The Combination of Probiotic Complex, Rosavin, and Zinc Improves Pain and Cartilage Destruction in an Osteoarthritis Rat Model.

Osteoarthritis (OA), a degenerative disorder, induces pain, joint inflammation, and destruction of the articular cartilage matrix. Probiotic complex, rosavin, and zinc have been used as dietary supplements that exhibit anti-inflammatory and antioxidant properties. However, there is no evidence demonstrating a synergic effect in OA. This study aims to determine whether combination with probiotic complex, rosavin, and zinc decreases progression of monosodium iodoacetate (MIA)-induced OA rat model. The combination improved pain levels by preventing cartilage damage. The expression of proinflammatory cytokines and catabolic factors was reduced by the combination within the joint tissue. However, the combination increased anti-inflammatory cytokines as well as the anabolic factor production. The gene level of catabolic factors was decreased with treatment of the combination in chondrocytes isolated from OA patients. These results suggest that the combination can improve MIA development through the inhibition of proinflammatory cytokines and cartilage destruction, thus playing a key role as a therapeutic candidate for OA treatment.
