ABSTRACT
Objective To explore the effect of MICA-Ab expression on the prognosis of sensitized renal transplantation recipients.Methods A total of 51 sensitized recipients (PRA more than 20%) in our hospital from August 2007 to April 2010 were enrolled in the study.In these patients,29 cases received protein A immunoadsorption and detection of MICA-Ab was performed before and after protein A immunoadsorption.Other 22 patients received MICA-Ab detection when they were hospitalized.Associations of PRA,HLA-matches,acute rejection,and serum creatinine of postoperative week 1 and week 4 with MICA-Ab were analyzed retrospectively.Results Sixteen recipients (31.4%) had positive MICA-Ab expression but their acute rejection rate was not higher as compared to the patients with negative MICA-Ab expression.Recipients with PRA>40% showed higher expression level of MICA-Ab than recipients with PRA≤40% (P≤0.05).HLA-match did not show influence on MICA-Ab expression.MICA-Ab positive group had no higher serum creatinine level than negative group in postoperative week 4.MICA-Ab level decreased significantly after protein A immunoadsorption.Conclusions MICA-Ab expression increases in the sensitive recipients but does not influence the prognosis.Protein Aimmunoadsorption can eliminate MICA-Ab effectively in sensitized recipients.
