Plasma Elevations of Tumor Necrosis Factor-Receptor-1 at Day 7 Postallogeneic Transplant Correlate with Graft-versus-Host Disease Severity and Overall Survival in Pediatric Patients
Biology of Blood and Marrow Transplantation(2008)
Abstract
Tumor necrosis factor-α (TNF-α) is known to play a role in the pathogenesis of graft-versus-host disease (GVHD), a cause of significant morbidity and treatment-related mortality (TRM) after allogeneic hematopoietic stem cell transplantation (HCT). We measured the concentration of TNF-Receptor-1 (TNFR1) in the plasma of HCT recipients as a surrogate marker for TNF-α both prior to transplant and at day 7 in 82 children who underwent a myeloablative allogeneic HCT at the University of Michigan between 2000 and 2005. GVHD grade II–IV developed in 39% of patients at a median of 20 days after HCT. Increases in TNFR1 level at day 7 post-HCT, expressed as ratios compared to pretransplant baseline, correlated with the severity of GVHD (P = .02). In addition, day 7 TNFR1 ratios >2.5 baseline were associated with inferior 1-year overall survival (OS 51% versus 74%, P = .04). As an individual biomarker, TNFR1 lacks sufficient precision to be used as a predictor for the development of GVHD. However, increases in the concentration of TNFR1, which are detectable up to 2 weeks in advance of clinical manifestations of GVHD, correlate with survival in pediatric HCT patients.
