Management of Peripheral Edema in Patients with Chronic Liver Disease and Ascites
Pathophysiology and Clinical Implications
- The development of peripheral edema in cirrhotic patients with ascites is associated with secondary aldosteronism, which plays a major role in renal sodium retention in cirrhosis, according to the American Association for the Study of Liver Diseases 1
- Patients with peripheral edema can undergo more aggressive diuresis without complications, and can lose up to a certain amount of weight per day without significant plasma volume reduction or renal dysfunction, as recommended by the Clinical and Molecular Hepatology society 2
Treatment and Monitoring
- The American Association for the Study of Liver Diseases recommends moderate sodium restriction (2g or 90 mmol/day) as first-line treatment for patients with ascites and peripheral edema 3
- Spironolactone (starting at 50-100 mg/day, up to 400 mg/day) and furosemide (starting at 20-40 mg/day, up to 160 mg/day) are recommended as first-line treatments for patients with ascites and peripheral edema, according to the Clinical and Molecular Hepatology society 2
- Regular assessment of body weight, vital signs, serum creatinine, sodium, and potassium is recommended during treatment, as advised by the Clinical and Molecular Hepatology society 2
- Diuretics should be reduced or stopped if severe hyponatremia, acute kidney injury, or hepatic encephalopathy develops, according to the Clinical and Molecular Hepatology society 2
Large-Volume Paracentesis and Albumin Therapy
- Large-volume paracentesis is recommended as first-line treatment for tense ascites (grade 3), with albumin supplementation (6-8 g per liter of ascites removed), as recommended by the Clinical and Molecular Hepatology society 2
- Albumin therapy may improve diuretic response and reduce hospitalization days, according to the Clinical and Molecular Hepatology society 2
