I am a little confused. If you have mctd then by definition you have lupus, scleroderma and polymyositis. You might or might not exhibit symptoms of all of them and those symptoms can come and go. U1 RNP antibodies are required for a diagnosis of mctd and anti U1-70 KD autoantibodies are often present.
Treatment is pretty much the same. Steroids are normally the protocol or possibly an immuno suppressant like methotrexate or imuran or a combination of them. Some of us also get ivig for resistant cases.
My initial diagnosis was lupus and 2 months later mctd. How special, I had both and scleroderma was thrown in as a bonus!
Mixed connective tissue disease (systemic lupus, scleroderma, polymyositis), Raynauds phenomena, Hypertension, Barrett's esophagus.
Meds: prednisone (6mg & tapering), 75mg imuran, lisinopril 40mg, maxide 37.5/25mg, norvasc 5 mg, folic acid, potassium, aciphex 20mg, multi vitamins.
Maintain your optimism and you can beat the odds.
