Q

Minimal Change Dz

assoc? tx?

A

Nephroic syn, effacemnt of podocytes via cytokines. associaed w/hodgkin lymphoma, tx w/steroids

17
Q

Focal Segmental glomerulosclerosis

assoc? sx?

A

nephrotic syn, collagen depo, HTN, dec GFR, pink sclerosis

-assoc: HIV, Heroin, SS, Idiopathic

18
Q

Membranous Nephropathy

causes? assoc?

A

nephrotic syn, sub-epi IC depo causing “string of pearls”.

  • cause: DISC = drugs, infection, SLE, cancer/hepC
  • assoc: assoc w/ renal vein thrombosis which is often seen with RCC
19
Q

membranoproliferative glomerulonephritis

A

nephrotic syn, BM thickens due to IC depo causing MESANGIAL CELL PROLIF = HYPERCELLULARITY

  • T1: tram track: assoc w/ a1at def, HBV/C
  • T2: ribbin w/C3 nephritic factor
20
Q

NephrItic Syn sx? dz’s?

A

RBC casts, <3.5g/d, HTN

=> PSGN, Rapidly Progressive GN, Alport, IgA Nephrop, Henoch Schonlein Purpura

21
Q

Post-Streptococcal Glomerulonephritis(PSGN)

A

Nephritic Syndrome, IC depo = decrease C3&C4 in serum, look for child whose post-strep

22
Q

Rapidly Progressive GN

3 types? dz’s?

A

Nephritic Syndrome w/cresents of Fibrin + macrophages.

  1. Linear IF = GOODPASTURES = Ab to A3 of T4collagen = lungs and kidney
  2. Granular: PSGN, SLE GN
  3. Paui-Immune: Wegners, MPAN, Churg Strauss
23
Q

Alport Syndrome

A

Nephritic Syndrome, XL def in T4 collagen, ocular, hearing loss, basket weave BM

24
Q

IgA Nephropathy(Berger dz)

A

Nephritic Syndrome, IgA depo, episodic, usually follows URTI

25
Q

henoch Schonlein Purpura

A

Nephritic Syndrome, systemic IgA depo, w/rash, purpura, etc

26
Q

When would you see OXALATE CRYSTALS? how do you treat this?

A

seen in suicidal ppl who ingest antifreeze(ethylene glycol)

tx: FOMEPIZOLE + dialysis + NaHCO2(correct acidosis)

27
Q

Hepatorenal syndrome

dx? tx?

A

RF due to Liver failure = vasoconstriction of affarent arteriol causing decrease in perfusion.

dx: 1.5L colloid = no change
tx: octreotide, Midodrine, tx cause

28
Q

RTA T1

ph? assoc?

A

pH>5.5 , Stones, impaired H+ excretion in distal tubules, bicarb <10

29
Q

RTA T2

ph? assoc?

A

Impaired HCO3 resorb in prox tubule, pH<5.5, Bone probs/pains, bicarb 12-20

30
Q

RTA T4

ph? assoc?

A

decrease aldo or aldo resistance, pH <5.5, no bones, no stones, elevated K, >17 bicarb

31
Q

Acute Tubular Necrosis(ATN)

tx? sx?

A

tubular dmg due to decrease perfusion causing inflammation = PGI2 causes ischemia = cell apop = no NaK pump!

sx: muddy casts, increased K, decreased Na, eleved U-Na, Low osm
tx: hydration + support

32
Q

Acute/Allergic Interstitial Nephritis(AIN)

sx? tx?

A

allergy/irritation to somthing = wks of drug exposure, or infection

sx: 80% ppl have rash + fever, eosinophilia, WBC casts, Proteinuria, elevated IgE
tx: hydration + stop drug
