Some studies suggested the effects of inflammatory cytokines in reducing muscle mass and muscle strength and, performance. This study aimed to compare pro-inflammatory cytokines in sarcopenic and non-sarcopenic subjects. 120 men and women were selected out from the cross-sectional study 'sarcopenia and its determinants among Iranian elders' (SARIR). Sarcopenia was defined based on the first 'European Working Group on sarcopenia in older people' (EWGSOP) guidelines. A fasting blood sample was taken from each participant to measure serum high-sensitivity C-reactive protein (hs-CRP), Interleukin 6 (IL-6), and tumor necrosis factor α (TNFα). A total of 120 participants were included in this study. Mean age was 66.7 ± 7.7 years and mean body mass index (BMI) was 27.3 ± 4.2 kg/m. Forty participants had the criteria of EWGSOP sarcopenia. A statistically significant difference was seen between normal and abnormal groups of muscle strength in hs-CRP (P-value = 0.04). Furthermore, we did not observe any remarkable association between inflammatory biomarkers including IL-6 (OR 1.15; 95% CI 0.31-4.28), TNF-α (OR 0.68; 95% CI 0.17-2.77), and hs-CRP (OR 2.39; 95% CI 0.87-6.55) and the presence of sarcopenia even after controlling for plausible confounders. We found that inflammatory biomarkers level was not associated with odds of sarcopenia. The lack of correlation between inflammatory cytokines and sarcopenia could be due to the participants' age and genetics. Future studies are required to confirm these findings.
一些研究表明,炎症细胞因子会减少肌肉质量和肌肉力量,并影响运动表现。本研究旨在比较肌少症和非肌少症患者的促炎细胞因子。从横断面研究“伊朗老年人肌少症及其决定因素”(SARIR)中选择了 120 名男性和女性。肌少症的定义基于第一个“欧洲老年人肌少症工作组”(EWGSOP)指南。从每位参与者抽取空腹血样,以测量血清高敏 C 反应蛋白(hs-CRP)、白细胞介素 6(IL-6)和肿瘤坏死因子 α(TNFα)。共有 120 名参与者纳入本研究。平均年龄为 66.7±7.7 岁,平均体重指数(BMI)为 27.3±4.2 kg/m2。40 名参与者符合 EWGSOP 肌少症标准。hs-CRP 在肌肉力量正常和异常组之间存在统计学差异(P 值=0.04)。此外,我们没有观察到炎症生物标志物(包括 IL-6、TNFα 和 hs-CRP)与肌少症之间存在显著关联,包括炎症生物标志物在内的任何标志物与肌少症的比值比(OR)分别为 1.15(95%CI 0.31-4.28)、0.68(95%CI 0.17-2.77)和 2.39(95%CI 0.87-6.55),即使在控制了可能的混杂因素后也是如此。我们发现炎症生物标志物水平与肌少症的几率无关。炎症细胞因子与肌少症之间缺乏相关性可能是由于参与者的年龄和遗传因素所致。需要进一步的研究来证实这些发现。
