title: An evaluation of diabetic and pseudodiabetic glomerulosclerosis.
abstract: Diabetic glomerulosclerosis must be either a primary manifestation or a secondary consequence of the metabolic abnormalities of diabetes. Several earlier reports have attempted to support the former hypothesis by describing cases of pathognomonic renal lesions in nondiabetic subjects; however, the clinical and pathologic data in these reports are inconclusive. We have reviewed our experience at the University of Virginia Hospital with 447 percutaneous renal biopsies performed over a period of four years from July 1973 through July 1977. Of these cases, only two appeared to represent diabetic glomerulosclerosis occurring in nondiabetic subjects. Upon further investigation, one case provided to be light chain disease demonstrated by immunofluorescence staining. The other case, on repeat renal biopsy, proved to be membranoproliferative glomerulonephritis. We conclude that a diagnosis of diabetic glomerulosclerosis must be viewed with suspicion in nondiabetic subjects. Suspected cases should be labeled pseudodiabetic glomerulosclerosis and investigated further.
