The pathogenesis of the nutritional
problems can be summed as follows:
- The chronic inflammation and ongoing
injury is a major form of stress, not unlike the healing decubitus ulcer.
- Cirrhosis leads to increased use of
alternative energy sources by the body, specifically fats.
- Decreased liver and pancreatic function
leads to poor GI absorption, particularly of fats and fat soluble
vitamins.
- Since there is poor fat absorption, this
fuel comes from endogenous sources, leading to a net catabolic state.
- Early satiety leads to poor oral intake,
further exasperating Mr. Bullroar's poor nutritional situation.
- In time there may even be problems of
carbohydrate intolerance leading to overt diabetes.
- There is often increased muscle
proteolysis, in an effort to
raise serum levels of specific amino acids.
- Leading to skeletal muscle wasting.
- Aromatic amino acids, phenylalanine,
tyrosine and tryptophan, increase disproportionately with rapid
muscle proteolysis.
- The imbalance between the serum
levels of aromatic and branched chain amino acids (leucine, valine
and isoleucine) is postulated to contribute to hepatic
encephalopathy of terminal cirrhotic patients.
Is there much hope for Mr. Bullroar? Unfortunately not a lot.
What can be done?
