Filter by:The VaricElla zosteR VaccinE (VERVE) trial evaluates the safety and effectiveness of the Herpes zoster (HZ) vaccine for shingles, Zostavax, in patients over 50 years old with arthritis and other diseases who are using anti-tumor necrosis factor (TNF) therapy and who have not previously received the vaccine.
A clinical trial to assess the effect of celecoxib 200 milligrams (mg) once daily and 400 milligrams (mg) once daily compared to diclofenac three times daily in the treatment of Ankylosing Spondylitis (AS) for 12 weeks. This will be used to confirm the results of a prior 6 week trial.
The main objective is to identify in the candidate regions of differentially expressed genes by comparing the transcriptome of dendritic cells derived from circulating monocytes between cases and controls. Cases and family controls will be matched on the presence of HLA-B27 and depending on haplotype association studies to correlate the differences of gene expression and genetic variations with susceptibility to AS.
The purpose of this study is to study the benefits and risks of etanercept withdrawal in patients who have achieved a significant clinical response.
Patients receive study drug for one year (Part A). If, after the initial run-in phase, a sustained remission is reached they will be randomly split into one of three dose groups for another year (Part B). The maintenance of the sustained remission will be analyzed.
To identify new candidate genes and proteins that are differentially expressed in responders' vs non-responders to anti-TNF alpha therapy at the several time points the investigators will use the transcriptomic and proteomic analyses. Demonstrate a link between gene expression and protein markers regarding prediction to anti-TNF alpha therapy efficacy.
The family of inflammatory/autoimmune systemic diseases (IAD) form a continuum from pure inflammatory diseases to pure autoimmune diseases, encompassing a large panel of inflammatory diseases with some autoimmune components, and vice versa. Cross phenotyping of patients with IAD should be heuristic and help revise the nosography and the understanding of these diseases.
Ankylosing spondylitis is a chronic inflammatory condition that mostly affects the spine. This results in back pain and stiffness, and causes difficulty with daily activities. Physical activity and exercise are key components of the management of ankylosing spondylitis, however many adults with ankylosing spondylitis do not meet physical activity recommendations. This study aims to investigate the effects of a twelve week intervention designed to increase physical activity and exercise in adults with ankylosing spondylitis.
This was a prospective mono-country, multi-center study of the frequency of extra-axial manifestations (EAMs) in Ankylosing Spondylitis (AS) participants treated with adalimumab in routine clinical practice.
Ankylosing spondylitits (AS) is a chronic, systemic rheumatic disease primarily affecting spine and sacroiliac joints, which belongs to the group of conditions known as spondyloarthopathies and causes eventual fusion of the spine. Twin study in AS estimated a heritability of over 90%. HLA-B27 is regarded as the earlist and most important gene associated with AS heritability, and over 90% of AS patients carry HLA-B27 gene. HLA-B27 was highly polymorphic, and more than 89 subtypes of B27 gene have been found. Subtypes of HLA-B27 vary between different regions, and so on as the relationship between HLA-B27 subtypes and disease development among different races. Anti-TNF- agents were regarded as one milestone in recent years development on treatment of ankylosing spondylitis, and most patients showed significant improvement after anti-TNF- therapy. Yet part of patients still showed insufficient response. Our previous study suggested AS patients carrying different genotype of SNP in TNF gene had different response to anti-TNF- therapies. But more studies should be carried out to identified more gene polymorphisms associated with treatment response. In this study we designed a prospective, open-label trial to investigate the genetic difference beween AS patients with different response to anti-TNF- therapy. We plan to enroll 50-100 early AS patients which fulfill the 2009 ASAS axial spondyloarthritis classification criteria and have axial symptom for no more than 2 years. The patients must have high disease activity defined as BASDAI 4, and HLA-B27 test must be positive. The patients should be able to receive 24 weeks of etanercept treatment. And patients who have previous other anti-TNF- therapy and any contraindication of anti-TNF- therapy must be excluded. Other medicines should be stable for at least 4 weeks before etanercept treatment begins. For the clinic assessment, patients should fill in the AS questionaires and receive physical examination at each visit. ASAS20 is thought as the primary endpoint. For the genetic polymorphysm detection, we select 10-20 SNP in MHC region associated with AS and 5-10 HLA-B27 subtypes which have been worked over and have definite association with AS. At the first visit 4ml of anticoagulated blood was collected and DNA was extracted. Target SNPs are detected by PCR then direct sequencing. HLA-B27 subtypes are identified using PCRSSP methods. And the relationship between SNPs/HLA-B27 subtypes and different response to anti TNF- therapy is accessed using chi-square statistic process in SPSS software. In this study we plan to investigate the relationship between genetic background and the clinical response to anti-TNF- therapy in AS patients, which has been seldom reported before. Our group have been studying the disease-associated gene of AS for years, and got plenty of data and experience about genetic study of AS.
