    Full Text Available Post-transplant lymphoproliferative disorder is treated with rapid decrement of immunosuppressive therapy. This cannot be achieved with ease in patients on long-term glucocorticoid therapy, as chronically suppressed adrenal glands may not be capable of mounting adequate response to stress. A 52-year-old Caucasian male presented with fever, orthostatic hypotension, lymphadenopathy and hyponatraemia. Serum cortisol levels were within normal levels with a sub optimal response to stimulation by ACTH. Hyponatraemia and orthostasis responded poorly to fluid restriction, saline and salt repletion but corrected after increasing the steroid dose. The normal baseline cortisol levels represented a stimulated adrenal gland, however, the ACTH stimulation had inadequate response. This sub optimal stimulation and a good response to increased steroids suggest the presence of relative or occult adrenal insufficiency. Relative adrenal insufficiency must be considered in patients who have received prolonged glucocorticoid therapy and have symptoms such as hypotension and/or hyponatraemia.

    Adrenal insufficiency, a rare disorder which is characterized by the inadequate production or absence of adrenal hormones, may be classified as primary adrenal insufficiency in case of direct affection of the adrenal glands or secondary adrenal insufficiency, which is mostly due to pituitary or hypothalamic disease. Primary adrenal insufficiency affects 11 of 100,000 individuals. Clinical symptoms are mainly nonspecific and include fatigue, weight loss, and hypotension. The diagnostic test of choice is dynamic testing with synthetic ACTH. Patients suffering from chronic adrenal insufficiency require lifelong hormone supplementation. Education in dose adaption during physical and mental stress or emergency situations is essential to prevent life-threatening adrenal crises. Patients with adrenal insufficiency should carry an emergency card and emergency kit with them.

    To assess the prevalence of relative adrenal insufficiency in patients successfully resuscitated after cardiac arrest, and its prognostic role in post-resuscitation disease. A prospective observational single-center study in a medical intensive care unit. 64 patients hospitalised in the intensive care unit after successful resuscitation for out-of-hospital cardiac arrest. A corticotropin-stimulation test was performed between 12 and 24 h following admission: serum cortisol level was measured before and 60 min after administration of tetracosactide 250 microg. Patients with an incremental response less than 9 microg/dl were considered to have relative adrenal insufficiency (non-responders). Variables were expressed as medians and interquartile ranges. 33 patients (52%) had relative adrenal insufficiency. Baseline cortisol level was higher in non-responders than in responders (41 [27.2-55.5] vs. 22.8 [15.7-35.1] microg/dl respectively, P=0.001). A long interval before initiation of cardiopulmonary resuscitation was associated with relative adrenal insufficiency (5 [3-10] vs. 3 [3-5] min, P=0.03). Of the 38 patients with post-resuscitation shock, 13 died of irreversible multiorgan failure. The presence of relative adrenal insufficiency was identified as a poor prognostic factor of shock-related mortality (log-rank P=0.02). A trend towards higher mortality in non-responders was identified in a multivariate logistic regression analysis (odds ratio 6.77, CI 95% 0.94-48.99, P=0.058). Relative adrenal insufficiency occurs frequently after successful resuscitation of out-of-hospital cardiac arrest, and appears to be associated with a poor prognosis in cases of post-resuscitation shock. The role of corticosteroid supplementation should be evaluated in this setting.

    2015-01-01

    Adrenal insufficiency (glucocorticoid deficiency) comprises a group of rare diseases, including primary adrenal insufficiency, secondary adrenal insufficiency and congenital adrenal hyperplasia. Lifesaving glucocorticoid therapy was introduced over 60 years ago, but since then a number of advances in treatment have taken place. Specifically, little is known about short- and long-term treatment effects, and morbidity and mortality. Over the past decade, systematic cohort and registry studies have described reduced health-related quality of life, an unfavourable metabolic profile and increased mortality in patients with adrenal insufficiency, which may relate to unphysiological glucocorticoid replacement. This has led to the development of new modes of replacement that aim to mimic normal glucocorticoid physiology. Here, evidence for the inadequacy of conventional glucocorticoid therapy and recent developments in treatment are reviewed, with an emphasis on primary adrenal insufficiency.

    Adrenal insufficiency is a rare but life-threatening disorder. Clinical manifestations include fatigue, weight loss, gastrointestinal manifestations and skin hyperpigmentation, the latter being specific of primary adrenal failure. Because of non-specific clinical features of this rare disorder, diagnosis can be delayed and adrenal failure be revealed by an acute crisis. Adrenal insufficiency can be primary (Addison disease), most frequently autoimmune, or secondary, resulting from long term administration of exogenous glucocorticoids or more rarely from pituitary disorders. Monitoring of substitutive treatment is now well codified. Patient education is very important in this chronic disease that remains associated with a persistent high risk of adrenal crisis.

  8. History of stress-related health changes: a cue to pursue a diagnosis of latent primary adrenal insufficiency.

    Routine delays in the diagnosis of primary adrenal insufficiency (PAI) are well known and conceivably attributable to the absence of cues, other than anti-adrenal autoantibodies, to pursue subclinical PAI. Subclinical PAI is latent unless the afflicted patient encounters stress such as an acute illness, surgery, psychosocial burden, etc. It remains to be demonstrated whether a history of stress-related health changes is a useful cue to pursue a diagnosis of latent PAI. The patients were selected for a history of recurrent symptoms, i.e., gastrointestinal symptoms, fatigue, or lassitude, aggravated by stress and alleviated by the removal of stress, and signs, i.e., weight loss, hypotension, and hyperpigmentation. As the early morning cortisol levels were low or low-normal and the adrenocorticotropic hormone (ACTH) levels were within the reference ranges, provocation tests, i.e., insulin-induced hypoglycemia tests and low-dose (1 μg) corticotropin tests (LDTs), were used to estimate the hypothalamus-pituitary-adrenal (HPA) axis status. Patients with the HPA axis dysfunction on two provocation tests were supplemented with physiologic doses of glucocorticoids (GCs). The effects of GC supplementation on stress-related health changes were observed. The ACTH levels after insulin-induced hypoglycemia were higher and the cortisol levels were lower in the patients than in the control subjects. The cortisol levels in the patients were increased less significantly by LDT than those observed in the control subjects. Stress-related health changes ceased to recur and signs, i.e., a low body weight, hypotension, and hyperpigmentation, were ameliorated following GC supplementation. A history of stress-related health changes is useful as a cue to pursue latent PAI in patients with low or low-normal early morning cortisol levels.

    Full Text Available Opioids have been the mainstay for pain relief and palliation over a long period of time. They are commonly abused by drug addicts and such dependence usually imparts severe physiologic effects on multiple organ systems. The negative impact of opioids on the endocrine system is poorly understood and often underestimated. We describe a patient who developed severe suppression of the hypothalamic-pituitary adrenal (HPA axis leading to secondary adrenal insufficiency due to long standing abuse of opioids.

    Williams syndrome is a developmental disorder including dysmorphia, cardiovascular malformations and a specific neuropsychological profile together with other associated disorders. We report the case of a 17-year old girl, born of a non-inbred marriage, with Williams syndrome discovered during an assessment of degree of failure to thrive. Its association with primary adrenal insufficiency makes it unique. Diagnosis is confirmed by cytogenetic and molecular analysis. Its management consists of the implementation of treatment for adrenal insufficiency associated with a clinico-biological monitoring.

    Background: Adrenal insufficiency (AI) is the most common endocrine complication among patients with AIDS/HIV infection and there are number of causes of AI in HIV patients. Human immunodeficiency virus directly as well as indirectly destroys adrenal glands. The estimates of its prevalence and severity vary. AI is the most life threatening but readily correctable endocrine complication that occurs in persons with HIV infection. This study was carried out to determine the frequency of Adrenal Insufficiency in HIV patients and their clinical features as proper diagnosis and timely treatment have been shown to improve quality of life and long-term mortality in AIDS patients. Methods: It was a cross sectional survey conducted at HIV clinic and Jinnah Allama Iqbal Institute of Diabetes and Endocrinology, Jinnah Hospital Lahore. Sixty-four HIV positive patients, both male and female, aged above 15 years were included in the study. HIV patients who had recently taken steroids, ketoconazole or rifampicin, determined on history, were excluded from the study. The data was collected on a structured proforma and analysis was performed in SPSS-21.0. Frequency and percentages for adrenal insufficiency and its characteristics were calculated. Chi-square test was used with p<0.05 as statistically significant. Results: In this study, 9 (14.06%) HIV patients were diagnosed with adrenal insufficiency, male to female ratio was 3.5:1 and AI was found statistically significantly associated with fatigue (p<0.008) and weight loss (p<0.001). Conclusion: Adrenal insufficiency was high among the patients with HIV, it was not gender specific but it was found to be associated with fatigue and weight loss. (author)

    Primary adrenal insufficiency (PAI) is characterized by impaired production of steroid hormones due to an adrenal cortex defect. This condition incurs a risk of acute insufficiency which may be life-threatening. Today, 80% of pediatric forms of PAI have a genetic origin but 5% have no clear genetic support. Recently discovered mutations in genes relating to oxidative stress have opened the way to research on genes unrelated to the adrenal gland. Identification of causal mutations in a gene responsible for PAI allows genetic counseling, guidance of follow-up and prevention of complications. This is particularly true for stress oxidative anomalies, as extra-adrenal manifestations may occur due to the sensitivity to oxidative stress of other organs such as the heart, thyroid, liver, kidney and pancreas.

    2015-09-01

    Full Text Available Primary adrenal insufficiency is defined by the impaired synthesis of adrenocortical hormones due to an intrinsic disease of the adrenal cortex. Determining its etiology is crucial to allow adequate long-term management and genetic counseling. We report the case of a male adolescent that presented in the neonatal period with adrenal crisis and received replacement therapy for primary adrenal insufficiency. During follow-up, adrenal hypoplasia congenita (AHC was suspected given his persistently raised adrenocorticotropic hormone levels, with markedly low 17-OH progesterone and androstenedione levels. DNA sequence analysis revealed a mutation in NR0B1 gene (c.1292delG, confirming the diagnosis. Delayed puberty and persistent low levels of gonadotropins led to testosterone replacement therapy. X-linked AHC is a rare cause of primary adrenal insufficiency and hypogonadotropic hypogonadism, related to mutations in NR0B1 gene. Despite its rarity, AHC should be considered in patients who present with primary adrenal failure, low levels of 17-OH progesterone and hypogonadotropic hypogonadism.

    The endocrine disorder adrenal insufficiency includes inadequate production of the steroid hormone cortisol. This results in poor physiological responses to illness, trauma or other stressors and risk of adrenal crisis. Management is based on administration of hydrocortisone. It is important to avoid under- or over-treatment and increase the dosage during times of physiological stress. To reduce morbidity, hospital admissions and mortality, the education and empowerment of parents and carers, and prompt intervention when necessary are essential. A steroid therapy card for adrenal insufficiency containing personal information on a patient\\'s condition was developed for use by families and their specialist centres.

    Full Text Available Bilateral adrenal hemorrhages rarely occur during the neonatal period and are often associated with traumatic vaginal deliveries. However, the adrenal gland has highly regenerative capabilities and adrenal insufficiency typically resolves over time. We evaluated a newborn female after experiencing fetal macrosomia and a traumatic vaginal delivery. She developed acidosis and acute renal injury. Large adrenal hemorrhages were noted bilaterally on ultrasound, and she was diagnosed with adrenal insufficiency based on characteristic electrolyte changes and a low cortisol (4.2 μg/dL. On follow-up testing, this patient was unable to be weaned off of hydrocortisone or fludrocortisone despite resolution of hemorrhages on ultrasound. Providers should consider bilateral adrenal hemorrhage when evaluating critically ill neonates after a traumatic delivery. In extreme cases, this may be a persistent process.

    Adrenal crisis (AC) is a life-threatening complication of adrenal insufficiency (AI), which according to retrospective data represents a significant clinical complication. Here we aimed to prospectively assess incidence of AC and mortality associated with AC in patients with chronic AI. A total of 423 patients with AI (primary AI, n = 221; secondary AI, n = 202) were prospectively followed up for 2 years. Baseline assessment included a general questionnaire and detailed written instructions on glucocorticoid dose adaptation during stress. Patients received follow-up questionnaires every 6 months and were contacted by phone in case of reported adrenal crisis. A total of 423 data sets were available for baseline analysis, and 364 patients (86%) completed the whole study. Sixy-four AC in 767.5 patient-years were documented (8.3 crises per 100 patient-years). Precipitating causes were mainly gastrointestinal infection, fever, and emotional stress (20%, respectively) but also other stressful events (eg, major pain, surgery, strenuous physical activity, heat, pregnancy) or unexplained sudden onset of AC (7%) were documented. Patients with a previous AC were at higher risk of crisis (odds ratio 2.85, 95% confidence interval 1.5-5.5, P cases death was associated with AC (0.5 AC related deaths per 100 patient-years). Even in educated patients with chronic adrenal insufficiency, AC occurs in a substantial proportion of cases. Furthermore, we identified AC-associated mortality in approximately 6% of AC. Our findings further emphasize the need for improved management of AC in patients with chronic AI.

    A 62-year-old Japanese man, a bronze medal winner in the World Championship of table tennis when in his 20s, was diagnosed with secondary adrenocortical insufficiency due to isolated adrenocorticotropic hormone (ACTH) deficiency, and steroid administration was started. About 1 year after the diagnosis, he took part in a table tennis championship which was open to those 40 years or older. He took 10 mg hydrocortisone after breakfast as usual, played 10 matches, each of which took 20–30 min, and won the championship in about 8 h. Since the man could not always win the gruelling competition even when in his 50s, it is suggested that extra steroid hormone is not necessary for patients with adrenocortical insufficiency due to ACTH deficiency in order to successfully engage in sports requiring such intensity and endurance.

    Successful treatment of Cushing syndrome causes transient or permanent adrenal insufficiency deriving from endogenous hypercortisolism-induced hypothalamus-pituitary-adrenal-axis suppression. We analyzed pre-treatment factors potentially affecting the duration of adrenal insufficiency. We conducted a retrospective analysis on patients successfully treated for Cushing disease (15 patients) who underwent transsphenoidal surgery, and nonmalignant primary adrenal Cushing syndrome (31 patients) who underwent unilateral adrenalectomy, divided into patients with overt primary adrenal Cushing syndrome (14 patients) and subclinical primary adrenal Cushing syndrome (17 patients). Epidemiological data, medical history, and hormonal parameters depending on the etiology of hypercortisolism were collected and compared to the duration of adrenal insufficiency. The median duration of follow-up after surgery for Cushing disease and primary adrenal Cushing syndrome was 70 and 48 months, respectively. In the Cushing disease group, the median duration of adrenal insufficiency after transsphenoidal surgery was 15 months: younger age at diagnosis and longer duration of signs and symptoms of hypercortisolism before diagnosis and surgery were associated with longer duration of adrenal insufficiency. The median duration of adrenal insufficiency was 6 months for subclinical primary adrenal Cushing syndrome and 18.5 months for overt primary adrenal Cushing syndrome. The biochemical severity of hypercortisolism, the grade of hypothalamus-pituitary-adrenal-axis suppression, and treatment with ketoconazole before surgery accounted for longer duration of adrenal insufficiency. In patients with Cushing disease, younger age and delayed diagnosis and treatment predict longer need for glucocorticoid replacement therapy after successful transsphenoidal surgery. In patients with primary adrenal Cushing syndrome, the severity of hypercortisolism plays a primary role in influencing the duration of

    To evaluate rectal hydrocortisone as an emergency glucocorticoid replacement therapy in adrenal insufficient children. A parental questionnaire evaluated preferred treatment, problems or benefits of i.m. and rectal hydrocortisone, frequency and indications for administration and who administered treatment. Admissions of children with adrenal insufficiency were monitored. There were 39/52 families who responded to the questionnaire. 93% (26/28) preferred rectal hydrocortisone. Parents or children who previously received emergency treatment from a doctor now self-administered rectal hydrocortisone. The cost of suppositories and i.m. hydrocortisone is similar; however, storage of suppositories was inconvenient. One girl presented with pneumonia and collapse despite rectal hydrocortisone and a hydrocortisone level at admission of >2000 nmol/l with normal electrolytes. Rectal hydrocortisone is an acceptable and safe emergency therapy. We still advise i.m. hydrocortisone if rectal administration is not possible or with suppository extrusion.

    Full Text Available Adrenal insufficiency is managed by hormone replacement therapy, which is far from optimal; the ability to generate functional steroidogenic cells would offer a unique opportunity for a curative approach to restoring the complex feedback regulation of the hypothalamic-pituitary-adrenal axis. Here, we generated human induced steroidogenic cells (hiSCs from fibroblasts, blood-, and urine-derived cells through forced expression of steroidogenic factor-1 and activation of the PKA and LHRH pathways. hiSCs had ultrastructural features resembling steroid-secreting cells, expressed steroidogenic enzymes, and secreted steroid hormones in response to stimuli. hiSCs were viable when transplanted into the mouse kidney capsule and intra-adrenal. Importantly, the hypocortisolism of hiSCs derived from patients with adrenal insufficiency due to congenital adrenal hyperplasia was rescued by expressing the wild-type version of the defective disease-causing enzymes. Our study provides an effective tool with many potential applications for studying adrenal pathobiology in a personalized manner and opens venues for the development of precision therapies.

    Full Text Available A 68 year-old Japanese man, who had been suffering from immobilization and disuse syndrome, was admitted to our hospital for evaluation of polyuria with polyposia, hyponatremia and low blood pressure. His plasma osmolality was greater than that of his urine. His endocrinological examination revealed low levels of plasma adrenocorticotropic hormone (ACTH and cortisol, and a normal response of ACTH to the corticotrophin-releasing hormone (CRH challenge. Plasma ACTH did not increase with insulin loading. A low plasma vasopressin (AVP level and no response of AVP to a 5% saline administration were observed. We diagnosed central adrenal insufficiency with central diabetes insipidus. Six months after starting administration of hydrocortisone and 1-deamino-8D-arginine vasopressin, his psychological symptoms had improved, and 1.5 years after starting treatment, he was able to walk. In conclusion, it is not particularly rare for adrenal insufficiency to be misdiagnosed as depression. However, a correct early diagnosis is necessary, because, if adrenal insufficiency is not definitively diagnosed, the patient's quality of life diminishes markedly.

    To describe the course of autoimmune hyperthyroid disease in a patient with corticotropin (ACTH) deficiency treated with glucocorticoids. We report the clinical presentation, laboratory data, imaging studies, and management of a patient with weight loss, fatigue, apathy, hallucinations, and arthritis. Autoimmune hyperthyroidism (positive thyroperoxidase and thyroglobulin antibodies and borderline positive thyrotropin receptor antibody) was diagnosed in a 71-year-old woman. New psychotic symptoms prompted brain magnetic resonance imaging, which revealed a partially empty sella. Undetectable morning cortisol, undetectable ACTH, and failure to stimulate cortisol with synthetic ACTH (cosyntropin 250 mcg) secured the diagnosis of long-standing secondary adrenal insufficiency. Hydrocortisone replacement improved the patient's symptoms, resolved the thyroid disease, and decreased thyroid antibody titers. In retrospect, the patient recalled severe postpartum hemorrhage requiring blood transfusion at age 38 years. A Sheehan event probably occurred 33 years before the patient presented with corticotropin deficiency. Hyperthyroidism accelerated cortisol metabolism and provoked symptoms of adrenal insufficiency. The hypocortisolemic state may precipitate hyperimmunity and autoimmune thyroid disease. Rapid resolution of hyperthyroidism and decreased thyroid antibody titers with glucocorticoid treatment support this hypothesis.

    Full Text Available The term adrenal insufficiency refers to the hypofunction of this gland. From the etiologic point of view it may be either primary or secondary. This insufficiency manifests as inadequate serum levels of cortisol and adrenal androgens in the secondary form and of these and mineralocorticoids in the primary one. Clinical manifestations are often nonspecific and, consequently, diagnosis may be difficult to establish and treatment may be delayed with increased morbidity and mortality. This article on adrenal insufficiency includes its definition, epidemiology, etiology, physiopathology, classification, clinical presentation, diagnostic criteria and treatment guidelines. Besides, some special situations like critically ill patients and pregnant women are given special consideration. Emphasis is done on a diagnostic algorithm to make it easier for general practitioners the approach to patients with this endocrine disorder. La insuficiencia adrenal (ia se refiere a la hipofunción de dicha glándula debida a causas tanto primarias como secundarias, que resultan en niveles plasmáticos inadecuados de cortisol, andrógenos adrenales y adicionalmente, en la falla primaria de mineralocorticoides. Sus manifestaciones inespecíficas dificultan o retrasan con frecuencia el diagnóstico y tratamiento oportuno, lo cual incrementa la morbilidad y eventualmente la mortalidad de estos pacientes. Se incluyen en este artículo: definición, epidemiología, causas, fisiopatología, clasificación, manifestaciones clínicas, diagnóstico y tratamiento de la IA. Además se consideran algunas situaciones especiales como la IA en el paciente críticamente enfermo y en la mujer gestante. Finalmente se hace especial énfasis en un algoritmo diagnóstico, con la finalidad de facilitarle al médico general un enfoque ágil y oportuno de los pacientes con este problema endocrino.

    The brain is a major target organ for cortisol considering its high density of glucocorticoid receptors. Several states of hypothalamus-pituitary-adrenal dysregulation point towards impairments in cognitive functioning. However, there is a very limited body of research on the effects of hypocortisolism on cognitive functioning. To evaluate cognitive functioning in patients with hypocortisolism (i.e., primary adrenal insufficiency (PAI)) and to examine the possible effect of postponing early-morning hydrocortisone intake on cognitive functioning. Thirty-one patients with PAI on regular morning hydrocortisone intake and 31 healthy matched controls underwent nine neuropsychological tests, evaluating memory and executive functioning. In addition, the effect of normal timing and postponement of morning hydrocortisone intake on neuropsychological tests were assessed in an additional 29 patients with PAI. Compared to controls, patients with PAI performed worse on auditory and visual memory tasks (all P ≤ 0.024) and executive functioning tasks (all P ≤ 0.012). In contrast, patients performed better on a concentration and an attention task (both Paffect the outcomes of neuropsychological tests. Patients on long-term hydrocortisone replacement for PAI show mild cognitive deficits compared to controls. There was no effect of postponement of regular hydrocortisone intake on cognition.

    Central diabetes insipidus (CDI) is an infrequent complication of neurosarcoidosis (NS). Its presentation may be masked by adrenal insufficiency (AI) and uncovered by subsequent steroid replacement. A 45-year-old woman with a history of NS presented 2 weeks after abrupt cessation of prednisone with nausea, vomiting, decreased oral intake and confusion. She was diagnosed with secondary AI and intravenous hydrocortisone was promptly begun. Over the next few days, however, the patient developed severe thirst and polyuria exceeding 6 L of urine per day, accompanied by hypernatraemia and hypo-osmolar urine. She was presumed to have CDI due to NS, and intranasal desmopressin was administered. This eventually normalised her urine output and serum sodium. The patient was discharged improved on intranasal desmopressin and oral prednisone. AI may mask the manifestation of CDI because low serum cortisol impairs renal-free water clearance. Steroid replacement reverses this process and unmasks an underlying CDI. 2015 BMJ Publishing Group Ltd.

    Patients with primary adrenal insufficiency (AI) need to replace glucocorticoids and mineralocorticoids that act on glucocorticoid (GR) and mineralocorticoid receptors (MR). Both receptors are highly expressed in the hippocampus and are closely associated with cognitive function, which might be impaired by insufficient or increased GR and MR stimulation. However, little is known about cognitive function in patients with AI. It was examined whether patients with AI exhibit worse cognitive function compared to sex-, age-, and education-matched controls. Cognitive function (executive function, concentration, verbal memory, visual memory, working memory, and autobiographical memory) was assessed in 30 patients with AI (mean age 52.4 yrs. ±14.4, n=21 women, mean duration of illness 18.2 yrs. ±11.1) and 30 matched controls. We also measured depressive symptoms, body mass index (BMI), and blood pressure. Patients with AI showed more depressive symptoms, had a greater BMI and lower systolic blood pressure compared to controls. Adjusted analyses controlling for these variables revealed that patients with AI performed significantly worse in verbal learning (F=7.8, p=.007). Executive function, concentration, working memory, verbal memory, visuospatial memory, and autobiographical memory did not differ between groups. No clinically relevant cognitive impairment was found in patients with AI compared to matched controls. Even long-term glucocorticoid and mineralocorticoid substitution over almost two decades appears to have only subtle effects on cognition in patients with AI. Copyright © 2015 Elsevier Ltd.

    The hypothalamic-pituitary-adrenal (HPA) axis is a classic neuroendocrine system. One of the best ways to understand the HPA axis is to appreciate its dynamics in the variety of diseases and syndromes that affect it. Excess glucocorticoid activity can be due to endogenous cortisol overproduction (spontaneous Cushing’s syndrome) or exogenous glucocorticoid therapy (iatrogenic Cushing’s syndrome). Endogenous Cushing’s syndrome can be subdivided into ACTH-dependent and ACTH-independent, the latter of which is usually due to autonomous adrenal overproduction. The former can be due to a pituitary corticotroph tumor (usually benign) or ectopic ACTH production from tumors outside the pituitary; both of these tumor types overexpress the proopiomelanocortin gene. The converse of Cushing’s syndrome is the lack of normal cortisol secretion and is usually due to adrenal destruction (primary adrenal insufficiency) or hypopituitarism (secondary adrenal insufficiency). Secondary adrenal insufficiency can also result from a rapid discontinuation of long-term, pharmacological glucocorticoid therapy because of HPA axis suppression and adrenal atrophy. Finally, mutations in the steroidogenic enzymes of the adrenal cortex can lead to congenital adrenal hyperplasia and an increase in precursor steroids, particularly androgens. When present in utero, this can lead to masculinization of a female fetus. An understanding of the dynamics of the HPA axis is necessary to master the diagnosis and differential diagnosis of pituitary-adrenal diseases. Furthermore, understanding the pathophysiology of the HPA axis gives great insight into its normal control. PMID:24715566

    2015-01-01

    Case-reports have made it evident that both inhaled, percutaneous, intranasal, intraarticular and ophthalmic administered glucocorticoids have the potential to cause life threatening adrenal insufficiency. With few and sometimes conflicting data and study methodology the prevalence of adrenal...... insufficiency secondary to locally applied glucocorticoids is not clear. Adrenal insufficiency can only be correctly evaluated by a stimulation test, and has by this procedure been reported in up to 40-50% of patients treated with high-dose inhaled glucocorticoids. Medium- to low-dose inhaled glucocorticoids...... have been shown to cause adrenal suppression in 0-16% of patients. Glucocorticoid creams and nasal glucocorticoids can cause adrenal insufficiency, also when used within prescribed doses, but the frequency seems to be less than with inhaled glucocorticoids.

    Primary adrenal insufficiency (PAI) is a rare but severe and potentially life-threatening condition. No previous studies have characterized Portuguese patients with PAI. To characterize the clinical presentation, diagnostic workup, treatment and follow-up of Portuguese patients with confirmed PAI. This multicentre retrospective study examined PAI patients in 12 Portuguese hospitals. We investigated 278 patients with PAI (55.8% were females), with a mean age of 33.6 ± 19.3 years at diagnosis. The most frequent presenting clinical features were asthenia (60.1%), mucocutaneous hyperpigmentation (55.0%) and weight loss (43.2%); 29.1% of the patients presented with adrenal crisis. Diagnosis was established by high plasma ACTH and low serum cortisol in most patients (43.9%). The most common aetiology of PAI was autoimmune adrenalitis (61.0%). There were 38 idiopathic cases. Autoimmune comorbidities were found in 70% of the patients, the most frequent being autoimmune thyroiditis (60.7%) and type 1 diabetes mellitus (17.3%). Seventy-nine percent were treated with hydrocortisone (mean dose 26.3 ± 8.3 mg/day) mostly in three (57.5%) or two (37.4%) daily doses. The remaining patients were treated with prednisolone (10.1%), dexamethasone (6.2%) and methylprednisolone (0.7%); 66.2% were also on fludrocortisone (median dose of 100 µg/day). Since diagnosis, 33.5% of patients were hospitalized for disease decompensation. In the last appointment, 17.2% of patients had complaints (7.6% asthenia and 6.5% depression) and 9.7% had electrolyte disturbances. This is the first multicentre Portuguese study regarding PAI. The results emphasize the need for standardization in diagnostic tests and etiological investigation and provide a framework for improving treatment. © 2017 The authors.

    To evaluate the management of adrenal emergencies (AE) requiring parenteral glucocorticoid (GC) treatment in patients with chronic adrenal insufficiency (AI). Prospective, multicentre, questionnaire-based study. Participating patients (n = 150) with chronic AI were provided with a questionnaire on the management of emergency situations, which had to be completed and sent back in case of an AE. In addition, patients were contacted by phone on a regular basis. Fifty-nine AE in 39 patients were documented. The time interval from contact to arrival of a medical professional was 20 minutes (1-240). In total, in 43 AE, patients received parenteral GC by a medical professional. The time interval between showing the emergency card and GC injection by a medical professional was 60 minutes (5-360). A total of 26 patients administered GC by self-injection. The time from the beginning of symptoms to GC injection was significantly shorter in case of self-injection (self-injection vs injection by medical professional; 85 minutes [20-280] vs 232.5 minutes [1-3135]; P management, most of the patients (84%) indicated a need for an easier way of self-injection. While management of AE by both patients and medical professionals still shows high variability, patients profit from the option of self-injection. Patient care, including education of patients and health-professionals, as well as the way of GC administration, needs further optimization. © 2018 John Wiley & Sons Ltd.

    for diagnosing and treating adrenal insufficiency in patients with septic shock. SOURCES OF DATA: Articles published in Brazilian and foreign journals selected through these publications' websites and Medline, as well as references cited in key articles. SUMMARY OF THE FINDINGS: The literature reports a range betwen 17 and 54 % for the finding of adrenal insufficiency in patients with septic shock. There is no consensus for diagnosing adrenal insufficiency in patients suffering from critical diseases, particularly in patients with septic shock. The presence of volume-refractory and catecholamine-resistant septic shock suggests this condition, while basal cortisol under 25 µg/dl is a diagnostic criterion indicating adrenal insufficiency. The adrenal stimulation test is a useful resource for identifying patients with relative adrenal insufficiency. Our testing option for adrenal stimulation in children is the use of corticotropin in low doses (0.5 µg/1,73 m². An increase of less than 9 µg/dl in the value of postcorticotropin-stimulated cortisol suggests the presence of occult (relative adrenal insufficiency. In patients with septic shock presenting adrenal insufficiency, either suspected or confirmed, the administration of hydrocortisone in shock or stress doses can be vital for a favorable clinical outcome. CONCLUSIONS: The existing data, although controversial, already provides a basis to determine when to begin hormone replacement therapy, the serum level of cortisol accepted as adequate, and the choice of corticotropin doses for performing the adrenal stimulation test and diagnosing occult or relative adrenal insufficiency in patients with septic shock.

    Adrenal crisis is a life-threatening emergency that causes significant excess mortality in patients with adrenal insufficiency. Delayed recognition by medical staff of an impending adrenal crisis and failure to give timely hydrocortisone therapy within the emergency department continue to be commonly encountered, even in metropolitan teaching hospitals. Within the authors' institutions, several cases of poorly handled adrenal crises have occurred over the last 2 years. Anecdotal accounts from members of the Addison's support group suggest that these issues are common in Australia. This manuscript is a timely reminder for clinical staff on the critical importance of the recognition, treatment and prevention of adrenal crisis. The manuscript: (i) outlines a case and the clinical outcome of sub-optimally managed adrenal crisis, (ii) summarises the clinical features and acute management of adrenal crisis, (iii) provides recommendations on the prevention of adrenal crisis and (iv) provides guidance on the management of 'sick days' in patients with adrenal insufficiency. © 2016 Royal Australasian College of Physicians.

    Full Text Available Abstract Background Adrenal insufficiency is a rare and potentially lethal disease if untreated. Several clinical signs and biological markers are associated with glucocorticoid failure but the importance of these factors for diagnosing adrenal insufficiency is not known. In this study, we aimed to assess the prevalence of and the factors associated with adrenal insufficiency among patients admitted to an acute internal medicine ward. Methods Retrospective, case-control study including all patients with high-dose (250 μg ACTH-stimulation tests for suspected adrenal insufficiency performed between 2008 and 2010 in an acute internal medicine ward (n = 281. Cortisol values Results 32 patients (11.4% presented adrenal insufficiency; the others served as controls. Among all clinical and biological parameters studied, history of glucocorticoid withdrawal was the only independent factor significantly associated with patients with adrenal insufficiency (Odds Ratio: 6.71, 95% CI: 3.08 –14.62. Using a logistic regression, a model with four significant and independent variable was obtained, regrouping history of glucocorticoid withdrawal (OR 7.38, 95% CI [3.18 ; 17.11], p-value p-value 0.044, eosinophilia (OR 17.6, 95% CI [1.02; 302.3], p-value 0.048 and hyperkalemia (OR 2.41, 95% CI [0.87; 6.69], p-value 0.092. The AROC (95% CI was 0.75 (0.70; 0.80 for this model, with 6.3 (0.8 – 20.8 for sensitivity and 99.2 (97.1 – 99.9 for specificity. Conclusions 11.4% of patients with suspected adrenal insufficient admitted to acute medical ward actually do present with adrenal insufficiency, defined by an abnormal response to high-dose (250 μg ACTH-stimulation test. A history of glucocorticoid withdrawal was the strongest factor predicting the potential adrenal failure. The combination of a history of glucocorticoid withdrawal, nausea, eosinophilia and hyperkaliemia might be of interest to suspect adrenal insufficiency.

    Full Text Available Introduction. Many diseases and conditions can contribute to elevated liver enzymes. Common causes include viral and autoimmune hepatitis, fatty liver, and bile duct diseases, but, in uncommon cases like liver involvement in endocrine disorders, liver failure is also seen. Adrenal insufficiency is the rarest endocrine disorder complicating the liver. In the previously reported cases of adrenal insufficiency, mild liver enzymes elevation was seen but we report a case with severe elevated liver enzymes and liver failure due to adrenal insufficiency. Based on our knowledge, this is the first report in this field. Case Report. A 39-year-old woman was referred to emergency ward due to drowsiness and severe fatigue. Her laboratory tests revealed prothrombin time: 21 sec, alanine aminotransferase (ALT: 2339 IU/L, aspartate aminotransferase (AST: 2002 IU/L, and ALP: 90 IU/L. No common cause of liver involvement was discovered, and eventually, with diagnosis of adrenal insufficiency and corticosteroid therapy, liver enzymes and function became normal. Finally, the patient was discharged with good general condition. Conclusion. With this report, we emphasize adrenal insufficiency (primary or secondary as a reason of liver involvement in unexplainable cases and recommend that any increase in the liver enzymes, even liver failure, in these patients should be observed.

    Recently, there have been advances in understanding of the changes that occur in the hypothalamic-pituitary-adrenal axis during the different stages of critical disease. Such advances have led to a paradigm change, so that the aforementioned adaptations are no longer considered the result of adrenal axis activation, but a consequence of decreased cortisol metabolism illness. Knowledge of this new pathophysiological bases should lead to reconsider the diagnosis and treatment of adrenal insufficiency in critically ill patients, a condition poorly understood to date.

    A 27-year-old male was admitted with diabetic ketoacidosis and altered sensorium with slurring of speech and ataxia. He was managed with intravenous insulin and fluids and later shifted to basal bolus insulin regimen and during further evaluation was diagnosed to be suffering from primary hypothyroidism and adrenal insufficiency. He was started on thyroxin replacement and steroids only during stress. After three months of follow up he was clinically euthyroid. His glycemic control was adequate on oral anti-hyperglycemic drugs and adrenal insufficiency recovered. However, his thyrotropin levels were persistently elevated on adequate replacement doses of thyroxin. His repeat TSH was estimated after precipitating serum with polyethylene glycol which revealed normal TSH. Here we report reversible adrenal insufficiency with hypothyroidism with falsely raised TSH because of presence of heterophile antibodies in a case of poly glandular endocrinopathy syndrome.

    The effects of long-term replacement therapy of adrenal insufficiency (AI) are still a matter of controversy. In fact, the established glucocorticoid replacement regimens do not completely reproduce the endogenous hormonal production and the monitoring of AI treatment may be a challenge for the lack of reliable clinical and biochemical markers. Consequently, several AI patients are frequently exposed to relative glucocorticoid excess potentially leading to develop chronic complications, such as diabetes mellitus, dyslipidemia, hypertension and fragility fractures with consequent impaired QoL and increased mortality risk. This review deals with the pathophysiological and clinical aspects concerning the over-replacement therapy of primary and secondary AI. © 2017 European Society of Endocrinology.

    With the introduction of hormonal substitution therapy in the 1950s, adrenal insufficiency (AI) has been turned into a manageable disease in pregnant women. In fact, in the light of glucocorticoid replacement therapy and improved obstetric care, it is realistic to expect good maternal and fetal outcomes in patients with AI. However, there are still a number of challenges such as establishing the diagnosis of AI in pregnant women and optimizing the treatment of AI and related comorbidities prior to as well as during pregnancy. Clinical and biochemical diagnoses of a new-onset AI may be challenging because of overlapping symptoms of normal pregnancy as well as pregnancy-induced changes in cortisol values. Physiological changes occurring during pregnancy should be taken into account while adjusting the substitution therapy. The high proportion of reported adrenal crisis in pregnant women with AI highlights persistent problems in this particular clinical situation. Due to the rarity of the disease, there is no prospective data-guiding management of pregnancy in patients with known AI. The aim of this review is to summarize the maternal and fetal outcomes based on recently published case reports in patients with AI and to suggest a practical approach to diagnose and manage AI in pregnancy. © 2018 European Society of Endocrinology.

  11. Posaconazole-Induced Adrenal Insufficiency in a Case of Chronic Myelomonocytic Leukemia

    Directory of Open Access Journals (Sweden)

    2018-01-01

    Full Text Available Introduction. Posaconazole is an azole used in treatment and prophylaxis of a broad spectrum of fungal infections. Antifungals such as ketoconazole have been shown to cause primary adrenal insufficiency (AI as a result of direct inhibition on the steroidogenesis pathway. There is only one reported case of primary AI induced by posaconazole in a patient with mucormycosis. We report a case of posaconazole-related primary AI. Case. A 63-year-old man with chronic myelomonocytic leukemia was admitted for fatigue and intermittent nausea and vomiting. He had recently discontinued prophylactic posaconazole 300 mg daily. He was assessed for AI with a morning cortisol of 1.9 mcg/dL followed by a failed cosyntropin stimulation (CS test. Adrenocorticotropic hormone (ACTH level was 154.6 pg/mL with negative 21-hydroxylase antibodies. The patient’s symptoms improved with initiation of hydrocortisone and fludrocortisone. One year after discontinuation of posaconazole, he underwent a repeat CS test which showed normal adrenal function with normal ACTH at 34.1 pg/mL. Conclusion. In this case, we demonstrate that prolonged use of posaconazole is associated with primary AI. As use of posaconazole increases, knowledge of the potential risk of AI is important and must be included in the differential diagnosis when these patients present with hypotension, hypoglycemia, and failure to thrive.

    Full Text Available Purpose. Adrenocorticotropin- (ACTH- secreting pituitary carcinomas are rare and require multimodality treatment. The aim of this study was to report the response to various therapies and discuss the potential development of secondary adrenal insufficiency with cytotoxic chemotherapy. Methods. This report describes a man with a large silent corticotroph adenoma progressing to endogenous hypercortisolism and metastatic ACTH-secreting pituitary carcinoma over a period of 14 years. Results. Seven years after initial presentation, progressive tumor enlargement associated with the development of hypercortisolism mandated multiple pituitary tumor debulking procedures and radiotherapy. Testing of the Ki-67 proliferation index was markedly high and he developed a hepatic metastasis. Combination therapy with cisplatin and etoposide resulted in a substantial reduction in tumor size, near-complete regression of his liver metastasis, and dramatic decrease in ACTH secretion. This unexpectedly resulted in symptomatic secondary adrenal insufficiency. Conclusions. This is the first reported case of secondary adrenal insufficiency after use of cytotoxic chemotherapy for metastatic ACTH-secreting pituitary carcinoma. High proliferative indices may be predictive of dramatic responses to chemotherapy. Given the potential for such responses, the development of secondary adrenal insufficiency may occur and patients should be monitored accordingly.

    Full Text Available Tramadol is a synthetic, centrally acting analgesic. It is the most consumed narcotic drug that is prescribed in the world. Tramadol abuse has dramatically increased in Egypt. Long term use of tramadol can induce endocrinopathy. So, the aim of this study was to analyze the adrenal insufficiency induced by long term use of tramadol in experimental animals and also to assess its withdrawal effects through histopathological and biochemical genetic study. Forty male albino rats were used in this study. The rats were divided into 4 groups (control group, tramadol-treated group, and withdrawal groups. Tramadol was given to albino rats at a dose of 80 mg/kg body weight for 3 months and after withdrawal periods (7–15 days rats were sacrificed. Long term use of tramadol induced severe histopathological changes in adrenal glands. Tramadol decreased the levels of serum cortisol and DHEAS hormones. In addition, it increased the level of adrenal MDA and decreased the genetic expression of glutathione peroxidase and thioredoxin reductase in adrenal gland tissues. All these changes started to return to normal after withdrawal of tramadol. Thus, it was confirmed that long term use of tramadol can induce severe adrenal insufficiency.

    to 250 µg of intravenously administered adrenocorticotropic hormone are related to disease severity and, hence, mortality. METHODS: This is a retrospective study in a medical-surgical intensive care unit of a university hospital. We studied 69 consecutive patients with septic shock over a 1-yr period; these patients underwent a short 250-µg adrenocorticotropic hormone test because they exhibited >6 hours of progressive hemodynamic instability requiring repeated fluid challenges and vasopressor treatment to maintain blood pressure. The test was performed by intravenously injecting 250 µg of synthetic adrenocorticotropic hormone and measuring cortisol immediately before injection, 30 minutes post-injection and 60 minutes post-injection. RESULTS: The mean APACHE II score was 22±7. The intensive care unit mortality rate at day 28 was 55%. Median baseline cortisol levels (19 [11-27] µg/dL versus 24 [18-34] µg/dL, p=0.047 and median baseline cortisol/albumin ratios (7.6 [4.6-12.3] versus 13.9 [8.8-18.5]; p=0.01 were lower in survivors than in non-survivors. Responders and non-responders had similar baseline clinical data and outcomes. The variables that were significantly correlated with outcome based on the area under the ROC curves (AUC were APACHE II (AUC=0.67 [0.535 to 0.781], baseline cortisol (µg/dl (AUC=0.662 [0.536 to 0.773], peak cortisol (µg/dl (AUC=0.642 [0.515 to 0.755] and baseline cortisol/albumin (AUC=0.75 [0.621 to 0.849]. CONCLUSIONS: Increased basal cortisol is associated with mortality and disease severity. Cortisol responses upon adrenocorticotropic hormone stimulation were not related to outcome. The cortisol/albumin ratio does not predict unfavorable outcomes better than total cortisol levels or help to improve the accuracy of the adrenocorticotropic hormone test.

    Full Text Available Glucocorticoid replacement is needed for patients after adrenal surgery for Cushing’s syndrome; however, the adequate dosage is not easily determined. The patient was a 62-year-old woman who has had hypertension for 5 years and presented with heart failure due to hypertrophic cardiomyopathy. She consulted with us because of general fatigue, facial edema, and muscle weakness and was diagnosed with Cushing’s syndrome. A laparoscopic left adrenalectomy was performed, standard dosage of postoperative replacement was administered, and she was discharged with 30 mg/day of hydrocortisone (cortisol. However, she suffered from loss of appetite and was transferred to an emergency unit with the symptoms of adrenal insufficiency on postoperative day 15. After initial hydrocortisone replacement with 200 mg/day, the dosage was gradually decreased during hospitalization; however, reduction of hydrocortisone dosage lower than 60 mg/day was difficult because of nausea and fatigue. Her circadian cortisol profile after hydrocortisone administration showed delayed and lowered peaks, which suggested that hydrocortisone absorption in the intestine was impaired. Therefore, complicated heart failure may have led to the adrenal insufficiency in the patient. In such cases, we should consider postoperative administration of more than the standard dosage of hydrocortisone to avoid adrenal insufficiency after surgery for Cushing’s syndrome.

    A 38 year old man with history of obstructive sleep apnea and polycythaemia presented with hypercapnic respiratory failure that required intubation. He developed fever with infiltrates on chest radiography that required empiric antifungal therapy with fluconazole along with broad spectrum antibiotics. He developed acute adrenal insufficiency that recovered after fluconazole was stopped. It is believed that this complication of adrenal suppression attributable to fluconazole is underrecognised and it may be prudent to monitor all critically ill patients who are given fluconazole for this complication.

    Full Text Available It is important to fast diagnosis and management of the pediatric patients of the endocrine metabolic emergencies because the signs and symptoms of these disorders are nonspecific. Delayed diagnosis and treatment may lead to serious consequences of the pediatric patients, for example, cerebral dysfunction leading to coma or death of the patients with hypoglycemia, hypocalcemia, adrenal insufficiency, or diabetic ketoacidosis. The index of suspicion of the endocrine metabolic emergencies should be preceded prior to the starting nonspecific treatment. Importantly, proper diagnosis depends on the collection of blood and urine specimen before nonspecific therapy (intravenous hydration, electrolytes, glucose or calcium injection. At the same time, the taking of precise history and searching for pathognomonic physical findings should be performed. This review was described for fast diagnosis and proper management of hypoglycemic emergencies, hypocalcemia, adrenal insufficiency, and metabolic acidosis including diabetic ketoacidosis.

    Glucocorticoid replacement therapy in patients with adrenal insufficiency needs to be tailored to the individual patient based on body composition and clinical signs and symptoms as no objective method for assessment of treatment adequacy is available. Current treatment regimens are often not satisfactory, which is shown by the adverse metabolic profile and doubled mortality rates in treated adrenal insufficiency patients. Measurement of cortisol concentrations in hair reflect the long-term systemic cortisol exposure and may be of use in refinement of hydrocortisone treatment. We aimed to study whether long-term cortisol (hydrocortisone) levels, as measured in scalp hair, are similar in children with adrenal insufficiency and healthy children. We set up a case control study, measuring anthropometric characteristics and hair cortisol concentrations (HCC) in 54 hydrocortisone substituted children with adrenal insufficiency (AI patients) in the age of 4-18 years and 54 healthy children matched for gender and age. Mean HCC were significantly higher in AI patients compared with healthy controls (mean 13·3 vs 8·2 pg/mg, P = 0·02). AI patients also had a higher BMI (P < 0·001) and waist circumference (WC) (P = 0·02). HCC was significantly associated with BMI (P = 0·002) and WC (P = 0·002). HCC explained 13% of the difference in BMI and 29% of the difference in WC between AI patients and controls. Hydrocortisone-treated AI patients have increased HCC and adverse anthropometric characteristics compared with healthy controls. HCC measurement may be of value in identifying overtreatment and thereby improve hydrocortisone replacement therapy. © 2014 John Wiley & Sons Ltd.

    Tramadol is a synthetic, centrally acting analgesic. It is the most consumed narcotic drug that is prescribed in the world. Tramadol abuse has dramatically increased in Egypt. Long term use of tramadol can induce endocrinopathy. So, the aim of this study was to analyze the adrenal insufficiency induced by long term use of tramadol in experimental animals and also to assess its withdrawal effects through histopathological and biochemical genetic study.

    Full Text Available Adrenal insufficiency is a rare, but potentially fatal medical condition. In children the cause is most commonly congenital and in recent years a growing number of causative gene mutations have been identified resulting in a myriad of syndromes that share adrenal insufficiency as one of the main characteristics. The evolution of adrenal insufficiency is dependent on the variant and the particular gene affected, meaning rapid and accurate diagnosis is imperative for effective treatment of the patient. Common practice is for candidate genes to be sequenced individually, which is a time consuming process and complicated by overlapping clinical phenotypes. However, with the availability, and increasing cost effectiveness of whole exome sequencing there is the potential for this to become a powerful diagnostic tool. Here we report the results of whole exome sequencing of 43 patients referred to us with a diagnosis of familial glucocorticoid deficiency (FGD who were mutation negative for MC2R, MRAP and STAR the most commonly mutated genes in FGD. WES provided a rapid genetic diagnosis in 17/43 sequenced patients, for the remaining 60% the gene defect may be within intronic/regulatory regions not covered by WES or may be in gene(s representing novel aetiologies. The diagnosis of isolated or familial glucocorticoid deficiency was only confirmed in 3 of the 17 patients, other genetic diagnoses were adrenal hypo- and hyperplasia, Triple A and autoimmune polyendocrinopathy syndrome type I, emphasizing both the difficulty of phenotypically distinguishing between disorders of PAI and the utility of WES as a tool to achieve this.

    Coexistence of Addison's disease and systemic lupus erythematosus (SLE) is a rare occurrence with only few reported cases in the literature. We describe a 29-year-old woman who presented to us with clinical features of acute Addisonian crisis and SLE. Laboratory investigations were confirmatory of Addison's disease in a background of SLE. The patient made remarkable improvement on administration of steroids as replacement therapy for adrenal insufficiency and treatment of SLE. Clinicians need to have a high-index of suspicion of this possible coexistence in order to avoid the associated deleterious hemodynamic and metabolic consequences.

    Primary adrenal insufficiency (AI) requires hormone replacement therapy with fludrocortisone and hydrocortisone stimulating glucocorticoid (GR) and mineralocorticoid receptors (MR). Evidence from animal and human studies shows that MR function is crucial for cognitive function and mood. Regarding patients with AI, very little is known about the role of MR in cognitive function and mood. A repeated-measures within-subject design was used to determine whether cognitive function and mood are related to MR occupation in patients with AI. Intraindividually, patients were examined twice, with 1 week between testing days: once with fludrocortisone (high MR occupation) and once without fludrocortisone (low MR occupation). All patients kept their stable regimen of hydrocortisone. The assessment of cognitive function included executive function, attention, and verbal, visuospatial and working memory. Additionally, mood and blood pressure were measured. Verbal memory improved significantly during high MR occupation (after fludrocortisone intake) compared to low MR occupation [without fludrocortisone, t(29) = -2.1, p = 0.046]. There were trend level differences in the Number-Combination test [t(29) = -1.9, p = 0.074] and in the Stroop interference task [t(29) = -1.9, p = 0.068]. No significant differences in visuospatial and working memory were found. Furthermore, the current mood state was better during high MR occupation compared to low MR occupation [t(29) = -2.4, p = 0.023] as was diastolic blood pressure [F(2, 29) = 3.6, p = 0.07]. Cognitive function and mood in patients with AI depend in part on MR occupation. Because the medium effect size indicates a potential clinical significance, further studies should systematically examine which dosages of fludrocortisone are associated with optimal cognitive function and mood in AI patients. © 2015 S.

    We report a case of flexion contractures in a patient's legs secondary to postpartum hypopituitarism. A 56-year-old woman presented with a 3-year history of worsening flexion contractures of the hips and knees. On admission, her hips and knees could not be extended, and she had muscle stiffness and tenderness to palpation of the lower extremities. We first suspected stiff-person syndrome or Isaacs' syndrome because of her muscle stiffness. However, multiple hormones did not respond to stimulation tests, and an MRI of the brain showed atrophy of the pituitary gland with an empty sella. A subsequent interview revealed that she had suffered a severe hemorrhage while delivering her third child. She was diagnosed with panhypopituitarism and started on cortisol replacement therapy. After 1 week of treatment with hydrocortisone (10 mg/day), her symptoms quickly improved. We then added 75 μg/day of thyroid hormone. During the course of her treatment, autoantibodies against VGKC complex were found to be weakly positive. However, we considered the antibodies to be unrelated to her disease, because her symptoms improved markedly with low-dose steroid treatment. There are a few reports describing flexion contractures of the legs in patients with primary and secondary adrenal insufficiency. As these symptoms are similar to those seen in stiff-person syndrome, adrenal and pituitary insufficiency should be taken into account to achieve the correct diagnosis and treatment in patients with flexion contractures and muscle stiffness.

    Highly effective antiretroviral treatment has improved the life expectancy of human immunodeficiency virus (HIV) infected patients, but has led to an increase in the comorbidities related to aging, such as the chronic obstructive pulmonary disease (COPD). All this implies the need for a greater number of drugs and an increasing risk of drugs interactions with antiretroviral treatment, particularly protease inhibitors. We report a case of iatrogenic adrenal insufficiency interaction secondary to ritonavir and inhaled fluticasone in an HIV-infected patient with COPD. A review was made of the cases reported in adults in the medical literature (Medline) up to December 2012. A total of 34 cases were reported. The mean age was 4 years. The mean dose of ritonavir was 187 mg/day, while the fluticasone dose was 866 μg/day. The average time of the interaction between ritonavir and fluticasone was 8 months. In 85% of cases fluticasone was discontinued at the time of diagnosis of adrenal insufficiency/Cushing syndrome. Almost all (90%) patients had a complete resolution of the symptoms after changing the treatment. HIV-infected patients on antiretroviral therapy with protease inhibitor boosted with ritonavir which requires the use of inhaled corticosteroids, beclomethasone would be the best treatment option.

    Full Text Available Pituitary stalk interruption syndrome (PSIS involves the occurrence of a thin or absent pituitary stalk, hypoplasia of the adenohypophysis, and ectopic neurohypophysis. Diagnosis is confirmed using magnetic resonance imaging. Patients with PSIS have a variable degree of pituitary hormone deficiency and a wide spectrum of clinical manifestations. The clinical course of the disease in our patient is similar to that of a syndrome of inappropriate antidiuretic hormone secretion. This is thought to be caused by failure in the suppression of vasopressin secretion due to hypocortisolism. To the best of our knowledge, there is no case report of a patient with PSIS presenting with hyponatremia as the first symptom in Korean children. Herein, we report a patient with PSIS presenting severe recurrent hyponatremia as the first symptom, during adolescence and explain the pathophysiology of hyponatremia with secondary adrenal insufficiency.

    Wilson's disease typically presents symptoms associated with liver damage or neuropsychiatric disturbances, while endocrinologic abnormalities are rare. We report an unprecedented case of hypopituitarism in a patient with Wilson's disease. A 40-year-old woman presented with depression, general weakness and anorexia. Laboratory tests and imaging studies were compatible with liver cirrhosis due to Wilson's disease. Basal hormone levels and pituitary function tests indicated secondary hypothyroidism and adrenal insufficiency due to hypopituitarism. Brain MRI showed T2 hyperintense signals in both basal ganglia and midbrain but the pituitary imaging was normal. She is currently receiving chelation therapy along with thyroid hormone and steroid replacement. There may be a relationship between Wilson's disease and hypopituitarism. Copper deposition or secondary neuronal damage in the pituitary may be a possible explanation for this theory.

    Full Text Available Background. Addison's disease (AD, usually caused by an autoimmune process, has non-specific symptomatology. The deficiency of cortisol is manifested by weakness, anorexia, weight loss and orthostatic hypotension.  Early recognition is crucial as acute adrenal insufficiency is a life threatening state. Objectives. Analysis of the clinical picture, occurrence of symptoms before diagnosis, and the role of General Practitioner (GP in the diagnosis of AD. Material and methods. 23 patients with primary adrenal insufficiency (18F, 5M, aged 24-80 years, with an average of 46,6 years. A method of proprietary questionnaire was used. Results. The symptoms present prior to diagnosis were as follows: weakness (100% of patients, approximately 9,2 months before the diagnosis, fatigue (100%; 8,8 months respectively, loss of appetite (95,6%; 9,1 months, skin darkening (95,6%; 10 months, orthostatic hypotension (91,3%; 10,7 months, weight loss (86,9%; 6,8 months, low blood pressure (73,9%; 11 months, stomachache (69,6%; 4,6 months, nausea (65,2%; 3,6 months, increased appetite for salt (56,5%; 6,2 months, muscle pain (52,2%; 15,5 months, hyperpigmentation of buccal mucosa and gums (47,8%; 2,7 months, vomiting (43,5%; 3,4 months. Because of these symptoms patients went to different specialists, including GPs in 78,3% of cases. Suspicion of the disease in 34.8% put GP. Conclusion. The symptoms of AD develop slowly and are present long time before the right diagnosis is established. Difficulties in early diagnosis may result from a low specificity of most of the symptoms. The role of GP in establishing the right and early diagnosis of Addison's disease is crucial.

    2014-01-01

    Full Text Available A 73-year-old woman admitted to our hospital because of headache, poor appetite, malaise, weight loss, and vomiting was found to have central adrenal insufficiency and thyrotoxicosis due to silent thyroiditis. Polyuria developed after replacement with glucocorticoid (masked diabetes insipidus, which was controlled with nasal administration of desmopressin. Magnetic resonance imaging of the brain showed a large cystic pituitary mass (18 × 18 × 12 mm extending suprasellarly to the optic chiasm. Transsphenoidal surgery revealed that the pituitary tumor was Rathke’s cleft cyst. Following surgery, replacement with neither glucocorticoid nor desmopressin was needed any more. Therefore, it is suggested that Rathke’s cleft cyst is responsible for the masked diabetes insipidus and the central insufficiency. Furthermore, it is speculated that thyrotoxicosis with painless thyroiditis might induce changes from subclinical adrenal insufficiency to transiently overt insufficiency.

    Full Text Available Primary hypothyroidism related to morphological and volumetric abnormalities of the thyroid gland is one of the commonest of several endocrine dysfunctions in Williams-Beuren syndrome (WBS. We report a 10-month-old boy with WBS who presented with central hypothyroidism. During the neonatal period, he had prolonged jaundice, feeding difficulties and episodes of colic that continued during early infancy. Additionally, there was slowing of growth and mild developmental delay. He underwent surgical repair for supravalvular aortic stenosis at 6 months of age. An evaluation done to exclude cortisol deficiency before initiating levothyroxine lead to the detection of secondary adrenal insufficiency, unreported previously in WBS. In addition, insulin-like growth factor-1 (IGF-1 and IGF-binding protein-3 levels were low. This report of hypopituitarism in WBS indicates a need for complete evaluation of pituitary dysfunction in children with WBS.

    Chronic adrenal insufficiency (CAI) is characterized by a lack of glucocorticoid and mineralocorticoid production due to destroyed adrenal cortex cells. However, elevated cortisol secretion is thought to be a central part in a well-orchestrated immune response to stress. This raises the question to what extent lack of cortisol in CAI affects stress-related changes in immune processes. To address this question, 28 CAI patients (20 females) and 18 healthy individuals (11 females) (age: 44.3 ± 8.4 years) were exposed to a psychosocial stress test (Trier Social Stress Test: TSST). Half the patients received a 0.03 mg/kg body weight injection of hydrocortisone (HC) post-TSST to mimic a healthy cortisol stress response. Catecholamines and immune cell composition were assessed in peripheral blood and free cortisol measured in saliva collected before and repeatedly after TSST. CAI patients showed norepinephrine (NE) stress responses similar to healthy participants, however, epinephrine (E) as well as cortisol levels were significantly lower. HC treatment post-TSST resulted in cortisol increases comparable to those observed in healthy participants (interaction effects--NE: F=1.05, p=.41; E: F=2.56, p=.045; cortisol: F=13.28, pcortisol's central involvement in post-stress lymphocyte migration from blood into immune-relevant body compartments. As such, future studies should investigate whether psychosocial stress exposure may put CAI patients at an increased health risk due to attenuated immune responses to pathogens. Copyright © 2015.

    Anterior compartment syndrome (ACS) and rhabdomyolysis are rare complications of hypothyroid myopathy. We report the case of a young man with rapid onset of ACS who presented with simultaneous primary hypothyroidism and adrenal insufficiency associated with acute renal failure, hyponatremia, and hyperkalemia. A 22-year-old man presenting with a one-month history of tiredness, hyperpigmentation, and cramps in his calves was found to have severe bilateral foot drop. Investigations revealed severe primary hypothyroidism and adrenal insufficiency, renal failure, and evidence of rhabdomyolysis with myoglobinuria. Abnormal biochemical findings included serum sodium of 110 mM, serum potassium of 6.9 mM, and serum creatine kinase (CK) of >25,000 IU/L. Magnetic resonance imaging (MRI) of his legs showed changes of myonecrosis confined to anterior tibial muscles typical of ACS. After treatment with intravenous fluids, potassium-lowering therapies, thyroxine, and hydrocortisone, his renal and metabolic function returned to normal, but irreversible bilateral foot drop persisted. A young man with primary hypothyroidism, adrenal insufficiency, hyponatremia, and hyperkalemia presented with severe myopathy, such that muscle necrosis, apparently confined to the anterior tibial compartment on MRI, led to rhabdomyolysis, acute renal failure, and irreversible bilateral peroneal nerve damage. It is possible that other patients with primary hypothyroidism and marked elevations of CK without widespread myopathy or rhabdomyolysis may demonstrate evidence of differential muscle effects in the anterior compartment when assessed by MRI, but that this patient also had adrenal insufficiency raises the possibility that this was a contributing factor. Severe thyroid myopathy and rhabdomyolysis may be associated with anatomic susceptibility to ACS, particularly in the presence of concomitant adrenal insufficiency. MRI examination reveals a distinctive appearance of myonecrosis confined to

  15. A Comparison of Salivary Steroid Levels during Diagnostic Tests for Adrenal Insufficiency

    Full Text Available Numerous diagnostic tests are used to evaluate the hypothalamic-pituitary-adrenal axis (HPA axis. The gold standard is still considered the insulin tolerance test (ITT, but this test has many limitations. Current guidelines therefore recommend the Synacthen test first when an HPA axis insufficiency is suspected. However, the dose of Synacthen that is diagnostically most accurate and sensitive is still a matter of debate. We investigated 15 healthy men with mean/median age 27.4/26 (SD ±4.8 years, and mean/median BMI (body mass index 25.38/24.82 (SD ±3.2 kg/m2. All subjects underwent 4 dynamic tests of the HPA axis, specifically 1 μg, 10 μg, and 250 μg Synacthen (ACTH tests and an ITT. Salivary cortisol, cortisone, pregnenolone, and DHEA (dehydroepiandrosterone were analysed using liquid chromatography-tandem mass spectrometry. During the ITT maximum salivary cortisol levels over 12.5 nmol/l were found at 60 minutes. Maximum cortisol levels in all of the Synacthen tests were higher than this; however, demonstrating that sufficient stimulation of the adrenal glands was achieved. Cortisone reacted similarly as cortisol, i.e. we did not find any change in the ratio of cortisol to cortisone. Pregnenolone and DHEA were higher during the ITT, and their peaks preceded the cortisol peak. There was no increase of pregnenolone or DHEA in any of the Synacthen tests. We demonstrate that the 10 μg Synacthen dose is sufficient stimulus for testing the HPA axis and is also a safe and cost-effective alternative. This dose also largely eliminates both false negative and false positive results.

    The aim of this study was to characterize the brain ultrasonographic findings of late-onset circulatory dysfunction (LCD) due to adrenal insufficiency (AI) in preterm infants. Among the 257 preterm infants born at <33 weeks of gestation between December 2009 and February 2014 at our institution, 35 preterm infants were diagnosed with AI. Brain ultrasonographic findings were retrospectively analyzed before and after LCD in 14 preterm infants, after exclusion of the other 21 infants with AI due to the following causes: death (n=2), early AI (n=5), sepsis (n=1), and patent ductus arteriosus (n=13). Fourteen of 257 infants (5.4%) were diagnosed with LCD due to AI. The age at LCD was a median of 18.5 days (range, 9 to 32 days). The last ultrasonographic findings before LCD occurred showed grade 1 periventricular echogenicity (PVE) in all 14 patients and germinal matrix hemorrhage (GMH) with focal cystic change in one patient. Ultrasonographic findings after LCD demonstrated no significant change in grade 1 PVE and no new lesions in eight (57%), grade 1 PVE with newly appearing GMH in three (21%), and increased PVE in three (21%) infants. Five infants (36%) showed new development (n=4) or increased size (n=1) of GMH. Two of three infants (14%) with increased PVE developed cystic periventricular leukomalacia (PVL) and rapid progression to macrocystic encephalomalacia. LCD due to AI may be associated with the late development of GMH, increased PVE after LCD, and cystic PVL with rapid progression to macrocystic encephalomalacia.

  17. Increased Cardiovascular Risk in Patients with Adrenal Insufficiency: A Short Review

    Directory of Open Access Journals (Sweden)

    Amir-Hossein Rahvar

    2017-01-01

    Full Text Available Cardiovascular disease (CVD is the most common cause of death in the world. Recent studies have shown an association between adrenal insufficiency (AI and increased cardiovascular risk (CVR. Patients with AI receive glucocorticoid (GC replacement therapy which can lead to varying levels of blood cortisol. It was shown that these imbalances in blood cortisol may lead to a higher prevalence of coronary heart disease, major adverse coronary events, and increased mortality. GC substitution is essential in the treatment of AI without which the disease has been shown to be fatal. The most frequently used GC formula for replacement therapy is hydrocortisone (HC. There is no uniform opinion on hydrocortisone replacement therapy. Alternative GC such as prednisolone is also in use. Overreplacement of GC may lead to adverse effects including obesity, high blood pressure, and hyperglycaemia. Outcome may vary between primary and secondary AI mainly due to differences in the renin-angiotensin-aldosterone system (RAAS. Furthermore, decreased blood levels of cortisol may lead to a compensatory secretion of inflammatory mediators such as Interleukin-1 (IL-1, Interleukin-6 (IL-6, and/or tumor-necrosis factor (TNF. Physicians and patients should be properly educated about the increased risk of CVD in patients with AI.

    Patients with adrenal insufficiency (AI) require life-long replacement therapy with exogenous glucocorticoids. Several studies have shown impaired subjective health status in these patients as well as increased morbidity and mortality risk, which may be caused by glucocorticoid over-replacement. As a measure of long-term cortisol exposure, the usefulness of hair cortisol analysis in patients receiving glucocorticoid replacement therapy was investigated. Hair samples, demographics, medical history and perceived stress scale questionnaires were collected from 93 patients across North America diagnosed with primary or secondary AI. Sixty-two household partners served as a control group. Cortisol was measured in the proximal 2 cm of hair, representing the most recent 2 months of exposure. A modified enzyme immunoassay was used for the measurement of cortisol. The male patients had significantly higher hair cortisol levels than the male controls (P cortisol content correlated significantly with glucocorticoid dose (r = 0·3, P cortisol content correlates with hydrocortisone (HC) dose in patients with AI. Our results suggest that some AI patients may be over-treated and hence may be at risk for the adverse effects of cortisol. Measurement of HC in hair may become a useful monitoring tool for long-term cortisol exposure in patients treated with glucocorticoids. © 2011 Blackwell Publishing Ltd.

    Full Text Available Background Glucocorticoid replacement is commonly required to treat secondary adrenal insufficiency after surgical resection of unilateral cortisol-secreting adrenocortical adenomas. Here, we describe a patient with unilateral cortisol-secreting adenomas in which the preoperative use of mifepristone therapy was associated with recovery of the hypothalamic–pituitary–adrenal (HPA axis, eliminating the need for postoperative glucocorticoid replacement. Case Presentation A 66-year-old Caucasian man with type 2 diabetes mellitus, hyperlipidemia, hypertension, and obesity was hospitalized for Fournier's gangrene and methicillin-resistant Staphylococcus aureus sepsis. Abdominal computed tomography scan revealed three left adrenal adenomas measuring 1.4, 2.1, and 1.2 cm and an atrophic right adrenal gland. Twenty-four-hour urinary free cortisol level was elevated (237 µg/24 hours, reference range 0–50 µg/24 hours. Hormonal evaluation after resolution of the infection showed an abnormal 8 mg overnight dexamethasone suppression test (cortisol postdexamethasone 14.5 µg/dL, suppressed adrenocorticotropic hormone (ACTH; <5 pg/mL, reference range 7.2–63.3 pg/mL, and low-normal dehydroepiandrosterone sulfate (50.5 µg/dL, male reference range 30.9–295.6 µg/dL. Because of his poor medical condition and uncontrolled diabetes, his Cushing's syndrome was treated with medical therapy before surgery. Mifepristone therapy was started and, within five months, his diabetes was controlled and insulin discontinued. The previously suppressed ACTH increased to above normal range accompanied by an increase in dehydroepiandrosterone sulfate levels, indicating recovery of the HPA axis and atrophic contralateral adrenal gland. The patient received one precautionary intraoperative dose of hydrocortisone and none thereafter. Two days postoperatively, ACTH (843 pg/mL and cortisol levels (44.8 µg/dL were significantly elevated, reflecting an appropriate HPA axis

    Full Text Available Background. Multidrug-resistant tuberculosis (MDR-TB is a major public health care concern that affects the life of millions of people around the world. The association of tuberculosis and adrenal insufficiency is well known; however, it is thought to be less prevalent every time. A spike in TB incidence and a lack of evidence of this association in patients with MDR-TB call for reassessment of an illness (adrenal dysfunction that if not diagnosed could seriously jeopardize patients’ health. Objective. To determine the prevalence of adrenocortical insufficiency in patients with MDR-TB using the low-dose (1 μg ACTH stimulation test at baseline and at 6–12 months of follow-up after antituberculosis treatment and culture conversion. Methods. A total of 48 men or women, aged ≥18 years (HIV-negative patients diagnosed with pulmonary MDR-TB were included in this prospective observational study. Blood samples for serum cortisol were taken at baseline and 30 and 60 minutes after 1 μg ACTH stimulation at our tertiary level university hospital before and after antituberculosis treatment. Results. Forty-seven percent of subjects had primary MDR-TB; 43.8% had type 2 diabetes; none were HIV-positive. We found at enrollment 2 cases (4.2% of adrenal insufficiency taking 500 nmol/L as the standard cutoff point value and 4 cases (8.3% alternatively, using 550 nmol/L. After antituberculosis intensive phase drug-treatment and a negative mycobacterial culture (10.2±3.6 months adrenocortical function was restored in all cases. Conclusions. In patients with MDR-TB, using the low-dose ACTH stimulation test, a low prevalence of mild adrenal insufficiency was observed. After antituberculosis treatment adrenal function was restored in all cases. Given the increasing and worrying epidemic of MDR-TB these findings have important clinical implications that may help clinicians and patients make better decisions when deciding to test for adrenocortical

    The authors report the case of a 69-year-old man with chronic obstructive pulmonary disease and previous pulmonary tuberculosis, who presented to the emergency department with abdominal and low back pain, anorexia and weight loss, rapidly evolving into shock. An initial CT scan revealed pulmonary condensation with associated cavitation and an iliopsoas mass suggestive of a psoas abscess. He was admitted in an intensive care unit unit; after a careful examination and laboratory assessment, the aetiology was yet undisclosed. MRI showed multiple retroperitoneal lymphadenopathies, bulky nodular adrenal lesions and bilateral iliac lytic lesions. Hypocortisolism was detected and treated with steroids. A CT-guided biopsy to the psoas mass and lytic lesions identified infiltration of non-small lung carcinoma. The patient died within days. Psoas metastases and adrenal insufficiency as initial manifestations of malignancy are rare and can be misdiagnosed, particularly in the absence of a known primary tumour. 2015 BMJ Publishing Group Ltd.

    Cholesterol side-chain cleavage enzyme (P450scc) deficiency is a rare genetic disorder causing primary adrenal insufficiency with or without a 46,XY disorder of sexual development (DSD). Herein, we report a case of the combination of primary adrenal insufficiency, a DSD (testes with female external genitalia in a setting of a 47,XXY karyotype), and Angelman syndrome. Comprehensive genetic analyses were performed, including a single nucleotide polymorphism microarray and whole-exome sequencing. In vitro studies were performed to evaluate the pathogenicity of the novel mutation that was identified by whole-exome sequencing. The patient was found to have segmental uniparental disomy (UPD) of chromosome 15 explaining her diagnosis of Angelman syndrome. Whole-exome sequencing further revealed a novel homozygous intronic variant in CYP11A1, the gene encoding P450scc, found within the region of UPD. In vitro studies confirmed that this variant led to decreased efficiency of CYP11A1 splicing. We report the first case of the combination of 2 rare genetic disorders, Angelman syndrome, and P450scc deficiency. After 20 years of diagnostic efforts, significant advances in genetic diagnostic technology allowed us to determine that these 2 disorders originate from a unified genetic etiology, segmental UPD unmasking a novel recessive mutation in CYP11A1. © 2018 S.

    Full Text Available Myotonic dystrophy type 1 (DM1 is an autosomal dominant multisystem disease affecting muscles, the eyes and the endocrine organs. Diabetes mellitus and primary hypogonadism are endocrine manifestations typically seen in patients with DM1. Abnormalities of hypothalamic–pituitary–adrenal (HPA axis have also been reported in some DM1 patients. We present a case of DM1 with a rare combination of multiple endocrinopathies; diabetes mellitus, a combined form of primary and secondary hypogonadism, and dysfunction of the HPA axis. In the present case, diabetes mellitus was characterized by severe insulin resistance with hyperinsulinemia. Glycemic control improved after modification of insulin sensitizers, such as metformin and pioglitazone. Hypogonadism was treated with testosterone replacement therapy. Notably, body composition analysis revealed increase in muscle mass and decrease in fat mass in our patient. This implies that manifestations of hypogonadism could be hidden by symptoms of myotonic dystrophy. Our patient had no symptoms associated with adrenal deficiency, so adrenal dysfunction was carefully followed up without hydrocortisone replacement therapy. In this report, we highlight the necessity for evaluation and treatment of multiple endocrinopathies in patients with DM1.

    Mitotane (o,p'-DDD; 1-[2-chlorophenyl]-1-[4-chlorophenyl]-2,2-dichloroethane) has been used in the treatment of Cushing's syndrome due to adrenal hyperfunction and it the drug of choice for adrenocortical carcinoma. The object of this investigation is to study the biotransformation of o,p'-DDD and p,p'-DDD in dogs and bovine adrenal cortex to explain its selective toxicity and mechanism of action. The in vitro biotransformation of 14 C-labeled o,p'-DDD and p,p'-DDD by dog and bovine adrenal cortex as studied. Of the cortex subcellular fractions, the cytosol fraction was found to be the most active in metabolizing the substrates, followed by the mitochondrial fraction. This metabolism including that in cytosolic fractions, did not take place with boiled enzyme preparations and required an NADPH generating system. This study has been directed towards establishing the metabolic activation mechanism which may account for the adrenocorticolytic effect of mitotane in contrast to detoxication by the liver. HPLC and TLC metabolic profiles have been generated from incubations of bovine and dog adrenal cortex homogenates and their subfractions for 14 C-labeled p,p'-DDD, o,p'-DDD and its monochloroethylene derivative, o,p'-DDMU

    Hypoglycemia can be a symptom in patients with Addison's disease. The common regimen of replacement therapy with oral glucocorticoids results in unphysiological low cortisol levels in the early morning, the time of highest insulin sensitivity. Therefore patients with Addison's disease are at risk for unrecognized and potentially severe nocturnal hypoglycemia also because of a disturbed counterregulatory function. Use of a continuous glucose monitoring system (CGMS) could help to adjust hydrocortisone treatment and to avoid nocturnal hypoglycemia in these patients. Thirteen patients with Addison's disease were screened for hypoglycemia wearing a CGMS for 3-5 days. In one patient we identified a hypoglycemic episode at 3:45 a.m. with a blood glucose level of 46 mg/dL, clearly beneath the 95% tolerance interval of minimal glucose levels between 2 and 4 a.m. (53.84 mg/dL). After the hydrocortisone replacement scheme was changed, the minimum blood glucose level between 2 and 4 a.m. normalized to 87 mg/dL. Continuous glucose monitoring can detect nocturnal hypoglycemia in patients with primary adrenal insufficiency and hence prevent in these patients an impaired quality of life and even serious adverse effects.

    The insulin tolerance test (ITT) is the gold standard for diagnosing adrenal insufficiency (AI) after pituitary surgery. The ITT is unpleasant for patients, requires close medical supervision and is contraindicated in several comorbidities. The aim of this study was to analyze whether tumor size, remission rate, preoperative, and early postoperative baseline hormone concentrations could serve as predictors of AI in order to increase the diagnostic accuracy of morning serum cortisol. This prospective study enrolled 70 consecutive patients with newly diagnosed pituitary adenomas. Thirty-seven patients had nonfunctioning pituitary adenomas (NPA), 28 had prolactinomas and 5 had somatotropinomas. Thyroxin (T4), thyrotropin (TSH), prolactin, follicle-stimulating hormone (FSH), luteinizing hormone (LH), testosterone, and insulin-like growth factor 1 (IGF-I) were measured preoperatively and on the sixth postoperative day. Serum morning cortisol was measured on the third postoperative day (CORT3) as well as the sixth postoperative day (CORT6). Tumor mass was measured preoperatively and remission was assessed 3 months after surgery. An ITT was performed 3 to 6 months postoperatively. Remission was achieved in 48% of patients and AI occurred in 51%. Remission rates and tumor type were not associated with AI. CORT3 had the best predictive value for AI (area under the curve (AUC) 0.868, sensitivity 82.4%, specificity 83.3%). Tumor size, preoperative T4, postoperative T4, and TSH were also associated with AI in a multivariate regression model. A combination of all preoperative and postoperative variables (excluding serum cortisol) had a sensitivity of 75.0% and specificity of 77.8%. The predictive power of CORT3 substantially improved by adding those variables into the model (AUC 0.921, sensitivity 94.1%, specificity 78.3%, PPV 81.9%, NPV of 92.7%). In a subgroup analysis that included only female patients with NPA, LH had exactly the same predictive value as CORT3. The addition

    Adjustment of daily hydrocortisone dose on clinical criteria lacks sensitivity for fine tuning. Long term hydrocortisone (HC) over-replacement may lead to increased morbidity and mortality in patients with adrenal insufficiency (AI). Biochemical criteria may help detecting over- or under-replacement but have been poorly evaluated. Multicenter, institutional, pharmacokinetic study on ACTH and cortisol plasma profiles during HC replacement in 27 AI patients compared to 29 matched controls. All AI patients were administered HC thrice daily at doses of 6, 10 and 14 mg/m2/d. Blood samples were drawn hourly from 0800h to 1900h. The main outcome measures were: i) plasma peak cortisol and cortisol area under the curve (AUC) in AI patients compared to controls, ii) correlations between cortisol AUC vs single-point cortisol or ACTH decrease from baseline (ΔACTH) and iii) the predictive value of the two latters for obtaining AI patients' cortisol AUC in the control range. Cortisol peaks were observed 1h after each HC intake and a dose response was demonstrated for cortisol peak and cortisol AUC. The comparison of AI patients' cortisol AUC to controls showed that 81.5% AI patients receiving 6mg/m2/d were adequately replaced, whereas most patients receiving higher doses were over-replaced. The correlation coefficient between 1000h/1400h cortisol concentrations and 0800-1900h cortisol AUC were 0.93/0.88 respectively, whereas the 0800-1200h ΔACTH fairly correlated with 0800-1900h cortisol AUC (R = 0.57). ROC curve analysis indicated that the 1000h and 1400h cortisol concentrations best predicted over-replacement. Patients receiving a 6mg/m2 hydrocortisone daily dose exhibited the most physiological daytime cortisol profile. Single point plasma cortisol correlated with daytime cortisol AUC in AI patients. Although hydrocortisone dose should be currently determined on clinical grounds, our data suggest that single point plasma cortisol may be an adjunct for further hydrocortisone

    A young Marshallese woman presented with the insidious development of fever, cough, fatigue, profound weakness, massive weight loss, cachexia, alopecia, amenorrhea, and periumbilical hyperpigmentation. Limited laboratory studies revealed anemia, leukocytosis, and hyponatremia. Imaging studies, as well as digital photographs, transmitted over the Internet, using the secure Pacific Island Health Care Project (PIHCP), store-and-forward telemedicine system, suggested the diagnosis of disseminated tuberculosis, and antimycobacterial antibiotics were begun. Sputum cultures eventually grew Mycobacterium tuberculosis. Based on the constellation of clinical signs and symptoms, the transmitted images, and limited laboratory data, adrenal tuberculosis (Addison's disease) with adrenal insufficiency was diagnosed and corticosteroids were initiated. The patient responded dramatically This case underscores the utility of telemedicine in the diagnosis and treatment of patients with unusual conditions, rarely seen today in the United States, from remote sites in the Developing World.

    Salt-wasting represents a relatively common cause of emergency admission in infants and may result in life-threatening complications. Neonatal kidneys show low glomerular filtration rate and immaturity of the distal nephron leading to reduced ability to concentrate urine. A retrospective chart review was conducted for infants hospitalized in a single Institution from 1(st) January 2006 to 31(st) December 2015. The selection criterion was represented by the referral to the Endocrinology Unit for hyponatremia (serum sodium <130 mEq/L) of suspected endocrine origin at admission. Fifty-one infants were identified. In nine infants (17.6 %) hyponatremia was related to unrecognized chronic gastrointestinal or renal salt losses or reduced sodium intake. In 10 infants (19.6 %) hyponatremia was related to central nervous system diseases. In 19 patients (37.3 %) the final diagnosis was congenital adrenal hyperplasia (CAH). CAH was related to 21-hydroxylase deficiency in 18 patients, and to 3β-Hydroxysteroid dehydrogenase (3βHSD) deficiency in one patient. Thirteen patients (25.5 %) were affected by different non-CAH salt-wasting forms of adrenal origin. Four familial cases of X-linked adrenal hypoplasia congenita due to NROB1 gene mutation were identified. Two unrelated girls showed aldosterone synthase deficiency due to mutation of the CYP11B2 gene. Two unrelated infants were affected by familial glucocorticoid deficiency due to MC2R gene mutations. One girl showed pseudohypoaldosteronism related to mutations of the SCNN1G gene encoding for the epithelial sodium channel. Transient pseudohypoaldosteronism was identified in two patients with renal malformations. In two infants the genetic aetiology was not identified. Emergency management of infants presenting with salt wasting requires correction of water losses and treatment of electrolyte imbalances. Nevertheless, the differential diagnosis may be difficult in emergency settings, and sometimes hospitalized infants

    Dual-release hydrocortisone (DR-HC) provides physiological cortisol exposure, leading to an improvement of anthropometric and metabolic parameters. The aim of the study was to evaluate the effects of DR-HC on insulin secretion and sensitivity and cardiometabolic risk, indirectly expressed by the visceral adiposity index (VAI). Retrospective analysis of 49 patients, 13 with primary and 36 with secondary adrenal insufficiency (AI), respectively, on conventional glucocorticoid treatment at baseline and switched to DR-HC for 36 months. Overall, 24 patients had AI-pre-diabetes (impaired fasting glucose, impaired glucose tolerance and the combination), and 25 had AI-normal glucose tolerance (NGT). Clinical and metabolic parameters, including VAI, insulin secretion and sensitivity indexes (fasting insulinaemia, AUC 2 h insulinaemia , oral disposition index [Dio] and ISI-Matsuda), were evaluated. In patients with AI-NGT and AI-prediabetes, a significant decrease in BMI (P = .017 and P 36 and P = .043) was, respectively, observed. In addition, in prediabetic patients, only we found a significant decrease in insulinaemia (P = .014), AUC 2 h insulinaemia (P = .038) and VAI (P = .001), in concomitance with a significant increase in DIo (P = .041) and ISI-Matsuda (P = .038). Long-term DR-HC therapy is associated with an improvement in insulin secretion and sensitivity in patients with prediabetes. However, all patients appear to benefit from the treatment in terms of improvement of metabolic and anthropometric parameters. Larger studies are required to confirm our preliminary data. © 2018 John Wiley & Sons Ltd.

    Patients with treated adrenal insufficiency (AI) have increased morbidity and mortality rate. Our goal was to improve outcome by developing a once-daily (OD) oral hydrocortisone dual-release tablet with a more physiological exposure-time cortisol profile. The aim was to compare pharmacokinetics and metabolic outcome between OD and the same daily dose of thrice-daily (TID) dose of conventional hydrocortisone tablets. We conducted an open, randomized, two-period, 12-wk crossover multicenter trial with a 24-wk extension at five university hospital centers. The trial enrolled 64 adults with primary AI; 11 had concomitant diabetes mellitus (DM). The same daily dose of hydrocortisone was administered as OD dual-release or TID. We evaluated cortisol pharmacokinetics. Compared with conventional TID, OD provided a sustained serum cortisol profile 0-4 h after the morning intake and reduced the late afternoon and the 24-h cortisol exposure. The mean weight (difference = -0.7 kg, P = 0.005), systolic blood pressure (difference = -5.5 mm Hg, P = 0.0001) and diastolic blood pressure (difference: -2.3 mm Hg; P = 0.03), and glycated hemoglobin (absolute difference = -0.1%, P = 0.0006) were all reduced after OD compared with TID at 12 wk. Compared with TID, a reduction in glycated hemoglobin by 0.6% was observed in patients with concomitant DM during OD (P = 0.004). The OD dual-release tablet provided a more circadian-based serum cortisol profile. Reduced body weight, reduced blood pressure, and improved glucose metabolism were observed during OD treatment. In particular, glucose metabolism improved in patients with concomitant DM.

    It is rare for a patient to present with adrenal insufficiency secondary to bilateral adrenal metastases from a malignant colorectal tumor. An 82-year-old Japanese man presented to our hospital with high fever and malaise. He was receiving oral chemotherapy for the treatment of rectal cancer with multiple metastases. Computed tomography showed new bilateral adrenal gland metastases. A rapid adrenocorticotropic hormone (ACTH) test showed adrenal insufficiency. Treatment with hydrocortisone provided immediate symptom improvement. Adrenal insufficiency secondary to bilateral adrenal metastases from rectal cancer is rare. A rapid ACTH test is useful to diagnose adrenal insufficiency. The incidence of adrenal insufficiency may be underestimated in patients with multiple metastasis. Appropriate therapy with adrenal corticosteroid hormone supplementation may lead to a significant improvement in the patient's symptoms and quality of life. Copyright © 2016 The Author(s).

    Adenoma, myelolipoma, phaeochromocytoma, metastases, adrenocortical carcinoma, neuroblastoma, and lymphoma account for the majority of adrenal neoplasms that are encountered in clinical practice. A variety of imaging methods are available for evaluating adrenal lesions including ultrasound, computed tomography (CT), magnetic resonance imaging (MRI), and nuclear medicine techniques such as meta-iodobenzylguanidine (MIBG) scintigraphy and positron-emission tomography (PET). Lipid-sensitive imaging techniques such as unenhanced CT and chemical shift MRI enable detection and characterization of lipid-rich adenomas based on an unenhanced CT attenuation of ≤10 HU and signal loss on opposed-phase compared to in-phase T1-weighted images, respectively. In indeterminate cases, an adrenal CT washout study may differentiate adenomas (both lipid-rich and lipid-poor) from other adrenal neoplasms based on an absolute percentage washout of >60% and/or a relative percentage washout of >40%. This is based on the principle that adenomas show rapid contrast washout while most other adrenal neoplasms including malignant tumours show slow contrast washout instead. 18 F-2-fluoro-2-deoxy-D-glucose–PET ( 18 FDG-PET) imaging may differentiate benign from malignant adrenal neoplasms by demonstrating high tracer uptake in malignant neoplasms based on the increased glucose utilization and metabolic activity found in most of these malignancies. In this review, the multi-modality imaging appearances of adrenal neoplasms are discussed and illustrated. Key imaging findings that facilitate lesion characterization and differentiation are emphasized. Awareness of these imaging findings is essential for improving diagnostic confidence and for reducing misinterpretation errors.

    Full Text Available Domesticated species have an attenuated behavioral and physiological stress response compared to their wild counterparts, but the genetic mechanisms underlying this change are not fully understood. We investigated gene expression of a panel of stress response-related genes in five tissues known for their involvement in the stress response: hippocampus, hypothalamus, pituitary, adrenal glands and liver of domesticated White Leghorn chickens and compared it with the wild ancestor of all domesticated breeds, the Red Junglefowl. Gene expression was measured both at baseline and after 45 min of restraint stress. Most of the changes in gene expression related to stress were similar to mammals, with an upregulation of genes such as FKBP5, C-FOS and EGR1 in hippocampus and hypothalamus and StAR, MC2R and TH in adrenal glands. We also found a decrease in the expression of CRHR1 in the pituitary of chickens after stress, which could be involved in negative feedback regulation of the stress response. Furthermore, we observed a downregulation of EGR1 and C-FOS in the pituitary following stress, which could be a potential link between stress and its effects on reproduction and growth in chickens.We also found changes in the expression of important genes between breeds such as GR in the hypothalamus, POMC and PC1 in the pituitary and CYP11A1 and HSD3B2 in the adrenal glands. These results suggest that the domesticated White Leghorn may have a higher capacity for negative feedback of the HPA axis, a lower capacity for synthesis of ACTH in the pituitary and a reduced synthesis rate of corticosterone in the adrenal glands compared to Red Junglefowl. All of these findings could explain the attenuated stress response in the domesticated birds.

    Full Text Available Purpose: Prader Willi syndrome (PWS is a rare genetic condition that has concurrent endocrinological insufficiencies. The presence of growth hormone deficiency has been well documented, but adrenal insufficiency (AI is not widely reported. A review was conducted to investigate its prevalence and relevance in PWS in both adults and children. Methodology: A literature review was performed with the search terms “Prader-Willi syndrome” and “adrenal insufficiency”. Results: The review found studies disagree on the prevalence and method of investigation of AI in PWS. Case studies demonstrate that patients with PWS are at risk of premature death, often secondary to respiratory infections. The possibility that this may be the result of the inability to mount an effective cortisol response has been studied, with some evidence confirming AI in PWS patients. Most reports agreed AI is present in PWS, however, Farholt et al. showed no HPA axis dysfunction in adults, suggesting that perhaps it is rare in adults, and children should be the focus of further studies. Conclusion: AI is present in some patients with PWS. Further research is required to ensure optimal treatment can be implemented and to prevent premature deaths related to adrenal insufficiency. Clinicians should have a low threshold for testing the adrenal axis and considering treatment for adrenal insufficiency in PWS patients.

    Vertebral insufficiency fractures may result from excessive loading of normal and routine loading of osteoporotic spines. Fractures occur when the mechanical load exceeds the vertebral compressive strength, i.e., the maximum load a vertebra can tolerate. Vertebral compressive strength is determined by trabecular bone density and the size of end-plate area. Both parameters can be measured non-invasively by quanti-tative computed tomography (QCT). In 75 patients compressive strength (i.e., trabecular bone density and endplate area) of the vertebra L3 was determined using QCT. In addition, conventional radiographs of the spines were analysed for the prevalence of insufficiency fractures in each case. By relating fracture prevalence to strength, 3 fracture risk groups were found: a high-risk group with strength values of L3 5 kN and a fracture risk near 0 percent. Biomechanical measurements and model calculations indicate that spinal loads of 3 to 4 kN at L3/4 will be common in everyday activities. These data and the results described above suggest that spines with strength values of L3<3 kN are at an extremely high risk of insufficiency fractures in daily life. Advantages of fracture risk assessment by strength determination over risk estimation based on clinically used trabecular bone density measurements are discussed. (author). 18 refs.; 4 figs

    Full Text Available Nonclassic congenital adrenal hyperplasia (NCAH due to P450c21 (21-hydroxylase deficiency is a common autosomal recessive disorder. This disorder is due to mutations in the CYP21A2 gene which is located at chromosome 6p21. The clinical features predominantly reflect androgen excess rather than adrenal insufficiency leading to an ascertainment bias favoring diagnosis in females. Treatment goals include normal linear growth velocity and “on-time” puberty in affected children. For adolescent and adult women, treatment goals include regularization of menses, prevention of progression of hirsutism, and fertility. This paper will review key aspects regarding pathophysiology, diagnosis, and treatment of NCAH.

    When a diagnosis of adrenal disorder is suspected on the basis of clinical manifestations and/or laboratory findings, computed tomography (CT) is generally accepted as the imaging procedure of choice for visualization of adrenal areas and localization of lesions. Sonography keeps an important role in discovering adrenal masses during investigation for other suspected abnormality (incidentaloma). 131 I MIBG scintigraphy provides an efficious mean of pheochromocytoma localization and functional characterization. These non invasive procedures have greatly reduced the need for arteriography and venography; adrenal venous sampling is still an useful method for localizing either a tumor or hyperplasia related to primary aldosteronism. MR imaging and CT are nearly equivalent in the detection of adrenal masses: besides MR imaging has a potential for characterization of adrenal masses which might be useful, especially in distinguishing adrenal adenomas from malignant neoplasms, obviating, in some cases, the need of CT guided adrenal biopsy [fr

    Long-term follow-up of growth and development after acute lymphoblastic leukaemia (ALL) in childhood has previously been limited to the prepubertal period. This study describes pubertal growth, final height and the spontaneous secretion of GH in girls treated for ALL, including CNS irradiation with 24 GY. Ten girls, treated earlier for ALL, experienced the menarche at a mean age of 12.2 years. This is significantly earlier than the mean for Swedish girls. Prepubertal growth was near normal after the end of therapy for leukaemia. Mean final height was -1.7 SD, which is 1.5 SD less than at onset and 1.0 SD less than 1 year after the end of treatment. Thirteen other girls had a blunted spontaneous secretion of GH, several years after treatment for ALL; there was no increase in GH secretion during puberty. These results suggest that girls who have been treated for ALL, including CNS irradiation, have a relative GH insufficiency. This insufficiency becomes obvious only when girls cannot respond to the increased need for GH during the pubertal spurt.

  17. Ultradian rhythms in pituitary and adrenal hormones: their relations to sleep.

    Gronfier, C; Brandenberger, G

    1998-02-01

    Sleep and circadian rhythmicity both influence the 24-h profiles of the main pituitary and adrenal hormones. From studies using experimental strategies including complete and partial sleep deprivation, acute and chronic shifts in the sleep period, or complete sleep-wake reversal as occurs with transmeridian travel or shift-work, it appears that prolactin (PRL) and growth hormone (GH) profiles are mainly sleep related, while cortisol profile is mainly controlled by the circadian clock with a weak influence of sleep processes. Thyrotropin (TSH) profile is under the dual influence of sleep and circadian rhythmicity. Recent studies, in which we used spectral analysis of sleep electroencephalogram (EEG) rather than visual scoring of sleep stages, have evaluated the temporal associations between pulsatile hormonal release and the variations in sleep EEG activity. Pulses in PRL and in GH are positively linked to increases in delta wave activity, whereas TSH and cortisol pulses are related to decreases in delta wave activity. It is yet not clear whether sleep influences endocrine secretion, or conversely, whether hormone secretion affects sleep structure. These well-defined relationships raise the question of their physiological significance and of their clinical implications.

    Considering that insufficient platelet inhibition is related to thrombotic complications after coronary angiography, we hypothesized that the extent of platelet inhibition by antiplatelet agents is related to the occurrence of silent embolic cerebral infarction (SECI) after coronary angiography. Among the patients scheduled for coronary artery bypass surgery, we retrospectively analyzed the location of SECI on diffusion-weighted imaging of 272 patients, which was performed after coronary angiography, as a presurgical evaluation in Phase 1 study. In Phase 2 study, we have prospectively recruited 102 patients to compare the extent of platelet inhibition measured by the VerifyNow system among patients with and without SECI. SECI is observed in 45 patients (16.5%) in Phase 1 and 17 (16.7%) in Phase 2. The lesions were slightly more frequent in the right hemisphere. In the Phase 2 study, aspirin reaction units and P(2)Y(12) reaction units were higher in the patients with SECI than those without (aspirin reaction units: 490±72 versus 446±53, P=0.03; P(2)Y(12) reaction units: 352±65 versus 300±77, P=0.009). The incidence of SECI increased with the number of resistant antiplatelets; resistance to both antiplatelet agent (50%), resistance to 1 antiplatelet agent (22%), and no resistance (4%; P=0.023). From the result of logistic regression, higher aspirin reaction units, white blood cell count, low hemoglobin, and nonresponsiveness to antiplatelet agents were independent risk factors. Insufficient platelet inhibition after administration of antiplatelet agents is related with SECI appearing after coronary angiography.

    2017-10-01

    Full Text Available Ginseng effectively regulates the immune response and the hormonal changes due to stress, thus maintaining homeostasis. In addition to suppressing the occurrence of psychological diseases such as anxiety and depression, ginseng also prevents stress-associated physiological diseases. Recent findings have revealed that ginseng is involved in adjusting the hypothalamic–pituitary–adrenal axis and controlling hormones, thus producing beneficial effects on the heart and brain, and in cases of bone diseases, as well as alleviating erectile dysfunction. Recent studies have highlighted the potential use of ginseng in the prevention and treatment of chronic inflammatory diseases such as diabetes, rheumatoid arthritis, and allergic asthma. However, the mechanism underlying the effects of ginseng on these stress-related diseases has not been completely established. In this review, we focus on the disease pathways caused by stress in order to determine how ginseng acts to improve health. Central to our discussion is how this effective and stable therapeutic agent alleviates the anxiety and depression caused by stress and ameliorates inflammatory diseases.

    Atrazine, one of the most widely used herbicides, has been proved to interfere with sexual hormones. However few studies have considered the effects of atrazine on adrenal hormones (AH). In this study, rare minnow (Gobiocypris rarus) was exposed to 0, 3, 10, 33, 100 and 333microg/l atrazine for 28 days. The histopathology of kidney and gill was examined and the expressions of AHs-related genes including Na(+),K(+)-ATPase, glucocorticoid receptor (gr), heat shock protein 70 (hsp70), and heat shock protein 90 (hsp90) in kidney and gill were quantitatively determined. Histopathological observation revealed obvious lesions in gill including hyperplasia, necrosis in epithelium region, aneurysm and lamellar fusion at concentrations as low as 10microg/l. The observed lesions in kidney included extensive expansion in the lumen, degenerative and necrotic changes of the tubular epithelia, shrinkage of the glomerulus as well as increase of the Bowman's space at concentrations as low as 10microg/l. The expressions of Na(+),K(+)-ATPase, gr, hsp70 and hsp90 in the kidney of females were significantly decreased at all concentrations. For males, the expressions of hsp90 in the kidney of all treated groups were significantly down-regulated, while gr at all concentrations and hsp70 at 10, 33, 100microg/l were significantly up-regulated. However in the gill, the expressions of these genes were not significantly different from the control. These results indicated that exposure to atrazine caused impairments of kidney and gill of fish at environmental related concentrations. Histopathological lesions could partly attribute to the changes of the expressions of AHs-related genes in kidney. We concluded also that atrazine is a potential AHs-disruptor and AHs-related genes in kidney of fish could be used as sensitive molecular biomarkers.

    As a traditional concept of Chinese medicine (CM), the theory of "Shen (Kidney) controlling bones" has been gradually proven. And in modern allopathic medicine, the multiple mechanisms of bone growth, development and regeneration align with the theory. Shen defifi ciency as a pathological condition has a negative effect on the skeleton of body, specififi cally the disorder of bone homeostasis. Present studies indicate that Shen defifi ciency shares a common disorder characterized by dysfunction of hypothalamic-pituitary-adrenal (HPA) axis. HPA axis may be an important regulator of bone diseases with abnormal homeostasis. Therefore, we posit the existence of hypothalamic-pituitary-adrenal-osteo-related cells axis: cells that comprise bone tissue (osteo-related cells) are targets under the regulation of HPA axis in disorder of bone homeostasis. Chinese herbs for nourishing Shen have potential in the development of treatments for disorder of bone homeostasis.

    In newborn infants, normal adrenal glands are characterized by a relatively thin echogenic center surrounded by a thick, hypoechoic cortical rim as seen on ultrasound (US). Various disorders involving the neonatal adrenal gland include adrenal hemorrhage, hyperplasia, cyst, Wolman's disease, and congenital neuroblastoma.

    In newborn infants, normal adrenal glands are characterized by a relatively thin echogenic center surrounded by a thick, hypoechoic cortical rim as seen on ultrasound (US). Various disorders involving the neonatal adrenal gland include adrenal hemorrhage, hyperplasia, cyst, Wolman's disease, and congenital neuroblastoma. Adrenal hemorrhage is the most common cause of an adrenal mass in the neonate, though differentiation between adrenal hemorrhage and neuroblastoma is in many cases difficult. We describe characteristic US, CT and MR imaging findings in neonates with various adrenal disorders.

    Full Text Available Incidentally discovered adrenal masses, or adrenal incidentalomas, have become a common clinical problem owing to wide application of radiologic imaging techniques. This definition encompasses a heterogeneous spectrum of pathologic entities, including primary adrenocortical and medullary tumors, benign or malignant lesions, hormonally active or inactive lesions, metastases, and infections. Once an adrenal mass is detected, the clinician needs to address two crucial questions: is the mass malignant, and is it hormonally active? This article provides an overview of the diagnostic clinical approach and management of the adrenal incidentaloma. Mass size is the most reliable variable to distinguish benign and malignant adrenal masses. Adrenalectomy should be recommended for masses greater than 4.0 cm because of the increased risk of malignancy. Adrenal scintigraphy has proved useful in discriminating between benign and malignant lesions. Finally, fine-needle aspiration biopsy is an important tool in the evaluation of oncological patients and it may be useful in establishing the presence of metastatic disease. The majority of adrenal incidentalomas are non-hypersecretory cortical adenomas but an endocrine evaluation can lead to the identification of a significant number of cases with subclinical Cushing's syndrome (5-15%, pheochromocytoma (1.5-13% and aldosteronoma (0-7%. The first step of hormonal screening should include an overnight low dose dexamethasone suppression test, the measure of urinary catecholamines or metanephrines, serum potassium and, in hypertensive patients, upright plasma aldosterone/plasma renin activity ratio. Dehydroepiandrosterone sulfate measurement may show evidence of adrenal androgen excess.

    We report a 10 years old boy, admitted with a history of asthenia, anorexia and weight loss of 4 kg. Initial laboratory work up showed metabolic acidosis and hyponatremia. The patient had no circadian rhythm of serum cortisol and an adrenal stimulation test confirmed the presence of adrenal insufficiency. Anti-adrenal antibodies were positive. Treatment with cortisol and fluorocortisone resulted in a complete remission of symptoms (Rev Méd Chile 2002; 130: 901-6).

    We analyzed the relationship between Mink-S27 gene polymorphism and children with cardiac insufficiency. From April 2013 to April 2015, we enrolled 73 cases of children with cardiac insufficiency for this study, and all 73 were placed in the observation group. 76 normal cases were selected for the control group. Restriction fragment length polymorphism (RFLP) was used to make polymorphism analysis of the Mink-S27. Our results showed no significant differences in Mink-S27 genotype and allele distribution in both observation and control groups (p>0.05). In lesion samples collected from children with cardiac insufficiency, we detected significant difference in AA, CC genotype frequency and allele frequency between the observation group and the control group (prelatively high. GNAS2 gene polymorphism was associated with the prevalence of cardiac insufficiency in children. And also the patients' condition was correlated to the frequency of different genotypes and alleles.

    Because of their special physical and chemical properties, the adrenal secretory products were among the first hormonal substances to be measured by methods other than bioassay. Over the past several years, the development of sensitive and specific methods of hormone assay dependent on the use of radionuclides has revolutionized investigative and clinical endocrinology. While the capacity of defining most abnormalities of adrenal function antedates hormone measurement and adrenal imaging utilizing radioisotopes, the availability of such methods has greatly facilitated and made more precise the diagnostic approach to patients with suspected adrenal dysfunction. As an example of how clinical and laboratory considerations can be integrated into a rational approach to the diagnosis of adrenal disease, the problem of suspected adrenal hyperfunction is analyzed in light of current understanding of its pathophysiology. Reflection demonstrates that suspected primary aldosteronism and adrenal insufficiency are equally amenable to such an approach

    Studies of people living with HIV who are homeless or unstably housed show a high prevalence of food insufficiency (>50%) and associated poor health outcomes; however, most evidence is in the form of cross-sectional studies. To better understand this issue, we conducted a longitudinal study to examine the impact of food insufficiency and housing instability on overall physical and mental health-related quality of life (HRQoL) among people living with HIV in Ontario. Six hundred and two adults living with HIV were enrolled in the Positive Spaces, Healthy Places study and followed from 2006 to 2009. Interviewer-administered questionnaires were used, and generalized linear mixed-effects models constructed to examine longitudinal associations between food insufficiency, housing instability and physical and mental HRQoL. At baseline, 57% of participants were classified as food insufficient. After adjusting for potential confounders, longitudinal analyses revealed a significant, negative association between food insufficiency and physical and mental HRQoL outcomes, respectively [effect size (ES) with 95% confidence interval (CI): (ES = -2.1, CI = -3.9,-0.3); (ES = -3.5, CI = -6.1,-1.5)]. Furthermore, difficulties meeting housing costs were shown to have additional negative impacts on mental HRQoL. Food insufficiency is highly prevalent among people living with HIV in Ontario, particularly for those with unstable housing. This vulnerable group of individuals is in urgent need of changes to current housing programmes, services and policies, as well as careful consideration of their unmet nutritional needs.

    PAX6 is a master gene of ocular development and postnatal ocular equilibrium. Congenital aniridia is the hallmark of PAX6 gene haploinsufficiency (Chr. 11 p. 13), but PAX6-associated aniridia is a profound, progressive pan-ocular developmental disorder often leading to blindness. There is congenital visual impairment with advancing loss of vision mainly due to secondary glaucoma and to corneal blindness caused by limbal stem cell insufficiency (LSCI). LSCI leads to ARK (aniridia-related keratopathy), which typically develops in four stages. Incipient LSCI with vessels starting to grow into the cornea can be imaged by fluorescein anterior segment angiography, which enables fine vessels to be more easily detected than by routine slit lamp examination, especially in patients with nystagmus. Thus, clinical stage 1 ARK is often diagnosed at stage 2 by angiography. Corneal neovascularizations often start at the 12 and 6 positions and subsequently progress circumferentially, not at the 3 and 9 positions as previously believed. Anterior segment angiography can provide an easily standardizable tool for monitoring progress, treatment-induced regress or stabilization of ARK. Especially in children, angiography could be used to monitor new treatment regimens for reducing LSCI. Angiography could enable treatment to begin earlier to preserve corneal hemostasis. In addition, the fact that vascularization often starts at the subpalpebral 6 and 12 positions as opposed to the 3 and 9 positions raises more questions concerning factors that promote LSCI and related corneal injuries.

    The traditional techniques to treat thoracic insufficiency syndrome (TIS) are not able to stabilize or improve chest wall size or pulmonary function while allowing spine growth. To this end, vertical expandable prosthetic titanium rib (VEPTR) was specifically designed to treat TIS by allowing growth of the thoracic cavity and control/correction of spine deformity. The purpose of this study was to determine quality of life (QOL) of children with TIS and its impact on their parents before and after implantation of the VEPTR and also compare these results to those of healthy children. As part of the original multicenter evaluation of the VEPTR, a Child Health Questionnaire (CHQ) was collected preoperatively on 45 patients who were subsequently treated with expansion thoracoplasty using the VEPTR. The average age was 8.2 +/- 2.6 years, and the parent form of the CHQ was filled out by the primary caretaker. Patients were divided into 3 diagnostic categories: rib fusion (n = 15), hypoplastic thorax syndromes (n = 17), and progressive spinal deformity (n = 13). There were significant differences between the study patients and healthy children in physical domains. Compared with parents of healthy children, parents of children with TIS experienced more limitations on their time and emotional lives due to their children's health problems. There were no significant differences in CHQ before and after the surgery except for a significant decrease in the self-esteem among a subgroup of patients with hypoplastic thorax syndromes. There were no significant differences in postoperative QOL between patients who had VEPTR-related complications and patients who did not have the complications. The children with TIS had lower physical scores and higher caregiver burden scores than healthy children. However, the scores in psychosocial domains were similar to those in healthy children. Our study demonstrated that QOL of children and burden of care in their parents remained the same after

    The visualization of functioning adrenocortical tissue by scintigraphy became possible with the introduction of radioiodinated cholesterol derivatives. According to the literature, there is evidence that one of these iodinated cholesterols, 6-β-iodomethyl-nor-cholesterol, concentrates in the adrenal cortex to a much greater extent than 131 I-19-odocholesterol. Results comparing both radiopharmaceuticals are described. The authors investigated the possibility of increasing the uptake of iodinated cholesterol using simultaneous ACTH and the 'cholesterol side-chain cleavage enzymeblocker': aminoglutethimide. The results of adrenal scintigraphy performed in 37 patients are described. Finally, the literature on adrenal scintigraphy is reviewed, and results reported in various studies are compared. (Auth.)

    Disorders of the adrenal glands frequently have secondary neurological manifestations, while some diseases that involve the central nervous system are accompanied by adrenal gland dysfunction. Excessive corticosteroid secretions in primary or secondary Cushing's syndrome causes muscle weakness and behavioral disturbances, such as emotional lability and sometimes depression, while adrenal insufficiency may cause fatigue, weakness, and depression. Adrenoleukodystrophy and adrenoneuromyelopathy are X-linked recessive disorders of the metabolism of very long chain fatty acids that manifest with white matter abnormalities of the brain, myelopathy and/or neuropathy, as well as adrenal insufficiency. Other disorders of the adrenal glands include hyperaldosteroidism, which may cause weakness from hypokalemia. Dysfunction of the adrenal medulla causes excessive or deficient secretion of catecholamines, primarily causing cardiovascular symptoms. This chapter reviews the clinical manifestations and diagnostic aspects and treatment of the various disorders of the adrenal glands. Some of the congenital adrenal diseases are also discussed. © 2014 Elsevier B.V. All rights reserved.

    Twenty-five patients affected by adrenal glands pathology underwent CT and MRI: 6 nonfuctioning adenomas, 2 Cushing's adenomas, 2 Conn's adenomas, 6 metastases, 3 cystis, 2 carcinomas (Cushing's syndrome), 1 Lymphoma and 3 pheochromocytomas. Diagnosis was subsequently confirmed either at surgery, or autopsy, or with needle biopsy. In all cases normal adrenal glands and pathological lesions were showed by MRI. T1 signal intensity and mass diameter were compared with T2 signal intensity, represented by the intensity ratio between the adrenal mass vs normal hepatic parenchyma. MRI signal intensity, usually high in case of malignancy and low in adenomas, shows a mean value which is much wider than that referred to mass diameter evaluation (carcinoma is larger than adenoma); for this reason those findings have proved to be insufficiently accurate for adrenal tissue characterization, even for the evaluation of cysts and pheochromocytomas. In the same cases CT showed higher accuracy

    In 30 cases of chronic adrenal insufficiency (Addison's disease) CT of the adrenal glands was performed using a fourth generation scanner and a 2 mm slice thickness. Adrenal glands were visualized in all the cases. In 26 patients the adrenals were atrophied; the adrenal shape was abnormal in 21 patients. In 15 patients CT disclosed calcifications in one or both glands, which were particularly frequent in patients over the age of 50. Atrophy of adrenal glands was of high occurrence in cases of autoimmune origin. (orig.) [de

    Full Text Available Various neurological and psychiatric manifestations have been recorded in children with adrenal disorders. Based on literature review and on personal case-studies and case-series we focused on the pathophysiological and clinical implications of glucocorticoid-related, mineralcorticoid-related, and catecholamine-related paediatric nervous system involvement. Childhood Cushing syndrome can be associated with long-lasting cognitive deficits and abnormal behaviour, even after resolution of the hypercortisolism. Exposure to excessive replacement of exogenous glucocorticoids in the paediatric age group (e.g., during treatments for adrenal insufficiency has been reported with neurological and magnetic resonance imaging (MRI abnormalities (e.g., delayed myelination and brain atrophy due to potential corticosteroid-related myelin damage in the developing brain and the possible impairment of limbic system ontogenesis. Idiopathic intracranial hypertension (IIH, a disorder of unclear pathophysiology characterised by increased cerebrospinal fluid (CSF pressure, has been described in children with hypercortisolism, adrenal insufficiency, and hyperaldosteronism, reflecting the potential underlying involvement of the adrenal-brain axis in the regulation of CSF pressure homeostasis. Arterial hypertension caused by paediatric adenomas or tumours of the adrenal cortex or medulla has been associated with various hypertension-related neurological manifestations. The development and maturation of the central nervous system (CNS through childhood is tightly regulated by intrinsic, paracrine, endocrine, and external modulators, and perturbations in any of these factors, including those related to adrenal hormone imbalance, could result in consequences that affect the structure and function of the paediatric brain. Animal experiments and clinical studies demonstrated that the developing (i.e., paediatric CNS seems to be particularly vulnerable to alterations induced by

    The reported incidence of bone complications after radiation therapy is quite low. The most commonly seen bone complication is insufficiency fractures of the pubis and sacrum. Treatment of insufficiency fractures consists of conservative care, and mineral replacement may be useful. The resolution of symptoms takes at least one year with these treatments. Vascular damage has an important role in the etiology of late radiation injury in normal tissues. Progressive ischemic changes further weaken the bone structure, which can cause fractures, and healing is also delayed. Pentoxifylline is a methylxanthine derivative that is shown to increase tissue blood flow. Here, we present a 63-year-old male patient with pelvic insufficiency fractures due to postoperative pelvic irradiation for rectal adenocarcinoma. The patient received pelvic radiotherapy to a total dose of 50.4 Gy with concomitant 5-FU. Six months after the completion of radiotherapy, the patient presented with severe pelvic pain. Pelvic magnetic resonance imaging (MRI) demonstrated abnormal signal intensity with insufficiency fractures at the sacrum and bone marrow edema near the fractures, but not an abnormal intensity that revealed bone metastases. Neither distant nor locoregional recurrence was observed at his work-up. The final diagnosis was insufficiency fractures of the pelvic bones owing to irradiation, and pentoxifylline (400 mg, 3 times daily, peroral, 1,200 mg/day) was used for eight months as treatment. Dramatic clinical improvement was obtained in six months, and objective healing was revealed with MRI. We concluded that pentoxifylline is a cost-effective drug with minimal adverse effects in treating radiation damage of bone. (author)

    Neuroendocrine deficiencies have been implicated in fibromyalgia (FM). In the present study, adrenal androgen metabolites and their relationship with health status in FM were investigated. For comparison, serum levels of other implicated neuroendocrine mediators were correlated with health status. Fifty-seven consecutive women with FM completed the Fibromyalgia Impact Questionnaire (FIQ). Fasting blood samples were taken for measurement of dehydroepiandrosterone sulphate (DHEAS), free testosterone (T), cortisol, serotonin and insulin-like growth factor-1. Normal value for DHEAS and T were obtained from 114 controls. DHEAS levels were decreased significantly in pre- and postmenopausal patients (PBMI correlated positively with pain (PBMI, the correlation between age adjusted DHEAS and pain was no longer significant. Hyposecretion of adrenal androgens was documented in FM. This was more pronounced in obese patients. Low serum androgen levels correlated with poor health status in FM. Longitudinal studies are needed to elucidate whether these are cause and/or effect relationships.

    We evaluated the relationship between the ultradian rhythm of sleep and the secretory episodes of pituitary-adrenal hormones. Prolactin (PRL) and TSH exhibited opposite phase relationships with delta waves, PRL increasing and TSH decreasing when delta waves developed. Delta waves never increased together with an increase in cortisol secretion. They oscillated independently from each other throughout the 24 hour period, but when they were present at the same time, they oscillated in opposing phases. Concerning growth hormone (GH), its major peak which occurred shortly after sleep onset in association with the first slow wave sleep episode was blunted during sleep deprivation. However, this blunting was compensated during the day, so that the amount of GH secreted during a 24-hr period was similar whether or not a person had slept during the night. The physiological significance and the clinical implications of the various relationships of the endocrine systems with sleep are poorly known.

    Full Text Available Abstract Background Lung maturation is modulated by several factors, including glucocorticoids. Expression of hypothalamic-pituitary-adrenal (HPA axis-related components, with proposed or described local regulatory systems analogous to the HPA axis, was reported in peripheral tissues. Here, HPA axis-related genes were studied in the mouse developing lung during a period overlapping the surge of surfactant production. Methods Expression of genes encoding for corticotropin-releasing hormone (CRH, CRH receptors (CRHR 1 and 2beta, CRH-binding protein, proopiomelanocortin (POMC, melanocortin receptor 2 (MC2R, and glucocorticoid receptor was quantified by real-time PCR and localized by in situ hydridization in fetal lungs at gestational days (GD 15.5, 16.5, and 17.5, and was also quantified in primary mesenchymal- and epithelial cell-enriched cultures. In addition, the capability of CRH and adrenocorticotropic hormone (ACTH to stimulate pulmonary expression of enzymes involved in the adrenal pathway of glucocorticoid synthesis was addressed, as well as the glucocorticoid production by fetal lung explants. Results We report that all the studied genes are expressed in fetal lungs according to different patterns. On GD 15.5, Mc2r showed peaks in expression in samples that have previously presented high mRNA levels for glucocorticoid synthesizing enzymes, including 11beta-hydroxylase (Cyp11b1. Crhr1 mRNA co-localized with Pomc mRNA in cells surrounding the proximal epithelium on GD 15.5 and 16.5. A transition in expression sites toward distal epithelial cells was observed between GD 15.5 and 17.5 for all the studied genes. CRH or ACTH stimulation of genes involved in the adrenal pathway of glucocorticoid synthesis was not observed in lung explants on GD 15.5, whereas CRH significantly increased expression of 21-hydroxylase (Cyp21a1 on GD 17.5. A deoxycorticosterone production by fetal lung explants was observed. Conclusions Temporal and spatial

    One of the major causes of chronic adrenal insufficiency (Addison's disease) is tuberculous adrenalopathy. Since sonography and computed tomography have become generally available in recent years and are of potential help in the diagnosis of this disease the merits of these methods are discussed in the light of 2 cases of adrenal tuberculosis, followed by a review of the literature. Adrenal calcification is the most significant, although not specific sign of adrenal insufficiency due to tuberculosis. Computed tomography has proven to be the method of choice in the non-invasive diagnosis of tuberculous adrenalopathy and in the monitoring of tuberculostatic treatment in this disease. Sonography is helpful as a preliminary investigation. (Author)

    Autoimmune adrenalitis, or autoimmune Addison disease (AAD), is the most prevalent cause of primary adrenal insufficiency in the developed world. AAD is rare and can easily be misdiagnosed as other conditions. The diagnosis depends on demonstrating inappropriately low cortisol production and the presence of high titers of adrenal cortex autoantibodies (ACAs), along with excluding other causes of adrenal failure using other tests as necessary. The treatment corticosteroid replacement, and the prognosis following the treatment is the same as the normal population. Spontaneous recovery of adrenal function has been described but is rare.

    Neonatal adrenal hematoma is a rare condition, most frequently caused by trauma. We report three cases of adrenal hematoma admitted to the Neonatology and Neonatal Intensive Care Unit in the A. Harouchi Children's Hospital, the Ibn Rushd University Hospital in Casablanca, Morocco, over a 2-year period from January 2011 to December 2012. The average age of these patients was 5 days. The clinical presentations were diverse; the most common manifestations were intense jaundice in one case, acute adrenal insufficiency in one case, and severe anemia in the other case. Abdominal ultrasonography was used to confirm the diagnosis and monitor adrenal hemorrhage in all the patients. Analysis of clinical, laboratory, and ultrasonography data showed a favorable prognosis in all the patients. Based on these observations, we discuss the risk factors, clinical presentations, progression and management of neonatal adrenal hemorrhage. Copyright © 2014. Published by Elsevier SAS.

    This study aimed to identify potentially important factors in explaining burnout in nursing that have been insufficiently studied or ignored. A three-round Delphi study via e-mail correspondence was conducted, with a group of 40 European experts. The e-Delphi questionnaire consisted of 52 factors identified from a literature review. Experts rated and scored the importance of factors in the occurrence of burnout and the degree of attention given by researchers to each of the variables listed, on a six-point Likert scale. We used the agreement percentage (>80%) to measure the level of consensus between experts. Furthermore, to confirm the level of consensus, we also calculated mean scores and modes. Regardless of the degree of consensus reached by the experts, we have calculated the mean of the stability of the answers for each expert (individual's qualitative stability) and the mean of the stability percentages of the experts (qualitative group stability). The response rate in the three rounds was 93.02% (n = 40). Eight new factors were suggested in the first round. After modified, the e-Delphi questionnaire in the second and third rounds had 60 factors. All the factors reached the third round with a consensus level above 80% in terms of the attention that researchers gave them in their studies. Moreover, the data show a total mean qualitative group stability of 96.21%. In the third round 9 factors were classified by experts as 'studied very little', 17 as 'studied little' and 34 as 'well studied'. Findings show that not all the factors that may influence nursing burnout have received the same attention from researchers. The panel of experts has identified factors that, although important in explaining burnout, have been poorly studied or even forgotten. Our results suggest that further study into factors such as a lack of recognition of part of the tasks that nurses perform, feminine stereotype or excessive bureaucracy is needed for a better understanding of this

    Objective This study aimed to identify potentially important factors in explaining burnout in nursing that have been insufficiently studied or ignored. Methods A three-round Delphi study via e-mail correspondence was conducted, with a group of 40 European experts. The e-Delphi questionnaire consisted of 52 factors identified from a literature review. Experts rated and scored the importance of factors in the occurrence of burnout and the degree of attention given by researchers to each of the variables listed, on a six-point Likert scale. We used the agreement percentage (>80%) to measure the level of consensus between experts. Furthermore, to confirm the level of consensus, we also calculated mean scores and modes. Regardless of the degree of consensus reached by the experts, we have calculated the mean of the stability of the answers for each expert (individual's qualitative stability) and the mean of the stability percentages of the experts (qualitative group stability). Results The response rate in the three rounds was 93.02% (n = 40). Eight new factors were suggested in the first round. After modified, the e-Delphi questionnaire in the second and third rounds had 60 factors. All the factors reached the third round with a consensus level above 80% in terms of the attention that researchers gave them in their studies. Moreover, the data show a total mean qualitative group stability of 96.21%. In the third round 9 factors were classified by experts as ‘studied very little’, 17 as ‘studied little’ and 34 as 'well studied' Conclusion Findings show that not all the factors that may influence nursing burnout have received the same attention from researchers. The panel of experts has identified factors that, although important in explaining burnout, have been poorly studied or even forgotten. Our results suggest that further study into factors such as a lack of recognition of part of the tasks that nurses perform, feminine stereotype or excessive bureaucracy is

    Although subclinical adrenal insufficiency has been documented in tuberculosis but it has been neglected in mainstream management of TB due to inconclusive data on its prevalence in TB. The fact that adrenal insufficiency may result not only in poor general condition of the patient but also sudden death due to adrenal crisis, makes it all the more important to address this issue seriously. In this non-randomized interventional study comprising of 100 cases of TB, our aim was to assess the adreno-cortical functions in patients with pulmonary TB (50 cases) and extra-pulmonary TB (50 cases) in an attempt to determine if there is any compromise of adrenal function. In this study, 100 cases of active TB were investigated for adrenal insufficiency by measuring morning fasting basal serum cortisol levels, followed by low dose ACTH stimulation test using 1μg synacthen (synthetic ACTH analog). The post-stimulation serum cortisol levels were estimated. Basal serum cortisol levelsstimulation test serum cortisol level incrementstimulation serum cortisol levelsstimulation test, cortisol response was subnormal in 76% cases. Incidence of adrenal insufficiency in pulmonary TB (74%) and extra-pulmonary TB (78%) were comparable. The number of females having adrenal insufficiency in both the groups was higher than the males (67.3% males and 83.3% females) but the difference was statistically significant only in extra-pulmonary TB group (p=0.011). On analysing the data, the sensitivity of basal serum cortisol level estimation in diagnosing adrenal insufficiency was observed to be 21.05% and its specificity was 100%. Positive predictive value was 100% and negative predictive value was 28.57%. Diagnostic accuracy of basal serum cortisol level estimation was observed to be 40%. The incidence of subclinical adrenal insufficiency in TB cases attending chest department at a tertiary care hospital was significantly high but comparable in both pulmonary and extra-pulmonary type of TB

    Adolescents’ peer experiences may have significant associations with biological stress-response systems, adding to or reducing allostatic load. This study examined relational victimization as a unique contributor to reactive hypothalamic–pituitary–adrenal (HPA) axis responses as well as friendship quality and behavior as factors that may promote HPA recovery following a stressor. A total of 62 adolescents (ages 12–16; 73% female) presenting with a wide range of life stressors and adjustment difficulties completed survey measures of peer victimization and friendship quality. Cortisol samples were collected before and after a lab-based interpersonally themed social stressor task to provide measures of HPA baseline, reactivity, and recovery. Following the stressor task, adolescents discussed their performance with a close friend; observational coding yielded measures of friends’ responsiveness. Adolescents also reported positive and negative friendship qualities. Results suggested that higher levels of adolescents’ relational victimization were associated with blunted cortisol reactivity, even after controlling for physical forms of victimization and other known predictors of HPA functioning (i.e., life stress or depressive symptoms). Friendship qualities (i.e., low negative qualities) and specific friendship behaviors (i.e., high levels of responsiveness) contributed to greater HPA regulation; however, consistent with theories of rumination, high friend responsiveness in the context of high levels of positive friendship quality contributed to less cortisol recovery. Findings extend prior work on the importance of relational victimization and dyadic peer relations as unique and salient correlates of adaptation in adolescence. PMID:25047287

    Stigma defined as "undesired differentness" (Goffman, 1963) and subtyped as "experienced" or "enacted," "anticipated," and "internalized" has been documented for patients with diverse chronic diseases. However, no systematic data exist on the association of stigma with somatic intersexuality. The current report concerns women with classical congenital adrenal hyperplasia (CAH), the most prevalent intersex syndrome, and provides descriptive data on CAH-related stigma as experienced in the general social environment (excluding medical settings and romantic/sexual partners) during childhood, adolescence, and adulthood. A total of 62 adult women with classical CAH [41 with the salt-wasting (SW) variant and 21 with the simple-virilizing (SV) variant] underwent a qualitative retrospective interview, which focused on the impact of CAH and its medical treatment on many aspects of women's lives. Deductive content analysis was performed on the transcribed texts. The women's accounts of CAH-related stigma were identified and excerpted as vignettes, and the vignettes categorized according to social context, stigma type, and the associated features of the CAH condition. Nearly two-thirds of women with either variant of CAH provided stigma vignettes. The vignettes included all three stigma types, and most involved some somatic or behavioral feature related to sex or gender. Stigma situations were reported for all ages and all social contexts of everyday life: family, peers, colleagues at work, strangers, and the media. We conclude that there is a need for systematic documentation of stigma in intersexuality as a basis for the development of improved approaches to prevention and intervention.

    In patients with rheumatoid arthritis (RA) and systemic lupus erythematosus (SLE), low levels of adrenal steroids have been repeatedly demonstrated, but the site of alteration has not been exactly described because measurements of serum pregnenolone and 17-hydroxypregnenolone (17OHPreg) together with other adrenal steroids have never been performed. We measured serum levels of adrenal hormones such as pregnenolone, 17OHPreg, dehydroepiandrosterone (DHEA), DHEA sulfate (DHEAS), progesterone (P), 17-hydroxyprogesterone (17OHP), androstenedione (ASD), and cortisol in 24 healthy controls, 24 patients with RA, and 24 patients with SLE. Serum levels of pregnenolone were similar in RA and SLE patients as compared to healthy controls irrespective of prior prednisolone therapy. In all RA and SLE patients (including those with prior prednisolone treatment), serum levels of all measured hormones except pregnenolone were significantly lower as compared to controls. In RA patients without prior prednisolone treatment, serum levels of 17OHPreg, DHEA, cortisol, and ASD were similar to controls, and serum levels of P, 17OHP, and DHEAS were significantly lower as compared to controls. In SLE patients without prior prednisolone treatment, serum levels of 17OHPreg and cortisol were similar, and serum levels of P, 17OHP, ASD, DHEA, and DHEAS were significantly lower as compared to controls. The primary hormone of the adrenal steroid cascade, pregnenolone, is almost normal in RA and SLE irrespective of corticosteroid treatment. In patients with RA, we believe that there is a near normal P450scc reaction and a normal double step P450c17 reaction. In SLE patients, the P450scc reaction also seems normal but the second step of the P450c17 reaction seems to be inhibited. In both diseases, cortisol levels remain relatively stable at the expense of other adrenal hormones. This study revealed distinct changes of steroid pathways that are related to the disease entities.

  2. Smooth muscle LDL receptor-related protein-1 deletion induces aortic insufficiency and promotes vascular cardiomyopathy in mice.

    Full Text Available Valvular disease is common in patients with Marfan syndrome and can lead to cardiomyopathy. However, some patients develop cardiomyopathy in the absence of hemodynamically significant valve dysfunction, suggesting alternative mechanisms of disease progression. Disruption of LDL receptor-related protein-1 (Lrp1 in smooth muscle cells has been shown to cause vascular pathologies similar to Marfan syndrome, with activation of smooth muscle cells, vascular dysfunction and aortic aneurysms. This study used echocardiography and blood pressure monitoring in mouse models to determine whether inactivation of Lrp1 in vascular smooth muscle leads to cardiomyopathy, and if so, whether the mechanism is a consequence of valvular disease. Hemodynamic changes during treatment with captopril were also assessed. Dilation of aortic roots was observed in young Lrp1-knockout mice and progressed as they aged, whereas no significant aortic dilation was detected in wild type littermates. Diastolic blood pressure was lower and pulse pressure higher in Lrp1-knockout mice, which was normalized by treatment with captopril. Aortic dilation was followed by development of aortic insufficiency and subsequent dilated cardiomyopathy due to valvular disease. Thus, smooth muscle cell Lrp1 deficiency results in aortic dilation and insufficiency that causes secondary cardiomyopathy that can be improved by captopril. These findings provide novel insights into mechanisms of cardiomyopathy associated with vascular activation and offer a new model of valvular cardiomyopathy.

    DNA methylation plays an integral role in development and aging through epigenetic regulation of genome function. DNA methyltransferase 1 (Dnmt1) is the most prevalent DNA methyltransferase that maintains genomic methylation stability. To further elucidate the function of Dnmt1 in aging and age-related diseases, we exploited the Dnmt1+/- mouse model to investigate how Dnmt1 haploinsufficiency impacts the aging process by assessing the changes of several major aging phenotypes. We confirmed that Dnmt1 haploinsufficiency indeed decreases DNA methylation as a result of reduced Dnmt1 expression. To assess the effect of Dnmt1 haploinsufficiency on general body composition, we performed dual-energy X-ray absorptiometry analysis and showed that reduced Dnmt1 activity decreased bone mineral density and body weight, but with no significant impact on mortality or body fat content. Using behavioral tests, we demonstrated that Dnmt1 haploinsufficiency impairs learning and memory functions in an age-dependent manner. Taken together, our findings point to the interesting likelihood that reduced genomic methylation activity adversely affects the healthy aging process without altering survival and mortality. Our studies demonstrated that cognitive functions of the central nervous system are modulated by Dnmt1 activity and genomic methylation, highlighting the significance of the original epigenetic hypothesis underlying memory coding and function.

    Full Text Available Bilateral adrenal hemorrhage (BAH is a rare complication typically seen in critically ill patients, which can lead to acute adrenal insufficiency and death unless it is recognized promptly and treated appropriately. We describe the case of a 64-year-old man with polycythemia vera found to be unresponsive with fever, hypotension, tachycardia, and hypoglycemia. Electrocardiogram showed ST-elevation with elevated troponin, hemoglobin, prothrombin time, and partial thromboplastin time. He required aggressive ventilator and vasopressor support. Despite primary coronary intervention, he remained hypotensive. Random cortisol level was low. He received stress dose hydrocortisone with immediate hemodynamic stability. BAH was highly suspected and was confirmed by non-contrast abdominal computed tomography. Prompt recognition and timely initiated treatment remain crucial to impact the mortality associated with acute adrenal insufficiency.

    Serum levels of dehydroepiandrosterone (DHEA) and DHEA sulphate (DHEAS) are low in chronic inflammatory diseases, although the reasons are unexplained. Furthermore, the behaviour of serum levels of these hormones during an acute inflammatory stressful disease state is not well known. In this study in patients with an acute inflammatory stressful disease state (13 patients undergoing cardiothoracic surgery) and patients with chronic inflammation (61 patients with inflammatory bowel diseases (IBD)) vs. 120 controls, we aimed to investigate adrenal hormone shifts looking at serum levels of DHEA in relation to other adrenal hormones. Furthermore, we tested the predictive role of serum tumour necrosis factor (TNF) and interleukin-6 (IL-6) for a change of serum levels of DHEA in relation to other adrenal hormones. The molar ratio of serum levels of DHEA/androstenedione (ASD) was increased in patients with an acute inflammatory stressful disease state and was decreased in patients with chronic inflammation. The molar ratio of serum levels of DHEAS/DHEA was reduced during an acute inflammatory stressful disease state and was increased in patients with chronic inflammation. A multiple linear regression analysis revealed that elevated serum levels of TNF were associated with a high ratio of serum levels of DHEA/ASD in all groups (for IL-6 in patients with an acute inflammatory stressful disease state only), and, similarly, elevated serum levels of TNF were associated with a high ratio of serum levels of DHEAS/DHEA only in IBD (for IL-6 only in healthy subjects). This study indicates that changes of serum levels of DHEA in relation to serum levels of other adrenal hormones are completely different in patients with an acute inflammatory stressful disease state compared with patients with chronic inflammation. The decrease of serum levels of DHEAS and DHEA is typical for chronic inflammation and TNF and IL-6 play a predictive role for these changes.

    Primary and secondary adrenal insufficiency are underrecognized conditions among emergency department patients, affecting an estimated 10% to 20% of critically ill patients. The signs and symptoms of cortisol deficit can be nonspecific and wide-ranging, and identification and swift treatment with stress-dosing of hydrocortisone is vital to avoid life-threatening adrenal crisis. Laboratory evaluation focuses on identification of electrolyte abnormalities typical of adrenal insufficiency, and while additional testing may depend on the type and severity of symptoms, it should not delay corticosteroid replacement. This issue provides recommendations on effective management of patients presenting with adrenal insufficiency, with particular attention to the management of critically ill and septic patients, pregnant patients, and children.

  10. Relative contributions of pituitary-adrenal hormones to the ontogeny of behavioral inhibition in the rat.

    1995-04-01

    Recent investigations revealed that adrenalectomized (ADX) rat pups exhibit deficits in behavioral inhibition. Furthermore, administration of exogenous corticosterone (CORT) restores behavioral inhibition in ADX pups. Although these studies suggest that CORT has an important role in the development of behavioral inhibition, the relative behavioral effects of elevated pituitary hormone secretion induced by ADX are not known. Therefore, experiments were conducted to assess the potential behavioral effects of elevated adrenocorticotropin (ACTH) secretion induced by ADX and to further evaluate the contribution of endogenous CORT to the development of behavioral inhibition. In Experiment 1., we verified that 10-day-old ADX rats exhibit high levels of plasma ACTH throughout the preweaning period associated with the development of behavioral inhibition. In Experiment 2, 10-day-old pups were hypophysectomized (HYPOX) and ADX and were compared behaviorally to sham-operated controls on day 14. When tested in the presence of an anesthetized unfamiliar adult male rat, HYPOX + ADX pups exhibited low levels of freezing accompanied by ultrasonic vocalizations. These pups also had reduced concentrations of plasma ACTH and CORT. In Experiment 3, 10-day-old pups were HYPOX and tested for behavioral inhibition on day 14. In comparison to sham-operated controls, HYPOX rats exhibited significantly lower levels of freezing and had reduced plasma concentrations of ACTH and CORT. Results demonstrate clearly that deficits in freezing occur even in the presence of low plasma ACTH concentrations. Therefore, elevated secretion of pituitary hormones is not a major factor that contributes to the ADX-induced deficits in behavioral inhibition.(ABSTRACT TRUNCATED AT 250 WORDS)

    The adrenal hemorrhage is a relatively rare event in newborns but must be considered in the presence of a persistent unexplained jaundice, especially in presence of predisposing factors. Serial ultrasonography is the modality of choice for initial diagnosis and follow-up of neonatal adrenal hemorrhage. We report two cases of neonatal adrenal hemorrhage presenting with persistent jaundice. The causes of the neonatal adrenal hemorrhages were a difficult vaginal delivery in macrosomic infant and a neonatal infection.

    An emerging branch of research is examining the linkage between Vitamin D and nonskeletal disorders, including endocrine diseases. In this regard, a still little studied aspect concerns the involvement of vitamin D in adrenal gland disorders. Adrenal gland disorders, which might be theoretically affected by vitamin D unbalance, include adrenal insufficiency, Cushing's syndrome, adrenocortical tumors and hyperaldosteronism. In this review, we provide an updated document, which tries to collect and discuss the limited evidence to be found in the literature about the relationship between vitamin D and adrenal disorders. We conclude that there is insufficient evidence proving a causal relationship between vitamin D levels and adrenal disorders. Evidence coming from cross-sectional clinical studies can hardly clarify what comes first between vitamin D unbalance and adrenal disease. On the other hand, longitudinal studies monitoring the levels of vitamin D in patients with adrenal disorders or, conversely, the possible development of adrenal pathologies in subjects affected by impaired vitamin D levels would be able to elucidate this still unclear issue.

    Full Text Available Vitamin D and calcium insufficiencies are risk factors for multiple chronic diseases. Data from 46 recent studies from Europe, North America, South-East Asia and the South Pacific area clearly indicate that a low vitamin D status and inadequate calcium nutrition are highly prevalent in the general population (30–80%, affecting both genders. The extent of insufficiencies is particularly high in older populations, and in some geographical areas, also in children and in young women of child-bearing age, in ethnic minorities and immigrants, as well as in people of low socio-economic status. Enrichment of cereal grain products with vitamin D and calcium would be a viable approach to increase consumption and improve health outcomes in the general population worldwide.

    The pathologies of the adrenal cortex -adrenal insufficiency and Cushing syndrome- have their origin on the deficit or hypersecretion of some of the hormones that are secreted by the adrenal cortex, which is divided in three zones anatomically defined: the external zone, also called the zona glomerulosa, which is the main production site of aldosterone and mineralocorticoids; the internal zone, or zona reticularis, that produces androgens; and the external zone, or zone 1 orticotrop, which is responsible for producing glucocorticoids. In this work, a quantitative analysis of those hormones and their pathologic trigger was made; the quantification was made in the laboratory by means of highly sensitive and specific techniques, in this case, the radioimmunoassay, in which a radioisotope I-125 is used. This technique is based on the biochemical bond-type reaction, because it requires of a substance called the linker, which bonds to another called ligand. This reaction is also known as antigen-antibody (Ag-Ab), where the results of the reaction will depend on the quantity of antigen in the sample and on its affinity for the antibody. In this work, a 56 patients (of which 13 were men and 43 women) study was made. The cortisol, the ACTH, the androsterone and the DHEA values were very elevated in the majority of the cases corresponding to women, predominating cortisol; while in men, a notorious elevation of the 17 {alpha}-OH-PRG and of the DHEA-SO{sub 4} was observed. Based on that, we can conclude that 51 of them did not have mayor complications, because they just went to the laboratory once, while the remaining 5 had a medical monitoring, and they visited the laboratory more than one occasion, tell about a difficulty on their improvement. According to the results, an approximate relation of 8:2 women:men, respectively, becomes clear to the hormonal pathologies of the adrenal cortex. (Author)

Although often asymptomatic, life-threatening adrenal insufficiency may develop in the bilateral adrenal gland hemorrhage. Isolated adrenal injuries are very rare. They are often associated with other organ injuries. The mortality rates of patients range from 7% to 32%. In this report, we present the computed tomography and magnetic resonance imaging findings of unilateral adrenal hemorrhages in two patients with a history of fall from a height.

    Full Text Available Background: In recent times, there are reports of adrenal dysfunction in whole spectrum of liver disease. Adrenal insufficiency (AI has been shown to correlate with progression of liver disease. Hence this study was conducted to assess adrenal function in subjects with acute liver disease (ALD, chronic liver disease (CLD and post liver transplantation (LT. Material and Methods: This study included 25 healthy controls, 25 patients of ALD, 20 subjects of CLD with Child-Pugh stage A (CLD-1 and 30 with Child-Pugh stage B or C (CLD-2, and 10 subjects with LT. All subjects were assessed clinically, biochemically and for adrenal functions. Results: AI was present in 9 (34.6% patients with ALD, 20 (40% patients with CLD and 4 (40% in subjects with LT. AI was more common in CLD-2 (18 patients - 60% than CLD-1 (2 patients - 10%. All patients with chronic liver disease had significantly lower basal cortisol (8.8±4.8, P=0.01, stimulated cortisol (18.2±6.3, P <0.00001 and incremental cortisol (9.4±4.6, P <0.00001 as compared to controls. There was increase in percentage of subjects with adrenal dysfunction with progression of liver disease as assessed by Child-Pugh staging. AI was predicted by lower levels of serum protein, serum albumin, total cholesterol and HDL cholesterol and higher levels of serum bilirubin and INR. Adrenal functions showed recovery following liver transplantation. Conclusions: AI forms important part of spectrum of acute and chronic liver disease. Deterioration of synthetic functions of liver disease predicts presence of AI, and these patients should be evaluated for adrenal dysfunction periodically.

    1977-01-01

    S-Adenosylmethionine metabolism and its relation to the synthesis and accumulation of polyamines was studied in rat liver under various nutritional conditions, in adrenalectomized or partially hepatectomized animals and after treatment with cortisol, thioacetamide or methylglyoxal bis(guanylhydrazone) {1,1′-[(methylethanediylidine)dinitrilo]diguanidine}. Starvation for 2 days only slightly affected S-adenosylmethionine metabolism. The ratio of spermidine/spermine decreased markedly, but the concentration of total polyamines did not change significantly. The activity of S-adenosylmethionine decarboxylase initially decreased and then increased during prolonged starvation. This increase was dependent on intact adrenals. Re-feeding of starved animals caused a rapid but transient stimulation of polyamine synthesis and also increased the concentrations of S-adenosylmethionine and S-adenosylhomocysteine. Similarly, cortisol treatment enhanced the synthesis of polyamines, S-adenosylmethionine and S-adenosylhomocysteine. Feeding with a methionine-deficient diet for 7–14 days profoundly increased the concentration of spermidine, whereas the concentrations of total polyamines and of S-adenosylmethionine showed no significant changes. The results show that nutritional state and adrenal function play a significant role in the regulation of hepatic metabolism of S-adenosylmethionine and polyamines. They further indicate that under a variety of physiological and experimental conditions the concentrations of S-adenosylmethionine and of total polyamines remain fairly constant and that changes in polyamine metabolism are not primarily connected with changes in the accumulation of S-adenosylmethionine or S-adenosylhomocysteine.

  7. Stress responsiveness of the hypothalamic-pituitary-adrenal axis: age-related features of the vasopressinergic regulation

    2013-03-01

    Full Text Available The hypothalamic-pituitary-adrenal (HPA axis plays a key role in adaptation to environmental stresses. Parvicellular neurons of the hypothalamic paraventricular nucleus secrete corticotrophin releasing hormone (CRH and arginine vasopressin (AVP into pituitary portal system; CRH and AVP stimulate ACTH release through specific G protein-coupled membrane receptors on pituitary corticotrophs, CRH1 for CRH and V1b for AVP; the adrenal gland cortex secretes glucocorticoids in response ACTH. The glucocorticoids activate specific receptors in brain and peripheral tissues thereby triggering the necessary metabolic, immune, neuromodulatory and behavioral changes to resist stress. While importance of CRH, as a key hypothalamic factor of HPA axis regulation in basal and stress conditions in most species, is generally recognized, role of AVP remains to be clarified. This review focuses on the role of AVP in the regulation of stress responsiveness of the HPA axis with emphasis on the effects of aging on vasopressinergic regulation of HPA axis stress responsiveness. Under most of the known stressors, AVP is necessary for acute ACTH secretion but in a context-specific manner. The current data on the AVP role in regulation of HPA responsiveness to chronic stress in adulthood are rather contradictory. The importance of the vasopressinergic regulation of the HPA stress responsiveness is greatest during fetal development, in neonatal period, and in the lactating adult. Aging associated with increased variability in several parameters of HPA function including basal state, responsiveness to stressors, and special testing. Reports on the possible role of the AVP/V1b receptor system in the increase of HPA axis hyperactivity with aging are contradictory and requires further research. Many contradictory results may be due to age and species differences in the HPA function of rodents and primates.

    Adrenal schwannoma is an extremely uncommon cause of incidentaloma. It originates from neural sheath Schwann cells of the adrenal gland. We report the case of a left adrenal schwannoma incidentally discovered in a 32-year-old woman during examination of bloated feeling and stomach ache. The patient was incidentally found to have a left adrenal mass of 9 cm on abdominal ultrasonography. Computed tomography (CT) of the abdomen and [(18)F] fluorodeoxyglucose positron emission tomography (PET) were also performed. Metabolic evaluation was unremarkable. Due to the large size of the tumor, left adrenalectomy was performed. The postoperative course was uneventful. Histological examination established the diagnosis of schwannoma. This diagnosis was supported by immunohistochemistry of S-100 and vimentin positivity. In conclusion, adrenal schwannoma is an extremely rare entity and can grow considerably in size. The present case report emphasizes that clinicians should be aware of the possibility of retroperitoneal schwannoma. Total excision of benign schwannoma is associated with a favorable outcome. To our knowledge, there are case reports of schwannoma with CT and magnetic resonance imaging findings in the literature, although this is the first schwannoma case with PET-CT imaging.

    The prognosis of patients with a subchondral insufficiency fracture remains unclear. The purpose of this study was to investigate the correlation between locations of bone marrow edema (BME) lesions and clinical outcome in patients with a subchondral insufficiency fracture of the hip. We retrospectively reviewed 15 consecutive hips in 14 patients who were diagnosed with subchondral insufficiency fracture of the hip at our institution between April 2013 and September 2014. This study included five males (six hips) and nine females (nine hips), ranging from 36 to 83 years of age (mean age: 66 years). The mean duration from the onset of hip pain to MRI examination was 1.8 months (range 0.5-5 months). Both clinical and imaging findings were investigated. Based on the findings of MR images, BME lesion in the femoral head alone was observed in six patients (six hips), BME lesion in the acetabulum alone was observed in one patient (two hips) and BME lesions in both the femoral head and acetabulum were observed in seven patients (seven hips). 3 of 15 hips resulted in rapidly destructive arthrosis and their BME lesions were observed in both the femoral head and acetabulum. 8 of 15 hips successfully healed by conservative treatment and BME lesions in 7 of these 8 hips were observed in only the femoral head or acetabulum. The results of this study indicate that the locations of BME lesions (femoral side alone, acetabular side alone or both) may be related to the clinical outcome in patients with a subchondral insufficiency fracture of the hip. Patients with subchondral insufficiency fracture of the hip in whom BME lesions were observed in both the femoral head and acetabulum may have a higher risk to need to undergo total hip arthroplasty.

    It is suggested, that a relative placental insufficiency in late pregnancy is one of the releasing factors of childbirth. Under this assumption 1027 deliveries in term pregnancy (266th-294th day of pregnancy) were inquired on the interrelationship between the ratio brith-weight: placental-weight and the duration of pregnancy. The average birth-weight increases slighly but significantly with the duration of pregnancy just as the average placental-weight. The average ratio birth-weight: placental-weight decreases significantly: The more unfavorable the ratio birth-weight: placental-weight is, the shorter remains the fetus in utero. This underlines the assumption of a relative placental insufficiency as one of the releasing factors of childbirth.

    In patients with rheumatoid arthritis (RA), long-term therapy with anti-tumor necrosis factor (TNF) antibodies sensitizes the pituitary gland and improves adrenal androgen secretion in prednisolone-naïve patients. However, whether this is similar in psoriatic arthritis (PsA) is not known. The aim of this study was to assess the effect of 12 weeks of etanercept treatment upon the function of the HPA axis in patients with PsA. Eleven prednisolone-naïve patients (mean age 47.3+/-8.9 years) with PsA were included. We measured serum levels of adrenocorticotropic hormone (ACTH), 17-hydroxyprogesterone (17OHP), cortisol, and androstenedione (ASD), at baseline and at 4 and 12 weeks after initiation of anti-TNF therapy (etanercept, 50 mg every week as a single dose by sc. injection). Clinical improvement was assessed using the Disease Activity Score-28 (DAS-28). Mean levels of serum ACTH, serum cortisol, serum 17OHP and serum ASD did not markedly change during 12 weeks of etanercept treatment. Similarly, the ratio of serum cortisol divided by serum ACTH did not change during 12 weeks of anti-TNF treatment. However, an increase of serum cortisol relative to serum 17OHP or ASD was related to clinical improvement. This indicates that improvement was linked to higher serum cortisol levels relative to others adrenal hormones. This is the first study to demonstrate baseline serum levels and the course of HPA axis-related hormones in patients with PsA. An increase of serum cortisol relative to others adrenocortical hormones (i.e., androstenedione and ACTH) was accompanied by clinical improvement.

    Adrenal dysfunction may represent critical illness-related corticosteroid insufficiency (CIRCI), as evidenced by a diminished cortisol response to exogenous adrenocorticotropic hormone (ACTH), but this concept and its clinical significance remain highly controversial. We studied the adrenal response to exogenous ACTH as a function of the endogenous cortisol-to-ACTH ratio, a measure of adrenal sensitivity, and of clinical variables, during critical illness and recovery from the acute phase. We prospectively included 59 consecutive septic and nonseptic patients in the intensive care unit with treatment-insensitive hypotension in whom CIRCI was suspected; patients having received etomidate and prolonged corticosteroids were excluded. An ACTH test (250 μg) was performed, followed by a second test after ≥7 days in acute-phase survivors. Serum total and free cortisol, ACTH, and clinical variables were assessed. Patients were divided according to responses (delta, Δ) of cortisol to ACTH at the first and second tests. Patients with low (endogenous ACTH predicts a low increase of cortisol to exogenous ACTH, suggesting adrenal dysfunction, irrespective of the stage of disease. The data further suggest a role of disease severity and culture-positive sepsis.

    The condition of isotopic methods to the functional and morphological exploration of the adrenal glands is shown, with emphasis on the fact that althought the cortico-adrenal responds to these methods the same does not apply to the medullo-adrenal, which expresses its morphological changes by producing deformations on the cortical image. Funtional tests, mainly directed at the cortico-adrenal, are described first: study of exchangeable sodium and potassium; determination of the plasma concentration and metabolic clearance of some steroid hormones (cortisol, corticosterone, aldosterone); evaluation of the renin activity. These tests are based on competitive analysis and radioimmunological methods. Morphological tests are examined next. Adrenal scintigraphy uses a simple technique (intraveinous administration of 131 I 19-iodocholesterol with no special preliminary preparation) which gives good images and is only limited now by the need to avoid over exposure of the gonads to ionising radiations [fr

    Primary adrenal insufficiency is an endocrine disorder characterized by cortisol and aldosterone deficiency caused by destruction of the adrenal cortex. Adrenal crisis is a medical emergency with acute symptoms: nausea, vomiting, abdominal pain, fever, hypoglycemia, seizures, hypovolemic shock, and cardiovascular failure. It occurs in patients with chronic adrenal insufficiency who are exposed to additional stress, such as infection, trauma, or surgical procedures. Dental infection is a possible cause of adrenal crisis in patients with chronic adrenal insufficiency, so pediatric endocrinologists and pediatric dentists should be aware of this risk. The purpose of this report was to present a 6-year-old patient in whom Addison disease was diagnosed through adrenal crisis provoked by dental infection. The patient was treated with intravenous rehydration, intravenous hydrocortisone and antibiotics, and extraction of the infected primary tooth. Multidisciplinary approach and collaboration between the pediatric endocrinologist and the pediatric dentist are necessary to enable adequate medical and dental treatment in children with primary adrenal insufficiency.

    To prove the feasibility of using Hounsfield attenuation values at MDCT to detect bone bruises related to sacral insufficiency fractures. Twenty-two patients with acute sacrum trauma and no fracture findings at MDCT were included in our prospective study. Two observers independently reviewed CTs regarding visual signs of bone bruises in 132 defined regions of the sacral alae. Interobserver agreement was tested by {kappa} statistics. Subsequently, HU values were obtained in the same regions, and attenuation differences between the two sides were calculated. Validity and reliability were assessed by intraclass correlation coefficient and Bland-Altman analysis. HU differences were subjected to ROC curve analysis to determine sensitivity, specificity, PPV and NPV. MRI served as standard reference. MRI revealed 19 regions with bone bruises and associated sacral insufficiency fractures. HU measurements demonstrated good validity and reliability (r = 0.989). ROC curve analysis exhibited an ideal cutoff value of 35.7 HU density difference between affected and non-affected regions. Visual evaluation revealed moderate agreement ({kappa} = 0.48); diagnostic accuracy was inferior to objective evaluation. Assessment of differences in bone marrow density by HU measurements is an objective and reliable tool for detection of bone bruises associated with occult sacral insufficiency fractures. (orig.)

    Congenital adrenal hyperplasia (CAH) is an autossomic recessive disorder caused by impaired steroidogenesis. Patients with CAH may present adrenal insufficiency with or without salt-wasting, as well as various degrees of virilization and fertility impairment, carrying a high incidence of testicular adrenal rest tumors and increased incidence of adrenal tumors. The diagnosis of CAH is made based on the adrenocortical profile hormonal evaluation and genotyping, in selected cases. Follow-up is mainly based on hormonal and clinical evaluation. Utility of imaging in this clinical setting may be helpful for the diagnosis, management, and follow-up of the patients, although recommendations according to most guidelines are weak when present. Thus, the authors aimed to conduct a narrative synthesis of how imaging can help in the management of patients with CAH, especially focused on genitography, ultrasonography, computed tomography, and magnetic resonance imaging.

    Sex differences in glucocorticoid production are associated with increased responsiveness of the adrenal gland in females. However, the adrenal-intrinsic mechanisms that establish sexual dimorphic function remain ill defined. Glucocorticoid production is gated at the molecular level by the circadian clock, which may contribute to sexual dimorphic adrenal function. Here we examine sex differences in the adrenal gland using an optical reporter of circadian clock function. Adrenal glands were cultured from male and female Period2::Luciferase (PER2::LUC) mice to assess clock function in vitro in real time. We confirm that there is a pronounced sex difference in the intrinsic capacity to sustain PER2::LUC rhythms in vitro, with higher amplitude rhythms in adrenal glands collected from males than from females. Changes in adrenal PER2::LUC rhythms over the reproductive life span implicate T as an important factor in driving sex differences in adrenal clock function. By directly manipulating hormone levels in adult mice in vivo, we demonstrate that T increases the amplitude of PER2::LUC rhythms in adrenal glands of both male and female mice. In contrast, we find little evidence that ovarian hormones modify adrenal clock function. Lastly, we find that T in vitro can increase the amplitude of PER2::LUC rhythms in male adrenals but not female adrenals, which suggests the existence of sex differences in the mechanisms of T action in vivo. Collectively these results reveal that activational effects of T alter circadian timekeeping in the adrenal gland, which may have implications for sex differences in stress reactivity and stress-related disorders.

    Hormones produced by the adrenal glands and adipose tissues have important roles in normal physiology and are altered in many disease states. Obesity is associated with changes in adrenal function, including increase in adrenal medullary catecholamine output, alterations of the hypothalamic-pituitary-adrenal (HPA) axis, elevations in circulating aldosterone together with changes in adipose tissue glucocorticoid metabolism, and enhanced adipocyte mineralocorticoid receptor activity. It is unknown whether these changes in adrenal endocrine function are in part responsible for the pathogenesis of obesity and related comorbidities or represent an adaptive response. In turn, adipose tissue hormones or "adipokines" have direct effects on the adrenal glands and interact with adrenal hormones at several levels. Here we review the emerging evidence supporting the existence of "cross talk" between the adrenal gland and adipose tissue, focusing on the relevance and roles of their respective hormones in health and disease states including obesity, metabolic syndrome, and primary disorders of the adrenals.

    Full Text Available Little is known about the long-term health-related quality of life (HRQL and mental health outcomes for women diagnosed with congenital adrenal hyperplasia (CAH, a disorder of sex development. Though recommendations for therapists exist, no research has empirically investigated women's experiences in therapy or their recommendations for therapy. Thus the purpose of the study was to investigate HRQL, mental health concerns of women with CAH, and patients' recommendations for therapists. A qualitative methodology, consensual qualitative research, was used to answer these questions. Eight women with CAH participated in the study. Results from their interviews revealed six domains: physical functioning, psychological functioning, interpersonal processes and relationships, healthcare experiences of women with CAH, recommendations for health care professionals, and systemic considerations. Domains were further broken down into categories with results yielding implications for both medical and mental health professionals and shedding light on issues related to normalcy, concerns both related and unrelated to CAH, sex, and gender, and highlighting effective supports and therapeutic interventions.

    Full Text Available Little is known about the long-term health-related quality of life (HRQL and mental health outcomes for women diagnosed with congenital adrenal hyperplasia (CAH, a disorder of sex development. Though recommendations for therapists exist, no research has empirically investigated women's experiences in therapy or their recommendations for therapy. Thus the purpose of the study was to investigate HRQL, mental health concerns of women with CAH, and patients' recommendations for therapists. A qualitative methodology, consensual qualitative research, was used to answer these questions. Eight women with CAH participated in the study. Results from their interviews revealed six domains: physical functioning, psychological functioning, interpersonal processes and relationships, healthcare experiences of women with CAH, recommendations for health care professionals, and systemic considerations. Domains were further broken down into categories with results yielding implications for both medical and mental health professionals and shedding light on issues related to normalcy, concerns both related and unrelated to CAH, sex, and gender, and highlighting effective supports and therapeutic interventions.

    Full Text Available Occasionally, lymphoma involves the adrenal glands; however, primary adrenal lymphoma (PAL is rare and only few cases have been reported. We report a case of a 59-year-old female with primary adrenal diffuse large B-cell lymphoma (DLBCL manifested by weakness, fatigue, anorexia, and hyper pigmentation of skin. The patient initially responded to intravenous hydrocortisone in large doses by total remission of the symptoms. An abdominal computed tomography scan showed a hypodense mass in the right subdiaphragmatic space, which was suggestive of an adrenal gland tumor with adjacent liver involvement. Additionally, a smaller lesion with similar characteristics was found in the left adrenal gland. The results obtained from adrenal gland needle biopsy confirmed the diagnosis of DLBCL. Moreover, primary laboratory findings demonstrated hyponatremia, hyperkalemia, fasting blood sugar level of 153 mg/dl, and alkaline phosphatase level of 663 U/L. The mentioned symptoms and laboratory findings were indicative of adrenal insufficiency. After about 2 months, her level of consciousness decreased and urinary and fecal incontinence occurred. Therefore, brain involvement was suspected, and magnetic resonance imaging of the brain showed heterogeneous enhancement (24.8 mm in the posterior aspect of the left temporal lobe together with patchy foci of enhancement in around the ventricular areas of the brain that showed metastatic lesions of PAL. This case should remind clinicians that PAL may be a cause of adrenal incidentaloma, especially when the patient presents with the symptoms of adrenal insufficiency.

    Single photon emission tomography (SPET) of the adrenals was compared to convential gamma camera images. Depths of 19 adrenals were assessed by both the lateral skin-upper kidney pole method and by SPET. Eleven patients with adrenal disorders were also studied. An advantage of using SPET was that the analogue transverse section image showed improvement over the conventional posterior view because the liver activity was well separated from the adrenal. Furthermore, non-adrenal tissue background was virtually eliminated and adrenal depth determination facilitated. (U.K.)

    Full Text Available Modern radiological technology has transformed the way that adrenal lesions are currently investigated. The contemporary radiologist has been catapulted to the forefront in the management of adrenal disease. With the increasing use of cross-sectional imaging, adrenal lesions are being serendipitously discovered in radiological studies undertaken for non-adrenal-related conditions – the so-called adrenal ‘incidentaloma’. This review discusses the imaging modalities available for characterising these lesions, highlighting current concepts and controversies in differentiating benign from malignant pathology. The article also provides a brief overview of the spectrum of adrenal pathology commonly encountered in the adult population.

    Full Text Available Background. Extrapontine myelinolysis (EPM has been well described in the presence of rapid correction of hyponatremia. It is seldom reported with adrenal insufficiency. We report a unique case where a patient developed EPM as a result of adrenal insufficiency where the brain MRI revealed symmetrical lesion in the basal ganglia with pallidal sparing. Case Report. A 30-year-old gentleman with panhypopituitarism developed adrenal crisis, hyponatremia, and hyponatremic encephalopathy. Seven days after the rapid correction of hyponatremia, he developed parkinsonism and neuropsychiatric symptoms. MRI showed extrapontine myelinolysis without central pontine myelinolysis. Conclusion. Extrapontine myelinolysis without central pontine myelinolysis is rare and should raise a concern of associated adrenal insufficiency in the right clinical setting. Rapid correction of hyponatremia particularly in steroid-deficient states should be avoided as it can predispose to extrapontine myelinolysis. Magnetic resonance imaging is very helpful in supporting the diagnosis of EPM.

    Ran Fu

    Full Text Available BACKGROUND: Oral administration of bacterial extracts (eg, Broncho-Vaxom (BV has been proposed to attenuate asthma through modulating Treg cells. However, the underlying mechanism has not been fully characterized. This study sought to assess the effects of oral administration of BV on GSK-3β expression and Treg cells in ovalbumin (OVA-induced asthmatic mice models. METHOD: Asthmatic mice models were established with OVA challenge and treated with oral administration of BV. Next, infiltration of inflammatory cells including eosinophil and neutrophils, mucous metaplasia, levels of Th1/Th2/Treg-typed cytokines and expression of GSK3β and Foxp3 were examined in asthmatic mice models by histological analysis, Bio-Plex and western blot, respectively. Moreover, the frequencies of Treg cells were evaluated in cultured splenocytes by flow cytometry in the presence of BV or GSK3β siRNA interference. RESULTS: We found significant decrease of infiltrated inflammatory cells in bronchoalveolar lavage fluid (BALF in asthmatic mice models after oral administration of BV. Oral administration of BV was shown to significantly suppress mucus metaplasia, Th2-typed cytokine levels and GSK3β expression while increasing Foxp3 production in asthmatic mice models. Moreover, BV significantly enhanced GSK3β-related expansion of Treg cells in cultured spleen cells in vitro. CONCLUSION: Our findings provide evidence that oral administration of BV is capable of attenuating airway inflammation in asthmatic mice models, which may be associated with GSK3β-related expansion of Treg cells.

    2013-09-01

    This special article aims to summarise the current knowledge regarding the two groups of tumours with their origin in the adrenal gland: 1) adrenocortical tumours, derived from the cortex of the adrenal gland and 2) phaeochromocytomas and paragangliomas, neuroendocrine tumours derived from nodes of neural crest derived cells symmetrically distributed at both sides of the entire spine (paragangliomas [PG]). These PGs can be functioning tumors that secrete catecholamines, which confers their typical dark colour after staining with chromium salts (chromaffin tumors). Among these, the term phaeochromocytoma (PC) is restricted to those PGs derived from the chromaffin cells in the adrenal medulla (intra-adrenal PGs), whereas the term PG is used for those sympathetic or parasympathetic ones in an extra-adrenal location. We analyse the state of the art of their pathogenic and genetic bases, as well as their clinical signs and symptoms, the tests currently available for performing their diagnosis (biochemical, hormonal, imaging and molecular studies) and management (surgery, pre- and post-surgical medical treatment), considering the current and developing strategies in chemo- and radiotherapy.

    This study compares the medium-term results of De Vega, modified De Vega, and ring annuloplasty techniques for the correction of tricuspid insufficiency and investigates the risk factors for recurrent grades 3 and 4 tricuspid insufficiency after repair. In our clinic, 93 patients with functional tricuspid insufficiency underwent surgical tricuspid repair from May 2007 through October 2010. The study was retrospective, and all the data pertaining to the patients were retrieved from hospital records. Functional capacity, recurrent tricuspid insufficiency, and risk factors aggravating the insufficiency were analyzed for each patient. In the medium term (25.4 ± 10.3 mo), the rates of grades 3 and 4 tricuspid insufficiency in the De Vega, modified De Vega, and ring annuloplasty groups were 31%, 23.1%, and 6.1%, respectively. Logistic regression analysis revealed that chronic obstructive pulmonary disease, left ventricular dysfunction (ejection fraction, tricuspid insufficiency. Medium-term survival was 90.6% for the De Vega group, 96.3% for the modified De Vega group, and 97.1% for the ring annuloplasty group. Ring annuloplasty provided the best relief from recurrent tricuspid insufficiency when compared with DeVega annuloplasty. Modified De Vega annuloplasty might be a suitable alternative to ring annuloplasty when rings are not available. PMID:23466680

    This review focuses on the occurrence, imaging and differential diagnosis of insufficiency fractures. Prevalence, the most common sites of insufficiency fractures and their clinical implications are discussed. Insufficiency fractures occur with normal stress exerted on weakened bone. Postmenopausal osteoporosis is the most common cause of insufficiency fractures. Other conditions which affect bone turnover include osteomalacia, hyperparathyroidism, chronic renal failure and high-dose glucocorticoid therapy. It is a challenge for the radiologist to detect and diagnose insufficiency fractures, and to differentiate them from other bone lesions. Radiographs are still the most widely used imaging method for identification of insufficiency fractures, but sensitivity is limited, depending on the location of the fractures. Magnetic resonance imaging (MRI) is a very sensitive tool to visualize bone marrow abnormalities associated with insufficiency fractures. Thin section, multi-detector computed tomography (MDCT) depicts subtle fracture lines allowing direct visualization of cortical and trabecular bone. Bone scintigraphy still plays a role in detecting fractures, with good sensitivity but limited specificity. The most important differential diagnosis is underlying malignant disease leading to pathologic fractures. Bone densitometry and clinical history may also be helpful in confirming the diagnosis of insufficiency fractures.

    Adrenal incidentalomas are masses incidentally discovered at X rays, ultrasound or MRI examination of the abdomen. In 100 CT scans, one can expect to find two incidentalomas on average. The article by Murat and Dupas is dealing with the strategy of biological, morphological and scintigraphic examinations to be performed in such patients, to assess whether the tumor is of a benign or a malignant nature. Zenatti et al propose a detailed exploration of the aldosterone pathways, since adrenal carcinoma may be responsible for a specific profile of the serum concentrations of mineralo-steroids, compatible with a blockade of the last step of the aldosterone synthesis. The exploration of primary hyperaldosteronism requires biological and imaging techniques. Tabarin et al summarize the main biological parameters and tests available for the diagnosis of this condition and delineate the indications of imaging techniques, associated to hormonal tests to distinguish between adenoma and bilateral adrenal hyperplasia.

    Adrenal scintillation scanning, CT and ultrasonography are compared with the conventional imaging methods. The accuracy of retroperitoneal pneumography and adrenal venography are not high, and they detected only large tumors such as Cushing's syndrome and pheochromocytoma. Scintillation scanning is highly effective for the diagnoses of primary aldosteronism and Cushing's syndrome. However, this technique does not visualize pheochromocytoma or hypopituitarism. CT is noninvasive and of high diagnostic value. It is impossible to diagnose tumors by ultrasonography unless the size is more than 3 cm. (Chiba, N.)

    significant reduction in BMI (p = 0.01) and antihypertensive requirements (p = 0.04) was observed postoperatively. A surgical approach which facilitates the conservation of functional adrenal tissue represents a suitable strategy for hypercortisolism caused by BAD. This approach avoids the necessity for lifelong steroid replacement in the majority of cases with low rates of adrenal insufficiency and recurrence.

    A stress reaction involving increased adrenal hormone release occurs when starting adrenal venous sampling (AVS). The purpose of the present study was to investigate the effect of single shot venography on adrenal hormone production during AVS. This was a prospective self-controlled study. We enrolled 54 consecutive patients (21 men, 33 women; mean age 52 ± 11 years) with primary aldosteronism who underwent AVS from May 2014 to February 2015. Under non-stimulated conditions, blood samples were obtained from a common trunk of the left adrenal vein before and after single shot venography. The initial plasma aldosterone and cortisol concentration (PAC and PCC) were compared with those measured after venography for each patient. PAC and PCC were slightly but significantly decreased between before and after venography (after log transformation 2.12 ± 0.73 vs 2.07 ± 0.72, P = 0.00066, 1.89 ± 0.52 vs 1.83 ± 0.53, P = 0.00031, respectively). During non-stimulated left AVS, adrenal hormone secretion was slightly but significantly decreased after venography, similar to the normal time-related stress reaction. Venography did not increase the adrenal hormone secretion.

While most incidentalomas represent benign disease, typically an adenoma, the possibility of malignant involvement of the adrenal gland necessitates a reliance on imaging to inform management decisions. In this article, we review the literature on adrenal gland imaging, with particular emphasis on computed tomography, magnetic resonance imaging, and photon-emission tomography, and discuss how these findings relate to clinical practice. Emerging technologies, such as contrast-enhanced ultrasonography, dual-energy computed tomography, and magnetic resonance spectroscopic imaging will also be briefly addressed.

Both, the normal CT findings of the adrenal gland and the normal variants in shape and position are described. With help of morphometry and image processing measurements of the size of the adrenal gland of 20 healthy patients were made and are listed; not only the respective normal variants but also hypo-hyperplasia are pointed out. Some examples are suitable for the illustration of pathologic conditions, such as inflammation and benign and malignant primary and secondary neoplasis. Finally, the value of adrenal gland CT is discussed with reference to the other radiologic methods. (orig.)

    Aging is characterized by disturbances in the functioning of the hypothalamic-pituitary-adrenal (HPA) axis, associated with disturbances in the adaptation processes and increase of the probability of the onset of post-stress syndrome. However, the individual features of age-related disorders stress reactivity of HPA axis have not been studied. The purpose was to study individual characteristics of the HPA axis responsiveness to acute psycho-emotional stress exposure (restraint, ASE) at different age periods on the model of the young adult and old physically healthy female rhesus monkeys that differ in their behavioral responses to stress, i.e., with depression-like and anxiety-like behavior (DAB) on the one hand and healthy standard (control) adaptive behavior (SB) on the other hand. No significant intergroup differences were observed in HPA axis responses to ASE in young animals. During aging the monkeys with SB showed reduced ACTH response to the ASE, whereas the monkeys with DAB demonstrated its increase. The old animals with DAB in response to ASE demonstrated the most pronounced HPA axis disorders, such as the highest levels of corticotrophin (ACTH), the lowest levels of dehydroepiandrosterone sulfate (DHEAS), reduced cortisol (F) levels and the highest values of the F/DHEAS molar ratio. The ratio F/DHEAS positively correlates with the malondialdehyde concentration in erythrocytes that is considered as the biomarker of oxidative stress. Thus, these data allow us to consider the old monkeys with DAB as individuals with higher vulnerability to the adverse effects of ASE. In addition, depression-like and anxiety-like behavior of aged primates under mild/moderate stress along with reduced DHEAS plasma concentration and increased values of F/DHEAS ratio can be used to identify individuals with increased vulnerability to ASE and accelerated aging.

  12. ACTH-induced caveolin-1 tyrosine phosphorylation is related to podosome assembly in Y1 adrenal cells

    International Nuclear Information System (INIS)

    Colonna, Cecilia; Podesta, Ernesto J.

    2005-01-01

    Y1 adrenocortical cells respond to ACTH with a characteristic rounding-up that facilitates cAMP signaling, critical for transport of cholesterol to the mitochondria and increase in steroid secretion. We here demonstrate that caveolin-1 participates in coupling activation of protein kinase A (PKA) to the control of cell shape. ACTH/8-Br-cAMP induced reorganization of caveolin-1-positive structures in correlation with the cellular rounding-up. Concomitant with this change, there was an increase in the phosphorylation of caveolin-1 (Tyr-14) localized at focal adhesions (FA) with reorganization of FA to rounded, ringlike structures. Colocalization with phalloidin showed that phosphocaveolin is present at the edge of actin filaments and that after ACTH stimulation F-actin dots at the cell periphery become surrounded by phosphocaveolin-1. These observations along with electron microscopy studies revealed these structures as podosomes. Podosome assembly was dependent on both PKA and tyrosine kinase activities because their formation was impaired after treatment with specific inhibitors [myristoylated PKI (mPKI) or PP2, respectively] previous to ACTH/8-Br-cAMP stimulation. These results show for the first time that ACTH induces caveolin-1 phosphorylation and podosome assembly in Y1 cells and support the view that the morphological and functional responses to PKA activation in steroidogenic cells are related to cytoskeleton dynamics

    To evaluate the efficacy of manual lymphatic drainage (MLD) in improving health-related quality of life (HRQOL), symptomatology, and physical status in patients with chronic venous insufficiency (CVI). Single-blind randomized controlled trial. Health community attendant service. Subjects with CVI (N=41) were randomly assigned to an experimental group (n=20; mean age, 54.6±11.3y) or control group (n=21; mean age, 46.8±11.1y). The experimental group completed 10 lower extremity MLD sessions over 4 weeks and 1 educational session. The control group only attended the educational session. Outcome measures were taken at baseline (t0), at the end of 4 weeks (t1), and after 2 months for follow-up (t2). HRQOL was assessed with the Chronic Venous Insufficiency Quality of Life Questionnaire-20, symptoms (fatigue, heaviness) were assessed with a visual analog scale, severity of the disease was assessed with the Venous Clinical Severity Score (VCSS) (total score, score for each item), leg volumetry was assessed with perimeters, and plantar/dorsiflexion strength and ankle range of motion (ROM) were assessed with dynamometry. A significant interaction group×time effect was found for pain on HRQOL (F2,78=3.507; P=.035; partial η2=.087), clinical severity (F2,78=5.231; P=.007; partial η2=.118), especially for venous edema (assessed with the VCSS), fatigue (F1.67,65.21=4.690; P=.012; partial η2=.107), and heaviness (F1.57,61.32=9.702; P=.001; partial η2=.199), with the experimental group improving from t0 to t1 and t0 to t2 in all of these outcomes. No effect of MLD treatment could be found for ankle muscle strength, ankle ROM, and leg volume. Short-term MLD treatment ameliorates CVI severity and related edema, symptoms, and pain HRQOL in patients with CVI. Copyright © 2015 American Congress of Rehabilitation Medicine.

    Pubertal development is marked by profound changes in stress reactivity. For example, following a brief stressor, such as foot shock, ether inhalation or restraint, prepubertal rats display a prolonged adrenocorticotrophic hormone (ACTH) and corticosterone response that takes twice as long to return to baseline compared to adults. Pubertal-related differences in the recovery of the hormonal stress response following a more protracted systemic stressor, such as an immunological challenge, have not yet been investigated. Moreover, it is unclear whether an immunological stressor leads to a differential cytokine response in animals before and after pubertal maturation. To examine these issues, we used a single injection of lipopolysaccharide (LPS; 0.1 mg/kg) to induce a hormonal stress and innate immune response and measured plasma ACTH, corticosterone, and the pro-inflammatory cytokines interleukin (IL)-1β and IL-6 in prepubertal and adult male rats 0, 2, 4, 6, 8, or 24 h after LPS exposure. In a follow-up experiment, we assessed neural activation, as indexed by FOS immunohistochemistry, in the paraventricular nucleus of the hypothalamus (PVN) in prepubertal and adult males 0, 4, 8, or 24 h after a 0.1 mg/kg injection of LPS. By contrast to the prolonged response observed in prepubertal animals following a variety of acute stressors, we found that corticosterone and IL-6 responses induced by LPS recover toward baseline faster in prepubertal compared to adult rats. Along with these different peripheral responses, we also found that LPS-induced neural activation in the PVN of prepubertal animals showed a faster return to baseline compared to adults. Together, these data indicate that prepubertal and adult animals react in distinct ways, both peripherally and centrally, to an immunological stressor. © 2011 The Authors.

    2005-04-01

    Full Text Available Abstract We report on a 14 year old boy who presented with the symptoms abdominal pain, fever and proteinuria. A hematoma in the region of the right pararenal space was diagnosed. Prothrombin time and activated partial thromboplastin time were prolonged, lupus anticoagulant and anticardiolipin antibodies were positive and serum cortisol was normal. Ten days after admission the boy suddenly suffered generalized seizures due to low serum sodium. As well, the patient developed hemolytic anemia, acute elevated liver enzymes, hematuria and increased proteinuria. At this time a second hemorrhage of the left adrenal gland was documented. Adrenal function tests revealed adrenal insufficiency. We suspected microthromboses in the adrenals and secondary bleeding and treated the boy with hydrocortisone, fludrocortisone and phenprocoumon. Conclusion Adrenal failure is a rare complication of APS in children with only five cases reported to date. As shown in our patient, this syndrome can manifest in a diverse set of simultaneously occurring symptoms.

    In the human body, the adrenal steroids collectively regulate a plethora of fundamental functions, including electrolyte and water balance, blood pressure, stress response, intermediary metabolism, inflammation, and immunity. Therefore, adrenal steroidogenesis is an important biochemistry topic for students to learn in order for them to understand health consequences caused by deficiencies of enzymes in the adrenal steroidogenic pathways. However, popular biochemistry textbooks contain insufficient information and may sometimes give students a misimpression about certain aspects of human adrenal steroidogenesis. This article highlights two neglected issues in teaching human adrenal steroidogenesis in popular biochemistry textbooks. The purpose of this article is to draw attention to these issues. © 2017 by The International Union of Biochemistry and Molecular Biology, 45(6):469-474, 2017. © 2017 The International Union of Biochemistry and Molecular Biology.

    To our knowledge, no case of remission in autoimmune Addison's disease has previously been reported. We describe a patient with primary adrenal insufficiency caused by autoimmune adrenalitis in whom partial remission was observed after 7 yr. A 39-yr-old male was referred because of extreme fatigue, weight loss, anorexia, nausea, and bouts of fever. During physical examination hyperpigmentation was seen. Laboratory tests showed a plasma cortisol of 0.02 micromol/l (08:30 h). Cortisol failed to increase during the ACTH stimulation test (0.02 to 0.03 micromol/l) and ACTH was markedly elevated (920 pmol/l). Adrenal auto-antibodies were weakly positive. A CT-scan showed no evidence of calcifications or other abnormalities of the adrenal glands. The diagnosis of autoimmune Addison's disease was made and replacement therapy with hydrocortisone and fludrocortisone was started. During the following years the dose of hydrocortisone was gradually decreased. Eventually, the patient decided to stop his medication completely. A repeated ACTH-stimulation test revealed a basal cortisol of 0.25 micromol/l and a peak cortisol of 0.30 micromol/l with a basal ACTH of 178 pmol/l. The patient did not have any complaints. Recovery of adrenal insufficiency, due to causes other than autoimmune adrenalitis, has been reported in the past. If our case of partial recovery of autoimmune adrenalitis is not unique this could have profound effects on treatment and follow-up of Addison's disease.

    To evaluate the evidence for and against androgen insufficiency as a cause of sexual and other health-related problems in women and to make recommendations regarding definition, diagnosis, and assessment of androgen deficiency states in women. Evaluation of peer-review literature and consensus conference of international experts. Multinational conference in the United States. Premenopausal and postmenopausal women with androgen deficiency. Evaluation of peer-review literature and development of consensus panel guidelines. The term "female androgen insufficiency" was defined as consisting of a pattern of clinical symptoms in the presence of decreased bioavailable T and normal estrogen status. Currently available assays were found to be lacking in sensitivity and reliability at the lower ranges, and the need for an equilibrium dialysis measure was strongly emphasized. Causes of androgen insufficiency in women were classified as ovarian, adrenal, hypothalamic-pituitary, drug-related, and idiopathic. A simplified management algorithm and clinical guidelines were proposed to assist clinicians in diagnosis and assessment. Androgen replacement is currently available in several forms, although none has been approved for treatment of sexual dysfunction or other common symptoms of female androgen insufficiency. Potential risks associated with treatment were identified, and the need for informed consent and careful monitoring was noted. Finally, the panel identified key goals and priorities for future research. A new definition of androgen insufficiency in women has been proposed along with consensus-based guidelines for clinical assessment and diagnosis. A simplified management algorithm for women with low androgen in the presence of clinical symptoms and normal estrogen status has also been proposed.

  19. Prolactin induces adrenal hypertrophy

    Full Text Available Although adrenocorticotropic hormone is generally considered to play a major role in the regulation of adrenal glucocorticoid secretion, several reports have suggested that other pituitary hormones (e.g., prolactin also play a significant role in the regulation of adrenal function. The aim of the present study was to measure the adrenocortical cell area and to determine the effects of the transition from the prepubertal to the postpubertal period on the hyperprolactinemic state induced by domperidone (4.0 mg kg-1 day-1, sc. In hyperprolactinemic adult and young rats, the adrenals were heavier, as determined at necropsy, than in the respective controls: adults (30 days: 0.16 ± 0.008 and 0.11 ± 0.007; 46 days: 0.17 ± 0.006 and 0.12 ± 0.008, and 61 days: 0.17 ± 0.008 and 0.10 ± 0.004 mg for treated and control animals, respectively; P < 0.05, and young rats (30 days: 0.19 ± 0.003 and 0.16 ± 0.007, and 60 days: 0.16 ± 0.006 and 0.13 ± 0.009 mg; P < 0.05. We selected randomly a circular area in which we counted the nuclei of adrenocortical cells. The area of zona fasciculata cells was increased in hyperprolactinemic adult and young rats compared to controls: adults: (61 days: 524.90 ± 47.85 and 244.84 ± 9.03 µm² for treated and control animals, respectively; P < 0.05, and young rats: (15 days: 462.30 ± 16.24 and 414.28 ± 18.19; 60 days: 640.51 ± 12.91 and 480.24 ± 22.79 µm²; P < 0.05. Based on these data we conclude that the increase in adrenal weight observed in the hyperprolactinemic animals may be due to prolactin-induced adrenocortical cell hypertrophy.

    Full Text Available Abstract Introduction Familial Mediterranean fever is an autosomal recessive disease that predominantly affects people of the Mediterranean coast. One of the most frequent complications of the disease is amyloidosis. This clinical entity is known as secondary (also called AA amyloidosis. Case presentation In this report, we describe the case of a 33-year-old Turkish man with familial Mediterranean fever and chronic renal insufficiency. He was admitted to our clinic with symptoms of suprarenal insufficiency. The patient died three months later as a result of cardiac arrest. Conclusion Our aim is to make a contribution to the literature by reporting a case of combined insufficiency due to the accumulation of renal and adrenal amyloid in a patient with familial Mediterranean fever, which has very rarely been described in the literature. We hope that adrenal insufficiency, which becomes fatal if not diagnosed and treated rapidly, will come to mind as easily as chronic renal failure in clinical practice.

  2. The contributions of adrenal hormones, hemodynamic factors, and the endotoxin-related stress reaction to stable prostaglandin analog-induced peripheral lymphopenia and neutrophilia.

    Stable prostaglandin analogs are known to induce lymphopenia and neutrophilia in a dose-dependent fashion after subcutaneous injection in rats. The purpose of the present investigation is to determine whether the prostaglandin-induced changes in circulating leukocytes might be secondary to hypotension with the ensuing release of adrenal hormones. The adrenal medullary catecholamine epinephrine was found to induce neutrophilia in both intact and adrenalectomized rats, and the glucocorticosteroid analog dexamethasone induced a profound lymphopenia in rats as reported by previous investigators. A stable analog of PGF2 alpha (15-S-15-methyl PGF2 alpha; M-PGF2 alpha) at the dose of 1 mg/kg induced marked systemic hypotension 1 h after injection, with lymphopenia and neutrophilia 6 h after injection. The non-prostanoid hypotensive agent captopril, at a dose of 63 mg/kg, induced a hypotension of similar magnitude and kinetics to that induced by prostaglandin. Captopril also induced lymphopenia and neutrophilia at 6 h, although the neutrophilia was of lesser magnitude than that induced by prostaglandins. The prostaglandin-induced lymphopenia was found to be mediated, at least in part, by the hypotension-induced release of adrenal hormones, as evidenced by the abrogation of lymphopenia in prostaglandin-treated adrenalectomized rats. Captopril-treated adrenalectomized rats, however, did develop a significant lymphopenia, suggesting that hypotension can result in lymphopenia even in adrenalectomized rats. The M-PGF2 alpha-induced neutrophilia in adrenalectomized rats, by comparison to captopril-induced neutrophilia in adrenalectomized rats, was greater than the neutrophilia expected as the result of hypotension alone. Indeed, the M-PGF2 alpha-induced neutrophilia in adrenalectomized rats was greater than the captopril-induced neutrophilia in sham-adrenalectomized rats. Thus, a portion of the neutrophilia induced by M-PGF2 alpha in intact rats may be mediated through adrenal

    1996-04-01

    Traumatic tricuspid insufficiency is a rare condition. The diagnosis is difficult because of the slow progression of this pathology and the presence of more clinically acute lesions. Non-penetrating chest trauma is responsible for 90% of cases. Echocardiography is the investigation of choice for assessing the mechanism of the tricuspid regurgitation and for diagnosing associated lesions. It should be performed systematically in patients with multiple trauma. The surgical indications are difficult to determine and depend on the patients' symptoms and the type of anatomical lesions. It should be undertaken before right ventricular myocardial dysfunction. Several techniques may be used from valvuloplasty to valve replacement mainly with bioprostheses in symptomatic patients.

    In around half of the patients with neuroblastoma (NBL), the primary tumor is located in one of the adrenal glands. We have previously reported on a transplantable TH-MYCN model of subcutaneous (SC) growing NBL in C57Bl/6 mice for immunological studies. In this report, we describe an orthotopic TH-MYCN transplantable model where the tumor cells were injected intra-adrenally (IA) by microsurgery. Strikingly, 9464D cells grew out much faster in IA tumors compared to the subcutis. Tumors were infiltrated by equal numbers of lymphocytes and myeloid cells. Within the myeloid cell population, however, tumor-infiltrating macrophages were more abundant in IA tumors compared to SC tumors and expressed lower levels of MHC class II, indicative of a more immunosuppressive phenotype. Using 9464D cells stably expressing firefly luciferase, enhanced IA tumor growth could be confirmed using bioluminescence. Collectively, these data show that the orthotopic IA localization of TH-MYCN cells impacts the NBL tumor microenvironment, resulting in a more stringent NBL model to study novel immunotherapeutic approaches for NBL.

    Full Text Available Abstract Background Most research concerning congenital adrenal hyperplasia (CAH and related conditions caused by primary adrenal insufficiency, such as Addison's or Cushing's disease, has focused on medical aspects rather than on patients' quality of life. Therefore, our objective was to investigate the physical, social and societal functioning of children with CAH and their parents in a Dutch population. Methods The study is descriptive and cross-sectional. Self-designed questionnaires, based on questionnaires developed in the Netherlands for different patient groups, were sent to parents of children with CAH between 0 and 18 years old. Participants were recruited through the Dutch patient group for Adrenal Disease (NVACP and six hospitals in the Netherlands. Three different questionnaires were designed for parents: for children aged 0 - 4, aged 4 - 12 and aged 12 - 18. Additionally, a fourth questionnaire was sent to adolescents with CAH aged 12 - 18. Main outcome measures were experienced burden of the condition, self-management and participation in several areas, such as school and leisure time. Results A total of 106 parents returned the questionnaire, 12 regarding pre-school children (0-4 years, 63 regarding primary school children (4-12 years, and 32 regarding secondary school children (12-18 years, combined response rate 69.7%. Also, 24 adolescents returned the questionnaire. Children and adolescents with CAH appear to be capable of self-management at a young age. Experienced burden of the condition is low, although children experience several health related problems on a daily basis. Children participate well in school and leisure time. Few children carry a crisis card or emergency injection with them. Conclusions Overall, our research shows that, according to their parents, children with CAH experience few negative effects of the condition and that they participate well in several areas such as school and leisure time.

    Of 155 patients with adrenal disorders, 120 (77%) were correctly diagnosed as negative. There were no correlations between the results of computer tomography and phlebography or between computer tomography and laboratory tests. In 31 patients (20%) a correct diagnosis was obtained and these patients were sent to surgery. Four cases (3%) were shown to be false positive. In these cases (with one exception), both the computer tomography and phlebography results had been overinterpreted. Computer tomography was shown to be a method of high sensitivity and almost as great specificity. Tumors cannot be distinguished by phlebography; only pheochromocytoma shows a characteristic alteration of vessels in arteriograms. In general, an accurate diagnosis requires positive angiography (arterio- or phlebography) results and clear evidence of elevated hormone levels. Only then is surgery indicated.

    Twenty post-mortem specimens and 93 phlebographies (56 right side, 37 left side) from 44 patients were investigated with respect to the adrenal venous anatomy. At autopsy, the venous orifices displayed in the area of adrenal drainage were injected bilaterally to identify the adrenal vein(s), the surrounding channels and the presence of interconnections. The findings were correlated with those at clinical phlebography, and the different sources of error were elicited. These were mainly found on the right side. Some guidelines are suggested in the hope that these will contribute to eliminate misconceptions.

    The incidence of stress fracture is increasing. In our younger society this is due largely to a preocupation with physical conditioning, but in our elderly population it is due to improved recognition and better methods of detection and diagnosis. Stress fracture of the elderly is an insufficiency fracture which occurs in the spine, the pelvis, the sacrum and other bones afflicted with disorders which cause osteopenia. Stress fracture is frequently misdiagnosed as a malignant lesion of bone resulting in biopsy. Scintiscanning provides the greatest frequency of detection, while computed tomography often provides the definitive diagnosis. With increased interest and experience a better insight into the disease has been achieved, and what was once thought of as a simple manifestation of mechanical stress is now known to be an orderly, complex pattern of physiological changes in bone which conform to a model by Frost. The diffuse nature of these changes can be recognized by scintigraphy, radiography and magnetic resonance imaging. 27 refs.; 8 figs

    A functional lesion in corticotrophin (ACTH)-independent Cushing's syndrome is difficult to distinguish from lesions of bilateral adrenal masses. Methods for distinguishing these lesions include adrenal venous sampling and (131)I-6β-iodomethyl-19-norcholesterol ((131)I-NP-59) scintigraphy. We present a case of a 29-year-old Han Chinese female patient with a history of hypercholesterolaemia and polycystic ovary syndrome. She presented with a 6month history of an 8kg body weight gain and gradual rounding of the face. Serial examinations revealed loss of circadian rhythm of cortisol, elevated urinary free-cortisol level and undetectable ACTH level (Cushing's syndrome presenting with bilateral adrenal masses. The clinical presentation of Cushing' syndrome includes symptoms and signs of fat redistribution and protein-wasting features.The diagnosis of patients with ACTH-independent Cushing's syndrome with bilateral adrenal masses is challenging for localisation of the lesion.Both adrenal venous sampling and (131)I-NP-59 scintigraphy are good methods to use in these patients with Cushing's syndrome presenting with bilateral adrenal masses.

    A 55-year-old Indian man presented with productive cough and a large left pleural effusion. Pleural fluid culture grew Mycobacterium tuberculosis, and he was started on antituberculosis therapy. One week later, the patient presented to hospital with drowsiness, dehydration and hypotension. He was transferred to critical care and only improved after starting hydrocortisone and stopping rifampicin. His short synACTHen test subsequently confirmed primary adrenal insufficiency, and a CT of the abdomen showed bilateral adrenal enlargement. Rifampicin is known to accelerate cortisol metabolism. We report the rare case of a rifampicin-induced adrenal crisis as a first presentation of Addison's disease in a patient with tuberculous infiltration of the adrenal glands. 2016 BMJ Publishing Group Ltd.

    To assess self-management in patients receiving glucocorticoid replacement therapy for primary or secondary adrenal failure before and 6 months after a glucocorticoid education group meeting. All patients with primary or secondary adrenal insufficiency, treated at the Department of Medicine, Division of Endocrinology, were invited by their endocrinologist to participate in a 3-h glucocorticoid education group meeting, consisting of a lecture about the disease and glucocorticoid doses adjustments in case of stress, followed by an instruction on how to inject hydrocortisone i.m. Finally, all participants could practise the i.m. injection and discuss their experience with (imminent) adrenal crises with other patients and the health care providers. Two weeks before the meeting and 6 months after the meeting, patients were asked to fill out a questionnaire about how they would act in six different conditions (e.g. febrile illness or vomiting). Of the 405 patients who were invited, 246 patients (61%) participated. At baseline the response by the participants on the questionnaire was 100% (n=246) and at follow-up 74% (n=183). At follow-up, significantly more participants (P≤0.005) gave the correct answers to how to act in different situations (e.g. self-administration of a glucocorticoid injection and phone contact in case of vomiting/diarrhoea without fever). Moreover, the use of self-management tools, such as having a 'medicine passport (travel document with information about disease and medication) (P=0.007) or SOS medallion (P=0.0007)', increased. A glucocorticoid education group meeting for patients with adrenal failure seems helpful to improve self-management and proper use of stress-related glucocorticoid dose adjustment.

    To study the morphology of the adrenal glands of patients with Addison's disease an ultrasound and a computed tomographic scan of the adrenal glands were performed in 28 patients. Thirteen patients had bilateral, asymmetric adrenal enlargement. In six of these patients, areas of necrosis and calcification were also seen. Six patients had atrophic glands with calcification and nine patients had normal/atrophic glands without calcification. After instituting appropriate treatment, computed tomography (CT) was repeated between 6 months and 3 years later in 10 of the 13 patients with adrenal enlargement. A reduction in gland size was noted in all patients and one had functional recovery. It is concluded that the appearance of the adrenal glands on CT depends not only on the nature of the underlying disease but also on the duration of the illness and the type of treatment. The results highlighted the importance of studying adrenal morphology during the initial evaluation of patients with adrenal insufficiency. 11 refs., 4 tabs., 4 figs

    Full Text Available Glucocorticoids are well known for altering bone structure and elevating fracture risk. Nevertheless, there are very few reports on pelvic ring fractures, compared to other bones, especially with a predominantly ligamentous insufficiency, resulting in a rotationally unstable pelvic girdle. We report a 39-year-old premenopausal woman suffering from an atraumatic symphysiolysis and disruption of the left sacroiliac joint. She presented with external rotational pelvic instability and immobilization. Prior to the injury, she received high-dose glucocorticoids for a tentative diagnosis of rheumatoid arthritis over two months. This diagnosis was not confirmed. Other causes leading to the unstable pelvic girdle were excluded by several laboratory and radiological examinations. Elevated basal cortisol and adrenocorticotropic hormone levels were measured and subsequent corticotropin-releasing hormone stimulation, dexamethasone suppression test, and petrosal sinus sampling verified the diagnosis of adrenocorticotropic hormone-dependent Cushing’s disease. The combination of adrenocorticotropic hormone-dependent Cushing’s disease and the additional application of exogenous glucocorticoids is the most probable cause of a rare atraumatic rotational pelvic instability in a premenopausal patient. To the authors’ knowledge, this case presents the first description of a rotationally unstable pelvic ring fracture involving a predominantly ligamentous insufficiency in the context of combined exogenous and endogenous glucocorticoid elevation.

    Aim: To analyse the computed tomography (CT) imaging features of patients with adrenal schwannoma. Materials and methods: Eight cases of adrenal schwannoma confirmed by histopathology were included in this study. All eight patients had undergone multiphase CT examinations. The features of the adrenal schwannoma in the CT images were analysed retrospectively in detail, including size, shape, margin, radiodensity, calcification, and enhancement pattern. Results: There were six male and two female patients, with a median age of 44.5 years (range, 25–52 years). Two patients complained of right flank pain, and two with left upper abdominal discomfort, while the remaining patients were diagnosed by routine ultrasound examinations. On unenhanced CT images, all cases of adrenal schwannoma were well circumscribed, rounded or oval, heterogeneous masses with cystic components, with two cases exhibiting calcification, and three cases with septa. On enhanced CT images, all cases displayed mild heterogeneous enhancement of the tumour during the arterial phase, and progressive enhancement during the portal venous phase and equilibrium phase. Conclusion: Adrenal schwannoma commonly presents as a well-defined unilateral mass with cystic degeneration, septa, and a characteristic progressive contrast-enhancement pattern on multiphase enhanced scans. - Highlights: • Adrenal schwannomas were extremely rare, and eight cases' medical data of this disease were collected in this study. • They usually presented a well-defined unilateral mass with cystic degeneration and sepations. • They manifested characteristic progressive contrast enhancement pattern on enhanced CT images.

    Subclinical hypercortisolism (HS) is diagnosed in a patient with no Cushing's syndrome manifest phenotype but with autonomic cortisol secretion. Harmful effects of chronic subtle excess of cortisol have been demonstrated, such as hypertension (AHT), type 2 diabetes mellitus (DM2) or glucose intolerance, obesity, osteoporosis, vertebral fractures and dyslipidemia. It has been suggested that subclinical hypercortisolism may itself be a vascular risk factor. In order to identify the presence of subclinical hypercortisolism and its main clinical manifestations in patients with adrenal incidentalomas treated at the endocrinology service of the 'Arnaldo Milian Castro' Clinical Surgical Hospital, a descriptive cross-sectional investigation was carried out from 2012 to 2015 The sample of intentional type was made up of 34 patients older than 18 years and diagnosis of adrenal incidentalomas. Age, sex, toxic habits, questioning results, physical examination and the necessary diagnostic investigations were analyzed. The results showed a predominance of females, over 60 years old, with toxic habits and family and personal history of hypertension and DM2. Palpitations, low back pain, asthenia and obesity with pigmentation of the skin were the most frequent clinical manifestations. Hyperglycemia, dyslipidemia, and elevated levels of cortisol occurred in the majority of patients. Imaging diagnosis showed left lesions and less than 4.0 cm and adrenal adenoma was the most frequent histopathological diagnosis. It was demonstrated that subclinical hypercortisolism is present in an important group of patients with adrenal incidentalomas, is not as asymptomatic, and is related to the presence of vascular risk factors, and other comorbidities

    The hypothalamus-pituitary-adrenal (HPA) axis is a crucial endocrine system for coping with stress. A reliable and stable marker for the basal state of that system is the cortisol awakening response (CAR). We examined the influence of variants of four relevant candidate genes; the mineralocorticoid receptor gene (MR), the glucocorticoid receptor gene (GR), the serotonin transporter gene (5-HTT) and the gene encoding the brain-derived neurotrophic factor (BDNF) on CAR and self-perceived stress in 217 healthy subjects. We found that polymorphisms of GR influenced both, the basal state of the HPA axis as well as self-perceived stress. MR only associated with self-perceived stress and 5-HTT only with CAR. BDNF did not affected any of the investigated indices. In summary, we suggest that GR variants together with the CAR and supplemented with self reports on perceived stress might be useful indicators for the basal HPA axis activity.

    Adrenal cysts are usually asymptomatic; they are usually identified occasionally during ultrasound or C.T. scans (incidentaloma). Among adrenal cysts the most common types are epithelial cysts and pseudocysts. Intracystic haemorrhage is one of the possible complications of adrenal pseudocysts. We report a case of a young woman with right superior abdominal pain, fever and acute anemia. A C.T. scan showed a 10 cm. mass between the liver and the right kidney. To be sure of the nature of this mass also M.R., urography and C.T.-guided biopsy were carried out. This latter only let us make the final diagnosis of hemorrhagic adrenal pseudocyst. Thereafter, a laparotomic right adrenalectomy was performed, with full recovery of the patient. Adrenal cysts may cause differential diagnostic problems with masses of contiguous organs like kidney, liver and gallbladder. For this reason, ultrasound and C.T. scans may not be sufficient and must be completed by M.R., urography and/or C.T.-guided biopsy. Intracystic hamorrhage, spontaneous or post-traumatic, may cause to the patient acute anemia which, as soon as the diagnosis is confirmed, indicates surgery. The operation usually is a laparotomic adrenalectomy, since the laparoscopic approach is not sufficient to control large masses with active bleeding inside.

  20. Adipose Tissue and Adrenal Glands: Novel Pathophysiological Mechanisms and Clinical Applications

    Full Text Available Hormones produced by the adrenal glands and adipose tissues have important roles in normal physiology and are altered in many disease states. Obesity is associated with changes in adrenal function, including increase in adrenal medullary catecholamine output, alterations of the hypothalamic-pituitary-adrenal (HPA axis, elevations in circulating aldosterone together with changes in adipose tissue glucocorticoid metabolism, and enhanced adipocyte mineralocorticoid receptor activity. It is unknown whether these changes in adrenal endocrine function are in part responsible for the pathogenesis of obesity and related comorbidities or represent an adaptive response. In turn, adipose tissue hormones or “adipokines” have direct effects on the adrenal glands and interact with adrenal hormones at several levels. Here we review the emerging evidence supporting the existence of “cross talk” between the adrenal gland and adipose tissue, focusing on the relevance and roles of their respective hormones in health and disease states including obesity, metabolic syndrome, and primary disorders of the adrenals.

    2006-01-01

    Polycystic ovarian disease (PCOD) is characterized by hyperandrogenemia, ovulatory dysfunction and polycystic ovaries (PCO). The increased androgen production in PCOD comes primarily from the ovaries. However, in about 40% of patients there is excessive adrenal androgen production (DHEA, DHEA-Sulfate, Androstenedione, Testosterone and Dihydrotestosterone). The contribution of the adrenal in the PCOD is suggested by the presence of adrenal androgen excess in PCO, the presence of PCO in women with enzymatic adrenal hyperplasia as well as in women with adrenal tumors. However, the cause of adrenal androgen hypersecretion is not yet fully understood but it may include endogenous hypersecretion of the zona reticularis of unclear cause, hypersecretion of cortical-androgen-stimulating hormone (CASH), stress, hyperprolactinemia, adrenal enzymatic defects etc. This short review covers the aspects of adrenal androgen hypersecretion in PCOD.

    Full Text Available Secondary osteoporosis resulting from specific clinical disorders may be potentially reversible, and thus continuous efforts to find and adequately treat the secondary causes of skeletal fragility are critical to ameliorate fracture risk and to avoid unnecessary treatment with anti-osteoporotic drugs. Among the hyperfunctional adrenal masses, Cushing's syndrome, pheochromocytoma, and primary aldosteronism are receiving particularly great attention due to their high morbidity and mortality mainly by increasing cardiovascular risk. Interestingly, there is accumulating experimental and clinical evidence that adrenal hormones may have direct detrimental effects on bone metabolism as well. Thus, the present review discusses the possibility of adrenal disorders, especially focusing on pheochromocytoma and primary aldosteronism, as secondary causes of osteoporosis.

    This study aimed at describing the magnetic resonance (MR) imaging features of the adrenal glands in beta-thalassemic patients and at investigating the relation between adrenal and hepatic siderosis. Adrenal signal intensity (SI) was retrospectively assessed on abdominal MR studies of 35 patients with beta-thalassemia major undergoing quantification of hepatic siderosis and 12 healthy controls, using T1- (120/4/90), intermediate - (120/4/20), and T2*- (120/15/20) weighted GRE sequences. Adrenal SI was graded as grade 0 (normal SI on all sequences), grade 1 (hypointensity on T2* alone), or grade 2 (hypointensity on at least T2*). Adrenal size was measured in the thalassemic patients and compared with normative data. Liver-to-muscle (L/M) SI ratios, expressing hepatic siderosis, were estimated on each sequence. Serum ferritin levels were recorded. Adrenal hypointensity (grades 1 and 2) was noted in 24/35 (68.6%) patients. L/M ratios correlated significantly with adrenal SI in all sequences. Patients with grade 1 and grade 2 adrenal SI had significantly decreased L/M ratios compared with grade 0. Serum ferritin correlated significantly with L/M values but not with adrenal SI. Adrenal size was within normal limits. Diffuse hypointensity in normal-sized adrenals is a common MR finding in beta-thalassemic patients and correlates with the degree of hepatic siderosis. (orig.)

    The development of ethanol dependence is associated with alterations in hypothalamic-pituitary-adrenal (HPA) axis and activation of type II glucocorticoid receptors (GR). These effects may contribute to withdrawal-associated anxiety, craving and relapse to drinking. The present studies examined acute and oral administration of the novel, selective and competitive GR antagonist ORG 34517 on the severity of ethanol withdrawal. Adult, male Sprague-Dawley rats were administered ethanol (4g/kg/i.g.) twice daily for 5 days followed by 2 days of withdrawal for 1, 2 or 3 consecutive cycles. Blood ethanol levels (BELs) were determined at 0930 on Day 4 of each week, while blood corticosterone levels (BCLs) were obtained at 11:00hours on the first day of each ethanol withdrawal. During early withdrawal, subjects received oral administration of ORG 345617 (60mg/kg/i.g.) or a placebo and withdrawal was monitored. Peak BELs of 225.52mg/dl were observed during the third week. Withdrawal from three cycles of the regimen produced marked behavioral abnormalities (e.g., aggression, rigidity, and hypoactivity) and significant increases in BCLs of ethanol-dependent subjects. Acute, oral administration of ORG 34517 during early withdrawal significantly reduced both the severity of ethanol withdrawal, as reflected in reduced rigidity, aggression, and hypoactivity, and elevations in BCL without producing any sedative-like effects. The present findings demonstrate that repeated ethanol exposure and withdrawal is associated with significant behavioral abnormalities and dysregulation of HPA axis activation. Further these data suggest that selective GR antagonists should be further considered as putative pharmacotherapies for treatment of ethanol dependence. Copyright © 2015 Elsevier Ireland Ltd.

    Immune and endocrine systems are basic regulatory mechanisms of organism and, including the nervous system, maintain the organism's homeostasis. The main immune system representatives are mononuclear cells, T- and B-cells and their products, in the endocrine system the main representatives are cells of the glands with inner secretion and their products. One of the most important glands for maintaining homeostasis are adrenal glands. It has been proven that either cells of the immune system, either endocrine cells can, although in trace amounts, produce mutually mediators of both systems (hormones, cytokines). Disorders in one system can lead to pathological symptoms in the other system. Also here represent adrenals an important model.

    Computed tomography (CT) and magnetic resonance (MR) imaging are first line modalities in the evaluation of patients with adrenal gland masses, and have the potential to be very accurate for the localization of adrenal gland masses in patients with diseases associated with hyperfunctioning conditions of the adrenal gland. Both CT and MR imaging allow a specific diagnosis of acute adrenal hemorrhage, adrenal myelolipoma, and adrenal cysts. CT is also helpful in the assessment of patients with Addision's disease, particularly the subacute from secondary to granulomatous diseases. Quantitative evaluation of adrenal masses on unenhanced CT scans and/or qualitative analysis on chemical-shift MR imaging have been shown to be accurate in distinguishing adrenal adenomas from non-adenomas. Attenuation of 11 HE or less on unenhanced CT scans and/or signal loss on opposed phase MR images indicate adenoma with a high specificity and acceptable sensitivity. More recently, delayed-enhanced CT has yielded higher sensitivity and specificity values in distinguishing between adrenal adenomas and non-adenomas than both unenhanced CT and chemical-shift MR imaging do. On delayed-enhanced CT scans, adrenal adenomas exhibit a greater washout of contrast material than do adrenal non-adenomas. Therefore, adrenal non-adenomas have significantly higher attenuation than adenomas on delayed-enhanced CT scans obtained at several arbitrarily chosen time points (3-60 min) after the initiation of contrast material administration.

    In this study we examined the impact of continuous-flow left ventricular assist device (CF-LVAD) support on proximal thoracic aorta dimensions. Aortic root and ascending aorta diameter were measured from serial echocardiograms before and after CF-LVAD implantation in patients with ≥6 months of support, and correlated with the development of >mild aortic valve insufficiency (AI). Of 162 patients included, mean age was 58 ± 11 years and 128 (79%) were male. Seventy-nine (63%) were destination therapy patients. Mean aortic root and ascending aorta diameters at baseline, 1 month, 6 months, 12 months and long-term follow-up (mean 2.0 ± 1.4 years) were 3.5 ± 0.4, 3.5 ± 0.3, 3.9 ± 0.3, 3.9 ± 0.2 and 4.0 ± 0.3, and 3.3 ± 0.2, 3.3 ± 0.3, 3.6 ± 0.2, 3.6 ± 0.3 and 3.6 ± 0.3 cm, respectively. Only change in aortic root diameter from 1-month to 6-month follow-up reached statistical significance (p = 0.03). Nine (6%) patients had accelerated proximal thoracic aorta expansion (>0.5 cm/year), occurring predominantly in the first 6 months after implantation. These patients were older and more likely to have hypertension and baseline proximal thoracic aorta dilation. Forty-five (28%) patients developed >mild AI at long-term follow-up, including 7 of 9 (78%) of those with accelerated proximal thoracic aorta expansion. All 7 had aortic valves that remained closed throughout the cardiac cycle, and this, along with duration of CF-LVAD support and increase in aortic root diameter, were significantly associated with developing >mild AI. CF-LVAD patients have small increases in proximal thoracic aorta dimensions that predominantly occur within the first 6 months after implantation and then stabilize. Increasing aortic root diameter was associated with AI development. Copyright © 2016 International Society for Heart and Lung Transplantation. Published by Elsevier Inc. All rights reserved.

We diagnosed her case as primary adrenocortical insufficiency (Addison's disease) by endocrinological studies. CT demonstrated dense calcification in both adrenal beds without evidence of normal glandular remnants. Calcified adrenal is not specific to tuberculosis, but some points of CT findings are useful for pathogenetic approach.

    Adrenal gland vein sampling is an interventional method to get the blood samples from the adrenal gland vein. The blood is obtained via a catheter which is selectively inserted in the adrenal gland vein. This technique is mainly used to be diagnostic for primary hyperaldosteronism. A full knowledge of the anatomy and variations of the adrenal gland vein, serious preoperative preparation and skilled catheterization manipulation are necessary for obtaining sufficient blood sample and for reducing the occurrence of complications. Providing the physicians with definite diagnostic evidence and being technically feasible, adrenal gland vein sampling should become one of the routine examinations for clarifying the cause of primary hyperaldosteronism.

    Insufficiency fracture occurs when normal or physiological stress applied to weakened bone with demineralization and decreased elastic resistance. Recently, many studies reported the development of IF after radiation therapy (RT) in gynecological cancer, prostate cancer, anal cancer and rectal cancer. The RT-induced insufficiency fracture is a common complication during the follow-up using modern imaging studies. The clinical suspicion and knowledge the characteristic imaging patterns of insufficiency fracture is essential to differentiate it from metastatic bone lesions, because it sometimes cause severe pain, and it may be confused with bone metastasis.

    2016-01-01

    Endoscopic ultrasound (EUS) imaging of adrenal glands and its application to diagnostic procedures of adrenal diseases has been reported since 1998. It can be considered a relevant advantage in the field of adrenal diseases. Indeed, EUS allows the detection of adrenal lesions (even very small ones) and their characterization, the assessment of malignancy criteria, the early detection of neoplastic recurrences, the preoperative identification of morphologically healthy parts of the glands, the differentiation of extra-adrenal from adrenal tumors, and of the pathological entities associated with adrenal insufficiency, and the fine-needle aspiration biopsy (EUS-FNA) of suspicious lesions. At the same time, its clinical relevance depends on the experience of the endosonographer. Moreover, EUS is also by far the best and most sensitive imaging technique to detect and assess the follow-up of pancreatic manifestation of MEN1 disease. It furthermore enables the preoperatively localization of insulinomas and critical structures in their neighborhood, and may be relevant in planning surgical strategy. A positive EUS in a case of insulinoma furthermore confirms the endocrine diagnosis, especially considering the differential diagnosis of hypoglycemia factitia by oral antidiabetics. It can be supplemented by EUS-FNA. Again, it has to be considered that EUS may reveal false positive and false negative results, and the quality of the findings largely depends on the endosonographer's skills and experience. The most important technical details together with the advantages and limitations of EUS, and the pathognomonic characteristic of benign and malignant disorders of the adrenals and pancreas are presented here. © 2016 S.

As seguintes palavras-chave foram utilizadas: choque séptico, sepse, corticosteróides, insuficiência adrenal e crianças. SÍNTESE DOS DADOS: Não existe um critério bem estabelecido e aceito para definir insuficiência adrenal em pacientes criticamente enfermos. A incidência de insuficiência adrenal varia de acordo com o critério utilizado, podendo alcançar desde valores inferiores a 15% até superiores a 61%. O teste rápido de estímulo com hormônio adrenocorticotrófico (ACTH é largamente utilizado como um teste simples para a identificação de não responsividade adrenocortical, mas existe muita discussão quanto à dose de corticotropina a ser utilizada. A dose de 250 µg é a dose padrão. Recentemente, baixas doses de corticotropina (1 µg têm sido propostas, com a sugestão de que elas possam ter uma maior sensibilidade. Dúvidas ainda persistem quanto à eficácia da reposição com baixas doses de corticosteróides em crianças com choque refratário às catecolaminas. Mais estudos são necessários para determinar se o tratamento de tais pacientes alteraria morbidade e/ou mortalidade. CONCLUSÃO: Insuficiência adrenal é comum em crianças com sepse grave e choque séptico e pode contribuir para o desenvolvimento de choque refratário às catecolaminas.

    1982-06-01

    The effect of chronic (7-10 days) adrenal insufficiency on extrarenal potassium tolerance was examined by infusing potassium into rats after acute nephrectomy. The increment in plasma potassium concentration was significantly higher in glucocorticoid-replaced adrenalectomized rats versus controls (max delta PK 3.59 +/-0.11 vs. 2.93 +/- 0.08 meq/liter; P less than 0.001). The impairment in extrarenal potassium tolerance in adrenalectomized rats could not be attributed to acidemia, hypotension, changes in plasma insulin or glucose concentration, or potassium retention prior to study. Acute replacement with aldosterone resulted in significant improvement in the rise in plasma potassium after KCl (max delta PK 3.18 +/- 0.06 meq/liter; P less than 0.005 compared with aldosterone-deficient adrenalectomized rats but higher than in controls, P less than 0.02). If given on a chronic basis, aldosterone replacement led to a complete correction of the defect (max delta PK = 2.89 +/- 0.08 meq/liter). Acute epinephrine replacement in adrenalectomized rats also returned potassium tolerance to normal (max delta PK = 3.02 +/- 0.10 meq/liter). The results demonstrate that extrarenal potassium tolerance is impaired in chronic adrenal insufficiency and suggest that both aldosterone and epinephrine deficiency may contribute to the defect, since replacement with either hormone returns potassium tolerance toward normal. Accordingly, both aldosterone and epinephrine have important extrarenal mechanisms of action.

    The enlargement of suprarenal gland is related to preterm birth and the birth weight. The ultrasound measurement of fetal adrenal gland volume may identify women at risk for impending preterm birth. The aim of our study was to investigate the newborns in the region of western Slovakia followed up due to suprarenal gland enlargement. To set the ratio of prenatally diagnosed suprarenal gland enlargment, postnatal managment and treatment and interventions. The newborns with congenital adrenal hyperplasia were excluded. We have analyzed 6 years of medical records of all cases from the western Slovakia region of suprarenal gland enlargement encountered to 1st Pediatric Department, Children's University Hospital Bratislava Republic in the time period of January 2010 to Janurary 2016. The diagnosis of suprarenal gland enlargement was set by ultrasound examination performed on the 4th postnatal day as an overall screening test. Newborns with positive laboratory screening on congenital adrenal hyperplasia (CAH) were excluded from our study. We analyzed the origin of surarenal gland enlargement, gestation week on the due date, the birth weight and other comorbidities and genetic pathologies in newborns with the enlarged suprarenal glands. There were 6 newborns followed up due to suprarenal gland enlargement. All of the patients had diagnosed the adrenal haemorrhage. Adrenal lesions like adrenal cysts or neuroblastomas were not confirmed. All of the adrenal enlargements were benign with no need of other medical or surgical intervention. None of the newborn patients had other genetic abnormalities, mineral or hormonal imbalances, problems with arterial pressure or haemodynamic instability. All of the patients underwent at least 5 prenatal ultrasound tests and at least 2 postnatal ultrasound measurements. The avarage birth weight was 3030 grams (2700 grams - to 3750 grams). The avarage birth lenght was 50 cm (47 centimeter to 53 cm).The average gestation week (gw) on due date

    Full Text Available A change from group housing to isolation in unfamiliar metabolic cages represents, for rodents, a significant emotional stress. We studied the effect of candesartan, a peripheral and central angiotensin II AT1-receptor antagonist, on the hormonal and sympathetic response to acute isolation. We pretreated rats with 1 mg/kg/day candesartan for 13 days via subcutaneously implanted osmotic minipumps, followed by 24-hour isolation in individual metabolic cages. We measured brain, pituitary and adrenal angiotensin II (Ang II receptor binding by quantitative autoradiography and adrenal hormones and catecholamines by RIA and HPLC. Isolation increased adrenal catecholamines, aldosterone and corticosterone, AT1-receptor binding in the zona glomerulosa and AT2-receptor binding in the adrenal medulla. Candesartan pretreatment decreased adrenal catecholamines, aldosterone and corticosterone, AT1-receptor binding in adrenal zona glomerulosa and medulla, pituitary gland and the hypothalamic paraventricular nucleus, and AT2-receptor binding in adrenal medulla, but increased AT2-receptor binding in zona glomerulosa. We conclude that peripheral and central AT1-receptor blockade with candesartan decreases the sympatho-adrenal and hormonal response to acute stress. Our results indicate that Ang II is an important stress hormone and suggest that blockade of the physiologically active AT 1-receptors could influence stress-related disorders.

    Recent studies have shown that a minimum of approximately one-third of one normal adrenal gland is required for sufficient adrenocortical stress capacity. Correlation between intraoperative measurement, determination of remnant size by computed tomography (CT), and adrenocortical stress capacity has not been examined so far. Twenty-two patients with familial pheochromocytoma (n=13), sporadic pheochromocytoma (n=3), and adrenocortical tumors (n=6) who underwent unilateral or bilateral subtotal adrenalectomy (STAE, 28 adrenal remnants) were prospectively studied. Patients were examined in a multi-slice CT to determine residual adrenal tissue and by ACTH test 4 days and 3 months postoperatively. There was a slight significant correlation between intraoperative and CT calculated volumes (r=0.77; pSTAE has limitations. CT gives larger volumes compared with intraoperative determination. For calculation of a volume-function correlation of residual adrenal tissue, in clinical practice, the determination of relative adrenal residual volume is acceptable.

    Background: In humans, the adrenal glands and gonads undergo distinct biological events between 6-10 weeks post conception (wpc), such as testis determination, the onset of steroidogenesis and primordial germ cell development. However, relatively little is currently known about the genetic mechanisms underlying these processes. We therefore aimed to generate a detailed genomic atlas of adrenal and gonad development across these critical stages of human embryonic and fetal development. Methods: RNA was extracted from 53 tissue samples between 6-10 wpc (adrenal, testis, ovary and control). Affymetrix array analysis was performed and differential gene expression was analysed using Bioconductor. A mathematical model was constructed to investigate time-series changes across the dataset. Pathway analysis was performed using ClueGo and cellular localisation of novel factors confirmed using immunohistochemistry. Results: Using this approach, we have identified novel components of adrenal development (e.g. ASB4, NPR3) and confirmed the role of SRY as the main human testis-determining gene. By mathematical modelling time-series data we have found new genes up-regulated with SOX9 in the testis (e.g. CITED1), which may represent components of the testis development pathway. We have shown that testicular steroidogenesis has a distinct onset at around 8 wpc and identified potential novel components in adrenal and testicular steroidogenesis (e.g. MGARP, FOXO4, MAP3K15, GRAMD1B, RMND2), as well as testis biomarkers (e.g. SCUBE1). We have also shown that the developing human ovary expresses distinct subsets of genes (e.g. OR10G9, OR4D5), but enrichment for established biological pathways is limited. Conclusion: This genomic atlas is revealing important novel aspects of human development and new candidate genes for adrenal and reproductive disorders. PMID:28459107

    Functioning paragangliomas are rare tumours that produce catecholamines.They originate from extra-adrenal chromaffin cells. They are frequently malignant and are associated with high incidence of persistent or recurrent disease after their primary treatment. They are known as glomus, chemodectomas, chromaffin paragangliomas and glomerulocytomas. The location is diverse and reflects the paragangliomar distribution in the body from the base of the skull to the pelvic floor. The paragangliomas are found where there are nodes of the autonomous system, however, approximately 90% of these tumours appear in the adrenal glands (and they constitute the pheochromocytomas) and the remaining 10% is a location extra adrenal, but it has been said that its impact can be underestimated, ranging from 18% to 22% in adults and children up to 30%. The extra-adrenal are originated more frequently in the abdomen (85%), other in the chest (12%) and more rarely in the head and neck (3%). Imaging studies and measurement of non-physiological production of catecholamines may aid in the diagnosis of this entity. Surgery is the treatment of choice. It is presented the case of a primigravidas patient aged 32 with HTAIE requiring caesarean section, who had a postpartum torpid and despite to multiple antihypertensive treatments their pathology was difficult to deal, with ophthalmic complications. Some time later, the patient is studied by hyperhidrosis, laboratory tests and images are requested and it is documented incidentally, a left retroperitoneal tumour, the studies are expanded and reach the correct diagnosis. The tumour required surgical resection. The patient had a satisfactory postoperative period and she discharged with control in the external consultation. (author) [es

    Full Text Available Visceral schwannomas are extremely rare and are usually discov-ered incidentally on USG/CT-Scan. Primary schwannomas of the adrenal gland are extremely uncommon. It has been theorized that they originate from Schwann cells that insulate the nerve fi-bers innervating the adrenal medulla. Histopathological examina-tion coupled with immunohistochemistry provides the definitive diagnosis. A 55 year old normotensive female presented with pain in the right loin since 5 months. Her renal parameters were normal. Contrast enhanced computed tomography of abdomen showed a well delineated 6.5 x 5cms mass at upper pole of her right kidney. 24-hour urinary metanephrine was slightly elevated (3.07mg/24hrs. A decline in Serum cortisol levels was observed following a dexamethasone suppression test (18.89nmol/l. Histopathological examination revealed a spindle cell tumor. Immunohistochemistry showed strong and diffuse positive staining for S-100 with negative expression for CD-117, desmin, CD-34, HMB-45, synaptophysin, chromogranin, cytokeratin, and SMA. Ki-67 index was 2%.A diagnosis of cellular schwannoma of adrenal gland was confirmed.

    The present study aimed to evaluate the role of vitamins A (15000 IU/kg body wt) and α -tocopheryl acetate (100 mg/kg body wt) on repairing the disorders induced by γ -radiation on the pituitary-gonadal adrenal axis hormones in female rats during the estrus phase of estrus cycle. The investigation included the determination of follicle-stimulating hormone (FSH) estradiol (E2) progesterone (P) aldosterone (Ald), Na + , K + and Ca 2+ , levels in serum. Animals were divided into 5 groups: control, whole body -irradiated (6 Gy), injected with vitamin A 2 h before irradiation, subjected to γ -radiation then injected with α-tocopheryl acetate 1 h later and injected with vitamin A pre-irradiation, then injected with α -tocopheryl acetate post-irradiation. Animals were treated at the pro-estrus stage then, serum samples were taken at the estrus stage. Results showed that irradiation induced significant decreases in serum levels of FSH, E2, aldosterone and potassium, whereas, it elevated significantly the serum levels of P4 and sodium but there was in serum calcium levels. Both vitamins A and / orα-tocopheryl acetate succeeded to confront γ -radiation disorders on the estimated hormones and related minerals. The combination of vitamins A and α -tocopheryl acetate was more effective than either one alone

  11. Low estriol levels in the maternal marker screen as a predictor of X-linked adrenal hypoplasia congenita: Case report

    Directory of Open Access Journals (Sweden)

    Durković Jasmina

    2014-01-01

    Full Text Available Introduction. X-linked adrenal hypoplasia congenita (AHC is a rare cause of adrenocortical insufficiency. Early postnatal diagnosis may prevent severe hypoglycemia, Addisonian crises and death. Low maternal estriol (E3 levels in the second trimester of pregnancy could indicate the possibility that the fetus suffers from a disorder that causes adrenal insufficiency. Suspicion is based on the fact that E3 originates from dehydroepiandrosterone (DHEA synthesized in the fetal adrenals. In case of adrenal insufficiency, the impaired production of fetal DHEA leads to a subsequent reduction of E3 concentrations in maternal serum. There are only a few reports of AHC suspected prenatally due to low maternal E3 levels. Case Outline. We describe two brothers with adrenal insufficiency due to AHC. The older brother was admitted to the hospital at the age of 33 days due to failure to thrive, vomiting, and dehydration. Genetic analysis revealed a hemizygous mutation in DAX-1 gene, thus confirming the diagnosis of ACH. The same mutation was detected in his mother. In the second pregnancy, E3 concentrations were determined from maternal serum. Estriol levels during the second trimester were extremely low suggesting the diagnosis of AHC. The diagnosis was confirmed during the neonatal period by genetic testing, and replacement therapy was started at the age of 10 days. This boy never experienced an adverse episode such as hypoglycemia or adrenal crises. Conclusion. Since determination of E3 is a simple, sensitive, noninvasive and cheap method, its use as an obligatory prenatal screening test should be accepted as a standard practice in Serbia.

    Egan, Aoife M

    2012-01-31

    INTRODUCTION: Bilateral adrenal haemorrhage is a rare cause of adrenal failure. Clinical features are non-specific and therefore a high index of suspicion must be maintained in patients at risk. Predisposing factors include infection, malignancy and the post-operative state. CASE PRESENTATION: We report the case of a patient who underwent a left hemicolectomy with primary anastomosis and formation of a defunctioning loop ileostomy for an obstructing colon carcinoma at the splenic flexure. En-bloc splenectomy was performed to ensure an oncologic resection. The patient developed a purulent abdominal collection post-operatively and became septic with hypotension and pyrexia. This precipitated acute bilateral adrenal haemorrhage with consequent adrenal insufficiency. Clinical suspicion was confirmed by radiological findings and a co-syntropin test. Following drainage of the collection, antibiotic therapy and corticosteroid replacement, the patient made an excellent recovery. CONCLUSION: This case highlights the importance of prompt diagnosis and treatment of adrenal failure. In their absence, this condition can rapidly lead to death of the patient.

    Recent progress in the immunopathology field has greatly improved our understanding of the natural history of autoimmune diseases, particularly of Addison's disease. Addison's disease is known to be a chronic illness characterized by adrenocortical gland insufficiency that develops following a long and mainly asymptomatic period, characterized by the presence of circulating autoantibodies directed to adrenal cortex antigens. In this chapter we describe the groups of subjects at risk of developing Addison's disease, together with the diagnostic tests considered the most appropriate for evaluating adrenal function: determination of basal plasma adrenocorticotropic hormone (ACTH) levels, plasma renin activity, plasma aldosterone and cortisol levels, and cortisol levels after intravenous stimulation with ACTH (ACTH test). The employment of specific clinical, immunological and functional criteria in the subjects with autoantibodies to the adrenal cortex allows identifying those at risk of developing overt disease. The independent risk factors for the progression to adrenal failure have also been identified and they contribute to different risks of developing clinical Addison's disease. Based on the risk level, the subjects should be monitored over time to observe early signs of adrenal dysfunction, and start substitutive treatment as soon as possible. For patients presenting with high risk, prevention strategies and trials might be available. © 2016 S. Karger AG, Basel.

    Full Text Available Adrenal incidentalomas are masses accidentally discovered while conducting radiological examinations for other purposes. A major part of adrenal incidentalomas are non-functional adenomas. Silently developing Cushing's syndrome or pheochromocytoma can be observed in adrenal incidentalomas. However, coexistence of Cushing's syndrome and pheochromocytoma at the same time in the same case is quite rare. In the present study, an atypical adrenal incidentaloma case is presented, whose laboratory examinations were compatible with Subclinical Cushing's syndrome, urinary catecholamine metabolites were normal, but who histopathologically had pheochromocytoma diagnosis.

    Abstract Context It is presumed that the incidence of adrenal adenomas is symmetric between the left and right adrenal gland; however, anecdotal observations suggest a potential lateralizing asymmetry. Objective To investigate the symmetry in detection of adrenal adenomas and relevance to patient care. Design Cross-sectional and longitudinal studies. Population and Setting One thousand three hundred seventy-six patients with abdominal computed tomography or magnetic resonance imaging demonstrating benign-appearing adrenal adenomas. Main Outcome Location and size of adrenal adenomas. Results Left-sided adenomas were discovered in 65% of patients, right-sided in 21%, and bilateral adenomas in 14%. Among unilateral adenomas, 75% were left-sided. Left-sided adenomas were more prevalent than right-sided adenomas in each size category except the largest: Adrenal adenomas are substantially more likely to be identified on the left adrenal than the right. This observation may be due to detection bias attributed to the location of the right adrenal, which may preclude identification of right-sided adenomas until they are substantially larger. These findings suggest the potential for an underrecognition of right-sided adenomas that may also impair the accurate detection of bilateral adrenal diseases. PMID:29644340

    Fetal adrenal developmental status is the major determinant of fetal tissue maturation and offspring growth. We have previously proposed that prenatal ethanol exposure (PEE) suppresses fetal adrenal corticosterone (CORT) synthesis. Here, we focused on PEE-induced adrenal developmental abnormalities of male offspring rats before and after birth, and aimed to explore its intrauterine programming mechanisms. A rat model of intrauterine growth retardation (IUGR) was established by PEE (4 g/kg·d). In PEE fetus, increased serum CORT concentration and decreased insulin-like growth factor 1 (IGF1) concentration, with lower bodyweight and structural abnormalities as well as a decreased Ki67 expression (proliferative marker), were observed in the male fetal adrenal cortex. Adrenal glucocorticoid (GC)-metabolic activation system was enhanced while gene expression of IGF1 signaling pathway with steroidogenic acute regulatory protein (StAR), 3β-hydroxysteroid dehydrogenase (3β-HSD) was decreased. Furthermore, in the male adult offspring of PEE, serum CORT level was decreased but IGF1 was increased with partial catch-up growth, and Ki67 expression demonstrated no obvious change. Adrenal GC-metabolic activation system was inhibited, while IGF1 signaling pathway and 3β-HSD was enhanced with the steroidogenic factor 1 (SF1), and StAR was down-regulated in the adult adrenal. Based on these findings, we propose a “two-programming” mechanism for PEE-induced adrenal developmental toxicity: “the first programming” is a lower functional programming of adrenal steroidogenesis, and “the second programming” is GC-metabolic activation system-related GC-IGF1 axis programming. - Highlights: • Prenatal ethanol exposure induces adrenal developmental abnormality in offspring rats. • Prenatal ethanol exposure induces intrauterine programming of adrenal steroidogenesis. • Intrauterine GC-IGF1 axis programming might mediate adrenal developmental abnormality.

The subjects of the study were 6 cases of adrenal ganglioneuroma which had been histologically confirmed: the ages of the subjects ranged from 25 to 54 (mean age 41), and the maximum diameter of the tumors were 4 to 7 cm. The diagnostic methods employed in their detection were ultrasonography (US) and computed tomography (CT) in all 6 cases, magnetic resonance imaging (MRI) in 5 cases, and arteriography in 3 cases. On US and CT images, all 6 tumors had clear and smooth boundaries, and were homogeneous. They were hypoechoic on US images and low density on CT images. Of the 5 cases for which contrast CT images had been obtained, one showed a slightly heterogeneous staining. On MRI, the tumors were of lower intensity in comparison to the liver in 4 of 5 cases on the T 1 -weighted images, and the internal structure was homogeneous in 3 cases and heterogeneous in one case. The remaining one case was of isointensity and homogeneous. On the T 2 -weighted images, all 5 cases were of high intensity and heterogeneous. The blood flow distribution in the 3 tumors which were examined by Gd-DTPA dynamic MRI was low and of isointensity to the liver: 2 were heterogeneous and one was homogeneous. T 1 -enhanced images were obtained in 4 cases: 2 were of high intensity and heterogeneous, one was of isointensity and homogeneous, and one was of heterogeneously isointensity. Arteriography indicated that all 3 cases were hypovascular and no vascularization or ruptures were evident. It appeared that the imaging characteristics of adrenal ganglioneuroma were as follows: (1) homogeneous on US and CT images; (2) hypoechoic on US images, low density on CT images and little enhancement on contrast CT images; (3) of low intensity homogeneous on T 1 -weighted images and of high intensity heterogeneous on T 2 -weighted images and little blood flow distribution on dynamic MRI.

    1998-01-01

    The peculiarities of adrenal glucocorticoid function and membrane potential (MP) of zona fasciculata adrenocorticocyte (ACC) in rats after chronic x-ray exposure was studied. The changes of adrenal glucocorticoid function caused by chronic x-ray exposure within a relatively small period of irradiation (1.5 months) are obscure and manifest themselves only at physiological load. With the prolongation of the period (8 and 15 months), more considerable inhibition of the adrenal glucocorticoid function and disturbances in the membrane mechanisms of ACC MP level regulation are revealed

    Extra-adrenal paraganglioma is a rare tumor arising from the neural crest cells. Most tumors that develop in the abdomen arise from paraganglia along the paravertebral and para-aortic areas, in particular the organ of Zuckerkandl, which is close to the origin of the inferior mesenteric artery. However, extra-adrenal paraganglioma also occurs in relatively rare places such as the urinary bladder, gallbladder, hepatoduodenal ligament, and gastrointestinal tract. Here, we report imaging findings of extra-adrenal paragangliomas presenting as mesenteric and pararectal masses with lymph node metastasis.

    Musculoskeletal manifestations in chronic renal insufficiency are caused by complex bone metabolism alterations, now described under the umbrella term of chronic kidney disease mineral- and bone-related disorder (CKD-MBD), as well as iatrogenic processes related to renal replacement treatment. Radiological imaging remains the mainstay of disease assessment. This review aims to illustrate the radiological features of CKD-MBD, such as secondary hyperparathyroidism, osteomalacia, adynamic bone disease, soft-tissue calcifications; as well as features associated with renal replacement therapy, such as aluminium toxicity, secondary amyloidosis, destructive spondyloarthropathy, haemodialysis-related erosive arthropathy, tendon rupture, osteonecrosis, and infection

    The analysis of the adrenal diverging and pinhole images with 131 I-Adosterol was made to establish adrenal imaging patterns, in 43 patients with various adrenal disorders, 4 with adrenal adjacent tumors and one with arrhenoblastoma of the ovary whose images were also included. From this analysis and review of literature, three principles (1. Accumulation in cortical tumors, 2. Relation to endogenous ACTH and 3. Nonaccumulation in noncortical tumors) and several additional factors to make various adrenal imaging patterns with 131 I-iodocholesterols could be induced. The accuracy of locating the adrenal tumor-bearing glands was 97% (28/29) with pinhole images and 70% (21/30) with diverging images in baseline conditions. Various adrenal high/low ratios could not be used as confidential indicators to locate the tumorbearing glands, especially in primary aldosteronism, although the left higher ratios on both views showed high discrepancy between normal and abnormal subjects. The ''Pinhole method'' is recommended as a simple technique of adrenal imaging, because it provides a high-resolution adrenal image which results in a high diagnostic value. A pinhole collimator is available in any institute which has a gamma camera. (author)

    Full Text Available In recent years detection of various adrenal tumors has increased greatly. Total adrenalectomy remains the standart of surgical managment for adrenal tumors, although, the vast majority of these tumors turn out to be benign on the routine histological examination. Performing organ-sparing surgery would allow to avoid hormone insufficiency after total adrenalectomy. Aim: to compare results of adrenal tumors treatment by different volume of surgical interventions. Materials and methods. We evaluated the short-term results of 237 patients treatment with various adrenal tumors. Total adrenalectomy were performed on 206 cases, 31 patients undergone adrenal resection. There were analyzed intraoperative and postoperative complications, assessed the hormonal status of the patients, depending on the extent of surgical treatment. Besides, the long-term results were evaluated in 141 patients underwent total adrenalectomy and 30 patients after organ-sparing surgery. Moreover, we analyzed the percentage of recurrenses, assessed the hormonal status of the patients and the effectiveness of treatment. Results. Performing the organ-sparing operations doesn't increase the risk of intraoperative complications. In all patients with hormone-active tumors we found decline of pathologically increased hormone levels and trend to regress of clinical manifestations of the disease in early postoperative period. We found no difference in local recurrences in both groups, and its occurrence did not exceed 3.33%. Refractory postoperative adrenal insufficiency was observed only in corticosteroma patients in spite of surgery volume. In case of both side adrenal tumors there was no need in replacement therapy after total adrenalectomy from there one side and resection from the other. Conclusions. In cases of adrenal tumor performing organ-sparing operations is advisable, if there are no preoperative sings of malignancy.

    The adrenal gland is the second most common site of metastasis from a hepatocellular carcinoma (HCC). Radiofrequency ablation (RFA) for these tumors has been reported to be a potentially effective alternative to an adrenalectomy, especially for inoperable patients. However, for intermediate or large adrenal tumors, combination therapy of transarterial chemoembolization (TACE) and RFA can be attempted as it may reduce the heat sink effect. A 74-year-old patient presented with abdominal discomfort. Abdominal CT images revealed a 5.0 cm sized right adrenal mass. A percutaneous biopsy of the adrenal mass revealed a metastatic hepatocellular carcinoma. TACE was performed on the adrenal mass. However, a one-month follow-up CT image revealed a residual viable tumor. RFA was performed for the adrenal tumor six weeks after the TACE. No procedure-related major complications were noted. The serum alpha-fetoprotein level had also been normalized after the treatment, and 10-month follow-up CT images showed no definite evidence of viable adrenal tumor.

    Full Text Available Cytoplasmic inclusion bodies in adrenal medullary chromaffin cells have been described in various species including humans. These inclusions are believed to be related to certain infectious, toxic and neurodegenerative diseases. No reports concerning such adrenal inclusions have been described in bovines. Adrenal glands from twenty bovines were evaluated in a retrospective study. Seven of these exhibited inclusions - three cases of rabies, two cases of chronic suppurative bronchopneumonia, one case of chronic suppurative peritonitis, and one case of gangrenous mastitis. The inclusions were present in higher numbers especially in cases of rabies and also in one case of chronic suppurative bronchopneumonia. The inclusions were intracytoplasmic, eosinophilic, rounded, single or multiple, of various sizes, strongly stained by PAS and were present in higher numbers in the external layer of the adrenal medulla. The inclusions were negative when subjected to immunohistochemistry for detection of viral antigens in the cases of rabies. Although inclusion bodies were present in adrenal glands devoid of other histological alterations, they were more abundant in cases in which the adrenal gland had other alterations. The correlation between certain diseases and the development of inclusion bodies is not known, which highlights the importance of further studies on these inclusions in adrenal glands of bovines.

This condition commonly leads to premature menopause, defined as cessation of ovulation prior to the age of 40 years. Because there are potential immediate and long-term consequences of hypoestrogenism, a timely diagnosis is invaluable. This comprehensive review will discuss identifiable causes for primary ovarian insufficiency, including genetic disorders and metabolic abnormalities, as well as review current strategies for diagnosis, evaluation, and management of women with this condition.Keywords: premature ovarian failure, premature menopause, ovarian dysfunction

    Three patients with Cushing's disease are reported. In two patients the hyperfunction of the adrenal glands creased following selective adrenal venography, moreover hypoadrenia has developed. In the third case necrosis following venography was proved by surgery and confirmed by histology. Regarding the therapeutic possibilities of Cushing's diesease the use of this diagnostic procedure is taken into consideration but not recommended. (orig.)

    In 2015, the Australasian Pancreatic Club (APC) published the Australasian guidelines for the management of pancreatic exocrine insufficiency (http://pancreas.org.au/2016/01/pancreatic-exocrine-insufficiency-guidelines). Pancreatic exocrine insufficiency (PEI) occurs when normal digestion cannot be sustained due to insufficient pancreatic digestive enzyme activity. This may be related to a breakdown, at any point, in the pancreatic digestive chain: pancreatic stimulation; synthesis, release or transportation of pancreatic enzymes; or synchronisation of secretions to mix with ingested food. Main recommendations: The guidelines provide advice on diagnosis and management of PEI, noting the following: A high prevalence of PEI is seen in certain diseases and conditions, such as cystic fibrosis, acute and chronic pancreatitis, pancreatic cancer and pancreatic surgery. The main symptoms of PEI are steatorrhoea or diarrhoea, abdominal pain, bloating and weight loss. These symptoms are non-specific and often go undetected and untreated. PEI diagnosis is predominantly based on clinical findings and the presence of underlying disease. The likelihood of PEI in suspected patients has been categorised into three groups: definite, possible and unlikely. If left untreated, PEI may lead to complications related to fat malabsorption and malnutrition, and have an impact on quality of life. Pancreatic enzyme replacement therapy (PERT) remains the mainstay of PEI treatment with the recommended adult initial enzyme dose being 25 000-40 000 units of lipase per meal, titrating up to a maximum of 75 000-80 000 units of lipase per meal. Adjunct acid-suppressing therapy may be useful when patients still experience symptoms of PEI on high dose PERT. Nutritional management by an experienced dietitian is essential. Changes in management as a result of these guidelines: These are the first guidelines to classify PEI as being definite, possible or unlikely, and provide a diagnostic algorithm to

    To evaluate the characteristic MRI findings of pubic insufficiency fracture. In nine cases of pubic insufficiency fracture, the findings of plain radiography (n=9), MRI (n=9), and bone scintigraphy (n=8) were reviewed. We retrospectively analyzed, with regard to fracture site, the destructive pattern revealed by plain radiography, and uptake by other pelvic bones, as demonstrated by RI bone scanning. The MR findings evaluated were the fracture gap and its signal intensity, the site and signal intensity of the soft tissue mass, and other pelvic bone fractures. Plain radiography revealed osteolysis and sclerosis of pubic bone in eight of nine cases (89%), and parasymphyseal fractures in seven (78%). RI indicated uptake by the sacrum in six cases (66%), and by the ilium in three (33%). MR findings of fracture gap (seven cases, 78%) were hypo to isointensity on T1WI, hyper intensity on T2WI and the absence of contrast enhancement. Soft tissue masses were found in seven cases (78%); in four of these the location was parasymphyseal, and in three, surrounding muscle was involved. Hypo to isointensity was revealed by T1WI, hyperintensity by T2WI, and there was peripheral enhancement. Other associated pelvic bone fractures involved the sacrum in seven cases and the ilium in four. The characteristic MR findings of pubic insufficiency fracture were parasymphyseal location, fracture gap, peripherally enhanced soft tissue mass formation, and fractures of other pelvic bones, namely the sacrum and ilium

    1984-01-01

    In order to investigate the mechanism of uptake of meta-iodobenzylguanidine (mIBG) by the adrenal glands, autoradiographic and pharmacologic studies were performed in mice and dogs receiving radioiodinated mIBG. In mice, on macroautoradiography of whole body section 48 h after 125 I-mIBG, most of the radioactivity was focused in the adrenal glands. On microautoradiography, silver grains were exclusively located in the adrenal medulla. Time counting after phenoxybenzamine, cocaine, and desipramine treatment resulted in 45%, 35%, and 0% inhibition of mIBG uptake, respectively. Tissue counting and scintigraphic studies demonstrated a more than 50% mIBG release from the adrenal glands. These data indicate the high affinity of mIBG for adrenal medulla and suggest that the mIBG and catecholamine uptake mechanisms are onlt partially the same. (orig.)

    Several forms of congenital adrenal hyperplasia are potentially fatal if unrecognized and untreated. The aim of this study is to throw light on the clinical presentation together with chromosomal and laboratory associations in this syndrome. Twenty four patients diagnosed as congenital adrenal hyperplasia were referred from the Diabetic Endocrine Metabolic Pediatric Unit [DEMPU], Children's Hospital, Cairo University for hormonal and chromosomal workup. Twenty two patients were diagnosed as classic congenital adrenal hyperplasia (CAH) syndrome. Sever salt wasting form was present in ten patients whereas simple virilization was the presenting manifestation in twelve patients. Two patients presented as late onset congenital adrenal hyperplasia (LOCAH). The mean age was 3.18 years, ranging from eight months to 19 years. The sex of rearing was Female in 18 cases and male in six cases. Genitography and sonography confirmed the presence of female internal organs in all cases. Advanced bone age was evident by radiographic studies. Although the karyotyping was (46,XX) in all cases, the correct sex diagnosis was delayed in 6 cases. Serum concentrations of 17-hydroxyprogesterone (17.OH.P); Dehydroepiandrosterone sulfate (DHEAS); Delta,4-androstenedione (D 4 A); Testosterone and 11-deoxycortisol were all elevated in relation to controls. We found that the adrenal androgens DHEAS, delta 4A, and T were more elevated in salt losers when compared to simple virilizing patients. However, this difference was not of statistical significance. The present study demonstrates that clinical examination and laboratory investigations are necessary for early detection and treatment of hese cases to avoid major medical and psychological problems for the patients and their parents.

  4. Adrenal Mass Causing Secondary Hypertension.

    Robinson, Darlene Y

    2015-11-01

    Most hypertensive patients have essential (primary) hypertension; only 5% to 10% have a secondary cause. Two clinical characteristics suggestive of secondary hypertension are early onset (hypertension (>180/110 mm Hg). When faced with these findings, clinicians should consider a secondary cause of hypertension. A 22-year-old woman being evaluated for asthma exacerbation in the emergency department was noted to have severe persistent hypertension. Additional evaluation revealed severe hypokalemia, metabolic alkalosis, and hypernatremia. The patient was admitted to the hospital for blood pressure management, electrolyte replacement, and further evaluation of presumed hyperaldosteronism. Diagnostic imaging revealed a large adrenal mass. Surgical resection was performed, leading to a diagnosis of hyperaldosteronism caused by adrenal carcinoma. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: Secondary hypertension is far less common than essential hypertension; however, considering the large volume of patients seen in emergency departments, it is likely that some will have secondary hypertension. Emergency physicians should be aware of the clinical characteristics that suggest secondary hypertension so that the appropriate diagnostic and treatment pathways can be pursued.

    2016-01-01

    Congenital adrenal hyperplasia (CAH) describes a family of disorders that comes from enzymatic deficiencies in cortisol production, with 21-hydroxylase deficiency causing ∼90% of cases. Distinction is made between the severe classical form and milder nonclassical form of CAH. Molecular genetic analysis is used to confirm the hormonal diagnosis. A high rate of genotype-phenotype disconcordance has been found in 21-hydroxylase deficiency. The goal of treatment is to replace with synthetic glucocorticoids and mineralocorticoids and suppress adrenal androgen production. The treatment of patients affected with nonclassical CAH, particularly males, remains controversial. Variable synthetic glucocorticoids are used and new modes of glucocorticoid delivery are under investigation. To improve height, growth hormone and other adjuvant therapies are employed. Long-term outcomes of genital surgery using modern techniques in females affected with classical CAH continue to be investigated. Prenatal treatment with dexamethasone is available to avoid ambiguous genitalia in these females. Although studies have shown its safety to mother and fetus, prenatal treatment is still regarded as experimental. Currently, prenatal diagnosis of CAH can only be obtained through invasive methods. Recently, the detection of cell-free fetal DNA in maternal plasma has made it possible to make this diagnosis earlier and noninvasively. © 2016 S. Karger AG, Basel.

  6. Dynamics of adrenal steroids are related to variations in Th1 and Treg populations during Mycobacterium tuberculosis infection in HIV positive persons.

    Directory of Open Access Journals (Sweden)

    Maria Florencia Quiroga

    Full Text Available Tuberculosis (TB remains the most frequent cause of illness and death from an infectious agent, and its interaction with HIV has devastating effects. We determined plasma levels of dehydroepiandrosterone (DHEA, its circulating form DHEA-suphate (DHEA-s and cortisol in different stages of M. tuberculosis infection, and explored their role on the Th1 and Treg populations during different scenarios of HIV-TB coinfection, including the immune reconstitution inflammatory syndrome (IRIS, a condition related to antiretroviral treatment. DHEA levels were diminished in HIV-TB and HIV-TB IRIS patients compared to healthy donors (HD, HIV+ individuals and HIV+ individuals with latent TB (HIV-LTB, whereas dehydroepiandrosterone sulfate (DHEA-s levels were markedly diminished in HIV-TB IRIS individuals. HIV-TB and IRIS patients presented a cortisol/DHEA ratio significantly higher than HIV+, HIV-LTB and HD individuals. A positive correlation was observed between DHEA-s and CD4 count among HIV-TB individuals. Conversely, cortisol plasma level inversely correlated with CD4 count within HIV-TB individuals. M. tuberculosis-specific Th1 lymphocyte count was increased after culturing PBMC from HIV-TB individuals in presence of DHEA. We observed an inverse correlation between DHEA-s plasma level and Treg frequency in co-infected individuals, and CD4+FoxP3+ Treg frequency was increased in HIV-TB and IRIS patients compared to other groups. Strikingly, we observed a prominent CD4+CD25-FoxP3+ population across HIV-TB and HIV-TB IRIS patients, which frequency correlated with DHEA plasma level. Finally, DHEA treatment negatively regulated FoxP3 expression without altering Treg frequency in co-infected patients. These data suggest an enhancing role for DHEA in the immune response against M. tuberculosis during HIV-TB coinfection and IRIS.

  8. Patient-specific workup of adrenal incidentalomas

    Directory of Open Access Journals (Sweden)

    Romy R. de Haan

    Full Text Available Purpose: : To develop a clinical prediction model to predict a clinically relevant adrenal disorder for patients with adrenal incidentaloma. Materials and methods: : This retrospective study is approved by the institutional review board, with waiver of informed consent. Natural language processing is used for filtering of adrenal incidentaloma cases in all thoracic and abdominal CT reports from 2010 till 2012. A total of 635 patients are identified. Stepwise logistic regression is used to construct the prediction model. The model predicts if a patient is at risk for malignancy or hormonal hyperfunction of the adrenal gland at the moment of initial presentation, thus generates a predicted probability for every individual patient. The prediction model is evaluated on its usefulness in clinical practice using decision curve analysis (DCA based on different threshold probabilities. For patients whose predicted probability is lower than the predetermined threshold probability, further workup could be omitted. Results: : A prediction model is successfully developed, with an area under the curve (AUC of 0.78. Results of the DCA indicate that up to 11% of patients with an adrenal incidentaloma can be avoided from unnecessary workup, with a sensitivity of 100% and specificity of 11%. Conclusion: : A prediction model can accurately predict if an adrenal incidentaloma patient is at risk for malignancy or hormonal hyperfunction of the adrenal gland based on initial imaging features and patient demographics. However, with most adrenal incidentalomas labeled as nonfunctional adrenocortical adenomas requiring no further treatment, it is likely that more patients could be omitting from unnecessary diagnostics.

  9. Testicular adrenal rest tumor in infertile man with congenital adrenal hyperplasia: case report and literature review

    Directory of Open Access Journals (Sweden)

    Giovanni Scala Marchini

    Full Text Available CONTEXT: Synthesis of cortisol and aldosterone is impaired in patients with congenital adrenal hyperplasia (CAH because of 21-hydroxylase deficiency. Men with CAH have low fertility rates compared with the normal population, and this is related to testicular adrenal rest tumors. Findings of azoospermia in combination with a testicular tumor on ultrasound are likely to have a mechanical cause, especially when in the testicular mediastinum. The preferred treatment method consists of intensive corticoid therapy. However, when the tumor is unresponsive to steroid therapy, surgical treatment should be considered. CASE REPORT: We present the case of a male patient with CAH due to 21-hydroxylase deficiency who presented a testicular tumor and azoospermia. Treatment with low daily corticoid doses had previously been started by an endocrinologist, but after 12 months, no significant change in sperm count was found. Although the adrenocorticotrophic hormone and 17-hydroxyprogesterone levels returned to normal values, the follicle-stimulating hormone (FSH, luteinizing hormone and testosterone levels remained unchanged. Ultrasound examination confirmed that the testicles were small and heterogenous bilaterally, and revealed a mosaic area at the projection of the testis network bilaterally. Magnetic resonance imaging confirmed the finding. Testicular biopsy revealed the presence of preserved spermatogenesis and spermiogenesis in 20% of the seminiferous tubules in the right testicle. The patient underwent testis-sparing tumor resection. After 12 months of follow-up, there was no tumor recurrence but the patient still presented azoospermia and joined an intracytoplasmic sperm injection program.

    We present a case of unilateral adrenal medullary hyperplasia in a 63-year-old woman with clinical signs and symptoms of pheochromocytoma unassociated with multiple endocrine neoplasia. The surgically removed adrenal gland revealed diffuse medullary hyperplasia with multiple micronodules measuring up to 2 mm. The micronodules were composed of enlarged chromaffin cells with atypia, histologically similar to those of pheochromocytoma, forming small solid alveolar patterns separated by a fibrovascular stroma. Removal of the hyperplastic adrenal gland resulted in disappearance of paroxysmal nocturnal hypertension and palpitation. These results suggest that diffuse and nodular medullary hyperplasia is the precursor of pheochromocytoma.

    Ewing's sarcoma usually arises in the bones of children and adolescents. We herein report a 74-year-old man with Ewing's sarcoma in the adrenal gland. The diagnosis was confirmed by a genetic test, pathological studies, and several imaging studies. He already had multiple liver metastases when he was transferred to our hospital and died on the 37th day. The diagnosis was further confirmed by autopsy studies. Adrenal Ewing's sarcoma is very rare, and our patient was older than other reported cases. Ewing's sarcoma should be considered even in elderly patients with adrenal tumors.

    2012-06-01

    A 56-year-old woman presented with an incidental adrenal adenoma and physical examination findings that included moderate obesity, a slight cervicothoracic fat pad ("buffalo hump"), increased supraclavicular fat pads, and white abdominal striae. Biochemical workup revealed elevated levels of 24-hour urinary free cortisol but normal serum morning cortisol and suppressed levels of corticotropin, suggestive of adrenal-dependent Cushing syndrome. The resected adrenal gland revealed macronodular cortical hyperplasia with a dominant nodule. Other findings included an absent cortisol response to corticotropin stimulation, presence of serum anti-21-hydroxylase antibodies, and mononuclear cell infiltration--consistent with adrenalitis. The findings represent, to the authors' knowledge, the first known case of a patient with coexistent functional cortisol-secreting macronodular adrenal tumor resulting in Cushing syndrome and immune-mediated adrenalitis resulting in Addison disease.

    Despite continuous efforts for an optimal steroid replacement, recent observations suggest increased cardiometabolic risk and related mortality in primary adrenal insufficiency (PAI). Adipokines are peptides from the adipose tissue, markers of cardiometabolic dysfunction. This study was aimed to evaluate serum levels of adipokines: leptin, adiponectin, and resistin in PAI during conventional steroid substitution. The analysis comprised 63 patients (mean age 42.7 ± 14.1 years) and 63 healthy controls. Serum adipokines, lipid profile, and plasma glucose were assessed in both cohorts. ACTH, serum insulin, HOMA-IR, DHEA-S, cortisol and 24 h urinary free cortisol were determined in PAI. Body mass composition was analyzed by Dual-Energy X-ray Absorptiometry. Mean BMI in the control group was 24.1 ± 3.9 kg/m(2) and 23.7 ± 3.9 kg/m(2) in the PAI cohort. Serum leptin and adiponectin levels were similar in both groups, whereas resistin appeared significantly lower among affected subjects (p = 0.0002). Its levels were weakly correlated with HOMA-IR (p = 0.048). Leptin was independently correlated with fasting insulin, HOMA-IR, BMI, and body fat (p regression analysis only weight (p = 0.017), total and HDL cholesterol (p replacement. Serum adipokines in treated PAI follow similar correlations to those reported in healthy subjects. Further prospective studies are warranted to verify and explain plausible excess of cardiovascular mortality in PAI.

    Congenital adrenal hyperplasia (CAH) is an inherited autosomal recessive disorder characterized by insufficient production of cortisol. The aim of this case report was to present a child with CAH, premature exfoliation of primary teeth and accelerated eruption of his permanent teeth related to bone resorption. A 4.5-year-old Caucasian boy with CAH and long-term administration of glucocorticoids was referred for dental restoration. Clinical examination revealed primary molars with worn stainless steel crowns, severe attrition of the upper canines, and absence of the upper incisors. Before the completion of treatment, abnormal mobility of the first upper primary molars and the lower incisors was detected, and a few days later the teeth exfoliated prematurely. Histologic examination revealed normal tooth structure. Alkaline phosphatase and blood cells values were normal. Eruption of the permanent dentition was also accelerated. Tooth mobility was noticed in the permanent teeth as soon as they erupted, along with bone destruction. Examination revealed an elevated level of receptor activator of nuclear factor-κB ligand and lower-than-normal osteoprotegerin and vitamin D levels. The patient was treated with vitamin D supplements, and his teeth have been stable ever since. CAH is a serious chronic disorder appearing in children with accelerated dental development and possibly premature loss of primary teeth. Copyright © 2015 by the American Academy of Pediatrics.

    Before surgery for primary aldosteronism (PA), localization is evaluated with adrenal vein sampling (AVS). A 56-year-old Japanese woman had a right adrenal mass, hypokalemia, and a high aldosterone/renin ratio. Stress tests confirmed the diagnosis of PA. Subsequently, preoperative AVS was performed and right adrenal hemorrhage (AH) occurred unexpectedly. Because hypertension persisted, laparoscopic right adrenalectomy was performed. Postoperatively, the blood pressure was normalized. Pathological examination revealed an adrenal cortical adenoma largely unaffected by necrosis and hemorrhage. Previous reports have also indicated that AH may not ameliorate PA. We discussed the clinical progress of AH and the measures to prevent causing AH.

    Full Text Available A functional lesion in corticotrophin (ACTH-independent Cushing’s syndrome is difficult to distinguish from lesions of bilateral adrenal masses. Methods for distinguishing these lesions include adrenal venous sampling and 131I-6β-iodomethyl-19-norcholesterol (131I-NP-59 scintigraphy. We present a case of a 29-year-old Han Chinese female patient with a history of hypercholesterolaemia and polycystic ovary syndrome. She presented with a 6month history of an 8kg body weight gain and gradual rounding of the face. Serial examinations revealed loss of circadian rhythm of cortisol, elevated urinary free-cortisol level and undetectable ACTH level (<5pg/mL. No suppression was observed in both the low- and high-dose dexamethasone suppression tests. Adrenal computed tomography revealed bilateral adrenal masses. Adrenal venous sampling was performed, and the right-to-left lateralisation ratio was 14.29. The finding from adrenal scintigraphy with NP-59 was consistent with right adrenal adenoma. The patient underwent laparoscopic right adrenalectomy, and the pathology report showed adrenocortical adenoma. Her postoperative cortisol level was 3.2μg/dL, and her Cushingoid appearance improved. In sum, both adrenal venous sampling and 131I-NP-59 scintigraphy are good diagnostic methods for Cushing’s syndrome presenting with bilateral adrenal masses.

    Incidental adrenal tumors are lesions occasionally observed during abdominal US or CT scans. These tumors have been observed in patients without clinical or laboratorial signs of adrenal disease. The authors report a case of a 18 - years - old young man who was admitted to the Franco da Rocha Hospital, Sao Paulo, with abdominal pain and a palpated mass in the epigastrium which began one month ago. These findings were preceded by a blunt trauma at the epigastrium three months earlier. First clinical hypothesis was of a traumatic pancreatic pseudocyst. However, investigation and laparotomy showed a large left adrenal solid mass, weighting 700 g. The mass was removed and histology was performed. There was no evidence of malignant neoplasm, then the diagnostic of incidental adenoma of adrenal was confirmed. The authors hope to stimulate surgeons for early detection of these lesions in order to prevent the complications and improve the prognosis. (author)

    2014-03-01

    Full Text Available Adrenal myelolipomas are rare benign tumors of the adrenal cortex composed of adipose and hematopoietic cells. They have been postulated to arise from repeated stimulation by stress, inflammation and ACTH oversecretion. Myelolipomas are usually detected incidentally on imaging and do not require any active intervention besides regular follow-up by imaging. However, myelolipomas may insidiously grow to large sizes and cause mass effects and hemorrhage. Timely diagnosis and surgical resection are curative and lifesaving.

    Adrenal hemorrhage (AH) is a well-described complication of the neonatal period, anticoagulant therapy, and overwhelming bacterial infection especially with N. meningitis. Until recently the diagnosis of acute AH was based predominantly on autopsy findings. Ultrasound and computed tomography examinations have been successfully used for antemortem detection of AH in neonates and anticoagulated patients. We report two patients with fulminant meningococcal infection who demonstrated bilateral adrenal hemorrhages on ultrasonography. (orig.)

  3. Classic congenital adrenal hyperplasia and puberty.

    2004-11-01

    Congenital adrenal hyperplasia (CAH) is a group of autosomal recessive disorders resulting from deficiency of one of the five enzymes required for synthesis of cortisol in the adrenal cortex. The most common form of the disease is classic 21-hydroxylase deficiency, which is characterized by decreased synthesis of glucocorticoids and often mineralocorticoids, adrenal hyperandrogenism and impaired development and function of the adrenal medulla. The clinical management of classic 21-hydroxylase deficiency is often suboptimal, and patients are at risk of developing in tandem iatrogenic hypercortisolism and/or hyperandogenism. Limitations of current medical therapy include the inability to control hyperandrogenism without employing supraphysiologic doses of glucocorticoid, hyperresponsiveness of the hypertrophied adrenal glands to adrenocorticotropic hormone (ACTH) and difficulty in suppressing ACTH secretion from the anterior pituitary. Puberty imposes increased difficulty in attaining adrenocortical suppression despite optimal substitution therapy and adherence to medical treatment. Alterations in the endocrine milieu at puberty may influence cortisol pharmacokinetics and, consequently, the handling of hydrocortisone used as replacement therapy. Recent studies have demonstrated a significant increase in cortisol clearance at puberty and a shorter half-life of free cortisol in pubertal females compared with males. Furthermore, children with classic CAH have elevated fasting serum insulin concentrations and insulin resistance. The latter may further enhance adrenal and/or ovarian androgen secretion, decrease the therapeutic efficacy of glucocorticoids and contribute to later development of the metabolic syndrome and its complications.

  4. Review of Outcome Information in 46,XX Patients with Congenital Adrenal Hyperplasia Assigned/Reared Male: What Does It Say about Gender Assignment?

    Directory of Open Access Journals (Sweden)

    Lee PeterA

    2010-12-01

    Full Text Available There is ample historical verification of 46,XX congenital adrenal hyperplasia (CAH patients being born with essentially male genitaliawhile outcome information is scant. Prior to glucocorticoid therapy, most patients died very young from adrenal insufficiency. Most available reports from laterchildhood, contain little information concerning sexual identity. Reports on older individuals lack adequate information about sexual identity and quality of life. The difficulty in assessing the relative impact of multiple dynamic environmental factors on the development of sexual identity, self- and body esteem and overall adjustment to life is clear. Nevertheless, it remains unclear whether those infants whose masculine genitalia at birth resulted in an initial male assignment would have enjoyed a better adult outcome had they been allowed to remain male rather than the female reassignment that most received. Further, one could ask whether a male sex of rearing should be considered in 46,XX CAH infants with male external genitalia. After reviewing available literature, we conclude that because those extremely virlized 46,XX CAH patients who were reared male with healthy social support demonstrated satisfactory levels of social and sexual function as adults a male sex assignment should be considered in these types of infants when social and cultural environment are supportive.

  6. Biosynthesis and metabolism of steroid hormones by human adrenal carcinomas

    Directory of Open Access Journals (Sweden)

    Brown J.W.

    2000-01-01

    Full Text Available Over a 15-year period, our university-based laboratory obtained 125 adrenal tumors, of which 15 (12% were adrenal cortical carcinomas. Of these, 6 (40% of the carcinomas occurred in patients with clear clinical manifestations of steroid hormone excess. Adrenal cortical carcinoma cells derived from the surgically resected tumors in 4 of these patients were isolated and established in primary culture. Radiotracer steroid interconversion studies were carried out with these cultures and also on mitochondria isolated from homogenized tissues. Large tumors had the lowest steroidogenic activities per weight, whereas small tumors had more moderately depressed enzyme activities relative to cells from normal glands. In incubations with pregnenolone as substrate, 1 mM metyrapone blocked the synthesis of corticosterone and cortisol and also the formation of aldosterone. Metyrapone inhibition was associated with a concomitant increase in the formation of androgens (androstenedione and testosterone from pregnenolone. Administration of metyrapone in vivo before surgery in one patient resulted in a similar increase in plasma androstenedione, though plasma testosterone levels were not significantly affected. In cultures of two of four tumors examined, dibutyryl cAMP stimulated 11ß-hydroxylase activity modestly; ACTH also had a significant stimulatory effect in one of these tumors. Unlike results obtained with normal or adenomatous adrenal cortical tissues, mitochondria from carcinomatous cells showed a lack of support of either cholesterol side-chain cleavage enzyme complex or steroid 11ß-hydroxylase activity by Krebs cycle intermediates (10 mM isocitrate, succinate or malate. This finding is consistent with the concept that these carcinomas may tend to function predominantly in an anaerobic manner, rather than through the oxidation of Krebs cycle intermediates.

    1988-01-01

    The aim of the present study was to investigate if the postulated deficient adrenal androgen secretion in Anorexia Nervosa (AN), could be associated with a status of sustained dopaminergic hyperactivity. The adrenal responses to ACTH and PRL response to dopaminergic receptor blockade were studied in seven patients with Anorexia Nervosa and seven regularly menstruating women. AN patients showed lower baseline DHEA-sulphate (DHEA-S), androstenedione (Adione) and prolactin (PRL) levels than controls. The response to ACTH revealed evidences of significantly decreased 17-20 desmolase activity in AN, with apparent predominance of glucocorticoid over androgenic pathways relative to controls. Because dopaminergic receptor blockade with Domperidone (DOM) showed intense dopaminergic hyperactivity in AN, we postulate that the adrenal regression seen in the disease is the consequence of a reduced zona reticularis as a consequence of the lack of trophic support by PRL and/or intermediate lobe proopiomelanocortin (IL-POMC). This is consistent with our previous results in pre-adrenarchal dogs and rabbits.

    The purpose of this study was to describe the range of appearances of adrenal phaeochromocytomas on T2-weighted MRI, correlate appearances with histopathology, and quantify the incidence of the previously described hyperintense appearance. The appearance and MR characteristics of 44 phaeochromocytomas were reviewed retrospectively. T2-weighted appearances were grouped: (1) 'classical', homogeneous, high signal intensity, isointense to CSF; (2) homogeneous, isointense or minimally hyperintense to spleen, hypointense to CSF; (3) heterogeneous, marbled appearance; (4) heterogeneous, multiple high signal intensity pockets. All 44 adrenal phaeochromocytomas were well circumscribed, 1.2-15 cm in maximum diameter, with no visual or quantitative signal loss on chemical shift imaging. On T2-weighted MRI 5/44 (11%) had group 1 appearance; 15/44 (34%) group 2, 7/44 (16%) group 3; and 17/44 (39%) group 4. Homogeneous group 1 and 2 lesions were smaller (mean 4.5 cm) than heterogeneous group 3 and 4 lesions (mean 6.3 cm). Increasing MRI heterogeneity correlated pathologically with increasing amounts of haemorrhage, necrosis and fibrosis. No MRI features were predictive of malignancy. Non-functioning phaeochromocytomas were larger than functioning lesions. No size difference was seen between syndrome and sporadic lesions. In this large series we report a wide range of appearances of adrenal phaeochromocytomas on T2-weighted MRI. The previously described classical hyperintense phaeochromocytoma is relatively uncommon.

    2005-12-01

    Adrenal androgen excess is found in approximately 25-60% of women with polycystic ovary syndrome (PCOS), but the mechanisms underlying PCOS-related adrenal androgen excess are unclear. The objective of this study was to determine whether adrenal androgen excess is manifest in a nonhuman primate model for PCOS. Six prenatally androgenized (PA) and six control female rhesus monkeys of similar age, body weight, and body mass index were studied during d 2-6 of two menstrual cycles or anovulatory 30-d periods. Predexamethasone adrenal steroid levels were assessed in the first cycle (cycle 1). In a subsequent cycle (cycle 2), occurring one to three cycles after cycle 1, adrenal steroids were determined 14.5-16.0 h after an i.m. injection of 0.5 mg/kg dexamethasone (postdexamethasone levels) and after an i.v. injection of 50 microg ACTH-(1-39). Both before and after dexamethasone, serum levels of dehydroepiandrosterone (DHEA) in PA females exceeded those in controls. After ACTH injection, PA females exhibited higher circulating levels of DHEA, androstenedione, and corticosterone but comparable levels of 17alpha-hydroxyprogesterone, cortisol, the sulfoconjugate of DHEA, and testosterone compared with controls. Enhanced basal and ACTH-stimulated adrenal androgen levels in PA female monkeys may reflect up-regulation of 17,20 lyase activity in the adrenal zona reticularis, causing adrenal androgen excess comparable with that found in PCOS women with adrenal androgen excess. These findings open the possibility that PCOS adrenal hyperandrogenism may have its origins in fetal androgen excess reprogramming of adrenocortical function.

    Purpose. To determine rate of convergence insufficiency (CI) and accommodative insufficiency (AI) and assess the relation between CI, AI, visual symptoms, and astigmatism in school-age children. Methods. 3rd-8th-grade students completed the Convergence Insufficiency Symptom Survey (CISS) and binocular vision testing with correction if prescribed. Students were categorized by astigmatism magnitude (no/low: <1.00 D, moderate: 1.00 D to <3.00 D, and high: ≥3.00 D), presence/absence of clinical signs of CI and AI, and presence of symptoms. Analyses determine rate of clinical CI and AI and symptomatic CI and AI and assessed the relation between CI, AI, visual symptoms, and astigmatism. Results. In the sample of 484 students (11.67 ± 1.81 years of age), rate of symptomatic CI was 6.2% and symptomatic AI 18.2%. AI was more common in students with CI than without CI. Students with AI only (p = 0.02) and with CI and AI (p = 0.001) had higher symptom scores than students with neither CI nor AI. Moderate and high astigmats were not at increased risk for CI or AI. Conclusions. With-the-rule astigmats are not at increased risk for CI or AI. High comorbidity rates of CI and AI and higher symptoms scores with AI suggest that research is needed to determine symptomatology specific to CI.

    We compare 1,5 T magnetic resonance (MR) image findings in 193 patients with congenital pituitary congenital insufficiency. One hundred and thirty nine of the MR studies were obtained in patients who had isolated growth hormone deficiency. Other fifth - four patients had multiple pituitary hormone deficiency. On MR images, normal anterior and posterior lobes of the pituitary glands can be clearly differentiated because the posterior lobe has a characteristic high intensity on TI-weighted images. In fifty-four patients, the high- intensity of the posterior lobe was not seen, but a similar high signal intensity was observed at the proximal stump in fifty-one patients. this high- intensity area is the newly formed ectopic posterior lobe, which also secrets anti-diuretic hormone just as the posterior lobe would. MR imaging can demonstrate the transection of the pituitary stalk and the formation of the ectopic lobe, revealing to be a useful diagnostic tool in the definition of the type of alteration in growth defects of endocrine origin.

    2006-07-01

    Full Text Available BACKGROUND: Sustained lymph stagnation engenders a pathological response that is complex and not well characterized. Tissue inflammation in lymphedema may reflect either an active or passive consequence of impaired immune traffic. METHODS AND FINDINGS: We studied an experimental model of acute post-surgical lymphedema in the tails of female hairless, immunocompetent SKH-1 mice. We performed in vivo imaging of impaired immune traffic in experimental, murine acquired lymphatic insufficiency. We demonstrated impaired mobilization of immunocompetent cells from the lymphedematous region. These findings correlated with histopathological alterations and large-scale transcriptional profiling results. We found intense inflammatory changes in the dermis and the subdermis. The molecular pattern in the RNA extracted from the whole tissue was dominated by the upregulation of genes related to acute inflammation, immune response, complement activation, wound healing, fibrosis, and oxidative stress response. CONCLUSIONS: We have characterized a mouse model of acute, acquired lymphedema using in vivo functional imaging and histopathological correlation. The model closely simulates the volume response, histopathology, and lymphoscintigraphic characteristics of human acquired lymphedema, and the response is accompanied by an increase in the number and size of microlymphatic structures in the lymphedematous cutaneous tissues. Molecular characterization through clustering of genes with known functions provides insights into processes and signaling pathways that compose the acute tissue response to lymph stagnation. Further study of genes identified through this effort will continue to elucidate the molecular mechanisms and lead to potential therapeutic strategies for lymphatic vascular insufficiency.

    Duan, Kai; Gomez Hernandez, Karen; Mete, Ozgur

    2015-03-01

    Endogenous Cushing's syndrome is a rare endocrine disorder that incurs significant cardiovascular morbidity and mortality, due to glucocorticoid excess. It comprises adrenal (20%) and non-adrenal (80%) aetiologies. While the majority of cases are attributed to pituitary or ectopic corticotropin (ACTH) overproduction, primary cortisol-producing adrenal cortical lesions are increasingly recognised in the pathophysiology of Cushing's syndrome. Our understanding of this disease has progressed substantially over the past decade. Recently, important mechanisms underlying the pathogenesis of adrenal hypercortisolism have been elucidated with the discovery of mutations in cyclic AMP signalling (PRKACA, PRKAR1A, GNAS, PDE11A, PDE8B), armadillo repeat containing 5 gene (ARMC5) a putative tumour suppressor gene, aberrant G-protein-coupled receptors, and intra-adrenal secretion of ACTH. Accurate subtyping of Cushing's syndrome is crucial for treatment decision-making and requires a complete integration of clinical, biochemical, imaging and pathology findings. Pathological correlates in the adrenal glands include hyperplasia, adenoma and carcinoma. While the most common presentation is diffuse adrenocortical hyperplasia secondary to excess ACTH production, this entity is usually treated with pituitary or ectopic tumour resection. Therefore, when confronted with adrenalectomy specimens in the setting of Cushing's syndrome, surgical pathologists are most commonly exposed to adrenocortical adenomas, carcinomas and primary macronodular or micronodular hyperplasia. This review provides an update on the rapidly evolving knowledge of adrenal Cushing's syndrome and discusses the clinicopathological correlations of this important disease.

    Full Text Available Objective. The most common form of congenital adrenal hyperplasia (CAH is 21-hydroxylase (21-OH deficiency due to mutation of the CYP21A2 gene. Patients with nonclassical CAH (NC-CAH are usually asymptomatic at birth and typically present in late childhood, adolescence, or adulthood with symptoms of excessive androgen secretion. Subfertility is relative in NC-CAH, but the incidence of spontaneous miscarriage is higher. Here, we report a previously undiagnosed female who gave birth to a normal male child and is planning to become pregnant again. Case Report. A 32-year-old female was referred to our clinic for obesity. Her medical history revealed that she had had three pregnancies. She was planning to become pregnant again. Her laboratory results revealed that she had NC-CAH. Since her husband is the son of her aunt and she had miscarriages and intrauterin exitus in her history, their genetic analyses were performed. Conclusion. Since most patients with NC-CAH have a severe mutation, these patients may give birth to a child with the classical CAH (C-CAH if their partner is also carrying a severe mutation. Females with NC-CAH who desire pregnancy must be aware of the risk of having an infant with C-CAH.

    2013-12-01

    Glottal closure is an important part of the mechanism that protects the airway during the normal swallow. Glottal insufficiency disrupts glottal closure and therefore puts patients at risk of aspiration. Treatment of glottal insufficiency can be classified as surgical or nonsurgical. The objective of treating glottal insufficiency is to avoid aspiration or penetration of secretions or food into the airway. Nonsurgical treatment consists of swallowing maneuvers and other measures. Surgical treatment of glottal insufficiency includes injection laryngoplasty, medialization thyroplasty with or without arytenoid adduction or with arytenopexy and cricothyroid subluxation, hypopharyngoplasty, cricopharynx muscle dilation, and cricopharynx myotomy.

    Adrenal computed tomographic (CT) scanning was conducted in twelve patients with Addison's disease during the clinical course. In tuberculous Addison's disease (n=8), three of four patients examined during the first two years after disease onset had bilaterally enlarged adrenals, while one of four had a unilaterally enlarged one. At least one adrenal gland was enlarged after onset in all six patients examined during the first four years. Thereafter, the adrenal glands was atrophied bilaterally, in contrast to adrenal glands in idiopathic Addison's disease which was atrophied bilaterally from disease onset (n=2). Adrenal calcification was a less sensitive clue in tracing pathogenesis, i.e., adrenal calcification was observed in five of eight patients with tuberculous Addison's disease, but not idiopathic patients. Thus, adrenal CT scanning could show the etiology of Addison's disease (infection or autoimmunity) and the phase of Addison's disease secondary to tuberculosis, which may be clinically important for initiating antituberculous treatment.

    Bilateral adrenal hemorrhage is an uncommon entity that is difficult to diagnose given the ambiquity of the clinical signs. Computerized tomography plays a major role in the diagnosis, disclosing enlarged adrenal glands presenting the hyperdense aspect that characterizes this disorders. We present a case of bilateral adrenal hemoorrhage in a patient diagnosed as having primary antiphospholipid antibody syndrome, which is a less common cause of adrenal hemorrhage than those classically reported, such as anticoagulant therapy, sepsis, shock and abdominal injury.

    There are many predisposing factors for neonatal adrenal haemorrhage but the causative factors are different in adults. Several cases of neonatal adrenal haemorrhage have been reported in association with renal vein thrombosis. This complication has not been documented in the adults. The presence of an adrenal mass in the setting of renal vein thrombosis should raise the possibility of adrenal haemorrhage even though this is extremely uncommon in adults.

    Ewing's sarcoma (ES) or primitive neuro-ectodermal tumor (PNET) typically occurs in long or flat bones, the chest wall, extra-skeletal soft tissue, and rarely in solid organs. Incidence of adrenal Ewing's sarcoma is very rare. Here we report a case of Ewing's sarcoma of the right adrenal gland in an 8-year-old girl who presented with an abdominal mass. The huge tumor was managed by preoperative neo-adjuvant chemotherapy followed by surgical resection. She died due to metastasis after five months of surgery.

    Congenital adrenal hyperplasia (CAH) owing to 21-hydroxylase deficiency is a monogenic disorder of adrenal steroidogenesis. To prevent genital ambiguity, in girls, prenatal dexamethasone treatment is administered early in the first trimester. Prenatal genetic diagnosis of CAH and fetal sex determination identify affected female fetuses at risk for genital virilization. Advancements in prenatal diagnosis are owing to improved understanding of the genetic basis of CAH and improved technology. Cloning of the CYP21A2 gene ushered in molecular genetic analysis as the current standard of care. Noninvasive prenatal diagnosis allows for targeted treatment and avoids unnecessary treatment of males and unaffected females. Copyright © 2016 Elsevier Inc. All rights reserved.

    Fetal adrenal developmental status is the major determinant of fetal tissue maturation and offspring growth. We have previously proposed that prenatal ethanol exposure (PEE) suppresses fetal adrenal corticosterone (CORT) synthesis. Here, we focused on PEE-induced adrenal developmental abnormalities of male offspring rats before and after birth, and aimed to explore its intrauterine programming mechanisms. A rat model of intrauterine growth retardation (IUGR) was established by PEE (4g/kg·d). In PEE fetus, increased serum CORT concentration and decreased insulin-like growth factor 1 (IGF1) concentration, with lower bodyweight and structural abnormalities as well as a decreased Ki67 expression (proliferative marker), were observed in the male fetal adrenal cortex. Adrenal glucocorticoid (GC)-metabolic activation system was enhanced while gene expression of IGF1 signaling pathway with steroidogenic acute regulatory protein (StAR), 3β-hydroxysteroid dehydrogenase (3β-HSD) was decreased. Furthermore, in the male adult offspring of PEE, serum CORT level was decreased but IGF1 was increased with partial catch-up growth, and Ki67 expression demonstrated no obvious change. Adrenal GC-metabolic activation system was inhibited, while IGF1 signaling pathway and 3β-HSD was enhanced with the steroidogenic factor 1 (SF1), and StAR was down-regulated in the adult adrenal. Based on these findings, we propose a "two-programming" mechanism for PEE-induced adrenal developmental toxicity: "the first programming" is a lower functional programming of adrenal steroidogenesis, and "the second programming" is GC-metabolic activation system-related GC-IGF1 axis programming.

    Fetal antigen 1 was purified from second trimester human amniotic fluid by immunospecific affinity chromatography followed by reversed-phase chromatography. Fetal antigen 1 is a single chain glycoprotein with a M(r) of 32-38 kDa. The amino acid composition revealed a high content of cysteines......, prolines and amino acids (aa) with acidic side-chains indicating that fetal antigen 1 is a compactly folded, strongly hydrophilic molecule. The N-terminal amino acid sequence (37 aa) revealed no homology to other known protein sequences, implying that fetal antigen 1 is a 'novel' human protein. When the aa...... sequence was back-translated into the appropriate degenerate sequence of nucleic acids, fetal antigen 1 could be partially aligned to a 'human adrenal-specific mRNA, pG2'. The indirect immunoperoxidase technique demonstrated fetal antigen 1 in fetal hepatocytes, glandular cells of fetal pancreas...

  16. Health consequences of shift work and insufficient sleep.

    Kecklund, Göran; Axelsson, John

    2016-11-01

    This review summarises the literature on shift work and its relation to insufficient sleep, chronic diseases, and accidents. It is based on 38 meta-analyses and 24 systematic reviews, with additional narrative reviews and articles used for outlining possible mechanisms by which shift work may cause accidents and adverse health. Evidence shows that the effect of shift work on sleep mainly concerns acute sleep loss in connection with night shifts and early morning shifts. A link also exists between shift work and accidents, type 2 diabetes (relative risk range 1.09-1.40), weight gain, coronary heart disease (relative risk 1.23), stroke (relative risk 1.05), and cancer (relative risk range 1.01-1.32), although the original studies showed mixed results. The relations of shift work to cardiometabolic diseases and accidents mimic those with insufficient sleep. Laboratory studies indicate that cardiometabolic stress and cognitive impairments are increased by shift work, as well as by sleep loss. Given that the health and safety consequences of shift work and insufficient sleep are very similar, they are likely to share common mechanisms. However, additional research is needed to determine whether insufficient sleep is a causal pathway for the adverse health effects associated with shift work.

    While testicular adrenal rest tumor is generally a rare intratesticular tumor, it is frequent in patients with congenital adrenal hyperplasia. The tumors are diagnosed and followed up by ultrasound examination because these tumors are non-palpable and symptomless in most cases and always benign. Ultrasound imaging features change depending on how congenital adrenal hyperplasia is controlled. We herein report three cases of testicular adrenal rest tumors with different usual and unusual imaging findings and follow-up imaging. Patient 1 was a 14-year-old boy who presented with poor compliance to medication. Patient 2 and 3 were a 10-year-old and 13-year-old boy who presented with precocious puberty and short stature, respectively. Ultrasound examinations demonstrated oval hypoechoic masses and irregular speculated hyperechoic masses in the testes and different serial imaging findings.

    This study was designed to identify novel links between lipid species and disease progression in non-alcoholic fatty liver disease (NAFLD). We analyzed lipid species in the liver and plasma of db/db mice fed a choline-deficient l-amino acid-defined, high-fat diet (CDAHFD) using liquid chromatography/mass spectrometry (LC/MS). An in vitro experiment was performed using HepG2 cells stimulated with recombinant human TNFα or IL1β. The expression of steatosis-, inflammation-, and fibrosis-related genes were analyzed. Plasma samples from NAFLD patients were also analyzed by LC/MS. The CDAHFD-fed db/db mice with hepatic steatosis, inflammation, mild fibrosis, obesity, and hypercholesterolemia displayed significantly higher hepatic and plasma levels of free adrenic acid (p < 0.05). The accumulated adrenic acid in the CDAHFD-fed db/db mice was associated with increased expression of ELOVL2 and 5, and the suppression of the acyl-CoA oxidase 1 gene during peroxisomal β-oxidation. The pretreatment of HepG2 cells with adrenic acid enhanced their cytokine-induced cytokines and chemokines mRNA expression. In NAFLD patients, the group with the highest ALT levels exhibited higher plasma adrenic acid concentrations than the other ALT groups (p-value for trend <0.001). Data obtained demonstrated that adrenic acid accumulation contributes to disease progression in NAFLD. Copyright © 2017 Elsevier Inc. All rights reserved.

    Diseases of the parathyroids, the adrenals and of neuroendocrine tumors of the pancreas are primarily diagnosed by clinical and endocrinological evaluation.The requirements concerning various imaging techniques and their relative importance in localization strategies of the different tumors are complex. Current literature search, using PubMed. Evaluation of primary hyperparathyroidism requires bone densitometry by DXA and search for nephrolithiasis by ultrasound or native CT examination.While ultrasound of the thyroid and parathyroids seems useful before any parathyroid surgery,more extensive preoperative localization strategies (sestamibi scintigraphy, MRI) should be restricted to minimal invasive parathyroid surgery or re-operations.For adrenal tumors CT and MRI are of similar diagnostic value. Imaging of pheochromocytomas should be completed by MIBG scintigraphy. Each adrenal incidentaloma requires an endocrinological work-up.A fine-needle aspiration or core needle biopsy of an adrenal tumor is rarely indicated.Before adrenal biopsy a pheochromocytoma has to be excluded.Successful localization strategies for neuroendocrine tumors of the pancreas include somatostatin receptor scintigraphy, endoscopic ultrasound and MRI.Discussion Specific localization strategies have been established for the aforementioned tumors.The continuous progress of different imaging techniques requires a regular reevaluation of these localization strategies.

    Full Text Available ABSTRACT Chronic isolation of adult animals represents a form of psychological stress that produces sympatho-adrenomedullar activation. Exercise training acts as an important modulator of sympatho-adrenomedullary system. This study aimed to investigate physical exercise-related changes in gene expression of catecholamine biosynthetic enzymes (tyrosine hydroxylase, dopamine-ß-hydroxylase and phenylethanolamine N-methyltransferase and cyclic adenosine monophosphate response element-binding (CREB in the adrenal medulla, concentrations of catecholamines and corticosterone (CORT in the plasma and the weight of adrenal glands of chronically psychosocially stressed adult rats exposed daily to 20 min treadmill running for 12 weeks. Also, we examined how additional acute immobilization stress changes the mentioned parameters. Treadmill running did not result in modulation of gene expression of catecholamine synthesizing enzymes and it decreased the level of CREB mRNA in the adrenal medulla of chronically psychosocially stressed adult rats. The potentially negative physiological adaptations after treadmill running were recorded as increased concentrations of catecholamines and decreased morning CORT concentration in the plasma, as well as the adrenal gland hypertrophy of chronically psychosocially stressed rats. The additional acute immobilization stress increases gene expression of catecholamine biosynthetic enzymes in the adrenal medulla, as well as catecholamines and CORT levels in the plasma. Treadmill exercise does not change the activity of sympatho-adrenomedullary system of chronically psychosocially stressed rats.

    The evaluation of X-CT and adrenal scintigraphy in diagnosis of Cushing syndrome and primary aldosteronism was studied in 18 patients. In Cushing syndrome, CT appearance of adenoma is commonly larger than that of primary aldosteronism and cleary deliniated by surrounding fat. So, in Cushing syndrome, diagnosis of adenoma on CT is much easier than that of primary aldosteronism, and absence of adenoma on CT suggests adrenal hyperplasia. In primary aldosteronism both of CT and scintigraphy must be performed. (author)

    The management of hereditary pheochromocytoma has drastically evolved in the last 20 years. Bilateral pheochromocytoma does not increase mortality in MEN2 or von Hippel-Lindau (VHL) mutation carriers who are followed regularly, but these mutations induce major morbidities if total bilateral adrenalectomy is performed. Cortical sparing adrenal surgery may be proposed to avoid definitive adrenal insufficiency. The surgical goal is to leave sufficient cortical tissue to avoid glucocorticoid replacement therapy. This approach was achieved by the progressive experience of minimally invasive surgery via the transperitoneal or retroperitoneal route. Cortical sparing adrenal surgery exhibits management of all patients with MEN2 or VHL hereditary pheochromocytoma. Hereditary pheochromocytoma is a rare disease, and a randomized trial comparing cortical sparing vs classical adrenalectomy is probably not possible. This lack of data most likely explains why cortical sparing surgery has not been adopted in most expert centers that perform at least 20 procedures per year for the treatment of this disease. This review examined recent data to provide insight into the technique, its indications, and the results and subsequent follow-up in the management of patients with hereditary pheochromocytoma with a special emphasis on MEN2. © 2016 European Society of Endocrinology.

    The clinical presentation of adrenal hemorrhage varies, depending on the extent of hemorrhage as well as the amount of adrenal cortex involved by the hemorrhage. We report here a case of neonatal adrenal hemorrhage revealed by late onset of neonatal jaundice. This adrenal hemorrhage most probably resulted from shoulder dystocia. The aim of this work was to focus on the fact that jaundice can be caused by adrenal hemorrhage and to emphasize the crucial importance of abdominal ultrasound in cases of persistent jaundice.

    Full Text Available Co-occurrence of adrenal incidentaloma with hypertension calls for evaluation of endocrine causes including pheochromocytoma, Cushing′s disease, and primary aldosteronism. We are reporting 40-years-old man who presented with hypertension and adrenal mass. He had elevated metanephrines, histology of resected adrenal mass revealed adrenal myelolipoma, and immuno-histochemistry was positive for chromogranin A. Both his blood pressure and urinary metanephrines returned to normal after surgery. The association of hypertension and adrenal myelolipoma may not be entirely coincidental, as it may be associated with secreting catecholamine. Literature on such an uncommon association is reviewed briefly as well.

    Cushing's disease caused by pituitary corticotroph adenoma is a common endocrine disease in dogs. A characteristic biochemical feature of corticotroph adenomas is their relative resistance to suppressive negative feedback by glucocorticoids. The abnormal expression of 11beta-hydroxysteroid dehydrogenase (11HSD), which is a cortisol metabolic enzyme, is found in human and murine corticotroph adenomas. Our recent studies demonstrated that canine corticotroph adenomas also have abnormal expression of 11HSD. 11HSD has two isoforms in dogs, 11HSD type1 (HSD11B1), which converts cortisone into active cortisol, and 11HSD type2 (HSD11B2), which converts cortisol into inactive cortisone. It has been suggested that glucocorticoid resistance in corticotroph tumors is related to the overexpression of HSD11B2. Therefore it was our aim to investigate the effects of carbenoxolone (CBX), an 11HSD inhibitor, on the healthy dog's pituitary-adrenal axis. Dogs were administered 50 mg/kg of CBX twice each day for 15 days. During CBX administration, no adverse effects were observed in any dogs. The plasma adrenocorticotropic hormone (ACTH), and serum cortisol and cortisone concentrations were significantly lower at day 7 and 15 following corticotropin releasing hormone stimulation. After completion of CBX administration, the HSD11B1 mRNA expression was higher, and HSD11B2 mRNA expression was significantly lower in the pituitaries. Moreover, proopiomelanocortin mRNA expression was lower, and the ratio of ACTH-positive cells in the anterior pituitary was also significantly lower after CBX treatment. In adrenal glands treated with CBX, HSD11B1 and HSD11B2 mRNA expression were both lower compared to normal canine adrenal glands. The results of this study suggested that CBX inhibits ACTH secretion from pituitary due to altered 11HSD expressions, and is potentially useful for the treatment of canine Cushing's disease.

    Full Text Available Placental insufficiency is associated with fetal hypoglycemia, hypoxemia, and elevated plasma norepinephrine (NE that become increasingly pronounced throughout the third trimester and contribute to intrauterine growth restriction (IUGR. This study evaluated the effect of fetal adrenal demedullation (AD on growth and pancreatic endocrine cell mass. Placental insufficiency-induced IUGR was created by exposing pregnant ewes to elevated ambient temperatures during mid-gestation. Treatment groups consisted of control and IUGR fetuses with either surgical sham or AD at 98 days gestational age (dGA; term = 147 dGA, a time-point that precedes IUGR. Samples were collected at 134 dGA. IUGR-sham fetuses were hypoxemic, hypoglycemic, and hypoinsulinemic, and values were similar in IUGR-AD fetuses. Plasma NE concentrations were ~5-fold greater in IUGR-sham compared to control-sham, control-AD, and IUGR-AD fetuses. IUGR-sham and IUGR-AD fetuses weighed less than controls. Compared to IUGR-sham fetuses, IUGR-AD fetuses weighed more and asymmetrical organ growth was absent. Pancreatic β-cell mass and α-cell mass were lower in both IUGR-sham and IUGR-AD fetuses compared to controls, however, pancreatic endocrine cell mass relative to fetal mass was lower in IUGR-AD fetuses. These findings indicate that NE, independently of hypoxemia, hypoglycemia and hypoinsulinemia, influence growth and asymmetry of growth but not pancreatic endocrine cell mass in IUGR fetuses.

    Placental insufficiency is associated with fetal hypoglycemia, hypoxemia, and elevated plasma norepinephrine (NE) that become increasingly pronounced throughout the third trimester and contribute to intrauterine growth restriction (IUGR). This study evaluated the effect of fetal adrenal demedullation (AD) on growth and pancreatic endocrine cell mass. Placental insufficiency-induced IUGR was created by exposing pregnant ewes to elevated ambient temperatures during mid-gestation. Treatment groups consisted of control and IUGR fetuses with either surgical sham or AD at 98 days gestational age (dGA; term = 147 dGA), a time-point that precedes IUGR. Samples were collected at 134 dGA. IUGR-sham fetuses were hypoxemic, hypoglycemic, and hypoinsulinemic, and values were similar in IUGR-AD fetuses. Plasma NE concentrations were ~5-fold greater in IUGR-sham compared to control-sham, control-AD, and IUGR-AD fetuses. IUGR-sham and IUGR-AD fetuses weighed less than controls. Compared to IUGR-sham fetuses, IUGR-AD fetuses weighed more and asymmetrical organ growth was absent. Pancreatic β-cell mass and α-cell mass were lower in both IUGR-sham and IUGR-AD fetuses compared to controls, however, pancreatic endocrine cell mass relative to fetal mass was lower in IUGR-AD fetuses. These findings indicate that NE, independently of hypoxemia, hypoglycemia and hypoinsulinemia, influence growth and asymmetry of growth but not pancreatic endocrine cell mass in IUGR fetuses.

    Following radiation therapy, marrow abnormalities noted on magnetic resonance imaging (MRI) are frequent and may mimic metastases. Specific radiotherapy changes are usually easily identifiable; however, traumatic lesions cause more interpretive difficulties. We assessed the incidence and MRI characteristics of insufficiency fractures in this population. During a 5-year span (1987-1991), 546 patients received pelvic radiotherapy for primary malignancies. MRI was performed in 25 of these patients at least 3 months after treatment. The mean dose in this group was 53 Gy. These MRI scans were retrospectively reviewed for the appearance of the sacrum with particular attention to the presence of insufficiency fractures. This was correlated with clinical course and scintigraphic findings. Presumed insufficiency fractures on MRI paralleled the sacral side of the sacroiliac joint, enhanced with Gd-DTPA, were most prominent or initially seen anteriorly, and had ill-defined margins on all imaging sequences. The incidence of occult sacral insufficiency fractures was at least 20%. Insufficiency fractures of the sacrum in the post-radiotherapy patient are a relatively frequent occurrence which can mimic metastases. Consideration of this phenomenon and knowledge of differential features may avoid overdiagnosis of osseous metastases. (orig.)

    Abstract The Centers for Disease Control and Prevention (CDC) in the United States has declared insufficient sleep a “public health problem.” Indeed, according to a recent CDC study, more than a third of American adults are not getting enough sleep on a regular basis. However, insufficient sleep is not exclusively a US problem, and equally concerns other industrialised countries such as the United Kingdom, Japan, Germany, or Canada. According to some evidence, the proportion of people sleeping less than the recommended hours of sleep is rising and associated with lifestyle factors related to a modern 24/7 society, such as psychosocial stress, alcohol consumption, smoking, lack of physical activity and excessive electronic media use, among others. This is alarming as insufficient sleep has been found to be associated with a range of negative health and social outcomes, including success at school and in the labour market. Over the last few decades, for example, there has been growing evidence suggesting a strong association between short sleep duration and elevated mortality risks. Given the potential adverse effects of insufficient sleep on health, well-being and productivity, the consequences of sleep-deprivation have far-reaching economic consequences. Hence, in order to raise awareness of the scale of insufficient sleep as a public-health issue, comparative quantitative figures need to be provided for policy- and decision-makers, as well as recommendations and potential solutions that can help tackling the problem.

    A solid phase radioimmunoassay for adrenal antibodies is described. In the assay plastic tubes coated with adrenal microsomes (100 μg/ml) were incubated with human sera diluted from 1:50 to 1:5000 and the retained antibodies detected by subsequent incubation with 125 I-labelled protein A. The method was precise over the range of serum dilution of 1:250 to 1:5000. In the group of 30 patients with Addison's disease 19 had positive results in adrenal antibody radioimmunoassay (RIA). Comparative studies of RIA and immunofluorescence (IFL) revealed that there was partial correlation of adrenal antibody results in patients with high titre antibodies whereas RIA usually was more sensitive than IFL in patients with low titre antibodies. Computerized tomography (CT) displayed bilateral adrenal atrophy in most patients who had adrenal antibodies. On the other hand, patients with low RIA results and negative IFL antibodies had predominantly adrenal calcifications on scans. (author)

    We evaluated the adrenals of individuals without tuberculosis (group 1 - G1) and with tuberculosis (group 2 - G2) using computed tomography. The antero-posterior length, the thickness, and the longitudinal length of the adrenals were compared in G1 and G2. The duration of the disease, the occurrence of morphologic abnormalities in G2, the distribution according to sex, age and skin color were also studied. There was difference in the antero-posterior length and thickness of right adrenal between G1 and G2. A higher prevalence of white skin male individuals was observed in G2. There was no association between duration of the disease and the occurrence of morphologic abnormalities in G2. A higher occurrence of adrenal enlargement was observed in G2. The main computed tomography findings in patients with tuberculosis were enlargement of the adrenal without calcification, enlargement of the adrenal with punctiform calcifications, and residual calcification of the adrenal.

    international scientific journals. There is considerable controversy regarding the side effects of inhaled corticosteroids. In 21 studies evaluating the effect that inhaled corticosteroids have on growth, a statistically significant reduction (growth retarded by 1-1.5 cm was observed within the first year of treatment with Beclomethasone or Budesonide inhalers. However, in studies of longer duration, no significant difference was found between final adult height and adult height of the parents. However, in ten studies of the use of inhaled corticosteroids and their effect on adrenal suppression, hypoglycemia and arrested development (no height or weight gains, as well as changes in morning serum levels and 24-h urinary levels of cortisol, were reported, especially when high doses of inhaled corticosteroids were used. Inhaled corticosteroids can reduce growth during the first year of use but do not affect adult height. However, further long-term studies are needed in order to determine the full impact of inhaled corticosteroids on final adult height. Height measures are a means of evaluating the safety and efficacy of the use of inhaled corticosteroids in children. Tests that evaluate the hypothalamic-pituitary-adrenal axis and adrenal insufficiency should be correlated with clinical symptoms and side effects.

    Radiology plays an important role in evaluating patients with suspected adrenal gland pathology. Morphologic delineation of adrenal gland is especially valuable in patients with clinical and/or biochemical evidence of a disturbance in adrenal function. Many diagnostic radiologic methods are available for demonstrating adrenal lesions. Computed tomography overcomes many of the disadvantages of these other radiologic techniques. The high degree of spatial and density resolution allows precise demonstration of the normal adrenal glands as well as detection of both small and large tumors in almost all patients. So CT of adrenal gland is an excellent noninvasive screening method and definitive imaging technique. The anthers have investigated the capability of CT to image the normal size, location and shape of both glands. Knowledge of the range of normal is useful for optimal interpretation of CT scans in patients with suspected adrenal pathology. We reviewed CT scan of 150 cases without evidence of adrenal disease. The following results were obtained; 1. There were 90 male and 60 female patients. 2. Their ages ranged from 20 to 60 years. 3. On CT, both glands were shown in 135 (90.0%), the right in 143 (95.3%), the left in 142 (94.6%). 4. In the shape of adrenal glands, most of right adrenal gland was linear or comet shaped; 68 (47.6%), most of left adrenal gland was inverted-Y shaped; 103 (72.6%). 5. In the length of adrenal glands, the right was 2.5{+-}0.77cm, the left was 2.9{+-}0.75cm. 6. In the width of adrenal glands, the right was 3.2{+-}0.74cm, the left was 2.7{+-}0.57cm. 7. In the thickness of adrenal glands, the right was 0.5{+-}0.14cm, the left was 0.6{+-}0.16cm.

    On the basis of 7 cases representing the essential types of aetiology of Cushing's syndrome, it is possible to define the value, limitations and role of adrenal scintigraphy using 131 I-19-iodocholesterol in the diagnostic investigation of hypercortisolism. The essential value of the investigation is morphological rather than functional. Adrenal scintigraphy has the same role in diagnostic investigation as various radiological procedures such as pneumoperitoneum and angiography. The latter, however, are technically difficult and fraught with risk, in contrast to the isotopic examination. The principle limitations of the method are not dosimetric but lie in the relative difficulty of interpretation of the documents obtained [fr

    This cross-sectional study was undertaken to improve our understanding of the steroidogenic alterations leading to adrenal hyperandrogenism in polycystic ovarian syndrome (PCOS). Two-hundred and thirty-four women with clinical and biochemical features suggestive of PCOS underwent metabolic and hormonal evaluation. We used the androstenedione/DHEAS ratio as a surrogate for the level of ovarian 3betaHSD activity. We then selected the 90th percentile for the ratio in those with elevated DHEAS (>9 micromol/l) as the cut-off level beyond which excess DHEAS production will be minimized by excess ovarian 3betaHSD activity. This cut-off level was at a ratio of 1.5 and all PCOS women were then divided into two groups, the higher (>1.5) being the group with excess ovarian 3betaHSD activity. We hypothesized that women with a high ratio would be unlikely to have DHEAS excess due to the rapid conversion of DHEA to androstenedione. Those with a low ratio (concordant ovarian and adrenal steroidogenesis) could then either have high DHEAS or normal DHEAS, depending on whether CYP17 activity was higher or lower respectively. Insulin resistance was found to be associated with decreased CYP17 activity while irregular cycles and neuroendocrine dysfunction were determined to be associated with higher ovarian 3betaHSD activity. Adrenal androgen excess in PCOS seems to be related to insulin sensitivity as well as decreased activity of 3betaHSD, the latter being preferentially present in those women with regular cycles or without neuroendocrine dysfunction.

    Congenital adrenal hypoplasia, an X-linked disorder, is characterized by primary adrenal insufficiency and frequent association with hypogonadotropic hypogonadism. The X-chromosome gene DAX-1 has been most recently identified and shown to be responsible for this disorder. We analyzed the DAX-1 genes of two unrelated Japanese patients with congenital adrenal hypoplasia and hypogonadotropic hypogonadism by using PCR amplification of genomic DNA and its complete exonic sequencing. In a family containing several affected individuals, the proband male patient had a stop codon (TGA) in place of tryptophan (TGG) at amino acid position 171. As expected, his mother was a heterozygous carrier for the mutation, whereas his father and unaffected brother did not carry this mutation. In another male patient with noncontributory family history, sequencing revealed a 1-bp (T) deletion at amino acid position 280, leading to a frame shift and, subsequently a premature stop codon at amino acid position 371. The presence of this mutation in the patients` genome was further confirmed by digestion of genomic PCR product with MspI created by this mutation. Family studies using MspI digestion of genomic PCR products revealed that neither parent of this individual carried the mutation. These results clearly indicate that congenital adrenal hypoplasia and hypogonadotropic hypogonadism result from not only inherited but also de novo mutation in the DAX-1 gene. 31 refs., 4 figs., 2 tabs.

    Insufficient sleep poses an important and complicated set of health risks in the adolescent population. Not only is deficient sleep (defined as both sleep duration inadequate to meet sleep needs and sleep timing misaligned with the body's circadian rhythms) at epidemic levels in this population, but the contributing factors are both complex and numerous and there are a myriad of negative physical and mental health, safety and performance consequences. Causes of inadequate sleep identified in this population include internal biological processes such as the normal shift (delay) in circadian rhythm that occurs in association with puberty and a developmentally-based slowing of the "sleep drive", and external factors including extracurricular activities, excessive homework load, evening use of electronic media, caffeine intake and early school start times. Consequences range from inattentiveness, reduction in executive functioning and poor academic performance to increased risk of obesity and cardio-metabolic dysfunction, mood disturbances which include increased suicidal ideation, a higher risk of engaging in health risk behaviors such as alcohol and substance use, and increased rates of car crashes, occupational injuries and sports-related injuries. In response to these concerns, a number of promising measures have been proposed to reduce the burden of adolescent sleep loss, including healthy sleep education for students and families, and later school start times to allow adolescents to obtain sufficient and appropriately-timed sleep.

    To examine whether exposure to workplace stressors predicts changes in physical activity and the risk of insufficient physical activity. Prospective data from the Finnish Public Sector Study. Repeated exposure to low job control, high job demands, low effort, low rewards and compositions of these (job strain and effort-reward imbalance) were assessed at Time 1 (2000-2002) and Time 2 (2004). Insufficient physical activity (workplace stressors on change in physical activity was examined using fixed-effects (within-subject) logistic regression models (N=6665). In addition, logistic regression analysis was applied to examine the associations between repeated exposure to workplace stressors and insufficient physical activity (N=13 976). In these analyses, coworker assessed workplace stressor scores were used in addition to individual level scores. The proportion of participants with insufficient physical activity was 24% at baseline and 26% at follow-up. 19% of the participants who were sufficiently active at baseline became insufficiently active at follow-up. In the fixed-effect analysis, an increase in workplace stress was weakly related to an increase in physical inactivity within an individual. In between-subjects analysis, employees with repeated exposure to low job control and low rewards were more likely to be insufficiently active at follow-up than those with no reports of these stressors; fully adjusted ORs ranged from 1.11 (95% CI 1.00 to 1.24) to 1.21 (95% CI 1.05 to 1.39). Workplace stress is associated with a slightly increased risk of physical inactivity.

    Phaeochromocytoma localisation is generally reliably achieved with modern imaging techniques, particularly in sporadic cases. On occasion, however, there can be diagnostic doubt due to the presence of bilateral adrenal abnormalities, particularly in patients with mutations in genes predisposing them to the development of multiple phaeochromocytomas. In such cases, surgical intervention is ideally limited to large or functional lesions due to the long-term consequences associated with hypoadrenalism. Adrenal venous sampling (AVS) for catecholamines has been used in this situation to guide surgery, although there are few data available to support diagnostic thresholds. Retrospective analyses of AVS results from 2 centres were carried out. A total of 172 patients (88 men, 84 women) underwent AVS under cosyntropin stimulation for the diagnosis of established primary aldosteronism (PA) with measurement of adrenal and peripheral venous cortisol, aldosterone and catecholamines. Six patients (3 men, 3 women) with phaeochromocytoma underwent AVS for diagnostic purposes with subsequent histological confirmation. Reference intervals for the adrenal venous norepinephrine to epinephrine ratio were created from the PA group. Using the 97.5th centile (1.21 on the left, 1.04 on the right), the false negative rate in the phaeochromocytoma group was 0%. In conclusion, this study describes the largest dataset of adrenal venous catecholamine measurements and provides reference intervals in patients without phaeochromocytoma. This strengthens the certainty with which conclusions related to adrenal venous sampling for catecholamines can be drawn, acknowledging the procedure is not part of the routine diagnostic workup and is an adjunct for use only in difficult clinical cases. © Georg Thieme Verlag KG Stuttgart · New York.

    Full Text Available Background: In humans, the adrenal glands and gonads undergo distinct biological events between 6-10 weeks post conception (wpc, such as testis determination, the onset of steroidogenesis and primordial germ cell development. However, relatively little is currently known about the genetic mechanisms underlying these processes. We therefore aimed to generate a detailed genomic atlas of adrenal and gonad development across these critical stages of human embryonic and fetal development. Methods: RNA was extracted from 53 tissue samples between 6-10 wpc (adrenal, testis, ovary and control. Affymetrix array analysis was performed and differential gene expression was analysed using Bioconductor. A mathematical model was constructed to investigate time-series changes across the dataset. Pathway analysis was performed using ClueGo and cellular localisation of novel factors confirmed using immunohistochemistry. Results: Using this approach, we have identified novel components of adrenal development (e.g. ASB4, NPR3 and confirmed the role of SRY as the main human testis-determining gene. By mathematical modelling time-series data we have found new genes up-regulated with SOX9 in the testis (e.g. CITED1, which may represent components of the testis development pathway. We have shown that testicular steroidogenesis has a distinct onset at around 8 wpc and identified potential novel components in adrenal and testicular steroidogenesis (e.g. MGARP, FOXO4, MAP3K15, GRAMD1B, RMND2, as well as testis biomarkers (e.g. SCUBE1. We have also shown that the developing human ovary expresses distinct subsets of genes (e.g. OR10G9, OR4D5, but enrichment for established biological pathways is limited. Conclusion: This genomic atlas is revealing important novel aspects of human development and new candidate genes for adrenal and reproductive disorders.

    Fetal glucocorticoid excess programs a range of detrimental outcomes in the adult phenotype, at least some of which may be due to altered adult adrenocortical function. In this study, we determined the effects of maternal dexamethasone treatment on offspring adrenal morphology and function, as well as the interactive effects of postnatal dietary omega-3 (n-3) fatty acids. This postnatal dietary intervention has been shown to alleviate many of the programming outcomes in this model, but whether this is via the effects on adrenal function is unknown. Dexamethasone acetate was administered to pregnant rats (0.75 microg/ml drinking water) from day 13 to term. Cross-fostered offspring were raised on either a standard or high-n-3 diet. Adrenal weight (relative to body weight) at 6 months of age was unaffected by prenatal dexamethasone, regardless of postnatal diet, and stereological analysis showed no effect of dexamethasone on the volumes of adrenal components (zona glomerulosa, zona fasciculata/reticularis or adrenal medulla). Expression of key steroidogenic genes (Cyp11a1 and Star) was unaffected by either prenatal dexamethasone or postnatal diet. In contrast, adrenal expression of Mc2r mRNA, which encodes the ACTH receptor, was higher in offspring of dexamethasone-treated mothers, an effect partially attenuated by the Hn3 diet. Moreover, stress-induced levels of plasma and urinary corticosterone and urinary aldosterone were elevated in offspring of dexamethasone-treated mothers, indicative of enhanced adrenal responsiveness. In conclusion, this study shows that prenatal exposure to dexamethasone does not increase basal adrenocortical activity but does result in a more stress-responsive adrenal phenotype, possibly via increased Mc2r expression.

    Steroid hormones synthesized from cholesterol in the fetal adrenal are crucial for fetal development. We have observed the inhibited fetal adrenal corticosterone synthesis and increased intrauterine growth retardation (IUGR) rate in rats under prenatal caffeine ingestion. The aim of this study is to evaluate the effects of prenatal caffeine ingestion on cholesterol supply in fetal adrenal steroidogenesis in rats and explore the underlying epigenetic mechanisms. Pregnant Wistar rats were treated with 60 mg/kg·d caffeine from gestational day (GD) 7 to GD17. Histological changes of fetal adrenals and increased IUGR rates were observed in the caffeine group. There were significantly decreased steroid hormone contents and cholesterol supply in caffeine-treated fetal adrenals. Data from the gene expression array suggested that prenatal caffeine ingestion caused increased expression of genes related to DNA methylation and decreased expression of genes related to cholesterol uptake. The following conjoint analysis of DNA methylation array with these differentially expressed genes suggested that scavenger receptor class B type I (SR-BI) may play an important role in caffeine-induced cholesterol supply deficiency. Moreover, real-time RT-PCR and immunohistochemical detection certified the inhibitory effects of caffeine on both mRNA expression and protein expression of SR-BI in the fetal adrenal. And the increased DNA methylation frequency in the proximal promoter of SR-BI was confirmed by bisulfite-sequencing PCR. In conclusion, prenatal caffeine ingestion can induce DNA hypermethylation of the SR-BI promoter in the rat fetal adrenal. These effects may lead to decreased SR-BI expression and cholesterol uptake, which inhibits steroidogenesis in the fetal adrenal. - Highlights: • Prenatal caffeine ingestion inhibits steroid hormone production in the fetal adrenal. • Prenatal caffeine ingestion inhibits cholesterol uptake in the fetal adrenal. • Prenatal caffeine

Data from the gene expression array suggested that prenatal caffeine ingestion caused increased expression of genes related to DNA methylation and decreased expression of genes related to cholesterol uptake. The following conjoint analysis of DNA methylation array with these differentially expressed genes suggested that scavenger receptor class B type I (SR-BI) may play an important role in caffeine-induced cholesterol supply deficiency. Moreover, real-time RT-PCR and immunohistochemical detection certified the inhibitory effects of caffeine on both mRNA expression and protein expression of SR-BI in the fetal adrenal. And the increased DNA methylation frequency in the proximal promoter of SR-BI was confirmed by bisulfite-sequencing PCR. In conclusion, prenatal caffeine ingestion can induce DNA hypermethylation of the SR-BI promoter in the rat fetal adrenal. These effects may lead to decreased SR-BI expression and cholesterol uptake, which inhibits steroidogenesis in the fetal adrenal. - Highlights: • Prenatal caffeine ingestion inhibits steroid hormone production in the fetal adrenal. • Prenatal caffeine ingestion inhibits cholesterol uptake in the fetal adrenal. • Prenatal caffeine

    For diagnosis of adenomas in primary aldosteronism CT proved to be helpful. Although microadenomas have to be ruled out by selective venous sampling from both adrenal glands adenomas down to 8 mm in diameter can be visualized. Scintigraphy does not always permit reliable differentiation of unilateral adenoma from bilateral hyperplasia. - In endogenous Cushing's syndrome adrenal carcinomas are underlying etiologically in about 10% of the cases. Since carcinomas are detected easily by CT it should be performed in the first place. Whereas adenomas and hyperplasia are easily diagnosed by scintigraphy carcinomas may escape scintigraphy. - Pheochromocytomas, if situated in the vicinity of the kidneys, can be localiced safely by CT. Contrary to adenomas, carcinomas and pheochromocytomas may be detected by CT without difficulty because of their size. (orig.) [de

    administration, a significant cortisol peak was detected in patients and controls, whereas no significant difference in cortisol area-under-the-curve (AUC) was found between the groups. In contrast, ACTH induced a significantly higher (p < 0.05) peak of 17-OHP and AUC in PMR patients than in controls. This study found reduced production of adrenal hormones (cortisol, DHEAS) at baseline in patients with active and untreated PMR. The defect seems mainly related to altered adrenal responsiveness to the ACTH stimulation (i.e., increased 17-OHP), at least in untreated patients. The 12 month glucocorticoid treatment of patients reduced the production of inflammatory mediators (i.e., IL-6) in a stable manner that persisted after glucocorticoids were tapered.

    131 I-Adosterol (6β-iodomethyl-19-norcholest-5(10)-3β-ol) was administered to evaluate adrenal grand in 20 patients including 9 patients with primary aldosteronism, 5 with Cushing's syndrome, one with pheochromocytoma, one with retroperitoneal tumor, 3 with essential hypertension and one with obesity. Standard scintigraphies were performed at 3rd day and again 6th day after administration of 131 I-adosterol (1-1.5 mCi). Suppression scintigraphies were obtained while the patients were taking dexamethasone 2 to 3 mg daily from 3 days prior to injection of the tracer until adrenal imaging. In the cases with essential hypertension and obesity, both adrenal glands were delineated equally by standard scintigraphy, and in one patient, undergone suppression scintigraphy, the uptake of 131 I-adosterol by both glands were completely inhibited by dexamethasone administration. In primary aldosteronism, six of the 9 patients demonstrated the increased radioactivity in one side, and were diagnosed as aldosteronoma. In 3 cases, failed to show the lesions on standard scintigraphy, the lesions could be detected by suppression scintigraphy, and aldosteronomas measuring 1 x 1 x 0.7, 2 x 2 x 1 and 1.7 x 1.5 x 0.8 cm were confirmed by operation. In Cushing's syndrome, standard scintigraphy could easily distinguish between adenoma (one case) and bilateral hyperplasia (4 cases). Adrenal scintigraphy was also a useful method in order to assess the effect of pituitary irradiation therapy in the case of hyperplasia. In pheochromocytoma and retroperitoneal tumor, the side of the lesion was identified by the absence of a functioning gland. Suppression scintigraphy was particularly useful in detecting the localization of the small tumor in primary aldosteronism. (auth.)

    An 11-year-old spayed female pit bull terrier was presented with a 2-month history of polyuria, polydipsia, polyphagia, and panting. Serum chemistry, blood and urine analysis, and tests for hyperadrenocorticism suggested an adrenal tumor. Abdominal ultrasound identified a mass caudal to the right kidney. The mass was completely excised and histopathology was consistent with endocrine carcinoma. Three years later there was no evidence of recurrence or metastasis.

    Due to its high tissue contrast and multiplanar imaging capabilites, MRI provides a detailed display of renal and adrenal anatomy. Recent technical developments overcoming the problem of respiration induced motion artifacts and the use of paramagnetic contrast agents have further improved the performance of MRI which has now evolved as an alternative or complementary imaging modality to ultrasound, excretory urography and computed tomography. Dynamic contrast-enhanced studies will usually allow to detect even small enhancing solid areas within the cyst wall. Use of a fast (turbo) spoiled gradient echo sequence allows for assessment of contrast enhancement dynamics in renal and adrenal masses. For tumor staging, the multiplanar imaging capabilities of MRI are advantageous. Perinephric extent is best detected using opposed-phase GRE images resulting in an artifical accentuation of renal contours. Extension into venous structures is best diagnosed by using a GRE sequence allowing for distinction between flowing blood and tumor thrombus. Noninvasive differentiation of adrenal lesions can be performed with an unprecedented accuracy using chemical-shift imaging. (orig.)

    The interrenal and medullary cords as well as the blood vessels and connective tissue proportions in the adrenal glands of the male Nigerian fowl (Gallus domesticus) and guinea-fowl (Numida meleagris) were studied by microstereological techniques. Laying domestic fowl of the Rhode Island Red breed were entirely defeathered and maintained in a hot, humid pen for a period of three months, after which the adrenal glands were also studied microstereologically. Interrenal cord width was also measured in all the birds studied. The interrenal cords of the subscapular zone were consistently wider than those cords in the inner zone of the adrenal glands. This clearly suggested morphological zoning. The proportion of interrenal tissue was significantly greater in the guinea-fowl than in the Nigerian fowl, but the medullary tissue and the blood vessels and connective tissue were not significantly different. Interrenal hypoplasia or medullary hyperplasia occurred in the defeathered Rhode Island Red fowl as compared to the control birds of the same breed and sex. The significance of these findings is discussed. PMID:7440402

    Full Text Available Introduction. Adrenal hemangioma is a rare disease, with only some 60 cases reported previously. Due to the difficulty of the preoperative diagnosis of adrenal hemangioma, almost all of the cases were diagnosed by a histopathological analysis of surgical specimens. Case Presentation. A 52-year-old man was referred to our department for further examination of his left retroperitoneal tumor. He had received hemodialysis due to chronic renal failure resulting from membranous nephropathy. Computed tomography revealed a mass around his left hilum. Magnetic resonance imaging (MRI and positron-emission tomography (PET-CT were unable to confirm or deny malignancy, and tumor markers, including CEA and CA19-9, showed slight elevation. His tumor grew from 38 mm to 54 mm in diameter in 7 months of follow-up. We therefore planned retroperitoneal tumor resection with left nephrectomy. Histopathologically, hyperplastic small vessels with hemorrhaging and denaturation were seen. The endothelial cells showed no variants or division of the nucleus. Based on this diagnosis, no further therapy was performed. He has had no recurrence in the eight months since the surgery. Conclusion. We herein report a rare case of adrenal hemangioma.

    Although its unparalleled tissue contrast resolution and multiplanar imaging capability, and the fact that it does not require exogeneous contrast agents, allow very detailed anatomic delineation of retroperitoneal anatomy in a safe and completely noninvasive fashion, magnetic resonance imaging (MRI) cannot at this time be used a screening procedure for evaluation of the adrenal glands and kidneys. At present, MRI remains time-consuming and expensive when compared with conventional X-ray computed tomography (X-ray CT), sonography, and quantitative scintigraphy. It is recommended, rather, that MRI can be reserved for situations in which its particular advantages can be expected to resolve questions raised by other imaging modalities. For example, MRI can be used t characterize an adrenal mass detected by CT, to evaluate extension of renal or adrenal neoplasms into adjacent organs when CT findings are equivocal, to assess vascular patency when intravenous contrast material is contraindicated or CT findings are equivocal, and to evaluate the cause of renal allograft failure when findings with other radiologic modalities are inconclusive and biopsy is medically contraindicated. Evaluation of the cause of ureteral obstruction and detection of calculi or lesional calcification are more reliably achieved with CT

    Full Text Available Checkpoint inhibitors, such as ipilimumab and pembrolizumab, have transformed the prognosis for patients with advanced malignant melanoma and squamous non-small-cell lung cancer, and their use will only expand as experience is gained in a variety of other malignancies, for instance, renal and lymphoma. As the use of checkpoint inhibitors increases, so too will the incidence of their unique side effects, termed immune-related adverse events (irAEs, which can affect dermatological, gastrointestinal, hepatic, endocrine and other systems. Nivolumab is a monoclonal antibody that blocks the human programmed death receptor-1 ligand (PD-L1 found on many cancer cells and is licensed for the treatment of advanced malignant melanoma. We describe the first case of nivolumab-induced adrenalitis resulting in primary adrenal failure presenting with hyponatraemia in a 43-year-old man with malignant melanoma. The case highlights the potentially life-threatening complications of checkpoint inhibitors and the need for patient education and awareness of irAEs among the wider clinical community because such side effects require prompt recognition and treatment.

    The sonographic detection of adrenal masses in patients with neoplasms, especially neoplasms of the lung, can be related to the presence of both metastases and adenomas. In order to assess the benign/malignant nature of the such lesions, the adrenal glands of 43 patients with neoplasms (36 of them lung cancers) were studied with sonography (US) and fine needle aspiration biopsy (FNAB): in all, 58 masses were seen (28 monolateral and 15 bilateral). Six lesions (13%) presented with cytological features of benignancy, and on US they appeared as hypoechoic (as compared to the liver), round masses, with regular margins, ranging in size from 1.2 cm to 3.4 cm (average: 2.6 cm). In the remaining 34 patients (80%), cellular material with features of malignancy was obtained with FNAB. The US appearence of these metastases was heterogenous, with the same echogenicity as the liver, and average size >3 cm. On the basis of data obtained, the limit of 3 cm (if we consider the average dimension), corresponds to the threshold of benignancy, as well as the monolateral and hypoechoic appearence of the lesion. To sum up, the use of FNAB should be limited to those lesions which present with typical adenomatous features and for borderline lesions, while the diagnosis of metastases is sufficiently accurate (p 3 cm

  9. The controversy on chronic cerebrospinal venous insufficiency

    2013-08-01

    Full Text Available The objective of this review is to analyze the actual scientific controversy on chronic cerebrospinal venous insufficiency (CCSVI and its association with both neurodegenerative disorders and multiple sclerosis (MS. We revised all published studies on prevalence of CCSVI in MS patients, including ultrasound and catheter venography series. Furthermore, we take into consideration other publications dealing with the pathophysiologic consequences of CCSVI in the brain, as well as ecent data characterizing the pathology of the venous wall in course of CCSVI. Finally, safety and pilot data on effectiveness of endovascular CCSVI treatment were further updated. Studies of prevalence show a big variability in prevalence of CCSVI in MS patients assessed by established ultrasonographic criteria. This could be related to high operator dependency of ultrasound. However, 12 studies, by the means of more objective catheter venography, show a prevalence >90% of CCSVI in MS. Global hypo-hypoperfusion of the brain, and reduced cerebral spinal fluid dynamics in MS was shown to be related to CCSVI. Postmortem studies and histology corroborate the 2009 International Union of Phlebology (UIP Consensus decision to insert CCSVI among venous malformations. Finally, safety of balloon angioplasty of the extracranial veins was certainly demonstrated, while prospective data on the potential effectiveness of endovascular treatment of CCSVI support to increase the level of evidence by proceeding with a randomized control trial (RCT. Taking into account the current epidemiological data, including studies on catheter venography, the autoptic findings, and the relationship between CCSVI and both hypo-perfusion and cerebro-spinal fluid flow, we conclude that CCSVI can be definitively inserted among the medical entities. Research is still inconclusive in elucidating the CCSVI role in the pathogenesis of neurological disorders. The controversy between the vascular and the

    This account of techniques, range of indications and results of percutaneous adrenal biopsy refers to communications in the literature and to the authors' own experience. Lateral, transhepatic aspiration of adrenal material guided by sonographic control is more easy in the right adrenal gland. Punctation of the left adrenal gland ought to be done from the back and guided by computerized tomography, also in order to leave spleen, kidney, pancreas and stomach as unaffected as possible. The most frequent problem indicating adrenal biopsy still is differentiation between metastases or encretorily non-active adenomas in tumor patients. Experienced examiners will achieve an 80 to 90% sensitivity of adrenal biopsy. Clinically established, suspected phaeochromocytoma is an absolute contra-indication to fine-needle biopsy.

    Rubio-Puchol, O; Garzón-Pastor, S; Salom-Vendrell, C; Hernández-Mijares, A

    Unilateral adrenal hyperplasia is a rare cause of primary hyperaldosteronism (around a 3%) that has surgical treatment. A case of a patient with hypertension resistant to conventional therapy in treatment with 7 drugs who presented with primary hyperaldosteronism due to unilateral adrenal hyperplasia is presented. A left adrenalectomy was performed, and the patient had a good clinical response, with no need of any drug after 2 years of surgery. Unilateral adrenal hyperplasia is a different entity and it is not an asymmetric variant of the bilateral adrenal hyperplasia. In the study of patients with primary hyperaldosteronism and imaging tests with absence of adenoma is a diagnosis that must be considered before cataloguing patients with bilateral adrenal hyperplasia and start a medical treatment, because unilateral adrenal hyperplasia would have a surgical resolution.

    The first synthesis of 131 I-19-iodocholesterol had a 10 to 25 percent radiochemical impurity that was not iodide ion. This impurity has been identified as 6β- 131 I-iodomethyl-19-nor cholest-5(10)-en-3β-ol (NP-59) and has been synthesized. Tissue distribution studies with 131 I-NP-59 in rats and dogs revealed a higher adrenal uptake and adrenal-to-tissue ratios compared to 131 I 19-iodocholesterol, probably less in vivo deiodination, and superior adrenal images. A high uptake was seen in the adrenal medulla in addition to that in the cortex. Iodine-131-NP-59 is being evaluated for the early detection of adrenal--cortical disorders and as a potential scanning agent for detecting structural abnormalities of the adrenal medulla

    Congenital adrenal hyperplasia due to 21-hydroxylase deficiency is an autosomal recessive disorder caused by mutations in the CYP21A2 gene. Cortisol and aldosterone synthesis are impaired in the classic forms (adrenal insufficiency and salt-wasting crisis). Females affected are virilised at birth, and are at risk for genital ambiguity. In this article we give recommendations for an early as possible diagnosis and an appropriate and individualised treatment. A patient and family genetic study is essential for the diagnosis of the patient, and allows genetic counselling, as well as a prenatal diagnosis and treatment for future pregnancy.

    1987-07-01

    Investigations into the effects of culturing bovine adrenal chromaffin cells in the presence (72 h) of dibutyryl cyclic AMP, forskolin, and reserpine on the level and release of [Met]enkephalyl-Arg6-Phe7 immunoreactivity, noradrenaline, and adrenaline are reported. The assay for [Met]enkephalyl-Arg6-Phe7 immunoreactivity recognises both peptide B, the 31-amino acid carboxy-terminal segment of proenkephalin, and its heptapeptide fragment, [Met]enkephalyl-Arg6-Phe7. Treatments that elevate cyclic AMP increase the amount of peptide immunoreactivity in these cells; this is predominantly peptide B-like immunoreactivity in both control cells and cyclic AMP-elevated cells. Treatment with reserpine gives no change in total immunoreactivity levels, but does not result in increased accumulation of the heptapeptide [Met]enkephalyl-Arg6-Phe7 at the expense of immunoreactivity that elutes with its immediate precursor, peptide B. Cyclic AMP treatment causes either no change or a decrease in levels of accumulated noradrenaline and adrenaline. However, the release of [Met]enkephalin-Arg6-Phe7 immunoreactivity, noradrenaline, and adrenaline is increased by 72-h pretreatment with forskolin or dibutyryl cyclic AMP, whether release is stimulated by nicotine or elevated potassium. In each case the molecular form of [Met]enkephalyl-Arg6-Phe7 immunoreactivity that is released approximately reflects the cell content. Pretreatment with reserpine has no effect on the total [Met]enkephalyl-Arg6-Phe7 immunoreactivity released, but does result in an increased release of the heptapeptide and a decrease in release of peptide B-like immunoreactivity. The studies suggest that the levels of [Met]enkephalyl-Arg6-Phe7 and peptide B available for release are controlled both at the level of proenkephalin synthesis and at the level of double-basic residue proteolysis.

    From June 1977 through June 1980, sixty-one patients who were suspected to have adrenal diseases were examined with a CT scanner at Tokyo Women's Medical College. They consist of twenty five primary hyperaldosteronism, eight Cushing's syndrome, twenty pheochromocytoma and eight other adrenal masses. Ten patients were unexpectedly found to have adrenal lesion or mass simulating an adrenal tumor on CT performed for other reasons. CT findings were reviewed and correlated with surgical findings, postmortem studies and with results of other diagnostic modalities. 1. Primary hyperaldosteronism. Fifteen of twenty-five patients underwent surgery. Thirteen were pathologically proved to have aldosteronoma and two hyperplasia. Ten of thirteen patients with aldosteronoma were correctly diagnosed by CT scan. 2. Cushing's syndrome. Unilateral adenoma was correctly diagnosed preoperatively by CT scan on two surgically proved cases. CT showed marked enlargement of the adrenal gland with multiple nodules measuring less than 2 cm in diameter in the patient with nodular hyperplasia. Four patients were found to have normal-appearing adrenals with CT scan. 3. Pheochromocytoma. Three adrenal and one juxta-adrenal pheochromocytomas were detected by CT scan. Pheochromocytoma was considered as very unlikely on the basis of CT scan as well as further clinical investigation in sixteen patients. The value of CT scan for localization of extraadrenal pheochromocytoma remains established. 4. Miscellaneous adrenal disease and extra-adrenal masses simulating adrenal lesions. Two primary carcinoma, two bilateral metastasis, two adrenal neuroblastoma and a cyst were detected by CT scan. In cases with a huge mass, however, the origin and histologic diagnosis could not always be determined by CT scan. (author)

    Abstract : Cancer patients experience weight loss for a variety of reasons, commencing with the tumor's metabolism (Warburg effect) and proceeding via cachexia to loss of appetite. In pancreatic cancer, several other factors are involved, including a loss of appetite with a particular aversion to meat and the incapacity of the pancreatic gland to function normally when a tumor is present in the pancreatic head. Pancreatic exocrine insufficiency is characterized by a deficiency of the enzymes secreted from the pancreas due to the obstructive tumor, resulting in maldigestion. This, in turn, contributes to malnutrition, specifically a lack of fat-soluble vitamins, antioxidants, and other micronutrients. Patients with pancreatic cancer and pancreatic exocrine insufficiency have, overall, an extremely poor prognosis with regard to surgical outcome and overall survival. Therefore, it is crucial to be aware of the mechanisms involved in the disease, to be able to diagnose pancreatic exocrine insufficiency early on, and to treat malnutrition appropriately, for example, with pancreatic enzymes.

    In 15 cases with adrenal lesion, we studied the clinical usefulness of computed tomography (CT) and scintigram. CT and RI have been successfully to locate adrenal funtioning cortical tumors (6/6) as small as 10 mm in diameter. In 5 adrenal non-funtioning cortical and medullary disorders, RI finding only shows RI activity is decreasing, but CT may be helpful in differential diagnosis. At present, CT is a reliable technique for locating adrenal disorders, and we should suggest that it should be the initial radiographic investigation. (author)

    Adrenal imaging in the past has been limited in its clinical application by the long interval between administration of dose and visualization of adrenal glands. We review our experience with the use of a newer labeling agent, NP-59, in 29 patients with various adrenal disorders and in 4 normal subjects. With this agent, identification of adrenal lesions is possible with a high degree of accuracy, and diagnostic information is usually available within 48 hrs. NP-59 is particularly useful in evaluating primary aldosteronism and selected cases of Cushing's syndrome

    Kidneys are the main route of elimination for many antineoplastic drugs and their metabolites. The kidney dysfunction may lead to the drug cumulation in organism with the resulting increased systemic toxicity. A lot of used cytostatics requires a dose modification at different levels of renal insufficiency. Due to the lack of data from clinical trials, the limiting of systemic toxicity is difficult especially in patients with severe renal impairment or patients undergoing chronic hemodialysis. The following article is focused on the preventive strategies dealing with recommended dosing modification of various antineoplastic agents in patients with renal insufficiency. (author)

    In 222 patients the adrenal glands were examined in detail by arteriography and venography, and if indicated also the ovaries, kidneys, bladder and other organs were checked up. Blood samples were taken from the adrenal glands, renal veins and the vena cava inferior in the bifurcational and subdiaphragmatic region. According to the clinical requirements cortisol, corticotropine, aldosterone, adrenaline, noradrenaline and renine activity were determined. Comprehensive angiographic and radioimmunologic studies revealed in 54 patients tumors of the adrenal cortex. Tumors of the adrenal medulla were detected in 43 of the cases. In 103 cases a morbus Icenko-Cushing was found. The basic examination of the diagnostic schedule was selective adrenal venography. Adrenal arteriography and measurement of venous hormone levels were complementary investigations and were rarely used as independent methods. (author)

    How anti-Müllerian hormone (AMH) and testosterone (T) interrelate in infertile women is currently largely unknown. We, therefore, in a retrospective cohort study investigated how infertile women with high-AMH (AMH ≥75th quantile; n=144) and with normal-AMH (25th-75th quantile; n=313), stratified for low-T (total testosterone ≤19.0ng/dL), normal-T (19.0-29.0ng/dL) and high-T (>29.0ng/dL) phenotypically behaved. Patient age, follicle stimulating hormone (FSH), dehyroepiandrosterone (DHEA), DHEA sulphate (DHEAS), cortisol (C), adrenocorticotrophic hormone (ACTH), IVF outcomes, as well as inflammatory and immune panels were then compared between groups, with AMH and T as variables. We identified a previously unknown infertile PCOS-like phenotype, characterized by high-AMH but, atypically, low-T, with predisposition toward autoimmunity. It presents with incompatible high-AMH and low-T (lean PCOS-like patients, presenting delayed for tertiary fertility services. Since also characterized by low DHEAS, low-T is likely of adrenal origina, and consequence of autoimmune adrenal insufficiency since also accompanied by low-C and evidence of autoimmunity. DHEA supplementation in such patients equalizes low- to normal-T and normalizes IVF cycle outcomes. Once recognized, this high-AMH/low-T phenotype is surprisingly common in tertiary fertility centers but, currently, goes unrecognized. Its likely adrenal autoimmune etiology offers interesting new directions for investigations of adrenals control over ovarian function via adrenal androgen production. Copyright © 2016 Elsevier Ltd.

    Full Text Available Background: The adrenal gland is not spared from the involvement by tuberculosis. One of the recognized causes of adrenal insufficiency (AI is tuberculosis. AI, mostly at the subclinical level, is common in persons with pulmonary tuberculosis (PTB infection, occurring in about 23% of patients. Coinfection with PTB and human immunodeficiency virus (HIV may compromise adrenocortical function and produce significant adrenocortical insufficiency. Objective: To determine if coinfection with tuberculosis and HIV have a compound effect on adrenocortical function in persons with HIV and PTB coinfection. Materials and Methods: Persons with sputum-positive PTB, treatment naive, who met our inclusion criteria, were selected. All the recruited patients were screened for HIV and those positive for HIV infection had confirmatory test. A baseline blood samples for cortisol, fasting plasma glucose, full blood count, and electrolytes were collected between 8.00 h and 9.00 h immediately before administration of adrenocorticotropic hormone (ACTH. The persons received an intravenous bolus injection of 1 μg ACTH (Alliance Pharmaceuticals Ltd., Chippenham, Wiltshire SN15 2BB and blood sample was drawn for cortisol level at 30 min. Results: Forty-four people with PTB infection and forty people with PTB and HIV coinfection met the inclusion criteria of the study. The adrenal response to 1 μg ACTH stimulation in participants with PTB and PTB and HIV coinfection showed that the mean basal cortisol level in the 2 groups was not statistically significant; however, 30-min post-ACTH stimulation cortisol level was 630.84 ± 372.17 and 980.36 ± 344.82 nmol/L (P < 0.001 and increment was 367.79 ± 334.87 and 740.77 ± 317.97 nmol/L (P < 0.001, respectively. Fourteen persons (31.8% with PTB has subnormal adrenal response to ACTH stimulation while only 2 (5% persons with PTB and HIV coinfection has subnormal response. Conclusion: AI, at subclinical level, was less frequent in

    The aim of this study was to increase awareness of, and to show the variable clinical and radiological features of, subchondral insufficiency fractures of the femoral head. The clinical and radiological findings in 7 patients with subchondral insufficiency fractures of the femoral head were reviewed retrospectively. The diagnosis was confirmed histologically in 4 patients. Radiographs were performed in all patients, MRI in 5 and scintigraphy in 4 patients. Radiographs showed varying degrees of femoral head collapse in 4 patients. In the remaining 3 patients radiographs showed a normal femoral head, regional osteoporosis and focal sclerosis, respectively. Magnetic resonance imaging showed a low-signal band on T1- and T2-weighted images in the subchondral bone adjacent or parallel to the articular surface associated with bone marrow oedema. Scintigraphy showed increased uptake in the femoral head. Insufficiency fractures of the femoral head are easily overlooked or confused with avascular necrosis and, when there is significant joint destruction, osteoarthritis. Unsuspected insufficiency fracture of the femoral head can lead to significant and rapid loss of bone stock in osteoporotic patients waiting for arthroplasty for osteoarthritis. Increased awareness of this condition will hopefully lead to earlier diagnosis and a successful outcome of conservative treatment. (orig.)

    Primary adrenal insufficiency is a rare condition in pediatric age, and its association with precocious sexual development is very uncommon. We report a 2-yr-old Brazilian boy with DAX1 gene mutation whose first clinical manifestation was isosexual gonadotropin-independent precocious puberty. He presented with pubic hair, enlarged penis and testes, and advanced bone age. T levels were elevated, whereas basal and GnRH-stimulated LH levels were compatible with a prepubertal pattern. Chronic GnRH agonist therapy did not reduce T levels, supporting the diagnosis of gonadotropin-independent precocious puberty. Testotoxicosis was ruled out after normal sequencing of exon 11 of the LH receptor gene. At age 3 yr he developed clinical and hormonal features of severe primary adrenal insufficiency. The entire coding region of the DAX1 gene was analyzed through direct sequencing. A nucleotide G insertion between nucleotides 430 and 431 in exon 1, resulting in a novel frameshift mutation and a premature stop codon at position 71 of DAX-1, was identified. Surprisingly, steroid replacement therapy induced a clear decrease in testicular size and T levels to the prepubertal range. These findings suggest that chronic excessive ACTH levels resulting from adrenal insufficiency may stimulate Leydig cells and lead to gonadotropin-independent precocious puberty in some boys with DAX1 gene mutations.

    The adrenal gland is a common site of disease, with an abnormality prevalence as high as 9% in autopsy series. With the increasing use of CT, adrenal lesions are frequently found in the daily practice of radiology and are diagnosed in up to 5% of CT examinations performed for varied reasons. Imaging features on CT can establish a specific diagnosis of many of these lesions, including myelolipoma, hematoma and cysts. Once a diagnostic dilemma, now adenomas can be accurately diagnosed using unenhanced CT, chemical shift magnetic resonance imaging and CT contrast washout analysis. Because the adrenal gland is also a frequent site of metastasis, recent literature has focused on imaging characterization of adrenal masses for differentiation of adenomas from metastases. In patients without known malignancy, most adrenal lesions are benign and a specific diagnosis can now be made on the basis of imaging features. It is important to understand the prevalence of adrenal abnormalities because the gland is a common site of disorders, and the increased use of cross-sectional imaging has increased the frequency of detection of adrenal lesions. The prevalence of disease is important in predicting the risk of malignancy when an adrenal mass is discovered in a patient without known cancer. Detection of adrenal gland diseases has increased substantially with the advent and widespread use of imaging techniques. Although several imaging modalities can be used, CT has a central role in both detection and differential diagnosis of an adrenal lesion. The aim of this article is to review the CT findings of adrenal gland diseases. (author) [de

    We wanted to evaluate the MDCT findings and concomitant injuries of traumatic adrenal injury in children. Among 375 children who had undergone a MDCT scan for abdominal trauma during the recent five years at our institution, 27 children who had revealed adrenal injury on their CT scan were included in the study. We retrospectively evaluated the causes of the trauma, the patterns of adrenal injury, the associated CT findings and the concomitant injuries of the other organs in the abdomen. We identified 27 children (7.5%) (17 boys and 10 girls, mean age: 9.9 years, range: 2-18 years) with adrenal injury. The causes of adrenal injury were a traffic accident for 20 patients (74%), falls for four patients (15%) and blunt trauma for three patients (11%). The right adrenal gland was injured in 20 patients (74%), while the left adrenal gland was injured in three patients and bilateral involvement was noted in four patients. The patterns of adrenal injury were round or oval shaped hematoma in 23 lesions (74%), irregular hemorrhage with obliterating the gland in six lesions (19%) and active extravasation of contrast material from the adrenal region in two lesions (7%). Concomitant injuries were noted in 22 patients (81%), including 15 patients with liver laceration (56%), 11 patients with lung contusion (41%) and nine patients with renal injury (33%). The frequency of adrenal injury was 7.5%. The right adrenal gland was more frequently involved. Concomitant organ injury was noted 81% of the patients and the most frequently involved organ was the liver (56%)

    Meningioma growth has been previously described in patients receiving oestrogen/progestogen therapy. We describe the clinical, radiological, biochemical and pathologic findings in a 45-year-old woman with congenital adrenal hyperplasia secondary to a defect in the 21-hydroxylase enzyme who had chronic poor adherence to glucocorticoid therapy with consequent virilisation. The patient presented with a frontal headache and marked right-sided proptosis. Laboratory findings demonstrated androgen excess with a testosterone of 18.1 nmol/L (0-1.5 nmol) and 17-Hydroxyprogesterone >180 nmol/L (transsexual patients undergoing therapy with high-dose oestrogen and progestogens. Progesterone receptor positivity has been described previously in meningiomas. 17-Hydroxyprogesterone is elevated in CAH and has affinity and biological activity at the progesterone receptor. Therefore, we hypothesise that patients who have long-standing increased adrenal androgen precursor concentrations may be at risk of meningioma growth. Patients with long-standing CAH (particularly if not optimally controlled) may present with other complications, which may be related to long-standing elevated androgen or decreased glucocorticoid levels.Chronic poor control of CAH is associated with adrenal myelolipoma and adrenal rest tissue tumours.Meningiomas are sensitive to endocrine stimuli including progesterone, oestrogen and androgens as they express the relevant receptors.

    Although radioiodinated cholesterols furnished the first noninvasive imaging of the adrenal glands, it would be desirable to decrease the time for imaging and decrease the radiation dose. The relative tissue distributions of two radiolabeled enzyme inhibitors [ 3 H] metyrapol and 1-125-SKF-12185 were studied in dogs and man. Their percentage uptakes and target-to-nontarget ratios were similar. The adrenals of three dogs were imaged sharply at 2 hr after injection with 4-6 mCi of I-131-SKF-12185, confirmed by subsequent imaging with 1 mCi of I-131-6-beta-19-nor cholesterol at 5 days after injection. The use of 1 mCi of I-123-SKF will pemit imaging of the adrenals in 1-2 hr and will decrease the radiation dose in the human to 0.76 rads to the adrenal, 0.18 rads to the ovaries and 1.7 rads to the liver

  18. Adrenal clocks and the role of adrenal hormones in the regulation of circadian physiology.

    2015-02-01

    The mammalian circadian timing system consists of a master pacemaker in the suprachiasmatic nucleus (SCN) and subordinate clocks that disseminate time information to various central and peripheral tissues. While the function of the SCN in circadian rhythm regulation has been extensively studied, we still have limited understanding of how peripheral tissue clock function contributes to the regulation of physiological processes. The adrenal gland plays a special role in this context as adrenal hormones show strong circadian secretion rhythms affecting downstream physiological processes. At the same time, they have been shown to affect clock gene expression in various other tissues, thus mediating systemic entrainment to external zeitgebers and promoting internal circadian alignment. In this review, we discuss the function of circadian clocks in the adrenal gland, how they are reset by the SCN and may further relay time-of-day information to other tissues. Focusing on glucocorticoids, we conclude by outlining the impact of adrenal rhythm disruption on neuropsychiatric, metabolic, immune, and malignant disorders. © 2014 The Author(s).

    Using Indium-113m and the Gamma Retina V (Fucks-Knipping Camera), the minimal cardiac transit times (MTTs) were measured radiocardiographically from the right auricle to the aortic root. This analysis served to determine the relation between stroke volume and the segment volume of the part of circulation between the right auricle and the aortic root. In 39 patients with myocardial insufficiency of different clinical degree the effectiveness of digitalization was, up to a period of 5 years, measured by means of the volume relation mentioned above. The following conclusions can be drawn from the results: digitalization of patients with myocardial insufficiency leads to an improvement of the impaired relation of central volumes. In patients with diminished cardiac reserve the improvement is drastic and often results in a nearly complete normalization. The data remain constant during therapy even for an observation period of 5 years. Digitalization of patients with congestive heart failure only leads to a partial improvement. In contrast to patients with diminished cardiac reserve this effect is temporary. The different behaviour of the relation between stroke volume and segment volume in patients with diminished cardiac reserve and congestive heart failure under prolonged administration of digitalis points to the necessity of treatment with digitalis in the early stage of myocardial disease.

    Congenital adrenal hyperplasia (CAH) requires parents to inject their child with hydrocortisone intramuscularly during times of illness and adrenal crisis. The purpose of this study was to describe circumstances surrounding adrenal crisis events in children with CAH; to explore parents' perceptions of the consequences of having a child with a life-threatening condition; and to examine a relationship between parents' perceived management ability and the impact CAH has on the family. In Phase 1 of this mixed-methods, cross-sectional study, 77 parents were asked to complete questionnaires comprising measures of family life in the context of childhood illness. Descriptive statistics were computed with four separate analyses using linear mixed models allowing for correlation between responses from parents of the same family and for the variance to be different for fathers and mothers. The following relationships were examined: (1) parental management ability and type of provider instruction on how to manage adrenal crises; (2) parental management ability and child age; (3) the perceived impact of the condition on the family and management ability; and (4) the age of the child and number of adrenal crisis events. In Phase 2, 16 semi-structured interviews were conducted to elicit detailed descriptions of parents' experiences in managing crises. There was a significant, positive relationship between detailed provider instruction to parents on adrenal crisis management and perceived management ability (p = .02), additionally the stronger the perceived management ability, the less impact CAH had on the family (p crisis events and less perceived ability to manage the condition when compared with parents of older children (p = .009). The threat of an adrenal crisis event is a pervasive concern for parents, especially when they are not being properly prepared by providers. Provider support is needed for these parents throughout childhood, but especially in the first 5 years of

On arrival his blood pressure was 229/117mmHg, and he was ill-appearing. His blood pressure was managed aggressively, and he was diagnosed with extra-adrenal pheochromocytoma by computed tomography. He eventually underwent resection of the mass. Children with severe, symptomatic hypertension should be evaluated for pheochromocytoma. Although rare, it is curable. Failure to diagnose carries a high risk of morbidity and mortality. [West J Emerg Med. 2011;12(2:258-261.

    Purpose: To evaluate the incidence and cause of hypertension prospectively during adrenal radiofrequency ablation (RFA). Methods: For this study, approved by our institutional review board, written informed consent was obtained from all patients. Patients who received RFA for adrenal tumors (adrenal ablation) and other abdominal tumors (nonadrenal ablation) were included in this prospective study. Blood pressure was monitored during RFA. Serum adrenal hormone levels including epinephrine, norepinephrine, dopamine, and cortisol levels were measured before and during RFA. The respective incidences of procedural hypertension (systolic blood pressure >200 mmHg) of the two patient groups were compared. Factors correlating with procedural systolic blood pressure were evaluated by regression analysis.ResultsNine patients underwent adrenal RFA and another 9 patients liver (n = 5) and renal (n = 4) RFA. Asymptomatic procedural hypertension that returned to the baseline by injecting calcium blocker was found in 7 (38.9%) of 18 patients. The incidence of procedural hypertension was significantly higher in the adrenal ablation group (66.7%, 6/9) than in the nonadrenal ablation group (11.1%, 1/9, P 2 = 0.68, P 2 = 0.72, P < 0.0001) levels during RFA. The other adrenal hormones did not show correlation with procedural systolic blood pressure. Conclusion: Hypertension occurs frequently during adrenal RFA because of the release of catecholamine.

    The results of quantitative adrenal imaging using 75 Se selenomethylcholesterol in sixty-two subjects are analysed. The adrenal area was localized by a renal scan, lateral views of which enabled adrenal depth to be estimated. The first nineteen cases were scanned with a rectilinear scanner and the remaining forty-three cases imaged with a gamma camera. Quantitation of adrenal uptake was performed on computer-stored static images obtained 7 and 14 days post-injection of 75 Se selenomethylcholesterol (3 and 6 days in the first ten cases studied). Normal uptake was found to be 0.07-0.30% of the administered dose. Overall predictive accuracy of the type of adrenal disorder of thirty-two patients with Cushing's syndrome was 90.6%. Overall predictive accuracy of the cause of Conn's syndrome in twenty-two cases was 86.4%. The mean uptake in the normal adrenal in cases of unilateral adenoma was 0.19% (range 0.07-0.30%). Causes of unsatisfactory adrenal imaging are examined. The procedure is recommended as the localizing and lateralizing technique of choice in Cushing's syndrome except where due to adrenal carcinoma, and as an important non-invasive technique in Conn's syndrome for the lateralization of adenoma.

    Purpose: To evaluate the incidence and cause of hypertension prospectively during adrenal radiofrequency ablation (RFA). Methods: For this study, approved by our institutional review board, written informed consent was obtained from all patients. Patients who received RFA for adrenal tumors (adrenal ablation) and other abdominal tumors (nonadrenal ablation) were included in this prospective study. Blood pressure was monitored during RFA. Serum adrenal hormone levels including epinephrine, norepinephrine, dopamine, and cortisol levels were measured before and during RFA. The respective incidences of procedural hypertension (systolic blood pressure >200 mmHg) of the two patient groups were compared. Factors correlating with procedural systolic blood pressure were evaluated by regression analysis.ResultsNine patients underwent adrenal RFA and another 9 patients liver (n = 5) and renal (n = 4) RFA. Asymptomatic procedural hypertension that returned to the baseline by injecting calcium blocker was found in 7 (38.9%) of 18 patients. The incidence of procedural hypertension was significantly higher in the adrenal ablation group (66.7%, 6/9) than in the nonadrenal ablation group (11.1%, 1/9, P < 0.0498). Procedural systolic blood pressure was significantly correlated with serum epinephrine (R{sup 2} = 0.68, P < 0.0001) and norepinephrine (R{sup 2} = 0.72, P < 0.0001) levels during RFA. The other adrenal hormones did not show correlation with procedural systolic blood pressure. Conclusion: Hypertension occurs frequently during adrenal RFA because of the release of catecholamine.

    Objective: To evaluate the value of dynamic MR imaging in the differential diagnosis of adrenal adenomas and malignant tumors, especially in cases with atypical adenomas. Materials and methods: Sixty-four masses (48 adenomas, 16 malignant tumors) were included in this prospective study. Signal loss of masses was evaluated using chemical shift MR imaging. Five dynamic series of T1-weighted spoiled gradient echo (FFE) images were obtained, with the acquisition starting simultaneously with i.v. contrast administration (0-100 s) followed by a T1-weighted FFE sequence in the late phase (5th minute). Contrast enhancement patterns in the early (25th second) and late (5th minute) phase images were evaluated. For the quantitative evaluation, signal intensity (SI)-time curves were obtained according to the SIs on the 0th, 25th, 50th 75th and 100th second. Also, the wash-in rate, maximum relative enhancement, time-to-peak, and wash-out of contrast at 100 s of masses in both groups were calculated. The statistical significance was determined by Mann-Whitney U test. To evaluate the diagnostic performance of the quantitative tests, receiver operating characteristic (ROC) analysis was performed. Results: Chemical shift MR imaging was able to differentiate 44 out of 48 adenomas (91.7%) from non-adenomas. The 4 adenomas (8.3%) which could not be differentiated from non-adenomas by this technique did not exhibit signal loss on out-of-phase images. With a cut-off value of 30, SI indices of adenomas had a sensitivity of 93.8%, specificity of 100% and a positive predictive value of 100%. On visual evaluation of dynamic MR imaging, early phase contrast enhancement patterns were homogeneous in 75% and punctate in 20,83% of the adenomas; while patchy in 56.25% and peripheral in 25% of the malignant tumors. On the late phase images 58.33% of the adenomas showed peripheral ring-shaped enhancement and 10.41% showed heterogeneous enhancement. All of the malignant masses showed heterogeneous

    Radioisotopic renal function tests are of assistance to diagnose and follow-up the course of renal insufficiency. The radioisotopic renogram is useful in assessing the response to therapy of child obstructive uropathies and evaluating renal transplant function. The renal scan is helpful, in an emergency service, to differenciate chronic renal insufficiency from acute renal insufficiency. Hg renal uptake test provides informations on physiopathological problems. Among them, the following problems are emphasized: evolution of a nonfunctioning kidney, control of the success of a reparative surgery and of bilateral obstructive uropathies with unilateral symptoms [fr

    This study aimed to investigate the suppressive effect of nicotine on fetal adrenal steroidogenesis and to explore the potential role of epigenetic modification of steroidogenic factor-1 (SF-1) transcriptional activity in this process. Nicotine was intragastrically administered to pregnant rats and NCI-H295A cells were treated with nicotine or trichostatin A (TSA). The pathomorphology of fetal adrenals, steroid hormone levels, the expression of SF-1 and its target genes, and histone deacetylase (HDAC) mRNA were analyzed. Histone modification and DNA methylation of the SF-1 promoter region were assessed using chromatin immunoprecipitation (ChIP) and bisulfite sequencing PCR. The interaction between SF1 and its target genes was observed. Prenatal nicotinic exposure decreased fetal body weight, increased the IUGR rate and caused detrimental changes in fetal adrenal. In addition, the levels of corticosterone, the expression of SF-1 and its target genes were decreased while HDAC2 expression was enhanced. Nicotine treatment decreased histone H3K9 and H3K14 acetylation levels while there was no effect on the methylation frequency on the SF-1 promoter region. Furthermore, in nicotine-treated NCI-H295A cells, lower levels of steroidogenic synthesis, lower expression of SF-1 and its target genes were observed while the expression of HDACs was enhanced. The interaction between SF1 and StAR decreased with nicotine treatment. Nicotine treatment decreased histone H3K9 and H3K14 acetylation levels, and addition of TSA reversed the inhibition of nicotine-mediated SF-1 and its partial target genes. Thus, nicotine-mediated reduction of SF-1 expression resulted in an inhibitory effect on the expression of its target genes and steroid production via histone deacetylation. - Highlights: • Prenatal nicotine-exposed suppresses fetal adrenal steroidogenesis. • Nicotine-supressed fetal adrenal steroidogenesis is related to SF-1 deacetylation. • Prenatal nicotinic exposure decreased

    Full Text Available Adrenal vein development in utero occurs concurrently with the development of the inferior vena cava, the renal veins, and the gonadal veins. The embryologic formation of these veins involves communication of various venous systems. Although the left adrenal-renal vein complex is most commonly described as a shared emptying of the left adrenal vein and the left inferior phrenic vein into the left renal vein, there have been reports of numerous anatomic variations of this complex. In this report, we present a case of a rare variant of the left adrenal vein, in which the left adrenal vein empties into the left gonadal vein, which takes an atypical course superolateral to the left kidney.

    Numerous studies have shown that the hypothalamic-pituitary-adrenal (HPA) axis is hyperactive in some depressed patients. It is unclear whether such hyperactivity results in changed volumes of the adrenal glands, pituitary gland and hypothalamus. We systematically reviewed all controlled studies...... on the adrenal or pituitary glands or hypothalamus volume in unipolar depressive disorder published in PubMed 1966 to December 2009. We identified three studies that investigated the volume of the adrenal glands and eight studies that examined the volume of the pituitary gland, but no studies on hypothalamus...... were found. Two out of three studies found a statistically significant increase in adrenal volume in patients compared to controls. Four out of eight studies found a statistically significant increase in pituitary volume in patients compared to controls. Different methodological problems were...

    Full Text Available Adrenal myelolipoma is an unusual, benign and biochemically inactive tumor that is composed of mature adipose and hematopoietic tissue. It is usually diagnosed accidentally and nowadays much more frequently because of widespread use of ultrasonography, computed tomography (CT and magnetic resonance imaging. Adrenal myelolipoma is usually unilateral and asymptomatic, though known to be associated with obesity, hypertension, endocrinological disorders and some malignancies. We report herein two cases of right-sided giant adrenal myelolipoma diagnosed by multidetector-row CT. One patient was symptomatic because of a large mass in the right upper abdomen, which on imaging with CT was seen to be right adrenal myelolipoma. Another patient had a large left side Bochdalek hernia and right adrenal myelolipoma was incidentally discovered on CT.

    Adrenal glands are common sites of diseases. With dramatically increased use of computed tomography (CT) and magnetic resonance (MR) imaging, more and more uncommon adrenal masses have been detected incidentally at abdominal examinations performed for other purposes. In this article, uncommon adrenal masses are classified as cystic masses (endothelial cysts, epithelial cysts, parasitic cysts, and pseudocysts), solid masses (ganglioneuroma, ganglioneuroblastoma, extramedullary plasmacytoma (EMP), neurilemmoma, and lymphoma), fat-containing masses (myelolipoma, teratoma), and infectious masses (tuberculoma), and the imaging features of these uncommon masses are demonstrated. Although most of these lesions do not have specific imaging features, some fat-containing masses and cystic lesions present with characteristic appearances, such as myelolipoma, teratoma, and hydatid. Combination with histopathologic characteristic of these uncommon masses of adrenal gland, radiological features of these lesions on CT and MR imaging can be accurately understood with more confidences. Moreover, CT and MRI are highly accurate in localization of uncommon adrenal masses, and useful to guide surgical treatments

Adrenal vein sampling (AVS is a procedure entailing the measurement of aldosterone from both adrenal veins, to diagnose an adrenal source of excess aldosterone secretion. Because unilateral adrenal etiologies of primary aldosteronism may be surgically resected, identifying these sources by venous sampling is critical. Technical aspects of the procedure are reviewed, with emphasis on strategies to avoid common difficulties during AVS. Keywords: primary aldosteronism, hypertension, venous sampling, adrenal adenoma

    Full Text Available Advanced cancer occurs with nutritional and metabolic alterations that characterize neoplastic cachexia. When homeostasis is compromised, the adrenal glands have a fundamental role in the neuroendocrine response. Our purpose in this research was to study morphological alterations of the adrenal glands in the development of cancer associated to cachexia. Cachexia experimental model induced by Walker 256 tumor in Wistar rats, was used. Animals were sacrificed 12 days after tumor cells inoculation and adrenal glands removal for histopathologic analysis by means of hematoxylin and eosin stain. Nutritional parameters, cachexia index and adrenal glands weight, were evaluated. Animals with tumor presented cachexia index of 16,6 ± 4%. Adrenal glands average weight was significantly higher in the tumor group (40 mg ± 10 than in the control group (25 mg ± 3. Adrenal cortex of animals with cachexia showed hypertrophy of the zona fasciculata and reticular layer, with voluminous spongiocytes; vascular congestion and stasis were observed in the medullar region. Results were similar in the pair and ad libitum-fed groups. Animals with cancer cachexia showed compromised morphology of the adrenal glands which showed alterations related to stress response, suggesting increased cathecolamine secretion and activation of the hypothalamus-pituitary-adrenal axis.   Advanced cancer occurs with nutritional and metabolic alterations that characterize neoplastic cachexia.

    Considerable evidence indicates that adrenal hormones may affect gonadal function. To assess the role of some adrenal hormones in human follicular fluid and their relationship with the ability of the oocyte to be fertilized and then to cleave in vitro, cortisol and dehydroepiandrosterone sulfate were measured in follicular fluid obtained at the time of oocyte recovery for in vitro fertilization from cycles stimulated by clomiphene citrate, human menopausal gonadotropin and human chorionic gonadotropin. Thirty-six follicular fluid containing mature oocyte-corona-cumulus complexes and free of visible blood contamination were included in this study. There was no significant difference in follicular fluid dehydroepiandrosterone sulfate concentration between follicles with oocytes which did or did not fertilize (5.1 +/- 1.1 vs 5.8 +/- 2.0 mumol/l). However, follicular fluid from follicles whose oocytes were not fertilized had levels of cortisol significantly higher than those in follicular fluid from follicles containing successfully fertilized oocytes (406.0 +/- 75.9 vs 339.2 +/- 37.0 nmol/l; p < 0.005). No significant correlations were found between rates of embryo cleavage and cortisol and dehydroepiandrosterone levels in follicular fluid. We conclude that cortisol levels in follicular fluid may provide an index of fertilization outcome, at least in stimulated cycles by clomiphene citrate, human menopausal gonadotropin and human chorionic gonadotropin.

  1. Laparoscopic and robotic adrenal surgery: transperitoneal approach.

    Okoh, Alexis K; Berber, Eren

    2015-10-01

    Recent advances in technology and the need to decrease surgical morbidity have led a rapid progress in laparoscopic adrenalectomy (LA) over the past decade. Robotics is attractive to the surgeon owing to the 3-dimensional image quality, articulating instruments, and stable surgical platform. The safety and efficacy of robotic adrenalectomy (RA) have been demonstrated by several reports. In addition, RA has been shown to provide similar outcomes compared to LA. Development of adrenal surgery has involved the description of several surgical approaches including the anterior transperitoneal, lateral transperitoneal (LT) and posterior retroperitoneal (PR). Among these, the most frequently preferred technique is LT adrenalectomy, primarily due to the surgeon's familiarity of the operative field, wider working space and visibility. The LT technique is suitable for the resection of larger, unilateral tumors and in scenarios where conversion to an open transperitoneal approach is warranted, it offers a lesser burden. Also, the larger view of the entire abdominal cavity and excellent exposure of both adrenal glands and surrounding structures provided by the LT technique render it safe and feasible in pediatric and pregnant individuals.

    Cortical-sparing adrenalectomy is a suitable treatment for hereditary and sporadic bilateral pheochromocytoma, in cases of low risk of malignancy, to reduce the possibility of adrenal insufficiency assuming the chance of local recurrence. The aim of the study is to analyze the functional results of partial adrenalectomy by retroperitoneal endoscopic approach in single-adrenal patients or patients requiring bilateral adrenalectomy. Prospective study between January 2015 and February 2016 including pheochromocytoma patients diagnosed with low risk of malignant mutations. All patients agreed to be included in the study. Experienced endocrine surgeons who have been trained in minimally invasive endocrine surgery performed the procedure using the same surgical technique. Demographic variables and clinical characteristics were collected, subsequently carrying out the descriptive analysis of the data. A total of 6 patients were registered, four associated with MEN type 2 syndrome and two in the context of VHL syndrome. Retroperitoneoscopic resection was performed without laparoscopic or open conversion and no postoperative complications; the average hospital stay was 2.5 days. Preservation of the functional cortex without corticosteroids was achieved in 5 (83%) of out 6 cases with a follow-up of 26.2 ± 6 months. Today, these 5 patients have a preserved adrenal function without hormone replacement. Cortical-sparing adrenalectomy by the retroperitoneal endoscopic approach, in expert hands, is safe and feasible for the treatment of hereditary and sporadic pheochromocytoma in a context of low malignancy, making it possible to avoid the need for corticoid replacement in most cases.

    Hemorrhagic hypotension produces an increase in adrenal medullary blood flow and a decrease in adrenal cortical blood flow. To determine whether changes in adrenal blood flow during hemorrhage are neurally mediated, the authors compared blood flow responses following adrenal denervation (splanchnic nerve section) with changes in the contralateral, neurally intact adrenal. Carbonized microspheres labeled with 153 Gd, 114 In, 113 Sn, 103 Ru, 95 Nb or 46 Se were used. Blood pressure was reduced and maintained at 60 mmHg for 25 min by hemorrhage into a pressurized bottle system. Adrenal cortical blood flow decreased to 50% of control with hemorrhage in both the intact and denervated adrenal. Adrenal medullary blood flow increased to four times control levels at 15 and 25 min posthemorrhage in the intact adrenal, but was reduced to 50% of control at 3, 5, and 10 min posthemorrhage in the denervated adrenal. In a separate group of dogs, the greater splanchnic nerve on one side was electrically stimulated at 2, 5, or 15 Hz for 40 min. Adrenal medullary blood flow increased 5- to 10-fold in the stimulated adrenal but was unchanged in the contralateral, nonstimulated adrenal. Adrenal cortical blood flow was not affected by nerve stimulation. They conclude that activity of the splanchnic nerve profoundly affects adrenal medullary vessels but not adrenal cortical vessels and mediates the observed increase in adrenal medullary blood flow during hemorrhagic hypotension

    Full Text Available Abstract: Cancer patients experience weight loss for a variety of reasons, commencing with the tumor’s metabolism (Warburg effect and proceeding via cachexia to loss of appetite. In pancreatic cancer, several other factors are involved, including a loss of appetite with a particular aversion to meat and the incapacity of the pancreatic gland to function normally when a tumor is present in the pancreatic head. Pancreatic exocrine insufficiency is characterized by a deficiency of the enzymes secreted from the pancreas due to the obstructive tumor, resulting in maldigestion. This, in turn, contributes to malnutrition, specifically a lack of fat-soluble vitamins, antioxidants, and other micronutrients. Patients with pancreatic cancer and pancreatic exocrine insufficiency have, overall, an extremely poor prognosis with regard to surgical outcome and overall survival. Therefore, it is crucial to be aware of the mechanisms involved in the disease, to be able to diagnose pancreatic exocrine insufficiency early on, and to treat malnutrition appropriately, for example, with pancreatic enzymes.

The patient was administrated with additional chemotherapy but he passed away 7 months later due to infection in the lungs. Intravascular lymphoma should be suspected in patients with bilateral adrenal masses who present with rapidly progressive adrenal insufficiency.Publicamos el caso poco frecuente de un varón de 68 años de edad que debutó con insuficiencia adrenal y fue diagnosticado de linfoma de alto grado de células B grandes ubicado principalmente en las glándulas suprarrenales. Al paciente le administraron quimioterapia adicional, pero falleció 7 meses después de infección pulmonar. El linfoma intravascular debe sospecharse en los pacientes con masas suprarrenales bilaterales que presenten insuficiencia adrenal rápidamente progresiva.

    1. Adrenalectomy or adrenal demedullation affected neither the levels of endogenous catecholamines in the rat heart nor the accumulation of 3H-noradrenaline 1 hr after its intravenous administration. 2. Twenty-four hours after intravenous administration of labelled amine, however, its retention was markedly reduced in the heart of adrenalectomized or demedullated rats. Ganglionic blockade prevented this reduction. 3. Rate calculations from the decline of catecholamine levels after blockade of synthesis with α-methyl-tyrosine showed that cardiac synthesis of noradrenaline increased about four-fold after demedullation and about three-fold after adrenalectomy. This increase in synthesis may compensate for the loss of circulating catecholamines. 4. There was no change in catechol-o-methyl-transferase activity, but monoamine oxidase activity was increased in the homogenates of the heart of adrenalectomized and demedullated rats. The increase in the cardiac monoamine oxidase activity was markedly greater in the adrenalectomized rats than in the demedullated rats. 5. It is suggested that adrenal cortex insufficiency may modulate the rate of synthesis of noradrenaline and monoamine oxidase activity in cardiac sympathetic neurones. PMID:5360339

    Full Text Available Adrenal incidentalomas (AIs are usually discovered incidentally after imaging unrelated to adrenal glands. We aimed to evaluate standard risk factors for systemic atherosclerosis and echocardiographic changes in patients with nonfunctioning AIs and compare them with normal subjects. We evaluated 70 patients diagnosed with AIs and 51 healthy controls. Mean levels were determined for HbA1c, LDL, uric acid, fasting plasma insulin, HOMA, and neutrophil-to-lymphocyte ratio (NLR, and these values were found to be significantly higher in the patients than the controls. The mean left atrial diameter, interventricular septum thickness, posterior wall thickness, left ventricular mass, E-wave deceleration time, isovolumetric relaxation time, and the median ratio of the early transmittal flow velocity to the early diastolic tissue velocity (E/Em were higher in patients with AIs compared to controls. The mitral annular early diastolic velocity was lower in patients with AIs. The mean aortic diastolic diameter, stiffness index (SI, and aortic strain were higher, and aortic distensibility was lower in the patients. The mean right ventricular diameter, right atrial major-axis diameter, and right atrial minor-axis diameter were statistically higher in the patient group than the controls. A negative correlation was found between the NLR and aortic strain and aortic distensibility, while a positive correction was found between the NLR and SI. We found altered left ventricular (LV and right ventricular (RV echocardiographic findings in patients with AIs without known cardiovascular disease. Aortic stiffness was also increased. These changes may be related to an increase in cardiovascular risk factors in AI patients.

    We have evaluated characteristics of adrenal masses incidentally observed in nonenhanced F-18 FDG PET/CT of the oncologic patients and the diagnostic ability of F-18 FDG PET/CT to differentiate malignant from benign adrenal masses. Between Mar 2005 and Aug 2008, 75 oncologic patients (46 men, 29 women; mean age, 60.8±10.2 years; range, 35-87 years) with 89 adrenal masses incidentally found in PET/CT were enrolled in this study. For quantitative analysis, size (cm), Hounsfield unit (HU), maximum standardized uptake value (SUVmax), SUVratio of all 89 adrenal masses were measured. SUVmax of the adrenal mass divided by SUVliver, which is SUVmax of the segment 8, was defined as SUVratio. The final diagnosis of adrenal masses was based on pathologic confirmation, radiologic evaluation (HU<0 : benign), and clinical decision. Size, HU, SUVmax, and SUVratio were all significantly different between benign and malignant adrenal masses.(P < 0.05) And, SUVratio was the most accurate parameter. A cut-off value of 1.0 for SUVratio provided 90.9% sensitivity and 75.6% specificity. In small adrenal masses (1.5 cm or less), only SUVratio had statistically significant difference between benign and malignant adrenal masses. Similarly a cut-off value of 1.0 for SUVratio provided 80.0% sensitivity and 86.4% specificity. F-18 FDG PET/CT can offer more accurate information with quantitative analysis in differentiating malignant from benign adrenal masses incidentally observed in oncologic patients, compared to nonenhanced CT

    Objectives: To evaluate the safety and long-term efficacy of computed tomography-guided percutaneous ethanol ablation for benign primary and secondary hyper functioning adrenal disorders. Method: We retrospectively evaluated the long-term results of nine patients treated with computed tomography guided percutaneous ethanol ablation: eight subjects who presented with primary adrenal disorders, such as pheochromocytoma, primary macro nodular adrenal hyperplasia and aldosterone-producing adenoma, and one subject with Cushing disease refractory to conventional treatment. Eleven sessions were performed for the nine patients. The patient data were reviewed for the clinical outcome and procedure-related complications over ten years. Results: Patients with aldosterone-producing adenoma had clinical improvement: symptoms recurred in one case 96 months after ethanol ablation, and the other patient was still in remission 110 months later. All patients with pheochromocytoma had clinical improvement but were eventually submitted to surgery for complete remission. No significant clinical improvement was seen in patients with hypercortisolism due to primary macro nodular adrenal hyperplasia or Cushing disease. Major complications were seen in five of the eleven procedures and included cardiovascular instability and myocardial infarction. Minor complications attributed to sedation were seen in two patients. Conclusion: Computed tomography-guided ethanol ablation does not appear to be suitable for the long-term treatment of hyper functioning adrenal disorders and is not without risks. (author)

  14. Adrenal gland infection by serotype 5 adenovirus requires coagulation factors.

    Full Text Available Recombinant, replication-deficient serotype 5 adenovirus infects the liver upon in vivo, systemic injection in rodents. This infection requires the binding of factor X to the capsid of this adenovirus. Another organ, the adrenal gland is also infected upon systemic administration of Ad, however, whether this infection is dependent on the cocksackie adenovirus receptor (CAR or depends on the binding of factor X to the viral capsid remained to be determined. In the present work, we have used a pharmacological agent (warfarin as well as recombinant adenoviruses lacking the binding site of Factor X to elucidate this mechanism in mice. We demonstrate that, as observed in the liver, adenovirus infection of the adrenal glands in vivo requires Factor X. Considering that the level of transduction of the adrenal glands is well-below that of the liver and that capsid-modified adenoviruses are unlikely to selectively infect the adrenal glands, we have used single-photon emission computed tomography (SPECT imaging of gene expression to determine whether local virus administration (direct injection in the kidney could increase gene transfer to the adrenal glands. We demonstrate that direct injection of the virus in the kidney increases gene transfer in the adrenal gland but liver transduction remains important. These observations strongly suggest that serotype 5 adenovirus uses a similar mechanism to infect liver and adrenal gland and that selective transgene expression in the latter is more likely to be achieved through transcriptional targeting.

    To assess the contribution of adrenal-derived androgens in women with hirsutism, adrenal scintigrams under dexamethasone suppression (DS) were performed on 35 women with increasing facial or body hair and irregular or absent menses. Based upon the DS regimen chosen (8 mg/d for 2 days or 4 md/d for 7 days before the injection of 6..beta..-(/sup 131/I)iodomethylnorcholesterol), three imaging patterns were identified. The first was the absence of uptake before 3 days (8-mg DS) or before 5 days (4-mg DS) after injection. This imaging pattern was seen in 17 of the 35 patients studied and was considered normal. The second pattern was bilateral uptake earlier than 3 days (8-mg DS regimen) or 5 days (4-mg DS) after injection. This was seen in 13 of the 35 patients and was interpreted as bilateral early visualization. Adrenal-vein catheterization performed on six patients with this pattern showed increased adrenal-vein testosterone. The third pattern, observed in five patients, was unilateral early visualization, which in four cases investigated to date was the result of an adrenocortical adenoma. This study confirms the adrenal cortex as a source of androgens in women with hirsutism and hyperandrogenism and demonstrates that DS adrenal scintigraphy can be utilized to identify those women in whom adrenal-derived androgens contribute to their hyperandrogenism.

    To assess whether dietary supplements that are herbal and/or animal-derived products, marketed for enhancing metabolism or promoting energy, "adrenal fatigue," or "adrenal support," contain thyroid or steroid hormones. Twelve dietary adrenal support supplements were purchased. Pregnenolone, androstenedione, 17-hydroxyprogesterone, cortisol, cortisone, dehydroepiandrosterone sulfate, synthetic glucocorticoids (betamethasone, dexamethasone, fludrocortisone, megestrol acetate, methylprednisolone, prednisolone, prednisone, budesonide, and triamcinolone acetonide) levels were measured twice in samples in a blinded fashion. This study was conducted between February 1, 2016, and November 1, 2016. Among steroids, pregnenolone was the most common hormone in the samples. Budesonide, 17-hydroxyprogesterone, androstenedione, cortisol, and cortisone were the others in order of prevalence. All the supplements revealed a detectable amount of triiodothyronine (T3) (63-394.9 ng/tablet), 42% contained pregnenolone (66.12-205.2 ng/tablet), 25% contained budesonide (119.5-610 ng/tablet), 17% contained androstenedione (1.27-7.25 ng/tablet), 8% contained 17-OH progesterone (30.09 ng/tablet), 8% contained cortisone (79.66 ng/tablet), and 8% contained cortisol (138.5 ng/tablet). Per label recommended doses daily exposure was up to 1322 ng for T3, 1231.2 ng for pregnenolone, 1276.4 ng for budesonide, 29 ng for androstenedione, 60.18 ng for 17-OH progesterone, 277 ng for cortisol, and 159.32 ng for cortisone. All the supplements studied contained a small amount of thyroid hormone and most contained at least 1 steroid hormone. This is the first study that measured thyroid and steroid hormones in over-the-counter dietary "adrenal support" supplements in the United States. These results may highlight potential risks of hidden ingredients in unregulated supplements. Copyright © 2017 Mayo Foundation for Medical Education and Research. Published by Elsevier Inc.

    We describe a new technique for extensive retropositioning of the soft palate for the treatment of velopharyngeal insufficiency. This technique is identified as a nasopharyngeal pushback, and has been used repeatedly in conjunction with both a Cronin nasal flap and a superiorly based pharyngeal flap when maximum retropositioning was needed. This procedure has been used for over ten years, each time obtaining an additional pushback distance equal to or greater than the distance achieved by freeling the soft palate from the posterior border of the hard palate.

    Periadrenal and adrenal portosystemic collaterals are a recently reported cause of adrenal pseudotumor on computed tomography (CT). Nine patients with this left adrenal pseudotumor illustrate its typical position and appearance on CT, angiography, CT-angiography, and magnetic resonance imaging (MRI). The anatomic basis for variceal adrenal pseudotumors is the left inferior phrenic vein, which passes immediately anterior to the left adrenal gland and which serves as a collateral pathway from splenic to left renal vein in portal hypertension. Thus, unlike previously described adrenal pseudotumors, these venous collaterals are not anatomically distinguishable from the adrenal gland on CT. Bolus dynamic CT is usually diagnostic, but in equivocal cases, MRI may prove useful

    Full Text Available Congenital adrenal hyperplasia (CAH describes a group of autosomal recessive disorders where there is impairment of cortisol biosynthesis. CAH due to 21-hydroxylase deficiency accounts for 95% of cases and shows a wide range of clinical severity. Glucocorticoid and mineralocorticoid replacement therapies are the mainstays of treatment of CAH. The optimal treatment for adults with CAH continues to be a challenge. Important long-term health issues for adults with CAH affect both men and women. These issues may either be due to the disease or to steroid treatment and may affect final height, fertility, cardiometabolic risk, bone metabolism, neuro-cognitive development and the quality-of-life. Patients with CAH should be regularly followed-up from childhood to adulthood by multidisciplinary teams who have knowledge of CAH. Optimal replacement therapy, close clinical and laboratory monitoring, early life-style interventions, early and regular fertility assessment and continuous psychological management are needed to improve outcome.
