Active clinical trials for "Gout"

The primary purpose of this study is to observe patients being treated with pegloticase in a standard healthcare setting in order to evaluate the frequency and severity of infusion reactions, anaphylaxis and immune complex related events. Additionally, serious adverse events associated with pegloticase therapy will be identified.

The aim of this study is to evaluate the efficacy and safety of simiaowan in prevention of acute flares in chronic gout patients initiating febuxostat therapy.

The study aims to identify which characteristics are associated with disability and poor quality of life in patients suffering from gout. This is a multicentre prospective observational study carried out in a cohort of Italian patients with gout. Subjects are randomly selected from a list of patients referred to each participant rheumatology clinic in the previous 2 years. Clinical evaluations are performed at baseline, at 6 and 12 months; data are retrieved about sociodemographic variables, life-styles, history of gout, comorbidities and patterns of treatment. At each visit patients complete questionnaires assessing disability and health-related quality of life. Preplanned analyses will be performed to investigate predictors of disability and poor quality of life in these patients.

This is a questionnaire study aimed at learning about physicians' views on the treatment of Gout.

The purpose of this study is to determine presence and volume of monosodium urate (MSU) crystal deposits as determined by dual-energy computed tomography (DECT) imaging in gout subjects treated with allopurinol with and without visible tophi.

Gout is a chronic disease caused by the deposit of monosodium urate (MSU) crystals in body tissues secondary to hyperuricemia. Patients with gout suffer severe attacks of acute joint pain. As the disease progresses, the joint pain becomes chronic and associated with disabling and deformative manifestations called tophus. This disease is strongly associated with several comorbidities such as cardiovascular disease and chronic kidney failure. Gout is a very common disease, which is affecting 0.9% of the adult population in France and nearly 4% of the North-American population. Data from New Zealand show a particularly high prevalence of gout among Polynesians (minority populations in New Zealand and other islands of the South Pacific) that would be explained by genetic susceptibility and frequently interrelated metabolic diseases. Data on the Polynesian population in New Caledonia suggest prevalence figures close to 7% and prevalence in French Polynesia is assumed to be higher. International genomic studies of gout and hyperuricaemia have identified alleles associated with the occurrence of gout. The aim is to focus on families with several gouty members (numerous in French Polynesia, and geographically clustered) in order to enable the study of individuals with monogenic gout or with a low number of variants (= cases) determining in the occurrence of gout, as well as a non-gouty family member (= controls). Dual-energy CT scan (DECT) allows identification and quantification of UMS crystal deposits in the tissue. The volume of crystals correlates not only with the inflammatory activity of the disease but also with the comorbidities that complicate it. Dual-energy scanning has shown the presence of UMS crystals in some hyperuricemic individuals, which could help to identify those individuals most at risk of developing the disease as they already have the stigma of sub-clinical inflammatory activity.

We will study whether the health care costs and health utilities differ in patients with gout and those without gout and whether they differ between those with more severe versus less severe gout

Patients with hyperuricemia were confirmed to have higher risks of cardiovascular disease, but the exact mechanism remained to be elucidated. Many connective tissue diseases such as rheumatoid arthritis are often associated with antiphospholipid antibodies-associated endothelial impairment. In the present study, the investigators will analyze the presence of antiphospholipid antibodies in the serum of the patients with gout/asymptomatic hyperuricemia, with a comparison to the patients of osteoarthritis but without hyperuricemia and gout. The investigators expect to find a correlation between these pathogenic antibody and those cardiovascular co-morbidities.

This study seeks to correlate microbiome sequencing data with information provided by patients and their medical records.

The main objective is to describe urate deposits (especially in terms of distribution and volume) in soft tissues and bone, and joint erosions and destruction, in adult patients with gout.
