Sumario: | : Context: Hydrocortisone administration in septic shock remains controversial. Corticosteroid-binding globulin (CBG) transports cortisol to inflammatory sites and is depleted in septic shock. OBJECTIVE: To determine if severely deficient plasma CBG <200 nmol/L (Ref range 269-641 nmol/L) independently predicts septic shock mortality. METHODS: A prospective observational study in patients with septic shock. Patients were categorised into two groups: mean plasma CBG concentrations <200 nmol/L and ≥200 nmol/L (day 1/2), with additional categorisation by nadir CBG. Primary outcome was Intensive Care Unit (ICU) mortality. Secondary outcomes were 28- and 90-day mortality, norepinephrine requirements, renal-replacement therapy, and clinician-instituted hydrocortisone. RESULTS: 135 patients were included. Mortality rates in ICU were higher in the CBG <200 nmol/L vs the CBG ≥200 nmol/L group: 32.4% vs 13.9%; Odds ratio (OR), 2.97, (95% confidence intervals (CI) 1.19,7.41); P=0. 02: 28-days; OR 2.25 (95% CI 0.99,5.11): 90-days; OR 2.21 (95% CI 0.99,4.91). Multivariate analysis revealed 4 factors independently associated with ICU mortality: CBG <200 nmol/L (OR 3.23, 95% CI 1. 06,9.88), Acute Physiology and Chronic Health Evaluation (APACHE) II >25 (OR 3.58, 95% CI 1.20,10.68); Sequential [Sepsis-related] Organ Failure Assessment (SOFA) liver score (OR 1.98, 95% CI 1. 04,3.72); and renal-replacement therapy (OR 6.59, 95% CI 2.17,20. 01). Nadir CBG levels were associated with higher SOFA cardiovascular scores, norepinephrine total dose (ug) P<0. 01 and duration (days) P<0. 01. Plasma cortisol concentrations and hydrocortisone administration did not relate to ICU mortality. CONCLUSION: Septic shock patients with CBG <200 nmol/L had higher norepinephrine requirements and 3.2-fold higher ICU mortality. CBG concentration was the only directly reversible independent mortality risk factor. Presentation: No date and time listed |
