Systemic Response to Injury and Metabolic Support Flashcards
(10 cards)
Interleukin that is a potent inducer of Acute phase patterns
IL 6
C-reactive protein
- Does not increase in reponse to stress in patients with liver failure
- do notshow diurnal variations
- not affected by feeding
- more sensitive than ESR
Inflammatory response response following traumatic injury
- The degree of inflammation is proportional toinjury severity
- independent predictor of subsequent organ dysfunction adn resultant mortality
- sterile
High-mobility group protein B1 (HMGB1)
- Best characterized DAMP, detectable in circulation within 30 minutes of trauma
- protein secretedby immune competent cells stimulated by PAMPs or inflammatory cytokines
- Also secreted by endothelial cells, platelets, and also as a part of cell death
Most Abundant amino acid in the human body
Glutamine (2/3 of the free intracellularamino acid pool)
Role of mitochondrialDAMPs in the injury mediated inflammatory response
Mitochondrial DNA and peptides from damaged mitochondria activate the macrophage inflammasome
major glucocorticoid in humans and is essential for survival during significant physiologic stress
Cortisol
Acts on the anterior pituitary to stimulate the secretion of ACTH into the systemic circulation
ACTH
Represents a Clinical syndrome highlighted largely by inadequate amounts of circulating cortisol and aldosterone
Adrenal Insufficiency
- described in patients with atrophic adrenal glands caused by steroid administration
- tachycardia, hypotension, weakness, nausea, vomiting, and fever
Nutritional formulas used to treat pulmonary failure typically increase the fat intake of apatient’s total caloric intake to
50%
- goal is to reduce carbon dioxide production
- with a corresponding reduction in carbohydrate content
