14 - CKD Flashcards
4 parts of the final common pathway of CKD
glomerular sclerosis
tubular atrophy
interstitial fibrosis
vasculosclerosis
gross pathologic changes in CKD
contracted kidneys
thin renal cortex
multiple cysts (acquired cystic dz)
4 main interventions to slow progression of CKD
control glomerular pressure
low protein diet
BP control
ATII axis control
benefit of low protein diet in CKD
lowers glomerular pressure
3 main causes of ESRD
DM
HTN
glomerulonephritis
results of renal failure (lab findings)
high BUN and Cr fluid retention hyponatremia hyper/hypo kalemia acidosis hyperphosphatemia low Vit D > hypocalcemia anemia hypoglycemia etc
ESRD symptoms
tired, apathy, itching, copper penny taste
N/V anorexia, wt loss
pericarditis, uremic myocarditis
peripheral nerve inc conudction time, axonal loss, demyelination
paresthesia, restless leg syndrome, cramps
confusion, eventually coma/seizures
ESRD management
Na restriction / diuretics
cinacalcet, phosphate binders, limit PO4 intake (complicated to balance Ca vs PO4 vs bone dz)
EPO (goal Hgb 10-12)
dialysis (avoid as long as possible)
indications for dialysis
GFR ~10
can wait if stable or gaining weight (not from edema), good protein intake, no signs of uremia
earlier initiation may be better for diabetics (GFR ~15)
