I have mild to severe cGvHD in my arms, hands, legs, feet, stomach and GI track.

I’ve been having ECP treatments, Monday & Tuesday, every other week since 13 September, 2010

Benefits: eosinophil count has been coming down into the normal range, slowly a reduction in GVHD symptoms

Side effects: tired, scaring where the needle is inserted into the vein

Hope this helps and good luck with the treatments.
