Prevalence and levels of antibodies in patients and controls.

Prevalence of antibody positivity and antibody levels for endomysial autoantibodies (EmA), autoantibodies to tissue transglutaminase (anti-tTG) and glycoprotein 2 (anti-GP2) as well as anti-Saccharomyces cerevisiae antibodies (ASCA) in patients with active celiac disease (CD), CD under gluten-free diet (GFD) and 129 controls. Median antibody titers are given in U/mL (anti-GP2, anti-tTG, ASCA) or titer (EmA).a In one patient, EmA-IgA titre was 1:10 (borderline), but the other antibodies were positive and histology showed a Marsh 3c (total villous atrophy).b Fisher’s exact test, CD versus CD under GFDc Fisher’s exact test, CD versus controlsd two-tailed, non-parametric Mann-Whitney test, CD versus CD under GFDe two-tailed, non-parametric Mann-Whitney test, CD versus controlsEmA endomysial antibodies, tTG tissue transglutaminase, GP2 glycoprotein 2, ASCA anti-Saccharomyces cerevisiae antibodies.Prevalence and levels of antibodies in patients and controls.
