Chronic obstructive pulmonary disease (COPD) is a common disability, largely encountered in the elderly population, in whom it causes significant morbidity and mortality. The general perception of health professionals is that COPD is often a self-inflicted disorder affecting the more socio-economically disadvantaged segment of the population with significant comorbidity. COPD is the least funded in terms of research in relation to illness burden compared with other chronic diseases. However, recently published guidelines of both the British Thoracic Society and the Global Initiative for Chronic Obstructive Lung Disease have highlighted best management strategies both of chronic symptoms and acute exacerbations in this patient group. The chronic management of COPD should, like asthma, involve a stepwise approach with smoking cessation being pivotal for all severities of COPD, regardless of patient age. The mainstay of therapeutic treatment remains regular bronchodilators, both beta(2)-adrenoreceptor agonists and anticholinergic agents. Current evidence suggests that long-acting beta(2)-adrenoreceptor agonists such as salmeterol and the new long-acting anticholinergic agent tiotropium bromide are more efficacious than their shorter acting equivalents such as salbutamol and ipratropium bromide in terms of bronchodilation, improved well-being and a reduction in acute exacerbation rates. Additionally since they are taken once or twice daily compliance should be improved. The role of long-term inhaled corticosteroids in the chronic management of COPD is contentious. Only those patients with COPD who have been shown to respond to a formal corticosteroid trial, preferably with a 2-week course of oral corticosteroid, should receive long-term inhaled corticosteroids. In the management of acute exacerbations in acidotic patients nasal ventilation is the treatment of choice in addition to conventional treatment with bronchodilators and oral corticosteroids. Antibacterials need not be prescribed universally in all exacerbations of COPD. Pulmonary rehabilitation classes either individually or in groups have been shown to be beneficial in the management of patients with COPD and their use in secondary care is to be encouraged. Most treatment modalities do not improve pulmonary function in patients with severe COPD. Therefore, pulmonary function including spirometry should be used to make the diagnosis of COPD but not as a monitor of efficacy of treatment. Assessment of severity of COPD and improvement with treatment modalities is best done with dynamic exercise testing such as 6-minute walk tests and incremental shuttle walk tests or with the administration of disease-specific physical disability and quality-of-life questionnaires. Most COPD research does not specifically target the older COPD patients and these patients may merit special consideration for their optimum assessment and management.
慢性阻塞性肺疾病(COPD)是一种常见的致残性疾病,多见于老年人群,会导致严重的发病率和死亡率。卫生专业人员的普遍看法是,COPD往往是一种自我造成的疾病,影响社会经济地位较低且合并症严重的人群。与其他慢性疾病相比,COPD在疾病负担方面获得的研究资金最少。然而,英国胸科学会和慢性阻塞性肺疾病全球倡议组织最近发布的指南都强调了该患者群体慢性症状和急性加重的最佳管理策略。COPD的慢性管理应像哮喘一样,采用逐步治疗方法,戒烟对所有严重程度的COPD患者都至关重要,无论患者年龄大小。治疗的主要手段仍然是定期使用支气管扩张剂,包括β₂肾上腺素能受体激动剂和抗胆碱能药物。目前的证据表明,长效β₂肾上腺素能受体激动剂如沙美特罗和新型长效抗胆碱能药物噻托溴铵在支气管扩张、改善健康状况和降低急性加重率方面比其短效同类药物如沙丁胺醇和异丙托溴铵更有效。此外,由于它们每天服用一到两次,依从性应该会提高。长期吸入性糖皮质激素在COPD慢性管理中的作用存在争议。只有那些被证明对正规糖皮质激素试验有反应的COPD患者,最好是接受为期2周的口服糖皮质激素治疗的患者,才应接受长期吸入性糖皮质激素治疗。在酸中毒患者急性加重的管理中,除了使用支气管扩张剂和口服糖皮质激素进行常规治疗外,鼻通气是首选治疗方法。并非所有COPD急性加重患者都需要普遍使用抗菌药物。已证明,单独或分组进行的肺康复课程对COPD患者的管理有益,应鼓励在二级医疗中使用。大多数治疗方式并不能改善重度COPD患者的肺功能。因此,肺功能检查(包括肺活量测定)应用于COPD的诊断,但不作为治疗效果的监测指标。评估COPD的严重程度以及治疗方式的改善情况,最好通过动态运动测试,如6分钟步行试验和递增往返步行试验,或通过使用特定疾病的身体残疾和生活质量问卷来进行。大多数COPD研究并未专门针对老年COPD患者,这些患者在进行最佳评估和管理时可能值得特别考虑。
