Autoimmune Disorders Associated With Surgical Remission of Cushing's Disease : A Cohort Study.

BACKGROUND: Glucocorticoids suppress inflammation. Autoimmune disease may occur after remission of Cushing's disease (CD). However, the development of autoimmune disease in this context is not well described. OBJECTIVE: To determine 1) the incidence of autoimmune disease in patients with CD after surgical remission compared with patients with nonfunctioning pituitary adenomas (NFPAs) and 2) the clinical presentation of and risk factors for development of autoimmune disease in CD after remission. DESIGN: Retrospective matched cohort analysis. SETTING: Academic medical center/pituitary center. PATIENTS: Patients with CD with surgical remission and surgically treated NFPA. MEASUREMENTS: Cumulative incidence of new-onset autoimmune disease at 3 years after surgery. Assessment for hypercortisolemia included late-night salivary cortisol levels, 24-hour urine free cortisol (UFC) ratio (UFC value divided by the upper limit of the normal range for the assay), and dexamethasone suppression tests. RESULTS: Cumulative incidence of new-onset autoimmune disease at 3 years after surgery was higher in patients with CD (10.4% [95% CI, 5.7% to 15.1%]) than in those with NFPAs (1.6% [CI, 0% to 4.6%]) (hazard ratio, 7.80 [CI, 2.88 to 21.10]). Patients with CD showed higher prevalence of postoperative adrenal insufficiency (93.8% vs. 16.5%) and lower postoperative nadir serum cortisol levels (63.8 vs. 282.3 nmol/L) than patients with NFPAs. Compared with patients with CD without autoimmune disease, those who developed autoimmune disease had a lower preoperative 24-hour UFC ratio (2.7 vs. 6.3) and a higher prevalence of family history of autoimmune disease (41.2% vs. 20.9%). LIMITATION: The small sample of patients with autoimmune disease limited identification of independent risk factors. CONCLUSION: Patients achieving surgical remission of CD have higher incidence of autoimmune disease than age- and sex-matched patients with NFPAs. Family history of autoimmune disease is a potential risk factor. Adrenal insufficiency may be a trigger. PRIMARY FUNDING SOURCE: Recordati Rare Diseases Inc.

Postpartum acute adrenal insufficiency of early-onset Sheehan syndrome: A case series study in a single center.

AIM: To identify the symptoms and relevant factors associated with acute adrenal insufficiency of early-onset Sheehan syndrome. METHODS: We retrospectively reviewed the charts of 125 women admitted to our intensive care unit because of postpartum hemorrhage between January 2011 and December 2021. Three women developed acute adrenal insufficiency. We investigated the total blood loss, shock status, consciousness level upon arrival, and intensive care provided to the women. We also analyzed the symptoms and laboratory data that led to the diagnosis of acute adrenal insufficiency. Continuous variables were presented by median (minimum-maximum). RESULTS: The medians and ranges of age, total blood loss, and shock index [heart rate/systolic blood pressure] on admission were 33.1 (17.2-45.3) years, 3351 (595-20 260) g, and 0.94 (0.55-2.94), respectively. Seven women were older than 40 years, 28 experienced >5000 g blood loss, 17 had shock index >1.5, 27 had impaired consciousness upon arrival, and 15 underwent hysterectomy. Women who developed acute adrenal insufficiency were <40 years old and had a bleeding volume of over 5000 g, impaired consciousness upon arrival, and had undergone hysterectomy. They had experienced lactation failure, presented with hyponatremia-related symptoms on postpartum days 8-9, experienced general malaise, headache, and impaired consciousness, and showed severe hyponatremia. CONCLUSIONS: Massive postpartum hemorrhage over 5000 g, impaired consciousness upon arrival, and hysterectomy as a hemostatic measure were relevant factors associated with acute adrenal insufficiency of early-onset Sheehan syndrome. Hyponatremia-related symptoms occurring after lactation failure are indicative of the onset of acute adrenal insufficiency.

Anterior hypopituitarism due to primary empty sella syndrome in a critically unwell patient.

A previously fit and well male in his early 40s, presented to the emergency department, hypotensive, bradycardic and hypothermic with reduced levels of consciousness after being found diaphoretic and unwell at his home. Despite fluid resuscitation with warmed saline, he remained hypotensive and required vasopressor support leading to intensive care admission. Initially, the patient was managed for suspected meningoencephalitis but was later found to have hypopituitarism leading to secondary hypothyroidism and adrenal insufficiency. Subsequent investigations revealed it is due to empty sella syndrome.

Hypoglycaemia in adrenal insufficiency.

Adrenal insufficiency encompasses a group of congenital and acquired disorders that lead to inadequate steroid production by the adrenal glands, mainly glucocorticoids, mineralocorticoids and androgens. These may be associated with other hormone deficiencies. Adrenal insufficiency may be primary, affecting the adrenal gland's ability to produce cortisol directly; secondary, affecting the pituitary gland's ability to produce adrenocorticotrophic hormone (ACTH); or tertiary, affecting corticotrophin-releasing hormone (CRH) production at the level of the hypothalamus. Congenital causes of adrenal insufficiency include the subtypes of Congenital Adrenal Hyperplasia, Adrenal Hypoplasia, genetic causes of Isolated ACTH deficiency or Combined Pituitary Hormone Deficiencies, usually caused by mutations in essential transcription factors. The most commonly inherited primary cause of adrenal insufficiency is Congenital Adrenal Hyperplasia due to 21-hydroxylase deficiency; with the classical form affecting 1 in 10,000 to 15,000 cases per year. Acquired causes of adrenal insufficiency can be subtyped into autoimmune (Addison's Disease), traumatic (including haemorrhage or infarction), infective (e.g. Tuberculosis), infiltrative (e.g. neuroblastoma) and iatrogenic. Iatrogenic acquired causes include the use of prolonged exogenous steroids and post-surgical causes, such as the excision of a hypothalamic-pituitary tumour or adrenalectomy. Clinical features of adrenal insufficiency vary with age and with aetiology. They are often non-specific and may sometimes become apparent only in times of illness. Features range from those related to hypoglycaemia such as drowsiness, collapse, jitteriness, hypothermia and seizures. Features may also include signs of hypotension such as significant electrolyte imbalances and shock. Recognition of hypoglycaemia as a symptom of adrenal insufficiency is important to prevent treatable causes of sudden deaths. Cortisol has a key role in glucose homeostasis, particularly in the counter-regulatory mechanisms to prevent hypoglycaemia in times of biological stress. Affected neonates particularly appear susceptible to the compromise of these counter-regulatory mechanisms but it is recognised that affected older children and adults remain at risk of hypoglycaemia. In this review, we summarise the pathogenesis of hypoglycaemia in the context of adrenal insufficiency. We further explore the clinical features of hypoglycaemia based on different age groups and the burden of the disease, focusing on hypoglycaemic-related events in the various aetiologies of adrenal insufficiency. Finally, we sum up strategies from published literature for improved recognition and early prevention of hypoglycaemia in adrenal insufficiency, such as the use of continuous glucose monitoring or modifying glucocorticoid replacement.

The 1 µg Synacthen stimulation test in the diagnosis of secondary adrenal insufficiency in patients with Rathke's cleft cyst and empty sella syndrome.

INTRODUCTION: Rathke's cleft cyst (RCC) and primary empty sella syndrome (PESS) are usually incidental findings on magnetic resonance imaging (MRI) scans. In most cases, these lesions do not cause mass effect symptoms and do not require surgical intervention. In patients with RCC or PESS, it is important to exclude secondary adrenal insufficiency (SAI), which may be a life-threatening condition. MATERIAL AND METHODS: The incidence of SAI was assessed in patients with RCC or PESS detected by MRI, using the 1 µg Synacthen stimulation test. A total of 38 patients were analysed. Test results were linked to clinical symptoms and the type of cystic lesion. RESULTS: Assuming that cortisol levels < 14.6 µg/dL in Synacthen test are the criterion of SAI diagnosis, SAI was diagnosed only in 2 patients (5%). Adopting the traditional criterion of cortisol levels < 18 µg/dL, SAI would be diagnosed in 7 patients (18.4 %). Dizziness (Chi2 = 3.89; p = 0.049) and apathy (Chi2 = 3.87; p = 0.049) were significantly more frequent in the PESS group than in the RCC group. CONCLUSIONS: The incidence of SAI in the general patient population with empty sella syndrome and Rathke's cleft cysts is low. The 1 µg Synacthen test seems to be a valuable tool in the diagnosis of SAI among patients with RCC and PESS. Further studies are necessary to determine the sensitivity and specificity of the 1 µg Synacthen test with the standardization of test protocol and considering the cortisol level at the 20-minute timepoint. PESS patients report dizziness and apathy more frequently than RCC patients, which does not result from the disturbance of the hypothalamic-pituitary-adrenal axis, but probably from the different pathogenesis of these cystic lesions.

Bilateral adrenal hemorrhage: learning notes from clinical practice and literature review.

Adrenal hemorrhage is a rare, but important, diagnosis to recognize, in particular when there is involvement of both adrenal glands. Bilateral adrenal hemorrhage can in fact lead to adrenal insufficiency, with dramatic consequences if not promptly recognized and treated. It is normally caused by systemic conditions that lead to the vasoconstriction and thrombosis of the adrenal vein. Oftentimes, the clinical diagnosis of this condition can be very challenging, as its signs and symptoms are generalized and nonspecific (abdominal pain, nausea, and fatigue). Here, we present the cases of two patients admitted to the Emergency Department in 2016 and 2022 with acute abdominal pain, having recently undergone surgery and subsequently prescribed low-molecular-weight heparin. In both cases, laboratory results revealed neutrophilic leukocytosis and an unexplained anemia. Due to the persistence of abdominal pain despite medication, a CT scan was performed, showing an enlargement of both adrenal glands suggestive of bilateral adrenal hemorrhage. Adrenal function was tested that correlated with a diagnosis of adrenal insufficiency, and both patients were promptly treated with parenteral hydrocortisone as a result. On 5 years' follow-up from the acute event, the second patient's adrenal function had returned to normal, and he has not needed further adrenal replacement therapy; the first patient however demonstrated persistence of adrenal failure requiring replacement therapy. In this paper, through our experience and a literature analysis, we will aim to outline some clues to identify patients at potential risk of bilateral adrenal hemorrhage.

Case report: a premature infant with severe intrauterine growth restriction, adrenal insufficiency, and inflammatory diarrhea: a genetically confirmed case of MIRAGE syndrome.

Introduction: MIRAGE syndrome is a rare disease characterized by myelodysplasia, infection, growth restriction, adrenal hypoplasia, genital phenotypes, and enteropathy. Herein, we report the case of a girl with MIRAGE syndrome who presented with adrenal insufficiency and chronic diarrhea. Case presentation: The patient was born at 29 + 6 weeks of gestational age with a birth weight of 656 g (<3p). Her height and head circumference were also <3p. At birth, she presented with respiratory distress, meconium staining, and pneumomediastinum, which were managed with high-frequency ventilation and empirical antibiotics. Physical examination showed generalized hyperpigmentation and normal female genitalia. A few days after birth, polyuria and hypotension developed, and laboratory findings revealed hypoglycemia, hyponatremia, and hyperkalemia. Plasma adrenocorticotropic hormone levels were elevated with low serum cortisol levels and high plasma renin activity, which were suggestive of adrenal insufficiency. Hydrocortisone and fludrocortisone were introduced and maintained, and hyperpigmentation attenuated with time. Both kidneys looked dysplastic, and adrenal glands could not be traced on abdominal ultrasound. From the early days of life, thrombocytopenia and anemia were detected, but not to life-threatening level and slowly recovered up to the normal range. Despite aggressive nutritional support, weight gain and growth spurt were severely retarded during the hospital stay. Additionally, after introducing enteral feeding, she experienced severe diarrhea and subsequent perineal skin rashes and ulcerations. Fecal calprotectin level was highly elevated; however, a small bowel biopsy resulted in non-specific submucosal congestion. The patient was diagnosed with MIRAGE syndrome with SAMD9 gene mutation. She was discharged with tube feeding and elemental formula feeding continued, but chronic diarrhea persisted. By the time of the last follow-up at 15 months of corrected age, she was fortunately not subjected to severe invasive infection and myelodysplastic syndrome. However, she was dependent on tube feeding and demonstrated a severe developmental delay equivalent to approximately 5-6 months of age. Conclusion: The early diagnosis of adrenal crisis and hormone replacement therapy can save the life of -patients with MIRAGE syndrome; however, chronic intractable diarrhea and growth and developmental delay continue to impede the patient's well-being.

Healthcare cost and survival in patients with non-functioning pituitary adenoma.

OBJECTIVE: Pituitary adenomas and their consequences impact mortality and morbidity. We studied the healthcare costs, survival, and cost-effectiveness of growth hormone (GH) vs no GH replacement in patients with non-functioning pituitary adenoma (NFPA). DESIGN AND METHODS: A cohort study including all NFPA patients followed from 1987 or the date of diagnosis until the time of death or December 31, 2019, in the Västra Götaland region, Sweden. Data to assess resource use, costs, survival, and cost-effectiveness were collected from patient records and regional/national healthcare registries. RESULTS: A total of 426 patients with NFPA (274 men) with a follow-up of 13.6 ± 6.8 years (mean ± SD) were included. The total annual healthcare cost was higher in patients receiving GH (€9287) than those without GH (€6770), mainly driven by a higher pharmaceutical cost. Glucocorticoid replacement therapy (P = .02), diabetes insipidus (P = .04), body mass index (BMI) (P < .01), and hypertension (P < .01) were all individually associated with a higher total annual cost. The survival rate was higher in the GH group (HR [hazard ratio] 0.60; P = .01) and reduced in patients with glucocorticoid replacement (HR 2.02; P < .01) or diabetes insipidus (HR 1.67; P = .04). The cost per gained life-year for GH vs no GH replacement was about €37 000. CONCLUSIONS: This healthcare utilization study identified several factors driving the cost of care in NFPA patients, such as GH replacement, adrenal insufficiency, and diabetes insipidus. Life expectancy was increased in those with GH replacement and reduced in patients with adrenal insufficiency and diabetes insipidus.

Acquired idiopathic isolated ACTH deficiency with associated autoimmune thyroiditis in pediatrics: case report and review of the literature.

OBJECTIVES: Isolated ACTH deficiency (IAD) is defined as an impaired secretion of ACTH from the pituitary gland without any other anterior pituitary hormonal deficits. The idiopathic form of IAD has been described mainly in adults and is thought to be caused by an autoimmune mechanism. CASE PRESENTATION: Herein, we present an 11-year-old _prepubertal previously healthy boy, who suffered a severe hypoglycemic episode short after the initiation of thyroxine for autoimmune thyroiditis and was finally diagnosed with secondary adrenal failure due to idiopathic IAD, after all other etiologies were excluded, thought an extensive diagnostic work-up. CONCLUSIONS: Idiopathic IAD is a rare entity of adrenal insufficiency in pediatrics that should be considered as an etiology of secondary adrenal failure in children, when clinical signs of glucocorticoid deficiency are present and other causes are excluded.

Adrenal insufficiency after curative-intent gastric cancer treatment: a case report.

BACKGROUND: Adrenal insufficiency is a life-threatening condition, and advanced gastric cancer is associated with very poor prognosis. Adrenalectomy and/or metastatic invasion of the adrenal glands can cause primary adrenal insufficiency, which in turn can present with symptoms mimicking advanced cancer. CASE PRESENTATION: Herein we report of a 68-year-old White male with a history of left adrenalectomy in conjunction with distal gastrectomy due to gastric adenocarcinoma. At the 2-year follow-up visit after cancer surgery, the patient presented with fatigue, unintentional weight loss, hyperkalemia, and a computed tomography scan with a right adrenal mass. Primary adrenal insufficiency caused by gastric cancer metastatic invasion of the remaining right adrenal gland was established and glucocorticoid therapy initiated. The patient received first line palliative chemotherapy with systemic disease control and subsequent stereotactic body radiotherapy to the right adrenal gland. More than 17 months after pathology-confirmed gastric cancer relapse, there is no clinical nor radiological evidence of active malignant disease and the patient is doing well on glucocorticoid replacement therapy. CONCLUSIONS: This case does not only illustrate the importance of prompt and correct clinical management of adrenal insufficiency, but also that selected patients with advanced gastric cancer can gain from and achieve long-term survival using a multimodal treatment approach.

Future Directions for Adrenal Insufficiency: Cellular Transplantation and Genetic Therapies.

Primary adrenal insufficiency (PAI) occurs in 1 in 5 to 7000 adults. Leading etiologies are autoimmune adrenalitis in adults and congenital adrenal hyperplasia (CAH) in children. Oral replacement of cortisol is lifesaving, but poor quality of life, repeated adrenal crises, and dosing uncertainty related to lack of a validated biomarker for glucocorticoid sufficiency persists. Adrenocortical cell therapy and gene therapy may obviate many of the shortcomings of adrenal hormone replacement. Physiological cortisol secretion regulated by pituitary adrenocorticotropin could be achieved through allogeneic adrenocortical cell transplantation, production of adrenal-like steroidogenic cells from either stem cells or lineage conversion of differentiated cells, or for CAH, gene therapy to replace or repair a defective gene. The adrenal cortex is a high-turnover organ and thus failure to incorporate progenitor cells within a transplant will ultimately result in graft exhaustion. Identification of adrenocortical progenitor cells is equally important in gene therapy, for which new genetic material must be specifically integrated into the genome of progenitors to ensure a durable effect. Delivery of gene-editing machinery and a donor template, allowing targeted correction of the 21-hydroxylase gene, has the potential to achieve this. This review describes advances in adrenal cell transplants and gene therapy that may allow physiological cortisol production for children and adults with PAI.

Adrenal insufficiency revealing bilateral adrenal hemorrhage related to JAK2 V617F-positive essential thrombocythemia: about two cases.

Bilateral adrenal hemorrhage is a rare cause of adrenal insufficiency which has been rarely associated with myeloproliferative neoplasms. Here, we report two cases of bilateral adrenal hemorrhage revealed by abdominal pain, malaise, and fatigue in two octogenarian males previously diagnosed with JAK2 V617F-positive essential thrombocythemia. Both patients were on long-term direct oral anticoagulant treatment for atrial fibrillation. Evolution was favorable under steroid replacement therapy, associated with cytoreduction, aspirin, and switch of direct oral anticoagulants for vitamin K antagonists.

Approach to the Patient With Adrenal Hemorrhage.

Adrenal hemorrhage is an uncommon, underrecognized condition that can be encountered in several clinical contexts. Diagnosing adrenal hemorrhage is challenging due to its nonspecific clinical features. Therefore, it remains a diagnosis that is made serendipitously on imaging of acutely unwell patients rather than with prospective clinical suspicion. Adrenal hemorrhage can follow abdominal trauma or appear on a background of predisposing conditions such as adrenal tumors, sepsis, or coagulopathy. Adrenal hemorrhage is also increasingly reported in patients with COVID-19 infection and in the context of vaccine-induced immune thrombocytopenia and thrombosis. Unexplained abdominal pain with hemodynamic instability in a patient with a predisposing condition should alert the physician to the possibility of adrenal hemorrhage. Bilateral adrenal hemorrhage can lead to adrenal insufficiency and potentially fatal adrenal crisis without timely recognition and treatment. In this article, we highlight the clinical circumstances that are associated with higher risk of adrenal hemorrhage, encouraging clinicians to prospectively consider the diagnosis, and we share a diagnostic and management strategy.

Endocrinopathy After Treatment for Medulloblastoma: Results From the SJMB03 Trial of Risk-Adapted Radiation Therapy.

PURPOSE: The objective of this study was to estimate the cumulative incidence of endocrinopathy in pediatric patients treated for medulloblastoma with surgery, risk-adapted photon craniospinal irradiation, and dose-intensive chemotherapy. METHODS AND MATERIALS: Children and adolescents (n = 156) treated between 2003 and 2013 were evaluated for evidence of endocrinopathy. Clinical information and mean radiation dose to hypothalamus and thyroid were calculated and used to estimate cumulative incidence of growth hormone deficiency, hypothyroidism, adrenal insufficiency, hypogonadism, and precocious puberty. RESULTS: The 5-year cumulative incidences were estimated for growth hormone deficiency, 68.9% (60.9%, 75.6%); hypothyroidism, 48.4% (95% confidence interval (CI), 40.2%-56.1%); adrenal insufficiency, 13.0% (95% CI, 8.3%-18.9%); hypogonadism, 33.9% (95% CI, 25.2%-42.7%); and precocious puberty, 2.0% (95% CI, 0.6%-5.4%). Growth hormone deficiency was associated with increased hypothalamus dose (hazard ratio [HR], 1.035; 95% CI, 1.010-1.061; P = .0055) in average-risk patients and cerebrospinal fluid shunt (HR, 2.532; 95% CI, 1.325-4.838; P = .0049) in high-risk patients. In average-risk patients, hypothyroidism was associated with younger age (HR, 0.902; 95% CI, 0.842-0.973; P = .0070), hypothalamus dose (HR, 1.039; 95% CI, 1.004-1.075; P = .0273), and thyroid dose (HR, 1.070; 95% CI, 1.008-1.136; P = .0263). In high-risk patients, hypothyroidism was associated with increased hypothalamus dose (HR, 1.068; 95% CI, 0.995-1.147; P = .0671) and thyroid dose (HR, 1.050; 95% CI, 1.000-1.104; P = .0515). Adrenal insufficiency was associated with increased hypothalamus dose (HR, 1.112; 95% CI, 1.058-1.170; P < .0001). Growth hormone deficiency incidence was higher when comparing patients treated with cerebrospinal fluid shunt versus those not having a shunt/extraventricular drain placed during initial surgery (HR, 1.712; 95% CI, 1.109-2.643). CONCLUSIONS: Incidence and time to onset of clinically significant endocrinopathy after photon craniospinal irradiation for pediatric medulloblastoma is influenced by radiation dose to target organs and patient age at time of treatment. Advanced radiation therapy methods and dose-reduction strategies are needed to reduce the incidence of endocrinopathy.

Chinese primary adrenal lymphoma complicated with adrenal crisis: A case report and literature review.

Primary adrenal lymphoma (PAL) is an extremely rare malignancy, and it accounts for approximately 1% of non-Hodgkin's lymphoma (NHL). The growth of adrenal lymphoma is characterized by rapid infiltration in the adrenal gland and further involvement and metastasis in other tissues and organs. This report describes the case of a 67-year-old man with fatigue, poor appetite, and weight loss. Positron emission tomography and computed tomography (PET-CT) scan showed irregular mass-like soft tissue density shadows were noted in the bilateral adrenal glands and immunohistochemical (IHC) studies confirmed the diagnosis of PAL with multiple metastases throughout the body. This report characterizes the clinical manifestations in patients with PAL. When the disease progresses to bilateral adrenal involvement, it may be accompanied by adrenal insufficiency or even adrenal crisis occurred.

Emerging phenotypes linked to variants in SAMD9 and MIRAGE syndrome.

Background: Heterozygous de novo variants in SAMD9 cause MIRAGE syndrome, a complex multisystem disorder involving Myelodysplasia, Infection, Restriction of growth, Adrenal hypoplasia, Genital phenotypes, and Enteropathy. The range of additional clinical associations is expanding and includes disrupted placental development, poor post-natal growth and endocrine features. Increasingly, milder phenotypic features such as hypospadias in small for gestational age (SGA) boys and normal adrenal function are reported. Some children present with isolated myelodysplastic syndrome (MDS/monosomy 7) without MIRAGE features. Objective: We aimed to investigate: 1) the range of reported SAMD9 variants, clinical features, and possible genotype-phenotype correlations; 2) whether SAMD9 disruption affects placental function and leads to pregnancy loss/recurrent miscarriage (RM); 3) and if pathogenic variants are associated with isolated fetal growth restriction (FGR). Methods: Published data were analyzed, particularly reviewing position/type of variant, pregnancy, growth data, and associated endocrine features. Genetic analysis of SAMD9 was performed in products of conception (POC, n=26), RM couples, (couples n=48; individuals n=96), children with FGR (n=44), SGA (n=20), and clinical Silver-Russell Syndrome (SRS, n=8), (total n=194). Results: To date, SAMD9 variants are reported in 116 individuals [MDS/monosomy 7, 64 (55.2%); MIRAGE, 52 (44.8%)]. Children with MIRAGE features are increasingly reported without an adrenal phenotype (11/52, 21.2%). Infants without adrenal dysfunction were heavier at birth (median 1515 g versus 1020 g; P < 0.05) and born later (median 34.5 weeks versus 31.0; P < 0.05) compared to those with adrenal insufficiency. In MIRAGE patients, hypospadias is a common feature. Additional endocrinopathies include hypothyroidism, hypo- and hyper-glycemia, short stature and panhypopituitarism. Despite this increasing range of phenotypes, genetic analysis did not reveal any likely pathogenic variants/enrichment of specific variants in SAMD9 in the pregnancy loss/growth restriction cohorts studied. Conclusion: MIRAGE syndrome is more phenotypically diverse than originally reported and includes growth restriction and multisystem features, but without adrenal insufficiency. Endocrinopathies might be overlooked or develop gradually, and may be underreported. As clinical features including FGR, severe infections, anemia and lung problems can be non-specific and are often seen in neonatal medicine, SAMD9-associated conditions may be underdiagnosed. Reaching a specific diagnosis of MIRAGE syndrome is critical for personalized management.

Susceptibility and characteristics of infections in patients with glucocorticoid excess or insufficiency: the ICARO tool.

Objective: Registry data show that Cushing's syndrome (CS) and adrenal insufficiency (AI) increase mortality rates associated with infectious diseases. Little information is available on susceptibility to milder forms of infections, especially those not requiring hospitalization. This study aimed to investigate infectious diseases in patients with glucocorticoid disorders through the development of a specific tool. Methods: We developed and administered the InfeCtions in pAtients with endocRinOpathies (ICARO) questionnaire, addressing infectious events over a 12-month observation period, to 1017 outpatients referred to 4 University Hospitals. The ICARO questionnaire showed good test-retest reliability. The odds of infection (OR (95% CI)) were estimated after adjustment for confounders and collated into the ICARO score, reflecting the frequency and duration of infections. Results: In total, 780 patients met the inclusion criteria: 43 with CS, 32 with adrenal incidentaloma and mild autonomous cortisol secretion (MACS), and 135 with AI, plus 570 controls. Compared to controls, CS was associated with higher odds of urinary tract infections (UTIs) (5.1 (2.3-9.9)), mycoses (4.4 (2.1-8.8)), and flu (2.9 (1.4-5.8)). Patients with adrenal incidentaloma and MACS also showed an increased risk of UTIs (3.7 (1.7-8.0)) and flu (3.2 (1.5-6.9)). Post-dexamethasone cortisol levels correlated with the ICARO score in patients with CS. AI was associated with higher odds of UTIs (2.5 (1.6-3.9)), mycoses (2.3 (1.4-3.8)), and gastrointestinal infections (2.2 (1.5-3.3)), independently of any glucocorticoid replacement dose. Conclusions: The ICARO tool revealed a high prevalence of self-reported infections in patients with glucocorticoid disorders. ICARO is the first of its kind questionnaire, which could be a valuable tool for monitoring infections in various clinical settings.

Primary adrenal insufficiency masking as an adrenal B-cell lymphoma.

We report here a woman in her 70s presenting with adrenal insufficiency secondary to a primary adrenal lymphoma. The patient had a previous history of aphthous ulcers on dexamethasone and was referred to endocrinology with symptoms of fatigue and orthostasis. Subsequent Cosyntropin stimulation showed primary adrenal insufficiency and adrenal CT demonstrated large infiltrative masses. Adrenal biopsy confirmed the diagnosis of primary adrenal lymphoma of the B-cell type. This case demonstrates the importance of including lymphoma in the differential diagnosis of adrenal insufficiency, particularly in the elderly population and in the setting of negative 21-hydroxlyase antibody results.

Unusual manifestations of adrenal insufficiency: A case report of hypopituitarism and Well's syndrome after apoplexy of a silent pituitary gonadotropic adenoma.

RATIONALE: Pituitary apoplexy occurs in about 8% of those with nonfunctioning pituitary adenoma. Subsequent hormone deficiency, especially corticotropic deficiency, is the most common finding. We describe the unusual manifestations of adrenal insufficiency that are usually overlooked in such cases, with the aim of raising awareness of this disease. PATIENT CONCERNS: A 53-year-old male with a history of hyponatremia came to our hospital with intermittent fever and generalized pruritic skin rash. He also reported general weakness, abdominal pain, poor appetite, and severe retroorbital headache. DIAGNOSES: Laboratory data revealed hypereosinophilia, hypotonic hyponatremia, and hypopituitarism, including secondary adrenal insufficiency. Sellar magnetic resonance imaging revealed a pituitary macroadenoma, 2 cm in height, with mild displacement of the optic chiasm. Pathologic report and immunohistochemical stains of surgical specimen showed pituitary gonadotropic adenoma with apoplexy. INTERVENTIONS: Transsphenoidal removal of the pituitary adenoma was performed. The patient received intravenous hydrocortisone then oral form cortisone acetate regularly. OUTCOMES: His symptoms and laboratory data recovered after the operation and medical treatment. LESSONS: This case highlights that eosinophilia, pruritic skin rash and fever can be manifestations of adrenal insufficiency, and that they may initially be regarded as cellulitis.
