Background: Variations in the use of healthcare resources can result in differences in the outcome of rheumatoid arthritis (RA). The emAR study was developed to determine variations in the management of socio-sanitary resources, including drugs use, in patients with this disorder.
Patients And Method: The clinical records of 1,379 patients, randomly selected among all RA patients attended in Spanish hospitals, were reviewed. Information about prescription of disease modifying anti-rheumatic drugs (DMARD), non-steroidal anti-inflammatory drugs (NSAID), corticosteroids, analgesics, gastric protectors and drugs for osteoporosis was collected. In addition, socio-demographic- and disease-related information, as well as data from hospitals, medical units and responsible physicians were also obtained in each patient.
Results: There was a high level of DMARD and NSAID prescription that was associated with patient or disease characteristics. Treatment with corticosteroids, as well as with the remaining drugs, showed a substantial regional variability, which may be related to physician-associated variables as well as to patient- and disease-associated characteristics.
Conclusions: Variability in the management of therapeutic resources in RA patients mainly depends on the characteristics of the patient or the disease. There is also a variation that is influenced by physician's characteristics; in some cases, the available scientific evidence may not support this variability.

Introduction: Ozoralizumab (OZR) is a novel tumor necrosis factor (TNF) inhibitor that was launched in Japan for treating patients with rheumatoid arthritis (RA) who have had an inadequate response to existing therapies. This post-hoc analysis aimed to compare the efficacy of OZR administered without methotrexate (MTX) with placebo or OZR administration in combination with MTX.
Methods: We analyzed the OZR group (30 mg) in the NATSUZORA trial (non-MTX, open trial) (OZR group; n = 94) and the placebo group (MTX group; n = 75) and the 30-mg OZR group (OZR + MTX group; n = 152) in the OHZORA trial (combined MTX, double-blind trial), and the covariates were adjusted by propensity score matching.
Cardiovascular, cancer, and infection risks of Janus kinase inhibitors in rheumatoid arthritis and ulcerative colitis: A nationwide cohort study.
J Intern Med
January 2025
School of Pharmacy, Sungkyunkwan University, Suwon, South Korea.
Background: Evolving evidence suggests that patients undergoing treatment with Janus kinase inhibitors (JAKi) may face an increased risk of cardiovascular events, malignancies, and serious infections.
Objectives: We assessed cardiovascular, malignancy, and serious infection risks associated with JAKi use compared to tumor necrosis factor inhibitor (TNFi) use, which served as the active comparator, in patients with rheumatoid arthritis (RA) or ulcerative colitis (UC).
Methods: This study emulated a target trial using South Korea's nationwide claims database (2013-2023).
Psychometric Properties of the Chinese Version of the Arthritis Self-Care Behaviors Scale.
Int J Rheum Dis
January 2025
School of Nursing, Peking University, Beijing, People's Republic of China.
Background: In Chinese intervention studies, the lack of specific self-care scales based on the functional characteristics of Rheumatoid arthritis (RA) patients has caused patients and researchers to spend a great deal of time completing multiple related scales during the research work. Therefore, the arthritis Self-Care Behaviors Scale (SCBS) was developed to evaluate the self-care behavior of patients with arthritis.
Objective: The objectives of this study were to translate the SCBS into Chinese and test its psychometric properties in Chinese patients with RA.
This 30-color panel was developed to enable the enumeration and purification of distinct circulating immune cell subsets implicated in the pathogenesis of systemic autoimmune diseases including rheumatoid arthritis (RA), systemic lupus erythematosus (SLE), systemic sclerosis (SSc; scleroderma), Sjögren's disease (SjD), idiopathic inflammatory myopathy (IIM), and others. While designed for application to peripheral blood mononuclear cells, the inclusion of CD45 coupled with the ability to extract cellular autofluorescence spectral signatures enables the application of this panel to other tissue types. Of the 30 total markers, this panel employs 18 markers to profile T cell subsets consisting of different memory subsets and T helper polarities, > 10 markers to profile B cell subsets including double-negative B cells, and a total of 8 lineage markers to identify immune lineages including monocyte and natural killer cell subsets, conventional dendritic cells, plasmacytoid dendritic cells, and basophils.
