MEVALONATE KINASE DEFICIENCY. Mevalonate kinase deficiency is a rare, autosomal recessive, auto- inflammatory disease, linked to mutations in the gene MVK, resulting in the activation of pyrin inflammasome and hypersecretion of interleukin-1β (IL-1β). The clinical spectrum realizes a continuum which extends from the mild phenotype of the partial MVK deficiency (hyperimmunoglobulinemia D) resulting in periodic fever syndrome to a letal form of mevalonate aciduria (MA, complete MVK deficiency).

As in adult patients, sight-threatening ocular manifestations may lead to diagnosis. In this study, we aimed to report a series of cases of PBD with ocular manifestations and provide a review of the literature.

This study aimed to further define the frequency, characteristics and treatment of EO events in CRMO and whether different phenotypes can be distinguished and benefit from special management.
Methods: This multicentre retrospective study included CRMO patients followed in several paediatric rheumatology departments in France between 2015 and 2022.
