Active clinical trials for "Arthritis, Rheumatoid"

A review of the literature reveals that very few studies have assessed the potential co-existence of vitamin B12 deficiency due to gastric parietal cell autoantibodies. While Segal et al. in 2004 published a study which found that 49% of patients with RA had vitamin B12 deficiency, no assessment of the etiology or the presence of autoantibodies was made. While Goeldner et al. in 2011 and Datta et al. in 1990 demonstrated that anti-gastric parietal cell antibodies (anti-GPC Ab) were found in <5% to 28% of RA patients respectively, no additional testing was implemented to determine the significance, specifically whether or not the presence of anti-GPC Ab related to vitamin B12 deficiency. The purpose of this study is to determine the prevalence and metabolic significance of anti-GPC Ab in three cohorts: (1) a group of patients with Rheumatoid Arthritis, (2) a group of patients with autoimmune thyroid disease (AITD), and (3) a group of patients with neither RA or AITD. To determine the significance of the presence of anti-GPC Ab, testing of the current serum B12 level along with a metabolite dependent on adequate vitamin B12 levels (Methylmalonic acid) will be tested.

This multicenter, observational study will evaluate the use and efficacy of RoActemra/Actemra (tocilizumab) in routine clinical practice in patients with moderate to severe rheumatoid arthritis. Eligible patients initiated on RoActemra/Actemra treatment in accordance with the local label will be followed for 6 months.

Backgound and relevance of the project: Patients with autoimmune inflammatory rheumatic diseases (AIIRD) are at increased risk of contracting infections. The increased risk can be attributed to the immunological disorder itself, as well as to the immunosuppressive treatment. Vaccination against many infections is recommended in this patient group. However, the immunogenicity of vaccines may be reduced and may also be influenced by the administered treatment. Potential reactivation of the underlying disease triggered by vaccination is another important concern. From the patients' and public health perspectives, an important task of physicians is giving advice on vaccines. Completing this task is often difficult, because data on the immunogenicity and safety of vaccines in these patient groups are scarce, especially with regard to treatment with new immunosuppressive medications, such as biological agents. Lastly and importantly, due to new therapeutic options, health among AIIRD patients has considerably improved and an increasing number of patients undertake overseas travel activities requiring additional vaccinations. In this context, reliable advice with regard to vaccinations is almost impossible, because for most travel vaccinations the immunogenicity and safety profile is unknown. Research addressing the immunogenicity and safety of vaccines in different autoimmune inflammatory diseases treated with different immunosuppressive medications is urgently needed to allow giving evidence based vaccine advice. In this observational study the immunogenicity and safety of tetanus booster and hepatitis A vaccinations will be assessed in AIIRD patients. The immune response will be evaluated as a function of the underlying disease and the possible influence of commonly used immunosuppressive drugs on the immune response will be studied. Rationale for studying tetanus booster and hepatitis A vaccine Tetanus vaccination is one of the most frequently recommended vaccinations, and the effect of a booster vaccination can be addressed. Hepatitis A vaccine is the most widely used travel vaccine. Despite their importance, only very limited data are available for tetanus and hepatitis A vaccine in this patient group. By focusing on these vaccines the study will lead the way to the evaluation of further vaccines. The purpose of this study is to determine whether tetanus and hepatitis A vaccinations are as immunogenic and safe in AIIRD patients as in healthy controls.

The purpose of this study is to understand how personalized risk factors for rheumatoid arthritis (RA) may impact willingness to change behaviors associated with RA. The investigators have developed a personalized risk estimator for RA based on demographics, family history, biomarkers and behaviors related to RA risk. Eligible participants have a first degree relative with RA but do not have RA themselves. Participants who meet eligibility and consent to the study will be randomized to receive either standard information about RA, the online personalized RA risk tool, or the online personalized RA risk tool with guidance from a health educator. Participants will be followed to measure willingness to change RA risk behaviors. The investigators hypothesize that participants who receive the online personalized RA risk tool and health education will be more willing to change RA risk behaviors compared to participants that receive standard RA information.

This observational study will evaluate the long-term efficacy and safety of RoActemra/Actemra (tocilizumab in participants of the ACT SURE clinical trial and further patients with moderate to severe rheumatoid arthritis starting or receiving RoActemra/Actemra. Data will be collected from each patient for up to 4 years.

This multi-center observational study will evaluate the use and efficacy of RoActemra/Actemra (tocilizumab) in patients with moderate to severe rheumatoid arthritis. Eligible patients initiated on RoActemra/Actemra treatment according to the licensed label will be followed for 6 months.

Studies have shown that people with rheumatoid arthritis (RA) have a higher rate of heart disease than people that do not have RA. we believe this is caused by the inflammation produced by RA.

This is an open-label, uncontrolled, observational study in patients with rheumatoid arthritis (RA) who are receiving tocilizumab concomitantly with methotrexate as part of their standard of care.

This prospective, observational study will assess the effect of RoActemra/Actemra (tocilizumab) on fatigue in patients with moderate to severe rheumatoid arthritis who have an inadequate response to disease-modifying antirheumatic drugs (DMARDS) or anti tumor necrosis factor (anti-TNF) drugs. Eligible patients receiving RoActemra/Actemra according to the standard of care will be followed for 4 months.
