Abstract
Protein malnutrition is associated with a decreased febrile and acute phase response to infection and increased mortality. To elucidate a cause for this poor response, we assessed the effect of chronic protein malnutrition on monocyte production of the pyrogens interleukin-1 (IL-1) and tumor necrosis factor (TNF). Thirteen malnourished nursing home residents, 11 age-matched controls, and 9 young controls were studied. Production of IL-1 and TNF in vitro was not diminished in the malnourished group when compared with the age-matched and young controls. Causes other than diminished IL-1 or TNF production should be sought to explain decreased resistance to infection in the malnourished nursing home resident.
