OBJECTIVE: The objective was to ascertain pegloticase persistence and adverse events associated with concomitant immunomodulatory drug use in patients with gout. METHODS: We conducted a retrospective analysis of gout patients using the ACR's Rheumatology Informatics System for Effectiveness (RISE) registry from 1/2016 through 6/2020. The first pegloticase infusion defined the index date. Based on concomitant immunomodulatory drug use, we identified 3 exposure groups: 1) Immunomodulatory drug initiators - patients initiating an immunomodulatory prescription ±60 days from index date; 2) Immunomodulatory drug prevalent users - patients receiving their first immunomodulatory drug prescription >60 days before the index date with at least one prescription within ±60 days of index date; and 3) Immunomodulatory non-users - patients receiving pegloticase without concomitant IMM drugs...

BACKGROUND: Social determinants of health (SDoH) likely contribute to outcome disparities in lupus nephritis (LN). Understanding the overall burden and contribution of each domain could guide future health-equity focused interventions to improve outcomes and reduce disparities in LN. Objectives of this meta-analysis were to: 1) determine the association of overall SDoH and specific SDoH domains on LN outcomes, and 2) develop a framework for the multidimensional impact of SDoH on LN outcomes...

OBJECTIVE: Giant cell arteritis (GCA) is characterized by granulomatous inflammation of the medium and large-sized arteries accompanied by remodeling of the vessel wall. Fibroblast activation protein alpha (FAP) is a serine protease which promotes both inflammation and fibrosis. Here we investigated the plasma levels and vascular expression of FAP in GCA. METHODS: Plasma FAP levels were measured with ELISA in treatment-naive GCA (n=60) and polymyalgia rheumatica (PMR, n=63) patients (compared to age- and sex-matched healthy controls (HC), n=42) and during follow-up, including treatment free remission (TFR)...

OBJECTIVES: To determine cervical cancer screening rates and factors associated with decreased cervical cancer screening in women with systemic lupus erythematosus (SLE). METHODS: We conducted a cross-sectional study that enrolled consecutive women (aged 21-64) with SLE. We collected demographics, clinical characteristics, constructs of the Health Beliefs Model (HBM) (i.e., susceptibility, severity, barriers, benefits, cues to action, and self-efficacy), and self-reported cervical cancer screening (confirmed with the electronic medical record)...

OBJECTIVE: To determine the prevalence of baseline risk factors for cardiovascular outcomes and cancer among commercially insured rheumatoid arthritis (RA) patients during their first dispensed treatment for either TNFi or JAKi. METHODS: Patients with RA from 8/16/2019-3/31/2022 were identified in the Merative MarketScan® Commercial and Medicare databases. The first dispensed TNFi or JAKi was the index date and baseline risk factors were assessed among patients continuously eligible for 12-months pre-index...

OBJECTIVE: Facilitated self-management interventions have the potential to enhance resilience and well-being. We examined whether resilience is a mediator of improving physical and psychological symptoms for people with systemic sclerosis (SSc) who participated in a 12-week online peer-led symptom management intervention. METHODS: We conducted a secondary data analysis from a randomized control trial comparing a peer health coached intervention to a waitlist control...

BACKGROUND: We studied the performance of integrated Raman Polarized light Microscopy (iRPolM) for the identification of calcium pyrophosphate (CPP) associated arthritis (CPPD) METHODS: This is a diagnostic accuracy study including 400 consecutive synovial fluid samples from a single hospital in the Netherlands. Accuracy measures were calculated against polarized light microscopy (PLM) and the 2023 ACR/EULAR criteria set for CPPD. RESULTS: The interrater reliability between iRPolM and the 2023 ACR/EULAR criteria set for CPPD was strong (k = 0...

OBJECTIVE: The Objective was to determine the diagnostic accuracy of thoracic ultrasound (TUS) for detecting (ILD) in rheumatoid arthritis (RA) with respiratory symptoms. METHODS: Individuals with RA visiting Rheumatological outpatient clinics in the Region of Southern Denmark were systematically screened for dyspnoea, cough, recurrent pneumonia, prior severe pneumonia or a chest X-ray indicating interstitial abnormalities. Eighty participants with a positive screening were consecutively included...

OBJECTIVES: Quit Connect (QC), our specialty clinic smoking cessation intervention, supports clinic staff to check, advise, and connect willing patients to a state quit line or class. QC improved tobacco screening and quit line referrals 26-fold in a predominantly White academic healthcare system population. Implementing QC includes education, electronic health record (EHR) reminders, and periodic audit feedback. This study tested QC's feasibility and impact in a safety-net rheumatology clinic with a predominantly Black population...

OBJECTIVE: We aim to compare drug effectiveness and persistence between reference etanercept (ETN) and ETN biosimilar SB4 in psoriatic arthritis (PsA) patients naïve to ETN and to investigate drug effectiveness and persistence in those undergoing mandatory non-medical switch from ETN to SB4. METHODS: Retrospective comparative database study including 1138 PsA patients treated with ETN or SB4 (years 1999-2021) in Norway. Disease activity score in 28 joints (DAS28) and drug persistence were compared between unmatched ETN (n=644) and SB4 (n=252) cohorts and in matched analyses (n=144, both cohorts) at baseline using propensity score (PS) to adjust for confounders...

BACKGROUND: Systemic sclerosis (SSc) is a heterogeneous disease, characterized by variable tissue and vascular fibrosis in the context of autoimmune activation. The C-C Motif Chemokine Ligand 24 (CCL24 or Eotaxin2) has been shown to promote microangiopathic, pro-inflammatory, and pro-fibrotic processes in preclinical models of SSc. Here we study serum CCL24 levels in a real-life cohort of SSc patients, to determine its distribution across disease features and its value in predicting disease progression and related mortality...

Two-sample MR analyses were performed utilizing the inverse variance weighted (IVW) technique...

OBJECTIVE: Although hand synovitis is prevalent in the older population, the aetiology remains unclear. Hyperuricemia, a modifiable metabolic disorder, may serve as an underlying mechanism of hand synovitis, but little is known about their relationship. We assessed the association between hyperuricemia and hand synovitis in a large population-based sample. METHODS: We performed a cross-sectional study in Longshan County, Hunan Province, China. Hyperuricemia was defined as a serum urate >420 μmol/L in men and >360 μmol/L in women...

BACKGROUND: Neuroinflammatory adverse events have been observed among new users of tumor necrosis factor (TNF) inhibitors. No studies to date have compared the real-world risk of TNFs to other new users of biologic or targeted synthetic disease modifying antirheumatic drugs (b/tsDMARD). The objective of this study is to describe the risk of neuroinflammatory disease after initiation b/tsDMARDs. METHODS: This new-user comparative effectiveness cohort study utilized a large US-based electronic health-records database to describe the unadjusted incidence of neuroinflammatory adverse events over a 3-year period...

OBJECTIVE: We explored the trend in prevalence of hyperuricemia and metabolic syndrome in US populations and investigated associations between components of metabolic syndrome and hyperuricemia by race. METHODS: We analyzed data from the four most recent National Health and Nutrition Examination Survey (NHANES) cycles (2011 to March 2020), comprising 10,175 participants. Hyperuricemia is defined as serum urate >7.0 mg/dL (men) or >5.7 mg/dL (women), following the NHANES-III guideline...

OBJECTIVE: Musculoskeletal ultrasound (MSUS) is widely used in adult rheumatology practice for diagnosis of arthritis and procedural guidance, however it is not yet common practice in pediatric rheumatology. MSUS is advantageous to the pediatric population as it lacks radiation and eliminates need for sedation. This study aims to assess interest in, access to, and barriers to MSUS training in pediatric rheumatology fellowship programs in North America. METHODS: A survey was developed by pediatric rheumatology providers with experience in medical and/or MSUS education, and distributed via REDCap® anonymously in March 2022 (Supplementary Material)...
