An investigation into the relationship between anti-Helicobacter pylori and anti-Saccharomyces cerevisiae antibodies in patients with axial spondyloarthritis and Crohn disease.

Spondyloarthritis (SpA) is a musculoskeletal inflammatory disease linked with immune responses to intestinal microbiota, and subclinical intestinal ulcerations that are closely related to inflammatory bowel diseases. Helicobacter pylori is a common cause of gastroduodenal ulceration, and anti-Saccharomyces cerevisiae antibodies (ASCA) are associated with intestinal inflammation in both Crohn disease (CD) and SpA. We investigated the relationship between H.

Update on etiopathogenesis of systemic sclerosis.

Systemic Sclerosis (SSc) is an autoimmune disease of multifactorial etiology, triggered by a combination of genetic and environmental factors. Its varied clinical expression results from the complex physiopathogenic interaction of three main elements: proliferative vasculopathy, immune dysregulation and abnormal deposition and remodeling of the extracellular matrix (ECM), of which the characteristic disease fibrosis is the result. Early physiopathogenic events appear to be endothelial injury and imbalance in vascular repair with the activation of endothelial cells, the immune system and platelets, with the release of multiple mediators such as TH2 proinflammatory cytokines and growth factors, triggering a sequence of simultaneous or cascading events that involve several intracellular signaling pathways.

Subclinical atherosclerosis in ankylosing spondylitis: is there a role for inflammation?

Objectives: To evaluate the prevalence of subclinical atherosclerosis in patients with ankylosing spondylitis (AS) in comparison to controls with similar cardiovascular risk factors.

Methods: Forty-two consecutive patients with AS and 42 controls matched for age (43.3 ± 11.

Lack of association between interleukin-18 polymorphisms and rheumatoid arthritis.

Objective: To assess the association of the polymorphisms of the interleukin-18 (IL-18) gene with rheumatoid arthritis (RA) and with risk factors for cardiovascular diseases (CVD).

Methods: This sample comprised 97 patients with RA and 151 healthy controls. In the patients, risk factors for CVD were analyzed, such as cholesterol levels, arterial hypertension, smoking habit, C-reactive protein (CRP) level, and rheumatoid factor.

Neuro-Behçet's disease, its mimickers and anti-TNF therapy: a case-based review.

When the central nervous system is the primary affected site in an initial attack of Behçet's disease (BD), the differential diagnosis is particularly challenging. Because the specificity of immunobiologic therapy is growing, the specific diagnosis may impact the chosen therapy. For instance, anti-tumour necrosis factor agents are efficacious in BD but may be harmful in multiple sclerosis or systemic lupus erythematosus.

Thoracic myelopathy due to calcification of the ligamentum flavum with hyperproteinorachia and responsive to steroid therapy: case report.

Calcification and ossification of the ligamentum flavum or of the posterior longitudinal ligament are causes of compressive myelopathy, more frequent in the lower thoracic levels, and extremely rare in Western populations. Surgical decompression is the only therapy, but the disease is usually progressive, and its recurrence after surgery is common. Inflammatory mediators might play a role in the progression of compressive myelopathy, but, to our knowledge, the therapeutic approach involving anti-inflammatory agents has never been tried before.

Tumor markers are elevated in patients with rheumatoid arthritis and do not indicate presence of cancer.

Aim: To investigate serum levels of tumor markers in patients with rheumatoid arthritis (RA) and their association with disease activity or the presence of cancer.

Method: We performed an observational cohort study including 100 patients with RA and control subjects. Serum levels of tumor markers carcinoembryonic antigen (CEA), cancer antigen (CA) 125, CA 19-9 and CA 15-3 were evaluated along with clinical and laboratorial RA data.

Mycophenolate mofetil in primary Sjögren's syndrome: a treatment option for agranulocytosis.

The Sjögren's syndrome (SS) is an autoimmune disease characterized by a lymphocytic infiltration of salivary and lacrimal glands. Hematological manifestations of primary SS (pSS) usually consist of mild anemia, thrombocytopenia, moderate neutropenia, and lymphopenia. Agranulocytosis is rarely reported and usually responds to immunosuppression.

Musculoskeletal system assessment in an emergency room.

Objective: Musculoskeletal conditions have an enormous and growing impact worldwide. In spite of that, some clinicians are not confident in their own musculoskeletal examination skills. This study aimed to evaluate the prevalence of musculoskeletal symptoms in an emergency room, and the frequency of musculoskeletal physical examination description on those cases.

Liver toxicity is rare in rheumatoid arthritis patients using combination therapy with leflunomide and methotrexate.

Objective: Some studies have reported that adding leflunomide (LEF) to the treatment of rheumatoid arthritis (RA) in patients who do not respond to methotrexate (MTX) improved efficacy but increased the risk of liver toxicity. This study aimed at assessing the incidence of liver toxicity in patients with active RA using the LEF and MTX combination therapy in comparison with that of patients on MTX monotherapy.

Methods: Between February and September 2009, 97 consecutive patients followed up at the University Hospital of the Universidade Federal de Santa Catarina, Brazil, were enrolled.

Potential drug interactions in patients with rheumatoid arthritis.

Introduction: The term polypharmacy, meaning the concomitant use of multiple medications by one individual, has been widely reported in institutionalized or elderly patients. It can, however, occur in patients with chronic diseases, such as rheumatoid arthritis (RA).

Objective: To quantify polypharmacy in a group of RA patients and to assess the risk of potential undesirable interactions between medications used for managing RA and those used for non-chronic diseases.
