An Innovative Chinese Herbal Formula for the Treatment of Gout

Gout is a chronic disease of deposition of monosodium urate crystals, which form in the presence of increased urate concentrations. Gout is closely related to hyperuricaemia. Urate deposits in the joint, causing joint swelling, pain, movement disorders, affecting a significant portion of the population worldwide annually. The underlying pathophysiology of gout is multifactorial, complex, and poorly understood. Thus, gout remains one of the major therapeutic challenges. Currently, western medicine treatment of gout flare includes colchicine, NSAIDs and glucocorticoids. These drugs act as analgesics, anti-inflammatory and uric acid lowering drugs. Besides, management of gout and prevention of acute flares of gout make a crucial part in gout management. To obtain uricemia target, urate lowering treatment (ULT) has been widely used in conventional management of gout. Allopurinol, probenecid and febuxostat are some of the examples of ULT. Although researchers have carried out various studies on this disease, there are severe side effects for patients with gout. Therefore, it is necessary to explore new treatments for gout with good efficacy and less side effects. Chinese medicine (CM) is nowadays widely used for managing gout in China and other East Asian countries. Our principal Investigator (Prof. Zhi-xiu Lin), a highly experienced Registered Chinese Medicine Practitioner working at the School of Chinese Medicine, The Chinese University of Hong Kong, has been using a herbal formula (HKIIM-KU formula) to treat patients with gout in Hong Kong for many years. This formula has been observed to be effective in relieving and preventing gout and its related clinical manifestations. Hence, a double-blind, randomized, placebo-controlled, multicenter clinical trial will be employed in this study, and it would be able to provide robust clinical evidence on the efficacy and safety of HKIIM-KU formula for gout.

D-0120 is being tested in combination with Allopurinol in adult subjects with Gout.

To Evaluate the Influence of (LUA Probiotics) on Uric Acid

This study aims to investigate the efficacy of the lactic acid bacteria "LUA probiotics" in reducing serum uric acid levels. The use of health supplements prior to the onset of gout symptoms is proposed as a preventive strategy to mitigate the development of gout and to reduce the subsequent reliance on long-term pharmacological treatments. Hyperuricemia is the presence of abnormally high levels of uric acid in the blood serum. Long-term hyperuricemia is a major factor in causing gout. In addition, hyperuricemia is associated with many diseases. Therefore, the prevention and treatment of hyperuricemia has gradually attracted attention. In recent years, studies have pointed out that whether from cell experiments or animal experiments, lactic acid bacteria (LAB) have the effect of lowering uric acid. However, there is a lack of rigorous clinical observational studies to further explore whether lactic acid bacteria really have the effect of lowering uric acid. This product "LUA Probiotics" is a probiotic developed and produced by the Longtan Branch of Grape King Biotechnology Co., Ltd. Its main ingredients include Lactobacillus reuteri (Lactobacillus reuteri), β-carotene, silicon dioxide and magnesium stearate. This product is not yet commercially available.

Musculoskeletal Ultrasound for Differentiating Rheumatoid and Gouty Arthritis

Rheumatoid arthritis (RA) and gouty arthritis (GA) are two common forms of joint inflammation that can present with very similar physical symptoms, making them difficult to tell apart early in the disease process. Accurate and early differentiation is crucial because the treatment strategies and long-term management for the two conditions are substantially different. The primary purpose of this observational study is to evaluate the diagnostic performance of musculoskeletal ultrasound (MSUS) in distinguishing between RA and GA. Ultrasound is a safe, radiation-free imaging tool that can visualize joint inflammation and structural changes in real-time. This study utilizes a structured semi-quantitative scoring system (graded on a scale of 0 to 3) to systematically measure the severity of joint lining thickness (synovial hypertrophy) and active blood flow (power Doppler signal). It also checks for crystal-related deposits, such as tophi or the double contour sign, which are highly suggestive of gout. Participants aged 18 and older with suspected or confirmed RA or GA who are referred for joint assessment at Assiut University Hospitals will undergo a standard clinical evaluation, routine laboratory testing, and an ultrasound examination of specific target joints (such as the wrists, hands, knees, and ankles). By comparing the ultrasound scores and specific structural findings between the two patient groups, the study aims to establish a reliable, standardized imaging approach to help physicians make faster, more confident diagnoses and initiate the correct disease-specific therapies sooner.

Immediate Prescription of a Hypouricemic Treatment, Febuxostat, Compared to Its Delayed Administration

Gout, the most common inflammatory rheumatism in France, is a complication of chronic hyperuricemia (\> 360umol / l). The resulting urate crystals are deposited in many tissues, especially the skeletal or kidneys. It appears in the form of spontaneously regressive inflammatory joint attacks in 5 to 7 days but recurrent. Gout turns into a chronic disease if uric acidemia is not reduced, and is responsible for joint destruction. It becomes a vector of renal failure and is associated with cardiovascular morbidity and a reduction in life expectancy. It is cured if a long-term treatment such as febuxostat leading to the normalization of the uric acidemia is administered. However, the frequency of this disease is increasing in industrialized or emerging countries. The causes are numerous, particularly food, but also related to flaws in therapeutic care. Studies show that this treatment is not taken in particular because, after the acute attack, the patient who has become asymptomatic again no longer consults. Currently, in a traditional way and according to European recommendations, it is not prescribed until several weeks after the acute attack in order to avoid early relapses, which would then be more numerous. Nevertheless, even if the hypouricemic agent is prescribed late , the attacks can be repeated and become rare for several months after obtaining a uricemia below 360umol / l; they eventually disappear. Lack of knowledge of this disease largely affects the hazards of disease-modifying treatment, which alone can prevent the progression to chronic inflammatory disease and its cardiovascular and renal impact and on mortality. One of the causes of not taking a hypouricemic agent is its delayed administration. This study is proposed to assess the relevance of early initiation versus delayed administration of such treatment.

Using Gout Buddy to Enhance Gout Management

Background: Dietary management is crucial for gout, but patients often lack adequate dietary literacy. However, patients often lack adequate dietary literacy and struggle to navigate complex dietary recommendations. Gout Buddy is an autonomous AI agent to offer personalized gout education and awareness tailored to individual needs. This study aims to evaluate the effectiveness and user experience of Gout Buddy, in improving dietary literacy and gout management. Materials and methods: A two-arm RCT will randomize patients with gout to either the intervention (Gout Buddy) or control (standard care). Two study visits within 3-6 months will assess changes in dietary literacy and gout management behaviours. Qualitative interviews will be conducted with intervention arm participants and multidisciplinary care team members to explore their experiences with Gout Buddy till the point of data saturation. Expected Outcomes: The current trial is expected to demonstrate the effectiveness of Gout Buddy in improving dietary literacy and gout management compared to standard care. Qualitative data will provide rich insights into user engagement, perceived benefits, challenges, and the feasibility of integrating the chatbot into routine gout management. Significance: This study will provide evidence on the potential of AI chatbots to enhance gout self-management. The findings will inform the development and implementation of digital health tools for chronic disease management, potentially improving patient outcomes and reducing the burden of gout.

Gout in the ED and Improving Research Participation

The prevalence of gout has been steadily increasing over several decades and is correlated with the rising burden of obesity, chronic cardiac and renal disease; all conditions overrepresented in the Southeastern U.S. - particularly in African Americans. Through a novel emergency department led intervention we aim to improve the care patients with gout receive, both during acute exacerbations and long-term. A secondary goal of the project is to concurrently enhance participation of minorities in biomedical research in the Deep South.

To determine the feasibility of a patient self-management app for patients with gout receiving GP follow-up. 2. To determine the feasibility of conducting a future randomised controlled trial to test the effectiveness of the app for patients with gout in primary care. Participants will be asked to test the self-management app for 3 months. Data will be collected from the participants and their GPs.

the Effects of Febuxostat Dose Tapering in Gout Patients Optimally Controlled for 5 Years or More

The goal of this clinical trial is to compare the changes in serum urate levels and symptom recurrence after reducing or suspending urate-lowering agents in well-controlled gout patients (the 'after dishes are clean' state in the Dirty Dish hypothesis) Researchers will compare three randomized groups: the reducing group takes febuxostat 20 mg once daily for 12 months, the discontinuing group takes a placebo once daily for 6 months, followed by febuxostat 20 mg once daily for the next 6 months, and the maintaining group continues their pre-study urate-lowering agents for 12 months, serving as an observational reference group. During the 12-month study period, participants will visit every 3 months for laboratory evaluations including serum urate levels, and for checking symptomatic status using questionnaires and diaries. Additionally, musculoskeletal ultrasonography and serum sample collection will be performed at baseline to study predictors for maintaining serum urate levels \<7.0 mg/dL after reducing or suspending urate-lowering therapy.

Study of the Correlation Between UltraSonography and Dual-Energy Computed Tomography Assessment of Urate Deposit

The objective of this research is to evaluate the correlation between DECT and US explorations performed in a routine clinical setting for the measurement of change in tophus size in gout patients after 24 months of treatment.

Long-Term Risk of Gout in Living Kidney Donors

This population-based, matched, retrospective cohort study will evaluate the long-term risk of gout among living kidney donors compared with matched healthy nondonors, using linked administrative health care databases from Ontario, Alberta, and British Columbia. Living kidney donors who donated between 1992 and 2024 will be identified and matched 1:10 to a carefully selected population of healthy nondonors based on baseline characteristics. The primary outcome is the first health care encounter with a diagnosis of gout. Secondary outcomes include receipt of a dispensed prescription for the composite of allopurinol, colchicine, or febuxostat, and each medication separately. The findings will provide evidence to inform clinical guidelines, support informed decision-making among potential donors and recipients, and guide counselling by transplant clinicians.

This is a open-Label, Within-Subject Drug-Drug Interaction Study of ABP-671 Added to Stable Allopurinol Therapy in Gout Patients. Pharmacokinetic (PK) interaction between ABP-671 and Allopurinol will be evaluated in participants who are on stable Allopurinol therapy.

Tight Control of Gouty Arthritis Compared to Usual Care

Gout is caused by a reaction to urate crystals that results in attacks of severe joint pain. Medicines that lower urate levels can prevent gout flares, however it takes time for this benefit to be felt, and paradoxically starting treatment with large doses of urate lowering treatment risks provoking attacks of gout. Medical guidelines disagree on the best way to overcome these challenges with many recommending medicine dose adjustment based on regular urate testing but a general practice guideline suggesting more simply increasing the medicine dose in those patients that continue to suffer flares. In reality most patients are not treated at all, and many of those that are treated never receive an effective dose of treatment. We have developed a supported self-management approach to gout in which patients monitor their own urate levels using a finger prick test, and then receive advice on adjusting their treatment dose to achieve target urate levels through a smartphone app (Gout SMART). A trial of this approach has shown that it results in much better control of urate levels after 6 months than usual care, and suggests that it also leads to fewer flares. We would now like to confirm that this approach is effective in reducing flares of gout over 2 years by randomising patients to either treatment-to-target urate using our self-monitoring approach, or to usual care.
