Effect of continuous blood purification on T lymphocyte subsets and inflammatory response in patients with severe sepsis

摘要

Objective:To investigate the effects of continuous blood purification (CBP) on T lymphocyte subsets and inflammatory response in patients with severe sepsis, and to provide scientific evidence for the treatment of severe sepsis patients. Methods:96 cases of severe sepsis patients from June 2013 to June 2016 in Yulin First People''s Hospital were as the research subjects, randomly divided into observation group and control group, 48 cases in each group. The control group received routine treatment of sepsis, while the observation group adopted CBP therapy on the basis of the control group, fasting venous blood was collected 7 d before and after treatment respectively, and the change of IL-6, TNF-α, CRP levels, CD3+, CD4+, CD8+lymphocyte percentage and ratio of CD4+/CD8+in two groups were compared before and after treatment in two groups. Results:Before treatment, there were no significant differences in IL-6, TNF-α, and CRP levels between the two groups (P>0.05). After treatment, the IL-6 and TNF-αlevels of observation group and the control group were significantly decreased, CRP level in the observation group decreased significantly, and the IL-6, TNF-αand CRP levels were significantly lower in the observation group than in the control group (P<0.05). Before treatment, there was no statistical difference in the percentage of T cell subsets between the two groups (P<0.05). After treatment, the two groups of patients with CD3+, CD4+, CD8+and CD4+/CD8+were significantly elevated (P<0.05). After treatment, the CD3+, CD4+and CD4+/CD8+were significantly higher in the observation group than in the control group (P<0.05). Conclusions:CBP therapy can effectively reduce the level of inflammatory factors in patients with severe sepsis, reduce the inflammatory response, and can effectively improve the immune function of patients, and the effect is significant.
