The accumulative global burden of autoimmune and inflammatory rheumatic diseases is substantial. Studying the distribution of these conditions across various global regions and ethnic groups by means of geoepidemiology might readily provide epidemiological data and also advance our understanding of their genetic and environmental underpinnings. In order to depict the geoepidemiology of autoimmune and inflammatory rheumatic diseases, namely rheumatoid arthritis, juvenile rheumatoid arthritis, systemic lupus erythematosus, systemic sclerosis, ankylosing spondylitis and Sjögren's syndrome, we present a comprehensive collection of epidemiological reports from various world regions, including the prevalence of each of these conditions. The accumulated data show that the reviewed rheumatic diseases are global phenomena, and, with some variance, seem to be relatively evenly distributed. This finding is in contrast with the obviously uneven distribution of some major nonrheumatic autoimmune conditions. In addition, geoepidemiology demonstrates that ethnogenetic susceptibility interacts with lifestyle and environmental factors, which include socioeconomic status, infectious agents (triggering or protective agents), environmental pollutants, and vitamin D (dependent on sunlight exposure), in determining the risk of developing rheumatic autoimmunity. © 2010 Macmillan Publishers Limited.

Paraneoplastic symptoms, caused by a malignancy, but not directly related to invasion by the tumor or its metastases, are the result of a wide variety of tumor-derived biologic mediators like hormones, peptides, antibodies, cytotoxic lymphocytes, autocrine and paracrine mediators. Systemic inflammatory rheumatic diseases, such as rheumatoid arthritis, systemic lupus erythematosus, scleroderma or dermatomyositis, may increase the risk for the development of malignancies, predominantly lymphoproliferative disorders. Immunosuppressive drugs and biological agents may also be carcinogenic. However, sustained inflammatory activity seems to be the primary risk factor for malignancies in autoimmune diseases. Tumor-associated antigens may be produced by inflammatory cells and their production may be increased in rheumatoid arthritis and other autoimmune diseases. Copyright © 2010 S. Karger AG, Basel.

Objectives: The Dead Sea, the deepest and most saline lake on earth, has been known from biblical times for its healing properties. The aim of this systematic review was to present critically the level of evidence for the claims of therapeutic effects of Dead Sea treatments in several rheumatologic diseases and psoriasis as well as to review these treatments' safety. Methods: All articles cited in MEDLINE under the query, "Dead Sea," were reviewed. Results: We found bona fide evidence that Dead Sea treatments are especially effective in psoriasis due to both the special characteristics of solar ultraviolet radiation in the Dead Sea and the Dead Sea water balneotherapy. Dead Sea mud and Dead Sea balneotherapy have been found to be beneficial in rheumatologic diseases, including rheumatoid arthritis, psoriatic arthritis, ankylosing spondylitis, and knee osteoarthritis. In the safety analysis, we found no evidence for an increase in skin neoplasia, although skin actinic damage seems to be increased in patients treated in the Dead Sea. Dead Sea treatments do not lead to worsening of blood pressure. Substantial ingestion of Dead Sea water (generally in unusual near-drowning cases) is toxic and can result in cardiac rhythm disturbances because of electrolyte concentration abnormalities. Laboratory analysis of Dead Sea mud did not reveal mineral concentrations that could represent a health concern for their intended use. Conclusions: Dead Sea treatments are beneficial in several rheumatologic diseases and psoriasis and have a good safety profile. © 2012 Elsevier Inc.

Neuromyelitis optica (NMO or Devic's syndrome) is a rare autoimmune disease, previously considered a multiple sclerosis variant. The most important laboratory and clinical features are optic myelitis and transverse myelitis, associated with neuromyelitis optica-IgG antibody (NMO-IgG) positivity. Subsequent to this immunological test being available, different groups have described the not-so-rare comorbidity of neuromyelitis optica with other systemic autoimmune diseases, systemic lupus erythematosus with secondary anti-phospholipid syndrome (APS) in particular. We describe a patient meeting both the classification criteria for primary APS and the new diagnostic criteria for neuromyelitis optica. It's important to diagnose NMO syndrome as both optic neuritis and transverse myelitis were also considered neurological complications of antiphospholipid syndrome. NMO-IgG is a new and fundamental test to decide if immunosuppressant therapy is warranted for such patients. © The Author(s), 2010.

Autoimmunity plays a role in the pathogenesis of numerous cardiac diseases such as dilated cardiomyopathy (DCM), myocarditis, rheumatic fever and atherosclerosis. An autoimmune response may appear following myocardial injury and exposure to self-antigens. Anti-heart autoantibodies have been identified in patients with heart disease and in low titres of healthy individuals. Troponin is the preferred marker in detecting acute coronary syndrome. In recent years, anti-troponin autoantibodies were identified in patients with DCM and ischaemic cardiomyopathy. The presence of anti-troponin autoantibodies in the serum may cause a false-negative evaluation of troponin levels and delay treatment of acute coronary syndrome. The role of anti-troponin autoantibodies in humans and their possible involvement in the pathogenesis of heart disease remains controversial. Previous studies have demonstrated that anti-troponin autoantibodies can cause cardiac dysfunction in animal models. This paper reviews current knowledge on anti-troponin autoantibodies. Future research should focus on the pathogenic role of anti-troponin autoantibodies and reactive T cells and the possible benefits of targeted therapy in acute coronary syndrome, post-myocardial infarction, myocarditis, DCM and heart failure.
