Day #107 - Hepatorenal Syndrome

Today we talked about acute decompensated cirrhosis with massive ascites and hepatorenal syndrome.

Hepatorenal syndrome (20% or acute renal failure in cirrhotics) (good articles here and here):
  • Two types:
    • Type 1: Acute rise in creatinine (usually within 2 weeks)
    • Type 2: More gradual rise and usually not progressive
  • Criteria for diagnosis (revised 2007):
    • Cirrhosis with ascites
    • Creatinine >120
    • No current or recent nephrotoxins
    • No shock
    • Doesn't improve with volume rescucitation (with albumin) and stopping diuretics x 2 days
    • Less then 500mg proteinuria/24h and no large hematuria or sonographic evidence of renal parenchymal disease or obstruction
  • Treatment of type 1 HRS
    • Generally as a bridge to transplantation! Not usually on their own if transplant will never be an option
    • Norepinephrine infusion, or midodrine 7.5-12.5mg PO TID with octreotide 100-200mcg SC TID, or terlipressin infusion
      • With albumin 1g/kg on day 1 and 20-40g q24h
    • Treat 5-15 days with goal Cr <120
    • Haemodialysis should generally *not* be used as it does not improve the poor outcomes -- though can be used as a bridge to transplant
    • TIPS - in patients with CPS less than twelve and bilirubin <85 and without severe encephalopathy can have survival benefit.
  • Outcomes
Alcoholic hepatitis:

  • People talk about treating with corticosteroids in severe disease; however, a recent meta-analysis questions the evidence -- though perhaps the problem is we use the wrong scale to identify patients who will benefit.
  • There is also evidence for pentoxyfiline, though deciding who should get this over steroids, or if they would be better in combination is still pending.
I have previously talked about cirrhosis and advanced cirrhosis.
