Bronchitis Emedicine - Feline Asthma - Investigation and Treatment

Is quite common for cats to present to veterinary clinics with a chronic cough or wheeze. The problem may be constant or just recur from time to time, and can range from mild to severe. Clinically the disease may resemble human asthma, but the term feline asthma can be misleading as there are a number of different possible causes. Here we look at what those underlying causes can be, and the different forms of treatment available to affected cats. :idea:

Treatment Lifelong?

Generally yes. Doses can often be reduced gradually once clinical remission has been achieved. As with many chronic conditions, complete control might not always be possible and an acceptable quality of life is the main aim of the treatment. We are satisfied with this end product on Chronic Bronchitis. It was really worth the hard work and effort in writing so much on Chronic Bronchitis.

Bronchoscopy Bronchoscopy allows visualization of the larger airways, and assessment for increased mucus and inflammation. 4. Tracheal wash This involves injecting a small amount of saline into the trachea and immediately withdrawing it, and then examining the cells and debris harvested under a microscope.

Aerosol therapy has the advantage that the maximum concentration of drug is delivered to the target site. This means that lower overall doses can be used, and the cat is less likely to suffer the negative side effects of steroids. Various inhalers can be used in both cats and dogs, but they tend to be designed for humans. As a result, higher doses are given compared with human medicine, as humans can be instructed to breathe deeply whereas cats will breathe normally at best.

The Differentials

There are a large number of possible diagnoses when a cat first presents with coughing or breathing difficulty. Here are some of the more important ones: Enhancing your vocabulary is our intention with the writing of this article on Chronic Bronchitis. We have used new and interesting words to achieve this.

Cats usually present with one or all the following signs: CoughingWheezingDifficulty breathing A minority of cases will have the classic human status asthmaticus, rapid onset breathing difficulty due to severe narrowing of the bronchi. Cats tend to be middle aged or older, and Siamese cats may be more prone than other breeds. We have not included any imaginary or false information on Infectious Bronchitis here. Everything here is true and up to the mark!

Bronchodilator drugs used in inhalers include Salbutamol and Salmeterol. Salbutamol is very fast acting and therefore useful in a crisis caused by spasm of the bronchi. However, it only lasts for about 30 minutes and is therefore unsuitable for chronic therapy as frequent dosing is required. Salmeterol on the other hand is longer acting, and lasts for about 12 hours so twice daily dosing is possible. Salmeterol is better for long term control of mild to moderate asthma while Salbutamol is better for relief of acute bronchospasm. Using our imagination has helped us create a wonderful article on Infectious Bronchitis. Being imaginative is indeed very important when writing about Infectious Bronchitis!

Spacer Devices

A spacer device consists of a chamber into which the aerosol drug is released at one end, with a mask at the other end which fits snugly over the cats mouth and nose. Human baby spacer devices (e.g. Babyhaler) can be easily adapted for cats. Alternatively, veterinary spacers specifically designed for cats are now on the market (e.g. Aerokat). The spacer should be held over the cats nose and mouth for about 30 seconds to ensure complete delivery of the drugs. It should be remembered that aerosol steroid therapy can take up to 2 weeks to reach full effect, and if the cat has been on oral steroids previously, these should be phased out slowly during these initial 2 weeks. Aiming high is our motto when writing about any topic. In this way, we tend to add whatever matter there is about Infectious Bronchitis, rather than drop any topic. :oops:

Glucocorticoid drugs (steroids) used in inhalers include Beclometasone, Fluticasone and Budesonide. Beclometasone is cheap, but is rapidly absorbed into the bloodstream when you want it to hang around in the area where it applied. Fluticasone is more expensive, but tends to stay where you want it to. Budesonide is relatively inexpensive and though it is easily absorbed into the bloodstream, it tends to be removed the first time it goes through the liver. Even the beginner will get to learn more about Bronchitis after reading this article. It is written in easy language so that everyone will be able to understand it. :idea:

Lung Biopsy

This is an invasive procedure that carries a significant risk to the patient. It is only indicated where diffuse cancer or extensive fibrosis is suspected, or in severe disease that responds poorly to treatment. Suppressing our knowledge on Chronic Bronchitis is not our intention here. In fact, we mean to let everyone know more about Chronic Bronchitis after reading this!

Pulmonary Edema

Often due to severe heart disease.Infectious bronchitis. This can be due to bacteria, viruses or parasites.Pleural disease. Filling of the space between the lung and the chest wall with air or an effusion.Cancer. This can be a primary lung tumor or metastatic spread.Potassium bromide induced respiratory disease. A side effect from an anti-epileptic drug.Idiopathic pulmonary fibrosis. Responds poorly to treatment.Pulmonary thromboembolus. Lodging of a clot in a respiratory blood vessel causing sudden onset breathing difficulty.Pulmonary hypertension. Usually secondary to other heart or respiratory disease.

Remove or Avoid Airway Irritants

The most obvious one is ensuring the cat has no contact with cigarette smoke, and purchasing dust free cat litter. This is a dependable source of information on Chronic Bronchitis. All that has to be done to verify its authenticity is to read it!

The Pathology

Little is known about the underlying causes or exacerbating factors in feline asthma. There may be an element of genetic predisposition. While chronic inhalation of airway irritants, such as smoking, has been shown to cause bronchitis in humans, this has not been studied in detail in cats. Likewise, allergens such as pollen, housedust mites, dander, fungal spores, dust and cat litter could all be implicated theoretically. We have avoided adding flimsy points on Bronchitis, as we find that the addition of such points have no effect on Bronchitis.

Treatment The aims of treatment are as follows. 1. Eliminate any suspected infectious agents. This may be a sufficiently long course of antibiotics if bacterial infection is suspected, or a wormer such as fenbendazole if lungworm is suspected. :o.

Diagnosis 1. Clinical examination The first step in the diagnostic protocol is a thorough clinical examination by a veterinarian. This should localize the origin of the disease to the upper airways, lower airways or pleural space. If the cat is found to have pleural disease, a needle may be inserted straight away to remove either air or a sample of the effusion for both diagnosis and short term treatment of the respiratory distress. We have included some fresh and interesting information on Chronic Bronchitis. In this way, you are updated on the developments of Chronic Bronchitis. :shock:

  • Radiography The next test performed is usually thoracic radiography.
  • This is best performed under general anesthetic so there is lee chance for motion blur, though in acute situations this is not possible.
  • This is where the most meaningful information can be gained.
  • We cannot be blamed if you find any other article resembling the matter we have written here about Infectious Bronchitis.
  • What we have done here is our copyright material! :idea:

Removal or avoidance of potential allergens. House dust mite allergy must be excluded by spraying the house with an acaricidal product. 4. Chronic therapy for the underlying condition. For long term treatment of cats with feline asthma, a combination of steroids and bronchodilators are a popular choice. Steroids reduce the inflammation and lower mucus production, and can limit long term consequences such as fibrosis. Bronchodilators are most useful when there is airway spasm. Traditionally, medication has been given orally via tablets, but over the last few years, metered dose inhalers such as the ones used for human asthma have come on the market. It was with keen interest that we got about to writing on Infectious Bronchitis. Hope you read and appreciate it with equal interest.

To return to the comparison with human asthma, when trying to understand the underlying causes it is important to differentiate between asthma (constriction of the bronchi), chronic bronchitis (oversecretion of mucus with a chronic cough) and COPD (chronic obstructive pulmonary disease). Asthma is reversible bronchial constriction caused by eosinophil cells, whereas COPD is irreversible bronchial constriction involving neutrophil cells. It was our decision to write so much on Chronic Bronchitis after finding out that there is still so much to learn on Chronic Bronchitis.

Bronchoalveolar Lavage

This is similar to the technique described above, but the catheter is inserted all the way into a lower airway before the saline is injected and withdrawn. This is therefore a good test for lower airway disease. It may take some time to comprehend the matter on Infectious Bronchitis that we have listed here. However, it is only through it's complete comprehension would you get the right picture of Infectious Bronchitis.
