Abstract
Background: Despite advances in immunosuppression, acute allograft rejection remains one of the key factors affecting patient and graft survival in pediatric kidney transplantation. The aim of the study is to evaluate the role of serum soluble IL2 receptor (sIL2R) level as a noninvasive assessment parameter of acute rejection (AR). Method: Serum sIL2R level was measured (using enzyme-linked immune-sorbent assay technique) in 60 pediatric kidney transplant recipients (30 recipients with AR and 30 transplant recipients with stable graft function). Results: The mean values of sIL2R level in patients experiencing AR (14.8 ± 6.54) ng/mL were significantly higher than that in patients with stable graft functions (6.44 ±1.95) ng/mL (p = 0.0001). In addition; patients with AR proved by graft biopsy had their mean values of sIL2R level (16.19 ± 7.48) ng/mL significantly higher than that of other recipients in the study population (p = 0.032). Conclusion: Serum sIL2R level may serve as a noninvasive diagnostic indicator in pediatric kidney transplant recipients experiencing AR.
