Emerging trends and research hotspots in the relationship between mast cells and atopic dermatitis based on the literature from 2001 to 2024: A bibliometric and visualized analysis

Background Atopic dermatitis (AD) is a prevalent chronic inflammatory and highly pruritic skin condition characterized by the infiltration of immune cells, notably eosinophils and mast cells. Mast cells (MCs) critically participate in the complex pathogenesis of AD through multiple pathways and have recently garnered growing attention in research. Despite the abundance of related studies published over the years, a comprehensive bibliometric analysis on this topic remains lacking. Objective Our objective was to perform an up‐to‐date bibliometric analysis of the literature focusing on the relationship between MCs and AD. This analysis would provide valuable insights through a thorough bibliometric review, enabling a clearer understanding of the current research landscape, pinpointing key studies, and detecting emerging trends within this field. Methods We searched the Web of Science Core Collection (WoSCC) database on 15 July 2024. The data retrieval strategy was structured as follows: #1: TS = (“mast cells”) OR TS = (“mast cell”) OR TS = (“mastocyte”); #2: TS = (“atopic dermatitis”) OR TS = (“atopic eczema”) Final data: (#1 AND #2). A total of 2272 items published between 2001 and 2024 were included. Several scientometric visualization tools, including VOSviewer, R‐bibliometrix, CiteSpace and an online analytical platform, were utilized to conduct text mining and to visualize the bibliometric data, facilitating a comprehensive analysis of research trends and patterns. Results Out of the initial 2272 articles retrieved, 2168 were selected for analysis after applying inclusion and exclusion criteria based on publication type. The findings indicate a steady and substantial exponential growth in the annual number of publications focused on the relationship between over the years. The South Korea (547/2168), USA (465/2168) and Japan (436/2168) were the major contributors within this field, collectively constituting more than half of the total publications. To clarify the underlying mechanisms and role of MCs in the pathogenesis of AD and to make MCs prime targets for therapeutic intervention have garnered the most attention in this field. According to references analysis, the research emphasis has shifted to developing MC‐related therapeutics and intervention and regulating the immune system of AD patients through modulating the activity of various immune cells. On the basis of keywords analysis, we outlined the following research frontiers and hotpots in the f
