Active clinical trials for "Arthritis, Psoriatic"

Prospective study to investigate the correlation between CD39/CD73 expression by the different T lymphocyte subpopulations in the blood and synovial fluid (if available) into patients with chronic inflammatory rheumatism RA and PsA types, with the rheumatic activity, the background therapy (with Methotrexate (MTX)) and the response to this treatment.

The aim of this observational study will be to recruit 100 Psoriatic Arthritis (PsA) patients beginning on their biologic therapy and asses, both clinically and with the use of ultrasound (US), how enthesitis responds to biologic treatment. The decision to start treatment with a biologic therapy will be made by the patients' usual clinical rheumatology team, as part of their standard clinical care. This is independent of the study. Patients in whom treatment with these drugs for their PsA has been recommended will then be invited to participate in this study.They will then be commenced on biologic therapy at doses in line with the Summary of Product characteristics (SPC) for the product and followed up in the hospital outpatient clinic. Patients will have a full history taken and clinical exam performed prior to commencing on their prescribed biologic. The patient's history, Health Assessment Questionnaire scores and biobanking samples will be taken by the co-investigator. They will also calculate the patients tender and swollen joint score, dactylitis score, skin score, nail score and clinical enthesitis score.They will then have their tender entheseal points scanned as well as those as per the MASEI (Madrid Sonographic Enthesitis Index ) protocol by a single rheumatologist. The rheumatologist will be trained in ultrasound and will perform the scans blinded to this information both at initial consultation and at subsequent reviews. The patient will then commence their biologic treatment as planned at a separate review as per usual practise with their clinical team. Follow-up and final assessment at 4 months (±2 weeks) after starting biologic will include the clinical and ultrasound assessments as per the initial review and outlined in the schedule of assessments. They will also have a final blood sample taken at this point.

Observational, prospective and multicenter study in approximately 25 sites nationwide. The investigators participating in this study will be rheumatologists specializing in this pathology. The study will include patients diagnosed with PsA (according to the CASPAR diagnosis criteria), naïve to biological treatments, who have - following the routine practice in their centers - initiated treatment with apremilast 6 months (±1 months) before their inclusion in the study, irrespective of treatment duration. Recruitment will be consecutive and the reason for not including a potential candidate patient will be registered. The decision to prescribe apremilast treatment should be clearly dissociated from the inclusion of the patient in the study, which will not occur earlier than 6 months (± 4 weeks after treatment start). Therefore, the choice of the therapeutic strategy will be made independently by the physician. Before entering the study, all patients shall sign an informed consent to participate in the study, including permission to retrieve data from their medical records and to complete questionnaires regarding their quality of life. To avoid recruitment biases and obtain a homogeneous cohort regarding treatment duration, all consecutive patients who attend to a routine follow-up visit and have been prescribed apremilast 6 months (+/- 4 weeks) before the baseline visit, will be offered to enter the study. All consecutive patients who can be contacted 6 months (+/- 4 weeks) following initiation of treatment with apremilast will be approached for entry to minimize bias in patient selection

Inflammatory arthritis such as rheumatoid arthritis (RA) and psoriatic arthritis (PsA) are characterized by synovial inflammation of joints, potentially leading to joint destruction and functional disability. Inflamed joints have lower oxygen levels. Studying how oxygen level within the joint affect inflammation may lead to new treatments for patients with arthritis. Anti-inflammatory corticosteroid injection into the joint is well tolerated and widely used in clinical practice but its effects on oxygen level within joints is unknown. Therefore, patients who require corticosteroid injection into the joint as routine clinical care will have biological samples collected before and after the injection. This will give new information to put into context the biological effects within the joint, and accelerate development of new treatment approaches in the future.

In this open-label, multi-center, observational, post-marketing surveillance study, patients with ankylosing spondylitis, psoriatic arthritis, or rheumatoid arthritis received biosimilar etanercept 25 mg twice weekly or 50 mg once weekly in real-world settings. Safety and effectiveness of biosimilar etanercept were evaluated in study participants for a duration of up to 12 months.

Rheumatoid and psoriatic arthritis patients benefit from anti-TNF-α therapy, once it is effective in reducing joint and skin manifestations in 60-70% of patients with inflammatory articular joint and skin diseases. Thus, identifying the presence and amount of TNF-α in the joint or skin in these patients may help in guiding the course of treatment more efficiently. The investigators research group has developed a novel approach to label anti-TNF-α with technetium-99m. Here the investigators compare the results obtained with scintigraphy and MRI in rheumatoid and psoriatic arthritis. The 99mTc-anti-TNF-α scintigraphy might recognize the molecule involved in the inflammatory process and provide crucial information to help physicians taking decisions about the drugs to be used based on biological evidence and which are cost-effective and appropriate for the treatment of choice. It allows direct identification of the monoclonal antibody anti-TNF-α in the articular joints and skin while it also ensures that the drug has reached its therapeutic target. It also allows correlation between the presence of the drug and clinical responses.

This post marketing observational study is designed to provide the initial data on work impairment of PsA patients in Turkey, as well as changes in work impairment, life quality and clinical response during treatment with anti-TNF agents.

This 12-month postmarketing observational study (PMOS) was a prospective, single-arm, multicenter, multi-country study, with follow-up visits at 3, 6, 9, and 12 months after the initial baseline visit. The study was conducted to determine the long-term effectiveness of treatment with adalimumab in routine clinical use in participants with Ankylosing Spondylitis (AS) and Psoriatic Arthritis (PsA) in Central and Eastern European Countries.

This is a non-interventional, post-marketing, observational study (PMOS) in which Humira (adalimumab) is prescribed in the usual manner in accordance with the terms of the local marketing authorization with regards to dose, population and indication. No data currently exists to characterize patient populations being prescribed Humira in Eastern Europe. Further, it is important to establish the clinical outcome and tolerability of Humira in Eastern European patients, as well as their compliance with Humira treatment, in particular the acceptability of self-injection, which may influence all of the above in routine clinical practice.

This is a five year, post-marketing observational study to follow-up patients with rheumatoid arthritis, psoriatic arthritis or ankylosing spondylitis who are treated with HUMIRA (adalimumab).
