Background.Urate crystals-induced inflammation is a critical factor during the initiation of gouty arthritis. Berberine is well known for its anti-inflammatory activity. However, the underlying effects of berberine on monosodium urate crystals-induced inflammation remain obscure.Objectives.This study is set to explore the protective effect and mechanism of berberine on monosodium urate crystals-induced inflammation in human monocytic THP-1 cells.Methods.The mRNA levels of NLRP3 and IL-1βwere measured by Real-Time PCR, and the protein levels of NLRP3 and IL-1βwere determined by ELISA, Western blot, and immunofluorescence.Results.The NLRP3 and IL-1βexpressions were significantly increased in model group compared to that in normal group (P<0.05). Meanwhile, there was significant reduction in the expressions of NLRP3 and IL-1βmRNA in groups 6.25 μM berberine and 25 μM berberine when compared with model group (P<0.05).Conclusions.Therefore, berberine alleviates monosodium urate crystals-induced inflammation by downregulating NLRP3 and IL-1βexpressions. The regulatory effects of berberine may be related to the inactivation of NLRP3 inflammasome.

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.

How macrophages are programmed to respond to monosodium urate crystals (MSUc) is incompletely understood partly due to the use of a toll-like receptor-induced priming step. Here, using genome wide transcriptomic analysis and biochemical assays we demonstrate that MSUc alone induces an in vitro metabolic and inflammatory transcriptional program in both human and murine macrophages markedly distinct from that induced by LPS. Genes uniquely up-regulated in response to MSUc belonged to lipids, glycolysis, and transport of small molecules via SLC transporters pathways. Sera from individuals and mice with acute gouty arthritis provided further evidence for this metabolic rewiring. This distinct macrophage activation may explain the initiating mechanisms in acute gout flares and is regulated through JUN binding to the promoter of target genes through activation of JNK (but not by P38) in a process that is independent of inflammasome activation. Finally, pharmacological JNK inhibition limited MSUc-induced inflammation in animal models of acute gouty inflammation.

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.

Vatarakta is more distressing and common metabolic disorder prevalent in present era. It is Vatapradhana Tridoshaja Vatavyadhi where Rakta is main Dushya. Vata is a predominant Dosha in Vatarakta, when it is excessively aggravated with vitiated Rakta is called Vatarakta. Vatarakta is correlated with gout in modern science. Gout is an abnormality of purine metabolism causes hyperuricemia and deposition of monosodium urate crystals in joints. Pain is predominant symptom of gout, which disturbs day-today life of the patients. The Panchakarma is not only a important component of Ayurvedic treatment but it is also forms the fundamental basis of Ayurveda therapy. The different procedures like Swedana, Vamana, Virechana, Basti, Sirovirechana, Raktamokshana focus on the purification which detoxifies the human body, i.e. the correction of the metabolism at molecular level. These detoxification procedures are essential components of the management in various metabolic disorders. So Panchakarma is an unique approach in the management of Vatarakta.
