polycythemia criteria for phlebotomy

A reduced serum erythropoietin (EPO) level is the only minor diagnostic criterion that has been retained in the 2016 WHO criteria. 2013;27(9):1874-1881. 2011;117(10):2813-2816. A retrospective analysis of 248,839 patients with presumptively normal complete blood cell count results showed that 6.48% of the males had hemoglobin levels above 16.5 g/dL or hematocrit levels above 49%, whereas 0.28% of the females had hemoglobin levels above 16.0 g/dL or hematocrit levels above 48%.22 In patients with borderline hemoglobin levels, it is therefore important to assess carefully for possible causes of secondary polycythemia and perform a diagnostic workup for PV in the presence of clinical features (eg, pruritus, splenomegaly, previous thrombosis) and/or laboratory features (eg, leukocytosis, thrombocytosis) associated with MPN. Quintás-Cardama A, Kantarjian H, Manshouri T, et al. Passamonti F. Prognostic factors and models in polycythemia vera, essential thrombocythemia, and primary myelofibrosis. In this therapy, your doctor removes blood from your vein. Gisslinger H, Klade C, Georgiev P, et al. The most recent update to the World Health Organization diagnostic criteria for PV was published in 2016. Basically, doctors must consider the revised WHO diagnostic criteria in light of the new cutoffs for hemoglobin level and hematocrit. 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). Am J Hematol. A follow-up study. 63. Leuk Lymphoma. An increase in the number of white blood cells does not usually cause noticeable signs or symptoms but can predict a higher risk of clot formation. An effective response is defined by control of the platelet count, a white cell count that normalizes, minimal use of phlebotomy, and, if present, resolution of splenomegaly after treatment with a maximum tolerated dose given up to 3 months. Barosi G, Birgegard G, Finazzi G, et al. Approximately 20% of patients with PV have grade 1 bone marrow reticulin fibrosis at diagnosis, which does not necessarily imply a diagnosis of myelofibrosis but is associated with a higher risk for myelofibrosis evolution.24 A recent retrospective study that included 262 patients with PV whose disease was diagnosed according to the 2016 WHO criteria confirmed the association between bone marrow reticulin fibrosis of at least grade 1 at diagnosis (present in this study in as many as 48% of patients) and subsequent fibrotic progression.25 It should be noted that the presenting clinical and laboratory features did not differ significantly between patients with and without bone marrow fibrosis. 57. Phlebotomy treats polycythemia vera in two ways: by decreasing the number of blood cells by physically removing them from the body and by causing an iron deficiency that limits new red blood cell production. PPV-MF is currently diagnosed according to the 2008 International Working Group-Myeloproliferative Neoplasms Research and Treatment (IWG-MRT) Criteria (Table 2),39 with histopathology clearly playing a prominent role. A complementary method, because patients with polycythemia vera are at increased risk of blood clots, is also low-dose aspirin therapy. Blood. The goal of treating secondary polycythemia is to control its underlying cause, if possible. This tool does not provide medical advice. 2016;37(10):876-880. A progressive increase in the leukocyte count is considered a criterion to initiate cytoreductive treatment, and actionable cardiovascular risk factors should be managed to ameliorate the patient’s risk profile.33,53,54 Thrombocytosis (platelet count >1000 × 109/L) constitutes a risk factor. Efficacy of pipobroman in the treatment of polycythemia vera: long-term results in 163 patients. Major criteria. 15. Verstovsek S, Vannucchi AM, Griesshammer M, et al. Leukemia. Passamonti F, Maffioli M. Update from the latest WHO classification of MPNs: a user’s manual. A phlebotomy is often the first treatment for polycythemia vera. 2. 2009;113(13):2895-2901. Overall hematologic response was excellent (95%), although 24% of patients discontinued pegylated interferon because of toxicity. It's a lot like donating blood. 13. Treatment with phlebotomy or hydroxyurea was associated with lower mortality among older patients with polycythemia vera (PV) who were considered at high thrombotic risk, compared with patients who received neither treatment, according to results from a population-based cohort study published in Blood Advances.Each treatment also lowered risks of … Major criteria remain JAK2 positivity and increased red cell volume, but Cr-51 RCM is mandatory for patients who do not meet the defined elevated hemoglobin or hematocrit value (>18.5 g/dL and 60% in men and >16.5 g/dL and 56% in women, respectively). 65. 2009;27(32):5418-5424. Phlebotomy is often the first treatment for polycythemia vera. Passamonti F, Brusamolino E, Lazzarino M, et al. 2016;101(10):e405-e406. Polycythemia vera may not cause any signs or symptoms in its early stages. You'll usually feel better, too. Quintás-Cardama A, Abdel-Wahab O, Manshouri T, et al. Blood. Polycythemia vera (PV), essential thrombocythemia (ET), and primary myelofibrosis (PMF) constitute the so-called classic Philadelphia chromosome–negative chronic myeloproliferative neoplasms (MPNs).1-4 PV is characterized by erythrocytosis and, in approximately 40% of patients, some degree of leukocytosis and thrombocytosis. Therapeutic phlebotomy is used to remove excess iron and maintain low normal body iron stores in patients with hemochromatosis. Leukemic transformation of polycythemia vera: a single center study of 23 patients. © 2005 - 2019 WebMD LLC. 2008;111(3):1686-1689. 64 Recently, a Spanish study provided the size of this condition: overall, the criteria for hydroxyurea intolerance or resistance were found in 15% of 890 patients with PV. Polycythemia refers to an increased hemoglobin concentration and/or hematocrit in peripheral blood. Changing incidence of myeloproliferative neoplasms: trends and subgroup risk profiles in the USA, 1973-2011. J Clin Oncol. The effect of arterial hypertension on thrombosis in low-risk polycythemia vera. Int J Lab Hematol. World Health Organization 2016 polycythemia vera diagnostic criteria16. Drs Maffioli and Mora are hematologists in the hematology department at ASST Sette Laghi - Ospedale di Circolo in Varese, Italy. Leukocytosis as a major thrombotic risk factor in patients with polycythemia vera. Am J Hematol. 54. Some clinicians will aim for more stringent hematocrit control—for example, below 45%—whereas others who are satisfied with a more “relaxed” approach will seek hematocrit values between 45% and 50%, or even below 52%.
