Eosinophilic Lung Disease - It’s a Thing

Eosinophilic Lung Disease - It’s a Thing

From Episode 175 on the Medicine stream. With Prof Lynelle Johnson.

Confession: I’d heard of the term eosinophilic lung disease, but I thought it was some rare condition that dogs get in other countries where they struggle with lots of lungworm, and maybe fungal diseases. Apparently I was wrong, as we learnt from Prof Johnson in this episode. Here are some key things to know, for anyone else with the same gaps in their knowledge:

  • Prof Johnson says that of the cases they work up for chronic coughing, about 15% have eosinophilic lung disease. 

  • It can be nasty, with serious cases looking over much like pneumonia. 

  • Lung rads can look very much like cancer. 

  • You can reliably diagnose it with a transtracheal wash - no need for BAL. 

  • And despite how severe they can be - you can usually totally fix them with pred. Like - cure it. (Lots of pred, for quite a long time, but still.)
