Abstract

Rheumatoid arthritis (RA) is a chronic inflammatory disease characterized by invasion of hyperplastic synovial cells and progressive joint destruction. Ozone therapy has been proposed as an immunomodulator and cellular metabolic activator which shows long-term anti-inflammatory effects and serves to reduce further the proinflammatory factors. We purified RA synovial fibroblast cells (RA-SFc) from patients and avoided contaminating macrophages by flow cytometry, then treated them with ozone. Following the observable decreased production of proinflammatory factors TNF-alpha, IL-1beta, and IL-6 from RA-SFc, we infused the cultured RA-SFc into joints of severe combined immunodeficiency mice. The mRNA and protein levels of the RA-SFc exposed to 3% and 5% ozone were the same. As a result, 3% and 5% ozone applied externally ameliorated the inflammatory reaction of RA without toxicity or serious side effects. Therefore, ozone injected into the knees of RA patients could become a valuable treatment, and we confirm the interactive mechanism between ozone and RA-SFc.
