How do I know if I have Churg Strauss Syndrome?

Churg-Strauss Syndrome, now medically known as Eosinophilic Granulomatosis with Polyangiitis (EGPA), is a rare systemic vasculitis characterized by a history of asthma, high levels of eosinophils in the blood, and inflammation of small blood vessels. If you experience the sudden onset of severe, treatment-resistant asthma alongside unexplained nerve pain or skin rashes, you should consult a specialist for a thorough evaluation.

What are the warning signs of Churg-Strauss Syndrome?

The clinical presentation of Churg-Strauss Syndrome typically unfolds in three phases. The first phase often involves allergic rhinitis and late-onset asthma. The second phase is marked by eosinophilia (elevated white blood cells), while the third phase involves vasculitis, or inflammation of the blood vessels, which can damage organs. Recognizing the progression of Churg-Strauss Syndrome is key, as symptoms often mirror common respiratory issues until systemic involvement occurs.

How can I recognize symptoms of Churg-Strauss Syndrome?

While many people have asthma, Churg-Strauss Syndrome presents with distinct patterns that deviate from typical allergic asthma. Look for these specific indicators:

• Asthma that becomes suddenly severe and difficult to manage with standard inhalers.


• Persistent sinus issues, such as nasal polyps or recurrent sinusitis.


• Unexplained numbness, tingling, or "pins and needles" sensations in the hands or feet (mononeuritis multiplex).


• Skin lesions, such as nodules or purpura (small purple spots).


• Unexplained fatigue, weight loss, or night sweats.

How is Churg-Strauss Syndrome diagnosed?

There is no single test for Churg-Strauss Syndrome. Diagnosis requires a combination of clinical assessment and lab results. If you suspect you have Churg-Strauss Syndrome, ask your doctor about:

1. A Complete Blood Count (CBC) to check for elevated eosinophil levels.


2. ANCA (Anti-neutrophil cytoplasmic antibody) testing, though only about 40% of patients with Churg-Strauss Syndrome test positive.


3. Imaging studies, such as chest X-rays or CT scans, to assess lung involvement.


4. Biopsy of affected tissue (skin, nerve, or lung) to confirm vasculitis.

When should I seek urgent medical care?

Seek immediate emergency care if you experience sudden loss of sensation, profound muscle weakness, coughing up blood, or severe abdominal pain, as these may indicate acute organ involvement related to Churg-Strauss Syndrome.
