Patients can present with arterial or venous vascular occlusive events, microvascular disturbances or, occasionally, haemorrhage. 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.

Thrombosis accounts for the majority of morbidity and mortality. New York: Churchill Livingstone, 2000:1130–55. The resultant hyperviscosity of the blood predisposes such patients to thrombosis. The Polycythemia Vera Study Group (PVSG) was the first to set rigorous criteria for the diagnosis of polycythemia vera (PV) in the 1970s. Barosi G, Mesa R, Thiele J, et al.

Finally, EEC growth is based on the ability of erythroid cells from peripheral blood and bone marrow samples in PV to grow in vitro without the addition of EPO.12,13 This unique finding, along with serum EPO levels, forms the basis for a new diagnostic approach,5 but has the disadvantages of expense and limited availability.10. Semin Thromb Hemost. Treatment of polycythemia vera. 3d ed. Inapparent polycythemia vera: an unrecognized diagnosis. Because PV is an autonomous (i.e., EPO-independent) erythroid proliferation, serum EPO levels in PV are low or normal.1,5 Low-serum EPO levels for PV have a sensitivity of 70 percent and a specificity of 90 percent.1.

Therapeutic recommendations for polycythemia vera. They also often have: This procedure is used to measure the volume (amount) of red blood cells in relation to the volume of plasma (fluid) in whole blood. The median age of patients diagnosed with PV is 60 years, although it can occur in persons in all age groups.1 PV occurs with a slight predominance in men. Polycythemia vera is a chronic myeloproliferative disorder characterized by increased red blood cell mass. Concern regarding the safety of long-term use of hydroxyurea has been noted.14,19, Recombinant interferon alfa-2b reduces myeloproliferation and splenomegaly, and alleviates the symptom of pruritus.23 It has no established mutagenic potential, and thus may prove a valuable option for younger patients and those with impressive splenomegaly.19 A small case series of 11 patients found that the patients’ red cell indices could be normalized over six to 12 months with interferon therapy alone, and without evidence of thrombosis.24 However, many patients discontinue interferon because of side effects, and the cost of treatment is high.23,25  Myelosuppressive treatment options are summarized in Table 4.1,26,27, Reduction of platelet counts with anagrelide has been proposed as a treatment option for PV, as with other myeloproliferative disorders, but this option has not been thoroughly studied.19,25 Targeting platelet function with aspirin remains another possibility.

Patients may present with complaints of pruritus after bathing, burning pains in the distal extremities (erythromelalgia), gastrointestinal disturbances, or nonspecific complaints such as weakness, headaches, or dizziness. However, this effect disappeared after three years, and rates of thrombosis thereafter were equivalent.8,14,19 Unfortunately, prospective data have revealed the mutagenic potential of myelosuppressive agents such as 32P, with a relative risk for malignancy of 2.3 to four times that of the control groups after about six years of treatment.

Diagnosis of PV requires meeting either all 3 major criteria, or the first 2 major criteria and the minor criterion a JAK, Janus-associated kinase. Comparisons may be useful for a differential diagnosis. In addition to interferon alfa-2b (Intron A) therapy, agents that target platelet number (e.g., anagrelide [Agrylin]), and platelet function (e.g., aspirin) are being investigated as potential therapies. Interferon alpha-2b: a new treatment for polycythemia vera. Individuals with PV usually have very low levels of erythropoietin. People with PV have high red blood cell counts. 21. Berlin NI, 16.

A risk-stratified approach to the management of PV is currently recommended (Table 5).1 [Level of evidence: C, expert opinion] Patients treated with phlebotomy alone benefit from low rates of malignancy but experience more thrombosis events during the first few years of treatment. Fruchtman SM, Wasserman LR. Chicago: ASCP Press, 2000:121. Other features that may be seen in polycythemia vera include a low ESR and a raised leukocyte alkaline phosphatase. Symptoms such as transient neurologic disturbances may respond to low-dose aspirin therapy. 22. : Proposed criteria for the diagnosis of post-polycythemia vera and post-essential thrombocythemia myelofibrosis: a consensus statement from the International Working Group for Myelofibrosis Research and Treatment. Furthermore, the GISP found an added independent dimension to the risk of thrombosis—rates increase with age and a history of thrombotic events.20 Despite these concerns, a recent survey of physicians who were members of the American Society of Hematology showed that 69 percent use phlebotomy as first-line therapy for PV.21, Platelet count lower than 150,000 per mm3 (1,500 × 109 per L), Platelet count higher than 150,000 per mm3. Furthermore, neither of these criteria is sensitive nor specific.1 Nonetheless, the PVSG criteria remain the diagnostic standard. 1998;83:143–9.
