The Effectiveness and Safety of Corticosteroids Therapy in Adult Critical Ill Patients With Septic Shock: A Meta-Analysis of Randomized Controlled Trials

Efficacy and safety of corticosteroids in immunocompetent patients with septic shock

BACKGROUND

The use of corticosteroids in septic shock has been studied for many decades but yielded conflicting results. We conducted a systematic review to evaluate the efficacy and the safety of corticosteroids in immunocompetent patients with septic shock.

METHODS

Medline via PubMed, Cochrane Central Register of Controlled Trials (CENTRAL) in the Cochrane Library, and EMBASE were searched from inception to March 2020. Two reviewers independently identified randomized controlled trials (RCTs) comparing corticosteroids with a control group for immunocompetent patients with septic shock. Data were abstracted and reported following the Cochrane Handbook for Systematic Review of Intervention and Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement. The efficacy outcome included mortality and shock reversal. The safety outcomes were infection, gastrointestinal bleeding, and hyperglycemia.

RESULTS

Nine RCTs with a total of 1,298 patients were included. Compared with the control group, corticosteroid group did not lower the short-term (28 or 30 days) mortality (risk ratio [RR] 0.95, 95% confidence interval (CI) 0.85 to 1.06, inconsistency [I ²]=0%, trial sequential analysis [TSA]-adjusted CI 0.83 to 1.09, moderate-certainty evidence). Corticosteroids significantly shortened the time to shock reversal compared with the control group (mean difference [MD] -21.56 hours; 95% CI -32.95 to -10.16, I ²=0%; TSA-adjusted CI -33.33 to -9.78, moderate-certainty evidence). The corticosteroid treatment was associated with an increased risk of hyperglycemia but not the infection or gastrointestinal bleeding.

CONCLUSIONS

The corticosteroid treatment is not associated with lower short- or long- term mortality compared with placebo in immunocompetent patients with septic shock. However, corticosteroids significantly shorten the time to shock reversal without increasing the risk of infection. The patient's immune status should also be considered during clinical treatment and clinical trials in future.

Are Corticosteroids Beneficial for Sepsis and Septic Shock? Based on Pooling Analysis of 16 Studies

Background: A host of systematic reviews and meta-analyses were carried out to estimate the role of corticosteroids in sepsis and septic shock. Discordant opinions were investigated to determine whether patients who experienced sepsis and septic shock could benefit from corticosteroids treatment. Our purpose is to perform a systematic review of overlapping meta-analyses, to explore the role of corticosteroids in the treatment of sepsis and septic shock.

Method: Ovid MEDLINE, EMBase, Cochrane Database of Systematic Reviews, and LILACS were searched for eligible studies. Two authors individually extracted the relevant data and evaluated the quality of the meta-analysis using A MeaSurement Tool to Assess systematic Reviews 2 (AMSTAR 2) and ROBIS. The Jadad decision algorithm was implemented to identify the meta-analyses that offered the optimal level of evidence.

Result: Sixteen meta-analyses met the eligibility criteria. None of the studies that reported mortality illustrated a significant improvement on mortality (14-day and 90-day), but a 28-day mortality on a long course of a low dose corticosteroids was described. Only four studies stated that a long course of low-dose corticosteroids had advantageous effect on 28-day mortality. A meta-analysis by Fang et al. was regarded as the highest level of evidence in the Jadad decision algorithm among the meta-analyses that were investigated in this systematic review.

Conclusion: The 28-day mortality was reduced, as well as the mortality in the ICU and hospital and the length of stay in the ICU, using a long course of low-dose corticosteroids. This was demonstrated by a meta-analysis of the current optimal available evidence. Additionally, significant improvements on the adverse events of hyperglycemia and hypernatraemia have been made.

Reevaluating the Role of Corticosteroids in Septic Shock: An Updated Meta-Analysis of Randomized Controlled Trials

What Is Known and Objective. To reevaluate the benefits and risks of corticosteroid treatment in adult patients with septic shock. Methods. This study was performed based on PRISMA guidelines. Randomized controlled trials (RCTs) of corticosteroids versus placebo were retrieved from PubMed, MEDLINE, EMBASE, Web of Science, the Cochrane Central RCTs, and ClinicalTrials.gov from January 1980 to April 2018. We also conducted a trial sequential analysis to indicate the possibility of type I or II errors and calculate the information size. Grading of Recommendations, Assessment, Development and Evaluation approach (GRADE) was applying to assess the certainty of evidence at the primary outcome level. Results. Twenty-one RCTs were identified and analyzed. Patients treated with corticosteroid had a 7% reduction in relative risk in 28-day all-cause mortality compared to controls (RR 0.93, 95% CI 0.88 to 0.99). However, there were no significant differences for the intensive care unit (ICU) mortality (RR 0.97, 95% CI 0.86 to 1.09) or in-hospital mortality (RR 1.01, 95% CI 0.92 to 1.11). Corticosteroids shortened the length of ICU stay by 1.04 days (RR -1.04, 95% CI -1.72 to -0.36) and the length of hospital stay by 2.49 days (RR -2.49, 95% CI -4.96 to -0.02). Corticosteroids increased the risk of hyperglycemia (RR 1.11, 95% CI 1.06 to 1.16) but not gastroduodenal bleeding (RR 1.06, 95% CI 0.82 to 1.37) or superinfection (RR 1.04, 95% CI 0.94 to 1.15). However, some date on secondary outcomes were unavailable because they were not measured or not reported in the included studies which may cause a lack of power or selective outcome reporting. The information size was calculated at 10044 patients. Trial sequential analysis showed that the meta-analysis was conclusive and the risk of type 2 error was minimal. What Is New and Conclusion. Corticosteroids are likely to be effective in reducing 28-day mortality and attenuating septic shock without increasing the rate of life-threatening complications. TSA showed that the risk of type II error in this meta-analysis was minimal and the result was conclusive.

A Canadian survey of critical care physicians' hemodynamic management of deceased organ donors

PURPOSE

We sought to characterize Canadian physicians' perspectives and stated practices regarding their hemodynamic care of deceased organ donors.

METHODS

We designed a 24-item electronic survey that was independently pretested for relevance, clarity, and intra-rater reliability by ten critical care clinicians. With the help of provincial organ donation organizations (ODO), we identified intensive care units (ICUs) with a high volume of adult deceased donors (defined by the management of five or more donors per year for two consecutive years). Medical directors of these high-volume ICUs helped identify ICU physicians to whom our survey was emailed.

RESULTS

Of the 448 ICU physicians from 37 centres in nine provinces that were emailed, 184/448 (41.1%) responded to one or more survey questions. Respondents identified specialist nurses from ODOs as their primary source of guidance in donor care (107/165; 60%). They typically diagnosed an autonomic storm according to a rise in blood pressure (159/165; 96.4%) and/or heart rate (135/165; 81.8%); nevertheless, their stated management varied substantially. After termination of the autonomic storm, preferred first-line vasopressors were norepinephrine (93/164; 56.7%) and vasopressin (68/164; 41.5%). Twenty-one respondents (21/162; 13.0%) reported that they never administer inotropes to donors. Corticosteroid and thyroid hormone prescriptions for all donors was reported by 62/161 (37.6%) and 50/161 (31.1%) respondents, respectively. Respondents perceived an influence from ODO nurses or transplant physicians when prescribing corticosteroids (77/161; 47.8%) and/or thyroid hormones (33/161; 20.5%) CONCLUSION: We observed important variability in self-perceived practices of ICU physicians in the hemodynamic management of deceased donors, particularly in the treatment of the autonomic storm, in the prescription of hormone therapy, and in the administration of inotropes.
