Renal dysfunction in patients with cirrhosis: Where do we stand?

Area of Science:

• Nephrology
• Hepatology
• Internal Medicine

Background:

• Cirrhosis patients with renal failure are high-risk, complicating diagnosis and treatment.
• Accurate assessment of renal function, differentiating acute kidney injury (AKI), chronic kidney disease (CKD), or AKI on CKD is crucial.

Purpose of the Study:

• To clarify the latest therapeutic modalities for renal dysfunction in cirrhosis.
• To provide recommendations and algorithms for clinical practice in managing these complex patients.

Main Methods:

• Exclusion of prerenal causes of AKI.
• Renal ultrasound and urine microscopy for AKI differentiation.
• Assessment of acute renal function using modified AKIN staging.
• Consideration of renal biopsy for parenchymal renal disease.
• Management strategies including hemodynamic monitoring, fluid balance, infection control, and pharmacotherapy.

Main Results:

• Distinguishing HRS from acute tubular necrosis based on clinical presentation and diagnostic tests.
• Terlipressin is the primary treatment for established HRS, with midodrine and norepinephrine as alternatives.
• Dialysis and transjugular intrahepatic portosystemic shunt serve as bridging therapies for transplantation candidates.

Conclusions:

• A systematic approach to diagnosing and managing renal dysfunction in cirrhosis is essential.
• Current therapeutic options, including pharmacotherapy and supportive measures, can improve outcomes.
• Adherence to proposed algorithms can optimize clinical management and patient status, especially for transplantation.
