Introduction: Rheumatoid arthritis (RA) is associated with endothelial activation (EA) and dysfunction (ED) as well as vascular inflammation. Recently, local cryotherapy has seen a new interest, showing positive effects on pain and disease activity. This study aimed to determine if local ice cryotherapy may induce positive effects on the systemic vasculature in the rat adjuvant-induced arthritis (AIA) model. Material and methods: AIA was induced by injection of Mycobacterium butyricum in Freund's incomplete adjuvant at the base of the tail in male Lewis rats. Control rats received saline solution. AIA rats were treated or not with ice applied on paws, twice a day from the onset of arthritis for 14 days. Relative mRNA expression of IL-6, TNF-α, CXCL-1, MIP-1α, MCP-1, ICAM-1, VCAM-1 and leukocyte infiltration were measured in thoracic aorta by qRT-PCR and flow cytometry, respectively. Clinical arthritis and joint damage were assessed using an arthritis score and a radiological score, respectively. Results: In AIA rats, a strong aortic infiltration by monocytes, granulocytes, IL-17A-producing CD4+ and CD8+ T cells (Th17 and Tc17), and increased mRNA expression of CXCL-1, TNF-α and IL-6 was measured as compared to controls. Chronic local ice cryotherapy reduced arthritis score (À36%, p < 0.001) and joint damage (À34%, p < 0.05). This effect was associated with a dramatic decrease in CD4+, CD8+ and Tc17 cells infiltration in aorta as compared to untreated AIA. By contrast, ice had no effect on EA markers except VCAM-1 mRNA expression that was significantly increased (p < 0.05). A positive correlation was found between the number of leukocytes, CD4+ and CD8+ T cells in aorta and arthritis score.Discussion/Conclusion: Local ice cryotherapy induced benefits beyond its local articular antiinflammatory effect by drastically reducing vascular inflammation in the systemic vasculature. These findings provide arguments in favor of the use of ice cryotherapy in the therapeutic armamentarium for RA management and its vascular complications.
