MRCP revision battle 20.6: Churg Strauss

Churg Strauss is a rare vasculitic disease of unknown aetiology.

The classic triad associated with it is:
  • asthma
  • eosinophilia
  • vasculitis of small and medium vessels
The vasculitis usually affects the lungs, peripheral nerves and skin.

Glomerulonephritis may occur with Churg Strauss but renal failure is rare.

It is pANCA positive.

Treatment is with high-dose steroids.

Now to the final battle of the day, a bit about ANCA...
