Summary: This study identified rare coding variants in JIA patients using RNA-seq data, including some reported causal variants. These variants were partially replicated in polyarticular patients and shared common variants with genes associated with autoimmune diseases. Genes related to immune pathways were enriched for rare coding variants and differentially expressed genes.

Summary: This study aimed to evaluate the efficacy and potential adverse effects of JAKi in patients with systemic juvenile idiopathic arthritis (SJIA). The results showed that JAKi may be an alternative or adjuvant agent for patients with persistently active disease, glucocorticoid-related adverse reactions, or SJIA-MAS.

Summary: The study suggests that intercellular communication mediated by extracellular vesicles plays an important role in the pathogenesis of systemic juvenile idiopathic arthritis. The number and cellular sources of extracellular vesicles differ between the active and inactive states of the disease and healthy controls.

Summary: Systemic juvenile idiopathic arthritis (sJIA) is a disease characterized by severe systemic inflammation and arthritis. It poses challenges to rheumatologists treating pediatric and adult patients worldwide. Although treatment plans exist for classic sJIA, there is still a lack of clear treatment approaches for early sJIA without arthritis and complicated sJIA.

Summary: Neutrophils play a crucial role in the innate immune system, using both oxidative and non-oxidative defense mechanisms to eradicate pathogens, and also act as decision shaping cells guiding other leukocytes for immune responses. The development and release of neutrophils are tightly regulated under both homeostatic and emergency conditions.

Summary: This review focuses on the treatment options and potential future therapeutics for systemic juvenile idiopathic arthritis (SJIA). Recent advancements in targeted therapies have improved patient outcomes, but there are still subsets of patients with refractory disease and severe complications.

Summary: Psoriatic arthritis is a chronic autoimmune condition with unique cutaneous manifestations. Tumor necrosis factor inhibitors, such as golimumab, have become a hallmark treatment option. Multiple studies have shown the efficacy of golimumab in both juvenile and adult-onset psoriatic arthritis.

Summary: This study compared the prevalence of multiple coexisting autoimmune diseases in patients with juvenile idiopathic arthritis (JIA) and a general paediatric (GP) patient population. Results showed that JIA patients had a higher prevalence of a large number of coexisting autoimmune diseases compared to the GP population, with 53.8% of the evaluated conditions having significantly higher prevalence in the JIA cohort.

Summary: This study explores the shared gene signatures and potential molecular mechanisms of polyarticular juvenile idiopathic arthritis (pJIA) and autoimmune uveitis (AU) through data analysis and functional enrichment analysis. Neutrophil degranulation may be considered a shared pathogenic mechanism, and the roles of ARID1A gene and hsa-miR-146a are worthy of further study. Additionally, periodic inspection of kidney function is also important.

Summary: This study compared MRI findings between patients clinically suspected of Juvenile Idiopathic Arthritis (JIA) and patients with ankle arthralgia of unknown cause. The results showed that inflammatory features were observed on MRI, with tenosynovitis being significantly more common in JIA patients. However, the MRI summarized score did not effectively differentiate between JIA and non-JIA patients.

Summary: Early diagnosis is crucial for reducing long-term disability in JIA patients. This study evaluated salivary gland function in JIA patients, finding differences between oligoarticular and polyarticular subtypes. Impairment of salivary gland function may serve as a risk indicator for JIA1.

Summary: This study used real-world data to evaluate the effectiveness and safety of canakinumab in Italian patients with sJIA. The results showed that canakinumab was effective in treating sJIA and had no serious adverse events. The history of MAS and higher number of active joints were associated with poorer treatment outcomes.

Summary: This study aimed to investigate the association between systemic antibiotics in prenatal and early life and the risk of JIA. The results showed an association between antibiotic exposure during 0-24 months and JIA, while there was no association with prenatal antibiotic exposure. This novel observation suggests that early-life antibiotic exposure may be an independent risk factor for JIA.

Summary: This study investigated the effect of methotrexate (MTX) therapy on new-onset uveitis in patients with biological-naive juvenile idiopathic arthritis (JIA). The results showed that MTX was associated with a significantly reduced new-onset uveitis rate in patients with JIA. Clinicians should consider early initiation of MTX in high-risk patients and increase ophthalmologic screening after MTX discontinuation.

Summary: This study validated the use of a urinary protein panel to predict active renal involvement in SLE patients and potentially predict response to rituximab treatment. The levels of certain proteins in urine were significantly higher in SLE patients with active LN, supporting the potential of these biomarkers in non-invasive routine testing for SLE patients.

Summary: Early treatment and frequent screening are crucial for controlling JIA-associated uveitis, which poses a significant risk for serious complications. The identification of specific risk factors for JIA-associated uveitis is a key focus of research as our understanding of pathogenic drivers is still incomplete. Genomic, transcriptomic, and proteomic factors have been identified as potential risk factors, and therapeutic strategies are being discussed.

Summary: Chronic non-bacterial osteomyelitis (CNO) is an autoinflammatory bone disease that commonly affects children and adolescents, causing significant pain and bone damage. The lack of diagnostic criteria and biomarkers, incomplete understanding of molecular pathophysiology, and absence of evidence from randomized and controlled trials make diagnosis and treatment challenging.

Summary: This study aimed to investigate whether 3% NaCl triggers inflammation in human macrophages and identify the molecular mechanisms involved. The results showed that 3% NaCl induces inflammatory responses in human macrophages through NLRP1 and inflammasome assembly. Targeting inflammation in addition to inhalation with hypertonic saline may benefit patients with inflammatory airway disease.
