Treatment of Hepatorenal Syndrome

The first-line treatment for hepatorenal syndrome is terlipressin plus albumin, which has a response rate of 40-50% in patients with HRS Type 1. 1

Diagnostic Criteria

Before initiating treatment, confirm the diagnosis of hepatorenal syndrome:

  • Increased serum creatinine (>133 μmol/L or 1.5 mg/dL)
  • Exclusion of other causes of renal failure
  • Perform diagnostic paracentesis with SAAG calculation
  • Abdominal and renal ultrasound to confirm cirrhosis, assess portal hypertension, and rule out obstructive uropathy 1

Treatment Algorithm

First-Line Treatment: Terlipressin plus Albumin

  • Dosing regimen:
    • Terlipressin: Start at 1 mg IV every 4-6 hours
    • Increase to maximum 2 mg every 4-6 hours if serum creatinine does not decrease by at least 25% after 3 days
    • Albumin: 1 g/kg on day 1, followed by 20-40 g/day 1
  • Important limitation: Patients with serum creatinine >5 mg/dL are unlikely to experience benefit 2
  • Predictors of favorable response:
    • Serum bilirubin <10 mg/dL before treatment
    • Increase in mean arterial pressure >5 mm Hg at day 3 of treatment
    • Lower baseline serum creatinine (<5.0 mg/dL) 1

Alternative Treatments

  1. Norepinephrine plus albumin (in ICU setting) 1
  2. Midodrine + octreotide + albumin 1
    • Midodrine: Titrate up to 12.5 mg orally three times daily
    • Octreotide: 200 μg subcutaneously three times daily
    • Albumin: 10-20 g/day IV for up to 20 days
    • Note: This regimen can be administered outside the ICU and even at home 1

Monitoring and Complications

  • Monitor serum creatinine, mean arterial pressure, and cardiovascular status
  • Cardiovascular complications occur in approximately 12% of patients treated with terlipressin 1
  • Recurrence after withdrawal of terlipressin therapy is uncommon, and retreatment is generally effective 1

Prevention Strategies

  • Norfloxacin (400 mg/day) reduces the incidence of HRS in advanced cirrhosis 1
  • Pentoxifylline (400 mg three times daily) may prevent HRS development in severe alcoholic hepatitis 1
  • Treatment of spontaneous bacterial peritonitis with albumin plus antibiotics reduces the risk of HRS development 1

Definitive Treatment

  • Liver transplantation is the only curative treatment for HRS 1
  • Expedited referral for transplantation should be considered for all patients with cirrhosis, ascites, and HRS
  • Simultaneous liver-kidney transplantation should be considered for patients with significant kidney damage 1

Bridge Therapies

  • Continuous renal replacement therapy (RRT) may be used as a bridge to liver transplantation in non-responders to vasoconstrictors 1
  • Transjugular Intrahepatic Portosystemic Shunt (TIPS) may be considered in selected patients with partial response to medical therapy, but is contraindicated in severe liver failure or significant encephalopathy 1

Prognosis

Despite treatment, the prognosis for HRS patients remains poor, with a median survival of approximately 3 months for all HRS patients. Untreated Type 1 HRS has a median survival of approximately 1 month, emphasizing the importance of early diagnosis and treatment 1.
