A 53-year-old woman with adult polycystic kidney disease (PKD) developed a nephrotic syndrome. Evaluation of the renal biopsy specimens showed typical findings of membranous nephropathy (MN). There are few reports of nephrotic syndrome associated with PKD and only one proved to be MN. The possible mechanism of the association of PKD with MN was evaluated. Autoantibodies against the brush border were not detected in this patient's serum by indirect immunofluorescence. Three monoclonal antibodies against the tubular brush border and epithelial cell of distal tubulus did not react with subepithelial deposits in the biopsy specimen. Therefore tubular brush border antigen which was reported to induce membranous nephropathy was not detected in the immune complexes deposited in the glomeruli. So we could not determine any direct relationship between PKD and MN. The reaction of antibodies against basement membrane components (type IV collagen, laminin, fibronectin, heparansulfate proteoglycan) with the basement membranes of the cysts was evaluated by indirect immunofluorescence. The reaction with anti-heparansulfate proteoglycan antibody was decreased compared with normal tubular basement membrane. The reactivity to anti-fibronectin antibody was remarkably increased in the cystic walls, tubules, and interstitium. Changes of tubular basement membrane antigens was observed in PKD.

D009404	Nephrotic Syndrome	A condition characterized by severe PROTEINURIA, greater than 3.5 g/day in an average adult. The substantial loss of protein in the urine results in complications such as HYPOPROTEINEMIA; generalized EDEMA; HYPERTENSION; and HYPERLIPIDEMIAS. Diseases associated with nephrotic syndrome generally cause chronic kidney dysfunction.

D005455	Fluorescent Antibody Technique	Test for tissue antigen using either a direct method, by conjugation of antibody with fluorescent dye (FLUORESCENT ANTIBODY TECHNIQUE, DIRECT) or an indirect method, by formation of antigen-antibody complex which is then labeled with fluorescein-conjugated anti-immunoglobulin antibody (FLUORESCENT ANTIBODY TECHNIQUE, INDIRECT). The tissue is then examined by fluorescence microscopy.

D001485	Basement Membrane	A darkly stained mat-like EXTRACELLULAR MATRIX (ECM) that separates cell layers, such as EPITHELIUM from ENDOTHELIUM or a layer of CONNECTIVE TISSUE. The ECM layer that supports an overlying EPITHELIUM or ENDOTHELIUM is called basal lamina. Basement membrane (BM) can be formed by the fusion of either two adjacent basal laminae or a basal lamina with an adjacent reticular lamina of connective tissue. BM, composed mainly of TYPE IV COLLAGEN; glycoprotein LAMININ; and PROTEOGLYCAN, provides barriers as well as channels between interacting cell layers.
