A new type diabetes-specific enteral nutrition formula regulates immune function in elderly patients with severe acute ischemic stroke / 中华老年医学杂志

ABSTRACT

Objective To investigate the immune disorder in elderly patients with severe ischemic stroke and to explore whether a new type of diabetes-specific enteral nutrition formula can regulate the immune function of these patients.Methods In the randomized controlled prospective study,90 patients aged 60-80 years with acute ischemic stroke and NIHSS score more than 10 and dysphagia were randomized to two groupsreceiving a new type(Group A) of,versus traditional(Group B) diabetes-specific enteral nutrition.30 Patients aged 60-80 years with acute ischemic stroke and NIHSS score ≥10 without dysphagia were enrolled as control(Group C).The immune function was observed,and the nutritional status and immunological function were compared between two different enteral nutrition groups at 7 days of treatment.Results After 7 day follow-up,the serum lipid stats significantly ameliorated in group A.An obvious suppression of immune state was observed in severe acute ischemic patients at onset of 7 days.At day 7 of treatment,the percentage of CD3+ T cells in group A was(69.25±9.93)％ after treatment vs.(63.36±7.79)％ at baseline(P＜0.001),and CD3 +CD4+T cells was(45.79±9.47)％ after treatment vs.(36.12±9.15)％ at baseline(P＜0.001),as well as CD4+/CD8+ cells were(2.27±1.40)％ after treatment vs.(1.70±0.82)％ at baseline(P=0.001).At 7 days of treatment,the percentage of CD3+ T cells was higher in group A (69.25 ±9.93) ％ than in group B(63.07± 9.47) ％ (P＜0.001),and the percentage of CD3 + CD4 cells was higher in group A(45.79 ± 9.47) ％ than in group B(41.32 ± 8.89) ％ (P=0.024).Conclusions Enteral nutrition preparations can provide sufficient energy support in the acute ischemic stroke.Immunosuppressive state exists in patients with acute phase of severe ischemic stroke.The new type of diabetic enteral nutrition formula can significantly improve immunosuppressive state in patients with acute severe stroke.
