Top 100 Most Cited Articles on Hidradenitis Suppurativa

Background: Hidradenitis Suppurativa (HS) is a chronic condition that requires prompt diagnosis and treatment. To date, no bibliometric analysis on HS exists. Analyzing the top 100 citations is important to understand the characteristics of the most influential studies in the HS research landscape, and to guide future research. Objective: To analyze the top 100 most cited articles on HS using bibliometric analysis. Methods: Searches within Scopus and Web of Science using "Hidradenitis Suppurativa" and "Acne Inversa" were conducted on May 14th, 2020. After excluding non-original articles, data for the top 100 articles were analyzed using R-studio and Bibliometrix. Five independent reviewers identified study topic and design. Results: The top 100 most cited articles on HS were published between 1982 and 2017 with an average of 128.3 citations. The top research topic and design were treatment (40 articles) and randomized controlled trials (9), respectively. 2011 had the highest number of publications (9), and the 2012 article by Gregor B. E. Jemec had the highest citations (439). These articles were from 14 different countries with the United States and Denmark as top countries. 27 journals published these articles with the British Journal of Dermatology (BJD) as the top journal. Denmark had the greatest outside country collaborations. Conclusions: The results of our study showed that HS research is steadily growing with greatest support from the BJD. There is a focus on treatments in HS research with the United States and European countries leading the way. However, greater worldwide research of HS is needed.
