OBJECTIVE To analyze if it is worthwhile to screen Brazilian osteoporotic patients for celiac disease (CD). SUBJECTS AND METHODS One hundred patients with osteoporosis and 97 controls were evaluated for IgA-EmA (IgA anti-endomysial antibodies) by indirect immunofluorescence method and IgG-anti-tTG (tissue transglutaminase) by ELISA assay. Positive patients were invited to have gastrointestina...

INTRODUCTION We report a case of sero-negative celiac disease in Pakistan. CASE PRESENTATION A 20-year-old female presented with papulovesicular rash for 15 years, diarrhea for 8 years, spasms of hands and twitching of face for 4-5 months. She had mild anemia, low vitamin-D3 and serum calcium. On exclusion of other causes of malabsorption, anti-tissue transglutaminase antibodies (immunoglobul...

Celiac disease (CD) is an enteropathy caused by the ingestion of wheat gluten in genetically susceptible individuals. A complete understanding of the pathogenic mechanisms in CD has been hindered because of the lack of adequate in vivo models. In the present study, we explored the events after the intragastric administration of gliadin and of the albumin/globulin fraction from wheat in human le...

Two human erythroleukemia cell lines, HEL and KS62, express transglutaminase activity. The enzyme was identified as a tissue transglutaminase following Chromatographie purification. All-fra/w-retinoic acid (10 MM)stimulated differentiation in HEL cells as judged by a 4-fold increase in hemoglobin content and a reduction in cell proliferation. The transglutaminase activity increased 9-fold. This...

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 endosc...

Celiac disease was previously reported to be frequent among individuals with Williams-Beuren syndrome; however, this suggestion was not investigated further. The present study was conducted to estimate the prevalence of celiac disease in a group of Turkish individuals with Williams-Beuren syndrome (n=33, age range: 1-24 years) by using anti-tissue transglutaminase immunoglobulin (Ig)A and IgG, ...
