  https://www.ncbi.nlm.nih.gov/books/NBK557660/

  Polycythemia vera (PV) is a myeloproliferative neoplastic disorder involving uncontrolled red blood cell production resulting in elevated red blood cell (RBC) mass. There is often a concurrent stimulation of myeloid and megakaryocytic lineages, leading to increased white blood cell and platelet production. Signs and symptoms, including headache, dizziness, claudication, thrombosis, are a consequence of increased blood viscosity. […] Symptoms of polycythemia vera (PV) are related to hyperviscosity and thrombosis, impairing oxygen delivery. Physical complaints can include fatigue, headache, dizziness, tinnitus, vision changes, insomnia, claudication, pruritus, gastritis, and early satiety. Aquagenic pruritus, which occurs during or after a hot shower, is a complaint in 40% of patients. […] The average survival of untreated polycythemia vera (PV) is 18 months, whereas median survival is 14 years overall and 24 years if younger than 60 for those undergoing treatment. […] Polycythemia vera-related complications and mortality are related to thrombosis, hemorrhage, peptic ulcer disease, myelofibrosis, acute leukemia, or myelodysplastic syndrome (MDS).

• #2 Polycythemia vera – Wikipedia

  https://en.wikipedia.org/wiki/Polycythemia_vera

  In oncology, polycythemia vera (PV) is an uncommon myeloproliferative neoplasm in which the bone marrow makes too many red blood cells. Most of the health concerns associated with polycythemia vera are caused by the blood being thicker as a result of the increased red blood cells. It is more common in the elderly and may be symptomatic or asymptomatic. Common signs and symptoms include itching (pruritus), and severe burning pain in the hands or feet that is usually accompanied by a reddish or bluish coloration of the skin. Patients with polycythemia vera are more likely to have gouty arthritis. […] People with polycythemia vera can be asymptomatic. Clinical symptoms of polycythemia vera are mostly due to hyperviscosity of blood. A classic symptom of polycythemia vera is pruritus or itching, particularly after exposure to warm water (such as when taking a bath), which may be due to abnormal histamine release or prostaglandin production. Such itching is present in approximately 40% of patients with polycythemia vera. Gouty arthritis may be present in up to 20% of patients. Peptic ulcer disease is also common in patients with polycythemia vera; most likely due to increased histamine from mast cells, but may be related to an increased susceptibility to infection with the ulcer-causing bacterium H. pylori.

• #3 Polycythemia Vera: What It Is, Symptoms & Treatment

  https://my.clevelandclinic.org/health/diseases/17742-polycythemia-vera

  Polycythemia vera is a type of chronic leukemia (blood cancer) that causes your bone marrow to produce too many red blood cells. It progresses very slowly and often isnt diagnosed until after the age of 60. Most people manage symptoms well for many years. The biggest risk from too many red blood cells is blood clots. […] Polycythemia vera causes your body to produce too many red blood cells. Extra blood cells increase your likelihood of bleeding, bruising and clotting. They thicken your blood and slow your circulation, which means your blood carries less oxygen to your bodys tissues and organs than they need. They also overwork your spleen, which is responsible for filtering your blood and clearing out old blood cells. This can lead it to become swollen and sore (splenomegaly). Over time, you may develop a variety of uncomfortable symptoms as a result of your condition. PV can also lead to several secondary conditions.

  Polycythemia vera (PV) is a rare disorder that affects blood cell and platelet production. The early stages of polycythemia vera often cause nonspecific symptoms, but advanced stages can lead to myelofibrosis and other severe complications. […] Symptoms of PV tend to develop gradually over years. […] In the early stages, the condition may cause no apparent symptoms. A healthcare professional may diagnose it following a routine blood test before any symptoms develop. […] As time passes, more noticeable symptoms may occur. The disease may also cause complications, such as an enlarged spleen, chest pain, a heart attack, or a stroke. […] A person may not have noticeable symptoms in the early stages of PV. Any symptoms that appear are often nonspecific. […] For example, early symptoms may include fatigue, weakness, dizziness, headache, unusual sweating, particularly at night, itchy skin, which may get worse after a warm bath or shower.

  Polycythemia vera (PV) is a chronic blood cancer. This means it lasts a long time and may never go away. Some people with PV may not have symptoms. Others have severe symptoms that interfere with their daily lives. PV is a progressive disease, so it may change or get worse with time. Changes in your symptoms may be a possible sign of disease progression. […] Because PV is a progressive condition, it can change over time. That means that some of the signs and symptoms may change as well. This is why its important to take an active role in monitoring your PV over time. […] According to the MPN Landmark Survey, 66% of patients with PV reported that their symptoms reduced their quality of life. […] Careful symptom tracking provides a number of valuable insights. Not only does it help identify trends within your health, but it can also help you and your Healthcare Professional better understand how to manage and adjust your care over time.

• #6 Erythrocytosis

  https://www.nhs.uk/conditions/erythrocytosis/

  Most cases develop later in life. The average age at diagnosis is 60. […] Treatment for erythrocytosis aims to prevent symptoms and complications (such as blood clots), and treat any underlying causes. […] Venesection is the simplest and quickest way of reducing the number of red cells in your blood. […] In cases of polycythaemia vera, medicine may be prescribed to slow down the production of red blood cells. […] If you have polycythaemia vera, daily low-dose aspirin tablets may be prescribed to help prevent blood clots and reduce the risk of serious complications. […] The outlook for erythrocytosis largely depends on the underlying cause. […] However, some cases particularly cases of polycythaemia vera can be more serious and require long-term treatment. […] However, people with polycythaemia vera can have a slightly lower life expectancy than normal due to the increased risk of problems, such as heart attacks and strokes. […] Polycythaemia vera can also sometimes cause scarring of the bone marrow (myelofibrosis), which can eventually lead to you having too few blood cells. In some rare cases, it can develop into a type of cancer called acute myeloid leukaemia (AML).

  Polycythemia vera is one of three stem-cellderived myeloid malignancies commonly known as myeloproliferative neoplasms. It is characterized by erythrocytosis, often with associated leukocytosis and thrombocytosis. It has a significant negative impact on overall mortality and morbidity in the form of arterial and venous clots, symptoms of fatigue and pruritus, and conversion to leukemia and myelofibrosis. […] Fatigue, insomnia, and difficulty concentrating are the most common presenting symptoms in patients with PV. […] Poor prognostic features include age older than 60 years, history of thrombosis, leukocytosis, high JAK2 burden, abnormal karyotype, and established cardiovascular risk factors such as smoking, hypertension, diabetes, obesity, and hyperlipidemia. […] Without treatment, death typically occurs within two years, mostly from thrombotic events.

  https://bloodcancer.org.uk/understanding-blood-cancer/polycythaemia-vera-pv/pv-symptoms/

  The symptoms of polycythaemia vera (PV) are caused by over-production of blood cells, in particular, red blood cells. […] In PV, blood stem cells produce too many red blood cells. Often, they also produce too many white bloods cells and platelets. […] Over-production of blood cells makes the blood thicker than normal, making it harder for the blood to flow smoothly through your blood vessels. Its this that causes most of the symptoms of PV. It can also cause your blood to clot too easily, which can cause serious problems. […] The symptoms of PV include: headaches, confusion, dizziness, blurred vision, night sweats, itching (pruritis), extreme tiredness (fatigue), unusual bleeding such as nosebleeds, bruising easily or heavy periods, red-looking eyes, red-looking skin (this may be harder to see on darker skin tones), a swollen spleen, causing a feeling of fullness or pain after eating small amounts, gout, causing pain in your joints.

  PV symptoms are different for everyone. Some common PV symptoms are listed below. People living with PV may experience one or any combination of these symptoms: Itchy skin, especially after a warm bath or shower; Numbness in the hands, feet, arms, or legs (might also be described as tingling, burning, or weakness); A feeling of fullness soon after eating (or bloating or pain in your upper left abdomen); Unusual bleeding (nosebleeds, bleeding gums); Painful swelling of one joint (often the big toe); Shortness of breath and difficulty breathing when lying down. […] Some people may also have vague symptoms. These symptoms may be related to PV, but they could also be brought on by other conditions. They include: Headache; Dizziness; Fatigue (needing to nap during the day, or not having the energy to do things you usually do); Blurred vision. For some patients, having too many blood cells makes the spleen work harder than normal. This can cause it to get larger. This is called splenomegaly (splen-o-meg-a-ly). […] If you’re living with PV, keeping your red and white blood cell and platelet counts under control is very important.

This can lead to angina (chest pain or discomfort) and heart failure. The high levels of red blood cells that PV causes can lead to stomach ulcers, gout, or kidney stones. […] Some people who have PV may develop myelofibrosis (MY-e-lo-fi-BRO-sis). This is a condition in which your bone marrow is replaced with scar tissue. Abnormal bone marrow cells may begin to grow out of control. […] This abnormal growth can lead to acute myelogenous (my-eh-LOJ-eh-nus) leukemia (AML), a cancer of the blood and bone marrow. This disease can worsen very quickly.

  https://www.healthline.com/health/blood-cell-disorders/complications-of-polycythemia-vera

  Polycythemia vera (PV) is a slow-growing blood cancer that can lead to complications such as blood clots, bleeding, and an enlarged spleen. In rare cases, it can progress to other blood cancers, which can be life threatening. […] PV causes excess red blood cell production. It can also increase the amount of white blood cells and platelets in the blood. The extra cells make the blood thicker and more likely to clot. […] PV increases the risk of acute myeloid leukemia, myelofibrosis, and myelodysplastic syndromes. These are rare but potentially serious complications. […] There is no cure for PV, but treatments are available to manage symptoms and thin the blood. This helps reduce the risk of a blood clot or the following complications: […] Deep vein thrombosis (DVT) can happen when a blood clot forms in a large, deep vein in the body. People with PV have a higher chance of getting a DVT because the blood flows more slowly and clots easier.

  https://mpnresearchfoundation.org/polycythemia-vera-pv/

  Most PV patients enjoy longevity, if they receive regular monitoring and treatment. However, in some cases, prolonged survival can be challenged by the development of other syndromes. Approximately 15% of PV patients develop myelofibrosis, a progressive bone marrow disorder that results in bone marrow scarring, severe anemia, and enlargement of the liver and spleen. This change can be heralded by the onset of anemia, or a low red blood count, as opposed to high red blood counts, and a significant increase in the size of the spleen). In a smaller number of cases, PV may progress to acute leukemia (AML). […] Additional complications that can occur with PV include arterial thromboses (heart attacks, strokes, intestinal gangrene), venous thromboses (of the portal and/or hepatic veins), or pulmonary embolism.

  PV symptoms are different for everyone. Some common PV symptoms are listed below. People living with PV may experience one or any combination of these symptoms: Itchy skin, especially after a warm bath or shower; Numbness in the hands, feet, arms, or legs (might also be described as tingling, burning, or weakness); A feeling of fullness soon after eating (or bloating or pain in your upper left abdomen); Unusual bleeding (nosebleeds, bleeding gums); Painful swelling of one joint (often the big toe); Shortness of breath and difficulty breathing when lying down. […] Some people may also have vague symptoms. These symptoms may be related to PV, but they could also be brought on by other conditions. They include: Headache; Dizziness; Fatigue (needing to nap during the day, or not having the energy to do things you usually do); Blurred vision. For some patients, having too many blood cells makes the spleen work harder than normal. This can cause it to get larger. This is called splenomegaly (splen-o-meg-a-ly). […] If you’re living with PV, keeping your red and white blood cell and platelet counts under control is very important. In addition to putting you at risk for a thrombotic event, PV can also progress to other conditions like myelofibrosis and leukemia.

  Polycythemia Vera (PV) is a chronic myeloproliferative neoplasia generating an accumulation of erythrocytes in the peripheral blood (polyglobulia). The disease is described as polysymptomatic and its typical manifestations consist of headache, dizziness, weakness, plethora, itching and splenomegaly, the last three being more suggestive. Thus, a diagnosis of polycythemia may be suspect when it cannot be explained by a secondary cause. […] Neuropsychiatric symptoms are described in the literature but are less prevalent in current clinical practice. […] The pathophysiology of psychiatric events in PV is not well established, but the proposed models consist of two mechanisms resulting from blood hyperviscosity: (1) slowed blood flow with hypoxia and (2) multiple thrombosis, small and disseminated by the Central Nervous System (CNS).

Symptoms such as fatigue, headaches, dizziness, itching, and an enlarged spleen (splenomegaly) are common. Thrombotic events, including strokes and deep vein thrombosis, become more likely due to increased blood viscosity. Timely treatment with phlebotomy, cytoreductive therapy (e.g., hydroxyurea or ruxolitinib), and lifestyle modifications can mitigate these risks. […] In a subset of patients, PV can progress to myelofibrosis, a condition characterized by bone marrow scarring (fibrosis). This leads to reduced blood cell production (cytopenias), severe anemia, and splenomegaly. Symptoms include extreme fatigue, weight loss, and night sweats. Treatment at this stage focuses on managing symptoms and complications, often using JAK inhibitors like ruxolitinib.

  Overproduction of blood cells and changes to blood flow increase the risk of serious blood clots in people with PV. This can lead to life-threatening conditions such as heart attack, stroke, or pulmonary embolism. Treatment of PV can reduce this risk while also helping to manage bothersome PV symptoms. PV can cause pregnancy complications, and women who are pregnant or considering becoming pregnant may wish to talk with their doctor about how to manage their health. […] In rare cases, PV progresses to myelofibrosis (scarring of the bone marrow) or acute myeloid leukemia (AML).

  Polycythemia vera is one of three stem-cellderived myeloid malignancies commonly known as myeloproliferative neoplasms. It is characterized by erythrocytosis, often with associated leukocytosis and thrombocytosis. It has a significant negative impact on overall mortality and morbidity in the form of arterial and venous clots, symptoms of fatigue and pruritus, and conversion to leukemia and myelofibrosis. […] Fatigue, insomnia, and difficulty concentrating are the most common presenting symptoms in patients with PV. […] Poor prognostic features include age older than 60 years, history of thrombosis, leukocytosis, high JAK2 burden, abnormal karyotype, and established cardiovascular risk factors such as smoking, hypertension, diabetes, obesity, and hyperlipidemia. […] Without treatment, death typically occurs within two years, mostly from thrombotic events.

  Data from the REVEAL study affirm elevated white blood cell counts and higher variant allele frequency as risk factors for progression in polycythemia vera. […] In addition to prior thromboembolic events, Grunwald explained that factors such as elevated white blood cell counts and higher variant allele frequency may affect a patients likelihood of developing myelofibrosis or acute myeloid leukemia (AML). […] Having a history of thrombosis is not only a risk factor for future thrombosis, but also a risk factor for disease progression to myelofibrosis and AML. […] Some of the other risk factors that we identified had been suggested in previous work, like the elevated white blood cell count and the higher variant allele frequency. […] It’s almost intuitive to me that the duration of time from diagnosis to starting on the study—the amount of time with the disease—would be a risk factor given that it takes time to progress.

  Polycythemia vera (PV) is a myeloproliferative neoplastic disorder involving uncontrolled red blood cell production resulting in elevated red blood cell (RBC) mass. There is often a concurrent stimulation of myeloid and megakaryocytic lineages, leading to increased white blood cell and platelet production. Signs and symptoms, including headache, dizziness, claudication, thrombosis, are a consequence of increased blood viscosity. […] Symptoms of polycythemia vera (PV) are related to hyperviscosity and thrombosis, impairing oxygen delivery. Physical complaints can include fatigue, headache, dizziness, tinnitus, vision changes, insomnia, claudication, pruritus, gastritis, and early satiety. Aquagenic pruritus, which occurs during or after a hot shower, is a complaint in 40% of patients. […] The average survival of untreated polycythemia vera (PV) is 18 months, whereas median survival is 14 years overall and 24 years if younger than 60 for those undergoing treatment.

  First, we have to be aware that PV is a chronic disease, and that people can live a long time with polycythemia vera. […] The definitive signs of progression are when the disease can evolve at least in 2 definitive patterns: 1 to leukemia and 1 to myelofibrosis. Progression to leukemia is when you start to see blasts or immature myeloid cells, you have to be concerned. […] The rate of transformation to myeloid fibrosis is higher and may be 20% in 10 years. What we start to see is what has been called classically as the spent phase, where the patients start to develop a change in the pattern of the disease. Instead of having high hemoglobin, they start to have anemia. They start to have change in the blood counts. Immature cells start to show up in the blood. Atypical problems of the red cells show up in the blood, and the patient may have developed a new set of symptoms. At that point you start to be concerned that the disease is switching.

  At first, you may not notice any problems. When they do show up, polycythemia vera symptoms can include: […] You may also feel pressure or fullness below your ribs on your left side. This might mean PV has enlarged your spleen, an organ that helps filter your blood. […] At the end stage, also known as the „spent phase,” of the disease, your bone marrow stops making healthy blood cells. This happens because the abnormal blood cells overtake your bone marrow, where they break down and are replaced with scar tissue. […] Too much scar tissue can prevent your bone marrow from doing its job: making healthy red blood cells. This can increase your risk of anemia. You may need blood transfusions to help make sure your body has enough healthy blood cells. The spleen can become swollen and painful during this stage and may need to be removed through surgery. […] In the final stages of polycythemia vera, your bone marrow stops producing healthy cells and is replaced with scar tissue.

  In the proliferative phase, there is a marked increase in red blood cell production, often accompanied by elevated white blood cells and platelets. Symptoms such as fatigue, headaches, dizziness, itching, and an enlarged spleen (splenomegaly) are common. Thrombotic events, including strokes and deep vein thrombosis, become more likely due to increased blood viscosity. Timely treatment with phlebotomy, cytoreductive therapy (e.g., hydroxyurea or ruxolitinib), and lifestyle modifications can mitigate these risks. […] In a subset of patients, PV can progress to myelofibrosis, a condition characterized by bone marrow scarring (fibrosis). This leads to reduced blood cell production (cytopenias), severe anemia, and splenomegaly. Symptoms include extreme fatigue, weight loss, and night sweats. Treatment at this stage focuses on managing symptoms and complications, often using JAK inhibitors like ruxolitinib.

  Polycythemia vera (PV) is a rare blood disease in which your body produces too many red blood cells (and sometimes too many white blood cells and platelets, too). Many of these abnormal cells function poorly. The high levels of blood cells make your blood thicker than normal, so blood clots can form more easily. Blood clots, or the grouping together of blood cells, clog up your arteries and veins, and can cause a heart attack or stroke. On top of that, when blood is thicker, it doesn’t move quickly enough to spread necessary oxygen throughout your body. This means your organs don’t get all the oxygen they need, which can cause serious problems, like angina (chest pain) and heart failure. […] PV is a disease that needs to be treated as soon as possible, but with the right treatment, most people with PV reach their normal life expectancy. Fortunately, there are effective treatments available that can manage the condition and keep patients from experiencing complications. However, PV doesn’t always show symptoms, so many people don’t even know they have it. Signs of PV develop slowly over many years and the disease is often discovered during routine blood tests done for other reasons.
