Core Tip

Core tip: We prospectively investigated the differences between celiac disease (CD) (Marsh III) patients with tissue-transglutaminase antibody (tTGA) levels ≥ 100 U/mL and patients with lower tTGA levels. We found that patients with high tTGA more often carried multiple CD-associated heterodimers compared with patients with tTGA < 100 U/mL. In addition, high-tTGA patients have more advanced mucosal lesions that are also less patchy. Phenotypically, high-tTGA patients have a lower body weight and more often present with extraintestinal symptoms compared with patients with lower levels of tTGA, who more often have intestinal symptoms. These results provide further evidence that patients with tTGA ≥ 100 U/mL are truly a distinct group with more advanced disease.
