Background:
The aim was to ascertain the prognostic value of mid-regional pro-adrenomedullin (MR-proADM), measured within 24 hours from the onset of septic shock (SS).
Methods:
We performed a prospective, observational study on all patients admitted to our hospital's Intensive Care Unit with SS over a one year period from January to December 2011 to examine the outcomes in 100 consecutive SS cases. Demographic data and severity score (APACHEII and SOFA) were recorded. MR-proADM, C-reactive protein and procalcitonin were measured within the first 24 hours from SS onset. The outcome variable studied was 28-day mortality. Data were evaluated with non-parametric statistics bivariant and multivariate analyses for survival analysis.
Results:
In patients who died within 28 days (36%), MR-proADM, Lactate, APACHE II as well as SOFA were significantly higher compared with survivors. MR-proADM showed the best association with 28-day mortality, as well as a prognostic value (logrank test: P=0.0012). Statistical significance was also seen in the Cox regression analysis (P=0.0004) for all patients with a Relative Risk of 1.26 times that of the baseline for each mmol/L of increase in MR-proADM.
Conclusions:
In our study MR-proADM levels measured on admission correlates with 28-day mortality in patients with septic shock.
