Objective: To compare the clinical effects between continuous renal replacement therapy (CRRT) and intermittent haemodialysis (IHD) for the treatment of sepsis-induced acute kidney injury (AKI). Methods: A prospective study was conducted. Seventy-three patients with sepsis-induced AKI admitted to the intensive care units (ICUs) of Tianjin Hospital and Tianjin First Center Hospital from January to December in 2014 were enrolled. They were randomly divided into two groups: CRRT group (n = 35) and IHD group (n = 38). Data were recorded for the patients in two groups before treatment, including acute physiology and chronic health evaluation Ⅱ (APACHE Ⅱ) score, mean arterial pressure (MAP), urine volume, and the levels of C-reactive protein (CRP) and serum creatinine (SCr) before and 1 week after treatment, the time of recovery of urine volume, the length of ICU stay, the duration of organ support, and the incidence of cardiovascular events. Results: There was no statistically significant difference in APACHE Ⅱ scores (21.63±2.46 vs. 21.34±2.46), MAP [mmHg (1 mmHg = 0.133 kPa): 71.26±10.70 vs. 75.74±15.17], urine volume (mL: 404.00±79.13 vs. 438.97±87.17), CRP (mg/L: 100.94±14.73 vs. 95.17±27.03), and SCr (μmol/L: 394.02± 50.26 vs. 390.47±54.42) before treatment between CRRT group and IHD group (all P > 0.05). One week after treatment, compared to the IHD group, CRRT could dramatically reduce the levels of CRP (mg/L: 41.05±10.15 vs. 60.21±14.78, t = 6.401, P < 0.001), SCr (μmol/L: 185.97±65.48 vs. 232.02±71.93, t = 2.862, P = 0.006), urine output recovery time (days: 7.94±3.06 vs. 11.08±3.71, t = 3.923, P < 0.001), the length of ICU stay (days: 9.54±3.39 vs. 13.42±3.89, t = 4.521, P < 0.001), organ support time (days: 3.23±2.70 vs. 6.34±3.36, t = 4.343, P < 0.001), and the incidence of cardiovascular events [23.53% (8/35) vs. 39.47% (15/38), χ2 = 5.509, P = 0.025]. Conclusion: Compared to IHD, CRRT can more efficiently help patients with sepsis-induced AKI in removing excessive water, metabolic waste, and lower the levels of pro-inflammatory cytokines, maintain homeostasis of the internal environment, lower the adverse effects on cardiovascular system, so that it significantly improve the prognosis of patients, shorten the time of organ support and the length of ICU stay.
