Conditions included in this umbrella term are:

  • chronic bronchitis
  • emphysema

Other names

COPD is also known as CORD, COAD, COLD which respectively stand for chronic obstructive respiratory, airways, or lung disease. COPD has been referred to as CAL which stands for chronic airway limitation.

Working definition

COPD is a chronic, progressive disorder related to tobacco abuse and characterized by airways obstruction (FEV1 <80% predicted and FEV1 / VC ratio <70%).

The Global Initiative for Chronic Obstructive Lung Disease (GOLD) defines COPD as "a disease state characterized by airflow limitation that is not fully reversible. The airflow limitation is usually progressive and associated with abnormal inflammatory response of the lungs to noxious particles or gases."

Causes

The main risk factor in the development of COPD is smoking. Approximately 15% of all chronic smokers will develop the disease. In susceptible people, this causes chronic inflammation of the bronchi and eventual airway obstruction. Other etiologies include alpha 1-antitrypsin deficiency (augmented by smoking), byssinosis, and idiopathic disease.

Among people over 70 who have never smoked, women make up 85 percent of those with COPD. This appears to be tied to decreases in estrogen as women age. Female mice that had their ovaries removed to deprive them of estrogen lost 45 percent of their working alveoli from their lungs. Upon receiving estrogen, the mice recovered full lung function. Two proteins that are activated by estrogen play distinct roles in breathing. One protein builds new alveoli, the other stimulates the alveoli to expel carbon dioxide. Loss of estrogen hampered both functions in the test mice. (Massaro & Massaro, 2004).

Progression

COPD is a progressive disease. Obstructive changes in spirometry and decreases in diffusion capacity are typically seen before symptoms occur. Early signs and symptoms are shortness of breath on exertion, recurrent respiratory infections or a morning cough. As the disease continues, the symptoms are seen with increased frequency and severity. In the late stages, the patient often experiences severe cough, constant wheezing, and shortness of breath with minimal exertion or rest. At this late stage, progression to respiratory failure and death is common. Progression is typically caused by the patient's continued exposure to tobacco smoke. Although medications often decrease symptoms, it is not believed that they prevent the progression if the patient continues to smoke.

Clinical Management of Chronic Obstructive Pulmonary Disease - Lung Biology in Health and Disease, Volume 165 - Book Review
From CHEST, 6/1/03 by Ashok Shah

By Thomas Similowski, William A. Whitelaw, Jean-Philippe Derenne, eds. New York, NY: Marcel Dekker, 2002, 1072 pp; $250

COPD is currently the sixth-leading cause of death worldwide, and it has been estimated that it will climb to the third spot by 2020. Current treatment is, without doubt, unsatisfactory; in spite of the recent Global Initiative on Chronic Obstructive Lung Diseases guidelines, a nihilistic approach is often adopted. The very fact that nearly 1,100 pages are required for Clinical Management of Chronic Obstructive Pulmonary Disease reflects on the far-from-happy situation that we are in today. Having said that, this brilliant and decidedly valuable tome systematically takes the reader from diagnosis through management, and includes a panoramic view of the approach to management throughout the globe.

Three distinguished editors have succeeded in recruiting recognized experts from all over the world to present up-to-date and well-established information that can easily be assimilated by the reader. This elegantly structured book has 10 parts, which have further been subdivided into 45 chapters. The first part, centered on diagnosis and follow-up, comprises 10 chapters that systematically acquaint the reader with the clinical approach to a patient with COPD. The diagnostic aspects include essential investigations such as pulmonary function and imaging, while the follow-up section contains information ranging from assessment and management of dyspnea to the impact of health-related quality of life studies in COPD, to disability evaluation. An entire chapter is included on treatment recommendations for the general practitioner.

A separate section explores treatment approaches based on the pathophysiology of COPD, including therapeutic perspectives on genetics and another on the role of antioxidant therapy. Pharmacologic therapy is covered in seven chapters, and not only deals with individual pharmacologic agents but also carries an innovative description of methodology for therapeutic trials in COPD. In addition to bronchodilators and steroids, the roles of other therapeutic strategies such as vasodilators, analeptics, and mucolytics are covered. Prevention of infection and management of associated conditions including lung cancer, anxiety, and depression and the effect of COPD on sleep are also described. Two chapters deal with the effect of COPD on the heart, an aspect that tends to be overlooked by pulmonologists. A section covering the influence of other factors, including the impact of respiratory muscle performance, nutrition, and physiotherapy, seeks to focus the reader's attention on facets other than just pharmacology. A section entitled "Instrumental Treatments" includes lucid and well-written reviews of oxygen therapy, noninvasive ventilation, and the role of tracheostomy, but in this case one gets a fleeting impression that there may have been a time lag between writing and publication. A concise account of the role of surgery in COPD is presented and includes worthwhile information on the current state of lung volume reduction surgery and lung transplantation. "Management of the COPD Patients Undergoing Surgery" guides the pulmonologist through the preoperative evaluation as well as postoperative treatment modalities.

A 21-page "must-read" section on future strategies lets us "gaze into the crystal ball" and gives us a glimpse of, and raises hope for the things to come; however, a separate section on acute exacerbation of COPD would have further enriched the book. The last part, comprising five chapters, gives us an overview of the different approaches to the management of COPD throughout the world. It carries a segment comparing the guidelines of different regional societies, and also highlights the importance that the World Health Organization assigns to this disease.

Clinical Management of Chronic Obstructive Pulmonary Disease is a well-compiled and comprehensive treatise that focuses on this enormous problem, and emphasizes the need to do much more. The Executive Editor (Claude Lenfant) and publishers of the Lung Biology in Health and Disease series, and the editors of this superb monograph should be applauded for this very timely effort, which will be of immense help to all students of this crippling disease.
