Clinical characteristics of sepsis-induced acute kidney injury in patients undergoing continuous renal replacement therapy

摘要

The aim of this study was to investigate the clinical characteristics of sepsis-induced acute kidney injury (AKI) in patients undergoing continuous renal replacement therapy (CRRT). From 2011 to 2015, we enrolled 340 patients who were treated with CRRT for sepsis at the Presbyterian Medical Center. In all patients, CRRT was performed using the PRISMA platform. We divided these patients into two groups (survivors and non-survivors) according to the 28-day all-cause mortality. We compared clinical characteristics and analyzed the predictors of mortality. The 28-day all-cause mortality was 62%. Survivors were younger than non-survivors and had higher platelet counts (178?±?101?×?103/mL vs. 134?±?84?×?103/mL, p??.01) and serum creatinine levels (4.2?±?2.8 vs. 3.3?±?2.7, p??.01). However, survivors had lower red blood cell distribution width (RDW) scores (14.9?±?2.1 vs. 16.1?±?3.3, p??.01) and APACHE II scores (24.5?±?5.8 vs. 26.9?±?5.7, p?0.05?mL/kg/h (66% vs. 86%, p?=?.001) in the first day. In a multivariate logistic regression analysis, age, platelet count, RDW score, APACHE II score, serum creatinine level, and a urine output of 0.05?mL/kg/h the first day were prognostic factors for the 28-day all-cause mortality. Age, platelet count, APACHE II score, RDW score, serum creatinine level, and urine output the first day are useful predictors for the 28-day all-cause mortality in sepsis patients requiring CRRT.
