Data about the safety of ACEI/ARB use in early (<3 months) posttransplant period are restricted and remain controversial.
This systematic review and meta-analysis included searches of PubMed, Embase and CENTRAL from inception to 31 November 2023, for studies to compare the safety (transplant outcomes and postoperative complications) of ACEI/ARB with non-ACEI/ARB (other antihypertensive medications) initiation in early post kidney transplant period.
Of 1,247 citations identified, 13 eligible studies involving 1919 patients were enrolled for analyses. In short- or long-term observations, there were no differences on pooled serum creatinine between ACEI/ARB and non-ACEI/ARB groups whether initiated within 1 or 1–3 months posttransplant, however, initiation of ACEI/ARB within the first month posttransplant had an advantage effect on the mean creatinine clearance. Early initiation of ACEI/ARB posttransplant reduced the risks of patient death (RR 0.60,
Early initiation of ACEI/ARB within 3 months posttransplant proved to be basically safe and has renal function recovery benefits, however, hyperkalemia needs to be noted.
