Tracheal Endoscopic and Cytological Findings and Blood Examination Results in Thoroughbred Racehorses Suspected to have Lower Respiratory Tract Disease

Cytology of tracheal aspirates, tracheal endoscopic and blood tests were carried out to 86 Thoroughbred racehorses presenting coughs or poor performance which were suspected to have lower respiratory tract disease (LRTD) to assess the conditions of the disorders. Racehorses were classified into coug...

description Cytology of tracheal aspirates, tracheal endoscopic and blood tests were carried out to 86 Thoroughbred racehorses presenting coughs or poor performance which were suspected to have lower respiratory tract disease (LRTD) to assess the conditions of the disorders. Racehorses were classified into coughing (66 horses) and non-coughing (20 horses) groups based on clinical symptoms. Nine Thoroughbred racehorses without respiratory abnormality were used as controls. Assessment of grades of airway mucus, cytology of tracheal aspirates and serum amyloid A (SAA), fibrinogen (Fbg) and pulmonary surfactant protein D (SP-D) measurements were performed. Relationships between age, gender and racing careers were also investigated to understand the characteristics of LRTD in racehorses. Mean age was significantly higher in non-coughing group compared to coughing group. Existence of racing career and number of starts were significantly greater in non-coughing group compared to coughing group. On the other hand, grades of airway mucus were significantly higher in coughing group compared to control group. Percentages of neutrophils in tracheal aspirates were significantly higher in coughing group compared to non-coughing and control groups. SAA, Fbg and SP-D were higher in coughing group compared to non-coughing and control groups indicating that condition of coughing group is in the acute phase. Positive rate of inflammatory airway disease was significantly higher in coughing and non-coughing groups compared to control group. It was concluded that carrying out comprehensive evaluation including investigation on SAA, Fbg and SP-D analysis with airway assessment to Thoroughbred racehorses which were suspected to have LRTD are useful procedure to understand the pathological condition which aid to initiate appropriate treatment, prognosis judgment or to advise trainers to consider altering training regimen.
