先前的研究已经发现呼吸困难和疼痛之间出乎意料的强烈联系,但原因仍不清楚。确定潜在的生物和心理机制可能会增强对这两种情况的理解,并提出新的治疗方法。我们试图阐明人口统计学因素、疾病严重程度、心理症状和生物标志物是否可能解释COPD患者疼痛和呼吸困难之间的相关性。我们分析了301例COPD患者的数据,这些患者在一项为期2年的前瞻性纵向观察性研究中接受了随访。测量包括自我报告的呼吸困难和疼痛,肺功能测试,血清炎症细胞因子水平,身体失调的措施,抑郁和焦虑量表。分析涉及横截面和纵向线性回归模型。疼痛和呼吸困难在横断面(r= 0.77,95% CI 0.72-0.82)和同时在时间(r= 0.42,95% CI 0.28-0.56)上具有强相关性。考虑到其他任何健康因素,也只是稍微减轻了这种关联。因此,疼痛和呼吸困难的症状可能与COPD有根本联系,而不是由常见的生物学、心理学或功能因素介导。从病人的角度来看,疼痛和呼吸困难可能是相同的基本经验的一部分。治疗一种疾病可能会改善另一种疾病。
Previous research has identified unexpectedly strong associations between dyspnea and pain, but the reasons remain unclear. Ascertaining the underlying biological and psychological mechanisms might enhance the understanding of the experience of both conditions, and suggest novel treatments. We sought to elucidate whether demographic factors, disease severity, psychological symptoms and biomarkers might account for the association between pain and dyspnea in individuals with COPD. We analyzed data from 301 patients with COPD who were followed in a prospective longitudinal observational study over 2 years. Measures included self-reported dyspnea and pain, pulmonary function tests, serum levels of inflammatory cytokines, measures of physical deconditioning, and scales for depression and anxiety. Analyses involved cross-sectional and longitudinal linear regression models. Pain and dyspnea were strongly correlated cross-sectionally (r= 0.77, 95% CI 0.72–0.82) and simultaneously across time (r= 0.42, 95% CI 0.28–0.56). Accounting for any of the other health factors only slightly mitigated the associations. Symptoms of pain and dyspnea thus may be fundamentally linked in COPD, rather than being mediated by common biological, psychological, or functional factors. From the patient’s perspective, pain and dyspnea may be part of the same essential experience. It is possible that treatments for one condition would improve the other.
