adrenal insufficiency in critical ills patients

Endocrine emergencies are underdiagnosed and often overlooked amid the management of severe multisystem pathologies in critically ill patients in the medical intensive care unit (ICU). In an appropriate clinical scenario, a low threshold of suspicion should be kept to investigate for various life-threatening, yet completely treatable, endocrinopathies. Prompt identification and treatment of endocrine emergencies such as diabetic ketoacidosis, myxedema coma, thyroid storm, and/or adrenal insufficiency leads to fewer complications, shorter ICU and hospital stay, and improved survival...

UNLABELLED: Hyponatremia is defined as serum sodium concentration less than 135meq/l. More severe symptoms are seen when serum sodium falls below 120 meq/l. Hyponatremia in ICU is a very common scenario. Treatment strategy is decided after thorough history taking and clinical examination. Judicious treatment is necessary as rapid correction and delayed correction both can lead to various neurological sequelae. This study was done on critically ill patients who had hyponatremia on the day of admission and clinical and aetiological profile was studied...

UNLABELLED: Adrenal insufficiency (AI) is well entrenched in medical constraints like septic shock, critically ill and multi-morbid hemodynamically unstable patients but its exact prevalence or differences in the cases of chronic liver disease (CLD) at variable grades of severity has recently gained momentum. The eventuality of AI propounding in stable compensated and decompensated cirrhosis without sepsis or in early and late stages of liver desecration are the existing lacunae in popular literature that this study aims to address...

BACKGROUND Waterhouse-Friderichsen syndrome, also known as acute adrenal insufficiency due to adrenal gland hemorrhage, is an uncommon and frequently fatal condition classically presenting with fever, shock, rash, and coagulopathy. Although most often associated with Meningococcemia, many other etiologies have been implicated, including reports of Staphylococcus aureus infection on autopsy examinations. This report details an adult intravenous drug user with adrenal hemorrhage associated with methicillin-resistant Staphylococcus aureus (MRSA) bacteremia...

Critical illnesses are hallmarked by increased systemic cortisol availability, a vital part of the stress response. Acute stress may trigger a life-threatening adrenal crisis when a disease of the hypothalamic-pituitary-adrenal (HPA) axis is present and not adequately treated with stress doses of hydrocortisone. Stress doses of hydrocortisone are also used to reduce high vasopressor need in patients suffering from septic shock, in the absence of adrenal insufficiency. Research performed over the last 10 years focusing on the HPA axis during critical illness has led to the insight that neither of these conditions can be labeled "critical illness-induced corticosteroid insufficiency" or CIRCI...

BACKGROUND: Tuberculosis (TB) is a chronic infectious disease, common in China. TB bacteria can invade multiple organs throughout the body, but they rarely cause critical illness. We present a complex critically ill case in this report. CASE PRESENTATION: A 40-year-old man suffered sudden cardiac arrest during an emergency room visit. Spontaneous circulation resumed after emergency cardiopulmonary resuscitation (CPR), but recurrent ventricular fibrillation and refractory cardiac shock emerged...

BACKGROUND: Coronavirus disease 2019 (COVID-19) manifestations varied completely from its time of emergence. However, the assessment of adrenal insufficiency (AI) in this pandemic is lacking. In this review, we aimed to evaluate the status of AI among COVID-19-infected individuals. METHODS: A systematic literature screening in PubMed/MEDLINE, Scopus, and Web of Science was performed until May 23, 2021. We collected relevant published peer-reviewed studies that reported AI occurrence in patients who suffered from COVID-19...

About 3.4% of the hospitalized tubercular patients need admission to the intensive care unit (ICU). Patients requiring ICU admission had a poor prognosis and high mortality rate (60 vs 25%) as compared to other causes of severe pneumonia. The most common indication for tuberculosis-related ICU admission is acute respiratory failure due to pneumonia or acute respiratory distress syndrome (ARDS) (with or without miliary tuberculosis) followed by septic shock with multiple organ dysfunction, adrenal insufficiency, and neurological involvement, especially tubercular meningitis...

The "fight or flight" response to critical illness relies on increased cortisol availability, traditionally attributed to several-fold-increased cortisol production via hypothalamus-pituitary-adrenal-axis activation. Recent studies provided evidence against this concept with clinical implications. First, high cortisol availability during critical illness is driven by suppressed cortisol binding and reduced cortisol breakdown rather than increased cortisol production. This implies reduction of hydrocortisone doses when prescribed in ICU...

Cushing's syndrome causes increased morbidity and mortality due to cardiovascular and infectious diseases. Exogenous Cushing's syndrome can render the adrenal glands unable to cope with severe infections and may result in Addisonian crisis, which can be fatal if not properly diagnosed and treated. During hospitalization for disease exacerbation, a man on chronic glucocorticoid therapy for Crohn's disease and Cushingoid features developed polymicrobial septic shock together with hypotension that was unresponsive to fluids...

BACKGROUND & AIMS: Relative adrenal insufficiency (RAI) in patients with cirrhosis is associated with increased mortality. Although the pathogenesis of RAI remains unclear, disordered cholesterol metabolism may contribute. METHODS: We performed a prospective cohort study of 96 non-critically ill subjects with decompensated cirrhosis at a tertiary care center. Subjects were administered 250µcg cosyntropin, with RAI defined as an increase in total cortisol < 9 µg/dL...

BACKGROUND & AIMS: Hepatic enzymes play a major role in the metabolic elimination of cortisol, and reduced rates of cortisol clearance have been consistently observed in patients with chronic liver disease. It is less clear whether there are concomitant abnormalities of adrenocortical function in patients with cirrhosis. In the present study, we sought to assess adrenocortical function in patients with cirrhosis using measures of free cortisol appearance and elimination rates that are independent of serum concentrations of cortisol binding proteins...

BACKGROUND: Relative adrenal insufficiency (RAI) is frequently found in patients with liver cirrhosis, especially in critically ill conditions. However, the prognostic impact of RAI in non-critically ill cirrhosis remains controversial. The aim of the present study was to assess the prevalence of RAI and its prognostic implication in non-critically ill cirrhotic patients. METHODS: From December 2015 to November 2017, hospitalised non-critically ill cirrhotic patients admitted with hepatic decompensation were prospectively enrolled in this study...

BACKGROUND: Critical illness-related corticosteroid insufficiency (CIRCI) is common during critical illness and is usually associated with poor outcomes, as prolonged duration of mechanical ventilation (MV) and higher mortality. CIRCI may alter cardiac and vascular functions. Weaning-induced pulmonary oedema (WiPO) is a major mechanism of weaning failure. The aim of this study was to evaluate the role of CIRCI in patients with difficult ventilator weaning and its possible relation with WiPO...

After a stressful event, adaptative mechanisms are carried out to support vital functions. Hypothalamic-pituitary-adrenal axis plays a key role in stress response regulating metabolism, cardiovascular function and immune system. This review addresses pathophysiological changes of the adrenal axis during critical illness, recognizing limitations of methods applied for its evaluation in this special context and defining indications for corticosteroid replacement in critically ill patients. The concept of relative adrenal insufficiency should be abandoned; cosyntropin stimulation test should not be performed for diagnosis of adrenal insufficiency in critical illness nor for establishing the need of treatment...

BACKGROUND: The diagnosis of adrenal insufficiency in pregnancy is relatively rare. Further, making this diagnosis can be challenging as many of the symptoms overlap with normal symptoms of pregnancy. Given the potential for severe maternal and fetal morbidity and mortality, early recognition and prompt comprehensive treatment are critical. CASE: A 24-year-old woman, G3 P2002, at 17 + 1 weeks of gestation with unremarkable prenatal course was admitted to hospital for hyperemesis gravidarum in the setting of parainfluenza with a notable blood glucose of 20 mg/dL...

The stress response to acute disease is characterized by activation of the hypothalamic-pituitary-adrenal (HPA) axis and the sympathoadrenal system, increased serum cortisol levels, increased percentage of its free fraction and increased nuclear translocation of the glucocorticoid-receptor complex, even though many pathways may be inhibited by poorly understood mechanisms. There is no consensus about the cutoff point of serum cortisol levels for defining adrenal insufficiency. Furthermore, recent data point to the participation of tissue resistance to glucocorticoids in acute systemic inflammatory processes...

PURPOSE: Etomidate causes adrenal insufficiency. Yet in critically ill patients, it is controversial whether it increases mortality rates above that of comparator anesthetic induction agents. We postulated that etomidate would increase relative mortality rates correspondingly to the severity of illness as defined by SAPS or APACHE scores. MATERIALS AND METHODS: A literature search was performed on Pub Med, SCOPUS, and Cochrane Reviews for human studies, regardless of language, between 1983 and February 2020...

BACKGROUND: Although the measuring free cortisol is ideal for assessment of hypothalamicpituitary-adrenal function, it is not routinely measured. Salivary cortisol correlates well with the biologically active free cortisol. Therefore, this study measured the morning basal as well as adrenocorticotropic hormone-stimulated salivary cortisol levels in mechanically ventilated patients and compared the results with non-critically ill patients. METHODS: We prospectively enrolled 49 mechanically ventilated patients and 120 patients from the outpatient clinic...

PURPOSE: Glucocorticoids (GCs), alone or associated to other drugs, were widely used in the management of patients affected by severe acute respiratory syndrome caused by SARS-CoV-2 infection, during the recent COVID-19 outbreak. This review summarizes the available data on HPA axis impairment in GC-treated SARS-CoV-2 patients, focusing on the risk of adrenal insufficiency and on potential drug interactions during concomitant treatments. METHODS: Literature on the impact of GCs therapy on HPA axis and on the consequences of coadministration of GCs and other drugs in SARS-CoV-2 patients has been reviewed...
