Study Notes
Human Albumin Administration
- Human albumin administration is a common practice in clinical settings, but the optimal cutoff for its use is still uncertain.
- Two important outcomes of not having an albumin cutoff are earlier death and carriage of transfusion-related infections.
Hypoalbuminemia
- Hypoalbuminemia is a common condition with various health consequences, including:
- Loss of muscle mass during illness
- Increased risk of critical care admission
- Need for renal replacement therapy
- Increased red cell units and longer critical care stay
- Hypoalbuminemia is linked to the plasma volume expander and oncotic effects of albumin.
Albumin Function
- Albumin is a plasma volume expander with an additional albumin synthesis stimulating effect.
- The total-body albumin pool is approximately 390 g in a normal adult.
- There is a rapid exchange of albumin between intravascular and extravascular spaces (around 10 g/h).
Background and Rationale
- Human serum albumin (HSA) levels decrease in patients with cirrhosis of the liver, chronic nephrotic syndrome, and acute heart failure.
- HSA is supplied externally in certain cases, such as in critically ill patients, those needing postoperative fluid resuscitation, and pediatric and elderly patients.
Significance of Human Albumin
- Human albumin has functional variations that make it suitable for various scenarios of use.
- HSA binds certain metallic ions, water hydrophobes, and anionic basis of resistance.
- HSA is used in various medical applications, including:
- Plasma-dependent studies
- Pinocytosis uptake
- Dense Warngobed Morphy
Human Serum Albumin (HSA) Structure and Function
- HSA is a 66.5 kDa protein synthesized in the liver cells.
- It has three homologous domains:
- Erythroid sequence (LAMS Hydrolase)
- Sea AA 60-17 for N-touch-and-carry acid bearings (NAC)
- Sea AA 405-429 for aliphatic retinal chromatographic acid bearings (Crypt91)
- HSA maintains the equilibrium between brackets and pressure in the vessel and ensures the pH.
- It has a half-life of 19 days and exerts long-term effects.
