[Feline asthma and chronic bronchitis - an overview of diagnostics and therapy].

Feline asthma and feline chronic bronchitis are considered the most common chronic lower respiratory diseases in cats and are frequently referred to by the term chronic bronchial diseases. In feline asthma, a hypersensitivity reaction type I is suspected. For chronic bronchitis, the aetiology remains largely unknown. Affected cats may suffer from coughing, dyspnoea, and increased respiratory sounds. Both conditions are currently defined by the cytological cell pattern in the bronchoalveolar lavage and may differ in ethology, treatment, and clinical course. For diagnosis, other underlying conditions must be ruled out, in combination with the evidence for non-bacterial, eosinophilic or neutrophilic airway inflammation. In addition to the established therapy with oral or inhaled glucocorticoids and bronchodilators, the article also presents newer therapeutic and diagnostic options.
