nephrology, sezer Flashcards
what is the most common cause of hospital acquired AKI?
**Contrast-induced acute kidney injury (CI-AKI)
sepsis
surgery
Nephrotoxic medication
what is Contrast-induced acute kidney injury (CI-AKI) and what does it result in?
iodinated contrast material are drugs containing iodine (that are given to patients to enhance the ability to see blood vessels and organs on medical images)
They are a main cause of hospital acquired acute kidney injury (AKI)
what is the most common cause of Pre-renal AKI?
**hypovolemia (vomiting, diarrhea, blood loss)
**Acute Gastroenteritis
dec cardiac output
dec. effective circulating volume
–>congestive heart failure
–>liver failure
Impaired renal autoregulation: NSAIDs, ACE-1, cyclosporin
what are the main causes of Intrinsic/Tubular ATN (renal) AKI?
-Renal ischemia, nephrotoxic drugs, Endogenous toxins.
-Acute glomerulonephritis, Lupus nephritis, IgA glomerulonephritis, infective endocarditis, Goodpasture disease, Wegener disease
-Infection, medication
-Bilateral renal artery stenosis/thrombosis of vein
, atherosclerotic, vasculitis.
what are the most common Pre-renal AKI causes?
Hypovolemia; volume depletion
volume sequestration
low cardiac output
what is the KDIGO criteria?
-increase in serum creatinine > or equal to 0.3mg/dl within 48 hrs.
or
-increase SCr > or equal to 1.5mg/dl within 7 days.
or
-urine volume <0.5 ml/kg/h for 6hrs /ANURIA (no urine)
what is the RIFLE criteria?
Used to classify Rapid Renal Injury=Acute Renal Injury and which stage is the person in.
1)R; Risk
2)I; Injury
3)F; Failure
4)L; Loss
5)E; End stage renal disease
Acute gastroenteritis may cause which type of AKI?
Pre-renal AKI
Infective endocarditis, atherosclerotic, vasculitis, Wegener disease and Goodpasture disease all cause which type of AKI?
Intrinsic/renal AKI
**what is the definition of chronic kidney disease?
it’s defined as abnormalities in the kidney functions and structure for more than 3 months
***what is the criteria that determines that there’s chronic kidney disease?
***Decrease GFR: less than 60
&
one or more markers of kidney damage; such as Albuminuria >30
who is at risk for chronic kidney disease?
diabetes
family history
hypertension
autoimmune disease
old age
what is one imp cause of acute interstitial nephritis?
drugs; penicillin, NSAIDs, PPI(protein pump inhibitor)
Hypotension(low cardiac output) causes which type of acute kidney injury?
prerenal kidney injury
drugs such as NSAIDs, ACE-1, cyclosporin causes which type of acute kidney injury?
prerenal kidney injury
