Background: Gout is a metabolic disease strictly related to hyperuricemia. The associated intense inflammation and pain are triggered by the deposited monosodium urate crystals (MSU) in joints. The principal therapeutic strategies of gout involve the control of hyperuricemia and antiinflammatory medications.
Objectives: This study aimed to investigate the possible beneficial effects of ozone therapy, a wellknown antioxidant and an immunomodulator, on gouty arthritis and the underlying mechanisms.
Methods: Acute gouty arthritis was induced in male albino rats via MSU crystals intra-articular injection in the ankle joint. The gouty arthritic rats received pre-treatment with ozone, colchicine (as a reference drug), or their combination.
Results: The obtained results of ozone therapy showed an obvious reduction in the degree of edematous ankle swelling, pro-inflammatory cytokines, lipid peroxidation, the nucleotide-binding oligomerization domain-like receptor containing pyrin domain 3 (NLRP3), procaspase-1, caspase-1, interleukin- 1β synovial tissue levels with an enhancement of antioxidant defense system. Additionally, ozone therapy significantly attenuated the histological derangements in gouty arthritic rats.
Conclusion: This study suggests that ozone is able to treat gouty arthritis and reducing synovial injury through an anti-inflammatory effect as well as antioxidant activity.
