Hey Ewa,
After 25 years on Sulfasalazine/Salazopirine for my UC (in remission) I started developing Eosinophilia. My values were so high my GI actually freaked out. When the eos were at their highest I got episodes of oedema and dermographism. I did a lot of tests to rule out parasites, allergies, and nastier causes... without any success.
My haematologist got in contact with a eosinophilia specialist (a reference in the field). She suggested that in very rare cases, 5-ASA drugs can cause eosinophilia (couldn't even find something on google about this). Together with my GI I tapered off the Sulfasalazine (making me flare) which brought the eosinophils back to normal levels (took a few weeks to see an effect).
It looks like I developed an intolerance to Sulfasalazine after all this time. Mesalazine has to same effect on me. Once I quit those class of drugs, my eosinophilia strongly improved. I do have to mention my values go up and down, but it has never been as high as when I was taking the Sulfasalazine.
(Ironically, I need to take much stronger drugs now to keep my UC barely under control, whereas Sulfasalazine keeps me in remission).
hope this helps,
