To compare the effectiveness of biologics after rituximab (RTX) treatment in RA.

To assess the value of quantitative vascular imaging by power Doppler US (PDUS) as a tool that can be used to stratify patient risk of joint damage in early seropositive RA while still biologic naive but on synthetic DMARD treatment.

Treatment in general is mostly directly aimed at disease activity, and measures such as the DAS28 might therefore present important additional information. Our aim was to develop and validate a model that uses a combination of disease activity (DAS28) and HAQs to estimate EuroQoL 5-dimension scale (EQ5D) utilities.

To assess the impact of achieving Assessment in SpondyloArthritis international Society 40% (ASAS40) response or an Ankylosing Spondylitis Disease Activity Score inactive disease (ASDAS-ID) state on patient-reported outcomes (PROs) among patients with non-radiographic axial SpA (nr-axSpA).

To evaluate the clinical presentation and long-term outcome of a vasculitis centre cohort of patients with microscopic polyangiitis (MPA) with respect to organ manifestations, treatment, chronic damage and mortality.

Psoriasis and PsA are the main phenotypes of psoriatic disease. Both conditions are highly polygenic diseases in which stochastic and environmental factors are crucial in the pathogenic process. Although the MHC region is a highly dense genetic area, most of the genetic basis of psoriatic disease within it resides in the HLA region. For decades, HLA-C*06 has been accepted as the main descriptor of the two main phenotypes of skin psoriasis. There is now compelling evidence to suggest that HLA-C*06 is only a genetic biomarker for skin involvement and not for joint involvement in psoriatic disease. The role of HLA-B*27 in the genetic aetiology of PsA has been recognized since the 1970s. Recent population case-control studies with adequate patient groups and replication cohorts, as well as confirmation studies in family pedigrees through the use of modern molecular typing methods, have reinforced the aetiological role of this allele in PsA. These studies have offered a new vision of the role of this allele in disease expression. This review contextualizes the latest findings on the role of HLA-B27 in psoriatic disease, emphasizing those aspects of particular interest for clinical practice.

Permanent visual impairment has been reported to occur in up to 19% of GCA patients. The aim of this study was to examine whether implementation of a fast-track approach could reduce the rate of permanent visual impairment and inpatient days of care in GCA patients.

Patients with rheumatoid arthritis (RA) and other inflammatory joint diseases (IJDs) have an increased risk of premature death compared with the general population, mainly because of the risk of cardiovascular disease, which is similar in patients with RA and in those with diabetes mellitus. Pathogenic mechanisms and clinical expression of cardiovascular comorbidities vary greatly between different rheumatic diseases, but atherosclerosis seems to be associated with all IJDs. Traditional risk factors such as age, gender, dyslipidaemia, hypertension, smoking, obesity and diabetes mellitus, together with inflammation, are the main contributors to the increased cardiovascular risk in patients with IJDs. Although cardiovascular risk assessment should be part of routine care in such patients, no disease-specific models are currently available for this purpose. The main pillars of cardiovascular risk reduction are pharmacological and nonpharmacological management of cardiovascular risk factors, as well as tight control of disease activity.

Although new therapeutic options are available for patients with autoinflammatory diseases, evidence-based treatment guidelines are lacking. An initiative in European paediatric rheumatology aims to develop best-practice recommendations for the management of these rare disorders.

Biosimilars, based on biopharmaceuticals approved by regulatory agencies that are no longer under patent protection, have efficacy and safety comparable to their reference products, and are a new therapeutic option to treat inflammatory diseases. Biosimilars must be distinguished from 'biomimics' or 'biocopies', which are marketed in some countries but have not been evaluated according to the stringent regulatory pathway used for biosimilars. CT-P13, based on infliximab, was the first biosimilar approved for the treatment of inflammatory diseases; however, some countries did not allow extrapolation of indications to all eight diseases for which the reference drug infliximab is approved. Antidrug antibodies can reduce drug levels and affect clinical efficacy, but although available data suggest that biosimilars and their reference products have comparable immunogenicity, this important property might differ between individual biopharmaceuticals. This Review discusses biosimilars already approved within the past 3 years to treat rheumatic diseases, as well as others that are currently under development. The main challenges posed by biosimilars are also addressed, such as the extrapolation of indications to diseases only studied for the reference drug, and the definition of strategies for adequate pharmacovigilance to monitor biosimilars after marketing approval.

To determine the prevalence of degenerative changes (DCs) in the spine of young patients with back pain without axial spondyloarthritis (no-axSpA), with possible axSpA (poss-axSpA) and with definite axSpA (axSpA), as shown on MRI and radiographs.
