In patients with chronic hypoxemic lung disease, polycythemia has been shown to impair the vasodilator response to acetylcholine. |
Dr Alessandro Vannucchi will present the promising results of a Phase III trial for polycythemia vera patients. |
Other symptoms of polycythemia vera include headaches, transient neurologic or ocular complaints, and paresthesias. |
Paraneoplastic erythrocytosis is distinguished from polycythemia vera by the absence of pancytosis and splenomegaly. |
Absolute polycythemia, when the cause is known, is called erythrocytosis. |
Lastly, polycythemia can develop in the presence of certain types of tumours and as the result of the action of adrenocortical secretions. |
