[Plasma catecholamine levels in liver disease].

P Krauns, W Ruge

    Zeitschrift Fur Gastroenterologie
    |February 1, 1985
    PubMed
    Summary

    Plasma catecholamines, particularly norepinephrine, significantly increase in severe liver disease and hepatic coma. Epinephrine also elevates in advanced stages, indicating circulatory stress in acute and chronic liver conditions.

    Area of Science:

    • Biochemistry
    • Hepatology
    • Endocrinology

    Context:

    • Liver diseases, including cirrhosis and hepatitis, cause significant metabolic and circulatory disturbances.
    • Plasma catecholamine levels are crucial indicators of physiological stress and autonomic nervous system activity.
    • Understanding these alterations is vital for managing complications like hepatic encephalopathy and ascites.

    Purpose:

    • To investigate the changes in plasma catecholamine concentrations (norepinephrine, epinephrine, dopamine) in various chronic and acute liver diseases.
    • To correlate these catecholamine levels with the severity of liver disease and its complications, such as hepatic encephalopathy (grades 1-4), ascites, metabolic derangements, and circulatory alterations.

    Summary:

    • Norepinephrine levels were elevated in cirrhosis patients, peaking in hepatic coma (grade 4), and were also excessively high in fulminant hepatitis B.
    • Epinephrine concentrations showed significant increases in hepatic coma (grade 4) and fulminant hepatitis, but not in less severe cirrhosis without encephalopathy.
    • Dopamine levels were not detailed in the abstract's findings, while acute gestational fatty liver showed slight increases and fatty liver showed normal catecholamine levels.

    Impact:

    • This study highlights elevated norepinephrine as a key biomarker for severe liver disease and hepatic coma.
    • Findings suggest that catecholamine alterations are closely linked to the progression and severity of liver dysfunction and its associated complications.
    • The results provide insights into the pathophysiology of circulatory changes in liver disease, potentially guiding future therapeutic strategies.
