Spondyloarthropaties

Psoriatic arthritis (PsA) is a heterogeneous multifaceted inflammatory artropathy, associated or not with psoriasis, part of the spondyloarthropaties group. Beyond articular and skin manifestations, patients with psoriatic disease are prone to associated comorbidities, including cardiovascular disease (CVD), obesity and metabolic syndrome, diabetes, or fatty liver disease; in order to improve the prognosis and the quality of life for these patients, it is mandatory to prevent, identify and properly manage any of the comorbidities...

Tumor necrosis factor inhibitors (anti-TNF) have emerged as an effective treatment in noninfectious uveitis (NIU). Anti-TNF may increase the predisposition to infectious disease as tuberculosis (TB). TB-related uveitis in the context of an uveitogenic concurrent systemic immune-mediated disease under anti-TNF treatment remain a diagnostic challenge, deserving special focus on this rare context. Retrospective chart review of patients on anti-TNF drugs for systemic immune-mediated diseases that developed a multicentric microbiologically confirmed active TB with concurrent intraocular involvement...

Osteochondroprogenitors are crucial for embryonic bone development and postnatal processes such as bone repair in response to fracture injury, and their dysfunction may contribute to insufficient repair of structural damage in inflammatory arthritides. In the fracture healing, the early inflammatory phase is crucial for normal callus development and new bone formation. This process involves a complex interplay of many molecules and cell types, responsible for recruitment, expansion and differentiation of osteochondroprogenitor populations...

The neurologic complications of rheumatic disease are highly variable and their manifestations are linked to the pathogenesis and clinical phenotype of the specific rheumatologic syndrome. In active rheumatoid arthritis (RA), the peripheral nervous system is most commonly involved and mononeuritis multiplex, nerve entrapment and vascultitic sensorimotor neuropathy are not uncommon. Central nervous system complications such as pachymeningitis and cerebral vasculitis are rare. TNF blockade therapy of RA is rarely associated with demyelinating syndromes...

Cardiovascular system involvement is a frequent complication of autoimmune diseases (AD) such as systemic lupus erythematosus, scleroderma, rheumatoid arthritis, spondyloarthropaties or psoriatic arthritis. The most common forms of such involvement are pericarditis, myocarditis, accelerated atherosclerosis resulting in myocardial infarction or stroke, arrhythmias, conduction abnormalities or congestive heart failure. Some of these manifestations may be dramatic in their course and ultimately fatal. The treatment of AD may further affect the cardiovascular system and result in a lower quality of life, higher mortality and increased cost of healthcare...

Rheumatic autoimmune diseases have been associated with accelerated atherosclerosis and various types of vasculopathies. Atherosclerosis is an inflammatory condition which starts as a "response to injury" favoring endothelial dysfunction which is associated with increased expression of adhesion molecules, pro-inflammatory cytokines, pro-thrombotic factors, oxidative stress upregulation and abnormal vascular tone modulation. Endothelial dysfunction in rheumatic autoimmune diseases involves innate immune responses, including macrophages and dendritic cells expression of scavenger and toll-like receptors for modified or native LDL as well as neutrophil and complement activation, and dysregulation of adaptive immune responses, including proliferation of autoreactive T-helper-1 lymphocytes and defective function of dendritic and regulatory T cells...

OBJECTIVE: To describe the main demographic and clinical features of patients with spondyloarthropaties in Spain. PATIENTS AND METHODS: Review of randomized clinical charts of patients with spondyloarthropaties with at least one visit to the rheumatologist in the previous two years. Information was collected on demographic and clinical data (duration of illness, diagnostic category, disease activity, extrarticular manifestations, comorbidity and work disability)...

An increasing number of women have been diagnosed with spondyloarthritis (SpA) in recent decades. While a few studies have analyzed gender as a prognostic factor of the disease, no studies have addressed this matter with a large number of patients in South America, which is a peculiar region due to its genetic heterogeneity. The aim of the present study was to analyze the influence of gender on disease patterns in a large cohort of Brazilian patients with SpA. A prospective study was carried out involving 1,505 patients [1,090 males (72...

Epidemiologic, clinical, and genetic studies provide grounds for differentiation of juvenile spondyloarthropathies from other rheumatic diseases. The prevalence of spondyloarthropathies among whites is estimated at 0.7 to 1.2% and the female-to-male ratio is 1:2.5. The current classification of clinically defined and undefined forms of juvenile spondyloarthropathies is presented together with their diagnostic criteria and treatment.

Transgenic rats with high expression of HLA-B27 and human β(2) -microglobulin (B27TR) develop a multisystem inflammatory disease resembling human inflammatory bowel disease (IBD) and spondyloarthropaties (SpA). Tumour necrosis factor α (TNF-α) has a crucial role in sustaining chronic inflammation in the gut and joints. The aim of this work was to evaluate whether TNF-α blockade could prevent or reduce the inflammation of peripheral joints in B27TR. A first group of 9-week-old B27TR received an anti-TNF-α monoclonal antibody (mAb) or an isotypic IgG2a,k up to the age of 18 weeks...

OBJECTIVE: To retrospectively evaluate the role of the various imaging techniques in the study of the sternocostoclavicular joint, in patients with spondyloarthropathies and other rheumatic conditions and to assess potential pitfalls in the radiological diagnosis. SUBJECTS AND METHODS: Thirty patients, 11 male and 19 female, mean age 45 years, with involvement of the sternocostoclavicular joint as part of rheumatologic disorders (psoriatic arthritis, ankylosing spondylitis, Tietze syndrome, SAPHO syndrome, and condensing osteitis of the clavicle) were studied...

Ocular inflammation is a common clinical manifestation related to several autoimmune systemic disorders, specially spondyloarthropaties. In this group, there are different clinical diseases that are related to special uveitic patterns. Several discriminative patterns have been defined that closely link uveitis with certain systemic or ophthalmic diseases. Unilateral recurrent anterior acute uveitis is the most frequent form of uveitis related to spondyloarthropaties, and is sometimes the initial manifestation of an undiagnosed spondyloarthropaty...

OBJECTIVES: The pathogenesis of seronegative spondyloarthropathies is still unknown. A microbial etiology has been suggested. The aim of the study was to analyze the antibodies against Klebsiella O-antigens in serum of patients with seronegative spondyloarthropathies. METHODS: 30 patients with seronegative spondyloarthropathies, 20 with rheumatoid arthritis and 20 healthy volunteers were included in the study. The serum antibodies against Klebsiella O1 and O3 antigens were analyzed by enzyme-linked immunosorbent assay (ELISA)...

Antinuclear antibodies (ANAs) have become routine laboratory parameters in clinical hospitals. However, ANA testing by indirect immunofluorescence (IIF) assays is not an automated laboratory test. Efforts are being made to develop easy and semi- or automated methods to screen for ANAs. We evaluated the clinical performance of a new ELISA developed to screen for connective tissue disease related ANAs. The presence of serum ANA was studied with a commercial ELISA (Varelisa ANA CTD Screen) in 472 patients (202 SLE, 41 Sjögren syndrome, 11 CREST, 59 rheumatoid arthritis, 30 seronegative spondyloarthropaties, 77 inflammatory bowel disease, 13 reactive arthritis, 11 giant cell arteritis, 28 ankylosing spondilitis)...

Pregnancy is a phenomenon that is not totally understood, based on the complex molecular interactions between the mother and the embrio. Once the fecundation is completed the fetus starts to fight for survival. The first challenge is the implantation process and the second one is the interaction with the maternal immune system. This review discusses how the fetus avoids the immune system rejection, and the mechanisms that the maternal immune system adapts in order to be fit for a successful pregnancy. Also, we focus in this paper on the effects of pregnancy in rheumatic diseases, because the myriad clinical outcomes of the disease itself and the obstetric complications dependent of the disease implicated, as for example in rheumatoid arthritis (RA), systemic lupus erythematosus (SLE), spondyloarthropaties and antiphospholipid syndrome (APS)...

Spondyloarthropathy is a group of chronic autoimmune disorders including ankylosing spondylitis, reactive arthritis, psoriatic arthritis, arthritis associated with inflammatory bowel disease, acute anterior uveitis and undifferentiated spondyloarthropathies. The spondyloarthropathies share common clinical, radiological, and genetic features that are clearly distinct from other inflammatory rheumatic diseases. The major goal in the management of patients with rheumatic disorders is to control or cure the disease and to preserve and control function and health status...
