Allergic Contact Dermatitis: Patch Testing Sensitization Patterns and Occupational Risk Factors

About this Research Topic

Background

Allergic contact dermatitis (ACD) is a chronic inflammatory skin condition caused by an allergic response to contact with external allergens, which are often present in everyday products or occupational environments. The condition occurs when the immune system becomes sensitized to certain substances, leading to an exaggerated inflammatory response upon future exposure. ACD is commonly diagnosed through patch testing (PT), a procedure that identifies specific allergens by applying small amounts of potential irritants to the skin. Although PT is the gold standard for diagnosing ACD, its accessibility is unevenly distributed, creating disparities in healthcare and leading to underdiagnosis or delayed diagnosis for many patients.

Occupational allergic contact dermatitis (OACD) is a particularly significant subset of ACD, affecting individuals exposed to allergens in their work environments, such as healthcare workers, construction workers, and cosmetologists. In some industries, exposure to allergens is virtually unavoidable, increasing the risk of ACD in these populations. Common occupational allergens include metals, fragrances, preservatives, rubber accelerators, and solvents, which are frequently encountered in industrial settings, cosmetics, and personal care products.

In addition to occupational exposures, socioeconomic factors such as race, ethnicity, and financial limitations play a critical role in access to PT and subsequent management of ACD. Studies have demonstrated that racial and ethnic minorities may face a higher prevalence of ACD due to differences in exposure to certain products or environmental allergens, compounded by reduced access to dermatological care. Furthermore, the affordability of hypoallergenic products and specialized care is another key barrier to appropriate diagnosis and treatment, exacerbating health disparities in ACD management.

The primary goal of this research topic is to provide a comprehensive understanding of sensitization patterns in patients undergoing patch testing, with an emphasis on occupational exposures and healthcare access disparities. By identifying common allergens and exploring the demographic and occupational characteristics of affected individuals, this research aims to advance knowledge on both the diagnosis and prevention of ACD.

We welcome submissions that provide insight into the following themes:

- Patch Testing Sensitization Patterns: Identifying the most common allergens responsible for ACD in different populations, particularly those undergoing patch testing in specialized dermatology clinics.

- Occupational Risk Factors: Investigating the prevalence of ACD in various high-risk occupations, such as healthcare, construction, and cosmetology, and characterizing the specific allergens these workers are exposed to.

- Healthcare Disparities: Exploring how socioeconomic factors, including race, ethnicity, and financial status, influence access to PT, diagnosis, and treatment, contributing to disparities in ACD management.

- Supplemental Patch Testing: Evaluating the relevance and interpretation of patch test reactions, particularly in cases requiring supplemental testing for complex or less common allergens.

- Occupational Health Policies and Protection: Assessing the effectiveness of workplace regulations, protective equipment, and hygiene practices in reducing the incidence of OACD and improving worker health outcomes.

- Affordability of Hypoallergenic Products: Analyzing the accessibility and affordability of hypoallergenic alternatives for individuals diagnosed with ACD, with attention to socioeconomic disparities that limit access to such products.

This research topic aims to stimulate discussion and research on the interplay between sensitization patterns, occupational risk, and healthcare disparities in the management of ACD. By fostering collaboration between dermatologists, occupational health experts, and public health researchers, we hope to contribute to better diagnostic, preventive, and treatment strategies for this common and often debilitating condition.

Frequently asked questions

• What is a Research Topic?

  Frontiers' Research Topics are collaborative hubs built around an emerging theme.Defined, managed, and led by renowned researchers, they bring communities together around a shared area of interest to stimulate collaboration and innovation.

  Unlike section journals, which serve established specialty communities, Research Topics are pioneer hubs, responding to the evolving scientific landscape and catering to new communities.

• Why does Frontiers publish Research Topics? 

  The goal of Frontiers' publishing program is to empower research communities to actively steer the course of scientific publishing. Our program was implemented as a three-part unit with fixed field journals, flexible specialty sections, and dynamically emerging Research Topics, connecting communities of different sizes and maturity.

  Research Topics originate from the scientific community. Many of our Research Topics are suggested by existing editorial board members who have identified critical challenges or areas of interest in their field.

• Why are Research Topics important for journals?

  As an editor, Research Topics will help you build your journal, as well as your community, around emerging, cutting-edge research. As research trailblazers, Research Topics attract high-quality submissions from leading experts all over the world.

  A thriving Research Topic can potentially evolve into a new specialty section if there is sustained interest and a growing community around it.

• How do we ensure the quality of articles within Research Topics?

  Each Research Topic must be approved by the specialty chief editor, and it falls under the editorial oversight of our editorial boards, supported by our in-house research integrity team. The same standards and rigorous peer review processes apply to articles published as part of a Research Topic as for any other article we publish.

  In 2023, 80% of the Research Topics we published were edited or co-edited by our editorial board members, who are already familiar with their journal's scope, ethos, and publishing model. All other topics are guest edited by leaders in their field, each vetted and formally approved by the specialty chief editor.

• What are the benefits of publishing my article in a Research Topic?

  Publishing your article within a Research Topic with other related articles increases its discoverability and visibility, which can lead to more views, downloads, and citations. Research Topics grow dynamically as more published articles are added, causing frequent revisiting, and further visibility.

  As Research Topics are multidisciplinary, they are cross-listed in several fields and section journals – increasing your reach even more and giving you the chance to expand your network and collaborate with researchers in different fields, all focusing on expanding knowledge around the same important topic.

  Our larger Research Topics are also converted into ebooks and receive social media promotion from our digital marketing team.

   
• What types of articles can be published in a Research Topic?

  Frontiers offers multiple article types, but it will depend on the field and section journals in which the Research Topic will be featured. The available article types for a Research Topic will appear in the drop-down menu during the submission process.
