Answer

Blood Products

Blood products are used to improve clinical and immunologic aspects of ITP. These products may decrease autoantibody production and increase solubilization and removal of immune complexes.

IV RhIG (WinRho SDF)

Specialized immunoglobulin product manufactured from pools of plasma from Rh(D)-negative persons and alloimmunized to D blood group antigen. Subjected to anion-exchange column chromatography to permit IV infusion and solvent-detergent treatment and nanofiltration to reduce infectivity by lipid-enveloped viruses. Induces immune RBC hemolysis in Rh(D)-positive recipients, decreasing function of mononuclear macrophages (reticuloendothelial blockade) and sparing immunoglobulin-coated platelets from splenic destruction.

IVIG (Gamimune, Gammagard, Sandoglobulin)

Large dose of 1 g/kg induces decreased function of mononuclear macrophages (reticuloendothelial blockade), sparing immunoglobulin-coated platelets from splenic destruction. Used with IV methylprednisolone to manage acute ITP in children. Decreased time to an increased platelet count compared with IV RhIG, but the difference does not appear to be clinically significant. Compared with IV RhIG, associated with more adverse effects, longer infusions, and increased cost, causing many hematologists to prefer IV RhIG as a supplement to corticosteroids, at least for Rh(D)-positive patients.
