Correlation of IFN-inducible protein 10 levels in Sera with disease severity and clinical outcome of the dengue patients

Dengue Virus (DV) infection may cause life-threatening Dengue Hemorrhagic Fever (DHF) and Dengue Shock Syndrome (DSS). Although many cytokines involved in the pathogenesis of DHF/DSS have been reported, the expression status of IFN-inducible protein-10 (IP-10) in dengue patients is still unknown. This is the first report to unravel that IP-10 level was significantly elevated in the sera of Dengue Fever (DF) patients. However, the level declined while the disease proceeds to severe DHF/DSS, which is different from the expression profiles of other DV related cytokines in the patients. IP-10 may be used to monitor the severity of dengue disease.
