Abstract
Despite numerous studies, the precise role of Th1/Th2 cytokines in acute renal allograft rejection remains unclear. To provide insight into the role of cytokines in acute allograft rejection, we measured serum T-cell cytokine concentrations for correlation with clinical events after renal transplantation in adults. Serum Th1 (interleukin-2 [IL-2] and interferon-gamma [IFNγ] and Th2 (IL-4, IL-10) cytokine concentrations were measured in 60 consecutive living donor kidney transplant recipients namely, 40 males, overall mean age 38.82 years), on the day before as well as 7 and 14 days posttransplantation using ELISA. Patients were stratified based upon acute rejection episode (ARE) in the first month after transplantation. Immunosuppression consisted of cyclosporine, mycophenolate mofetil, and prednisolone. ARE was diagnosed based on an increased plasma creatinine of more than 50%, sonographic analysis, radioisotope scan, pathologic findings, or measured cyclosporine blood levels. Twelve ARE were diagnosed among patients (20%). There was no significant difference between the 2 groups with respect to the mean serum concentration values of IL-2, IL-10, IL-4, and IFNγ on the day before or 7 or 14 days after transplantation. This study showed that there was no correlation between the Th1/Th2 serum cytokine profiles and early ARE in living donor kidney transplantation.
