Which therapies are used to treat hyperviscosity syndrome?

• A. IV fluids, antibiotics
• B. IV resuscitation, plasmapheresis, leukopheresis, phlebotomy
• C. Chemotherapy and radiation
• D. Immunotherapy and steroids

Answer: (B)

Hyperviscosity syndrome needs rapid reduction of the factors making the blood thick so microcirculation can improve quickly. The most effective acute therapy is plasmapheresis, which directly removes excess circulating immunoglobulins (often IgM) from the plasma and replaces it with a lighter solution. This immediate drop in viscosity typically leads to swift improvement in neurologic and visual symptoms, mucosal bleeding, and perfusion. Supporting measures include giving IV fluids to keep the intravascular volume adequate, which helps maintain organ perfusion during the procedure. If the viscosity problem is driven by a very high white blood cell count, leukapheresis can rapidly lower the leukocyte burden and relieve leukostasis. In cases where viscosity is worsened by a high hematocrit, phlebotomy can help reduce red blood cell mass and thus viscosity. Other treatments like antibiotics, chemotherapy, radiation, immunotherapy, or steroids do not address the immediate cause of the thick blood and do not reverse the symptoms promptly enough in an acute setting, which is why they are not the preferred rapid-acting therapies for this condition.
