Who Does Bronchitis Affect - Diseases of the Lung

---

Bronchitis is the inflammation of the bronchi, the main air passages to the lungs, it typically follows a viral respiratory infection. You must have a cough with mucus most days of the month for at least 3 months, to be diagnosed with chronic bronchitis. The symptoms of either kind of bronchitis include: Cough that produces mucus; if yellow green in color, you are more likely to have a bacterial disease Shortness of breath worsened by exertion or mild activity Even after acute bronchitis has cleared, you may have a dry, nagging cough that lingers for several weeks.

Bronchitis Causes

Acute bronchitis is usually brought on by viruses, typically the exact same viruses that cause colds and flu (influenza). Antibiotics don't kill viruses, so this type of medication isn't useless in most cases of bronchitis. The most common cause of chronic bronchitis is smoking cigs.

Acute upper respiratory tract infections (URTIs) include colds, flu and infections of the throat, nose or sinuses. Larger volume nasal washes and saline nose spray are becoming more popular as one of many treatment options for URTIs, and they have been shown to have some effectiveness for chronic sinusitis and nasal surgery that was following. This is a well conducted systematic review and the decision appears not false. See all (  Summaries for consumersCochrane authors reviewed the available evidence from randomised controlled trials on the use of antibiotics for adults with acute laryngitis. Acute upper respiratory tract infections (URTIs) comprise colds, influenza and diseases of the throat, nose or sinuses. This review found no evidence for or against the use of increased fluids in acute respiratory infections.

The study - led by Cardiff University in the UK - shows for the first time the calcium-sensing receptor (CaSR) plays a key role in causing the airway disease. Daniela Riccardi, principal investigator and a professor in Cardiff's School of Biosciences, describes their findings as "very exciting," because for the first time they've linked airway inflammation - which can be activated for example by cigarette smoke and car fumes - with airway twitchiness. She adds: "Our paper shows how these triggers release chemicals 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 purpose of CaSR in airway tissue could have important implications for other respiratory conditions such as chronic obstructive pulmonary disease (COPD), chronic bronchitis. The researchers, from Washington University School of Medicine in St. Louis, consider their findings will lead to treatments for a variety of ailments including asthma, COPD, cystic fibrosis and even certain cancers. People have an inclination of bragging on the knowledge they have on any particular project. However, we don't want to brag on what we know on who does bronchitis affect, so long as it proves useful to you, we are happy.

The association between atopic disease and the common acute bronchitis syndrome was examined using a retrospective, case control process. The charts of of a control group of 60 patients with irritable colon syndrome and 116 acute bronchitis patients were reviewed for evidence of preceding and subsequent atopic disease or asthma. Bronchitis patients were more likely to have a personal history or diagnosis of atopic disease a previous history of asthma, and more preceding and subsequent visits for acute bronchitis bronchitis. The main finding of the study was a tenfold increase in the following visit rate for asthma in the acute bronchitis group.

Asthma vs. COPD  There are two likely causes for this: you could have asthma, or you could have Chronic Obstructive Pulmonary Disease (COPD), like emphysema or chronic bronchitis. History of Smoking COPD is typically connected with a very long history of smoking, while asthma appears in nonsmokers as well as smokers. Smoking may also make asthma worse; and smokers are especially likely to suffer from a blend of asthma and COPD.

Asthmatic Bronchitis

---

Asthma and bronchitis are two inflammatory airway conditions. Acute bronchitis is an inflammation of the lining of the airways that usually resolves itself after running its course. When and acute bronchitis occur together, the condition is called asthmatic bronchitis. Asthmatic bronchitis that is common causes include: The symptoms of asthmatic bronchitis are a combination of the symptoms of bronchitis and asthma. You may experience some or all the following symptoms: You might wonder, is asthmatic bronchitis contagious? However, chronic asthmatic bronchitis generally isn't infectious.

Increased Exhaled Nitric Oxide in Chronic Bronchitis

---

Study goals: To examine the hypothesis that exhaled nitric oxide (NO) is increased in patients with chronic bronchitis, and to compare the outcomes with exhaled NO in patients with asthma and COPD. Among nonsmokers, the levels of exhaled NO were significantly higher in patients with chronic overcoming bronchitis and its health effects not in those with COPD when compared with either control group (patient management subjects; 11, outside control subjects). The greatest mean exhaled NO concentration occurred in patients with both chronic bronchitis and asthma vs control subjects). We consider that we have only touched the perimeter of information available on bronchitis compared to asthma. There is still a lot more to be learnt!
