43. Membranous Nephropathy Membranous nephropathy is the most frequent cause of the nephrotic syndrome in adults (about 30% of cases). May be idiopathic. May be associated with epithelial neoplasms, infections (esp hepatitis B), SLE, and the use of certain drugs such as gold and penicilamine.

44. Membranous Nephropathy Membranous Nephropathy is caused by the accumulation of immune complexes within the kidney itself. Immune complexes are deposited in a thickened basement membrane creating a "spike and dome" appearance on electron microscopy.

45. MEMBRANOUS GLOMERULONEPHRITIS

47. Acute Nephritic Syndrome The most common cause of the acute nephritic syndrome is poststreptococcal (post- infectious) glomerulonephritis. This is an immune-complex mediated disease, with IgG and C3 seen along the GBMs by IF ("lumpy-bumpy" pattern) and large subepithelial "humps" by EM.
