The kinetics of dengue virus (DEN)-specific serum
immunoglobulin classes (immunoglobulin M [IgM] and IgA) and
subclasses (IgG1 to IgG4) were studied in patients suffering from
dengue fever (DF), dengue hemorrhagic fever (DHF), and dengue shock
syndrome (DSS). Serum samples from non-DEN febrile patients were
included as controls. IgM, IgG1, and IgG3 serum antibodies were the
predominant immunoglobulins throughout the course of illness in all
three patient groups. In contrast, IgA antibodies were significantly higher in the acute phase in DSS patients compared to those in DF
patients (P < 0.05). The levels of IgG1 differed
significantly between patients with DF and those with DHF and DSS
(P < 0.05). A significant difference was also found
in IgG3 levels between DF patients and DHF patients (P < 0.05) but not between DF patients and DSS patients. Finally, levels
of IgG4 antibodies differed significantly between DF patients and DSS
patients (P < 0.05). Collectively, these data show
that increased levels of DEN-specific IgA, IgG1, and IgG4 serum
antibodies are risk markers for the development of DHF and DSS and that
their measurement may provide valuable guidance for early therapeutic intervention.
