5. Smoking.

6. Certain autoimmune diseases, such as rheumatoid arthritis and systemic lupus erythematosus.

7. Certain blood disorders, such as myeloproliferative disorders.

The primary treatment for primary hypereosinophilic syndrome is corticosteroids, such as prednisone. Other treatments may include hydroxyurea, interferon-alpha, and imatinib. In some cases, a bone marrow transplant may be recommended.

The exact cause of primary hypereosinophilic syndrome is unknown. However, it is believed to be an autoimmune disorder, meaning that the body's immune system mistakenly attacks healthy cells. Other possible causes include genetic mutations, infections, and exposure to certain medications or environmental toxins.

The most common symptoms of primary hypereosinophilic syndrome include:

Primary hypereosinophilic syndrome (HES) is a rare disorder characterized by an abnormally high number of eosinophils (a type of white blood cell) in the blood. It is an idiopathic disorder, meaning that the cause is unknown. Symptoms of HES can include fever, fatigue, skin rashes, organ damage, and an enlarged spleen. Treatment typically involves medications to reduce the number of eosinophils in the blood, as well as other medications to treat the symptoms.
