Angiotensin-converting enzyme inhibitors and angiotensin receptor blockers (ACEi/ARBs) can cause acute kidney injury under dehydratation or in hemodynamically unstable conditions. Regarding kidney transplantation (KT), the risk of using ACEi/ARBs before surgery is not well established. Therefore, we evaluated the clinical outcomes to determine the effect of preoperative use of ACEi/ARBs on KT.
Methods
We retrospectively collected 1187 patients who received living-donor KT between January 2017 and December 2021. We conducted a propensity score-matched analysis between the ACEi/ARB(+) and ACEi/ARB(–) groups and evaluated the effects of ACEi/ARBs on delayed graft function, post-KT renal function, hyperkalemia events, rejection, and graft survival.
Results
The ACEi/ARB(+) group showed a similar incidence of delayed graft function as the ACEi/ARB(–) group (1.8% vs. 1.0%, P = 0.362). The risk of delayed graft function was not upregulated in the ACEi/ARB(+) group after propensity score-matching (odds ratio: 0.50, 95% confidence interval (CI) 0.13–2.00). Postoperative creatinine levels and the slope of creatinine levels after KT also were not significantly different between the two groups (creatinine slope from POD#0 to POD#7: – 0.73 ± 0.35 vs. – 0.75 ± 0.32 mg/dL/day, P = 0.464). Hyperkalemia did not occur more often in the ACEi/ARB(+) group than in the ACEi/ARB(–) group during perioperative days. Rejection-free survival (P = 0.920) and graft survival (P = 0.621) were not significantly different between the two groups.
Conclusions
In KT, the preoperative use of ACEi/ARBs did not significantly affect clinical outcomes including delayed graft function, postoperative renal function, hyperkalemia events, incidence of rejection, and graft survival rates compared to the patients who did not receive ACEi/ARBs.

WHO estimates that half of all patients worldwide are non-adherent to their prescribed medication. The consequences of poor adherence can be catastrophic, on both the individual and population level.
Join our expert panel to discover why you need to understand the drivers of non-adherence in your patients, and how you can optimize medication adherence in your clinics to drastically improve patient outcomes.
