Summary
# Editorial Summary: Digital Cryotherapy in Colitis-Associated Laminitis Sepsis-associated laminitis remains a devastating complication of colitis, yet evidence validating common preventive strategies has been limited. This multicentre retrospective analysis examined 130 horses admitted to university hospitals with colitis and systemic inflammatory response between 2002–2012, seeking to identify risk factors for laminitis development and evaluate the efficacy of prophylactic digital cryotherapy (ice therapy). Overall, 21% of horses (27/130) developed clinical laminitis; however, this figure dropped dramatically to just 10% in horses receiving cryotherapy compared with 33% in untreated horses—translating to a tenfold reduction in odds of laminitis development (OR 0.11, 95% CI 0.03–0.44). Beyond cryotherapy, higher admission respiratory rate and blood L-lactate concentration independently predicted laminitis risk, highlighting that affected horses represent a more clinically compromised population, as evidenced by substantially lower survival rates in those developing laminitis (48% versus 98%). These findings provide substantial clinical evidence supporting the routine use of digital cryotherapy as a cost-effective prophylactic intervention during acute colitis management, particularly in cases showing elevated markers of systemic compromise.

Practical Takeaways
- •Implement prophylactic digital cryotherapy in colitis cases as a cost-effective, evidence-based strategy to reduce clinical laminitis incidence by approximately 70%
- •Use systemic inflammatory markers (respiratory rate, blood lactate) to identify high-risk colitis patients who would most benefit from ICE protocols
- •Recognize that laminitis development in colitis cases dramatically worsens prognosis; early intervention with cryotherapy is justified as a preventive measure
Key Findings
- •Laminitis developed in 21% (27/130) of horses with colitis; 10% (7/69) with ICE versus 33% (20/61) without ICE
- •Horses receiving prophylactic digital cryotherapy had 10-fold reduced odds of developing laminitis (OR 0.11, 95% CI 0.03-0.44)
- •Survival to discharge was 48% (13/27) for horses with colitis that developed laminitis versus 98% (101/103) for those without laminitis
- •Higher admission respiratory rate and blood L-lactate were associated with increased laminitis risk alongside lack of ICE treatment
