[Successive connective tissue diseases (scleroderma, then lupus). Clinical and biological study of 4 cases].
The authors present 4 patients who had suffered for several years from isolated systemic scleroderma and in whom, after 3, 10, 19 and 22 years, clinical, biological and histological signs of DLE appeared. There was no current further progression of the scleroderma in two cases, at the time of onset of DLE. In the oter two cases, it had disappeared. All four patients had a serum cryoglobulin. In all cases the kidneys were involved histologically : extra membranous glomerulitis in one, segmental glomerulitis in a second, and diffuse progressive glomerulitis in the last two. The authors analyse the biological changes which accompanied the clinical transformation. One of the patients had anti-ribonucleoprotein antibodies. She died from severe renal involvement which would be against the good prognosis usually associated with the presence of this type of antibody.
