Effect of immune-enhanced enteral nutrition on inflammatory response and immune function in elderly patients with septic shock

Objective:To investigate the effect of immune-enhanced enteral nutrition on inflammatory response and immune function in elderly patients with severe septic shock.Methods:From September 2016 to October 2018,58 cases of serious septic shock patients treated in our hospital,were randomly assigned to two groups.A group-enteral nutrition emulsion group(n=29);B group-enteral nutrition mixed suspension group(n=29);The admission day,one week,two week after admission,the index data of patients',inflammation and immune were collected.Results:With the increase of admission time,CD4 and CD4/CD8 levels in the two groups were gradually increased and CD8 levels were gradually decreased.At 1 and 2 weeks after admission,CD4 and CD4/CD8 levels in the observation group were higher than those in the control group(P<0.05),and CD8 levels were lower than those in the control group(P<0.05).Each immunoglobulin index of subjects in both groups increased with the increase of admission time.The IgG and IgM levels of subjects in the observation group were higher than those in the control group(P<0.05).IgA levels of subjects in the observation group were higher than those in the control group at 1 and 2 weeks after admission(P<0.05).With the increase of admission time,the c-reactive protein concentration of subjects in the two groups decreased gradually(P<0.05).One week after admission,there was no significant difference in c-reactive protein between the observation group and the control group(P>0.05).C-reactive protein of subjects in the observation group was higher than that in the control group at 2 weeks after admission(P<0.05).With the increase of admission time,the concentration of plasma diamine oxidase(DAO)in the two groups decreased gradually,and the DAO at different time points in each group showed statistical difference(P<0.05).1 week after admission,there was no significant difference in DAO between the observation group and the control group(P>0.05).At 2 weeks after admission,the DAO of subjects in the observation group was higher than that in the control group(P<0.05).Conclusions:Immune-enhancing enteral nutrition is more helpful to control the inflammatory response in patients of serious septic shock,and it's also can modulate the immune function.
