Associations of horse age, joint type, and osteochondral injury with serum and synovial fluid concentrations of type II collagen biomarkers in Thoroughbreds.
Abstract: To determine the effects of horse age, osteochondral injury, and joint type on a synthesis biomarker and 3 degradative biomarkers of type II collagen in Thoroughbreds. Methods: Healthy rested adult (3- to 12-year-old) Thoroughbreds (n = 19), yearling (1- to 2-year-old) Thoroughbreds (40), and Thoroughbred racehorses (2 to 7 years old) undergoing arthroscopic surgery for removal of osteochondral fragments that resulted from training or racing (41). Methods: Samples of blood and metacarpophalangeal, metatarsophalangeal, or carpal joint synovial fluid (SF) were collected from all horses. Commercially available assays were used to analyze SF and serum concentrations of type II collagen biomarkers of synthesis (carboxy propeptide of type II collagen [CPII]) and degradation (cross-linked C-telopeptide fragments of type II collagen [CTX II], neoepitope generated by collagenase cleavage of type I and II collagen [C1,2C], and neoepitope generated by collagenase cleavage of type II collagen [C2C]). Results: Osteochondral injury affected concentrations of CPII, CTX II, C1,2C, and C2C in SF, serum, or both, compared with concentrations in healthy adult horses. Compared with adult horses, yearling horses had increased SF or serum concentrations of degradative biomarkers (CTX II, C1,2C, and C2C). Concentrations were higher in carpal than metacarpophalangeal or metatarsophalangeal joints for all biomarkers in osteochondral-injured horses. Variable differences in SF concentrations between joint types were detected in healthy adult and yearling horses. Conclusions: Horse age, osteochondral injury, and joint type all significantly affected type II collagen biomarker concentrations in SF and serum of Thoroughbreds.

Summary

The study investigates the effects of age, osteochondral injury, and joint type on type II collagen biomarkers in Thoroughbred racehorses. The research revealed significant variations of these biomarkers in blood and synovial fluid across different age groups, injuries and joint types.
Research Methodology
- The study involved three categories of Thoroughbred horses: healthy adults (3-12 years old, 19 horses), yearlings (1-2 years old, 40 horses), and those undergoing arthroscopic surgery for osteochondral fragment removal due to training or racing injuries (2-7 years old, 41 horses).
- Blood and synovial fluid samples were taken from all horses, focusing on the metacarpophalangeal, metatarsophalangeal, or carpal joints.
- The samples were analyzed using commercial assays to measure concentrations of type II collagen biomarkers. These included a synthesis biomarker, carboxy propeptide of type II collagen (CPII), and three degradative biomarkers: cross-linked C-telopeptide fragments of type II collagen (CTX II), neoepitopes created by collagenase cleavage of type I and II collagen (C1,2C), and neoepitopes created by collagenase cleavage of type II collagen (C2C).
Research Findings
- In horses with osteochondral injury, concentrations of all the biomarkers (CPII, CTX II, C1,2C, C2C) were affected in either the synovial fluid, the serum, or both, in comparison with healthy adult horses.
- Yearling horses had higher concentrations of degradative biomarkers (CTX II, C1,2C, and C2C) in synovial fluid or serum compared to adult horses.
- Injured horses had higher concentrations of all biomarkers in carpal joints compared to metacarpophalangeal or metatarsophalangeal joints.
- The type of joint impacted the concentrations of these biomarkers in synovial fluid with variable differences detected in healthy adult and yearling Thoroughbreds.
Conclusion
The researchers concluded that age, osteochondral injury, and joint type significantly affect the concentration of biomarkers related to type II collagen synthesis and degradation in Thoroughbred horses. This information may prove useful for veterinarians and those in the equine industry for the monitoring and management of joint health in horses.
