What Is Bronchitis Caused By: Bronchitis Causes

What is Bronchitis?
Bronchitis (bronKItis) is a condition where the bronchial tubes become inflamed. Both main types of bronchitis are acute (short term) and chronic (ongoing). Chronic bronchitis is a serious, long term medical condition.
Most People With Chronic Bronchitis Have Chronic Obstructive Pulmonary Disease (COPD)
Tobacco smoking is the most common cause, with a number of other factors for example air pollution and genetics and a smaller part playing. Symptoms of chronic bronchitis may include wheezing and shortness of breath, especially upon exertion and low oxygen saturations. Most cases of chronic bronchitis are caused by smoking cigarettes or other forms of tobacco. Additionally, chronic inhalation of air pollution or irritating fumes or dust from hazardous exposures in vocations like livestock farming, grain handling, textile production, coal mining, and metal moulding may also be a risk factor for the development of chronic bronchitis. Unlike other common obstructive illnesses like asthma or emphysema, bronchitis seldom causes a high residual volume (the volume of air remaining in the lungs after a maximal exhalation effort).

The study - led by Cardiff University in the UK - reveals for the first time the calcium-sensing receptor (CaSR) plays an integral part in causing the airway disease. Daniela Riccardi, principal investigator and a professor in Cardiff's School of Biosciences, describes their findings as "unbelievably exciting," because for the first time they have linked airway inflammation - which can be triggered for example by cigarette smoke and car fumes - with airway twitchiness. She adds: "Our paper shows how these triggers release substances that activate CaSR in airway tissue and drive asthma symptoms like airway twitchiness, inflammation, and narrowing.
Prof. Riccardi concludes: The researchers believe their findings about the role of CaSR in airway tissue could have significant consequences for other respiratory conditions such as chronic obstructive pulmonary disease (COPD), chronic bronchitis. The researchers, from Washington University School of Medicine in St. Louis, believe their findings will lead to treatments for a variety of ailments including asthma, COPD, cystic fibrosis and even certain cancers.
