OBJECTIVES: Behçet's disease (BD), an auto-inflammatory vasculitis with oro-genital ulcerations, skin lesions and uveitis, is regarded as T cell mediated. A successful trial with rituximab suggests an additive role for B cells in the pathogenesis. Therefore, we studied B cell abnormalities in BD patients and the effect of TNF-blocking therapy. METHODS: B cells in blood (n = 36) and tissue (n = 6) of BD patients were analysed with flow cytometry and/or immunohistochemistry and compared with healthy controls (n = 22)...

SLE is a chronic autoimmune disease involving multiple systems. Patients with SLE are highly susceptible to infections due to the combined effects of their immunosuppressive therapy and the abnormalities of the immune system that the disease itself causes, which can increase mortality in these patients. The differentiation of SLE activity and infection in a febrile patient with SLE is extremely difficult. Activity indexes are useful to identify patients with lupus flares but some clinical and biological abnormalities may, however, make it difficult to differentiate flares from infection...

Neurological and psychiatric syndromes, collectively referred to as NPSLE, occur frequently in SLE. The frequency of NPSLE varies from 21 to 95%; however, only 13-38% of neuropsychiatric (NP) events could be attributable to SLE in the NPSLE SLICC inception cohort. This variability in the frequency of NPSLE is attributable to the low specificity of the ACR case definitions for SLE-attributed NP syndromes, inclusion of minor NP events in the ACR nomenclature, difficulty in ascertainment of NP events and diverse experience of rheumatologists in the clinical assessment of NP events...

OBJECTIVES: The overexpression of IL-12 family cytokines is implicated in the pathogenesis of SSc, but their exact role is still unclear. The aim of this study was to investigate the regulation of extracellular matrix expression by IL-23 and its contribution to the phenotype of SSc. METHODS: The mRNA expression was determined by PCR array and real-time PCR. The expression levels of proteins were determined by immunoblotting and immunohistochemical staining. The effect of IL-23 on dermal fibrosis in vivo was examined in a mouse model of SSc induced by bleomycin injection...

OBJECTIVE: Data on the relationship between disc degeneration (DD) and fragility fractures in men are limited. The aim of this study was to prospectively analyse the risk of vertebral and non-vertebral fractures in men with thoracolumbar DD according to the severity of its radiological signs: disc space narrowing (DSN), osteophytes and endplate sclerosis. METHODS: Men >50 years of age (n = 765) had lateral spine radiographs and DXA and were monitored prospectively...

OBJECTIVES: A national audit was performed assessing the early management of suspected inflammatory arthritis by English and Welsh rheumatology units. The aim of this audit was to measure the performance of rheumatology services against National Institute for Health and Care Excellence (NICE) quality standards (QSs) for the management of early inflammatory arthritis benchmarked to regional and national comparators for the first time in the UK. METHODS: All individuals >16 years of age presenting to rheumatology services in England and Wales with suspected new-onset inflammatory arthritis were included in the audit...

OBJECTIVES: Our aim was to conduct a national audit assessing the impact and experience of early management of inflammatory arthritis by English and Welsh rheumatology units. The audit enables rheumatology services to measure for the first time their performance, patient outcomes and experience, benchmarked to regional and national comparators. METHODS: All individuals >16 years of age presenting to English and Welsh rheumatology services with suspected new-onset inflammatory arthritis were included in the audit...

RA is the most common chronic systemic autoimmune disease, with a higher prevalence in women, suggesting female hormonal factors play a role in the development of the disease. However, many controversies still exist. The aim of this review was to appraise data from recent research concerning female hormonal factors and their association with RA disease development. The study of female hormonal factors is challenging because serum levels may differ throughout a woman's lifetime and interact with various environmental, immunological, genetic and endocrine factors influencing the development of autoimmunity...

OBJECTIVES: Although MRI is recommended for diagnostic use in detecting joint inflammation, its value in clinical practice has not been settled. Older symptom-free persons show more MRI-detected inflammation in their hands and feet. Within arthritis patients, a similar effect could be present (a general age effect). The association of age with MRI inflammation could also be enhanced by disease (disease-dependent age effect). Because both effects could have diagnostic consequences, we evaluated the association between age-at-onset and MRI-detected inflammation in early arthritis and RA...

OBJECTIVES: To evaluate volumetric BMD (vBMD), microarchitecture and strength and vertebral fractures (VFs) in primary SS (pSS). METHODS: We evaluated 71 female pSS patients and 71 gender-, age-, and race-matched controls. Clinical data including risk factors for osteoporosis (OP) and fractures were collected through a standardized protocol. Areal BMD and VFs were analysed by DXA. Bone microarchitecture, vBMD and bone strength were assessed by high-resolution peripheral quantitative CT (HR-pQCT), a non-invasive method...

OBJECTIVES: To investigate the impact of obesity on response to the first TNF-α inhibitor (TNFI) treatment course in patients with PsA followed in routine care. METHODS: We performed an observational cohort study based on the Danish and Icelandic biologics registries. Kaplan-Meier plots, Cox and logistic regression analyses were performed to study the impact of obesity (BMI ⩾30 kg/m(2)) on TNFI adherence and response after 6 months (according to 20/50/70% improvement in ACR criteria and EULAR criteria)...

OBJECTIVES: To determine the change in established biomarkers of cardiovascular (CV) risk, namely, total cholesterol/high-density lipoprotein cholesterol ratio (TC/HDL-C), N-terminal pro-brain natriuretic peptide (NT-proBNP) and insulin resistance (IR) in patients with early RA treated with two different treat-to-target strategies. METHODS: Fasting glucose, lipids, insulin and NT-proBNP were measured at baseline, weeks 26 and 78 in 79 DMARD-naïve RA patients, free of CV disease, as part of a double-blind randomized controlled trial of MTX with either infliximab (IFX) or methylprednisolone as induction therapy...

OBJECTIVES: Septic arthritis is a life-threatening condition with mortality rates of 10-15%. Previous studies in other countries have shown the incidence of septic arthritis may be changing. Our aim was investigate the incidence and pattern of native joint septic arthritis in the UK. METHODS: We performed an analysis using Hospital Episode Statistics to investigate the reported incidence of septic arthritis in the UK between 1998 and 2013. RESULTS: A total of 54 532 cases of septic arthritis were reported via Hospital Episode Statistics during the timeframe studied...
