  • Title: Changing histopathology patterns in lupus nephropathy.
    Author: Mahajan SK, Ordónez NG, Spargo BH, Katz AI.
    Journal: Clin Nephrol; 1978 Jul; 10(1):1-8. PubMed ID: 699393.
    Abstract:
    The initial clinical and histologic renal findings and the subsequent course of 90 patients with SLE were evaluated in a study of the natural history of lupus nephropathy. Initial renal biopsy revealed focal glomerulonephritis in 32 patients, diffuse glomerulonephritis in 47, membranous nephropathy in seven and minimal changes in four. Forty-one patients were rebiopsied three months to five years later; ten of 15 patients with focal glomerulonephritis showed progression to diffuse glomerulonephritis or membranous nephropathy, whereas changes in morphologic pattern were less common in the other types of lupus nephropathy. There was no difference between the patients with the focal lesion who progressed and those who did not in age, sex distribution, duration of SLE prior to biopsy, renal function, and serological studies; however, the patients with progression initially had more proteinuria, higher histologic activity on light microscopy, and more intensive glomerular electron-dense deposition. Focal lupus glomerulonephritis progresses frequently to diffuse glomerular involvement. Certain clinical and morphologic findings at initial evaluation may help to predict future progression in the course of lupus nephropathy.
