Learn About Hypereosinophilic Syndrome

What is the definition of Hypereosinophilic Syndrome?
Hypereosinophilic syndrome (HES) refers to a rare group of conditions that are associated with persistent eosinophilia with evidence of organ involvement. Signs and symptoms vary significantly based on which parts of the body are affected. Although any organ system can be involved in HES, the heart, central nervous system, skin, and respiratory tract are the most commonly affected. The condition was originally thought to be "idiopathic" or of unknown cause. However, recent advances in diagnostic testing have allowed a cause to be identified in approximately a quarter of cases.

A Longitudinal Study of Familial Hypereosinophilia (FE): Natural History and Markers of Disease Progression

Summary: Eosinophils are a type of white blood cell. Elevated eosinophil levels can damage the heart, nerves, and other organs, in the syndrome known as hypereosinophilic syndrome (HES). Some individuals have a hereditary form of HES known as familial eosinophilia (FE). More research on the causation and mechanisms of HES is needed in order to design more effective and less toxic therapies. This study will...
