title: Sickle cell crisis and endothelin antagonists.
abstract: Sickle cell crisis may be more complex than a vaso-occlusive event in response to hypoxia. Endothelin-1 (ET-1) is a potent vasoconstrictor and mitogen secreted in response to hypoxia. ET-1 contributes to the vaso-occlusion and inflammation in sickle cell crisis. ET-1 antagonists may be useful in the prevention and treatment of crisis.
