Tissue transglutaminase antibody levels predict IgA deficiency. Arch Dis Child. 1999-02-01 · Objective: Tissue transglutaminase (tTG) is the main autoantigen recognized by endomysial antibodies. The aim of this study was to assess sensitivity, specificity, and predictive value of IgA and IgG antibodies to tTG in the diagnosis of celiac disease compared with endomysial antibodies.

The Tissue Transglutaminase Antibodies (tTG-IgA) test will be positive in about 98% of patients with celiac disease who are on a gluten-containing diet. The test’s sensitivity measures how correctly it identifies those with the disease. The same test will come back negative in about 95% of healthy people without celiac disease.

The high sensitivity and specificity of the anti-transglutaminase IgA autoantibody assays, respectively 96-98% and 93-95%, 12 associated with the objectivity and full automation offered by the test, have meant that in recent years anti-t-TG IgA testing has superseded older serological tests for CD. 13 Testing for anti-endomysial IgA antibodies (EMA) nevertheless plays an important role in The role of immunoglobulin A (IgA) anti-tissue transglutaminase antibodies (IgA-tTG) as predictors of untreated celiac disease (CoD) is well documented, and the presence and levels of these antibodies are most accurately monitored with native or recombinant human antigens. However, IgA-deficient CoD patients are not identified by IgA serology, and conflicting results concerning the diagnostic Elevation of IgG antibodies against tissue transglutaminase as a diagnostic tool for coeliac disease in selective IgA deficiency.

For individuals with moderately to strongly positive results, a diagnosis of celiac disease is possible and the patient should undergo a biopsy to confirm the diagnosis. Diagnostic accuracy of IgA anti-tissue transglutaminase antibody assays in celiac disease patients with selective IgA deficiency Clinical studies have estimated a 10- to 20-fold increased risk for celiac disease (CD) in patients with selective IgA deficiency (SIgAD). Antibodies against transglutaminase virtually never occur in healthy individuals or in patients with other intestinal diseases, whereas in untreated GSE their prevalence is almost 100%. Transglutaminase antibodies are mostly of the immunoglobulin class IgA. Class IgG occurs in low concentrations in 50% of IgA positive sera.

“The most frequently used test is the tTG. Presence of the tissue transglutaminase (tTG) IgA antibody is associated with glutensensitive enteropathies such as celiac disease and dermatitis herpetiformis. tTG IgA antibody concentrations greater than 40 U/mL usually correlate with results of duodenal biopsies consistent with a diagnosis of celiac disease. Se hela listan på rchsd.org Several antibodies may be produced during the course of the disease (anti-transglutaminase, anti-gliadin, anti-endomysium). Among these, anti-transglutaminase levels are considered the most useful.
