Treatment largely depends upon individual disease progression and the nature of presenting symptoms. Antimalarials, corticosteroids, and other drugs may be prescribed, if deemed appropriate by the treating physician. Most patients will maintain a diagnosis of undifferentiated connective tissue disease. However, about one third of UCTD patients will differentiate to a specific autoimmune disease, like rheumatoid arthritis or systemic sclerosis. About 12 percent of patients will go into remission. Severe vitamin D deficiency has been associated with the progression of UCTD into defined connective tissue diseases. The presence of the autoantibodies anti-dsDNA, anti-Sm,
