Primary polycythaemia vera in the elderly.
At presentation the history of an 87-year-old woman included progressive memory loss, repeated transient ischaemic attack, increasing fatigue, dizziness, palpitations and frequent falls. Investigations revealed erythrocytosis, leukocytosis, thrombocytosis, normal arterial oxygen concentration and an increased red cell volume. Polycythaemia vera was diagnosed and was successfully managed by phlebotomy with half a unit twice a week and rechecks of her haematocrit, initially; she reported marked improvement after 2 weeks of treatment. The alternative treatments for polycythaemia vera are discussed; in addition to venesection, conventional treatments include bone-marrow depressive agents such as phosphorus-32 and chemotherapy with agents such as hydroxyurea. More recent developments include isovolumic erythrocytophoresis, alpha-interferon and ticlopidine. All of the treatments are associated with complications, or other disadvantages, thrombotic complications in the case of phlebotomy, malignancies in the case of most myelosuppressive treatments, and problems of compliance in others. The optimal treatment for polycythaemia vera is a judicious combination of the alternatives, depending on the phase of the disease, the age of the patient, and other prognostic factors.
