The nephrotic syndrome is defined by a urinary protein levelexceeding 3.5 g per 1.73 m2 of body-surface area per day. Atthe turn of the century, clinicians distinguished a nephriticsyndrome of inflammatory origin and a nephrotic syndrome ofpresumed degenerative origin. Today these concepts are outmoded,but the term "nephrotic syndrome" is clinically useful and haspersisted, because heavy proteinuria, irrespective of its origin,is associated with a spectrum of clinically important sequelae,particularly sodium retention, hyperlipoproteinemia, and thromboembolicand infectious complications. The definition given above isarbitrary, however, and special significance should not be givento the . . . [Full Text of this Article]
