Axial Spondylarthropathy

OBJECTIVE: To provide evidence-based recommendations for the treatment of patients with ankylosing spondylitis (AS) and nonradiographic axial spondyloarthritis (SpA). METHODS: A core group led the development of the recommendations, starting with the treatment questions. A literature review group conducted systematic literature reviews of studies that addressed 57 specific treatment questions, based on searches conducted in OVID Medline (1946-2014), PubMed (1966-2014), and the Cochrane Library...

OBJECTIVE: To determine the frequency and risk factors of low bone mineral density in patients with spondyloarthropathies. METHODS: The cross-sectional study was conducted at the Rheumatology Department of a tertiary care hospital in Karachi between June and November 2014, and comprised spondyloarthritis patients whose bone mineral density of lumbar spine and hips was measured using dual energy X-ray absorptiometry scan. Variables like disease duration, diagnosis, human leukocyte antigen subtype B27, erythrocyte sedimentation rate, C-reactive protein, Bath ankylosing spondylitis disease activity Index, Bath ankylosing spondylitis functional index, Bath ankylosing spondylitis metrology index were measured along with outcomes, differentiating between osteopenia and/or osteoporosis...

BACKGROUND: Musculoskeletal symptoms are the most common extra-intestinal manifestation associated with inflammatory bowel disease (IBD). Spondyloarthritis (SpA) is an umbrella term applied to a group of rheumatic diseases with some features in common and others distinct from other inflammatory arthritides. AIM: To determine self-reported prevalence of SpA associated musculoskeletal manifestations in an IBD cohort on tumour necrosis factor (TNF) inhibitors using a questionnaire incorporating Assessment of SpondyloArthritis International Society (ASAS) criteria...

BACKGROUND: The reactive form of spondyloarthropathy appears inducible by exposure to agents of infectious diarrhea, but do those organisms represent the tip of the iceberg, as indicated by renewed interest in gastrointestinal flora? Prevalence of spondyloarthropathy (20% of chimpanzees [Pan] and 28% of gorillas) is independent of subspecies and species, respectively. However, there are major differences in arthritis patterns, a characteristic shared with humans. OBJECTIVES: Do patterns of arthritis correlate with gastrointestinal flora? Could such associated modifications be in the form of disease induction or represent protective effectors (at least against the extent of peripheral arthritis)? METHODS: The skeletons of 2 chimpanzee subspecies (79 Pan troglodytes troglodytes and 26 Pan troglodytes schweinfurthii) and 2 gorilla species (99 Gorilla gorilla and 38 Gorilla beringei) adults were examined, and arthritis pattern noted...

OBJECTIVE: To evaluate the effect of tumor necrosis factor (TNF) inhibitors on nonsteroidal antiinflammatory drug (NSAID) intake in a cohort of patients with early axial spondyloarthritis (SpA) over the first 2 years of followup. METHODS: The Devenir des Spondylarthropathies Indifférenciées Récentes (DESIR) cohort is a prospective, multicenter, observational study cohort of patients with early inflammatory back pain. The management and treatment of these patients were decided by their treating rheumatologists...

OBJECTIVE: To investigate the clinical course of disease over 2 years in patients with nonradiographic axial spondylarthritis (SpA) and patients with ankylosing spondylitis (AS). METHODS: The study group comprised 303 patients with axial SpA (158 patients with AS and a symptom duration of ≤10 years and 145 patients with nonradiographic axial SpA and a symptom duration of ≤5 years) who did not receive tumor necrosis factor (TNF) blockers during 2 years of followup...

The aim of this work was to develop a consensual recommendation under the auspices of the Assessment of SpondyloArthritis international Society (ASAS) for early referral of patients with a suspicion of axial spondyloarthritis by non-rheumatologists. The development of a referral recommendation consisted of four phases: (1) systematic literature review, (2) the first Delphi round aiming at identification of unmet needs and development of a candidate list of referral parameters, (3) the second Delphi round aiming at identification of the most useful combination of referral parameters and (4) final discussion and formal endorsement by ASAS membership...

A variety of cardiovascular clinical manifestations have been described in patients with spondyloarthritis, especially in well-established ankylosing spondylitis. These include both structural heart disease, conduction defects and ischemic heart disease. The true prevalence of cardiovascular involvement in patients with axial spondyloarthritis, including non-radiographic disease needs to be further defined.

OBJECTIVE: Axial spondyloarthritis (AxSpA) represents a group of inflammatory axial diseases that share common clinical and histopathological manifestations. Ankylosing spondylitis (AS) is the best characterised subset of AxSpA, and its genetic basis has been extensively investigated. Given that genome-wide association studies account for only 25% of AS heritability, the objective of this study was to discover rare, highly penetrant genetic variants in AxSpA pathogenesis using a well-characterised, multigenerational family...

Although axial spondyloarthritis (axSpA) is as prevalent as rheumatoid arthritis, it is commonly under recognized due to variety of reasons. AxSpA contributes to significant loss of function and disability among young adults. With the availability of newer assessment methods and effective therapeutic agents, early diagnosis and appropriate treatment are possible. As mechanical back pain is widely prevalent in general population, selection of patients with high likelihood of having axSpA and referral to rheumatologists is very important to allow prompt diagnosis and management of axSpA yet avoid improper utilization of resources...

Th17 cells are a discrete subset of T cell subpopulation, which produce IL-17 and certain other pro-inflammatory cytokines. A regulatory role of Th17 cells have been proposed in several autoimmune diseases including psoriasis, psoriatic arthritis (PsA), ankylosing spondylitis (AS), rheumatoid arthritis, inflammatory bowel disease, systemic lupus erythematosus, and multiple sclerosis. Psoriatic disease is an autoimmune disease which mainly involves skin and joints. Until recently, psoriasis and PsA were thought to be Th1 mediated disease, but after the discovery of IL-17 and IL-17 knockout animal studies as well as human experimental data indicate a crucial role of the Th17 cells in the pathogenesis of psoriasis and PsA...

With the growing awareness of the impact of chronic back pain and axial spondyloarthritis and recent breakthroughs in genetics and the development of novel treatments which may impact best on early disease, the need for markers that can facilitate early diagnosis and profiling those individuals at the highest risk for a bad outcome has never been greater. The genetic basis of ankylosing spondylitis has been considerably advanced, and HLA-B27 testing has a role in the diagnosis. Knowledge is still incomplete of the rest of the genetic contribution to disease susceptibility, and it is likely premature to use extensive genetic testing (other than HLA-B27) for diagnosis...

OBJECTIVES: Except for traumatic and iatrogenic causes, Achilles tendinitis (AT) is mostly encountered in the context of inflammatory rheumatic diseases. This study aimed to describe AT in systemic lupus erythematosus (SLE). PATIENTS AND METHODS: Among 158 SLE patients who fulfilled the SLE criteria of the ACR classification followed between 1980 and 2013, we selected those who experienced at least one episode of AT not caused by traumatic or toxicity factors. RESULTS: Eight patients (one male, seven females), median age 52 years (range: 35-68), presented with 11 episodes of AT within an average of 10...

OBJECTIVE: To investigate the possible occurrence of early thymic failure and premature senescence of naïve and memory T-cells in patients with axial spondyloarthritis (aSpA). METHODS: Prospective, cross-sectional study of consecutive patients with aSpA (n=51), rheumatoid arthritis (RA, n=51) and healthy controls (HCs, n=50). Demographic, clinical and laboratory parameters were collected in all patients and we isolated naïve (CD45RA(+)) and memory (CD45RO(+)) CD4(+) and CD8(+) T-cell subsets by MACS technology...

OBJECTIVES: To investigate the impact of smoking on the response to treatment with a first tumour necrosis factor inhibitor (TNFi) in patients with axial spondyloarthritis (axSpA) in a real-life cohort. METHODS: Patients fulfilling the Assessment of SpondyloArthritis international Society (ASAS) classification criteria for axSpA in the Swiss Clinical Quality Management Cohort were included in this study. The potential association between smoking status and differential response to TNFi in terms of the Bath Ankylosing Spondylitis Disease Activity Index (BASDAI) and the Ankylosing Spondylitis Disease Activity Score (ASDAS) was analysed using multiple adjusted longitudinal mixed effect models...

In recent years the early identification of axial spondyloarthritis has become a high priority area of research. Evidence that therapy may slow radiographic progression of disease has heightened the importance of recognition of early disease. However, the concept of early axial spondyloarthritis and natural history of early disease are not fully understood. Future strategies to detect early and preclinical disease may incorporate clinical information, radiographic, serologic, and genetic testing. The risks and benefits of screening and early identification of disease need careful consideration...

A strong connection between spondylarthropathies and inflammatory bowel diseases (IBD) is well established. About 10-15% of IBD are associated with different forms of spondylarthritis. Arthritis can be manifested as axial, peripheral form or both. The primary functions of the gastrointestinal tract are digestion and absorption of nutrients, electrocytes and maintenance of water homoeostasis. The anatomic and functional lesions could lead to the development of IBD based on molecular mimicry and bystander effects...

Because psoriatic arthritis (PsA) is an inflammatory disease of joints, serum soluble biomarkers specific for chronic joint and bone inflammation may predict future disease severity and response to therapy, thereby informing stratified medicine approaches. The objectives of our systematic review were to determine whether serum soluble bone and cartilage turnover biomarkers are (1) associated with PsA or psoriatic spondyloarthropathy; and (2) associated with disease activity, disease severity, or clinical phenotype...

Physical activity (PA) is associated with numerous health-related benefits among adults with chronic diseases and the general population. As the benefits are dose-dependent, this review aims to establish the PA levels of adults with spondyloarthritis and to compare these to the general population. Electronic databases (Cochrane Central Register of Controlled Trials, EMBASE, MEDLINE/PubMed, PEDro, AMED, CINAHL) were systematically searched from inception to May 2014 using medical subject headings and keywords...
