AbstractThe aim of the present study was to identify factors associated with the risk of development of gastrointestinal acute graft-versus-host disease (GI-aGVHD), as well as to evaluate the impact of various baseline parameters on response to treatment, nonrelapse mortality (NRM), and overall survival (OS) in pediatric patients with GI-aGVHD after allogeneic hematopoietic stem cell transplantation (allo-SCT). We retrospectively analyzed 300 pediatric patients who underwent allo-SCT from HLA-matched related or volunteer unrelated donors in our institution. GI tract involvement was observed in 46 out of 133 patients with aGVHD grade II-IV. Severe aGVHD (grade III-IV) was more frequently observed among patients with GI-aGVHD in comparison with patients without GI involvement (P < .001). Treatment with steroids resulted in durable responses in 22/46 patients; 14 additional patients responded to salvage therapy, whereas 10 were refractory to all treatments administered. Using Cox regression analysis, we observed that serum albumin level ≥ 3 mg/dL on day 5 after the initiation of therapy with steroids was statistically significantly associated with decreased hazard of NRM and improved OS (P = .021 and P = .026, respectively). In our study, serum albumin level, early (+ day 5) after the onset of steroids in patients with GI-aGVHD, was a predictor of treatment outcome. Prospective randomized trials need to be performed to verify the predictive significance of serum albumin and the need for early intensification of immunosuppressive treatment.2011 American Society for Blood and Marrow Transplantation.
