Patient Profiles in Randomized Controlled Trials Versus a Real-World Study in Psoriatic Arthritis: Scoping Review and Metaanalysis.

Objective: Patients with psoriatic arthritis (PsA) in randomized controlled trials (RCTs) may not reflect patients with PsA in clinical practice. Our objective was to perform a metaanalysis comparing the characteristics of patients with PsA in RCTs of biologic disease-modifying antirheumatic drugs (bDMARDs) to patient profiles in a real-world study.

Methods: Data sources included (1) a scoping literature review of phase III RCTs of bDMARDs in PsA published between 2015 and 2020, and (2) an international observational study of patients with PsA starting a bDMARD enrolled between 2015 and 2018 (PsABio; ClinicalTrials.

Influence of study characteristics on harm estimates from randomised controlled trials in patients with inflammatory arthritis receiving biological or synthetic antirheumatic drugs: a meta-epidemiological study.

Objective: To examine the association between study characteristics and the harms reported in randomised controlled trials (RCTs) on biological and targeted synthetic disease-modifying antirheumatic drugs (b/tsDMARDs) in patients with inflammatory arthritis (IA).

Methods: We searched MEDLINE for all Cochrane reviews and for systematic reviews published since April 2015. RCTs were eligible if they included patients with IA receiving b/tsDMARD, compared with any comparator arm.

Baricitinib as monotherapy for treatment of rheumatoid arthritis: analysis of real-world data.

Objective: Baricitinib is an oral, reversible and selective inhibitor of Janus kinase (JAK)1 and JAK2 that is approved as monotherapy or in combination with methotrexate for the treatment of adults with moderate-to-severe active rheumatoid arthritis (RA) who have responded inadequately to disease-modifying antirheumatic drugs. Evidence supporting the approved monotherapy indication is growing in real-world settings that reflect routine clinical practice.

Methods: Results of separate analyses of real-world data from the observational prospective RA-BE-REAL, Erlangen Baricitinib cohort, the BSRBR-RA, and Swiss Clinical Quality Management in Rheumatic Diseases (SCQM) registries, and the retrospective ORBIT-RA and SUSTAIN long-term chart reviews were reported, documenting baseline data and outcomes for a total of 932 patients with active RA receiving baricitinib as monotherapy.

Phase 2 Trial of Deucravacitinib in Psoriatic Arthritis: Biomarkers Associated With Disease Activity, Pharmacodynamics, and Clinical Responses.

Objective: Our objective was to evaluate the association of serum biomarkers with baseline psoriatic arthritis (PsA) disease activity, pharmacodynamic effects of deucravacitinib on biomarker levels, and the relationship between biomarkers and clinical responses to deucravacitinib.

Methods: The phase 2 trial (ClinicalTrials.gov identifier: NCT03881059) randomly assigned 203 patients with PsA 1:1:1 to placebo, deucravacitinib at 6 mg once daily (QD), or deucravacitinib at 12 mg QD.

Risk of developing psoriatic arthritis in psoriasis cohorts with arthralgia: exploring the subclinical psoriatic arthritis stage.

Objective: Subjects with subclinical psoriatic arthritis (PsA), defined as the presence of arthralgia in psoriasis (PsO), are at higher risk of PsA but scant real-world data exist. Our aims were to (1) estimate the probability of PsA development in subclinical PsA, (2) characterise subclinical PsA symptoms and (3) determine the clinical patterns at PsA diagnosis.

Methods: Patients with PsO, mainly subclinical PsA, were evaluated longitudinally in two European cohorts.

Trends in Systemic Glucocorticoid Utilization in the United Kingdom from 1990 to 2019: A Population-Based, Serial Cross-Sectional Analysis.

Purpose: Associations between systemic glucocorticoid (SGC) exposure and risk for adverse outcomes have spurred a move toward steroid-sparing treatment strategies. Real-world changes in SGC exposure over time, after the introduction of steroid-sparing treatment strategies, reveal areas of successful risk mitigation as well as unmet needs.

Patients And Methods: A population-based ecological study was performed from the Optimum Patient Care Research Database to describe SGC prescribing trends of steroid-sparing treatment strategies in primary care practices before and after licensure of biologics in the United Kingdom from 1990 to 2019.

Objective: We analyzed the impact of amino acid (AA) availability on the inflammatory response in arthritis.

Methods: We stimulated rheumatoid arthritis (RA) fibroblast-like synoviocytes (FLSs) with tumor necrosis factor (TNF) in the presence or absence of proteinogenic AAs and measured their response by QuantSeq 3' messenger RNA sequencing, quantitative polymerase chain reaction, and enzyme-linked immunosorbent assay. Signal transduction events were determined by Western blot.

Charles L Christian: Model Physician Scientist and Mentor.

Dr Charles L Christian arrived in New York City in 1953, having grown up in Wichita, Kansas, and graduating from medical school at Case Western Reserve in Cleveland, Ohio. In New York, Dr Christian embarked on training in internal medicine at Columbia's Presbyterian Hospital where he met an individual who would shape the course of his career, Dr Charles Ragan, a founder of the Arthritis Foundation. Dr Christian, or Chuck as he was usually called, went on to shape the developing field of rheumatology, advancing understanding of our most complex diseases as an investigator, master clinician, mentor, and academic leader.

2023 International Consensus Guidance for the use of Tripterygium Wilfordii Hook F in the treatment of active rheumatoid arthritis.

Background: Rheumatoid arthritis (RA) is a chronic autoimmune disorder that affects the joints and produces pain, swelling, and stiffness. It has a lifetime prevalence of up to 1% worldwide. An extract of Tripterygium wilfordii Hook F (TwHF), a member of the Celastraceae herbal family widely available in south China, has been used for treatment of RA since 1960s.

Selectivity, efficacy and safety of JAKinibs: new evidence for a still evolving story.

Fundamental insight gained over the last decades led to the discovery of cytokines as pivotal drivers of inflammatory diseases such as rheumatoid arthritis, psoriasis/psoriasis arthritis, inflammatory bowel diseases, atopic dermatitis and spondylarthritis. A deeper understanding of the pro-inflammatory and anti-inflammatory effects of various cytokines has prompted new cytokine-targeting therapies, which revolutionised the treatment options in the last years for patients with inflammatory disorders. Disease-associated immune responses typically involve a complex interplay of multiple cytokines.

Definition of rheumatoid arthritis flare based on SDAI and CDAI.

Objective: To develop and validate definitions for disease flares in rheumatoid arthritis (RA) based on the quantitative Simplified and Clinical Disease Activity Indices (SDAI, CDAI).

Methods: We analysed RA treatment courses from the Norwegian disease-modifying antirheumatic drug registry (NOR-DMARD) and the Vienna RA cohort. In a receiver operating curve analysis, we determined flare definitions for absolute changes in SDAI and CDAI based on a semiquantitative patient anchor.
