- Celiac disease (CeD) is a disease more prevalent and multisymptomatic than was earlier recognized. Whereas prompt initiation of gluten-free diet (GFD) is beneficial in relieving the symptoms, an accurate CeD diagnosis is necessary also to avoid years of restricted diet on uncertain grounds. We propose a new diagnostic method, based on elution of deposited antibodies against transglutaminase (anti-tTG) from duodenal biopsies in patients with symptoms and screening serology analyses suggestive of CeD. The eluates were analyzed in a Phadia 250 fluoroimmunoassay, demonstrating elevated concentrations of anti-tTG in CeD patients, corresponding to serology and histopathology findings. In one case histology was inconclusive, displaying only unspecific inflammation, but eluted anti-tTG was positive. This patient has clinically improved following GFD. We conclude that our novel method represents a new tool in the diagnostic work up in CeD. The detection of deposited anti-tTG at the site of inflammation appears to provide a high sensitivity and specificity using a technique that is quick, simple and reliable. Further studies are needed for optimization and elucidation of suitable applications for this elution method.
