This study aimed at determining whether airway responsiveness (AR) tests performed by use of barometric whole body plethysmography (BWBP) were repeatable in cats and to what extent AR was affected by the nebulization protocol used, the age of the animals, the inflammatory status of the airways and prior bronchodilator treatment. Repeatability of AR was tested on two occasions in 30 healthy cats. The concentration of carbachol inducing a 300% increase of the enhanced pause (Penh) - an estimator of airflow limitation - was calculated (C-Penh300) and did not differ significantly between the two tests (0.035 +/- 0.017% compared to 0.034 +/- 0.016%) and was significantly and positively correlated. The comparison between rapidly and slowly increasing carbachol concentrations was performed in ten healthy cats and showed a significantly lower C-Penh300 (%) when slowly increasing concentrations were used (0.037 +/- 0.013% compared to 0.039 +/- 10.015%, P < 0.05). A significant age-related increase of C-Penh300 was evidenced by performing AR tests in 15 healthy cats at 12, 18, 24 and 30 months (12 months: 0.026 +/- 0.008%, 18 months: 0.031 +/- 0.009%, 24 months: 0.038 +/- 0.01%, 30 months: 0.043 +/- 0.014%, P < 0.05). C-Penh300 significantly decreased in 12 Ascaris suum-sensitised cats after allergen exposure (0.026 +/- 0.016% compared to 0.033 +/- 0.016%, P < 0.05) and was negatively correlated with the granulocyte percentage of bronchoalveolar lavage fluid (r = -0.36, P < 0.01). Compared with a placebo inhalation, pretreatment with inhaled salbutamol significantly increased C-Penh300 in four healthy cats (0.093 +/- 0.021% compared to 0.036 +/- 0.004%, P < 0.05). This study provides evidence that AR determination by use of BWBP is promising as non-invasive indicator of lower airway inflammation or for monitoring response to bronchodilator treatment.

Thoracic radiography is an important diagnostic tool for feline respiratory medicine. The aim of this study was (1) to assess agerelated changes of thoracic radiographic views in healthy young cats and (2) to test if experimentally-induced bronchial inflammation by inhaling Ascaris suum (AS) allergens leads to radiographic changes after single or repeated exposures. Healthy cats (n = 15-30) aged between 6 and 30 months were evaluated. Eight healthy cats and eight AS-sensitised cats, respectively, inhaled sterile saline or allergen. Radiographs were taken 24 h before, and 6, 24 and 48 h after the challenge. Bronchoalveolar lavage (BAL) was performed after the last radiographic examination. AS-sensitised cats underwent three further allergen challenges at 3-month intervals. The radiographic evaluation was based on a scoring system considering bronchial, interstitial and alveolar patterns. A significant age-related increase in interstitial and total radiographic score was detected in healthy cats older than 18 months and in healthy cats older than 24 months. Whilst saline inhalation did not affect radiographic scores, a single AS challenge induced significant changes of all scores within 6-24 h. A significant positive correlation between radiographic scores and BAL neutrophils and eosinophils was found. Repeated AS challenges did not induce irreversible changes in radiographic scores.

The aims of this study were to characterise a model of feline allergic airway inflammation and to test through a longitudinal investigation whether five repeated allergen exposures would lead to signs of airway remodelling that would be detectable in vivo. Eight healthy control cats and eight cats sensitised with Ascaris suum allergens were investigated. Barometric whole body plethysmography (BWBP) was used for the assessment of respiratory variables and airway responsiveness (AR). Bronchoalveolar lavage fluid (BALF) was sampled for cytology and determination of F-2-isoprostane concentration and matrix metalloproteinase type 9 (MMP-9) activity. Thoracic radiography and bronchoscopy scores were also established. Cats were investigated prior to sensitisation and after inhalation of placebo or allergen challenge 1. BWBP measurements revealed a significant increase of enhanced pause (Penh), an index of bronchoconstriction, and AR in sensitised cats in response to allergen challenge 1. A significant increase in BALF neutrophil and eosinophil %, F-2-isoprostane concentration and MMP-9 activity, and increased radiography and bronchoscopy scores were recorded. After a recovery period of 6 weeks, all variables except BALF MMP-9 returned to baseline values. Four further allergen challenges induced similar changes to those seen in challenge I and no signs of persistent changes suggestive of bronchial remodelling were detectable. The model provides an in vivo approach to functional, inflammatory and morphological changes occurring in response to single and repeated allergen exposure. [less ▲]

Long-term outcomes with both treatment protocols were good, with half of the dogs being asymptomatic throughout the follow-up period. The remaining dogs showed mild clinical signs compatible with chronic rhinitis/sinusitis. These clinical signs were interpreted as chronic lymphoplasmacytic rhinitis/sinusitis and episodes of bacterial rather than fungal infection.

Idiopathic lymphoplasmacytic rhinitis (LPR) and sino-nasal aspergillosis (SNA) are among the most common causes of nasal discharge in dogs. The pathogenesis of both diseases is poorly understood. Some have proposed that LPR is a chronic inflammatory response to an inhaled irritant, pollutant or allergen, but others suggest that most cases of LPR constitute undiagnosed cases of SNA. Local immune dysfunction is thought to permit opportunist infection in canine SNA. This study investigates the nature of the local tissue immune response mounted in canine LPR and SNA in order to determine whether these diseases have similar or distinct pathogenesis. Quantitative reverse transcriptase polymerase chain reaction was carried out on RNA isolated from nasal biopsies from diseased and control dogs, using specific assays designed to amplify messenger RNA (mRNA), encoding a panel of cytokines and chemokines. SNA was associated with significantly increased expression of mRNA encoding interleukin (IL)-6, IL-8, IL-10, IL-12p19, IL-12p35, IL-12p40, IL-18, IFN-gamma, TNF-alpha, TGF-beta, eotaxin-2 and all four monocyte chemoattractant proteins (MCPs) relative to controls. LPR was associated with significantly increased expression of mRNA encoding IL-5, IL-8, IL-10, IL-12p19, IL12p40, IL-18, TNF-alpha, TGF-(3, MCP-2 and MCP-3 relative to controls. There was significantly more expression of mRNA encoding IL-6, IL-8, IL-10, IL-12p35, IL-12p40, IL-18, IFN-gamma, TNF-alpha, TGF-(3 and all MCPs, and significantly less expression of IL-5 in dogs with SNA than in dogs with LPR. Thus, the profile of cytokine and chemokine gene expression in the nasal mucosa is different in dogs with LPR when compared to dogs with SNA. A partial Th2 immune response appears to be mounted in the nasal mucosa of dogs with LPR, whereas the mucosal immune response in canine SNA is of the Th1 type. Increase in IL-10 and TGF-(3 transcripts in dogs with SNA is thought to be implicated in the failure to clear the Aspergillus infection. These results constitute the first evidence that the pathogenesis of canine LPR and SNA is distinct. (C) 2007 Elsevier B.V All rights reserved. [less ▲]

OBJECTIVES: To evaluate the effectiveness of rhinotomy and surgical debridement associated with topical administration of 2 per cent enilconazole and oral itraconazole in dogs with severe or recurrent sinonasal aspergillosis. METHODS: A standard rhinotomy was performed on seven dogs. In the initial study, the bone flap was left attached cranially and replaced at the end of the procedure. In the main study group, the bone flap was discarded. Nasal passages were debrided and irrigated with enilconazole solution for one hour. Oral itraconazole was administered to four dogs for one month postoperatively. Follow-up rhinoscopy was performed in all dogs. RESULTS: All three dogs in the initial study had recurrence of the disease and two dogs had a second surgery to remove the flap. The main study group included four dogs in which the flap was initially removed, and the two dogs from the initial study that required a second surgery. At follow-up rhinoscopy, five dogs were free of aspergillus but had bacterial or inflammatory rhinitis and one dog had a small aspergilloma but was subsequently asymptomatic. Telephone follow-up revealed that four dogs were asymptomatic, one dog had intermittent sneezing and serous nasal discharge, and one dog had intermittent epistaxis. CLINICAL SIGNIFICANCE: Rhinotomy with removal of the flap combined with one-hour infusion of 2 per cent enilconazole and oral itraconazole resulted in satisfactory outcome in dogs with severe or recurrent aspergillosis.
