Özet
BACKGROUND: The role of villous atrophy in apoptosis, a distinctive feature of celiac disease, is a matter of controversy. The aim of this study was to determine the apoptosis rate through immunohistochemical staining for M30 and M65 in celiac disease cases. DESIGN AND SETTING: Analytical cross-sectional study in a tertiary-level center. METHODS: Duodenal biopsies from 28 treatment-naive patients with celiac disease, 16 patients with potential celiac disease, 10 patients with a gluten-free diet and 8 controls were subjected to immunohistochemical staining for the end-apoptotic marker M30 and the total cell death marker M65. H-scores were compared. Several laboratory parameters were recorded concomitantly, and at the one-year follow-up for celiac disease and potential celiac disease patients. RESULTS: There was a significant difference in H-score for M30 expression between the celiac disease, potential celiac disease and gluten-free diet groups (P = 0.009). There was no significant difference in H-score for M65 expression. There was a positive correlation between the H-score for M30 expression and the anti-tissue transglutaminase immunoglobulin A (anti-tTgIgA) and anti-tissue transglutaminase immunoglobulin G (anti-tTgIgG) levels (R = 0.285, P = 0.036; and R = 0.307, P = 0.024, respectively); and between the H-score for M65 expression and the anti-tTgIgA and anti-tTgIgG levels (R = 0.265, P = 0.053; and R = 0.314, P = 0.021, respectively). There was no difference between celiac disease and potential celiac disease patients regarding the laboratory parameters selected. CONCLUSION: The rates of apoptosis and nutritional deficiencies in patients with potential celiac disease were similar to those in patients with celiac disease.
