Multisite chronic pain (MCP) involves coordinated neuro-immune-metabolic changes, linking depression and rheumatoid arthritis (RA). These multi-omic signatures predict disease risk and brain changes, highlighting MCP as a systems-level phenotype.
Area of Science:
- Neuroscience
- Immunology
- Metabolomics
- Psychiatry
Background:
- Multisite chronic pain (MCP) often co-occurs with immune and depressive disorders.
- The underlying biological mechanisms and cross-domain dysregulation in MCP remain unclear.
Purpose of the Study:
- To investigate multi-omic signatures associated with MCP.
- To explore the relationship between MCP, immune disorders (rheumatoid arthritis - RA), and depression.
- To identify shared molecular mechanisms linking these conditions.
Main Methods:
- Utilized UK Biobank data from 19,484 participants with up to 15.9-year follow-up.
- Analyzed multi-omic data including biochemical measures, metabolites, and proteins.
- Employed Mendelian randomization to identify causal risk and protective factors.
Main Results:
- Identified MCP-related multi-omic signatures (biochemicals, metabolites, proteins) showing graded dysregulation with increasing disease burden (controls < depression < RA < comorbidity).
- These signatures were associated with increased risk for incident RA and depression, partially mediating their bidirectional association.
- Discovered specific genes (HNMT, FGF21, MME) and factors (platelet count) linked to RA and depression, with some acting as shared factors.
Conclusions:
- MCP reflects coordinated neuro-immune-metabolic dysregulation underlying RA-depression comorbidity.
- MCP acts as a systems-level phenotype connecting immune processes and depression.
- Identified multi-omic signatures associated with brain structural changes and health behaviors.
