The authors indicate that they do not have any conflicts of interest. Saunders, 1995:166–94. 5. Individuals with PV usually have very low levels of erythropoietin. An algorithm summarizing the evaluation and management of PV is presented in Figure 1. Berk PD, Wasserman LR, Fruchtman SM, Goldberg JD. Berk PD, Wasserman LR, Fruchtman SM, Goldberg JD. The use of myelosuppressive agents such as radioactive phosphorus (32P), chlorambucil (Leukeran), busulfan (Myleran), pipobroman (Vercyte), and hydroxyurea (Hydrea) in conjunction with phlebotomy has been studied. Lamy T, Diagnosis is made using criteria developed by the Polycythemia Vera Study Group; major criteria include elevated red blood cell mass, normal oxygen saturation, and palpable splenomegaly. Therefore, a typical family physician can expect to make a diagnosis of PV once or twice during his or her career, and will often have at least one patient in his or her patient panel who carries the diagnosis. Semin Hematol. Patients in this group stand to gain from the benefit of lower early thrombosis rates with myelosuppressive medications. Murphy S. However, because of a paucity of centers doing red bloo… Polycythemia vera (PV) is the commonest myeloproliferative neoplasm (MPN), the ultimate phenotypic consequence of JAK2 somatic driver mutations, and the MPN most often complicated by arterial and venous thrombosis because it is the only one in which erythrocytosis occurs. Tefferi A. 1997;102:14–20.

A. Hemoglobin level 1.1. Interferon alpha-2b: a new treatment for polycythemia vera. PV produces microvascular sequelae whose symptoms, while not life threatening, can be bothersome to patients (Table 1).1,4  Because PV is rare, high-quality evidence supporting treatment is lacking. Address correspondence to Brian J. Stuart, M.D., Naval Hospital Jacksonville, Family Practice Department, 2080 Child St., Jacksonville, FL 32214 (e-mail: The authors indicate that they do not have any conflicts of interest. However, palpation is only 58 percent sensitive for diagnosis11 (i.e., if present, it will not be detected by examiners in 42 percent of cases). Ann Hematol. 22. A pathologist examines the sample to see if there are any unusual changes in the size, shape and appearance of various blood cells. Polycythemia vera is a chronic condition that can't be cured. Berk PD, Although serum EPO levels and marrow biopsies may become a routine diagnostic option, the PVSG criteria remain the standard of diagnosis. Updated diagnostic criteria include the bone marrow findings as a major criterion for diagnosis, unless the hemoglobin is greater than 18.5 g/dl. Get Permissions, Access the latest issue of American Family Physician. Your doctor may examine your bone marrow even though the test isn't needed to diagnose PV. Treatment of polycythemia vera. While a person may have certain signs and symptoms of polycythemia vera (PV), laboratory tests are needed to confirm the diagnosis.

Learn about PAD symptoms such as leg and foot pain, complications, treatment for PAD, and NHLBI research and clinical trials. Review the check marks in each column and compare the result against the totals required to meet WHO guidelines for diagnosis of each myeloproliferative neoplasm (MPN). Patients treated with phlebotomy alone had the same rate of cancer as patients in the control groups.2,14,20, The nonalkylating myelosuppressive agent hydroxyurea is widely used in the treatment of PV, because it is less leukemogenic.22 PVSG data have established this agent to be an effective bone marrow suppressant. The major goal of treatment is to prevent thrombotic events. Barkun AN, 14. It also measures the amount of the iron-rich protein that carries oxygen in red blood cells and the percent of whole blood made up of red blood cells (the hematocrit). Current management in polycythemia vera. 3d ed. Want to use this article elsewhere? Wasserman LR. Contact USP DI drug information for the healthcare professional. There are three groups of early stage MPN, U: 1) Early stages of polycythemia vera, primary myelofibrosis, or essential thrombocythemia in which the characteristic features are not yet fully developed.

Pruritus in polycythaemia vera: prevalence, laboratory correlates and management. Chlorambucil, busulfan, and pipobroman, all alkylating agents, have fallen out of favor because of concerns about rates of iatrogenic leukemia.19 The agent 32P remains in use with supplemental phlebotomy and has a reported median survival similar to that of phlebotomy alone—10.9 years according to PVSG data14 and 11.8 years according to GISP.20 The myelosuppressive drugs such as 32P had an initial advantage over phlebotomy alone regarding thrombosis rates during the first three years of treatment. Treatment focuses on reducing your amount of blood cells. A procedure in which a blood sample is viewed under a microscope. 4. 1989;13:331–8. Proliferation of mature megakaryocytes that vary in size and shape. People with PV have high red blood cell counts. A diagnosis of polycythemia vera (PV) requires the presence of either all 3 major criteria, or the first 2 major criteria plus the minor criterion. Barosi G, Therapeutic recommendations for polycythemia vera. 18. Leuk Lymphoma. Treatment includes phlebotomy with the possible addition of myelosuppressive agents based on a risk-stratified approach. Finazzi G, In many cases, treatment can reduce the risk of complications from polycythemia vera and ease signs and symptoms.Treatment might include: 1. During the physical examination, the doctor may: This test measures the number of red blood cells, white blood cells and platelets in a sample of blood. Guest editor of the series is Anthony J. Viera, LCDR, MC, USNR. In: Wasserman LR, Berk PD, Berlin NI, eds. 2014; 7 (7 Suppl 3): p.S36-47. A number of new therapeutic agents have been developed. Polycythemia vera: diagnosis and treatment 2002. Other signs and symptoms are listed in Table 1.1,4, In making the diagnosis of PV, the physician must first exclude a secondary erythrocytosis.5,6  Once a secondary cause is ruled out (Table 27), the diagnosis of PV is made using a combination of major and minor criteria defined by the Polycythemia Vera Study Group (PVSG). Worsley A, Grulois I, 2002;99:1144–9. Polycythemia vera is a chronic myeloproliferative disorder characterized by increased red blood cell mass. This lack of sensitivity has led to some discussion about the use of imaging techniques to answer the question, although such a finding by imaging might be relegated to the status of a minor criterion.10 In addition, the minor criteria of leukocyte alkaline phosphatase (LAP) and serum vitamin B12 and B12 binding capacity may be dropped in the future because of inter-laboratory error regarding LAP and the unavailability of vitamin 10 B12 binding capacity. Eligible patients were randomly allocated (1:1) to receive either phlebotomy and low-dose aspirin (standard group) or ropeginterferon alfa-2b on top of the standard treatment (experimental group). If the antibody is present at a high level, it may also suggest that there is a higher risk of severe joint damage.

Major diagnostic criteria include increased RCM, normal oxygen saturation, and the presence of splenomegaly. The previous guideline was published in 2005 (McMullin et al, 2005) with an amendment in 2007 (McMullin et al, 2007) to update the diagnostic criteria following the discovery of the JAK 2 mutation in patients with polycythaemia vera … Polycythemia vera (PV) is a chronic myeloproliferative disorder characterized by an increased red blood cell mass (RCM), or erythrocytosis, which leads to hyperviscosity and an increased risk of thrombosis. Sign up for the free AFP email table of contents. Elevated levels of hemoglobin 1.1.1. Berlin NI, Don't miss a single issue. The International Council for Standardization in Haematology (ICSH) has amended the RCM assessment, recommending the use of formulas incorporating body surface area, weight, gender, and plasma volume.8–10 [Level of evidence: C, consensus opinion] A patient with PV could have low oxygen saturation levels, because it is possible to have both PV and an unrelated hypoxic disorder.1 Palpable splenomegaly is an important physical finding and major criterion.

Polycythemia vera is the most common of the myeloproliferative neoplasms; its incidence in the United States is estimated to be 1.9/100,000, with incidence increasing with age. One PVSG protocol found that 300 mg of aspirin daily in conjunction with phlebotomy and dipyridamole (Persantine) was associated with an increased risk of gastrointestinal bleeding.14 However, a small GISP study randomized patients to low-dose aspirin (40 mg per day) or placebo and found no increased rates of bleeding or complications.1 The use of low-dose aspirin is being investigated by the European Collaboration on Low-Dose Aspirin.19,22,25.
