Effect of Infection on Nutrient Metabolism

摘要

Acute clinical illness caused by an infectious process is typically characterized by a catabolic response, which includes loss of body weight, wasting of body protein, anorexia, increased metabolic rate, and negative nitrogen, potassium, phosphorous, magnesium, sulfur, and zinc balances. Part of the catabolic response can be reversed in laboratory animal models by providing an adequate supply of amino acid and calories via oral or intravenous route.
