摘要
The vascular leakage was shown by the increment of hematocrit (Hct), dengue viral infected monocyte, monocyte status, and cytokines production in patients infected with dengue virus. Dengue viral antigens were demonstrated in monocytes (CD14+) fromperipheral blood mononuclear cells. The increased levels of Hct, interleukin-(IL-) 10, and tumor necrosis factor-alpha (TNF-alpha) were detected in dengue fever (DF), dengue hemorrhagic fever (DHF) and dengue shock syndrome (DSS) patients as compared with other febrile illnesses (OFIs). The highest levels of Hct and IL-10 were detected in DSS patients as compared with other groups (P < 0.05) especially on one day before and after defervescence. The unstimulated and lipopolysaccharide-(LPS-) stimulated monocytes from DSS patients showed the significantly decreased of intracellular IL-1 beta and TNF-alpha In addition, the lowest level of mean fluorescence intensity (MFI) of CD11b expression on monocytes surface in DSS patients was also demonstrated. Furthermore, the negative correlations between IL-10 levels and intracellular IL-1 beta and MFI of CD11b expression in unstimulated and LPSstimulated monocytes were also detected. Nevertheless, not only were the relationships between the prominent IL-10 and the suppression of intracellular monocyte secretion, namely, IL-1 beta, TNF-alpha, demonstrated but also the effect of vascular leakage was observed.
