Clinical question in PICO format
In patients with septic shock, can corticosteroids, as compared to placebo, reduce mortality?
Evidence TableStudy, year,

Outcome measured
Results Comments
Spring, 2008 (CORTICUS)PMID: 18184957
RCT
499 patients with septic shock.47% with adrenal insuff (<9mcg cortisol increase after corticotropin test).
50 mg of intravenous hydrocortisone q 6 hrs for 5 days
mortality
Overall: steroid group 55% placebo 61% (P =.09) Adrenal normal: steroid group 29% placebo 29% (P =1.0)Adrenal insufficient: steroid group 39% placebo 36% (P =.69)
These patients were less sick than those in the Annane study (note difference in control group mortality).
Annane, 2002PMID: 17720019
RCT
300 pts, all ventilated.
76% with adrenal insuff (<9mcg cortisol increase after corticotropin test).
hydrocortisone (50 mg q 6 hrs) &fludrocortisone (50 mcg qd)
mortality
Overall: steroid group 55% placebo 61% (P =.09) Adrenal normal: steroid group 61% placebo 53% (P =.02)Adrenal insufficient: steroid group 53% placebo 63% (P =.02)
First study with sufficient power.
Cotreated with fludrocortisone.
Briegel, 1999PMID: 10321661
RCT
40 pts.
hydrocortisone 100 mg bolus, 0.18 mg/kg/hr(100 kg patient would receive 432 mg/d)
mortality
shock reversal
Mortality: steroids: 20% placebo 30%(insig)Shock reversal: steroids:90% placebo: 80%(insig)
Small size limits power
Bollaert, 1998PMID: 9559600
RCT
41 patients requiring pressors >48 hrs.
hydrocortisone 100 mg tid x5d
mortality Overall: steroids: 32% placebo: 63% (insig)Adrenal normal (n=29): steroids 33%
Introduced role of corticotropin testing - which did not predict response to steroids.
placebo 64%Adrenal insufficient (n=12): steroids 25% placebo 63%
29% were adrenal insufficient (<6mcg cortisol increase after corticotropin test)

Systematic review of RCTs
730 patients with septic shock in 6 studies
varying regimens
mortalityRR=1.07 (95% CI 0.91, 1.26)
Much heterogeneity
Lefering, 1995PMID: 7600840
Systematic review of RCTs
1329 patients in 10 studies.
varying regimens
mortalityARR=-0.2% (CI: -9.2, 8.8)
Much heterogeneity
No differences between low- vs. high-dose or type of corticosteroid.
The Gram-negative group demonstrated better outcome (-5.6% vs. 1.8% for gram positive).
Conclusions and recommendations1. The combination of a corticosteroids and a mineralocorticoid appear to enhance survival in patients with severe septic shock who are relatively adrenal insufficient.2. Ten such patients must be treated for one to benefit.3. In patients with septic shock and a normal adrenal gland, steroids may increase mortality.
