CD4 + CD25 + T regulatory cells in predicting the prognoses of patients with sepsis / 中华急诊医学杂志

ABSTRACT

Objective We aimed to evaluate the role of CD4 + CD25 + T regulatory cells in predicting the prognoses of patients with sepsis.Methods Patients with sepsis in Shanghai Changzheng Hospital from December 2013 to April 2014 were identified and grouped into survival group (SG,n =19) and death group (DG,n =9) in accordance with their clinical outcomes.CD4 + CD25 +T regulatory cell ratio,C-replication protein,bilirubin,procalcitonin,and coagulation function were tested on the 1st day and 7th day,and APACHE Ⅱ and SOFA were analyzed to assess the predictability of this group of cells.Results Twentyeight patients were identified,with a mean age of (60.36 ± 15.30) years,a mean APACHE Ⅱ score of (16.68±7.00),and a mean SOFA score of (7.18 ±3.78).Twelve (42.9％) of the individuals were accompanied with severe multiple trauma,and 10 (35.7％) were in septic shock,and 9 (32.2％) died of severe sepsis.The first day CD4 + CD25 + T regulatory cell ratios on the first day were 2.10％ (0.80,3.10)％ (SG) vs.1.80％ (1.15,3.65)％ (DG) (Z=-0.148,P=0.883),andonday7 were 0.90％ (0.30,2.80)％ (SG) vs.5.70％ (2.60,8.30)％ (DG) (Z=-2.905,P=0.004) presented significant predictability.Conclusions Dynamic monitoring of CD4 + CD25 + T regulatory cells could predict the prognoses of patients with sepsis and should be generalized in clinical emergency practice.
