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.
Cellcept kills B cells. Rituxan is also a B cell killer at a much higher dose.
I have a fatty liver and DM with overlapping Scleroderma. I also have Chronic Kidney Disease. I would not qualify for a Rituxan infusion. You can read Rituxan side effects on Drugs.com too.
Rituxan is a medication when you have been on other DMARDs for a reasonable to "long" period of time and the disease is at a point where the other meds no longer work. Rituxan is also a beneficial med for some cancers too.
I also have active disease. I take 5mg of Prednisone and 750mg of Cellcept. My active disease is well managed at this point. There will probably come a time when my medication dosages will need to go higher too.
Do visit The Myositis Association website at www.myositis.org for additional opinions and research literature on infusions too.
Consider your situation carefully. It never hurts to get a second opinion about your bloodwork, and current medication dosages. I would definitely consider a second opinion or talking to other doctors to see if an infusion would be a consideration. If you are really ready for infusion, then other medical professionals would be in agreement too.
I know that there are many people who will be able to share their infusion experiences. Best wishes on your decisions too.
My understanding is from a cancer perspective. It is a bio-therapy like chemotherapy. I was told it doesn't kill cells but it attaches to B cells and forces your body to attack those cells. While I was on Rituxan, I had fatigue and headaches.
I would work with your doctor on which is right for you. It really depends on your symptoms and your general health.
