@tsc Teri, I had mild anemia too when I was diagnosed with PMR and GCA. My iron levels have recovered with treatment with prednisone and Actemra.

I have read, and you can confirm it through google, that the level of anemia you have when you are diagnosed with GCA can predict your risk of bad events from the GCA (stroke, vision loss, etc) and also your likelihood of a relapse after completing treatment.
