Deciphering the Causality between Gut Microbiota Dysbiosis and Poisoning by Narcotics and Psychodysleptics: A
1Department of Anesthesiology, China-Japan Union Hospital of Jilin University, Changchun, China.
Background:
This study investigates the connection between gut microbiota and poisoning caused by narcotics and psychodysleptics, using Mendelian randomization (MR) to explore possible causal relationships.
Methods:
The study employed the MR analysis, leveraging genetic variants as instrumental variables to facilitate robust causal inference. Data for gut microbiota was extracted from the MiBioGen study, integrating genome-wide genotyping data with 16S fecal microbiota profiles. Outcome metrics were based on the Finngen study. Genetic instruments were meticulously extracted based on stringent criteria, and harmonized with SNP outcomes associated with "Poisoning by narcotics and psychodysleptics (hallucinogens)". The inverse-variance weighted (IVW) method was utilized for MR analysis, supplemented by sensitivity analyses including MR-Egger Regression, Weighted Median Approach, and Leave-One-Out Cross-Validation.
Results:
Among various microbial groups, nine showed significant statistical links. Specifically, Class Negativicutes (OR 5.68, 95% CI 2.13-15.16, p = 0.0005) and Order Selenomonadales (OR 5.68, 95% CI 2.13-15.16, p = 0.0005) were notably associated. These findings were consistent across different sensitivity analyses.
Conclusion:
The relationship between gut microbiota and the adverse effects of narcotics and psychodysleptics is an emerging area of research. Our MR study identifies certain microbes that might influence the body's response to these substances. These insights could help in predicting and treating the effects of narcotics and psychodysleptics in the future.
Insights
This study used Mendelian randomization to link specific gut microbes, like Negativicutes and Selenomonadales, to poisoning from narcotics and psychodysleptics, suggesting potential future treatments.
Area of Science:
- Microbiome research
- Pharmacogenomics
- Toxicology
Background:
- Emerging evidence suggests a link between gut microbiota composition and responses to various substances.
- Understanding these connections is crucial for managing adverse effects of drugs.
Purpose of the Study:
- To investigate the potential causal relationship between gut microbiota and poisoning from narcotics and psychodysleptics (hallucinogens).
- To identify specific microbial taxa associated with increased risk or altered response to these substances.
Main Methods:
- Mendelian randomization (MR) analysis utilizing genetic variants as instrumental variables.
- Microbiota data from the MiBioGen study and outcome data from the Finngen study.
- Inverse-variance weighted (IVW) method with sensitivity analyses (MR-Egger, Weighted Median, Leave-One-Out).
Main Results:
- Nine microbial groups showed statistically significant associations with poisoning by narcotics and psychodysleptics.
- Class Negativicutes and Order Selenomonadales were notably linked (OR 5.68, p = 0.0005).
- Findings were robust across sensitivity analyses.
Conclusions:
- The study provides evidence for a potential causal role of specific gut microbes in the body's response to narcotics and psychodysleptics.
- These findings open avenues for novel therapeutic strategies targeting the gut microbiome.
