Active clinical trials for "Arthritis"

The purpose of the study is to evaluate the pharmacokinetics and safety of certolizumab pegol in adults with active rheumatoid arthritis.

This study included 76 newly diagnosed RA patients and 50 matched controls. Basal JAK2 mutation was assessed by PCR in blood samples, TNF-α and IL 6 were measured by ELISA in serum of patients and controls. All patients started therapy with conventional synthetic DMARDs (including methotrexate). Response assessment at 3rd month was evaluated by DAS28 and ACR response criteria. JAK2 mutation was correlated with different clinical and laboratory parameters of patients.

The purpose of this project is to pilot test the effect of a tablet-based cognitive behavioral intervention (Tab-CBI) application on older adults' a) daily steps, b) fatigue level, c) self-efficacy, and d) quality of life at Week 1 (baseline), Week 4 (intervention completion), Week 6 (booster), Week 8 (follow-up #1), and Week 10 (follow-up #2) in a sample of 24 older adults. The investigators hypothesize that (a) individuals receiving Tab-CBI will have increased daily step counts, decreased fatigue level, greater perception of self-efficacy and quality of life than those receiving current RA fatigue management, and that (b) the effects will be sustained up through 4 weeks of follow-ups after the intervention completion.

Peer support (including informational, emotional, appraisal support) has been shown to help persons with chronic conditions. The goal of this research is to examine the impact of early peer support on the health and quality of life of individuals with early inflammatory arthritis (EIA). The investigators hypothesize that early peer support will result in improved use of disease modifying anti-rheumatic drug (DMARD) or biologic treatment, self-efficacy, coping efficacy, social support, health-related quality of life, self-management, and disease activity score as well as reduced anxiety for individuals with EIA within two years of their diagnosis. In this study, persons with IA will be trained as peer mentors using a training program developed for a pilot study. Individuals with EIA will be randomized to receive either "peer support program" or "standard care". Peer mentors will be paired with a person with EIA to provide one-on-one support (face-to-face or telephone) once a week for approximately 30 minutes over a 12-week period. All "standard care" participants will receive the peer mentoring intervention at the end of study. Both groups will be evaluated using self-administered questionnaires and clinical assessments, and results of the two groups will be compared. This information will be used to design a larger study.

The purpose of this study is to evaluate the effects of a group-based exercise and educational program for people with Rheumatoid Arthritis (RA) on physical performance and disease-self-management.

In this study, a 10 mg tasocitinib (CP-690,550) tablet will be administered to healthy subjects on two separate dosing occasions. On one occasion the tasocitinib (CP-690,550) tablet will be administered in a fasting condition; On the other occasion the tasocitinib (CP-690,550) tablet will be administered in a fed condition following a standard breakfast meal. The amount of tasocitinib (CP-690,550) in the blood will be measured at various times over 24 hours following each dosing occasion and compared to evaluate for any differences.

We will evaluate the bioavailability of naproxen 375 mg in two formulations

Background: The safety of vaccination in patients with autoimmune diseases using immune suppressive therapy is often discussed. Previous studies in Juvenile Idiopathic Arthritis (JIA) patients showed no increase in disease activity after immunisation with dead vaccines. The safety of the live attenuated Measles, Mumps, Rubella (MMR) vaccination was assessed retrospectively in JIA patients and no increase in disease activity was found. However, this must be prospectively confirmed. In addition, it is unknown whether vaccination is effective, since the immune response to vaccination may be diminished due to immunosuppressive therapy for the underlying disease. Finally, the influence of MMR vaccination on the immune system of JIA patients has not been studied. Among others, regulatory T-cells (Tregs) should control the immune response and prevent destructive autoimmune responses after environmental triggers such as vaccination. Objective: The aim of the present study is to investigate the safety and efficacy of the MMR booster vaccination and its influence on immune regulatory mechanisms in children with Juvenile Idiopathic Arthritis. Method: JIA patients aged 4 to 8 years and treated by the pediatric rheumatology units from various University Medical Centers in the Netherlands, are asked to participate in a prospective study. In the Netherlands, measles-mumps-rubella (MMR) vaccination is included in the National Vaccination Program and is normally administered at age 9. Included patients will be randomised for early vaccination (age group 4 to 8yr at entry of the study) or at age 9 as is routinely done according to the National Vaccination Program. Prior to and after vaccination the investigators will assess disease activity and collect blood. Outcome: During a 12 month follow-up period the investigators will register disease activity and side-effects at different moments in time to determine safety of vaccination. The efficacy of the vaccine will be studied according to antibody levels and function against measles, mumps and rubella in the blood. Tregs will be isolated and their functionality will be determined using the blood cells collected during follow-up. This enables us to study the role influence of vaccination on regulatory mechanisms in our immune system.

Osteoclastic bone resorption depends on both the capacity to generate osteoclasts (osteoclastogenesis) and on individual osteoclast activity. The investigators objective is to study the effect of anti-TNF therapy on the number of osteoclast precursors in the peripheral blood of patients with Rheumatoid Arthritis, on in vitro osteoclastogenesis and on osteoclast activity before and during the treatment of patients with Rheumatoid Arthritis with Adalimumab.

The purpose of this pilot study is to investigate the possibility of discontinuing adalimumab therapy in patients with rheumatoid arthritis who are in stable remission after treatment with adalimumab in combination with methotrexate.
