ABSTRACT
OBJECTIVE@#To explore the characteristics of changes in peripheral blood lymphocyte subsets in patients with sepsis in intensive care unit (ICU) and analyze their predictive value for prognosis.@*METHODS@#The clinical data of sepsis patients admitted to the surgical intensive care unit (SICU) of the First Affiliated Hospital of Zhengzhou University from January 2020 to December 2021 were analyzed retrospectively. The patients met the diagnostic criteria of Sepsis-3 and were ≥ 18 years old. Peripheral venous blood samples were collected from all patients on the next morning after admission to SICU for routine blood test and peripheral blood lymphocyte subsets. According to the 28-day survival, the patients were divided into two groups, and the differences in immune indexes between the two groups were compared. Logistic regression analysis was used to analyze the risk factors of immune indexes that affect prognosis.@*RESULTS@#(1) A total of 279 patients with sepsis were enrolled in the experiment, of which 198 patients survived at 28 days (28-day survival rate 71.0%), and 81 patients died (28-day mortality 29.0%). There were no significant differences in age (years old 57.81±1.71 vs. 54.99±1.05) and gender (male 60.5% vs. 63.6%) between the death group and the survival group (both P > 0.05), and the baseline data was comparable.(2) Acute physiology and chronic health evalution II (APACHE II 22.06±0.08 vs. 14.08±0.52, P < 0.001), neutrophil percentage [NEU% (88.90±1.09)% vs. (84.12±0.77)%, P = 0.001], procalcitonin [PCT (μg/L) 11.97±2.73 vs. 5.76±1.08, P = 0.011], platelet distribution width (fL 16.81±0.10 vs. 16.57±0.06, P = 0.029) were higher than those in the survival group, while lymphocyte percentage [LYM% (6.98±0.78)% vs. (10.59±0.86)%, P = 0.012], lymphocyte count [LYM (×109/L) 0.70±0.06 vs. 0.98±0.49, P = 0.002], and platelet count [PLT (×109/L) 151.38±13.96 vs. 205.80±9.38, P = 0.002], and thrombocytocrit [(0.15±0.01)% vs. (0.19±0.07)%, P = 0.012] were lower than those in the survival group. (3) There was no statistically significant difference in the percentage of lymphocyte subsets between the death group and the survival group, but the absolute value of LYM (pieces/μL 650.24±84.67 vs. 876.64±38.02, P = 0.005), CD3+ absolute value (pieces/μL 445.30±57.33 vs. 606.84±29.25, P = 0.006), CD3+CD4+ absolute value (pieces/μL 239.97±26.96 vs. 353.49±18.59, P = 0.001), CD19+ absolute value (pieces/μL 111.10±18.66 vs. 150.30±10.15, P = 0.049) in the death group was lower than those in the survival group. Other lymphocyte subsets in the death group, such as CD3+CD8+ absolute value (pieces/μL 172.40±24.34 vs. 211.22±11.95, P = 0.112), absolute value of natural killer cell [NK (pieces/μL) 101.26±18.15 vs. 114.72±7.64, P = 0.420], absolute value of natural killer T cell [NKT (pieces/μL) 33.22±5.13 vs. 39.43±2.85, P = 0.262], CD4-CD8- absolute value (pieces/μL 41.07±11.07 vs. 48.84±3.31, P = 0.510), CD4+CD8+ absolute value (pieces/μL 3.39±1.45 vs. 3.47±0.36, P = 0.943) were not significantly different from those in the survival group. (4)Logistic regression analysis showed that lymphocyte subsets were not selected as immune markers with statistical significance for the prognosis of sepsis.@*CONCLUSIONS@#The changes of immune indexes in sepsis patients are closely related to their prognosis. Early monitoring of the above indexes can accurately evaluate the condition and prognosis of sepsis patients.
