6. Nephrotic Syndrome Clinical syndrome:
1. Massive proteinuria ( > 3.5 gr/day in adult)
2. Hypoalbuminemia (plasma albumin < 3 gm/dL)
3. Generalized edema
Hyperlipidemia and lipiduria
Usually no azotemia, hematuria or hypertension at onset
Can see fatty casts and oval fat bodies in urine microscopically

7. Causes of Nephrotic syndrome (Robbins 9th ed, Table 20-7, page 915)

8. Nephritic Syndrome Clinical syndrome with acute onset:
hematuria (typically with dysmorphic RBCs and RBC casts)
oliguria and azotemia
mild to moderate hypertension
May see proteinuria and edema, but not usually severe
Unifying histologic picture of cellular proliferation in glomeruli, usually with leukocytic infiltration (hypercellularity)
Inflammation injures capillary walls, leading to loss of RBCs into urine & RBC cast formation
Hemodynamic changes lead to reduced GFR  oliguria, azotemia, and some fluid retention
Hypertension probably due to fluid retention and likely renin release due to decreased perfusion to glomeruli (ischemia)
Can be due to primary glomerular disease or secondary to a systemic disorder
Examples: Post-streptococcal (post-infectious) GN & Crescentic GN; see also Lupus GN (later)
