Results

Twenty-nine cases showed positive IgA tTG-Ab (15 men and 14 women, mean age 35.4 years, range 18–59), whereas only five were simultaneously positive for EMA. Except for two subjects with normal small bowel histology (Marsh 0), all other subjects were found to have biopsy findings compatible with GSE: 18 Marsh I, five Marsh II, three Marsh IIIa and one Marsh IIIc lesions. he prevalence of GSE was 0.96% or 1: 104. The sensitivity and specificity of the human-recombinant IgA tTG-Ab assay were 100 and 99%, respectively, whereas the results for IgA EMA were 19 and 100%, respectively. The IgA EMA was positive in cases with advanced mucosal lesions of the small bowel. The mean serum value of IgA tTG-Ab was higher in patients with severe enteropathy compared with those showing slight mucosal changes (P< 0.05).
