Tumor necrosis factor alpha (TNF-α) has both positive and negative roles in human disease. In certain cancers, TNF-α is infused locally to promote tumor regression, but dose-limiting inflammatory effects limit broader utility. In autoimmune disease, anti-TNF-α antibodies control inflammation in most patients, but these benefits are offset during chronic treatment. TAK1 acts as a key mediator between survival and cell death in TNF-α-mediated signaling. Here, we describe Takinib, a potent and selective TAK1 inhibitor that induces apoptosis following TNF-α stimulation in cell models of rheumatoid arthritis and metastatic breast cancer...

INTRODUCTION: Rheumatoid arthritis (RA) produces debilitating morning stiffness. Exogenous glucocorticoids can help with these symptoms when timed appropriately. Bedtime dosing of delayed-release prednisone (DR-prednisone) matches the rise of inflammatory cytokines before awakening and can improve stiffness and other RA symptoms. A prospective open-label study was conducted in patients currently on stable doses of immediate-release prednisone (IR-prednisone) who were switched to DR-prednisone to analyze the incremental benefit of better timed and lower dose glucocorticoid therapy...

The purpose of this study is to investigate the effect of TSAHC [4'-(p-toluenesulfonylamido)-4-hydroxychalcone] in K/BxN serum transfer arthritis model and fibroblast-like synoviocytes of rheumatoid arthritis (RA-FLS). In in vivo experiments, TSAHC attenuated the incidence and severity of arthritis in comparison with the vehicle group. Histological findings showed that TSAHC decreased the inflammation, bone erosion, cartilage damage, and osteoclasts activity in the ankle. Furthermore, we confirmed by biochemical analysis that the observations were associated with the decreased expression of proinflammatory cytokines, matrix metalloproteinases (MMPs), and RANKL in serum and ankle...

BACKGROUND: Rheumatoid arthritis is characterized by the production of eicosanoids, cytokines, adhesion molecules, infiltration of T and B lymphocytes in the synovium and oxygen reduction accompanied by the cartilage degradation. Eicosanoids are responsible for the progressive destruction of cartilage and bone, however neither steroids, nor the non steroidal anti-inflammatory drugs (NSAIDs), cannot slow down cartilage and bone destruction providing only symptomatic improvement. The current rheumatoid arthritis treatment options include mainly the use of disease-modifying anti-rheumatic drugs, the corticosteroids, the NSAIDs and biological agents...

BACKGROUND: Sjögren's syndrome (SS) shares many clinical and pathological similarities with systemic lupus erythematosus (SLE) and rheumatoid arthritis (RA). These autoimmune diseases mostly affect women. In this study, concept profile analysis (CPA) and gene expression meta-analysis were used to identify genes potentially involved in SS pathogenesis. METHODS: Human genes associated with SS, SLE, and RA were identified using the CPA tool, Anni 2.1. The differential mRNA expression of genes common to SS and SLE (SS-SLE) was determined in female peripheral blood mononuclear cells (PBMCs) using NCBI-GEO2R...

Immunotherapy has been in use for the treatment of melanoma since a very long time, but only recently have the cytotoxic T-lymphocyte antigen-4 (CTLA-4) antibody ipilimumab and programmed cell death-1 inhibitors such as nivolimumab and pembrolizumab been shown to induce marked improvements in survival in patients with metastatic melanoma. An important concern arises in terms of the safety of the use of these agents in patients with autoimmune diseases, solid organ transplant recipients on immunosuppression, patients with a history of previous hepatitis B or C, and patients with HIV infections as these patients were excluded from pivotal immunotherapy studies...

Patients with rheumatoid arthritis (RA) suffer from high rates of depression but depression often remains undiagnosed and untreated among RA patients. Because of its high prevalence and its profound impact on functional disability and health-related quality of life, prompt recognition and management of comorbid depression is urgently needed in patients with RA. Rheumatologists face the challenge of addressing depression in their clinical interactions with patients. The purpose of this paper is to present the prevalence of comorbid depression in RA, to delineate the consequences of depression among RA patients, to discuss the barriers to the identification of depression among RA patients, and to outline a set of recommendations to identify and treat comorbid depression that could be implemented within the rheumatology clinic setting...

The use of multiple data sources has been preferred in the surveillance of adverse drug events due to shortcomings of using only a single source. In this study, we proposed a framework where the ADEs associated with interested drugs are systematically discovered from the FDA's Adverse Event Reporting System (AERS), and then validated through mining unstructured clinical notes from Electronic Medical Records (EMRs). This framework has two features. First, a higher priority was given to clinical practice during signal detection and validation...

The immune and skeletal systems share a variety of molecules, including cytokines, chemokines, hormones, receptors, and transcription factors. Bone cells interact with immune cells under physiological and pathological conditions. Osteoimmunology was created as a new interdisciplinary field in large part to highlight the shared molecules and reciprocal interactions between the two systems in both heath and disease. Receptor activator of NF-κB ligand (RANKL) plays an essential role not only in the development of immune organs and bones, but also in autoimmune diseases affecting bone, thus effectively comprising the molecule that links the two systems...
