Polycythemia vera is acquired, whereas primary familial and congenital polycythemia is dominantly inherited. In contrast, secondary erythrocytosis or polycythemia is caused by circulating erythropoiesis-stimulating factors, typically erythropoietin. Secondary erythrocytosis can result from smoking, heart or lung disease, high altitudes, or ...

Nov 2, 2023 · Secondary polycythemia is driven by erythropoietin (EPO), which can be released due to hypoxemia, as seen in people living at high altitudes, those with chronic lung diseases, obstructive sleep apnea (OSA) and smoking. It can also be directly released by an underlying EPO secreting tumor, such as renal cell carcinoma.
Nov 15, 2022 · BACKGROUND: Polycythemia Vera (PV) is a myeloproliferative neoplasm characterized by uncontrolled proliferation of erythrocytes with frequent co-stimulation of myeloid and megakaryocyte progenitor cells. Prior to the utilization of molecular testing, subnormal or low erythropoietin (EPO) levels were an important component in the diagnosis of PV.
Feb 8, 2019 · The most common causes of secondary polycythemia are: sleep apnea. smoking or lung disease. obesity. hypoventilation. Pickwickian syndrome. chronic obstructive pulmonary disease (COPD) diuretics ...

More oxygen can be carried to tissues when erythropoietin stimulates red blood cell production in the bone marrow to compensate for hypoxia. Neonatal (newborn) polycythemia can be seen in 1%-5% of newborns. The most common causes may be related to the transfusion of blood, transfer of placental blood to the infant after delivery, or chronic ...
Jul 5, 2022 · Erythrocytosis is having a high concentration of red blood cells. Your levels may be high for many reasons. Some causes, like dehydration, are less concerning than others, like polycythemia vera, a serious blood disorder. Getting diagnosed and receiving treatment can prevent complications associated with erythrocytosis, like life-threatening ...

Aug 10, 2020 · Absolute erythrocytosis can be driven by a clonal bone marrow disease (PV) or be secondary to another disease, including a physiologic response to increased erythropoietin secondary to hypoxia, drugs11 or erythropoietin-producing solid tumours12, 13 . Congenital causes of erythrocytosis include high-oxygenaffinity hemoglobins, erythropoietin receptor mutations and alterations in oxygen-sensing ...
