Background: Previous trials evaluated the incidence of critical illness-related corticosteroid insufficiency (CIRCI) using 250 μg adrenocorticotropic hormone (ACTH). However, this supraphysiological dose could result in false-positive levels. We aimed to determine the incidence of CIRCI in septic patients using a 1 μg ACTH stress test. ⋯ In addition, the CIRCI group had a shorter time to develop AKI and a higher probability of developing AKI (4 days and 44.6%, respectively) in comparison with the non-CIRCI group (6 days and 45.57%, respectively). Conclusion: We concluded that the CIRCI group had a lower mean survival rate and a higher incidence of AKI. We recommend the use of 1 μg ACTH test in septic shock patients to identify this subgroup of patients.

Observational Study
Identification of an optimal threshold to define oliguria in critically ill patients: an observational study.
The relevance of current consensus threshold to define oliguria has been challenged by small observational studies. We aimed to determine the optimal threshold to define oliguria in critically-ill patients. ⋯ The widely used cut-off for oliguria of 0.5 ml/kg/h over 6 h may be too conservative. A cut-off of 0.2 ml/kg/h over 3 or 6 h is supported by the data and should be considered in further definitions of oliguria.
