  6. 6.

  12. 12. Clinical Characteristics of the Patients at Baseline, According to Subgroup Results
  13. 13. Results <ul><li>Mortality </li></ul><ul><ul><li>There was no significant difference between the two study groups in the primary outcome, the rate of death at 28 days among patients who did not have a response to corticotropin </li></ul></ul>Primary End Points <ul><ul><li>No differences in mortality were seen between the study groups or between the corticotropin subgroups at any other time point </li></ul></ul>
  14. 14. Mortality <ul><li>there was no significant difference among </li></ul><ul><li>Those who did not have a response to a corticotropin test </li></ul><ul><li>(Panel A) </li></ul><ul><li>Those who had a response to corticotropin (Panel B ) </li></ul><ul><li>All patients who underwent evaluation (Panel C) </li></ul>Results Kaplan–Meier Curves for Survival at 28 Days For the comparison between patients with septic shock who received hydrocortisone and those who received placebo
  15. 15. <ul><li>Reversal of Shock </li></ul>Secondary outcome The proportions of patients who underwent a reversal of shock were similar Among patients who did not have a response to corticotropin and in the placebo group (76.0%; 95% CI, 68.5 to 83.5) (70.4%; 95% CI, 61.8 to 79.0; P = 0.41) Among patients who had a response to corticotropin hydrocortisone group and in the placebo group (84.7%; 95% CI, 78.3 to 91.2) (76.5%; 95% CI, 69.3 to 83.6;P = 0.13) And among all patients
  16. 16. <ul><li>Reversal of Shock </li></ul>(Panel A) patients who did not have a response to a corticotropin test P = 0.06 (Panel B) patients who had a response to corticotropin P<0.001 (Panel C) all patients Kaplan–Meier Curves for the Time to Reversal of Shock For the comparison between patients with septic shock who received hydrocortisone and those who received placebo The duration of time until the reversal of shock was significantly shorter among patients receiving hydrocortisone for all patients (P<0.001), for those who had a response to corticotropin (P<0.001), and for those who did not have a response to corticotropin (P = 0.06)
  17. 17. MV The number of extubated patients on day 28 was similar in the two study groups Antibiotics There was no significant difference in outcome between study groups among patients receiving appropriate antibiotic therapy and those receiving inappropriate therapy Etomidate Among the 96 patients who had received Etomidate, 58(60.4%) did not have a response to corticotropin, as compared with 175 of 403 who did not receive etomidate (43.4%, P = 0.004) Results
  18. 18. Adverse Events <ul><li>In the hydrocortisone group, there was an increased incidence of superinfections </li></ul>including new episodes of sepsis or septic shock, with a combined odds ratio of 1.37 (95% CI, 1.05 to 1.79)
  19. 19. Adverse Events <ul><li>there was also an increased incidence of hyperglycemia and hypernatremia </li></ul>Neuromuscular weakness was rarely reported
  20. 20. Discussion <ul><li>In this study, the use of low-dose hydrocortisone had no significant effect on the rate of death in patients with septic shock at 28 days, regardless of the patients’ adrenal responsiveness to corticotropin </li></ul><ul><li>The proportion of patients in whom reversal of shock was achieved was similar in the two groups, though this goal was achieved earlier in patients who received hydrocortisone </li></ul><ul><li>This study showed an increased incidence of superinfection, including new episodes of sepsis or septic shock, in the hydrocortisone group </li></ul><ul><li>These results are in marked contrast to those of the study by Annane et al., in which both improved survival and reversal of shock were reported in patients with no response to corticotropin who received hydrocortisone plus fludrocortisone </li></ul><ul><li>The increased glucose levels in the hydrocortisone group may have contributed to increased mortality </li></ul>
  21. 21. In summary <ul><li>the use of hydrocortisone did not decrease mortality in a general population of patients with septic shock, even though the drug hastened reversal of shock </li></ul><ul><li>This lack of improvement may be related to an increased incidence of superinfection and new septic episodes </li></ul><ul><li>No benefit was seen in a subgroup of patients who had had no response to corticotropin, as was shown previously for patients with severe septic shock </li></ul>
  22. 22. Study recommendations <ul><li>Hydrocortisone cannot be recommended as general adjuvant therapy for septic shock (vasopressor responsive) </li></ul><ul><li>Corticotropin testing cannot be recommended to determine which patients should receive hydrocortisone therapy </li></ul><ul><li>Hydrocortisone may have a role among patients who are treated early after the onset of septic shock who remain hypotensive despite the administration of high-dose vasopressors (vasopressor unresponsive) </li></ul>
  23. 23. Editorials <ul><li>Encouraging results in small trials and then in a larger trial (Annane et al) led to previous recommendations to treat patients with septic shock with physiologic doses of hydrocortisone </li></ul><ul><li>The recommendations are based on five trials involving a total of 464 patients, of whom 265 (57.1%) died </li></ul><ul><li>A meta-analysis of these trials suggested that the use of corticosteroids reduced mortality </li></ul><ul><li>A metaanalysis that includes data from the CORTICUS trial is not likely to support the use of corticosteroids </li></ul><ul><li>And it seems clear that the corticotropin stimulation test does not identify patients who would benefit from corticosteroids </li></ul>
  24. 24. Editorials <ul><li>Clinicians who treat their patients with corticosteroids because they have observed a rapid reduction in the need for vasopressors should be aware that more rapid weaning from vasopressors is an unreliable surrogate outcome since it does not predict improved survival </li></ul><ul><li>To researchers it should be clear that substantial uncertainty over the role of corticosteroids persists. Reliable treatment recommendations will be possible only if a much larger trial is conducted. To avoid generating further uncertainty, the minimum sample size should substantially exceed the total number of patients who have been studied so far. The detection of a 15% reduction in relative risk from a rate of death of 35% will require a study of at least 2600 patients </li></ul>
  25. 25. International guidelines for management of severe sepsis and septic shock: 2008 <ul><li>Corticosteroids </li></ul>1. We suggest that intravenous hydrocortisone be given only to adult septic shock patients after it has been confirmed that their blood pressure is poorly responsive to fluid resuscitation and vasopressor therapy (grade 2C) 2.We suggest that the ACTH stimulation test not be used to identify the subset of adults with septic shock who should receive hydrocortisone (grade 2B) 3.We suggest that patients with septic shock should not receive dexamethasone if hydrocortisone is available (grade 2B) 4. We suggest the daily addition of oral fludrocortisone (50 mcg) if hydrocortisone is not available and the steroid that is substituted has no significant mineralocorticoid activity. Fludrocortisone is considered optional if hydrocortisone is used (grade 2C). 5. We suggest that clinicians wean the patient from steroid therapy when vasopressors are no longer required (grade 2D) . 6. We recommend that doses of corticosteroids comparable to 300 mg of hydrocortisone daily not be used in severe sepsis or septic shock for the purpose of treating septic shock (grade 1A) 7. We recommend that corticosteroids not to be administered for the treatment of sepsis in the absence of shock. There is, however, no contraindication to continuing maintenance steroid therapy or to using stress-dose steroids if the patient’s endocrine or corticosteroid administration history warrants (grade 1D)
