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 …

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 …

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 …

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 …

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 …

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 …

Importanza prognostica delle citochine e loro ruolo nell'immunomodulazione: risultati di studi sperimentali in vivo e in vitro
… understanding in the pathogenesis during horse Recurrent Airway Obstruction, foal sepsis, Bovine Viral Diarrhea Virus infection and dog Parvovirus infection and the effects of these agents on the host immune system. As experimentations with mice have shown, some pathologies of the respiratory …

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 …

The Comparison of Airway Responses of Normal Horses Fed Round Bale versus Square Bale Hay
… round bale hay (RBH) has been associated with airway inflammation. The purpose of this study was to determine if horses fed RBH for a 6-week period demonstrated more evidence of airway inflammation than horses fed square bale hay (SBH) of comparable quality. Hypothesis - The respiratory health …
