AbstractThe purpose of this study was to investigate potential anti-gouty effect of astilbin (AS) and its possible mechanisms. In mice with hyperuricemia induced by potassium oxonate (OXO) and yeast extract powder (YEP), AS and febuxostat (FB) reduced the serum uric acid (UA) and xanthine oxidase (XO). Moreover, AS and FB reduced the levels of reactive oxygen species and increased the content of superoxide dismutase (SOD), glutathione peroxidase and catalase present in the serum. In acute gouty arthritis rats induced by intraarticular monosodium urate crystal injection, AS and Colchicine (COL) alleviated the ankle joints swelling, and reduced the inflammatory cell infiltration. AS also reduced the levels of interleukin 1β, interleukin 6, tumor necrosis factor alpha and monocyte chemoattractant protein 1 in liver. The present study first confirmed the anti-gouty effect of AS in mice with hyperuricemia and rats with acute gouty arthritis, which provides the experimental evidence for further evaluation of AS as a candidate for gout treatment.

Set Up

Rhizoma Dioscoreae Nipponicae (RDN) is an herbal medicine. In the theories of Traditional Chinese Medicine (TCM), the function of RDN is to expel wind and remove dampness. Inflammatory mechanisms play an important role in the pathological process and prognosis of acute gouty arthritis (AGA). The aim of this study was to determine the specially expressed proteins through testing the proteins of the synovium in rats with AGA. The animal model of AGA was set up by Monosodium urate crystal (MSU) combined with hypoxanthine (HX), which was ameliorated in our previous experiment. Blood samples for measurement of serum uric acid were collected prior to sacrifice. Outcomes were assessed (two days after injection) by histological stain and protein quantitation. Three chips of RayBioⓇHuman Label-based Antibody Array I were applied to detect 90 proteins in the synovium tissue of AGA rats. 14 differently expressed proteins were found in the synovium of AGA rats, and nine of them were first found in this model. There were seven up-regulated and seven down-regulated proteins, both TRAIL and Neuropilin-2 could be identified as key contributors to the pathomechanism of AGA.

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 anti-inflammatory medications. Objectives: This study aimed to investigate the possible beneficial effects of ozone therapy, a well-known antioxidant, and an immunomodulation, 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 combination. Results : The obtained results of ozone therapy showed obvious reduction in the degree of ankle edematous 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 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.

The destructive potential of intracellular crystals has been recognized for over a century. The mechanisms by which crystals induce inflammation and bone and cartilage destruction have been elucidated over the past decade. The three most common crystal-induced arthropathies are caused by precipitation of monosodium urate monohydrate, calcium pyrophosphate dihydrate (CPP) and basic calcium phosphate. The definition, epidemiology, pathogenesis and etiology, diagnosis, and treatment of gout and CPP crystal deposition are reviewed, as well as the clinical stages of gout (i.e., acute gouty arthritis, intercritical gout, advanced gout, nonclassic presentations of gout, and other conditions associated with gout). Also reviewed are the clinical manifestations of calcium pyrophosphate dihydrate deposition disease (CPPD), such as asymptomatic CPPD, osteoarthritis with CPPD, acute CPP crystal arthritis, and chronic CPP crystal inflammatory arthritis. Figures illustrate renal transport of urate, monosodium urate crystals, acute gouty flare, advanced gouty arthritis, gouty synovial fluid, radiographic changes of advanced gout, ultrasound appearance of the femoral intercondylar cartilage, pharmacologic management of gout, the effect of gender and age on knee chondrocalcinosis, radiographs of chondrocalcinosis, and compensated polarized microscopy of CPPD. Tables present the major factors responsible for hyperuricemia, characteristics of classic gouty flares, antiinflammatory therapy for gout, and urate-lowering therapy. This chapter contains 90 references. This review contains 11 figures, 12 tables, and 88 references.

Acute gout is a common inflammatory arthritis in the adult population. Epidemiological evidence suggests that the prevalence of gout is steadily on the rise due to longevity, coexisting comorbidities, and iatrogenic causes contributing to hyperuricaemia. Acute gout usually presents as a self-limiting flare of synovitis that occurs due to deposition of monosodium urate crystals. The frequency of flares generally increases over time in patients who continue to have hyperuricaemia and their risk factors for acute gout attacks have not been adequately addressed. Effective treatment of acute gouty arthritis is primary focused on pain which is the primary symptom but must target both the pain and underlying inflammation. Acute gout is frequently treated with non-steroidal anti-inflammatory agents, colchicine, and corticosteroids. This chapter reviews the available therapies for management of acute gout and ones that have shown promising results.

Gouty arthritis is an inflammatory joint disease closely related to hyperuricemia. It is characterized by deposition of monosodium urate crystals in the joints, resulting in an intense inflammatory process and pain. Control of hyperuricemia and anti-inflammation treatments are the main therapeutic approaches. However, the commonly used drugs for inhibiting uric acid and acute gouty arthritis have obvious gastrointestinal and renal toxicity; thus, there is an urgency to develop new alternative therapeutic drugs. An extract of Tu-Teng-Cao (TTC), a compound drug used in traditional Chinese medicine, has been widely applied to the clinical treatment of arthritis. In this study, we investigated the therapeutic effects of TTC on gouty arthritis. In this study, an animal model of acute gouty arthritis with hyperuricemia was established using potassium oxonate and monosodium urate crystals. After treatment with TTC, the results showed obvious therapeutic effects on the rat model of acute gouty arthritis. The treatment significantly attenuated the degree of ankle swelling, inflammation, and dysfunction index, and the levels of proinflammatory cytokines. In addition, TTC has significant antihyperuricemia activity in rats with hyperuricemia induced by potassium oxonate. Histological evaluation showed that TTC relieved pathological damage in rats with acute gouty arthritis induced by monosodium urate crystals. All the groups treated with TTC showed improvement in cartilage degeneration, cell degeneration, synovial hyperplasia, and inflammatory cell invasion in the ankle joint of rats. TTC significantly alleviated swelling, inflammation, and bleeding of the renal corpuscle and convoluted tubules of rats. The results of this study suggest that TTC is capable of treating gouty arthritis and decreasing ankle injury through the control of uric acid and inflammation.
