[Risk factors analysis for steroid-resistant acute graft versus host disease after haploidentical hematopoietic stem cell transplantation].

Objective: To analyze the risk factors of steroid resistant acute graft- versus-host disease (aGVHD) after haploidentical hematopoietic stem cell transplantation (haplo-HSCT) . Methods: The clinical data of adult patients with acute myeloid leukemia (AML) /Myelodysplastic syndrome (MDS) who developed aGVHD after haplo-HSCT in Peking University Institute of Hematology from January 1st, 2010 to December 31st, 2012 were retrospectively reviewed. Results: A total of 85 patients were enrolled in the study, including 55 males and 30 females, with a median age of 30 (19-67) years. After steroid therapy, there were 53 (62.4%) , 6 (7.1%) and 26 (30.6%) patients achieved complete remission (CR) , partial remission (PR) and non-remission (NR) , respectively. The CR rates of the grade Ⅰ/Ⅱ and Ⅲ/Ⅳ aGVHD by steroid therapy were 66.2% (51/77) vs 25.0% (2/8) (χ(2)=3.639, P=0.048) , respectively. The CR rates of the patients with aGVHD involving 1 target organ and 2 target organs were 77.4% (48/62) vs 21.7% (5/23) (χ(2)=22.157, P<0.001) . The CR rates of patients with standard risk (SR) and high risk (HR) Minnesota risk score was 67.5% (52/77) vs 12.5% (1/8) (χ(2)=7.153, P=0.004) . The mononuclear cells≥8.33×10(8)/kg and the HR Minnesota risk score were independent risk factors for steroid-resistant aGVHD in multivariate analysis. Between Minnesota risk score SR (77 cases) and HR (8 cases) groups, the OS rates at 22 months after transplantation were (90.3±3.8) %vs (75.0±15.3) % (χ(2)=2.831, P=0.092) . After steroid treatment for aGVHD, the OS rates at 22 months in the CR group (53 cases) and non-CR group (32 cases) were (95.2±3.4) %vs (78.6±7.9) % (χ(2)=5.287, P=0.021) respectively. Conclusion: The Minnesota risk score and mononuclear cells count are effective tool for predicting steroid-resistant aGVHD after haplo-HSCT.
