How to manage a patient on dialysis with cirrhosis and normal liver function tests?

From the Guidelines

Managing a patient on dialysis with cirrhosis and normal liver function tests requires a multifaceted approach that prioritizes hemodynamic stability, prevention of liver disease progression, and careful medication management, as outlined in recent guidelines 1. The primary goal is to maintain hemodynamic stability while preventing progression of liver disease. Medications should be adjusted for renal clearance, with careful attention to those metabolized by the liver.

• For pain management, acetaminophen can be used at reduced doses (maximum 2g/day), while avoiding NSAIDs due to bleeding risk.
• Opioids should be used cautiously with reduced doses and extended intervals.
• Beta-blockers like carvedilol (starting at 3.125mg daily) or propranolol (starting at 10mg twice daily) may be used for portal hypertension management, with dose titration based on heart rate and blood pressure.
• Diuretics should be used judiciously, with spironolactone starting at 25mg daily and furosemide at 20mg daily, adjusting based on volume status, as recommended by the EASL clinical practice guidelines 1. Regular monitoring should include comprehensive metabolic panels, complete blood counts, coagulation studies, and albumin levels every 1-2 weeks initially, then monthly once stable.
• Patients should be assessed for hepatic encephalopathy, which may be treated with lactulose (15-30ml orally 2-3 times daily) and rifaximin (550mg twice daily), following the French recommendations for diagnosis and management of hepatic encephalopathy 1. The most critical aspect of management is to balance the treatment of both conditions while minimizing medication-related complications and optimizing patient outcomes, taking into consideration the latest evidence on preventing AKI in patients with cirrhosis 1.

From the Research

Management of Patients on Dialysis with Cirrhosis and Normal Liver Function Tests

• The management of patients on dialysis with cirrhosis and normal liver function tests requires careful consideration of the underlying liver disease and its potential impact on renal function 2.
• Despite having normal liver function tests, patients with cirrhosis may still experience renal dysfunction due to severe splanchnic arterial vasodilation and systemic inflammation 2.
• The assessment of renal function is crucial in guiding the management of patients with cirrhosis, and serum creatinine is still the most commonly used biomarker for estimating glomerular filtration rate (GFR) and assessing acute kidney injury (AKI) 2.
• New biomarkers of GFR, such as cystatin C, may improve the assessment of GFR and prognostic stratification in patients with cirrhosis 2.

Dialysis in Patients with Cirrhosis and Normal Liver Function Tests

• Peritoneal dialysis may be a suitable option for patients with cirrhosis and ascites who require dialysis, as it can provide excellent hemodynamic tolerance and effective solute and water removal 3.
• However, patients with cirrhosis and normal liver function tests may still be at risk of complications related to dialysis, such as hypotension, gastrointestinal bleeding, and intraperitoneal sepsis 4.
• The choice of dialysis modality should be individualized based on the patient's specific needs and medical condition, and careful monitoring of renal function and liver disease is essential to guide management decisions 4, 3.

Prescribing Medications in Patients with Cirrhosis and Normal Liver Function Tests

• When prescribing medications to patients with cirrhosis and normal liver function tests, it is essential to consider the potential risks of hepatotoxicity and the need for dose modification in patients with advanced liver disease 5.
• Idiosyncratic drug reactions can occur in patients with normal or abnormal liver function, and drugs with predominant hepatic metabolism and/or excretion should be used with caution in patients with cirrhosis 5.
• Prescribing practices may need to be altered in patients with decompensated cirrhosis, and careful consideration of the potential risks and benefits of medication use is essential to optimize patient outcomes 5.
