Overview
Divided into primary and secondary causes based on underlying genetic mutations and other factors(refer to classification).
Causes
Common Causes
Common causes of polycythemia may include:
- Primary erythrocytosis
- Secondary erythrocytosis
- Congenital:
- Erythropoietin receptor-mediated
- High oxygen affinity hemoglobin
- Bisphosphoglycerate mutase deficiency
- VHL (Von Hippel-Lindau) gene mutation (Chuvash erythrocytosis)
- PHD2 mutations
- HIF-2 alpha mutations
- Acquired:
- Hypoxia driven
- Central hypoxic process:
- Chronic Lung disease
- Right-to-left cardiopulmonary vascular shunts
- Carbon monoxide poisoning
- Smoker's erythrocytosis
- Hypoventilation syndromes including sleep apnea (high-altitude habitat)
- Local renal hypoxia:
- Renal Artery Stenosis
- End-Stage Renal Disease
- Hydronephrosis
- Renal cysts (polycystic kidney disease)
- Postrenal transplant erythrocytosis
- Pathologic EPO production:
- Tumors
- Cerebellar hemangioblastoma
- Meningioma
- Parathyroid carcinoma/adenomas
- Hepatocellular carcinoma
- Renal cell cancer
- Pheochromocytoma
- Uterine leiomyomas
- Exogenous EPO:
- Drug associated
- EPO administration
- Androgen administration
- Idiopathic erythrocytosis [1] [2]
