Addisons disease Flashcards
Addisons Disease etiology
Death is usually due to adrenal hemorrhage or due to other chronic condition superimposed.
History of Addison’s Disease
andrenocortical Insufficiency
Dr. Thomas Addison
* insufficient amount of secretion of ATH to meet the body’s need which leads to decreased amount of cortisol and aldosterone
Elevated ACTH
ALL LAYERS OF THE ADRENAL IS DESTROYRF.*
Addisons - Idiopathic autoimmune affects females and Children more
MOST COMMON AGE 30-50
AP
Onset 90% destruction of adrenal cortex
Elevated levels of ACTH
Hyper pigmentation
Mineral corticoids deficiency
Increase sodium loss via kidneys, ins trying retention to potassium, hypoextracellular
Addisons Causes
Idiopathic (most)
Tuberculosis and histoplasmosis
Therapeutic use of corticosteroids
Sudden sensation of exogenous adrendocorticod hormone theraphy
Addison Clinical manifestation
Muscle W. Fatigue Anorexia Emaciation HYPERPIGMENTATION HYPOTENSION HYPOGLYCEMIA HYPONATREMIA HYPERKALEMIA severe chronic dehydration Emotional disturbances confusion weak rapid pulse decrease urine output
Addison Clinical manifestation
Onset insidious and non specific
Vitiligo
GI- N/V occasional diarrhea - steatorrhea
Orthostasis my progress to syncope
Myalgia so flaccid muscle paralysis (hyperkalemia)
Impotence decreased libidos
Amenorrhea secondary to weight loss
Addison Hypotension
Less than 120/60
Addison hypoglycemia
< 40 in female
< 50 in male
HyPERkalemia
More than 5.0
Hyponatremia
Less than 136 (135)
Plasma cortisol test
Performed on patients who are suspected of having hyper and hypo function of Adrenal glands blood is collected at two separate times and the blood is compared
ACTH Stimulation Test
Evaluates ability of adrenal glands to respond to administration on ACTH
*Determines cause of adrenal deficiency
3 types - rapid, 24hr, 3 day test
NPO after MIDNIGHT day before test
After test : monitor VP site and apply pressure
ACTH
RAPID
- Obtain baseline cortisol level 30 minutes prior to cosyntropin admin
- Admin IV cosyntropin over a 2 min period (may be given IM)
- Measure Plasma level 30-60 min post admin
ACTH
24hr
Baseline
IV infusion of Cosyntropin over 24hours
Measure plasma level
ACTH
3 day test
- Baseline
- IV cosyntropin over 8 hours 3 days consecutively
- Measure plasma level 12, 24, 36, 48, 60, 72 after start of test.
ACTH STIMULATION TEST RESULTS
ELEVATED LEVEL OF ACTH WITH low level of cortisol and indicative of Addison
If ACTH IS GREATER THAN 80
And Cortisol less than 5
ATCH exaggerated response
Secondary and renal insufficiency and Cushing syndrome
ACTH normal or below response
Primary adrenal insufficiency Cushing syndrome
ADDIsonian Crisis
Episode of Acute hyPOtension developing from inadequate fluid volume
Addisonian Crisis
Causes
Severe emotional stress Extreme temperatures Overexertion Trauma or Surgery Dehydration Infections Abrupt withdrawals of exogenous steroid treatment
Clinical manifestations of Addisonian Crisis
Pallor Abdominal pain Apprehension confusion Weak pulse. restlessness rapid restorations Headache Fever Risk for circulatory collapse nausea/ Diarrheas
Immediate treatment of Addisonian Crisis
Goal: PREVENT SHOCK IV fluids Dextrose 5% NS Recumbent position Iv Solu Corteff Vasopressors antibiotic as needed Resume oral intake as soon as possible Increase sodium in diet when GI losses are excessive
Emergency interventions for Addisons
- Increase salt intake under conditions of increased stress and sodium losses
- pre-filled corticosteroid injection
- Medical Alert Jewelry
Deltasone (Prednisone)
Glucocorticoids
4 times more potent than naturally occurring cortisol longer anti inflammatory actions (some mineralocotioid properties
CONTROLS PREVENTS INFLAMMATION BY CONTROLLING THE RATE OF PROTEIN SYNTHESIS AND REVERSING CAPILLARY PERMEABILITY. Metabolized in the liver…. And excreted by the kidneys
Deltazone (Prednisone) Side Effects
^ appetite, weight gain
CV: bradycardia, arrhythmias, cardiac enlargement, CHF, CC, PE, cardiac arrest
Decreased carb tolerance abnormal fat deposits (cushings) DM menstrual irregularities moon fact Secondat and pituitary unresponsiveness
Acne, allergic dermatitis
fluid retention, hyper tension, hypokakemia
CorTEF
Hydrocortisone
Structurally identical to endogenous cortisol
Drug of choice for Addison
PO/IV for Addison
Controls prevents inflammation by controlling the rate of protein synthesis and recasting capillary permeability
Metabolized by the liver and excreted in the urine
Cortef HyDrocortisone side effects
Insomnia Indigestion
Increased appetite Hirutism arthralgia cataract epistaxis DM, Adrenal suppression psychosis, vertigo, osteoporosis, delayed wound healing
Florinef
(Fludrocortisone)
Corticosteroid
Promotes increase re absorption of sodium and excretion of potassium from the renal distal tubules
FlorineF side effects
Diabetes insipidus, DM adrenal suppression delayed wound healing Gi perforation glucose intolerance, hepatomegaly, hypokalemic alkalosis menstrual irregularity, pituitary adrenal axis suppression psychosis seizure ulcerative esophagitis hypertension cardiomegaly
