drugs (NSAIDS)
allergies
Hodgkins
hematologic malignancies
Infection

Question 10

Answer 11

light microscopy shows no changes but EM shows flat podocytes and loss of GBM

Question 12

focal segmental glomerulosclerosis pathophys

Answer 12

an unknown circulating factor leads to sclerosis of the glomeruli of some nephrons damaging the podocytes

Answer 14

heroin
HIV
obesity
HTN

Question 15

FSGS treatment

steroids (do not reverse scarring)
immunosuppression in resistant disease
ACEi/ARB, statins

Question 16

primary membranous nephropathy pathophys

Answer 16

anti-PLA2R antibodies form immune complexes that lead to Podocyte injury

Question 17

minimal change disease pathophys

Answer 17

cytokine mediated damage of podocytes

Question 23

primary amyloidosis treatment

Answer 23

treat underlying systemic disease

Question 24

diabetic nephropathy pathophys

Answer 24

chronic hyperglycemia leads to GBM thickening and eventually sclerosis, decreasing GFR

all pts with nephrotic syndrome are at increased risk of ____ because of ____

Answer 28

thromboembolism | protein loss/hypoalbuminemia

Question 29

why does nephrotic syndrome cause edema?

Answer 29

loss of proteins in blood (peeing them out) leads to increased interstitial fluid

Answer 32

membranous nephroapthy

Question 33

why is DVT a possible complication of nephrotic syndrome?

Answer 33

there is a loss or protein C, S and antithrombin III and overproduction of clotting proteins
