Identification and validation of susceptibility modules and hub genes in polyarticular juvenile idiopathic arthritis using WGCNA and machine learning.

Background: Juvenile idiopathic arthritis (JIA), superseding juvenile rheumatoid arthritis (JRA), is a chronic autoimmune disease affecting children and characterized by various types of childhood arthritis. JIA manifests clinically with joint inflammation, swelling, pain, and limited mobility, potentially leading to long-term joint damage if untreated. This study aimed to identify genes associated with the progression and prognosis of JIA polyarticular to enhance clinical diagnosis and treatment.

New onset heart failure in adolescents with inflammatory joint disease treated with TNF-α inhibitors: a case-based review.

The safety of tumor necrosis factor (TNF) inhibitors has been demonstrated for over two decades. However, their effects on cardiovascular function in patients with rheumatic diseases remain controversial, and conclusions are additionally hampered by the cardiovascular complications inherent in such diseases. We present two 15-year-old patients diagnosed with ankylosing spondylitis and juvenile idiopathic arthritis classified as polyarthritis with positive rheumatoid factor, respectively.

Fetal Growth Associated with Maternal Rheumatoid Arthritis and Juvenile Idiopathic Arthritis.

Patients with rheumatoid arthritis (RA) and juvenile idiopathic arthritis (JIA) are at a twice-higher risk of developing adverse pregnancy outcomes, such as preterm births and infants with a low birth weight. We aimed to evaluate fetal growth among patients with and without rheumatoid arthritis and juvenile idiopathic arthritis (RA and JIA). We conducted a population-based cohort study in Denmark from 2008-2018, which included 503,491 singleton pregnancies.

Comprehensive Characterization of Th2/Th17 Cells-Related Gene in Systemic Juvenile Rheumatoid Arthritis: Evidence from Mendelian Randomization and Transcriptome Data Using Multiple Machine Learning Approaches.

Background: Growing research has demonstrated that alterations in Th2 and Th17 cell composition were linked to systemic juvenile rheumatoid arthritis (sJRA). Nevertheless, whether these associations indicate a causal link remains unclear, and the potential effects of Th2/Th17-related molecules have not been clarified.

Methods: Mendelian randomization (MR) alongside transcriptome examination was implemented to ascertain the links between the Th2/Th17 cells and sJRA.

Causal Effects of Rheumatoid Arthritis, Ankylosing Spondylitis, Juvenile Idiopathic Arthritis on Psoriasis: A Mendelian Randomization Study.

Background: It is well-documented that rheumatoid arthritis (RA), ankylosing spondylitis (AS), and juvenile idiopathic arthritis (JIA) often exhibit skin manifestations, with psoriasis typically occurring around the time of diagnosis. Thus, it is essential to investigate the potential causal relationship between these forms of arthritis and psoriasis.

Methods: The OpenGWAS provided traitIDs for exposure factors (RA (bbj-A-74), AS (ebi-A-GCST005529), and JIA (finn-b-JUVEN-ARTHR)) and outcome (psoriasis, finn-b-L12-PSORIASIS).

Anti-lipoprotein lipase antibodies: A review.

Background: Dyslipidemia is described in several autoimmune conditions. Lipoprotein lipase (LPL) is responsible for triglyceride breakdown. Anti-LPL antibodies have been described.

[Not Available].

Aims: To analyse the prescription of biologics (bDMARDs) in chronic inflammatory rheumatic diseases (CIRD) from Tunisian National Health Insurance (CNAM) data and to estimate their direct costs and associated factors.

Methods: One hundred and nine consecutive patients who received at least one bDMARDs during a six-month period from January to June 2022 were analysed. Clinical and therapeutic parameters as well as data related to the choice of bDMARDs were identified.

Role of Synovectomy in Rheumatoid Hand and Wrist.

Synovectomy refers to the removal of all or part of the hypertrophied soft tissue membrane on the inside of the joint capsule or around tendons. Historically, this was typically performed for rheumatoid arthritis and other inflammatory conditions of the hand, but following the development of more advanced medical treatments, the role of synovectomy has come into question. In this article, the authors outline the biologic basis for synovectomy and then consider its present and future role in the management of joint and tendon disease, followed by what further research is needed.

Treatment of Juvenile Idiopathic Arthritis.

This review outlines the natural history, diagnosis, and management of juvenile idiopathic arthritis involving the hand and wrist. The discussion of management considers both nonoperative and surgical management to preserve functionality and mitigate long-term articular damage in children and adolescents. The review describes the current literature and identifies areas for further study.

Challenges and Long-Term Outcomes of Cementless Total Hip Arthroplasty in Patients Under 30: A 24-Year Follow-Up Study with a Minimum 8-Year Follow-Up, Focused on Developmental Dysplasia of the Hip.

Total hip arthroplasty (THA) is a well-established and effective treatment for advanced osteoarthritis (OA) of the hip joint. While commonly performed in older patients, THA is increasingly used in younger individuals, especially in cases of secondary coxarthrosis. Technological advances have led to the development of specialized implants, which allow surgeons to address severe post-inflammatory or dysplastic deformities.

HLA-DRB1*01 predicts treatment outcome in juvenile idiopathic arthritis: A retrospective-prospective cohort study.

Juvenile idiopathic arthritis (JIA) is the most common chronic inflammatory autoimmune disease in childhood, significantly contributing to both short- and long-term disability. While certain human leukocyte antigen (HLA) class II alleles are known to be associated with specific subgroups of JIA, emerging evidence suggests a strong correlation between these alleles and treatment response. This study involved 143 JIA patients diagnosed according to International League of Associations for Rheumatology criteria.

Differential type I and type III interferon expression profiles in rheumatoid and juvenile idiopathic arthritis.

Background: The role of type I and type III interferons (IFNs) in rheumatoid arthritis (RA) and juvenile idiopathic arthritis (JIA) is still poorly understood. The objective of this study was to examine the hypothesis that IFN expression profiles in the peripheral blood differ between subsets of arthritic subjects. Multiple type I and type III IFNs were examined in patients with RA and JIA, as well as among subtypes of JIA.
