The prognostic significance of glomerular inflammation in patients with lupus membranous glomerulonephritis (MGN) was evaluated by classifying 100 renal biopsies from lupus patients according to World Health Organization (WHO) criteria and correlating the histology with clinical data. There were 22 cases of MGN: in 3 the lesion was pure MGN (Va); in the remainder, diffuse MGN was modified by superimposed mesangial proliferation in 6 (Vb), segmental glomerulonephritis (GN) or sclerosis in 10 (Vc), and diffuse GN in 3 (Vd). Patients in the four categories had similar clinical presentations. When the 4 patients with active proliferative glomerulonephritis (PGN) were grouped and compared to those without PGN, they had more active serologies. Quantitation of glomerular electrondense deposits in MGN showed variation in the percentage of basal lamina covered by subepithelial deposits, segmental subepithelial deposits in 4 cases, focal segmental subendothelial deposits in most cases and massive subendothelial deposits in 5 biopsies. 4 of the latter patients had active PGN, suggesting that only extensive subendothelial deposits are pathogenetically significant. The predicted 5-year survival for all MGN patients was 90%, and the only 2 deaths were not related to renal failure. Thus, it appears valid to include mixed lesions in the membranous category, but it is our impression that the immediate course and prognosis of SLE and associated PGN depends upon the extent and reversibility of the inflammatory lesions.
