The diagnosis of light chain deposition nephropathy is based on the immunohistochemical demonstration of monoclonal light chain deposits within connective tissue matrix and on the presence at the ultrastructural level of electron-dense granular deposits along glomerular and tubular basement membranes. A nodular glomerulopathy characterized by amorphous periodic acid-Schiff-positive and argyrophilic widened mesangium and nodules is described in three patients with light chain deposition nephropathy. Light microscopic examination did not allow discrimination between the glomerular changes found in these specimens and the nodular glomerulosclerosis described in four patients with well-documented diabetes mellitus. Electron microscopic examination revealed microtubular fibrils 10 to 12 nm thick in mesangial areas in both groups. Such microfibrils could be glycoproteins. Immunofluorescence localization of matrix proteins, by staining with affinity-purified antibodies to types I, III, IV, and V (A, B) collagens, fibronectin, laminin, and heparan sulfate-containing proteoglycans, showed similar distributions in the two conditions. The mechanism of this abnormal accumulation of mesangial and glomerular basement membrane matrix proteins in two different conditions remains unknown. [less ▲]
