[Mixed idiopathic cryoglobulinemia and glomerulonephritis (author's transl)]

Mixed idiopathic cryoglobulinemia may be associated with renal failure. When this occurrence appears some characteristic lesions may be observed on renal biopsies. The authors describe a case of mixed idiopathic cryoglobulinemia with nephrotic syndrome and hypertension. Histologic data and immunofluorescence study of renal biopsies are similar to those described in the published literature. If antigen-antibody complex seems to be for all authors the etiological feature of renal disease, the treatment to apply is not well known. The related case had been treated by plasmapheresis and the authors give their results to short and mean term.
