First described in 1972, [1] often called distinct rheumatologic disease, mixed connective tissue disease (MCTD) is variously considered an overlap (i.e., overlap connective tissue disease) between systemic lupus erythematosus (SLE), scleroderma, and polymyositis; a specific subset of scleroderma with objective features of other diseases, such as SLE or polymyositis; or a distinct disease entity. [2] In Medical Subject Headings, it is termed "A syndrome with overlapping clinical features of systemic lupus erythematosus, scleroderma, polymyositis, and Raynaud's phenomenon. The disease is differentially characterized by high serum titers of antibodies to ribonuclease-sensitive extractable (saline soluble) nuclear antigen and a "speckled" epidermal nuclear staining pattern on direct immunofluorescence." [3]
From an immunologic standpoint,antibodies against U1 small nuclear ribonucleoproteins (anti-U1 snRNP OR anti-U1 RNP) are characteristic.[4]
A report of two cases suggested tumor necrosis factor-alpha inhibitors could aggravate the disease. Antibodies to dual-stranded DNA, diagnostic for lupus, disappeared after the drug was stopped. [5]
