The chronic, destructive autoimmune arthritis in SKG mice, which closely resembles human rheumatoid arthritis, is the result of self-reactive T cells escaping thymic deletion. Since the inhibitory receptor LIR-1 is up-regulated on auto-reactive T cells in human rheumatoid arthritis, the role of its murine ortholog PIR-B was investigated. Peripheral CD4(+) T cells from SKG mice were found to frequently express PIR-B, and this population produces more frequently IL-17 upon in vitro stimulation compared to PIR-B(-) cells...

Lung ailments in rheumatic diseases present unique challenges for diagnosis and management and are a source of significant morbidity and mortality for patients. Unlike the idiopathic interstitial pneumonias, patients with rheumatic diseases experience lung disease in the context of a systemic disease that may make it more difficult to recognize and that may present greater risks with treatment. Despite recent advances in our awareness of these diseases, there is still a significant lack of understanding of natural history to elucidate which patients will have disease that is progressive and thus warrants treatment...

The incorporation of a single β-amino acid moiety in a highly amyloidogenic peptide sequence resulted in the complete inhibition of amyloid fibril formation. The Boc-l-Phe-l-Leu-OMe sequence 1, which has sequence identity with the N-terminal AS(6-7) of the non-immunoglobulin amyloid fibril protein AS, which is responsible for rheumatoid arthritis, self-associates to produce fibrils. The d-Phe analogue peptide 2 shows an elongated ribbon-like morphology. However, the 2-aminomethyl-3-(4-methoxy-phenyl)-propionic acid containing analogue peptide 3 exhibits a polydisperse microsphere morphology...

Tertiary lymphoid organs are found at sites of chronic inflammation in autoimmune diseases such as systemic lupus erythematosus and rheumatoid arthritis. These organized accumulations of T and B cells resemble secondary lymphoid organs and generate autoreactive effector cells. However, whether they contribute to disease pathogenesis or have protective functions is unclear. Here, we discuss how tertiary lymphoid organs can generate potentially pathogenic cells but may also limit the extent of the response and damage in autoimmune disease...

Angioimmunoblastic T-cell lymphoma (AITL) is a rare subtype of peripheral T-cell lymphoma (PTCL). AITL typically presents with lymphadenopathy, fever, rash, hepatosplenomegaly, and rarely polyarthritis. We report the case of a 50-year-old female who presented with lymphadenopathy, rash, and symmetric polyarthritis. She was later diagnosed with AITL and was treated with chemotherapy with resolution of arthritis. AITL should be suspected in paitents presenting with rheumatoid-like arthritis and diffuse lymphadenopathy...

Th17 cells are an important therapeutic target in autoimmunity. However, it is known that Th17 cells exhibit considerable plasticity, particularly at sites of autoimmune inflammation. Th17 cells can switch to become ex-Th17 cells that no longer produce IL-17 but produce IFN-γ. These ex-Th17 cells are also called nonclassical Th1 cells because of their ability to produce IFN-γ, similar to Th1 cells; however, it is unclear whether they resemble Th1 or Th17 cells in terms of their function and regulation, and whether they have a pathogenic role in autoimmunity...

To date, rheumatoid arthritis (RA) remains a debilitating, life-threatening disease. One major concern is morning symptoms (MS), as they considerably impair the patients' quality of life and ability to work. MS change in a circadian fashion, resembling the fluctuations of inflammatory cytokines such as interleukin-6, whose levels are higher in RA patients compared to healthy donors. Conversely, serum levels of the potent anti-inflammatory glucocorticoid cortisol are similar to that of healthy subjects, suggesting an imbalance that sustains a pro-inflammatory state...

BACKGROUND: To examine the site-specific cancer mortality among deaths registered with Parkinson's disease (PD) and multiple sclerosis (MS). We focused on the patterns related to the most frequent cancers. METHODS: We analyzed Swiss mortality data over a 39-year period (1969-2007), using a statistical approach applicable to unique daabases, i.e. when no linkage with morbidity databases or disease registries is possible. It was based on a case-control design with bootstrapping to derive standardized mortality ratios (SMR)...

BACKGROUND: Operative treatment of chondrocalcinosis (calcium pyrophosphate dihydrate deposition disease=CPPD disease) of the wrist is hardly ever mentioned in the literature. Since the chronic, recurrent type of this disease resembles rheumatoid arthritis (RA) as well as osteoarthritis, the author has performed arthroscopic synovectomy of the wrist, which achieves excellent results in RA und offers high patient comfort as an atraumatic procedure with low morbidity. This article presents the experience made with arthroscopic synovectomy in CPPD disease of the wrist...

Therapeutic efficiency of NSAID is handicapped by ongoing discussion of cardiovascular (CV) safety. Areas covered: We update meta-analyses on NSAIDs in patients with and without cardiovascular (CV) diseases and analyse the association between NSAIDs and cardiovascular events in patients with inflammation. We demonstrate the substantial influence of an indication bias and confounding, which falsely increase the CV risk. We demonstrate protective cardiovascular effects of NSAIDs due to their anti-inflammatory activity, in particular in patients with rheumatoid arthritis, osteoarthritis or inflammatory pain...

Rheumatoid arthritis is a chronic autoimmune pathology characterized by the proliferation and inflammation of the synovium. Boron neutron capture synovectomy (BNCS), a binary treatment modality that combines the preferential incorporation of boron carriers to target tissue and neutron irradiation, was proposed to treat the pathological synovium in arthritis. In a previous biodistribution study, we showed the incorporation of therapeutically useful boron concentrations to the pathological synovium in a model of antigen-induced arthritis (AIA) in rabbits, employing two boron compounds approved for their use in humans, i...

In this MiniReview, we summarize the body of knowledge on the delayed-type hypersensitivity arthritis (DTHA) model, a recently developed arthritis model with 100% incidence, low variation and synchronized onset in C57BL/6 (B6) mice, and compare it to other murine arthritis models. It is desirable to have robust arthritis models in B6 mice, as many transgene strains are bred on this background. However, several of the most widely used mouse model of arthritis cannot be induced in B6 mice without the drawback of lower incidence, reduced severity and higher variation, if at all...

Spondyloepiphyseal dysplasia (SED) tarda is an inherited skeletal arthropathy. Because SED tarda involves the joints and resemble the clinical findings of chronic arthropathies, this disease is frequently misdiagnosed as juvenile idiopathic arthritis (JIA). We report here on three patients (father and his two daughters) in one family with SED tarda. All patients had back pain and polyarthralgia. Their radiographs revealed typical changes for SED tarda including platyspondyly and dysplastic bone changes. This rare disease has major clinical importance in that it is similar with JIA or rheumatoid arthritis...

Coronary artery disease is a common disease that seriously threaten the health of more than 150 million people per year. Atherosclerosis is considered to be the main cause of coronary artery disease which begins with damage or injury to the inner layer of a coronary artery, sometimes as early as childhood. The damage may be caused by various factors, including: smoking, high blood pressure, hypercholesterolemia, sedentary lifestyle, diabetes and insulin resistance. Once a coronary artery disease has developed, all patients need to be treated with long term standard treatment, including heart-healthy lifestyle changes, medicines, and medical procedures or surgery...

Rat bite fever is rare in Western countries. It can be very difficult to diagnose as blood cultures are typically negative and a history of rodent exposure is often missed. Unless a high index of suspicion is maintained, the associated polyarthritis can be mistaken for rheumatoid arthritis. We report a case of culture-positive rat bite fever in a 46-year-old female presenting with fever and polyarthritis. The clinical presentation mimicked rheumatoid arthritis. Infection was complicated by discitis, a rare manifestation...

E Carlos Rodriguez-Merchan
Intraarticular (IA) injections of mesenchymal stem cells (MSCs) in idiopathic osteoarthritis (OA) have shown encouraging results in the literature. Hemophilic arthropathy (HA) represents an enormous societal burden. The similarity between OA and HA is very limited. HA resembles much more to the rheumatoid arthritis because a presence of thick synovial membrane and large lymphocytes infiltration. However, in its final stages, HA resembles OA and that is when IA injections of MSCs are commonly used. In this article, we review the concept of IA injections of MSCs as a treatment for HA, using the literature on OA as an example...

Exosomes are small membrane-bound vesicles (30-100 nm) that are secreted by different types of cells and they have been well documented to resemble saucers or flattened spheres under the electron microscope. Recently, evidence indicates that exosomes play important roles in the immune modulation and are associated with the immune pathogenesis of autoimmune diseases, including rheumatoid arthritis (RA), Sjogren's syndrome (SS) and systemic lupus erythematosus (SLE). In this review, we will summarize current research advances of exosomes in immunoregulation, pathogenesis, diagnosis and therapeutics of autoimmune diseases...
