Subphenotype-Dependent Benefits of Bariatric Surgery for Individuals at Risk for Type 2 Diabetes

Diabetes CarePublished Cohort study

Authors' conclusion

Participants in C5 had the highest benefit from bariatric surgery in terms of improvement in insulin resistance, β-cell function, and prediabetes remission. This novel classification might help identify individuals who will benefit specifically from bariatric surgery.

Study context

Population
Individuals without T2D but at risk for T2D (elevated BMI), with normal glucose regulation or prediabetes (ADA criteria), undergoing bariatric surgery; discovery cohort Lille, France; replication cohort Rome, Italy; control cohort Tübingen, Germany
Participants
121 / 180 / 503
Exposure
Bariatric surgery outcomes across Tübingen Clusters C4, C5 and C6
  • C4n = 121
  • C5n = 180
  • C6n = 503
Outcome
Alteration of glucose regulation parameters and prediabetes remission
Methodological detailsdiscovery and replication cohorts, control cohort with behavioral modification counseling
  • Discovery and replication cohorts
  • Control cohort with behavioral modification counseling

Main finding

As reported in the abstract

  • Relative body weight loss similar among all clusters
  • Reduction of insulin resistance and improvement of β-cell function strongest in C5
  • Prediabetes remission rate lowest in low-risk C4 and highest in high-risk C5

Observational data: associations, not effects.

Further findings

Cluster change

Individuals from high-risk clusters changed to low-risk clusters in both bariatric surgery cohorts but not in the control cohort
