The Evaluation of Changing the Eponym Churg–Strauss Syndrome Due to the 2012 Revised International Chapel Hill Consensus Conference Nomenclature of Vasculitides

Abstract

Background: Eponyms do not describe any pathogenesis of a disease. So, there is no other way than to memorize the disease or anatomical area. Over the years, new nomenclatures have been suggested for some diseases due to a better understanding of the pathogenesis. In this article, the changes in the use of Churg–Strauss syndrome were investigated. Methods: In the study, a computerized search was performed using the PubMed database. Books and documents, clinical trials, editorials, meta-analyses, reviews, and case reports were included in the study. Data were obtained from the title of the database, and the variations or distribution by year for the nomenclature of the most related studies were evaluated. Results: Overall, 68.3% of the articles included CSS, 25.7% included eosinophilic granulomatous polyangiitis (EGPA), and 6.0% included both nomenclatures. When evaluated in terms of the distribution according to years, it was determined that there was a statistically significant increase in use in terms of EGPA. When evaluated among specific section journals, the highest rate was in Rheumatology (29.4%). The highest rate of using CSS was in the Rheumatology (25.1%) journals, followed by Pulmonary/Respiratory (17%), Cardiovascular (12%), and Allergy/Immunology/Biology (9.8%). The use of EGPA combined with CSS decreased in all the specific journals from 2012 to the present. Conclusions: The findings of the study revealed that the number of articles with the eponym of EGPA showed an increased frequency in contrast to a decreasing frequency for those with CSS during recent years. Today, with the elaboration of the disease pathogenesis and the increase in knowledge, the trend has shifted in this direction.
