Correlation between human leukocyte antigen antibody production and serum creatinine in patients receiving sirolimus monotherapy after Campath-1H induction.
BACKGROUND: In this study, we determined whether Campath-1H induction followed by sirolimus monotherapy inhibited alloantibody production in renal transplantation. Second, we evaluated the correlation between human leukocyte antigen (HLA) antibody production and serum creatinine levels. METHODS: Sera were taken 1 to 24 months after transplantation from 24 patients treated with Campath-1H and sirolimus and tested for serum creatinine and HLA-specific antibody by using flow cytometry and enzyme-linked immunosorbent assay. RESULTS: Ten (42%) of the 24 patients treated with Campath-1H and sirolimus produced HLA antibodies. Six of these 10 developed both donor-specific antibodies (DSAs) and non-donor-specific antibodies (NDSAs), whereas only NDSAs were detected in the other four patients. In patients with biopsy-diagnosed humoral rejection (C4d+), serum levels of both DSA and NDSA significantly correlated with patient serum creatinine levels. Rejection treatment successfully reduced both DSAs and NDSAs and reversed humoral rejection. CONCLUSIONS: The numeric relationship between serum creatinine and DSA levels suggests a causal relationship between alloantibody and transplant rejection.
