Purpose: To provide an overview of recent studies on pathogenesis, diagnosis, and management of juvenile spondyloarthritis (JSpA).
Recent Findings: Recent studies show differences in gut microbiome in patients with JSpA in comparison to healthy controls. There is increased recognition of the impact of the innate immune system on disease pathology. Normative reference on MRI of sacroiliac (SI) joints in children is now available. However, there is significant variability in interpretation of MRI of SI joints in children and a need for standardization. NSAIDs, physical therapy, and Tumor Necrosis Factor Inhibitors (TNFi) remain the mainstay of management for patients with JIA who have polyarthritis, sacroiliitis, and/or enthesitis as per recent ACR guidelines. Newer therapeutic options beyond TNFi are needed to manage patients who fail TNFi. This review highlights some of the recent advances in our knowledge of JSpA pathophysiology, diagnosis, and treatment. It also identifies areas in need of further research and standardization to improve our understanding and outcomes in JSpA.

Sarcopenia is a disease characterized by decreasing muscle mass and strength or performance. The prevalence of sarcopenia in rheumatic diseases has been evaluated in single diseases using various diagnostic approaches, generating conflicting data. The study aims to investigate sarcopenia prevalence in young adults with inflammatory arthritis (IA) and to detect factors associated with low muscle mass and strength.

Objectives: This study aimed to evaluate the rate of successful transitions, identify factors associated with early versus late transitions, and diagnosis and treatment changes after transition into adult rheumatology.
Patients And Methods: In this retrospective study, patients with childhood-onset rheumatic diseases who transitioned from pediatric to adult rheumatology care between January 2013 and January 2023 were screened for a successful transition. Successful transitions were defined as maintaining annual visits to the adult rheumatology clinic after transition.

Enthesitis-related arthritis (ERA), a distinct subtype of juvenile idiopathic arthritis (JIA) related to HLA-B27 and peripheral and axial involvement, presents with insidious onset of arthritis and/or enthesitis. However, there is a lack of data concerning axial new bone formation in patients transitioning into adulthood. To evaluate the axial radiographic structural damage (axRxSD), encompassing the sacroiliac joints (SIJ), hips, and spine, in ERA patients across various age groups.

Background: People with inflammatory arthritis are at risk for poor COVID-19 outcomes. Little is known about the impact of long COVID on disease activity, disability, and quality of life in this population.
Methods: We included participants with rheumatoid arthritis, psoriatic arthritis, juvenile idiopathic arthritis, or axial spondyloarthritis from RheumCARD, a prospective cohort study of people with rheumatic disease with and without prior COVID-19.
Physician's global assessment of disease activity in juvenile idiopathic arthritis: consensus-based recommendations from an international task force.

IRCCS Istituto Giannina Gaslini, Genoa, Italy; Università degli Studi di Genova, Genova, Italy.
Objectives: To develop consensus-based recommendations for physician's global assessment of disease activity (PhGA) scoring and to standardise definitions of disease activity.
Methods: An international task force of 34 members was assembled, and recommendations were developed in 3 phases: (1) 2 preliminary surveys of paediatric rheumatologists and a literature review; (2) 14 videoconference meetings, informed by multicriteria decision analysis and formal anonymous voting; and (3) a 2-day in-person consensus conference using structured nominal group technique discussions and formal voting. The threshold for achieving consensus was ≥78% of voting task force members.
