The Analysis Of The Levels Of Plasma Inflammation-Related Cytokines And Endotoxins In Patients With Acute Aortic Dissection
CLINICAL HEMORHEOLOGY AND MICROCIRCULATION(2020)
Abstract
OBJECTIVE: To investigate the changes in the levels of plasm interleukin-6 (IL-6), tumor necrosis factor-alpha (TNF-alpha), C-reactive protein (CRP), matrix metalloproteinase-9 (MMP-9) and endotoxins in patients with acute aortic dissection (AAD).METHODS: 55 AAD patients who were admitted and scheduled to undergo emergency surgery in our hospital from January 2017 to July 2017 were selected and retrospectively analyzed. They were divided into the survival group (n = 40) and the death group (n = 15). The levels of plasma IL-6, TNF-alpha, CRP, MMP-9 and endotoxins at admission and at 6 h, 12 h and 24 h after admission (T0, T1, T2 and T3) were measured, and the correlations of inflammatory cytokines with endotoxins were analyzed.RESULTS: At T1, T2 and T3, the levels of inflammatory cytokines and endotoxins were increased. The levels of plasma IL-6, TNF-alpha, CRP, MMP-9 and endotoxins in the death group were significantly higher than those in the survival group at each time point (p < 0.05 in all comparisons). Neutrophil and platelet counts in the death group were higher than those in the survival group (p < 0.05). Correlation analyses indicated that the levels of IL-6, TNF-alpha, CRP and MMP-9 were positively correlated with the level of endotoxin.CONCLUSION: Patients with AAD are often accompanied by systemic inflammatory responses, with inflammation-related cytokines (IL-6, TNF-alpha, CRP and MMP-9) and endotoxins levels significantly elevated. Combined monitoring of dynamic changes in inflammatory cytokines and endotoxins, as well as early interventions, has important clinical implications for evaluating the prognosis of AAD and reducing mortality.
