Basic Information image



Definition




• Inflammatory airway disease (IAD) is a respiratory disease of adult horses that is characterized by noninfectious inflammation of the small airways accompanied by airway hyperreactivity.


• It is not yet clear whether IAD is entirely a particulate-induced inflammation or if there is an allergic component to this disease.



Synonym(s)




• Small airway inflammatory disease


• Small airway disease


• Allergic airway disease



Epidemiology



Species, Age, Sex


Equine adults



Risk Factors


Stabling, a dusty environment, poor ventilation, high ambient endotoxin levels, high particulates of any kind



Geography and Seasonality


Seen more frequently in areas where horses are kept stabled and during months when horses are stabled



Clinical Presentation



Disease Forms/Subtypes




• Older horses may present with a more advanced form of disease that is more easily recognized as arising from the respiratory system.


• Younger horses may have much milder disease without distinct respiratory signs.



History, Chief Complaint




• Horses may present with variable cough, nasal discharge, exercise intolerance, poor recovery from work, and mild tachypnea.


• Dressage horses may be reluctant to come onto the bit. Racehorses may have no specific airway signs but may exhibit poor performance.



Physical Exam Findings




• Affected animals are usually in good flesh.


• There is no evidence of increased respiratory effort at rest. The horse may have a mildly elevated respiratory rate, serous to mucoid nasal discharge, and cough or may have no distinct respiratory signs. Loud bronchovesicular sounds or mild wheezes and crackles on auscultation of the chest and mild fluid noises on auscultation of the trachea may be heard.


• Horses are afebrile.
