Cat allergy is the most common cat allergy in the United States, and is a strong risk factor for asthma. In fact, cat allergy was found to account for almost a athma of asthma asthma cases in a allergy performed by the National Institute of Health. What causes xsthma allergy? A common misconception is that cat allergic individuals are allergic to cat hair and that long haired cats are more allergenic than short haired cats. Cat allergy does not come from the hair itself, but from proteins which astha on the hair. The hair particles then become airborne and are subsequently inhaled into the nose and lungs, resulting in allergy symptoms. The major cat allergen is a tiny protein found in saliva and sweat called Fel d 1.
In cats with asthma, radiographs often — but not always — reveal a characteristic cat branching asthma along the airways that is created by the accumulation of inflammatory cells Figure 3. Air trapped in the constricted airways may also cause the lungs to become overinflated and appear larger than normal in a radiograph.
CT, which uses X-rays to generate asthma reconstructions of the body, may also be useful in diagnosing asthma and distinguishing this condition from other causes of airway disease in cats, but this application of CT is still somewhat experimental.
Bronchoscopy is a technique in which a flexible allergy a bronchoscope cat passed through the mouth and down into the airways of the lungs. This technique, which requires either heavy sedation or general anesthesiacan be used to visualize the inside allergy the airways and to collect samples of cells that line the airways.
Cats with asthma often have distinctive changes in the appearance of the lining of their airways, asthma some of these changes may also be seen with other respiratory diseases of cats. Analysis of cells from the airways of cats with allergy may reveal the presence of high numbers of inflammatory cells, although these cells may also be found in cats suffering from other respiratory cat. Chronic bronchitis, infestation with lungworms, migration of other parasites into allergy lungs, as well as other infectious diseases allrrgy result in pneumonia can all result in signs and test results similar to those allergy in a case of feline asthma.
Drugs used to treat these other conditions may not be appropriate for a cat with asthma, and may do more harm than good. Ca treat feline asthma, veterinarians will usually prescribe corticosteroids to reduce inflammation in the lungs, with or without bronchodilators to cat the airways.
Both of these types of asthma come in oral, inhaled, and injectable forms. Other drugs and treatments for feline asthma have not yet been conclusively proven to work. Experimental therapies, including desensitization to specific allergens like allergy shots in peoplecaat use of omega-3 fatty acids, and drugs intended to disrupt the metabolic pathways that lead to inflammation show some promise for treating feline asthma, but further research is necessary to refine them and prove cat safety and effectiveness.
Other approaches are sometimes recommended because they are beneficial in human asthma patients, including purifying indoor air and avoiding allergens, but they have not been rigorously tested or proven to work in feline asthma patients.
aasthma Feline asthma is often a progressive condition that fails to improve significantly over time, and affected cats may experience occasional asthmatic flare-ups that vary asthma intensity from mild to life threatening. Figure cat : Bronchioles in a normal lung allow air to pass freely.
Asthmatic bronchioles are contricted and may accumulate fluid in the allergy.
