A few weeks after the peak of the global 2019 novel coronavirus disease pandemic, cases of shock, multisystem inflammation and severe myocarditis have occurred in children and adolescents, generating some concerns and above all many questions. An almost immediate association raised with shock syndrome related to Kawasaki disease (KD). However, in light of bo/th experience and literature have taught us about severe acute respiratory syndrome coronavirus 2 (SARS-COV-2) infection, and what already known on the epidemiology of KD, we suggest here the hypothesis of a new 'post-viral' systemic inflammatory disease related to excessive adaptive immune response rather than a form of KD caused by SARS-COV-2.

Methotrexate (MTX) is one of the mainstays of treatment for rheumatoid arthritis (RA) and juvenile idiopathic arthritis (JIA) and it is mainly administered either orally or by subcutaneous (SC) injection, which are not so satisfactory. While orally administered MTX is associated with variable bioavailability and causes gastrointestinal side effects, including nausea and vomiting, SC injection is painful and produces high peak blood levels of MTX. Transdermal delivery presents an attractive alternative administration route. Read More

The coronavirus disease 2019 (COVID-19) pandemic has come with many challenges for healthcare providers and patients alike. In addition to the direct burden it has placed on societies and health systems, it had a significant impact in the care of patients with chronic diseases, as healthcare resources were deployed to fight the crisis, and major travel and social restrictions were adopted. In the field of rheumatology, this has required notable efforts from departments and clinicians to adapt to the novel and assure the follow-up of patients with rheumatic and musculoskeletal diseases.

Interestingly, recent evidence from the juvenile counterpart of AOSD suggested the emergent high fatality rate of lung disease (LD) in these patients. In this work, we aimed to characterise LD in AOSD, to identify associated clinical features and predictive factors, and to describe long-term outcomes of the disease comparing patients with LD and those without.

Type I interferons (IFN-Is) are a very important group of cytokines that are produced by innate immune cells but also act on adaptive immune cells. IFN-Is possess antiviral, antitumor, and anti-proliferative effects, as well are associated with the initiation and maintenance of autoimmune disorders. Studies have shown that aberrantly expressed IFN-Is and/or type I IFN-inducible gene signatures in the serum or tissues of patients with autoimmune disorders are linked to their pathogenesis, clinical manifestations, and disease activity.

Background: Many autoimmune diseases share common pathogenic mechanisms, cytokine pathways and systemic inflammatory cascades; however, large studies quantifying the co-existence of autoimmune diseases in patients with juvenile idiopathic arthritis (JIA) have not been conducted.

Methods: We performed a cross-sectional study using two United States administrative healthcare claims databases (Truven Health MarketScan® Commercial Database and IMS PharMetrics database) to screen for the prevalence of multiple autoimmune diseases in patients with JIA and in a control group with attention deficit hyperactivity disorder (ADHD). Patients with a diagnosis code for JIA or ADHD between January 1, 2006 and September 30, 2017 were separated into two age cohorts (< 18 and ≥ 18 years) and matched (maximum 1:5) based on age, sex, number of medical encounters, and calendar year of diagnosis.

Self-healing juvenile cutaneous mucinosis (SHJCM) is a rare childhood disease with characteristic cutaneous and rheumatic manifestations. Cutaneous manifestations include a combination of nodules affecting peri-articular (especially interphalangeal joints) and head and neck areas; and linearly arranged ivory white papules over an erythematous indurated skin. Despite a benign course, an abrupt onset of symptoms with extensive cutaneous involvement often leads to parental anxiety, overenthusiastic evaluation and sometimes aggressive treatment. Read More
