• #3 Why too many red cells are a problem: Nursing the polycythemia patient — Veterinary Internal Medicine Nursing

  https://www.veterinaryinternalmedicinenursing.com/blog/polycythemia

  Polycythemia, or erythrocytosis, is where excessive red cells are present in the blood. […] Patients with polycythemia require IVFT to dilute their blood and replace any fluid deficits present. […] There is a lot to think about when nursing patients with polycythemia. Our main considerations include: Fluid therapy, Phlebotomy, Nutrition, Oxygenation, Monitoring, General nursing care. […] Relative polycythemia is treated with intravenous fluid therapy – as we correct the hydration deficits we see in these patients and restore a normal circulating volume. […] Primary polycythemia is treated with regular phlebotomy. […] To treat secondary polycythemia we need to manage the underlying cause. […] Oxygen therapy may be required, particularly in patients with secondary polycythemia due to cardiac or respiratory disease.

• #4 Erythrocytosis: Too Many Red Blood Cells

  https://www.verywellhealth.com/erythrocytosis-401324

  Erythrocytosis causes too many red blood cells in the blood that are out of proportion with the other components. […] Erythrocytosis causes high levels of high levels of hematocrit and/or hemoglobin. As a result, blood is thicker and less able to travel through blood vessels and organs. […] Phlebotomy, a procedure to remove blood from a vein on a regular schedule, is often used to prevent complications with erythrocytosis. The blood is often replaced with normal saline. […] Certain lifestyle changes can help to lower cholesterol, improve blood pressure, and limit the risk of complications with erythrocytosis. […] Talk to your healthcare provider about smoking cessation and weight loss goals that can be managed with diet and exercise. […] Some complications of erythrocytosis are serious and can be life-threatening. Seek immediate medical attention if you experience: Heart-related symptoms, including chest pain and shortness of breath.

• #5 Polycythemia/Erythrocytosis • MSPCA-Angell

  https://www.mspca.org/angell_services/24386-2/

  When a patient is found to have a significantly elevated red blood cell (RBC) count, we usually report that they have polycythemia. However, there is often confusion between the terms polycythemia and erythrocytosis. Erythrocytosis is defined as an increase in solely RBCs. Once erythrocytosis has been identified, the next question is whether it is a relative erythrocytosis (far more common) or an absolute erythrocytosis. Patients with a relative erythrocytosis should show concurrent signs of dehydration (tachycardia, prolonged CRT, hypotension, concentrated urine, pre-renal azotemia, etc.), typically do not show clinical signs attributed to erythrocytosis, and have a history supporting the development of dehydration. In cases of relative erythrocytosis, the PCV typically does not exceed 65% and will return to normal with appropriate fluid therapy, which is the mainstay of therapy for these cases. It is also important to consider iatrogenic causes for erythrocytosis. Aggressive blood transfusions could result in erythrocytosis. Additionally, patients receiving erythropoietin (EPO) supplementation could develop a high PCV if EPO therapy is excessive. Absolute erythrocytosis occurs when there is a true increase in the number of red blood cells present. Most clinical signs of absolute erythrocytosis are related to an increase in blood viscosity. As viscosity increases, there is a decrease in blood flow in capillaries, resulting in tissue hypoxia, sludging, and thrombosis. It is crucial to distinguish relative erythrocytosis from absolute erythrocytosis, as the treatment varies significantly. In cases of relative erythrocytosis, the treatment is aggressive IV fluid, as discussed above. With absolute erythrocytosis, initial treatment is removal of whole blood. Recommendations are for removal of 10-20 mL/kg of blood at a time consecutively until clinical signs are improved. If the underlying cause for erythrocytosis can be corrected, it should be treated (i.e. removal of an EPO secreting tumor, prevention of carbon monoxide exposure). However, most patients diagnosed with absolute erythrocytosis do not have a curable condition and need to be treated throughout their lifetime. Often, signs can be controlled with intermittent phlebotomy, every 1-2 months based on sequential PCV/TS monitoring. If the PCV and clinical signs cannot be controlled with phlebotomy, myelosuppressive drug therapy with hydroxyurea can be considered. Antithrombotic therapy can also be considered in patients with absolute erythrocytosis. In general, the prognosis for patients with primary erythrocytosis is guarded, whereas the prognosis for patients with secondary erythrocytosis depends on the underlying cause. Patients with suspected erythrocytosis can benefit from referral to Angell.

  https://www.merckvetmanual.com/circulatory-system/erythrocytosis-polycythemia/erythrocytosis-polycythemia-in-animals

  Erythrocytosis is a relative or absolute increase in the number of circulating RBCs, resulting in the PCV, hematocrit, RBC count, and hemoglobin concentration increasing above reference intervals. […] For relative erythrocytosis due to dehydration, treatment consists of rehydration with IV fluids and treating the underlying cause. […] For primary erythrocytosis (polycythemia vera), treatment initially consists of phlebotomy (1020 mL/kg to decrease the PCV to 50%60%) with simultaneous fluid replacement. […] Primary erythrocytosis is usually diagnosed by excluding secondary causes, and it is typically treated by phlebotomy and hydroxyurea.

• #7 Investigation and management of erythrocytosis

  https://pmc.ncbi.nlm.nih.gov/articles/PMC7829024/

  Primary erythrocytosis or autonomous production of excess erythrocytes most commonly occurs due to polycythemia vera (PV), a myeloproliferative neoplastic process that may be asymptomatic or may present with thrombosis, constitutional or vasomotor symptoms, or splenomegaly. […] Secondary erythrocytosis, which is more common than PV, has a broad differential diagnosis that includes hypoxic lung disease, cyanotic congenital heart disease, medications (e.g., testosterone) and erythropoietin-producing malignant disorders. […] To reduce the risk of thrombosis, most patients with PV are treated with low-dose acetylsalicylic acid and phlebotomy to achieve a target hematocrit value of less than 0.45, whereas patients at high risk for thrombosis may receive cytoreductive therapy. […] Treatment of secondary erythrocytosis should be directed at the underlying cause, and phlebotomy is not routinely recommended.

• #9 Secondary Erythrocytosis – Blood Disorders – Merck Manual Consumer Version

  https://www.merckmanuals.com/home/blood-disorders/myeloproliferative-disorders/secondary-erythrocytosis

  Erythrocytosis is increased production of red blood cells (erythrocytes). […] Secondary erythrocytosis develops generally as a result of a disorder that increases erythropoietin secretion. Erythropoietin is a hormone made in the kidneys that stimulates the bone marrow to produce red blood cells. […] Secondary erythrocytosis that is caused by oxygen deprivation may be treated with oxygen. People who smoke are advised to quit and are offered treatments to assist quitting. Any underlying disorder that is causing the oxygen deprivation and secondary erythrocytosis is treated as effectively as possible. […] In some people, phlebotomy (in which some of the person’s blood is removed) is used to lower the number of red blood cells. It is rare that phlebotomy is needed in secondary erythrocytosis.

  When a patient is found to have a significantly elevated red blood cell (RBC) count, we usually report that they have polycythemia. However, there is often confusion between the terms polycythemia and erythrocytosis. Erythrocytosis is defined as an increase in solely RBCs. Once erythrocytosis has been identified, the next question is whether it is a relative erythrocytosis (far more common) or an absolute erythrocytosis. Patients with a relative erythrocytosis should show concurrent signs of dehydration (tachycardia, prolonged CRT, hypotension, concentrated urine, pre-renal azotemia, etc.), typically do not show clinical signs attributed to erythrocytosis, and have a history supporting the development of dehydration. In cases of relative erythrocytosis, the PCV typically does not exceed 65% and will return to normal with appropriate fluid therapy, which is the mainstay of therapy for these cases. It is also important to consider iatrogenic causes for erythrocytosis. Aggressive blood transfusions could result in erythrocytosis. Additionally, patients receiving erythropoietin (EPO) supplementation could develop a high PCV if EPO therapy is excessive. Absolute erythrocytosis occurs when there is a true increase in the number of red blood cells present. Most clinical signs of absolute erythrocytosis are related to an increase in blood viscosity. As viscosity increases, there is a decrease in blood flow in capillaries, resulting in tissue hypoxia, sludging, and thrombosis. It is crucial to distinguish relative erythrocytosis from absolute erythrocytosis, as the treatment varies significantly. In cases of relative erythrocytosis, the treatment is aggressive IV fluid, as discussed above. With absolute erythrocytosis, initial treatment is removal of whole blood. Recommendations are for removal of 10-20 mL/kg of blood at a time consecutively until clinical signs are improved. If the underlying cause for erythrocytosis can be corrected, it should be treated (i.e. removal of an EPO secreting tumor, prevention of carbon monoxide exposure). However, most patients diagnosed with absolute erythrocytosis do not have a curable condition and need to be treated throughout their lifetime. Often, signs can be controlled with intermittent phlebotomy, every 1-2 months based on sequential PCV/TS monitoring. If the PCV and clinical signs cannot be controlled with phlebotomy, myelosuppressive drug therapy with hydroxyurea can be considered. Antithrombotic therapy can also be considered in patients with absolute erythrocytosis. In general, the prognosis for patients with primary erythrocytosis is guarded, whereas the prognosis for patients with secondary erythrocytosis depends on the underlying cause. Patients with suspected erythrocytosis can benefit from referral to Angell.

• #72 What is Erythrocytosis? – HealthTree for Myelofibrosis

  https://healthtree.org/blood-cancer/community/articles/what-is-erythrocytosis

  Erythrocytosis occurs when the red blood cells are extremely elevated, damaging normal blood circulation and the bodys function. […] Since it is a secondary condition with multiple possible causes, the main goal is to treat the underlying cause. However, there is a treatment for those patients whose red blood cell volumes cause circulation issues. […] Large amounts of red blood cells can make the blood thicker and harder to flow through small blood vessels. […] Especially when hematocrit is higher than 60%-65%. These patients may experience symptoms such as impaired alertness, dizziness, headaches, and compromised exercise tolerance and may face increased risk for blood clots, strokes, heart infarction, and deep venous thrombosis. For those cases, treatment with phlebotomy is indicated.

• #73 Post-transplant erythrocytosis after kidney transplantation: A review

  https://www.wjgnet.com/2220-3230/full/v11/i6/220.htm

  Post-transplant erythrocytosis (PTE) is defined as persistently elevated hemoglobin 17 g/dL or hematocrit levels 51% following kidney transplantation, independent of duration. It is a relatively common complication within 8 months to 24 months post-transplantation, occurring in 8%-15% of kidney transplant recipients. […] Most patients with PTE experience mild symptoms like malaise, headache, fatigue, and dizziness. […] In the evaluation of PTE, it is important to exclude other causes of erythrocytosis including malignancy before treatment. Angiotensin converting enzyme inhibitors (ACE-I) and angiotensin receptor blockers (ARBs) are the mainstays of treatment. Increased ACE-I/ARB use has likely contributed to the falling incidence of erythrocytosis. […] Post-transplant erythrocytosis is an important disease process after kidney transplantation that manifests in a typical population based on risk factors, responds well to pharmacotherapy in most cases, and over time, has led to minor sequelae and favorable outcomes with minimal impact on patient and allograft survival.

  During the first 20 months of testosterone therapy, the cumulative incidence of hematocrit 50.4% was 12.6%, hematocrit 52% was 1.0%, and hematocrit 54% was 0.6%. […] Severe erythrocytosis (hematocrit 54%) is a rare outcome of gender-affirming testosterone therapy. Clinical recommendations should reconsider the need for routine frequent erythrocytosis screening within the first year of testosterone therapy for patients who prefer to minimize laboratory draws. […] These results support a growing base of literature that suggests that although testosterone use is associated with erythrocytosis (defined as hematocrit 50.4%), severe erythrocytosis (hematocrit 54%) is uncommon among those who use testosterone as a medical intervention for gender affirmation. […] Our findings show that routine erythrocytosis screening every 3 months in the first year of treatment for all individuals on testosterone may be unnecessary.
