Objective: Chronic obstructive pulmonary disease (COPD) is often associated with sarcopenia, and systemic inflammation is an underlying pathogenesis of COPD. In this study, the effects of interleukin (IL)- 6 and IL-10 levels on sarcopenia in patients with COPD were investigated.
Methods: Seventy-three patients (59 males and 14 females), aged 60– 93 years old, who had stable COPD (not including patients with advanced lung decline) were enrolled in this study. The patients were classified according to four stages of lung function, based on the Global Initiative for Chronic Obstructive Lung Disease 2018, and their symptoms were evaluated using the COPD assessment test and mMRC dyspnea Scale. The skeletal muscle index (SMI) was evaluated using a dual-energy X-ray absorptiometry test, and walking pace and handgrip strength were measured to reflect muscle mass and function. The diagnosis of sarcopenia was made according to the Asian Working Group for Sarcopenia and China guide recommendations. The inflammation biomarkers IL-6 and IL-10 were measured by enzyme-linked immunosorbent assay. Albumin (Alb) was measured using the bromocresol green method.
Results: Twenty-eight patients (38.36%) were diagnosed with sarcopenia. IL-6 (r = − 0.38, P = 0.001) and IL-10 (r = − 0.38, P = 0.001) were negatively correlated with the SMI, while the IL-10/IL-6 ratio had no correlation with sarcopenia. Multiple regression analysis showed that age (OR = 1.11, P = 0.02) and IL-6 (OR = 1.07, P< 0.05), had a strong correlation with sarcopenia, while IL-10 was not statistically significant in sarcopenia. However, body mass index (OR = 0.54, P = 0.002) had an opposite effect on muscle reduction.
Conclusion: The increase of IL-6 might be a factor associated with sarcopenia. However, the relationship between IL-10 and sarcopenia is unclear.
