BACKGROUND Conflicting data have been published concerning the effect of calcium on binding of autoantibodies to tissue transglutaminase (tTG) in celiac disease (CD). METHODS IgA-tTG and IgG-tTG were measured with radioligand binding assays (RBA) using human recombinant (hr) (35)S-tTG produced in lysate of rabbit reticulocytes and with guinea pig (gp) tTG ELISA in 51 CD children (median: 5.7 ...

Results: Of these patients, 141 (92.8%) had a positive tTG-IgA and 11 (7.2%) had a negative result. Eighty-one (53.3%) did not have an EGD performed due to patient or legal representatives declining. Of the 71 who had a biopsy, the result of the tTG-IgA in 29 (40.8%) was a true positive, 35 (49.3%) a false positive, 2 (2.8%) a true negative, and 5 (7.0%) a false negative. The sensitivity was 85...

Background: Anti-thyroid peroxidase antibody (anti-TPO antibody) is a member of thyroid autoantibodies which are important in inducing and also diagnosing autoimmune thyroid diseases. Thyroid autoimmunity can cause several forms of thyroiditis and abnormal thyroid functions, ranging from hypothyroidism to hyperthyroidism. Objective: To evaluate the relationship between serum levels of anti-TPO ...

BACKGROUND Delay in diagnosis of celiac disease (CD) occurs frequently, although its consequences are mostly not known. One of the presented symptoms in pediatric patients with CD is the short stature. However, far too little attention has been paid to physical features including height of adult patients with CD. This study was undertaken to evaluate whether patients suffering from CD are short...

backgrounds: iron deficiency anemia (ida) is one of the well recognized presentations of celiac disease (cd). according to the lack of data from our population in this regard, we determined the prevalence of cd in patients presenting with ida to see if it is worthwhile to do a precise screening for cd in such patients. methods: this cross-sectional study was conducted on patients referred with ...

Objective: The autoimmune diseases tend to coexist with diabetes mellitus type I (T1DM). The concomitance of these two types of diseases will lead to poor glycemic control beside their own complications. In this study the prevalence of thyroid disorder and celiac disease among T1DM patients in Yazd, Iran was evaluated. Materials and Methods: all the patients diagnosed as T1DM in Yazd younger t...

The role of tissue transglutaminase (tTG) in cancer development remains an important field of study. The aim of the current study was to understand the involvement of tTG in cancer and the inhibitory effect of cantharidinate on the expression of tTG in human colorectal cancer (CRC) using immunohistochemical and PCR analysis. The results showed that the expression of tTG increased in human CRC a...

Tissue transglutaminase (tTG) is a multifunctional enzyme with transglutaminase crosslinking (TGase), GTP binding, and hydrolysis activities that play a role in many different disorders. We identified, characterized, and investigated the function and stability of two alternatively spliced forms of tTG using biochemical, cellular, and molecular biological approaches. Using a human aortic vascula...

Tissue-type transglutaminase (tTG, EC 2.3.2.13) has been implicated in various disease paradigms including neurodegenerative disease. In these studies, tTG induction after traumatic brain injury was studied using a rat cortical impact model. Using western blots, two forms of tTG protein expression were identified--an approximately 79-kDa primary form (tTG-L) and a less abundant approximately 70...
