How is MYH9-related thrombocytopenia (MYH9RD) treated?

There is currently no cure for MYH9-related thrombocytopenia. Measures that can be taken to prevent bleeding episodes may include platelet transfusion, desmopressin, or antifibrinolytic drug administration prior to surgery or invasive procedures, and regular dental care to prevent bleeding of the gums. People with MYH9RD should avoid drugs that inhibit platelet function or blood coagulation, activities with high risk for injury, ototoxic drugs, hazardous noise, nephrotoxic agents (agents that are toxic to the kidneys), glucocorticoids (steroids) and radiation therapy. Bleeding episodes are treated with platelet transfusion and sometimes with desmopressin (this helps to shorten bleeding time in some people). People with bleeding episodes should be monitored for anemia. Once a year urine analysis (including 2-hour protein) and a measurement of serum concentration of creatinine should be done to monitor for kidney disease. Hearing and vision evaluations are needed every three years prior to onset of hearing loss and cataracts. Kidney complications, hearing loss, and cataracts are all managed in a standard fashion.[1]
