What is mixed connective tissue disease and what can I do about it?

People who have mixed connective tissue disease (MCTD) have complications that overlap due to a combination of one or more rheumatic diseases, including scleroderma, systemic lupus erythematosus, polymyositis (inflammation of the muscles) and rheumatoid arthritis. Often these patients may have a mixture of autoantibodies that are specific for one or more of these diseases. If you or someone you know suspects or have been diagnosed with MCTD, see a rheumatologist for correct evaluation and treatment.
