Examining the association between autism spectrum disorder and atopic eczema: meta-analysis of current evidence. Pediatr Res 2024:10.1038/s41390-024-03456-1. [PMID: 39128926 DOI: 10.1038/s41390-024-03456-1] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/21/2023] [Revised: 07/03/2024] [Accepted: 07/18/2024] [Indexed: 08/13/2024]
Abstract
OBJECTIVES This study aims to investigate the association between autism spectrum disorder (ASD) and atopic eczema (AE), shedding light on potential associations and underlying mechanisms. METHODS A comprehensive review of literature was conducted to identify relevant studies published up to August 2023. Various electronic databases, including PubMed, Embase, Scopus, Web of Science, and Cochrane, were searched using specific keywords related to ASD and AE. RESULTS The meta-analysis covered a total of 30 studies. The first analysis included 23 studies with a combined total of 147430 eczema patients in the ASD group and 8895446 eczema patients in non-ASD group. We calculated the risk ratio of eczema in ASD and non-ASD groups, which revealed a significantly higher risk of eczema in patients with ASD (RR 1.34; 95% CI 1.03, 1.76). The second analysis included seven studies with a combined total of 3570449 ASD patients in the AE group and 3253973 in the non-Eczema group. The risk ratio of ASD in the Eczema and Non-Eczema groups showed a significantly increased risk of ASD in patients with eczema (RR 1.67; 95% CI 0.91, 3.06). CONCLUSION This study underscores the possible link between ASD and atopic eczema, shedding light on their potential association. IMPACT Our study conducted a meta-analysis on the association between autism spectrum disorder (ASD) and atopic eczema (AE), shedding light on potential associations and underlying mechanisms. The review we conducted covered a total of 30 studies. This study underscores the possible link between ASD and atopic eczema, shedding light on their potential association.

Kiran NS, Yashaswini C, Chatterjee A. Zebrafish: A trending model for gut-brain axis investigation. AQUATIC TOXICOLOGY (AMSTERDAM, NETHERLANDS) 2024; 270:106902. [PMID: 38537435 DOI: 10.1016/j.aquatox.2024.106902] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 02/05/2024] [Revised: 03/04/2024] [Accepted: 03/13/2024] [Indexed: 04/13/2024]
Abstract
Zebrafish (Danio rerio) has ascended as a pivotal model organism in the realm of gut-brain axis research, principally owing to its high-throughput experimental capabilities and evolutionary alignment with mammals. The inherent transparency of zebrafish embryos facilitates unprecedented real-time imaging, affording unparalleled insights into the intricate dynamics of bidirectional communication between the gut and the brain. Noteworthy are the structural and functional parallels shared between the zebrafish and mammalian gut-brain axis components, rendering zebrafish an invaluable model for probing the molecular and cellular intricacies inherent in this critical physiological interaction. Recent investigations in zebrafish have systematically explored the impact of gut microbiota on neurodevelopment, behaviour, and disease susceptibility, underscoring the model's prowess in unravelling the multifaceted influence of microbial communities in shaping gut-brain interactions. Leveraging the genetic manipulability inherent in zebrafish, researchers have embarked on targeted explorations of specific pathways and molecular mechanisms, providing nuanced insights into the fundamental functioning of the gut-brain axis. This comprehensive review synthesizes pivotal findings and methodological advancements derived from zebrafish-based gut-brain axis research, accentuating the model's potential to significantly advance our understanding of this complex interplay. Furthermore, it underscores the translational significance of these insights, offering promising avenues for the identification of therapeutic targets in neuro-gastroenterological disorders and psychiatric conditions intricately linked with gut-brain interactions.
