I was hoping someone else would start this thread, but here goes. AILD aka Autoimmune liver & bile ducts disease, often associated with other AI conditions like Hashimoto's. If you've got this then you're quite a rare bird and probably know nobody with it, except possibly online. I know there are a few others on MN with AILD as we had a chat about it a few years ago when I was using a different name.
I have AIC (c being for cholangiopathy). It's an overlap syndrome with features of AIH and PBC and with negative ANA. My condition is stable just now. I am on an immunosuppressant called MMF (Mycophenolate Mofetil). MMF is okay. I think I'm just happy it suits me because azathioprine made me very ill.
Other conditions I have include underactive thyroid (Hashimoto's), dry eyes, joint pains, chronic fatigue, at times dreadful brain fog. Also asthma and perennial rhinitis (hay fever but all the year round, not just summer). I also have deafness caused by antibody production, I.e. Autoimmune Ear Disease.
