Bronchitis Cause Asthma: Bronchitis Cause Asthma
Some people with asthma rarely expertise symptoms, typically in response to triggers, whereas others may have symptoms that are marked and persistent. Many environmental factors are associated with asthma's development and exacerbation including allergens, air pollution, and other environmental compounds. Low air quality from variables including ozone levels that were high or traffic pollution, continues to be connected with both asthma development and increased asthma severity. Certain viral respiratory infections, such as rhinovirus and respiratory syncytial virus, may boost the risk of developing asthma when acquired as young children. The strongest risk factor for developing asthma is a history of atopic disorder; with asthma occurring at a substantially greater rate in those who have either eczema or hay fever.
The study - led by Cardiff University in the UK - reveals for the very first time that 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 "unbelievably exciting," because for the first time they've linked airway inflammation - that may be triggered for example by cigarette smoke and car fumes - with airway twitchiness. She adds: "Our paper shows how these triggers release compounds that activate CaSR in airway tissue and drive asthma symptoms like airway twitchiness, inflammation, and narrowing.
Prof. Riccardi reasons: The researchers believe their findings about the function of CaSR in airway tissue could have significant consequences for other respiratory ailments 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 range of disorders including asthma, COPD, cystic fibrosis and even certain cancers.
The Disease Will Almost Always Go Away on Its Own Within 1 Week
He or she may prescribe antibiotics if your doctor believes you also have bacteria in your airways. This medicine will only get rid of bacteria, not viruses. Occasionally, bacteria may infect the airways along with the virus. You may be prescribed antibiotics if your doctor believes this has happened. Occasionally, corticosteroid medicine can also be needed to reduce inflammation in the lungs.

Asthmatic Bronchitis Symptoms, Causes, Treatments
Acute bronchitis is a respiratory disease that triggers inflammation in the bronchi, the passageways that move air into and from the lungs. If you have asthma, your risk of acute bronchitis is raised due to an increased sensitivity to airway inflammation and irritation. Treatment for asthmatic bronchitis includes antibiotics, bronchodilators, anti-inflammatory drugs, and pulmonary hygiene techniques including chest percussion (medical treatment in which a respiratory therapist pounds gently on the patient's torso) and postural drainage (medical treatment when the patient is placed in a somewhat inverted position to boost the expectoration of sputum).
Acute Exacerbations of Chronic Bronchitis Acute exacerbations of chronic bronchitis (AECB) is a condition characterized by an increase in the frequency and severity of the symptoms of chronic bronchitis. Bronchitis is brought on by the inflammation of the bronchi or air passages of the...
With the most common organism being Mycoplasma pneumoniae only a small portion of acute bronchitis illnesses are caused by nonviral agents. Study findings suggest that Chlamydia pneumoniae may be another nonviral cause of acute bronchitis. The obstructive symptoms of acute bronchitis, as determined by spirometric studies, have become similar to those of mild asthma. In one study. Forced expiratory volume in one second (FEV), mean forced expiratory flow during the midst of forced vital capacity (FEF) and peak flow values fell to less than 80 percent of the predicted values in nearly 60 percent of patients during episodes of acute bronchitis.
Recent Epidemiologic Findings of Serologic Evidence of C
Pneumoniae infection in adults with new-onset asthma imply that untreated chlamydial infections may have a role in the transition from the intense inflammation of bronchitis to the long-term inflammatory changes of asthma. Patients with acute bronchitis usually have a viral respiratory infection with passing inflammatory changes that produce symptoms and sputum of airway obstruction. Evidence of reversible airway obstruction even when not infected Symptoms worse during the work week but have a tendency to improve during weekends, holidays and vacations Persistent cough with sputum production on a daily basis for at least three months Upper airway inflammation and no signs of bronchial wheezing Signs of infiltrate on the chest radiograph Signs of increased interstitial or alveolar fluid on the chest radiograph Generally related to a precipitating event, such as smoke inhalation Signs of reversible airway obstruction even when not infected Symptoms worse during the work week but tend to improve during weekends, holidays and vacations Chronic cough with sputum production on a daily basis for a minimum of three months Upper airway inflammation and no signs of bronchial wheezing Signs of infiltrate on the chest radiograph Signs of increased interstitial or alveolar fluid on the chest radiograph Generally related to a precipitating event, including smoke inhalation Asthma and allergic bronchospastic disorders, for example allergic aspergillosis or bronchospasm due to other environmental and occupational exposures, can mimic the productive cough of acute bronchitis.
Cat Asthma Symptoms, Wheezing, Treatments, and Breeds
These passageways constrict and thicken, making it very difficult for a cat to breathe when an asthma attack happens. Because asthma can fast become a life-threatening health problem, a veterinary evaluation is needed by any cat that is coughing. It's thought to grow as an outcome of allergic bronchitis, while there are several factors that give rise to asthma in cats. Allergic bronchitis occurs when the airways in a cat's lungs become inflamed due to other substance that stimulates the immune system or an inhaled allergen. Common factors that can bring about the severity of an asthma attack include: Asthma-like symptoms in cats can also be related to other disorder, including respiratory parasites, heartworm, tumors, heart failure and pneumonia. If you think your cat has asthma visit your veterinarian promptly.
