Dysregulated adipokine metabolism in chronic obstructive pulmonary disease.
BACKGROUND
Research concerning the involvement of body composition and systemic inflammatory markers in adipokine metabolism in chronic obstructive pulmonary disease (COPD) is still limited. Therefore, we primarily aimed to investigate the adipokine metabolism in relation to these systemic inflammatory biomarkers and to evaluate possible gender-related differences in the adipokine metabolism in patients with COPD.


METHODS
One hundred and eighty-six subjects with COPD [mean (SD) FEV(1) %pred: 50 (±16)] and 113 controls, matched for age, gender and body composition were selected from the ECLIPSE cohort. The following serological data were collected: serum levels of leptin, adiponectin and systemic inflammatory biomarkers such as C-reactive protein (CRP), Interleukin-6 (IL-6) and fibrinogen.


RESULTS
Compared with controls, patients with COPD had higher levels of CRP, IL-6, fibrinogen and adiponectin. After stratification for gender, men with COPD had higher CRP, IL6 and fibrinogen levels compared with male controls, while women with COPD had higher levels of CRP and fibrinogen compared with the female controls. Moreover, in both female controls and patients with COPD, leptin correlated with CRP and fibrinogen, while leptin only correlated with CRP in male controls. Adiponectin correlated negatively with CRP, only in patients with COPD. Body mass index and gender were the strongest determinants for both leptin and adiponectin.


CONCLUSIONS
This study shows a gender-dependent dysregulation of adipokine metabolism in patients with COPD compared with BMI-matched controls. Furthermore, results from this study suggest a more prominent role of adiponectin in the systemic response to COPD.
