Abstract:
Objective:To compare the levels of cytokines in patients with dengue fever (DF) and severe dengue (SD) at different time points during the course of disease, to seek the cytokines that can be used as early warning signs of SD, and to explore the relationship between the immune response and the pathogenesis of SD.Methods:Plasma samples at different time points were collected from 60 hospitalized patients including 48 mild cases and 12 severe cases in Guangzhou Eighth People′s Hospital during June to December, 2014. Levels of 19 cytokines including TNF-α, IL-6, IL-8, IL-10, IL-15, IL-17A, IFN-α2, IP-10, MCP-1, RANTES, GRO-α, PDGF-AA, PDGF-AB/BB, MIF, VEGF, sVCAM-1, sICAM-1, sFas and sFasL were determined by a multiplex Luminex system.The viral loads were determined by using fluorescence quantitative RT-PCR and the correlation between viral loads and cytokine level were analyzed.Results:The levels of TNF-α, IL-6, IL-8, IL-10, IL-15, IFN-α2, IP-10, MCP-1 and sVCAM-1 increased in dengue patients, while RANTES, GRO-α and PDGF decreased.The levels of IL-17A, MIF, VEGF, sICAM-1, sFas and sFasL did not change. The levels of TNF-α, IL-6, IFN-α2, IP-10 and sVCAM-1 in SD patients were significantly higher than those in DF patients at the early stage (Day 2-5 after disease onset), and the differences were statistically significant. On day 6-10, the levels of TNF-α, IL-6, IL-8, IL-10, IL-15, PDGF, RANTES, IFN-α2, IP-10 and sVCAM-1 were significantly different between DF and SD patients. The results of correlation analysis showed that the level of IL-15 was moderately correlated with viral load, while other cytokines was only weakly correlated or not.Conclusions:TNF-α, IL-6, IFN-α2, IP-10 and sVCAM-1 can be used as early warning signs of SD. The level of cytokines is related to the severity of dengue fever.
