Abstract
INTRODUCTION. At the moment, assessing adrenal dysfunction in critical patients and ways to correct this function with hormone replacement therapy are extremely difficult. OBJECTIVES. Analysis of changes in the dynamics of ACTH and cortisol levels in blood plasma during ECMO. MATERIALS AND METHODS. The prospective study was performed in intensive care unit (47 patients on ECMO). After connecting ECMO (D0), (D1–D3–D5–D7–D9), and until the completion of ECMO, assessment of cortisol and ACTH levels was carried out. RESULTS. The median level of cortisol in blood plasma was higher in the non-survivors patients on the third day (D3) (p = 0.05), D7 (p = 0.03); D13 (p = 0.05) and the last day of observation (p = 0.001), respectively. The level of ACTH in the blood of non-survivors patients was higher immediately on the day of ECMO initiation (D0) and on day 3 (D3) of observation: D0 (p = 0.018); D3 (p = 0.04), respectively. Analysis of the ROC curve showed that cortisol levels show a sensitivity of 71 % and a specificity of 89 % to an adverse outcome during ECMO. DISCUSSION. The life-saving ECMO technique, in critical conditions, is associated with a high risk of increasing of complications, including potentially lethal ones. Critical illness-related corticosteroid insufficiency (CIRCI) clinically manifests itself as inadequate adrenal activity, taking into account the augmentation of the disease severity. This activity is expressed in the form of a decrease in production and/or resistance to endogenous cortisol, as confirmed by the study. Consideration of CIRCI during the usage of ECMO reflects more objectively the violation of the pituitary-adrenal system. CONCLUSIONS. 1. CIRCI is detected in patients during ECMO. 2. High plasma cortisol levels are the predictor of an adverse outcome. 3. The level of ACTH in blood plasma is higher in patients with adverse outcomes. 4. High levels of cortisol in plasma are not a criterion for making the decision to initiate hydrocortisone therapy.
