Nephrology Flashcards
AKI etiology after arterial cath
- CIN
2. atheroembolic emboli (if persistent 5 days after) + Eos
Renal injury after bowel prep
phosphate nephropathy - check phosphate level
avoid fleet enema
> 50 yo
CKD
DM
Abdominal compartment syndrome
IAP >20 w/ AKI (N 6-7)
Treatment of Abdominal compartment syndrome
decompressive laparotomy
Minimal change dz clues
- sudden onset
- Hodgkins dz + NSAIDS
FSGS
AA patient with nephrotic syndrome
HIV
obesity
membranous nephropathy
malignancy associated (25% is from a secondary cause)
Ddx for nephrotic syndrome a/w AKI
- MCG w ATN or
AIN - membranous w. b/l renal vein thrombosis
- amyloid w cast nephropathy
definitive dx of nephrotic syndrome
renal bx
Role of prophylactic AC in nephrotic syndrome
none
Role of bicarb in CKD when bicarb is <22
slows progression of CKD (sodium bicarbonate or sodium citrate)
Consequences of untreated chronic metabolic acidosis
muscle loss
bone loss
Treatment for primary Minimal change
glucocorticoids
ace/arb
diuretics
cholesterol lowering meds if total >200
Monoclonal gammopathy of renal significance
MGUS + renal insufficiency –> renal bx
Treatment of IgA nephropath
ACE/ARB
Role of any immunosuppression in IgA
controversial - never will be the answer
Causes of calcium oxalate stones in malabsorption/diarrhea
- urne citrate is an inhibitor of crystallization that is reduced in metabolic acidosis
- enteric calcium binds to poorly absorbed fat allowing oxalate to be absorbed and excreted in the urine
clues to dysproteinema related kidney disease
older, hypercalcemia, anemia, evidence of proximal tubular dysfunction (hypoK, hypophos, metabolic acidosis,
diagnosis of diabetic nephropathy
clinical. doesn’t need bx if 8 years of dm + nephrotic
Constellation of symptoms a/w MM
Old, hypercalcemia, anemia, NAGMA, AKI
Treatment of ethylene glycol
fomepizole, fluids, HD
lab findings of ethylene glycol
NAGMA, osmlol gap
osmol gap
measured - calculated >10
MOA of renal damage of ethylene glycol
calcium oxalate crystal deposition
AutoAB in 75% of primary cases of membranous glomerulopatny
PLA2R
Treatment of nephrogenic DI
thiazides
Tolvaptaan
vasopressin antagonist use for SIAD
heparin does what to K
hyperK+ (2/2 hypoaldosteronism)
> 50% of RPGN etiology
ANCA associated vasculitis
