Chest
Clinical InvestigationsCopdCatabolic/Anabolic Balance and Muscle Wasting in Patients With COPD
Section snippets
Subjects
The study population consisted of 45 men with COPD who were in stable condition, who had participated in our previous study6 evaluating the impact of low muscle mass on survival in COPD, and in whom blood was available for the quantification of anabolic and catabolic factors. The diagnosis of COPD was based on smoking history and on pulmonary function test results showing irreversible airflow limitation.21 Patients with any active inflammatory diseases as well as any other chronic diseases,
Results
The anthropometric characteristics of both subgroups of patients and control subjects are shown in Table 1. Twenty-seven patients with COPD had an MTCSA of ≥ 70 cm2 (86 ± 2 cm2), while the remaining 18 patients had an MTCSA of < 70 cm2 (58 ± 2 cm2). For comparison, the mean MTCSA in the 16 healthy individuals was 96 ± 4 cm2. Patients with an MTCSA of < 70 cm2 had a significantly lower BMI compared to patients with an MTCSA of ≥ 70 cm2 and subjects in the control group. The impairment in
Discussion
In this study, peripheral muscle atrophy was associated with disturbances in catabolism and anabolism and not with the level of impairment in lung function. Marked elevations of catabolic/anabolic factor ratios (ie, cortisol/DHEAS, IL-6/Tbio, IL-6/DHEAS, and IL-6/IGF-1), particularly in patients with COPD and low MTCSAs, indicate that there was a shift toward catabolism in COPD patients. Although none of the catabolic or anabolic factors were related to MTCSA, IL-6/DHEAS ratio, which is a

Neuroendocrine stress hormones associated with short-term exposure to nitrogen dioxide and fine particulate matter in individuals with and without chronic obstructive pulmonary disease: A panel study in Beijing, China
2022, Environmental PollutionCitation Excerpt :Because both patients with COPD and non-COPD participants were enrolled and followed up simultaneously in this panel study, we were able to compare their neuroendocrine responses to pollutant exposure. There were no significant differences in basal stress hormone levels between COPD and non-COPD participants (Table 2), which is consistent with previous studies (Debigaré et al., 2003; Karadag et al., 2008). In stratified analyses, we identified significant associations between air pollutant exposure and stress hormones in both subgroups (Fig. 3).

2019, Respiratory MedicineCitation Excerpt :This muscle weakness is a major issue as it has been associated with the increased use of health resources [3,4] and, more critically, it is a strong independent predictor of patient survival [5]. While, the muscle weakness was originally attributed to a peripheral muscle dysfunction due to reduced muscle mass, chronic inflammation and oxidative stress [2,6,7], a reduced motor command has been evidenced by decreased primary motor cortex activation in patients during both maximal and submaximal voluntary contractions, even without marked muscle atrophy [8–10]. Nevertheless, the pathways involved in this impaired motor drive remain unclear.
