Abstract
Critical illness-related corticosteroid insufficiency or CIRCI is characterized by acute and life-threatening disfunction of hypothalamic-pituitary-adrenal (HPA) axis observed among intensive care unit- staying patients.It is associated with increased circulating levels of biological markers of inflammation and coagulation, morbidity, length of ICU stay, and mortality.Several mechanisms are involved in CIRCI pathogenesis: reduced CRH-stimulated ACTH release, peripheral resistance to glucocorticoids, altered cortisol synthesis, impaired cortisol-free fraction and bioavailability.Diagnostic and therapeutic management of this condition in children is still debated, probably because of the lack of agreement among intensive care specialists and endocrinologists regarding diagnostic criteria and prevalence of CIRCI in paediatric age.In the present narrative review, we focused on definition of CIRCI in paediatric age and we advise on how to diagnose and treat this poorly understood condition, based on current literature data.

Abstract
OBJECTIVES Corticosteroids are commonly used in the treatment of pediatric septic shock without clear evidence of the potential benefits or risks. This study examined the association of early corticosteroid therapy with patient-centered clinically meaningful outcomes. DESIGN Subsequent cohort analysis of data derived from the prospective Life After Pediatric Sepsis Evaluation (LAPSE) investigation. Outcomes among patients receiving hydrocortisone or methylprednisolone on study day 0 or 1 were compared with those who did not use a propensity score-weighted analysis that controlled for age, sex, study site, and measures of first-day illness severity. SETTING Twelve academic PICUs in the United States. PATIENTS Children with community-acquired septic shock 1 month to 18 years old enrolled in LAPSE, 2013-2017. Exclusion criteria included a history of chronic corticosteroid administration. INTERVENTIONS None. MEASUREMENTS AND MAIN RESULTS Among children enrolled in LAPSE, 352 of 392 met analysis inclusion criteria, and 155 of 352 (44%) received early corticosteroid therapy. After weighting corticosteroid therapy administration propensity across potentially confounding baseline characteristics, differences in outcomes associated with treatment were not statistically significant (adjusted effect or odds ratio [95% CI]): vasoactive-inotropic support duration (-0.37 d [-1.47 to 0.72]; p = 0.503), short-term survival without new morbidity (1.37 [0.83-2.28]; p = 0.218), new morbidity among month-1 survivors (0.70 [0.39-1.23]; p = 0.218), and persistent severe deterioration of health-related quality of life or mortality at month 1 (0.70 [0.40-1.23]; p = 0.212). CONCLUSIONS This study examined the association of early corticosteroid therapy with mortality and morbidity among children encountering septic shock. After adjusting for variables with the potential to confound the relationship between early corticosteroid administration and clinically meaningful end points, there was no improvement in outcomes associated with this therapy. Results from this propensity analysis provide additional justification for equipoise regarding corticosteroid therapy for pediatric septic shock and ascertain the need for a well-designed clinical trial to examine benefit/risk for this intervention.

Abstract
Neonatal encephalopathy due to a hypoxic-ischemic event is commonly associated with cardiac dysfunction and acute pulmonary hypertension; both therapeutic hypothermia and rewarming modify loading conditions and blood flow. The pathophysiological contributors to disease are complex with a high degree of clinical overlap and traditional bedside measures used to assess circulatory adequacy have multiple confounders. Comprehensive, quantitative echocardiography may be used to delineate the relative contribution of lung parenchymal, pulmonary vascular, and cardiac disease to hypotension and/or hypoxemic respiratory failure. In this review, we provide a detailed overview of the contributors to hemodynamic instability following perinatal hypoxic-ischemic injury. Our proposed approach to therapy focuses on physiopathological considerations with interventions individualized to this potentially complex condition and considers the pharmacological idiosyncrasies, which may occur among neonates with NE presenting with multiorgan dysfunction while undergoing therapeutic hypothermia.

Abstract
BACKGROUND Inflammatory mediators released during septic shock are involved in the mechanism of adrenal insufficiency. This study investigated the role of interleukin (IL)-6, IL-1, tumor necrosis factor (TNF)-α, and macrophage migration inhibitory factor (MIF) in septic shock with relative adrenal insufficiency (RAI).
METHODS We conducted a 6-month experimental study in 20 piglets. Following endotoxin administration, their hemodynamics were monitored and blood samples were drawn to test the levels of cytokines IL-1, IL-6, TNF-α, and MIF every 15 min until septic shock onset as well as during a corticotropin stimulation test. Septic shock was managed by administering fluid resuscitation, inotropic drugs, and hydrocortisone. At the end of the study, the piglet models were classified as either RAI or non-RAI. Immunohistochemistry staining was performed on the hypothalamus of the RAI group.
RESULTS The level of IL-6 at 45 min was higher in the RAI group than the non-RAI group (p = 0.008), and that of IL-1 was similar in the two groups during septic shock. The RAI group had higher TNF-α levels at 15 min (p = 0.002) and at 30 min (p = 0.007) than the non-RAI group, and the MIF level during septic shock was higher in the RAI group (p = 0.003) than the non-RAI group.
CONCLUSIONS Cytokine-induced inflammatory process of adrenal gland reflected in TNF-α level in 15 min and 30 min, IL-6 in 45 min, and MIF in septic shock condition but not in IL-1.

Abstract
PURPOSE The purpose of this review article is to discuss considerations for the critically ill child presenting to an emergency department (ED) with pharmacists who have minimal to no pediatric training. SUMMARY In 2015, 17% of all children visited an ED, constituting 30 million visits. The majority of these children were treated at community hospitals where pediatric care resources, including a pediatric-trained pharmacist, may be limited. Because of the complex array of ages and disease states, the care of critically ill children in the ED creates many concerns for adult and community hospitals. This article will focus on several common disease states seen in the pediatric ED, including septic shock, trauma, status epilepticus, and diabetic ketoacidosis. CONCLUSION Critically ill children admitted to a community or adult ED provide therapeutic dilemmas and medication safety concerns. A pharmacist with training or experience in pediatrics can have a major impact in patient outcomes in many of the disease states seen in these pediatric patients. This article highlights several key differences between critically ill pediatric and adult patients to better prepare all pharmacists to care for these vulnerable patients.

Abstract
OBJECTIVE To investigate whether hydrocortisone supplementation increases blood pressure and decreases inotrope requirements compared with placebo in cooled, asphyxiated neonates with volume-resistant hypotension. STUDY DESIGN A double-blind, randomized, placebo-controlled clinical trial was conducted in a Level III neonatal intensive care unit in 2016-2017. Thirty-five asphyxiated neonates with volume-resistant hypotension (defined as a mean arterial pressure [MAP] < gestational age in weeks) were randomly assigned to receive 0.5 mg/kg/6 hours of hydrocortisone or placebo in addition to standard dopamine treatment during hypothermia. RESULTS More patients reached the target of at least 5-mm Hg increment of MAP in 2 hours after randomization in the hydrocortisone group, compared with the placebo group (94% vs 58%, P = .02, intention-to-treat analysis). The duration of cardiovascular support (P = .001) as well as cumulative (P < .001) and peak inotrope dosage (P < .001) were lower in the hydrocortisone group. In a per-protocol analysis, regression modeling predicted that a 4-mm Hg increase in MAP in response to hydrocortisone treatment was comparable with the effect of 15 μg/kg/min of dopamine in this patient population. Serum cortisol concentrations were low before randomization in both the hydrocortisone and placebo groups (median 3.5 and 3.3 μg/dL, P = .87; respectively), suggesting inappropriate adrenal function. Short-term clinical outcomes were similar in the 2 groups. CONCLUSIONS Hydrocortisone administration was effective in raising the blood pressure and decreasing inotrope requirement in asphyxiated neonates with volume-resistant hypotension during hypothermia treatment.

Abstract
Background Relative adrenal insufficiency (RAI) is the inadequate production of cortisol due to dysfunction of the hypothalamic-pituitary-adrenal (HPA) axis during a severe illness. We evaluated the HPA axis and RAI in a tertiary pediatric intensive care unit (PICU). Methods A total of 100 PICU patients were included in this prospective cohort study. Basal serum levels of adrenocorticotropic hormone (ACTH), cortisol values were compared with those in the control group. A low-dose ACTH stimulation test was performed in patients with basal cortisol levels below 18 µg/dL. Results The basal cortisol levels of the PICU patients were significantly higher than those of the control group (P < 0.05). All tested patients (n= 24) had delta cortisol levels > 9 µg/dL and a peak cortisol response > 18 µg/dL. Basal cortisol levels were positively correlated with Pediatric Risk of Mortality (PRISM) III scores (P < 0.05; r = 0.363). The basal or stimulated cortisol levels of the patients who received glucocorticoid treatment were higher than the cut-off levels. Conclusions High basal or stimulated cortisol levels are indicative of disease severity in the acute phase of stress. Patients with very high cortisol levels should be particularly carefully monitored because of the high mortality risk.

SAGE Open Med 2018; 6:2050312118802452.

Abstract
OBJECTIVE Measurement of salivary biomarkers can provide important information regarding hypothalamic-pituitary-adrenal axis activity both under normal conditions as well as in response to psychological or physical stress. Our aim was to correlate salivary stress markers, such as cortisol, α-amylase and immunoglobulin A, with the Pediatric Risk Index Score of Mortality, underlying disease (pathologic, trauma and postoperative), need for mechanical ventilation/sedation and time lag between onset of illness and admission in children admitted in the pediatric intensive care unit. METHODS We enrolled 79 pediatric intensive care unit patients (2-14 years) over a 2-year period, which satisfy the including criteria, but finally salivary biomarkers were evaluated in 65 patients. Saliva samples were collected within 24 h of admission at 8 a.m., 2 p.m. and 8 p.m. to examine potential disruption of circadian rhythm. RESULTS Overall, the salivary biomarkers were increased; specifically, median values were (a) cortisol at 8 a.m.: 50.04 nmol/L, 2 p.m.: 30.69 nmol/L and 8 p.m.: 247.12 nmol/L; (b) α-amylase: at 8 a.m.: 22.567 U/L; 2 p.m.: 22.702 U/L and 8 p.m.: 21.484 U/L and (c) IgA at 8 a.m.: 95.10 mg/dL, 2 p.m.: 88.55 mg/dL and 8 p.m.: 80.80 mg/dL. Significantly higher levels were demonstrated in children younger than 6 years and those with Pediatric Risk Index Score of Mortality ⩾8 upon admission. Disturbances in circadian rhythm were observed. Cortisol circadian rhythm disturbance was observed only in children with Pediatric Risk Index Score of Mortality score ⩾8 upon admission while maintaining normal α-amylase circadian rhythm, which was associated with less than 3 days hospitalization in pediatric intensive care unit. No daily variance in IgA was observed. CONCLUSION Salivary biomarkers may serve, in critically ill children, as a sensitive, non-invasive method, important for the early recognition of those at high risk and guiding intervention, before clinical deterioration, promoting the quality of health care in pediatric population.

Abstract
OBJECTIVE The definition of an adequate adrenal response in critically ill children continues to be controversial. We aimed to evaluate the cortisol levels at baseline and after adrenocorticotropin (ACTH) stimulation and determine their association to clinical outcome of critically ill children. METHODS All children who underwent an ACTH test in the pediatric intensive care unit (PICU) in a tertiary medical center between 2006 and 2013 were included in the study. Data on age, sex, diagnosis, vasoactive-inotropic score, length of pediatric intensive care unit stay, and mortality were obtained. Laboratory variables included hematologic and chemistry data, arterial lactate, and total plasma cortisol levels at baseline and after ACTH stimulation. RESULTS Ninety-nine patients (61 males; median [range] age, 2 [0-204] months) were enrolled. The mortality rate of children with a baseline cortisol level of 600 nmol/L or greater was 36% (12/33 patients) versus 18% (12/66 patients) for children with a baseline cortisol level of less than 600 nmol/L (odds ratio, 2.6 [95% confidence interval, 1-6.6]; P = 0.05). There was a positive correlation between baseline cortisol and lactate levels (r = 0.40, P < 0.0001), vasoactive-inotropic scores (r = 0.24, P = 0.02), and mortality (P = 0.05). There was no correlation between peak cortisol measured at the ACTH test or the delta increment of cortisol from baseline and mortality. CONCLUSIONS A high baseline cortisol level in critically ill children was associated with more severe illness, higher lactate level, and a higher mortality rate. Routine baseline cortisol assessment is recommended to identify patients at high mortality risk.

Abstract
Septic shock remains the major cause of childhood morbidity and mortality worldwide. Although early sepsis recognition, fluid resuscitation, timely administration of antimicrobials, and vasoactive-inotropic drug infusions are all key to achieving good sepsis outcomes, therapy using various steroid drug classes remains an attractive adjunctive intervention to minimize the duration of septic shock and transition to multiple organ dysfunction syndrome. All steroid drug classes possess biological plausibility to affect a beneficial clinical effect among children with septic shock, but none has undergone rigorous, prospective assessment in a large, high-quality pediatric interventional trial.

Abstract
OBJECTIVES The 2012 Surviving Sepsis Campaign pediatric guidelines recommend stress dose hydrocortisone in children experiencing catecholamine-dependent septic shock with suspected or proven absolute adrenal insufficiency. We evaluated whether stress dose hydrocortisone therapy in children with catecholamine dependent septic shock correlated with random serum total cortisol levels and was associated with improved outcomes. DESIGN Retrospective cohort study. SETTING Non-cardiac PICU. PATIENTS Critically ill children (1 mo to 18 yr) admitted between January 1, 2013, and December 31, 2013, with catecholamine dependent septic shock who had random serum total cortisol levels measured prior to potential stress dose hydrocortisone therapy. INTERVENTIONS None. MEASUREMENTS AND MAIN RESULTS The cohort was dichotomized to random serum total cortisol less than 18 mcg/dL and greater than or equal to 18 mcg/dL. Associations of stress dose hydrocortisone with outcomes: PICU mortality, PICU and hospital length of stay, ventilator-free days, and vasopressor-free days were examined. Seventy children with catecholamine-dependent septic shock and measured random serum total cortisol levels were eligible (16% PICU mortality). Although 43% (30/70) had random serum total cortisol less than 18 μg/dL, 60% (42/70) received stress dose hydrocortisone. Children with random serum total cortisol less than 18 μg/dL had lower severity of illness and lower Vasopressor Inotrope Scores than those with random serum total cortisol greater than or equal to 18 μg/dL (all p < 0.05). Children with stress dose hydrocortisone had higher severity of illness and PICU mortality than those without stress dose hydrocortisone (all p < 0.05). Mean random serum total cortisol levels were similar in children with and without stress dose hydrocortisone (21.1 vs 18.7 μg/dL; p = 0.69). In children with random serum total cortisol less than 18 μg/dL, stress dose hydrocortisone was associated with greater PICU and hospital length of stay and fewer ventilator-free days (all p < 0.05). In children with random serum total cortisol greater than 18 μg/dL, stress dose hydrocortisone was associated with greater PICU mortality and fewer ventilator-free days and vasopressor-free days (all p < 0.05). CONCLUSIONS Stress dose hydrocortisone therapy in children with catecholamine-dependent septic shock correlated more with severity of illness than random serum total cortisol levels and was associated with worse outcomes, irrespective of random serum total cortisol levels.

[PMID: 27269194 DOI: 10.1016/j.ijpharm.2016.05.069] [Citation(s) in RCA: 12] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/04/2016] [Revised: 05/25/2016] [Accepted: 05/29/2016] [Indexed: 01/12/2023]
Abstract
A novel dual pH/redox-responsive polymeric nanoliposome system (NLs) loaded with a copper-liganded bioactive complex was prepared and designed as a controlled delivery system for the management of inflammation. The NLs were synthesised after preparation of the copper-glyglycine-prednisolone succinate] ([(Cu(glygly)(PS)]) complex, and the dual pH/redox responsive biopolymer respectively. The methodology undertaken for the development of the drug delivery system involved coordination of the bioactive to Copper (II), preparation of dual pH/redox responsive biopolymer, and the synthesis of dual pH/redox nanoliposomes. Characterisations of the prepared copper-liganded bioactive [Copper-glyglycine-prednisolone succinate] ([(Cu(glygly)(PS)]) complex, dual pH/redox responsive biopolymer (Eudragit E100-cystamine) and [(Cu(glygly)(PS)]-loaded NLs were carried out using spectroscopic and physicochemical techniques. Results indicated a high inflammatory/oxidant inhibitory activity of [Cu(glygly)(PS)] in comparison to the free PS drug. The [Cu(glygly)(PS)] complex exhibited a significant free radical-scavenging activity (60.1±1.2%) and lipoxygenase (LOX-5) inhibitory activity (36.6±1.3%) in comparison to PS which resulted in activity of 4.4±1.4% and inhibition of 6.1±2.6% respectively. The [Cu(glygly)(PS)] loaded NLs demonstrated low release profiles of 22.9±5.4% in 6h at pH 7.4, in comparison to a significant accelerated release at pH 5 in a reducing environment of 75.9±3.7% over 6h duration. Results suggest that the novel copper-liganded bioactive delivery system with controlled drug release mechanism could serve as a potential drug delivery system candidate in the management of inflammation.

Pediatric Cardiac Intensive Care Society 2014 Consensus Statement: Pharmacotherapies in Cardiac Critical Care Hormone Replacement Therapy. Pediatr Crit Care Med 2016; 17:S59-68.

Abstract
OBJECTIVE To provide an overview of the current literature on the use of hormone replacement therapies in pediatric cardiac critical care. DATA SOURCES PubMed, EMBASE, and the Cochrane Library were searched using keywords relevant to the hormonal therapy, with no limits on language but restricting the search to children 0-18 years old. STUDY SELECTION All clinical studies believed to have relevance were considered. Where studies in children were sparse, additional evidence was sought from adult studies. DATA EXTRACTION All relevant studies were reviewed, and the most relevant data were incorporated in this review. DATA SYNTHESIS All authors of this review contributed to the appraisal of the data extracted. Challenges and revisions by the authors were conducted by group e-mail debate. CONCLUSIONS Glycemic control: although it is likely that some children could benefit, the routine use of tight glycemic control cannot be recommended in children after cardiac surgery. Thyroid hormone replacement: routine use of thyroid hormone replacement to normalize levels after cardiac surgery cannot be recommended on current evidence. Until further evidence from adequately powered studies is available, therapeutic decisions should be based on individual patient circumstances. Corticosteroids: 1) cardiopulmonary bypass: although studies seem to favor steroid administration during surgery with cardiopulmonary bypass, a large randomized controlled trial is required before strong recommendations can be made; 2) refractory hypotension: the evidence for the use of steroid replacement in refractory hypotension is poor, and no firm recommendations can be made; and 3) abnormal adrenal function after cardiac surgery: there is inadequate evidence on which to make recommendations on the use of corticosteroid replacement in children with critical illness-related corticosteroid insufficiency in children following cardiac surgery.

Abstract
AIM Neonatal therapy-resistant septic shock is a common problem in middle and low-income countries. We investigated whether newborn infants with infection and therapy-resistant hypotension showed evidence of abnormal levels of cortisol or cortisol precursors. METHODS A total of 60 term or near term neonates with evidence of infection were enrolled after informed consent. Of these, 30 had an infection and refractory shock and 30 had an infection without shock. There were no detectable differences between the groups in the length of gestation, birth weight or gender distribution. Serum was obtained during days four and 14 after birth. Cortisol and cortisol precursor concentrations were analysed using liquid chromatography-tandem mass spectrometry. RESULTS The cortisol concentrations were low considering the expected responses to stress and they did not differ between the groups. The infants with infection and shock had higher serum dehydroepiandrosterone (DHEA) levels than those without shock (319.0 ± 110.3 μg/dL, versus 22.3 ± 18.3 μg/dL; p < 0.0001) and they also had higher 17-hydroxy-pregnenolone, pregnenolone and progesterone concentrations. There were no detectable differences in the levels of 17-hydroxy-progesterone, 11-deoxy-cortisol, cortisol or cortisone. CONCLUSION Septic newborn infants with therapy-resistant hypotension had very high DHEA levels, suggesting that 3-beta-hydroxysteroid dehydrogenase activity limited the rate of cortisol synthesis.

Abstract
OBJECTIVE Although corticosteroid (CS) supplementation for pediatric septic shock (PSS) is recommended by American College of Critical Care Medicine sepsis guidelines, most data are based on adult trials. Standardized protocols for stimulation testing for adrenal insufficiency (AI) and CS treatment in children have been reported, but the current state of CS use and protocols have not been evaluated in pediatric intensive care units in the United States. We surveyed a group of pediatric intensivists to assess current approaches. DESIGN An electronic survey with 54 questions on attitudes and current use of CSs was distributed to 49 pediatric critical care and 49 pediatric endocrinology fellowship program directors. MAIN RESULTS Twenty-one (43%) of 49 critical care recipients completed the survey. Eleven (52%) were from medical/surgical units and 10 (48%) were from medical/surgical/cardiac units, with a median of 24 beds and 1614 annual admissions. Thirteen (62%) of 21 recipients rated the importance of steroids in the management of PSS as greater than 4 or 5, with 1 being of no importance and 5 of critical importance. Nineteen (90%) of 21 recipients thought AI occurs "sometimes" or "often" in septic shock. Adrenocorticotropin stimulation testing was frequently used (19 of 21; 90%) but not in protocol. Eighteen (85%) of 21 recipients agreed that "some should" receive "steroids as it improves outcome" and 9% agreed that "most should…" Fourteen (66%) of 21 recipients reported that more than 50% of patients with vasopressor-refractory PSS receive CSs. Hydrocortisone was used in 21 (100%) of 21 recipients, but dosing and duration were variable. Concerns to limit/avoid CSs included hyperglycemia (38%), superinfections (81%), and critical illness myopathy (57%). Only 3 (14%) of 21 recipients reported that they used a CS protocol for PSS. Sixteen (76%) of 21 recipients were not comfortable drawing conclusions from adult studies for PSS. Nineteen (90%) of 21 recipients agreed that it would be important to perform a randomized trial for CS use in PSS. CONCLUSIONS Corticosteroids are used at most centers for treatment of PSS, but significant variation in attitudes and use exists. Most centers identify AI as frequent; most report variable use of stimulation testing and dosing of CSs. Few centers currently use a standard protocol for diagnosis and treatment. Interest in performing a randomized trial for CSs remains because in part of reluctance to accept adult trial data.

Abstract
Essential therapeutic principles in children with septic shock persist over time, although some new concepts have been recently incorporated, and fully awareness of pediatricians and intensivists is essential. Fluid resuscitation is a fundamental intervention, but the kind of ideal fluid has not been established yet, as each of these interventions has specific limitations and there is no evidence supportive of the superiority of one type of fluid. Should septic shock persists despite adequate fluid resuscitation, the use of inotropic medication and/or vasopressors is indicated. New vasoactive drugs can be used in refractory septic shock caused by vasopressors, and the use of hydrocortisone should be considered in children with suspected adrenal insufficiency, as it reduces the need for vasopressors. The indications for red blood cells transfusion or the optimal level of glycemia are still controversial, with no consensus on the threshold value for the use of these blood products or the initiation of insulin administration, respectively. Likewise, the use of high-volume hemofiltration is a controversial issue and further study is needed on the routine recommendation in the course of septic shock. Nutritional support is crucial, as malnutrition is a serious complication that should be properly prevented and treated. The aim of this paper is to provide update on the most recent advances as concerns the treatment of septic shock in the pediatric population.

Abstract
Adrenal reserve depletion and overstimulation of the hypothalamus-pituitary-adrenal (HPA) axis are causes for adrenal insufficiency (AI) in critically ill individuals. Cirrhosis is a predisposing condition for AI in cirrhotics as well. Both stable cirrhotics and liver transplant patients (early and later after transplantation) have been reported to present AI. The mechanisms leading to reduced cortisol production in cirrhotics are the combination of low cholesterol levels (the primary source of cortisol), the increased cytokines production that overstimulate and exhaust HPA axis and the destruction of adrenal glands due to coagulopathy. AI has been recorded in 10%-82% cirrhotics depending on the test used to evaluate adrenal function and in 9%-83% stable cirrhotics. The similarity of those proportions support the assumption that AI is an endogenous characteristic of liver disease. However, the lack of a gold standard method for AI assessment and the limitation of precise thresholds in cirrhotics make difficult the recording of the real prevalence of AI. This review aims to summarize the present data over AI in stable, critically ill cirrhotics and liver transplant recipients. Moreover, it provides information about the current knowledge in the used diagnostic tools and the possible effectiveness of corticosteroids administration in critically ill cirrhotics with AI.

Abstract
The nervous system and the endocrine system are closely interrelated and both involved intimately in maintaining homeostasis. Endocrine dysfunctions may lead to various neurologic manifestations such as headache, myopathy, and acute encephalopathy including coma. It is important to recognize the neurologic signs and symptoms caused by the endocrine disorders while managing endocrine disorders. This article provides an overview of the neurologic manifestations found in various endocrine disorders that affect pediatric patients. It is valuable to think about 'endocrine disorder' as a cause of the neurologic manifestations. Early diagnosis and treatment of hormonal imbalance can rapidly relieve the neurologic symptoms. Better understanding of the interaction between the endocrine system and the nervous system, combined with the knowledge about the pathophysiology of the neurologic manifestations presented in the endocrine disorders might allow earlier diagnosis and better treatment of the endocrine disorders.

Abstract
OBJECTIVE There is no consensus on adequate adrenal response to critical illness. We aimed to evaluate adrenal function in critically ill children and its association with clinical outcome. We hypothesized that salivary cortisol would be a more appropriate tool to evaluate adrenal function in critically ill children. METHODS This was a prospective cohort study. The concentrations of serum total and salivary cortisol were measured in 34 critically ill children before and after stimulation with 250 μg adrenocorticotropic hormone (ACTH), and values were compared to a control group of healthy children (n = 15). Association between outcome and adrenal insufficiency defined by an increment in serum cortisol ≤250 nm (9 μg/dl) post-ACTH was assessed. RESULTS Serum total and salivary cortisol concentrations pre- and post-ACTH were significantly higher in patients, and they were correlated at baseline (r = 0·67; P < 0·0001) and after ACTH (r = 0·41; P = 0·02). The incidence of adrenal insufficiency was 32·3%. This group had higher Paediatric Risk of Mortality III score (P = 0·04) but Paediatric Logistic Organ Dysfunction and vasoactive inotropic scores, duration of mechanical ventilation and length of paediatric intensive care unit and hospital stay were not significantly different compared with those with an increment >250 nm (9 μg/dl) post-ACTH. An inverse correlation between salivary cortisol post-ACTH and vasoactive inotropic score (r = -0·56; P = 0·0008) was observed. A salivary cortisol concentration post-ACTH of ≤226 nm (8·2 μg/dl) had a sensitivity of 79% and a specificity of 62% to discriminate need for vasoactive or inotropic support (area under receiver operating characteristic (ROC) curve 0·74). CONCLUSION Adrenal insufficiency defined by the 'delta criterion' was not associated with outcome. A post-ACTH salivary cortisol of ≤226 nm (8·2 μg/dl) may be suggestive of an insufficient adrenal response to critical illness.

Abstract
Sepsis, a common and potentially fatal systemic illness, is triggered by microbial infection and often leads to impaired function of the lungs, kidneys or other vital organs. Since the early 1980s, a large number of therapeutic agents for the treatment of sepsis have been evaluated in randomized controlled clinical trials. With few exceptions, the results from these trials have been disappointing, and no specific therapeutic agent is currently approved for the treatment of sepsis. To improve upon this dismal record, investigators will need to identify more suitable therapeutic targets, improve their approaches for selecting candidate compounds for clinical development and adopt better designs for clinical trials.

Abstract
Although some evidence suggests benefit of steroid supplementation after pediatric cardiac surgery, data correlating adrenal function with the postoperative course is scarce. This study sought to determine if adrenal insufficiency (AI) after cardiac surgery is associated with a more complicated postoperative course in children. A prospective study was performed during a 6-month period at a pediatric medical center. Included were 119 children, 3 months and older, who underwent heart surgery with cardiopulmonary bypass. Cortisol levels were measured before and 18 h after surgery. Patients were divided into two groups by procedure complexity (low or high), and clinical and laboratory parameters were compared between patients with and without AI within each complexity group. In the low-complexity group, 45 of the 65 patients had AI. The normal adrenal function (NAF) subgroup had greater inotropic support at 12, 24, and 36 h after surgery and a higher lactate level at 12 and 24 h after surgery. There were no significant differences between subgroups in duration of ventilation, sedation, intensive care unit (ICU) stay, or urine output. In the high-complexity group, 27 patients had AI, and 27 did not. There were no significant differences between subgroups in inotropic support or urine output during the first 36 h or in mechanical ventilation, sedation, or ICU stay duration. Children with AI after heart surgery do not have a more complex postoperative course than children with NAF. The adrenal response of individual patients seems to be appropriate for their cardiovascular status.

Abstract
Adequate adrenocortical function is essential for survival in critical illness. Most critically ill patients display elevated plasma cortisol concentrations, which reflects activation of the hypothalamic-pituitary-adrenal axis and is considered to be a homeostatic adaptation. However, many critically ill patients have 'relative' or 'functional' adrenal insufficiency, which is characterized by an inadequate production of cortisol in relation to an increased demand during periods of severe stress. Recently, the term 'critical illness-related corticosteroid insufficiency' (CIRCI) was coined. CIRCI occurs as a result of a decrease in adrenal steroid production or tissue resistance to glucocorticoids. An international task force of the American College of Critical Care Medicine issued recommendations for the diagnosis and management of this condition in adult patients. We review the prevalence, diagnosis, and therapeutic approach to adrenal insufficiency in critically ill children. We found a lack of consensus within the pediatric field as to the optimal approach to CIRCI, and call for an international task force to establish unified guidelines.

Abstract
BACKGROUND To study hormonal changes associated with severe hyperglycemia in critically ill children and the relationship with prognosis and length of stay in intensive care. METHODS Observational study in twenty-nine critically ill children with severe hyperglycemia defined as 2 blood glucose measurements greater than 180 mg/dL. Severity of illness was assessed using pediatric index of mortality (PIM2), pediatric risk of mortality (PRISM) score, and pediatric logistic organ dysfunction (PELOD) scales. Blood glucose, glycosuria, insulin, C-peptide, cortisol, corticotropin, insulinlike growth factor-1, growth hormone, thyrotropin, thyroxine, and treatment with insulin were recorded. β-cell function and insulin sensitivity and resistance were determined on the basis of the homeostatic model assessment (HOMA), using blood glucose and C-peptide levels. RESULTS The initial blood glucose level was 249 mg/dL and fell gradually to 125 mg/dL at 72 hours. Initial β-cell function (49.2%) and insulin sensitivity (13.2%) were low. At the time of diagnosis of hyperglycemia, 50% of the patients presented insulin resistance and β-cell dysfunction, 46% presented isolated insulin resistance, and 4% isolated β-cell dysfunction. β-cell function improved rapidly but insulin resistance persisted. Initial glycemia did not correlate with any other factor, and there was no relationship between glycemia and mortality. Patients who died had higher cortisol and growth hormone levels at diagnosis. Length of stay was correlated by univariate analysis, but not by multivariate analysis, with C-peptide and glycemic control at 24 hours, insulin resistance, and severity of illness scores. CONCLUSIONS Critically ill children with severe hyperglycemia initially present decreased β-cell function and insulin sensitivity. Nonsurvivors had higher cortisol and growth hormone levels and developed hyperglycemia later than survivors.

Abstract
During stress, the relationship between the central nervous system and the immune system is essential to maintain homeostasis. The main neuroendocrine system involved in this interaction is the hypothalamic-pituitary-adrenal axis (HPA), which via the synthesis of glucocorticoids will modulate the intensity of the inflammatory response. Anaesthetic agents could be interacting with the HPA axis during surgery. Although etomidate currently remains in the center of the discussions, it seems, at least experimentally, that most hypnotics have the capacity to modulate the synthesis of adrenal steroids. Nevertheless, with the large literature on this subject, etomidate seems to be the most deleterious hypnotic agent on the HPA axis function. Its use should be limited when HPA axis is already altered.

Abstract
BACKGROUND We sought to determine whether immediate postoperative serum cortisol concentration predicts adrenal insufficiency in neonates after cardiac surgery with cardiopulmonary bypass. We hypothesized that cortisol <10 µg/dL would be associated with increased catecholamine requirements and fluid resuscitation and would predict hemodynamic responsiveness to exogenous steroids. METHODS Retrospective study of 41 neonates was carried out for the levels of cortisol in the immediate postoperative period; of whom, 15 received steroids due to high levels of inotropic support. Laboratory and clinical outcomes were collected. RESULTS Median cortisol was 12 µg/dL (interquartile range: 5.2-27.4). Levels of cortisol <10 µg/dL was not associated with any clinical variable indicative of increased illness severity. Peak lactate (9.1 vs 11.8 mmol/L, P = .04) and maximum arteriovenous saturation difference ([Sao 2 - Svo 2] 28% vs 32%, P = .05) were both lower among patients with levels of cortisol <10 µg/dL. Six (40%) patients had a significant hemodynamic improvement within 24 hours after receiving steroids (responders), although there was no statistical difference between levels of cortisol in responders versus nonresponders. Level of cortisol was positively correlated with maximum lactate (P < .001), maximum Sao 2 - Svo 2 (P < .001), maximum inotrope score (P = .014), initial 24-hour fluid intake (P = .012), and time to negative fluid balance (P = .008) and was negatively correlated with initial 24-hour urine output (P < .001). CONCLUSIONS Low cortisol obtained in the immediate postoperative period is not associated with worse postoperative outcomes or predictive of steroid responsiveness. In contrast, elevated levels of cortisol are positively correlated with severity of illness. The use of an absolute cortisol threshold to identify adrenal insufficiency and/or guide steroid therapy in neonates after cardiac surgery is unjustified.

Abstract
BACKGROUND The renin-angiotensin-aldosterone system (RAAS) and hypothalamic-pituitary-adrenal axis (HPAA) and their interactions during illness and hypoperfusion are important to maintain organ function. HPAA dysfunction and relative adrenal insufficiency (RAI) are common in septic foals. Information is lacking on the RAAS and mineralocorticoid response in the context of RAI in newborn sick foals. OBJECTIVES/HYPOTHESIS To investigate the RAAS, as well as HPAA factors that interact with the RAAS, in hospitalized foals, and to determine their association with clinical findings. We hypothesized that critical illness in newborn foals results in RAAS activation, and that inappropriately low aldosterone concentrations are part of the RAI syndrome of critically ill foals. ANIMALS A total of 167 foals ≤3 days of age: 133 hospitalized (74 septic, 59 sick nonseptic) and 34 healthy foals. METHODS Prospective, multicenter, cross-sectional study. Blood samples were collected on admission. Plasma renin activity (PRA) and angiotensin-II (ANG-II), aldosterone, ACTH, and cortisol concentrations were measured in all foals. RESULTS ANG-II, aldosterone, ACTH, and cortisol concentrations as well as ACTH/aldosterone and ACTH/cortisol ratios were higher in septic foals compared with healthy foals (P < .05). No difference in PRA between groups was found. High serum potassium and low serum chloride concentrations were associated with hyperaldosteronemia in septic foals. CONCLUSIONS AND CLINICAL IMPORTANCE RAAS activation in critically ill foals is characterized by increased ANG-II and aldosterone concentrations. Inappropriately low cortisol and aldosterone concentrations defined as high ACTH/cortisol and ACTH/aldosterone ratios in septic foals suggest that RAI is not restricted to the zona fasciculata in critically ill newborn foals.

Abstract
Sepsis remains an important challenge in pediatric critical care medicine. This review provides an appraisal of adjunctive therapies for sepsis and highlights opportunities for meeting selected challenges in the field. Future clinical studies should address long-term and functional outcomes as well as acute outcomes. Potential adjunctive therapies such as corticosteroids, hemofiltration, hemoadsorption, and plasmapheresis may have important roles, but still require formal and more rigorous testing by way of clinical trials. Finally, the design of future clinical trials should consider novel approaches for stratifying outcome risks as a means of improving the risk-to-benefit ratio of experimental therapies.

Abstract
BACKGROUND Assessment and treatment of adrenal axis function in critically ill pediatric patients with oncologic disorders have not been well elucidated. Critically ill children with oncologic disorders may be at increased risk for adrenal insufficiency (AI). OBJECTIVE The aim of the present study was to evaluate the incidence of AI in a cohort of hypotensive patients with oncologic disorders and the correlation of AI with hemodynamic response to corticosteroids. DESIGN/METHODS This is a retrospective review of pediatric oncology patients with systemic inflammatory response syndrome and vasopressor-dependent shock receiving protocol-based adrenocorticotropin testing and steroid supplementation. Vasopressor dose requirements were evaluated before and after the initiation of corticosteroids. Absolute AI (AAI) was defined as baseline cortisol less than 18 μg/dL. Relative AI (RAI) was defined as δ-cortisol less than 9 μg/dL. RESULTS Twenty patients received adrenocorticotropin testing; primary diagnoses were 13 hematologic malignancies and 7 solid tumors. The median age was 132 months (range, 4-224 months). The median fluid resuscitation was 80 mL/kg (range, 60-120 mL/kg), with 10 (50%) of 20 patients requiring mechanical ventilation for a median of 12 days. Overall, 10 (50%) of 20 patients met the definition for RAI, 15 (75%) of 20 met the definition for AAI, and 18 (90%) of 20 had either AAI or RAI. All patients received steroids: 18 (90%) of 20 on dopamine and 17 (85%) of 20 on norepinephrine. After the introduction of steroids, dosage of norepinephrine and dopamine was significantly reduced in 4 hours (P = .0001). CONCLUSIONS Both RAI and AAI were common in this cohort of critically ill pediatric patients with oncologic disorders. Introduction of steroids was associated with a significant reduction in vasopressors dose.
