Relative Adrenal Insufficiency in Patients With Chronic Liver Disease: What Do We Know and How Is It Relevant in Critical Care Medicine

Systemic steroids in severe sepsis and septic shock

Despite more than 5 decades of study and debate, the role of corticosteroid treatment in patients with severe sepsis and septic shock remains controversial. Data support a beneficial effect on systemic blood pressure in patients with septic shock. However, the ability of corticosteroid therapy to improve mortality in patients with severe sepsis and septic shock remains controversial, with contradictory results from recent large multicenter clinical trials. Although it appears clear that high-dose corticosteroid treatment provides no benefit and possibly harm in septic patients, the experimental design flaws and biases of recent low-dose (physiologic) steroid treatment trials limit their ability to provide adequate answers to the important questions of which septic patients should be treated, how much steroid to give, and the optimum duration of treatment. Unfortunately, the answer to these important questions is not readily evident based on the current evidence or the application of metaanalysis to the available clinical data. This concise evidence-based review highlights the strengths and weaknesses of the current data to inform the practicing clinician as to which patients are likely to derive significant benefit from corticosteroid treatment, while we await more definitive guidance from future multicenter, prospective, randomized, controlled trials designed to better answer these important therapeutic questions.
