Gouty arthritis is a rheumatic disease that is characterized by the deposition of monosodium urate (MSU) in synovial joints cause by the increased serum hyperuricemia. This study used a three-dimensional (3D) flowing microfluidic chip to screen the effective candidate against MSU-stimulated human umbilical vein endothelial cell (HUVEC) damage, and found kinsenoside (Kin) to be the leading active component of Anoectochilus roxburghi, one of the Chinese medicinal plant widely used in the treatment of gouty arthritis clinically...

Gout is a progressive, painful, debilitating form of inflammatory arthritis. It is caused by factors that elevate the concentration of serum uric acid (sUA), leading to hyperuricemia (sUA >6.8 mg/dL). Continued elevated sUA can result in monosodium urate (MSU) crystal deposition in joints and soft tissues, and can cause acute and chronic inflammation. The prevalence of hyperuricemia and gout has increased over the last few decades, likely due to an aging population, changes in lifestyles and diet, and an increase in gout-associated comorbidities...

Gout is a common metabolic disease and is characterized by episodic acute and chronic arthritis caused by the deposition of monosodium urate (MSU) crystals in joints and connective tissues. The most commonly involved joint is the first metatarsophalangeal joint. It may also present with nonspecific complaints caused by gouty tophi in unusual sites of the body such as the spine, bone, and middle ear. Such involvements can be disabling and impair the quality of life. In this report, we describe the case of a patient who had complaints of hearing loss and otorrhea...

The recurrence of acute gout attacks remains an unsolved problem in clinical therapy. In order to tackle this problem, poly(ε-caprolactone) (PCL)/gelatin composite fibrous devices loaded with luteolin are presented via electrospinning for the therapy of gout and its recurrence. The luteolin-loaded fibrous device has the capability of inhibiting metabolic activities and reducing inflammation-associated cytokine productions (TNF-a, IL-1β, IL-6) that are secreted by lipopolysaccharide stimulated RAW 264.7 macrophages...

Based on traditional Chinese medicinal theories on gouty arthritis, Zisheng Shenqi decoction (ZSD), a novel Chinese medicinal formula, was developed due to its multiple functions, including reinforcing renal function, promoting blood circulation and relieving pain. In the present study, the effect of ZSD on monosodium urate (MSU) crystal-induced gouty arthritis in rats was investigated and the underlying mechanisms were examined. The data from these investigations showed that the injection of MSU crystals into the ankle joint cavity caused significant elevations in ankle swelling and inflammatory cell infiltration into the synovium, whereas these abnormal changes were markedly suppressed by oral administration of ZSD (40 mg/kg) for 7 days...

Gouty arthritis is a type of monosodium urate (MSU) crystals-induced inflammation in the articular tissue and shows the increased levels of neutrophil infiltration and interleukin-1β (IL-1β) secretion. MSU is capable of activating IL-1β through a nucleotide-binding oligomerization domain-like receptor containing pyrin domain 3 (NLRP3) inflammasome. Epigallocatechin gallate (EGCG), a bioactive polyphenol in green tea with potent antioxidant activity, is effective to prevent rheumatoid arthritis and osteoarthritis...

INTRODUCTION: Gout is considered to be an autoinflammatory disease and the presence of monosodium urate (MSU) crystals stimulates activation of NPRL3 inflammasome and subsequently caspase-1, generating production of active IL-1β and IL-18. However, the association between serum cytokines levels and clinical manifestations of the disease is not yet well understood. We evaluated the serum profile of proinflammatory cytokines (IL-1β, IL-6, IL-8, IL-17A, IL-18, IL-22, and IL-23) and described their relationship with clinical and laboratory data...

OBJECTIVES: Monosodium urate (MSU) crystal deposition in gouty joints promotes the release of inflammatory mediators, in particular interleukin (IL)-1β. The induction of IL-1β production by MSU crystals requires a co-stimulus. The objective of this study was to determine which part of the synovial fluid (SF) provides co-stimulation to MSU crystals to induce IL-1β in macrophages. METHOD: The lipidic fraction (LF) and the protein fraction (PF) were isolated from the SF of patients with arthropathies...

Gout is an inflammatory arthritis characterized by the deposition of monosodium urate crystals (MSU) in the synovial membrane, articular cartilage and periarticular tissues leading to inflammation. Men are more commonly affected, mainly after the 5th decade of life. Its incidence has been growing with the population ageing. In the majority of the cases, the diagnosis is made by clinical criteria and synovial fluid analysis, in search for MSU crystals. Nonetheless, gout may sometimes have atypical presentations, complicating the diagnosis...

Gout is characterized by the monosodium urate monohydrate (MSU)-induced arthritis. Alpha kinase-1 (ALPK1) has shown to be associated with MSU-induced inflammation and gout. Here, we used bioinformatics, proteomics, cell models, and twenty in vitro human assays to clarify some of its role in the inflammatory response to MSU. We found myosin IIA to be a frequent interacting protein partner of ALPK1, binding to its N-terminal and forming a protein complex with calmodulin and F-actin, and that MSU-induced ALPK1 phosphorylated the myosin IIA...

Gout is a common inflammatory arthritis among middle-aged men and postmenopausal women and can be a debilitating disease. Gout results from an elevated body uric acid pool, which leads to deposition of monosodium urate (MSU) crystals, mainly in and around the joints. The MSU crystals trigger release of proinflammatory cytokines, such as interleukin (IL)-1β, IL-6, and tumor necrosis factor (TNF)-α. Ocular manifestations have been uncommonly reported in patients with gout. These include descriptions of tophaceous deposits in different locations of the eye including the eyelids, conjunctiva, cornea, iris, sclera, and orbit...

The present study was undertaken to evaluate the therapeutic effects of Huzhang-Guizhi herb pair (HG), firstly included in Hu-Zhang Power documented in Taiping Shenghui Fang, on monosodium urate (MSU) crystals-induced gouty arthritis in rats. We found that pretreatment with HG in rats with gouty arthritis could significantly attenuate the ankle joint swelling, and this beneficial antigout effect might be mediated, at least in part, by inhibiting tumor necrosis factor-alpha (TNF-α) and interleukin-1 beta (IL-1β) production in synovial fluid as well as nuclear transcription factor-κB p65 (NF-κB p65) protein expression in synovial tissue...

Our previous studies had reported that morin, a bioflavanoid exhibited potent anti-inflammatory effect against adjuvant-induced arthritic rats. In this current study, we investigated the anti-inflammatory mechanism of morin against monosodium urate crystal (MSU)-induced inflammation in RAW 264.7 macrophage cells, an in vitro model for acute gouty arthritis. For comparison purpose, colchicine was used as a reference drug. We have observed that morin (100-300 μM) treatment significantly suppressed the levels of inflammatory cytokines (TNF-α, IL-1β, IL-6, MCP-1 and VEGF), inflammatory mediators (NO and PEG2), and lysosomal enzymes (acid phosphatase, β-galactosidase, N-acetyl glucosamindase and cathepsin D) in MSU-crystals stimulated macrophage cells...

Sanmiao formula (SM) is a compound prescription, which has been used in traditional Chinese medicine since the Ming Dynasty for gouty and rheumatoid arthritis treatments. However, no evidence has been unfolded to show the relationship between SM and gouty arthritis (GA), particularly inhibiting cartilage matrix degradation. In the present study, we undertook a characterization of anti-GA activity of SM using an in vivo rat model induced by potassium oxonate and cold bath together with in vitro studies with chondrocytes for further molecular characterization...

Acute gouty arthritis (AGA) is an auto-inflammatory disease characterized by resolving spontaneously, which suggests that negative feedback loops control inflammatory and immunological responses to monosodium urate (MSU) crystals. By now, the molecular mechanism for spontaneous resolution of acute GA remains unclear; this study was undertaken to evaluate whether IL-37 is involved in spontaneous resolution of AGA. A total of 45 acute GA (AGA),29 non-acute GA (NAGA) male patients and 82 male health control (HC) were involved in this study, we measured IL-7 expression in the peripheral blood mononuclear cells (PBMCs), together with levels of IL-1β, IL-6, IL-10, TNF-α and TGF-β1 in the serum...

Patients with significant gouty arthritis can develop disabling joint pain secondary to monosodium urate (MSU) articular deposition. We report a case of white, chalky MSU crystal deposition covering the articular surfaces of the knee as discovered by total knee arthroplasty. A 65-year-old male with a history of gout presented with bilateral knee pain. His radiographic imaging was negative for gouty tophi, and he elected to undergo left total knee arthroplasty. Intraoperatively a distinct chalky, white paste consistent with MSU deposition was observed covering the articular surfaces of the knee consistent with the diagnosis of gouty arthritis...

INTRODUCTION: The acute gout flare results from a localised self-limiting innate immune response to monosodium urate (MSU) crystals deposited in joints in hyperuricaemic individuals. Activation of the caspase recruitment domain-containing protein 8 (CARD8) NOD-like receptor pyrin-containing 3 (NLRP3) inflammasome by MSU crystals and production of mature interleukin-1β (IL-1β) is central to acute gouty arthritis. However very little is known about genetic control of the innate immune response involved in acute gouty arthritis...
