Systemic autoinflammatory disorders (SAIDs) are inherited defects of innate immunity characterized by recurrent sterile inflammatory attacks involving skin, joints, serosal membranes, gastrointestinal tube, and other tissues, which recur with variable rhythmicity and display reactive amyloidosis as a potential long-term complication. Dysregulated inflammasome activity leading to overproduction of many proinflammatory cytokines, such as interleukin-1 (IL-1), and delayed shutdown of inflammation are considered crucial pathogenic keys in the vast majority of SAIDs. Progress of cellular biology has partially clarified the mechanisms behind monogenic SAIDs, such as familial Mediterranean fever, tumor necrosis factor receptor-associated periodic syndrome, cryopyrin-associated periodic syndrome, mevalonate kinase deficiency, hereditary pyogenic diseases, idiopathic granulomatous diseases and defects of the ubiquitin-proteasome pathway. Whereas, little is clarified for the polygenic SAIDs, such as periodic fever, aphthous stomatitis, pharyngitis, and cervical adenopathy (PFAPA) syndrome. The puzzle of symptomatic febrile attacks recurring over time in children requires evaluating the mixture of clinical data, inflammatory parameters in different disease phases, the therapeutic efficacy of specific drugs such as colchicine, corticosteroids or IL-1 antagonists, and genotype analysis in selected cases. The long-term history of periodic fevers should also need to rule out chronic infections and malignancies. This review is conceived as a practical template for proper classification of children with recurring fevers and includes tips useful for the diagnostic approach to SAIDs, focusing on the specific acute painful symptoms and hematologic manifestations encountered in childhood.

Autoinflammatory diseases represent a relatively new and rapidly evolving group of rare disorders associated with mutations of genes encoding proteins with a key regulatory role in inflammatory response. Gradual discovery of mechanisms that link genetic disorder with its biochemical and immunological consequences leading to continuous or episodic inflammatory stimulation has enabled introduction of directed immunotherapies. Periodic fever syndromes belong to the so far best-known entities: familial Mediterranean fever, mevalonate kinase deficiency, cryopyrinopathies and TNF-receptor associated periodic syndrome. These inherited disorders usually manifest in childhood with variably long febrile episodes accompanied with the spectrum of other skin and organ inflammatory features and elevation of laboratory markers of inflammation. Uncontrolled disease may lead to secondary amyloidosis. Directed anti-inflammatory therapy can prevent evolution of organ damage. In children benign syndrome of periodic fever with aphtae, pharyngitis and cervical adenitis is the most common self-limited disorder without clear genetic disposition. Following other autoinflammatory disease groups are described - pyogenic syndromes, disorders with skin and bone manifestations, granulomatous diseases, monogenic vasculopathies and diseases associated with proteasome disorder. Diagnosis of autoinflammatory diseases is often delayed due to their extreme rarity. Increasing efficacy and availability of molecular-genetic testing and centralization of diagnostics and clinical care in a specialized center for children as well as adults can in the future improve quality of care for patients with these rare conditions.
