Active clinical trials for "Spondylitis"

Cross sectional study assessing food practices and beliefs in RA, AS and DA (digital arthritis)

The aim of this study is to evaluate the relationship between decrease in work productivity and social activities in patients with Ankylosing Spondylitis (AS) with disease activity, depression and quality of life together with demographic data.

This was a multicenter, retrospective, and non-interventional study using secondary data captured in the Electronic Health Records (EHRs). The extraction of the data captured in the EHRs was performed with EHRead® by SAVANA, an innovating data-driven system based on Natural Language Processing (NLP) and big data analytics. Data was extracted and analyzed at Index Date, Follow Up, or as specified for each variable.

This study aims to evaluate the impact of AbbVie Care 2.0 on adalimumab's compliance, patient reported outcomes and utilization of health resources over 12 months.

The objective of this study is to access retention rate, persistence and adherence in population of spondylarthritis (SpA) (ankylosing spondylitis (AS) and psoriatic arthritis (PsA)) participants treated with adalimumab in routine clinical settings in the Russian Federation.

This is a retrospective and prospective designed study, included hospitals are 1:1 assigned into two groups: ①Interventional hospital, which will receive 3-month medical education; ②Non-interventional hospital, which will not receive 3-month medical education. During 1 month before education, all the electronic records of outpatients and inpatients who visit the included rheumatologists will be collected and the data of test and evaluation results of spondyloarthritis (SpA) patients diagnosed according to new Assessment of Spondylo-Arthritis International Society (ASAS) criteria will be collected from outpatient electronic records and inpatients medical charts; in the 3 months after education, the same data will be collected and compared with the data before education, and the impact of medical education on physician behaviour will be analyzed. Meanwhile, the understanding and acceptance level will be evaluated by the questionnaire, the differences before and after education and the impact of education on physician cognition will be evaluated.

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.

Chronic joint complaints are prevalent in clinical practice. If chronic arthritis such as rheumatoid arthritis (RA) or ankylosing spondylitis (AS) is not adequately controlled, it can not only affect patient's working ability but also produce indirect cost in patient's family. Quality of life will also be affected. Health-related quality of life issues are assuming increasing importance in chronic rheumatic diseases. However, studies on quality of life in rheumatic patients are limited. Factors related to quality of life are not clear. Application of quality of life measurement for improving clinical care of RA and AS patients is still difficult. The objective of this study was to evaluation the validity of EQ-5D life quality measurement in chronic arthritis patients in Taiwan. Factors associated with life quality will be addressed. This will also provide useful information for public health policy making.

Observe in real life adherence therapy and time to switch in ankylosing spondylitis patients with predominant assial involvement with 4 anti-TNF.

The study investigates different criteria for remission based on MRI and circulating biomarkers for inflammation, cartilage, connective tissue and bone turnover in patients with axial spondyloarthritis treated with Golimumab. Furthermore, the study also investigates factors that affect disease activity, function and participation by use of different questionnaires.
