Celiac disease associated with autoimmune myocarditis.

BACKGROUND: Both celiac disease (CD) and myocarditis can be associated with systemic autoimmune disorders; however, the coexistence of the 2 entities has never been investigated, although its identification may have a clinical impact. METHODS AND RESULTS: We screened the serum of 187 consecutive patients with myocarditis (118 males and 69 females, mean age 41.7+/-14.3 years) for the presence of cardiac autoantibodies, anti-tissue transglutaminase (IgA-tTG), and anti-endomysial antibodies (AEAs). IgA-tTG-positive and AEA-positive patients underwent duodenal endoscopy and biopsy and HLA analysis. Thirteen of the 187 patients were positive for IgA-tTG, and 9 (4.4%) of them were positive for AEA. These 9 patients had iron-deficient anemia and exhibited duodenal endoscopic and histological evidence of CD. CD was observed in 1 (0.3%) of 306 normal controls (P<0.003). In CD patients, myocarditis was associated with heart failure in 5 patients and with ventricular arrhythmias (Lown class III-IVa) in 4 patients. From histological examination, a lymphocytic infiltrate was determined to be present in 8 patients, and giant cell myocarditis was found in 1 patient; circulating cardiac autoantibodies were positive and myocardial viral genomes were negative in all patients. HLA of the patients with CD and myocarditis was DQ2-DR3 in 8 patients and DQ2-DR5(11)/DR7 in 1 patient. The 5 patients with myocarditis and heart failure received immunosuppression and a gluten-free diet, which elicited recovery of cardiac volumes and function. The 4 patients with arrhythmia, after being put on a gluten-free diet alone, showed improvement in the arrhythmia (Lown class I). CONCLUSIONS: A common autoimmune process toward antigenic components of the myocardium and small bowel can be found in >4% of the patients with myocarditis. In these patients, immunosuppression and a gluten-free diet can be effective therapeutic options.

Occipital lobe seizures related to clinically asymptomatic celiac disease in adulthood.

We report the electroclinical ictal findings of four epileptic patients with clinically asymptomatic celiac disease (CD). Celiac disease diagnosis was suspected by past history and/or computed tomography (CT) findings in all patients and confirmed by laboratory tests and jejunal biopsy. All patients had paroxysmal visual manifestations and ictal EEG discharges arising from the occipital lobe. Epilepsy evolution was favorable in two patients and severe in 2, regardless of CT evidence of occipital corticosubcortical calcifications in 2 patients. Occipital lobe seizures may be characteristic of the epilepsy related to CD, and epileptic patients with these seizures of unknown etiology should be carefully investigated for malabsorption. If past history and/or laboratory tests suggest gastrointestinal (GI) dysfunction they should also undergo small intestinal biopsy even if they do not have GI tract symptoms.

Serum immunoglobulin A from patients with celiac disease inhibits human T84 intestinal crypt epithelial cell differentiation.

BACKGROUND & AIMS: Celiac disease is characterized by disturbed jejunal crypt-villus axis biology with immunoglobulin (Ig) A deposits underlining the epithelium. The aim of this study was to test whether celiac disease serum IgA (reticulin/endomysial autoantibodies) interferes with the mesenchymal-epithelial cell cross-talk. METHODS: Differentiation of T84 epithelial cells was induced with IMR-90 fibroblasts or transforming growth factor beta in three-dimensional collagen gel cultures. The effects of purified celiac IgA and monoclonal tissue transglutaminase antibodies (CUB7402) were studied by adding the antibodies to the cocultures. RESULTS: Active celiac disease IgA, reactive for tissue transglutaminase, significantly inhibited T84 epithelial cell differentiation (P < 0.001) and increased epithelial cell proliferation (P = 0.024). Similar effects were obtained with antibodies against tissue transglutaminase. CONCLUSIONS: Celiac disease-associated IgA class antibodies disturb transforming growth factor beta-mediated fibroblast-epithelial cell cross-talk in this in vitro crypt-villus axis model. This primary finding indicates that celiac disease-specific autoantibodies may also contribute to the formation of the gluten-triggered jejunal mucosal lesion in celiac disease.

Increased prevalence of autoantibodies in celiac disease.

Several features suggest an immune mechanism operates in celiac disease. Information on the autoantibody repertoire in this condition is lacking. The purpose of the study was to investigate the reactivity of celiac patients sera to various autoantigens widely distributed in the human intestine. Seventy children, celiacs and controls, were evaluated for serum autoantibodies using ELISA and immunofluorescence. Celiac patients had increased prevalence of serum anti-single-stranded DNA (14%), anti-double-stranded DNA (23%), anti-cardiolipin (14%), and anti-endomysial autoantibodies (63%). The relevance of this finding on the extraintestinal manifestations of celiac disease or the coexistence of autoimmune conditions and celiac disease remains to be determined.

Celiac disease and human leukocyte antigen genotype: accuracy of diagnosis in self-diagnosed individuals, dosage effect, and sibling risk.

BACKGROUND: Celiac disease is an autoimmune disorder of the small intestine characterized by intolerance to gluten. Traditionally, diagnosis is made by intestinal biopsy. Testing for immunoglobulin (Ig) A endomysial antibodies in the serum also is used for diagnosis. Biopsy and serology revert to normal with adherence to a gluten-free diet. Often, after an index case is diagnosed, siblings with symptoms adhere to a gluten-free diet without biopsy or serologic confirmation. More than 90% of patients with celiac disease have the human leukocyte antigen (HLA) DQA1*0501-DQB1*0201 genotype. Non-HLA genes also have been implicated. METHODS: One hundred ninety-five individuals with confirmed or suspected celiac disease were identified in 73 families affected by the disease. IgA endomysial antibody testing was performed for all symptomatic family members who did not have biopsy-confirmed diagnoses. DNA samples were genotyped at D6S276 and the HLA class II loci DQA and DQB. RESULTS: At the time sampling was begun in families, 88 of 177 (49.7%) individuals were self-diagnosed and adhering to a gluten-free diet. Ninety percent (91/101) of confirmed cases (biopsy or serology) had at least 1 copy of the DQA1*0501-DQB1*0201 genotype, whereas only 67% (46/69) of cases self-diagnosed (adherence to gluten-free diet without confirmation) had at least 1 copy. Of confirmed cases, 61% carried two copies of DQB*0201. It is estimated that the HLA association and other unlinked genes contribute approximately equally to the sibling risk of celiac disease. CONCLUSIONS: A dosage effect of DQB1*0201 may be associated with an increased risk of celiac disease. Self-diagnosis of celiac disease is as common as confirmed diagnosis in families in the United States. Diagnosis of celiac disease on the basis of clinical response to gluten restriction is inaccurate. With long-term adherence to a gluten-free diet, serologic test results are likely to be negative. Based on HLA genotype, approximately one third of self-diagnosed individuals are unlikely to have celiac disease. However, it is not possible to determine which individuals consuming a gluten-free diet have the disease. Therefore, before starting a gluten-free diet, serologic screening and biopsy confirmation are necessary.

Bone mineral affection in asymptomatic adult patients with celiac disease.

OBJECTIVES: Osteopenia is a well-known complication of overt celiac disease, but whether such defective bone mineralization is present among asymptomatic or silent patients is not known. Our objectives were: 1) to examine bone mineralization of a group of asymptomatic celiac patients; 2) to compare these results with those of symptomatic patients. METHODS: Bone mineral density of the spine and total skeleton by dual energy x-ray absorptiometry and serum parameters of mineral metabolism of eight recently diagnosed asymptomatic patients with celiac disease were studied. Results were compared with those obtained in 20 untreated symptomatic celiacs, 14 patients treated with gluten-free diet for a mean time of 15 yr, and 153 healthy adult subjects, matched by sex and age. RESULTS: Four and five out of eight asymptomatic patients presented with reduced mineralization of the spine and the total skeleton, respectively (> 1 SD below normal values for sex and age). Two patients presented with severe osteopenia of the spine, and the other three presented with severe osteopenia of the whole skeleton (> 2 SD below mean normal values). Osteopenia at plane bone level (total skeleton) was significantly lower when compared to healthy controls (p < 0.02). Symptomatic untreated patients had significantly more severe deterioration of bone mineralization than did asymptomatics (p < 0.05) and treated patients (p < 0.05). No difference in bone mineral density was observed between treated patients and asymptomatic celiacs. Serum levels of calcium, alkaline phosphatase, 25-OH vitamin D, and parathormone did not show conclusive abnormalities. CONCLUSIONS: Our findings provide direct evidence that reduced bone mineralization occurs in asymptomatic celiac patients before any other symptom becomes evident. Only early diagnosis and treatment of celiac disease can avoid the deterioration of the bone structure observed in all clinical status of celiac disease.

Celiac disease: a reappraisal.

During the last decade significant changes have occurred in our concepts of celiac disease. As a result of the implementation of sensitive and specific serologic tests, the epidemiology and clinical presentation of affected patients have been radically reconsidered. Extraintestinal manifestations of celiac disease have been radically reconsidered. Extraintestinal manifestations of celiac disease have been increasingly recognized, and the strict association with diseases recognized as autoimmune disorders is well established; celiac disease itself has many aspects of an autoimmune condition. Celiac disease is of interest to clinicians and scientists because it represents a valuable model for the comprehension of diseases in which environmental, genetic, and immunologic factors interplay.

Celiac disease and risk of subsequent type 1 diabetes: a general population cohort study of children and adolescents.

OBJECTIVE: Earlier studies suggest that children with type 1 diabetes are more likely to have a subsequent diagnosis of celiac disease. However, research is sparse on the risk of subsequent type 1 diabetes in individuals with celiac disease. We sought to determine the risk of subsequent type 1 diabetes diagnosed before the age of 20 years in children and adolescents with celiac disease in a national, general population-based cohort. RESEARCH DESIGN AND METHODS: We identified 9,243 children with a diagnosis of celiac disease in the Swedish national inpatient register between 1964 and 2003. We then identified five reference individuals matched at time of diagnosis for age, calendar year, sex, and county (n = 45,680). Only individuals with >1 year of follow-up after study entry (diagnosis of celiac disease) were included in the analyses. RESULTS: Celiac disease was associated with a statistically significantly increased risk of subsequent type 1 diabetes before age 20 years (hazard ratio 2.4 [95% CI 1.9-3.0], P < 0.001). This risk increase was seen regardless of whether celiac disease was first diagnosed between 0 and 2 (2.2 [1.7-2.9], P < 0.001) or 3 and 20 (3.4 [1.9-6.1], P < 0.001) years of age. Individuals with prior celiac disease were also at increased risk of ketoacidosis or diabetic coma before the age of 20 years (2.3 [1.4-3.9], P = 0.001). CONCLUSIONS: Children with celiac disease are at increased risk of subsequent type 1 diabetes. This risk increase is low considering that 95% of individuals with celiac disease are HLA-DQ2 positive.

Celiac disease in a Chilean population carrying Amerindian traits.

BACKGROUND: Although clinical manifestations of celiac disease may change throughout life, clinical, histologic, immunologic, and genetic studies show that there are incomplete forms of this condition, making it difficult to define the disease at a given moment. Because there is no information published in the Latin American-Amerindian population, this study was conducted to assess relations between these parameters in Chileans with celiac disease and their first-degree relatives. METHODS: Sixty-two persons with confirmed celiac disease (mean age, 17.9 +/- 5.1 years; 78.3% females) and 126 relatives (mean age, 27.9 +/- 17.2 years; 65.1% females) were evaluated. Clinical manifestations, antiendomysial antibodies (EMAs), and human leukocyte antigen (HLA) haplotypes were studied in patients. Additionally, jejunal biopsy specimens were assessed (light microscopy) in EMA-positive (EMA+) relatives. RESULTS: Of the patients, 24.1% adhered to a strict gluten-free diet; 26% were oligosymptomatic, and none were malnourished; 45% were EMA+; 13.8% who ingested gluten were EMA-negative (EMA-); one patient consuming a strict gluten-free diet was EMA+. The DQA1*0501 allele was present in the highest frequency (48%, P < 0.0005), whereas combinations of DQ8 were predominant. Of the relatives, 4.8% were EMA+; they had a significantly higher frequency of diarrhea, weight loss, and anorexia (P < 0.03); and all had abnormal histology in biopsy specimens. CONCLUSIONS: After childhood, celiac disease is oligosymptomatic and is often unrecognized by patients. Disease in 13.8% of patients and in 4.8% relatives appeared as incomplete forms of celiac disease. Predominance of DQ8 HLA haplotypes reflects the genetic Spanish-Mapuche heritage of this population.

Risk of celiac disease autoimmunity and timing of gluten introduction in the diet of infants at increased risk of disease.

CONTEXT: While gluten ingestion is responsible for the signs and symptoms of celiac disease, it is not known what factors are associated with initial appearance of the disease. OBJECTIVE: To examine whether the timing of gluten exposure in the infant diet was associated with the development of celiac disease autoimmunity (CDA). DESIGN, SETTING, AND PATIENTS: Prospective observational study conducted in Denver, Colo, from 1994-2004 of 1560 children at increased risk for celiac disease or type 1 diabetes, as defined by possession of either HLA-DR3 or DR4 alleles, or having a first-degree relative with type 1 diabetes. The mean follow-up was 4.8 years. MAIN OUTCOME MEASURE: Risk of CDA defined as being positive for tissue transglutaminase (tTG) autoantibody on 2 or more consecutive visits or being positive for tTG once and having a positive small bowel biopsy for celiac disease, by timing of introduction of gluten-containing foods into the diet. RESULTS: Fifty-one children developed CDA. Findings adjusted for HLA-DR3 status indicated that children exposed to foods containing wheat, barley, or rye (gluten-containing foods) in the first 3 months of life (3 [6%] CDA positive vs 40 [3%] CDA negative) had a 5-fold increased risk of CDA compared with children exposed to gluten-containing foods at 4 to 6 months (12 [23%] CDA positive vs 574 [38%] CDA negative) (hazard ratio [HR], 5.17; 95% confidence interval [CI], 1.44-18.57). Children not exposed to gluten until the seventh month or later (36 [71%] CDA positive vs 895 [59%] CDA negative) had a marginally increased risk of CDA compared with those exposed at 4 to 6 months (HR, 1.87; 95% CI, 0.97-3.60). After restricting our case group to only the 25 CDA-positive children who had biopsy-diagnosed celiac disease, initial exposure to wheat, barley, or rye in the first 3 months (3 [12%] CDA positive vs 40 [3%] CDA negative) or in the seventh month or later (19 [76%] CDA positive vs 912 [59%] CDA negative) significantly increased risk of CDA compared with exposure at 4 to 6 months (3 [12%] CDA positive vs 583 [38%] CDA negative) (HR, 22.97; 95% CI, 4.55-115.93; P = .001; and HR, 3.98; 95% CI, 1.18-13.46; P = .04, respectively). CONCLUSION: Timing of introduction of gluten into the infant diet is associated with the appearance of CDA in children at increased risk for the disease.

[Pathogenetic mechanisms of anemia in children with celiac disease].

Pathogenetic mechanisms of anemia development were studied in children with celiac disease to develop guiding rules for administration of complex therapy. It has been found out that celiac disease in children is accompanied by a high incidence of grave forms of anemia that adversely affect the course of the underlying condition. In anemic children with celiac disease, manifest pathophysiologic and pathobiochemical alterations in the hemoglobin and iron status are most common, with anemia of hyperregeneratory character being more prevalent. In children with celiac disease, the complex of therapy of anemia that do not respond to the instituted treatment options should be supplemented with protein preparations or activators of protein metabolism and with medicinal agents capable of correcting intestinal microflora.

Interleukin 15: a key to disrupted intraepithelial lymphocyte homeostasis and lymphomagenesis in celiac disease.

BACKGROUND & AIMS: The mechanism of intraepithelial lymphocyte hyperplasia, a hallmark of celiac disease, is unknown. We have investigated the role of epithelium-derived interleukin (IL)-15 in the alterations of epithelial homeostasis in refractory celiac sprue, a privileged situation to study the first step of lymphoid transformation and the contribution of intraepithelial lymphocytes to villous atrophy in celiac disease. METHODS: IL-15 expression was assessed in biopsy specimens and isolated enterocytes by combining immunohistochemistry, flow cytometry, and real-time quantitative polymerase chain reaction. The ability of IL-15 to induce growth and survival of clonal intraepithelial lymphocytes lacking surface CD3 and to induce their cytotoxicity and secretion of interferon gamma was tested using soluble IL-15 and coculture in the presence of epithelial cell lines expressing membrane IL-15. RESULTS: IL-15 was massively overexpressed not only in lamina propria but also in the intestinal epithelium of patients with active celiac disease and refractory celiac sprue. IL-15 was not secreted but delivered at the surface of enterocytes. IL-15 specifically induced the expansion and survival of the clonal abnormal intraepithelial lymphocytes that characterize refractory celiac sprue and triggered their secretion of interferon gamma and their cytotoxicity against intestinal epithelial cells. Comparable activating signals could be delivered by IL-15 expressed at the membrane of the T84 enterocyte cell line. CONCLUSIONS: These data provide strong evidence that uncontrolled overexpression of IL-15 in refractory celiac sprue perpetuates epithelial damage and promotes the emergence of T-cell clonal proliferations. Blocking IL-15 might prove useful to treat this severe complication of celiac disease.

Celiac disease and selective immunoglobulin A deficiency.

Selective IgA deficiency was observed in 12 of 688 (1.7%) patients with celiac disease who were clinically undistinguishable from patients with celiac disease with normal IgA levels. This high prevalence of IgA deficiency in patients with celiac disease makes serum IgA assay advisable when screening for celiac disease is performed by measurement of antigliadin antibodies or anti-IgA endomysium antibodies. Similarly, subjects with IgA deficiency should be considered at risk of celiac disease.

Dermatomyositis associated with celiac disease: response to a gluten-free diet.

The association between dermatomyositis and celiac disease in children has been well documented. In the adult population, however, the association has not been clearly established. A rare case of concomitant dermatomyositis and celiac disease in a 40-year-old woman is presented. After having been diagnosed with dermatomyositis and iron deficiency anemia, this patient was referred to the gastroenterology clinic to exclude a gastrointestinal malignancy. Blood tests revealed various vitamin deficiencies consistent with malabsorption. The results of gastroscopy with duodenal biopsy were consistent with celiac disease. After she was put on a strict gluten-free diet, both nutritional deficiencies and the dermatomyositis resolved. The patient's human leukocyte antigen haplotype study was positive for DR3 and DQ2, which have been shown to be associated with both juvenile dermatomyositis and celiac disease. It is suggested that patients with newly diagnosed dermatomyositis be investigated for concomitant celiac disease even in the absence of gastrointestinal symptoms.

Diagnostic duodenal bulb biopsy in celiac disease.

BACKGROUND AND STUDY AIMS: Duodenal or jejunal biopsies are needed to establish the diagnosis of celiac disease. It is widely advocated that these biopsies be taken from the distal duodenum. PATIENTS AND METHODS: After finding two index cases with diagnostic biopsies taken from the duodenal bulb, we retrospectively analyzed biopsies from the descending duodenum and the duodenal bulb of 51 patients with suspected or diagnosed celiac disease. The diagnosis of celiac disease and classification of the histological changes were performed by one pathologist. RESULTS: In the two index cases the diagnosis of celiac disease could only be established by taking the biopsies from the duodenal bulb, and not from the descending duodenum. In the retrospective analysis the number of intraepithelial lymphocytes was on average higher, but not significantly, in the descending part of the duodenum. CONCLUSIONS: Most patients with celiac disease show similar mucosal changes in biopsies taken from the descending part of the duodenum and from the duodenal bulb. But in patients who have already been on a gluten-free diet in childhood and later abandoned their diet, an additional duodenal bulb biopsy should be done.

Duodenal histology in patients with celiac disease after treatment with a gluten-free diet.

BACKGROUND: The diagnosis of celiac disease requires characteristic histopathologic changes in an intestinal biopsy with clinical improvement in response to a gluten-free diet. Endoscopy with procurement of biopsy specimens is often performed to document response to the diet, but there are little data on the appearance of treated celiac disease. This study examined the endoscopic and histopathologic appearance of the duodenum of patients with celiac disease whose diet was gluten-free. METHODS: A cohort of 39 adult patients (mean age 52 years, range 20-74 years) with biopsy-proven celiac disease was retrospectively reviewed. All had responded clinically to a gluten-free diet that they had maintained for a mean of 8.5 years (range 1-45 years). The endoscopic and histopathologic appearances of the duodenal mucosa were reviewed. Blinded review of the diagnostic (initial) and post-treatment biopsy specimens was also performed to assess response of individual patients to the diet. RESULTS: The endoscopic appearance was normal in 23%, reduced duodenal folds were present in 46%, scalloping of folds in 33%, mucosal fissures in 44%, and nodularity in 33%. There was more than 1 abnormality present in 46%. Histology was normal in only 21%. The remainder had villous atrophy (69% partial, 10% total). Paired (diagnostic and follow-up) biopsy specimens were reviewed blindly for 12 patients. The mean (SD) intraepithelial lymphocyte count fell from 61 (22) to 38 (17) (normal <30 per 100 epithelial cells) and the crypt-to-villous ratio improved although it did not normalize. CONCLUSIONS: Despite a good clinical response, abnormal endoscopic and histopathologic appearances persist in the majority of patients with celiac disease treated with a gluten-free diet.

The gluten-free diet: a nutritional risk factor for adolescents with celiac disease?

BACKGROUND: The gluten-free diet is the standard therapy for patients affected by celiac disease, although compliance with the diet is not optimal in adolescents or adults. Moreover, the gluten-free diet may induce nutritional imbalances. METHODS: Alimentary habits and diet composition were examined in 47 adolescents with celiac disease and 47 healthy aged-matched control subjects. All subjects compiled a 3-day alimentary record that allowed determination of their energy intakes: the macronutrient composition of their diets; and their iron, calcium, and fiber intakes. To evaluate compliance with the gluten-free diet, immunoglobulin A antigliadin and antiendomysium antibodies were assessed in all with celiac disease. RESULTS: The analysis of the records and the results of antibody levels showed that 25 subjects strictly followed dietetic prescriptions (group 1A), whereas 22 patients consumed gluten-containing food (group 1B). Those with celiac disease and control subjects (group 2) consumed a normocaloric diet. Lipid and protein consumption was high, however, and the consumption of carbohydrates low. Moreover, dietary levels of calcium, fiber, and especially in girls, iron, were low. These nutritional imbalances were significantly more evident in group 1A than in group 1B, as a consequence of poor alimentary choices. Moreover, in group 1A overweight and obesity were more frequent (72%) than in group 1B (51%) and in the control subjects (47%). CONCLUSIONS: In people with celiac disease, adherence to a strict gluten-free diet worsens the already nutritionally unbalanced diet of adolescents, increasing elevated protein and lipid consumption. In the follow-up of patients with celiac disease, considerable effort has yet to be made to improve compliance with a gluten-free diet, and especially to control the nutritional balance of the diet in compliant patients.

Early changes of body composition in asymptomatic celiac disease patients.

BACKGROUND/AIM: This is a study of patients with asymptomatic celiac disease. The aims of this study were: 1) To evaluate the nutritional status of asymptomatic patients with newly diagnosed celiac disease, and 2) to compare these findings with those of untreated/symptomatic and treated patients. MATERIAL: We examined 41 patients with celiac disease divided into three groups: a) 8 asymptomatic (diagnosed in a study of first-degree relatives of probands), b) 20 untreated/symptomatic patients, and c) 13 treated patients. Nutrition of patients from groups A and B was assessed at the time of diagnosis. METHODS: Nutritional status was evaluated by: 1) body composition (fat and lean mass) by dual energy x-ray absorptiometry (DEXA), and 2) anthropometric measurements. RESULTS: Compared with sex and age matched controls (n = 153), asymptomatic patients presented a moderate but significant reduction of the fat compartment (-29%; p < 0.001), but not of the lean-tissue mass (p = NS). Untreated/symptomatic patients showed a more severe depletion of fat (-46%; p < 0.001) and lean mass (-9.0%; p < 0.05) compared with healthy controls. Although fat mass of treated patients was significantly reduced with respect to controls (-24%; p < 0.003), lean mass was not affected. The anthropometric measurements of fat showed a significant correlation with the evaluation by DEXA (multiple regression analysis r = 0.918). CONCLUSION: Asymptomatic patients in our study with an unequivocal diagnosis of celiac disease established by mucosal biopsy exhibited a modified body composition.
