    Author: Shin HY, Park S, Lee JW.
    Journal: Endocr Res; 2017 Nov; 42(4):287-295. PubMed ID: 28323510.
    Abstract:
    PURPOSE: Adiponectin and chemerin have been reported their associations with insulin resistance and chronic inflammation. However, the relationship between adiponectin and chemerin themselves has not been fully elucidated. Therefore, we investigated the effects of changes in adiponectin and chemerin levels after a weight intervention. MATERIALS AND METHODS: We recruited 136 healthy overweight or obese subjects from 2006 to 2009 and provided all participants lifestyle modification therapy with diet consultations over 16 weeks. We assigned the participants to take orlistat or sibutramine or to a no prescription group. We analyzed the data using paired t-tests, Pearson's partial correlation analysis, and stepwise multiple linear regression analysis. RESULTS: ∆ in chemerin was positively correlated with ∆ in adiponectin (r = 0.29, p < 0.01), and these trends were similar in the insulin-resistant (r = 0.35, p = 0.03) and insulin-sensitive (r = 0.27, p < 0.01) groups. In multiple regression analyses, Δadiponectin, ΔQUICKI (quantitative insulin-sensitivity check index), Δglucose, and ΔDBP were significantly associated with Δchemerin in the insulin-resistant group, and initial chemerin level, ΔQUICKI, ΔBMI (body mass index), and taking orlistat were associated with Δchemerin in the insulin-sensitive group. CONCLUSIONS: Changes in chemerin levels were positively associated with changes in adiponectin levels. The association between these changes might be related to chemerin's dual inflammatory and anti-inflammatory effects or insulin resistance and insulin sensitivity enhancing effects, depending on the metabolic conditions. Additional studies are needed to clarify the mechanisms that underlie the effects of adiponectin and chemerin.
