The defined antigen substrate sphere system is a simple method for detecting antigen or antibody in the circulation. The technic is based on the coupling of antigen or antibody with Sepharose 4B beads that have been activated by cyanogen bromide. In this study the activated beads were exposed to dengue antigen in the serum from a patient with dengue hemorrhagic fever and then stained with antidengue antibody conjugated with horseradish peroxidase. The positive reaction showed brown beads by light microscopy, whereas the negative reaction gave colorless beads. The authors examined 134 specimens from 91 cases. The results were positive in 53.85%. The dengue antigen appeared in the sera on the day before shock or subsidence of fever. The percentages of sera containing soluble dengue antigen were greatest on the day of shock or subsidence of fever (33.33%) and on the fifth day of fever (28.07%). The highest titers of soluble dengue antigen (1:40 to 1:80) appeared in the sera of patients who had Grade III disease on the day of shock. The dengue antigen appeared most often in sera that had high titers of dengue antibody. It is postulated that this detected dengue antigen may be a part of soluble immune complexes formed during the hyperimmune stage of the immune response, and plays a significant role in the pathogenesis of dengue hemorrhagic fever and shock syndrome.
