ABSTRACT
Objective To evaluate the value of immune cell functional assay (ImmuKnow CD4+ T cell ATP assay) in monitoring immune status in renal recipients.Methods A total of 131 adult renal transplant recipients who received transplantation for the first time were under investigation.According to the dynamic monitoring ATP concentration before operation,2 week,1,3,6 months after operation and during infect or rejection,samples were divided into the following groups:health control group (HC),pretransplant (Pre-Tx) group,stable (Tx) group,infect group,acute rejection (AR) group,acute kidney injury (AKI) group.Immune cell functions were detected by ImmuKnow CD4+ T cell ATP assay.Lymphocyte subsets (CD4+/CD8+) were analysed and serum concentrations of FK506 were tested.Mixed lymphocyte reaction(MLR) was analysed.Results The ATP concentration was no significant difference between Pre-Tx and HC group.The ATP concentration of 2 weeks,1 months after operation were significantly higher than Pre-Tx group (P < 0.01).After 3 months,6 months follow-up,the ATP concentration stabilized with time.The ATP concentration of AR group was significantly higher than other three groups (Tx,infect and AKI group,all P < 0.05).The correlation coefficient between the ATP concentration and MLR,CD4+/CD8+,FK506 level were R2=0.0072,R2=10-6,R2=0.004 respectively (all P > 0.05).Conclusions The cell-mediated immunity of recipients is relatively strongger during the first month after transplantation.The ATP concentration is not related to the levels of MLR,CD4+/CD8+,FK506.ImmuKnow ATP assay is a valuable predictor in acute rejection diagnosis.
