Introduction: OMERACT uses an evidence-based framework known as the 'OMERACT Filter Instrument Selection Algorithm' (OFISA) to guide decisions in the assessment of outcome measurement instruments for inclusion in a core outcome set for interventional and observational clinical trials.
Methods: A group of OMERACT imaging and patient-centered outcome methodologists worked with imaging outcome groups to facilitate the selection of imaging outcome measurement instruments using the OFISA approach. The lessons learned from this work influenced the evolution to Filter 2.
Objectives: We explored the burden of symptoms of anxiety and depression on health-related quality of life (HRQL) in patients with rheumatoid arthritis (RA).
Methods: Adults with RA participating in an observational cohort completed PROMIS tests of depression, anxiety, fatigue, physical function (PF), pain interference (PI), sleep disturbance, and participation in social roles and activities at the baseline visit. Clinical measures of disease status were also obtained.
Objectives: To analyse the worldwide occurrence of sicca/Sjögren's (SS) syndrome associated with the use of immune checkpoint inhibitors (ICI) in patients with cancer.
Methods: The ImmunoCancer International Registry (ICIR) is a Big Data-Sharing multidisciplinary network composed by 40 specialists in Rheumatology, Internal Medicine, Immunology and Oncology from 18 countries focused on the clinical and basic research of the immune-related adverse events (irAEs) related to cancer immunotherapies. For this study, patients who were investigated for a clinical suspicion of SS after being exposed to ICI were included.
Background: Fatigue is prevalent and impactful in rheumatoid arthritis (RA). There is no standardized measure for its assessment nor data concerning the performance of PROMIS-Fatigue short forms (SFs) in people with RA. We evaluated the construct validity of 4-, 7-, and 8-item PROMIS-Fatigue SFs in RA patients across the range of disease activity.

This study was conducted to determine the ultrasonographic pattern of muscle involvement in patients with inclusion body myositis (IBM) through an assessment of muscle echointensity.
Methods: Sixty-two individuals were consecutively studied, 18 with IBM, 16 with polymyositis or dermatomyositis and 28 normal controls.
Proteolysis of autoantigens can alter normal MHC class II antigen processing and has been implicated in the induction of autoimmune diseases. Many autoantigens are substrates for the protease granzyme B (GrB), but the mechanistic significance of this association is unknown. Peptidylarginine deiminase 4 (PAD4) is a frequent target of autoantibodies in patients with rheumatoid arthritis (RA) and a substrate for GrB.

The advent of new therapeutic agents for the treatment of PsA has made the need for specific outcome measures for PsA more critical to evaluate the heterogeneous manifestations of this disease and features that are unique to its assessment. Several outcome measures have been validated for use in PsA clinical trials while others are being evaluated by groups such as The Group for Assessment of Psoriasis and Psoriatic Arthritis for future use in clinical trials.
