Introduction: Scoring systems can be used to predict the risk of mortality and outcomes in critically ill patients. Acute kidney injury (AKI) is one of the strongest factors negatively influencing patient outcomes. Midregional proadrenomedullin (MR‑proADM) shows promising results as an outcome predictor in patients with sepsis.

Objectives: We aimed to evaluate the value of MR‑proADM in incident AKI and mortality prognostication among patients admitted to the intensive care unit (ICU) in comparison with commonly used scoring systems.

Patients And Methods: Our study included a single‑center cohort of 77 patients admitted to the ICU. Plasma MR‑proADM levels were measured within 24 h of admission. The Acute Physiology and Chronic Health Evaluation II (APACHE II) and the Sequential Organ Failure Assessment (SOFA) scores were used as a reference. The primary endpoints were incident AKI and in‑hospital mortality.

Results: Patients who died during hospitalization period had a higher MR‑proADM concentrations as compared with patients who survived (2592.5 pg/ml vs 995.3 pg/ml; P <0.001). The levels of MR‑proADM correlated positively with the APACHE II or SOFA score (r = 0.3; P = 0.004 and r = 0.3; P = 0.008, respectively). In the receiver operating characteristics analysis, MR‑proADM concentration was superior to both scoring systems (P = 0.002 and P = 0.001, respectively). In univariate logistic regression, MR‑proADM was associated with in‑hospital mortality (odds ratio [OR], 1.22; 95% CI, 1.11-1.35 per 100 pg/ml increase of MR‑proADM) and after adjusting for multiple variables remained an independent predictor of death (OR, 1.35; 95% CI, 1.22-1.49 per 100 pg/ml increase of MR‑proADM). MR‑proADM was not useful in predicting incident AKI.

Conclusions: MR‑proADM can be applied in clinical practice as a prognostic tool for mortality but not incident AKI in the general ICU population with at least similar accuracy as APACHE II and SOFA scores.
