What are the best treatments for Churg Strauss Syndrome?

TL;DR: Treatment for Churg-Strauss Syndrome, now clinically known as Eosinophilic Granulomatosis with Polyangiitis (EGPA), typically involves high-dose corticosteroids combined with immunosuppressive or biologic therapies to induce and maintain remission. Because this systemic vasculitis affects multiple organs, management must be highly personalized by a multidisciplinary team based on the severity of organ involvement and the patient's individual clinical response.

What are the primary medications for Churg-Strauss Syndrome?

The standard of care for Churg-Strauss Syndrome is designed to reduce inflammation and suppress the overactive immune system. Initial treatment usually involves high-dose systemic corticosteroids (e.g., prednisone or prednisolone). For patients with severe organ-threatening disease, physicians often add conventional immunosuppressants such as cyclophosphamide, methotrexate, or azathioprine. In recent years, biologic agents have become a cornerstone of therapy, most notably mepolizumab (Nucala), which is FDA-approved specifically for the treatment of Churg-Strauss Syndrome.

What does a multidisciplinary care team look like?

Managing Churg-Strauss Syndrome effectively requires a coordinated team approach. Because the disease can impact the lungs, heart, nerves, and skin, the following specialists are often involved in a patient's care:

• Rheumatologist: Often leads the management of the systemic vasculitis.


• Pulmonologist: Essential for monitoring asthma-like symptoms and lung function.


• Immunologist/Allergist: Helps manage the underlying eosinophilic response.


• Neurologist: Monitors for mononeuritis multiplex or peripheral neuropathy.


• Cardiologist: Required to assess cardiac involvement, a significant concern in Churg-Strauss Syndrome.

How is treatment effectiveness monitored?

Treatment success in Churg-Strauss Syndrome is measured by the reduction of eosinophil counts in the blood, the stabilization or improvement of organ function, and the ability to taper off corticosteroids. Effectiveness varies significantly; while some patients achieve long-term remission, others experience chronic relapses, necessitating ongoing adjustments to their therapy. At DiseaseMaps.org, 126 people with Churg-Strauss Syndrome have shared their experiences, highlighting the diverse ways patients respond to different treatment protocols.

Are there non-pharmacological or emerging therapies?

Beyond medication, physical and occupational therapy are vital for patients experiencing nerve damage or muscle weakness. Ongoing clinical trials continue to investigate new biologic therapies and targeted inhibitors to improve outcomes for those with refractory Churg-Strauss Syndrome. Patients are encouraged to discuss these trials with their specialists to determine if they are candidates for emerging research.

Next steps

• Consult with a rheumatologist or vasculitis specialist to create a personalized treatment plan.


• Track your symptoms and medication side effects in a journal to share during clinical visits.


• Join the DiseaseMaps community to connect with other patients and share experiences regarding treatment management.


• Monitor the NIH ClinicalTrials.gov database for new trials specifically recruiting for EGPA.
