I do not believe that it does as it is classified as an autoimmune condition.

Hello @roboedit, I see your question may have slipped through the cracks and no one gave you an answer. The good news is that it doesn't normally lead to a decreased lifespan but can impair the quality of your life unless you get treatment and also make some lifestyle changes to help. My first bout of PMR took 3-1/2 years to taper off of prednisone and the second time it popped it's ugly head was 6 years after it went into remission. It took me 1-1/2 years to taper off of prednisone the second time and what helped is I made a few changes in my lifestyle - eating healthier and exercising more.
