Respiratory Overview

Respiratory medicine is the medical specialty that focuses on the study of the respiratory system, and on the diagnosis and the treatment of diseases of the lungs and bronchi.

In Europe, and worldwide, respiratory diseases are a leading cause of morbidity and mortality.1 Overall, in terms of incidence, prevalence, cost and mortality, they are placed second, behind cardiovascular disease.1 In 2003, the total financial cost of lung disease in Europe was estimated at 102 billion Euros.1 The most common respiratory diseases are; lung cancer, chronic obstructive pulmonary disease (COPD), asthma,...

... pneumonia, and tuberculosis.1

Asthma and COPD are the most common chronic respiratory diseases in adults in Europe.2 COPD is a set of chronic respiratory diseases affecting bronchial tubes, characterised by persistent obstruction of the airways, and accompanied by emphysema and/or chronic bronchitis.3 The prevalence of COPD is steadily rising worldwide due to the increased consumption of tobacco and an aging population.4

In 90% of cases, smoking is responsible for the development of respiratory diseases and thus represents the main risk factor.2 However, other factors appear to be involved but are insufficiently evaluated. These include; domestic and atmospheric pollution5, dietary habits6 and the level of physical activity.7 Studies are needed to understand the mechanisms involved, identify risk factors and genetic predisposition, and to develop new strategies for prevention and treatment of respiratory diseases, as in the case of COPD.8

COPD

Chronic Obstructive Pulmonary Disease (COPD) is a progressive disease of the respiratory system resulting in decreased lung function, which is a growing cause of morbidity and mortality worldwide. It has been estimated by The WHO Global Burden of Disease project that COPD was the fourth leading cause of death in 2004 and predicts that by 2030 it will be the third.1 However it is thought that the current prevalence is an underestimate, due to a lack of awareness among primary care physicians.

The three main symptoms of COPD are dyspnoea (breathlessness), cough and sputum production.2 In addition to these symptoms, many patients also experience mild to moderate pulmonary hypertension, cor pulmonale, weight loss and a general deterioration in their feeling of well-being.3-5

Diagnosis of COPD can be made using a combination of different methods; patient history, physical examination, airflow measurements, chest X-ray, and electrocardiogram.2

This progressive disease has no cure; however treatments for COPD are widely used to reduce the symptoms. Treatment guidelines outline the available treatments for specific stages of COPD.2

Cystic Fibrosis

COPD

Cystic Fibrosis (CF) is caused by a defect in a gene known as the cystic fibrosis transmembrane conductance regulator (CFTR) gene. This gene makes a protein that controls the movement of ions, such as chloride, and water, across cell membranes.1,2

CF is caused by hundreds of different gene mutations. The most common mutation is delta F508, usually written as ΔF508.3

Thick, sticky mucus causes most of the symptoms of CF. The most common symptoms of CF include:4

  • Persistent cough, often with phlegm
  • Frequent lung infections
  • Wheezing or shortness of breath
  • Very salty-tasting skin
  • Poor growth or weight gain despite a good appetite
  • Greasy, bulky, foul-smelling stools Stomach pain and discomfort caused by too much gas in the intestines
  • Dehydration

Because CF is a multisystem disease, treatment must be multidisciplinary, with a team of healthcare professionals providing comprehensive management of the patient.

Current therapy for CF is targeted at prevention and treatment of exacerbations. Care at the CF center includes inpatient as well as outpatient clinical care.5
