Abstract

OBJECTIVE:

To investigate the efficacy, safety and cost of treating patients with acute kidney injury (AKI) and diabetic nephropathy (DN) with continuous renal replacement therapy (CRRT) or sustained low-efficiency daily diafiltration with hemofiltration (SLEDD-f).

SUBJECTS AND METHODS:

Medical records of patients with AKI/DN from January 2006 to December 2012 were reviewed. Fifty-five patients who received CRRT and 52 who received SLEDD-f were included in the study. CRRT and SLEDD-f were performed for 20-72 h per session and 8-10 h per session, respectively. Mortality and renal function recovery rates were evaluated 30 days after the initiation of renal replacement therapy (RRT) and APACHE-II and SOFA scores, anticoagulant dose, inflammatory indices and cost were calculated at baseline and at the end of RRT.

RESULTS:

Of the 55 patients treated with CRRT, 49 (89.1%) had a 30-day survival rate and 30 (54.5%) had a 30-day renal recovery rate. Of the 52 patients with SLEDD-f, these rates were 92.3% (n = 48) and 61.5% (n = 32), respectively. The dosage of low-molecular-weight heparin in the CRRT and SLEDD-f groups was 15,230 ± 1,460 and 6,320 ± 490 U/day, respectively. The cost of hemopurification and the total cost for patients treated with CRRT was CNY 28,628 ± 5,576 (USD 4,210 ± 820) and CNY 38,828 ± 6,324 (USD 5,710 ± 930), respectively. These were higher than those for patients treated with SLEDD-f at CNY 13,260 ± 1,564 (USD 1,950 ± 230) and CNY 19,720 ± 2,652 (USD 2,900 ± 390), respectively.

CONCLUSIONS:

SLEDD-f offered a similar chance of renal recovery and also had further advantages such as a lower heparin dosage, a shorter therapy time and lower hospitalization costs for patients than CRRT. Studies with larger, randomized sample sizes are needed to confirm these findings.
