A Prompt REstart Study of Renin-Angiotensin System Inhibitors After Acute Kidney Injury (APRES-AKI)
The goal of this pilot clinical trial is to learn if early restart of renin-angiotensin system inhibitor (RASi) medications is feasible and well-tolerated in hospitalized patients with acute kidney injury (AKI). Researchers will compare early RASi restart to usual care.
Study participants will restart RASi per study protocol, obtain a lab test in 1-2 weeks if RASi restarted in the hospital and not collected as part of routine care, and answer questions at the 90-day follow-up.

Detaillierte Beschreibung
Among at-risk patients with heart failure and chronic kidney disease, use of RASi medications decreases the subsequent risk of adverse events such as cardiovascular death and kidney disease progression. However, RASi treatment is often stopped when AKI is detected in the hospital based on the notion that restoring an intact renin-angiotensin system in the context of hypovolemia or hypotension may be helpful to maintain perfusion to the glomeruli and thus support the glomerular filtration rate.
In observational studies, restart of RASi medications among at-risk patients after AKI has been associated with decreased subsequent rates of mortality, cardiovascular events, and kidney disease progression. However, there is no rigorous evidence from randomized trials to guide optimal strategy of RASi restart after AKI.
This is a pilot trial among hospitalized patients with AKI whose RASi were held to investigate the feasibility and tolerability of a strategy of early RASi restart (n=30) compared to usual care (n=30). This pilot trial will provide valuable data critical to inform the design of a larger definitive trial.
The study hypothesis is that the strategy of early RASi restart after AKI is feasible and well-tolerated. This pilot trial will inform the design of a larger definitive trial to determine whether early RASi restart can increase rates of RASi use at 90 days compared to usual care.

Experimental: Early RASi restart strategy
The early restart strategy is to resume RASi as soon as the serum creatinine (SCr) downtrends by ≥0.3mg/dL from peak.
In addition, the following criteria must be met: most recent potassium ≤5mEq/L, SCr-based eGFR reported as ≥15 mL/min/1.73m2,
and average systolic blood pressure≥120mmHg 12 hours prior to restart.
If the study participant is discharged from the hospital before the RASi restart criteria are met, management of RASi restart would be deferred to the discretion of longitudinal outpatient healthcare team.
