Severity Of The Disease

Background: Surfactant protein D (SP-D) is a lung-specific protein proposed to predict clinical outcomes in patients with chronic obstructive pulmonary disease (COPD). However, the changes in serum SP-D during acute exacerbation (AECOPD) episodes and the relationship of serum SP-D with the overall severity of the disease in stable COPD (SCOPD) remain unclear.Methods: Serum SP-D levels were analyzed in three groups, including AECOPD (n=40), SCOPD (n=71), and controls (n=60). In AECOPD group, serum SP-D levels were determined at 1, 5, 14, and 30 days post-exacerbation. In SCOPD group, BODE (body mass index, airflow obstruction, dyspnea, exercise capacity) index was evaluated for severity assessment.Results: Serum SP-D levels were sequentially elevated from the controls to the SCOPD, and then to the AECOPD (p< 0.001). During an AECOPD episode, the raised serum SP-D levels subsided at day 5 (p> 0.05), fell markedly at day 14 (p< 0.001), and continued to decline at day 30 (p< 0.001). Among patients with SCOPD, serum SP-D levels correlated positively with the BODE index (p< 0.01).Conclusions: The longitudinal changes in serum SP-D levels during an AECOPD episode suggest that SP-D may be a potential systemic biomarker for COPD exacerbation. The correlation of serum SP-D levels with the BODE index suggests that circulating SP-Ds can reflect the overall severity of SCOPD.

Background and aims: Fatigue is associated with longitudinal ratings of health in patients with chronic obstructive pulmonary disease (COPD). Although the degree of airflow obstruction is often used to grade disease severity in patients with COPD, multidimensional grading systems have recently been developed. The aim of this study was to investigate the relationship between perceived and actual fatigue level and multidimensional disease severity in patients with COPD. Materials and methods: Twenty-two patients with COPD (aged 52-74 years) took part in the study. Multidimensional disease severity was measured using the SAFE and BODE indices. Perceived fatigue was assessed using the Fatigue Severity Scale (FSS) and the Fatigue Impact Scale (FIS). Peripheral muscle endurance was evaluated using the number of sit-ups, squats, and modified push-ups that each patient could do. Results: Thirteen patients (59%) had severe fatigue, and their St George’s Respiratory Questionnaire scores were significantly higher (p < 0.05). The SAFE index score was significantly correlated with the number of sit-ups, number of squats, FSS score and FIS score (p < 0.05). The BODE index was signif- icantly associated with the numbers of sit-ups, squats and modified push-ups, and with the FSS and FIS scores (p < 0.05). Conclusions: Peripheral muscle endurance and fatigue perception in patients with COPD was related to multidimensional disease severity measured with both the SAFE and BODE indices. Improvements in perceived and actual fatigue levels may positively affect multidimensional disease severity and health status in COPD patients. Further research is needed to investigate the effects of fatigue perception and exercise training on patients with different stages of multidimensional COPD severity.

Abstract Background: Pulmonary rehabilitation (PR) is a well-established treatment for chronic obstructive pulmonary disease (COPD). The standard protocol for PR requires frequent hospital visits, which can be difficult for patients. We performed this study to assess whether unsupervised home-based PR (HBPR) is effective for patients with COPD.Methods: This investigation was a prospective cohort study. After assessing the outcome data, including the results of a COPD assessment test (CAT); the body mass index, airflow obstruction, dyspnea, and exercise capacity (BODE) index; a pulmonary function test; the modified Medical Research Council (mMRC) dyspnea scale; and the 6-min walking test (6MWT), specialists imparted education to patients about unsupervised HBPR. Patients who exercised more than three times per week were classified as the compliant group, and the others were categorized as the noncompliant group. Changes in the outcomes were compared between the compliant and noncompliant groups.Results: 41 patients were enrolled in this study. After 8 weeks of unsupervised HBPR, there were significant improvements in CAT scores, BODE index, and forced expiratory volume in 1 s among patients in the compliant group compared with those in the noncompliant group. Moreover, their CAT and mMRC scores improved significantly after 8 weeks compared with those at baseline. On the other hand, patients in the noncompliant group showed no significant improvement in any of the outcomes.Conclusions: Unsupervised HBPR can be effective for compliant patients with COPD. We recommend unsupervised HBPR for patients with COPD even when regular hospital visits for PR are not possible.Trial registration: NCT03754881
