ABSTRACT
BACKGROUND AND OBJECTIVE:
Allogeneic hematopoietic cell transplantation (allo-HSCT) is a potent procedure for the treatment of hematologic diseases, yet it is associated with high risks of treatment-related complications. Except for transplant-related organ toxicities, renal insufficiencies which emerge earlier significantly limit patients' long survival. To analyze risk factors for acute kidney injury (AKI), we conducted a retrospective cohort study of 96 patients undergoing HSCT.METHODS:
During the first 100 days after allo-HSCT, all patients were evaluated for renal function by measuring serum creatinine clearance and glomerular filtration rate (GFR) with a classification below Grade 0 (<25%, decline in creatinine clearance), Grade 1 (≥25% decline in creatinine clearance but <2-fold increase in serum creatinine), Grade 2 (≥2-fold rise in serum creatinine but no need for dialysis), and Grade 3 (≥2-fold rise in serum creatinine and need for dialysis). Cox regression model was used to calculate the hazard ratios (HRs) of demographic data, clinical variables, and risk factors for AKI.RESULTS:
Twenty-eight (29.2%) patients occurred Grades 1-3 renal dysfunction (Grade 1, 14 patients; Grade 2, 12 patients; Grade 3, 2 patients), and ratios of early kidney injury increased in high-risk malignancy group (HR = 2.945, 95% confidence interval (CI)=1.293-6.421), patients treated with myeloablative conditioning regimen (HR=2.463, 95% CI=1.757-4.320), and patients with acute GVHD (HR=3.553, 95% CI=1.809-6.978), sepsis (HR=3.215, 95% CI=1.189-6.333 ), or hepatic veno-occlusive disease (VOD) (HR=3.487, 95% CI=1.392-6.524). Whereas, HLA histocompatibility showed no striking increased risk for acute renal injury (HR=1.684, 95% CI=0.648-4.378). The survival rate was lower in patients with severe nephrotoxicity (21.4%) than in patients without nephrotoxicity (70.6%) (P=0.001).CONCLUSIONS:
Nephrotoxicity is the primary risk factor for AKI, severely impacting on survival. Sorts of risk factors mentioned will be useful for evaluation for kidney function of patients undergoing allo-HSCT.
