Juvenile RA treatment

Schiotis Re, Buzoianu Ad, Mureșanu Df, Suciu S
Targeting the pathogenic pathway of chronic inflammation represents an unmet challenge for controlling disease activity, preventing functional disability, and maintaining an adequate quality of life in patients with rheumatic diseases. Abatacept, a novel molecule that inhibits co-stimulation signal, induces an inhibitory effect on the T-cells. This will further interfere with the activity of several cell lines, leading to the normalization of the immune response. In the latest years, abatacept has been extensively investigated in studies of rheumatoid arthritis for which it was recently approved as a second line biologic treatment in Romania...

BACKGROUND: Diseases associated with human cartilage, including rheumatoid arthritis (RA) and osteoarthritis (OA) have manifested age, mechanical stresses and inflammation as the leading risk factors. Although inflammatory processes are known to be upregulated upon aging, we sought to gain a molecular understanding of how aging affects the tissue-specific response to inflammation. In this report, we explored the role of cluster of differentiation 24 (CD24) in regulating differential inflammatory responses in juvenile and adult human chondrocytes...

Juvenile idiopathic arthritis (JIA) is the most common form of chronic rheumatic disease affecting children worldwide, with some features similar to adult rheumatoid arthritis (RA). In the present study, we aim at investigating novel markers that will allow in the future for tailored, more personalized treatment strategies. Hence, taking notice of several reports proving the role of local acidosis as a causal link between inflammatory diseases and related pain, and the involvement of several carbonic anhydrases (CA, EC 4...

Large sexual dimorphisms exist in the zebra finch song system. Masculinization may be mediated by both estradiol and expression of one or more Z-genes (males: ZZ; females: ZW). Roles of the Z-gene tyrosine kinase B (TrkB) in HVC in masculinizing both HVC and one of its targets the robust nucleus of the arcopallium (RA), were tested using siRNA administration in juvenile males at two ages (post-hatching days 15-17 or 25-27). Birds were euthanized 10 days later. Potential interactions or additive effects with estradiol were evaluated by treating males with the estrogen synthesis inhibitor fadrozole...

Perturbations in the vitamin A metabolism pathway could be a significant cause of male infertility, as well as a target toward the development of a male contraceptive, necessitating the need for a better understanding of how testicular retinoic acid (RA) concentrations are regulated. Quantitative analyses have recently demonstrated that RA is present in a pulsatile manner along testis tubules. However, it is unclear if the aldehyde dehydrogenase (ALDH) enzymes, which are responsible for RA synthesis, contribute to the regulation of these RA concentration gradients...

Rheumatoid arthritis (RA) is characterized by inflammatory synovitis and is mediated by several cytokines; this includes interleukin-6, whose receptor has been successfully targeted by the humanized monoclonal antibody tocilizumab. Intravenous tocilizumab (TCZ-IV) is registered for use in RA (alone or as combination therapy), systemic juvenile idiopathic arthritis and Castleman disease. Subcutaneous tocilizumab (TCZ-SC) is a desirable alternative to existing subcutaneous biological disease modifying antirheumatic drugs (bDMARDs) targeting tumor necrosis factor...

CONTEXT: Acquired generalized lipodystrophy (AGL) is associated with leptin deficiency as a result of adipose tissue loss and hypertriglyceridemia, insulin resistance, and hepatic steatosis. It may coexist with other autoimmune diseases such as Hashimoto's thyroiditis, rheumatoid arthritis, hemolytic anemia, and chronic active hepatitis. Metreleptin therapy has been shown to improve metabolic abnormalities in lipodystrophy, but the effect on AGL patients with active autoimmune disease is unknown...

There are only three cases in the literature that describe development of neurosarcoidosis in a patient who is on tumour necrosis factor α inhibitors. We describe a case of a 33-year-old woman with a history of juvenile rheumatoid arthritis and refractory uveitis (with previous treatment trials of adalimumab, infliximab, mycophenolate, methotrexate) who had been stable for 2 years on etanercept. She was diagnosed with biopsy-proven systemic sarcoidosis with meningeal and parenchymal neurosarcoidosis. She was switched to infliximab and methotrexate, with clinical and imaging improvements...

Spermatogenesis is a highly regulated process that takes place in the seminiferous tubules of testis. This process initiates at puberty with differentiation of spermatogonia and their meiotic entry. The initiation of spermatogenesis depends on gonadotropins secreted by the pituitary gland; i.e., follicle-stimulating hormone (FSH) and luteinizing hormone (LH). In the absence of FSH and LH only premeiotic germ cells are present in the testis. The prepubertal development phase in juvenile testis is characterized by a protracted hypogonadotropic state, which only consists of Sertoli and undifferentiated germ cells in the seminiferous epithelium...

The T helper (Th)1/Th2 imbalance plays a crucial role in the development of rheumatoid arthritis (RA). It is well known that basophils can affect the Th1/Th2 balance by enhancing the Th2 response, while impairing the Th1 response, which is known to be involved in the development of a number of diseases. However, limited information is available with regard to the role of basophils in RA. Decreased levels of circulating basophils and a dominant Th1 response have been reported in adult patients with RA, while children with juvenile RA have been largely found to have increased levels of circulating basophils and a dominant Th2 response...

Studying the factors that control gene expression is of substantial importance for rheumatic diseases with poorly understood etiopathogenesis. In the past, gene expression microarrays have been used to measure transcript abundance on a genome-wide scale in a particular cell, tissue or organ. Microarray analysis has led to gene signatures that differentiate rheumatic diseases, and stages of a disease, as well as response to treatments. Nowadays, however, with the advent of next-generation sequencing methods, massive parallel sequencing of RNA tends to be the technology of choice for gene expression profiling, due to several advantages over microarrays, as well as for the detection of non-coding transcripts and alternative splicing events...

RATIONALE, AIMS AND OBJECTIVES: In rheumatic disorders, one of the treatment objectives is to improve the patient's quality of life (QoL). Similar to other chronic conditions, drug compliance is poor, but necessary for successful treatment. The relationship between drug compliance and QoL has never been tested. The aim of this study was to elucidate the relationship between drug compliance and QoL in patients with different rheumatic disorders. METHOD: A cross-sectional study was conducted and patients ≥18 years of age with rheumatoid arthritis (RA), spondyloarthritis (SA), juvenile idiopathic arthritis (JIA) and systemic scleroderma (SSc) were recruited...

Juvenile idiopathic arthritis (JIA) is the most common chronic rheumatic disease of the childhood with the highest risk of disability. Active disease persists in the adulthood in a significant portion of children with juvenile rheumatoid arthritis despite many developments in the diagnosis and treatment. Therefore, initiation of efficient treatment in the early period of the disease may provide faster control of the inflammation and prevention of long-term harms. In recent years, treatment options have also increased in children with juvenile idiopathic arthritis owing to biological medications...
