Treatment with tumor necrosis factor-α inhibitors is a risk factor for tuberculosis. Despite previous treatment with isoniazid for latent tuberculosis, a 9-year-old girl with juvenile idiopathic arthritis developed disseminated tuberculosis after changing therapy with etanercept to adalimumab and after new contact with a smear-positive relative. Genotyping strain matches and susceptibility to isoniazid make reinfection more likely than reactivation in our patient.

Rituximab is a chimeric monoclonal antibody directed at the CD20 molecule on the surfaces of some but not all B cells. It depletes almost all peripheral B cells, but other niches of B cells are variably depleted, including synovium. Its mechanism of action in rheumatoid arthritis (RA) is only partially understood. Rituximab was efficacious in clinical trials of patients with RA, including those who are methotrexate naïve, those with an incomplete response to methotrexate, and those with an incomplete response to tumor necrosis factor inhibitors...

OBJECTIVE: Neck pain is common in rheumatoid arthritis (RA) and ankylosing spondylitis (AS). We investigated the correlation of bone marrow edema (BME) on magnetic resonance imaging (MRI) in RA and AS and its association with clinical complaints of neck pain. METHODS: Cervical spine short-tau inversion recovery-MRI and T1w-MRI of 34 patients with RA and 6 patients with AS complaining about neck pain were obtained. Clinical and laboratory data were available. BME was scored by 2 blinded readers using a modification of a published score, including various cervical sites...

Rheumatoid arthritis (RA) is a chronic inflammatory autoimmune disorder. Hydrogen sulfide (H2S), the third physiological gasotransmitter, is well recognized as an anti-inflammatory mediator in various inflammatory conditions. Herein, we explored the protective effects of S-propargyl-cysteine (SPRC, also known as ZYZ-802), an endogenous H2S modulator, on RA and determined the underlying mechanisms. In the present study, SPRC concentration-dependently attenuated inflammatory mediator expression, reactive oxidase species generation, and the expression and activity of matrix metalloproteinases (MMP)-9 in interleukin (IL)-1β-induced human rheumatoid fibroblast-like synoviocytes MH7A...

Monocytes of patients with ankylosing spondylitis (AS) have toll-like receptor 4 (TLR4) overexpression on their monocytes. Myeloid-related protein (MRP) 8/14 protein complexes are calcium-binding proteins, which act as endogenous ligands to TLR4. Thus, we studied the levels of MRP8/14 in adult AS patients. MRP8/14 levels were assessed in 99 adult AS patients satisfying Assessments in Ankylosing Spondylitis International Society 2010 criteria and 71 healthy controls by ELISA. Patient disease parameters like patient and physician global assessment, Bath Ankylosing Spondylitis Disease Activity Index (BASDAI), swollen and tender joint count, entheseal count by Maastricht enthesitis index, erythrocyte sedimentation rate (ESR), and C-reactive protein (CRP) were also recorded...

BACKGROUND: Previous studies suggested that obesity could negatively affect the response to anti-tumor necrosis factor α (TNFα) agents in rheumatoid arthritis (RA). However, data are lacking on whether obesity affects the response to abatacept (ABA). We aimed to determine whether body mass index (BMI) affects the response to ABA in RA. PATIENTS AND METHODS: In this multicenter retrospective study, we included RA patients who received ABA. BMI was calculated at the initiation of treatment...

In patients with rheumatic diseases, reliable markers for determining disease activity are scarce. One potential parameter is the level of immunoglobulin free light chains (FLCs), which is known to be elevated in the blood of patients with certain rheumatic diseases. Few studies have quantified FLCs in urine, a convenient source of test sample, in patients with different rheumatic diseases. We carried out a retrospective analysis of patients with rheumatic disease attending the University hospital of Goettingen, Germany...

OBJECTIVE: In rheumatoid arthritis (RA), endothelial dysfunction caused by the inflammatory process increases the risk of cardiovascular disease. Asymmetric Dimethylarginine (ADMA) leads to vascular dysfunction, whereas atherosclerosis and increased ADMA is associated with cardiovascular disease risk factors. Flow-mediated Dilation (FMD) is a radiological method to demonstrate endothelial dysfunction. In the present study, we assessed the availability of ADMA as a marker for endothelial dysfunction in RA patients...

HLA-DR-molecules are highly expressed in synovial tissue (ST), the target of the immune response in chronic inflammatory forms of arthritis. Here, we used LC-MS/MS to identify HLA-DR-presented self-peptides in cells taken directly from clinical samples: ST, synovial fluid mononuclear cells (SFMC), or peripheral blood mononuclear cells (PBMC) from five patients with rheumatoid arthritis (RA) and eight with Lyme arthritis (LA). We identified 1,593 non-redundant HLA-DR-presented peptides, derived from 870 source proteins...

The prognostic significance of early diagnosis and therapeutic intervention in inflammatory rheumatic diseases has been well documented. However, a shortage of rheumatologists often impedes this approach in clinical practice. Therefore, it is of importance to identify those patients referred for diagnosis who would benefit most from a specialist's care. We applied a telephone-based triage for appointment allocation during routine care. This retrospective, monocentric analysis evaluated the efficacy of our triage to identify patients with rheumatic disease with special regard to initial appointment category (elective, early arthritis clinic (EAC), or emergency appointment)...

Rheumatoid arthritis (RA) is an autoimmune, inflammatory joint disease whose exact cause is still not completely known. Reactive oxygen species (ROS) are believed to be involved in the pathogenesis of RA. ROS are produced mostly by the phagocytic cells during oxidative burst and oxidative phosphorylation. Lipids, proteins and nucleic acids get damaged by the overproduction of ROS. Damaging effects of ROS are taken care by the enzymatic and non-enzymatic defence system of the body. Overproduction or inadequate elimination of reactive species leading to oxidative stress has been positively correlated with the disease severity in RA patients...

BACKGROUND: Increased expression of toll-like receptor 4 (TLR4) and its endogenous ligands, is characteristic of rheumatoid arthritis (RA) synovitis. In this study, we evaluated how these TLR4 ligands may drive pathogenic processes and whether the fine profiling of anti-citrullinated protein antibodies (ACPA) based on their target specificity might provide a simple means to predict therapeutic benefit when neutralizing TLR4 in this disease. METHODS: The capacity of RA synovial fluids (RASF) to stimulate cytokine production in monocytes from patients with RA was analyzed by ELISA...

BACKGROUND: Long noncoding RNAs (lncRNAs) have recently received wide attention as key molecules that mediate a variety of physiological and pathological processes by regulating gene expression; however, knowledge of lncRNAs in rheumatoid arthritis (RA) is limited. Thus, we investigated the lncRNA expression profile in fibroblast-like synoviocytes (FLSs) from patients with RA and explored the function of abundantly expressed lncRNAs. METHODS: LncRNA and mRNA microarrays were performed to identify differentially expressed lncRNAs in RA FLSs compared with normal FLSs...
