[Nhiễm trùng] Steroid trong sốc nhiễm trùng

Clinical Question:

We tend to think of sepsis as this kind of bag where we throw in fluids, vasopressors and antibiotics early so we can improve outcomes. Should steroids be included? What is the evidence that shows that steroids work in septic shock?

Background:

1. Mineralocorticoids increase blood volume and help with vascular tone. Both effects would certainly be helpful in patients who are having increased permeability at the vascular level.
2. Corticosteroids decrease pro-inflammatory cytokines while increasing anti-inflammatory cytokines. Effects that would certainly help with inflammation.
3. Sepsis decreases the activity of the hypothalamic-pituitary-adrenal (HPA) axis. So there is thought to be a relative adrenal insufficiency, especially in severe septic shock. So steroids should help, theoretically.

Evidence:

1. A study of 300 patients by Annane et. al. in 2002 compared the addition of hydrocortisone and fludrocortisone vs. placebo. In patients who were nonresponders to corticotropin stimulation, hydrocortisone and fludrocortisone for 7 days showed a decrease in mortality.¹
2. The CORTICUS study group in 2008 found that if you jumped on patients early with steroids, there were no benefits. However, these patients were thought to not be as sick. Maybe if we gave steroids to patients with sepsis that was more severe, we could prevent them from going into severe septic shock.²
3. In the HYPRESS RCT, patients were given hydrocortisone before they went into septic shock. They didn’t find any benefit of steroids in preventing patients from developing severe septic shock.³
4. The ADRENAL trial in 2018 looked at the effect of hydrocortisone in 3658 patients. They gave one group a hydrocortisone infusion of 200mg/day and they gave the other group placebo. They found no significant difference between the groups in terms of 90-day mortality. However, when assessing patient-centered outcomes they found: a) a faster resolution of shock and b) shorter duration of initial episode of mechanical ventilation.⁴

“So patient centered outcomes vs mortality, there’s a conundrum, what do we do. What are we basing our treatment off of? This study really showed that there was no real harm to giving steroids, there’s just no difference in terms of mortality. There is a caveat to this, the study actually said you had to give a 200mg/day as an infusion, as opposed to typical stress dose steroids of 100mg q8hrs. Someone said well, maybe the ADRENAL study isn’t the end-all-be-all.”

Enter the APROCCHSS study: This study looked at fludrocortisone, hydrocortisone, and activated protein C vs. placebo. When activated protein C was withdrawn from the market for safety concerns, they continued the study with two groups: one received hydrocortisone plus fludrocortisone and the other received placebo. They studied 1241 patients and found that 90-day mortality was significantly lower in the hydrocortisone plus fludrocortisone group. Additionally, other outcomes were also positive: more vasopressor-free days and organ-failure-free days. In this study, the number of ventilator-free days was similar between the two groups.⁵

“But again there are caveats:

1. The addition of fludrocortisone. There was no comparison between hydrocortisone and fludrocortisone, it was just both vs placebo.
2. Fludrocortisone doses used was 50µg, which is a really low dose.”

Although the mortality benefit is questionable, when considering patient-centered outcomes, there is potential utility. It is undeniable that we want our patients to have a faster reversal of shock, less days on a ventilator, less days on pressors and less days in the ICU.

Conclusion:

“I say: certainly, if the patient has risk of adrenal insufficiency due to chronic steroid therapy, it’s a no brainer, make it happen. If the patient is requiring multiple doses of pressors, you’re starting to max out your norepinephrine and you’re starting to think maybe I should add a second or third pressor. In order to get them off of those pressors faster and out of shock, I would give them a stress dose of steroids. And I am using hydrocortisone and not fludrocortisone.”
