Mixed connective tissue disease. Appearance of antibodies to ribonucleoprotein following corticosteroid treatment. 1979

D Alarcon-Segovia

Antibodies to ribonucleoprotein are the serological marker of mixed connective tissue disease (MCTD). Five patients are presented who had negative or low titer anti-RNP antibodies despite characteristic MCTD. In all 5 patients antibodies to RNP appeared after they had taken prednisone for periods ranging from 3 wk to 15 months.

UI	MeSH Term	Description	Entries
D008875	Middle Aged	An adult aged 45 - 64 years.	Middle Age
D008947	Mixed Connective Tissue Disease	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.
