Mutations in genes that control class switch recombination and somatic hypermutation during the germinal center (GC) response can cause diverse immune dysfunctions. In particular, mutations in CD40LG, CD40, AICDA, or UNG cause hyper-IgM (HIGM) syndrome, a heterogeneous group of primary immunodeficiencies. Follicular helper (Tfh) and follicular...

BackgroundThe treatment of multisystem inflammatory syndrome in children unresponsive to first-line therapies (IVIG and/or steroids) is challenging. The effectiveness of IL-1 receptor antagonist, anakinra, is debated.Patients and methodsWe conducted an anonymous retrospective multicenter study on MIS-C patients treated with anakinra in Italy...

Objective: To analyse, in a cohort of paediatric patients with recurrent pericarditis (RP) undergoing anti-IL-1 treatment: the agent and dosing used as first line treatment, the long-term efficacy of IL1-blockers, the percentage of patients achieving a drug-free remission, the presence of variables associated with drug-free remission.

To evaluate in real-life the effectiveness and safety of canakinumab in Italian patients with systemic juvenile idiopathic arthritis (sJIA).

The Juvenile Arthritis Multidimensional Assessment Report (JAMAR) is a new parent/patient reported outcome measure that enables a thorough assessment of the disease status in children with juvenile idiopathic arthritis (JIA). We report the results of the cross-cultural adaptation and validation of the parent and patient versions of the JAMAR in...

Patients with 22q11.2 deletion syndrome (22q11.2DS) may develop severe thrombocytopenic purpura and hemolytic anemia. There are no reliable predictors for the development of hematologic autoimmunity (HA) in these patients.
