[Acute non-traumatic single-articular pain]. / Douleur monoarticulaire aiguë non traumatique.

The main non-traumatic causes of acute single-joint pain are microcrystalline, degenerative, reactive and septic arthritis. Septic arthritis must be excluded quickly with puncture of the joint effusion. In the absence of sepsis, surgical drainage can be performed within 24 hours after admission to the emergency unit. Concerning gout, recommendations advise the use of imaging for diagnosis in case of joint puncture not feasible and the introduction of urate-lowering treatment during the acute attack. Regarding reactive arthritis, the presence of microbial elements in the affected joints improves the understanding of its pathophysiology. Finally, osteoarthritis guidelines emphasize the importance of self-management programs for painful crises.

Les principales causes non traumatiques de la douleur monoarticulaire aiguë sont les arthrites microcristallines, dégénératives, réactives et septiques. Cette dernière doit être exclue rapidement avec une ponction de l'épanchement articulaire. En l'absence de sepsis, un drainage chirurgical peut être réalisé dans un délai de 24 heures après l'admission aux urgences. Concernant la goutte, les recommandations conseillent l'utilisation de l'imagerie pour la pose du diagnostic en cas de ponction articulaire non réalisable et l'introduction d'un traitement hypo-uricémiant pendant la crise aiguë. À propos de l'arthrite réactive, la présence d'éléments microbiens dans les articulations touchées améliore la compréhension de sa physiopathologie. Enfin, pour la prise en charge de l'arthrose, les guidelines soulignent l'importance de programmes d'autogestion des crises douloureuses.

Exercise and hyperuricemia: an opinion article.

Hyperuricaemia (HUA) is an abnormally high concentration of serum urate caused by either an excess of uric acid production or decreased excretion capacity in the body. Serum urate concentration forms sodium salts that deposit in the soft tissues of the joints, ultimately leading to gout. Additionally, HUA is strongly associated with several acute and chronic illnesses. In various clinical guidelines and practices, xanthine oxidase inhibitors, such as allopurinol and febuxostat, are commonly used as the initial medication for treating HUA. However, extended usage of urate-lowering drugs may have risks, including cardiovascular thrombotic events and hepatic impairment. Implementing a scientifically informed fitness diet in conjunction with appropriate exercise may decrease HUA. Unfortunately, there is currently a shortfall in exercise intervention trials for individuals suffering from HUA. Most of the previous evidence suggesting that exercise improves serum urate levels comes from intervention trials in other populations, and serum urate is only one of the outcomes observed. This opinion article analyses the causes of HUA, offers dietary and exercise guidance with the aim of furnishing a point of reference for individuals with HUA or fitness enthusiasts.

Gout: A Rapid Review of Presentation, Diagnosis and Management.

Gout is inflammatory arthritis caused by monosodium urate crystal deposition in articular and non-articular structures. Acute gout flares are often monoarticular/polyarticular involving lower extremity joints characteristically involving 1st metatarsophalangeal joint. However, gout flares can also be polyarticular, involving upper extremity joints, especially in patients with multiple comorbidities and contraindications to urate-lowering therapies (ULT). Risk factors exacerbating gout flares include obesity, high alcohol and purine-rich food consumption, and the use of diuretics. Diagnosis requires synovial fluid analysis with direct visualization of monosodium urate crystals. Acute flares are managed with steroids, non-steroidal anti-inflammatory drugs, or colchicine. Long-term management includes lifestyle modifications including a heavy emphasis on weight loss, avoidance of alcohol, purine-rich foods, and diuretics. ULT is indicated in patients with 2 or more gout flares/year, tophi, or radiographic evidence of gouty arthropathy. Although allopurinol is the first-line ULT agent, it does carry a risk of inducing severe cutaneous adverse reactions, especially in patients with chronic kidney disease and patients harboring the HLA-B*5801 allele. Other ULT agents include febuxostat and probenecid. ULT is usually titrated to achieve goal serum uric acid (SUA) levels below 6 mg/dL. However, in patients with tophi, a lower SUA target of less than 5 mg/dL should be implemented for prompt urate crystal dissolution.

High vegetable consumption and regular exercise are associated with better quality of life in patients with gout.

BACKGROUND/AIMS: The Gout Impact Scale (GIS), a part of the Gout Assessment Questionnaire 2.0, is used to measure gout-specific health-related quality of life (HRQOL). Although several studies have been conducted on the factors affecting the HRQOL of patients with gout, few have focused on lifestyle factors. This study aimed to investigate the correlation between lifestyle habits and HRQOL using the GIS in patients with gout. METHODS: We used data from the Urate-Lowering TheRApy in Gout (ULTRA) registry, a prospective cohort of Korean patients with gout treated at multiple centers nationwide. The patients were aged ≥18 years and met the 2015 American College of Rheumatology/European League Against Rheumatism gout classification criteria. They were asked to complete a GIS and questions regarding their lifestyle habits at enrollment. RESULTS: The study included 232 patients. 'Gout concern overall' scores in the GIS were significantly lower in patients who exercised more frequently and consumed soft drinks and meat less, and 'well-being during attack' scores were significantly lower in patients who consumed vegetables and exercised more frequently. The frequency of vegetable consumption had a negative linear relationship with the 'well-being during attack' and 'gout concern during attack' scores (p = 0.01, p = 0.001, respectively). The frequency of exercise had a negative linear relationship with the 'gout concern overall' and 'gout concern during attack' scores (p = 0.04 and p = 0.002, respectively). CONCLUSION: Patients with gout who frequently consumed vegetables and exercised regularly experienced less impact of gout, exhibiting a better GIS that represented HRQOL.

The effect of exercise rehabilitation with exergames combined with ice therapy in the treatment of obese patients with gout: protocol for a clinical trial.

BACKGROUND: Gout remains a leading cause of inflammatory arthritis worldwide, and the main risk factor for gout is persistent hyperuricemia. The clinical management of gout is mostly drug-based, and other treatment options are often ignored. This research proposal will explore whether exergames combined with ice therapy can help patients with gout to lose weight, relieve pain, improve the range of movement, improve quality of life, decrease uric acid level, decrease kinesiophobia and improve mental health of patients with gout. METHODS: This experiment will use a two-arm randomized controlled design. The study setting is at the Advanced Medical and Dental Institute (AMDI), Universiti Sains Malaysia (USM). Obese patients with gout (N = 30) will be randomly assigned to the control group (receive an exergames intervention) and intervention group (receive an exergames intervention combined with ice therapy). The outcomes measurement will be conducted before (baseline) and after intervention (4 weeks). Then, it will be followed up at 12 weeks. DISCUSSION: To our knowledge, no study has investigated the effect of exergames and ice therapy among gout patients. This study is expected to demonstrate that exercise rehabilitation facilitated by exergames with ice therapy is more effective in gout management compared to a conventional rehabilitation intervention.

Mild hyperthermia enhanced synergistic uric acid degradation and multiple ROS elimination for an effective acute gout therapy.

BACKGROUND: Acute gouty is caused by the excessive accumulation of Monosodium Urate (MSU) crystals within various parts of the body, which leads to a deterioration of the local microenvironment. This degradation is marked by elevated levels of uric acid (UA), increased reactive oxygen species (ROS) production, hypoxic conditions, an upsurge in pro-inflammatory mediators, and mitochondrial dysfunction. RESULTS: In this study, we developed a multifunctional nanoparticle of polydopamine-platinum (PDA@Pt) to combat acute gout by leveraging mild hyperthermia to synergistically enhance UA degradation and anti-inflammatory effect. Herein, PDA acts as a foundational template that facilitates the growth of a Pt shell on the surface of its nanospheres, leading to the formation of the PDA@Pt nanomedicine. Within this therapeutic agent, the Pt nanoparticle catalyzes the decomposition of UA and actively breaks down endogenous hydrogen peroxide (H2O2) to produce O2, which helps to alleviate hypoxic conditions. Concurrently, the PDA component possesses exceptional capacity for ROS scavenging. Most significantly, Both PDA and Pt shell exhibit absorption in the Near-Infrared-II (NIR-II) region, which not only endow PDA@Pt with superior photothermal conversion efficiency for effective photothermal therapy (PTT) but also substantially enhances the nanomedicine's capacity for UA degradation, O2 production and ROS scavenging enzymatic activities. This photothermally-enhanced approach effectively facilitates the repair of mitochondrial damage and downregulates the NF-κB signaling pathway to inhibit the expression of pro-inflammatory cytokines. CONCLUSIONS: The multifunctional nanomedicine PDA@Pt exhibits exceptional efficacy in UA reduction and anti-inflammatory effects, presenting a promising potential therapeutic strategy for the management of acute gout.

The Impact of mHealth-Based Continuous Care on Disease Knowledge, Treatment Compliance, and Serum Uric Acid Levels in Chinese Patients With Gout: Randomized Controlled Trial.

Background: In patients with gout, suboptimal management refers to a lack of disease knowledge, low treatment compliance, and inadequate control of serum uric acid (SUA) levels. Several studies have shown that continuous care is recommended for disease management in patients with gout. However, in China, the continuous care model commonly used for patients with gout requires significant labor and time costs, and its efficiency and coverage remain low. Mobile health (mHealth) may be able to address these issues. Objective: This study aimed to explore the impact of mHealth-based continuous care on improving gout knowledge and treatment compliance and reducing SUA levels. Methods: This study was a single-center, single-blind, and parallel-group randomized controlled trial. Participants were recruited at the West China Hospital of Sichuan University in Chengdu, China, between February 2021 and July 2021 and were randomly assigned to the intervention and control groups. The intervention group received continuous care via an mHealth app, which includes modules for health records, 24 weeks of gout-related health education materials, and interactive support. The control group received routine continuous care, including face-to-face health education, paper-based health education materials consistent with the content for the intervention group, and telephone consultations initiated by the patient. Follow-up was conducted at 6 months. Participants' gout knowledge levels and treatment compliance were measured at baseline and the 12th and 24th weeks, and participants' SUA levels were measured at baseline and the 24th week. The intention-to-treat principle and a generalized estimating equation model were used to test the effect of the intervention. Results: Overall, 258 potential participants underwent eligibility assessments, and 120 were recruited and randomized into the intervention (n=60, 50%) and control (n=60, 50%) groups. Of the 120 participants, 93 (77.5%) completed the 24-week study. The 2 groups had no significant differences in sociodemographic or clinical characteristics, and the baseline measurements were comparable (all P>.05). Compared with the control group, the intervention group exhibited a significant improvement in gout knowledge levels over time (ß=0.617, 95% CI 0.104-1.129; P=.02 and ß=1.300, 95% CI 0.669-1.931; P<.001 at the 12th and 24th weeks, respectively). There was no significant difference in treatment adherence between the 2 groups at the 12th week (ß=1.667, 95% CI -3.283 to 6.617; P=.51), while a statistical difference was observed at the 24th week (ß=6.287, 95% CI 1.357-11.216; P=.01). At the 24th week, SUA levels in both the intervention and control groups were below baseline, but there was no significant difference in SUA changes between the 2 groups (P=.43). Conclusions: Continuous care based on the mHealth app improved knowledge levels and treatment compliance among patients with gout. We suggest incorporating this intervention modality into standard continuous care for patients with gout.

Gout and its management.

Gout is a common and treatable chronic disease of monosodium urate crystal deposition. It is experienced as extremely painful episodes of joint inflammation that impact all aspects of the person's life. This Clinical Perspectives article provides an update on gout diagnosis, medications and strategies to improve the quality of gout care.

[Gout, beyond the joint: How should we treat it?] / La gota, más allá de la articulación: ¿cómo debemos tratarla?

Gout is a disease caused by the chronic deposition of monosodium urate crystals. Its clinical presentation as an acute, self-limiting arthritis and the belief that it is a banal, self-inflicted disease have led to its poor management. Despite advances in the knowledge of the disease and the simplicity of its management, no more than 30% of patients are well treated. In Spain, the prevalence of gout is 2.5% and its incidence is increasing. In the following article we will review the pathogenesis of gout and hyperuricaemia, highlighting the greater weight of genetics and renal function over diet. We will look at the consequences of crystal deposition. Gout, in addition to its joint presentation and renal involvement, has been shown to be an independent cardiovascular risk factor. Hypouricemic therapy is the most important treatment, as it is the one that dissolves the crystals and cures the disease. This requires the sustained achievement of uricemia levels below 6mg/dl. We will also review preventive and flares treatment, as well as the role of patient education in terms of both lifestyle and dietary habits and adherence to pharmacological treatment.

Gout in Native Hawaiian Patients in Hawai'i: Clinical Characteristics and Disparities.

OBJECTIVE: The purpose of this study was to investigate differences in clinical characteristics and health care use of Native Hawaiian and White patients with gout. METHODS: We performed a retrospective chart review of Native Hawaiian and White patients with gout treated from 2011 to 2017 within a large health care system in Hawai'i. We compared demographic characteristics, clinical outcomes, and risk factors for gout. We used multivariable logistic regression to identify predictive factors of emergency department visits. RESULTS: We identified 270 Native Hawaiian patients with gout and 239 White patients with gout. The Native Hawaiian patients were younger on average (54.0 vs 64.0 years; P < 0.0001) and had an earlier onset of disease (50.0 vs 57.0 years; P < 0.0001). Native Hawaiian patients with gout had higher mean (7.58 vs 6.87 mg/dL; P < 0.0001) and maximum (10.30 vs 9.50 mg/dL; P < 0.0001) serum urate levels compared to White patients with gout. Native Hawaiian patients with gout also had a greater number of tophi (median 2.00 vs 1.00; P < 0.0001). Native Hawaiians patients with gout were 2.7 times more likely to have frequent (≥1) emergency department visits than White patients with gout. Native Hawaiian patients with gout were less likely to have a therapeutic serum urate ≤6.0 mg/dL and had lower rates of rheumatology specialty care. CONCLUSION: Native Hawaiian patients have a higher disease burden of gout, with earlier disease onset and more tophi. Native Hawaiian patients with gout are more likely to use emergency services for gout and have lower rates of rheumatology specialty care compared to White patients. Future studies are needed to promote culturally appropriate preventive care and management of gout in Native Hawaiians.

[The management of gout]. / Vignette thérapeutique de l'étudiant. Prise en charge de la goutte.

We describe the case of a patient with a history of gout, who presents with a new episode of acute gout. Based on this clinical case, we will discuss the management of acute gout. We will then address the management of chronic gout, i.e., the indications for a hypouricemic treatment and the caution required when starting this treatment. Finally, we will address the need for a holistic care, discussing the change of certain co-medications, screening for cardiovascular comorbidities and providing diet and life-style recommendations.

Nous décrivons le cas d'un patient, goutteux connu, qui présente un nouvel accès aigu. Nous discutons tout d'abord, à partir de ce cas clinique, la prise en charge aiguë de la crise de goutte. Nous abordons ensuite les indications de mise en place d'un traitement de fond hypo-uricémiant et les précautions à prendre lors de cette introduction. Enfin, nous détaillons la prise en charge holistique, en évoquant les modifications de certaines thérapeutiques, le dépistage des comorbidités cardiovasculaires et les conseils hygiéno-diététiques.

Ozone alleviates MSU-induced acute gout pain via upregulating AMPK/GAS6/MerTK/SOCS3 signaling pathway.

BACKGROUND: Gout pain seriously affects the quality of patients' life. There is still no effective treatment. The inflammatory response is the main mechanism of gout. Here, we found that ozone can reduce the inflammatory reaction in the joints of gouty mice and relieve gout pain, and we further explore its protective mechanism. METHODS: MSU was used to establish the gouty mice model. Nociception was assessed by Von Frey hairs. Cell signaling assays were performed by western blotting and immunohistochemistry. The mouse leukemia cells of monocyte macrophage line RAW264.7 were cultured to investigate the effects of ozone administration on macrophage. RESULTS: Ozone reduced inflammation, relieved gout pain and improved the paw mean intensity and duty cycle of the gouty mice. Ozone increased the phosphorylation of AMP-activated protein kinase (AMPK), induced suppressor of cytokine signaling 3 (SOCS3) expression and inhibited metallopeptidase 9 (MMP9) expression. In vivo, ozone activated AMPK to induce Gas6 release, and upregulated MerTK/SOCS3 signaling pathway to reduce inflammation in mouse macrophage line RAW264.7. Inhibitors of AMPK and MerTK, respectively abolished the analgesic and anti-inflammatory effects of ozone in vivo and in vitro. Gas6 knockout cancelled the protectively effects of ozone on gout pain and the paw mean intensity and duty cycle of gouty mice. Additionally, the level of Gas6 and protein S in plasma of patients with hyperuricemia was significantly higher than that of healthy contrast group. CONCLUSION: Ozone reduces inflammation and alleviates gout pain by activating AMPK to up-regulate Gas6/MerTK/SOCS3 signaling pathway.

[Management of gout in the inpatient setting]. / Prise en charge hospitalière de la goutte.

Gout is a common complication occurring among inpatients, as factors affecting urate levels in blood and tissues are often modified by acute conditions. The control of chronic uricemia within recommended target values helps reduce the risk of flares. Joint aspiration is the gold standard for diagnosis, but ultrasound and dual-energy CT scan are reasonable alternatives. Acute and chronic treatments do not differ from those provided in outpatient care, although the increased prevalence of organ failures often require treatment adjustments. Active patient engagement, including therapeutic education during hospitalization, is essential for long-term disease control.

Lors d'un séjour hospitalier, les facteurs impactant la concentration sanguine et tissulaire d'urate sont souvent modifiés, augmentant le risque d'une crise de goutte. Le maintien de l'uricémie dans les cibles reconnues grâce à la poursuite des traitements contribue à réduire ce risque. La ponction articulaire est la méthode de référence pour établir le diagnostic, mais l'ultrason et le scanner à double énergie sont des alternatives fiables pour diagnostiquer une goutte. Les traitements aigu et chronique ne diffèrent pas de ceux pratiqués en ambulatoire, mais la fréquence augmentée d'insuffisances d'organes peut nécessiter l'adaptation des traitements. Pour assurer un contrôle de la maladie sur le long terme, il est essentiel d'impliquer le patient dans sa prise en charge, notamment par l'éducation thérapeutique dispensée pendant l'hospitalisation.

[Recommendations for the diagnosis and treatment of gout in China].

Gout is a metabolic disease resulting from the accumulation of monosodium urate (MSU) in joints, leading to crystal-induced arthritis. In China, gout is common, but there is insufficient knowledge regarding standardized criteria for the diagnosis and treatment of this condition. Based on evidence and guidelines from China and other countries, the Chinese Rheumatology Association developed standardized criteria for the diagnosis and treatment of gout in China. The purpose was to standardize gout diagnosis methods as well as treatment opportunities and strategies in order to reduce misdiagnosis, missed diagnosis, and irreversible damage.

Management of Gout in the Hand and Wrist.

Gout, or monosodium urate deposition disease, is the most common form of inflammatory arthritis that affects almost 4% of adults in the United States.Medical management involves lifestyle modifications and urate-lowering therapy to reduce the frequency of gout flares, decrease the tophi size, and improve upper extremity function. Goals for surgical management of gout include functional optimization, symptomatic treatment, and cosmetic restoration.This article focuses on the medical and surgical treatment of the common manifestations of gout in the upper extremity including tophi, tenosynovitis, joint contractures, neural compression, and arthropathy.

Gender differences in illness perceptions and disease management in patients with gout, results from a questionnaire study in Western Sweden.

BACKGROUND: Aims were to examine gender differences in patients with gout with regard to a) self-reported gout severity, b) illness perceptions (IP), c) impact on daily activities and Quality of Life (QoL), d) advice from healthcare professionals, e) having changed dietary- or alcohol habits. METHODS: Adult patients with gout identified in primary and secondary care in Sweden between 2015 and 2017 (n = 1589) were sent a questionnaire about demographics, gout disease severity, IP (using the Brief Illness Perception Questionnaire, (B-IPQ)) and disease management. T-tests, Chi square tests, ANalysis Of VAriance (ANOVA) and linear regression models were used for gender comparisons. RESULTS: Eight hundred sixty-eight patients responded to the questionnaire. Women, n = 177 (20%), experienced more severe gout symptoms (p = 0.011), albeit similar frequencies of flares compared to men. Women experienced modest but significantly worse IP with regard to consequences, identity, concerns and emotional response (p < 0.05) as well as daily activities such as sleeping (p < 0.001) and walking (p = 0.042) and QoL (p = 0.004). Despite this and a higher frequency of obesity in women (38 vs 21%, P < 0.001) and alcohol consumption in men (p < 0.001), obese women had received significantly less advice regarding weight reduction (47 vs 65%, p = 0.041) compared to obese men. On the other hand, women reported having acted on dietary advice to a larger degree. CONCLUSIONS: Despite only modestly worse gout severity and perception, women appear to have been given less information regarding self-management than men. These gender differences should be given attention and addressed in clinical care.

Impact of Television Depictions of Gout on Perceptions of Illness: A Randomized Controlled Trial.

OBJECTIVE: Gout is a chronic disease that can be effectively managed with long-term urate-lowering therapy. However, it is frequently portrayed on screen as an acute disease caused by a poor diet that should be managed with lifestyle changes. This study was undertaken to investigate the impact of a fictional television depiction of gout on perceptions of the disease and its management. METHODS: In a randomized controlled single-blind study, 200 members of the public watched either a 19-minute commercial television comedy episode that depicted gout as an acute disease caused by poor diet and managed with lifestyle changes, or a control episode from the same television series that did not mention gout or other diseases. Participants completed a survey regarding their perceptions of gout, its likely causes, and management strategies. RESULTS: Participants randomized to watch the gout-related episode believed gout had greater consequences (mean score of 7.1 versus 6.2 on an 11-point Likert scale; P < 0.001) and were more likely to rank the most important cause as poor eating habits compared to the control group (70% versus 38%; P < 0.001). They were also less likely to believe it is caused by genetic factors or chance. Participants watching the gout-related episode believed a change in diet would be a more effective management strategy (9.0 versus 8.4; P = 0.004) and long-term medication use would be less effective (6.9 versus 7.6; P = 0.007) compared to participants in the control group. CONCLUSION: Television depictions of gout can perpetuate inaccurate beliefs regarding causes of the disease and underemphasize effective medical strategies required in chronic disease management.

[Update Gout]. / Update Gicht.

Update Gout Abstract. Gout, the most frequent arthritis worldwide, is seldomly considered a serious chronic disease. Cardiovascular morbidity and allover mortality are increased in gout patients. Prevalence of gout is very variable in different countries and is estimated to be 2.6% overall. Men are overrepresented (3:1 to 4:1). Environmental factors, such as diet and alcohol intake, are still important, but the genetic influence, e.g., in early-onset gout, gets more and more attention. Despite the broad range of therapeutic options outcomes are poor, and the disease often leads to disabling structural damages, not only in joints. Patients' education, and the involvement of trained general practitioners and nurses will hopefully improve the outcomes of this treatable disease.
