Abstract:
Auto-inflammatory diseases (AIDs) are diseases resulting from an inappropriate activation of innate immunity in the absence of any infection. The field of monogenic AIDs is constantly expanding, with the discovery of new pathologies and pathophysiological mechanisms thanks to pangenomic sequencing. Actinopathies withauto-inflammatorymanifestations are anew emerging group ofAIDs, linked to defects in the regulation of the actin cytoskeleton dynamics. These diseases most often begin in the neonatal period and combine to varying degrees a more or less severe primary immune deficiency, cytopenias (especially thrombocytopenia), auto-inflammatory manifestations (especially cutaneous and digestive), atopic and auto-immune manifestations. The diagnosis is to be evoked essentially in front of a cutaneousdigestive auto-inflammation picture of early onset, associated with a primary immune deficiency and thrombocytopenia or a tendency to bleed. Some of these diseases have specificities, including a risk of macrophagic activation syndrome or a tendency to atopy or lymphoproliferation. We propose here a review of the literature on these new diseases, with a proposal for a practical approach according to the main associated biological abnormalities and some clinical particularities. However, the diagnosis remains genetic, and several differential diagnoses must be considered. The pathophysiology of these diseases is not yet fully elucidated, and studies are needed to better clarify the inherent mechanisms that can guide the choice of therapies. In most cases, the severity of the picture indicates allogeneic marrow transplantation.
