Background: To assess how common it is for a published network meta-analysis (NMA) to have other published overlapping NMAs, and to evaluate these overlaps. Methods: A total of 88 NMAs of randomized controlled trials evaluating the comparative effectiveness of health interventions were randomly selected. For each of these, we searched for NMAs on the same topic. A random sample of 40 pairs (an index NMA and one of its overlapping NMAs) was selected to assess the overlap in terms of nodes, treatments and references...

The PTPN22R620W single nucleotide polymorphism increases the risk of developing multiple autoimmune diseases including type 1 diabetes, rheumatoid arthritis and lupus. PTPN22 is highly expressed in antigen presenting cells (APCs) where the expression of the murine disease associated variant orthologue (Ptpn22R619W) is reported to dysregulate pattern recognition receptor signalling in dendritic cells (DCs) and promote T-cell proliferation. Because T-cell activation is dependent on DC antigen uptake, degradation and presentation, we analysed the efficiency of these functions in splenic and GM-CSF bone marrow derived DC from wild type (WT), Ptpn22-/- or Ptpn22R619W mutant mice...

BACKGROUND/AIMS: Rheumatoid arthritis is a chronic autoimmune disease hallmarked by inflammation in synovial joints. Treatment is hampered by the lack of a cure and current disease-modifying drugs are associated with potentially severe toxicities. METHODS: We investigated arthritis severity by measuring joint swelling and pro-inflammatory cytokine production in a murine experimental model of inflammatory arthritis (antigen-induced arthritis). We analyzed acid sphingomyelinase knock-out mice and wild-type littermates, as well as mice treated with the pharmacological acid sphingomyelinase inhibitor amitriptyline...

BACKGROUND AND AIMS: The effects of low dose prednisolone on circulating markers of endothelial function, the arginine metabolites asymmetric dimethyl arginine (ADMA), mono methyl arginine (MMA), and homoarginine, are uncertain. We assessed whether patients with rheumatoid arthritis have perturbations in arginine metabolite concentrations that are reversed by low dose prednisolone. METHODS: Eighteen rheumatoid arthritis patients who had not taken prednisolone for >6 months (non-glucocorticoid (GC) users), 18 rheumatoid arthritis patients taking continuous oral prednisolone (6...

BACKGROUND: Endometriosis is a gynaecological disease exhibiting severe pelvic pain, but the mechanism of pain production remains unknown. Bradykinin (BK) is known as an inflammatory mediator, and shows elevated levels in inflammatory diseases such as rheumatoid arthritis. In the present study, we evaluated whether BK is involved in endometriosis-related pain. METHODS: Endometriotic lesions were used for immunohistochemistry. Primary cultures of endometriotic stromal cells (ESC) were stimulated with IL-1β and/or BK...

Current literature has overlooked the impact of chronic illness on masculine identity. We therefore aimed to investigate the impact of rheumatoid arthritis (a long term condition, affecting more women than men) on masculine identity. Six focus groups with 22 men with rheumatoid arthritis (RA) (data reported elsewhere) followed by five one-to-one interviews with men (English, mean age: 59 years) sampled to reflect a heterogeneous experience of life with RA based on knowledge gained from the focus groups. Transcripts were analysed using thematic analysis and are presented as individual case studies...

Rheumatoid arthritis (RA) is associated with HLA-DRB1 shared epitope (HLA-DRB1SE) and anti-citrullinated protein autoantibodies (ACPAs). ACPAs precedes the onset of clinical and subclinical RA. There are strong data for three infectious agents as autoimmunity triggers in RA, namely Porphyromonas gingivalis and Aggregatibacter actinomycetemcomitans causes of periodontal disease (PD), and Epstein-Barr virus (EBV). P. gingivalis expresses arginine gingipains, that cleave proteins at the arginine residues, and peptidyl arginine deiminase (PPAD), which citrullinates arginine residues of proteins, thus forming neoantigens that lead to ACPA production...

Alemtuzumab, a humanized anti-CD52 monoclonal antibody, is approved for the treatment of active relapsing-remitting multiple sclerosis (MS). Alemtuzumab induces a rapid and prolonged depletion of lymphocytes from the circulation, which results in a profound immuno-suppression status followed by an immune reconstitution phase. Secondary to reconstitution autoimmune diseases represent the most common side effect of Alemtuzumab treatment. Among them, Graves' disease (GD) is the most frequent one with an estimated prevalence ranging from 16...

Anti-tumor necrosis factor α (TNF-α) biologic agents are used for treating refractory sarcoidosis. However, sarcoidosis-like epithelioid cell granulomas may develop during anti-TNF-α treatment. A 63-year-old man suffering from rheumatoid arthritis was treated with oral methotrexate and methylprednisolone for 4 years. He subsequently started biweekly subcutaneous injections of certolizumab pegol. Three months later, light red follicular papules developed on his chest and they spread over the trunk and bilateral upper arms...

Mourad F Rezk, Burkhard Pieper
Over the years, biologic agents have proven their importance in the management of chronic autoimmune diseases, such as rheumatoid arthritis, psoriasis, and inflammatory bowel disease. Biosimilars, which are biologic medicines, are highly similar to approved biologic medicines, and are comprehensively developed and rigorously tested to ensure efficacy and safety are similar to the reference product. A broader armamentarium of biosimilars is expected to improve patients' access to safe and effective biologic medicines, thus offering benefits to healthcare systems around the globe...

BACKGROUD: Dipeptidyl peptidase I (DPPI), a lysosomal cysteine protease is derived from granule immune cells including mast cell, neutrophils, and toxicity T cells. DPPI can activate serine proteases by removal of dipeptides from N-termini of the pro-proteases, resulting in granule immune cells activation which involved in physiological or pathological responses. Triperygium Wilfordii Polyglucoside (TWP) is one of the traditional Chinese medicines, and commonly used in rheumatoid arthritis (RA) treatment...

Mutations of the COPA gene cause an immune dysregulatory disease characterised by polyarticular arthritis and progressive interstitial lung disease with pulmonary haemorrhages. We report the case of a young girl that presented at age 3 with polyarticular arthritis, chronic cough and high titer rheumatoid factor. Radiologic imaging showed interstitial lung disease with tree-in-a-bud nodules and air-filled cysts. Targeted genetic analysis of COPA gene showed the reported c.698G>A mutation. The patient was lost to follow up for 3years during which therapy was discontinued with the development of joint damage and deformities...

Baseline sympathetic activity was found to be elevated in rheumatoid arthritis (RA) patients and it is related to increased cardiovascular risk in these patients. Although many studies have highlighted the association between RA and increased cardiac sympathetic activity, the underlying mechanistic links remain unclear. The aim of the present study was to understand how diseases-triggered changes in gene expression may result in maladaptive physiological changes. Our results suggest that the equilibrium between noradrenaline synthesis, release and reuptake was disrupted in the ventricles of arthritic rats...

Rheumatoid arthritis is a chronic autoimmune disease characterized by infiltration of inflammatory cells into the synovium and destruction of cartilage and bone. Macrophages, fibroblast-like synoviocytes (FLS), and osteoclasts are critical cells driving the pathogenesis of RA. Semaphorin 3A (Sema3A) is recently identified as an essential player in the bone homeostasis, however its role in RA progression especially in the macrophage polarization are poorly understood. In the present study, we found that Sems3A levels were significantly decreased in RA serum and synovial fluid compared to OA controls...
