Serum pseudocholinesterase (ChE) levels are clinically significant for assessing liver damage. Analysis of ChE isozymes helps identify familial variants, which can be linked to adverse reactions like succinylcholine apnea.

Area of Science:

  • Clinical Chemistry
  • Biochemistry

Background:

  • Serum pseudocholinesterase (ChE) levels are clinically significant indicators, particularly for chronic diffuse liver damage.
  • Standardized recommendations for serum ChE measurement are still under development by the Japan Society of Clinical Chemistry.
  • Cholinesterase isozyme analysis is crucial for identifying familial variants, not for determining enzyme origin.

Purpose of the Study:

  • To review the clinical significance of serum pseudocholinesterase (ChE) and its isozymes.
  • To discuss methods for ChE isozyme detection and their clinical applications.

Main Methods:

  • Review of existing literature and clinical guidelines regarding serum ChE.
  • Description of electrophoretic and inhibitory methods (dibucaine, fluoride) for ChE isozyme analysis.

Main Results:

  • Decreased serum ChE levels sensitively reflect chronic diffuse liver damage.
  • Familial ChE variants are associated with succinylcholine apnea, especially in cases of very low ChE activity.

Conclusions:

  • Serum ChE measurement is valuable for liver disease assessment.
  • ChE isozyme analysis is essential for diagnosing familial variants linked to anesthetic complications.
