Churg-Strauss Syndrome Follow-up

Further Inpatient Care
- Churg-Strauss syndrome (CSS) cases must be followed up very closely at a rheumatology clinic or another specialty clinic. Patients with this syndrome usually need long-term immunosuppressive medications.
- The patient's clinical status, ESR, and eosinophilia should be monitored. The ANCA level does not correlate well with disease activity.[32]
Inpatient & Outpatient Medications
- Inpatient medications include the following:
- Prednisone: Start at 0.5-1 mg/kg/d PO.
- Methylprednisolone is administered in intravenous form at higher doses in the presence of major organ involvement, including cardiac, pulmonary (hemorrhage), renal, or neuropathy.
- Cyclophosphamide is administered in patients with severe or life-threatening complications.[33, 34] The single intravenous dose is 500 mg/m2 of body-surface area. The dose should be reduced in patients with renal failure.
- Other medications include azathioprine, mycophenolate mofetil, and intravenous immune globulin administered in similar fashion as it is used in microscopic polyangiitis or Wegener granulomatosis.[35]
- Plasmapheresis is probably not helpful.[36]
- Interferon alpha might be helpful in treatment.[37, 38]
Complications
- Complications of vasculitis depend on the specific organ system involvement.
Prognosis
- Overall, without treatment, the 5-year survival rate in Churg-Strauss syndrome is about 25%.
- With treatment, the 1-year survival rate is 90% and the 5-year survival rate is 62%.
- Causes of death associated with Churg-Strauss syndrome include the following:
- Cardiac failure, myocardial infarction, or both (most common cause)
- Renal failure
- Cerebral hemorrhage
- Gastrointestinal bleeding
- Status asthmaticus
