Abstract

To assess the role of tumor necrosis factor (TNF) and interleukin-1 (IL-1) in the pathophysiology of cystic fibrosis (CF)-associated growth failure/cachexia and lung disease we measured height, weight, triceps skin fold, forced vital capacity, forced expiratory volume in 1 second, and plasma levels of TNF, interleukin-1-alpha (IL-1 alpha), interleukin-1-beta (IL-1 beta), and alpha-1-antitrypsin (A1AT) in 12 patients with CF, and in 12 age- and gender-matched healthy controls. The patients as a group had significantly lower values for the anthropomorphic measurements and lung function parameters as compared to controls. They also had higher circulating levels of A1AT than controls. TNF, however, was detected less frequently in patients than in controls. Neither group had detectable levels of circulating IL-1 alpha or IL-1 beta, which is consistent with the observation that CF patients infrequently present with fever. Potential explanations for these findings include compartmentalization of secreted TNF/IL-1, altered regulation of TNF/IL-1 secretion as a result of the chronic inflammatory state seen in CF, or increased degradation of TNF/IL-1, also a result of chronic inflammation. The role of these cytokines in the pathophysiology of CF remains unclear, but should be explored further; however it seems unlikely that circulating TNF plays a role in the growth failure/cachexia associated with CF.
