• human beta-defensins
• villous atrophy

As infection influences the pathogenesis and presentation of celiac disease, we investigated the expression of natural antibiotics in this condition. Twenty-three adults were prospectively studied: 10 controls and 13 subjects with untreated celiac disease. Distal duodenal biopsies were taken at baseline and after 6 months of a gluten-free diet and assessed for the expression of natural antibiotics. Epithelial human beta-defensin 1 in subjects with celiac disease had a median of 0.02 unit at baseline, compared with 0.34 unit in controls (P < 0.001). It correlated negatively with the degree of villous atrophy (r = -0.64, P = 0.019) and rose to 0.04 unit on the gluten-free diet (P = 0.035 vs. baseline, P < 0.001 vs. controls). The expression of other antibiotics was unchanged. The expression of epithelial natural antibiotics is limited in celiac disease.
