    Abstract:
    A case of systemic lupus erythematosus (SLE) associated with minimal change nephrotic syndrome (MCNS) in a 25-year-old female is described. The patient suddenly manifested butterfly rash and proteinuria was first pointed out on March, 1994. On admission, her skin biopsy indicated SLE. Subsequently, she developed nephrotic syndrome. Urinalysis showed heavy proteinuria (4.1 g/day), with no other abnormalities in the urinary sediment. Immunological examination revealed positive antinuclear antibody at a titer of 1:80 with a speckled pattern. Anti-ssDNA and anti-SS-A antibodies were positive, but other antibodies were negative. Serum complement (CH50) was within the normal range (30.5 U/ml). The renal biopsy showed no apparent cellular proliferation or increase of extracellular matrices in glomeruli by light microscopy. Slight deposition of IgG, IgM, C3 and C1q was focally seen in the mesangium and capillary wall by immunofluorescence. Electron microscopic examination revealed small and scattered dense deposits in the mesangium, subepithelium and subendothelium, associated with diffuse fusion of the foot processes of epithelial cells along the glomerular basement membrane. According to the WHO classification, the histological features were compatible with those of lupus nephritis (LN), class Ib. The patient was treated with PREDNISOLONE, Mizorbine and Dilazep, resulting in the disappearance of proteinuria and a normal serum level of total protein. The association of LN and MCNS is very rare. We also investigated the relationship between the intensity of proteinuria and histological types of 53 cases with LN examined in our laboratory. The cases with heavy proteinuria were mostly classified as WHO-Class IV and Class V. We report here a case of LN associated with MCNS and also review the literatures.
