Background: Altered subchondral bone mineral density (BMD) may be a possible contributor to osteoarthritis (OA) pain. We evaluated the relation of compartment-specific proximal tibial BMD, at varying depths beneath the subchondral surface, to knee pain.
Methods: Multicenter Osteoarthritis (MOST) study participants with knee CTs were included.
Objectives: To assess the comparative safety of tumor necrosis factor inhibitor (TNFi), non-TNFi, and Janus kinase inhibitor (JAKi) biologic or targeted synthetic disease-modifying anti-rheumatic drugs (b/tsDMARD) in patients with rheumatoid arthritis (RA) for the risk of major adverse cardiovascular events (MACE) using US administrative claims data.
Methods: We performed a cohort study using MerativeTM Marketscan® Research Databases (2012-2021) of individuals aged 18-64 years with RA initiating b/tsDMARD treatment. We used Cox proportional hazard models to estimate hazard ratios (HR) and 95% CI for developing MACE within 2 years of b/tsDMARD initiation, adjusting for potential confounders.
Background: Preventing worsening osteoarthritis (OA) in persons with early OA is a major treatment goal. We evaluated if different early OA definitions yielded enough cases of worsening OA within 2-5 years to make trial testing treatments feasible.
Methods: We assessed different definitions of early OA using data from Multicenter Osteoarthritis (MOST) Study participants who were followed up longitudinally.
Background: We developed a United States-based real-world data resource to better understand the continued impact of the coronavirus disease 2019 (COVID-19) pandemic on immunocompromised patients, who are typically underrepresented in prospective studies and clinical trials.
Methods: The COVID-19 Real World Data infrastructure (CRWDi) was created by linking and harmonizing de-identified HealthVerity medical and pharmacy claims data from 1 December 2018 to 31 December 2023, with severe acute respiratory syndrome coronavirus 2 virologic and serologic laboratory data from major commercial laboratories and Northwell Health; COVID-19 vaccination data; and, for patients with cancer, 2010 to 2021 National Cancer Institute Surveillance, Epidemiology, and End Results registry data.
Results: The CRWDi contains 4 cohorts: patients with cancer; patients with rheumatic diseases receiving pharmacotherapy; noncancer solid organ and hematopoietic stem cell transplant recipients; and people from the general population including adults and pediatric patients.
Objective: People with axial spondyloarthritis (axSpA) have increased fracture risk relative to the general population, possibly related to those with chronic inflammation. We assessed the impact of treatment with receiving tumor necrosis factor inhibitors (TNFis) and nonbiologic conventional synthetic disease-modifying antirheumatic drugs (csDMARDs) on hip and spine fractures in patients with axSpA, relative to receiving nonsteroidal anti-inflammatory drugs (NSAIDs).
Methods: We conducted a nested case-control study using 2006 to 2021 data from the Merative MarketScan Database.
Importance: The Oral Rheumatoid Arthritis Trial Surveillance demonstrated an increased cancer risk among patients with rheumatoid arthritis (RA) taking tofacitinib compared with those taking tumor necrosis factor inhibitors (TNFis). Although international cohort studies have compared cancer outcomes between TNFis, non-TNFi drugs, and Janus kinase inhibitor (JAKis), their generalizability to US patients with RA is limited.
Objective: To assess the comparative safety of TNFis, non-TNFi drugs, and JAKis among US patients with RA (ie, the cancer risk associated with the use of these drugs among these patients).
Objective: Radiographic axial spondyloarthritis (r-axSpA) has a 7-year average diagnostic delay. Although the effects of sex or gender on time to diagnosis have been evaluated, the role of social determinants of health remains understudied. We assessed whether time from initial clinical documentation of r-axSpA symptoms to r-axSpA diagnosis (diagnostic delay) varies based on sex, race, ethnicity, and/or the presence of social needs.

However, whether disparities in RA treatment selection and outcomes differ by urban versus rural residence, independent of race, have not been studied. Our objective was to evaluate whether biologic disease-modifying antirheumatic drug (bDMARD) initiation after methotrexate administration differs by rural versus urban residence among veterans with RA.

We examined the association between opioid use and healthcare utilization and costs among patients with psoriatic arthritis (PsA) and ankylosing spondylitis (AS).
Methods: We included adults with PsA or AS enrolled in the FORWARD registry, with ≥ 1 completed disease activity or disability questionnaire between 2010 and 2019.
Background: Whether tumor necrosis factor inhibitor (TNFi) use is cardioprotective among individuals with radiographic axial spondyloarthritis (r-axSpA), who have heightened cardiovascular (CV) risk, is unclear. We tested the association of TNFi use with incident CV outcomes in r-axSpA.
Methods: We identified a r-axSpA cohort within a Veterans Affairs database between 2002 and 2019 using novel phenotyping methods and secondarily using ICD codes.
Objective: Intra-articular (IA) mineralization may contribute to osteoarthritis (OA) structural progression. We studied the association of IA mineralization on knee computed tomography (CT) with cartilage damage worsening on knee magnetic resonance imaging (MRI), with a focus on location- and tissue-specific effects.
Methods: Participants from the Multicenter Osteoarthritis Study with knee CT and MRI scans were included.
Background: Targeted biological immunotherapies have been highly effective in controlling skin disease in patients with psoriasis, but whether therapy delays progression to inflammatory arthritis is unclear. The aim of this study was to compare the time to incident inflammatory arthritis among patients newly receiving biological therapies for psoriasis.
Methods: In this retrospective cohort study, we obtained data on a national sample of patients in the USA from the electronic health records database of the US-based TriNetX network.

Objectives: To examine the association of multimorbidity phenotypes at baseline with disease activity and functional status over time in ankylosing spondylitis (AS).
Methods: Patient-reported AS morbidities (comorbidities, N = 28 and extra-musculoskeletal manifestations, EMMs, N = 3) within 3 years of enrollment with a prevalence ≥1 %, were included from the Prospective Study of Outcomes in Ankylosing Spondylitis (PSOAS) cohort. We defined multimorbidity as ≥2 morbidities (MM2+) and substantial multimorbidity as ≥5 morbidities (MM5+).
Janus kinase inhibitors were recently approved for treatment of axial spondyloarthritis following clinical trials demonstrating benefit for symptom control. Upadacitinib treatment resulted in Assessment of SpondyloArthritis International Society 40 response improvement (defined as at least 40% improvement and an absolute improvement in global assessment of disease activity, patient assessment of back pain and other indices) in 45-52% of trial participants with axial spondyloarthritis. We review the data for efficacy and safety of upadacitinib in this patient population.

Although studies have investigated risk factors linked to severe COVID-19 among unvaccinated people with rheumatic diseases (RDs), we know less about whether these factors changed as the pandemic progressed. We aimed to identify risk factors associated with severe COVID-19 in unvaccinated individuals in different pandemic epochs corresponding to major variants of concern.
View Article and Find Full Text PDFObjective: The COVID-19 pandemic resulted in rapid adoption of telemedicine in rheumatology. We described perspectives of patients with rheumatic diseases related to telemedicine use.
Methods: An anonymous online survey for people with rheumatic diseases was launched in January 2021.
Objective: Intra-articular (IA) calcium crystal deposition is common in knee osteoarthritis (OA), but of unclear significance. It is possible that low-grade, crystal-related inflammation may contribute to knee pain. We examined the longitudinal relation of computed tomography (CT)-detected IA mineralization to the development of knee pain.

Objective: There is an increased risk of fracture in individuals with ankylosing spondylitis (AS) compared to the general population, possibly due to systemic inflammatory effects. The use of tumor necrosis factor inhibitors (TNFi) may reduce fracture risk by inhibiting inflammation. We assessed fracture rates in AS versus non-AS comparators and whether these rates have changed since the introduction of TNFi.
