A multicenter, retrospective study of acute kidney injury in adult patients with nonmyeloablative hematopoietic SCT.

摘要

Acute kidney injury (AKI) is a common early complication in patients with hematopoietic SCT (HSCT). However, there are limited data about the incidence and risk factors of AKI in patients with nonmyeloablative HSCT. We conducted a multicenter, retrospective cohort study of 62 patients from three institutions who were treated with similar protocols for nonmyeloablative HSCT. AKI was classified according to the Acute Kidney Injury Network criteria. It was shown that 29% of the patients developed AKI in the first 100 days after nonmyeloablative HSCT. The risk factor at baseline for AKI was incomplete HLA-matched transplant (odds ratio (OR) 3.6; 95% confidence interval (CI) 1.1-13.0). Complications such as acute GVHD, veno-occlusive disease of liver and sepsis were also associated with the development of AKI (OR 12.1; 95% CI 2.4-62.4). AKI was significantly associated with mortality (OR=4.7; 95% CI 1.9-11.5). We concluded that AKI is a very common complication in patients with nonmyeloablative HSCT, which is associated with incomplete HLA-matched transplant and complications, and has an important impact on the patients' first year of survival.
