    ORIGINAL ARTICLE FARES AND SANTOS Conduct protocol in emergency: Acute adrenal insufficiency ADIL BACHIR FARES1*, RÔMULO AUGUSTO DOS SANTOS2 1Medical Student, 6th year, Faculdade de Medicina de São José do Rio Preto (Famerp), São José do Rio Preto, SP, Brazil 2Degree in Endocrinology and Metabology from Sociedade Brasileira de Endocrinologia e Metabologia (SBEM). Assistant Physician at the Internal Medicine Service of Hospital de Base. Researcher at Centro Integrado de Pesquisa (CIP), Hospital de Base, São José do Rio Preto. Endocrinology Coordinator of the Specialties Outpatient Clinic (AME), São José do Rio Preto, SP, Brazil SUMMARY Introduction: Acute adrenal insufficiency or addisonian crisis is a rare comor- bidity in emergency; however, if not properly diagnosed and treated, it may progress unfavorably. Objective: To alert all health professionals about the diagnosis and correct treatment of this complication. Method: We performed an extensive search of the medical literature using spe- cific search tools, retrieving 20 articles on the topic. Results: Addisonian crisis is a difficult diagnosis due to the unspecificity of its signs and symptoms. Nevertheless, it can be suspected in patients who enter the emergency room with complaints of abdominal pain, hypotension unresponsive to volume or vasopressor agents, clouding, and torpor. This situation may be associated with symptoms suggestive of chronic adrenal insufficiency such as hyperpigmentation, salt craving, and association with autoimmune diseases such as vitiligo and Hashimoto’s thyroiditis.

  • Preventable Deaths: Panhypopituitarism and Adrenal Insufficiency
    Preventable Deaths: Panhypopituitarism and adrenal insufficiency. What you need to know What is panhypopituitarism? Your child has been diagnosed with a big scary sounding word, and all you can think is: 'What does this mean? and 'Why have I never heard of this?' Simply put, panhypopituitarism means that your child's pituitary gland does not function properly and as a result, your child is deficient in one or several hormones. Some children have congenital panhypopituitarism, meaning they are born with it. Others have acquired panhypopituitarism following an event such as head trauma, brain tumor surgery, or brain radiation. It is rare enough that is entirely possible, in fact, probable, that you will not initially know anyone else with this disorder. What will my child need? Although the diagnosis and condition can seem intimidating, it is very manageable once you understand what is needed. Unfortunately the condition cannot be cured or reversed, but again, it can be effectively managed. Your child will need to take medications to replace the missing hormones. These might include thyroid hormone, growth hormone, cortisol, and/or possibly others. Your doctor will go over these with you, as dosages vary from child to child. Most medications are taken orally, but growth hormone must be taken by daily injection. Your endocrinologist will work with you and your child to achieve the proper dosages and will guide you in how to administer any necessary medications. Why is it sometimes life threatening? What is adrenal insufficiency? Of the hormone deficiencies your child may have, the most critical is cortisol, also known as the 'stress hormone.' Cortisol is essential for life , and is therefore the central focus of this guide.

    A Case of Waterhouse-Friderichsen Syndrome in a Patient with Streptococcus Pyogenes Bacteremia D. I. BACAL, B. E. CATALDO, P. M. LUCERI, G. VARALLO Rowan University School of Osteopathic Medicine, and Jefferson University Hospital System, NJ INTRODUCTION Waterhouse-Friderichsen Syndrome (WFS) is a rare condition of adrenal insufficiency (AI) due to adrenal hemorrhage after a severe infection. The incidence of WFS has been estimated at 0.14-1.8% based on post-mortem studies.1 It has been associated with a 55-60% mortality rate.2 Meningococcal disease comprises up to 80% of WFS, but additional causative agents continue to be identified.3 This is the case of a 52-year-old female with toxic shock syndrome from Group A Streptococcal (GAS) bacteremia who developed bilateral adrenal hemorrhage & subsequent AI. Septic shock occurred during an initial hospitalization & resolved. Four weeks after discharge she presented with evidence of an adrenal crisis. CT scans demonstrated bilateral adrenal enlargement concerning for adrenal hemorrhage. Primary AI was confirmed via ACTH stimulation testing. A literature search found fewer than ten cases of WFS described due to streptococcal bacteremia. BACKGROUND OF WATERHOUSE-FRIDERICHSEN SYNDROME CONCLUSIONS • Bilateral adrenal hemorrhage has multiple causes: coagulopathies, sepsis from infection, hypotension (i.e. MI), severe volume loss, or surgical WFS is a rare, often fatal, clinical condition that can develop after a intervention 4 severe infection & leads to adrenal hemorrhage. Many factors • Signs include pallor, weakness, fatigue, anorexia, nausea, vomiting, and lethargy 5,6 & labs often depict hyponatremia & hyperkalemia contribute to the pathogenicity of WFS, including coagulopathy, • Increased skin pigmentation develops due to an increase in proopiomelanocortin (POMC), Bacterial ischemia & bacterial toxins.

The aim of management is usually to replace the target-hormone of hypothalamo-pituitary-endocrine gland axis with the exceptions of secondary hypogonadism when fertility is required, and growth hormone deficiency (GHD), and to safely minimise both symptoms and clinical signs. Adrenocorticotropic hormone deficiency replacement is best performed with the immediate-release oral glucocorticoid hydrocortisone (HC) in 2–3 divided doses. However, novel once-daily modified-release HC targets a more physiological exposure of glucocorticoids. GHD is treated currently with daily subcutaneous GH, but current research is focusing on the development of once-weekly administration of recombinant GH. Hypogonadism is targeted with testosterone replacement in men and on estrogen replacement therapy in women; when fertility is wanted, replacement targets secondary or tertiary levels of hormonal settings. Thyroid-stimulating hormone replacement therapy follows the rules of primary thyroid gland failure with L-thyroxine replacement.

CAH is a genetic disorder of the adrenal glands that affects the body's general health, growth, and development. What are the adrenal glands? The adrenal glands are a pair of walnut-sized organs above the kidneys. They make hormones, which act like chemical messengers to affect other organs in the body. Each adrenal gland has two parts: the medulla (the inner part), and the cortex (the outer part).The medulla makes the hormone adrenaline. The cortex makes the hormones cortisol, aldosterone, and androgens. CAH affects how the adrenal cortex works. In severe cases, the adrenal medulla may also not function normally. What do adrenal hormones do? Hormones made by the adrenal glands are important for the body's normal function.

  • Adrenal Insufficiency?
    What do I need to know about Adrenal Insufficiency? PATIENT INFORMATION LEAFLET This information leaflet provides an introduction to the causes and symptoms of adrenal insufficiency and the tests used to diagnose this condition. Produced by the Society for Endocrinology ENDORSED BY: ADRENAL GLANDS What are the adrenal glands? The adrenal glands sit at the top of the kidneys, one on each side of the body, and have an inner core (known as the medulla) surrounded by an outer shell (known as the cortex). The inner medulla produces adrenaline, the “fight or flight” stress hormone. While the absence of the adrenal medulla does not cause disease, the cortex is more critical. It produces the steroid KIDNEYS hormones that are essential for life: cortisol and aldosterone. Cortisol mobilises nutrients, enables the body to fight inflammation, stimulates the liver to produce blood sugar and also helps control the amount of water in the body. Aldosterone regulates salt and water levels which affect blood volume and blood pressure. The adrenal cortex also produces sex hormones known as adrenal androgens; the most important of these is a hormone called DHEA (dehydroepiandrosterone). What is adrenal insufficiency? Adrenal insufficiency is caused by failure of the adrenal glands to produce sufficient (or any) amounts of cortisol and aldosterone. Prolonged lack of cortisol leads to severe fatigue, chronic exhaustion, depression, loss of appetite and weight loss. Lack of aldosterone leads to a drop in blood pressure, particularly when standing up quickly, and to disturbed salt levels in the blood. Sometimes patients also describe a craving for salty food.
