Background

  • Acute renal failure in patient with normal kidneys in presence of acute/chronic hepatic failure
  • Often heralded by the presence of SBP
  • Arterial vasodilatation in the splanchnic circulation, which is triggered by portal hypertension
  • Diagnosis of exclusion


Clinical Features

  • Type 1
    • Doubling of serum creatinine over a 2-week period
    • Progressive oliguria
  • Type 2
    • Gradual impairment in renal function (that may not advance beyond moderate)


Differential Diagnosis


Evaluation[1]

  • Abdominal US
  • Diagnostic paracentesis
  • Ascites fluid cultures and analysis
  • Labs:
    • CBC with diff
    • BMP
    • LFTs
    • Blood cultures
    • Urinalysis
    • Urine electrolytes and osmolality
    • Consultants: alpha-fetoprotein, cryoglobulins
  • All major criteria must be met for diagnosis for both HRS types 1 and 2:
    • Serum creatinine >1.5mg/dL
    • No improvement in renal function after halting diuretics AND admin of 1.5 L of plasma expander
    • Proteinuria <500mg/d
    • No ultrasound evidence of obstructive uropathy or renal parenchymal disease
    • Absence of shock, bacterial infection, hypovolemia, nephrotoxic meds
  • Supporting criteria not required for diagnosis:
    • Uop <500 cc/day
    • Urine sodium <10 mEq/L
    • Urine osmolality > plasma osmolality
    • Urine RBC <50 cells/hpf
    • Serum sodium <130 mEq/L


Management

  • Vasopressors
    • Terlipressin: 0.5-1mg q 4-6 IV us 5-15d
    • Norepinephrine: 0.5-3mg/hr to increase MAP by 10mmHg
    • Midodrine: 7.5mg PO tid with Octreotide 100mcg sq
  • Albumin: 1-1.5g/kg with one of above
  • Other:


Disposition

  • 1-month survival: 50%
  • 6-month survival: 20%
  • Should be evaluated at liver transplant center
  • May require TIPS, vasoconstrictors as bridge to transplant
