Revisiting predictive biomarkers of musculoskeletal injury in thoroughbred racehorses: longitudinal study in polish population.

Abstract: High prevalence of musculoskeletal disorders in racehorses and its impact on horse welfare and racing economics call for improved measures of injury diagnosis and prevention. Serum biomarkers of bone and cartilage metabolism have previously shown promise in prediction of musculoskeletal injuries in horses. This study aimed to re-evaluate usability of the predictive serum biomarkers identified in North American Thoroughbred racehorses in a geographically distinct group of Polish Thoroughbreds. Results: Serum concentrations of bone and cartilage biomarkers: osteocalcin, c-terminal telopeptide of type I collagen, total glycosaminoglycans (GAG), chondroitin sulfate epitope and c-propeptide of type II procollagen (CPII) were evaluated in the beginning and the next 3 months of one racing season in a cohort of twenty-six 2-year-old Polish racehorses. Exit criteria were diagnosis of musculoskeletal injury, leading to > 5 days off training (n = 8), or completion of 3 study months with no training interruptions (n = 18). Normalized results and matching archival data from 35 2-year-old North American racehorses was used for logistic regression analysis to identify universal predictors of injury. Mean GAG and CPII levels were lower in injured group comparing to control, which is consistent with previous findings in racehorses. These biomarkers were also identified as predictors of injury in the mixed population model. Population origin had no significant effect on predictive value of evaluated biomarkers (Wald test p = 0.137). Decreased osteocalcin and increased c-terminal telopeptide of type I collagen levels in injured horses comparing to controls were specific for Polish population and signalized disruption in bone turnover homeostasis. Conclusions: Changes in serum GAG and CPII in racehorses at risk of injury appear to be similar across distinct populations while dynamics of serum bone marker is more population-specific.

This research study investigates the usefulness of previously identified serum biomarkers in predicting musculoskeletal injuries in racehorses, using a population of Polish Thoroughbreds in comparison with data from North American Thoroughbreds.

Objective of the Research

  • The study aims to reassess the effectiveness of certain serum biomarkers, which were previously identified in North American Thoroughbreds, in predicting musculoskeletal injuries in a geographically distinct group of Polish Thoroughbreds.

Methodology Employed

  • Twenty-six 2-year-old Polish racehorses were observed over the course of one racing season. Serum concentrations of certain bone and cartilage biomarkers – including osteocalcin, c-terminal telopeptide of type I collagen, total glycosaminoglycans (GAG), chondroitin sulfate epitope, and c-propeptide of type II procollagen (CPII) – were evaluated at the start and over the next three months.
  • Exit criteria included diagnosis of a musculoskeletal injury that resulted in more than five days off training (eight horses fit this criteria), or completion of three study months without any training interruptions (eighteen horses fit this criteria).
  • The data derived from this were then normalized and assessed alongside archival data from 35 2-year-old North American racehorses, and logistic regression analysis was used to detect universally applicable predictors of injury.

Key Findings

  • The injured group of horses displayed lower mean GAG and CPII levels in comparison to the control group; a result consistent with previous findings on racehorse injuries.
  • The study identified these biomarkers as predictors of injury within the mixed population model, and found that the geographical origin of the horses did not appear to significantly affect the predictive value of these biomarkers.
  • Decreased osteocalcin and increased c-terminal telopeptide of type I collagen levels in injured horses – changes indicative of disrupted bone turnover homeostasis – were found to be specific to the Polish population.

Conclusions

  • The study concludes that changes in serum GAG and CPII levels among racehorses at risk of injury seem to be similar across different populations, whereas the dynamics of serum bone markers are more population-specific.
