At the other extreme, children may become critically ill with oligoanuric rapidly progressive GN in need of urgent dialysis. A few glomerular diseases are inherited (see Chapter 473), but most forms of GN are acquired and are generally considered to be immunologically mediated. There are three classical clinical syndromes that develop from glomerular injury: acute and chronic glomerulonephritis, defined by the triad of hematuria, hypertension, and azotemia; nephrotic syndrome, defined by proteinuria and hypoalbuminemia; and hemolytic uremic syndrome, defined by microangiopathic hemolytic anemia, thrombocytopenia, and renal insufficiency.
