Altered oral microbiome composition in mental disorders: a systematic review and meta-analysis.
Introduction: Emerging research underscores the gut-brain axis in mental disorder pathophysiology, yet the oral microbiome's contribution to mental health remains underexplored. Elucidating oral microbial signatures in mental and neurological disorders may reveal novel pathobiological mechanisms and advance biomarker discovery for precision diagnostics and microbiota-targeted interventions.
Methods: This systematic review and meta-analysis investigates oral microbiota alterations across 6 different mental disorders, by synthesizing data from 20 case-control studies retrieved from PubMed, Embase, and Cochrane Library. Relative microbial abundance and beta diversity indices were extracted from between-group comparisons. Random-effects meta-analyses were conducted for alpha diversity to characterize microbiota differences between patients and controls.
Results: Key findings included a significantly higher Simpson Index in patients (SMD = 0.42; 95% CI, 0.25 to 0.60) compared to controls. Beta diversity varied significantly only in SZ and MDD. Condition-specific variations in microbial abundance were observed: Rothia enrichment in ASD, overrepresentation of H2S-producing genera in SZ, and reduced Solobacterium and Leptotrichia in MDD.
Conclusion: Collectively, the meta-analytical synthesis suggests alterations in oral microbiota diversity across mental disorders. Disease-associated microbial shifts highlight the oral microbiome as a candidate factor warranting further investigation for potential diagnostic applications and microbial-targeted therapeutic strategies.
期刊介绍:
As the first Open Access journal in its field, the Journal of Oral Microbiology aims to be an influential source of knowledge on the aetiological agents behind oral infectious diseases. The journal is an international forum for original research on all aspects of ''oral health''. Articles which seek to understand ''oral health'' through exploration of the pathogenesis, virulence, host-parasite interactions, and immunology of oral infections are of particular interest. However, the journal also welcomes work that addresses the global agenda of oral infectious diseases and articles that present new strategies for treatment and prevention or improvements to existing strategies.
Topics: ''oral health'', microbiome, genomics, host-pathogen interactions, oral infections, aetiologic agents, pathogenesis, molecular microbiology systemic diseases, ecology/environmental microbiology, treatment, diagnostics, epidemiology, basic oral microbiology, and taxonomy/systematics.
Article types: original articles, notes, review articles, mini-reviews and commentaries
