Juvenile idiopathic arthritis is the most common chronic rheumatic disease of unknown aetiology in childhood and predominantly presents with peripheral arthritis. The disease is divided into several subgroups, according to demographic characteristics, clinical features, treatment modalities and disease prognosis. Systemic juvenile idiopathic arthritis, which is one of the most frequent disease subtypes, is characterized by recurrent fever and rash. Oligoarticular juvenile idiopathic arthritis, common among young female patients, is usually accompanied by anti-nuclear antibodie positivity and anterior uveitis...

Familial Mediterranean fever (FMF) is the most common hereditary auto-inflammatory (periodic fever) syndrome, and usually successfully treated with colchicine. However, nearly 5-10% of FMF cases are resistant or intolerant to colchicine and treatment options are highly restricted in these cases. Biologics including anakinra, canakinumab, rilonacept, etanercept, infliximab, interferon-alpha, and tocilizumab are shown to have efficacy to control FMF attacks. Tofacitinib, a Janus kinase (JAK) inhibitor, is an orally administered non-biologic disease modifying anti-rheumatic drug for the treatment of rheumatoid arthritis (RA)...

Familial Mediterranean fever (FMF) is the most frequent of all hereditary autoinflammatory syndromes. It is characterized by recurrent attacks of fever and serositis. If not treated it may be complicated with AA amyloidosis. It is caused by mutations in the MEFV gene that encodes pyrin which is involved in the regulation of IL-1β. The mainstay of treatment is colchicine, however a subset of patients requires an alternative treatment either due to inadequate response or intolerance. The accumulating data indicates that anti IL-1 drugs are effective in treating colchicine resistant FMF cases and improving their quality of life...

The IL-1β gene is currently topic of interest for its important role in the pathogenesis of intervertebral disc degeneration. The new sequencing technology makes it crucial to study the effects of variants in IL-1β. Thus, 714 IL-1β variants with evidence supporting were collected from the EMBL database. Among them, 62 were nonsynonymous single nucleotide variants (nsSNVs). Furthermore, six common nsSNVs were predicted to have damaging effects by SIFT, PolyPhen, PROVEAN and SNPs&GO. Based on the constructed three-dimensional structure of pro-IL-1β, rs375479974 with a mutation of Phe to Ser was proposed to reduce the stability of the pro-IL-1β protein...

BACKGROUND: Inflammatory bowel disease can develop in the context of some rheumatic diseases in childhood, including juvenile idiopathic arthritis (JIA). Inflammatory bowel disease (IBD) is frequently associated with other immune-mediated diseases; however, systemic onset JIA (sJIA) has not previously been connected to IBD. Treatment of sJIA has significantly changed in recent years, possibly causing changes in inflammatory patterns. Therefore, data from the German Center for Pediatric and Adolescent Rheumtology from 2010 until 2015 were analyzed by retrospective chart review...

There is an unmet clinical need for immunotherapeutic strategies that specifically target the active immune cells participating in the process of rejection after solid organ transplantation. The monocyte-macrophage cell lineage is increasingly recognized as a major player in acute and chronic allograft immunopathology. The dominant presence of cells of this lineage in rejecting allograft tissue is associated with worse graft function and survival. Monocytes and macrophages contribute to alloimmunity via diverse pathways: antigen processing and presentation, costimulation, pro-inflammatory cytokine production, and tissue repair...

Atopic dermatitis (AD) is a common skin inflammatory disease characterized by the production of thymic stromal lymphopoietin (TSLP) and a marked TH 2 polarization. Recent studies suggest that IL-1β contributes to the development of AD skin inflammation. Here, we have investigated the impact of IL-1β signalling on the epidermal homeostasis of both healthy subjects and AD patient [with functional filaggrin (FLG) alleles] with particular attention to TSLP production and keratinocyte differentiation. In healthy reconstructed human epidermis (RHE), IL-1β promoted: (i) a robust secretion of TSLP in an NFkB-dependant manner and (ii) a significant decrease in the expression of filaggrin and other proteins of the epidermal differentiation complex...

Pyoderma gangrenosum (PG) is an orphan disease. While research on such disorders is based on only few randomized multicenter as well as retrospective studies, most of the data comes from case series of small patient groups. Apart from topical and intralesional therapeutic options for early stages and mild disease courses, treatment predominantly involves systemic therapeutic agents. Besides systemic corticosteroids and cyclosporine A (CsA), options also include intravenous immunoglobulins (IVIG) and biologics such as the TNFα inhibitors infliximab, adalimumab, and etanercept; the interleukin (IL) 12/23 antibody ustekinumab; the IL-1 receptor antagonist anakinra; and the IL-1β antibody canakinumab...

Das Pyoderma gangraenosum (PG) gehört zu den orphan diseases, deren Erforschung sich lediglich auf einzelne, randomisierte, multizentrische sowie retrospektive Studien stützen kann und überwiegend auf Fallserien an kleinen Patientenkollektiven beruht. Die Therapie basiert neben topischen und lokal intraläsionalen Therapieoptionen, bei initialem und leichtem Krankheitsverlauf, insbesondere auf der Gabe von Systemtherapeutika. Diese beinhaltet neben den systemischen Glukokortikosteroiden und Ciclosporin A (CsA) auch Biologika wie intravenöses Immunglobulin G (IVIG), die TNFα-Inhibitoren Infliximab, Adalimumab und Etanercept, den IL-12/23-Antikörper Ustekinumab, den Interleukin-1-Rezeptorantagonist Anakinra und den Interleukin-1β-Antikörper Canakinumab...

BACKGROUND: Canakinumab is a human anti-interleukin-1β (IL-1β) monoclonal antibody neutralizing IL-1β-mediated pathways. We sought to characterize the molecular response to canakinumab and evaluate potential markers of response using samples from two pivotal trials in systemic juvenile idiopathic arthritis (SJIA). METHODS: Gene expression was measured in patients with febrile SJIA and in matched healthy controls by Affymetrix DNA microarrays. Transcriptional response was assessed by gene expression changes from baseline to day 3 using adapted JIA American College of Rheumatology (aACR) response criteria (50 aACR JIA)...

The introduction of omalizumab to the management of chronic spontaneous urticaria (CSU) has markedly improved the therapeutic possibilities for both, patients and physicians dealing with this disabling disease. But there is still a hard core of patients who do not tolerate or benefit from existing therapies and who require effective treatment. Novel approaches include the use of currently available drugs off-licence, investigational drugs currently undergoing clinical trials and exploring the potential for therapies directed at pathophysiological targets in CSU...

Systemic juvenile idiopathic arthritis (sJIA) is the form of childhood arthritis whose treatment is most challenging. The demonstration of the prominent involvement of interleukin (IL)-1 in disease pathogenesis has provided the rationale for the treatment with biologic medications that antagonize this cytokine. The three IL-1 blockers that have been tested so far (anakinra, canakinumab, and rilonacept) have all been proven effective and safe, although only canakinumab is currently approved for use in sJIA. The studies on IL-1 inhibition in sJIA published in the past few years suggest that children with fewer affected joints, higher neutrophil count, younger age at disease onset, shorter disease duration, or, possibly, higher ferritin level may respond better to anti-IL-1 treatment...

Ahmet Gül
Familial Mediterranean fever (FMF) is the most common form of monogenic autoinflammatory conditions, and response to colchicine has been considered as one of its distinctive features among other hereditary periodic fever disorders. Prophylactic colchicine has been shown to be effective in the prevention of inflammatory attacks and development of amyloidosis. However, the highest tolerable doses of colchicine may not be adequate enough to manage these goals in approximately 5% of FMF patients. Inadequate response to colchicine in fully compliant FMF patients may be associated with genetic and/or environmental factors affecting disease severity and colchicine bioavailability...
