Filter by:This study aimed to develop two poly herbal capsule formulations for arthritis through granulation and conduction of their clinical trial in order to achieve quality, efficacy and safety. Arthritis is a chronic disease of unknown cause. An inflammatory disease of the synovium, it results in pain, stiffness, swelling, deformity and, eventually, loss of function in the joints. Despite early detection, current treatment medications are limited in their efficacy and are frequently toxic. Many patients look for complementary and alternative medicine (CAM) options in coping with this debilitating disease. Research has indicated that people suffering from chronic pain, as in arthritis, and those dissatisfied with current treatment are very likely to seek alternative treatments, and an estimated 60-90% of persons with arthritis use complementary and alternative medicines. Among the most widely used treatments are chiropractic and herbal therapies. This growing interest in alternative medical practices clearly indicates the need for more thorough investigation into the safety and efficacy of herbal medicine. Thousand years of traditional use can provide us with valuable guidelines to the selection, preparation and application of herbal formulation. To be accepted as viable alternative to modern medicine, the same vigorous method of scientific and clinical validation must be applied to prove the safety and effectiveness of a therapeutical product.
Rheumatoid arthritis (RA) is one of the most common autoimmune inflammatory arthritis affecting 0.5 to 1% population worldwide characterized by synovitis, increased inflammatory markers and progressive bone and cartilage erosion. RA is associated with an increased cardiovascular morbidity and mortality compared with the general population.
Rheumatoid arthritis (RA) is an autoimmune and sistemic disease,characterized by joint sinovitis and the production of autoantibodies (Ab). The Ab against citrullinated peptides (ACPA) are the most specific (92-98%), and high sensitivity (75-81%) and they are of prognostic value. ACPA are already in the beginning of the disease in most cases, having been found years before its onset. Recent studies have suggested that ACPA may have a role in perpetuating inflammation, in the generation of bone erosions and in pain in RA. Citrullination is a post-translational modification mediated by the PAD, which transforms an arginine into a citrulline. In vivo, this enzyme acts in proinflammatory environments. Despite being widely studied, none of the natural citrullinated substrates have been shown to be the triggering and/or perpetuating factor in the response of B cells in RA, understanding this response as the production of ACPA. In fact, the most specific and sensitive commercial test for the detection of ACPA uses synthetic peptides protected by a patent. In the other hand, the genetic factor that most increases susceptibility to develop RA is a shared sequence of aminoacids (QKRAA, QRRAA i RRRAA), in the HLA-DRB1 gene, known as the shared epitope (SE). Also, SE, confers prognostic value, and is associated with the presence of ACPA. These SE sequences contain arginines (R), which are susceptible to be citrullinated by the PAD enzyme. We propose the hypothesis that citrullinated SE act as an antigen capable of activating the inflammatory response mediated by B and T cells in RA. The recognition of an HLA as a foreign one, would originate an answer of alloimmune type, not valued to date. The objective of the study is to test the immune response mediated by B cells and T cells, in cases and control samples, through an in vitro model that confronts them with peptides containing the citrullinated-SE sequence. In addition, we will evaluate the association between these results with the clinical features of cases (RA included in the study). Their role as a biomarker, as well as their potential to improve the tests currently available to detect ACPA will be explored.
This study will be conducted in Japan, South Korea and Taiwan to evaluate the optimal dosage of methotrexate (MTX) as an add-on therapy to adalimumab (ADA) in participants with rheumatoid arthritis (RA) who have not achieved remission by MTX monotherapy.
Boston Children's Hospital resources include SimulConsult which is a decision support tool available for use of BCH provider through the library portal. It is offered along other resources on that webpage (UpToDate, Micromedex, and VisualDx). See addendum 1. Recently, a pediatric rheumatology arm was added to the expertise of SimulConsult, guided by our co-PI, Dr. Robert Sundel. As this tool is being offered and used, the investigators would like to assess metric of performance of this tool in enhancing participant trainees knowledge about the work up of patients with a potential rheumatologic disorder. See also www.ncbi.nlm.gov/pubmed/27964737 The investigators are conducting a clinical research to assess improvement in the clinical performance of study participants evaluating patients with a potential rheumatologic disorder. The intervention involved in using a computerized decision support tool already available in the Boston Children's Hospital domain. The outcome will be comparing this performance to that of an attending physician as the gold standard. We will assess the study participants performance across two locations: Emergency Department and Rheumatology clinic. Care to patients remains unchanged, as the workup plan and care is provided by an attending across both domains. The investigators main hypothesis is that using a decision support tool will result in a higher agreement rate between study participants' differential diagnosis and work up plan compared with the gold standard (attending differential diagnosis and research plan).
The purpose of this study is to investigate the effects of a yoga program based on "Yoga in daily life system" in patients with rheumatoid arthritis. The investigators want to explore whether this program will improve health-related quality of life and psychological well-being in patients. In addition they want to explore its potential positive modulation of the immune system.
Background The risk for hospitalized infection (i.e. infection leading to hospitalization) in patients with inflammatory arthritis (rheumatoid arthritis (RA), psoriatic arthritis (PsA) or axial spondyloarthritis (axSpA) treated with biological drugs is known to be increased compared to the background population. In daily clinical practice, there is a need for a simple way to assess the absolute risk for hospitalized infection in individual patients based on easily available information such as age, diagnosis, functional status, comorbidities and medication. This risk estimate will be useful in clinical decision making e.g. when advising patients on whether or not to initiate biologic therapy or when advising patients on influenza or pneumococcal vaccination. Objectives The objectives are 1) to assess the risk for hospitalized infection (infection leading to hospitalization) in patients with inflammatory arthritis during 12 months of follow-up after initiating treatment with their first biological drug (bDMARD) with the risk in the general population, and 2) to develop a simple, clinically useful algorithm that allows prediction of the risk of hospitalized infection in individual patients. Methods Observational cohort study based on existing data in: The Danish Rheumatology Register (DANBIO), The Danish National Patient Register, The Danish National Prescription Register and The Danish Register of Causes of Death. All patients registered in DANBIO with RA, PsA or axSpA who initiated treatment with their first biological drug between January 1, 2006 and December 31, 2016 will be identified. Baseline predictors and outcomes (hospitalized infection or death) during 12 months of follow-up are obtained. Logistic regression analysis and 10-fold cross-validation will be used to develop and internally validate the prediction model.
This study will provide an educational intervention through means of a video to educate subjects on the risk of cardiovascular health on Rheumatoid arthritis.
To investigate the effect of CTLA4-Ig (abatacept) on phenotype, transcriptional profile, B cell receptor usage and functional parameters of circulating B cells expressing anticitrullinated protein antibodies (ACPA) in patients with early, methotrexate-naïve, ACPA positive rheumatoid arthritis.
Immune checkpoint inhibitors (ICIs) might have high grade immune-related adverse events (irAEs) from rhumatologic, endocrinologic, cardiac or other system origin. This study investigates reports of drug induced irAEs with treatment including anti-PD1, Anti-PDL-1, and Anti-CTLA4 classes using the World Health Organization (WHO) database VigiBase and the french database Base Nationale de PharmacoVigilance (BNPV).
