Macromolecular immunosuppressive monoclonal antibodies and fusion proteins directed against molecules or cells involved in inflammation and immunity represent a recent and important addition to our therapeutic armamentarium. Tumor necrosis alpha (TNFα) is a cytokine involved in systemic inflammation and clinical utilization of its antagonists has revolutionized treatment of juvenile rheumatoid and psoriatic arthritis, ankylosing spondylitis, Crohn's disease, ulcerative colitis, and plaque psoriasis. Clinical utility has also been demonstrated for use against steroid-refractory graft-vs-host disease and other immune-mediated conditions...

OBJECTIVE: High mobility group box protein 1 (HMGB1) is an important pro-inflammatory mediator in adult rheumatoid arthritis. The diagnostic utility of HMGB1 in Juvenile Idiopathic Arthritis (JIA) is still unclear. The aim was to examine whether serum HMGB1 levels are associated with inflammation, radiological disease progression, and long-term prognosis in JIA. METHODS: We included 131 children with JIA from a population-based prevalence study; 38 of them were prospectively followed up for 10 years...

Alarmins are endogenous molecules with homeostatic roles that have reached the focus of research in inflammatory arthritis in the last two decades, mostly due to their ability to indicate tissue related damage after active or passive release from injured cells. From HMGB1, S100A8/A9 and S100A12 proteins, over heat-shock proteins (HSPs) and purine metabolites (e.g. uric acid, ATP) to altered matrix proteins and interleukin-33 (IL-33), a number of alarmins have been determined until now as having a role in rheumatoid arthritis, psoriatic and juvenile idiopathic arthritis, as well as spondyloarthritis and gout...

Juvenile idiopathic arthritis (JIA) is the most common rheumatic disease in childhood. The pathogenesis of JIA is thought to be the result of a combination of host genetic and environmental triggers. However, the precise factors that determine one's susceptibility to JIA remain to be unravelled. The microbiome has received increasing attention as a potential contributing factor to the development of a wide array of immune-mediated diseases, including inflammatory bowel disease, type 1 diabetes and rheumatoid arthritis...

The annual economic burden of visual disorders in the United States was estimated at $139 billion. Ophthalmology is therefore one of the salient application fields of postgenomics biotechnologies such as proteomics in the pursuit of global precision medicine. Interestingly, the protein composition of the human iris tissue still remains largely unexplored. In this context, the uveal tract constitutes the vascular middle coat of the eye and is formed by the choroid, ciliary body, and iris. The iris forms the anterior most part of the uvea...

Systemic sclerosis (SSc) is a multisystem disease characterized by extensive collagen deposition in skin and internal organs, fibrointimal microvasculopathy, and activation of the immune system. T cells and B cells can promote fibrosis in SSc. Interleukin (IL)-6 is implicated in the pathogenesis of SSc. IL-6 is increased in the peripheral blood and lesional skin from patients with SSc, and induces fibroblast collagen production directly and indirectly by inducing profibrotic M2 macrophages. IL-6 also induces Th17 differentiation and promotes B cell differentiation toward Ig-producing plasma cells...

Total hip arthroplasty in the juvenile patient with a severely diseasedjoint can provide long-term pain relief and improvement in function. We present a patient with juvenile rheumatoid arthritis who underwent a Mittelmeier ceramic-on-ceramic total hip arthroplasty at age 12 in 1986. The implant provided the patient with a functioning hip for 24 years, but subsequently required revision due to femoral component loosening. This case report represents the longest reported clinical follow-up of noncemented, ceramic-on-ceramic total hip arthroplasty in a juvenile patient and depicts an excellent outcome at 27 years...

The translation of basic insight in immunological mechanisms underlying inflammation into clinical practice of inflammatory diseases is still challenging. Here we describe how-through continuous dialogue between bench and bedside-immunological knowledge translates into tangible clinical use in a complex inflammatory disease, juvenile idiopathic arthritis (JIA). Systemic JIA (sJIA) is an autoinflammatory disease, leading to the very successful use of IL-1 antagonists. Further immunological studies identified new immune markers for diagnosis, prediction of complications, response to and successful withdrawal of therapy...

The representatives of immunoinflammatory diseases are rheumatic ones, such as primarily rheumatoid arthritis, juvenile idiopathic arthritis, spondyloarthritis, psoriatic arthritis, systemic lupus erythematosus, and other systemic connective diseases, which are characterized by a high risk for untimely death. The high risk of untimely death in these diseases has been found to be associated with the severity of an immunoinflammatory process that gives rise to severe irreversible damage to vital organs and systems and with the development of a wide spectrum of comorbidities (infections, interstitial lung disease, malignant tumors, osteoporotic fractures, etc...

Etanercept is a competitive inhibitor of tumor necrosis factor-alpha (TNF-α) a polypeptide hormone, involved in the development of the immune system, in host defense and immune surveillance. Even if the etanercept mechanism of action is not completely understood, it is supposed that it negatively modulates biological responses mediated by molecules (cytokines, adhesion molecules, or proteinases) induced or regulated by TNF. For this reason, it is widely used in the treatment of immunologicals diseases, such as rheumatoid and psoriatic arthritis, polyarticular juvenile idiopathic active, ankylosing spondylitis, and plaque psoriasis...
