[Sharp's syndrome: a new entity amongst the connective tissue diseases?].
Sharp and coworkers have coined the name "Mixed connective tissue disease" to an association of symptoms seen in different connective tissue diseases. Those symptoms are associated with a special antibody directed against ribonucleoproteins (RNA-P). The presence of this antibody accounts for a high titer of antinuclear fluorescent antibody, of the speckled type. The most frequents symptoms in the association described by Sharp are Raynaud's phenomenon, swollen fingers, non deforming arthritis. We have observed those symptoms without any further symptoms of connective tissue disease, but with the presence of anti-RNA-P antibody. We suggest to coin the name of Sharp's syndrome to that clinical association. The significance of anti-RNA-P, and their correlation with a remarkable benignity of the disease, is discussed.
