Active clinical trials for "Arthritis, Reactive"

This study learn how easily patients can use an educational tool that will be created for patients with melanoma and pre-existing autoimmune diseases who receive or will receive immune checkpoint inhibitor drugs. Patients will be asked their opinions about the design, accessibility, and content of the tool. Researchers will use the information collected to improve the educational materials that will help patients make future decisions about their treatment.

To facilitate clinical, basic science, and translational research projects involving the study of rheumatic diseases.

This is a randomized, double-blind, placebo-controlled trial of the effect of 3-month treatment with the combination of 200 mg ofloxacin twice daily and 150 mg roxithromycin twice daily on clinical course of recent-onset reactive arthritis. Patients are followed-up at regular intervals until 6 months. The main outcome measure is recovery from arthritis, and secondary outcome measures include swollen and tender joint counts, Ritchie index, joint pain, serum C-reactive protein level and blood erythrocyte sedimentation rate. The study will also address the safety and tolerability of long-term antibiotic treatment. 56 patients are enrolled and the enrollment of patients has been completed.

Reactive arthritis, also known as Reiter's syndrome, is a form of arthritis that occurs as a reaction to an infection elsewhere in the body. It is characterized by inflammation of the joints, tendons, urogenital tract, and eyes. Pain and swelling in the knees, ankles, and feet are common. This study will determine the effectiveness of antibiotic therapy in treating people with chlamydia-induced reactive arthritis that has lasted for more than 6 months.

The purpose of this study is to develop evidence on the relative efficacy of 2 rifaximin chemoprophylaxis regimens for the prevention of Travelers' Diarrhea (TD) in a deployed setting. An additional purpose is to explore the effect of chemoprophylaxis on microbial flora and antimicrobial resistance, and obtain parameter estimates to inform a cost-effectiveness model of chemoprophylaxis in prevention of TD. Information from this study will be used to develop management guidelines for the prevention of TD among deployed (United States (US) and United Kingdom (UK) military personnel. The study will be a multi-site, randomized, placebo-controlled, double-blind, clinical trial among deployed military personnel. The study will test 2 TD chemoprophylaxis regimens (once daily versus twice daily) of the same antibiotic, rifaximin, compared to a placebo. For the proposed chemoprophylaxis study described herein, cohorts of military personnel (US and UK) deploying/traveling overseas will be recruited prior to travel to participate and will undergo enrollment procedures as outlined in study appendices. Subjects who are eligible and agree to participate will be randomized to receive one of 3 regimens: (1) rifaximin 550 mg daily; (2) rifaximin 550 mg twice a day; or (3) placebo, to be taken while deployed. Chemoprophylaxis will be maintained for duration of travel or a predetermined period of up to 6 weeks and at least 2 weeks, which may include a period of up to 5 days of use after return to COO for deployments less than 6 weeks in duration. Clinical and laboratory data will be obtained before, during if available and after deployment/chemoprophylaxis.

This is a Phase 1 dose escalating study to assess the safety, tolerability, and immunogenicity of ShigETEC, a live, attenuated Shigella/ETEC combination vaccine given orally to healthy European adults 18 to 45 years of age. The major aim is the development of an efficacious and safe vaccine that prevents diarrhea caused by Shigella and ETEC in travelers, military personal visiting endemic countries and children of the developing world. This Phase 1 safety and immunogenicity study used a double-blind, placebo-control design and was conducted in two stages, a single ascending and a multiple ascending stage.

The Chinese Spondyloarthritis Inception cohort (CESPIC) was started 2000 as a prospective, longitudinal, multicentre, nationwide study in China on patients with early SpA including ankylosing spondylitis (AS, also known as radiographic axial spondyloarthritis) and non-radiographic axial SpA. The objectives of CESPIC are to learn about the course of SpA during the very early stage of the disease, to appropriately assess the outcome including radiographic progression of patients after several years of follow-up, to identify outcome predictors, to assess quality of life, function, and costs (direct and indirect costs). CESPIC has been recently expanded to recruit patients with other forms of SpA / conditions associated with SpA: reactive arthritis, acute anterior uveitis, Crohn's disease as well as with psoriasis / axial psoriatic arthritis.

Post-acute sequelae of SARS-CoV-2 infection can cause multiple system function disorders, and complicated symptoms last for an extended period. The virus can cause this continued infection, or the virus causes immune system function disorder and post-infectious autoimmune disease. The clinical symptoms can be smell loss, taste loss to liver function disorder, kidney function failure, different. No matter how complicated the systems showed in the clinic, all of the symptoms are due to the specific cells being damaged. Our clinical study is focused on recovering the damaged structure and function of the cells that could restore the organ function back to normal or close to normal

People with inflammatory diseases treated with immune-suppressing medication are recommended to have regular blood-tests to monitor for potential side-effects of this treatment on their blood count, liver and kidneys. However, it is not clear that monitoring is needed as frequently as currently recommended in the long-term, with side-effects being rare after one year of treatment. A study is currently underway to determine the optimal blood-test monitoring strategy which is cost-effective but still safe. Any changes in the monitoring strategy must be acceptable to patients and the healthcare professionals (HCP) that treat them. This study aims to measure how often patients' with common inflammatory conditions on long-term immune suppressing medication attend their monitoring blood tests as currently recommended, and uncover patients' and HCP views and experiences of the current blood-test monitoring strategy, and the acceptability of potential changes to this in the future. Firstly, patients with an inflammatory condition on long-term immune suppressing treatment will be invited to complete a questionnaire which will ask about their demographic information, medical condition(s), immune-suppressing treatment, adherence to the monitoring blood tests and willingness to take part in an interview. Then, both patients and HCPs who care for such patients will be invited to take part in a single, semi-structured interview. Interviews will be face-to-face, by telephone or video-call, last up to one hour and digitally audio-recorded. Patient interviews will explore their perceptions of risk, benefits and experiences of current testing, and views on the new testing frequencies emerging from the study prior. HCP interviews will explore their perceptions of current testing including, the practicalities, usefulness, risks and benefits of the blood tests, and views on the new testing frequencies emerging from the study prior. The findings will shape the recommendations for a new monitoring strategy, ensuring it is acceptable to patients and HCPs.

People with inflammatory diseases are often treated with medications that act to suppress the immune-system, increasing the risk of catching infections. Consequently, vaccination with the pneumonia and seasonal flu vaccines is recommended for them. They were also prioritised to receive the COVID-19 vaccines early in the national rollout. However, the uptake of the pneumonia and seasonal flu vaccines among this group is lower than ideal. There may be many reasons why they do or do not seek to be vaccinated for these infections, such as the belief it may cause their disease to flare up or lack of knowledge of vaccines effectiveness. Anecdotally there was a high uptake of COVID-19 vaccines in adults with inflammatory conditions, however, concerns about vaccine-induced disease flare-ups and reports of complications deterred some from being vaccinated. A better understanding of why people do and do not seek vaccination may result in more targeted messaging for patients to help overcome vaccine hesitancy for these infectious diseases. This study aims to explore the drivers and barriers to being vaccinated among adults with common inflammatory conditions and on immune-suppressing medication. They will be invited to participate in a single, semi-structured interview. Interviews will be face-to-face, by telephone or video-call, last up to one hour, and digitally audio-recorded. They will explore participants' understanding of pneumonia, seasonal flu and COVID-19 and the risk they pose to their health, their understanding of vaccinations, beliefs of the benefits and risks of vaccinations for these infections, and reasons for seeking or not seeking vaccination. Findings will inform messaging about being vaccinated for these infections in patient education leaflets, such as those by patient charities regularly provided at speciality clinics. They will also be disseminated to healthcare professionals to help them better understand the drivers and barriers to vaccination.
