The tissue factor expression on CD14++CD16-monocytes is a new markers in the Chinese Han older adult population with sepsis: A prospective study.

Abstract

OBJECTIVE:

To investigate the tissue factor (TF) expression on different subsets of monocyte and tissue factor secretion of peripheral blood and evaluate their association with the prognosis of sepsis in the Chinese older adult population.

METHODS:

Monocyte subsets and TF expression on different subsets of monocyte were measured using flow cytometry in 80 older adult sepsis patients and 40 age and sex matched healthy controls. Plasma level of TF was measured using ELISA (enzyme-linked immunosorbent assay) method.

RESULTS:

TF expression on CD14++CD16- (MO1) monocyte was lower in death (28-day non-survivor) group compared with survival (28-day survivor) groups [1.01 % (0.58 %, 1.62 %) vs. 3.66 % (1.32 %, 6.93 %), p = 0.001]. The plasma level of TF was increased in death group compared to survival group according to the 28-day mortality [109.2 (67.3, 154.2) vs. 62.1 (44.7, 115.5) pg/mL, p = 0.031]. Logistic regression analysis showed TF expression on MO1 monocyte (β = -0.776, OR = 0.460, CI: 0.251, 0.843, p = 0.012) was independently associated with the 28-day mortality. The ROC (receiver operating characteristic) curve showed that the AUC (area under the curve) of the TF expression on MO1 monocyte for predicting 28-day mortality was 0.846 (p < 0.001).

CONCLUSION:

The TF expression on CD14++CD16- monocyte is a new marker for the prognosis of older adult sepsis.
