MO267HIGHER FRACTIONAL EXCRETION OF TOTAL PROTEIN IS A PREDICTOR OF PROGRESSION IN IDIOPATHIC MEMBRANOUS NEPHROPATHY

Background and Aims Lower estimated glomerular filtration rate (eGFR) and higher proteinuria are the most sensitive predictor of the development of progressive renal insufficiency in various glomerular diseases. On the other hand, the onset of idiopathic membranous nephropathy (iMN) shows insidious progression, and the prognosis varies significantly. Therefore, it is difficult to predict the renal outcome in MN, using only the severity of...
