Overview
Mainly classified into primary and secondary causes based on the presence or absence of genetic mutations and underlying disorders.
Classification
Once the diagnosis of absolute erythrocytosis has been established, red cell mass (RCM > 125% of predicted), classification can be done accordingly:[1][2][3][4]
- Primary erythrocytosis[5][6]
- Secondary erythrocytosis
- Erythropoietin receptor-mediated - High oxygen affinity hemoglobin - Bisphosphoglycerate mutase deficiency - VHL (Von Hippel-Lindau) gene mutation (Chuvash erythrocytosis) - PHD2 (prolyl hydroxylase domain) mutations - HIF-2 alpha mutations
- 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 [7][8][9]
