Abstract Abstract 4322 Background Single nucleotide polymorphisms (SNPs) in the innate immunity receptor NOD2/CARD15 have been demonstrated to modulate the outcome of allogeneic haematopoietic stem cell transplantation. The effect of the NOD2/CARD15 polymorphism seems to be associated with donor source as well as type of conditioning regimen. Methods We reviewed NOD2/CARD15 mutations in all donor/recipient pairs of 192 consecutive patients who received non-myeloablative allogeneic stem cell transplantation(SCT) at our institution between 2002 and 2006. All patients were treated uniformly with fludarabine 30 mg/m2/day for 3 days followed by 200 cGy TBI (n=154) or TBI alone (n=38) and received grafts from HLA-matched related (n=132) or unrelated (n=60) donors. Results Mutated alleles were observed in 36 of 192 (19%) patients and in 35 of 192 (18%) donors. These SNPs, however, did not have a significant impact on clinical outcome data (P > 0.05, Kaplan Meier and Fine & Gray's test). Acute graft-versus-host disease (GVHD) occurred in 24 of 61 (39%) patients with the polymorphism and in 66 of 131 (50%) patients without the polymorphism. Chronic GVHD developed in 28 of 55 (51%) patients with SNP pairs and in 79 of 121 (65%) patients with the wild type. The incidence of transplant-related mortality was 21% in both groups, 13 of 61 patients in the group with the polymorphism and 27 of 131 without the polymorphism. Relapse was seen in 23 of 61 (38%) patients with the SNP pairs and in 48 of 131 (37%) wild type patients. Finally, overall survival was 43% (26/61) in patients with the polymorphism and 39% (51/131) in patients without the polymorphism. Conclusion These data indicate that mutations in the NOD2/CARD15 genes do not influence the clinical outcome of non-myeloablative allogeneic SCT directly. Since NOD2/CARD15 variants are not recognized as a single significant prognostic factor, screening for NOD2/CARD15 when selecting a donor does not seem to have additional value in patients undergoing non-myeloablative SCT.

Abstract Three single nucleotide polymorphisms (SNP) in NOD2/CARD15 have been associated with the incidence and severity of acute GVHD following allogeneic stem cell transplantation (allo-SCT). The potential clinical influence of SNP in NOD2/CARD15 in a model of allo-SCT with a low incidence of GVHD, such as T-cell depleted transplants (TCD), has not been studied. We analyzed the association of SNP in NOD2/CARD15 with the outcome of 84 patients undergoing allo-SCT with TCD by means of CD34+ selection. Results were compared with a concurrent group of 94 patients receiving an allo-SCT with unmanipulated grafts (Non-TCD). Transplants were performed in a single institution, donors were HLA identical siblings and all patients received myeloablative-conditioning regimen. Median follow-up was of 30.6 months (range, 0.2–112). SNP 8, 12 and 13 were analyzed by RT-PCR allelic discrimination method in all patients and in 137 donors. SNP in NOD2/CARD15 were detected in 13.8% of patients and in 10.7% of donors. Results of the association of patient’s NOD2/CARD15 genotype and outcome are given in the table. In TCD transplants, independent risk factors associated with event free survival in a multivariate analysis were: patient’s NOD2/CARD15 genotype (RR 2.7, p=0.02), patient’s age (RR 2.3, p=0.03) and conditioning with radiotherapy (RR 2.7, p=0.03). The only association of donor’s NOD2/CARD15 genotype with clinical outcome in the multivariate analysis was with acute GVHD (RR 3.3, p=0.03). In conclusion, polymorphisms in NOD2/CARD15 have a strong association with clinical outcome in TCD transplants, which is independent of GVHD.
