scenario 1 mian seher munir
Scenario 1 (Mian Seher Munir)

An obese 50-year old man presents with high blood glucose levels. He shows buffalo torso and moon face and is complaining of purple striae after injury.

The laboratory blood tests show high blood RBC’s and relative polycythemia, hypokalemia and hyponatremia.

A patient reports to the doctor with edematous appearance of his face apparently moon face with excessive deposition of fats in thoracic and upper abdominal region. His blood pressure is also high. On examination doctor comes to know that the patient has excessive growth of facial hair and acne problems.

Lab reports show that his plasma ACTH & cortisol levels are high. He also has:

  • Low WBC’s
  • Hyperglycemia and hyperkalemia

What would you suspect that patient will be suffering from:

  • Hypoadrenalism
  • Hyperadrenalism
  • Hyperthyroidism
disorders of the adrenal gland

DISORDERS OF THE ADRENAL GLAND

Dr. Ayisha Qureshi

MBBS, MPhil

primary aldosteronism conn s syndrome
DEFINITION:

Conn’s Syndrome is the disorder caused by the hypersecretion of Aldosterone due to primary cause or defect in the zona glomerulosa itself.

Primary aldosteronism(conn’s syndrome)
causes of primary adrenocortical failure
Causes of Primary Adrenocortical failure:

It may occur due to:

  • Addison’s disease
  • Congenital Adrenal Hypoplasia
  • Secondary Adrenocortical failure
  • Pituitary destruction
hypoadrenalism addison s disease
DEFINITION:

It is a disorder caused by the inability of the adrenal cortex to produce the cortical hormones. This is frequently caused by the primary atrophy of the adrenal cortex. The patient presents with mineralocorticoid and glucocorticoid deficiency.

Hypoadrenalism- ADDISON’S DISEASE
cause
CAUSE:

The causes can be:

  • Autoimmune disorder
  • Tuberculous destruction of the glands
  • Cancer
  • Iron overload
signs symptoms
Signs & Symptoms

Mineralocorticoid deficiency

Glucocorticoid deficiency

Patient cannot maintain normal blood glucose levels as no gluconeogenesis b/w meals. Patient cannot Fast.

Nausea, vomiting, fever, diorrheoaand anemia.

All metabolisms effected leading to fatigue and sluggishness.

Patient highly susceptible to the deteriorating effects of stress.

Even mild infections can lead to death.

Pigmentation of the skin in the form of blotches b/c of increased secretion of ACTH as feedback. These brownish-black areas appear in axilla, genital areas, lips, buccal mucosa.

  • Greatly decreased renal sodium reabsorption.
  • Increased loss of Na, Cl & water in the urine.
  • Decreased ECF leading to hypovolemia leading to dehydration.
  • Hyponatremia leading to cramps.
  • Hyperkalemia.
  • Mild Acidosis.
  • Hypotension.
  • Decreased Cardiac output.
  • Shock.
  • Death within 4 days to 2 weeks after complete cessation of the aldosterone production.
treatment
TREATMENT
  • A person with complete destruction of the adrenal may die within a few days b/c of weakness & circulatory shock.
  • However, if small quantities of mineralo & glucocorticoids are administered daily, they can live for years.
addisonian crisis
ADDISONIAN CRISIS
  • In a person with Addison\'s disease, the output of glucocorticoids does not increase during stress. Yet whenever different types of trauma, disease, or other stresses, such as surgical operations, supervene, a person is likely to have an acute need for excessive amounts of glucocorticoids and often must be given 10 or more times the normal quantities of glucocorticoids to prevent death.
  • This critical need for extra glucocorticoids and the associated severe disease state in times of stress is called an addisonian crisis.
hyperadrenalism cushing s syndrome
DEFINITION:

Hypersecretion by the adrenal cortex causes a complex cascade of hormone effects called Cushing\'s syndrome. Many of the abnormalities are due to abnormal amounts of cortisol but increased amounts of aldosterone and androgens are also responsible.

Hyperadrenalism- Cushing’s Syndrome
causes
CAUSES:
  • Exogenous
  • ACTH-Dependant

- Pituitary adenoma

- Ectopic ACTH syndrome

  • ACTH-Independant

- Adrenal adenoma

- Adrenal carcinoma

slide25

When Cushing’s syndrome is secondary to excess secretion of ACTH by the anterior pituitary, it is called CUSHING’S DISEASE.

signs symptoms1
Signs & Symptoms
  • Truncal Obesity
  • Supraclavicular & dorsal fat pad
  • Buffalo hump (diagnostic)
  • Moon Facies due to deposition in the cheeks and temporal area of the face, with a fish-like mouth.
  • Purple striae due to decreased proteins in the collagen fibres. This causes the collagen fibres to tear easily and leads to the formation of purple striae.
  • Thin skin.
  • Capillary fragility & easy bruising.
  • Hirsutism (excess facial hair growth) and acne vulgaris–due to increased androgens.
  • Hb percentage is raised.
  • Depression and psychosis.
  • Diabetes Mellitus also called Adrenal Diabetes.
  • Severe muscular weakness due to increased protein catabolism.
  • Thin extremities due to muscle wasting and protein catabolism. This leads to myopathy and inability of the patient to stand up from a sitting position.
  • Infections due to suppressed immune system with impaired wound healing.
  • Osteoporosis leading to frequent fractures.
  • Hypertension and hypokalemia - due to increased aldosterone.
  • Amenorrhoea.
diagnosis1
Diagnosis
  • Very challenging.
  • Diagnose excess Cortisol.
  • Dexamethasone suppression test: this test helps differentiate between ACTH-dependant and ACTH-independent Cushing’s syndrome.
  • Confirmation of cause.
treatment1
TREATMENT
  • Removal of the cause: Surgery of the adrenal tumour OR pituitary tumour.
  • Drugs that block steroidogenesis.e.g. Ketaconazole.
  • Drugs that inhibit ACTH secretion.e.g. Serotonin antagonists.
  • Partial or total adrenalectomy.

The treatment is followed by administration of adrenal steroids to make up for any insufficiency that may arise.

adrenogenital syndrome
DEFINITIONS:

It is a disorder caused by an occasional adrenocortical tumor secreting excessive quantities of androgens that cause intense masculinizing effects throughout the body.

Adrenogenital syndrome
signs symptoms2
SIGNS & SYMPTOMS

IN FEMALES

IN MALES

Precocious development in boys.

In prepubertal male, a virilizing adrenal tumour causes same characteristics as in the female plus rapid development of the male sex organs.

In adult male, the virilising characteristics are often masked by the virilising effects of Testosterone.

Diagnosis is made by the presence of excess 17-ketosteroids in the urine.

  • Virile characteristics in women & girls.
  • Hirsutism: hair on the face, chin and upper lips.
  • Deeper voice.
  • Occasionally baldness.
  • Masculine distribution of hair on the body.
  • Deposition of proteins in a masculine manner.
