Ascorbic acid deficiency in liver disease

A D Beattie, S Sherlock

    Gut
    |August 1, 1976
    PubMed
    Summary
    This summary is machine-generated.

    Patients with liver disease, particularly alcoholic liver disease and primary biliary cirrhosis, show reduced leucocyte ascorbic acid (LAA). Low LAA levels are linked to delayed drug metabolism, impacting treatment strategies for these conditions.

    Area of Science:

    • Biochemistry
    • Hepatology
    • Clinical Nutrition

    Background:

    • Leucocyte ascorbic acid (LAA) is a key indicator of vitamin C status.
    • Liver diseases, including alcoholic liver disease (ALD) and primary biliary cirrhosis (PBC), can affect nutrient metabolism.
    • The relationship between LAA levels and drug metabolism in liver disease patients requires further investigation.

    Purpose of the Study:

    • To assess leucocyte ascorbic acid (LAA) levels in patients with various liver diseases.
    • To investigate the correlation between LAA and liver disease severity, treatment, and drug metabolism.
    • To determine the clinical implications of LAA levels in liver disease management.

    Main Methods:

    • Measurement of LAA levels in 138 patients with liver disease.

  • Analysis of LAA in relation to specific liver conditions (ALD, PBC) and cholestyramine therapy.
  • Correlation analysis between LAA, liver ascorbic acid from biopsies, haematological indices, liver function tests, cholesterol, and antipyrine half-life.

    • Main Results:

    • Significantly reduced LAA levels were observed in patients with ALD (P<0.01) and PBC (P<0.05).
    • Cholestyramine therapy in PBC patients was associated with lower LAA levels (P<0.05).
    • Low LAA levels (<100 nM/10(8) WBC) correlated with significantly higher antipyrine half-lives (mean=28.3 h vs 18.6 h, P<0.05), indicating delayed drug metabolism.

    Conclusions:

    • Leucocyte ascorbic acid deficiency is prevalent in alcoholic liver disease and primary biliary cirrhosis.
    • Low LAA levels are associated with impaired hepatic drug metabolism, evidenced by increased antipyrine half-life.
    • Clinical consideration of LAA status is crucial for optimizing drug therapy in patients with ALD and PBC.
