Autoinflammatory diseases (AIDs) are a distinct group of diseases characterised by a dysregulation of the innate immune response leading to systemic inflammation. The clinical spectrum of these conditions is extremely variable and possibly every system and tissue can be involved, including the central nervous system (CNS). Indeed, neurological...

Type I interferonopathies are a clinically heterogeneous group of inherited disorders of the innate immune system characterized by constitutive activation of the type I interferon signaling pathway. Cutaneous vasculopathy, lipodystrophy, interstitial lung disease and brain calcifications are the typical manifestations characterizing affected...

A growing number of monogenic immune-mediated diseases have been related to genes involved in pathways of actin cytoskeleton remodeling. Increasing evidences associate cytoskeleton defects to autoinflammatory diseases and primary immunodeficiencies. We reviewed the pathways of actin cytoskeleton remodeling in order to identify inflammatory and...

(1) Background: Familial Mediterranean Fever (FMF) is the prototypal autoinflammatory disease, characterized by recurrent bursts of neutrophilic inflammation. (2) Methods: In this study we look at the most recent literature on this condition and integrate it with novel information on treatment resistance and compliance. (3) Results: The...

Aims Accumulating evidence suggests idiopathic recurrent pericarditis as a disease of probable autoinflammatory origin, and thus anakinra could be of benefit. The goal of this systematic review was to assess the efficacy and safety of anakinra in this context. Methods Reports relevant to anakinra administration in patients with idiopathic...

In the originally published version of this manuscript, there was an error in the title. The title referred to: "Haploidentical a/b T-cell and B-cell stem cell transplantation in severe mevalonate kinase deficiency". This has now been corrected to: "Haploidentical a/b T-cell and B-cell depleted stem cell transplantation in severe mevalonate...

Objective: Mevalonic aciduria represents the most severe form of mevalonate kinase deficiency (MKD). Patients with mevalonic aciduria have an incomplete response even to high doses of anti-cytokine drugs such as anakinra or canakinumab and stem cell transplantation (SCT) represents a possible therapy for this severe disease. Methods: We report...

Background: Hyperferritinemic syndromes are systemic inflammatory disorders characterized by a dysfunctional immune response, which leads to excessive activation of the monocyte-macrophage system with hypercytokinemia and may pursue a rapidly fatal course. Case presentation: We describe two patients of 11 and 9 years of age with...

Syndrome of undifferentiated recurrent fever (SURF) is a heterogeneous group of auto-inflammatory diseases (AID) characterized by self-limiting episodes of systemic inflammation without a confirmed molecular diagnosis, not fulfilling the criteria for periodic fever, aphthous stomatitis, pharyngitis and adenopathy (PFAPA) syndrome. In this...

Neutrophil extracellular traps (NETs) are macromolecular structures programmed to trap circulating bacteria and viruses. The accumulation of NETs in the circulation correlates with the formation of anti-double-stranded (ds) DNA antibodies and is considered a causative factor for systemic lupus erythematosus (SLE). The digestion of DNA by DNase1...

Multisystem inflammatory syndrome in children (MIS-C) is a potentially life-threatening disease temporally linked to SARS-CoV-2 whose incidence and clinical presentation may have been altered by the different SARS-CoV-2 variants and by vaccination.Methods We retrospectively collected the data of all MIS-C cases admitted to the Gaslini...

Objectives. Recent laboratory and clinical data suggest that two prototype autoimmune diseases, systemic lupus erythematosus and rheumatoid arthritis are mainly driven by distinct cytokines, interferon (IFN)-α and tumour necrosis factor (TNF)-α, respectively. We here investigated the presence and characteristics of natural type I IFN-producing...

Gain-of-function mutations in NLRP3 are linked to cryopyrin-associated periodic syndromes (CAPS). Although NLRP3 autoinflammasome assembly triggers inflammatory cytokine release, its activation mechanisms are not fully understood. Our study used a functional genetic approach to identify regulators of NLRP3 inflammasome formation. We identified...

Juvenile systemic lupus erythematosus (jSLE) is a complex inflammatory autoimmune disorder. In the last decades, genetic factors and activation pathways have been increasingly studied to understand their potential pathogenetic role better. Genetic and transcriptional abnormalities directly involved in the type I interferon (IFN) signaling...

OBJECTIVES: Henoch-Schönlein purpura (HScP) may present in children with severe, occasionally refractory, gastrointestinal (GI) involvement. The use of corticosteroids (CSs) is commonplace in the management of the disease, but to date no standardized protocol is available and, although rare, resistance to CS therapy may be challenging to...

Heterozygous mutations of the ACAN gene have been associated with a broad spectrum of non-lethal skeletal dysplasias, called Aggrecanopathies. We report a case of a child with severe inflammatory elbow involvement mimicking septic arthritis who carried the new ACAN missense variant c.6970 T > C, p.Trp2324Arg. The comprehensive clinical...
