Abstract

Acute graft-versus-host disease (AGVHD) severity is usually graded (grades 0-IV) by the pattern of organ involvement using the classic Glucksberg-Seattle criteria (GSC). Recently, the International Bone Marrow Transplant Registry (IBMTR) developed a new Severity Index by regrouping the patterns of organ involvement into five Indexes (0-D) that appeared more predictive of transplant-related mortality (TRM) and transplant failure (TF, relapse or TRM). We studied the predictive value of both grading systems of TRM, TF and GVHD-related mortality (GTRM) in a series of 114 consecutive patients > or = 12 years old allografted from a histocompatible sibling at our institution, 100 of whom were evaluable for AGVHD. The IBMTR Severity Index showed better incremental prediction of TRM (relative risks (RR) of 1, 1.5, 1.4, 2 and 2.5 for Indexes 0, A, B, C and D), TF (RRs of 1, 1.6, 1.6, 2 and 2.3, respectively) and GTRM (RRs of 1, 2.2 and 4.8 for Indexes B, C and D) than the GSC. With the GSC different outcomes for TRM and TF were found only from grade 0 to I-II and 0 to IV or I-III to IV, but not from I-II to III. The GSC also appeared less predictive of GTRM (RRs of 1, 0.4 and 2.9 for grades II, III and IV). In our relatively small patient sample, the new IBMTR Severity Index appeared more predictive of transplant outcome than the GSC, especially between no AGVHD, early Indexes (A-B) and advanced Indexes (C-D).
