In oncology, polycythemia vera (PV) is an uncommon myeloproliferative neoplasm in which the bone marrow makes too many red blood cells. [1] The majority of cases [ 2 ] are caused by mutations in the JAK2 gene, most commonly resulting in a single amino acid change in its protein product from valine to phenylalanine at position 617.
Mild polycythemia on its own is often asymptomatic. Treatment for polycythemia varies, and typically involves treating its underlying cause. [6] Treatment of primary polycythemia (see polycythemia vera) could involve phlebotomy, antiplatelet therapy to reduce risk of blood clots, and additional cytoreductive therapy to reduce the number of red ...
High platelet counts can occur in patients with polycythemia vera (high red blood cell counts), and is an additional risk factor for complications. [citation needed] A very small number of people report symptoms of erythromelalgia, a burning sensation and redness of the extremities that resolves with cooling, or aspirin or both. [3]
Diseases Database coding number Medical Subject Headings Iron-deficiency anemia: D50: 6947: Iron-deficiency anemia (or iron deficiency anaemia) is a common anemia that occurs when iron loss (often from intestinal bleeding or menses) occurs, and/or the dietary intake or absorption of iron is insufficient. In such a state, hemoglobin, which ...
However, splenectomy in the presence of massive splenomegaly is a high-risk procedure, with a mortality risk as high as 3% in some studies. [23] In November 2011, the US Food and Drug Administration (FDA) approved ruxolitinib (Jakafi) as a treatment for intermediate or high-risk myelofibrosis. [24] [25] Ruxolitinib serves as an inhibitor of JAK ...

No evidence of polycythemia vera. hematocrit < midpoint of normal range or normal red cell mass in presence of normal iron stores; B4.
Causes: Chronic myeloid leukemia, polycythemia vera, primary myelofibrosis, essential thrombocythemia, acute myeloid leukemia, allergic reactions or chronic inflammation related to infections, inflammatory bowel disease, and autoimmune disease. Diagnostic method: Complete blood count and blood smear.
Hematologic diseases are disorders which primarily affect the blood and blood-forming organs. Hematologic diseases include rare genetic disorders, anemia , HIV , sickle cell disease and complications from chemotherapy or transfusions.
