Outcomes of patients with end-stage renal disease (ESRD) under chronic hemodialysis requiring continuous renal replacement therapy (CRRT) and patients without ESRD in acute kidney injury requiring CRRT: a single-center study.

In most continuous renal replacement therapy (CRRT) studies, end-stage renal disease (ESRD) patients were excluded and the outcomes of patients with ESRD treated with chronic hemodialysis (HD) were unknown. The purposes of this study were to (1) evaluate short-term patient survival and (2) compare the survival of conventional HD patients needing CRRT with the survival of non-ESRD patients in acute kidney injury (AKI) requiring CRRT. We evaluated adults (>18 years) requiring CRRT who were treated in the intensive care unit (ICU) at Kosin University Gospel Hospital from January 1, 2009 to December 31, 2010. A total of 100 (24 ESRD, 76 non-ESRD) patients underwent CRRT during the study period. Patients were divided into two major groups: patients with ESRD requiring chronic dialysis and patients without ESRD (non-ESRD) with AKI. We compared the survival of conventional HD patients requiring CRRT with the survival of non-ESRD patients in AKI requiring CRRT. For non-ESRD patients, the 90-day survival rate was 41.6%. For ESRD patients, the 90-day survival rate was 55.3%. Multivariate Cox proportional hazards analyses demonstrated that conventional HD was not a significant predictor of mortality (hazard ratio [HR]: 0.334, 95% confidence interval [CI]: 0.063-1.763, P = 0.196), after adjustment for age, gender, presence of sepsis, APACHE score, use of vasoactive drugs, number of organ failures, ultrafiltration rate, and arterial pH. The survival rates of non-ESRD and ESRD patients requiring CRRT did not differ; ESRD with conventional HD patients may be not a significant predictor of mortality.

Timing for initiation of continuous renal replacement therapy in patients with septic shock and acute kidney injury.

The optimal timing for renal replacement therapy initiation in septic acute kidney injury (AKI) remains controversial. This study investigates the impact of early versus late initiation of continuous renal replacement therapy (CRRT) on organ dysfunction among patients with septic shock and AKI. Patients were dichotomized into "early" (simplified RIFLE Risk) or "late" (simplified RIFLE Injury or Failure) CRRT initiation. Patients with chronic kidney disease stage 5 or those on long-term dialysis were excluded. Organ dysfunction was quantified by Sequential Organ Failure Assessment (SOFA) score. From January 2008 to June 2011, 120 patients fulfilled the inclusion criteria. Thirty-one (26%) underwent "early" while 89 (74%) had "late" CRRT. No significant difference was noted between groups on improvement of total SOFA/non-renal SOFA score or noradrenaline equivalent in the first 24 and 48 h after CRRT initiation. Dialysis requirement and mortality (at 28 days, 3 months and 6 months) did not differ. In conclusion, improvement of non-renal SOFA score 48 h after CRRT correlated with SOFA score on CRRT initiation (P = 0.040) and APACHE IV risk of death (P = 0.000), but not estimated glomerular filtration rate on CRRT initiation (P = 0.377). Improvement of non-renal SOFA score correlated with SOFA score on CRRT initiation and APACHE IV risk of death. However, this retrospective review cannot identify any significant clinical benefit of early CRRT initiation in patients presenting with septic shock and AKI.
