Canine chronic bronchitis and eosinophilic lung disease are inflammatory diseases characterized by cough for > 2 months without another identifiable cause. Dogs with chronic bronchitis have persistent airway neutrophilic inflammation. The foundation of long-term therapy is corticosteroids. Oral prednisone is commonly used but has a litany of possible adverse effects. Inhaled steroids is an alternative to avoid the adverse effects of prednisone but the only available option is fluticasone. This medication is expensive and has variable efficacy. Inhaled budesonide is a medication used in humans to treat a similar airway disorder and is a fraction of the cost. This study aims to investigate the benefit of inhaled budesonide on respiratory tract symptoms in dogs with inflammatory airway disorders.
About Chronic Bronchitis
Background
Canine chronic bronchitis, also known as chronic obstructive pulmonary disease (COPD), is a persistent respiratory condition in dogs characterized by inflamed and narrowed airways, leading to symptoms like chronic coughing, wheezing, and difficulty breathing. This condition is irreversible and tends to worsen over time. While it can't be cured, management involves medications like bronchodilators and anti-inflammatories, along with environmental adjustments to reduce irritants. With proper care, affected dogs can lead comfortable lives, though regular veterinary check-ups are essential to monitor the disease's progression and adjust treatment as necessary.
Eligibility
Dogs with a history of cough exceeding two months may be eligible for the study.
Thoracic radiographs will be used by principal investigator to determine eligibility.
Dogs with alternative caused for chronic cough such as tracheal collapse, heart disease, cancer, Valley Fever, etc are not eligible for this study.
Dogs who are currently receiving corticosteroids for treatment will be given consideration if they discontinue treatment before enrollment.
Compensation
Investigation of cough totaling $3,000 worth of diagnostic tests
Diagnostic tests including thoracic radiographs, CBC, chemistry, urinalysis, Valley Fever titers, bronchoscopy, and bronchoalveolar lavage. Fluid collected from the airways will be evaluated cytologically and various types of cultures (i.e., aerobic, anaerobic, Mycoplasma spp., and fungal).
Owner Responsibilities
Budesonide will be administered once every 12 hours at home with the owners for 14 days.
$400 service fees for initial screening
Owners will be instructed on how to administer inhaled budesonide with a nebulizer and mask that we provide. Budesonide will be administered once every 12 hours at home with the owners for 14 days.
Schedule
Administration of Budesonide every 12 hours
Repeat bronchoscopy at 14 days
A repeat bronchoscopy with bronchoalveolar lavage will be performed after 2 weeks of budesonide treatment. Budesonide treatment and repeat bronchoscopy will be free. Owners will be required to fill out short questionnaires to assess treatment response.
