Effects of continuous blood purification on inflammation and nutritional status in patients with sever sepsis / 中华急诊医学杂志

ABSTRACT

Objective To study the effect of continuous blood purification on inflammation and nutritional status in patients with sepsis, and to study relationship between inflammatory, malnutrition and illness. Method Forty-eight patients with severe sepsis were randomly divided into two groups: continuous renal replacement treat-ment (CRRT) group (n=27) and control group (n=21). The flowing biomarkers including albumin, preallbu-min, transfenin, insulin-like growth factor-1 (IGF-1), tumor necrosis factor (TNF-α) and C reactive protein (CRP) were determined before,and 1 week and 2 weeks after treatment. Results Compared with control group, levels of albumin, prealbumin and IGF-1 in treatment group increased significantly at 14 days after CRRT (P<0.05), and levels d CRP and TNF-α decreased significantly (P<0.05), resulted in increase in survival rate, shortened me-chanical ventilation time and decreased SOFA scores (P<0.05). The IGF-1 and prealbumin had a negative cor-relations with CRP and TNF-a in both groups (P<0.05). The survivors in both groups had significantly higher levels of IGF-1,prealbumin and TNF-α than the deads before trearment(P<0.05). Conclusions Continuous blood purification can effectively attenuate inflammation and improve nutritional status in patients with severe sep-sis.Maybe IGF-1 and prealbumin act as prognostic markers more sensitive in severe sepsis.
