Goals:
To validate cut-off values of CD3 T-cell receptor gamma-delta chain (TCRγδ) intraepithelial lymphocyte (IEL) in the (differential) diagnosis of celiac disease (CD).
Background:
CD is characterized by an increase in gamma-delta IEL (CD3TCRγδ IEL).
Study:
Percentages were determined by flow cytometric analysis of IELs from small bowel biopsies in 213 CD and 13 potential CD (PCD) patients and in total 112 controls. A cut-off value for percentages of CD3TCRγδ IEL to differentiate active CD and controls was obtained from a receiver operating characteristic curve and implemented in controls and PCD patients.
Results:
Percentage of CD3TCRγδ IEL was significantly increased in the majority of CD patients, irrespective of the presence of villous atrophy. A cut-off value of 14% for CD3TCRγδ IEL resulted in 66.3% sensitivity and 96.6% specificity for CD diagnosis (area under the curve, 88.6%).
Conclusions:
A percentage of ≥14% CD3TCRγδ IEL has a high specificity for CD diagnosis and can be of diagnostic help in cases where diagnosis is not straightforward.

The Y-to-Delta Circuit
The initial step in analyzing a wye-to-delta circuit is to assume a positive phase sequence. These phase voltages are then utilized to calculate the line voltages that occur directly across the delta-connected load impedances. Van, Vbn, and Vcn are the phase voltages in wye, and Vab, Vbc, and Vca are the line voltages for a delta circuit. The relation between...
