    Adult-onset Still's disease (AOSD) is a rare inflammatory disease of unknown etiology typically characterized by episodes of spiking fever, evanescent rash, arthralgia, leukocytosis, and hyperferritinemia. The pivotal role of interleukin (IL)-1 and other pro-inflammatory cytokines gives rise to the development of new targeted therapies. Currently, AOSD patients can benefit from efficient and well tolerated biologic agents, such as IL-1, IL-6, and tumour necrosis factor (TNF)-\u3b1 antagonists. Canakinumab, a human monoclonal anti-IL-1\u3b2 antibody, is indicated for the treatment of different autoinflammatory syndromes in adults, adolescents, and children and it has recently been approved for AOSD treatment. In this article, we summarize the structural and biochemical data describing the molecular interactions between Canakinumab and its target antigen. Some special considerations of the pharmacological properties of Canakinumab are included. We also review the safety, efficacy and tolerability of this drug for the treatment of AOSD

    Low back pain (LBP) is a common condition with profound effects on well-being. We aimed to define the prevalence and the characteristics of LBP and to investigate its impact on the quality of life (QoL) of 409 students (265 females and 144 males), all high-school adolescents from the Veneto region. LBP was measured with a structured, self-report questionnaire, while the SF-36 questionnaire was used to measure physical and mental QoL. 253 students (61.3%) reported one or more episodes of LBP, with female predominance. Adolescents with LBP treated with drugs and rehabilitation cares have significantly poor belief in pain resolution (p=0.005), but more belief in a prevention program (p=0.006) than the others. After adjustment for sex, a significant association between the SF-36 dimension of vitality and the presence of LBP in males was observed. All SF-36 domains except mental health were significantly higher in females with LBP. Our study confirmed that LBP is frequent in Italian scholar adolescents and has an impact on QoL. Strategies for reducing the effects of LBP on QoL should be an important purpose for clinicians and health policy makers

    SUMMARY The objective was to study both ex vivo and in vitro secretion of pro-inflammatory cytokines in patients affected by Blau syndrome (BS) and carrying p.E383K mutation in the CARD15/NOD2 gene associated with the disease. For ex vivo studies, peripheral blood mononuclear cells (PBMCs), serum from three patients and healthy controls have been collected. PBMCs have been cultured in the presence or absence of inflammatory enhancers, such as lipopolysaccharide (LPS) and muramyl dipeptide (MDP). The levels of interleukin (IL)-1β, IL-6, IL-8, tumor necrosis factor (TNF)-α and interferon (IFN)-γ were assayed by either immunoassay or array-based system. For in vitro studies, different constructs were created cloning human wild-type and p.E383K-mutated NOD2 cDNA into the expression vector pCMV-Tag2c. HEK293 cell lines were stably transfected, cultured with or without MDP and IL-8 level was assayed in their surnatants. Statistical analysis in both studies was performed using non-parametric tests. Both ex vivo and in vitro studies have not identified a significant increase in secretion of the analyzed proinflammatory cytokines. p.E383K-mutated NOD2 transfected cells express low level of IL-8. The ex vivo basal level results from both serum and PBMCs surnatants present similar levels of IL-1β, IL-6, TNF-α and IFN-γ in patients and controls. The presence of the stimulant agents (LPS and MDP), either individual or paired, does not lead to significant increases in all cytokines concentrations in patients compared to controls. Taken together, the ex vivo and in vitro data suggest that there is not a primary mediation of IL-1β and other pro-inflammatory cytokines in BS patients carrying p.E383K

    The role of architectural design for rheumatic patients' wellbeing: the point of view of Environmental Psychology

    Rheumatic diseases (RD) are among the most frequent disorders in the population and the major causes of chronic pain and disability. The resulting consequences are catastrophic, leading to a significant socio-economic burden, which includes significant reductions in quality of life (QoL) and limitations in regular work and daily activities of patients. In spite of this, rheumatic diseases are often misunderstood or diagnosed late, probably due to their characteristics of silent diseases, sometimes unrecognizable to unaffected or unskilled people. Actually, it is surprising that, despite their consequences on QoL and on individual impact, rheumatic diseases are underestimated by the public opinion, which is probably more attracted by other major diseases causing death. This silent perception can even be seen in some among the most recent psycho-social approaches to population needs in the fields of Health Psychology and Environmental Psychology. The latter, also known as Architectural Psychology, is a branch of Psychology that analyses the effects of the built environment on humans, including those affected by diseases. Paradoxically, in many cases, some components of the environments created to protect individuals and/or the population may represent barriers and subsequently causes of disability and suffering in patients with rheumatic diseases. In order to increase awareness about this particular aspect of social life, HEMOVE Onlus, a non-profit association, has promoted the creation of a multidisciplinary Task Group, which included mainly rheumatologists, psychologists and architects, with the aim of applying also for the benefit of rheumatic patients the most modern technical skills available in the context of Environmental Psychology, including in particular design and information technology

    A Snapshot on the On-Label and Off-Label Use of the Interleukin-1 Inhibitors in Italy among Rheumatologists and Pediatric Rheumatologists: A Nationwide Multi-Center Retrospective Observational Study.

    Background: Interleukin (IL)-1 inhibitors have been suggested as possible therapeutic options in a large number of old and new clinical entities characterized by an IL-1 driven pathogenesis. Objectives: To perform a nationwide snapshot of the on-label and off-label use of anakinra (ANA) and canakinumab (CAN) for different conditions both in children and adults. Methods: We retrospectively collected demographic, clinical, and therapeutic data from both adult and pediatric patients treated with IL-1 inhibitors from January 2008 to July 2016. Results: Five hundred and twenty-six treatment courses given to 475 patients (195 males, 280 females; 111 children and 364 adults) were evaluated. ANA was administered in 421 (80.04%) courses, CAN in 105 (19.96%). Sixty-two (32.1%) patients had been treated with both agents. IL-1 inhibitors were employed in 38 different indications (37 with ANA, 16 with CAN). Off-label use was more frequent for ANA than CAN (p < 0.0001). ANA was employed as first-line biologic approach in 323 (76.7%) cases, while CAN in 37 cases (35.2%). IL-1 inhibitors were associated with corticosteroids in 285 (54.18%) courses and disease modifying anti-rheumatic drugs (DMARDs) in 156 (29.65%). ANA dosage ranged from 30 to 200 mg/day (or 1.0-2.0 mg/kg/day) among adults and 2-4 mg/kg/day among children; regarding CAN, the most frequently used posologies were 150mg every 8 weeks, 150mg every 4 weeks and 150mg every 6 weeks. The frequency of failure was higher among patients treated with ANA at a dosage of 100 mg/day than those treated with 2 mg/kg/day (p = 0.03). Seventy-six patients (14.4%) reported an adverse event (AE) and 10 (1.9%) a severe AE. AEs occurred more frequently after the age of 65 compared to both children and patients aged between 16 and 65 (p = 0.003 and p = 0.03, respectively). Conclusions: IL-1 inhibitors are mostly used off-label, especially ANA, during adulthood. The high frequency of good clinical responses suggests that IL-1 inhibitors are used with awareness of pathogenetic mechanisms; adult healthcare physicians generally employ standard dosages, while pediatricians are more prone in using a weight-based posology. Dose adjustments and switching between different agents showed to be effective treatment strategies. Our data confirm the good safety profile of IL-1 inhibitors

    Adult-onset Still’s disease (AOSD) is a rare multifactorial autoinflammatory disorder of unknown etiology, characterized by an excessive release of cytokines triggered by dysregulated inflammation and articular and systemic manifestations. The clinical spectrum of AOSD ranges from self-limiting forms with mild symptoms to life-threatening cases and presents clinical and biological similarities with the juvenile form (sJIA). Nowadays, the advances in biologic agents no longer limit the treatment to NSAIDs, glucocorticoids, or conventional synthetic DMARDs. The blockade of IL-1 and IL-6 is effective in the treatment of systemic and articular inflammation of AOSD patients; however, novel compounds with different properties and targets are now available and others are being studied. In this review, starting from the pathogenesis of AOSD, we summarized the current and emerging biological therapies, possible effective agents for achieving AOSD control and remission
