This systematic review and meta-analysis assess the efficacy and safety of rituximab (RTX) in treating idiopathic inflammatory myositis (IIM).

Drug persistence is a crucial measure of long-term efficacy, safety, and patient satisfaction. Lack of persistence can increase healthcare costs and morbidity and mortality rates. This review aimed to consolidate available data on drug persistence for various biological treatments used as the primary intervention for psoriatic arthritis and identify factors associated with nonpersistence. Reports indicate variable 1-year persistence rates for biologic therapies, ranging from 37% to 73%. Specifically, tumor necrosis factor inhibitors have shown fluctuating 1-year persistence rates ranging from 32% to 85%. IL-12/23 and IL-23 inhibitors demonstrate persistence rates of 25% to 89%, whereas data for IL-17 and JAK inhibitors are more limited, ranging from 51% to 77%. Factors such as female sex and a higher burden of comorbidities have been associated with an increased risk of nonpersistence, although evidence regarding other factors remains scarce. The significant variability in reported persistence rates may be attributed to differences in treatment gaps and methodologies across studies. Addressing and mitigating the factors leading to nonpersistence is essential for improving treatment outcomes in psoriatic arthritis.

Inflammatory arthritis frequently affects patients with systemic sclerosis (SSc) but musculoskeletal corticosteroid (MSKC) injections are often avoided due to concerns of scleroderma renal crisis (SRC). This study investigated the incidence of SRC following MSKC injections.

Sarcoidosis is a multisystem autoimmune disease that can result in significant morbidity and mortality. This study aims to identify factors associated with in-hospital death for sarcoid patients on a national level.

Musculoskeletal ultrasound (MSUS) is increasingly used to evaluate pediatric inflammatory arthritis. This study aimed to explore the relationship between MSUS findings with medication modifications in patients with juvenile idiopathic arthritis (JIA) and clinical disease activity measurements (clinical Juvenile Arthritis Disease Activity Score [cJADAS-10], active joint count [AJC], patient/parent global assessment [PPGA], and physician global assessment [PGA]).

Wong-type dermatomyositis (WTDM) was first formally discussed in the literature in 1969 by Dr. K.O. Wong. This rare variant of dermatomyositis (DM) is characterized by overlapping features of both classic DM and the cutaneous features of pityriasis rubra pilaris. Since 1969, few cases of WTDM have been published in the literature likely due to the rarity of this condition or lack of recognition by clinicians. This narrative review presents the current published English literature on WTDM, analyzing its clinical presentation, diagnostic testing, and treatments along with a comparison to classic DM. Given the overlap of features of both diseases and patients experiencing a better response to classic DM treatments, our results suggest that WTDM is a rare subtype of DM rather than simply an overlap of pityriasis rubra pilaris and DM presenting in 1 patient. We suggest that clinicians evaluate WTDM patients with very thorough histories, physical examinations, histopathology, and appropriate serological studies and monitor closely for systemic symptoms and development of malignancy. WTDM should be treated using conventional treatments for classical DM. Further studies are needed to understand the pathogenesis of WTDM including more specific and distinguishing autoantibody profiles from classical DM, as well as long-term clinical course of WTDM for best management, including recently available biological treatments.

Behçet disease (BD) has heterogeneous presentations, mainly mucocutaneous, vascular, and ocular manifestations. The mechanisms associated with different phenotypes have not been clarified. We aimed to investigate the expression of innate and adaptive immunity-related cytokines in these 3 main BD phenotypes in active and untreated states and remission after treatment to be able to develop a cytokine-based treatment algorithm.

We evaluated a behaviorally designed intervention utilizing gamification and social support to improve physical activity and reduce symptoms in patients with osteoarthritis of the knee (KOA).

Pulmonary arterial involvement (PAI) is one of the most common causes of mortality in Behçet's disease (BD). In this study, we aimed to evaluate the clinical features, course, and recurrence risk factors of BD-associated PAI.

The advent of genome-wide sequencing and large-scale genetic epidemiological studies has led to numerous opportunities for the application of genetics in clinical medicine. Leveraging this information toward the formation of clinically useful tools has been an ongoing research goal in this area. A genetic risk score (GRS) is a measure that attempts to estimate the cumulative contribution of established genetic risk factors toward an outcome of interest, taking into account the cumulative risk that each of these individual genetic risk factors conveys. The purpose of this perspective is to provide a systematic framework to evaluate a GRS for clinical application.

Shared decision-making (SDM) is a principle of humanistic, patient-centered health care within the field of rheumatology. However, clear communication between patients and their clinicians regarding the benefits and risks of immunomodulators may be challenging in a clinical setting. The design-thinking process is a human-centered approach to quality improvement that can help to identify insights to uphold high-quality communication.

Diagnosis of periprosthetic joint infection (PJI) in patients with inflammatory arthritis (IA) is challenging, as features of IA flares can mimic infection. We aimed to cross-sectionally determine if the optimal tests to diagnose PJI in osteoarthritis were present in patients with IA flares.
