Twenty-five cases of feline bronchial disease (1995–2000)

Abstract

Twenty-five cases of feline bronchial disease were identified retrospectively. The criteria for inclusion were consistent clinical signs or histopathology and no other identifiable aetiology. Patient records were analysed to determine historical, clinical, clinicopathologic and radiographic features. The main presenting complaints were coughing and dyspnoea. The most common physical finding was dyspnoea. The majority of radiographs had a bronchial pattern either as the sole change or as a component of a mixed pattern. Bronchoalveolar lavage cytology was neutrophilic or eosinophilic in the majority of cats. There was no association between age, breed, sex, clinical signs, bronchoalveolar lavage cytology or radiographic severity and disease severity.

Radiographic abnormalities in cats with feline bronchial disease and intra- and interobserver variability in radiographic interpretation: 40 cases (1999–2006)

“…1,16 The right middle lung lobe is most susceptible to collapse, which may be attributable to the fact that the orientation and smaller size of its main bronchus could predispose it to mucus accumulation, resulting in obstruction. 2,3,7,11 Interestingly, lobar atelectasis was seen in only one of the cats with FBD in the present study and affected the right cranial lobe. 2,3,7,11 Interestingly, lobar atelectasis was seen in only one of the cats with FBD in the present study and affected the right cranial lobe.…”

“…1,2,5,6 Other radiographic features reported in cats with FBD include unstructured interstitial and alveolar patterns, lung hyperinflation and hyperlucency, and lobar atelectasis. [2][3][4]7 Furthermore, the intra-and interobserver variability in the radiographic assessment of this condition is unknown. 8 However, studies evaluating the relative prevalence of all radiographic signs in a large population of cats with FBD are lacking.…”

Influence of age on bronchoscopic findings in healthy beagle dogs

“…A scoring system was used to evaluate the bronchial, interstitial and alveolar patterns (Foster et al, 2004). The bronchial pattern was scored as: 0, absence of changes; 1, mild (primary bronchi visible); 2, moderate (secondary bronchi visible); 3, severe (tertiary bronchi visible).…”

Histopathologic and Morphometric Evaluation of the Nasal and Pulmonary Airways of Cats with Experimentally Induced Asthma

“…Features that define asthma in humans, including eosinophilic bronchial inflammation, spontaneous and reversible bronchoconstriction, smooth muscle hypertrophy, and mucus gland hyperplasia, are also hallmark features of naturally occurring asthma in cats [23,24,25]. The basis of these pathologic changes in both feline and human atopic asthma is believed to involve a type I hypersensitivity reaction to inhaled allergen that is characterized by a Th2 lymphocyte polarized response, promoting the morphologic changes in the pulmonary airways including tissue eosinophilia, goblet cell hyperplasia, epithelial cell and smooth muscle proliferation, subepithelial fibrosis, and mast cell accumulation [23,26,27].…”
