A prospective, longitudinal monocentric study on laser Doppler imaging of microcirculation: comparison with macrovascular pathophysiology and effect of adalimumab treatment in early rheumatoid arthritis.

Increased cardiovascular (CV) morbidity and mortality have been found in rheumatoid arthritis (RA). Tumour necrosis factor α (TNF-α) inhibitors may improve vascular function. In the first part of this study, we determined microcirculation during postoocclusive reactive hyperemia (PORH) representing endothelial function.

Effects of 1-year anti-TNF-α therapy on vascular function in rheumatoid arthritis and ankylosing spondylitis.

Accelerated atherosclerosis, increased cardiovascular morbidity and mortality have been associated with rheumatoid arthritis (RA) and ankylosing spondylitis (AS). Vascular function, clinical and laboratory markers and the effects of anti-TNF therapy were assessed in arthritides. Fifty-three 53 patients including 36 RA patients treated with either etanercept (ETN) or certolizumab pegol and 17 AS patients treated with ETN were included in a 12-month follow-up study.

Effects of 1-year anti-TNF-α therapies on bone mineral density and bone biomarkers in rheumatoid arthritis and ankylosing spondylitis.

Objectives: Rheumatoid arthritis (RA) and ankylosing spondylitis (AS) have been associated with generalized and localized bone loss. We conducted a comprehensive study using imaging (dual-energy X-ray absorptiometry, DXA) and laboratory biomarkers in order to determine bone health and to study the effects of anti-tumor necrosis factor (TNF) biologics in RA and AS.

Patients And Methods: Thirty-six RA and 17 AS patients undergoing 1-year etanercept (ETN) or certolizumab-pegol (CZP) therapy were studied.

Gene expression analysis of vascular pathophysiology related to anti-TNF treatment in rheumatoid arthritis.

Objectives: Impaired vascular pathophysiology and increased cardiovascular (CV) mortality are associated with rheumatoid arthritis (RA). To date, no genomic analysis of RA- and RA treatment-related vascular pathophysiology has been published. In this pilot study, we performed gene expression profiling in association with vascular pathophysiology in RA patients.

Comparison of peripheral quantitative computed tomography forearm bone density versus DXA in rheumatoid arthritis patients and controls.

Unlabelled: Rheumatoid arthritis (RA) has been associated with osteoporosis. Quantitative computed tomography (QCT) is capable of assessing bone density and composition. We found lower bone density in RA compared to controls.

[Insight into the training of patients with idiopathic inflammatory myopathy].

Using current recommended treatment, a majority of patients with idiopathic inflammatory myopathy develop muscle impairment and poor health. Beneficial effects of exercise have been reported on muscle performance, aerobic capacity and health in chronic polymyositis and dermatomyositis, as well as in active disease and inclusion body myositis to some extent. Importantly, randomized controlled trials indicate that improved health and decreased clinical disease activity could be mediated through increased aerobic capacity.

[New insights of myositis-specific and -associated autoantibodies in juvenile and adult type myositis].

Myositis, which means inflammation of the muscles, is a general term used for inflammatory myopathies. Myositis is a rare idiopathic autoimmune disease. It is believed that environmental factors such as virus, bacteria, parasites, direct injuries, drugs side effect can trigger the immune system of genetically susceptible individuals to act against muscle tissues.

Combination of IgG N-glycomics and corresponding transcriptomics data to identify anti-TNF-α treatment responders in inflammatory diseases.

Prediction of responsiveness in biological therapies is an important and challenging issue in different diseases. Analyzing glycosylation pattern changes of key serum glycoproteins is one of the possible avenues to follow disease remission. The aim of this study was to investigate the changes of serum IgG glycoforms in Crohn's disease (CD) and rheumatoid arthritis patients in response to antitumor necrosis factor alpha (anti-TNF-α) treatment.

Real-life experience with switching TNF-α inhibitors in ankylosing spondylitis.

Objective: The aim of this study was to evaluate the efficacy, reasons for switching and drug survival of TNF-α inhibitors (TNFis) used as first- and second-line drugs in ankylosing spondylitis (AS).

Methods: Data on patients suffering from AS and treated with at least one TNFi between November 2005 and 2013 were extracted retrospectively from the database of a single clinical centre. Beside demographic data, the disease activity measured by the Bath Ankylosing Spondylitis Disease Activity Index (BASDAI), the response rates (BASDAI50), reasons for switching and survival curves of TNFis were analysed in general and in subgroups of patients treated with each of the available TNFis.

Peripheral blood derived gene panels predict response to infliximab in rheumatoid arthritis and Crohn's disease.

Background: Biological therapies have been introduced for the treatment of chronic inflammatory diseases including rheumatoid arthritis (RA) and Crohn's disease (CD). The efficacy of biologics differs from patient to patient. Moreover these therapies are rather expensive, therefore treatment of primary non-responders should be avoided.

Pharmacogenetics and pharmacogenomics in rheumatology.

Pharmacogenetics and pharmacogenomics deal with possible associations of a single genetic polymorphism or those of multiple gene profiles with responses to drugs. In rheumatology, genes and gene signatures may be associated with altered efficacy and/or safety of anti-inflammatory drugs, disease-modifying antirheumatic drugs (DMARDs) and biologics. In brief, genes of cytochrome P450, other enzymes involved in drug metabolism, transporters and some cytokines have been associated with responses to and toxicity of non-steroidal anti-inflammatory drugs, corticosteroids and DMARDs.

Longterm effects of rituximab on B cell counts and autoantibody production in rheumatoid arthritis: use of high-sensitivity flow cytometry for more sensitive assessment of B cell depletion.

Objective: To assess the efficacy and safety of longterm rituximab (RTX) therapy for rheumatoid arthritis (RA) and study correlations among B cell depletion, clinical response, and autoantibody production.

Methods: Seventy-seven patients with moderate or high RA activity received RTX and were re-treated every 6 months regardless of clinical response. All patients received at least 5 cycles.

Effects of adalimumab treatment on vascular disease associated with early rheumatoid arthritis.

Background: Increased cardiovascular morbidity has become a leading cause of mortality in rheumatoid arthritis (RA). Tumor necrosis factor-alpha (TNFa) inhibitors may influence flow-mediated vasodilation (FMD) of the brachial artery, common carotid intima-media thickness (ccIMT) and arterial stiffness indicated by pulse-wave velocity (PWV) in RA.

Objectives: To assess the effects of adalimumab treatment on FMD, ccIMT and PWV in early RA.

Pretreatment T lymphocyte numbers are contributing to the prognostic significance of absolute lymphocyte numbers in B-cell non-Hodgkins lymphomas.

Targeted immuno-chemotherapy resulted in greatly improved survival of B cell lymphoma patients. Several prognostic markers are investigated, amongst them the pretreatment absolute lymphocyte numbers. We investigated lymphocyte subpopulations and correlated this data with prognosis of patients.

Biologics - beyond the joints.

Biologics including tumor necrosis factor α (TNF-α), interleukin-6 receptor (IL-6R), T and B cell inhibitors are very effective therapeutic agents for the treatment of arthritides. These compounds effectively improve articular symptoms and inhibit joint damage. In this respect, there are no major differences in the efficacy of the available biologics.

Myositis-specific and myositis-associated antibodies in overlap myositis in comparison to primary dermatopolymyositis: Relevance for clinical classification: retrospective study of 169 patients.

Objective: The current study was performed in order to determine the prevalence of different myositis-specific and myositis-associated antibodies, as well as their association with clinical characteristics, disease course and response to therapy in 169 Hungarian patients with idiopathic inflammatory myopathy.

Methods: Sera of 130 primary and 39 overlap myositis including systemic sclerosis (13), rheumatoid arthritis (12), systemic lupus erythematosus (5) and Sjögren's syndrome (9) cases were analyzed.

Characteristics of interstitial lung disease in SS-A positive/Jo-1 positive inflammatory myopathy patients.

The strongest predictive factor for the development of interstitial lung disease (ILD) in myositis (IIM) patients is the presence of different antisynthetase antibodies. The aim of this study was to compare the clinical characteristics, radiological findings and therapeutic response between the anti-SS-A positive and negative antisynthetase syndrome (ASS) patients. A prospective study of 315 IIM patients was conducted including 27 anti-Jo-1 positive ASS patients.

[Inclusion body myositis pathomechanism and therapy].

Inclusion body myositis is an acquired inflammatory muscle disease belonging to the family of idiopathic inflammatory myopathy with vacuole formation. Approximately 15-28% of idiopathic inflammatory myopathy patients suffer from inclusion body myositis. Early diagnosis is very important due to the slowly progressive disease course and consecutive muscle atrophy.
