BACKGROUND Wheat, rye, and barley proteins induce celiac disease, an autoimmune type of gastrointestinal disorder, in genetically susceptible persons. Because the disease may be underdiagnosed, we estimated the prevalence of the disease and tested the hypothesis that assays for serum autoantibodies can be used to detect untreated celiac disease and that(More)
BACKGROUND IgA class serum autoantibodies against type 2 (tissue) transglutaminase (TG2) bind to both intestinal and extraintestinal normal tissue sections in vitro, eliciting endomysial, reticulin, and jejunal antibody reactions. It is not known whether similar binding also occurs in coeliac patients in vivo, and may thereby contribute to disease(More)
BACKGROUND The number of coeliac disease diagnoses has increased in the recent past and according to screening studies, the total prevalence of the disorder is around 1%. AIM To establish whether the increased number of coeliac disease cases reflects a true rise in disease frequency. METHODS The total prevalence of coeliac disease was determined in two(More)
BACKGROUND Some patients with untreated coeliac disease are negative for serum endomysial autoantibodies (EmA) targeted against transglutaminase 2 (TG2). AIMS To evaluate the clinical and histological features of EmA-negative coeliac disease, and to examine whether EmA-equivalent autoantibodies against TG2 can be seen in the small-bowel mucosa when absent(More)
BACKGROUND & AIMS The diagnostic criteria for celiac disease require small-bowel mucosal villous atrophy with crypt hyperplasia (Marsh III). However, mucosal damage develops gradually and patients may evince clinical symptoms before histologic changes appear. Endomysial antibodies are specific in predicting forthcoming villous atrophy. We hypothesized that(More)
OBJECTIVES Cow's milk protein-sensitive enteropathy (CMSE) may persist in children to school age. We sought to define the morphologic and immunohistochemical features of persistent CMSE. STUDY DESIGN We studied 15 children with a definite diagnosis of CMSE on the basis of a blind challenge, 12 children with suspected cases of CMSE, 11 children with celiac(More)
OBJECTIVE Our earlier 5-year follow-up study produced the first evidence to show the long-term safety of oats as part of a coeliac diet. The objective of the present study was to clarify its applicability by analysing local cellular immunological responses after 5 years' consumption of oats by adult coeliac patients. MATERIAL AND METHODS Forty-two coeliac(More)
BACKGROUND & AIMS Tissue transglutaminase has been reported to be the target for endomysial antibodies in celiac disease. We sought to establish whether immunoglobulin (Ig) A class tissue transglutaminase autoantibodies can be considered specific for celiac disease. METHODS Serum samples from 136 patients with untreated celiac disease (diagnosed according(More)
BACKGROUND Reliable markers of early developing coeliac diseases are needed. Coeliac autoantibodies in the serum or Marsh I inflammation may be indicators of subsequent coeliac disease. AIM To investigate whether determination of intestinal transglutaminase 2-targeted autoantibody deposits would detect early developing coeliac disease better than previous(More)
BACKGROUND & AIMS In patients with celiac disease, gluten-induced lesions of the small-bowel mucosa develop gradually. However, it is not clear whether clinical presentation correlates with the degree of mucosal damage based on histology analysis. We investigated whether the degree of mucosal damage to the small bowel correlates with clinical presentation(More)
