Thanks for the information. I was on azithioprine for a year and 10 months and stopped taking it in Feb 2020. Went back for my 6 month Oncologist appointment in August, no cancer. Still not on any immune suprressing medications for antisynthetase syndrome and after the initail, horrible flare up that nearly killed me, once the HPV cancer was diagnosed and treated, I have had no more symptoms. I am back to hiking about 5 miles per day and working out on my weights. Back to my pre-illness weight. Have a few long term side effects from such a high dose of prednisone for so long and from the 35 rediation treatments on my neck, but other than that, doing well. Drs say I am a case that is in remission with no medications. I feel thankful and blessed.
