Abstract
Objective:At present, there is no reliable indicator for dietary compliance and disease severity in patients with celiac disease (CD). The aim of this study is to evaluate mean platelet volume (MPV) level as a biomarker for detection of disease activation, dietary adherence, and assessment of disease severity.Methods:Eighty-one patients with CD and 50 healthy subjects were enrolled in this study. The diagnosis of CD was established by both positive antibodies against endomysium or gliadin and histopathological criteria (lymphocytic infiltration and total villous atrophy in duodenal biopsies).Results:MPV was observed to be significantly higher among CD patients when compared to healthy controls (8.14±0.26 fL vs. 7.82±0.29 fL and p=0.001). Overall dietary adherence rate was 72.8% (58/81 CD patients). After induction of a gluten-free diet, the MPV was significantly lower in the dietary adherent group than non-adherent patients (7.86±0.17 fL vs. 8.07±0.30 fL and p=0.001). The increase of MPV was correlated with Marsh classification (Marsh 3 active CD vs. Marsh 2 active CD vs. Marsh 1 active CD; 8.32±0.27 fL vs. 8.12±0.19 fL vs. 7.98±0.19 fL; p=0.004 and p=0.009).Conclusion:Based on these data, we believe that increased MPV can provide additional benefit to screening in patients with CD. It can indicate the activation of the disease and adherence to the diet.
