Abstract:
Objective To evaluate the effect of continuous renal replacement therapy (CRRT) on the remove of inflammatory mediators and the function of endothelial cells in patients with multiple organ dysfunction syndrome (MODS). Methods Thirty patients with MODS were enrolled in this study. All of the patients underwent CRRT for at least 24 hours. Peripheral blood levels of IL-1β, IL-4, IL-6, IL-10, TNF-α, E-selectin, sVCAM-1, slCAM-1 and PAF-AH were measured at the beginning and 3, 6, 12, 24 h after initiation of CRRT. Results Nineteen patients survived after 14 days and 17 patients survived after 28 days during therapy. The clinical oxygenation and bemodynamics were improved after 6 h of CRRT. Among inflammatory mediators, the levels of TNF-α, IL-6, IL-10 rose gradually from the beginning [(462.24±331.03) ng/L, (106.39±90.82) ng/L, (124.51±118.39) ng/L), and reached the peak at 12 h [(887.88±975.46) ng/L, (132.01±118.14) ng/L, (167.01±161.66) ng/L], and the levels of IL-1β, IL-4 decreased from initiation of CRRT. But there were no significant differences in the levels of above cytokines between at the beginning and at the end of CRRT. There were significant differences in the levels of cytokines between survival and death group. The level of IL-6 in death group [(145.45±14.28) ng/L] was significantly higher than that in survival group [(106.03±10.86) ng/L]. The level of IL-10 in death group [(94.93±16.09) ng/L] was significantly lower than that in survival group [(143.06± 12.24) ng/L]. Levels of E-select, sVCAM-1 and sICAM-1 elevated from the beginning and reached the peak at 12 h, but no significant differences were found between intiation and the end of CRRT. The level of PAF-AH increased after initiation, and there was a significant difference between beginning and the end of CRRT. Levels of cytokines for endothelial cell function were significantly different, such as E-selectin [(287.13±42.70) μg/L vs (266.26±65.26) μg/L], sVCAM-I [( 1697.25± 475.24) μg/L vs (1488.10±691.67) μg/L], sICAM-1 [(975.33±142.50) μg/L vs (835.40±332.41) μg/L], and PAF-AH [(9.07±6.38 ) μg/L vs (16.32±8.95)μg/L]. Conclusions Clinical oxygenation and hemodynamics can be improved, and endothelial cell function can be improved partly by CRRT. There were no significant differences of inflammatory mediator levels between initiation and the end of CRRT. IL-6 and IL-10 can be used as predicators for prognosis of MODS patients.
