Acid-base disturbances in liver disease.

Area of Science:

• Hepatology
• Physiology
• Biochemistry

Background:

• The liver plays a crucial role in maintaining normal acid-base homeostasis.
• Hepatic dysfunction can lead to significant alterations in the body's acid-base status.
• Understanding these interactions is vital for managing liver disease patients.

Purpose of the Study:

• To elucidate the multifaceted relationship between liver function and acid-base balance.
• To highlight the liver's role in both normal homeostasis and pathological acid-base disturbances.
• To discuss how liver disease and its treatment can complicate acid-base status.

Main Methods:

• Review of physiological and metabolic functions of the liver related to acid-base balance.
• Analysis of pathogenetic mechanisms leading to hydrogen ion overproduction in liver conditions.
• Examination of acid-base disturbances associated with various liver diseases and therapeutic interventions.

Main Results:

• The liver influences acid-base balance through metabolism of amino acids and organic anions like lactate.
• Accelerated ketogenesis and lactate production during hepatic hypoxia can generate excessive hydrogen ions.
• Liver diseases, both acute and chronic, frequently present with complex acid-base disturbances.
• Therapeutic interventions for liver conditions, such as diuretics, can precipitate acid-base disorders.

Conclusions:

• The liver is a key regulator of acid-base homeostasis, influencing it through metabolic activities.
• Liver dysfunction can result in life-threatening acid-base imbalances, including lactic acidosis and metabolic alkalosis.
• Comprehensive management of liver disease requires careful monitoring and correction of associated acid-base disturbances.
