Patnaik MM, Tefferi A. Secondary causes of increased red blood cell mass (e.g., heavy smoking, chronic pulmonary disease, renal disease) are more common than polycythemia vera and must be excluded. The word polycythemia indicates increased red blood cells, white blood cells, and platelets. Nested high-resolution melting curve analysis a highly sensitive, reliable, and simple method for detection of JAK2 exon 12 mutations--clinical relevance in the monitoring of polycythemia. Affected people may also have excess white blood cells and platelets.Conditions where the body makes too many of these cells are known as myeloproliferative neoplasms. With secondary thrombocytosis, the platelet count is usually < 1,000,000/mcL (< 1,000,000 × 10 9 /L), and the cause may be obvious from the history and physical examination (perhaps with confirmatory testing). Because this disease can be difficult to manage, patients should be referred to a specialized center in order to be managed by an interprofessional team. History. 90(5):2057-61.

You may need one or more treatments to manage the disease. J Pediatr Hematol Oncol. Smoking, for example, interferes with this process, so it is a common cause of secondary polycythemia. The job of a red blood cell is to deliver oxygen to the body tissues. Secondary polycythemia is defined as an absolute increase in red blood cell mass that is caused by enhanced stimulation of red blood cell production. The expanded red blood cell mass may partially or totally compensate for the lack of oxygen delivery and result in tissue oxygenation to its normal level.

Erythrocytosis and the Chuvash von Hippel-Lindau mutation. The body attempts to compensate for the deficiency by manufacturing more hemoglobin and erythrocytes. The development of secondary erythrocytosis in response to tissue hypoxia is physiologic and probably beneficial to many patients. When a patient gets polycythemia as a sequel to an underlying disease condition, it is known as secondary polycythemia. Treatment aims to reduce your risk of blood clots and relieve symptoms. Treatment with ruxolitinib was found to reduce the volume of spleen in a third of MPN‐SVT patients after 2 years (Pieri et al, 2017).
