Abstract
Background: Idiopathic chronic obstructive pulmonary disease (ICOPD) is a prevalent human disease. The etiology of the disease is yet to be clarified. The main aim of this project was to explore serum levels of interleukin-6 (IL-6), tumor necrosis factor-alpha (TNF-α) and transforming growth factor-beta (TGF-β) in the ICOPD patients in comparison to healthy controls.
Methods: In this cross-sectional study, serum levels of IL-6, TNF-α and TGF-β were evaluated in the 70 non-smoker ICOPD patients and 70 sex and age matched controls, using ELISA technique by the commercial kits from Karmania Pars Gene Company. Analysis of data was performed by parametric independent and Pearson correlation test.
Results: Serum levels of IL-6 and TGF-β, but not TNF-α, were significantly decreased in the ICOPD patients in comparison to controls. Serum levels of IL-6, TNF-α and TGF-β were not altered in the ICOPD male in comparison to female and also in mild when compared to moderate ICOPD patients.
Conclusions: Down-regulation of TGF-β may be the main risk factor for deterioration of inflammation in the ICOPD patients. Decreased IL-6 may be related to the idiopathic type of COPD.
