A Retrospective Analysis of Outcomes in Patients with Hepatorenal Syndrome At Methodist Dallas Medical Center

Description

Hepatorenal syndrome (HRS) is a common cause of acute kidney injury (AKI) in patients with liver disease \[1\]. Increased activity and presence of vasodilators such as nitric oxide in cirrhotic patients leads to vasodilation, especially in the splanchnic circulation, resulting in hemodynamic changes that precipitate renal injury \[1\]. Patients may present with elevated serum creatinine (Cr), benign urine sediment, and low urine sodium \[1\].

Eligibility Criteria

  • * All patients \>18 years old that were hospitalized between April 1st 2019 and April 1st 2023 who either presented with HRS-AKI or developed a diagnosis of HRS during the hospital course. HRS-AKI will be defined based on the ICA criteria, described below:
  • 1. Presence of cirrhosis, acute liver failure, or acute-on-chronic liver failure
  • 2. An increase in serum Cr of ≥0.3 mg/dL within 48 hours or ≥50% from baseline value and/or urinary output ≤0.5 mL/kg of body weight for ≥6 hours (requires use of a urinary catheter)
  • 3. No full or partial response for ≥2 days of diuretic withdrawal and volume expansion with albumin (dosed at 1 g/kg of body weight/day)
  • 4. Absence of shock
  • 5. No current or recent treatment with nephrotoxic drugs
  • 6. Absence of parenchymal renal disease
  • 7. Suggestion of renal vasoconstriction based on FENa \<0.2%
  • * 1. HRS-AKI patients \<18 years of age 2. All patients hospitalized between April 1st 2019 and April 1st 2023 without a diagnosis of HRS-AKI.
