Abstract/OtherAbstract:
BACKGROUND: Adipose-tissue derivatives, known as adipokines, have been involved in the inflammatory-mediated metabolic and cardiovascular disorders of type 2 diabetes mellitus (T2DM). This study examined the association between novel adipokines and self-reported physical activity, a potential anti-inflammatory mediator.
METHODS: We enrolled 247 men and women with T2DM, free from overt cardiovascular disease. Based on a physical activity questionnaire, patients were classified into groups: A) sedentary, who did not report any physical activity or reported light activities<2h/week and B) active, referring to low or moderate-intensity physical activities>2h/week. Among them, 88 patients were randomly selected to perform a cardiorespiratory ergocycle testing. Clinical parameters, glycemic and lipid profiles, HOMA-IR, and serum levels of visfatin, apelin, vaspin, ghrelin and adiponectin were assessed.
RESULTS: With the exception of fat-mass, our groups did not differ in anthropometric parameters and pharmaceutical regimen. Active patients showed ameliorated glucose regulation, HOMA-IR, hsCRP and exercise capacity compared to sedentary counterparts (p<0.01). Active rather than sedentary patients showed lower visfatin (10.16±5.53ng/ml vs 14.77±8.48ng/ml, p=0.013), higher apelin (1.39±0.65ng/ml vs 1.04±0.35ng/ml, p=0.018) and adiponectin (11.82±3.06μg/ml vs 7.81±2.11μg/ml, p=0.033) levels. There were non-significant differences in the rest of parameters between groups. After adjusting for age, sex and BMI, physical activity along with hsCRP and ghrelin remained independent determinants of visfatin levels (R(2)=0.328, p=0.032), while physical activity was independently associated with apelin (R(2)=0.221, p=0.022).
CONCLUSIONS: Self-controlled physical activity of, even, moderate intensity ameliorates adipokines, such as visfatin, apelin and adiponectin, in patients with T2DM. Prospective interventional studies will confirm our results. The ClinicalTrials.gov identifier is: NCT00306176.
