The use of intravenous gammaglobulin in dengue fever, a case report.

We managed a serologically documented case of dengue fever with thrombocytopenia with IV IgG. Acute and convalescent ELISA and HI titers indicated an acute dengue infection with a secondary response that clinically, and by laboratory parameters dramatically improved after IV IgG administration. The use of IV IgG in cases of thrombocytopenia associated with dengue has both theoretical advantages and disadvantages. IV IgG may have a role in the management of DHF/DSS because of the significant morbidity and mortality associated with DHF/DSS. A prospective randomized study should be developed to determine if IV IgG does indeed effect the course of thrombocytopenia in dengue infections.
