Churg?Strauss Syndrome, now known as Eosinophilic Granulomatosis with Polyangiitis, is a rare autoimmune disorder. It is characterized by inflammation of the blood vessels (vasculitis) and tissue damage, particularly affecting the lungs, sinuses, and skin.

The disease commonly begins with or is accompanied by new-onset asthma, which can be severe and difficult to control with standard therapy.
The systemic inflammation causes widespread damage to organ systems. This combination of severe, new-onset asthma and systemic vasculitis is the defining feature of the disorder and demands immediate diagnosis and specialized management.
Symptoms define a multi-system failure. They include severe, worsening asthma, persistent sinus problems, fever, and weight loss. A characteristic symptom is the appearance of purpuric skin lesions (red or purple spots from bleeding under the skin) and severe nerve damage (neuropathy), causing pain, numbness, and weakness. The inflammation can also affect the heart and kidneys. The progressive nerve and muscle damage can be debilitating, limiting mobility.
Diagnosis relies on confirming both systemic vasculitis and high eosinophil counts in the blood and tissue. Blood tests check for elevated eosinophils and specific antibodies (MPO-ANCA). A biopsy of the affected tissue (skin or nerve) is often needed to confirm the presence of vasculitis.
Churg?Strauss Syndrome can impact eye health due to blood vessel inflammation. Vasculitis can affect the retinal or orbital vessels, leading to retinal occlusion (blockage), scleritis (severe, painful inflammation of the white of the eye), or vision loss. Ocular symptoms can be one of the earliest signs of the disorder's severity.
Treatment is aggressive and involves high-dose corticosteroids to suppress the autoimmune inflammation quickly. Immunosuppressive drugs are used to control the disease long-term and prevent damage to organs, including the eyes.
No, it is a chronic disorder, but remission is often achieved with consistent immunosuppressive therapy.
No, this is extremely rare in children. It typically affects people between the ages of 30 and 50.
Asthma or a history of allergies is a very common precursor to the onset of the disorder.
See a specialist if your asthma worsens or you develop numbness in your hands or feet. This syndrome can cause "Scleritis" or "Uveitis" in the eyes. Early systemic treatment is critical to prevent organ damage to the heart and kidneys.
