title: [Clinical analysis of acute renal failure after allogeneic hematopoietic stem cell transplantation].
abstract: The aim of this study was to investigate the incidence, risk factors of acute renal failure (ARF) after allogeneic hematopoietic stem cell transplantation (allo-HSCT), and evaluate its effect on the prognosis of patients after allo-HSCT. A retrospective analysis was performed in 86 patients undergoing allo-HSCT at Peking University First Hospital from June 2003 to April 2007. ARF is defined as a doubling of baseline serum creatinine at any time during the first 100 days post-transplant. The risks of ARF and mortality after ARF were examined using univariate analysis and multivariate unconditional logistic regression. The correlation of ARF and survival was examined using Cox regression. The results indicated that 27 patients (31.40%) developed ARF at a median of 59.5 days after transplant (range 1 to 93 days). The univariate analysis showed that elevated risks were severe acute GVHD (OR 6.196; 95% CI 1.121 - 34.249, p = 0.033), sepsis or septic shock (OR 4.184; 95% CI 1.314 - 13.325, p = 0.018) and hyperbilirubinemia (OR 3.709; 95% CI 1.428 - 9.635, p = 0.006). Renal disease before transplant (OR 6.711; 95% CI 1.199 - 37.564, p = 0.027), hypertension (OR 2.067; 95% CI 0.739 - 5.782, p = 0.165), the use of vancomycin (OR 2.133; 95% CI 0.844 - 5.392, p = 0.106) or foscarnet sodium (OR 2.133; 95% CI 0.844 - 5.392, p = 0.106) may be potential risks. Multivariate logistic regression analysis showed that renal disease before transplant (OR 6.288; 95% CI 1.218 - 32.455, p = 0.028), sepsis or septic shock (OR 3.614; 95% CI 1.040 - 12.544, p = 0.043) and hyperbilirubinemia (OR 4.448; 95% CI 1.563 - 12.665, p = 0.005) appear to be independently associated with an increased risk of ARF. Age, gender, baseline serum creatinine level, advanced malignant disease, unrelated-donor, total body irradiation (TBI) and cyclosporine levels were not associated with the development of ARF. Cox regression showed that ARF (RR 2.124; 95% CI 1.016 - 4.441, p = 0.045) was independently associated with survival of patients after allo-HSCT. The mortality of patients with ARF within 6 months post-transplant was significantly higher than that of those without ARF (44.4% vs 8.47%, p < 0.001). It is concluded that the cumulative incidence of ARF after allo-HSCT remains high. Renal disease before transplant, hyperbilirubinemia and sepsis or septic shock are all related factors which can increase the risk of ARF. ARF appears to be independent factor influencing survival of patients after allo-HSCT.
