BACKGROUND In the diagnosis of celiac disease (CD), serum assays for anti-endomysium (EMA) and anti-transglutaminase (anti-tTG) antibodies have excellent diagnostic accuracy. However, these assays are less sensitive in young pediatric patients. Recently, a new ELISA test using deamidated gliadin peptides (DGP) as antigen has proved to be very sensitive and specific even in pediatric patients. I...

BACKGROUND Duodenal biopsy is required for diagnosis of celiac disease in adults, although some studies have suggested adequate accuracy of serology alone. OBJECTIVE We aimed to assess the correlation between anti-tissue transglutaminase (tTG) titer and pathological findings and to define the specific level of tTG for predicting celiac disease in adults without the need for biopsy sampling. M...

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...

BACKGROUND The detection of anti-transglutaminase IgA (tTG) and anti-endomysial (EMA) is used for screening of celiac disease (CD) with a sensitivity and specificity of 90 and 99% respectively. There is an association between CD and connective tissue diseases (CTD). AIM To report the frequency of IgA tTG and EMA in patients with a definite diagnosis of CTD and inflammatory arthropathies (IA)....

BACKGROUND We aimed to investigate the frequency of celiac disease in children with β-thalassemia major (B-TM) in Shiraz, southern Iran. MATERIALS AND METHODS In this study, the prevalence of celiac disease in children with B-TM was evaluated. Children with B-TM were screened for celiac disease by ant-tissue transglutaminase (anti-tTG) IgA antibody, IgA level and anti-tTG IgG. A total of 1500...

BACKGROUND Assays for IgG antibodies against deamidated gliadin (IgG-anti-dGli) are comparable in performance with tests detecting IgA antibodies against tissue transglutaminase (IgA-anti-tTG) in diagnosing celiac disease (CD). IgA-anti-tTG are absent in IgA deficiency, a condition often associated with CD. In IgA deficiency, IgG-anti-tTG, which have a lower overall diagnostic accuracy, are rou...

OBJECTIVE In children with type 1 diabetes mellitus (T1DM), elevated levels of antitissue transglutaminase (anti-tTG) antibody may spontaneously normalize, despite continued consumption of gluten. We aimed to investigate the prevalence of spontaneous normalization of anti-tTG levels and the existence of factors predictive for this outcome. RESEARCH DESIGN AND METHODS All children referred fro...

background: celiac disease (cd) has been found in up to 10% of the patients presenting with unexplained abnormal liver function tests (lft). as there is no precise data from our country in this regard, we investigated the prevalence of cd in patients presenting with abnormal lft. methods: from 2003 to 2008, we measured iga anti-tissue transglutaminase (t-tg) antibody (with elisa technique) with...

In the last twenty years serology for the diagnosis of coeliac disease has improved substantially. As the result of our serological studies in 1998 we proposed a gentle, low-risk, and cost eff ective algorithm for diagnosing various forms of gluten sensitive enteropathy, using a combination of diff erent antibody determinations, namely IgA Endomysium antibodies (EMA), Tissue-transglutaminase an...

BACKGROUND Celiac disease (CD) is an immune-mediated disorder induced by the ingestion of gluten in genetically susceptible persons. The prevalence of CD in Malaysia is unknown. We aim to determine the seroprevalence of CD antibodies and also investigate the correlation between H. pylori infection and CD in the young and healthy multiracial Malaysian population. METHODS Healthy young adult vo...
