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.

MicroRNAs (miRNAs) are a class of noncoding RNAs that mainly negatively regulate gene expression. miRNAs have important roles in many diseases, including inflammatory diseases. Gout is a common arthritis caused by deposition of monosodium urate crystals within joints. Recent studies suggested that miRNAs may be involved in the development of inflammatory arthritis, including acute gouty arthritis. In the present review, we systemically discuss relevant publications in order to provide a better understanding on the possible role of miRNAs in gout. miRNAs may act as regulators of gout pathogenesis via several pathways. Targeting miRNAs may be a promisingstrategy in the treatment of gout.

We present an elderly diabetic man with left hallux pain and drainage who was initially diagnosed with acute gouty arthritis using the diagnostic rule for acute gout and monosodium urate crystals presented on synovial fluid analysis. Further investigation with surgical debridement, plain X-ray, MRI and wound culture revealed concomitant Citrobacter koseri septic arthritis with osteomyelitis. C. koseri is considered an opportunistic infection that rarely causes musculoskeletal infections. Acute gouty arthritis and septic arthritis are rarely seen occurring concomitantly in the same joint and are often difficult to differentiate due to similar findings on exam and imaging. The present case illustrates that osteomyelitis with an opportunistic organism can present concomitantly with acute gouty arthritis, and the diagnosis of one should not exclude the other.

Acute gouty arthritis represents an inflammatory response to microcrystals of monosodium urate that precipitate in joint tissues from supersaturated body fluids or are shed from preexisting articular deposits [1]. Gout is a metabolic disease characterized by recurrent episodes of arthritis associated with the presence of monosodium urate crystals in the tissue or synovial fluid during the attack.These forms of crystal-induced arthritis usually affect peripheral joints, including knee, ankle, wrist, and metacarpophalangeal and metatarsophalangeal joints. All of them may be associated with other inflammatory, endocrine diseases [2]. The present study was done to highlight the relationship between increased levels of uric acid and specific laboratory tests in order to possible forecast development of further disease in patients with gouty arthrithis.The present study was done on 34 patients hospitalized in Felix Hospital of Rehabilitation in 2015-2016, with age between 44 and 74, having the main diagnosis of gouty arthritis.We studied the following laboratory tests:urea and other related analysis, like uric acid, creatinine, cholesterol, glutamate pyruvate transaminase and glutamate oxalate transaminase.

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.

Abstract: Hyperuricemia, a highly prevalent condition in adult population, is associated with hemodynamic and metabolic disturbances. Albeit, pathophysiological aspects of hyperuricemia are still not clearly understood. Uric acid plays an essential role in immunity by induction of some cytokines and chemokines, such as TNFα, Il-1β, IL-6, CXCL8 (IL-8), and CXCL1 (growth-related oncogene α). Deposits of monosodium urate crystals in joint cavities and periarticular tissues  are related to an autoinflammatory disturbance, namely gout. Keywords: hyperuricemia, monosodium urate crystal, immune responsse.   Abstrak: Hiperurisemia merupakan suatu keadaan yang umum dijumpai pada populasi dewasa dan berhubungan dengan kelainan metabolik dan hemodinamik. Aspek patofisiologik dari hiperurisemia belum sepenuhnya dipahami dengan jelas. Asam urat berperan penting dalam imunitas dengan menginduksi berbagai sitokin dan kemokin, antara lain TNFα, Il-1β, IL-6, CXCL8 (IL-8) dan CXCL1 (growth-related oncogene α). Deposit kristal monosodium urat di dalam rongga sendi dan jaringan periartikuler berkaitan dengan gangguan autoinflamasi yang dikenal sebagai gout. Kata kunci: hiperurisemia, kristal monosodium urat, respons imun.

Objective Acute gout is a painful, inflammatory arthritis that features a rapidly escalating inflammatory response resulting from the formation of monosodium urate crystals in the affected joint space. Previously, we found that Chuanhu anti-gout mixture (CAGM) had similar effects as colchicine against gout in the clinic. Subsequently, to improve its effectiveness and efficacy, we modified the original formulation of CAGM. The current study evaluated the effectiveness of the modified formulation in mice. Methods Potassium oxonate (PO) was used to establish a mouse model of hyperuricemia. Plasma levels of uric acid and creatine were determined using the respective test kits. Hepatic xanthine oxidase (XOD) expression was examined by enzyme-linked immunosorbent assay. To explore the underlying mechanism, renal urate transporter 1 (URAT1) mRNA levels were evaluated by quantitative real-time PCR. Allopurinol and benzbromarone were used as reference drugs. Results The original CAGM and its modified high-dose formulation significantly reduced serum uric acid and creatine levels in hyperuricemic mice. In addition, the CAGM-treated groups displayed lower mRNA levels of hepatic XOD and renal URAT1. Conclusions CAGM and its modified formulation significantly ameliorated PO-induced hyperuricemia in mice, which might be partially attributable to reductions of hepatic XOD and renal URAT1 levels.

Abstract Background Gout is initiated by the precipitation of monosodium urate (MSU) crystals within the joints and soft tissues, and it can eventually cause acute or chronic arthritis. MSU crystals trigger, amplify, and maintain a strong inflammatory response through promoting proinflammatory activity. In this study, the therapeutic effects of Stephania hainanensis (S. hainanensis) total alkaloid (SHA) were tested and evaluated on MSU-induced acute gouty arthritis in a mouse model. Methods After oral administration of SHA (10 or 20 mg/kg) or the antigout medicine colchicine (0.5 mg/kg) once daily for 3 consecutive days, MSU crystals suspended in saline (2.5 mg/50 μl) were intradermally injected into the right paw of the mice. Then, SHA and colchicine were administered for another 2 days. During this period, swelling of the ankle and clinical scores were measured at 12, 24, and 48 h postinjection. After the mice were euthanized, inflammatory cytokine expression and paw tissue inflammation-related gene and protein expression, and a histopathological analysis was performed. Results SHA had obvious therapeutic effects on MSU-induced acute gouty arthritis in mice. SHA alleviated ankle swelling and inhibited the production of cytokines, such as IL-1β and TNF-α. In addition, NLRP3, Caspase-1 and IL-1β, which are activated by MSU were also suppressed by SHA. The histological evaluation showed that SHA relieved the infiltration of inflammation around the ankle. Conclusions These results suggest that SHA is capable of anti-inflammatory activities and may be useful for treating gouty arthritis.
