Cytokines, the Acute-Phase Response, and Resting Energy Expenditure in Cachectic Patients with Pancreatic Cancer

Abstract

In pancreatic cancer at least a component of weight loss is due to increased REE. Furthermore, the presence of an acute-phase response identifies a group of patients who are markedly hypermetabolic. The serum concentration of TNF of IL-6 does not correlate with the presence of an acute-phase response, whereas rates of cytokine production by peripheral blood mononuclear cells are significantly greater in patients with such a response. This suggests that local rather than systemic cytokine production may be important in regulating the acute-phase response.
