evaluation of the mean percentages of the peripheral blood gamma delta t lymphocytes in the healthy subjects and celiac patients in isfahan

background : an elevation in the mean percentages of the gamma delta t lymphocytes per total t cells in the epithelium of the small intestine has a diagnostic value for celiac disease.  this study aimed to measure the percentages of the peripheral blood gamma delta t lymphocytes in the adults' celiac disease and healthy controls. materials and methods: in this case-control study the absolute numbers of the peripheral blood lymphocytes obtained from the controls (n = 21) and celiac patients (n = 15) were studied, using a cell counter. the proportions of the gamma-delta t lymphocytes were evaluated by the flow cytometer method. results: the results showed that there was not significant  i difference in the percentages of the gamma-delta t lymphocytes between celiac patients and healthy individuals ( p value= 0.84 ). conclusions: collectively, the data show that the percentages of the peripheral blood gamma delta t lymphocytes could not be helpful for celiac disease diagnosis.
