BCG instillations and autoimmune disease

Is there anyone out there that has had the initial 6 sessions of BCG instillations whilst at the same time having an autoimmune disease. In my case I was diagnosed with Sjogren's Syndrome some 15 years ago which is being treated with eye-drops and at "flare-up" times with steroids. I have noticed that since my initial instillations, my Sjogren's has become considerably worse. I cannot find any published literature on the subject regarding the worsening of any autoimmune disorders and I wonder whether any member has had a similar experience.
