Abstract

Introduction: The purpose of this study was to evaluate the correlation of plasma citrulline and rejection episodes in intestinal transplantation. Methods: From January 2007 until present, we performed citrulline assays on our small bowel patients. We investigated the correlation of these assays with the rejection status of the patients. The rejection status of the graft was defined based on graft biopsies. Results: Of 5195 citrulline samples, average serum citrulline levels decreased significantly when the patients presented a rejection episode. We found the following: no rejection, 17.38 μm/L; mild rejection, 13.05 μm/L; moderate rejection, 7.98 μm/L; and severe rejection, 6.05 μm/L. Our current emphasis is to determine the predictive power of citrulline with other biomarkers versus as a separate and isolated measurement. Conclusions: In our study, citrulline levels correlated significantly with the rejection status of the graft. Serial follow-up of the patients using this assay may alert us to the possibility of increased alloreactivity and rejection episodes.
