Assessment of Serum Soluble CD30 Levels in Pediatric Kidney Transplant Recipients

Abstract

BACKGROUND: CD30 is considered to be a marker for the activated immune system; however, its association with acute rejection and kidney graft function showed severe heterogeneity. AIM: The aim of this study is to examine the predictive value of soluble CD30 (sCD30) levels for kidney transplantation (KT) outcomes in children. MATERIALS AND METHODS: CD30 in serum was measured by ELISA technique in 50 pediatric kidney transplant recipients (KTRs) within 13.4 ± 4.5 days before and within 19.5 ± 9.2 days after KT. sCD30 values were correlated with clinical, laboratory, and immunosuppressive (IS) therapy data and graft function of included patients. Twenty age/gender-matched healthy controls participated as reference values for sCD30 levels. RESULTS: Our study revealed that serum levels of CD30 showed a significant relation between serum sCD30 levels: Pre/post-transplantation (p = 0.02) with increasing sCD30 levels after transplantation (71.60 pg/mL vs. 90.20 pg/mL). In the time, there were no relations between sCD30 with other parameters. CONCLUSIONS: Our results suggest that the measurement of serums CD30 levels may be used as a valuable biomarker in renal transplantation when it is measured pre/post-transplantation.
