Discontinuation of RAS inhibitors in CKD

Is discontinuation of RAS inhibitors associated with a significant difference in eGFR at 3 years in patients with advanced and progressive chronic kidney disease?

Study design: Multicenter, open-label, randomized controlled trial

Population:

  • Number of patients studied: 411
  • Inclusion criteria: Patients with advanced and progressive chronic kidney disease (eGFR, <30 ml per minute per 1.73 m2 of body-surface area)
  • Exclusion criteria: None specified

Interventions:

  • Experimental group: Discontinuation of RAS inhibitors
  • Control group: Continuation of RAS inhibitors

Primary outcome: eGFR at 3 years (excluding eGFR values obtained after the initiation of renal-replacement therapy)

Conclusion

Discontinuation of RAS inhibitors in patients with advanced and progressive chronic kidney disease was not associated with a significant between-group difference in the long-term rate of decrease in eGFR.
