Abstract

GLP1R agonist use is associated with a 2.32-fold increased risk of chronic .

  • analysis indicates a significant causal relationship between GLP1RA use and chronic tubulo-interstitial nephritis (CTIN).
  • No significant association was observed for acute tubulo-interstitial nephritis (ATIN).
  • Colocalization analysis supports the genetic link between GLP1R expression and CTIN, with a high probability of shared genetic variants.
  • Four plasma proteins (HYAL1, NMNAT1, IL12RB2, and DPP6) were identified as partial mediators of the effect.
