Insights
Research on childhood allergic diseases like eczema is rapidly expanding, while cough-variant asthma receives significantly less attention. This disparity highlights knowledge gaps and informs future research priorities in pediatric allergy.
Area of Science:
- Pediatric Allergy and Immunology
- Bibliometrics
- Public Health
Background:
- Childhood allergic diseases, including eczema, allergic rhinitis, and asthma, represent a growing global health concern.
- Existing research is fragmented, necessitating a comprehensive overview to guide future investigations.
Purpose of the Study:
- To conduct a bibliometric analysis of research on childhood allergic diseases from 2014 to 2024.
- To identify publication trends, key researchers, evolving research themes, and collaboration patterns.
Main Methods:
- Bibliometric analysis utilizing data from Web of Science, Scopus, and PubMed (2014-2024).
- Inclusion of English-language articles and reviews.
- Analysis of publication patterns, geographic distribution, author contributions, citation networks, and keyword co-occurrence using VOSviewer and CiteSpace.
Main Results:
- Eczema research shows substantial growth, while cough-variant asthma has limited published studies (110 papers in 10 years).
- The United States and China are leading contributors, with significant research output.
- Research focus has shifted towards the microbiome, genetics, novel treatments, environmental factors, comorbidities, and COVID-19 impacts.
- Collaboration patterns vary, indicating uneven research development across different allergic diseases.
Conclusions:
- Significant disparities exist in research volume for childhood allergic diseases, with eczema being heavily studied and cough-variant asthma under-researched.
- This bibliometric overview provides critical insights for strategic research planning and improving clinical management in pediatric allergy.
Introduction:
Childhood allergic diseases, such as eczema, allergic rhinitis, bronchial asthma, and cough-variant asthma, are a growing health concern around the world. There is a lot of research about these diseases, but a clear and complete study is still needed to better understand them and help guide future research.
Methods:
This study used a bibliometric analysis of research on childhood allergic diseases from 2014 to 2024. The main goal was to find patterns in publications, main researchers, research focuses, teamwork between groups, and new topics. Data were collected from Web of Science, Scopus, and PubMed. The study included English-language articles and reviews only. The tools VOSviewer and CiteSpace were used to study publication patterns, where research was done, which authors and journals worked together, how often papers were cited together, which papers were cited the most, and how keywords appeared and formed groups.
Results:
The amount of research was different for each disease. Eczema got the most attention and kept growing. Cough-variant asthma had fewer studies. The United States and China were the main countries that did most of the work and had well-known authors. The focus of studies changed from general studies about disease spread to more detailed topics like the microbiome, genetics, special treatments, environmental causes, other health problems that happen together, and the effects of COVID-19. The way researchers worked together was not the same for all diseases. This showed that research was more developed and better connected for some diseases and less developed for others, mainly for cough-variant asthma.
Conclusion:
This study gives a short look at recent research on childhood allergic diseases. It shows that eczema research is growing fast, but cough-variant asthma is still studied much less, with only 110 papers in 10 years. This big difference shows a clear lack of knowledge. These results can help make better research plans and improve medical care in this field.

Inflammatory bowel disease, commonly known as IBD, refers to a collection of disorders that lead to persistent inflammation of the gastrointestinal tract. The two types of IBD are ulcerative colitis, which impacts the colon, and Crohn's disease, which can involve any part of the gastrointestinal segment.
