- Hyponatremia, hyperkalemia, hypercalcemia and eosinophilia
Clinical presentation for chronic adrenal insufficiency (5)
- Fatigue, weakness and anorexia
- GI (N/V, abd pain)
- Weight loss
- Hyper pigmentation or vitiligo

How to diagnose adrenal insufficiency
- measure ACTH and Serum cortisol with high-dose (250microgram) ACTH stimulation test
What do you expect to see in primary adrenal insufficiency during ACTH stimulation test
low cortisol
high ACTH
What do you expect to see in secondary adrenal insufficiency during ACTH stimulation test
low cortisol
low ACTH
what acid-base imbalance is seen in Primary adrenal insufficiency (Addison disease)?
normal anion gap metabolic acidosis

>100 urine osmolality &
Urine sodium <25 (3)
- Volume depletion
- CHF
- Cirrhosis
Causes of Hyponatremia with
<290 serum osmolarity
>100 urine osmolality &
Urine sodium >25 (3)
- SIADH
- Adrenal insufficiency
- Hypothyroidism
- 5 days of URI
- Young adult men (20-30)
- Recurrent gross hematuria
IgA nephropathy
- 10-21 days after URI
- Children (6-10)

IgA nephropathy
- Low C3 complement
- Elevated anti-streptolysin O &/or anti-DNAse B
- Kidney biopsy with subepithelial humps consisting of C3 complement
Post-infectious glomerulonephritis
What lab value differentiates Familial hypocalciuric hypercalcemia (FHH) with primary hyperparathyroidism?
Urinary calcium level
High serum Calcium
High serum PTH
Low urinary calcium

High serum Calcium
High serum PTH
High urinary calcium
Primary Hyperparathyroidism
