OBJECTIVES: To investigate the ability of different EQ-5D-3L index scores to discriminate between verum drug and placebo (discriminant validity) as well as between responders and non-responders (known-groups validity) in the SLE patient population of two phase III clinical trials of belimumab. METHODS: Data from the BLISS-52 (NCT00424476) and BLISS-76 (NCT00410384) trials (N = 1684), which both showed superiority of belimumab to placebo, were utilised...

OBJECTIVES: Osteoarthritis has been the subject of abundant research in the last years with limited translation to the clinical practice, probably due to the disease's high heterogeneity. In this study, we aimed to identify different phenotypes in Knee osteoarthritis (KOA) patients with joint effusion based on their metabolic and inflammatory profiles. METHODS: A non-supervised strategy based on Statistical and Machine Learning methods was applied to 45 parameters measured on 168 female KOA patients with persistent joint effusion, consecutively recruited at our hospital after a monographic OA outpatient visit...

OBJECTIVES: The variable region of most ACPA IgG molecules in the serum of RA patients carries N-glycan (N-glycanV). To analyze the pathogenicity of N-glycanV of ACPAs, we analyzed the pathogenicity of a monoclonal ACPA, CCP-Ab1, with or without N-glycanV, which had been isolated from a patient with RA. METHODS: CCP-Ab1 with no N-glycosylation site in the variable region (CCP-Ab1 N-rev) was generated and antigen binding, the effect on in vitro differentiation of osteoclasts from bone marrow mononuclear cells of autoimmune arthritis-prone SKG mice (the cell size of TRAP+ cells and bone resorption capacity), and the in vivo effect on the onset or exacerbation of autoimmune arthritis in SKG mice were evaluated in comparison to glycosylated CCP-Ab1...

OBJECTIVES: Etanercept biosimilars show comparable efficacy to their originators among biologic-naïve patients with RA in RCTs. Nationwide guidelines have obligated prescribing of etanercept biosimilars from 2016 resulting in significant cost-savings. This analysis aimed to compare the effectiveness of etanercept originator versus etanercept biosimilar amongst biologic-naïve RA patients treated in routine clinical-practice in the UK. METHODS: Biologic-naïve RA patients starting etanercept in the BSRBR-RA cohort study from 2010 were included...

OBJECTIVES: In patients with gout there is a lack of longitudinal studies on the course of work productivity. We explored longitudinal changes in and predictors of work productivity over 2 years. METHODS: Patients in the NOR-Gout observational study with a recent gout flare and serum urate (sUA) >360 µmol/l attended tight-control visits during escalating urate lowering therapy according to a treat-to target strategy. From the Work Productivity and Activity Impairment Questionnaire (WPAI) scores for work productivity and activity impairment were assessed over 2 years together with the Beliefs about Medicines Questionnaire (BMQ) and a variety of demographic and clinical variables...

OBJECTIVES: To examine the effect of pre-course e-learning on residents' practical performance in musculoskeletal ultrasound (MSUS). METHODS: Multicentre, randomized controlled study following the CONSORT statement. Residents with no or little MSUS experience were randomized to either an e-learning group or a traditional group. One week before a 2-day face-to-face MSUS course, the e-learning group received access to an interactive platform consisting of online lectures, assignments, and practical instruction videos aligned with the content of the course...

OBJECTIVES: Although the systemic lupus erythematosus disease activity score (SLE-DAS) and its definitions to classify disease activity have been recently developed to overcome the drawbacks of the SLE Disease Activity Index 2000 (SLEDAI-2K), the performance of the SLE-DAS for patient-reported outcomes (PROs) has not been fully examined. We aimed to compare SLE-DAS with SLEDAI-2K and validate the classifications of disease activity based on SLE-DAS in terms of PROs. METHODS: We assessed generic quality of life (QoL) using the Medical Outcome Survey 36-Item Short-Form Health Survey (SF-36), disease-specific QoL using the Lupus Patient-Reported Outcome tool (LupusPRO), burden of symptoms using the SLE Symptom Checklist (SSC), patient global assessment (PtGA), and physician global assessment (PhGA)...

OBJECTIVES: To investigate computer-aided quantitative scores from high-resolution CT (HRCT) images and determine their longitudinal changes and clinical significance in patients with idiopathic inflammatory myopathies (IIMs)-related interstitial lung disease (IIMs-ILD). METHODS: The clinical data and HRCT images of 80 patients with IIMs who underwent serial HRCT scans at least twice were retrospectively analysed. Quantitative ILD (QILD) scores (%) were calculated as the sum of the extent of lung fibrosis, ground-glass opacity, and honeycombing...

OBJECTIVE: The ACR-EULAR myositis response criteria (MRC) were developed as a composite measure using absolute percentage change in six core set measures (CSMs). We aimed to further validate the MRC by assessing the contribution of each CSM, frequency of strength versus extramuscular activity improvement, representation of patient-reported outcome measures (PROM), and frequency of CSM worsening. METHODS: Data from adult dermatomyositis/polymyositis patients in the rituximab (n = 147), etanercept (n = 14), and abatacept (n = 19) trials, and consensus patient profiles (n = 232) were evaluated...

OBJECTIVES: The 2016 ACR-EULAR Response Criteria for juvenile dermatomyositis (JDM) was developed as a composite measure with differential weights of six core set measures (CSMs) to calculate a Total Improvement Score (TIS). We assessed the contribution of each CSM, representation of muscle-related and patient-reported CSMs towards improvement, and frequency of CSM worsening across myositis response criteria (MRC) categories in validation of MRC. METHODS: Data from JDM patients in the Rituximab in Myositis trial (n = 48), PRINTO JDM trial (n = 139), and consensus patient profiles (n = 273) were included...

OBJECTIVES: To assess the prevalence of ultrasound (US)-confirmed enthesitis in a cohort of patients with systemic lupus erythematosus (SLE) and to analyze the clinical associations to enthesitis during the course of SLE. METHODS: In a retrospective analysis of the SLE cohort of the Lupus Unit of the Careggi University Hospital, US examinations of SLE patients presenting with tender and/or swollen joints were retrieved to assess the presence of enthesitis. Patients with US-proven enthesitis were compared with SLE controls with tender and/or swollen joints who showed no US-evidence of enthesitis...

OBJECTIVES: N-terminal fragment of titin (N-titin) is a marker of sarcomere damage in striated muscles, however, its value in patients with IIM is unclear. This study aimed to investigate the diagnostic value of N-titin for skeletal muscle damage in patients with IIM. METHODS: Urine samples from 62 patients with IIM, 59 patients with other CTD diseases, and 29 healthy controls were collected to detect N-titin by ELISA assays. Clinical features and laboratory data were all included in logistic regression analysis to obtain the independent predictive factor for skeletal muscle damage...

OBJECTIVES: To determine long-term (20 year) survival in RA patients enrolled in the Australian Rheumatology Association Database (ARAD). METHODS: ARAD patients with RA and data linkage consent who were diagnosed from 1995 onwards were included. Death data were obtained through linkage to the Australian National Death Index. Results were compared with age, gender and calendar year matched Australian population mortality rates.Analysis included both the standardised mortality ratio (SMR) and relative survival models...
