*Purpose: The impact of chronically administered medications for renin-angiotensin-aldosterone blockade (e.g. ACE-I, ARB), taken prior to kidney transplant (KTx), on immediate allograft function is unknown.
*Methods: A single center retrospective chart review was conducted on consecutive adult KTx or kidney-pancreas (KP) recipients transplanted between 12/2018- 6/2019. Patients were compared according to the use of an ACE-I/ARB vs none in the immediate pre-transplant period. No patients were maintained on ACE-I/ARB after KTx. Exclusion criteria were: HIV infection, extra-renal transplants other than KP, history of FSGS, all-cause graft loss < 30 days. Allograft function was analyzed within the first wk post-transplant to assess DGF incidence, serum creatinine (SCr) levels, and incidence of hyperkalemia (defined as potassium level > 5.5 mmol/L). Use of an ACE-I/ARB was assessed by documentation in an admission medication reconciliation completed by a pharmacist.
*Results: Of 119 recipients assessed, 48 (40%) had an ACE-I/ARB documented on an admission medication reconciliation. Key demographics were similar between the groups (Table 1) (p=NS), including deceased donation rates, KDPI scores, and cold ischemia times. DGF occurred in 6 (12.5%) recipients in the ACE-I/ARB cohort, and 17 (23.9%) recipients in the no ACE-I/ARB group (p=NS). Change in SCr from pre-transplant baseline during the first post-transplant week for both groups is shown in Figure 1 (excluding DGF patients) (p=NS). Hyperkalemia occurred in 9 (19%) of the ACE-I/ARB patients and 17 (24%) of the non-ACE-I/ARB group (p=NS), mostly within the first 24 hours post-transplant (44% vs 65%, p=NS).
*Conclusions: Recovery of kidney function and serum potassium levels after transplant do not appear to be adversely impacted in recipients taking ACE-I/ARB therapy immediately prior to KTx, compared to recipients not taking these medications. Based on our results, identification of ACE-I/ARB therapy during pre-transplant pharmacy medication reconciliation may not impact immediate graft function after KTx.
