Are proteinase inhibitors a factor for the derangement of homoeostasis in protein-energy malnutrition?

In protein-energy malnutrition essential amino acids for the synthesis of proteins are derived from the mobilization of endogenous proteins in order to maintain homoeostasis. Data are presented to support the hypothesis that proteinase inhibitors, which increase rapidly at the onset of infection, interrupt this catabolic effect which is the normal adaptive response to protein-energy malnutrition.
