Active clinical trials for "Arthritis, Psoriatic"

This epidemiological, transversal, cohort study aims to determine the potential influence of an active long-term hydroxychloroquine intake over the prevalence of a history of symptoms evocative of a COVID-19 infection in patients with a history of systemic lupus erythematosus, rheumatoid arthritis, Sjogren's syndrome or psoriatic arthritis, during the epidemic period in France. The information is gathered using a standardized questionnaire, by phone call.

The importance of the detection of early inflammatory arthritis is recognised as being essential to the prevention of permanent joint damage. Furthermore, drug development in inflammatory arthritis is in increasing need of imaging that is able to sensitively and accurately detect and quantify inflammation in a reproducible and objective manner. There is an increasing body of evidence to support the role of PET-CT for these indications. The PET tracer 11CPBR28 is specific to the translocator protein (TSPO) highly expressed on activated macrophages. In this proof of principle study, the investigators aim to ascertain whether or not the PET tracer 11CPBR28 is taken up in inflamed joints. The investigators also aim to explore the significance of TSPO to inflammatory arthritis, through blood and joint lining samples.

This is a prospective, open-label, 1-arm, multicenter observational study to determine the dose and time interval of Remicade (Infliximab) infusions in psoriatic arthritis (PsA).

The participants included in this observational study will be drawn from a research database containing claims and enrollment data for members of a large, geographically diverse US health plan.The objective of this study is to estimate the rate of serious infections, tuberculosis, malignancies, and other outcomes in rheumatoid arthritis, psoriatic arthritis, and ankylosing spondylitis patients treated with golimumab, anti-tumor necrosis factor (TNF) biologics, non-anti-TNF biologics, or systemic non-biological treatments.

Psoriatic arthritis (PsA) is a type of joint disease that can lead to severe joint damage and disability within the first few years of the disease. This is why early detection and treatment of the disease is essential to prevent serious joint damage and improve long-term outcomes in these patients. However, there is currently no reliable way to tell the difference between PsA and other types of joint disease. This makes it difficult to detect PsA early. Enthesitis is an inflammation of the area where muscle tendons and ligaments attach to bones. Enthesitis is a key feature in PsA and can be easily detected using ultrasonography. The aim of this research study is to develop a system to evaluate enthesitis using ultrasonography, which can be used as an effective tool in the early detection of PsA. This will help in providing patients with early treatment to prevent further joint damage.

BACKGROUND Psoriatic arthritis (PsA) is a systemic inflammatory disease with articular and extra-articular features. Establishing the prognosis of a patient with PsA is hence important to define the treatment strategy. Currently, observational and prospective cohort studies have identified prognostic factors correlating with the achievement of therapeutic response. Nevertheless, despite the importance of identifying prognostic factors in a disease with a functional disability comparable to rheumatoid arthritis, the studies are still limited. PRIMARY OBJECTIVE In PsA with clinically active joint disease starting a new course of therapy, to evaluate the additional value of UltraSound(US)-score over clinical examination in detecting patients achieving MDA at 6 months. STUDY DESIGN The study follows a multi-centre observational prospective cohort study design. PATIENTS AND METHODS INCLUSION CRITERIA Adult > 18 years of age with PsA (PsA according to the ClASsification criteria for Psoriatic Arthritis (CASPAR) - with joint involvement) At least one joint clinically involved (both swelling and tenderness); prescription of new course of d NSAIDs (monotherapy), steroid intra-articular injections (monotherapy), conventional Disease-Modifying AntiRheumatic Drugs (DMARDs), biologic DMARDs, including switches or dose augmentations indicated by the treating rheumatologist according to usual clinical practice before US acquisition; Stable treatment before treatment modification (6 weeks); Signed informed consent form. CLINICAL ASSESSMENT Patient's clinical assessment will be performed according to the core set of domains for PsA proposed by the Group for Research and Assessment of Psoriasis and Psoriatic Arthritis (GRAPPA) and Outcome Measures in Rheumatology (OMERACT). ULTRASOUND ASSESSMENT Sonographic evaluations will be performed by expert ultrasonographers in 44 joints, 36 tendons, 12 entheses and 2 bursae according to the score developed for psoriatic arthritis by the study group ultrasound of the Italian Society of Rheumatology (US-score PsA-SIR) EXPECTED RESULTS AND SIGNIFICANCE The aim of this study is to identify clinical and US predictors of achieving MDA in PsA patients with active peripheral arthritis starting a new course of therapy.

Chronic inflammatory diseases (CID) - including inflammatory bowel diseases (Crohn's disease and ulcerative colitis), rheumatic conditions (rheumatoid arthritis, axial spondyloarthritis, psoriatic arthritis), inflammatory skin diseases (psoriasis) and multiple sclerosis are diseases of the immune system that have some shared genetic and environmental predisposing factors, but still little is known on the effects of lifestyle as a prognostic factor on disease risk. This observational study will contribute to preexisting research on lifestyle factors by identifying diet factors associated with risk of developing CID, using prospective register data. The study will use data from all of the 57,053 participants in the Danish cohort "Diet, Health and Cancer (DHC)" together with registry data. Blood samples, anthropometric measures and questionnaire data on diet and lifestyle were collected at the DHC study entry. The National Patient Registry (NPR) will be used to obtain to identify patients with CID during follow-up. Follow-up information on death and immigration will be collected in March 2018 from the Danish Civil Registration Register. The outcome CID is defined as at least one of the following CIDs: Crohn's disease, ulcerative colitis, psoriasis/psoriatic arthritis, rheumatoid arthritis/ankylosing arthritis, or multiple sclerosis, during the follow-up period from 1993 to March 2018. The primary hypothesis is that "the risk of CID will be significantly higher among those with a low fibre/high red and processed meat intake compared to those with a high fibre/low red and processed meat intake." Based on previous research on a shared etiology in CIDs a second hypothesis is that "the postulated causality between low fibre/high red and processed meat intake and risk of developing CID is applicable for each of the CID-diagnoses." The core study is an open register-based cohort study. The study does not need approval from the local Ethics committee or Institutional Review Board by Danish law. The study was approved by the Danish Data Protection Agency (2012-58-0018) Study findings will be disseminated through peer-reviewed journals, patient associations and presentations at international conferences.

An observational study investigating the utilisation and effectiveness of originator and biosimilar anti-TNF agents in patients with rheumatoid arthritis, psoriatic arthritis, or ankylosing spondylitis.

The purpose of this study is to determine the mechanism of action on target tissue level of ustekinumab treatment in psoriatic arthritis patients. Patients who are planning to start treatment with anti-p40 therapy (ustekinumab) will be included in the trial. At week 0, 12 and 24 peripheral blood, synovial tissue and skin will be obtained and analysed with different techniques to assess the effect of the therapy on inflammatory pathways.

Tendon pathologies (enthesitis) are a characteristic component of psoriatic arthritis (PsA), and are observed in 35% to 50% of PsA patients. The Achilles tendon is one of the most commonly affected sites. This condition often causes great morbidity and loss of quality of life, and response only suboptimal to current intervention strategies. One of the main obstacles for the development of effective treatment methods is that the disease mechanisms remain poorly understood. To our knowledge, no one has yet ascertained the presence and function of immune-competent cells and inflammatory markers in tendons tissue from PsA patients suffering from Achilles enthesitis.
