Autoinflammatory diseases (AIDs) are a relatively new family of disorders, defined about 19 years ago. Some of them are hereditary and some are not. The names given to these diseases do not follow any systematic guidelines, and sometimes the same disorder carries several names. The aim of this study is to refine the definition of AIDs and to provide some conventions for their naming. We focused mainly on monogenetic AIDs. Delphi technique, which enables consensus among a group of experts through internet and mail communication and questionnaires, was employed. After achieving 100% consensus among six members of a steering committee, the questionnaire containing AID definitions and the agreed-upon conventions were sent to 26 physicians and researchers working in the field of AIDs in order to gain broader support for the committee’s proposals. The committee proposed the following definition for AIDs: “Autoinflammatory diseases are clinical disorders caused by defect(s) or dysregulation of the innate immune system, characterized by recurrent or continuous inflammation (elevated acute phase reactants-APR) and the lack of a primary pathogenic role for the adaptive immune system (autoreactive T-cells or autoantibody production).” Several rules were defined for guiding the naming of these diseases among which are: abandoning eponyms and preferring the name of the gene over its encoded protein. The new definition for AIDs allows inclusion of clinical disorders mainly associated with defects in the innate immune system. The new conventions propose names with clinical meaning and in some cases even clues for treatment.
