Applying SLICC and ACR/EULAR systemic lupus erythematosus classification criteria in a cohort of patients with undifferentiated connective tissue disease.

Background/objective: New classification criteria for SLE have recently been developed. How these criteria affect the classification of patients with the SLE-mimicking condition UCTD is poorly understood. This study investigated the reclassification of UCTD patients using newly derived SLE criteria.

A Novel Mobile App and Population Management System to Manage Rheumatoid Arthritis Flares: Protocol for a Randomized Controlled Trial.

Background: Rheumatoid arthritis flares have a profound effect on patients, causing pain and disability. However, flares often occur between regularly scheduled health care provider visits and are, therefore, difficult to monitor and manage. We sought to develop a mobile phone app combined with a population management system to help track RA flares between visits.

Vascular calcifications on hand radiographs in rheumatoid arthritis and associations with autoantibodies, cardiovascular risk factors and mortality.

Objective: To examine whether vascular calcifications on hand films in RA might aid in determining mortality risk.

Methods: Hand radiographs from 906 RA patients were scored as positive or negative for vascular calcifications. Patient characteristics associated with vascular calcifications were assessed using multivariable logistic regression, and associations with mortality were examined using Cox proportional hazards regression.

Cardiovascular risk and the use of biologic agents in rheumatoid arthritis.

Although patients with rheumatoid arthritis (RA) are recognized to be disproportionately impacted by cardiovascular disease (CVD), effective approaches of primary and secondary CVD prevention have not been well defined in this population. Given their robust disease-modifying potential and effects on both pro-inflammatory and pro-atherogenic pathways, there has been substantial speculation that biologic treatments may serve as a means of providing highly effective RA disease control while simultaneously reducing CVD risk in this high risk group. In this review, we examine available evidence relevant to the associations of approved biologic treatments with CVD outcomes in the context of RA.

Anticitrullinated protein antibody (ACPA) in rheumatoid arthritis: influence of an interaction between HLA-DRB1 shared epitope and a deletion polymorphism in glutathione S-transferase in a cross-sectional study.

Introduction: A deletion polymorphism in glutathione S-transferase Mu-1 (GSTM1-null) has previously been implicated to play a role in rheumatoid arthritis (RA) risk and progression, although no prior investigations have examined its associations with anticitrullinated protein antibody (ACPA) positivity. The purpose of this study was to examine the associations of GSTM1-null with ACPA positivity in RA and to assess for evidence of interaction between GSTM1 and HLA-DRB1 shared epitope (SE).

Methods: Associations of GSTM1-null with ACPA positivity were examined separately in two RA cohorts, the Veterans Affairs Rheumatoid Arthritis (VARA) registry (n = 703) and the Study of New-Onset RA (SONORA; n = 610).

Shoulder arthroplasties have fewer complications than hip or knee arthroplasties in US veterans.

Unlabelled: Total shoulder arthroplasties (TSA) are being performed more commonly for treatment of arthritis, although fewer than either hip (THA) or knee (TKA) arthroplasties. Total shoulder arthroplasty also provides general health improvements that are comparable to THA. One study suggests TSAs are associated with lower morbidity and mortality than THAs and TKAs.
