This presentation highlights different causes of central adrenal insufficiency, its evaluation and treatment. The presentation focuses on adrenal insufficiency due to withdrawal of exogenous glucocorticoid with a case story.
This document summarizes adrenal insufficiency, including its history, causes, presentation, investigations, treatment, and management of adrenal crisis. It discusses how adrenal insufficiency can be primary or secondary, caused by conditions like autoimmunity, infections, genetic disorders, or exogenous steroid use. Signs include fatigue, weight loss, low blood pressure, and pigmentation. Diagnosis involves tests like the cosyntropin stimulation test. Treatment is hormone replacement of glucocorticoids and mineralocorticoids. Adrenal crisis requires immediate intravenous hydrocortisone and fluid resuscitation.
This document discusses the anatomy, physiology, and pathological disorders of the adrenal glands and their management during anaesthesia. It describes the adrenal cortex and medulla, hormone production and regulation. Pathologies covered include Cushing's syndrome, Conn's syndrome, hypoaldosteronism, and primary/secondary adrenal insufficiency. Perioperative management focuses on fluid/electrolyte balance, stress dosing of steroids, and monitoring for adrenal crises. Determining return of normal adrenal function and intensive care management are also outlined.
The document discusses primary adrenal insufficiency. It describes the structure and function of the adrenal glands, including the adrenal cortex which secretes glucocorticoids and mineralocorticoids, and the adrenal medulla which secretes catecholamines. It then discusses the causes, signs and symptoms, diagnosis, and treatment of primary adrenal insufficiency. The main causes are autoimmune adrenalitis, infectious adrenalitis, hemorrhage, metastases, and drugs. Signs include fatigue, weakness, weight loss, and electrolyte abnormalities. Diagnosis involves ACTH stimulation and cortisol tests. Treatment consists of lifelong glucocorticoid and mineralocorticoid replacement therapy.
A 19-year-old man presented with red urine, periorbital and pretibial edema. He was diagnosed with tonsillitis 3 weeks prior. Examination found hypertension and crackles in both lung bases. Urine analysis showed proteinuria and dysmorphic red blood cells. The most likely diagnosis is poststreptococcal glomerulonephritis resulting from the recent streptococcal infection. Treatment involves controlling hypertension, edema and complications through diuretics and sodium restriction. Renal biopsy showed diffuse proliferative glomerulonephritis with neutrophils and immune deposits consistent with poststreptococcal glomerulonephritis.
This document summarizes adrenal gland function and adrenal insufficiency. It describes:
1) The adrenal glands produce cortisol, aldosterone, and androgens which regulate stress response, electrolyte balance, and sex characteristics.
2) Primary adrenal insufficiency results from adrenal gland dysfunction and causes deficiencies in cortisol, aldosterone, and sex hormones. Secondary adrenal insufficiency is caused by pituitary or hypothalamic disease and causes cortisol deficiency alone.
3) Adrenal crisis is a life-threatening emergency characterized by refractory hypotension that requires aggressive treatment with glucocorticoid replacement such as hydrocortisone.

- A 55-year-old male presented with 3 weeks of weakness, fatigue, and weight loss. Physical exam found him to be thin and lean with oral pigmentation.
- Labs found leukopenia, a positive PPD test, low cortisol, increased ACTH, and a normal chest x-ray.
- The final diagnosis was tuberculosis adrenalitis, which had caused primary adrenal insufficiency.
Mr. NKH, a 45-year-old man with untreated hypertension for 10 years, presented with a blood pressure of 200/110 mmHg and grade III hypertensive retinopathy. He was diagnosed with hypertensive urgency and started on antihypertensive medications, with the goal of reducing his blood pressure by 25% over 24 hours. After 6 months of treatment, his blood pressure remained elevated at 150/90 mmHg despite adherence to treatment with 3 antihypertensives including a diuretic. He was diagnosed with resistant hypertension, likely contributed to by his high salt diet. Adding a fourth drug such as spironolactone was recommended to better control his blood pressure.
Adrenal insufficiency can occur when the adrenal glands or pituitary gland fail to produce adequate hormones. Symptoms include weakness, fatigue, loss of appetite, and low blood pressure. Laboratory findings may include hyponatremia and hyperkalemia. Treatment involves lifelong hormone replacement therapy with glucocorticoids and mineralocorticoids. Unexplained hypotension resistant to fluids and pressors should raise suspicion for adrenal crisis, which requires stress-dose glucocorticoid treatment in the ICU.

The document discusses several adrenal gland disorders including:
1. Addison's disease, which is caused by inadequate production of hormones by the adrenal glands due to problems with the pituitary gland or autoimmune destruction of the adrenal glands.
2. Cushing's syndrome, which is caused by excessive cortisol production from either benign or cancerous tumors of the adrenal glands or pituitary gland.
3. Pheochromocytoma, a rare tumor of the adrenal medulla that secretes excess catecholamines and causes symptoms like headaches and sweating.
4. Testing of the corticotropin-releasing factor is discussed as a way to diagnose hypothal
This document discusses adrenal insufficiency, including its anatomy, physiology, causes, clinical features, diagnosis, treatment and follow up. It notes that adrenal insufficiency can be primary, secondary or tertiary. Primary is failure of the adrenal glands, most commonly due to autoimmune disease like Addison's. Secondary is failure of the HPA axis, usually due to exogenous steroids. Tertiary is hypothalamic dysfunction. Adrenal crisis can occur in untreated patients and requires ICU care with IV steroids. Treatment involves glucocorticoid and mineralocorticoid replacement depending on the type of insufficiency.
This document discusses hypoadrenalism, including primary and secondary adrenal insufficiency. It notes that the adrenal cortex produces glucocorticoids, mineralocorticoids, and androgen precursors. Primary adrenal insufficiency can be caused by autoimmune adrenalitis, congenital adrenal hyperplasia, infections, tumors, or drugs. Secondary adrenal insufficiency results from hypothalamic-pituitary dysfunction. Symptoms include fatigue, low blood pressure, and electrolyte abnormalities. Treatment involves glucocorticoid and mineralocorticoid replacement therapy.

This document discusses adrenal insufficiency, including its clinical presentation, treatment options, and a case study. The clinical presentation of chronic adrenal insufficiency includes fatigue, weight loss, low blood pressure, hyperpigmentation, and hormonal changes. Acute adrenal insufficiency or adrenal crisis can be life-threatening and causes resistant hypotension. Treatment involves glucocorticoid and mineralocorticoid replacement therapies with medications like hydrocortisone, dexamethasone, and fludrocortisone. A case study found that postoperative steroid replacement after adrenalectomy is only required for patients with Cushing's syndrome or bilateral adrenalectomy.
- The patient is a 60-year-old male who presented to the clinic with severe chest pain for 3 hours. Tests showed ST elevation on ECG and positive troponin levels, indicating ST elevation myocardial infarction (STEMI).
- The patient has a history of hypertension and hyperlipidemia. Echo showed no blood flow to part of the myocardium.
- The initial treatment plan included aspirin, clopidogrel, metoprolol, atorvastatin, lisinopril, ranitidine, morphine, and glyceryl trinitrate as needed for pain. Long-term medication and lifestyle changes were also recommended.
Eclampsia is a complication of preeclampsia defined by the occurrence of seizures. It is caused by severe vasospasm and damage to the vascular endothelium in the brain. Convulsions typically occur in late pregnancy or early postpartum. Management involves controlling seizures with magnesium sulfate, controlling blood pressure, and delivering the baby to ultimately cure the condition. Complications can be serious for both mother and baby if not properly managed.

5-hydroxytryptamine or 5-HT or Serotonin is a neurotransmitter that serves a range of roles in the human body. It is sometimes referred to as the happy chemical since it promotes overall well-being and happiness.
It is mostly found in the brain, intestines, and blood platelets.
5-HT is utilised to transport messages between nerve cells, is known to be involved in smooth muscle contraction, and adds to overall well-being and pleasure, among other benefits. 5-HT regulates the body's sleep-wake cycles and internal clock by acting as a precursor to melatonin.
It is hypothesised to regulate hunger, emotions, motor, cognitive, and autonomic processes.
This presentation gives information on the pharmacology of Prostaglandins, Thromboxanes and Leukotrienes i.e. Eicosanoids. Eicosanoids are signaling molecules derived from polyunsaturated fatty acids like arachidonic acid. They are involved in complex control over inflammation, immunity, and the central nervous system. Eicosanoids are synthesized through the enzymatic oxidation of fatty acids by cyclooxygenase and lipoxygenase enzymes. They have short half-lives and act locally through autocrine and paracrine signaling.

GASTROINTESTINAL INFECTIONS AND GASTRITIS
Osvaldo Bernardo Muchanga
Gastrointestinal Infections
GASTROINTESTINAL INFECTIONS result from the ingestion of pathogens that cause infections at the level of this tract, generally being transmitted by food, water and hands contaminated by microorganisms such as E. coli, Salmonella, Shigella, Vibrio cholerae, Campylobacter, Staphylococcus, Rotavirus among others that are generally contained in feces, thus configuring a FECAL-ORAL type of transmission.
Among the factors that lead to the occurrence of gastrointestinal infections are the hygienic and sanitary deficiencies that characterize our markets and other places where raw or cooked food is sold, poor environmental sanitation in communities, deficiencies in water treatment (or in the process of its plumbing), risky hygienic-sanitary habits (not washing hands after major and/or minor needs), among others.
These are generally consequences (signs and symptoms) resulting from gastrointestinal infections: diarrhea, vomiting, fever and malaise, among others.
The treatment consists of replacing lost liquids and electrolytes (drinking drinking water and other recommended liquids, including consumption of juicy fruits such as papayas, apples, pears, among others that contain water in their composition).
To prevent this, it is necessary to promote health education, improve the hygienic-sanitary conditions of markets and communities in general as a way of promoting, preserving and prolonging PUBLIC HEALTH.
Gastritis and Gastric Health
Gastric Health is one of the most relevant concerns in human health, with gastrointestinal infections being among the main illnesses that affect humans.
Among gastric problems, we have GASTRITIS AND GASTRIC ULCERS as the main public health problems. Gastritis and gastric ulcers normally result from inflammation and corrosion of the walls of the stomach (gastric mucosa) and are generally associated (caused) by the bacterium Helicobacter pylor, which, according to the literature, this bacterium settles on these walls (of the stomach) and starts to release urease that ends up altering the normal pH of the stomach (acid), which leads to inflammation and corrosion of the mucous membranes and consequent gastritis or ulcers, respectively.
In addition to bacterial infections, gastritis and gastric ulcers are associated with several factors, with emphasis on prolonged fasting, chemical substances including drugs, alcohol, foods with strong seasonings including chilli, which ends up causing inflammation of the stomach walls and/or corrosion. of the same, resulting in the appearance of wounds and consequent gastritis or ulcers, respectively.
Among patients with gastritis and/or ulcers, one of the dilemmas is associated with the foods to consume in order to minimize the sensation of pain and discomfort.

PGx Analysis in VarSeq: A User’s PerspectiveGolden Helix
Since our release of the PGx capabilities in VarSeq, we’ve had a few months to gather some insights from various use cases. Some users approach PGx workflows by means of array genotyping or what seems to be a growing trend of adding the star allele calling to the existing NGS pipeline for whole genome data. Luckily, both approaches are supported with the VarSeq software platform. The genotyping method being used will also dictate what the scope of the tertiary analysis will be. For example, are your PGx reports a standalone pipeline or would your lab’s goal be to handle a dual-purpose workflow and report on PGx + Diagnostic findings.
The purpose of this webcast is to:
Discuss and demonstrate the approaches with array and NGS genotyping methods for star allele calling to prep for downstream analysis.
Following genotyping, explore alternative tertiary workflow concepts in VarSeq to handle PGx reporting.
Moreover, we will include insights users will need to consider when validating their PGx workflow for all possible star alleles and options you have for automating your PGx analysis for large number of samples. Please join us for a session dedicated to the application of star allele genotyping and subsequent PGx workflows in our VarSeq software.

20.
21. Case contd.
● Initially diagnosed as RA flare with left pneumonia with UTI with right protrusio
acetabuli with Cushingoid feature
● Treatment started with IV antibiotics (amikacin and piperacillin/tazobactam),
IV fluids, prednisolone 5 mg
22. Case contd.
Possibility of long term exogenous glucocorticoid use in our patient
● Cushingoid appearance
● Possible use of steroid in the form of alternative medicine for long duration
● Developed DM (may be steroid induced)
● Developed AVN right hip (possibly due to long term steroid)
● Started to develop joints pain after stopping the alternative medicine use
causing flare of RA (possibly due to steroid withdrawal)
● Developed chest infection, that could have precipitated adrenal insufficiency
23. Exogenous glucocorticoid
● Most common cause of adrenal insufficiency
● Withdrawal of high dose glucocorticoid
● Decreases hypothalamic CRH synthesis and secretion (tertiary)
● Also blocks CRH action in pituitary (secondary)
● Decreased synthesis of POMC, hence ACTH
● Atrophy of pituitary corticotrophs
● Atrophy of zona fasciculata and reticularis in adrenal
25. HPA Axis Suppression with prolonged glucocorticoid
● HPA suppression likely
● Intermediate/uncertain risk of HPA suppression
● HPA suppression unlikely
● > 20 mg/day of prednisolone
equivalent for > 3 weeks
● Evening/bedtime dose of ≥5 mg of
prednisone for more than a few
weeks
● Cushingoid appearance
26. HPA Axis Suppression with prolonged glucocorticoid
● HPA suppression likely
● Intermediate/uncertain risk of HPA suppression
● HPA suppression unlikely
● 10- 20 mg/day of prednisolone for >
3 weeks
● < 10 mg/day of prednisolone for
more than a few weeks (provided
that it is not taken as a single
bedtime dose)
27. HPA Axis Suppression with prolonged glucocorticoid
● HPA suppression likely
● Intermediate/uncertain risk of HPA suppression
● HPA suppression unlikely
● Any dose of glucocorticoid for < 3
weeks
● Alternate-day prednisolone at a
dose < 10 mg
28. Evaluation of HPA Axis Suppression
● HPA suppression likely
● Intermediate/uncertain risk of HPA suppression
● HPA suppression unlikely
29. Evaluation of HPA Axis Suppression
● HPA suppression likely
● Intermediate/uncertain risk of HPA suppression
● HPA suppression unlikely
● Do not need morning cortisol
testing to diagnose HPA
suppression
● Consider adrenal insufficiency if
presence of unexplained nausea,
vomiting, hypotension, orthostasis,
change in mental status,
hyponatremia, or hyperkalemia
● Check a random cortisol, and give
empiric additional corticosteroid
30. Evaluation of HPA Axis Suppression
● HPA suppression likely
● Intermediate/uncertain risk of HPA suppression
● HPA suppression unlikely ● Check serum morning cortisol (8
AM)
○ < 138 nmol/l- highly
suggestive of impaired HPA
axis, need additional steroid
○ 138- 275 nmol/l- ACTH
stimulation test or empiric
additional steroid
○ > 275 nmol/l- HPA
suppression unlikely, no need
of additional steroid
31. Evaluation of HPA Axis Suppression
● HPA suppression likely
● Intermediate/uncertain risk of HPA suppression
● HPA suppression unlikely
● No need of evaluating for HPA axis
suppression
● Can continue with usual steroid
regimen
32. Evaluation of HPA Axis Suppression
● Low dose ACTH (1 mcg) stimulation test is typically used
● Cortisol level before and 30 min after the injection
● The criteria for serum cortisol is a minimum value ≥18 mcg/dL (500 nmol/L)
33. Case contd.
● Morning cortisol (8 AM)- 67.5 nmol/L
Normal range (123-626 nmol/L)
● Diagnosis of central adrenal insufficiency was made
● Inj Hydrocortisone 50 mg QID started
● Later changed to prednisolone and tapered slowly
34. Cortisol response during stress
● Acute physical or psychological stress activates the HPA axis, resulting in
increased ACTH and serum cortisol concentrations
● Normal basal secretion of cortisol from the adrenal gland is 8-10 mg/day
● Minor surgery or illness- 50 mg/day
● Greater surgical stress (eg, subtotal colectomy)- 75 to 100 mg/day
● Severe stress (such as major trauma)- 200 to 500 mg/day
35. Cortisol response during stress
Patients with HPA axis suppression
● Unable to increase cortisol level while on stress such as acute illness or
surgery
● Land up on adrenal crisis (adrenal insufficiency)
● Hence require additional glucocorticoid
36. Treatment during stress
● Little information about how much additional glucocorticoid is needed
● Minor illnesses (eg URTI)- 3 by 3 rule
Increasing the usual glucocorticoid use to 3 times for 3 days
37. Treatment during stress
● Minor surgery- hydrocortisone 25 mg for the day of operation only, with a
return to the usual replacement dose on the second day
● Moderate surgical stress (cholecystectomy, joint replacement)-
hydrocortisone 50- 75 mg on the day of surgery and the 1st POD, with a
return to the usual dose on the 2nd POD
● Major surgery (cardiac bypass)- 100- 150 mg hydrocortisone for 2- 3 days,
then returning to the usual dose
38. Treatment during stress
Emergency precautions
● Medical alert bracelet including the diagnosis and dose of usual steroid
● Should carry injectable glucocorticoids (100 mg hydrocortisone/ 4 mg
dexamethasone)
● Family members should be instructed to inject the glucocorticoids in following
scenarios
○ Injury with substantial blood loss or fracture
○ Nausea and vomiting and inability to retain oral medications
○ Symptoms of acute adrenal insufficiency
○ Patient is found unresponsive
39. Maintenance steroid to those with HPA suppression
● Hydrocortisone 15 to 25 mg orally in 2-3 divided doses (largest dose in
morning upon awakening; typically 10 mg upon arising in morning, 5 mg early
afternoon, 2.5 mg late afternoon)
● Prednisone 5 mg (range: 2.5 to 7.5 mg) orally at bedtime
● Dexamethasone 0.75 mg (range: 0.25 to 0.75 mg) orally at bedtime
● Monitor clinical symptoms and morning plasma ACTH
40. Glucocorticoid tapering regimen
To prevent acute adrenal crisis in patients taking long term glucocorticoid with
likely HPA suppression
Prednisolone dose Tapering by
> 40 mg/day 5- 10 mg/day every 1-2 weeks
20-40 mg/day 5 mg/day every 1-2 weeks
10-20 mg/day 2.5 mg/day every 2-3 weeks
5-10 mg/day 1 mg/day every 2-4 weeks
</= 5 mg/day 0.5 mg/day every 2-4 weeks
41. Glucocorticoid tapering
● Patients with rheumatic diseases may complain of recurrent symptoms of the
underlying disease, during the tapering of steroid
● May be difficult to distinguish between mild symptoms of glucocorticoid
withdrawal (ie, arthralgia and myalgia or "pseudorheumatism") or
recrudescence of the underlying rheumatic disease
● If mild symptoms, NSAIDs for 7-10 days, if symptoms resolve-
pseudorheumatism
● If symptoms do not subside, then possible flare, increase the prednisone
dose by 10-15 % followed by taper
42. Adrenal crisis
● Common with primary adrenal insufficiency
● Uncommon in central insufficiency- due to presence of aldosterone
● May occur in
○ HPA axis suppressed patients during acute stress
○ Abrupt withdrawal of glucocorticoid in those using long term
45. Adrenal crisis
Precipitants
● Infections, gastroenteritis
● Injuries and surgery
● Procedures such as vaccination, zoledronate infusion
● Immunotherapy/ chemotherapy
● Non adherence to glucocorticoid replacement therapy
● Undiagnosed coexisting thyrotoxicosis, or the initiation of thyroxine therapy in
a patient with undiagnosed hypoadrenalism
● Use of CYP3A4 inducers, withdrawing the use of CYP3A4 inhibitors
46. Adrenal crisis
Management
● Serum electrolytes and glucose and routine measurement of plasma cortisol
and ACTH. Do not wait for lab results
● Infuse 2- 3 liters of NS or 5 % DNS as quickly as possible. Frequent
hemodynamic monitoring and measurement of serum electrolytes to avoid
iatrogenic fluid overload
● 4 mg dexamethasone as IV bolus over 1-5 minutes and every 12 hours
thereafter. Dexamethasone does not interfere with the measurement of
plasma cortisol
● IV hydrocortisone 100 mg immediately and every 6 hours thereafter if
dexamethasone is unavailable
47. Sheehan Syndrome
● Postpartum hypopituitarism
● Rare but potentially life threatening complication of PPH
● Pituitary gland is enlarged during pregnancy
● Hence prone to infarction during hypovolemic shock due to PPH
● Pituitary damage can be mild to severe
● Secretion of one or all hormones affected
48. Sheehan Syndrome
● Commonest presentation-
○ Failure to lactate post-delivery and amenorrhea or oligomenorrhea
● Can present with hypotension, hyponatremia or hypothyroidism
● Occur any time from the immediate postpartum period to years after delivery
49. Sheehan Syndrome
● If the patient remains hypotensive after control of hemorrhage and volume
replacement, she should be evaluated and treated for adrenal insufficiency
immediately
● Evaluation of other hormonal deficiencies can be deferred until four to six
weeks postpartum
