Others
NO
1. To describe the kinetics of serum renin levels during the first 24 hours after vasopressor initiation in patients with hypotension treated in the intensive care unit (ICU).
2. To specify which renin value predicts 30-day mortality best among various variables deriving from six measurements during the 24 hours.
3. To visualize the trajectories of serum renin concentration and identify clinical phenotypes characterizing each trajectory.

Study Period
April 2025 (approval date)-June 2027
- Enrollment period: Until May 2026
- Follow-up period: Until June 2026
Inclusion Criteria
Participants must meet all of the following criteria:
1. Admitted to the ICU within 24 hours.
2. 18 years or older.
3. Receipt of continuous vasopressor infusion (norepinephrine, vasopressin, adrenaline, phenylephrine, or dopamine, alone or in combination).
4. Expected to stay in the ICU for more than 24 hours after enrollment.
Exclusion Criteria
Participants will be excluded if they meet any of the following criteria:
1. History of primary or secondary hyperaldosteronism.
2. Decision for aggressive palliative care.
3. Pregnancy or breastfeeding.
4. Decline to participate by the subject or their surrogate decision-maker.
5. Determination by the attending physician that study participation is inappropriate.
Study Design
A multicenter prospective cohort study.
Study Methods
This study targets adult patients in ICUs who require continuous intravenous infusion of vasopressors. Serum renin concentration will be measured six times within 24 hours of enrollment to elucidate its dynamics and validate its prognostic capability.
Primary Outcome
30-day mortality.
Secondary Outcomes
- ICU mortality.
- Major Adverse Kidney Events at 30 days (MAKE30: a composite outcome of mortality, dependency on renal replacement therapy [RRT], and persistent renal dysfunction).
- RRT dependency at 30 days.
- Persistent renal dysfunction at 30 days.
- Severe acute kidney injury within 7 days.
- Days alive and free from vasopressors at 30 days.
Statistical Analysis
Serum renin concentrations will be described as medians (interquartile ranges) at each measurement point. The main exposure variable will be the difference in serum renin concentration between 6 hours post-enrollment and baseline. Its association with the primary outcome, 30-day mortality, will be assessed using univariable and multivariable logistic regression analyses.
