Is treatment with intravenous (IV) or oral (PO) albumin well supported?

From the Guidelines

The use of intravenous (IV) albumin is well-supported in specific conditions such as large-volume paracentesis for cirrhotic ascites, spontaneous bacterial peritonitis, and hepatorenal syndrome, where it helps maintain intravascular volume and renal function, as evidenced by a recent study published in 2024 1.

Key Points to Consider

• IV albumin has established benefits in specific conditions, with typical dosing ranging from 1-1.5 g/kg body weight.
• For most other conditions, including general hypoalbuminemia, malnutrition, or as a volume expander in critically ill patients, albumin therapy shows little advantage over crystalloids and is not recommended as first-line therapy.
• Oral albumin supplementation has essentially no clinical utility as proteins are broken down during digestion and do not directly increase serum albumin levels.
• The body's albumin levels are primarily regulated by hepatic production rather than dietary intake.
• When treating hypoalbuminemia, addressing the underlying cause (such as malnutrition, liver disease, or protein-losing conditions) is more effective than albumin administration.
• Albumin is also relatively expensive compared to alternative treatments, which further limits its routine use when not clearly indicated.

Specific Conditions Where IV Albumin is Beneficial

• Large-volume paracentesis for cirrhotic ascites: IV albumin should be administered at the time of large-volume (>5 L) paracentesis to prevent AKI and hemodynamic instability, as recommended by a recent expert review published in 2024 1.
• Spontaneous bacterial peritonitis: IV albumin may be considered in patients with SBP, particularly those with AKI and/or jaundice, as it has been shown to reduce the risk of AKI and mortality, as evidenced by a recent meta-analysis published in 2024 1.
• Hepatorenal syndrome: IV albumin is beneficial in the treatment of hepatorenal syndrome, as it helps maintain intravascular volume and renal function, as supported by a study published in 2020 1.

Conclusion is not allowed, so the answer will continue without a conclusion section, and the references will be cited in the text as required.

The use of IV albumin in these specific conditions is supported by recent studies, including a meta-analysis published in 2024 1 and a study published in 2020 1, which demonstrated the benefits of IV albumin in reducing the risk of AKI and mortality in patients with SBP and hepatorenal syndrome. In contrast, oral albumin supplementation has no clinical utility, as proteins are broken down during digestion and do not directly increase serum albumin levels, as noted in a study published in 2024 1. Therefore, IV albumin should be used judiciously and only in specific conditions where its benefits have been established, as recommended by recent guidelines and expert reviews 1.

From the FDA Drug Label

Emergency Treatment of Hypovolemic Shock Plasbumin-25 is hyperoncotic and on intravenous infusion will expand the plasma volume by an additional amount, three to four times the volume actually administered, by withdrawing fluid from the interstitial spaces, provided the patient is normally hydrated interstitially or there is interstitial edema. Although Plasbumin-5 is to be preferred for the usual volume deficits, Plasbumin-25 with appropriate crystalloids may offer therapeutic advantages in oncotic deficits or in long-standing shock where treatment has been delayed. Burn Therapy ... Beyond 24 hours Plasbumin-25 can be used to maintain plasma colloid osmotic pressure. Hypoproteinemia With or Without Edema ... Treatment with Plasbumin-25 may be of value in such cases. The usual daily dose of albumin for adults is 50 to 75 g and for children 25 g.

The treatment with intravenous (IV) albumin is well supported for certain conditions, including:

• Hypovolemic shock: IV albumin can help expand plasma volume and support blood pressure.
• Burn therapy: IV albumin can help maintain plasma colloid osmotic pressure beyond 24 hours after a burn injury.
• Hypoproteinemia with or without edema: IV albumin may be of value in treating hypoproteinemia, although it is considered symptomatic or supportive unless the underlying pathology can be corrected. However, the use of oral (PO) albumin is not mentioned in the provided drug labels. 2 2

From the Research

Treatment with Intravenous (IV) or Oral (PO) Albumin

• The use of albumin in clinical practice is supported by various studies, with specific indications and guidelines for its administration 3, 4, 5.
• Albumin is commonly used for fluid replacement in plasmapheresis and liver diseases, including hepatorenal syndrome, spontaneous bacterial peritonitis, and large-volume paracentesis, with moderate to high quality of evidence and strong recommendations 3.
• In patients with cirrhosis, albumin administration is recommended for preventing and managing complications such as ascites, hepatic encephalopathy, and variceal bleeding, with evidence-based guidelines proposing its use in specific situations 4, 5.
• However, the use of albumin for other indications, such as hypovolemic shock, sepsis, and severe burns, has a low to moderate quality of evidence and weak recommendations 3.
• The administration of intravenous albumin to mitigate hypotension and augment ultrafiltration during kidney replacement therapy is controversial, with minimal data supporting its routine use 6.
• Restricting the use of albumin according to guidelines can lead to significant cost savings, as demonstrated by a study that resulted in a 50% reduction in albumin use and direct cost savings of approximately $100,000 7.

Indications for Albumin Administration

• Liver disease, including hepatorenal syndrome, spontaneous bacterial peritonitis, and large-volume paracentesis 3, 4, 5
• Cirrhosis complications, such as ascites, hepatic encephalopathy, and variceal bleeding 4, 5
• Fluid replacement in plasmapheresis 3
• Hypovolemic shock, sepsis, and severe burns (weak recommendations) 3
• Kidney replacement therapy (controversial) 6

Quality of Evidence and Recommendations

• Moderate to high quality of evidence and strong recommendations for liver disease and cirrhosis complications 3, 4, 5
• Low to moderate quality of evidence and weak recommendations for hypovolemic shock, sepsis, and severe burns 3
• Minimal data supporting the routine use of intravenous albumin for kidney replacement therapy 6
