Any elevation of hemoglobin or hematocrit above normal values for age and sex is considered erythrocytosis. 1. 2- All of the following are causes of secondary absolute polycythemia, except: A. … Causes of secondary polycythemia or physiological polycythemia may be caused by: High Altitude (altitude sickness). Answer: Polycythemia Vera. When too many red blood cells are produced, the blood becomes thick, hindering its passage through the smaller blood vessels. secondary polycythemia: Definition Secondary polycythemia is an acquired form of a rare disorder characterized by an abnormal increase in the number of mature red cells in the blood. Cigarette smoking should be ruled out because it is the most common cause of secondary polycythemia. Secondary polycythemia, similar to primary polycythemia vera, is a disorder that causes an overproduction of red blood cells. Differentiating between appropriate secondary polycythemia (eg, high-altitude living, pulmonary disease, tobacco use) and inappropriate secondary polycythemia (eg, tumors) Identifying candidates for erythropoietin (EPO) replacement therapy (eg, those with chronic renal failure) The most frequent symptoms of HAPC include headache, dizziness, breathlessness, sleep disorders, and dilation of veins. The number of red blood cells, the level of the protein that carries oxygen in red blood cells (hemoglobin) and the percentage of red blood cells in the total blood volume (the hematocrit) are abnormally high. Secondary polycythemia would more accurately be called secondary erythrocytosis or erythrocythemia, as those terms specifically denote increased red blood cells. Therefore, it is known as physiologic polycythemia. Living in high altitude and some disease conditions cause secondary polycythemia. Secondary polycythemia.

Hypoxic disease.e.g. On descent, with removal of altitude hypoxia, siEp decreased, but despite secondary polycythemia levels remained measurable and in the range found in subjects normally resident at sea level. Secondary polycythemia and factor V Leiden mutations were the most commonly associated conditions. 1. j lab clin med. An aid in distinguishing between primary and secondary polycythemia . 3- The risk acute myeloid leukemia in polycythemia vera is A. Polycythemia vera may be discovered through a blood count done for another reason, even before people have any symptoms. 1965 aug;66:304-14. secondary polycythemia in adolescents at high altitude. Secondary polycythaemia. Hypoxia is the major stimulus for EPO production. Smoking, high altitudes, mountain climbing, etc. Subsequent evaluation should be aimed at determining the cause. Genetic Mutation: Polycythemia Vera Therefore, the main difference between primary and secondary polycythemia is the causes and effects of each type of absolute polycythemia. Secondary polycythemia can be caused by a variety of erythropoietin-producing renal lesions and cancers. Short description: Secondary polycythemia. High-altitude polycythemia (HAPC) is a chronic high-altitude disease that can lead to an increase in the production of red blood cells in the people who live in the plateau, a hypoxia environment, for a long time. Polycythemia is a condition in which the body produces too many red blood cells. Secondary polycythemia is caused by natural or artificial factors. 6. It can occur due to rare underlying conditions or certain situations, such as high altitudes. Secondary polycythemia in which the production of erythropoietin increases appropriately is called physiologic polycythemia. Secondary polycythemia is also called secondary erythrocytosis. The red blood cells in some patients with secondary polycythemia may carry an abnormal form of hemoglobin that does not release oxygen readily (high-affinity hemoglobin). Secondary polycythemia resolves when the underlying cause is treated. 3- the risk acute myeloid leukemia in polycythemia vera, is a monoxide high!
