Genetic variants associated with chronic postsurgical pain: evidence from the China Surgery and Anaesthesia Cohort study

Br J AnaesthPublished Genome-wide association study within a prospective cohort

Authors' conclusion

This study enhances our understanding of the genetic predisposition to chronic postsurgical pain.

Study context

Population
Surgical patients in the China Surgery and Anaesthesia Cohort9,022 genotyped
Participants
17,025 patients
Outcome
CPSP, dichotomous (yes, no) or continuous (based on pain intensity, Brief Pain Inventory) across surgeries
Follow-up
3 months
Methodological detailsgenome-wide association analyses, polygenic risk scores
  • Genome-wide association analyses
  • Polygenic risk scores

Main finding

As reported in the abstract

Genetic loci associated with CPSP

Independent genome-wide significant loci associated with chronic postsurgical pain (CPSP)

16

SNP-based narrow-sense heritability, CPSP as continuous variable

13.7%

5.1–22.4%

Observational data: associations, not effects.

Further findings

Polygenic risk scores

PRS of post-traumatic stress disorder, pain all over the body, multisite chronic pain and opioid dependence associated with CPSP at nominal significance
