  • 3rd side (hint)
Dx:
Edema, lipiduria, foamy urine, hypoalbuminemia, hyperlipidemia, hypercoagulation, protein in urine
Nephrotic syndrome
Dx:
"Maltese crosses" in urine
cholesterol in urine

(Nephrotic syndrome)
Why does the nephrotic syndrome pt have edema?

hypercoaguability?
Edema - decrease ion serum proteins and oncotic pressure

Hypercoag - loss of Proteins C and S and antithrombin III
Dx:
child w/ epithelial foot process loss on EM

Tx?
Minimal Change Dz

Tx: steroids
Dx:
glomerular scarring involving limited number of glomeruli w/ IgG and complement deposition

Most common in what patients?
(5)
Focal Segmental Glomerulosclerosis

Common in (Halt MID Stream):
HIV;
Men (younger) w/ HTN
IV drug users;
DM;
Sickle cell
Halt MID Stream
What can Focal Glomerulosclerosis lead to?
(2)

Tx?
HTN and Chronic Renal Dz

Tx: Cyclophosphamide
First line of Tx for all Nephrotic syndrome

Tumor
Rule of thirds for Membranous GN
1/3 get CRF

1/3 have spontaneous remission

1/3 remain nephrotic w/o pregression
Tx for Membranous GN
(2)
Cyclophosphamide

Chlorambucil
Dx:

Deposition of what causes glomerular damage in poststrep GN?

Tx?
Deposition of IgG, C3 and C4 in a grandular pattern

Tx underlying infection
Dx:
hematuria immediately after an infection or exercise
IgA nephropathy

(Berger's Dz)
what (and where) is the immune complex deposition of IgA nephropathy?
Mesangeal deposition of IgA and C3
Dx:
immune deposits on BM cause it to look double-layered

what is it associated w/?
(2)
Membranoproliferative

("Tram-track" appearance)

Assoc w/:
Hepatitis C
Cryoglobinemia
How is type I membranoproliferative different then type II?
Type I:
slowly progressive

Type II:
low serum C3 due to Auto-Ab vs C3
Tx of Membranoproliferative for adults (2) and kids
Adults:
ASA
Dipyridimole

Kids:
Steroids
Dx:
Fulminant renal failure w/ proteinuria, hematuria and RBC casts and epithelial cell proliferation in glomeruli
