Perhaps when we do find it we may be able to alter and influence the underlying pathophysiology of sepsis. Many reports from those who believe that this may lie in the hypothalamic-pituitary-adrenal axis have recently been published. Manglik and colleagues 1 looked into secondary adrenocortical insufficiency in patients who present with severe sepsis. Measuring maximal cortisol secretion after stimulation with adrenocorticotrophic hormone those investigators found that 9 of their population failed an adrenocorticotrophic hormone stimulation test. Four per cent had previously undiagnosed pituitary disease and 5 were suffering from sepsis-related adrenal dysfunction. They used absolute cortisol levels and not delta cortisol to define adrenocortical insufficiency but until we have an established definition for adrenocortical insufficiency in sepsis the studies will continue to yield disparate results. Looking at reduced endogenous steroid levels in sepsis Marx and coworkers 2 focused on the androgens dehydroepiandrosterone DHEA and its sulphated precursor DHEAS and looked at disparity between survivors and nonsurvivors from severe sepsis. The cortisol levels of survivors reached upper normal limits and decreased significantly toward late sepsis. However nonsurvivors had persistently lower cortisol levels but within the normal .
