Glomerular filtration rate in patients with type 2 diabetes mellitus: is serum isthmin-1 level a possible link?

BMJ Open Diabetes Res CarePublished Retrospective study

Authors' conclusion

Serum Ism-1 levels were inversely associated with eGFR, and high Ism-1 levels may be used as a potential biomarker for predicting kidney function impairment in patients with T2DM.

Study context

Population
Patients with T2D
Participants
209 patients
Exposure
Decreased estimated glomerular filtration rate (eGFR) vs normal eGFR
  • Decreased eGFRn = 42
  • Normal eGFRn = 167reference
Outcome
Relationship between serum isthmin-1 (Ism-1) levels and glomerular filtration rate (GFR)

Main finding

As reported in the abstract

Serum Ism-1 and eGFR

OR of eGFR <60 mL/min/1.73 m² per 0.1 ng/mL increment of Ism-1 (p<0.001)

1.545

ROC: AUC of Ism-1 >1.297 ng/mL for eGFR <60 mL/min/1.73 m²

0.908

Observational data: associations, not effects.
