Adrenal insufficiency in prolonged critical illness.Wu JY, Hsu SC, Ku SC, Ho CC, Yu CJ, Yang PC Department of Internal Medicine, National Taiwan University Hospital, Chung-Shan South Road, Taipei, Taiwan 100, Republic of China. ccho1203@gmail.com. ABSTRACT: INTRODUCTION: Adrenal insufficiency is common in critically ill patients and affects their prognosis, but little is known about how adrenal function changes during prolonged critical illness. This study was conducted to investigate dynamic changes in cortisol levels in patients with critical illness who do not improve after treatment. METHODS: This observational cohort study was performed in the intensive care units of a university hospital. We studied acutely ill patients with initial cortisol level above 34 mug/dl, but who did not improve after treatment and in whom follow-up cortisol levels were determined during critical illness. All clinical information and outcomes were recorded. RESULTS: Fifty-seven patients were included. Ten patients had follow-up cortisol levels above 34 mug/dl, 32 patients had levels between 34 and 15 mug/dl, and 15 patients had levels under 15 mug/dl. Outcomes did not differ significantly among the three groups with different follow-up cortisol levels. In Cox regression analysis, those patients who survived to hospital discharge with second cortisol levels under 15 mug/dl had a longer hospital length of stay (odds ratio = 14.8, 95% confidence interval = 2.4 to 90.0; P = 0.004). CONCLUSION: The majority of acutely ill patients who remained in a critical condition had decreased serum cortisol levels. Depressed cortisol levels at follow up may lead to worse clinical outcomes. We propose that repeated adrenal function testing be conducted in patients with prolonged critical illness. Published 29 May 2008 in Crit Care, 12(3): R65.
