Discussion Renal prognosis after liver transplantation for hepatorenal syndrome Indication of simultaneous liver-kidney transplantation
Abbreviation • LTX: Liver transplantation • LTA: Liver transplant alone • OLT: Orthotopic liver transplantation • KTA: Kidney transplant alone • LKTX: Liver-kidney transplants • CLKT: Combined liver and kidney transplantation • SLK: Simultaneous liver and kidney • KALT: Kidney transplantation after liver transplantation • HRS: Hepatorenal syndrome
Discussion Renal prognosis after liver transplantation for hepatorenal syndrome Indication of simultaneous liver-kidney transplantation
Approximately 20% of patients undergoing liver transplantation (LTx) demonstrate acute or chronic renal insufficiency
Model for end-stage liver disease (MELD) • Adopted by UNOS(United Network for Oragn Sharing) in 2002 as the basis for deceased donor liver allocation for adult patients Transplantation, 2011
Model for end-stage liver disease (MELD) www.unos.org
LKTx in UNOS Data Transplantation, 2011
MELD Score • Predict mortality and choose candidates most in need of LTx • 3.8[Ln serum bilirubin (mg/dL)] + 11.2[Ln INR] + 9.6[Ln serum creatinine (mg/dL)] + 6.4
Pre-MELD vs Post-MELD Era Patient Survival Graft Survival Post-MELD era ~ Mean MELD: 20.5 Pre-MELD era ~ Mean MELD: 17.0 Aliment Pharmacol Ther 2005; 21: 169
Renal failure before LTx has been reported to predict an increased risk of postoperative renal failure, infection, and death
Renal Function in Liver Disease • Serum creatinine: unreliable(overestimate) • lower muscle mass • decreased hepatic synthesis of creatine, the precursor of creatinine • increased tubular secretion of creatinine • Women will have a lower MELD score than men because of a smaller muscle mass Transplantation, 2011
Acute Kidney Injury • Cause • Hepatorenal syndrome(HRS): 17% • Acute tubular necrosis • Hypovolemia-associated hemorrhage • Infection • ……
Hepatorenal Syndrome • The development of acute renal failure in a patient who usually has advanced liver disease due to cirrhosis, severe alcoholic hepatitis or metastatic tumor
Diagnostic Criteria -1 • Major criteria • Chronic or acute liver disease with advanced hepatic failure and portal HTN • Low GFR ( crea> 1.5mg/dL or 24hr Ccr< 40 mL/min ) • Absence of shock, current or recent treatment with nephrotoxic drugs, fluid losses, or ongoing bacterial infection • No improvement after diuretics withdraw & hydration with 1.5 L of isotonic saline • Proteinuria < 500mg/day and no ultrasonographic evidence of obstructive uropathy or parenchymal renal disease Gut 2007;56: 1310-1318
Diagnostic Criteria -2 • Minor criteria • Urine volume < 500mL/day • Urine Na < 10 mEq/L • Urine osmo greater than plasma osmo • Urine RBC < 50/HPF • Serum Na< 130 mEq/L Gut 2007;56: 1310-1318
Current Diagnostic Criteria • Chronic or acute liver disease with advanced hepatic failure and portal HTN • Low GFR ( crea> 1.5mg/dL) • Absence of shock, current or recent treatment with nephrotoxic drugs, fluid losses • No improvement after diuretics withdraw & hydration with Albumin 1g/kg/BW (up to a maximum 100g) • Proteinuria < 500mg/day and no ultrasonographic evidence of obstructive uropathy or parenchymal renal disease Gut 2007;56: 1310-1318
Classification • HRS Type 1 • HRS Type 2
Pathogenesis of HRS 2 Seminars in Liver Disease 2008;28: 81-95
HRS Type 2 • Less severe (creatinine1.5 mg/dL [132μM/L]) • More slowly progressive with a mean survival of 6 months. • Usually appears spontaneously • Associated with refractory ascites Seminars in Liver Disease 2008;28: 81-95
Pathogenesis of HRS 1 Seminars in Liver Disease 2008;28: 81-95
HRS Type 1 • Rapid impairment of renal function • Serum creatinine level greater than 2.5 mg/dL (>220 μM/L) within 2 weeks • Frequently with precipitating factor • Infection, esp SBP • GI hemorrhage • Acute hepatitis Seminars in Liver Disease 2008;28: 81-95
Survival Gastroenterology 1993;271: 1121- 1125
Treatment -1 • Pharmacological Treatment • Renal vasodilator • Dopamine, PGE1,E2,I2: all been tried without success • Systemic (splanchnic) vasoconstrictor • Terlipressin • Midodrine • Norepinephrine • Volume expander • albumin
