Polymyositis & Dermatomyositis Support Group
Polymyositis (PM) is a type of chronic inflammation of the muscles (inflammatory myopathy) related to dermatomyositis and inclusion body myositis. The inflammation is predominantly of the endomysium in polymyositis, whereas dermatomyositis is characterized by primarily perimysial inflammation.
I can definitely relate to the "guinea pig" feeling, and it seemed worse for me while I was going through the trial and error approach with the standard meds. By the time I got into the Rituxan trial, though, I had been sick for 2+ years and felt really comfortable because the docs running the trial had so much more experinece with DM and PM than my local rheumy.
Based on my life-changing experience, I would highly encourage anyone to participate in a clinical trial if you have the opportunity. You'll need to occasionally check the clinicaltrials.gov links that are posted above, because you can't count on your primary rheumy to keep up with this information. He or she should, however, be able to help you get enrolled in a trial if you meet the necessary requirements.
