Medications significantly alter the gut microbiome and host features more than cardiometabolic disease itself. Combined drug therapies can improve metabolome and microbiome health, offering new insights into drug-host-microbiome interactions.
Area of Science:
- Microbiome research
- Pharmacogenomics
- Metabolomics
Background:
- Cardiometabolic disease progression is linked to altered gut microbiome and metabolome.
- Heavy medication use in patients complicates biomarker discovery.
- Understanding drug effects on host-microbiome interactions is crucial.
Purpose of the Study:
- To disentangle the effects of drugs versus disease on host and gut microbiome features.
- To quantify the impact of single medications, combinations, and additive effects.
- To identify drug-host-microbiome signatures in cardiometabolic disease.
Main Methods:
- Integrated multi-omics analyses of 2,173 European residents (MetaCardis cohort).
- Computational framework to infer drug effects on host and microbiome variability.
- Quantification of medication effects, including combinations and additive impacts.
Main Results:
- Drug effects on host and microbiome variability exceed those of disease.
- Additive drug effects shift metabolome and microbiome towards a healthier state.
- Antibiotic use correlates with microbiome changes associated with cardiometabolic disease severity.
- Drug dosage shows a relationship with clinical marker improvement and microbiome composition.
Conclusions:
- A computational framework is presented to disentangle drug and disease effects in multimedicated individuals.
- Identified signatures offer new hypotheses for drug-host-microbiome interactions in cardiometabolic disease.
- Medications play a significant role in shaping the host-microbiome axis during disease progression.
