Abstract

Osteoarthritis (OA) is a chronic and degenerative disease that causes pain, cartilage deformation, and joint inflammation. Lactobacillus species have been used as dietary supplements to induce the production of antimicrobial and anti-inflammatory factors. The goal of this study was to determine whether Lactobacillus acidophilus ameliorates monosodium iodoacetate-induced OA. L. acidophilus showed anti-nociceptive properties and protected against cartilage destruction. It also downregulated the levels of proinflammatory cytokines and increased the levels of anti-inflammatory cytokines in the joints of OA rats. L. acidophilus additionally restored the balance between anabolic and catabolic factors in chondrocytes from OA patients. These results suggest that L. acidophilus can alleviate OA-associated pain and delay the progression of the disease by inhibiting proinflammatory cytokine production and reducing cartilage damage.
