Relationship between surfactant alterations and severity of disease in horses with recurrent airway obstruction (RAO)
… and lines the respiratory epithelium of the airways. Phospholipids, the main component of surfactant, confer it its ability to lower surface tension and to prevent alveolar collapse. Airway surfactant helps maintain smaller airway patency, improves muco-ciliary clearance, decreases …

Biomarkers of oxidative stress and inflammation in biological samples collected from recurrent airway obstruction (RAO)-affected horses and their controls
… used in human medicine to diagnose and monitor airway disease. The purpose of the study was to determine if similar relationships existed between inflammatory and oxidative stress biomarkers in exhaled breath condensate (EBC), bronchoalveolar lavage fluid (BALF), red blood cells, white blood …

Comparative efficacy of three common treatments for equine recurrent airway obstruction
Objective - evaluate horses with acute airway obstruction using three treatment regimens: tapering doses of dexamethasone (DEX), environmental modification (ENV), and a combination of both treatments (DEX + ENV) by analyzing clinical parameters, pulmonary function testing, bronchoalveolar lavage …

Development and Resolution of Pulmonary Arterial Hypertension in RAO Horses
Equine recurrent airway obstruction (RAO) is associated with airway inflammation and bronchoconstriction in clinically affected horses. Horses demonstrating severe pulmonary compromise develop concurrent secondary pulmonary hypertension. The development of pulmonary hypertension is well documented …

Comparison of Airway Response in Recurrent Airway Obstruction-Affected Horses Fed Steamed Versus Non-steamed Hay
Recurrent Airway Obstruction (RAO)-affected horses experience bronchoconstriction and airway inflammation in response to inhalation of irritants including hay molds. Steaming hay reduces fungal content, but the effect on the antigenic potential has not been investigated. We tested the hypothesis …

Response of Peripheral Blood Lymphocytes from RAO-affected Horses to b2-Agonist Stimulation
Recurrent airway obstruction (RAO) affects middle-age horses, inducing bronchoconstriction and airway inflammation. β2-agonists like salbutamol are used as treatment, promoting airway smooth muscle (ASM) relaxation and bronchodilation. In addition to ASM, inflammatory cells express the …

The Intradermal Skin Test in the Horse: Value as a Diagnostic Modality in Equine Allergies
… antigens in IgE mediated diseases such as equine recurrent airway obstruction (RAO). This study was divided into two experiments. In the first experiment of this study, the hypothesis tested was normal horses would have minimal variability in the wheals formed by intradermal injection of positive …
