disease, described as Lane- Hamilton syndrome, could be due to the fact that both entities share a common pathogenic immune pathway. We report two patients of 13 years who consulted for hemoptysis and severe anemia that had not responded to immunosuppressive treatment with pulses of methyl prednisolone, oral meprednisone and hydroxychloroquine. Although both children highlight the absence of gastrointestinal symptoms at the time of consultation, the dosage of anti-endomysial and anti-transglutaminase antibodies was positive and biopsy confirmed the presence of intestinal enteropathy. It is emphasized that in patients with diffuse alveolar hemorrhage, even in the absence of gastrointestinal symptoms, the concomitant presence of celiac disease should be evaluated. If celiac disease is present, the incorporation of a gluten-free diet helps to control the symptoms, allows reducing the immunosuppressive treatment and improves the clinical course of both entities.

Some less sensitive individuals may be able to tolerate barley and oats in small quantities. All other foods are acceptable, including the cereals corn, rice, buckwheat, millet and sorghum, as well as malt-flavored breakfast cereals. Wine, spirits, beer and ale are also acceptable unless otherwise contraindicated. Monosodium glutamate, other food additives and pharmaceutical preparations are also acceptable. The ingredients of prepackaged processed foods are listed on the labels. Patients with celiac disease must examine labels to ensure that they avoid the harmful cereals. With appropriate precautions they need not be concerned about eating away from home. PMID:7139445

    Celiac disease is a genetically-based intolerance to gluten. In the past, celiac disease has been considered a rare disease of infancy characterized by chronic diarrhea and delayed growth. Besides the overt enteropathy, there are many other forms which appear later in life; target organs are not limited to the gut, but include liver, thyroid, skin and reproductive tract. It is now recognized that celiac disease is a relatively frequent disorder; the overall prevalence is at least 1:300 in Western Europe. Celiac disease may impair the reproductive life of affected women, eliciting delayed puberty, infertility, amenorrhea and precocious menopause. Clinical and epidemiological studies show that female patients with celiac disease are at higher risk of spontaneous abortions, low birth weight of the newborn and reduced duration of lactation. No adequate studies are available on the rate of birth defects in the progeny of affected women; however, celiac disease induces malabsorption and deficiency of factors essential for organogenesis, e.g. iron, folic acid and vitamin K. The overall evidence suggests that celiac disease patients can be a group particularly susceptible to reproductive toxicants; however, the pathogenesis of celiac disease-related reproductive disorders still awaits clarification. At present, like the other pathologies associated with celiac disease, the possible prevention or treatment of reproductive effects can only be achieved through a life-long maintenance of a gluten-free diet.

    Celiac disease is an intestinal disorder that develops as a result of interplay between genetic and environmental factors. HLA genes along with non-HLA genes predispose to the disease. Linkage studies have failed to identify chromosomal regions other than the HLA region which have major effects, indicating the existence of multiple non-HLA predisposing genes with modest effects. Association studies have shown that CTLA4 or a closely located gene is one of these genes. The primary HLA association in the majority of celiac disease patients is with DQ2 (DQA1*05/DQB1*02) and in the minority of patients with DQ8 (DQA1*0301/DQB1*0302). Gluten reactive CD4+ T cells can be isolated from small intestinal biopsies of celiac patients but not from controls. DQ2 or DQ8, but not other HLA molecules carried by patients, present peptides to these T cells. A number of distinct T cell gluten epitopes exist, most of them posttranslationally modified by deamidation. DQ2 and DQ8 bind the epitopes such that the glutamic acid residues created by deamidation are accommodated in pockets that have a preference for negatively charged side chains. There is evidence that deamidation in vivo is mediated by the enzyme tissue transglutaminase (tTG). Overall, the results point to control of the immune response to gluten by intestinal T cells restricted by the DQ2 or DQ8 molecules. This is likely to be a critical checkpoint for the development of celiac disease and could explain the dominant genetic role of HLA in this disorder. The products of the other predisposing genes may participate in pathway(s) that lead(s) to lesion formation. The minor genetic effects of the non-HLA genes could indicate a lack of critical checkpoints along these pathways, or that there are several pathways leading to the lesion formation. PMID:11501889

    Because of the wide variations in the clinical presentation of celiac disease and because treatment exists that is effective in most cases, screening of the general population for celiac disease has been considered. There is still no evidence that patients who have symptom-free celiac disease are at increased risk of small intestinal lymphoma or other complications. Prevention of osteoporosis seems to be the strongest indicator for widespread screening today [22]. The major cause of failure to respond to a gluten-free diet is continuing ingestion of gluten, but other underlying diseases must be considered. Many different drugs (eg, anti-tumor necrosis factor [TNF]-alpha) have been used in patients who have RCD [23]. Steroid treatment has been reported to be effective even in patients who have underlying early EATL. Histologic recovery in patients who have celiac disease usually takes several months but can take up to 1 year, even if the patient remains on a strict gluten-free diet. Some patients report celiac-related symptoms for months after a single gluten intake. The definitions for RCD in literature vary. The authors consider the definition give by Daum and colleagues [24] suitable. They defined true RCD as villous atrophy with crypt hyperplasia and increased IELs persisting for more than 12 months in spite of a strict gluten-free diet. If a patient is not responding well to a gluten-free diet, three considerations are necessary: (1) the initial diagnosis of celiac disease must be reassessed;(2) the patient should be sent to a dietician to check for errors in diet or compliance problems, because problems with the gluten-free diet are the most important cause for persisting symptoms; (3) other reasons for persisting symptoms (eg, pancreatic insufficiency, irritable bowel syndrome, bacterial overgrowth, lymphocytic colitis, collagenous colitis, ulcerative jejunitis, protein-losing enteropathy,T-cell lymphoma, fructose intolerance, cavitating lymphadenopathy, and

    Celiac disease is, as we know it, rather than being a rare and incurable disease until the 1950's, both quite common in screening studies and readily treatable. Three conditions are triggered by gluten consumption: celiac disease, the skin rash dermatitis herpetiformis and gluten ataxia. We describe our follow up for out clinic management, as evidence based data about such an approach are lacking in current literature. No food, beverages or medications containing any amount of gluten can be taken. Compliance is often difficult especially when patients are asymptomatic. We control a cohort, in daily practice, of over 700 adult patients. The majority of patients manage the diet without any problems. We describe our follow up in general, for serology, laboratory and histology. Forty percent of our newly diagnosed celiac patients do have a BMI over 25 kg/m(2). An appropriate attitude for this problem is lacking. The problem of slowly weaning off Dapsone over 5-10 years in DH is recognized. The bone density is checked in all newly diagnosed celiac patients. We control, if necessary, by telephone and lab controls done in local cities and see our patients only every two years face-to-face for follow up. The main question is if the adherence to a GFD, quality of life and prevention of complications is improved by visiting a dedicated celiac clinic. We hope to standardize this attitude on evidence data in the years to come. PMID:26060110

CD was known already to ancient Greeks as κοιλιακός (keeleeakoss) i.e. disease of the abdominal cavity hence celiac. Focus of this Commentary article is on rather complex definition of CD and its emerging new forms the example of which is non-celiac gluten sensitivity. It is becoming evident that to formulate more effective treatments, these associations and newly identified disease entities deserve attention from both academic and clinical communities.

    Cereal crops and cereal consumption have had a vital role in Mankind’s history. In the recent years gluten ingestion has been linked with a range of clinical disorders. Gluten-related disorders have gradually emerged as an epidemiologically relevant phenomenon with an estimated global prevalence around 5%. Celiac disease, wheat allergy and non-celiac gluten sensitivity represent different gluten-related disorders. Similar clinical manifestations can be observed in these disorders, yet there are peculiar pathogenetic pathways involved in their development. Celiac disease and wheat allergy have been extensively studied, while non-celiac gluten sensitivity is a relatively novel clinical entity, believed to be closely related to other gastrointestinal functional syndromes. The diagnosis of celiac disease and wheat allergy is based on a combination of findings from the patient’s clinical history and specific tests, including serology and duodenal biopsies in case of celiac disease, or laboratory and functional assays for wheat allergy. On the other hand, non-celiac gluten sensitivity is still mainly a diagnosis of exclusion, in the absence of clear-cut diagnostic criteria. A multimodal pragmatic approach combining findings from the clinical history, symptoms, serological and histological tests is required in order to reach an accurate diagnosis. A thorough knowledge of the differences and overlap in clinical presentation among gluten-related disorders, and between them and other gastrointestinal disorders, will help clinicians in the process of differential diagnosis.

    Celiac disease is increasingly recognized autoimmune enteropathy caused by a permanent gluten intolerance. Gluten is the main storage protein of wheat, in genetically predisposed individuals. Celiac disease risk in first degree relatives is about 10%. Diarrhea and changes of bowel movement, observed as well in celiac disease as in IBS, may lead to misdiagnosis of IBS basing on the Rome criteria or may be associated with coexistence of both diseases. The aim of the study was to assess the celiac disease prevalence in patients with irritable bowel syndrome. The study group comprised 200 patients (120 women and 80 men) aged 18-78 years (mean: 46.7 years) with diarrhoeal form of irritable bowel syndrome (IBS), according to the Rome criteria II. At the beginning and after a three month period anti tissue transglutaminase antibodies (IgA tTG) were estimated. Gastroscopy with biopsy where performed in those with IgA tTG titre above 1/200. 40 patients were immunologically positive and 14 of them have histopathologically proven celiac disease. In the group of patients with detected celiac disease, gluten free diet was applied besides the treatment with trimebutin or mebewerin, recommended for IBS. After 6 months the decrease of IgA tTG titre in the serum was observed. In 5 of these patients IgA tTG level was negative. It was associated with the significant decrease of clinical symptoms, such as diarrhea and flatulence. The remaining symptoms, such as abdominal pain, feeling of incomplete defecation demanded continuation of IBS treatment. With regard to often atypical celiac disease symptoms--adult active searching should be performed to differentiate from irritable bowel syndrome. PMID:19689036

    BACKGROUND In some studies inflammatory bowel disease (IBD) and celiac disease were considered to be associated and some belive that this association may influence the prognosis of IBD. However, there is a cosiderable controversy regarding this association. Therefore ,we aimed to assess the association of these two common digestive diseases and evaluate the complications of this association. METHODS In this comparative study, 200 patients with ulceritive colitis (UC) and 206 patients with Crohn’s disease (CD) were evaluated for celiac disease using relevant diagnostic tests and pathologic studies. Total IgA, IgA tissue transgulaminase antibody and specific IgA anti endomysial antibody were asseyed. In cases of IgA deficiency, total IgG and IgG tissue TG and IgG anti endomyseal Ab were measured. Patients with increased specific IgA and IgG antibodies for celiac disease, underwent endoscopy and 4 standard samples were obtained. Our results were compared with the results of the prevalence study of celiac disease in the general population. Data were analyzed using analytic and descriptive statistics at a significance level of 5%. RESULTS Among the studied patients, 1 patient with UC had elevated IgA anti tTG antibody and IgA anti-endomysial antibody who underwent endoscopy and celiac was confirmed on pathology. Hence, of the 200 patientswith UC, the diagnosis of celiac disease was confirmed in 1 patient (1:200) with no significant difference with the prevalence of celiac disease in the general population (1:166). However, none of our patients with Crohn’s disease had celiac disease (0:206). CONCLUSION We found no significant difference in the prevalence of celiac disease between patients with UC and the general population. Since most of our participants had a mild level of Crohn’s activation, none of those with Crohn’s disease had celiac disease. Complications of IBD including sclerosing cholangitis, may be more common in patients with concurrent celiac disease

    Celiac disease is a chronic, immune-mediated disorder, characterized by small intestinal inflammation and villous atrophy after the ingestion of gluten by genetically susceptible individuals. Several extraintestinal manifestations have been associated to celiac disease. Eosinophilic esophagitis is a primary disorder of the esophagus characterized by upper gastrointestinal symptoms, absence of gastroesophageal reflux disease and more than 15 eosinophils per high-power field in biopsy specimens. Both celiac disease and eosinophilic esophagitis are caused by aberrant, but distinct, immune responses to ingested antigens and can be responsive to restricted food intake. The aim of this review is to assess whether there is an association between these two pathologies. In the majority of the studies examined, including the studies in pediatric population, the prevalence of eosinophilic esophagitis in subjects with celiac disease was about 10-times that of the general population. We suggest searching for eosinophilic esophagitis in all children undergoing endoscopy for suspicious celiac disease. PMID:23974065

    Objective Celiac disease is an intestinal disorder identified by mucus inflammation, villous atrophy and crypt hyperplasia. This disorder can be controlled by elimination of gluten from daily diet. Patients with celiac disease are at greater risk of gastrointestinal malignancy and non-Hodgkin lymphoma than are the general population. This study tries to present the value of gluten patch test for diagnosis of celiac disease. Methods In this investigation, the study population was divided into case and control groups. The case group consisted of patients with celiac disease. The control group were patients involved in celiac disease but suffering from other gastrointestinal disorders. Both gluten patch and placebo patch were attached to the skin between the scapulas. The results were read twice: 48 hours and 96 hours after the patch was applied. Patients who showed irritation reactions were withdrawn from this study. The results were analysed by SPSS software, Spearman's test, chi square, and Mann–Whitney tests. Findings The value obtained from the gluten patch test after 96 hours are as follows: specification at 95%, sensitivity at 8%, positive prediction value at 67%, and negative prediction value at 43%. Conclusion It can be concluded that the gluten patch test is not an efficient test for screening of celiac disease, however, it can be useful for diagnosis of celiac disease if employed and studied with clinical symptoms and serologic and biopsy tests. Furthermore, we should doubt our judgment if the result of gluten patch test for the patient with celiac disease is positive. PMID:23056837

    Celiac disease, or gluten-sensitive enteropathy, is defined as a state of heightened immunologic responsiveness to ingested gluten (from wheat, barley, or rye) in genetically susceptible individuals. Ingestion of the offending proteins leads to inflammation and intestinal mucosal damage, which may result in a spectrum of gastrointestinal symptoms, nutritional abnormalities, and systemic complications ranging from anemia and osteoporosis to secondary autoimmunity and malignancy. The genetic influence in the pathogenesis of celiac disease is indicated by its familial occurrence. Celiac disease does not develop unless a person has alleles that encode for human leukocyte antigen DQ2 or DQ8 proteins. The clinical picture of celiac disease has changed considerably during the past 30 years. Diarrhea, which was the presenting symptom in > 90% of celiac disease patients before 1981, is now the chief complaint in < 40%. In contrast, the increased frequency of atypical celiac disease presentations, including anemia and bone disease, is revealed by the widespread availability of serologic testing. An association between celiac disease and autoimmune disorders, such as type 1 diabetes, autoimmune thyroid disease, and Sjögren's syndrome, has been well documented. The tissue transglutaminase immunoglobulin antibody and the endomysial immunoglobulin antibody are the most sensitive and specific serologic tests, respectively, for identifying individuals who need to undergo an intestinal biopsy. If the suspicion of celiac disease is high, intestinal biopsy should be pursued even if serologic tests are negative. The gold standard for the diagnosis of celiac disease is a small bowel biopsy showing villous atrophy. The treatment for celiac disease is lifelong adherence to a gluten-free diet (GFD). Despite the proven benefits of the GFD, it can be exceedingly difficult to completely avoid gluten-containing foods, and adherence to a GFD is estimated to be only 45% to 80%. PMID:25702766

    This guideline presents recommendations for the diagnosis and management of patients with celiac disease. Celiac disease is an immune-based reaction to dietary gluten (storage protein for wheat, barley, and rye) that primarily affects the small intestine in those with a genetic predisposition and resolves with exclusion of gluten from the diet. There has been a substantial increase in the prevalence of celiac disease over the last 50 years and an increase in the rate of diagnosis in the last 10 years. Celiac disease can present with many symptoms, including typical gastrointestinal symptoms (e.g., diarrhea, steatorrhea, weight loss, bloating, flatulence, abdominal pain) and also non-gastrointestinal abnormalities (e.g., abnormal liver function tests, iron deficiency anemia, bone disease, skin disorders, and many other protean manifestations). Indeed, many individuals with celiac disease may have no symptoms at all. Celiac disease is usually detected by serologic testing of celiac-specific antibodies. The diagnosis is confirmed by duodenal mucosal biopsies. Both serology and biopsy should be performed on a gluten-containing diet. The treatment for celiac disease is primarily a gluten-free diet (GFD), which requires significant patient education, motivation, and follow-up. Non-responsive celiac disease occurs frequently, particularly in those diagnosed in adulthood. Persistent or recurring symptoms should lead to a review of the patient's original diagnosis to exclude alternative diagnoses, a review of the GFD to ensure there is no obvious gluten contamination, and serologic testing to confirm adherence with the GFD. In addition, evaluation for disorders associated with celiac disease that could cause persistent symptoms, such as microscopic colitis, pancreatic exocrine dysfunction, and complications of celiac disease, such as enteropathy-associated lymphoma or refractory celiac disease, should be entertained. Newer therapeutic modalities are being studied in

    To further define intraepithelial lymphocytes (IELs) in celiac disease (CD) and giardiasis, IELs were probed for the presence of cytolytic granules containing granzyme B (GrB) and T-cell-restricted intracellular antigen (TIA)-1. The expression of TIA-1, GrB, CD3 (T-cell-receptor-associated complex), and Leu-7 (subset of natural killer cells) was studied by a sensitive three-step immunoperoxidase technique. Stained IELs were determined quantitatively, and results were expressed as number of stained IELs per 100 epithelial cells (ECs). The relative content in labeled lamina propria lymphocytes was determined and expressed as the percentage of all lamina propria cells counted. When compared with controls, CD3+ and GrB+ IELs were significantly increased (P < 0.0004) in CD paralleled by an increase in TIA-1+ IELs (P < 0.0004). In CD, the highest numbers of IELs containing GrB were found in subjects with a flat mucosa (median, 38 IELs/100 ECs, P < 0.0004), followed by cases with shortened and blunted villi (median, 8 IELs/100 ECs, P < 0.0004) and, finally, CD patients with an intact villous architecture (median, 0.5 IELs/100 ECs, P < 0.02). Except for cases with giardiasis, Leu-7+ IELs were virtually absent in all groups as were GrB+ IELs in the controls and in subjects with giardiasis. In the lamina propria of CD subjects, GrB+ lymphocytes were also significantly increased (P < 0.001), whereas controls and cases with giardiasis were essentially free of GrB+ cytotoxic T lymphocytes. The percentage of CD3+ lamina propria lymphocytes was nearly equal in all groups. In humans and mice, extensive studies revealed a GrB expression to be absolutely restricted to activated cytotoxic T lymphocytes and natural killer cells. TIA-1, on the other hand, is considered a marker of resting T lymphocytes possessing cytolytic potential. We therefore conclude that IELs are cytotoxic T cells that are in a resting state in the normal small bowel and in giardiasis. In CD, they become

    Introduction Currently, the only treatment for celiac disease is a gluten free diet, and there is an increased desire for alternative therapies. In vitro and in vivo models of celiac disease have been generated in order to better understand the pathogenesis of celiac disease, and this review will discuss these models as well as the testing of alternative therapies using these models. Areas Covered The research discussed describes the different in vitro and in vivo models of celiac disease that currently exist and how they have contributed to our understanding of how gluten can stimulate both innate and adaptive immune responses in celiac patients. We also provide a summary on the alternative therapies that have been tested with these models and discuss whether subsequent clinical trials were done based on these tests done with these models of celiac disease. Expert Opinion Only a few of the alternative therapies that have been tested with animal models have gone on to clinical trials; however, those that did go on to clinical trial have provided promising results from a safety standpoint. Further trials are required to determine if some of these therapies may serve as an effective adjunct to a gluten free diet to alleviate the adverse affects associated with accidental gluten exposure. A “magic-bullet” approach may not be the answer to celiac disease, but possibly a future cocktail of these different therapeutics may allow celiac patients to consume an unrestricted diet.

    To determine the prevalence of celiac disease in children and adolescents with migraine, the authors investigated serum levels of tissue transglutaminase antibody immunoglobulin A and total immunoglobulin A from 81 children with migraine and in a healthy control group of 176 children. Study participants who were positive for tissue transglutaminase immunoglobulin A antibodies underwent a duodenal biopsy. Two patients in the migraine group (2.5%) and 1 in the control group (0.57%) tested positive for serum tissue transglutaminase immunoglobulin A antibodies (P > .05). Duodenal biopsy did not confirm celiac disease in both groups, and these patients were considered "potential celiac" cases. In the present study, children with migraine did not exhibit a higher prevalence rate of celiac disease compared with healthy controls. Therefore, the screening test for celiac disease is not a necessary part of the management of migraine in children. PMID:26887413

    The face of celiac disease has changed significantly over the past 50 years. With the advent of new noninvasive and more sensitive screening tools, it has become increasingly apparent that this disease presents in a heterogeneous fashion, with symptomatic disease only occurring in a small number of patients. Furthermore, great insights have been made into the disease's genetic and immunological components, thus increasing the medical community's understanding of the disease. The current gold standard for diagnosis is histological confirmation, and the cornerstone of therapy is lifelong elimination of gluten. Further advances in immunobiological techniques will most likely aid in earlier detection and commencement of the appropriate diet, thus preventing the development of associated complications.

    Celiac disease, and, more generally, gluten intolerance, is a growing problem worldwide, but especially in North America and Europe, where an estimated 5% of the population now suffers from it. Symptoms include nausea, diarrhea, skin rashes, macrocytic anemia and depression. It is a multifactorial disease associated with numerous nutritional deficiencies as well as reproductive issues and increased risk to thyroid disease, kidney failure and cancer. Here, we propose that glyphosate, the active ingredient in the herbicide, Roundup(®), is the most important causal factor in this epidemic. Fish exposed to glyphosate develop digestive problems that are reminiscent of celiac disease. Celiac disease is associated with imbalances in gut bacteria that can be fully explained by the known effects of glyphosate on gut bacteria. Characteristics of celiac disease point to impairment in many cytochrome P450 enzymes, which are involved with detoxifying environmental toxins, activating vitamin D3, catabolizing vitamin A, and maintaining bile acid production and sulfate supplies to the gut. Glyphosate is known to inhibit cytochrome P450 enzymes. Deficiencies in iron, cobalt, molybdenum, copper and other rare metals associated with celiac disease can be attributed to glyphosate's strong ability to chelate these elements. Deficiencies in tryptophan, tyrosine, methionine and selenomethionine associated with celiac disease match glyphosate's known depletion of these amino acids. Celiac disease patients have an increased risk to non-Hodgkin's lymphoma, which has also been implicated in glyphosate exposure. Reproductive issues associated with celiac disease, such as infertility, miscarriages, and birth defects, can also be explained by glyphosate. Glyphosate residues in wheat and other crops are likely increasing recently due to the growing practice of crop desiccation just prior to the harvest. We argue that the practice of "ripening" sugar cane with glyphosate may explain the recent

    The edible seeds of the quinoa plant contain small quantities of alcohol-soluble protein which, after peptic-tryptic digestion, are unable to agglutinate K562(s) cells. When separated by affinity chromatography on sepharose-6B coupled with mannan, peptic-tryptic digest separated in two fractions. Fraction B peptides (about 1% of total protein) were shown to agglutinate K562(s) cells at a very low concentration, whereas peptides in fraction A and in the mixed fraction A+B were inactive, suggesting that fraction A contains protective peptides that interfere with the agglutinating activity of toxic peptides in fraction B.

    Celiac disease is a gastrointestinal disorder characterized by inflammation, leading to injury to the mucosal lining of the small intestine. The inflammation occurs when gliadin, a protein found in such gluten-containing foods as wheat, rye, and barley, is ingested by genetically susceptible individuals. The mucosal damage and subsequent malabsorption of nutrients leads to various complications. Researchers estimate that more than 2 million people in the United States have celiac disease-a prevalence that is greater than was previously believed. Approximately 60,000 Americans are diagnosed annually with celiac disease. Until recently, diagnosis has been complicated by the fact that the indicators of celiac disease are nonspecific. However, because of the development of new, easy-to-administer serology tests, diagnosis has become much less complicated. After conducting a review of the literature, the authors recommend a serologic testing sequence for diagnosis of celiac disease and urge that adults and children with an assortment of symptoms be tested for this disease. Common signs and symptoms of celiac disease include anemia, arthralgia, fatigue, infertility, neuropathy, and weight loss, in addition to such gastrointestinal symptomatology as abdominal pain, anorexia, bloating, constipation, and diarrhea. The only treatment for patients with celiac disease remains a gluten-free diet. PMID:16585382

    This chapter provides a brief overview of current animal models for studying celiac disease, with a focus on generating HLA transgenic mouse models. Human Leukocyte Antigen class II molecules have been a particular target for transgenic mice due to their tight association with celiac disease, and a number of murine models have been developed which had the endogenous MHC class II genes replaced with insertions of disease susceptible HLA class II alleles DQ2 or DQ8. Additionally, transgenic mice that overexpress interleukin-15 (IL-15), a key player in the inflammatory cascade that leads to celiac disease, have also been generated to model a state of chronic inflammation. To explore the contribution of specific bacteria in gluten-sensitive enteropathy, the nude mouse and rat models have been studied in germ-free facilities. These reductionist mouse models allow us to address single factors thought to have crucial roles in celiac disease. No single model has incorporated all of the multiple factors that make up celiac disease. Rather, these mouse models can allow the functional interrogation of specific components of the many stages of, and contributions to, the pathogenic mechanisms that will lead to gluten-dependent enteropathy. Overall, the tools for animal studies in celiac disease are many and varied, and provide ample space for further creativity as well as to characterize the complete and complex pathogenesis of celiac disease.

    An epidemic of celiac disease is being witnessed in India as well as several other parts of the world. Awareness is important for early diagnosis and treatment so as to avoid long-term morbidity as well as irreversible complications. However, the key for resolution of the disease is good compliance to a gluten-free diet. Unfortunately, the current scenario in India is that either gluten free foods are not easily available or are expensive and often not tested. This is especially true in schools and colleges and smaller towns. In addition, the stigma attached to gluten-free food makes it socially undesirable, and this is made worse by the lack of knowledge among peers, family members, advisors, and even health care providers. We need to make a strong pitch to overcome the confusion regarding the disease as well as the diet to avoid psychological and medical complications. PMID:27335528

    Celiac disease has one of the strongest associations with HLA (human leukocyte antigen) class II markers of the known HLA-linked diseases. This association is primarily with the class II serologic specificities HLA-DR3 and -DQw2. The authors previously described a restriction fragment length polymorphism (RFLP) characterized by the presence of a 4.0-kilobase Rsa I fragment derived from an HLA class II ..beta..-chain gene, which distinguishes the class II HLA haplotype of celiac disease patients from those of many serologically matched controls. They now report the isolation of this ..beta..-chain gene from a bacteriophage genomic library constructed from the DNA of a celiac disease patient. Based on restriction mapping and differential hybridization with class II cDNA and oligonucleotide probes, this gene was identified as one encoding an HLA-DP ..beta..-chain. This celiac disease-associated HLA-DP ..beta..-chain gene was flanked by HLA-DP ..cap alpha..-chain genes and, therefore, was probably in its normal chromosomal location. The HLA-DP..cap alpha..-chain genes of celiac disease patients also were studied by RFLP analysis. Celiac disease is associated with a subset of HLA-DR3, -DQw2 haplotypes characterized by HLA-DP ..cap alpha..- and ..beta..-chain gene RFLPs. Within the celiac-disease patient population, the joint segregation of these HLA-DP genes with those encoding the serologic specificities HLA-DR3 and -DQw2 indicates: (i) that the class II HLA haplotype associated with celiac disease is extended throughout the entire HLA-D region, and (ii) that celiac-disease susceptibility genes may reside as far centromeric on this haplotype as the HLA-DP subregion.

    Background Celiac disease can present in children and adults with a variety of manifestations including a rare complication known as ulcerative jejunitis. The latter has been associated with refractory celiac disease in adult onset patients. The objective of this case report is to describe the first pediatric case of ulcerative jejunitis in celiac disease, diagnosed by capsule endoscopy, which was not associated with refractory celiac disease. Case presentation The 9 year old girl presented with a history of abdominal pain and vomiting. Laboratory investigations revealed a slightly elevated IgA tissue transglutaminase antibody level in the setting of serum IgA deficiency. Initial upper endoscopy with biopsies was not conclusive for celiac disease. Further investigations included positive IgA anti-endomysium antibody, and positive HLA DQ2 typing. Video capsule endoscopy showed delayed appearance of villi until the proximal to mid jejunum and jejunal mucosal ulcerations. Push enteroscopy with biopsies subsequently confirmed the diagnosis of celiac disease and ulcerative jejunitis. Immunohistochemical studies of the intraepithelial lymphocytes and PCR amplification revealed surface expression of CD3 and CD8 and oligoclonal T cell populations. A repeat capsule study and upper endoscopy, 1 year and 4 years following a strict gluten free diet showed endoscopic and histological normalization of the small bowel. Conclusion Ulcerative jejunitis in association with celiac disease has never previously been described in children. Capsule endoscopy was essential to both the diagnosis of celiac disease and its associated ulcerative jejunitis. The repeat capsule endoscopy findings, one year following institution of a gluten free diet, also suggest that ulcerative jejunitis is not always associated with refractory celiac disease and does not necessarily dictate a poor outcome.

    Celiac disease is an autoimmune enteropathy caused by gluten in genetically predisposed individuals. In celiac disease, adaptive and innate immune activation results in intestinal damage and a wide range of clinical manifestations. In the past, celiac disease was thought to result in signs and symptoms solely related to the gastrointestinal tract. Now, more than half of the adult population presents with extra-intestinal manifestations that can also be expected to improve on a gluten-free diet. For this reason, it is recommended that physicians have a low threshold of suspicion for celiac disease. Current knowledge of the immune pathogenesis of this autoimmune disease has served as a catalyst for the development of novel diagnostic tools and therapeutics. Over the years, highly sensitive and specific serological assays, in addition to genetic markers, have been found to target specific steps in the cascade pathway of celiac disease. Also the advent of the gluten challenge has enabled experts to design diagnostic algorithms and monitor clinical responses in clinical trials. The gluten challenge has provided substantial benefit in the advance of novel therapeutics as an adjuvant treatment to the gluten free diet. Generally, a strict gluten-free diet is highly burdensome to patients and can be limited in its efficacy. Alternative therapies—including gluten modification, modulation of intestinal permeability and immune response—could be central to the future treatment of celiac disease. PMID:25326000

While this may be beneficial for couples facing idiopathic infertility or those from particular risk groups, screening involves its own risks and expenses, and has not been consistently proven effective for the general population while pregnant. The present editorial discusses the potential advantages and disadvantages of screening during pregnancy and examines when screening may be helpful. PMID:18818937

    Celiac disease is caused by sensitivity to wheat gluten in genetically susceptible individuals. The etiological role of the other wheat-related cereals, barley, rye, and oats, is still debated. In order to investigate this issue further, in this study we examined the immune response of celiac mucosal T cell lines to fractions from all four cereals. Cell stimulation was assessed by measuring proliferation (employing (3)H-thymidine incorporation) or cytokine (IL-2, IFN-gamma) production. All five T cell lines demonstrated immunoreactivity to protein fractions from the four related cereals. In some cell lines, reactivity to wheat, barley, and rye was only evident when these cereal fractions had been pretreated with tissue transglutaminase. This study confirms the similar T cell antigenic reactivity of these four related cereals and has implications for their exclusion in the gluten-free diet. However, despite oats stimulation of T cell lines, this cereal does not activate a mucosal lesion in most celiac patients. PMID:16416236

    Celiac disease is characterized by a gluten-induced damage of the small bowel in sensitive individuals that may cause malabsorption. Non-intestinal inflammatory diseases may trigger immunologic gluten intolerance in susceptible people and the HCV virus may be considered as a suitable candidate. Interferon therapy could precipitate symptom onset in subjects with silent celiac disease. In fact, symptoms such as diarrhea, anemia, and weight loss may occur during interferon therapy and are associated with serological positivity of anti-tranglutaminase antibodies. To date, considering the available literature data, it is very difficult to support a firm association between HCV chronic hepatitis and celiac disease. Thus, such a serological screening in HCV patients before starting interferon therapy should not be recommended. However, serology for celiac disease must be considered in patients who develop diarrhea and/or weight loss during such therapy. PMID:27458507

    Celiac disease (CD) is a chronic, small intestinal, immune-mediated enteropathy triggered by exposure to dietary gluten in genetically susceptible individuals. Currently, lifelong adherence to a gluten-free diet (GFD) is the only available treatment. However, GFD alone is not sufficient to relieve symptoms, control small intestinal inflammation and prevent long-term complications in many patients. The GFD has its challenges including issues related to adherence, lifestyle restrictions and cost. As a result, there is growing interest in and a need for non-dietary therapies to manage this condition. In recent years, different targets in the immune-mediated cascade of CD have been identified in clinical and pre-clinical trials for potential therapies. This review will discuss the latest non-dietary therapies in CD, including endopeptidases, modulators of enterocyte tight junctions and agents involved in gluten tolerization and immunomodulation. We will also discuss the potential implications of approved therapeutics on CD clinical practice. PMID:25864708

    Celiac disease is a chronic immune-mediated disorder induced in genetically susceptible individuals after ingestion of gluten proteins. An early diagnosis is of highest importance. Ultrasound might show small-bowel intussusception. We present a toddler with one month history of diarrhea and abdominal ultrasound showing ileo-ileal intussusception. Specific serological markers for celiac disease were positive. The duodenal endoscopy showed normal architecture but pathology indicated fully developed celiac disease (Marsh 3c). In conclusion, toddlers, who have even a short history of diarrhea with ultrasound showing ileo-ileal intussusception, can be suspected of celiac disease by positive serologic markers and can be confirmed by duodenal biopsy and pathology.

    The publication of papers on the topic of gluten related disorders has substantially increased over the last few years. This has motivated healthcare professionals to pay attention not only to celiac disease and wheat allergy but also to a condition termed nonceliac gluten sensitivity (NCGS). Until now this condition has been diagnosed clinically on the basis of exclusion criteria and clinical response to gluten withdrawal. In addition, recent research in this field has shown that other food components distinct from gluten are implicated in NCGS cases, thereby changing our general understanding of NCGS diagnosis in either individuals on gluten containing diets or those already following a gluten-free diet with no proper diagnostic work-up of celiac disease. With this in mind, the assessment of NCGS will require extensive knowledge of celiac disease manifestations and the laboratory tests commonly performed during diagnosis of celiac disease.

We determined how many patients with celiac disease are actually followed. Methods We collected data on 122 patients with biopsy-proven celiac disease, diagnosed between 1996 and 2006 in Olmsted County, Minnesota (70% women, median age of 42 years) for whom complete medical records and verification of residency were available. We determined the frequency at which patients received follow-up examinations, from 6 months to 5 years after diagnosis. The Kaplan-Meier method was used to estimate event rates at 1 and 5 year(s). Patients were classified according to categories of follow-up procedures recommended by the American Gastroenterology Association (AGA). Results We estimated that by 1 and 5 year(s) after diagnosis with celiac disease, 41.0% and 88.7% of the patients had follow-up visits, 33.6% and 79.8% were assessed for compliance with a gluten-free diet, 3.3% and 15.8% met with a registered dietitian, 2.5% and 18.1% had an additional intestinal biopsy, and 22.1% and 65.6% received serologic testing for markers of celiac disease. Among 113 patients (93%) who were followed for more than 4 years, only 35% received follow-up analyses that were consistent with AGA recommendations. Conclusions Patients with celiac disease are not followed consistently. Follow-up examinations are often inadequate and do not follow AGA recommendations. Improving follow-up strategies for patients with celiac disease could improve management of this disease. PMID:22610009

    At present, strict and lifelong gluten-free diet is the only effective treatment for celiac disease. Even small amounts of gluten (50 mg/day) can be immunogenic; therefore all food and food items and drugs that contain gluten and its derivatives must be eliminated completely from the diet. While prescribing gluten-free diet is easy; the key to the success is the dietary counseling by a nutrition specialist and maintenance of adherence to GFD by the patient. In recent times, a number of targets to halt the process of immunological injury have been explored to find out alternative treatment for celiac disease. These targets include exploration of ancient wheat if they are less immunogenic, intra-luminal digestion of gluten using prolylendopeptidases, pretreatment of whole gluten with bacterial-derived peptidase before ingestion; prevention of passage of immunogenic peptides through the tight junctions such as zonulin antagonists, Blocking of HLA-DQ2 to prevent binding of immunogenic peptides, inhibition of transglutaminase 2, immune-modulation, and induction of tolerance to gluten using gluten tolerizing vaccines, use of gluten-sequestering polymers, use of anti-inflammatory drugs (glucocorticoids, budesonides) and anti-cytokines such as anti TNF-α, and anti-interleukin-15. While many of these targets are still in the pre-clinical phase, some of them including zonulin antagonist and endopeptidases have already reached phase II and phase III clinical trials. Furthermore, while these targets appear very exciting; they at best are likely to be used as adjunctive therapy rather than a complete replacement for gluten-free diet. PMID:25705619

    Until a few years ago, celiac disease (CD) was thought to be a rare food intolerance that was confined to childhood and characterized by severe malabsorption and flat intestinal mucosa. Currently, CD is regarded as an autoimmune disorder that is common in the general population (affecting 1 in 100 individuals), with possible onset at any age and with many possible presentations. The identification of CD is challenging because it can begin not only with diarrhea and weight loss but also with atypical gastrointestinal (constipation and recurrent abdominal pain) and extra-intestinal symptoms (anemia, raised transaminases, osteoporosis, recurrent miscarriages, aphthous stomatitis and associated autoimmune disorders), or it could be completely symptomless. Over the last 20 years, the diagnostic accuracy of serology for CD has progressively increased with the development of highly reliable tests, such as the detection of IgA tissue transglutaminase and antiendomysial and IgG antideamidated gliadin peptide antibodies. The routine use of antibody markers has allowed researchers to discover a very high number of ‘borderline' cases, characterized by positive serology and mild intestinal lesions or normal small intestine architecture, which can be classified as potential CD. Therefore, it is evident that the ‘old celiac disease' with flat mucosa is only a part of the spectrum of CD. It is possible that serology could identify CD in its early stages, before the appearance of severe intestinal damage. In cases with a positive serology but with mild or absent intestinal lesions, the detection of HLA-DQ2 and HLA-DQ8 can help reinforce or exclude the diagnosis of gluten sensitivity. PMID:21278763

    Background and Objectives Genome-wide association studies (GWAS) have identified several genetic regions involved in immune-regulatory mechanisms to be associated with celiac disease. Previous GWAS also revealed an over-representation of genes involved in type 2 diabetes and anorexia nervosa associated with celiac disease, suggesting involvement of common metabolic pathways for development of these chronic diseases. The aim of this study was to extend these previous analyses to study the gene expression in the gut from children with active celiac disease. Material and Methods Thirty six target genes involved in type 2 diabetes and four genes associated with anorexia nervosa were investigated for gene expression in small intestinal biopsies from 144 children with celiac disease at median (range) age of 7.4 years (1.6–17.8) and from 154 disease controls at a median (range) age 11.4.years (1.4–18.3). Results A total of eleven of genes were differently expressed in celiac patients compared with disease controls of which CD36, CD38, FOXP1, SELL, PPARA, PPARG, AGT previously associated with type 2 diabetes and AKAP6, NTNG1 with anorexia nervosa remained significant after correction for multiple testing. Conclusion Shared genetic factors involved in celiac disease, type 2 diabetes and anorexia nervosa suggest common underlying molecular pathways for these diseases. PMID:27483138

    We report a case of a 35 year-old-woman who suffered from abdominal pain and weight loss. Asymptomatic celiac disease was discovered and complicated with a MALT Lymphoma in the jejunum. This is an uncommon combination because lymphoma that arises in the presence of enteropathy is commonly from T lymphocytes. Also because it normally appears in patients with long standing celiac disease who report a recrudescence of the abdominal symptoms. PMID:9923102

    Celiac disease (CD) is the world's most common genetic food intolerance disorder. Children with celiac disease cannot tolerate gluten, a storage protein in wheat, rye, and barley. The first recognizable symptom in children is often an oral manifestation, rather than the typical gastrointestinal symptoms. The purpose of this paper is to review the oral and dental manifestations of CD to help pediatric dentists identify and refer atypically symptomatic patients to their pediatricians. PMID:27620516

    The worldwide increase of celiac disease prompted us to assess its prevalence in the Italian general population. The 3483 inhabitants of Campogalliano were tested for immunoglobulin A anti-endomysial antibodies. Twenty subjects showed antibody positivity and duodenal biopsy detected typical mucosal lesions of celiac disease in 17 of them; the remaining three cases had a normal villous architecture, but the finding of increased gamma/delta intraepithelial lymphocytes in all and the heterodimer DQA1*0501, DQB1*0201 in two of them was consistent with potential celiac disease. Only one patient had an overt malabsorption syndrome, characterized by diarrhea, weight loss, and severe weakness. In eight subjects atypical symptoms of celiac disease, such as dyspepsia and depression, were present, whereas the remaining subjects were silent. Celiac disease was more frequent in younger age groups. Our cross-sectional design study demonstrates that celiac disease prevalence in the Italian general population is 4.9 per 1000 (95% CI 2.8-7.8), increasing up to 5.7 per 1000 (95% CI 3.5-8.8) with the inclusion of potential cases.

    A hallmark of active celiac disease (CD), an inflammatory small-bowel enteropathy caused by permanent intolerance to gluten, is cytokine production by intestinal T lymphocytes. Prerequisites for contracting CD are that the individual carries the MHC class II alleles HLA-DQ2 and/or HLA-DQ8 and is exposed to gluten in the diet. Dysbiosis in the resident microbiota has been suggested to be another risk factor for CD. In fact, rod shaped bacteria adhering to the small intestinal mucosa were frequently seen in patients with CD during the “Swedish CD epidemic” and bacterial candidates could later be isolated from patients born during the epidemic suggesting long-lasting changes in the gut microbiota. Interleukin-17A (IL-17A) plays a role in both inflammation and anti-bacterial responses. In active CD IL-17A was produced by both CD8+ T cells (Tc17) and CD4+ T cells (Th17), with intraepithelial Tc17 cells being the dominant producers. Gluten peptides as well as CD associated bacteria induced IL-17A responses in ex vivo challenged biopsies from patients with inactive CD. The IL-17A response was suppressed in patients born during the epidemic when a mixture of CD associated bacteria was added to gluten, while the reverse was the case in patients born after the epidemic. Under these conditions Th17 cells were the dominant producers. Thus Tc17 and Th17 responses to gluten and bacteria seem to pave the way for the chronic disease with interferon-γ-production by intraepithelial Tc1 cells and lamina propria Th1 cells. The CD associated bacteria and the dysbiosis they might cause in the resident microbiota may be a risk factor for CD either by directly influencing the immune responses in the mucosa or by enhancing inflammatory responses to gluten.

    Background: There is an association of celiac disease (CD) with several gastrointestinal illnesses. We aimed to determine the prevalence of CD in patients with inflammatory bowel disease (IBD) to evaluate the value of the routine serological tests for CD in these patients. Materials and Methods: patients with IBD underwent screening test for CD. The screening test was based on IgA anti-tTG antibody evaluated by ELISA method and IgA EMA (endomysial antibody) measured by the indirect immunofluorescence method. Fisher exact and chi-square and t tests were used for data analysis. Results: the study was conducted on 100 patients, with a mean age of 34.74 ± 12.03 (SD) years. The mean simplified Crohn's disease activity index was 90 ± 17 (SE) and the mean colitis activity index was 3.46± 0.96 (SE). Seventeen patients (17%) had IgA anti-tTG antibody levels above the cutoff point (> 20). Thirty-two patients were positive for IgA EMA. IgA EMA was positive in nine IgA anti-tTG positive patients (three patients with Crohn's Disease and six ones with ulcerative colitis). Then, the prevalence of serologic CD was 9% that was higher than that of general population. A significant correlation was found between the results of IgA EMA and those of IgA anti-tTG (P=0.001) whereas Fisher exact test revealed significant difference between frequency distribution of positive and negative results of IgA EMA and IgA anti-tTG in patients with ulcerative colitis and Crohn's disease (P=0). Conclusion: the prevalence of serologic CD in general population in Iran has been reported to be 0.6–0.96%. Then, its prevalence in our sample size was about ten times more than that in general population. PMID:23264789

    Celiac disease represents one of the most frequent chronic inflammatory diseases. In Italy the prevalence among school-age population has been calculated in 1:180 subjects. Along with typical forms of the disease characterized by overt symptoms and signs of malabsorption, many cases are undiagnosed because they are subclinical, atypical or even symptomless. In adults, the disease may present with infertility; in particular celiac disease may be responsible of multiple abortions. These manifestations, whose pathogenesis is unknown, are not related to the severity of the disease; the gluten-free diet strongly ameliorates the fertility. In this paper we have focused the connection between abortion and celiac disease. A better knowledge of this relationship may lead to correctly diagnose and consequently to treat the cause of some cases of abortion, previously labelled as cases of unidentified origin.

    Celiac disease (CD) is an immune-mediated disease characterized by permanent gastrointestinal tract sensitivity to gluten in genetically predisposed individuals. It has varied clinical manifestations, ranging from gastrointestinal to extraintestinal, including neurological, skin, reproductive and psychiatric symptoms, which makes its diagnosis difficult and challenging. Known neurological manifestations of CD include epilepsy with or without occipital calcification, attention deficit hyperactivity disorder and ataxia, headache, neuropathies and behavior disorders. We present the case of a 14-year-old female with headaches and blurred vision for 1 year; she was noted to have papilledema on ophthalmic examination with increased cerebrospinal fluid opening pressure on lumber puncture and was diagnosed as a case of pseudotumor cerebri (PTC). Meanwhile her workup for chronic constipation revealed elevated tissue transglutaminase IgA and antiendomysial IgA antibodies. Upper gastrointestinal endoscopy with duodenal biopsy confirmed the diagnosis of CD. The patient was started on a gluten-free diet, leading to resolution of not only gastrointestinal symptoms but also to almost complete resolution of symptoms of PTC. This report describes the correlation of CD and PTC as its neurological manifestation. PMID:26120302

    Celiac disease (CD) is one of the most common diseases, resulting from both environmental (gluten) and genetic factors [human leukocyte antigen (HLA) and non-HLA genes]. The prevalence of CD has been estimated to approximate 0.5%-1% in different parts of the world. However, the population with diabetes, autoimmune disorder or relatives of CD individuals have even higher risk for the development of CD, at least in part, because of shared HLA typing. Gliadin gains access to the basal surface of the epithelium, and interact directly with the immune system, via both trans- and para-cellular routes. From a diagnostic perspective, symptoms may be viewed as either "typical" or "atypical". In both positive serological screening results suggestive of CD, should lead to small bowel biopsy followed by a favourable clinical and serological response to the gluten-free diet (GFD) to confirm the diagnosis. Positive anti-tissue transglutaminase antibody or anti-endomysial antibody during the clinical course helps to confirm the diagnosis of CD because of their over 99% specificities when small bowel villous atrophy is present on biopsy. Currently, the only treatment available for CD individuals is a strict life-long GFD. A greater understanding of the pathogenesis of CD allows alternative future CD treatments to hydrolyse toxic gliadin peptide, prevent toxic gliadin peptide absorption, blockage of selective deamidation of specific glutamine residues by tissue, restore immune tolerance towards gluten, modulation of immune response to dietary gliadin, and restoration of intestinal architecture.

    Celiac Disease (CD) occurs in patients with Type 1 Diabetes (T1D) ranging the prevalence of 4.4-11.1% versus 0.5% of the general population. The mechanism of association of these two diseases involves a shared genetic background: HLA genotype DR3-DQ2 and DR4-DQ8 are strongly associated with T1D, DR3-DQ2 with CD. The classical severe presentation of CD rarely occurs in T1D patients, but more often patients have few/mild symptoms of CD or are completely asymptomatic (silent CD). In fact diagnosis of CD is regularly performed by means of the screening in T1D patients. The effects of gluten-free diet (GFD) on the growth and T1D metabolic control in CD/T1D patient are controversial. Regarding of the GFD composition, there is a debate on the higher glycaemic index of gluten-free foods respect to gluten-containing foods; furthermore GFD could be poorer of fibers and richer of fat. The adherence to GFD by children with CD-T1D has been reported generally below 50%, lower respect to the 73% of CD patients, a lower compliance being more frequent among asymptomatic patients. The more severe problems of GFD adherence usually occur during adolescence when in GFD non compliant subjects the lowest quality of life is reported. A psychological and educational support should be provided for these patients. PMID:22449104

Both diseases may present the intestinal malabsorption syndrome and similar clinical manifestations that contribute to difficulties with clinical distinction. We describe a report of two patients with initial diagnosis of cystic fibrosis, who were subsequently diagnosed with celiac disease. These case reports emphasize the possibility of false positivity being shown in the sweat test in CD, which may result in delayed diagnosis and inadequate management of this disease. PMID:27552792

    Background Celiac disease has been linked to decreased quality of life and certain mood disorders. The effect of the gluten free diet on these psychological aspects of the disease is still unclear. Objectives The objective of this article is to review the literature on psychological morbidity of celiac disease. Methods We performed a PubMed search for the time period from 1900 until June 1, 2014, to identify papers on psychological aspects of celiac disease looking specifically at quality of life, anxiety, depression and fatigue. Results Anxiety, depression and fatigue are common complaints in patients with untreated celiac disease and contribute to lower quality of life. While aspects of these conditions may improve within a few months after starting a gluten-free diet, some patients continue to suffer from significant psychological morbidity. Psychological symptoms may affect the quality of life and the dietary adherence. Conclusion Health care professionals need to be aware of the ongoing psychological burden of celiac disease in order to support patients with this disease. PMID:25922673

    Celiac disease is an intestinal inflammatory disease that is triggered by gluten in the diet. Patients present with a wide array of symptoms due to malabsorption that include diarrhea, abdominal pain, bloating and weight loss. In women, this disease may have implications on menstrual and reproductive health. The symptom complex includes delayed menarche, early menopause, secondary amenorrhea, infertility, recurrent miscarriages and intrauterine growth restriction. These women benefit from early diagnosis and treatment. Therefore, celiac disease should be considered and screening tests performed on women presenting with menstrual and reproductive problems and treated accordingly. The objective of this article is to review the current literature on celiac disease and its association with the above-mentioned disorders. PMID:20337200

    Recent studies have implicated long noncoding RNAs (lncRNAs) as regulators of many important biological processes. Here we report on the identification and characterization of a lncRNA, lnc13, that harbors a celiac disease-associated haplotype block and represses expression of certain inflammatory genes under homeostatic conditions. Lnc13 regulates gene expression by binding to hnRNPD, a member of a family of ubiquitously expressed heterogeneous nuclear ribonucleoproteins (hnRNPs). Upon stimulation, lnc13 levels are reduced, thereby allowing increased expression of the repressed genes. Lnc13 levels are significantly decreased in small intestinal biopsy samples from patients with celiac disease, which suggests that down-regulation of lnc13 may contribute to the inflammation seen in this disease. Furthermore, the lnc13 disease-associated variant binds hnRNPD less efficiently than its wild-type counterpart, thus helping to explain how these single-nucleotide polymorphisms contribute to celiac disease.

    Celiac disease is a common autoimmune disease triggered by gluten-containing foods (wheat, barley and rye) in genetically predisposed individuals. We present a patient with celiac disease complicated by severe aphthous stomatitis resulting in impairing swallowing, chewing and speaking. This led to weight loss, psychosocial problems as well as inability to perform her work. A variety of topical and systemic medications used resulted in either no improvement or only partial alleviation of the patient’s symptoms. After informed consent, etanercept was initiated and resulted in complete remission of aphthous stomatitis, decrease in arthralgia and fatigue and considerable improvement in her quality of life. The use of newer biological agents for selected and severe manifestations of celiac disease may lead to improved morbidity in these patients, but more studies are needed to determine long-term efficacy as well as safety of these drugs in the mucosal and/or systemic complications of this disease.

    2013-12-01

    Reduced levels of iron, folate, vitamin B12, vitamin D, zinc, and magnesium are common in untreated celiac disease (CD) patients probably due to loss of brush border proteins and enzymes needed for the absorption of these nutrients. In the majority of patients, removal of gluten from the diet leads to histological recovery and normalization of iron, vitamin, and mineral levels. Iron deficiency anemia is the most common extra-intestinal sign of CD and usually resolves with adherence to a gluten-free diet. However, deficiencies of both folate and vitamin B12 may persist in some patients on a gluten-free diet, thus requiring vitamin supplementation to improve subjective health status. Similarly, exclusion of gluten from the diet does not always normalize bone mineral density; in these cases, supplementation of vitamin D and calcium is recommended. Resolution of mucosal inflammation may not be sufficient to abrogate magnesium deficiency. Since gluten-free cereal products have a lower magnesium content as compared with gluten-containing counterparts, a magnesium-enriched diet should be encouraged in CD patients. In this article we discuss the frequency and clinical relevance of nutrient deficiency in CD and whether and when nutrient supplementation is needed. PMID:24195595

    For many years irritable bowel syndrome (IBS) and celiac disease (CD) have been considered 2 completely separate entities, with CD being clearly related to a permanent gluten intolerance and IBS having no relation with gluten ingestion. However IBS and CD symptoms may be indistinguishable, especially when diarrhea, bloating or abdominal pain predominate. In the last decade several studies have shown that the separation between CD and IBS is not so clear. Thus, some patients who have been diagnosed of IBS suffer in fact from CD. In addition, it seems that there is a group of patients who, without having CD, suffer gluten intolerance that cause them digestive symptoms similar to those of IBS. Gluten sensitivity is defined as the spectrum of morphological, immunological and functional abnormalities that respond to a gluten-free diet. This concept includes histological, immunological and clinical manifestations in the absence of evident morphological abnormalities. Therefore, it is mandatory to establish in a scientific way in which patients a gluten-free diet will be beneficial as well as when this is not justified. PMID:24029448

    (/sup 51/Cr)EDTA was used as a probe molecule to assess intestinal permeability in 7 healthy control adults, 11 control children, 17 children with Crohn's disease, and 6 children with untreated celiac disease. After subjects fasted overnight, 75 kBq/kg (= 2 microCi/kg) /sup 51/Cr-labeled EDTA was given by mouth; 24-h urinary excretion of (/sup 51/Cr)EDTA was measured and expressed as a percentage of the total oral dose. Mean and SD were as follows: control adults 1.47 +/- 0.62, control children 1.59 +/- 0.55, and patients with Crohn's disease or celiac disease 5.35 +/- 1.94. The difference between control children and patients was statistically significant (p less than 0.001). These results show that intestinal permeability to (/sup 51/Cr)EDTA is increased among children with active or inactive Crohn's disease affecting small bowel only or small bowel and colon, and with untreated celiac disease. The (/sup 51/Cr)EDTA permeability test could facilitate the decision to perform more extensive investigations in children suspected of small bowel disease who have atypical or poor clinical and biological symptomatology.

    Scale invariant texture recognition methods are applied for the computer assisted diagnosis of celiac disease. In particular, emphasis is given to techniques enhancing the scale invariance of multi-scale and multi-orientation wavelet transforms and methods based on fractal analysis. After fine-tuning to specific properties of our celiac disease imagery database, which consists of endoscopic images of the duodenum, some scale invariant (and often even viewpoint invariant) methods provide classification results improving the current state of the art. However, not each of the investigated scale invariant methods is applicable successfully to our dataset. Therefore, the scale invariance of the employed approaches is explicitly assessed and it is found that many of the analyzed methods are not as scale invariant as they theoretically should be. Results imply that scale invariance is not a key-feature required for successful classification of our celiac disease dataset. PMID:23481171

    Background Isotretinoin (13-cis retinoic acid) is a metabolite of vitamin A and has anti-inflammatory and immunoregulatory effects; however, a recent publication by DePaolo et al. demonstrated that in the presence of IL-15, retinoic acid can act as an adjuvant and promote inflammation against dietary proteins. Objective To evaluate the risk of overt and latent celiac disease (CD) among users of isotretinoin. Material and Methods Medical records of patients from 1995 to 2011 who had a mention of isotretinoin in their records (N = 8393) were searched for CD diagnosis using ICD-09CM codes. Isotretinoin exposure was compared across overt CD patients and their age- and gender-matched controls from the same pool. To evaluate the risk of latent CD with isotretinoin exposure, patients were overlapped with a community-based list of patients with waste serum samples that were tested for CD serology, excluding those with overt CD (2006–2011). Isotretinoin exposure was defined as the use of isotretinoin prior to CD diagnosis or serology. Results Of 8393 patients, 25 had a confirmed CD diagnosis. Compared to matched controls (N = 75), isotretinoin exposure was not significantly different between overt CD patients versus controls (36% versus 39%, respectively; P = 0.712). Likewise, latent CD defined as positive serology was not statistically different between isotretinoin exposed (N = 506) versus non-exposed (N = 571) groups (1.8% versus 1.4%, respectively; P = 0.474). Conclusions There was no association between isotretinoin use and risk of either overt or latent CD. PMID:26287738

    HLA molecular typing for celiac disease (CD) is a genetic test with a high negative predictive value. The aim of this study is to explore knowledge of and attitudes towards genetic testing (GT). A 25-item questionnaire was developed by a multidisciplinary team and distributed to members of CD support groups across the United States. Respondents (n=1835) were mainly female (88 %), married (76 %), and college-educated (55 %), with a median age range of 31–50 years. Those who were married (82 vs 75 %, p=0.002), had children (82 vs 74%, p<0.001), and had pursued education beyond high school (81 vs 68 %, p=0.004) were more likely to be aware of the availability of GT. On multivariable analysis, adjusting for age, sex, education, marital status, region of residence, and having children, college-education (OR 2.05, 95 % CI: 1.33–3.16) and having children (OR 1.56, 95 % CI: 1.15–2.11) remained significant predictors of GT awareness. A majority of patients with a personal or family history of CD planned GT for their children, and the most common concerns regarding GT were cost and impact on health care and/or insurance. In conclusion, awareness of GT is high among CD support group members. Efforts should be made to increase knowledge of GT in those with a lower educational level, and healthcare professionals should attempt to address concerns regarding GT cost and the impact of results on health care and insurance status.

    Abstract Objective. The prevalence of celiac disease (CD) as recorded in the Danish National Patient Registry is ∼50/100,000 persons. This is much lower than the reported prevalence of CD in other Nordic countries and underdiagnosis is suspected. Our aim was to estimate the prevalence of CD in a population-based study of Danish adults. Methods. A total of 2297 adults aged 24–76 years living in the southwestern part of Copenhagen were screened for CD by immunoglobulin (Ig)A and IgG antibodies to transglutaminases and deamidated gliadin. IgA/IgG-positive participants were invited to a clinical evaluation, including biopsies, by a gastroenterologist. Results. Of the invited 56 participants, 40 underwent a full clinical evaluation and 8 persons were diagnosed with CD; 2 of the 16 persons, who did not complete the clinical evaluation, were considered by experts to have probable CD. None of the above 56 participants had a known history of CD or a recorded diagnosis of CD in National Patient Registry. By combining cases of biopsy-proven CD (n = 8), probable CD (n = 2), and registry-recorded CD (n = 1), the prevalence of CD was estimated to be 479/100,000 (11/2297) persons (95% CI: 197–761). Conclusion. In this general adult population, the prevalence of CD as estimated by screening and clinical evaluation was 10 times higher than the registry-based prevalence of CD. Of 11 participants diagnosed with CD in our screening study, 10 were unaware of the diagnosis prior to the study. Thus, our study suggests that CD is markedly underdiagnosed in Danish adults.

    We report the case of a two-year-five-month-old child who underwent screening for celiac disease due to strong familiarity. During the first observation body weight and height were at 25th and 50th centile for gender and age. Physical examination did not reveal any sign of disease. Blood tests showed increased transaminases levels and antibodies research showed: tTG IgA: 100 UI/ml, tTG IgG: 36,6 UI/ml, EMA IgA: positive. HLA study revealed homozygous allelic combination DRB1*07;DQA102:01; DQB1* 02:02 with presence of a double copy of beta chain in the composition of the  DQ2 heterodymer. Biopsy with histological examination did find neither mucosal alteration  nor lymphocytic infiltrates (Marsh 0). During follow up with free diet the patient remained asymptomatic and all antibody titers decreased up to normalization. According to ESPGHAN guidelines the finding of hypertransaminasemia as sign of celiac hepatic inflammation, a more than 10-fold increase of tTG IgA and a high-risk HLA would permit diagnosis of celiac disease but histological examination done due to mismatch between paucity of clinical sings and a "multiple risk combination" excluded it, allowing diagnosis of potential celiac disease.  We believe that this case is interesting because of its being in contrast with current literature data that suggest a linear relationship between antibodies levels and histological damage with tTG IgA at the upper reference range in case of potential celiac disease. According to guidelines we could have avoided intestinal biopsy but we would have considered as celiac a patient who is maybe just potentially affected. PMID:27163902

    Objectives. Studies have suggested a correlation between untreated celiac disease and risk for other autoimmune diseases. We investigated the prevalence of thyroid autoimmunity in 12-year-old children (i) with symptomatic celiac disease diagnosed and treated with a gluten-free diet, (ii) with screening-detected untreated celiac disease, and (iii) without celiac disease. Methods. Blood samples from 12632 children were collected. All celiac disease cases, previously diagnosed and newly screening-detected, were identified. Per case, 4 referents were matched. Blood samples were analyzed for autoantibodies against thyroid peroxidase (TPOAb). The cut-off value for TPO positivity was set to 100 U/mL. Results. Altogether, 335 celiac disease cases were found. In the entire celiac disease group, 7.2% (24/335) had elevated titers of TPOAb compared to 2.8% (48/1695) of the referents. Among the previously diagnosed celiac disease cases, 7.5% (7/93, OR 2.8, 95% CI 1.2–6.4) was TPOAb positive and among screening-detected cases, 7.0% (17/242, OR 2.6, 95% CI 1.5–4.6) was TPOAb positive. Conclusion. Children with celiac disease showed a higher prevalence of thyroid autoimmunity. We could not confirm the hypothesis that untreated celiac disease is associated with increased risk of developing thyroid autoimmunity. Early initiation of celiac disease treatment might not lower the risk for other autoimmune diseases. PMID:24592326

    Objectives: To assess knowledge of celiac disease among medical professionals (physicians). Methods: We conducted a cross-sectional survey of hospital-based medical staff in primary, secondary, and tertiary care public, and private hospitals in Riyadh, Saudi Arabia (KSA). We carried out the study between January 2013 and January 2104 at King Khalid University Hospital, King Saud University, Riyadh, KSA. A pretested questionnaire was distributed to the potential participants. A scoring system was used to classify the level of knowledge of participants into 3 categories: poor, fair, and good. Results: A total of 109 physicians completed the survey and of these participants, 86.3% were from public hospitals, and 13.7% from private hospitals; 58.7% were males. Of the physicians, 19.2% had poor knowledge. Interns and residents had fair to good knowledge, but registrars, specialists, and even the consultants were less knowledgeable of celiac disease. Conclusion: Knowledge of celiac disease is poor among a significant number of physicians including consultants, which can potentially lead to delays in diagnosis. Educational programs need to be developed to improve awareness of celiac disease in the health care profession. PMID:25987121

    The association of epilepsy, occipital calcifications, and celiac disease has been recognized as a distinct syndrome. The objective of this study was to present the clinical, electrophysiologic, and neuroradiologic features in a series of patients with this syndrome. Thirty-two patients with the constellation of epilepsy, occipital calcifications, and celiac disease were identified in our epilepsy clinic. The mean age was 11 years and the mean length of follow-up was 7.4 years. The 1990 criteria of the European Society of Pediatric Gastroenterology and Nutrition were used to diagnose celiac disease. The Kruskal-Wallis statistics test was employed with a signficance of P < .05. Thirty-one patients had partial seizures, 21 of them with symptoms related to the occipital lobe. In most patients, the epilepsy was controlled or the seizures were sporadic. Three developed severe epilepsy. Occipital calcifications were present in all cases. Computed tomography in 7 patients showed hypodense areas in the white matter around calcifications, which decreased or disappeared after a period of gluten-free diet in 3 patients. A favorable outcome of epilepsy was detected in patients with the earliest dietary therapy. This study presents the largest series of children with this syndrome outside Italy. White-matter hypodensities surrounding calcifications are rarely reported. A prompt diagnosis of celiac disease might improve the evolution of the epilepsy and may improve cognitive status.

    Objective: This study has examined the prevalence of celiac disease in Turkish children with idiopathic epilepsy. Methods: Children with idiopathic epilepsy were screened for celiac disease using the IgA anti-tissue transglutaminase antibody and compared with the healthy control group in order to find the association of celiac disease (CD) with idiopathic epilepsy. Upper gastrointestinal endoscopy and small intestinal biopsies were offered to all antibody-positive patients. Findings : A total of 214 children with the diagnosis of idiopathic epilepsy and 166 healthy children as control group were studied. Of the patients recruited, 55.1% had generalized epilepsy, and 44.9% had partial epilepsy. In 33 patients with partial epilepsy, electroclinical features were consistent with a diagnosis of childhood partial epilepsy with occipital paroxysms (CPEO). Two of 33 patients with CPEO had positive IgA anti-tissue transglutaminase antibodies in serology. Pathological examination of small intestinal biopsy specimens showed total villous atrophy in both of them. The prevalence of celiac disease among children with idiopathic epilepsy and CPEO was 0.9% and 6%, respectively. Conclusion: The results of the present study revealed that prevalence of CD is increased in children with epilepsy. On the other hand, as high as 6% prevalence of CD among patients with CPEO found in this study should be kept in mind and the clinicians should be aware of this association. PMID:25562021

    The celiac disease is traditionally viewed as the children's disease with a typical form accompanied mainly by intestinal symptoms and malabsorption. This opinion is still generally accepted by the medical community. Findings based on the area-wide screening show that the prevalence has risen from the original 1 : 1 000-1 500 to 1 : 70-550. The average prevalence in the western countries is nearly 1 : 100. The prevalence of the celiac disease in the Czech republic is estimated to be approximately 1 : 200-250. It means that the number of people in the Czech republic who are likely to be affected is about 40,000-50,000 people. Currently only 10-15% of the total number of the ill people are diagnosed and monitored. Adult patients represent the main diagnostic problem because their clinical pictures are individual and the main symptoms are atypical (nonenteral). These are anaemia (mainly sideropnic), early/premature osteoporosis, herpetiformic (Duhring) dermatitis, polyneurititis, ataxia, depression, behavioural disorders, menstrual cycle disorders and infertility. Therefore our attention is currently focused on the screening of these groups of subjects. The purpose of our study was to check the frequency of the celiac disease with patients with diagnosed osteoporosis and osteopenia. In our study we have confirmed the assumption that the prevalence ofthe celiac disease in the group of subjects was 1 : 50, which means that 2.2% of patients with osteoporosis and osteopenia are affected by celiac sprue and therefore screening examination of these patients with the subsequent causal treatment (gluten-free diet) is recommended.

    Recent findings demonstrate the common genetic basis for many immune-mediated diseases, and consequently, the partially shared pathogenesis. We collected these findings and reviewed the extension of these overlaps to other disease characteristics. Two autoimmune diseases were selected that also share the specific target organ, the bowel. The etiology and immunopathogenesis of both conditions characterized by chronic intestinal inflammation, inflammatory bowel disease (IBD) and celiac disease (CeD), are not completely understood. Both are complex diseases with genetics and environment contributing to dysregulation of innate and adaptive immune responses, leading to chronic inflammation and disease. CeD constitutes a particular disease because the main environmental and genetic triggers are largely known. IBD comprises two main clinical forms, Crohn’s disease and ulcerative colitis, which most likely involve a complex interplay between some components of the commensal microbiota and other environmental factors in their origin. These multifactorial diseases encompass a broad spectrum of clinical phenotypes and ages of onset, although the clinical presentation often differs depending on childhood or adult onset, with greater heterogeneity commonly observed in adults.

    We report on a patient who was diagnosed six years before with celiac disease, with a current combined problem of asplenism, mesenteric cysts and elevated liver function tests. The implications of splenic atrophy mimic those of post-splenectomy patients. Mesenteric lymph node cavitation is a rare complication of celiac disease that is most often associated with splenic atrophy. The pathogenesis is unknown. The clinical implications of the cavitated mesenteric lymph nodes are unclear. The association of celiac disease with liver disease was reported many years ago, but only recently these associations have been more clearly defined. Liver involvement shows a clinical spectrum varying from nonspecific reactive hepatitis, chronic active hepatitis, steatohepatitis to frank cirrhosis. Associations with autoimmune hepatitis, autoimmune cholangitis, primary biliary cirrhosis and primary sclerosing cholangitis have been described. In our patient, we found no obvious cause for the necrotizing hepatitis and the negative auto-antibodies made it impossible to firmly establish the diagnosis of autoimmune hepatitis. The causal relationship with celiac disease, if any, remains unproven. PMID:18720941

    A magneto immunofluorescence assay for the detection of anti-transglutaminase antibodies (ATG2) in celiac disease was developed. The ATG2 were recognized by transglutaminase enzyme immobilized on the magnetic beads and then the immunological reaction was revealed by antibodies labeled with peroxidase. The fluorescent response of the enzymatic reaction with o-phenylenediamine and H2O2 as substrates was correlated with anti-transglutaminase titer, showing EC50 and LOD values of 1:11,600 and 1:74,500 of antibody titers, respectively. A total number of 29 sera samples from clinically confirmed cases of celiac disease and 19 negative control samples were tested by the novel magneto immunofluorescence assay. The data were submitted to the receiver-operating characteristic plot (ROC) analysis which indicated that 8.1 U was the most effective cut-off value to discriminate correctly between celiac and non-celiac patients. The immunofluorescence assay exhibited a sensitivity of 96.6%, a specificity of 89.5% and an efficiency 93.8% compared with the commercial optical ELISA kit. PMID:24070488

    Celiac disease (CD) is an immune-mediated enteropathy triggered by the ingestion of cereal gluten proteins. This disorder is associated with imbalances in the gut microbiota composition that could be involved in the pathogenesis of CD. The aim of this study was to characterize the composition and diversity of the cultivable duodenal mucosa-associated bacteria of CD patients and control children. Duodenal biopsy specimens from patients with active disease on a gluten-containing diet (n = 32), patients with nonactive disease after adherence to a gluten-free diet (n = 17), and controls (n = 8) were homogenized and plated on plate count agar, Wilkins-Chalgren agar, brain heart agar, or yeast, Casitone, and fatty acid agar. The isolates were identified by partial 16S rRNA gene sequencing. Renyi diversity profiles showed the highest diversity values for active CD patients, followed by nonactive CD patients and control individuals. Members of the phylum Proteobacteria were more abundant in patients with active CD than in the other child groups, while those of the phylum Firmicutes were less abundant. Members of the families Enterobacteriaceae and Staphylococcaceae, particularly the species Klebsiella oxytoca, Staphylococcus epidermidis, and Staphylococcus pasteuri, were more abundant in patients with active disease than in controls. In contrast, members of the family Streptococcaceae were less abundant in patients with active CD than in controls. Furthermore, isolates of the Streptococcus anginosus and Streptococcus mutans groups were more abundant in controls than in both CD patient groups, regardless of inflammatory status. The findings indicated that the disease is associated with the overgrowth of possible pathobionts that exclude symbionts or commensals that are characteristic of the healthy small intestinal microbiota.

    Celiac disease (CD) is a common CD4(+) T cell mediated enteropathy driven by gluten in wheat, rye, and barley. Whilst clinical feeding studies generally support the safety of oats ingestion in CD, the avenin protein from oats can stimulate intestinal gluten-reactive T cells isolated from some CD patients in vitro. Our objective was to establish whether ingestion of oats or other grains toxic in CD stimulate an avenin-specific T cell response in vivo. We fed participants a meal of oats (100 g/day over 3 days) to measure the in vivo polyclonal avenin-specific T cell responses to peptides contained within comprehensive avenin peptide libraries in 73 HLA-DQ2.5(+) CD patients. Grain cross-reactivity was investigated using oral challenge with wheat, barley, and rye. Avenin-specific responses were observed in 6/73 HLA-DQ2.5(+) CD patients (8%), against four closely related peptides. Oral barley challenge efficiently induced cross-reactive avenin/hordein-specific T cells in most CD patients, whereas wheat or rye challenge did not. In vitro, immunogenic avenin peptides were susceptible to digestive endopeptidases and showed weak HLA-DQ2.5 binding stability. Our findings indicate that CD patients possess T cells capable of responding to immuno-dominant hordein epitopes and homologous avenin peptides ex vivo, but the frequency and consistency of these T cells in blood is substantially higher after oral challenge with barley compared to oats. The low rates of T cell activation after a substantial oats challenge (100 g/d) suggests that doses of oats commonly consumed are insufficient to cause clinical relapse, and supports the safety of oats demonstrated in long-term feeding studies.

    2015-01-01

    Regulation of gut motility is complex and involves neuromuscular, immune and environmental mechanisms. It is well established that patients with celiac disease (CD) often display gut dysmotility. Studies have shown the presence of disturbed esophageal motility, altered gastric emptying, and dysmotility of the small intestine, gallbladder and colon in untreated CD. Most of these motor abnormalities resolve after a strict gluten-free diet, suggesting that mechanisms related to the inflammatory condition and disease process are responsible for the motor dysfunction. Motility abnormalities are also a hallmark of functional bowel disorders such as irritable bowel syndrome (IBS), where it has been proposed as underlying mechanism for symptom generation (diarrhea, constipation, bloating). Non-celiac gluten sensitivity (NCGS) is a poorly defined entity, mostly self-diagnosed, that presents clinically with IBS symptoms in the absence of specific celiac markers. Patients with NCGS are believed to react symptomatically to wheat components, and some studies have proposed the presence of low-grade inflammation in these patients. There is little information regarding the functional characterization of these patients before and after a gluten-free diet. A study suggested the presence of altered gastrointestinal transit in NCGS patients who also have a high prevalence of nonspecific anti-gliadin antibodies. Results of an ongoing clinical study in NCGS patients with positive anti-gliadin antibodies before and after a gluten-free diet will be discussed. Elucidating the mechanisms for symptom generation in NCGS patients is important to find new therapeutic alternatives to the burden of imposing a strict gluten-free diet in patients who do not have CD.

    Background/Aim. Reflux symptoms (RS) are common in patients with celiac disease (CD), a chronic enteropathy that affects primarily the small intestine. We evaluated mucosal integrity and motility of the lower esophagus as mechanisms contributing to RS generation in patients with CD. Methods. We enrolled newly diagnosed CD patients with and without RS, nonceliac patients with classical reflux disease (GERD), and controls (without RS). Endoscopic biopsies from the distal esophagus were assessed for dilated intercellular space (DIS) by light microscopy and electron microscopy. Tight junction (TJ) mRNA proteins expression for zonula occludens-1 (ZO-1) and claudin-2 and claudin-3 (CLDN-2; CLDN-3) was determined using qRT-PCR. Results. DIS scores were higher in patients with active CD than in controls, but similar to GERD patients. The altered DIS was found even in CD patients without RS and normalized after one year of a gluten-free diet. CD patients with and without RS had lower expression of ZO-1 than controls. The expression of CLDN-2 and CLDN-3 was similar in CD and GERD patients. Conclusions. Our study shows that patients with active CD have altered esophageal mucosal integrity, independently of the presence of RS. The altered expression of ZO-1 may underlie loss of TJ integrity in the esophageal mucosa and may contribute to RS generation. PMID:27446827

It occurs as an inflammatory condition with destruction of the normal architecture of villi on consumption of gluten and related protein products found in wheat, barley and rye. However, the exact pathogenesis is not yet fully understood. A gluten-free diet remains the main modality of therapy to date. While some patients continue to have symptoms even on a gluten-free diet, adherence to this diet is also difficult, especially for the children. Hence, there is continued interest in novel methods of therapy and the current research focus is on the promising novel non-dietary modalities of treatment. Here, we critically reviewed the existing literature regarding the pathogenesis of celiac disease in children including the role of in-utero exposure leading to neonatal and infant sensitization and its application for the development of new therapeutic approaches for these patients.

    Non-celiac non-wheat allergy wheat sensitivity is regarded as discrete glutensensitivity diagnosed after the exclusion of celiac disease and wheat allergy. Due to the absence of reliable biomarkers no exact prevalence rates are known and estimations range between 0,5-6 %. Soon after ingestion of wheat, patients complain of intestinal symptoms mainly bloating, abdominal pain, diarrhea or nausea which improve fast under glutenfree diet. Often extraintestinal manifestation as tiredness, muscle or joint pain, headache and depression are reported. Actually, there are no serological markers and no intestinal mucosal damage was found in patients. The underlying mechanism of the disease is completely unknown and beside of gluten other wheat proteins as well as amylase-trypsin-inhibitor or short chain sugars are discussed as triggers. In addition, the involvement of the intestinal microbiome in pathology of glutensensitivity must be considered. PMID:26536646

    Collagenous sprue is a rare disease that goes with persistent diarrhea, weight loss and bad absortion, because it affects the small intestine, mainly duodenum and proximal jejunum. Diagnosis is made by having clinical signs and histological proof of atrophy and subepitelial deposit of collagenous material. Its etiology is not known completely, it is proposed that the origin is autoimmune because its relationship with celiac disease. Also there is a proposal that is a celiac evolution to gluten free diet. Is because this is not clear that we present a case of a patient with bad absorptive diarrhea and a clinical expression of collagenous sprue, that had a great clinical response to corticosteroids with home parenteral nutrition center.

    Introduction: Celiac disease (CD) is a highly prevalent autoimmune disease. The symptoms of CD are varied and atypical, with many patients having no gastrointestinal symptoms. Metabolic bone disease (MBD) is a less recognized manifestation of CD associated with spectrum of musculoskeletal signs and symptoms, viz. bone pains, proximal muscle weakness, osteopenia, osteoporosis, and fracture. We here report five patients who presented with severe MBD as the only manifestation of CD. Materials and Methods: Records of 825 patients of CD diagnosed during 2002–2010 were retrospectively analyzed for clinical features, risk factors, signs, biochemical, and radiological parameters. Results: We were able to identify five patients (0.6%) of CD who had monosymptomatic presentation with musculoskeletal symptoms and signs in the form of bone pains, proximal myopathy, and fragility fractures without any gastrointestinal manifestation. All the five patients had severe MBD in the form of osteopenia, osteoporosis, and fragility fractures. Four of the five patients had additional risk factors such as antiepileptic drugs, chronic alcohol consumption, malnutrition, and associated vitamin D deficiency which might have contributed to the severity of MBD. Conclusion: Severe metabolic disease as the only presentation of CD is rare. Patients show significant improvement in clinical, biochemical, and radiological parameters with gluten-free diet, calcium, and vitamin D supplementation. CD should be looked for routinely in patients presenting with unexplained MBD. PMID:23087864

  14. Barriers impeding serologic screening for celiac disease in clinically high-prevalence populations

    PubMed Central

    2014-01-01

    Background Celiac disease is present in ~1% of the general population in the United States and Europe. Despite the availability of inexpensive serologic screening tests, ~85% of individuals with celiac disease remain undiagnosed and there is an average delay in diagnosis of symptomatic individuals with celiac disease that ranges from ~5.8-11 years. This delay is often attributed to the use of a case-based approach for detection rather than general population screening for celiac disease, and deficiencies at the level of health care professionals. This study aimed to assess if patient-centered barriers have a role in impeding serologic screening for celiac disease in individuals from populations that are clinically at an increased risk for celiac disease. Methods 119 adults meeting study inclusion criteria for being at a higher risk for celiac disease were recruited from the general population. Participants completed a survey/questionnaire at the William K. Warren Medical Research Center for Celiac Disease that addressed demographic information, celiac disease related symptoms (gastrointestinal and extraintestinal), family history, co-morbid diseases and conditions associated with celiac disease, and patient-centered barriers to screening for celiac disease. All participants underwent serologic screening for celiac disease using the IgA tissue transglutaminase antibody (IgA tTG) and, if positive, testing for IgA anti-endomysial antibody (IgA EMA) as a confirmatory test. Results Two barriers to serologic testing were significant across the participant pool. These were participants not knowing they were at risk for celiac disease before learning of the study, and participants not knowing where to get tested for celiac disease. Among participants with incomes less than $25,000/year and those less than the median age, not having a doctor to order the test was a significant barrier, and this strongly correlated with not having health insurance.

    Celiac disease is the most common oral intolerance in Western countries. It results from an immune response towards gluten proteins from certain cereals in genetically predisposed individuals (HLA-DQ2 and/or HLA-DQ8). Its pathogenesis involves the adaptive (HLA molecules, transglutaminase 2, dendritic cells, and CD4(+) T-cells) and the innate immunity with an IL-15-mediated response elicited in the intraepithelial compartment. At present, the only treatment is a permanent strict gluten-free diet (GFD). Multidisciplinary studies have provided a deeper insight of the genetic and immunological factors and their interaction with the microbiota in the pathogenesis of the disease. Similarly, a better understanding of the composition of the toxic gluten peptides has improved the ways to detect them in food and drinks and how to monitor GFD compliance via non-invasive approaches. This review, therefore, addresses the major findings obtained in the last few years including the re-discovery of non-celiac gluten sensitivity. PMID:27216895

    AIM: To investigate whether performing immunohistochemical CD3 staining, in order to improve the detection of intra-epithelial lymphocytosis, has an additional value in the histological diagnosis of celiac disease. METHODS: Biopsies obtained from 159 children were stained by hematoxylin and eosin (HE) and evaluated using the Marsh classification. CD3 staining was subsequently evaluated separately and independently. RESULTS: Differences in evaluation between the routine HE sections and CD3 staining were present in 20 (12.6%) cases. In 10 (6.3%) patients the diagnosis of celiac disease (Marsh II and III) changed on examination of CD3 staining: in 9 cases, celiac disease had initially been missed on the HE sections, while 1 patient had been over-diagnosed on the routine sections. In all patients, the final diagnosis based on CD3 staining, was concordant with serological results, which was not found previously. In the other 10 (12.3%) patients, the detection of sole intra-epithelial lymphocytosis (Marsh I) improved. Nine patients were found to have Marsh I on CD3 sections, which had been missed on routine sections. Interestingly, the only patient with negative serology had Giardiasis. Finally, in 1 patient with negative serology, in whom Marsh I was suspected on HE sections, this diagnosis was withdrawn after evaluation of the CD3 sections. CONCLUSION: Staining for CD3 has an additional value in the histological detection of celiac disease lesions, and CD3 staining should be performed when there is a discrepancy between serology and the diagnosis made on HE sections.

    2012-01-01

    Celiac disease or gluten sensitivity may initially present as one or more neurological signs and/or symptoms. On the other hand, it may be associated with or complicated by neurological manifestations. Neurological presentations are rare in children but as many as 36% of adult patients present with neurological changes. With severe malnutrition after progression of celiac disease, different vitamin deficiencies may develop. Such problems can in turn overlap with previous neurological abnormalities including ataxia, epilepsy, neuropathy, dementia, and cognitive disorders. In this study, we aimed to review the neurological aspects of celiac disease. Early diagnosis and treatment could prevent related disability in patients with celiac disease. PMID:24250863

    Celiac disease is a multisystem immune-mediated disorder caused by exposure to dietary gluten in genetically predisposed individuals. The clinical presentation is characterized by a multitude and diversity of symptoms and complications. The coexistence of celiac disease with other autoimmune disorders has been established, most frequently with type 1 diabetes mellitus and autoimmune thyroiditis. The association of celiac disease with immune-mediated hematologic conditions has been rarely reported. This case study describes a pair of identical twin sisters with celiac disease associated with Evans syndrome in one sibling, and with isolated immune thrombocytopenia in the other. PMID:27312169

    An old saying states that ‘’children are not little adults” and this certainly holds true for celiac disease, as there are many peculiar aspects regarding its epidemiology, diagnosis, clinical presentations, associated diseases, and response to treatment in pediatric compared to adult populations, to such an extent that it merits a description of its own. In fact, contrary to the past when it was thought that celiac disease was a disorder predominantly affecting childhood and characterized by a malabsorption syndrome, nowadays it is well recognized that it affects also adult and elderly people with an impressive variability of clinical presentation. In general, the clinical guidelines for diagnosis recommend starting with specific serologic testing in all suspected subjects, including those suffering from extraintestinal related conditions, and performing upper endoscopy with appropriate biopsy sampling of duodenal mucosa in case of positivity. The latter may be omitted in young patients showing high titers of anti-transglutaminase antibodies. The subsequent management of a celiac patient differs substantially depending on the age at diagnosis and should be based on the important consideration that this is a lifelong condition.

    The treatment of celiac disease is a strict adherence to a gluten-free diet for life. In the past, oats were considered to be toxic to individuals with celiac disease and were not allowed in a gluten-free diet. However, recent evidence suggests that oats that are pure and uncontaminated with other gluten-containing grains, if taken in limited quantities, are safe for most individuals with celiac disease. For adults, up to 70 g (1/2 to 3/4 cup) of oats per day and for children, up to 25 g (1/4 cup) per day are safe to consume. These oats and oat products must fulfill the standards for a gluten-free diet set by the Canadian Food Inspection Agency and Health Canada. The Canadian Celiac Association, in consultation with Health Canada, Agriculture & Agri-Food Canada and the Canadian Food Inspection Agency, has established requirements for growing, processing, and purity testing and labelling of pure oats. These strategies have led to the production of pure, uncontaminated oats for the first time in Canada. Oats and oat products that are safe for consumption by individuals with celiac disease and dermatitis herpetiformis are now commercially available in Canada. PMID:17948135

    Celiac disease is an autoimmune disorder induced by dietary gluten in genetically predisposed individuals. It has a prevalence of ∼1% in many populations worldwide. New diagnoses have increased substantially, due to increased awareness, better diagnostic tools, and probable, real increases in incidence. The breadth of recognized clinical presentations continues to expand, making the disorder highly relevant to all physicians. Newer diagnostic tools, including serologic tests for antibodies against tissue transglutaminase (tTG) and deamidated gliadin peptide, greatly facilitate diagnosis. Tests for celiac-permissive HLA DQ2 and DQ8 molecules are useful in defined clinical situations. Celiac disease is diagnosed by histopathologic examination of duodenal biopsies. However, according to recent controversial guidelines, a diagnosis can be made without biopsy in certain circumstances, especially for children. Symptoms, mortality, and risk for malignancy can each be reduced by adherence to a gluten-free diet. This treatment is a challenge, however, as the diet is expensive, socially isolating, and not always effective in controlling symptoms or intestinal damage. Hence, there is increasing interest in developing non-dietary therapies. PMID:25662623

    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. PMID:27547052

    Celiac disease is associated with decreased bone density, but there are conflicting data regarding fracture risk. We determined the fracture incidence relative to matched controls in a population-based cohort with celiac disease before and after diagnosis. Olmsted County residents with celiac disease (n = 83) diagnosed between 1950 and 2002 were compared with 166 gender and age matched controls. Fracture histories were ascertained from each subject's medical records. Celiac disease is linked to an increased fracture risk before and after diagnosis. Before the index date, cases had a fracture rate twice that of controls (CI: 1.0-3.9, P = 0.045) and 2.5-fold greater after the index date (CI: 1.1-5.6, P = 0.026). Appendicular and axial fractures were 2.5 (CI: 0.9-6.5) and 3.2 times more likely (CI: 1.0-10.5) after the index date. These observations support a rationale for earlier detection of celiac disease, and active management of bone disease before bone effects have occurred, to reduce the persistent risk of fractures.

    Aim: the aim of this study was to investigate the necessity of screening for celiac disease in idiopathic osteoporotic patients. Background: Osteopenia and osteoporosis are well-known and prevalent complications of celiac disease. However, the relative prevalence of celiac disease among osteoporotic populations is not known, and the benefit of screening for celiac disease among the osteoporotic population remains controversial. Patients and methods: We evaluated a total of 560 individuals, 460 with osteoporosis and 100 healthy subjects, from the rheumatology clinic in Imam Khomeini and Shariati hospital by IgA anti-tissue transglutaminase (anti-tTG) for celiac disease. Then individuals with positive serologic test underwent upper GI Endoscopy & 2nd part duodenum biopsies. The clinical findings were evaluated in both groups and were compared with each other. Results: Five (1.08%) of 460 patients with osteoporosis and 1 (1%) of 100 subjects without osteoporosis had celiac disease by positive serologic & pathology results. Three patients with positive serology & pathology results were female. All patients in osteoporotic group had at least one other symptom of celiac disease. Two of them had anemia and others had chronic abdominal pain, recurrent oral aphtous lesion & chronic bloating. Conclusion: In the present study, the prevalence of celiac disease in osteoporotic patients is not high enough to justify recommendation for serologic screening of celiac disease in all patients with idiopathic osteoporosis; but in osteoporotic patients with other celiac or gastrointestinal symptoms and signs, for example iron deficiency anemia, chronic dyspepsia and bloating, constipation or diarrhea and recurrent aphtous lesions, it is necessary to evaluate for celiac disease.

    Celiac disease is emerging in India and has become a public health problem. Almost 6-8 million Indians are estimated to have celiac disease. While there is a large pool of patients with celiac disease in India, until now, only a fraction of them have been diagnosed. With increasing awareness about celiac disease amongst health care providers and the general population, a massive increase in the number of patients with celiac disease is expected now and in the subsequent decade in India. While the number of patients with celiac disease is increasing, the country's preparedness towards the emerging epidemic of this disease is minimal. There are a number of issues, which requires urgent attention. Some of the key issues include increased awareness amongst health care professionals and the general public about the disease and its management, team-based management of patients with celiac disease, proper counseling and supervision of patients, training of dietitians in the management of patients with celiac disease, industrial production of reliable and affordable gluten-free food, and food labeling for gluten contents.

    Background Celiac disease is an autoimmune disease that affects approximately 1% of the US population. Disease is characterized by damage to the small intestinal lining and malabsorption of nutrients. Celiac disease is activated in genetically susceptible individuals by dietary exposure to gluten in wheat and gluten-like proteins in rye and barley. Symptoms are diverse and include gastrointestinal and extraintestinal manifestations. Treatment requires strict adherence to a gluten-free diet. The Internet is a major source of health information about celiac disease. Nonetheless, information about celiac disease that is available on various websites often is questioned by patients and other health care professionals regarding its reliability and content. Objectives To determine the accuracy, comprehensiveness, transparency, and readability of information on 100 of the most widely accessed websites that provide information on celiac disease. Methods Using the search term celiac disease, we analyzed 100 of the top English-language websites published by academic, commercial, nonprofit, and other professional (nonacademic) sources for accuracy, comprehensiveness, transparency, and reading grade level. Each site was assessed independently by 3 reviewers. Website accuracy and comprehensiveness were probed independently using a set of objective core information about celiac disease. We used 19 general criteria to assess website transparency. Website readability was determined by the Flesch-Kincaid reading grade level. Results for each parameter were analyzed independently. In addition, we weighted and combined parameters to generate an overall score, termed website quality. Results We included 98 websites in the final analysis. Of these, 47 (48%) provided specific information about celiac disease that was less than 95% accurate (ie, the predetermined cut-off considered a minimum acceptable level of accuracy).

    Background The prevalence of celiac disease and the use of medications that inhibit acid secretion have both increased in recent decades. Aims To explore the association between antisecretory medication exposure and subsequent development of celiac disease. Methods In this population-based case control study, we identified patients with celiac disease diagnosed at all pathology departments in Sweden from July 2005 through February 2008. Patients were matched by age and gender with up to 5 controls. We identified prior prescriptions for proton pump inhibitors and histamine-2 receptor antagonists in all subjects. We used conditional logistic regression to measure the association between these prescriptions and the subsequent diagnosis of celiac disease. Results Prior proton pump inhibitor prescription was strongly associated with celiac disease (OR 4.79; 95% CI 4.17-5.51). Patients prescribed both proton pump inhibitors and histamine-2 receptor antagonists had a higher risk of celiac disease (OR 5.96; 95% CI 3.58-9.91) than those prescribed proton pump inhibitors alone (OR 4.91; 95% CI 4.26-5.66) or histamine-2 receptor antagonists alone (OR 4.16; 95% CI 2.89-5.99). Conclusions Exposure to antisecretory medications is associated with a subsequent diagnosis of celiac disease. The persistence of this association after excluding prescriptions in the year preceding the celiac disease diagnosis suggests a causal relationship. PMID:24035759

    Celiac disease is an immune-mediated disease, triggered in genetically susceptible individuals by ingested gluten from wheat, rye, barley, and other closely related cereal grains. The only treatment for celiac disease is a strict gluten-free diet for life. This paper presents a systematic review of the scientific literature on the safety of pure oats for individuals with celiac disease, which historically has been subject to debate. Limitations identified within the scientific database include: limited data on long-term consumption, limited numbers of participants in challenge studies, and limited reporting about the reasons for withdrawals from study protocols. Furthermore, some evidence suggests that a small number of individuals with celiac disease may be intolerant to pure oats and some evidence from in vitro studies suggests that an immunological response to oat avenins can occur in the absence of clinical manifestations of celiac disease as well as suggesting that oat cultivars vary in toxicity. Based on the majority of the evidence provided in the scientific database, and despite the limitations, Health Canada and the Canadian Celiac Association (CCA) concluded that the majority of people with celiac disease can tolerate moderate amounts of pure oats. The incorporation of oats into a gluten-free diet provides high fiber and vitamin B content, increased palatability, and beneficial effects on cardiovascular health. However, it is recommended that individuals with celiac disease should have both initial and long-term assessments by a health professional when introducing pure oats into a gluten-free diet.

    As the increase in lifespan brings to light diseases that were previously not clinically detectable, osteoporosis has become an issue of worldwide significance. The disease is marked by a loss of bone mass; the bones become less dense, fragile and more prone to fracturing. Because it is regulated by endocrine and environmental factors, osteoporosis presents a multifactorial etiopathogenesis, with the genetic component accounting for 70% of an individual variation in bone mass density (BMD), the principal determinant, with age, of fracture risk. Pathological conditions such as celiac disease (CD) exacerbate the process of bone loss, so that the occurrence of osteoporosis in celiac subjects is of particular note: indeed, the screening of osteoporosis patients for this disease is advisable, since it may be the only sign of undiagnosed CD. An increase in interleukin IL-1β, of the IL-1 system, in the relatives of celiac patients confirms the genetic predisposition to osteoporosis and its presence is evidence of an association between the two conditions. The direct effect on the bones of CD is secondary to poor absorption of calcium and vitamin D. In women osteoporosis is indirectly associated with early menopause and amenorrhea, and it may follow prolonged breast-feeding and frequent pregnancies, while in men it is associated with hypogonadism and GH deficit. These endocrine and non-endocrine factors exert their effects on bones by modulating the RANK/RANK-L/OPG system. An appropriate lifestyle from adolescence onwards, together with early diagnosis of and treatment for CD and primary and secondary endocrine pathologies are important for the prevention of damage to the bones.

    This guideline presents recommendations for the diagnosis and management of patients with celiac disease. Celiac disease is an immune-based reaction to dietary gluten (storage protein for wheat, barley and rye) that primarily affects the small intestine in those with a genetic predisposition and resolves with exclusion of gluten from the diet. There has been a substantial increase in the prevalence of celiac disease over the last 50 years and an increase in the rate of diagnosis in the last 10 years. Celiac disease can present with many symptoms, including typical gastrointestinal symptoms (e.g. diarrhea, steatorrhea, weight loss, bloating, flatulence, abdominal pain) and also non-gastrointestinal abnormalities (e.g. abnormal liver function tests, iron deficiency anemia, bone disease, skin disorders, and many other protean manifestations). Indeed, many individuals with celiac disease may have no symptoms at all. Celiac disease is usually detected by serologic testing of celiac-specific antibodies. The diagnosis is confirmed by duodenal mucosal biopsies. Both serology and biopsy should be performed on a gluten-containing diet. The treatment for celiac disease is primarily a gluten-free diet (GFD), which requires significant patient education, motivation, and follow-up. Non-responsive celiac disease occurs frequently, particularly in those diagnosed in adulthood. Persistent or recurring symptoms should lead to a review of the patient’s original diagnosis to exclude alternative diagnoses, a review of the GFD to ensure there is no obvious gluten contamination, and serologic testing to confirm adherence with the GFD. In addition, evaluation for disorders associated with celiac disease that could cause persistent symptoms, such as microscopic colitis, pancreatic exocrine dysfunction, and complications of celiac disease, such as enteropathy-associated lymphoma or refractory celiac disease, should be entertained. Newer therapeutic modalities are being studied in clinical

    Celiac disease (CD), a malabsorption syndrome caused by hypersensitivity to gliadin fraction of gluten. CD can manifest with classic symptoms; however, significant myopathy and multiple fractures are rarely the predominant presentation of untreated celiac disease. Osteomalacia complicating celiac disease had become more and more rare. We describe here a case of osteomalacia secondary to a longstanding untreated celiac disease. This patient complained about progressive bone and muscular pain, weakness, fractures and skeletal deformities. Radiological and laboratory findings were all in favor of severe osteomalacia. Improvement of patient's weakness and laboratory abnormalities was obvious after treatment with gluten free diet, vitamin D, calcium and iron. This case affirms that chronic untreated celiac disease, can lead to an important bone loss and irreversible complications like skeletal deformities. PMID:25667705

    AIM: To identify the seroprevalence of celiac disease among healthy Saudi adolescents. METHODS: Between December 2007 and January 2008, healthy students from the 10th to 12th grades were randomly selected from three regions in Saudi Arabia. These regions included the following: (1) Aseer region, with a student population of 25512; (2) Madinah, with a student population of 23852; and (3) Al-Qaseem, with a student population of 16067. Demographic data were recorded, and a venous blood sample (5-10 mL) was taken from each student. The blood samples were tested for immunoglobulin A and immunoglobulin G endomysial antibodies (EMA) by indirect immunofluorescence. RESULTS: In total, 1167 students (614 males and 553 females) from these three regions were randomly selected. The majority of the study population was classified as lower middle class (82.7%). There were 26 (2.2%) students who had a positive anti-EMA test, including 17 females (3.1%) and 9 males (1.5%). Al-Qaseem region had the highest celiac disease prevalence among the three studied regions in Saudi Arabia (3.1%). The prevalence by region was as follows: Aseer 2.1% (10/479), Madinah 1.8% (8/436), and Al-Qaseem 3.2% (8/252). The prevalence in Madinah was significantly lower than the prevalence in Aseer and Al-Qaseem (P = 0.02). CONCLUSION: Our data suggest celiac disease prevalence might be one of the highest in the world. Further studies are needed to determine the real prevalence. PMID:23613632

    2011-01-01

    Executive Summary Objective The objective of this evidence-based analysis was to evaluate the clinical utility of serologic testing for celiac disease in asymptomatic individuals presenting with one of the non-gastrointestinal conditions evaluated in this report. The clinical utility was based on the effects of a gluten-free diet (GFD) on outcomes specific to each of these conditions. The prevalence of celiac disease in asymptomatic individuals and one of these non-gastrointestinal conditions was also evaluated. Clinical Need and Target Population Celiac Disease Celiac disease is an autoimmune disease characterized by a chronic inflammatory state of the proximal small bowel mucosa accompanied by structural and functional changes. Technology Under Evaluation Serologic Tests for Celiac Disease There are a number of serologic tests for celiac disease available. Serologic tests are automated with the exception of the anti-endomysial antibody test, which is more time-consuming and operator-dependent than the other tests. Research Questions What is the prevalence of asymptomatic celiac disease in patients presenting with one of the non-gastrointestinal conditions evaluated? What is the effect of the gluten-free diet on condition-specific outcomes in patients with asymptomatic celiac disease presenting with one of the non-gastrointestinal conditions evaluated? What is the clinical utility of serologic testing for celiac disease in asymptomatic patients presenting with one of the non-gastrointestinal conditions evaluated? The clinical utility was defined as the impact of the GFD on disease specific outcomes. What is the risk of all-cause mortality and lymphoma in individuals with asymptomatic celiac disease? What is the budget impact of serologic testing for celiac disease in asymptomatic subjects presenting with one of the non-gastrointestinal conditions evaluated?

    Celiac disease (CD) is common and occurs in both children and adults. A recent bibliometric study revealed that the journal with the most CD articles was the Journal of Pediatric Gastroenterology and Nutrition followed by the American Journal of Gastroenterology, a journal predominantly concerned with adult issues. To assess the quality and complexity of CD, research appearing in these journals used strict published criteria to assess the quality of the research in the 30 most recent research articles in each journal. The authors found that the research reported in these articles was of similar high quality and complexity. PMID:23838822

    This is a selective review of the literature concerning the methods of celiac disease treatment, which can be an alternative to a gluten-free diet. The most advanced studies are devoted to the larazotide acetate (AT-1001, human zonulin inhibitor) and prolyl-endopeptidases degrading toxic gluten peptides (ALV003, AN-PEP). It is estimated that they will be registered within a few years. They will not become an alternative to the gluten-free diet but rather a supplement to it, which will enable patients to ease the nutritional restrictions. PMID:25960809

    Decreased kidney function from kidney deposition of calcium oxalate has been previously described in inflammatory bowel disease as well as following jejuno-ileal and Roux-en-Y gastric bypass surgeries. Although celiac disease is the most prevalent bowel abnormality associated with intestinal malabsorption, its relationship to high kidney oxalate burden and decreased kidney function has not been established. We report a case of subclinical celiac disease and hyperoxaluria that presented with loss of kidney function as a result of high oxalate load in the absence of overt diarrhea, documented intestinal fat malabsorption, and nephrolithiasis. Subclinical celiac disease is commonly overlooked and hyperoxaluria is not usually investigated in kidney patients. We propose that this entity should be suspected in patients with chronic kidney disease in which the etiology of kidney damage has not been clearly established. PMID:22739230

    There are few reports in the literature where celiac disease presents with tongue manifestations, although atypical presentations of celiac disease are not uncommon. This case report highlights an atypical presentation of celiac disease in an elderly female. Our patient presented to clinic with complaints of a burning tongue for the past two years as well as occasional loose stools and fatigue. Work-up revealed iron deficiency anemia, zinc deficiency and an abnormal celiac panel. Complete symptom improvement was noted by 10 weeks into the initiation of a gluten free diet. Celiac disease can present at any age and should be considered as a differential in findings of malabsorption and gastrointestinal symptoms. PMID:27443108

    AIM: To estimate the burden of undiagnosed celiac disease (CD) in the Mediterranean area in terms of morbidity, mortality and health cost. METHODS: For statistics regarding the population of each country in the Mediterranean area, we accessed authoritative international sources (World Bank, World Health Organization and United Nations). The prevalence of CD was obtained for most countries from published reports. An overall prevalence rate of 1% cases/total population was finally estimated to represent the frequency of the disease in the area, since none of the available confidence intervals of the reported rates significantly excluded this rate. The distribution of symptoms and complications was obtained from reliable reports in the same cohort. A standardized mortality rate of 1.8 was obtained from recent reports. Crude health cost was estimated for the years between symptoms and diagnosis for adults and children, and was standardized for purchasing power parity to account for the different economic profiles amongst Mediterranean countries. RESULTS: In the next 10 years, the Mediterranean area will have about half a billion inhabitants, of which 120 million will be children. The projected number of CD diagnoses in 2020 is 5 million cases (1 million celiac children), with a relative increase of 11% compared to 2010. Based on the 2010 rate, there will be about 550 000 symptomatic adults and about 240 000 sick children: 85% of the symptomatic patients will suffer from gastrointestinal complaints, 40% are likely to have anemia, 30% will likely have osteopenia, 20% of children will have short stature, and 10% will have abnormal liver enzymes. The estimated standardized medical costs for symptomatic celiac patients during the delay between symptom onset and diagnosis (mean 6 years for adults, 2 years for children) will be about €4 billion (€387 million for children) over the next 10 years. A delay in diagnosis is expected to increase mortality: about 600 000

    Celiac disease is an autoimmune disorder which can present with a variety of non-gastrointestinal manifestations. In women, it may manifest with an assortment of gynecologic or obstetric disorders. Some reports have linked female infertility with undiagnosed celiac disease. Though there are a number of studies from Europe and the Middle East, only two prior American studies have examined the prevalence of “silent” celiac disease in a female infertility population. We prospectively performed serologic screening for celiac disease in 188 infertile women (ages 25–39). While we did not demonstrate an increased prevalence of celiac disease in our overall infertile female population, we were able to detect a significantly increased prevalence (5.9%) of undiagnosed celiac disease among women presenting with unexplained infertility (n=51). Our findings suggest the importance of screening infertile female patients, particularly those with unexplained infertility, for celiac disease. PMID:21682114

    Background The prevalence of diagnosed celiac disease is less than 1 in 2,000 in the United States, but screening studies undertaken in European and other populations have revealed a much higher prevalence. Objectives To determine the prevalence of celiac disease and the utility of screening in the general adult population of a geographically isolated area. Methods Serum tissue transglutaminase antibodies (tTG-IgA) were measured in volunteer health care participants aged 18 years and over at Annual Casper, Wyoming Blue Envelope Health Fair Blood Draw. Subjects with positive tTG-IgA tests had their endomysial IgA antibodies checked. Double positives were offered endoscopy with small bowel biopsy. All subjects completed a short GI symptom questionnaire. Results 3850 residents of the Natrona County had serologic evaluation for celiac disease, 34 of whom tested positive for both tTG and EMA IgA. Excluding three individuals with previous diagnosis of celiac disease, the overall prevalence of celiac serology positive in this community sample was 0.8%. All 31 subjects were offered a small bowel biopsy. Seventeen of the 18 biopsied subjects (94%) had at least partial villous atrophy. Symptoms that were reported by the fair attendees did not predict positivity. Conclusions Screening for celiac disease was widely accepted in this preventative healthcare setting. Undiagnosed celiac disease affects 1 in 126 individuals in this Wyoming community. Most were asymptomatic or had atypical presentations. Serologic testing can readily detect this disease in a general population. PMID:21364545

    AIM: To determine the prevalence of celiac disease in a randomly selected population sample. METHODS: A total of 2157 subjects (1036 males; 1121 females) participating in a population-based cross-sectional study underwent laboratory testing for tissue transglutaminase and antibodies to immunoglobulin A, endomysium and antigliadin. In a second step, all subjects who had been examined serologically were surveyed using a questionnaire that included questions specific to celiac disease. Subjects with positive antibody titers and those with histories positive for celiac disease then underwent biopsy. At the first follow up, antibody titers were again determined in these subjects and subjects were questioned regarding symptoms specific for celiac disease and disorders associated with celiac disease. The second follow up consisted of a telephone interview with subjects positive for celiac disease. RESULTS: Antibody tests consistent with celiac disease were reported in eight subjects, corresponding to an overall prevalence of 1:270 (8/2157). The prevalence among women was 1:224 and 1:518 in men. Classical symptoms were observed in 62.5% of subjects. Atypical celiac disease was present in 25.0%, and transient celiac disease in 12.5%. False-negative test results were returned in three subjects. This yields a sensitivity and specificity of 62.5% and 50.0%, respectively, for tissue transglutaminase immunoglobulin-A antibody; of 62.5% and 71.4% respectively, for endomysium antibody; and of 62.5% and 71.4%, respectively, for antigliadin antibody. CONCLUSION: The prevalence rate in our collective lies within the middle tertile of comparable studies in Europe. The use of a single antibody test for screening purposes must be called into question. PMID:23674868

    Aim: The present study aimed to study the immunological changes seen in the intestinal epithelium of the celiac patients could also be detected in the peripheral blood lymphocyte populations. Background: Celiac disease (CD) is a small bowel enteropathy caused by permanent wheat gluten intolerance. One of the earliest signs of CD is an increase in the numbers of the intestinal intraepithelial lymphocytes (iIEL). Patients and methods: In this case-control study, totally 13 untreated subjects with acceptable criteria for CD without any complication and 16 healthy subjects without any positive criteria for CD were selected. Peripheral blood T cells were analyzed by two-color flow cytometry in both groups. Results: The mean age of patients was 33.6 ± 3.4 years and two patients had Marsh IIIB, five patients had Marsh IIIA and six patients had Marsh II histology class. The mean percentages of the TCR+ T cells in the patients were significantly higher than the controls (p=0.015). However, the mean percentages of the αβTCR+ T cells were significantly lower in the untreated patients than the controls (p=0.025). There were no significant difference between the mean percentages of lymphocytes expressing the CD3, CD4 and CD8 molecules in the patients and the controls. Conclusion: The change in the percentages of the peripheral blood T cells expressing the γδTCR and αβTCR in the celiac patients could be used in conjunction with the other serological markers to identify new CD cases.

    Celiac disease is a permanent intolerance to the gliadin fraction of wheat gluten and to similar barley and rye proteins that occurs in genetically susceptible subjects. After ingestion, degraded gluten proteins reach the small intestine and trigger an inappropriate T cell-mediated immune response, which can result in intestinal mucosal inflammation and extraintestinal manifestations. To date, no pharmacological treatment is available to gluten-intolerant patients, and a strict, life-long gluten-free diet is the only safe and efficient treatment available. Inevitably, this may produce considerable psychological, emotional, and economic stress. Therefore, the scientific community is very interested in establishing alternative or adjunctive treatments. Attractive and novel forms of therapy include strategies to eliminate detrimental gluten peptides from the celiac diet so that the immunogenic effect of the gluten epitopes can be neutralized, as well as strategies to block the gluten-induced inflammatory response. In the present paper, we review recent developments in the use of enzymes as additives or as processing aids in the food biotechnology industry to detoxify gluten. PMID:21048862

    From the time of Gee’s landmark writings, the recent history of celiac disease (CD) can be divided into many ages, each driven by a diagnostic advance and a deeper knowledge of disease pathogenesis. At the same time, these advances were paralleled by the identification of new clinical patterns associated with CD and by a continuous redefinition of the prevalence of the disease in population. In the beginning, CD was considered a chronic indigestion, even if the causative food was not known; later, the disease was proven to depend on an intolerance to wheat gliadin, leading to typical mucosal changes in the gut and to a malabsorption syndrome. This knowledge led to curing the disease with a gluten-free diet. After the identification of antibodies to gluten (AGA) in the serum of patients and the identification of gluten-specific lymphocytes in the mucosa, CD was described as an immune disorder, resembling a chronic “gluten infection”. The use of serological testing for AGA allowed identification of the higher prevalence of this disorder, revealing atypical patterns of presentation. More recently, the characterization of autoantibodies to endomysium and to transglutaminase shifted the attention to a complex autoimmune pathogenesis and to the increased risk of developing autoimmune disorders in untreated CD. New diagnostic assays, based on molecular technologies, will introduce new changes, with the promise of better defining the spectrum of gluten reactivity and the real burden of gluten related-disorders in the population. Herein, we describe the different periods of CD experience, and further developments for the next celiac age will be proposed. PMID:21990947

    This work presents the development and test of an anti-gliadin antibodies biosensor based on lossy mode resonances (LMRs) to detect celiac disease. Several polyelectrolites were used to perform layer-by-layer assembly processes in order to generate the LMR and to fabricate a gliadin-embedded thin-film. The LMR shifted 20 nm when immersed in a 5 ppm anti-gliadin antibodies-PBS solution, what makes this bioprobe suitable for detecting celiac disease. This is the first time, to our knowledge, that LMRs are used to detect celiac disease and these results suppose promising prospects on the use of such phenomena as biological detectors.

    2010-09-01

    Celiac disease (CD) is an immune-mediated enteropathy that is secondary to gluten ingestion and classically associated with gastrointestinal symptoms. Diagnosis is based on serology and confirmatory duodenal biopsy, and the only treatment is lifelong avoidance of gluten. CD has been increasingly recognized to encompass a wide variety of manifestations that are relevant to women’s health, including infertility, adverse pregnancy outcomes and reduced BMD. Currently, CD is underdiagnosed, largely owing to lack of recognition of the diverse manifestations by general practitioners. Increased awareness of the clinical spectrum of this disease, as well as targeted testing in at-risk individuals (including women with unexplained infertility and previous adverse pregnancy outcomes, and in specific populations with reduced BMD) is greatly needed in order to improve rates of diagnosis.

    Aim: The aim of this study was to evaluate clinical and laboratory findings and determine the prevalence of celiac disease (CD) in children with Hashimoto thyroiditis (HT). Material and Methods: The data of a total of 80 patients with positive anti-thyroid antibodies who were aged between 6 and 17.9 years were retrospectively studied. Age, gender, complaints at the time of presentation, family history of thyroid disorders, clinical and laboratory findings were recorded. The levels of thyrotropin, free thyroxin, thyroid autoantibodies (thyroid peroxidase and thyroglobulin antibodies), immunoglobulin A (IgA), anti-tissue transglutaminase antibodies (IgA-tTG), and thyroid ultrasonography findings were enrolled. Results: Eighty patients (65 females (81.2%) and 15 males (18,8%)) were included in the study. Family history of thyroid disease was present in 38 (47.5%) patients. The most common complaints at the time of presentation were goiter (%30) and weight gain (%25). Forty three (53.8%), 23 (28.7%), and 14 (17.5%) patients presented with euthyroidism, subclinical hypothyroidism and obvious hypothyroidism. Thirty seven (46.2%) patients had goiter. IgA-tTG was found to be positive after a diagnosis of HT was made in only one patient (1.25%) and the diagnosis of CD was confirmed when intestinal biopsy of this patient revealed villus atrophy, crypt hyperplasia and increase in the intraepithelial lymphocyte count. Conclusions: In our study, it was found that the most common complaints at presentation in patients with a diagnosis of hashimoto thyroiditis included goiter, weakness and weight gain and the prevalence of celiac diseases was found to be 1.25% (1/80). This study shows that the prevalence of CD in patients with a diagnosis of HT is higher compared to the prevalence in the healthy pediatric population. PMID:27489467

    Celiac disease (CD) is a common autoimmune condition. Previously it was considered to be a rare childhood disorder, but is actually considered a relatively common condition, present at any age, which may have multiple complications and manifestations. Hematological disorders of the disease are not uncommon. Among these disorders, the most frequently reported are anemias as a result of iron deficiency, often associated with folate and/or B12 deficiency. Anemias caused by hemolysis are very rarely reported in celiac patients. An 11-year-old girl with a previous uneventful medical history presented with severe hemolytic anemia. Hemolysis was Coombs negative, accompanied by inappropriate low reticulocyte count, despite exaggerated bone marrow hyperplasia of the erythroid precursors which showed normal maturation. Serology for recent infections, including Epstein-Barr virus, parvovirus B19, cytomegalovirus and mycoplasma, were all negative. Levels of serum IgA, IgG and IgM, were all within normal ranges for age. Screening for anti-DNA, antinuclear, antineutrophil cytoplasmic, antimicrosomal, antithyroglobulin, and antimitochondrial antibodies and lupus anticoagulants, was negative. She was also negative for human immunodeficiency virus. Conventional therapy with corticosteroids and intravenous immunoglobulin failed. CD was serendipitously discovered upon screening for anti-tissue transglutaminase autoantibodies. The disease was confirmed by biopsy of the small intestine mucosa. The patient recovered with gluten-free diet. A unique case of CD is presented. CD should be serologically screened in each patient with Coombs negative “immune” hemolytic anemia, particularly if accompanied by “reticulocytopenia”. A new hemolytic mechanism and very speculative explanation for “reticulocytopenia” are discussed. PMID:21105201

    Celiac disease (CD) is a chronic immune-mediated gluten dependent enteropathy induced by ingestion of gluten, characterized by intestinal malabsorption and subtotals or total atrophy of intestinal villi. The predominant consequence of CD in untreated patients, is malnutrition as a result of malabsorption. Moreover, several and increasing extra-intestinal clinical manifestations have been described in the CD patients. Strict adherence to a gluten-free diet (GFD) improves nutritional status, inducing an increase in fat and bone compartments, but does not completely normalize body composition and nutritional deficiencies. An early and accurate evaluation of nutritional status can be of the pivotal step in the clinical management of the adult CD patients. The aim of this review is to present the most important and recent data on nutritional and metabolic features in the CD adult patients, the related implications and the effects of the GFD on these conditions.

    Low bone mineral density (BMD), osteopenia, and osteoporosis are frequent complications of celiac disease (CD). The etiology of pathologic bone alterations in CD is multifactorial; however, two main mechanisms are involved: intestinal malabsorption and chronic inflammation. A strict gluten-free diet (GFD) is thought to be the only effective treatment for CD; but treating bone complications related to CD remains complex. The objective of this review is to elucidate the bones problems related to CD and to increase awareness of osteoporosis development, considered as a sign of atypical CD presentation. Currently, a question of whether GFD alone is an effective treatment to correct the bone alterations in patients with CD is under debate. This review presents factors contributing to pathologic bone derangement, recent research on the epidemiology of low BMD, osteoporosis, and fractures, and the treatment of bone problems in patients with CD. The roles of calcium and transport mechanisms are additionally presented. PMID:24290593

    The basis for celiac disease (CD) treatment is a strict lifelong gluten-free diet. On the diet, the small intestinal mucosal injury heals and gluten-induced symptoms and signs disappear. The mucosal healing is a prerequisite for sustaining health and is also obtained with a diet containing oats and trace amounts of gluten, industrially purified wheat starch-based gluten-free products. The small intestinal mucosa does not heal in noncompliant people, nor when a patient is inadvertently ingesting gluten. Development of adjunctive or alternative therapies is on its way. There are several novel treatment pipelines within academy and industry. Examples are the ideas of using glutenases as a drug to degrade the ingested gluten, polymers to bind and sequester the gluten to the feces, and also vaccine development for an immunotherapy to induce tolerance towards gluten. Clinical drug trials are to be foreseen in CD, soon also in children. PMID:24979194

    This study aimed to investigate the salivary microbiota and metabolome of 13 children with celiac disease (CD) under a gluten-free diet (treated celiac disease [T-CD]). The same number of healthy children (HC) was used as controls. The salivary microbiota was analyzed by an integrated approach using culture-dependent and -independent methods. Metabolome analysis was carried out by gas chromatography-mass spectrometry–solid-phase microextraction. Compared to HC, the number of some cultivable bacterial groups (e.g., total anaerobes) significantly (P < 0.05) differed in the saliva samples of the T-CD children. As shown by community-level catabolic profiles, the highest Shannon's diversity and substrate richness were found in HC. Pyrosequencing data showed the highest richness estimator and diversity index values for HC. Levels of Lachnospiraceae, Gemellaceae, and Streptococcus sanguinis were highest for the T-CD children. Streptococcus thermophilus levels were markedly decreased in T-CD children. The saliva of T-CD children showed the largest amount of Bacteroidetes (e.g., Porphyromonas sp., Porphyromonas endodontalis, and Prevotella nanceiensis), together with the smallest amount of Actinobacteria. T-CD children were also characterized by decreased levels of some Actinomyces species, Atopobium species, and Corynebacterium durum. Rothia mucilaginosa was the only Actinobacteria species found at the highest level in T-CD children. As shown by multivariate statistical analyses, the levels of organic volatile compounds markedly differentiated T-CD children. Some compounds (e.g., ethyl-acetate, nonanal, and 2-hexanone) were found to be associated with T-CD children. Correlations (false discovery rate [FDR], <0.05) were found between the relative abundances of bacteria and some volatile organic compounds (VOCs). The findings of this study indicated that CD is associated with oral dysbiosis that could affect the oral metabolome. PMID:24657864

    Objectives: Celiac disease, an autoimmune disease, is related to immune mediated intolerance to gluten. Some studies suggest that Celiac Disease was 20 times more frequent in type 1 patients with diabetes. The objective of our study was to evaluate the prevalence of celiac disease in hospital based type 1 diabetic adults. Methods: Our study was carried out retrospectively in Medeniyet University Goztepe Training and Educational Hospital in Istanbul between 2012–2013. The cohort comprised 482 type 1 patients with diabetes attending the diabetes outpatient clinic. The data were analyzed by SPSS 10.5 package program. Student’s t tests is used for comparative analyses. A p-value less than 0.05 was considered statistically significant. Results: The cohort included 482 type 1 patients with diabetes. Fifty seven of them were not evaluated for Endomysium antibody positivity. Fifteen of the remaining 425 patients were positive for anti endomysial antibody (3.5%). The prevalence of biopsy proven celiac disease was 2.3% (10/425). There was no significant difference between Endomysial antibody positive and negative groups in regard of age, sex, or duration of the disease. Conclusion: This study confirms that the celiac disease is common in type 1 diabetic patients. Since a small proportion of celiac patients are symptomatic this disorder should be screened in all adult type 1 patients with diabetes by antiendomysium antibody. PMID:26430419

  2. Hemoptysis in patients of celiac disease with disproportionately severe anemia: tip of the iceberg?

    PubMed Central

    2013-01-01

    Idiopathic Pulmonary Hemosiderosis (IPH) is characterized by the triad of iron deficiency anemia, pulmonary infiltrates and haemoptysis with no recognizable cause. Since the first description of its association with Celiac Disease (CD) by Lane and Hamilton in 1971, only a few isolated cases have been reported in literature. Although it has been considered an uncommon association of two disease entities, recent reports indicate that prevalence of celiac disease is as high as one percent. Further, individually both celiac disease and IPH are known to present as refractory anemia only. We are reporting a young adult with Lane Hamilton Syndrome, who realized that he was having significant gastrointestinal complaints only when they disappeared on gluten free diet (GFD). This case report reiterates the fact that celiac disease should be considered in all patients of IPH because of the therapeutic implications. Further on review of literature, we believe that covert hemoptysis may be responsible for disproportionately severe anemia in patients of celiac disease. Thus, prevalence of this association may be more than currently believed. Further research in this regard may improve our understanding of pathogenesis of celiac disease. PMID:23514358

    Although dietary gluten is the trigger, celiac disease risk is strongly influenced by genetic variation in the major histocompatibility complex (MHC) region. We fine-mapped the MHC association signal to identify additional risk factors independent of the HLA-DQ alleles and observed five novel associations that account for 18% of the genetic risk. Together with the 57 known non-MHC loci, genetic variation can now explain up to 48% of celiac disease heritability. PMID:25894500

    BACKGROUND The inflammatory disorders type 1 diabetes (T1D) and celiac disease co-segregate in populations, suggesting a common genetic origin. Both are associated with the HLA class II genes on chromosome 6p21, and the present paper tested whether non-HLA loci are shared. METHODS We evaluated eight celiac disease risk loci in T1D by genotyping and statistical analyses of 8,064 T1D cases, 9,339 controls and 2,519 families. We also investigated 18 T1D loci in 2,560 celiac disease cases and 9,339 controls. RESULTS Three celiac disease loci, listed as chromosome/candidate gene: 1q31/RGS1, 2q12/IL18RAP and 6q25/TAGAP, were associated with T1D (P < 10−4). The 3p21/CCR5 32 base pair insertion/deletion variant was newly identified as a T1D locus (P = 1.81 × 10−8), and was also associated with celiac disease, as were 18p11/PTPN2 and 2q33/CTLA4, bringing the total loci shared to seven, including 12q24/SH2B3. The 2q12/IL18RAP and 6q25/TAGAP allele associations were in the opposite direction in T1D as compared to celiac disease. Distinct effects included 11p15/INS, 10p15/IL2RA and 1q13/PTPN22 in T1D and 3q25/IL12A and 3q28/LPP in celiac disease. CONCLUSIONS Genetic susceptibility to T1D and celiac disease shares common alleles. These data suggest that common biological mechanisms, such as autoimmunity related tissue damage and intolerance to dietary antigens may be a feature of T1D. PMID:19073967

    BACKGROUND: Celiac disease (CD) is mostly recognized among subjects with a Caucasian ethnic ancestry. No studies have explored conditions predisposing Amerindians to CD. OBJECTIVE: To prospectively assess environmental, genetic and serological conditions associated with CD among members of the Toba native population attending a multidisciplinary sanitary mission. METHODS: An expert nutritionist determined daily gluten intake using an established questionnaire. Gene typing for the human leukocyte antigen (HLA) class II alleles was performed on DNA extracted from peripheral blood (HLA DQ2/DQ8 haplotype). Serum antibodies were immunoglobulin (Ig) A tissue transglutaminase (tTG) and the composite deamidated gliadin peptides/tTG Screen test. Positive cases were tested for IgA endomysial antibodies. RESULTS: A total of 144 subjects (55% female) were screened. The estimated mean gluten consumption was 43 g/day (range 3 g/day to 185 g/day). Genetic typing showed that 73 of 144 (50.7%) subjects had alleles associated with CD; 69 (94.5%) of these subjects had alleles for HLA DQ8 and four had DQ2 (5.5%). Four and six subjects had antibody concentrations above the cut-off established by the authors’ laboratory (>3 times the upper limit of normal) for IgA tTG and deamidated gliadin peptides/tTG screen, respectively. Four of these had concomitant positivity for both assays and endomysial antibodies were positive in three subjects who also presented a predisposing haplotype. CONCLUSION: The present study was the first to detect CD in Amerindians. The native Toba ethnic population has very high daily gluten consumption and a predisposing genetic background. We detected subjects with persistent CD autoimmunity and, at least, three of them fulfilled serological criteria for CD diagnosis. PMID:26207618

  7. Igs as Substrates for Transglutaminase 2: Implications for Autoantibody Production in Celiac Disease

    2015-01-01

    Autoantibodies specific for the enzyme transglutaminase 2 (TG2) are a hallmark of the gluten-sensitive enteropathy celiac disease. Production of the Abs is strictly dependent on exposure to dietary gluten proteins, thus raising the question how a foreign Ag (gluten) can induce an autoimmune response. It has been suggested that TG2-reactive B cells are activated by gluten-reactive T cells following receptor-mediated uptake of TG2–gluten complexes. In this study, we propose a revised model that is based on the ability of the BCR to serve as a substrate to TG2 and become cross-linked to gluten-derived peptides. We show that TG2-specific IgD molecules are preferred in the reaction and that binding of TG2 via a common epitope targeted by cells using the IgH variable gene segment (IGHV)5–51 results in more efficient cross-linking. Based on these findings we hypothesize that IgD-expressing B cells using IGHV5–51 are preferentially activated, and we suggest that this property can explain the previously reported low number of somatic mutations as well as the overrepresentation of IGHV5–51 among TG2-specific plasma cells in the celiac lesion. The model also couples gluten peptide uptake by TG2-reactive B cells directly to peptide deamidation, which is necessary for the activation of gluten-reactive T cells. It thereby provides a link between gluten deamidation, T cell activation, and the production of TG2-specific Abs. These are all key events in the development of celiac disease, and by connecting them the model may explain why the same enzyme that catalyzes gluten deamidation is also an autoantigen, something that is hardly coincidental.

    Background In earlier studies based on selected populations, the relative risk for thyroid cancer in celiac disease has varied between 0.6 and 22.5. We aimed to test this relationship in a population-based setting. Methods We collected small intestinal biopsy report data performed in 1969–2008 from all 28 Swedish pathology departments. 29,074 individuals with celiac disease (villous atrophy; Marsh histopathology stage III) were matched for sex, age, calendar year, and county to 144,440 reference individuals from the Swedish general population. Through Cox regression, we then estimated hazard ratios (HRs) and confidence intervals (CIs) for any thyroid cancer and papillary thyroid cancer (defined according to relevant pathology codes in the Swedish Cancer Register) in patients with celiac disease. Results During follow-up, any thyroid cancer developed in seven patients with celiac disease (expected=12) and papillary thyroid cancer developed in five patients (expected=7). Celiac disease was not associated with an increased risk of any thyroid cancer (HR 0.6 [CI 0.3–1.3]) or of papillary thyroid cancer (HR 0.7 [CI 0.3–1.8]). All cases of thyroid cancer in celiac disease occurred in female patients. Risk estimates were similar before and after the year 2000 and independent of age at celiac diagnosis (≤24 years vs. ≥25 years). Conclusions We conclude that, in the Swedish population, there is no increased risk of thyroid cancer in patients with celiac disease. This differs from what has been reported in smaller studies in Italy and the United States. PMID:23281890

    This commentary by the leadership of the North American Society for the Study of Celiac Disease (NASSCD) concerns recent research findings regarding infant feeding practices. Celiac disease has increased markedly in recent decades, and seroprevalence studies indicate that this is a true rise, rather than one due to increased awareness and testing. Prior studies have suggested that infant feeding practices and timing of initial gluten exposure are central to the development of celiac disease. Two recent multicenter randomized trials tested strategies of early or delayed gluten introduction in infants, and neither strategy appeared to influence celiac disease risk. These studies also found that breastfeeding did not protect against the development of celiac disease. While disappointing, these results should spur the study of wider environmental risk factors beyond infant feeding, such as intrauterine and perinatal exposures as well as environmental influences later in life, including drug exposure, microbial infections, and the microbiome. Given that celiac disease can develop at any age, it is imperative to study these proposed triggers so as to elucidate the loss of tolerance to gluten and to develop future intervention strategies.

    Introduction Small bowel adenocarcinoma is a rare entity most frequently observed with celiac disease. This is the first case report on the association of celiac disease, small bowel adenocarcinoma and intestinal malrotation. Case report A 40 year-old male patient diagnosed with celiac disease since the age of 5 years complained of epigastric pain and vomiting for three days. Computed tomography (CT) showed a significant gastroduodenal dilatation with thickened intestinal wall proximal to the duodenojejunal flexure. The lumen contained a food bezoar in the center. The duodenojejunal angle was abnormally on the right side of the abdomen and the superior mesenteric vein was anterior to the superior mesenteric artery. Endoscopy after aspiration found a hemi-circumferential and irregular mass which bled at the contact of fibroscope. Biopsies showed an adenocarcinoma and small bowel resection was performed. Discussion Celiac disease is associated with a high risk of small bowel cancer. The association of incomplete intestinal malrotation, duodenojejunal flexure tumor and celiac disease made the surgery challenging. Conclusion Patients with celiac disease should be carefully monitored and endoscopic or radiologic investigations should be carried out in patients with any doubtful symptoms. PMID:26670410

  11. Possible association between celiac disease and bacterial transglutaminase in food processing: a hypothesis.

    PubMed

    Lerner, Aaron; Matthias, Torsten

    2015-08-01

    The incidence of celiac disease is increasing worldwide, and human tissue transglutaminase has long been considered the autoantigen of celiac disease. Concomitantly, the food industry has introduced ingredients such as microbial transglutaminase, which acts as a food glue, thereby revolutionizing food qualities. Several observations have led to the hypothesis that microbial transglutaminase is a new environmental enhancer of celiac disease. First, microbial transglutaminase deamidates/transamidates glutens such as the endogenous human tissue transglutaminase. It is capable of crosslinking proteins and other macromolecules, thereby changing their antigenicity and resulting in an increased antigenic load presented to the immune system. Second, it increases the stability of protein against proteinases, thus diminishing foreign protein elimination. Infections and the crosslinked nutritional constituent gluten and microbial transglutaminase increase the permeability of the intestine, where microbial transglutaminases are necessary for bacterial survival. The resulting intestinal leakage allows more immunogenic foreign molecules to induce celiac disease. The increased use of microbial transglutaminase in food processing may promote celiac pathogenesis ex vivo, where deamidation/transamidation starts, possibly explaining the surge in incidence of celiac disease. If future research substantiates this hypothesis, the findings will affect food product labeling, food additive policies of the food industry, and consumer health education. PMID:26084478

    This paper provides an overview of the latest scientific data related to the safety of uncontaminated oats (<20 ppm of gluten) in the diet of individuals with celiac disease (CD). It updates the previous Health Canada position posted on the Health Canada website in 2007 and a related paper published in 2009. It considers a number of recent studies published between January 2008 and January 2015. While recognizing that a few people with celiac disease seem to be clinically intolerant to oats, this review concludes that oats uncontaminated by gluten-containing cereals (wheat, rye, and barley) can be safely ingested by most patients with celiac disease and that there is no conclusive evidence that the consumption of uncontaminated or specially produced oats containing no greater than 20 ppm gluten by patients with celiac disease should be limited to a specific daily amount. However, individuals with CD should observe a stabilization phase before introducing uncontaminated oats to the gluten-free diet (GFD). Oats uncontaminated with gluten should only be introduced after all symptoms of celiac disease have resolved and the individual has been on a GFD for a minimum of 6 months. Long-term regular medical follow-up of these patients is recommended but this is no different recommendation to celiac individuals on a GFD without oats. PMID:27446825

    AIM: To compare anxiety and depression levels in adult patients with celiac disease (CD) on a gluten-free diet (GFD) with controls. METHODS: The levels of anxiety, depression and of a probable anxiety or depressive disorder were assessed by the Hospital Anxiety and Depression Scale in 441 adult patients with CD recruited by the German Celiac Society, in 235 age- and sex-matched patients with inflammatory bowel disease (IBD) in remission or with slight disease activity, and in 441 adult persons of a representative German general population sample (GP). Potential demographic (age, sex, social class, family status) and disease-related (latency to diagnosis, duration of GFD, compliance with GFD, thyroid disease) predictors of anxiety and depression in CD were tested for by regression analyses. RESULTS: The level of anxiety in CD patients was predicted (R2 = 0.07) by female gender (P = 0.01). Female sex (OR = 3.6, 95% CI: 1.3-9.4, P = 0.01) was associated with a probable anxiety disorder. Living alone (OR = 0.5, 95% CI: 0.2-0.9, P = 0.05) was associated with a reduced risk of an anxiety disorder. The level of depression and a probable depressive disorder were not predicted by any of the demographic and medical variables tested for. The levels of anxiety in patients with CD (6.6 ± 3.4) and with IBD (6.9 ± 3.7) were higher than those of persons in the GP (4.6 ± 3.3) (both P < 0.001). The levels of depression in persons with CD (4.2 ± 3.4), IBD (4.6 ± 3.4) and of the GP (4.2 ± 3.8) did not differ (P = 0.3). The prevalence of a probable anxiety disorder in persons with CD (16.8%) and IBD (14.0%) was higher than that of the GP (5.7%) (P < 0.001). The prevalence of a probable depressive disorder did not differ significantly between the three groups (P = 0.1). CONCLUSION: Anxiety in adult German female celiacs on a GFD is higher than in persons of the GP. Female celiacs on a GFD should be screened for anxiety. PMID:20533598

    Background Celiac disease is defined as a ‘chronic small intestinal immune-mediated enteropathy precipitated by exposure to dietary gluten in genetically predisposed individuals’. Sweden has experienced an “epidemic” of celiac disease in children below two years of age. Celiac disease etiology is considered multifactorial; however, little is known regarding potential risk- or protecting factors. We present data on the possible association between early infectious episodes and celiac disease, including their possible contribution to the Swedish celiac disease epidemic. Methods A population-based incident case-referent study (475 cases, 950 referents) with exposure information obtained via a questionnaire (including family characteristics, infant feeding, and the child’s general health) was performed. Celiac disease cases were diagnosed before two years of age, fulfilling the diagnostic criteria of the European Society for Pediatric Gastroenterology, Hepatology and Nutrition. Referents were randomly selected from the national population register after fulfilling matching criteria. The final analyses included 954 children, 373 (79%) cases and 581 (61%) referents, with complete information on main variables of interest in a matched set of one case with one or two referents. Results Having three or more parental-reported infectious episodes, regardless of type of infection, during the first six months of life was associated with a significantly increased risk for later celiac disease, and this remained after adjusting for infant feeding and socioeconomic status (odds ratio [OR] 1.5; 95% confidence interval [CI], 1.1-2.0; P=0.014). The celiac disease risk increased synergistically if, in addition to having several infectious episodes, infants were introduced to dietary gluten in large amounts, compared to small or medium amounts, after breastfeeding was discontinued (OR 5.6; 95% CI, 3.1-10; P<0.001). Conclusion This study suggests that having repeated

    Objective: This study aimed to evaluate the prevalence of celiac disease (CD) in the patients with dilated cardiomyopathy (DCM). Simultaneous presentation of these two diseases has been recently reported in some studies; however, few researches have been done on children. The sooner CD is diagnosed, the better the prognosis will be, especially in the patients with a chronic disease like DCM. Methods: In this study, 82 cases were screened for CD by measuring the level of anti-body against transglutaminase (anti tTG). These cases included 41 patients with DCM labeled according to clinical evaluation and echocardiography and 41 healthy children who had been referred for routine checkup. All the patients were between 1 and 18 years old. The expired patients and those with previous diagnosis of CD were excluded from the study. Besides, the patients with positive antibody results underwent intestinal biopsy to match the serology findings with histopathology of CD in the intestine. Finally, the data were analyzed by the SPSS statistical software (v. 16) and through t-test and Pearson correlation coefficient. Findings: According to the findings, 1/41 (2.5%) DCM cases had positive tTG antibody level and negative intestinal biopsy which is classified as potential CD in the children with DCM. In addition, 7/41 (17%) patients had borderline anti body level. A direct correlation was observed between age and anti tTG level. Conclusion: It is beneficial to assess CD in DCM children with unknown cause. PMID:25793066

    Introduction Celiac disease (CD) is caused due to intake of gluten, a protein component in wheat, barley, and rye. The only treatment currently available for CD is strict lifetime adherence to a gluten-free diet (GFD) which is a diet that excludes wheat, barley, and rye. There is limited information on barriers to following a GFD. The present study aimed to investigate the compliance with a GFD, barriers to compliance, and the impact of compliance on the quality of life (QOL) in Iranian children and adolescents suffering from CD. Methods In this cross-sectional study, a total of 65 known cases of CD (both males and females), diagnosed in Namazi Hospital, a large referral center in south of Iran, selected by census were studied in 2014. Dietary compliance was assessed using a questionnaire. A disease-specific QOL questionnaire for children with CD (the celiac disease DUX [CDDUX]) was used. Comparisons between categorical variables were performed using chi-square test. Results Sixty-five patients, 38 females (58.5%) and 27 (41.5%) males, were surveyed. Mean (± standard deviation [SD]) age of the respondents was 11.3 (±3.8) years. Dietary compliance was reported by 35 (53.8%) patients. The mean (± SD) CDDUX score was higher in dietary-compliant patients (33.5 [±19.4] vs 26.7 [±13.6], respectively, P=0.23). The score of CDDUX in parents of patients in dietary-compliant group was more than the noncompliant patients (28.1 [±13.5] vs 22.1 [±14], respectively, P=0.1). Barriers to noncompliance were poor or unavailability (100%), high cost (96.9%), insufficient labeling (84.6%), poor palatability (76.9%), and no information (69.23%). Conclusion Approximately half of the patients with CD reported dietary compliance. Poor or unavailability was found to be the most important barrier contributing to noncompliance. The QOL was better in compliant patients. Proposed strategies to improve compliance are greater availability of gluten-free products, better food labeling, and

    Rationale: In the setting of open access endoscopy, the recognition of suggestive endoscopic features in the duodenum can select patients with probability of celiac disease (CD). This could add to the current efforts to increase the diagnostic rate of this disease. Aim: The aim of this study was to evaluate the diagnostic accuracy of these markers for CD in an adult population undergoing endoscopy, without a prior serological testing. Methods and Results: Over a period of 3 years, between June 2012 and 2015, all the patients who underwent upper gastrointestinal endoscopy and presented one or more of the endoscopic markers consistent with CD, or those suspected for CD, irrespective of the presence of these markers, were included. Sensitivity, specificity, positive and negative predictive values were calculated for these markers in CD diagnosis. Among the 182 patients, 56.04% were females, with a mean age of 47.6 ± 13.9 years. 20/182 (10.99%) had a final diagnosis of CD. The presence of any endoscopic marker had a high sensitivity (95%) and a negative predictive value (98.41%). Bulb atrophy and reduced folds in the descending duodenum had a low diagnostic accuracy, while scalloping, mosaic pattern and fissures were highly specific for CD (98.77%, 99.38% and 98.77%) and their presence greatly increased the probability of CD, with a positive likelihood ratio of 24.3, 24.3 and 12.15, respectively. Discussions: A wide set of endoscopic markers, including the duodenal bulb, were evaluated in this study. Our results showed that the endoscopy with a careful examination of the duodenum is a sensitive indicator for CD.

    Celiac disease (CD) is an autoimmune enteropathy, characterized by an inappropriate T-cell-mediated immune response to the ingestion of certain dietary cereal proteins in genetically susceptible individuals. This disorder presents environmental, genetic, and immunological components. CD presents a prevalence of up to 1% in populations of European ancestry, yet a high percentage of cases remain underdiagnosed. The diagnosis and treatment should be made early since untreated disease causes growth retardation and atypical symptoms, like infertility or neurological disorders. The diagnostic criteria for CD, which requires endoscopy with small bowel biopsy, have been changing over the last few decades, especially due to the advent of serological tests with higher sensitivity and specificity. The use of serological markers can be very useful to rule out clinical suspicious cases and also to help monitor the patients, after adherence to a gluten-free diet. Since the current treatment consists of a life-long gluten-free diet, which leads to significant clinical and histological improvement, the standardization of an assay to assess in an unequivocal way gluten in gluten-free foodstuff is of major importance.

    Celiac disease (CD) is an immune-mediated systemic disorder elicited by gluten and related prolamines in genetically susceptible individuals and is characterized by the presence of a variable combination of gluten-dependent clinical manifestations, CD-specific antibodies, HLA-DQ2 or HLA-DQ8 haplotypes and enteropathy. CD is triggered by wheat gluten and related prolamines in barley and rye. Worldwide, the disease affects approximately 1 % of the general population. Clinical features of CD vary considerably. Intestinal symptoms are more common in young children. In older children extra intestinal manifestations affecting almost all organs are seen. IgA tTG antibody, upper GI endoscopy with histological analysis of multiple biopsies of the duodenum and in selected cases HLA DQ2 and DQ8 positivity and endomysial antibodies (EMA) are needed for diagnosis. Currently, the only treatment for CD is a life-long gluten-free diet (GFD). Strict avoidance of wheat, rye, barley and their derivatives will result in intestinal healing and relief of symptoms for the majority of individuals with CD. The GFD is simple in principle, however, completely eliminating all foods and ingredients containing wheat, rye, barley, and most commercial oats can be very challenging. Newly diagnosed CD children should undergo testing and treatment for micronutrient deficiencies specially iron, folic acid, vitamin D, and vitamin B12. Long-term monitoring and follow up of patients with CD is necessary. PMID:25172576

    Celiac disease (CD) is a permanent condition of gluten intolerance and a number of autoimmune diseases have been associated with it. In the past few years, a relation between CD and dilated cardiomyopathy (CM) was described in Europe and United States. The aim of this study was to evaluate the prevalence of CD among south Brazilian precardiac transplant patients with advanced CM. A total of 74 patients on a list for heart transplantation were evaluated for the presence CD. The presence of anti-endomisial antibody (IgA-EmA) was determined by indirect immunofluorescence and for the anti-transglutaminase antibody (IgA anti-h-tTG) by ELISA. Serologically positive patients were submitted to upper endoscopy with intestinal biopsy. Two individuals (2.63%) were positive for IgA-EmA and 5 (6.75%) for IgA anti-h-tTG; 1 (1.35%) had both tests positive. Histologic confirmation of CD occurred only in the IgA-EmA positive patients. In conclusion, data from the present study allows recommend the screening for CD in patients with CM using IgA-EmA test as the method of choice. PMID:16758314

    The prevalence of dyspepsia is up to 40% in population-based study. Functional dyspepsia is an exclusion diagnosis and it is classified as a chronic abdominal pain-related functional disorder, characterized by the presence of persistent or recurrent pain or discomfort centered in the upper abdomen, neither relief by defecation, nor association with the onset of a change in stool frequency or form. Celiac disease (CD) is a common autoimmune enteropathy, with a prevalence around 1% in the general population. Its diagnosis includes a serological screening and an upper gastrointestinal endoscopy with multiple biopsies. Gluten-free diet is the only effective treatment. CD diagnosis is often delayed in asymptomatic patients or in individuals with less clinical gastrointestinal symptoms. Several studies performed coeliac disease screening in patients with symptoms suggestive of dyspepsia, showing a biopsy-proved prevalence that ranged from 0.5% to 2%. The typical endoscopic markers of villous atrophy are not sufficiently sensitive, so some endoscopic techniques, such as “water immersion” and confocal endomicroscopy were proposed to improve the diagnostic sensitivity and target biopsies. A recent meta-analysis estimated that the prevalence of CD was higher in patients with dyspepsia, but not in a statistically significant way. However this assumption should be confirmed further larger studies. PMID:25332916

    Background and Aim. Although mercury is involved in several immunological diseases, nothing is known about its implication in celiac disease. Our aim was to evaluate blood and urinary levels of mercury in celiac patients. Methods. We prospectively enrolled 30 celiac patients (20 treated with normal duodenal mucosa and 10 untreated with duodenal atrophy) and 20 healthy controls from the same geographic area. Blood and urinary mercury concentrations were measured by means of flow injection inductively coupled plasma mass spectrometry. Enrolled patients underwent dental chart for amalgam fillings and completed a food-frequency questionnaire to evaluate diet and fish intake. Results. Mercury blood/urinary levels were 2.4 ± 2.3/1.0 ± 1.4, 10.2 ± 6.7/2.2 ± 3.0 and 3.7 ± 2.7/1.3 ± 1.2 in untreated CD, treated CD, and healthy controls, respectively. Resulting mercury levels were significantly higher in celiac patients following a gluten-free diet. No differences were found regarding fish intake and number of amalgam fillings. No demographic or clinical data were significantly associated with mercury levels in biologic samples. Conclusion. Data demonstrate a fourfold increase of mercury blood levels in celiac patients following a gluten-free diet. Further studies are needed to clarify its role in celiac mechanism. PMID:25802516

    Context Celiac disease (CD) is defined as a permanent intolerance to ingested gluten. The intolerance to gluten results in immune-mediated damage of small intestine mucosa manifested by villous atrophy and crypt hyperplasia. These abnormalities resolve with initiationa gluten-free diet. Evidence Acquisition PubMed, Ovid, and Google were searched for full text articles published between 1963 and 2012. The associated keywords were used, and papers described particularly the impact of celiac disease on severity of liver disorder were identified. Results Recently evidence has emerged revealingthat celiac disease not only is associated with small intestine abnormalities and malabsorption, but is also a multisystem disorder affecting other systems outside gastrointestinal tract, including musculo-skeletal, cardiovascular and nervous systems. Some correlations have been assumed between celiac and liver diseases. In particular, celiac disease is associated with changes in liver biochemistry and linked to alter the prognosis of other disorders. This review will concentrate on the effect of celiac disease and gluten-free diets on the severity of liver disorders. Conclusions Although GFD effect on the progression of CD associated liver diseases is not well defined, it seems that GFD improves liver function tests in patients with a hypertransaminasemia.

    Although many people have symptoms of celiac disease, it can take a while to diagnose. Villous atrophy may be present long before any gastrointestinal symptoms. An important point to acknowledge is that celiac disease could be identified earlier in some women with a positive family history. The disease also could be the cause of some women's reproductive problems. Primary care providers, using comprehensive history taking, are in the unique position to identify individuals who may have celiac disease, assist women in gaining knowledge about a gluten-free diet, order diagnostic testing, and refer to a gastroenterologist. The positive change in fertility with a simultaneous improvement of nutrient deficiencies shortly after adopting a gluten-free diet indicates a possible link between such nutrients and sex hormone function. High levels of homocysteine, which can negatively impact fertility, have also been linked to individuals with problems, such as celiac disease, that decrease vitamin B12 absorption. The purpose of this article is to review the literature and the evidence-based care guidelines for comprehensive screening, diagnostics, and pathophysiology of celiac disease, with a specific focus on the female reproductive system, anemia management, and gluten-free diet integration.

    Celiac disease has one of the strongest associations with HLA (human leukocyte antigen) class II markers of the known HLA-linked diseases. This association is primarily with the class II serologic specificities HLA-DR3 and -DQw2. We previously described a restriction fragment length polymorphism (RFLP) characterized by the presence of a 4.0-kilobase Rsa I fragment derived from an HLA class II beta-chain gene, which distinguishes the class II HLA haplotype of celiac disease patients from those of many serologically matched controls. We now report the isolation of this beta-chain gene from a bacteriophage genomic library constructed from the DNA of a celiac disease patient. Based on restriction mapping and differential hybridization with class II cDNA and oligonucleotide probes, this gene was identified as one encoding an HLA-DP beta chain. This celiac disease-associated HLA-DP beta-chain gene was flanked by HLA-DP alpha-chain genes and, therefore, was probably in its normal chromosomal location. The HLA-DP alpha-chain genes of celiac disease patients also were studied by RFLP analysis; 84% of HLA-DR3, -DQw2 patients had a 16-kb Xba I fragment that was present in only 36% of HLA-DR3, -DQw2 controls. Moreover, 79% of these patients had both alpha- and beta-chain polymorphisms in contrast to 27% of controls. Thus, celiac disease is associated with a subset of HLA-DR3, -DQw2 haplotypes characterized by HLA-DP alpha- and beta-chain gene RFLPs. Within the celiac-disease patient population, the joint segregation of these HLA-DP genes with those encoding the serologic specificities HLA-DR3 and -DQw2 indicates: (i) that the class II HLA haplotype associated with celiac disease is extended throughout the entire HLA-D region, and (ii) that celiac-disease susceptibility genes may reside as far centromeric on this haplotype as the HLA-DP subregion.

    BACKGROUND This study aimed to explore demographic characteristics and clinical presentations of celiac disease (CD) in Northeastern Iran. METHODS This was a cross-sectional retrospective study of 193 adults with CD who presented to Mashhad University Gastroenterology Clinic between 2008 and 2013. Patient data that included mode of presentation and the presence of any concomitant illnesses were collected. Intestinal biopsy and serum anti-tissue transglutaminase (anti-tTG) were used for diagnosis. Mucosal lesions were classified according to modified Marsh classification. RESULTS Overall, 132 females and 61 males, with a mean age at diagnosis of 32.6 ± 13.2 years were included. The patient's chief complaints in order of decreasing frequency were dyspepsia (24.6%), diarrhea (20%), anemia (12.8%), and flatulence (7.2%). Bone disease was seen (osteopenia, osteoporosis) in 30% of patients. A positive family history of CD was found in 17.9% of cases. There were 64% who had serum anti-tTG >200 units/ml and 78% had a Marsh classification grade 3 on duodenal biopsy. The histology grade (Marsh) did not show any correlation with anti-tTG serum levels, age, body mass index (BMI) or hemoglobin levels. CONCLUSION In Northeastern Iran, CD was seen more commonly in females and with non-diarrheal presentations. Abdominal discomfort, anemia and bone disease were most common primary presentations in this area. Histology grade showed no significant correlation with level of anti-tTG, BMI or hemoglobin levels. We suggest screening for CD in unexplained abdominal discomfort, bone disease and anemia. PMID:24872868

    Celiac disease (CD) is an immune-mediated enteropathy triggered by exposure to wheat gluten and similar proteins found in rye and barley that affects genetically susceptible persons. This immune-mediated enteropathy is characterized by villous atrophy, intraepithelial lymphocytosis, and crypt hyperplasia. Once thought a disease that largely presented with malnourished children, the wide spectrum of disease activity is now better recognized and this has resulted in a shift in the presenting symptoms of most patients with CD. New advances in testing, both serologic and endoscopic, have dramatically increased the detection and diagnosis of CD. While the gluten-free diet is still the only treatment for CD, recent investigations have explored alternative approaches, including the use of altered nonimmunogenic wheat variants, enzymatic degradation of gluten, tissue transglutaminase inhibitors, induction of tolerance, and peptides to restore integrity to intestinal tight junctions.

    Celiac disease is a chronic immune-mediated disorder with an important genetic component. To date, there are 57 independent association signals from 39 non-HLA loci, and a total of 66 candidate genes have been proposed. We aimed to scrutinize the functional implication of 45 of those genes by analyzing their expression in the disease tissue of celiac patients (at diagnosis/treatment) compared with non-celiac controls. Moreover, we investigated the SNP genotype effect in gene expression and performed coexpression analyses. Several genes showed differential expression among disease groups, most of them related to immune response. Multiple trans-eQTLs but only four cis-eQTLs were found, and surprisingly the genotype effect seems to be stimulus dependent as it differs among groups. Coexpression levels vary from higher to lower levels in active patients at diagnosis, treated patients and non-celiac controls respectively. A subset of 18 genes tightly correlated in both groups of patients but not in controls was identified. Interestingly, this subset of genes was influenced by the genotype of three SNPs. One of the SNPs, rs1018326 on chromosome two is on top of a known lincRNA whose function is not yet described, and whose expression seems to be upregulated in active disease when comparing biopsy pairs from the same individuals. Our results strongly suggest that the effects of disease-associated SNPs go far beyond the oversimplistic idea of transcriptional control at a nearby locus. Further investigations are needed to determine how each variant disrupts fine-tuning mechanisms in the genome that eventually lead to disease. PMID:25388004

    In the past it was believed that genetic predisposition and exposure to gluten were necessary and sufficient to develop celiac disease (CD). Recent studies however suggest that loss of gluten tolerance can occur at any time in life as a consequence of other environmental stimuli. Many environmental factors known to influence the composition of the intestinal microbiota are also suggested to play a role in the development of CD. These include birthing delivery mode, infant feeding, and antibiotic use. To date no large-scale longitudinal studies have defined if and how gut microbiota composition and metabolomic profiles may influence the loss of gluten tolerance and subsequent onset of CD in genetically-susceptible individuals. Here we describe a prospective, multicenter, longitudinal study of infants at risk for CD which will employ a blend of basic and applied studies to yield fundamental insights into the role of the gut microbiome as an additional factor that may play a key role in early steps involved in the onset of autoimmune disease.

    Celiac disease (CD) is a permanent intolerance to gluten characterized by destructions of the small intestinal villi and malabsorption. The gluten-free diet (GFD) results in healing of the mucosa, resolution of the malabsorpitive states, and reversal of great part of CD effects. Among the extradigestive complications associated with CD, unexplained infertility has been reported since the 70's. The prevalence of CD among women with unexplained infertility is 2.5-3.5%, higher, although not always significantly, than control population. To date, it is widely accepted that untreated CD represents a risk for abortion, low birth weight babies and short-breast feeding period. These features can be corrected by GFD. Some discrepancies could stem from the heterogeneity of the studies. Regarding a potential pathogenic mechanism, since CD causes malabsorption of folic acid and other nutrients, this pathway has been proposed to explain the unfavourable outcomes of pregnancy. However, this remains a speculation. In conclusion, each woman with unexplained infertility should be screened for CD. PMID:17592443

    Celiac disease is triggered by partially digested gluten proteins. Enzyme therapies that complete protein digestion in vivo could support a gluten-free diet, but the barrier to completeness is high. Current options require enzyme amounts on the same order as the protein meal itself. In this study, we evaluated proteolytic components of the carnivorous pitcher plant (Nepenthes spp.) for use in this context. Remarkably low doses enhance gliadin solubilization rates, and degrade gliadin slurries within the pH and temporal constraints of human gastric digestion. Potencies in excess of 1200:1 (substrate-to-enzyme) are achieved. Digestion generates small peptides through nepenthesin and neprosin, the latter a novel enzyme defining a previously-unknown class of prolyl endoprotease. The digests also exhibit reduced TG2 conversion rates in the immunogenic regions of gliadin, providing a twin mechanism for evading T-cell recognition. When sensitized and dosed with enzyme-treated gliadin, NOD/DQ8 mice did not show intestinal inflammation, when compared to mice challenged with only pepsin-treated gliadin. The low enzyme load needed for effective digestion suggests that gluten detoxification can be achieved in a meal setting, using metered dosing based on meal size. We demonstrate this by showing efficient antigen processing at total substrate-to-enzyme ratios exceeding 12,000:1. PMID:27481162

    Background: The prevalence of irritable bowel syndrome (IBS) in the community is 10%–20% and have symptom based diagnostic criteria. Many symptoms of celiac disease (CD) with 1% prevalence in some communities can mimic IBS. Sensitive and specific serologic tests of CD can detect asymptomatic cases. The purpose of this study was to compare the level of anti-tissue-transglutaminase (tTG) IgA in IBS patients and controls group. Materials and Methods: This case-control study was performed at a University hospital in which 107 patients with IBS who met the Rome II criteria for their diagnosis were compared with 126 healthy age and sex-matched controls. Both groups were investigated for CD by analysis of their serum tTG IgA antibody with human recombinant antigen. Titers were positive containing over 10u/ml and borderline if they were between 4 and 10 u/ml. Result: 86 percent of IBS patients were female. The mean antibody level was 0.837 u/ml in IBS group and 0.933 u/ml in control group without any significant difference. Discussion and Conclusion: Results of this study may intensify disagreement on the situation of CD in IBS patients. PMID:23826010

    A 27-year-old male started to have his ankles swollen during his military service. He was examined at a military hospital where electromyoneurography showed the signs of distal sensory-motor polyneuropathy with axon demyelinization and weak myopathic changes, whereas histopathological examination of gastrocnemius muscle biopsy revealed some mild and nonspecific myopathy. Besides, he was found to have subcutaneous ankle tissue edemas and hypertransaminasemia. Due to these reasons, he was dismissed from the military service and examined at another hospital where bone osteodensitometry revealed low bone mineral density of the spine. However, his medical problems were not resolved and after the second discharge from hospital he was desperately seeing doctors from time to time. Finally, at our institution he was shown to have celiac disease (CD) by positive serology (antitissue transglutaminase and antiendomysial antibodies) and small bowel mucosal histopathological examination, which showed total small bowel villous atrophy. Three months after the initiation of gluten-free diet, his ankle edema disappeared, electromyoneurographic signs of polyneuropathy improved and liver aminotransferases normalized. Good knowledge of CD extraintestinal signs and serologic screening are essential for early CD recognition and therapy. PMID:17552018

    Celiac disease is triggered by partially digested gluten proteins. Enzyme therapies that complete protein digestion in vivo could support a gluten-free diet, but the barrier to completeness is high. Current options require enzyme amounts on the same order as the protein meal itself. In this study, we evaluated proteolytic components of the carnivorous pitcher plant (Nepenthes spp.) for use in this context. Remarkably low doses enhance gliadin solubilization rates, and degrade gliadin slurries within the pH and temporal constraints of human gastric digestion. Potencies in excess of 1200:1 (substrate-to-enzyme) are achieved. Digestion generates small peptides through nepenthesin and neprosin, the latter a novel enzyme defining a previously-unknown class of prolyl endoprotease. The digests also exhibit reduced TG2 conversion rates in the immunogenic regions of gliadin, providing a twin mechanism for evading T-cell recognition. When sensitized and dosed with enzyme-treated gliadin, NOD/DQ8 mice did not show intestinal inflammation, when compared to mice challenged with only pepsin-treated gliadin. The low enzyme load needed for effective digestion suggests that gluten detoxification can be achieved in a meal setting, using metered dosing based on meal size. We demonstrate this by showing efficient antigen processing at total substrate-to-enzyme ratios exceeding 12,000:1. PMID:27481162

  19. Non-dietary forms of treatment for adult celiac disease

    At present, treatment for celiac disease includes a strict gluten-free diet. Compliance, however, is difficult and gluten-free food products are costly, and, sometimes very inconvenient. A number of potential alternative measures have been proposed to either replace or supplement gluten-free diet therapy. In the past, non-dietary forms of treatment were used (e.g., corticosteroids) by some clinicians, often to supplement a gluten-free diet in patients that appeared to be poorly responsive to a gluten-free diet. Some of new and novel non-dietary measures have already advanced to a clinical trial phase. There are still some difficulties even if initial studies suggest a particularly exciting and novel form of non-dietary treatment. In particular, precise monitoring of the response to these agents will become critical. Symptom or laboratory improvement may be important, but it will be critical to ensure that ongoing inflammatory change and mucosal injury are not present. Therapeutic trials will be made more difficult because there is already an effective treatment regimen. PMID:24199026

    Celiac disease (CD) is a genetically determined autoimmune enteropathy, induced by gluten ingestion. To date, different prevalences of CD in children with epilepsy have been reported. The aim of this study was to determine CD prevalence in our patients with epilepsy, using anti-tissue transglutaminase (tTG) antibodies as a screening test. One hundred twenty-five children (72 girls, 53 boys; age range: 2-18 years, mean age: 10.51 +/- 3.53) with idiopathic epilepsy from South East Serbia were tested for immunoglobulin (IgA) tTG antibodies. All positive patients were offered endoscopic small bowel biopsy. Biopsies were examined histopathologically in order to confirm the CD diagnosis. The control group consisted of 150 healthy children. Three patients with epilepsy were positive for IgA tTG antibodies. In all of them, small bowel biopsy was performed, and only one was proven to have CD by histopathology (Marsh IIIa grade). The prevalence of biopsy-proven CD in children with epilepsy was not significantly higher in the study group compared to controls (0.8% vs.0.6%, p > 0.05). The results of this study indicate that children with idiopathic epilepsy from our region should not be routinely tested for CD. PMID:23094534

    Celiac disease is the most common autoimmune enteropathy in Western countries, and is usually associated with a good response to the gluten free diet and an excellent prognosis. However, a minority of patients develop complications of the disease, such as refractory celiac disease, ulcerative jejunoileitis and neoplastic complications such as adenocarcinoma of the small bowel and enteropathy associated T cell lymphoma. Neoplastic complications described in association with celiac disease have a high mortality rate, due to their aggressive behavior and to the usual advanced stage at the time of diagnosis. In recent years, the detection of small bowel lesions has dramatically improved thank to the availability of highly performing radiologic and endoscopic techniques. The diagnostic delay of malignant complications in patients with celiac disease may be improved by establishing a pragmatic flowchart for the identification and follow up of "at risk" patients. We performed a comprehensive review of the articles published on this issue in order to promote a roadmap to be applied when facing with celiac patients with suspected small bowel complications.

    Celiac disease (CD) is a unique autoimmune disorder that occurs in genetically susceptible individuals after the ingestion of gluten, a protein found in wheat and some other cereals. The immunologically based inflammation induces atrophy of the villous structure of the jejunum, leading to malabsorption of variable severity. Subclinical and nonspecific forms of CD have been found to be increasingly common with a classic presentation of malabsorption syndrome (reference A). We present a case of OCD (obsessive compulsive disorder) in combination with depressive symptoms with the further complication of eating disorder not otherwise specified, in an adolescent male, for whom psychiatry was consulted because of treatment-refractory weight loss. We compare the elements of the case to other descriptions in the current, English language professional literature. Our literature review includes multiple search terms for the professional journals including, but not limited to, psychiatric comorbidities in celiac disease, behavioral disturbances of celiac disease, celiac disease in psychiatry, etc., to establish a possible association of psychiatric disorders, especially obsessive compulsive disorder and Celiac disease.

    Excessive flatulence which impairs social performance in patients is one of the common reasons for referrals to gastroenterology clinics. Celiac Disease is a rare but important cause of increased intestinal gas (bloating) and if not diagnosed, patients face complications such as malabsorption, anemia, osteoporosis and even intestinal lymphoma. This study aimed to determine the frequency of Celiac Disease in patients with excessive flatulence. One hundred and fifty patients with a chief complaint of experiencing flatulence more than 15 times a day and lasting for three months were referred to the gastroenterology clinic of Rasoul-e-Akram Teaching Hospital. Serological tests for Celiac Disease, Anti TTG Ab (IgA-IgG) were requested and the patients with positive tests underwent upper GI endoscopy. Biopsies of the second part of the duodenum were then sent to the laboratory. From one hundred and thirty patients who completed the study, 92 (70.7%) were female. Mean age of the patients was 32 ± 13 years. Anti TTG Ab was found in 5 patients (3.85%). Only 2 patients (1.5%) had a documented positive pathology for Celiac Disease. According to the results of this study and other studies, we conclude that Celiac Disease is an uncommon etiology for excessive flatulence but it is of importance to investigate it in excessive flatulence patients.

    To determine the prevalence of celiac disease in children and adolescents with nonsyndromic intellectual disability, we investigated serum levels of tissue transglutaminase antibody and total IgA from 232 children with nonsyndromic intellectual disability and in a healthy control group of 239 children. Study participants who were positive for tissue transglutaminase antibody underwent a duodenal biopsy. A total of 3 patients in the nonsyndromic intellectual disability group (5.45%) and 1 in the control group (0.41%) had positive serum tissue transglutaminase antibody (P > .05). Duodenal biopsy confirmed celiac disease in only 1 patient who had nonsyndromic intellectual disability. In this present study, children with nonsyndromic intellectual disability did not exhibit a higher celiac disease prevalence rate compared with healthy controls. Therefore, we suggest that screening test for celiac disease should not be necessary as a part of the management of mild and moderate nonsyndromic intellectual disability. However, cases of severe nonsyndromic intellectual disability could be examined for celiac disease. PMID:26078418

    Until 1970s, celiac disease (CD) was considered to be an uncommon disease except in Western Europe. The global epidemiology of CD continues to evolve with improvement in the diagnostic tests, simplification of the diagnostic criteria and increase in awareness about the disease. The Asian region is currently at the crossroads of the frontier of knowledge and awareness of CD. In many Asian nations, CD is still considered to be either nonexistent or very rare. A notable exception is India, where CD has been well recognized, especially in the northern part, and 2 population-based studies have revealed a prevalence of 0.3-1.04%. Initial reports from Malaysia, China, Japan and Singapore suggest the existence of CD in these countries. Furthermore, a meta-analysis of the predisposing factors predicts a high probability of occurrence of CD in fair numbers in China. There are no formal reports on CD from Malaysia, Indonesia, Korea, Taiwan and many other nations in this region. With the impending CD epidemic in Asia, there are many challenges. Some of the efforts which are required include determination of prevalence of CD across the region, spreading of awareness among physicians and patients, training of dieticians for proper counseling and supervision of patients, creation of gluten-free food infrastructure in the food supply and creation of patient advocacy organizations. Although the absolute number of patients with CD at present is not very large, this number is expected to increase over the next few years/decades. It is thus appropriate that the medical community across Asia define the extent of the problem and get prepared to handle the impending CD epidemic. PMID:25925919

    Introduction: Aims: to measure the association between Celiac Disease (CD) and affective disorders, particularly Bipolar Disorder (BD), since it has not been studied yet, and to measure how much the quality of life (QoL) of a person with CD is affected by comorbidity with these disorders. Methods: Design: Case-control study. Cases: 60 consecutive patients with CD. Controls: 240 subjects without CD, randomly selected after sex- and age-matching from a database of an epidemiological study. Psychiatric diagnoses according to DSM-IV carried out by physicians using structured interview tools (ANTAS-SCID). QoL was measured by means of SF-12. Results: The lifetime prevalence of Major Depressive Disorder (MDD) was higher in CD than in controls (30.0% vs 8.3%, P<0.0001) as well as Panic Disorder (PD) (18.3% vs 5.4%, P<0.001) and BD (4.3% vs 0.4%, P<0.005). Patients with CD show a lower mean score than controls on SF12 (35.8±5.7 vs. 38.2±6.4; p=0.010), but those without comorbidity with MDD, PD and BD do not. The attributable burden of CD in worsening QoL - when comorbid with these disorders - was found comparable to that of serious chronic diseases like Wilson’s Disease, and lower than Multiple Sclerosis only. Conclusion: MDD, PD and BD are strictly associated with CD. The comorbidity with these disorders is the key determinant of impaired quality of life in CD. Thus a preventive action on mood and anxiety disorders in patients suffering from CD is required. Moreover a screening for CD in people with affective disorders and showing key symptoms or family history of CD is recommended. PMID:26962323

    Aim Celiac disease (CD) is a multifactorial autoimmune disease induced by ingestion of gluten in genetically predisposed individuals. Despite technological progress, the diagnosis of CD is still based on duodenal biopsy as it was 50 years ago. In this study we analysed the expression of CD-associated genes in small bowel biopsies of patients and controls in order to explore the multivariate pathway of the expression profile of CD patients. Then, using multivariant discriminant analysis, we evaluated whether the expression profiles of these genes in peripheral blood monocytes (PBMs) differed between patients and controls. Participants Thirty-seven patients with active and 11 with treated CD, 40 healthy controls and 9 disease controls (Crohn’s disease patients) were enrolled. Results Several genes were differentially expressed in CD patients versus controls, but the analysis of each single gene did not provided a comprehensive picture. A multivariate discriminant analysis showed that the expression of 5 genes in intestinal mucosa accounted for 93% of the difference between CD patients and controls. We then applied the same approach to PBMs, on a training set of 20 samples. The discriminant equation obtained was validated on a testing cohort of 10 additional cases and controls, and we obtained a correct classification of all CD cases and of 91% of the control samples. We applied this equation to treated CD patients and to disease controls and obtained a discrimination of 100%. Conclusions The combined expression of 4 genes allows one to discriminate between CD patients and controls, and between CD patients on a gluten-free diet and disease controls. Our results contribute to the understanding of the complex interactions among CD-associated genes, and they may represent a starting point for the development of a molecular diagnosis of celiac disease.

    Type 1 diabetes (T1D) and celiac disease (CD) are autoimmune diseases with clinical and pathogenic overlap. The mean prevalence of CD in patients with T1D is about 8%. Classic intestinal symptoms of CD may not be present in T1D leading to the recommendation for active case finding in this higher risk group. Screening is done with sensitive and specific serologies including tissue transglutaminase (tTG) IgA and deaminated gliadin peptide (DGP) IgA and IgG. Positive serologies are confirmed by the presence of villous atrophy and increased intraepithelial lymphocytes on duodenal biopsy. A strict gluten free diet is recommended, although this can pose challenges for T1D patients who already have dietary restrictions. In aggregate, it appears as if the gluten free diet may help T1D management. T1D and CD have overlapping genetic and environmental risk factors. Among these, non-HLA genetic factors and the gut microbiome are among recent developments that will be discussed in this review. PMID:24952108

    Authors report a case of patient suffering from haemophilia A and hepatitis C virus infection acquired probably after blood transfusions and substitution factors application. He was treated with pegylated interferon alpha and ribavirin, with the development of malabsorption symptoms during the therapy. Celiac disease was established by histological, histochemical and serological examinations. oth, interferon alpha and ribavirin treatment as well as virus of hepatitis C may trigger coeliac disease in genetically predisposed individuals. The immunological mechanism of celiac disease include balance disruption between Th1 and Th2 immunological response with Th1 predominance. Only few similar cases have been published in the professional literature to date. Development of celiac disease during interferon alpha therapy with haemophilia A was not published until now (Fig. 3, Ref. 13). PMID:21692415

    The study included 132 women (average age 38.5 +/- 1.17 years) with HC observed in the CSRIG from 2000 to 2010. Comparison group consisted of 105 women (average age 38.7 +/- 1.6 years) mainly with functional bowel disorders (irritable bowel syndrome, functional constipation, functional meteorism, inert colon). Take into account the information relating to obstetric and gynecological history, Physical and laboratory signs of malabsorption syndrome (MS), studies of antibodies to alpha-gliadin immunoglobulin (IG), Class A (AHA) and tissue transglutaminase (AtTG). Reproductive disorders in women with celiac disease are significantly more frequently than in women with functional bowel disease. One of the causes of reproductive disorders in patients with HC might be malabsorption disorders of essential nutrients in the small intestine. The presence of reproductive disorders should be considered as a risk factor for celiac disease, so these women should be screened for celiac disease. PMID:22364010

    Celiac disease (CD) is an autoimmune enteropathy induced by the ingestion of gluten in genetically predisposed individuals who carry the HLA-DQ2 or -DQ8 alleles. The immune response is abnormal in celiac disease with small intestinal epithelial damage via CD8+CD4- intraepithelial lymphocytes. The etiology is multifactorial involving genetic and environmental factors, an abnormal immune response, and intestinal dysbiosis. The innate and acquired T-cell mediated immunity play important roles in the pathogenesis of this disease, particularly CD4+ Th17 cells, which have been shown to have critical functions in host defense against bacterial pathogens and in the inflammatory responses to deamidated gluten peptides. We review what is known about the interaction between immune system and intestinal microbiota in the pathogenesis of celiac disease. PMID:25926936

    BACKGROUND Celiac disease (CD) can be associated with a variety of extraintestinal manifestations, including neurological diseases. A new neurological correlation has been found between CD and sensorineural hearing loss (SNHL). OBJECTIVE To verify the association between SNHL and CD, and to establish whether the neurological hearing impairment in CD is related to nonorgan-specific and antineuronal antibodies, as well as the presence of autoimmune disorders. METHODS A sample of 59 consecutive biopsy- and serologically proven CD patients were studied. Among CD patients, 11 were newly diagnosed and 48 were on a gluten-free diet. Hearing function was assessed by audiometric analysis in all CD patients as well as in 59 age- and sex-matched controls. Patients were tested for a panel of immune markers including nonorgan-specific autoantibodies and antineuronal antibodies. RESULTS SNHL was detected in five CD patients (8.5%) and in two controls (3.4%). In one patient, the SNHL was bilateral, whereas the remaining four had a monolateral impairment. The prevalence of SNHL was not significantly different between CD patients and controls. At least one of the antibodies tested for was positive in two of the five CD patients with SNHL and in 12 of the 54 CD patients without SNHL. Antineuronal antibodies to central nervous system antigens were consistently negative in the five CD patients with SNHL. Only one of the five CD patients with SNHL had Hashimoto thyroiditis. CONCLUSIONS SNHL and CD occur coincidentally. Hearing function should be assessed only in CD patients with clinical signs of hearing deficiency. PMID:19668795

    Background Celiac disease (CD) is a chronic inflammatory disease of the small intestine triggered by gluten ingestion. The objective of this study is to describe our experience with CD children in Kuwait. Methods The records of children with CD seen in the pediatric gastroenterology unit between February 1998 and December 2010 were retrospectively reviewed. Patients were referred because of symptoms or positive CD antibody screening of a high-risk group (type 1 diabetes and Down syndrome). Results Forty-seven patients were diagnosed: 53% were symptomatic and 47% were identified by screening. The median age at diagnosis was 66 (range 7–189) months. All cases were biopsy-proven except one. The symptomatic patients were significantly younger than those identified following screening (P<0.004). In the whole group, 66% were females and 77% were Kuwaitis; 9% had a positive family history of CD. The estimated cumulative incidence was 6.9/105. The median duration of symptoms before diagnosis was 8.5 (range 2–54) months. Failure to thrive was the most common presenting complaint (72%) followed by diarrhea (64%) and abdominal distension (56%). Atypical manifestations were seen in 60% of patients. Underweight and short stature were confirmed in 19% and 17% of patients, respectively. Overweight and obesity were detected in 14% and 6%, respectively. CD serology was based on a combination of antiendomysial and antigliadin antibodies. The median follow up was 24 (range 12–144) months. All patients were commenced on a gluten free diet, but good compliance was only achieved in 78%. Conclusion The low frequency of childhood CD in Kuwait could probably be attributed to either an underestimation of the atypical presentations or failure of proper screening. Also, adherence to a gluten free diet is a major problem in our population. PMID:25565879

    Oats in a gluten-free diet increase the diet's nutritional value, but their use remains controversial. Contamination with prolamins of other cereals is frequent, and some clinical and experimental studies support the view that a subgroup of celiac patients may be intolerant to pure oats. Thus, this issue is more complex than previously suggested. In order to produce oats that are safe for all celiac patients, the following topics should be addressed: selection of oat cultivars with low avenin content, research on such recombinant varieties of oats, development of assay methods to detect avenins in oat products, guidelines for the agricultural processing of oats and the manufacture of oat products, as well as guidelines for following up with celiac patients who consume oats.

    Introduction The only treatment for celiac disease (CD) is life-long adherence to a gluten-free diet (GFD). Noncompliance is associated with signs and symptoms of celiac disease, yet long-term adherence rates are poor. It is not known how the burden of the GFD compares to other medical treatments, and there are limited data on the socio-economic factors influencing treatment adherence. In this study we compared treatment burden and health state in CD compared with other chronic illnesses and evaluated the relationship between treatment burden and adherence. Methods A survey was mailed to participants with: CD, gastroesophageal reflux disease (GERD), irritable bowel syndrome (IBS), inflammatory bowel disease (IBD), hypertension (HTN), diabetes mellitus (DM), congestive heart failure (CHF), and end stage renal disease on dialysis (ESRD). Surveys included demographic information and visual analog scales measuring treatment burden, importance of treatment, disease-specific and overall health status. Results We collected surveys from 341 celiac and 368 non-celiac participants. Celiac participants reported high treatment burden, greater than participants with GERD or HTN and comparable to ESRD. Conversely, patients with CD reported the highest health state of all groups. Factors associated with high treatment burden in CD included poor adherence, concern regarding food cost, eating outside the home, higher income, lack of college education and time limitations in preparing food. Poor adherence in CD was associated with increased symptoms, income, and low perceived importance of treatment. Discussion Participants with CD have high treatment burden but also excellent overall health status in comparison with other chronic medical conditions. The significant burden of dietary therapy for celiac disease argues for the need for safe adjuvant treatment as well as interventions designed to lower the perceived burden of the GFD. PMID:24980880

    Background: Celiac disease is an enteropathy characterized by gluten sensitivity and broad clinical aspect. Has a multifactorial cause and depends on genetic, immunological and environmental factors for its development. The genetic influence is given mostly by the human leukocyte antigens HLA DQ2 and DQ8. Aim: To evaluate the prevalence of human leukocyte antigens DQ2 and DQ8 in three different groups: patients with celiac disease, first-degree relatives and the general population. Method: Retrospective analysis that evaluated serologic and endoscopic data of 74 patients with celiac disease and 109 non-celiac, which were subdivided into two subgroups: non-celiac who had first-degree relatives with celiac and non-celiac who did not. All patients underwent laboratory examination for screening genetic sensitivity given by HLA DQ2 and HLA DQ8 by. Results: The presence of HLA DQ2 and DQ8 was identified in 98,4% of 74 celiac patients, of which 79,7% had only HLA DQ2; 8,1% had only HLA DQ8 and 10,8% had both antigens histocompatibility. In the group of relatives of celiac patients, were included 29 patients; among them, 89,6% had HLA DQ2 and/or DQ8; 76% only the HLA DQ2, 10,3% only HLA DQ8 and 3,4% presented both human leukocyte antigens (HLA). Conclusion: HLA DQ2/DQ8 was present in 98,4% of celiac patients; 89,6% relatives of celiac family and in 55,4% of people from the general population without family celiac. PMID:26537142

    Introduction: Idiopathic Pulmonary Hemosiderosis (IPH) is a rare cause of alveolar hemorrhage, which is seen primarily in childhood. Celiac disease is defined as a chronic, immune-mediated enteropathy of the small intestine, caused by exposure to dietary gluten in genetically pre-disposed individuals. Association of IPH and celiac disease is known as Lane Hamilton syndrome. There are limited number of case reports of this syndrome in literature. Case Presentation: Although there were no growth and developmental delay and gastrointestinal symptoms like chronic diarrhea, chronic constipation, vomiting, abdominal bloating and pain in the two patients with IPH, they were diagnosed with Lane Hamilton Syndrome. After initiation of gluten-free diet, their IPH symptoms disappeared and hemoglobin levels were observed to return to normal. Conclusions: Even if there were no gastrointestinal symptoms in a patient with IPH, celiac disease should be investigated. These patients may benefit from gluten free diet and IPH symptoms may disappear. PMID:26495097

  18. Body mass index is not a reliable tool in predicting celiac disease in children

    PubMed Central

    2014-01-01

    Background Untreated celiac disease is traditionally believed to be associated with malabsorption and underweight. However, studies describing body mass index (BMI) in individuals at the time of diagnosis have shown contradictory results. We investigated the differences in weight, height, and BMI in 12- year-old children with screening-detected celiac disease compared to their healthy peers. Methods In a population-based screening study of 12,632 12-year-old children, blood samples were analyzed for markers of celiac disease. Children with elevated markers were referred for a small bowel biopsy. Weight and height were measured in 239 out of 242 children with screening-detected celiac disease (57.3% girls) and in 12,227 children without celiac disease (48.5% girls). BMI was categorized according to the International Obesity Task Force. Age- and sex-specific cut-off points for underweight, normal weight, and overweight were used. Results Children with celiac disease weighed less and were shorter than their peers (median weight 45.2 kg, interquartile range (IQR) 40.2–52.2 kg vs. 47.0 kg, IQR 41.1–54.4 kg, respectively, p = 0.01; median height 156.5 cm, IQR 151.0–162.0 cm vs. 157.5 cm, IQR 152.0–163.0 cm, respectively, p = 0.04). In comparing those with celiac disease to their healthy peers, 4.2% vs. 5.2% were underweight, 82.0% vs. 72.8% were normal weight, and 13.8% vs. 21.9% were overweight, respectively. There was no association between being underweight and the risk of having undiagnosed celiac disease (Odds ratio (OR) 1.3, 95% CI 0.7–2.4), but the risk was significantly lower among overweight children (OR 0.56, 95% CI 0.4–0.8). Median BMI was slightly lower among the children with screening-detected celiac disease compared to their healthy peers (18.6 kg/m2, IQR 17.1–19.8 kg/m2 vs. 18.8 kg/m2, IQR 17.2–21.1 kg/m2, respectively, p = 0.05), but most of the celiac disease cases had a normal BMI.

    Many celiac disease patients tolerate oats, but limited data are available on its long-term consumption. This was evaluated in the present study, focusing on small-bowel mucosal histology and gastrointestinal symptoms in celiac adults maintaining a strict gluten-free diet with or without oats. Altogether 106 long-term treated celiac adults were enrolled for this cross-sectional follow-up study. Daily consumption of oats and fiber was assessed, and small-bowel mucosal morphology and densities of CD3+, αβ+ and γσ+ intraepithelial lymphocytes determined. Gastrointestinal symptoms were assessed by a validated Gastrointestinal Symptom Rating Scale questionnaire. Seventy (66%) out of the 106 treated celiac disease patients had consumed a median of 20 g of oats (range 1-100 g) per day for up to eight years; all consumed oat products bought from general stores. Daily intake and long-term consumption of oats did not result in small-bowel mucosal villous damage, inflammation, or gastrointestinal symptoms. Oat-consumers had a significantly higher daily intake of fiber than those who did not use oats. Two thirds of celiac disease patients preferred to use oats in their daily diet. Even long-term ingestion of oats had no harmful effects. PMID:24201240

    OBJECTIVES The prevalence of celiac disease (CD) varies greatly, potentially because of incomplete ascertainment of cases and small study samples with limited statistical power. Previous reports indicate that the incidence of CD is increasing. We examined the prevalence of CD in a well-defined US county. METHODS Population-based study in Olmsted County, Minnesota, US. Using the infrastructure of the Rochester Epidemiology Project, medical, histopathology, and CD serology records were used to identify all new cases of CD in Olmsted County since 2000. Age- and sex-specific and adjusted (to the US white 2000 population) incidence rates for CD were estimated. Clinical presentation at diagnosis was also assessed. RESULTS Between 2000 and 2010, 249 individuals (157 female or 63%, median age 37.9 years) were diagnosed with CD in Olmsted County. The overall age- and sex-adjusted incidence of CD in the study period was 17.4 (95% confidence interval [CI] = 15.2–19.6) per 100,000 person-years, increasing from 11.1 (95% CI=6.8–15.5) in 2000–2001 to 17.3 (95% CI=13.3–21.3) in 2008–2010. The temporal trend in incidence rates was modeled as a two-slope pattern, with the incidence leveling off after 2004. Based on the two classic CD symptoms of diarrhea and weight loss, the relative frequency of classical CD among incident cases decreased over time between 2000 and 2010 (p=0.044). CONCLUSION The incidence of CD has continued to increase in the past decade in a North American population. PMID:23511460

    Background Although the prevalence of celiac disease in the USA approaches 1%, most cases are undiagnosed, in part, because of low adherence to the recommendation of submitting at least four specimens during duodenal biopsy. We aimed to determine whether physician and practice characteristics are associated with adherence to this recommendation. Materials and methods We used a large national pathology database to identify all adult patients who underwent duodenal biopsy during 2006–2009. Hierarchical modeling was used to determine whether procedure volume, the number of gastroenterologists per endoscopy suite, and the number of gastroenterologists per capita of the zip code of the practice were associated with adherence. Results We identified 92 580 patients (67% female, mean age 53.5 years) who met our inclusion/exclusion criteria. Specimens were submitted by 669 gastroenterologists from 200 endoscopy suites, located in 191 zip codes, with a mean of 3.4 gastroenterologists per suite. On multivariate analysis, a higher procedure volume was associated with a decreased adherence [odds ratio (OR) for each additional 100 procedures, 0.92; 95% confidence interval (CI), 0.88–0.97; P = 0.002]. An increased adherence was reported for gastroenterologists working at suites with higher numbers of gastroenterologists (OR for each additional gastroenterologist, 1.08; 95% CI, 1.04–1.13; P < 0.001) but not for a higher gastroenterologist density in the zip code of the practice (OR for each additional gastroenterologist per capita, 1.01; 95% CI, 0.99–1.03; P = 0.21). Conclusion High-volume physicians exhibit lower rates of adherence to biopsy guidelines, possibly because of the additional time required to submit at least four specimens. In contrast, a greater number of endoscopists working in an endoscopy suite are associated with an increased adherence, possibly because of peer education. PMID:23995767

    Objective The protein Hwp1, expressed on the pathogenic phase of Candida albicans, presents sequence analogy with the gluten protein gliadin and is also a substrate for transglutaminase. This had led to the suggestion that C. albicans infection (CI) may be a triggering factor for Celiac disease (CeD) onset. We investigated cross-immune reactivity between CeD and CI. Methods Serum IgG levels against recombinant Hwp1 and serological markers of CeD were measured in 87 CeD patients, 41 CI patients, and 98 healthy controls (HC). IgA and IgG were also measured in 20 individuals from each of these groups using microchips sensitized with 38 peptides designed from the N-terminal of Hwp1. Results CI and CeD patients had higher levels of anti-Hwp1 (p=0.0005 and p=0.004) and anti-gliadin (p=0.002 and p=0.0009) antibodies than HC but there was no significant difference between CeD and CI patients. CeD and CI patients had higher levels of anti-transglutaminase IgA than HC (p=0.0001 and p=0.0039). During CI, the increase in anti-Hwp1 paralleled the increase in anti-gliadin antibodies. Microchip analysis showed that CeD patients were more reactive against some Hwp1 peptides than CI patients, and that some deamidated peptides were more reactive than their native analogs. Binding of IgG from CeD patients to Hwp1 peptides was inhibited by γIII gliadin peptides. Conclusions Humoral cross-reactivity between Hwp1 and gliadin was observed during CeD and CI. Increased reactivity to Hwp1 deamidated peptide suggests that transglutaminase is involved in this interplay. These results support the hypothesis that CI may trigger CeD onset in genetically-susceptible individuals. PMID:25793717

    Background Celiac disease (CD) is a lifelong disorder. Patients are at increased risk of complications and comorbidity. Objectives We conducted a review of the literature on patient support and information in CD and aim to issue recommendations about patient information with regards to CD. Methods Data source: We searched PubMed for English-language articles published between 1900 and June 2014, containing terms related to costs, economics of CD, or education and CD. Study selection: Papers deemed relevant by any of the participating authors were included in the study. Data synthesis: No quantitative synthesis of data was performed. Instead we formulated a consensus view of the information that should be offered to all patients with CD. Results There are few randomized clinical trials examining the effect of patient support in CD. Patients and their families receive information from many sources. It is important that health care personnel guide the patient through the plethora of facts and comments on the Internet. An understanding of CD is likely to improve dietary adherence. Patients should be educated about current knowledge about risk factors for CD, as well as the increased risk of complications. Patients should also be advised to avoid other health hazards, such as smoking. Many patients are eager to learn about future non-dietary treatments of CD. This review also comments on novel therapies but it is important to stress that no such treatment is available at present. Conclusion Based on mostly observational data, we suggest that patient support and information should be an integral part of the management of CD, and is likely to affect the outcome of CD.

    Background and Objectives Celiac disease (CD) is a chronic autoimmune disorder induced by dietary gluten intake by individuals who are genetically sensitive. Many studies report an increased risk of cardiovascular diseases in such patients. The aim of this study is to assess aortic elasticity properties in patients with CD that may be associated with an increased risk of cardiovascular disease. Subjects and Methods Eighty-one patients diagnosed with CD by antibody test and biopsy and 63 healthy volunteers were included in this prospective study. Electrocardiographic and echocardiographic examinations were performed. Results The CD group did not have any differences in the conventional echocardiographic parameters compared to the healthy individuals. However, patients in the CD group had an increased aortic stiffness beta index (4.3±2.3 vs. 3.6±1.6, p=0.010), increased pressure strain elastic modulus (33.6±17.0 kPa vs. 28.5±16.7 kPa, p=0.037), decreased aortic distensibility (7.0±3.0×10-6 cm2/dyn vs. 8.2±3.6×10-6 cm2/dyn, p=0.037), and similar aortic strain (17.9±7.7 vs. 16.0±5.5, p=0.070) compared to the control group. Patients with CD were found to have an elevated neutrophil/lymphocyte ratio compared to the control group (2.54±0.63 vs. 2.24±0.63, p=0.012). However, gluten-free diet and neutrophil/lymphocyte ratio were not found to be associated with aortic elasticity. Conclusion Patients with CD had increased aortic stiffness and decreased aortic distensibility. Gluten-free diet enabled the patients with CD to have a reduction in the inflammatory parameters whereas the absence of a significant difference in the elastic properties of the aorta may suggest that the risk of cardiovascular disease persists in this patient group despite a gluten-free diet.

    The prevalence of celiac disease autoimmunity or tissue transglutaminase autoantibodies (TGA) amongst patients with type 1 diabetes (T1D) and autoimmune thyroid disease (AITD) in the Chinese population remains unknown. This study examined the rate of celiac disease autoimmunity amongst patients with T1D and AITD in the Chinese population. The study included 178 patients with type 1 diabetes and 119 with AITD where 36 had both T1D and AITD, classified as autoimmune polyglandular syndrome type 3 variant (APS3v). The study also included 145 patients with type 2 diabetes (T2D), 97 patients with non-autoimmune thyroid disease (NAITD), and 102 healthy controls. Serum islet autoantibodies, thyroid autoantibodies and TGA were measured by radioimmunoassay. TGA positivity was found in 22% of patients with either type 1 diabetes or AITD, much higher than that in patients with T2D (3.4%; p< 0.0001) or NAITD (3.1%; P < 0.0001) or healthy controls (1%; p<0.0001). The patients with APS3v having both T1D and AITD were 36% positive for TGA, significantly higher than patients with T1D alone (p = 0.040) or with AITD alone (p = 0.017). T1D and AITD were found to have a 20% and 30% frequency of overlap respectively at diagnosis. In conclusion, TGA positivity was high in the Chinese population having existing T1D and/or AITD, and even higher when both diseases were present. Routine TGA screening in patients with T1D or AITD will be important to early identify celiac disease autoimmunity for better clinical care of patients. PMID:27427767

    Celiac disease (CD) is associated with both lymphoproliferative malignancy (LPM) and increased death from LPM. Research suggests that co-existing autoimmune disease may influence survival in LPM. Through Cox regression we examined overall and cause-specific mortality in 316 individuals with CD+LPM vs. 689 individuals with LPM only. CD was defined as having villous atrophy according to biopsy reports at any of Sweden’s 28 pathology departments, and LPM as having a relevant disease code in the Swedish Cancer Register. During follow-up, there were 551 deaths (CD: n=200; non-CD: n=351). Individuals with CD+LPM were at an increased risk of death compared with LPM-only individuals (adjusted hazard ratio (aHR)=1.23; 95% confidence interval (CI)=1.02–1.48). However, this excess risk was only seen in the first year after LPM diagnosis (aHR=1.76), with HRs decreasing to 1.09 in years 2–5 after LPM diagnosis and to 0.90 thereafter. Individuals with CD and non-Hodgkin lymphoma (NHL) were at a higher risk of any death as compared with NHL-only individuals (aHR=1.23; 95%CI=0.97–1.56). This excess risk was due to a higher proportion of T-cell lymphoma in CD patients. Stratifying for T- and B-cell status, the HR for death in individuals with CD+NHL was 0.77 (95%CI=0.46–1.31 In conclusion, we found no evidence that co-existing CD influences survival in individuals with LPM. The increased mortality in the first year after LPM diagnosis is related to the predominance of T-NHL in CD individuals. Individuals with CD+LPM should be informed that their prognosis is similar to that of individuals with LPM only. However, this study had low statistical power to rule our excess mortality in patients with CD and certain LPM subtypes. PMID:23463575

    In the last years, a potential link between endometriosis and celiac disease has been hypothesized since these disorders share some similarities, specifically concerning a potential role of oxidative stress, inflammation, and immunological dysfunctions. We investigated the prevalence of celiac disease among Italian women with endometriosis with respect to general population. Consecutive women with a laparoscopic and histological confirmed diagnosis of endometriosis were enrolled; female nurses of our institution, without a known history of endometriosis, were enrolled as controls. IgA endomysial and tissue transglutaminase antibodies measurement and serum total IgA dosage were performed in both groups. An upper digestive endoscopy with an intestinal biopsy was performed in case of antibodies positivity. Presence of infertility, miscarriage, coexistence of other autoimmune diseases, and family history of autoimmune diseases was also investigated in all subjects. Celiac disease was diagnosed in 5 of 223 women with endometriosis and in 2 of 246 controls (2.2% versus 0.8%; P = 0.265). Patients with endometriosis showed a largely higher rate of infertility compared to control group (27.4% versus 2.4%; P < 0.001). Our results confirm that also in Italian population an increased prevalence of celiac disease among patients with endometriosis is found, although this trend does not reach the statistical significance.

    Celiac disease is a chronic intestinal disease caused by intolerance to gluten associated with poor digestion and absorption of the majority of nutrients and vitamins, which may affect both developing dentition and oral mucosa. The aim of this study is to make a brief review of the literature about celiac disease and to report on a clinical case, showing the impact it may have on the general and oral health. A 39-year-old woman reported the presence of diarrhea, nauseas, flatulence, colic, difficulty with falling asleep, lack of appetite and loose of 18 Kg in the last two years. She also noted the appearance of symptomatic lesions in the mouth. These lesions had a mean duration of a month and occurred in any region of the oral mucosa, particularly on the tongue. Multiples ulcerations were found in the sublingual caruncula region, at the vestibular fornix and at the lingual apex. Topical treatment was instituted for the oral lesions with immediately relief of the symptoms. The diagnosis of celiac disease was established by means of medical clinical exam, biopsy of the small intestine, and by the presence of specific antibodies in the blood. The patient has been instructed to follow a gluten-free diet. Multiprofessional action with the involvement of a gastroenterologist and other health professionals, such as dentists, is important for diagnosing the disease and guiding the patient with celiac disease to achieve a good quality of life.

    AIM: To explore whether there was anti-Saccharomyces cerevisiae antibodies (ASCA) positivity in our patients with biopsy-confirmed celiac disease. METHODS: A cohort of patients with inflammatory bowel diseases (42 patients with Crohn’s disease and 10 patients with ulcerative colitis) and gluten sensitive enteropathy (16 patients) from Debrecen, Hungary were enrolled in the study. The diagnosis was made using the formally accepted criteria. Perinuclear antineutrophil cytoplasmic antibodies (pANCA) and anti-Saccharomyces cerevisiae antibodies (ASCA), antiendomysium antibodies (EMA), antigliadin antibodies (AGA) and anti human tissue transglutaminase antibodies (tTGA) were investigated. RESULTS: The results showed that ASCA positivity occurred not only in Crohn’s disease but also in Celiac disease and in these cases both the IgG and IgA type antibodies were proved. CONCLUSION: It is conceivable that ASCA positivity correlates with the (auto-) immune inflammation of small intestines and it is a specific marker of Crohn’s disease. PMID:14562398

A slight increase of fracture risk is evident in this condition, particularly in those with overt malabsorption and in postmenopausal state. The adoption of a correct gluten-free diet (GFD) improves bone derangement, but is not able to normalize bone mass in all the patients. Biomarkers effective in the prediction of bone response to gluten-free diet are not yet available and the indications of guidelines are still imperfect and debated.

    Introduction. Celiac disease is associated with an increased risk of small bowel malignancies, particularly lymphoma. Its association with small bowel carcinoma is less known. Case Description. We report a case of an 89-year-old woman with celiac disease who experienced recurrent episodes of gastrointestinal bleeding and was ultimately found to have adenocarcinoma of the small intestine. Discussion and Evaluation. Diagnosis of small bowel adenocarcinoma is often delayed because of the need for specialized modalities, which are often deferred in the inpatient setting. Although resection is the modality of choice for small bowel tumors, a majority is either locally advanced or metastatic at diagnosis, and even localized cancers have worse prognosis than stage-matched colorectal tumors. The role of adjuvant chemotherapy is uncertain, but it is often offered extrapolating data from other gastrointestinal cancers. Small bowel carcinomas occurring in the context of celiac disease appear to be associated with higher rates of microsatellite instability than sporadic tumors, although other specific genomic abnormalities and mechanisms of carcinogenesis in celiac disease remain unknown. Conclusion. Recurrent episodes of gastrointestinal bleeding in a patient with celiac disease should prompt an early evaluation of the small bowel to assure timely diagnosis of carcinoma at an early curable stage.

    Objective The only treatment for celiac disease is lifelong adherence to a gluten-free diet, yet adherence is limited and factors influencing adherence are poorly understood. The purpose of this study was to determine factors influencing gluten-free diet adherence in adults with celiac disease. Methods A questionnaire was developed and administered to 154 adults with celiac disease who then underwent a standardized gluten-free diet evaluation by an experienced nutritionist. Multivariate analysis was conducted to determine factors associated with adherence level. Results Thirteen factors hypothesized to contribute to gluten-free diet adherence were found to be significantly associated with improved adherence including: understanding of the gluten-free diet, membership of a celiac disease advocacy group, and perceived ability to maintain adherence despite travel or changes in mood or stress (P < 0.001). Conclusions This study identified specific factors correlated with gluten-free diet adherence. These results provide a foundation for the design of educational interventions to improve adherence.

We present a case of repigmentation of vitiligo lesions in a girl with celiac disease after initiating a gluten-free diet, which to our knowledge has not been reported. PMID:21504457

    This work aims to estimate celiac disease prevalence in school-children in the island of Djerba and assess rapid method feasibility for screening. We screened 2064 schoolchildren by a rapid method to detect IgA anti-tissue transglutaminase and IgA deficiency. Children with positive results were tested for IgA anti-transglutaminase and anti-endomysium by conventional tests. In positive children, intestinal biopsy was performed. IgA deficiency suspected by rapid method was confirmed by nephelometry. In these cases IgG anti-endomysium was performed. Rapid test was positive in 7 children; conventional serology was positive in all and 6 of them accepted the biopsy. Total villous atrophy was observed in 5 while intestinal mucosa was normal in one. Among children with positive serology, 3 had silent form, 1 chronic diarrhea, one growth failure and 2 had borderline growth. IgA deficiency was suspected in 13 cases and was confirmed in 11 children tested. Prevalence of celiac disease was 0.24-0.34% and that of IgA deficiency 0.5-0.6%. This screening study confirms that celiac disease is relatively common in schoolchildren in Tunisia. It confirms also that even those with symptoms typical for celiac disease escape diagnosis. Rapid test is better accepted by parents and children than test requiring a venous blood sample. PMID:23883201

    Type 1 diabetes mellitus is associated with celiac disease, with a prevalence that varies between 0.6% and 16.4%, according to different studies. After a diagnosis of celiac disease is confirmed by small bowel biopsy, patients are advised to commence a gluten-free diet (GFD). This dietary restriction may be particularly difficult for the child with diabetes, but in Europe (and in Italy) many food stores have targeted this section of the market with better labeling of products and more availability of specific GFD products. Treatment with a GFD in symptomatic patients has been shown to improve the symptoms, signs and complications of celiac disease. However, the effects of a GFD on diabetic control are less well established. Initial reports of improved hypoglycemic control were based on children who were diagnosed with celiac disease associated with malabsorption, but there have subsequently been reports of improvement in patients with type 1 diabetes with subclinical celiac disease. There are other studies reporting no effect, improved control and an improvement of hypoglycemic episodes. Moreover, in this review we wish to focus on low glycemic index foods, often suggested in people with type 1 diabetes, since they might reduce postprandial glycemic excursion and enhance long-term glycemic control. In contrast, GFD may be rich in high glycemic index foods that can increase the risk of obesity, insulin resistance and cardiovascular disease, worsening the metabolic control of the child with diabetes. Hence, it is important to evaluate the impact of a GFD on metabolic control, growth and nutritional status in children with type 1 diabetes. PMID:23961323

    Introduction The role of serological tests such as IgA anti-transglutaminase autoantibodies has become increasingly important in celiac disease (CD) diagnosis. However, the efficiency of these tests for patient follow-up is controversial. We investigated the correlation of 12 different serological tests, including recent deamidated gliadin and actin IgA tests, with villous atrophy (VA) in a retrospective cohort of treated celiac patients. Materials and Methods Serum samples were collected from 100 treated CD patients who had intestinal biopsy in the course of their follow-up. Antibodies against transglutaminase, deamidated gliadin peptides, and native gliadin were measured, along with IgA anti-actin. The biopsy slides were all blind-reviewed and scored according to Marsh classification. Results For all deamidated gliadin and transglutaminase tests, we found that a positive result was significantly associated with persistence of intestinal VA, with a diagnostic efficacy up to 80%. Furthermore, antibodies titers directly correlated with the degree of VA, indicating a strong link between disease activity and presence of antibodies in the serum. Interestingly, the tests with the highest association with persistent VA were those for deamidated gliadin IgG. Using a test positivity pattern analysis, we were also able to identify several groups of patients with distinct antibody profiles that showed significant differences in intestinal damage and diet compliance. Conclusions Altogether, these results show that deamidated gliadin antibodies are strongly correlated with VA and should be considered valuable tools in CD follow-up and that multiplex serologic analysis for treated CD represents a promising tool for personalized patient management.

    Background & Aims There have been inconsistent reports of pre- and perinatal factors that affect risk for development of celiac disease. We assessed the association of fetal growth, birth weight, and mode of delivery with development of celiac disease within the Norwegian Mother and Child (MoBa) cohort study. Methods The MoBa cohort contains pregnancy information on 95,200 women and data on their 114,500 children, collected in Norway from 1999 through 2008; it is linked to the Medical Birth Registry. Women and children with celiac disease were identified from the National Patient Register and from women's responses to MoBa questionnaires. We calculated odds ratios (ORs) for celiac disease using a multivariable logistic regression model, adjusting for maternal celiac disease, sex of children, and children's age (model 1); in a second model, we adjusted for age of gluten introduction and duration of breastfeeding (model 2). Results We identified 650 children with celiac disease and 107,828 controls in the MoBa database. We found no association between birth weight or height with celiac disease (born small for gestational age was not associated). Celiac disease was not associated with mode of delivery (Cesarean section, model 1: OR=0.84; 95% confidence interval [CI], 0.65–1.09 and model 2: OR=0.83; 95% CI, 0.63−1.09). Maternal celiac disease, adjusted for age and sex of the children (OR=12.45; 95% CI, 8.29−18.71) and type 1 diabetes (model I: OR=2.58; 95% CI, 1.19−5.53 and model 2: OR=2.61; 95% CI, 1.14−5.98) were associated with development of celiac disease in children, whereas maternal type 2 diabetes and gestational diabetes were not. Conclusion Based on analysis of the Norwegian MoBa cohort, development of celiac disease in children is significantly associated with sex of the child, maternal celiac disease and type 1 diabetes, but not with intrauterine growth.

    Celiac disease is an autoimmune disease that affects the villi of the small intestine causing abdominal pain, gas, diarrhea, or bad absorption due to gluten intolerance. The only treatment for this disease consists of a lifelong gluten free diet; this is, celiac people cannot consume products containing gluten, such as wheat, barley, and rye, but they can use rice and corn. Thus, rice flour is mainly used for the manufacturing of the basic products of this population. Unfortunately, rice can contain high contents of total (t-As) and inorganic (i-As) arsenic. The current study demonstrated that products for celiac children with a high percentage of rice contained high concentrations of arsenic (256 and 128 μg kg⁻¹). The daily intake of i-As ranged from 0.61 to 0.78 μg kg⁻¹ body weight (bw) in children up to 5 y of age; these values were below the maximum value established by the EFSA Panel (8.0 μg kg⁻¹ bw per day), but it should be considered typical of populations with a high exposure to this pollutant. Finally, legislation is needed to improve the labeling of these special rice-based foods for celiac children; label should include information about percentage, geographical origin, and cultivar of the used rice.

    OBJECTIVE: To test the effectiveness of serologic antigliadin antibody (AGA) testing in predicting celiac disease in children. DESIGN: Prospective clinical assessment. SETTING: Hôpital Sainte-Justine, montreal. PATIENTS: A total of 176 children with possible celiac disease who were referred for duodenal biopsy between January 1992 and June 1995. OUTCOME MEASURES: IgA and IgG AGA titres, as determined by enzyme-linked immunosorbent assay (ELISA); duodenal biopsy; clinical outcome on a gluten-free diet. RESULTS: Of the 176 children 30 were found to have celiac disease according to the criteria of the European Society of Pediatric Gastroenterology and Nutrition (ESPGAN). The sensitivity and specificity of the IgA AGA titre, as well as its positive and negative predictive values, were 80%, 92%, 67% and 96% respectively; the corresponding values for the IgG AGA titre were 83%, 79%, 45% and 96%. The respective values for IgA and IgG AGA titres combined were 93%, 71%, 43% and 98%. Only 2 of the 30 patients with celiac disease had false-negative results for both IgA and IgG AGA titres. The IgA and IgG AGA titres decreased significantly (p < 0.005) in all 11 patients after being on a gluten-free diet for at least 10 months and reached normal values in 8. CONCLUSION: AGA screening for celiac disease permits better selection of patients for duodenal biopsy and adds specificity to the histologic diagnosis. Such screening cannot replace intestinal biopsy, which remains the gold standard for diagnosis. PMID:9294391

  8. The influence of gluten: weaning recommendations for healthy children and children at risk for celiac disease.

    PubMed

    Guandalini, Stefano

    2007-01-01

    In most developed countries, gluten is currently most commonly introduced between 4 and 6 months of age, in spite of little evidence to support this practice. As for infants at risk of developing food allergies, there is clear evidence that introducing solid foods before the end of the 3rd month is detrimental and should be avoided. A recent growing body of evidence however challenges the notion that solids (and among them, gluten-containing foods) should be introduced beyond the 6th month of life. Another important aspect of gluten introduction into the diet has to do with its possible role in causing type-1 diabetes (IDDM). Recently, a large epidemiological investigation in a cohort of children at risk for IDDM found that exposure to cereals (rice, wheat, oats, barley, rye) that occurred early (< or = 3 months) as well as late (> or = 7 months) resulted in a significantly higher risk of the appearance of islet cell autoimmunity compared to the introduction between 4 and 6 months. As for celiac disease, the protective role of breastfeeding can be considered ascertained, especially the protection offered by having gluten introduced while breastfeeding is continued. Evidence is emerging that early (< or = 3 months) and perhaps even late (7 months or after) first exposure to gluten may favor the onset of celiac disease in predisposed individuals. Additionally, large amounts of gluten at weaning are associated with an increased risk of developing celiac disease, as documented in studies from Scandinavian countries. In celiac children observed in our center, we could show that breastfeeding at the time of gluten introduction delays the appearance of celiac disease and makes it less likely that its presentation is predominantly gastrointestinal. Based on current evidence, it appears reasonable to recommend that gluten be introduced in small amounts in the diet between 4 and 6 months, while the infant is breastfed, and that breastfeeding is continued for at least a

    BACKGROUND: Celiac disease can present with mild or nongastrointestinal symptoms, and may escape timely recognition. The treatment of celiac disease involves a gluten-free diet, which is complex and challenging. OBJECTIVE: To evaluate clinical features and symptom recovery on a gluten-free diet in a Canadian adult celiac population. METHODS: All adult members (n=10,693) of the two national celiac support organizations, the Canadian Celiac Association and Fondation québécoise de la maladie coeliaque, were surveyed using a questionnaire. RESULTS: A total of 5912 individuals (≥18 years of age) with biopsy-confirmed celiac disease and/or dermatitis herpetiformis completed the survey. The female to male ratio was 3:1, and mean (± SD) age at diagnosis was 45.2±16.4 years. Mean time to diagnosis after onset of symptoms was 12.0±14.4 years. Abdominal pain and bloating (84.9%), extreme weakness/tiredness (74.2%), diarrhea (71.7%) and anemia (67.8%) were the most commonly reported symptoms at the time of diagnosis. Many respondents continued to experience symptoms after being on a gluten-free diet for >5 years. Sex differences were reported in clinical features before diagnosis, recovery after being on gluten-free diet and perceived quality of life, with women experiencing more difficulties than men. CONCLUSIONS: Delays in diagnosis of celiac disease in Canada remain unacceptably long despite wider availability of serological screening tests. Many patients report continuing symptoms despite adhering to a gluten-free diet for >5 years, with women experiencing more symptoms and a lower recovery rate than men. Awareness of celiac disease needs improvement, and follow-up with a physician and a dietitian is essential for all patients with celiac disease. PMID:23936873

    An electrochemical magneto immunosensor for the detection of anti-transglutaminase antibodies (ATG2) in celiac disease was developed. The immunological reaction is performed on magnetic beads (MBs) as a solid support in which the transglutaminase enzyme (TG2) is covalently immobilized (TG2-MB) and then ATG2 were revealed by an antibody labeled with peroxidase. The electrochemical response of the enzymatic reaction with o-phenilendiamine and H₂O₂ as substrates by square wave voltammetry was correlated with the ATG2. Graphite-epoxi composite cylindrical electrodes and screen printed electrodes were used as transducers in the immunosensor. A total number of 29 sera from clinically confirmed cases of celiac disease and 19 negative control sera were tested by the electrochemical magneto immunosensor. The data were submitted to the receiver-operating characteristic plot (ROC) analysis which indicated that 16.95 units was the most effective cut-off value (COV) to discriminate correctly between celiac and non-celiac patients. Using this point for prediction, sensitivity was found to be 100%, while specificity was 84%. PMID:23685317

    Celiac disease is characterized by intestinal inflammation caused by gluten, proteins which are widely contained in the Western diet. Mammalian digestive enzymes are only partly capable of cleaving gluten, and fragments remain that induce toxic responses in celiac patients. We found that the oral microbiome is a novel and rich source of gluten degrading enzymes. Here we report on the isolation and characterization of the cultivable resident oral microbes that are capable of cleaving gluten, with special emphasis on its immunogenic domains. Bacteria were obtained by a selective culturing approach and enzyme activities were characterised by: 1) Hydrolysis of paranitroanilide-derivatised gliadin-derived tripeptide substrates; 2) Gliadin degradation in-gel (gliadin zymography); 3) Gliadin degradation in solution; 4) Proteolysis of the highly immunogenic α-gliadin-derived 33-mer. For select strains pH activity profiles were determined. The culturing strategy yielded 87 aerobic and 63 anaerobic strains. Species with activity in at least two of the four assays were typed as: Rothia mucilaginosa HOT-681, Rothia aeria HOT-188, Actinomyces odontolyticus HOT-701, Streptococcus mitis HOT-677, Streptococcus sp. HOT-071, Neisseria mucosa HOT-682 and Capnocytophaga sputigena HOT-775, with Rothia species being active in all four assays. Cleavage specificities and substrate preferences differed among the strains identified. The approximate molecular weights of the enzymes were ~75 kD (Rothia spp.), ~60 kD (A. odontolyticus) and ~150 kD (Streptococcus spp.). In conclusion, this study identified new gluten-degrading microorganisms in the upper gastro-intestinal tract. A cocktail of the most active oral bacteria, or their isolated enzymes, may offer promising new treatment modalities for celiac disease. PMID:23714165

    Objective Gastrointestinal symptoms are a common feature in children with autism, drawing attention to a potential association with celiac disease or gluten sensitivity. However, studies to date regarding the immune response to gluten in autism and its association with celiac disease have been inconsistent. The aim of this study was to assess immune reactivity to gluten in pediatric patients diagnosed with autism according to strict criteria and to evaluate the potential link between autism and celiac disease. Methods Study participants included children (with or without gastrointestinal symptoms) diagnosed with autism according to both the Autism Diagnostic Observation Schedule (ADOS) and the Autism Diagnostic Interview, Revised (ADI-R) (n = 37), their unaffected siblings (n = 27), and age-matched healthy controls (n = 76). Serum specimens were tested for antibodies to native gliadin, deamidated gliadin, and transglutaminase 2 (TG2). Affected children were genotyped for celiac disease associated HLA-DQ2 and -DQ8 alleles. Results Children with autism had significantly higher levels of IgG antibody to gliadin compared with unrelated healthy controls (p<0.01). The IgG levels were also higher compared to the unaffected siblings, but did not reach statistical significance. The IgG anti-gliadin antibody response was significantly greater in the autistic children with gastrointestinal symptoms in comparison to those without them (p<0.01). There was no difference in IgA response to gliadin across groups. The levels of celiac disease-specific serologic markers, i.e., antibodies to deamidated gliadin and TG2, did not differ between patients and controls. An association between increased anti-gliadin antibody and presence of HLA-DQ2 and/or -DQ8 was not observed. Conclusions A subset of children with autism displays increased immune reactivity to gluten, the mechanism of which appears to be distinct from that in celiac disease. The increased anti-gliadin antibody

    Given the advances in diagnosis for CD, some patients are detected with symptoms and signs of food intolerance, which have positive antibodies and autoantibodies for coeliac disease, whom present proximal bowel biopsies with chronic nonspecific duodenitis and are not associated with stages 0 and 1 Marsh. On the other hand, patients with bloating, abdominal pain, pondostatural delay, negative antibodies for CD, and chronic nonspecific duodenitis in whom removing cow's milk or gluten, the symptoms remit. There are also celiac patients with biopsies before diagnosis, with chronic nonspecific duodenitis. In this paper, we summarize three brothers with different degrees of chronic duodenitis, one with chronic nonspecific duodenitis, and two with histopathological sings of coeliac disease. It is an invitation to think that chronic nonspecific duodenitis in some patients may be an earlier manifestation of celiac disease. PMID:26544059

    Metabolic bone disease is a frequent co-morbidity in newly diagnosed adults with celiac disease (CD), an autoimmune disorder triggered by the ingestion of dietary gluten. This systematic review of studies looked at the efficacy of the gluten-free diet, physical activity, nutrient supplementation, and bisphosphonates for low bone density treatment. Case control and cohort designs were identified from PubMed and other academic databases (from 1996 to 2015) that observed newly diagnosed adults with CD for at least one year after diet treatment using the dual-energy x-ray absorptiometry (DXA) scan. Only 20 out of 207 studies met the inclusion criteria. Methodological quality was assessed using the Strengthening of the Reporting of Observational Studies in Epidemiology (STROBE) statement checklist. Gluten-free diet adherence resulted in partial recovery of bone density by one year in all studies, and full recovery by the fifth year. No treatment differences were observed between the gluten-free diet alone and diet plus bisphosphonates in one study. For malnourished patients, supplementation with vitamin D and calcium resulted in significant improvement. Evidence for the impact of physical activity on bone density was limited. Therapeutic strategies aimed at modifying lifestyle factors throughout the lifespan should be studied. PMID:25961322

    Abstract Background: Celiac disease (CD) has been linked to cancer, especially lymphoproliferative malignancy (LPM). Earlier research has shown that first-degree relatives (FDRs) to individuals with CD are at increased risk of autoimmunity including CD, but data on their risk of cancer are scarce and contradictory. We aimed to assess whether Swedish FDRs to individuals with CD are at increased risk of cancer. Methods: Individuals with CD (identified through biopsy reports equal to Marsh grade III) were matched on sex, age, county, and calendar year with up to 5 control individuals. All FDRs (father, mother, sibling, offspring) of CD individuals (“celiac FDRs”: n = 109,391) and controls (n = 548,465) were identified through Swedish healthcare registries. Through Cox regression, we calculated hazard ratios (HRs) for cancer incidence (all cancer, breast cancer, gastrointestinal cancer, and LPM). Results: During follow-up, celiac FDRs experienced 10,750 unique cancers as opposed to 54,686 in-control FDRs. Celiac FDRs were at a slightly lower risk of any cancer (HR 0.97, 95% confidence interval [CI] 0.95–0.99), partially due to the lower risk of breast cancer (HR 0.92, 95% CI 0.87–0.98). The relative risks of LPM (HR 0.99, 95% CI 0.91–1.08) and gastrointestinal cancer (HR 0.98, 95%CI 0.93–1.03) were both close to 1. As opposed to earlier research, we found no excess risk of LPM in siblings to individuals with CD (HR 0.98, 95% CI 0.81–1.19). Conclusion: Celiac FDRs are not at increased risk of cancer, including LPM, arguing that shared genetics is unlikely to explain previous reports of an excess risk of LPM in patients with CD.

    Bone mineral density (/sup 125/I photon absorptiometry) was lower in 20 untreated adult celiac patients than in sex- and age-matched controls (p less than 0.001), and plasma alkaline phosphatase, parathyroid hormone, urinary hydroxyproline/creatinine levels were higher than normal (p less than 0.05, less than 0.001, less than 0.05, respectively). Gluten-free diet was started, and the patients were divided randomly into two treatment groups, one which received oral 25-hydroxyvitamin D 50 micrograms/day and one which did not. After 12 months' treatment, bone turnover markers showed a decrease, which did not reach statistical significance, and bone mineral density did not show significant modifications compared with base line in either group. It was found that a gluten-free diet followed for 1 yr can prevent further bone loss, but no significant differences were detected between the two groups.

    Transglutaminases have been implicated in various human diseases. A prominent example is the involvement of transglutaminase 2 (TG2) in the gluten-sensitive enteropathy celiac disease, where the enzyme is both the target of autoantibodies and responsible for the generation of immunogenic gluten epitopes. Here, we aimed to characterize the microenvironment of TG2 in the extracellular matrix (ECM) in order to gain insights into the antigenic structures that are recognized by autoantibodies in celiac disease. A panel of TG2-specific mAbs established from gut plasma cells of celiac disease patients was employed as probes to characterize the interactions between TG2 and ECM constituents. With immunofluorescence staining, microplate protein-binding and surface plasmon resonance assays, we found that the main epitope (epitope 1) recognized by TG2-specific gut plasma cells overlaps with the fibronectin (FN)-binding site of TG2. Furthermore, we found that the same TG2 amino acids that are involved in binding of epitope 1 mAbs are also important for efficient binding of FN. Notably, epitope 1 mAbs recognize TG2 in tissue sections, suggesting that some TG2 in the extracellular matrix has interaction partners in addition to FN. We demonstrate that collagen VI is a strong candidate, on the basis of its tissue expression pattern and ability to bind TG2. Collagen VI may thus serve as a matrix for deposition of TG2 in a context that can also be recognized by epitope 1-targeting autoantibodies. PMID:25808416

    2015-01-01

    Celiac disease (CD) and type 1 diabetes (T1D) are autoimmune conditions in which dietary gluten has been proven or suggested to play a pathogenic role. In CD; gluten is established as the instigator of autoimmunity; the autoimmune process is halted by removing gluten from the diet; which allows for resolution of celiac autoimmune enteropathy and subsequent normalization of serological markers of the disease. However; an analogous causative agent has not yet been identified for T1D. Nevertheless; the role of dietary gluten in development of T1D and the potentially beneficial effect of removing gluten from the diet of patients with T1D are still debated. In this review; we discuss the comorbid occurrence of CD and T1D and explore current evidences for the specific role of gluten in both conditions; specifically focusing on current evidence on the effect of gluten on the immune system and the gut microbiota.

    A 4-year-old boy presented with a history of tremor for 7 days. He also had recurrent diarrhea for the previous 1 year, and poor weight gain. Magnetic resonance of the brain was suggestive of central pontine myelinolysis. There was no evidence of electrolyte abnormalities. The serum tissue transglutaminase level was markedly elevated, and the duodenal biopsy revealed features of celiac disease. The patient was started on gluten-free diet. The tremor resolved within 3 months. Repeat imaging of the brain done 3 months after starting gluten-free diet showed complete resolution of the lesion. This case highlights the unusual presentation of central pontine myelinosis as tremor in a malnourished child with celiac disease. PMID:23390116

    Bilateral non traumatic femoral neck fatigue fracture is a rare condition usually occurring secondary to medical conditions such as pregnancy, pelvic irradiation, corticosteroid exposure, chronic renal failure and osteomalacia. In this report, we present three young female patients with bilateral femoral neck fracture secondary to osteomalacia. The underlying cause of osteomalacia was Celiac disease in all patients. The patients were treated with closed reduction and internal fixation with cannulated lag screws. They were free of pain and full weight bearing was achieved at three months. There were no complications, avascular necrosis and nonunion during the follow up period. In patients with bone pain, non traumatic fractures and muscle weakness, osteomalacia should be kept in mind and proper diagnostic work-up should be performed to identify the underlying cause of osteomalacia such as celiac disease.

    BACKGROUND: The treatment of celiac disease is a strict, life-long gluten-free (GF) diet. This diet is complex and can be challenging. Factors affecting adherence to the GF diet are important to identify for improving adherence. OBJECTIVE: To identify factors that inhibit or improve adherence to a GF diet in children with celiac disease. METHODS: Patients (<18 years of age) with biopsy-confirmed celiac disease followed by the gastroenterology service at a tertiary care paediatric institution were surveyed using a mailed questionnaire. Factors influencing adherence to a GF diet were scored from 1 to 10 based on how often they were problematic (1 = never, 10 = always). Parents of patients <13 years of age were instructed to complete the survey with their child. Adolescents ≥13 years of age were asked to complete the survey themselves. RESULTS: Of 253 subjects, 126 completed the survey; the median age was 12 years (range two to 18 years). Forty percent were adolescents. Overall, participants reported good adherence at home and school, but lower adherence at social events. Adolescents reported lower adherence compared with parents. Availability of GF foods and cost were the most significant barriers. Other factors identified to help with a GF diet included education for schools/restaurants and improved government support. CONCLUSIONS: Availability, cost and product labelling are major barriers to adherence to a GF diet. Better awareness, improved labelling and income support are needed to help patients. PMID:25332660

    While the antigenic specificity and pathogenic relevance of immunologic reactivity to gluten in celiac disease have been extensively researched, the immune response to nongluten proteins of wheat has not been characterized. We aimed to investigate the level and molecular specificity of antibody response to wheat nongluten proteins in celiac disease. Serum samples from patients and controls were screened for IgG and IgA antibody reactivity to a nongluten protein extract from the wheat cultivar Triticum aestivum Butte 86. Antibodies were further analyzed for reactivity to specific nongluten proteins by two-dimensional gel electrophoresis and immunoblotting. Immunoreactive molecules were identified by tandem mass spectrometry. Compared with healthy controls, patients exhibited significantly higher levels of antibody reactivity to nongluten proteins. The main immunoreactive nongluten antibody target proteins were identified as serpins, purinins, α-amylase/protease inhibitors, globulins, and farinins. Assessment of reactivity toward purified recombinant proteins further confirmed the presence of antibody response to specific antigens. The results demonstrate that, in addition to the well-recognized immune reaction to gluten, celiac disease is associated with a robust humoral response directed at a specific subset of the nongluten proteins of wheat.

    AIM: To describe the cardiovascular disease (CVD) risk factors in a population of children with celiac disease (CD) on a gluten-free diet (GFD). METHODS: This cross-sectional multicenter study was performed at Schneider Children’s Medical Center of Israel (Petach Tiqva, Israel), and San Paolo Hospital (Milan, Italy). We enrolled 114 CD children in serologic remission, who were on a GFD for at least one year. At enrollment, anthropometric measurements, blood lipids and glucose were assessed, and compared to values at diagnosis. The homeostasis model assessment-estimated insulin resistance was calculated as a measure of insulin resistance. RESULTS: Three or more concomitant CVD risk factors [body mass index, waist circumference, low density lipoprotein (LDL) cholesterol, triglycerides, blood pressure and insulin resistance] were identified in 14% of CD subjects on a GFD. The most common CVD risk factors were high fasting triglycerides (34.8%), elevated blood pressure (29.4%), and high concentrations of calculated LDL cholesterol (24.1%). On a GFD, four children (3.5%) had insulin resistance. Fasting insulin and HOMA-IR were significantly higher in the Italian cohort compared to the Israeli cohort (P < 0.001). Children on a GFD had an increased prevalence of borderline LDL cholesterol (24%) when compared to values (10%) at diagnosis (P = 0.090). Trends towards increases in overweight (from 8.8% to 11.5%) and obesity (from 5.3% to 8.8%) were seen on a GFD. CONCLUSION: This report of insulin resistance and CVD risk factors in celiac children highlights the importance of CVD screening, and the need for dietary counseling targeting CVD prevention.

    Objective Delayed gastric emptying has been frequently detected in patients with untreated celiac disease. According to several studies, gluten withdrawal showed to be effective in normalizing the gastric emptying rate. The aim of this study was to evaluate the gastric emptying rate of solids in patients with celiac disease before and after a gluten-free diet. Methods Twelve adult patients with celiac disease (age range 20-57 years) and 30 healthy controls (age range 30-54 years) underwent a (13)C-octanoic acid breath test to measure gastric emptying. Half emptying time (t1/2) and lag phase (tlag) were calculated. After at least 12 months of a gluten-free diet, celiac patients underwent a new (13)C-octanoic acid breath test. A symptom score was utilized to detect dyspeptic and malabsorption symptoms in all the patients. Results The gastric motility parameters, t1/2 and tlag, were significantly longer in patients than in controls. On a gluten-free diet, surprisingly, the gastric emptying did not normalize despite an improvement of symptom score. No significant correlation between abnormal gastric emptying and specific symptom patterns, anthropometric parameters or severity of histological damage was found. Conclusions This finding supports the hypothesis that gluten-driven mucosal inflammation might determine motor abnormalities by affecting smooth muscle contractility or impairing gut hormone function. The persistence of these abnormalities on a gluten free diet suggests the presence of a persistent low-grade mucosal inflammation with a permanent perturbation of the neuro-immunomodulatory regulation.

Different studies indicated the possible association between lymphocytic gastritis and both CD and H. pylori infection, although this evidence is not consistently accepted. Also it was shown that an increase in intraepithelial lymphocytes count is associated with both H. pylori infection and celiac disease. Therefore the following questions may raise: how far is this infection actually related to CD?, which are the underlying patho-mechanisms for these associations? what are the clinical implications? what is the management? and what would be the role of gluten free diet in treating these conditions?

    Aim: To assess anti-neuronal antibodies (NA) prevalence and their correlation with neurological disorders and bowel habits in celiac disease (CD) patients. Background: Neurological manifestations are estimated to occur in about 10% of celiac disease patients and NA to central nervous system (CNS) and enteric nervous system (ENS) are found in a significant proportion of them. Little is known about the clinical and immunological features in CD patients with neurological manifestations. Patients and methods: NA to CNS and ENS were investigated in 106 CD patients and in 60 controls with autoimmune disorders by indirect immunofluorescence on rat / primate cerebellar cortex and intestinal (small and large bowel) sections. Results: IgG NA to CNS (titer 1:50 - 1:400) were positive in 23 celiacs (21%), being more frequently detected in those with neurological disorders that in those without neurological dysfunction (49% vs. 8%, P< 0.0001). Of the 26 celiacs (24%) with IgG NA to ENS, 11 out of 12 with an antibody titer > 1:200 had severe constipation. Only one patient with cerebellar ataxia and intestinal sub-occlusion was positive for NA to CNS and ENS. NA to CNS and ENS were found in 7% and 5% of controls, respectively. Conclusion: In CD the positivity of NA to CNS can be regarded as a marker of neurological manifestations. High titer NA to ENS are associated with severe constipation. The demonstration of NA to CNS and ENS suggests an immune-mediated pathogenesis leading to central neural impairment as well as gut dysfunction (hence constipation), respectively. PMID:25926940

    Although many groups have attempted to develop an automated computerized method to detect pathology of the small intestinal mucosa caused by celiac disease, the efforts have thus far failed. This is due in part to the occult presence of the disease. When pathological evidence of celiac disease exists in the small bowel it is visually often patchy and subtle. Due to presence of extraneous substances such as air bubbles and opaque fluids, the use of computerized automation methods have only been partially successful in detecting the hallmarks of the disease in the small intestine-villous atrophy, fissuring, and a mottled appearance. By using a variety of computerized techniques and assigning a weight or vote to each technique, it is possible to improve the detection of abnormal regions which are indicative of celiac disease, and of treatment progress in diagnosed patients. Herein a paradigm is suggested for improving the efficacy of automated methods for measuring celiac disease manifestation in the small intestinal mucosa. The suggestions are applicable to both standard and videocapsule endoscopic imaging, since both methods could potentially benefit from computerized quantitation to improve celiac disease diagnosis.

  10. Intestinal involvement is not sufficient to explain hypertransaminasemia in celiac disease?

    PubMed

    2005-01-01

    Chronic unexplained hypertransaminasemia is an isolated clinical manifestation of celiac disease (CD) and lacks of a clear physiopathological explanation. Since CD and tropical sprue (TS) have similar intestinal functional and histological pattern of injury and that an increased inflammatory response has been reported to occur in patients with irritable bowel syndrome (IBS), liver involvement might be expected to occur either in TS or IBS. However, according to author's prior observations, the frequency of hypertransaminasemia is significantly higher in CD than in TS and IBS-diarrhea predominant patients (IBS-D). Thus, based on current knowledge, intestinal mucosal damage, increased intestinal permeability and/or an active intestinal inflammatory response do not completely explain liver damage in CD. We hypothesize that other factors, unique to CD not present in TS or IBS-D, like gluten toxicity and the presence of tissular transglutaminase (tTG) an auto-antigen with pro-inflammatory and remodeling properties, act in addition to intestinal mucosal injury and account to hypertransaminasemia in CD. Further research focusing on the mechanisms of gluten and tTG hepatic toxicity, and/or the characterization of the expression, secretion and enteral-hepatic transport of certain pro-inflammatory cytokines is needed, to understand the possible links between intestinal and liver disorders seen in CD.

    Background Celiac disease (CD) occurs in approximately 1% of the Western population. It is a lifelong disorder that is associated with impaired quality of life (QOL) and an excessive risk of comorbidity and death. Objectives To review the literature on screening for CD in relation to the current World Health Organization (WHO) criteria for mass screening. Methods We performed a PubMed search to identify indexed papers on CD screening with a publication date from 1900 until 1 June 2014. When we deemed an abstract relevant, we read the corresponding paper in detail. Results CD fulfills several WHO criteria for mass screening (high prevalence, available treatment and difficult clinical detection), but it has not yet been established that treatment of asymptomatic CD may reduce the excessive risk of severe complications, leading to higher QOL nor that it is cost-effective. Conclusions Current evidence is not sufficient to support mass screening for CD, but active case-finding may be appropriate, as we recognize that most patients with CD will still be missed by this strategy. Although proof of benefit is still lacking, screening for CD may be appropriate in high-risk groups. PMID:25922671

    Celiac Disease (CD) is a gluten sensitive enteropathy that remains widely undiagnosed and implementation of massive screening tests is needed to reduce the long term complications associated to untreated CD. The main CD autoantigen, human tissue transglutaminase (TG2), is a challenge for the different expression systems available since its cross-linking activity affects cellular processes. Plant-based transient expression systems can be an alternative for the production of this protein. In this work, a transient expression system for the production of human TG2 in Nicotiana benthamiana leaves was optimized and reactivity of plant-produced TG2 in CD screening test was evaluated. First, a subcellular targeting strategy was tested. Cytosolic, secretory, endoplasmic reticulum (C-terminal SEKDEL fusion) and vacuolar (C-terminal KISIA fusion) TG2 versions were transiently expressed in leaves and recombinant protein yields were measured. ER-TG2 and vac-TG2 levels were 9- to 16-fold higher than their cytosolic and secretory counterparts. As second strategy, TG2 variants were co-expressed with a hydrophobic elastin-like polymer (ELP) construct encoding for 36 repeats of the pentapeptide VPGXG in which the guest residue X were V and F in ratio 8:1. Protein bodies (PB) were induced by the ELP, with a consequent two-fold-increase in accumulation of both ER-TG2 and vac-TG2. Subsequently, ER-TG2 and vac-TG2 were produced and purified using immobilized metal ion affinity chromatography. Plant purified ER-TG2 and vac-TG2 were recognized by three anti-TG2 monoclonal antibodies that bind different epitopes proving that plant-produced antigen has immunochemical characteristics similar to those of human TG2. Lastly, an ELISA was performed with sera of CD patients and healthy controls. Both vac-TG2 and ER-TG2 were positively recognized by IgA of CD patients while they were not recognized by serum from non-celiac controls. These results confirmed the usefulness of plant-produced TG2 to

    Two common chronic childhood diseases-celiac disease (CD) and type 1 diabetes (T1D)-result from complex pathological mechanisms where genetic susceptibility, environmental exposure, alterations in intestinal permeability and immune responses play central roles. In this study, we investigated whether these characteristics were universal for CD independently of T1D association. For this purpose, we studied 36 children with normal small-bowel mucosa and 26 children with active CD, including 12 patients with T1D. In samples from the small-bowel mucosa, we detected the lowest expression of tight junction protein 1 (TJP1) mRNA in CD patients with T1D, indicating an increase in intestinal permeability. Furthermore, these samples displayed the highest expression of forkhead box P3 (FoxP3) mRNA, a marker for regulatory T cells, as compared with other patient groups. At the same time, serum levels of IgA antibodies specific for the CD-related antigens deamidated gliadin and tissue transglutaminase (tTG) were the highest in CD patients with T1D. In contrast, no significant differences were found in IgA or IgG antibodies specific for bovine beta-lactoglobulin or Bifidobacterium adolescentis DSM 20083-derived proteins. There were also no differences in the transamidating activity of serum autoantibodies between patients and control individuals. Our results show that patients with T1D and newly detected CD exhibit severely altered intestinal permeability, strong local immune activation and increased immunoregulatory mechanisms in the small bowel. Further study is required to determine whether these extreme changes in this CD subgroup are due to some specific environmental factors (virus infections), unknown genetic effects or autoimmune reactions to antigenic targets in intracellular tight junctions.

    An association between severe aplastic anemia and other autoimmune diseases is rare and has been described in adults for eosinophilic fasciitis, thymomas, systemic lupus erythematosus, and thyroid disorders. Herein we report a patient with celiac disease who was not strictly following a gluten-free diet and presented with progressive pallor, fever, and weakness of 1 month's duration. On investigation, he had pancytopenia, which on subsequent evaluation revealed aplastic anemia. An association between aplastic anemia and celiac disease has rarely been reported. To the best of author's knowledge, only 1 pediatric case of celiac disease associated with aplastic anemia has been published. This is the second report to suggest such an association in children.

    Recently, it has been suggested that the gene called Parkinson's disease 7 (PARK7) might be an upstream activator of hypoxia-inducible factor (HIF)-1α, which plays a major role in sustaining intestinal barrier integrity. Furthermore, PARK7 has been proposed to participate in the Toll-like receptor (TLR)-dependent regulation of the innate immune system. Our aim was to investigate the involvement of PARK7 in the pathogenesis of coeliac disease (CD). Duodenal biopsy specimens were collected from 19 children with untreated CD, five children with treated CD (maintained on gluten-free diet), and ten children with histologically normal duodenal biopsies. PARK7 mRNA expression and protein level were determined by real-time polymerase chain reaction (PCR) and Western blot, respectively. Localization of PARK7 was visualized by immunofluorescence staining. Protein level of PARK7 increased in the duodenal mucosa of children with untreated CD compared to children with treated CD or to control biopsies (p <0.03). We detected intensive PARK7 staining in the epithelial cells and lamina propria of the duodenal mucosa of children with untreated CD compared with that in control biopsies. Our finding that mucosal expression of PARK7 is increased suggests that PARK7 is involved in the pathogenesis of gastrointestinal diseases, notably CD. Our results suggest that PARK7 may alter processes mediated by HIF-1α and TLR4, which supports a role for PARK7 in the maintenance of epithelial barrier integrity, immune homeostasis, or apoptosis.

    Celiac disease is a common autoimmune disorder characterized by an intestinal inflammation triggered by gluten, a storage protein found in wheat, rye and barley. Similar to other autoimmune diseases such as type 1 diabetes, psoriasis and rheumatoid arthritis, celiac disease is the result of an immune response to self-antigens leading to tissue destruction and production of autoantibodies. Common diseases like celiac disease have a complex pattern of inheritance with inputs from both environmental as well as additive and non-additive genetic factors. In the past few years, Genome Wide Association Studies (GWAS) have been successful in finding genetic risk variants behind many common diseases and traits. To complement and add to the previous findings, we performed a GWAS including 206 trios from 97 nuclear Swedish and Norwegian families affected with celiac disease. By stratifying for HLA-DQ, we identified a new genome-wide significant risk locus covering the DUSP10 gene. To further investigate the associations from the GWAS we performed pathway analyses and two-locus interaction analyses. These analyses showed an over-representation of genes involved in type 2 diabetes and identified a set of candidate mechanisms and genes of which some were selected for mRNA expression analysis using small intestinal biopsies from 98 patients. Several genes were expressed differently in the small intestinal mucosa from patients with celiac autoimmunity compared to intestinal mucosa from control patients. From top-scoring regions we identified susceptibility genes in several categories: 1) polarity and epithelial cell functionality; 2) intestinal smooth muscle; 3) growth and energy homeostasis, including proline and glutamine metabolism; and finally 4) innate and adaptive immune system. These genes and pathways, including specific functions of DUSP10, together reveal a new potential biological mechanism that could influence the genesis of celiac disease, and possibly also other

    Celiac disease (CD) is a multifactorial chronic inflammatory condition that results in injury of the mucosal lining of the small intestine upon ingestion of wheat gluten and related proteins from barley and rye. Although the exact mechanisms leading to CD are not fully understood, the genetic basis of CD has been relatively well characterized. In this review we briefly review the history of discovery, clinical presentation, pathophysiology, and current understanding of the genetics underlying CD risk. Then, we discuss what is known about the current distribution and evolutionary history of genes underlying CD risk in light of other evolutionary models of disease. Specifically, we conclude that the set of loci underlying CD risk did not cohesively evolve as a response to a single past selection event such as the development of agriculture. Rather, deterministic and stochastic evolutionary processes have both contributed to the present distribution of variation in CD risk loci. Selection has shaped some components of this network, but this selection appears to have occurred at different points in the past. Other parts of the CD risk network have likely arisen due to stochastic processes such as genetic drift. PMID:25401984

    Background and study aims: Celiac disease (CD) is a chronic systemic autoimmune disorder affecting genetically predisposed individuals, triggered and maintained by the ingestion of gluten. Triggered and maintained by the ingestion of gluten, celiac disease is a chronic systemic autoimmune disorder affecting genetically predisposed individuals. Persistent related inflammation of the duodenal mucosa causes atrophy architecture detectable on esophagogastroduodenoscopy (EGD) and histopathology. We investigated the association between endoscopic features and histopathological findings (Marsh) for duodenal mucosa in celiac disease patients and propose an endoscopic classification of severity. Patients and methods: Between January 2000 and March 2010, an electronic database containing 34,540 EDGs of patients aged > 14 years was searched for cases of CD. Out of 109 cases, 85 met the inclusion criteria: conventional EGD combined with chromoendoscopy, zoom and biopsy. EGD types 0, I and II corresponds to Marsh grades 0, 1 and 2, respectively, while EGD type III corresponds to Marsh grade 3 and 4. Results: Five patients (5.8 %) were EGD I but not Marsh grade 1; 25 patients (29.4 %) were EGD II, 4 of whom (16 %) were classified as Marsh grade 2; and 55 patients (64.7 %) were EGD III, 51 (92.7 %) of whom were classified as Marsh grades 3 and 4. The Spearman correlation coefficient (r = 0.33) revealed a significant association between the methods (P = 0.002). Conclusions: Changes in the duodenal mucosa detected on EGD were significantly and positively associated with histopathologic findings. The use of chromoendoscopy in addition to conventional EGD enhances changes in the duodenal mucosa and permits diagnosis of CD, even in routine examinations. The proposed endoscopic classification is practical and easily reproducible and provides valuable information regarding disease extension. PMID:27556094

    Antibodies to the autoantigen transglutaminase 2 (TG2) are a hallmark of celiac disease. We have studied the interaction between TG2 and an anti-TG2 antibody (679-14-E06) derived from a single gut IgA plasma cell of a celiac disease patient. The antibody recognizes one of four identified epitopes targeted by antibodies of plasma cells of the disease lesion. The binding interface was identified by small angle x-ray scattering, ab initio and rigid body modeling using the known crystal structure of TG2 and the crystal structure of the antibody Fab fragment, which was solved at 2.4 Å resolution. The result was confirmed by testing binding of the antibody to TG2 mutants by ELISA and surface plasmon resonance. TG2 residues Arg-116 and His-134 were identified to be critical for binding of 679-14-E06 as well as other epitope 1 antibodies. In contrast, antibodies directed toward the two other main epitopes (epitopes 2 and 3) were not affected by these mutations. Molecular dynamics simulations suggest interactions of 679-14-E06 with the N-terminal domain of TG2 via the CDR2 and CDR3 loops of the heavy chain and the CDR2 loop of the light chain. In addition there were contacts of the framework 3 region of the heavy chain with the catalytic domain of TG2. The results provide an explanation for the biased usage of certain heavy and light chain gene segments by epitope 1-specific antibodies in celiac disease. PMID:26160175

    Background and aim Celiac disease (CD) is a lifelong immune-mediated disease with excess mortality. Early diagnosis is important to minimize disease symptoms, complications, and consumption of healthcare resources. Most patients remain undiagnosed. We developed two electronic medical record (EMR)-based algorithms to identify patients at high risk of CD and in need of CD screening. Methods (I) Using natural language processing (NLP), we searched EMRs for 16 free text (and related) terms in 216 CD patients and 280 controls. (II) EMRs were also searched for ICD9 (International Classification of Disease) codes suggesting an increased risk of CD in 202 patients with CD and 524 controls. For each approach, we determined the optimal number of hits to be assigned as CD cases. To assess performance of these algorithms, sensitivity and specificity were calculated. Results Using two hits as the cut-off, the NLP algorithm identified 72.9% of all celiac patients (sensitivity), and ruled out CD in 89.9% of the controls (specificity). In a representative US population of individuals without a prior celiac diagnosis (assuming that 0.6% had undiagnosed CD), this NLP algorithm could identify a group of individuals where 4.2% would have CD (positive predictive value). ICD9 code search using three hits as the cut-off had a sensitivity of 17.1% and a specificity of 88.5% (positive predictive value was 0.9%). Discussion and conclusions This study shows that computerized EMR-based algorithms can help identify patients at high risk of CD. NLP-based techniques demonstrate higher sensitivity and positive predictive values than algorithms based on ICD9 code searches. PMID:23956016

    Antibodies to the autoantigen transglutaminase 2 (TG2) are a hallmark of celiac disease. We have studied the interaction between TG2 and an anti-TG2 antibody (679-14-E06) derived from a single gut IgA plasma cell of a celiac disease patient. The antibody recognizes one of four identified epitopes targeted by antibodies of plasma cells of the disease lesion. The binding interface was identified by small angle x-ray scattering, ab initio and rigid body modeling using the known crystal structure of TG2 and the crystal structure of the antibody Fab fragment, which was solved at 2.4 Å resolution. The result was confirmed by testing binding of the antibody to TG2 mutants by ELISA and surface plasmon resonance. TG2 residues Arg-116 and His-134 were identified to be critical for binding of 679-14-E06 as well as other epitope 1 antibodies. In contrast, antibodies directed toward the two other main epitopes (epitopes 2 and 3) were not affected by these mutations. Molecular dynamics simulations suggest interactions of 679-14-E06 with the N-terminal domain of TG2 via the CDR2 and CDR3 loops of the heavy chain and the CDR2 loop of the light chain. In addition there were contacts of the framework 3 region of the heavy chain with the catalytic domain of TG2. The results provide an explanation for the biased usage of certain heavy and light chain gene segments by epitope 1-specific antibodies in celiac disease. PMID:26160175

    AIM: To investigate the prevalence of human leukocyte antigen (HLA) DQ2/8 alleles in Southern Italians with liver and gastrointestinal (GI) diseases outside of celiac disease. METHODS: HLA DQ2/8 status was assessed in 443 patients from three ambulatory gastroenterology clinics in Southern Italy (University of Federico II, Naples, Loreto Crispi Hospital, Ruggi D’Aragona Hospital, Salerno). Patients were grouped based on disease status [pre-post transplant liver disease, esophageal/gastric organic and functional diseases, irritable bowel syndrome (IBS) and inflammatory bowel disease (IBD)] and DQ2/8 alleles, which correspond to a celiac disease genetic risk gradient. Subject allele frequencies were compared to healthy Italian controls. RESULTS: One hundred and ninety-six out of four hundred and forty-three (44.2%) subjects, median age 56 years and 42.6% female, were DQ2/8 positive. When stratifying by disease we found that 86/188 (45.7%) patients with liver disease were HLA DQ2/8 positive, 39/73 (53.4%) with functional upper GI diseases and 19/41 (46.3%) with organic upper GI diseases were positive. Furthermore, 38/105 (36.2%) patients with IBS and 14/36 (38.9%) with IBD were HLA DQ2/8 positive (P = 0.21). Compared to healthy controls those with functional upper GI diseases disorders had a 1.8 times higher odds of DQ2/8 positivity. Those with liver disease had 1.3 times the odds, albeit not statistically significant, of DQ2/8 positivity. Both those with IBS and IBD had a lower odds of DQ2/8 positivity compared to healthy controls. CONCLUSION: The proportion of individuals HLA DQ2/8 positive is higher in those with liver/upper functional GI disease and lower in IBS/IBD as compared to general population estimates. PMID:23674852

    Gluten free food for people with celiac disease based on quinoa, rice and corn flours and starches, were formulated. An informatic tool (ALIM V 1.0) developed by the authors, was used for the formulation of these foods. The obtained products were pancakes, scons, precooked pizza and bread which were analyzed in their chemical composition (protein, fat, fiber, moisture, ash and carbohydrates). Water activity (aw), acceptability and texture parameters (hardness, gumminess, chewiness, adhesiveness and cohesiveness) were also determined. Commercial products (C) were taken as reference and were performed the same analysis to formulated products (F). Significant differences were found in protein, fat moisture, ash and fiber content and in most of the texture parameters studied in both food groups (p<0.05). In pancakes and scones (F) was observed an increase of protein of 88 and 198% respectively, while prepizza and bread (F) showed lower contents (8 and 22%) respect to their commercial pairs, however all products (F) have Chemical Scores higher to 100. The aw of products (F) and (C), gave values similar to the data cited on bibliography for analogous products. The formulations more acceptable (values over 80%) were scones and pancakes. Overall, the formulated products provide good quality proteins, have good textural characteristics and adequate percentages of acceptability to be used in the feeding of celiac patients.

    We explore the social process of celiac disease diagnosis using fieldwork in the United States with two celiac support groups, interviews, and a virtual ethnography of an online discussion board. Distinguishing between medical diagnosis, self-diagnosis, and scientific self-diagnosis, we examine patients' varied paths to diagnosis and their attempts to legitimize symptoms as celiac disease. Web-based direct-access testing (DAT) permits patients to bypass physician requisition for testing in their diagnostic quest. While such laboratories do not diagnose disease per se, they provide the consumer with the scientific information necessary to self-diagnose. This scientific self-diagnosis grants individuals greater legitimacy for their claims of an illness identity than self-diagnosis alone, but less legitimacy than medical diagnosis. We examine the implications of scientific self-diagnosis for the social construction of diagnosis and professional and lay ways of knowing. PMID:19559513

    Gluten proteins, namely gliadins, are the primary trigger of the abnormal immune response in celiac disease. It has been hypothesised that modern wheat breeding practices may have contributed to the increase in celiac disease prevalence during the latter half of the 20th century. Our results do not support this hypothesis as Triticum aestivum spp. vulgare landraces, which were not subjected to breeding practices, presented higher amounts of potential celiac disease's immunostimulatory epitopes when compared to modern varieties. Furthermore, high variation between wheat varieties concerning the toxic epitopes amount was observed. We carried out quantitative analysis of gliadin types by RP-HPLC to verify its correlation with the amount of toxic epitopes: ω-type gliadins content explain about 40% of the variation of toxic epitopes in tetraploid wheat varieties. This research provides new insights regarding wheat toxicity and into the controversial idea that human practices may have conducted to an increased exposure to toxic epitopes. PMID:27451149

    Some genetic loci may affect susceptibility to multiple immune system-related diseases. In the current study, we investigated whether the known susceptibility loci for celiac disease (CelD) also associate with Crohn's disease (CD) and/or ulcerative colitis (UC), the two main forms of inflammatory bowel disease (IBD), in Finnish patients. A total of 45 genetic markers were genotyped in a Finnish data set comprising 699 IBD patients and 2482 controls. Single-marker association with IBD and its subphenotypes was tested. A meta-analysis with a Swedish UC data set was also performed. A total of 12 single-nucleotide polymorphisms associated with CD and/or UC (P<0.05). In the subphenotype analysis, rs6974491-ELMO1 (P=0.0002, odds ratio (OR): 2.20) and rs2298428-UBE2L3 (P=5.44 × 10(-5), OR: 2.59) associated with pediatric UC and CD, respectively. In the meta-analysis, rs4819388-ICOSLG (P=0.00042, OR: 0.79) associated with UC. In the subphenotype meta-analysis, rs1738074-TAGAP (P=7.40 × 10(-5), OR: 0.61), rs6974491-ELMO1 (P=0.00052, OR: 1.73) and rs4819388-ICOSLG (P=0.00019, OR: 0.75) associated with familial UC, pediatric UC and sporadic UC, respectively. Multiple CelD risk loci also confer susceptibility for CD and/or UC in the Finnish and Swedish populations. Certain genetic risk variants may furthermore predispose an individual for developing a particular disease phenotype. PMID:22592522

    Celiac disease (CD) is one of the most common causes of malabsorption. It is an immune-mediated disease manifested by diarrhea, steatorrhea, flatulence, and weight loss, caused by ingestion of gluten containing diets. The disease has typical small intestinal biopsy features of villous atrophy, crypt hyperplasia, and intense inflammation of the mucosal layer. The disease is rarely associated with Crohn's disease (CRD). Studies on the impact of CD on the natural history of inflammatory bowel disease (IBD) have shown that the natural course of CRD is not influenced by coexistent CD. We report a case of 54-year female who presented with diarrhea and weight loss. On initial evaluation, CD was diagnosed, and responded to gluten-free diet (GFD). Later on, she developed joint pains and her diarrhea recurred. Further evaluation revealed coexistence of CRD. The treatment of CRD was also initiated and this led to marked improvement in the symptoms of the patient. PMID:27353997

    Introduction An imbalance between excitatory and inhibitory synaptic excitability was observed in de novo patients with celiac disease (CD) in a previous study with Transcranial Magnetic Stimulation (TMS), suggesting a subclinical involvement of GABAergic and glutamatergic neurotransmission in asymptomatic patients. The aim of this investigation was to monitor the eventual changes in the same cohort of patients, evaluated after a period of gluten-free diet. Methods Patients were re-evaluated after a median period of 16 months during which an adequate gluten-free diet was maintained. Clinical, cognitive and neuropsychiatric assessment was repeated, as well as cortical excitability by means of single- and paired-pulse TMS from the first dorsal interosseous muscle of the dominant hand. Results Compared to baseline, patients showed a significant decrease of the median resting motor threshold (from 35% to 33%, p<0.01). The other single-pulse (cortical silent period, motor evoked potentials latency and amplitude, central motor conduction time) and paired-pulse TMS measures (intracortical inhibition and intracortical facilitation) did not change significantly after the follow-up period. Antibodies were still present in 7 subjects. Discussion In patients under a gluten-free diet, a global increase of cortical excitability was observed, suggesting a glutamate-mediated functional reorganization compensating for disease progression. We hypothesize that glutamate receptor activation, probably triggered by CD-related immune system dysregulation, might result in a long-lasting motor cortex hyperexcitability with increased excitatory post-synaptic potentials, probably related to phenomena of long-term plasticity. The impact of the gluten-free diet on subclinical neurological abnormalities needs to be further explored. PMID:26053324

    Objective: To see the various clinical presentations and biochemical profile in adult celiac disease patients of Hyderabad Sindh. Methods: A total 60 suspected cases of adult celiac disease, both males and females were screened out from Liaquat University of Medical and Health Sciences hospital and private clinics at Sadar Hyderabad Sind by non probability purposive sampling during a period from July 2011 to December 2012.Age ranged between 18 to 55 Years. A detailed history and clinical examination was done. Patients already on gluten free diet, age <12years, tuberculosis or cancer of intestine/colon and patients of diabetes and thyroid disorder were excluded, while patients having positive ant tTG (value >15 iu/ml detected by ELISA) were included. The biochemical profile including serum albumin, calcium ,ferritin, SGPT, Alkaline phosphatase and Haemoglobin were estimated in central Diagnostic laboratory LUMHS by taking 10 cc centrifuged blood sample. The data was plotted on SPSS 16, mean and percentages were calculated. Results: All patients were divided in to three groups according to age. The most common group was 18-30 years; (mean, 23.5±5.6) comprised 56.6%. The commonest clinical presentation was diarrhoea in 50%, menstrual irregularity in 21%, walking problems 21%, undue fatigue in 15% and edema in 15%. P values calculated in quantitative variable of males and females. The p value was significant in between serum calcium (p 0.004), haemoglobin (p 0,004), serum ferritin (<0.005) and alkaline phosphatise (<0.005). Conclusion: This study showed that Adult celiac disease was present with entirely different clinical and biochemical profile in patients in this region. PMID:24772128

    AIM: To investigate all patients referred to our center with non-responsive celiac disease (NRCD), to establish a cause for their continued symptoms. METHODS: We assessed all patients referred to our center with non-responsive celiac disease over an 18-mo period. These individuals were investigated to establish the eitiology of their continued symptoms. The patients were first seen in clinic where a thorough history and examination were performed with routine blood work including tissue transglutaminase antibody measurement. They were also referred to a specialist gastroenterology dietician to try to identift any lapses in the diet and sources of hidden gluten ingestion. A repeat small intestinal biopsy was also performed and compared to biopsies from the referring hospital where possible. Colonoscopy, lactulose hydrogen breath testing, pancreolauryl testing and computed tomography scan of the abdomen were undertaken if the symptoms persisted. Their clinical progress was followed over a minimum of 2 years. RESULTS: One hundred and twelve consecutive patients were referred with NRCD. Twelve were found not to have celiac disease (CD). Of the remaining 100 patients, 45% were not adequately adhering to a strict gluten-free diet, with 24 (53%) found to be inadvertently ingesting gluten, and 21 (47%) admitting non-compliance. Microscopic colitis was diagnosed in 12% and small bowel bacterial overgrowth in 9%. Refractory CD was diagnosed in 9%. Three of these were diagnosed with intestinal lymphoma. After 2 years, 78 patients remained well, eight had continuing symptoms, and four had died. CONCLUSION: In individuals with NRCD, a remediable cause can be found in 90%: with continued gluten ingestion as the leading cause. We propose an algorithm for investigation. PMID:22493548

    Abstract Objective To provide clinicians with an update on the diagnosis of celiac disease (CD) and to make recommendations on the indications to screen for CD in patients presenting with low bone mineral density (BMD) or fragility fractures. Quality of evidence A multidisciplinary task force developed clinically relevant questions related to the diagnosis of CD as the basis for a literature search of the MEDLINE, EMBASE, and CENTRAL databases (January 2000 to January 2009) using the key words celiac disease, osteoporosis, osteopenia, low bone mass, and fracture. The existing literature consists of level I and II studies. Main message The estimated prevalence of asymptomatic CD is 2% to 3% in individuals with low BMD. Routine screening for CD is not justified in patients with low BMD. However, targeted screening for CD is recommended for patients who have T-scores of −1.0 or less at the spine or hip, or a history of fragility fractures in association with any CD-related symptoms or conditions; family history of CD; or low urinary calcium levels, vitamin D insufficiency, and raised parathyroid hormone levels despite adequate intake of calcium and vitamin D. Celiac disease testing should be performed while the subject is consuming a gluten-containing diet; initial screening should be performed with human recombinant immunoglobulin (Ig) A tissue transglutaminase or other IgA tissue transglutaminase assays, in association with IgA endomysial antibody immunofluorescence. Duodenal biopsy is necessary to confirm the diagnosis of CD. Human leukocyte antigen typing might assist in confirming or ruling out the diagnosis of CD in cases where serology and histology are discordant. Definitive diagnosis is based on clinical, serologic, and histologic features, combined with a positive response to a gluten-free diet. Conclusion Current evidence does not support routine screening for CD in all patients with low BMD. A targeted case-finding approach is appropriate for patients

    There is no awareness about celiac disease (CD) in Mexico. A 2.9 year old mestizo boy was admitted to a Mexican hospital with muscle cramps and fine tremors. He suffered chronic diarrhea, abdominal distention, hypotrophic limbs, stunting and wasting, and presented hypocalcemia, anemia and high titers of serological markers. Diagnosis of CD was confirmed by a duodenal biopsy. After replacement of calcium and a gluten-free diet, the symptoms resolved within 6 weeks. After 2-months, serum analyses, anthropometric data as well as antibodies titers were normal after 4 years. CD screening tests are needed in chronic diarrhea for any ethnicity patients.

    Patients with celiac disease (CD) have low bone mineral density. Evidence of increased fracture risk in these patients is conflicting, and the indication for bone mineral density screening of all adult CD patients is debated. Our aim was to review current published data on fractures in CD. Cross-sectional cohort studies and one case study were identified by searching Medline and Embase. Although the identified studies are heterogeneous and difficult to compare, the overall findings indicate a positive association between CD and risk of fracture. Adult patients with CD should be considered for bone densitometry in order to estimate fracture risk. PMID:24691647

    OBJECTIVES: Life-long, strict gluten-free diet (GFD) is the only treatment for celiac disease (CD). Because there is still uncertainty regarding the safety of oats for CD patients, the aim was to investigate whether dietary oats influence the immune status of their intestinal mucosa. METHODS: Paired small intestinal biopsies, before and after >11 months on a GFD, were collected from children with CD who were enrolled in a randomized, double-blind intervention trial to either of two diets: standard GFD (GFD-std; n=13) and noncontaminated oat-containing GFD (GFD-oats; n=15). Expression levels of mRNAs for 22 different immune effector molecules and tight junction proteins were determined by quantitative reverse transcriptase (RT)-PCR. RESULTS: The number of mRNAs that remained elevated was higher in the GFD-oats group (P=0.05). In particular, mRNAs for the regulatory T cell (Treg) signature molecules interleukin-10 (IL-10) and transforming growth factor-β1 (TGF-β1), the cytotoxicity-activating natural killer (NK) receptors KLRC2/NKG2C and KLRC3/NKG2E, and the tight junction protein claudin-4 remained elevated. Between the two groups, most significant differences were seen for claudin-4 (P=0.003) and KLRC3/NKG2E (P=0.04). CONCLUSIONS: A substantial fraction of pediatric CD patients seem to not tolerate oats. In these patients, dietary oats influence the immune status of the intestinal mucosa with an mRNA profile suggesting presence of activated cytotoxic lymphocytes and Tregs and a stressed epithelium with affected tight junctions. Assessment of changes in levels of mRNA for claudin-4 and KLC3/NKG2E from onset to after a year on oats containing GFD shows promise to identify these CD patients. PMID:24964993

     Autoimmune polyglandular syndrome (APS) is a combination of different autoimmune diseases. The close relationship between immune-mediated disorders makes it mandatory to perform serological screening periodically in order to avoid delayed diagnosis of additional autoimmune diseases. We studied a patient with type 1 diabetes (T1D) who later developed an autoimmune thyroid disease (ATD) and was referred to our hospital with a serious condition of his clinical status. The patient was suffering from an advance stage of celiac disease (CD), the delay in its diagnosis and in the establishment of a gluten-free dietled the patient to a severe proteincalorie malnutrition. Later, the patient developed an autoimmune hepatitis (AIH). We consider that clinical deterioration in patients with APS should alert physicians about the possible presence of other immune-mediated diseases. Periodic screening for autoantibodies would help to prevent delayed diagnosis and would improve patient's quality of life. PMID:27236159

    Autoimmune disorders are known to be more frequent in women and often associated each others, but it is rare to see multiple autoimmune diseases in a single patient. Recently, the concept of multiple autoimmune syndrome has been introduced to describe patients with at least three autoimmune diseases. We describe a case of a young man with a clinical history of psychiatric symptoms and celiac disease (CD) who was diagnosed to have other two autoimmune disorders: systemic lupus erythematosus (SLE) and Hashimoto's thyroiditis. This case is unusual upon different patterns: the rare combination of the three autoimmune diseases, their appearance in a man and the atypical onset of the diseases with psychiatric symptoms likely to be related either to CD or to SLE.

    Background/Aim: The aim of this study was to investigate the effects of celiac disease on cardiac functions using tissue Doppler echocardiography (TDE). Patients and Methods: The study included 30 patients with celiac disease (CD) and 30 healthy volunteers. Echocardiographic examinations were assessed by conventional echocardiography and tissue Doppler imaging. The peak systolic velocity (S'm), early diastolic myocardial peak velocity (E'm), late diastolic myocardial peak velocity (A'm), E'm/A'm ratio, myocardial precontraction time (PCT'm), myocardial contraction time (CT'm), and myocardial isovolumetric relaxation time (IVRT'm), E to E'm ratio were measured. Results: In pulsed wave Doppler echocardiography, mitral late diastolic flow (A) velocity and E to E'm ratio were significantly higher (P = 0.02 and P = 0,017), E/A ratio was significantly lower (P = 0.008) and IVRT was significantly prolonged (P = 0.014) in patients with CD. In TDE, S'm, E'm, and E'm/A'm ratio were significantly lower, IVRT'm was longer (P = 0.009) from septal mitral annulus and S'm, E'm, E'm/A'm ratio were significantly lower, PCT'm, PCT/ET ratio, IVRT'm were longer, and MPI was higher from lateral mitral annulus in celiac group than controls. Conclusion: Our study confirms that patients with CD have impaired diastolic function. More importantly, we also demonstrated an impairment of myocardial systolic function in patients with CD by TDE. We recommend using TDE in addition to conventional echocardiography parameters for the cardiovascular risk assessment of patients with CD. PMID:26997217

    Enamel defects in permanent and deciduous teeth may be oral manifestations of celiac disease. Sometimes they are the only sign that points to this underdiagnosed autoimmune pathology. However, the etiology of these specific enamel defects remains unknown. Based on previously reported cross-reactivity of antibodies to gliadin with the enamel proteins, amelogenin and ameloblastin, we analyzed (using immunohistochemistry) the ability of anti-gliadin IgG, produced during untreated disease, to recognize enamel organ structures. We used swine germ teeth as a tissue model because they are highly homologous to human teeth in terms of proteins and development biology. Strong staining of the enamel matrix and of the layer of ameloblasts was observed with serum samples from women with celiac disease; high IgG reactivity was found against both gliadin peptides and enamel matrix protein extract, but there was no IgG reactivity against tissue antigens. In line with these findings, the gamma globulin fraction from gliadin-immunized BALB/c mice showed a similar staining pattern to that of amelogenin-specific staining. These results strongly suggest a pathological role for antibodies to gliadin in enamel defect dentition for both deciduous and permanent teeth, considering that IgG can be transported through the placenta during fetal tooth development.

    In the past coeliac disease, or intolerance to gluten, has been considered a rare disease in infancy, whose most important signs were chronic diarrhea with malabsorption and reduced growth. However, besides this classical form, there are a number of other clinical and subclinical forms which may appear even in the adult life and without any overt intestinal sign. The alterations may affect, e.g., the liver, thyroid, skin and the female and male reproductive system. The overall prevalence of the different forms of coeliac disease in Western Europe is at least 1:300. The aim of the present paper is to describe and evaluate the effects of coeliac disease on female reproduction. Such effects include delayed menarche, amenorrhea, infertility and early menopause. Epidemiological studies show that besides reduced fertility, affected women are at higher risk of reproductive problems such as pregnancy loss, low birthweight of offspring and reduced duration of breastfeeding. There are no adequate studies to evidentiate a possible increase of birth defects; nevertheless, coeliac disease induces malabsorption, with deficiencies of nutritional factors essential to prenatal development such as iron, folic acid and vitamin K. The mechanisms underlying the reproductive alterations are still awaiting clarification; however, an interaction among specific nutritional deficiencies, endocrine imbalances and immune disturbances is suspected. As for the other effects associated to the coeliac disease, the possible prevention or treatment of the reproductive effects is only the lifelong maintenance of a gluten-free diet. PMID:11048475

    Gluten are proline- and glutamine-rich proteins present in wheat, barley, and rye and contain the immunogenic sequences that drive celiac disease (CD). Rothia mucilaginosa, an oral microbial colonizer, can cleave these gluten epitopes. The aim was to isolate and identify the enzymes and evaluate their potential as novel enzyme therapeutics for CD. The membrane-associated R. mucilaginosa proteins were extracted and separated by DEAE chromatography. Enzyme activities were monitored with paranitroanilide-derivatized and fluorescence resonance energy transfer (FRET) peptide substrates, and by gliadin zymography. Epitope elimination was determined in R5 and G12 ELISAs. The gliadin-degrading Rothia enzymes were identified by LC-ESI-MS/MS as hypothetical proteins ROTMU0001_0241 (C6R5V9_9MICC), ROTMU0001_0243 (C6R5W1_9MICC), and ROTMU0001_240 (C6R5V8_9MICC). A search with the Basic Local Alignment Search Tool revealed that these are subtilisin-like serine proteases belonging to the peptidase S8 family. Alignment of the major Rothia subtilisins indicated that all contain the catalytic triad with Asp (D), His (H), and Ser (S) in the D-H-S order. They cleaved succinyl-Ala-Ala-Pro-Phe-paranitroanilide, a substrate for subtilisin with Pro in the P2 position, as in Tyr-Pro-Gln and Leu-Pro-Tyr in gluten, which are also cleaved. Consistently, FRET substrates of gliadin immunogenic epitopes comprising Xaa-Pro-Xaa motives were rapidly hydrolyzed. The Rothia subtilisins and two subtilisins from Bacillus licheniformis, subtilisin A and the food-grade Nattokinase, efficiently degraded the immunogenic gliadin-derived 33-mer peptide and the immunodominant epitopes recognized by the R5 and G12 antibodies. This study identified Rothia and food-grade Bacillus subtilisins as promising new candidates for enzyme therapeutics in CD. PMID:27469368

    Over recent years we have seen rising many clinical and scientific innovations about celiac disease (CE), however the most important innovation that will contribute to change the future of the research and clinic in this field is the natural history of the disease. For many years it has been though that a genetic predisposition and the exposure to gluten were necessary and sufficient to develop CE. Recent studies, however, suggest that the loss of tolerance to gluten may occur in any moment of life upon certain conditions. Furthermore, several environmental factors known to play a role in shaping the intestinal microflora have also been considered related to the development of CE. Delivery mode, the infant diet and the use of antibiotics are included among these factors. To this day no large scale studies have determined if and how the microbiome composition and its metabolomic profile may influence the loss of tolerance to gluten and the consequent development of CE. In this paper we describe a prospective, multi-centric and longitudinal study on infants at risk for CE that will use different techniques to better understand the role of the microbome during the first steps in the development of the autoimmune disease.

    Background Individuals with celiac disease (CD) are at increased risk of sepsis. The aim of this study was to examine whether CD influences survival in sepsis of bacterial origin. Methods Nationwide longitudinal registry-based study. Through data on small intestinal biopsies from Sweden’s 28 pathology departments, we identified 29,096 individuals with CD (villous atrophy, Marsh stage III). Each individual with CD was matched with five population-based controls. Among these, 5,470 had a record of sepsis according to the Swedish Patient Register (1,432 celiac individuals and 4,038 controls). Finally we retrieved data on mortality in sepsis patients through the Swedish Cause of Death Registry. Results CD was associated with a 19% increase in overall mortality after sepsis (95% confidence interval (CI) = 1.09–1.29), with the highest relative risk occurring in children (adjusted hazard ratio (aHR) = 1.62; 95%CI = 0.67–3.91). However, aHR for death from sepsis was lower (aHR = 1.10) and failed to reach statistical significance (95%CI = 0.72–1.69). CD did not influence survival within 28 days after sepsis (aHR = 0.98; 95%CI = 0.80–1.19). Conclusions Although individuals with CD seem to be at an increased risk of overall death after sepsis, that excess risk does not differ from the general excess mortality previously seen in celiac patients in Sweden. CD as such does not seem to influence short-term or sepsis-specific survival in individuals with sepsis and therefore is not an independent risk factor for poor prognosis in sepsis. PMID:27124735

    Introduction: The prevalence of autoimmune thyroid disease (AITD) is 10–12% in the general population worldwide. Among various disorders co-existing with AITD, the concomitance of celiac disease (CD) with AITD results in poor absorption of thyroid medications and results in higher doses of the same. Institution of gluten-free diet (GFD) in this cohort helps reduce medication doses. Aim: To screen patients with AITD for the presence of celiac autoimmunity (CA). Materials and Methods: A total of 280 consecutive patients with AITD attending the thyroid Out-patient Department of a tertiary care hospital were screened for the presence of tissue transglutaminase antibodies (immunoglobulin A tissue transglutaminase). Those with a positive titer (but < 10 times the upper limit of normal) underwent upper gastrointestinal endoscopy and duodenal mucosal biopsy for the diagnosis of CD, followed by institution of GFD in confirmed cases. Results: Of a total of 280 (182 females and 98 males) patients with AITD screened, 24 (8.6%) turned out to be positive for CA. Of 24 (8.6%), 15 (8.24%) females and 9 (9.18%) males were positive for CA. There was no statistically significant difference in the thyroxine doses required for normalization of thyroid function and the weight of the patients in CA positive and CA negative patients. Conclusions: The prevalence of CD in patients with AITD is much greater than in the general population. This forms the basis for screening patients with AITD for presence of CD. PMID:26904476

    Food intolerance is becoming increasingly prevalent, and increasing numbers of athletes have celiac disease. This poses challenges as dietary recommendations for exercise are largely based on gluten-containing carbohydrate-rich foods. The K4 cycle race covers 384 km around the Coromandel Peninsula, New Zealand. Lack of sleep, darkness, and temperature variations pose a number of nutritional challenges. Limited food choices present those with celiac disease with even greater challenges. This case study describes the intakes of one such athlete during training and competing in the K4. Nutritional intakes were obtained during training using weighed-food records and during the race via dietary recall and the weighing of foods pre- and post-race. As simple substitution of gluten-containing foods for gluten-free foods leads to increased energy intake, alternatives need to be considered. During the race, insufficient energy was consumed to meet the nutritional guidelines for endurance performance. This was probably due to the nature of the course, racing conditions, the consistency of gluten-free food, and, toward the end of the race, sensory-specific satiety. PMID:22645170

    Summary Background Previous studies yielded conflicting results regarding the presence of an association between celiac disease (CD) and psychiatric disorders including depression. This association has not been studied in the United States. Aim To determine the prevalence of psychiatric and autoimmune disorders in patients with CD in the US compared to control groups. Methods In a case control study, the prevalence of psychiatric and autoimmune disorders was compared in 600 CD patients, 200 irritable bowel syndrome (IBS) patients and 200 healthy controls. Results The prevalence of depression in CD was 17.2% and was similar to that in IBS (18.5%, P = 0.74) and controls (16.0%, P = 0.79). Among CD patients, type I DM was identified as a significant risk factor for depression (P < 0.01) with 37% of patients with both CD and type I DM having clinical depression. Conclusion The prevalence of depression in CD is similar to that in other chronic gastrointestinal diseases and healthy controls. However, there is a markedly elevated risk of depression in patients with both type I DM and CD. Differing rates of type 1 DM among celiac populations may account for disparity in published rates of depression in patients with CD. PMID:19183153

    In our study, we aimed to investigate ischemia modified albumin (IMA) as an oxidative stress marker, as well as other oxidant and antioxidant markers that have not been evaluated in children with celiac disease. A total of 37 pediatric patients who were diagnosed with celiac disease (CD) and 29 healthy children were enrolled in this prospective study. We evaluated the IMA, total oxidant status, total antioxidant capacity, sulfhydryl, and advanced oxidation protein products in all of the subjects. We also compared the levels at the time of the diagnosis, and following a gluten-free diet (GFD) in the children with CD. While the IMA and the other oxidant marker levels were significantly higher in the patient group compared to the control group, the antioxidant marker levels were found to be significantly lower in the patient group, compared to the control group. We also determined that the tissue transglutaminase IgA showed a highly positive correlation, and that the IMA showed a moderately positive correlation with the Marsh-Oberhuber histopathological stage. Additionally, the IMA and other oxidant marker levels were significantly lower, while the antioxidant marker levels were significantly higher after the GFD, compared to the pre-diet period. We detected that oxidative stress played a role in the pathogenesis of CD, and that this could be evaluated using oxidative stress markers, which would regress after the GFD. We also detected that IMA is a marker that shows a correlation with the histopathological stage, and may be used in the diagnosis. PMID:27411418

    Background Celiac disease (CD) is an immune-mediated enteropathy triggered by the ingestion of gluten in susceptible individuals, and its prevalence varies depending on the studied population. Given that information on CD in Latin America is scarce, we aimed to investigate the prevalence of CD in this region of the world through a systematic review and meta-analysis. Methods and Findings This was a two-phase study. First, a cross-sectional analysis from 981 individuals of the Colombian population was made. Second, a systematic review and meta-regression analysis were performed following the Preferred Reporting Items for Systematic Meta- Analyses (PRISMA) guidelines. Our results disclosed a lack of celiac autoimmunity in the studied Colombian population (i.e., anti-tissue transglutaminase (tTG) and IgA anti-endomysium (EMA)). In the systematic review, 72 studies were considered. The estimated prevalence of CD in Latin Americans ranged between 0.46% and 0.64%. The prevalence of CD in first-degree relatives of CD probands was 5.5%. The coexistence of CD and type 1 diabetes mellitus varied from 4.6% to 8.7%, depending on the diagnosis methods (i.e., autoantibodies and/or biopsies). Conclusions Although CD seems to be a rare condition in Colombians; the general prevalence of the disease in Latin Americans seemingly corresponds to a similar scenario observed in Europeans.

    Intestinal inflammation and symptoms of celiac disease (CD) usually respond well to gluten withdrawal, but rare cases are refractory to diet. Two types of refractory CD are discriminated on the basis of the presence or absence of an atypical population of mucosal lymphocytes that may progress to enteropathy-associated T-cell lymphoma. Challenges remain in the secure diagnosis of both types of refractory disease, and evidence on which to base treatment recommendations is flawed by the small numbers of reported patients and the use of different diagnostic strategies. Recent advances in our understanding of the mechanisms of the condition in conjunction with the development of immunomodulatory agents for managing other inflammatory diseases are helping to shape future approaches to targeted therapy. Progression will depend on collaboration and recruitment to trials. In the meantime, there is evidence to suggest that earlier diagnosis and better follow-up and management of CD may prevent the development of refractoriness. PMID:27536154

    BACKGROUND: Celiac disease (CD) is a common autoimmune disorder with an increasing prevalence, including in ethnic minorities. OBJECTIVE: To report the frequency of CD diagnosis in ethnic minorities presenting to a Canadian pediatric celiac clinic and to determine whether ethnic differences exist at diagnosis or follow-up. METHODS: Patients with biopsy-proven CD diagnosed at a multidisciplinary celiac clinic between 2008 and 2011 were identified through the clinic database. Data at referral, and six-month and 12-month follow-ups were collected. These included demographics, self-reported ethnicity, symptoms, anthropometrics and laboratory investigations, including serum immunoglobulin antitissue transglutaminase (aTTG). RESULTS: A total of 272 patients were identified; 80% (n=218) were Caucasian (group 1) and 20% (n=54) were other ethnicities. South Asians (group 2) comprised 81% (n=44) of the minority population. No differences in age or sex were found between the two groups. Group 1 patients presented more often with gastrointestinal symptoms (71% versus 43%; P<0.001), while patients in group 2 presented more often with growth concerns (21% versus 68%; P<0.001). At diagnosis, serum aTTG level was consistently lower in group 1 compared with group 2 (367 IU/mL versus 834 IU/mL; P=0.030). Both groups reported symptom improvement at six months and one year. At the end of one year, aTTG level was more likely to be normal in group 1 compared with group 2 (64% versus 29%; P<0.001). CONCLUSION: Although they represent a minority group, South Asian children comprised a significant proportion of CD patients presenting to a Canadian celiac clinic. South Asian children were more likely to present with growth concerns, which has important implications for timely diagnosis in this population. In addition, the apparent delay in normalization of aTTG levels suggests that careful follow-up and culturally focused education supports should be developed for South Asian children with

    The clinical presentation of celiac disease has evolved from chronic diarrhea and malnutrition to mild nutrient insufficiencies. Recently diagnosed adults with celiac disease should be assessed for micronutrient deficiencies because early institution of a gluten-free diet (GFD) prevents morbidity and reduces the incidence of gastrointestinal malignant neoplasms and osteoporosis. In this report, we present the case of a 49-year-old woman of Southeast Asian-Indian descent living in the United States who had folate insufficiency, as manifested by low serum and red blood cell (RBC) folate levels. Further investigation, including serologic testing and intestinal biopsy, confirmed a diagnosis of celiac disease and other nutrient deficiencies. Managing the condition of this patient with folate supplements and implementation of a recommended GFD reversed the folate insufficiency. In conclusion, when serum and/or RBC levels are low in a person of Southeast Asian-Indian descent living in a country with folate fortification of the grain supply, such as the United States, the medical team needs to look for an organic cause, as in our patient, to diagnose and manage celiac disease early and, hopefully, forestall complications.

    A variety of signs and symptoms have been reported in regards to the typical and atypical presentations of CD. It is now well recognised that its onset may occur at any age and that atypical forms of CD are much more prevalent than its classic form (1).In this case, where the patient presented with high BMI and evidence of grade I of fatty liver disease, CD was suspected due to mildly abnormal bloating, cryptogenic hypertransaminasemia, abnormal LFT and poor response to fatty liver treatment. This presentation type is not uncommon; diagnosis was confirmed by the presence of subtotal villous atrophy in the biopsy specimen, positive specific antibody screening (AGA, tTG and EMA antibodies), negative antibody screening and normalization of liver enzymes on a gluten-free diet (Tab. 2, Ref. 13).

    Celiac disease (CD) is an autoimmune-mediated enteropathy triggered by dietary gluten in genetically prone individuals. The current treatment for CD is a strict lifelong gluten-free diet. However, in some CD patients following a strict gluten-free diet, the symptoms do not remit. These cases may be refractory CD or due to gluten contamination; however, the lack of response could be related to other dietary ingredients, such as maize, which is one of the most common alternatives to wheat used in the gluten-free diet. In some CD patients, as a rare event, peptides from maize prolamins could induce a celiac-like immune response by similar or alternative pathogenic mechanisms to those used by wheat gluten peptides. This is supported by several shared features between wheat and maize prolamins and by some experimental results. Given that gluten peptides induce an immune response of the intestinal mucosa both in vivo and in vitro, peptides from maize prolamins could also be tested to determine whether they also induce a cellular immune response. Hypothetically, maize prolamins could be harmful for a very limited subgroup of CD patients, especially those that are non-responsive, and if it is confirmed, they should follow, in addition to a gluten-free, a maize-free diet.

    Objectives Measurement of transglutaminase autoantibodies (TGAA) is considered to be the most efficient single serologic test for celiac disease (CD) by the American Gastroenterological Association Institute. We hypothesized that a large international collaborative effort toward improving and standardizing TGAA measurement is both feasible and necessary. The primary aim of this workshop is to compare TGAA assays among various research and clinical laboratories and examine assay concordance and improve (and eventually standardize) the TGAA assay. Methods A total of 20 laboratories (5 commercial laboratories, 15 research and clinical laboratories) participated that included enzyme-linked immunosorbent assay (ELISA) and radiobinding assays. A total of 150 serum samples were distributed to each laboratory, with each laboratory receiving an equal aliquot that was coded and blinded, composed of 100 healthy control sera and 50 CD sera. Results Laboratory sensitivity ranged from 69% to 93% and specificity ranged from 96% to 100%. By receiver operator characteristic analysis, the area under the curve (C index) ranged from 0.9488 to 0.9904. When analyzing for linear correlation, r-squared was as high as 0.8882 but as low as 0.4244 for the celiac samples between different laboratories performing ELISA. Conclusions This transglutaminase autoantibody workshop allows for larger-scale international participation for the purposes of improving and eventually standardizing the TGAA assay with subsequent workshops.

    Celiac Disease (CD) is an immune-mediated enteropathy, diagnosed in the clinical practice by intestinal biopsy and the concomitant presence of a positive celiac serology. Confocal Laser Endomicroscopy (CLE) allows skilled and trained experts to potentially perform in vivo virtual histology of small-bowel mucosa. In particular, it allows the qualitative evaluation of mucosa alteration such as a decrease in goblet cells density, presence of villous atrophy or crypt hypertrophy. We present a semi-automatic method for villi detection from confocal endoscopy images, whose appearance change in case of villous atrophy. Starting from a set of manual seeds, a first rough segmentation of the villi is obtained by means of mathematical morphology operations. A merge and split procedure is then performed, to ensure that each seed originates a different region in the final segmentation. A border refinement process is finally performed, evolving the shape of each region according to local gradient intensities. Mean and median Dice coefficients for 290 villi originating from 66 images when compared to manually obtained ground truth are 80.71% and 87.96% respectively. PMID:26738184

Confocal Laser Endomicroscopy (CLE) allows skilled and trained experts to potentially perform in vivo virtual histology of small-bowel mucosa. In particular, it allows the qualitative evaluation of mucosa alteration such as a decrease in goblet cells density, presence of villous atrophy or crypt hypertrophy. We present a semi-automatic computer-based method for the detection of goblet cells from confocal endoscopy images, whose density changes in case of pathological tissue. After a manual selection of a suitable region of interest, the candidate columnar and goblet cells' centers are first detected and the cellular architecture is estimated from their position using a Voronoi diagram. The region within each Voronoi cell is then analyzed and classified as goblet cell or other. The results suggest that our method is able to detect and label goblet cells immersed in a columnar epithelium in a fast, reliable and automatic way. Accepting 0.44 false positives per image, we obtain a sensitivity value of 90.3%. Furthermore, estimated and real goblet cell densities are comparable (error: 9.7 ± 16.9%, correlation: 87.2%, R(2) = 76%). PMID:26737720

    Celiac Disease (CD) is an immune reaction to gluten containing foods such as rye, wheat and barley. This condition affects individuals with a genetic predisposition; it targets the small bowel and may cause symptoms including diarrhea, malabsorption, weight loss, abdominal pain and bloating. The diagnosis is made by serologic testing of celiac-specific antibodies and confirmed by histology. Certain endoscopic characteristics, such as scalloping, reduction in the number of folds, mosaic-pattern mucosa or nodular mucosa, are suggestive of CD and can be visualized under white light endoscopy. Due to its low sensitivity, endoscopy alone is not recommended to diagnose CD; however, enhanced visual identification of suspected mucosal abnormalities through the use of new technologies, such as narrow band imaging with magnification (NBI-ME), could assist in targeting biopsies and thereby increasing the sensitivity of endoscopy. This is a case series of seven patients with serologic and histologic diagnoses of CD who underwent upper endoscopies with NBI-ME imaging technology as part of their CD evaluation. By employing this imaging technology, we could identify patchy atrophy sites in a mosaic pattern, with flattened villi and alteration of the central capillaries of the duodenal mucosa. We refer to this epithelial pattern as "Leopard Skin Sign". Since epithelial lesions are easily seen using NBI-ME, we found it beneficial for identifying and targeting biopsy sites. Larger prospective studies are warranted to confirm our findings. PMID:25594756

    Celiac disease (CD) is a common chronic immune disease triggered by gluten. Gliadin peptides pass through the epithelial layers, either paracellularly or transcellularly, to launch a potent adaptive immune response in the lamina propria. This aberrant immune response leads to diverse gastrointestinal and extra-gastrointestinal symptoms. Currently, the only treatment for CD is a strict lifelong adherence to a gluten-free diet (GFD), which can be challenging. An early effect of gluten in CD is an increase in gut permeability. Larazotide acetate, also known as AT-1001, is a synthetic peptide developed as a permeability regulator primarily targeting CD. In vitro studies indicate that larazotide acetate is capable of inhibiting the actin rearrangement caused by gliadin and clinical studies have been conducted using this peptide as a therapy for CD.

    Celiac disease (CD) is an autoimmune enteropathy initiated and sustained by the ingestion of gluten in genetically susceptible individuals. It is caused by a dysregulated immune response toward both dietary antigens, the gluten proteins of wheat, rye, and barley, and autoantigens, the enzyme tissue transglutaminase (TG2). The small intestine is the target organ. Although routine immunochemical protocols for a laboratory diagnosis of CD are available, faster, easier-to-use, and cheaper analytical devices for CD diagnosis are currently unavailable. This review focuses on biosensors, consisting of a physicochemical transducer and a bioreceptor, as promising analytical tools for diagnosis of CD and other diseases. Examples of recently developed biosensors as well as expectations for future lines of research and development in this field are presented. PMID:27130174

    Atypical or silent celiac disease may go undiagnosed for many years and can frequently lead to loss of bone mineral density, with evolution to osteopenia or osteoporosis. The prevalence of the latter conditions, in case of new diagnosis of celiac disease, has been evaluated in many studies but, due to the variability of epidemiologic data and patient features, the results are contradictory. The aim of this study was to evaluate bone mineral density by dual-energy X-ray absorptiometry in 175 consecutive celiac patients at time of diagnosis (169 per-protocol, 23 males, 146 females; average age 38.9 years). Dual-energy X-ray absorptiometry was repeated after 1 year of gluten-free diet in those with T-score value <−1 at diagnosis. Stratification of patients according to sex and age showed a higher prevalence of low bone mineral density in men older than 30 years and in women of all ages. A 1-year gluten-free diet led to a significant improvement in lumbar spine and femoral neck mean T-score value. We propose that dual-energy X-ray absorptiometry should be performed at diagnosis of celiac disease in all women and in male aged >30 years, taking into account each risk factor in single patients.

    Background: There are little data on patient factors that impact diagnosis rates of celiac disease. This study aims to evaluate the association between patient socioeconomic status and the symptoms at diagnosis of celiac disease. Methods: A total of 872 patients with biopsy-proven celiac disease were categorized based on the presence or absence of (1) diarrhea and (2) any gastrointestinal symptoms at diagnosis. Univariate and multivariate analyses were used to assess the association between socioeconomic status and symptoms. Results: Patients without diarrhea at presentation had a higher mean per capita income (US$34,469 versus US$32,237, p = 0.02), and patients without any gastrointestinal symptoms had a higher mean per capita income (US$36,738 versus US$31,758, p < 0.01) compared with patients having such symptoms. On multivariable analysis adjusting for sex, age, autoimmune or psychiatric comorbidities, and income, per capita income remained a significant predictor of diagnosis without gastrointestinal symptoms (odds ratio: 1.71, 95% confidence interval: 1.17–2.50, p < 0.01), and it showed a trend towards significance in diagnosis without diarrhea (odds ratio: 1.40, 95% confidence interval: 0.98–2.02, p = 0.06). Conclusions: Patients with nonclassical symptoms of celiac disease are less likely to be diagnosed if they are of lower socioeconomic status. Celiac disease may be under-recognized in this population due to socioeconomic factors that possibly include lower rates of health-seeking behavior and access to healthcare. PMID:27366218

    Background and Objective Celiac disease (CD) is a common chronic autoimmune disorder. Both the manifestations of the disease and the burden of the compulsory life-long gluten-free diet (GFD) have been shown to be associated with impairment of health-related quality of life. The objectives of this study were to provide a cross-cultural adaptation of the specific quality of life “Celiac Disease Questionnaire” (CDQ) and to analyze its psychometric properties. Materials and Methods A cross-cultural French adaptation of the CDQ (F-CDQ) was obtained according to the revised international guidelines. The questionnaire was administered at baseline to 211 patients with biopsy proven CD followed-up in a single tertiary referral centre. The questionnaire was also administered after 7 days and 6 months. Reliability (intraclass correlation coefficients (ICC), Cronbach's alpha and Bland and Altman graphical analysis), validity (factorial structure and Rasch analysis, convergent validity), and responsiveness (effect size) of the F-CDQ were studied. Results The reliability of the F-CDQ was excellent with ICC and Cronbach's alpha coefficients being between 0.79 and 0.94 for the four subscales and the total score. The factorial structure and the Rasch analysis showed that the four dimensions of the original instrument were retained. Correlations with external measures (a generic measure of quality of life, an anxiety and depression instrument, a self-assessed disease severity, and clinical manifestations) were all in the expected direction confirming the validity of the instrument. Responsiveness was studied and effect sizes ≥0.20 were demonstrated for most of the subscales for patients who reported improvement or deterioration after 6 months. Conclusion The F-CDQ retains the psychometric properties of the original instrument and should be useful in cross-national surveys and to assess outcome in clinical trials involving patients with CD.

    Background Celiac disease (CD) has a strong genetic component mainly due to HLA DQ2/DQ8 encoding genes. However, a minority of CD patients are DQ2/DQ8-negative. To address this issue, we retrospectively characterized HLA haplotypes in 5,535 subjects at risk of CD (either relatives of CD patients or subjects with CD-like symptoms) referred to our center during a 10-year period. Methods We identified loci DQA1/DQB1/DRB1 by sequence-specific oligonucleotide-PCR and sequence-specific primer-PCR; anti-transglutaminase IgA/IgG and anti-endomysium IgA by ELISA and indirect immunofluorescence, respectively. Results We diagnosed CD in 666/5,535 individuals, 4.2% of whom were DQ2/DQ8-negative. Interestingly, DQ7 was one of the most abundant haplotypes in all CD patients and significantly more frequent in DQ2/DQ8-negative (38%) than in DQ2/DQ8-positive CD patients (24%) (p<0.05). Conclusion Our data lend support to the concept that DQ7 represents an additive or independent CD risk haplotype with respect to DQ2/DQ8 haplotypes but this finding should be verified in other large CD populations.

    Decreased bone mineral density (BMD) has been reported in patients with celiac disease in association with secondary hyperparathyroidism. The present study investigated whether basal parathyroid hormone (PTH) remained elevated and whether abnormalities of parathyroid function were still present in celiac disease patients treated with a gluten-free diet. Basal seric measurements of calcium and phosphate homeostasis and BMD were obtained in 17 biopsy-proven patients under treatment for a mean period of 5.7+/-3.7 years (range 1.1 to 15.9). In addition, parathyroid function was studied with calcium chloride and sodium citrate infusions in seven patients. Basal measurements of patients were compared with those of 26 normal individuals, while parathyroid function results were compared with those of seven sex- and age-matched controls. Basal results were similar in patients and controls except for intact PTH (I-PTH) (3.77+/-0.88 pmol/L versus 2.28+/-0.63 pmol/L, P<0.001), which was higher in the former group but still within normal limits. Mean 25-hydroxy vitamin D and 1,25-dihydroxy vitamin D values were normal in patients. Parathyroid function results were also found to be similar in both groups. Compared with a reference population of the same age (Z score), patients had significantly lower BMDs of the hip (-0.60+/-0.96 SDs, P<0.05) and lumbar spine (-0.76+/-1.15 SDs, P<0.05). T scores were also decreased for the hip (-1.3+/-0.9 SDs, P<0.0001) and lumbar spine (-1.4+/-1.35 SDs, P<0.0001), with two to three patients being osteoporotic (T score less than -2.5 SDs) and seven to eight osteopenic (T score less than -1 SDs but greater than or equal to -2.5 SDs) in at least one site. Height and weight were the only important determinants of BMD values by multivariate or logistical regression analysis in these patients. The results show higher basal I-PTH values with normal parathyroid function in treated celiac disease. Height and weight values are, but I-PTH values are not

    Experience suggests that many celiac patients suffer from persistent symptoms despite a long-term gluten-free diet (GFD). We investigated the prevalence and severity of these symptoms in patients with variable duration of GFD. Altogether, 856 patients were classified into untreated (n = 128), short-term GFD (1-2 years, n = 93) and long-term GFD (≥3 years, n = 635) groups. Analyses were made of clinical and histological data and dietary adherence. Symptoms were evaluated by the validated GSRS questionnaire. One-hundred-sixty healthy subjects comprised the control group. Further, the severity of symptoms was compared with that in peptic ulcer, reflux disease, inflammatory bowel disease (IBD) and irritable bowel syndrome (IBS). Altogether, 93% of the short-term and 94% of the long-term treated patients had a strict GFD and recovered mucosa. Untreated patients had more diarrhea, indigestion and abdominal pain than those on GFD and controls. There were no differences in symptoms between the short- and long-term GFD groups, but both yielded poorer GSRS total score than controls (p = 0.03 and p = 0.05, respectively). Furthermore, patients treated 1-2 years had more diarrhea (p = 0.03) and those treated >10 years more reflux (p = 0.04) than controls. Long-term treated celiac patients showed relatively mild symptoms compared with other gastrointestinal diseases. Based on our results, good response to GFD sustained in long-term follow-up, but not all patients reach the level of healthy individuals. PMID:27428994

  17. Environmental factors in the etiology of type 1 diabetes, celiac disease, and narcolepsy.

    PubMed

    Lernmark, Åke

    2016-07-01

    The etiology of human leukocyte antigen (HLA)-associated organ-specific autoimmune diseases is incomplete. In type 1 diabetes and celiac disease, the strongest associations are with the HLA-DR3-DQ2 and DR4-DQ8 haplotypes, whereas the DQB1*06:02 allele has a strong negative association. In contrast, narcolepsy, especially as recently triggered by the Pandemrix(®) H1N1 vaccine (GlaxoKlineSmith (GSK), Brentford, Middlesex, UK), did not seem to develop without at least one copy of the latter allele. The overall hypothesis is that the role of these different HLA haplotypes, especially in Finland and Sweden, is related to the immune response to infectious agents that are common in these two populations. The high incidence of both type 1 diabetes and celiac disease in Scandinavia may be the result of the HLA-DR3-DQ2 and DR4-DQ8 haplotypes, and the DQB1*06:02 allele are common because they protected people from succumbing to common infections. The timing of dissecting the autoimmune response is critical to understand the possible role of environmental factors. First, an etiological trigger may be a common virus infecting beta cells or with antigens inducing beta-cell cross reactivity. Second, an autoimmune reaction may ensue, perhaps in response to beta-cell apoptosis or autophagy, resulting in autoantigen-specific T cells and autoantibodies. It is critical in at-risk children to dissect the immune response prior to the appearance of autoantibodies in order to identify cellular reactions in response to environmental factors that are able to induce an HLA-associated immune reaction.

    Celiac disease is an inflammatory enteropathy caused by intolerance to gluten. Previous linkage studies in the Dutch, Finnish and Hungarian populations have revealed a locus on chromosome 6q21-22 conferring susceptibility to celiac disease. This locus has previously been implicated in susceptibility to other autoimmune diseases such as Crohn's disease and type 1 diabetes. We performed fine mapping on 446 independent individuals with celiac disease and 641 controls of Dutch origin, testing 872 tagging SNPs in a 22 Mb region of chromosome 6. The 12 most promising SNPs were followed up in 2071 individuals from 284 Finnish and 357 Hungarian celiac disease families to identify risk variants in this region. Multiple markers in the region were significantly associated with celiac disease in the Dutch material. Two SNPs, rs9391227 and rs4946111, were significantly associated with celiac disease in the Finnish population. The association to rs9391227 represents the strongest association signal found in the Finnish (P = 0.003, OR 0.66) as well as the combined Dutch, Finnish and Hungarian populations (P = 3.6 × 10(-5), OR 0.76). The rs9391227 is situated downstream of the HECT domain and ankyrin repeat containing, E3 ubiquitin protein ligase 1 (HACE1) gene and is contained within a region of strong linkage disequilibrium enclosing HACE1. Two additional, independent, susceptibility variants in the 6q21-22 region were also found in a meta-analysis of the three populations. The 6q21-22 region was confirmed as a celiac disease susceptibility locus and harbors multiple independent associations, some of which may implicate ubiquitin-pathways in celiac disease susceptibility.

We will briefly discuss the drugs that are under development and then shift our attention to potential trial endpoints, such as patient-reported outcomes, histology, serology, gene expression analysis and other tests. We will outline the differing requirements for proof-of-concept Phase 2 trials and Phase 3 registration trials, with a particular emphasis on current thinking in regulatory agencies. We conclude our paper with recommendations and a glossary of regulatory terms, to enable readers who are less familiar with regulatory language to take maximum advantage of this review.

Her mother reports her stomach looks "bloated. " Steven, age 7 years, is brought into the clinic because of recurrent abdominal pain with occasional constipation or diarrhea. Steven's mother had been told in the past that he probably had "irritable bowel syndrome" but changes in his diet, occasional use of a laxative, and relaxation techniques have not improved his symptoms.

    The co-occurrence of celiac disease (CD) and type 1 diabetes (T1DM) has been reported as 5-7 times more prevalent than CD alone. The clinical presentation and natural history of CD in patients with T1DM may vary considerably. Less than 10% of patients with T1DM and CD show gastrointestinal symptoms. Therefore, experts support screening for CD in T1DM patients, though there is no consensus as to the recommended frequency of screening. When stratified by time since CD diagnosis, longer follow-up and coexistence of CD are associated with significant increased risk of diabetic associated morbidity and mortality. Early CD diagnosis and treatment with a gluten-free diet are essential. PMID:26069719

  7. Gluten measurement and its relationship to food toxicity for celiac disease patients

    PubMed Central

    Lester, Diane R

    2008-01-01

    The gluten analysis of foods has long had limitations, which have precluded food standards authorities from issuing standards for gluten-free foods based on final gluten content. The Codex Alimentarius and the Food and Drug Administration have taken steps towards such standards in which they favour the R5-enzyme-linked immunosorbent assay for gluten analysis. If this method is to be widely employed, its limitations should be recognised. Above all, it should be noted the ability of R5-enzyme-linked immunosorbent assay, and other methods, to measure gluten's toxicity toward celiac disease patients is not validated clinically. Gluten is a complex mixture of proteins and its toxicity is not fully understood. Analytical methods are a valuable tool in the definition of gluten-free foods, but they should be employed with appropriate caveats in ensuring the safety of the foods. PMID:18957072

    Lane-Hamilton syndrome refers to the uncommon co-occurrence of idiopathic pulmonary hemosiderosis and celiac disease (CD). Three children aged between 7 and 14 years with IPH were detected to have co-existing non-diarrheal CD. Institution of gluten-free diet in each of the three children resulted in amelioration of the pulmonary symptoms along with improvement of anthropometric parameters and hemoglobin over a short-term follow-up period of 8-17 months. Inhaled/oral steroids and immunosuppressants could be weaned off after dietary exclusion therapy in each of the three children. Gluten free diet should be instituted in all patients diagnosed with Lane-Hamilton syndrome. It ameliorates both the pulmonary as well as the intestinal symptoms although the precise mechanism of the pulmonary response is as yet unclear. PMID:20967850

    In the present narrative review, we analyzed the relationship between seronegative celiac disease (SNCD) and immunoglobulin deficiencies. For this purpose, we conducted a literature search on the main medical databases. SNCD poses a diagnostic dilemma. Villous blunting, intraepithelial lymphocytes (IELs) count and gluten “challenge” are the most reliable markers. Immunohistochemistry/immunofluorescence tissue transglutaminase (tTG)-targeted mucosal immunoglobulin A (IgA) immune complexes in the intestinal mucosa of SNCD patients may be useful. In our experience, tTG-mRNA was similarly increased in seropositive celiac disease (CD) and suspected SNCD, and strongly correlated with the IELs count. This increase is found even in the IELs’ range of 15–25/100 enterocytes, suggesting that there may be a “grey zone” of gluten-related disorders. An immune deregulation (severely lacking B-cell differentiation) underlies the association of SNCD with immunoglobulin deficiencies. Therefore, CD may be linked to autoimmune disorders and immune deficits (common variable immunodeficiency (CVID)/IgA selective deficiency). CVID is a heterogeneous group of antibodies dysfunction, whose association with CD is demonstrated only by the response to a gluten-free diet (GFD). We hypothesized a familial inheritance between CD and CVID. Selective IgA deficiency, commonly associated with CD, accounts for IgA-tTG seronegativity. Selective IgM deficiency (sIgMD) is rare (<300 cases) and associated to CD in 5% of cases. We diagnosed SNCD in a patient affected by sIgMD using the tTG-mRNA assay. One-year GFD induced IgM restoration. This evidence, supporting a link between SNCD and immunoglobulin deficiencies, suggests that we should take a closer look at this association. PMID:26371035

    The impact of celiac disease autoimmunity on bone health is unclear. We investigated the associations of seropositivity for tissue transglutaminase antibodies (tTGA) and endomysial antibodies (EMA) with incident hip fractures using data from a prospective cohort study, Mini-Finland Health Survey. Baseline serum samples, taken in 1978-80, were tested for tTGA and EMA. Incident hip fractures up to the year 2011 were ascertained from a national hospitalization register. Associations between seropositivity and hip fractures were modeled using Cox proportional hazards regression adjusted for age, sex, body mass index, vitamin D, gamma-glutamyl transferase, smoking, and self-rated health. Our analyses were based on 6919 men and women who had no record of celiac disease or hip fracture before the study baseline. A total of 382 individuals had a hip fracture during a median follow-up of 30 years. Compared with the tTGA-negative individuals (n = 6350), tTGA-positive participants (n = 569; with hip fracture, n = 51) had a higher risk of hip fractures (hazard ratio [HR] = 1.59, 95% confidence interval [CI] 1.17, 2.14). The findings were similar for another tTGA test (n 200; with hip fracture, n = 26; HR = 2.23, 95% CI 1.49, 3.34). We found no evidence for an association between EMA positivity and hip fracture risk (HR = 0.92, 95% CI 0.34, 2.47; n = 74; with hip fracture, n = 4). In our prospective population-based study of Finnish adults, seropositivity for tTGA was associated with an increased hip fracture risk. PMID:25270967

    A defective production of protective levels of antibodies to Hepatitis B (HB) vaccine is reported to occur in 4-10% of healthy subjects and a correlation with the presence of specific human leukocyte antigen (HLA) molecules, including DQ2, which also confers genetic predisposition to celiac disease (CD) and type I diabetes mellitus (T1DM), has been suggested.   The aim of this study was to analyze the serological response to HB vaccine and measles-containing vaccines in 69 diabetic patients (T1DM), 42 patients with celiac disease (CD) and 79 healthy control subjects (CT). The median interval between the third dose of HB vaccine and serum collection was 6.8, 3.5, and 4.7 years for T1DM, CD and CT groups, respectively. 50/69 (72%) T1DM patients, 32/42 (76%) CD patients and 61/79 (77%) CT subjects showed protective anti-HBs antibodies after vaccination, with no statistically significant difference. On the contrary, a lower statistically significant difference was found in the mean HBsAb level of T1DM subjects when compared with the other two groups. No correlation between HLA DQ2 expression in T1DM and vaccine response was detected. The comparison of serological response to measles after vaccination also showed no statistically significant differences in the three groups. Contrasting results between these data and those reported in the literature might be due to differences in the time intervals between vaccination and testing. Prospective studies in pathological and healthy groups with the same age at HBV vaccination and with the same time interval for blood sample collection to determine antibody titers are necessary in order to provide more conclusive data.

  12. Celiac Disease: A Disorder Emerging from Antiquity, Its Evolving Classification and Risk, and Potential New Treatment Paradigms

    Celiac disease is a chronic genetically based gluten-sensitive immune-mediated enteropathic process primarily affecting the small intestinal mucosa. The disorder classically presents with diarrhea and weight loss; however, more recently, it has been characterized by subclinical occult or latent disease associated with few or no intestinal symptoms. Diagnosis depends on the detection of typical histopathological biopsy changes followed by a gluten-free diet response. A broad range of clinical disorders may mimic celiac disease, along with a wide range of drugs and other therapeutic agents. Recent and intriguing archeological data, largely from the Gobleki Tepe region of the Fertile Crescent, indicate that celiac disease probably emerged as humans transitioned from hunter-gatherer groups to societies dependent on agriculture to secure a stable food supply. Longitudinal studies performed over several decades have suggested that changes in the prevalence of the disease, even apparent epidemic disease, may be due to superimposed or novel environmental factors that may precipitate its appearance. Recent therapeutic approaches are being explored that may supplement, rather than replace, gluten-free diet therapy and permit more nutritional options for future management. PMID:25547088

    HLA genes represent the main risk factor in autoimmune disorders. In celiac disease (CD), the great majority of patients carry the HLA DQA1*05 and DQB1*02 alleles, both of which encode the DQ2.5 molecule. The formation of complexes between DQ2.5 and gluten peptides on antigen-presenting cells (APCs) is necessary to activate pathogenic CD4(+) T lymphocytes. It is widely accepted that the DQ2.5 genes establish the different intensities of anti-gluten immunity, depending whether they are in a homozygous or a heterozygous configuration. Here, we demonstrated that HLA DQA1*05 and DQB1*02 gene expression is much higher than expression of non-CD-associated genes. This influences the protein levels and causes a comparable cell surface exposure of DQ2.5 heterodimers between DQ2.5 homozygous and heterozygous celiac patients. As a consequence, the magnitude of the anti-gluten CD4(+) T cell response is strictly dependent on the antigen dose and not on the DQ2.5 gene configuration of APCs. Furthermore, our findings support the concept that the expression of DQ2.5 genes is an important risk factor in celiac disease. The preferential expression of DQ2.5 alleles provides a new functional explanation of why these genes are so frequently associated with celiac disease and with other autoimmune disorders.

    AIM: To investigate risk factors for low bone mineral density (BMD) in celiac disease (CD) patients, focusing on circulating autoantibodies against osteoprotegerin (OPG). METHODS: Seventy asymptomatic CD adult patients on gluten-free diet (GFD) and harbouring persistent negative CD-related serology were recruited. Conventional risk factors for osteoporosis (e.g., age, sex, menopausal status, history of fractures, smoke, and body mass index) were checked and BMD was assessed by dual energy X ray absorptiometry. Serum calcium and parathyroid hormone (PTH) levels were evaluated. Thirty-eight patients underwent repeat duodenal biopsy. Serum samples from a selected sub-group of 30 patients, who were also typed for human leukocyte antigen (HLA) DQ2 and DQ8 haplotype, were incubated with homodimeric recombinant human OPG and tested by western blotting with an anti-OPG antibody after immunoprecipitation. RESULTS: Despite persistent negative CD-related serology and strict adherence to GFD, 49 out of the 70 (74%) patients displayed low BMD. Among these patients, 13 (24%) showed osteoporosis and 36 (76%) osteopenia. With the exception of age, conventional risk factors for osteoporosis did not differ between patients with normal and low BMD. Circulating serum calcium and PTH levels were normal in all patients. Duodenal mucosa healing was found in 31 (82%) out of 38 patients who underwent repeat duodenal biopsy with 20 (64%) still displaying low BMD. The remaining 7 patients had an incomplete normalization of duodenal mucosa with 6 (84%) showing low BMD. No evidence of circulating antibodies against OPG was found in the serum of 30 celiac patients who were tested for, independent of BMD, duodenal histology, and HLA status. CONCLUSION: If any, the role of circulating autoantibodies against OPG in the pathogenesis of bone derangement in patients with CD is not a major one. PMID:22529691

  15. Robust spectral analysis of videocapsule images acquired from celiac disease patients

    PubMed Central

    2011-01-01

    Background Dominant frequency (DF) analysis of videocapsule endoscopy images is a new method to detect small intestinal periodicities that may result from mechanical rhythms such as peristalsis. Longer periodicity is related to greater image texture at areas of villous atrophy in celiac disease. However, extraneous features and spatiotemporal phase shift may mask DF rhythms. Method The robustness of Fourier and ensemble averaging spectral analysis to compute DF was tested. Videocapsule images from the distal duodenum of 11 celiac patients (frame rate 2/s and pixel resolution 576 × 576) were analyzed. For patients 1, 2, ... 11, respectively, a total of 10, 11, ..., 20 sequential images were extracted from a randomly selected time epoch. Each image sequence was artificially repeated to 200 frames, simulating periodicities of 0.2, 0.18, ..., 0.1Hz, respectively. Random white noise at four different levels, spatiotemporal phase shift, and frames with air bubbles were added. Power spectra were constructed pixel-wise over 200 frames, and an average spectrum was computed from the 576 × 576 individual spectra. The largest spectral peak in the average spectrum was the estimated DF. Error was defined as the absolute difference between actual DF and estimated DF. Results For Fourier analysis, the mean absolute error between estimated and actual DF was 0.032 ± 0.052Hz. Error increased with greater degree of random noise imposed. In contrast, all ensemble average estimates precisely predicted the simulated DF. Conclusions The ensemble average DF estimate of videocapsule images with simulated periodicity is robust to noise and spatiotemporal phase shift as compared with Fourier analysis. Accurate estimation of DF eliminates the need to impose complex masking, extraction, and/or corrective preprocessing measures. PMID:21906318

    AIM To further improve the endoscopic detection of intestinal mucosa alterations due to celiac disease (CD). METHODS We assessed a hybrid approach based on the integration of expert knowledge into the computer-based classification pipeline. A total of 2835 endoscopic images from the duodenum were recorded in 290 children using the modified immersion technique (MIT). These children underwent routine upper endoscopy for suspected CD or non-celiac upper abdominal symptoms between August 2008 and December 2014. Blinded to the clinical data and biopsy results, three medical experts visually classified each image as normal mucosa (Marsh-0) or villous atrophy (Marsh-3). The experts’ decisions were further integrated into state-of-the-art texture recognition systems. Using the biopsy results as the reference standard, the classification accuracies of this hybrid approach were compared to the experts’ diagnoses in 27 different settings. RESULTS Compared to the experts’ diagnoses, in 24 of 27 classification settings (consisting of three imaging modalities, three endoscopists and three classification approaches), the best overall classification accuracies were obtained with the new hybrid approach. In 17 of 24 classification settings, the improvements achieved with the hybrid approach were statistically significant (P < 0.05). Using the hybrid approach classification accuracies between 94% and 100% were obtained. Whereas the improvements are only moderate in the case of the most experienced expert, the results of the less experienced expert could be improved significantly in 17 out of 18 classification settings. Furthermore, the lowest classification accuracy, based on the combination of one database and one specific expert, could be improved from 80% to 95% (P < 0.001). CONCLUSION The overall classification performance of medical experts, especially less experienced experts, can be boosted significantly by integrating expert knowledge into computer-aided diagnosis

    The MICA/B genes (MHC class I chain related genes A and B) encode for non conventional class I HLA molecules which have no role in antigen presentation. MICA/B are up-regulated by different stress conditions such as heat-shock, oxidative stress, neoplasic transformation and viral infection. Particularly, MICA/B are expressed in enterocytes where they can mediate enterocyte apoptosis when recognised by the activating NKG2D receptor present on intraepithelial lymphocytes. This mechanism was suggested to play a major pathogenic role in active celiac disease (CD). Due to the importance of MICA/B in CD pathogenesis we studied their expression in duodenal tissue from CD patients. By immunofluorescence confocal microscopy and flow cytometry we established that MICA/B was mainly intracellularly located in enterocytes. In addition, we identified MICA/B+ T cells in both the intraepithelial and lamina propria compartments. We also found MICA/B+ B cells, plasma cells and some macrophages in the lamina propria. The pattern of MICA/B staining in mucosal tissue in severe enteropathy was similar to that found in in vitro models of cellular stress. In such models, MICA/B were located in stress granules that are associated to the oxidative and ER stress response observed in active CD enteropathy. Our results suggest that expression of MICA/B in the intestinal mucosa of CD patients is linked to disregulation of mucosa homeostasis in which the stress response plays an active role.

    Celiac disease (CD) is a chronic disease causing the inflammation of the proximal small intestine, in genetically predisposed individuals. This is triggered by the consumption of the gluten protein and the side effects of the disease are mitigated by a lifelong gluten-free diet (GFD) treatment. The predominant consequence of CD is malnutrition due to malabsorption (with diarrhea, weight loss, nutritional deficiencies, and altered blood parameters), especially in patients who do not show strict adherence to GFD treatment. Recent evidence shows that, despite a lifelong GFD, some functional disorders persist, such as compromised gallbladder function and motility, exocrine pancreatic insufficiency, increased gut permeability, small-intestinal bowel overgrowth, nonalcoholic fatty liver disease (NAFLD), lactose intolerance, and milk allergy. These abnormalities may predispose to the occurrence of overweight and obesity even in CD patients. This review focuses on the principal functional and metabolic disorders in both treated and untreated CD, ranging from alterations of the gastrointestinal system to impaired glucose and lipid metabolism and insulin secretion with the aim of providing new implications beyond a GFD, for an ad hoc nutrition treatment in these patients.

    2016-05-01

    We propose a biochemical mechanism for celiac disease and non-celiac gluten sensitivity that may rationalize many of the extradigestive disorders not explained by the current immunogenetic model. Our hypothesis is based on the homology between the 33-mer gliadin peptide and a component of the NMDA glutamate receptor ion channel - the human GRINA protein - using BLASTP software. Based on this homology the 33-mer may act as a natural antagonist interfering with the normal interactions of GRINA and its partners. The theory is supported by numerous independent data from the literature, and provides a mechanistic link with otherwise unrelated disorders, such as cleft lip and palate, thyroid dysfunction, restless legs syndrome, depression, ataxia, hearing loss, fibromyalgia, dermatitis herpetiformis, schizophrenia, toxoplasmosis, anemia, osteopenia, Fabry disease, Barret's adenocarcinoma, neuroblastoma, urinary incontinence, recurrent miscarriage, cardiac anomalies, reduced risk of breast cancer, stiff person syndrome, etc. The hypothesis also anticipates better animal models, and has the potential to open new avenues of research.

    A 70-year-old woman with celiac disease presented with weight loss and diarrhea unresponsive to gluten-free diet (GFD) and prednisone. Diagnosis of type 2 refractory celiac disease (RCD) was made by small intestinal biopsies showing severe villous blunting and intraepithelial lymphocytosis. She was diagnosed with hemophagocytic lymphohistiocytic syndrome (HLH) after developing fever, pancytopenia, hypofibrinogenemia, elevated ferritin, and demonstration of hemophagocytosis on her bone marrow biopsy. An expert pathologist on lymphoma reviewed her biopsies and revised the final diagnosis to type 1 enteropathy-associated T-cell lymphoma (EATL) based on large T-cells infiltrating the lamina propria. We describe the first case of HLH associated with localized EATL and RCD. PMID:26157854

    Celiac disease (CD) is an autoimmune enteropathy triggered by gluten ingestion and characterized by circulating anti-transglutaminase type 2 (anti-TG2) autoantibodies. An epidemiological link between maternal CD and increased risk of pregnancy failure has been established; however, the mechanism underlying this association is still poorly understood. Because proper endometrial angiogenesis and decidualization are prerequisites for placental development, we investigated the effect of anti-TG2 antibodies on the process of endometrial angiogenesis. Binding of anti-TG2 antibodies to human endometrial endothelial cells (HEECs) was evaluated by ELISA. Angiogenesis was studied in vitro on HEECs and in vivo in a murine model. In particular, we investigated the effect of anti-TG2 antibodies on HEEC matrix metalloprotease-2 (MMP-2) activity by gelatin zymography, cytoskeletal organization and membrane properties by confocal microscopy, and activation of extracellular signal-regulated kinases (ERKs) and focal adhesion kinase (FAK) by Western blot analysis. Anti-TG2 antibodies bound to HEECs and decreased newly formed vessels both in vitro and in vivo. Anti-TG2 antibodies impaired angiogenesis by inhibiting the activation of MMP-2, disarranging cytoskeleton fibers, changing the physical and mechanical properties of cell membranes, and inhibiting the intracellular phosphorylation of FAK and ERK. Anti-TG2 antibodies inhibit endometrial angiogenesis affecting the TG2-dependent migration of HEECs and extracellular matrix degradation, which are necessary to form new vessels. Our results identify pathogenic mechanisms of placental damage in CD. PMID:23966323

    Background Most antibodies recognize conformational or discontinuous epitopes that have a specific 3-dimensional shape; however, determination of discontinuous B-cell epitopes is a major challenge in bioscience. Moreover, the current methods for identifying peptide epitopes often involve laborious, high-cost peptide screening programs. Here, we present a novel microarray method for identifying discontinuous B-cell epitopes in celiac disease (CD) by using a silicon-based peptide array and computational methods. Methods Using a novel silicon-based microarray platform with a multi-pillar chip, overlapping 12-mer peptide sequences of all native and deamidated gliadins, which are known to trigger CD, were synthesized in situ and used to identify peptide epitopes. Results Using a computational algorithm that considered disease specificity of peptide sequences, 2 distinct epitope sets were identified. Further, by combining the most discriminative 3-mer gliadin sequences with randomly interpolated3- or 6-mer peptide sequences, novel discontinuous epitopes were identified and further optimized to maximize disease discrimination. The final discontinuous epitope sets were tested in a confirmatory cohort of CD patients and controls, yielding 99% sensitivity and 100% specificity. Conclusions These novel sets of epitopes derived from gliadin have a high degree of accuracy in differentiating CD from controls, compared with standard serologic tests. The method of ultra-high-density peptide microarray described here would be broadly useful to develop high-fidelity diagnostic tests and explore pathogenesis. PMID:26824466

    It has previously been demonstrated that the circulating levels of TNF-related apoptosis-inducing ligand (TRAIL) are significantly lower in patients with type 1 diabetes (T1D) than in normal age- and gender-matched controls. Since celiac disease (CD) is often associated with T1D, a retrospective study was performed to analyze the sera of a cohort of pediatric subjects: i) patients with CD at onset (n=100); ii) patients with potential CD (n=45); iii) patients with CD associated with other auto-immune diseases (n=17); and iv) patients with eosinophilic esophagitis (n=15). Among the patients with CD, 49 were also analyzed after six months on a gluten-free diet, while data were also available for 13 patients after one year on a gluten-free diet. No significant differences were found in the circulating levels of TRAIL between the patients with CD and the patients with either eosinophilic esophagitis or potential CD. Patients with CD associated with other auto-immune diseases showed significantly lower levels of TRAIL when compared with patients with CD alone. The gluten-free diet did not significantly modify the levels of circulating TRAIL at 6 or 12 months. Thus, although T1D and CD share common immunological features, the circulating levels of TRAIL show a significant difference between the two pathologies, and do not appear to be modulated in CD.

    The question about recommending pure, noncontaminated oats as part of the gluten-free diet of patients with celiac disease remains controversial. This might be due to gluten cross contamination and to the possible immunogenicity of some oat cultivars. In view of this controversy, a review of the scientific literature was conducted to highlight the latest findings published between 2008 and 2014 to examine the current knowledge on oats safety and celiac disease in Europe and North America. Results showed that regular oats consumed in Canada are largely contaminated. Overall, the consumption of pure oats has been generally considered to be safe for adults and children. However, it appears that some oat cultivars may trigger an immune response in sensitive individuals. Therefore, further long-term studies on the impact of consumption of oats identifying the cultivar(s) constitute an important step forward for drawing final recommendations. Furthermore, a closer and more accurate monitoring of the dietary intake of noncontaminated oats would be paramount to better determine what its actual contribution in the gluten-free diet of adults and children with celiac disease are in order to draw sound recommendations on the safety of pure oats as part of the gluten-free diet.

    Systemic lupus erythematosus (SLE) is a serious and potentially fatal syndrome characterized by an autoimmune assault on various organs and systems that may include the skin, joints, central nervous system, heart and kidneys. Recent research shows that gluten sensitivity causes more than just celiac disease and gluten has been linked to numerous autoimmune conditions. We report here a 6-year-old girl presenting with malaise, abdominal pain, loss of appetite, abdominal distension. After three weeks she developed other symptoms such as arthralgias, malar rash, being finally diagnosed with SLE and possible autoimmune hepatitis. The suspicion of celiac disease was based on a combination of symptoms (poor growth, iron deficiency anemia, chronic abdominal pain, abdominal distension, constipation, "sad child"), IgA deficiency, in the presence of SLE diagnosis. Positive diagnosis of celiac disease was confirmed by the presence of an anti IgG anti-transglutaminase antibodies titer of 120 EU/ml (normally less than 20 EU/ml). Small bowel biopsy showed a IIIB1 stage according to the Marsh classification. Three methylprednisolone pulses were promptly administered, followed by oral prednisone (2 mg/kg bw/day) with a good outcome. PMID:25970948

    A hallmark of celiac disease is autoantibodies to transglutaminase 2 (TG2). By visualizing TG2-specific antibodies by antigen staining of affected gut tissue, we identified TG2-specific plasma cells in the lamina propria as well as antibodies in the subepithelial layer, inside the epithelium, and at the brush border. The frequency of TG2-specific plasma cells were found not to correlate with serum antibody titers, suggesting that antibody production at other sites may contribute to serum antibody levels. Upon commencement of a gluten-free diet, the frequency of TG2-specific plasma cells in the lesion dropped dramatically within 6 months, yet some cells remained. The frequency of TG2-specific plasma cells in the celiac lesion is thus dynamically regulated in response to gluten exposure. Laser microdissection of plasma cell patches, followed by antibody gene sequencing, demonstrated that clonal cells were seeded in distinct areas of the mucosa. This was confirmed by immunoglobulin heavy chain repertoire analysis of plasma cells isolated from individual biopsies of two untreated patients, both for TG2-specific and non-TG2-specific cells. Our results shed new light on the processes underlying the B-cell response in celiac disease, and the approach of staining for antigen-specific antibodies should be applicable to other antibody-mediated diseases.

    Background and aims: Severe villous atrophy can be revealed with conventional white light endoscopy (WLE), however, milder grades or patchy villous atrophy are more difficult to detect. Novel endoscopic techniques such as high definition i-SCAN endoscopy with the water immersion technique (i-SCAN-HDWI) may provide the ability to visualize duodenal villi more accurately. We aimed to determine the performance of i-SCAN-HDWI in evaluating the severity of histological damage in the duodenum of patients with celiac disease. Patients and methods: A retrospective cohort study was performed in a single tertiary academic endoscopic center. We studied 58 patients (46 women; median age 36.5 years, range 18 – 72 years) with positive anti-TTG IgA antibody. The villous pattern of the second part of the duodenum was assessed by WLE and i-SCAN-HDWI. The endoscopic grades in both techniques were correlated using Marsh histologic grades by Spearman correlation coefficient. The diagnostic accuracy of i-SCAN-HDWI for detection of patchy or complete atrophy of the villi was evaluated. Results: A significant correlation was demonstrated between endoscopic grade using i-SCAN-HDWI and Marsh histologic grade (r = 0.732; P < 0.00001). The correlation between WLE grade and Marsh histologic grade was inferior to i-SCAN-HDWI (r = 0.31; P = 0.01). The sensitivity of i-SCAN-HDWI was 96 % (95 %CI: 85 – 99 %) and the specificity was 63 % (95 %CI: 26 – 90 %) in diagnosing abnormal biopsy consistent with celiac disease. Conclusion: i-SCAN-HDWI endoscopy can reflect the histological severity of celiac disease more accurately than conventional WLE alone. This novel endoscopic imaging can improve the diagnostic yield of duodenal biopsies in celiac patients, especially for those with a patchy distribution of villous damage. PMID:27227112

    Background Association of the interleukin-23 receptor (IL23R) with inflammatory bowel disease (IBD) has been confirmed in several populations. IL23R also associates with psoriasis, suggesting that the gene may be an important candidate for many chronic inflammatory diseases. Methods We studied association of single-nucleotide variants in IL23R with IBD in Swedish patients, in both Crohn's disease (CD) and ulcerative colitis (UC) subsets. The same genetic variants were also studied in Finnish patients with psoriasis or celiac disease, and in Hungarian and Italian patients with celiac disease. Results Association of IL23R with IBD was replicated in our Swedish patients, and linkage and association of the IL23R region with psoriasis was found in the Finnish population. The IL23R region was also linked to celiac disease in Finnish families, but no association of IL23R variants with celiac disease was found in the Finnish, Hungarian or Italian samples. Conclusion Our study is the first to demonstrate association of IL23R with CD and UC in Swedish patients with IBD. It is also the first study to report linkage and association of the IL23R region with psoriasis in the Finnish population. Importantly, this is the first report of linkage of the IL23R region to celiac disease, a chronic inflammatory condition in which IL23R has not been previously implicated. PMID:19175939

    Celiac disease (CD) or gluten-sensitive enteropathy is strongly associated with HLA-DQ alleles; more than 95% of patients are DQB1*02. However, the uniform association with HLA-DQ alleles does not explain the clinical heterogeneity, especially the wide range in the age of onset of CD. We asked whether the age of onset of CD is also influenced by class I genes of the human MHC. We performed HLA typing in three groups of patients suffering from CD. The age of onset in the first group (N = 200) was before 15 years of age, in the second group (N = 62) between 15 and 40 years, in the third group (N = 59) after 40 years. We observed a statistically significant increase in the frequencies of HLA-B8 and Cw7 with increasing age of onset. In conclusion, we conclude that distinct alleles from the class I region of the human MHC might lead to late onset of CD. In particular, relatives of CD patients with the disease-prone HLA class I alleles HLA-B8 and Cw7 should be followed up carefully for late onset of CD. PMID:12757179

    Celiac disease (CD) is a food-related disease caused by certain gluten peptides containing T-cell stimulating epitopes from wheat, rye, and barley. CD-patients have to maintain a gluten-free diet and are therefore dependent on reliable testing and labeling of gluten-free products. So far, the R5-ELISA is the approved method to detect if food products can be labeled gluten-free. Because the R5-ELISA detects gluten in general, there is a demand for an improved detection method that quantifies specifically CD-epitopes. Therefore, we developed a new method for detection and quantification of CD-epitopes, based on liquid chromatography (LC) coupled to mass spectrometry (MS) in multiple reaction monitoring (MRM) mode. This method enables targeted label free comparative analysis of the gluten proteins present in different wheat varieties and species, and in wheat-based food products. We have tested our method by analyzing several wheat varieties that vary in CD-epitope content, as was shown before using immunoblotting and specific monoclonal antibodies. The results showed that a modern bread wheat variety Toronto contained the highest amounts of CD immunogenic peptides compared with the older bread wheat variety Minaret and the tetraploid wheat variety Dibillik Sinde. Our developed method can detect quantitatively and simultaneously multiple specific CD-epitopes in a high throughput manner. PMID:25795397

    As the gluten-free diet (GFD) gains in popularity with the general public, health practitioners are beginning to question its real health benefits. For those patients with celiac disease (CD), the GFD is considered medical nutrition therapy, as well as the only proven treatment that results in improvements in symptomatology and small bowel histology. Those with wheat allergy also benefit from the GFD, although these patients often do not need to restrict rye, barley, and oats from their diet. Gluten sensitivity is a controversial subject, where patients who have neither CD nor wheat allergy have varying degrees of symptomatic improvement on the GFD. Conditions in this category include dermatitis herpetiformis (DH), irritable bowel syndrome (IBS), and neurologic diseases such as gluten-sensitive ataxia and autism. It is important for patients and healthcare practitioners to understand the differences between these conditions, even though they may all respond to a GFD. Patients with CD can experience comorbid nutrition deficiencies and are at higher risk for the development of cancers and other autoimmune conditions. Those with wheat allergy and gluten sensitivity are thought not to be at higher risk for these complications. Defining the symptoms and biochemical markers for gluten-sensitive conditions is an important area for future investigations, and high-quality, large-scale randomized trials are needed to prove the true benefits of the GFD in this evolving field.

    Background Dilated cardiomyopathy (DCM) is a rare disease of largely unknown origin. Previous studies have suggested an increased prevalence of celiac disease (CD) in patients with DCM. These studies, however, were based on a maximum of 5 patients with both CD and DCM. In the present large Swedish population-based cohort study, we examined the risk of idiopathic DCM in patients with CD determined by small-intestinal histopathology. Methods and Results From 2006 to 2008, we collected duodenal/jejunal biopsy data on CD (equal to villous atrophy, Marsh stage 3, n=29 071 unique individuals) from (all) 28 pathology departments in Sweden. These individuals were compared with 144 429 reference individuals matched for age, sex, calendar year, and county. Data on DCM were obtained through the National Patient Register and confirmed by patient charts and echocardiography data. During follow-up, 17 patients with CD and 52 reference individuals developed idiopathic DCM. Thus, patients with CD were at an increased risk of idiopathic DCM (hazard ratio, 1.73; 95% confidence interval, 1.00 to 3.00), although the risk estimate failed to attain statistical significance (P=0.052). Conclusion This nationwide study found a moderately but not statistically significantly increased risk of idiopathic DCM in patients with biopsy-verified CD.

    Objective: To determine the prevalence of celiac disease (CD) in children with type 1 diabetes mellitus (TIDM) in follow-up in a Tertiary Care Referral Centre in Western India and to describe the clinical features indicative of CD in screened patients of TIDM. Study Design: In this single center observational cross-sectional study, 71 children who were diagnosed with TIDM were subjected to screening for CD with tissue transglutaminase antibody testing. Those who tested positive were offered intestinal biopsy for the confirmation of diagnosis. Clinical profiles of both groups of patients were compared and manifestations of CD were delineated. Results: The study revealed the prevalence of CD (based on serology) in children with Type 1 diabetes as 15.49%. The prevalence of biopsy-confirmed CD was 7.04%. Of the diagnosed CD patients, one-third were symptomatic at the time of screening while the majority was asymptomatic. The major clinical features indicative of CD were intestinal symptoms, anemia, rickets, and short stature. Autoimmune thyroid disease was prevalent in 29.6% of the patients with TIDM followed by CD. Conclusions: The high prevalence of CD in children with Type 1 diabetes emphasizes the need for routine screening programs to be in place for these high-risk populations. The clinical profile of patients with CD further elaborates the indicators of CD and the need to screen for them. PMID:26693431

    Objective. Aim of the study was to determine the prevalence of autoimmune thyroid disease, persistence of antithyroid antibodies, effect of gluten-free diet, and long-term outcome of thyroid function in pediatric patients with celiac disease (CD). Methods. 67 patients with CD aged from 1 year to 16 years were screened for thyroid antithyroperoxidase, antithyroglobulin and anti-TSH receptor antibodies, serum free triiodothyronine, free thyroxine, and thyroid-stimulating hormone (TSH) at diagnosis and during follow-up. Results. None of the patients had antithyroid antibodies at diagnosis. Antithyroid antibodies became positive in 16.4% of the patients (11/67) 2 to 3 years after the diagnosis of CD. Clinical hypothyroidism was observed only in 3 of 11 CD patients with positive antithyroid antibodies (27.2%). The antithyroid antibodies positive and negative patients did not differ significantly according to compliance to GFD (P > 0.05). A statistically significant difference was observed only in age, in which the patients with positive antithyroid antibodies were younger than the patients with negative antithyroid antibodies (P = 0.004). None of the patients had any change in their thyroid function and antibody profile during their follow-up. Conclusion. Antithyroid antibodies were detected in younger pediatric patients with CD and the prevalence of antithyroid antibodies did not correlate with the duration of gluten intake. PMID:25788942

    Gluten-free diet (GFD) is the cornerstone treatment for celiac disease (CD). This diet excludes the protein gluten a protein forum in in grains such as wheat, barley, rye and triticale. Gluten causes small intestines inflammation in patients with CD and eating a GFD helps these patients in controlling signs and symptoms and prevent complications. Following a GFD may be frustrating, however, it is important to know that plenty of foods are naturally gluten-free and nowadays is relatively easy to find substitutes for gluten-containing foods. Certain grains, such as oats, are generally safe but can be contaminated with wheat during growing and processing stages of production. For this reason, it is generally recommended avoiding oats unless they are specifically labelled gluten-free. Other products that may contain gluten include food additives, such as malt flavouring, modified food starch and some supplement and/or vitamins that use gluten as a binding agent. Cross-contamination occurs when gluten-free foods come into contact with foods that contain gluten. It can happen during the manufacturing process or if the same equipment is used to make a variety of products. Cross-contamination can also occur at home if foods are prepared on common surfaces or with utensils that have not been cleaned after being used to prepare gluten-containing foods (using a toaster for gluten-free and regular bread). Although safe and effective, the GFD is not ideal: it is expensive, of limited nutritional value, and not readily available in many countries. Consequently, a need exists for novel, non-dietary therapies for celiac disease. Advances in understanding the immunopathogenesis of CD have suggested several types of therapeutic strategies alternative to the GFD. Some of these strategies attempt to decrease the immunogenicity of gluten-containing grains by manipulating the grain itself or by using oral enzymes to break down immunogenic peptides that normally remain intact during

    Adult celiac disease (CD) presents with very diverse symptoms that are clearly different from those typically seen in pediatric patients, including ferropenic anemia, dyspepsia, endocrine alterations and elevated transaminase concentration. We present the case of a 51-year-old overweight woman with altered basal blood glucose, hypercholesterolemia, hypertriglyceridemia and persisting elevated transaminase levels, who showed all the symptoms for a diagnosis of metabolic syndrome. Because she presented iron deficiency anemia, she was referred to the gastroenterology department and subsequently diagnosed with celiac disease after duodenal biopsies and detection of a compatible HLA haplotype. Gluten-free diet (GFD) was prescribed and after 6 mo the patient showed resolution of laboratory abnormalities (including recovering anemia and iron reserves, normalization of altered lipid and liver function parameters and decrease of glucose blood levels). No changes in weight or waist circumference were observed and no significant changes in diet were documented apart from the GFD. The present case study is the first reported description of an association between CD and metabolic syndrome, and invites investigation of the metabolic changes induced by gluten in celiac patients.

    2013-01-01

    Background Prevalence of celiac disease in developed countries is assessed about 1:100–1:150. The real prevalence is unknown because mass screenings are expensive and difficult to organize. Moreover celiac disease can affect people at every age and studies on asymptomatic subjects at different ages are not comparable. In this study we wanted to know the real prevalence of celiac disease in children in the Republic of San Marino. We also analysed concordance of different tests used and costs of mass screening. Methods The study started in 1993. From 1993 to 1997 children aged 6, 10 and 14 were screened. Since 1997 only children aged 6 were monitored, in order to have a homogeneous population. In fact, every child born since 1980 was taken into account. Children were recruited by classroom lists of students for general paediatric examination. Until 2005 the screening test was based on dosage of antibodies anti-gliadin (AGA) IgA and IgG on venous blood. Since 2006 these tests were replaced by anti-transglutaminase IgA antibodies (ATTG). Anti-endomysial antibodies (EMA) were performed if result of any between either AGA or ATTG tests was positive or borderline; if EMA was positive, then an endoscopy with histological examination was performed to confirm the final diagnosis. Results Attendance to paediatric examination was 96%, submission to blood test was 87%. 42 on 5092 (0,8%; 1:125) children resulted affected by celiac disease. Histology always confirmed diagnosis by serology except for two cases. AGA test (until 2005) yielded 28 on 4304 (0,7% 1:143); ATTG test (since 2006) revealed 14 positive cases on 788 (1,8%; 1:55) leading to a larger percentage of diagnosis. EMA antibodies always confirmed positivity of ATTG. Conclusions Prevalence of celiac disease in children of Republic of San Marino is comparable to other North-European Countries. Sensitivity of ATTG proved much higher than that of anti-gliadin antibodies. Concordance between ATTG and EMA was 100

    Practical application of genomic-based risk stratification to clinical diagnosis is appealing yet performance varies widely depending on the disease and genomic risk score (GRS) method. Celiac disease (CD), a common immune-mediated illness, is strongly genetically determined and requires specific HLA haplotypes. HLA testing can exclude diagnosis but has low specificity, providing little information suitable for clinical risk stratification. Using six European cohorts, we provide a proof-of-concept that statistical learning approaches which simultaneously model all SNPs can generate robust and highly accurate predictive models of CD based on genome-wide SNP profiles. The high predictive capacity replicated both in cross-validation within each cohort (AUC of 0.87–0.89) and in independent replication across cohorts (AUC of 0.86–0.9), despite differences in ethnicity. The models explained 30–35% of disease variance and up to ∼43% of heritability. The GRS's utility was assessed in different clinically relevant settings. Comparable to HLA typing, the GRS can be used to identify individuals without CD with ≥99.6% negative predictive value however, unlike HLA typing, fine-scale stratification of individuals into categories of higher-risk for CD can identify those that would benefit from more invasive and costly definitive testing. The GRS is flexible and its performance can be adapted to the clinical situation by adjusting the threshold cut-off. Despite explaining a minority of disease heritability, our findings indicate a genomic risk score provides clinically relevant information to improve upon current diagnostic pathways for CD and support further studies evaluating the clinical utility of this approach in CD and other complex diseases.

  20. Autoantibodies against MHC class I polypeptide-related sequence A are associated with increased risk of concomitant autoimmune diseases in celiac patients

    PubMed Central

    2014-01-01

    Background Overexpression of autologous proteins can lead to the formation of autoantibodies and autoimmune diseases. MHC class I polypeptide-related sequence A (MICA) is highly expressed in the enterocytes of patients with celiac disease, which arises in response to gluten. The aim of this study was to investigate anti-MICA antibody formation in patients with celiac disease and its association with other autoimmune processes. Methods We tested serum samples from 383 patients with celiac disease, obtained before they took up a gluten-free diet, 428 patients with diverse autoimmune diseases, and 200 controls for anti-MICA antibodies. All samples were also tested for anti-endomysium and anti-transglutaminase antibodies. Results Antibodies against MICA were detected in samples from 41.7% of patients with celiac disease but in only 3.5% of those from controls (P <0.0001) and 8.2% from patients with autoimmune disease (P <0.0001). These antibodies disappeared after the instauration of a gluten-free diet. Anti-MICA antibodies were significantly prevalent in younger patients (P <0.01). Fifty-eight patients with celiac disease (15.1%) presented a concomitant autoimmune disease. Anti-MICA-positive patients had a higher risk of autoimmune disease than MICA antibody-negative patients (P <0.0001; odds ratio = 6.11). The risk was even higher when we also controlled for age (odds ratio = 11.69). Finally, we found that the associated risk of developing additional autoimmune diseases was 16 and 10 times as high in pediatric patients and adults with anti-MICA, respectively, as in those without. Conclusions The development of anti-MICA antibodies could be related to a gluten-containing diet, and seems to be involved in the development of autoimmune diseases in patients with celiac disease, especially younger ones.

    Synopsis The gastrointestinal tract provides an intriguing organ for considering the eosinophil’s role in health and disease. The normal gastrointestinal (GI) tract, except for the esophagus, is populated by eosinophils that are present throughout the mucosa in varying numbers. This latter fact raises the possibility that eosinophils participate in innate mechanisms of defense. In contrast, a number of clinical studies provide a wealth of data that associates increased numbers of eosinophils with inflammatory GI diseases; these findings prompt concerns that eosinophils may have a deleterious effect on the gut. In this article we present clinical features of 4 disease processes that have been associated with eosinophilia and suggest areas requiring investigation as to their clinical significance and scientific relevance.

    Objectives There are significant geographical differences in the prevalence and incidence of celiac disease that cannot be explained by HLA alone. More than 40 loci outside of the HLA region have been associated with celiac disease. We investigated the roles of these non-HLA genes in the development of tissue transglutaminase autoantibodies (tTGA) and celiac disease in a large international prospective cohort study. Methods A total of 424,788 newborns from the US and European general populations and first-degree relatives with type 1 diabetes were screened for specific HLA genotypes. Of these, 21,589 carried 1 of the 9 HLA genotypes associated with increased risk for type 1 diabetes and celiac disease; we followed 8676 of the children in a 15 y prospective follow-up study. Genotype analyses were performed on 6010 children using the Illumina ImmunoChip. Levels of tTGA were measured in serum samples using radio-ligand binding assays; diagnoses of celiac disease were made based on persistent detection of tTGA and biopsy analysis. Data were analyzed using Cox proportional hazards analyses. Results We found 54 single-nucleotide polymorphisms (SNPs) in 5 genes associated with celiac disease (TAGAP, IL18R1, RGS21, PLEK, and CCR9) in time to celiac disease analyses (10−4>P>5.8x10−6). The hazard ratios (HR) for the SNPs with the smallest P values in each region were 1.59, 1.45, 2.23, 2.64, and 1.40, respectively. Outside of regions previously associated with celiac disease, we identified 10 SNPs in 8 regions that could also be associated with the disease (P<10−4). A SNP near PKIA (rs117128341, P = 6.5x10−8, HR = 2.8) and a SNP near PFKFB3 (rs117139146, P<2.8x10−7, HR = 4.9) reached the genome-wide association threshold in subjects from Sweden. Analyses of time to detection of tTGA identified 29 SNPs in 2 regions previously associated with celiac disease (CTLA4, P = 1.3x10−6, HR = 0.76 and LPP, P = 2.8x10−5, HR = .80) and 6 SNPs in 5 regions not previously

    It is widely recognized that the intestinal microbiota plays a role in the initiation and perpetuation of intestinal inflammation in numerous chronic conditions. Most studies report intestinal dysbiosis in celiac disease (CD) patients, untreated and treated with a gluten-free diet (GFD), compared to healthy controls. CD patients with gastrointestinal symptoms are also known to have a different microbiota compared to patients with dermatitis herpetiformis and controls, suggesting that the microbiota is involved in disease manifestation. Furthermore, a dysbiotic microbiota seems to be associated with persistent gastrointestinal symptoms in treated CD patients, suggesting its pathogenic implication in these particular cases. GFD per se influences gut microbiota composition, and thus constitutes an inevitable confounding factor in studies conducted in CD patients. To improve our understanding of whether intestinal dysbiosis is the cause or consequence of disease, prospective studies in healthy infants at family risk of CD are underway. These studies have revealed that the CD host genotype selects for the early colonizers of the infant's gut, which together with environmental factors (e.g., breast-feeding, antibiotics, etc.) could influence the development of oral tolerance to gluten. Indeed, some CD genes and/or their altered expression play a role in bacterial colonization and sensing. In turn, intestinal dysbiosis could promote an abnormal response to gluten or other environmental CD-promoting factors (e.g., infections) in predisposed individuals. Here, we review the current knowledge of host-microbe interactions and how host genetics/epigenetics and environmental factors shape gut microbiota and may influence disease risk. We also summarize the current knowledge about the potential mechanisms of action of the intestinal microbiota and specific components that affect CD pathogenesis. PMID:26287240

    Wheat is the staple cereal in many countries and its uses in manufactured foods are ever growing due to the technological qualities of gluten proteins. Transglutaminases (TG) are ubiquitous enzymes with many functions. They are able to transform proteins by deamidation and/or transamidation. This last reaction can cross-link proteins together. Intestinal tissue TG has been shown to play an important role in two kinds of immune reactions to wheat: celiac disease and wheat-dependent exercise-induced anaphylaxis. In addition, new epitopes have been suspected in cases of anaphylaxis to wheat isolates, a food ingredient consisting mainly of deamidated gluten proteins. As a microbial TG is included in many food technological processes, its safe use should be checked. This assessment must cover not only the safety of the TG itself but also that of the deamidated/cross-linked proteins generated by this enzyme. This article aims at discussing the possible consequences of using TG in food industry in the light of today knowledge about immune reactions to wheat. PMID:16528904

    Objective The incidences of celiac disease (CD) and asthma are increasing and the two conditions are associated in individuals. Risk of asthma may be passed on to the next generation through shared risk factors. We examined whether parental CD is associated with risk of asthma in offspring. Methods We conducted a population-based Danish nationwide cohort study, using medical databases, covering the period 1 January 1979 to 31 December 2009. For each child with a parental history of CD, we randomly sampled 100 children without this history from the children born in the same calendar year. We used Cox proportional-hazards regression to estimate incidence rate ratios for asthma, adjusting for measured covariates. Results We identified 1,107 children with a parental history of CD and 110,700 children without this parental history. During up to 32 years of follow-up, 6,125 children received a hospital diagnosis of asthma. The adjusted incidence rate ratio for asthma associated with a parental history of CD was 1.09 (95% confidence interval: 0.86–1.39) and was similar for maternal and paternal CD. Inclusion of asthma-medication in the definition of asthma did not substantially change the results. Conclusion There was no convincing evidence of an increased risk of asthma among offspring of parents with CD. PMID:25565892

    Background/Aim: Epidemiological studies of celiac disease (CD) among Saudi children have been performed only within some groups who are at a high risk of developing CD. The aim of this study was to determine the prevalence of CD among symptom-free children from the public schools of the military campus of National Guard in the Eastern Province of Saudi Arabia. Patients and Methods: Between 2012 and 2014, serum samples were collected from 1141 students (age 6–18 years) attending nine public schools of the military campus of National Guard in the Eastern Province of Saudi Arabia. Participants were screened for CD by testing for anti-tissue transglutaminase IgA (IgA-tTG) and IgG antibodies (IgG-tTG). Small intestinal biopsy was offered to all participants who tested positive for IgA-tTG [IgA-tTG >20 relative units (RU)/ml]. Results: Of the 1141 participants, 32 were IgA-tTG positive. Thus, the estimated serology-positive prevalence was 3%. An intestinal biopsy was performed in 10 of the participants with antibody positivity. The biopsy findings of all 10 children were consistent with CD. Thus, the estimated biopsy-confirmed prevalence was about 1%. Conclusions: The prevalence of CD was estimated to be about 1% among symptom-free children from the public schools of the military campus of National Guard in the Eastern Province of Saudi Arabia.

    Celiac disease (CD) is characterized by a chronic immune reaction in the small intestine to the gluten proteins that are present in a (Western) daily diet. Besides the well known involvement of the HLA class II histocompatibility antigen (HLA)-DQ2.5 and -DQ8 heterodimers (encoded by particular combinations of the HLA-DQA1 and -DQB1 gene) in CD and the minor contribution of the CTLA-4 gene, recently the myosin IXB (MYO9B) gene has also been found to be genetically associated. This review covers the general aspects of CD as well as current insight into important molecular aspects. We evaluate the role of susceptibility genes in CD by following gluten along its path from ingestion to uptake in the body, which leads us through the three aspects of CD's pathology. The first is the presence of gluten in the lumen of the intestine, where it is broken down by several enzymes. The second is the intestinal barrier through which gluten peptides pass. The third is the reaction of the immune system in response to gluten peptides, in which both the innate and the adaptive immune systems play a role. Our main conclusion, based on the current genetic and functional studies, is that we should look for causal genes in the barrier function as well as in the immune systems. PMID:17438672

    Celiac disease (CD) is identified by histopathologic changes in the small intestine which normalize during a gluten-free diet. The histopathologic assessment of duodenal biopsies is usually routine but can be difficult. This study investigated gene expression profiling as a diagnostic tool. A total of 109 genes were selected to reflect alterations in crypt-villi architecture, inflammatory response, and intestinal permeability and were examined for differential expression in normal mucosa compared with CD mucosa in pediatric patients. Biopsies were classified using discriminant analysis of gene expression. Fifty genes were differentially expressed, of which eight (APOC3, CYP3A4, OCLN, MAD2L1, MKI67, CXCL11, IL17A, and CTLA4) discriminated normal mucosa from CD mucosa without classification errors using leave-one-out cross-validation (n = 39) and identified the degree of mucosal damage. Validation using an independent set of biopsies (n = 27) resulted in four discrepant cases. Biopsies from two of these cases showed a patchy distribution of lesions, indicating that discriminant analysis based on single biopsies failed to identify CD mucosa. In the other two cases, serology support class according to discriminant analysis and histologic specimens were judged suboptimal but assessable. Gene expression profiling shows promise as a diagnostic tool and for follow-up of CD, but further evaluation is needed. PMID:21378598

    Celiac disease (CD) is an immune-mediated enteropathy that develops in genetically susceptible individuals following exposure to dietary gluten. Severe changes at the intestinal mucosa observed in untreated CD patients are linked to changes in the level and in the pattern of expression of different genes. Fully differentiated epithelial cells express two isoforms of fatty acid binding proteins (FABPs): intestinal and liver, IFABP and LFABP, respectively. These proteins bind and transport long chain fatty acids and also have other important biological roles in signaling pathways, particularly those related to PPARγ and inflammatory processes. Herein, we analyze the serum levels of IFABP and characterize the expression of both FABPs at protein and mRNA level in small intestinal mucosa in severe enteropathy and normal tissue. As a result, we observed higher levels of circulating IFABP in untreated CD patients compared with controls and patients on gluten-free diet. In duodenal mucosa a differential FABPs expression pattern was observed with a reduction in mRNA levels compared to controls explained by the epithelium loss in severe enteropathy. In conclusion, we report changes in FABPs' expression pattern in severe enteropathy. Consequently, there might be alterations in lipid metabolism and the inflammatory process in the small intestinal mucosa. PMID:26346822

    The diagnosis of irritable bowel syndrome (IBS) is based on symptom assessment such as the Rome III criteria. It is sometimes difficult to clinically distinguish IBS from adult-onset celiac disease (CD). Individuals with CD presenting with relatively vague abdominal symptoms are at risk of been dismissed as having IBS. This study aimed to investigate the prevalence of patients with CD among those that fulfill the Rome III criteria for IBS from among patients referred to the gastroenterology section of our hospital over the last 5 years. The study included a total of 968 patients with an average age of 32 years (range 18-59 years). Females constituted 95% of all patients. Duodenal biopsies were obtained during standard gastroscopy. Sections from these biopsies were stained with haematoxylin and eosin and immunostained for human leucocytes CD45 using the avidin-biotin complex (ABC) method. The sections were then histopathologically examined. Four patients had CD: one with Marsh type 3b, and 3 with Marsh type 1. All four of these patients were positive for tissue transglutminase antibodies (anti-t-TG) IgA and were females aged 24, 20, 36 and 38 years. These 4 patients fulfilled the Rome III criteria for the sub-type IBS-diarrhea. This amounts to a prevalence of 0.4% of CD in IBS patients. The present findings support the notion that IBS patients should be routinely examined for CD. This applies to all subtypes of IBS. PMID:21468583

    Celiac disease (CD) is a complex autoimmune disorder in genetically predisposed individuals of all age groups triggered by the ingestion of food containing gluten. A reliable diagnosis is of high interest in view of embarking on a strict gluten-free diet, which is the CD treatment modality of first choice. The gold standard for diagnosis of CD is currently based on a histological confirmation of serology, using biopsies performed during upper endoscopy. Computer aided decision support is an emerging option in medicine and endoscopy in particular. Such systems could potentially save costs and manpower while simultaneously increasing the safety of the procedure. Research focused on computer-assisted systems in the context of automated diagnosis of CD has started in 2008. Since then, over 40 publications on the topic have appeared. In this context, data from classical flexible endoscopy as well as wireless capsule endoscopy (WCE) and confocal laser endomicrosopy (CLE) has been used. In this survey paper, we try to give a comprehensive overview of the research focused on computer-assisted diagnosis of CD. PMID:25770906

    Idiopathic pulmonary hemosiderosis (IPH) is a rare cause of recurrent diffuse alveolar hemorrhage (DAH) with no specific treatment. Herein, we discuss a case of hemoptysis, who had IPH and other rare associations. A 19-year-old man presented with recurrent hemoptysis, generalized weakness and progressive dyspnea for 3 years. Earlier, he was diagnosed with anemia and was treated with blood transfusions and hematinics. On examination he had pallor, tachycardia and was underweight. Investigations revealed low level of hemoglobin (7.8 g/dl) and iron deficiency. An electrocardiography (ECG) showed sinus tachycardia, interventricular conduction delay and T-wave inversion. Echocardiography revealed dilated cardiomyopathy with left ventricular dysfunction. Computed tomography of the chest demonstrated bilateral diffuse ground glass opacity suggestive of pulmonary hemorrhage. Pulmonary function tests showed restrictive pattern with increased carbon monoxide diffusion. Bronchoalveolar lavage and transbronchial lung biopsy showed hemosiderin-laden macrophages. Patient could recall recurrent episodes of diarrhea in childhood. Serum antitissue transglutamase antibodies were raised (291.66 IU/ml, normal <30 IU/ml). Duodenal biopsy showed subtotal villous atrophy consistent with celiac disease. He was started on gluten-free diet, beta blockers and diuretics. After two years of treatment, he has been showing consistent improvement. Screening for CD is important in patients with IPH. Cardiomyopathy forms rare third association. All three show improvement with gluten-free diet. PMID:25624603

    Background. There is limited research investigating the composition of the gastrointestinal microbiota in individuals with celiac disease (CoeD) reporting only partial symptom improvement despite adherence to a strict gluten-free diet (GFD). The aim of this research was to determine if the gastrointestinal microbiota could be altered by probiotic bacteria and provide a potential new therapy for this subgroup. Methods. A multicentre RCT was conducted between January and August 2011 in Australia. Participants included 45 people with CoeD reporting only partial symptom improvement despite adherence to a strict GFD for a minimum of 12 months. Participants took 5 g of VSL#™ probiotic formulation (n = 23) or 5 g placebo (n = 22) orally twice daily for 12 weeks. The main outcome measured was the efficacy of the probiotic formula in altering faecal microbiota counts between baseline and week 12. Safety was determined by safety blood and monitoring adverse events. Results. SPSS™ multivariate repeated measures analysis (95th confidence level) revealed no statistically significant changes between the groups in the faecal microbiota counts or blood safety measures over the course of the study. Conclusion. The probiotic formula when taken orally over the 12-week period did not significantly alter the microbiota measured in this population. The trial was registered with Australian and New Zealand Clinical Trials Register ACTRN12610000630011. PMID:27525027

    Background The role of gluten as a trigger of symptoms in non-coeliac gluten sensitivity has been questioned. Aim To demonstrate that gluten is the trigger of symptoms in a subgroup of patients fulfilling the diagnostic criteria for non-coeliac gluten sensitivity (NCGS), which presented with lymphocytic enteritis, positive celiac genetics and negative celiac serology. Methods Double-blind randomized clinical trial of gluten vs placebo rechallenge. Inclusion criteria: >18 years of age, HLA-DQ2/8+, negative coeliac serology and gluten-dependent lymphocytic enteritis, and GI symptoms, with clinical and histological remission at inclusion. Eighteen patients were randomised: 11 gluten (20 g/day) and 7 placebo. Clinical symptoms, quality of life (GIQLI), and presence of gamma/delta+ cells and transglutaminase deposits were evaluated. Results 91% of patients had clinical relapse during gluten challenge versus 28.5% after placebo (p = 0.01). Clinical scores and GIQLI worsened after gluten but not after placebo (p<0.01). The presence of coeliac tissue markers at baseline biopsy on a gluten-free diet allowed classifying 9 out of the 18 (50%) patients as having probable ‘coeliac lite’ disease. Conclusion This proof-of-concept study indicates that gluten is the trigger of symptoms in a subgroup of patients fulfilling the diagnostic criteria for NCGS. They were characterized by positive celiac genetics, lymphocytic enteritis, and clinical and histological remission after a gluten-free diet.

    Motivated by the necessity of new and efficient methods for dietary gluten control of celiac patients, we have developed a simple and highly sensitive SPR biosensor for the detection of gluten peptides in urine. The sensing methodology enables rapid and label-free quantification of the gluten immunogenic peptides (GIP) by using G12 mAb. The overall performance of the biosensor has been in-depth optimized and evaluated in terms of sensitivity, selectivity and reproducibility, reaching a limit of detection of 0.33 ng mL(-1). Besides, the robustness and stability of the methodology permit the continuous use of the biosensor for more than 100 cycles with excellent repeatability. Special efforts have been focused on preventing and minimizing possible interferences coming from urine matrix enabling a direct analysis in this fluid without requiring extraction or purification procedures. Our SPR biosensor has proven to detect and identify gluten consumption by evaluating urine samples from healthy and celiac individuals with different dietary gluten conditions. This novel biosensor methodology represents a novel approach to quantify the digested gluten peptides in human urine with outstanding sensitivity in a rapid and non-invasive manner. Our technique should be considered as a promising opportunity to develop Point-of-Care (POC) devices for an efficient, simple and accurate gluten free diet (GFD) monitoring as well as therapy follow-up of celiac disease patients.

    Sensibility to gluten is a condition with high immunological reaction against gluten proteins from wheat, barley, rye and oats in individuals genetically susceptible. Celiac disease is its most frequent expression with various forms of clinical presentation. The treatment consists in gluten free diet. Although the biopsy of proximal small bowel is necessary, the importance of serological tests is increasing in the screening, diagnosis and monitoring of gluten free diet in celiac patients. The aim of this study was to investigate the presence of antiendomysium (EmA-IgA) and anti-reticulin (ARA-IgA) antibodies in 56 celiac patients (17 at diagnosis, 24 adherent to the diet and 15 with transgression to the diet). The antibodies were detected by indirect immunofluorescence, using human umbilical cord as substrate for the EmA-IgA and rat liver and kidney for the ARA-IgA. In the patients at diagnosis and in the group with transgression to the diet the total positivity was 100% for EmA-IgA and 59.4% for ARA-IgA. Antibodies were not detected in gluten-free diet patients. Among the 32 positive patients, the concordance of both tests was of 59.4% (19/32), being 40.6% (13/32) negative to ARA-IgA and positive to EmA-IgA. No patient was positive for ARA-IgA and negative for EmA-IgA. Thus, the sensitivity for EmA-IgA was of 100% and 59.4% for ARA-IgA. The association of the two tests did not improve the positivity in the samples. In conclusion, EmA-IgA can be considered the best serological test for diagnosis and follow up of celiac patients, because it presents high predictive value, high specificity and sensibility and is not expensive if using human umbilical cord as substrate.

    Celiac disease (CD) is frequently associated with other autoimmune diseases such as Type 1 diabetes mellitus, autoimmune thyroiditis (AT), and Addison's disease. The frequency of these associations varies with the populations studied. We conducted this study to ascertain the prevalence of CD in patients with AT from Sardinia, an area with a very high prevalence of CD. To this aim, 297 consecutive patients with AT (as defined by elevated antithyroid antibody levels and a positive ultrasound scan) were studied. Immunoglobulin A and G-class antigliadin antibodies were assayed in serum; if either or both were positive, antiendomysium antibodies were determined. If two markers were positive, serum ferritin, folate, and vitamin B12 levels were measured and jejunal biopsy was suggested. Thirteen out of the 14 patients who showed at least two positive markers consented to jejunal biopsy and all of them showed histological features of CD. The prevalence of CD in AT patients was 4-fold greater than that observed in the general population (4.37 vs 1.06%, p<0.0001). Ferritin was low in 6 and vitamin B12 in 2 out of 13 patients; serum folates were normal in all patients. Molecular typing of HLA class II alleles showed an increased frequency of the extended haplotype DRB1*0301/DQA1*0501/DQB1*0201. None of our patients had a history of gastrointestinal symptoms. We confirm the increased prevalence of silent CD in patients with AT. Patients with AT ought to be regarded as a high-risk group for CD and should be screened routinely for it; if negative, screening tests should be repeated at regular intervals. PMID:11407647

    There are 10 things that all gastroenterologists should know about celiac disease (CD). (1) The immunoglobulin A tissue transglutaminase is the single best serologic test to use for the detection of CD. (2) CD can be recognized endoscopically, and water immersion enhances villi detection, although a normal endoscopic appearance does not preclude the diagnosis. (3) It is recommended that 4 biopsies be taken from the second part of the duodenum and 2 bulb biopsies be taken at the 9 o'clock and 12 o'clock positions to maximize the sensitivity for histologic confirmation of CD. (4) Consider serologic testing of first-degree relatives, patients with type 1 diabetes mellitus, Down's, Turner's, and Williams' syndromes, as well as those with premature osteoporosis, iron deficiency, abnormal liver biochemistries, and other manifestations of CD. (5) Patients already on a prolonged gluten-free diet (GFD) should be tested for the presence of HLA DQ2 or DQ8, thereby avoiding the need for further evaluation of CD in non-allelic carriers. (6) The basic treatment of CD is a strict, lifelong GFD, enabled by an expert dietitian. (7) Newly diagnosed adults with CD should be assessed for micronutrient deficiencies (iron, B12, folate, zinc, copper), fat soluble vitamin deficiencies (vitamin D), and bone densitometry. (8) All patients diagnosed with CD should have clinical follow-up to ensure response and adherence to a GFD. (9) In those with persistent or relapsing symptoms, the robustness of the original diagnosis should be reviewed, gluten exposure sought, and a systematic evaluation for alternative and associated diseases performed. (10) Evaluate those with refractory disease for malignant transformation. PMID:25051511

    Celiac disease is a common small intestinal inflammatory condition induced by wheat gluten and related proteins from rye and barley. Left untreated, the clinical presentation of CD can include failure to thrive, malnutrition, and distension in juveniles. The disease can additionally lead to vitamin deficiencies, anemia, and osteoporosis. Therefore, CD potentially negatively affected fitness in past populations utilizing wheat, barley, and rye. Previous analyses of CD risk variants have uncovered evidence for positive selection on some of these loci. These studies also suggest the possibility that risk for common autoimmune conditions such as CD may be the result of positive selection on immune related loci in the genome to fight infection. Under this evolutionary scenario, disease phenotypes may be a trade-off from positive selection on immunity. If this hypothesis is generally true, we can expect to find a signal of natural selection when we survey across the network of loci known to influence CD risk. This study examines the non-HLA autosomal network of gene loci associated with CD risk in Europe. We reject the null hypothesis of neutrality on this network of CD risk loci. Additionally, we can localize evidence of selection in time and space by adding information from the genome of the Tyrolean Iceman. While we can show significant differentiation between continental regions across the CD network, the pattern of evidence is not consistent with primarily recent (Holocene) selection across this network in Europe. Further localization of ancient selection on this network may illuminate the ecological pressures acting on the immune system during this critically interesting phase of our evolution. PMID:23936230

    OBJECTIVES Immunogenic gluten proteins implicated in celiac disease (CD) largely resist degradation by human digestive enzymes. Here we pursued the isolation of gluten-degrading organisms from human feces, aiming at bacteria that would digest gluten under acidic conditions, as prevails in the stomach. METHODS Bacteria with gluten-degrading activities were isolated using selective gluten agar plates at pH 4.0 and 7.0. Proteins in concentrated bacterial cell sonicates were separated by diethylaminoethanol chromatography. Enzyme activity was monitored with chromogenic substrates and gliadin zymography. Elimination of major immunogenic gluten epitopes was studied with R5 and G12 enzyme-linked immunosorbent assays. RESULTS Gliadin-degrading enzyme activities were observed for 43 fecal isolates, displaying activities in the ~150–200 and <50 kDa regions. The active strains were identified as Pseudomonas aeruginosa. Gliadin degradation in gel was observed from pH 2.0 to 7.0. Liquid chromatography–electrospray ionization–tandem mass spectrometry analysis identified the enzyme as pseudolysin (lasB), a metalloprotease belonging to the thermolysin (M4) family proteases. Its electrophoretic mobility in SDS–polyacrylamide gel electrophoresis and gliadin zymogram gels was similar to that of a commercial lasB preparation, with tendency of oligomerization. Pseudolysin eliminated epitopes recognized by the R5 antibody, while those detected by the G12 antibody remained intact, despite destruction of the nearby major T-cell epitope QPQLPY. CONCLUSIONS Pseudolysin was identified as an enzyme cleaving gluten effectively at extremely low as well as near-neutral pH values. The potential to degrade gluten during gastric transport opens possibilities for its application as a novel therapeutic agent for the treatment of CD. PMID:25895519

The most significant non-HLA signal mapped to the intronic region of 70 kb in the LPP gene. Our aim was to fine map and identify possible functional
