BackgroundAdipose-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.MethodsWe 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 < 2 h/week and B) active, referring to low or moderate-intensity physical activities > 2 h/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.ResultsWith 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 ± 5.53 ng/ml vs 14.77 ± 8.48 ng/ml, p = 0.013), higher apelin (1.39 ± 0.65 ng/ml vs 1.04 ± 0.35 ng/ml, p = 0.018) and adiponectin (11.82 ± 3.06 μg/ml vs 7.81 ± 2.11 μg/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 (R2 = 0.328, p = 0.032), while physical activity was independently associated with apelin (R2 = 0.221, p = 0.022).ConclusionsSelf-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. 相似文献

There is adequate evidence that growth during the perinatal period is linked to the risk of several adult onset diseases, and recent findings indicate that the insulin-like growth factor (IGF) system is involved in prenatal growth, as reflected in birthweight. However, whether major components of the IGF system are involved in the immediate post-natal growth has not been studied. Maternal questionnaires were completed, and laboratory measurements of several variables, including IGF-I, IGF-II and IGF-binding protein-3 (IGFBP-3), were made for a total of 331 apparently healthy full-term newborns, from whom routine blood samples were taken during the first 5 days of their life. Birthweight and weight at the time of bleeding were among the recorded variables, and the difference divided by the age in days of the newborn was considered as reflecting immediate postnatal growth velocity. Immediate postnatal growth velocity was strongly positively associated with IGF-I. The squared adjusted correlation coefficient was 0.29 when IGF-I was incorporated in the model predicting postnatal growth velocity but was only 0.08 when IGF-I was excluded. In contrast, IGF-II and IGFBP-3 had no effect on postnatal growth velocity. It thus appears that IGF-I underlies growth during the immediate postnatal period. To the extent that perinatal growth may affect adult onset diseases, the findings of this study suggest that the action of IGF-I during the immediate postnatal period may represent a process of major importance. 相似文献
