Q

Absolute indications for dialysis

A

AEIOU

Acidosis

Electrolytes - HYPERkalemia

Intoxications - methanol, eth glycol, lithium, aspirin

Overload - hypervolemia that can’t be solved

Uremia - based on clinical presentation, like pericarditis

Q

Glomerular d/o vs tubular d/o

A

In glomerular but not in tubular:

  • need biopsy usually
  • steroids and immunosuppressive meds for tx

In tubular but not in glomerular:

  • acute presentation,
  • caused by toxins
  • does not cause nephrotic syndrome

Q

Acute Interstitial Nephritis

  • features
  • seen on labs
  • causes
A

Polyruia and sterile pyruria (maybe some WBC casts) are early manifestations

acute interstitial renal inflammation + pyuria + eosinophils (hypersensitivity) + azotemia

happens after drugs 
METHICILLIN #1
NSADs
captopril

Q

Acute tubular necrosis

  • causes
  • stages
A

Toxic (#1 aminoglycosides) or Ischemic (more serious, prerenal azotemia usually (shock, sepsis) or crush injury w/ myoglobinuria) → granular casts (muddy brown)

o This is medullary necrosis and ATN is limited to outer medullar segments b/c renal medulla is susceptible to ischemic injury b/c low medullary blood flow → glomeruli look normal

o Stages: (1) inciting event → (2) Maintenance (oliguric, risk of hyperkalemia & met acidosis) → (3) Recovery (polyuric, risk of hypoK)

Q

Renal papillary necrosis

  • what is it

necrosis of renal papillae (supplied by vasa recta) = hematuria, proteinuria

o “POSTCARDS” = Pyelonephritis, Obstruction, Sickle Cell, TB, Cirrhosis, Analgesic abuse (phenacetin, acetaminophen, aspirin), Renal transplant rejection, Diabetes (#1), Systemic vasculitis

o DACS = Diabetes Mellitus (#1), Acute pyelonephritis, Chronic phenacetin use (acetaminophen), Sickle Cell

  • standard maintenance fluid
  • dextrose to inhibit muscle breakdown

D5W

  • dilute powdered meds
  • only some stays intravascular b/c diffuses into TBW compartment; not great to replenish intravascular

Lactated ringer’s solution

  • good to replacing intravascular volume
  • NOT a maintenance fluid
  • common trauma resuscitation

Q

Tx Hyper K

A

IV calcium

  • decreases membrane excitability
  • be careful giving this to pts on dig b/c can worsen toxicity

Shift K into cell

  • glucose + insulin (fastest)
  • sodium bicarb (for emergencies)

Remove K from body

  • Kayexalate (exchange resin)
  • hemodialysis
  • diuretics

Fever
Renal failure (rather than neuro sx of TTP)

Shiga-toxin binds to the globotriaosylceramide (Gb3) receptor on the surface of the glomerular endothelium
This action includes a cascade of signaling events leading to apoptosis and binding of leukocytes to endothelial cells.
The Shiga-toxin-activated endothelial cells then become thrombogenic (clot-producing)
Additionally, the binding action of Shiga-toxin inactivates a metalloproteinase called ADAMTS13

Q

How do you tell if metabolic acidosis is of renal or extrarenal origin just by labs?

A

Extrarenal causes of metabolic acidosis are associated with an appropriate increase in net acid excretion primarily reflected by high levels of urine ammonium excretion, whereas kidney causes of this condition are associated with low net acid excretion and decreased urine ammonium levels.

Can get Urine ammoium w/ urine anion gap

Metabolic acidosis of extrarenal origin is suggested by a large, negative UAG caused by significantly increased urine ammonium excretion. Conversely, metabolic acidosis of kidney origin is suggested by a positive UAG related to minimal urine ammonium excretion.

A

\fever, tonsillar exudates, tender anterior cervical lymphadenopathy, and absence of cough

often used as a prediction rule in patients with suspected GABHS infection.
