Objective To assess the incidence,risk factors and mortality of acute kidney injury(AKI)in patients with chronic myelogeneous leukemia(CML)after myeloablative allogenetic hematopoietic stem cell transplantation(HSCT). Methods Renal function in 93 CML patients undergone myeloablative allo-HSCT was retrospectively analyzed by the RIFLE criteria. Results Thirty-nine patients (41.9%) developed AKI at a median of 40 days after allo-HSCT, including 24 AKI-R patients(25.8%), 10 AKI-I patients(10.8%) and 5 AKI-F patients (5.4%). The morbidity of AKI in patients with ≥Ⅲ acute graft-versus-host disease (aGVHD) and without <Ⅲ GVHD was (81.82±11.63)% and (36.59±5.32)% (P=0.0037)rospectively. The morbidity of AKI in patients with increased total bilirubin and without increased total bilirubin was (72.73±13.43)% and (37.04±5.37)%(P=0.0192) respectively. ≥Ⅲ aGVHD was peor-prognostic factor of AKI and RR was 2.773 [95%CI (1.073-7.167), P=0.035]. RR of AKI-I and AKI-F in patients with ≥Ⅲ aGVHD was 6.320195%CI (1.464-27.291), P=0.013]. The mortality within 100 days after allo-HSCT of patients with AKI was significantly different as compared to patients without AKI (P=0.001). Six-mouth survival rates of different class AKI patients after myeloablative allo-HSCT were (86.96±7.02)% (AKI-R), (70.00±14.49)% (AKI-I), 0 (AKI-F) (P=0.000)respectively. Conclusions AKI is one of the main complications in CML patients after myeloablative allo-HSCT. ≥Ⅲ aGVHD and increased total bilimbin are poor-prognostic factors of AKI, and higher morbidity of AKI-I and AKI-F can be found in patients with ≥Ⅲ aGVHD. With the deteriorated AKI, 6-month survival is decreased. RIFLE criteria is sensitive to the early diagnosis of renal function. Moreover RIFLE can monitor the progression of AKI and predict the clinical outcome.
