ABSTRACT
Corticosteroids have been considered for decades for the treatment of severe sepsis
and septic shock, based on their pivotal role in the stress response and their hemodynamic
and antiinflammatory effects. Whereas short-term therapy with high doses of corticosteroids
(up to 42 g hydrocortisone equivalent for 1-2 days) has been ineffective or potentially
harmful, prolonged therapy with lower doses (200-300 mg hydrocortisone for 5-7 days
or longer) in septic shock has recently revealed beneficial effects in several randomized,
controlled trials. Assuming relative adrenal insufficiency (RAI) and peripheral cortisol
resistance, treatment with low-dose hydrocortisone improved shock reversal, reduced
inflammation, and improved outcome. Shock reversal and reduction of mortality were
more effective in patients with RAI, and most significant in patients with severe
shock. Diagnosis of RAI with corticotropin tests in septic shock, however, is highly
dependent on cut-off values and definition of RAI. Thus, it is not clear yet which
patients benefit most from low-dose hydrocortisone and if treatment should be restricted
to patients with RAI. In addition the role of fludrocortisone is uncertain. Nevertheless,
based on current data, low-dose hydrocortisone therapy should definitely be considered
in vasopressor-dependent septic shock. This review will address some critical points.
