Overview

Hypoaldosteronism must be differentiated from other diseases that cause hypotension and muscle weakness such as Addison's disease, myopathies, celiac disease, Peutz-Jeghers syndrome, anorexia nervosa, syndrome of inappropriate anti-diuretic hormone (SIADH), neurofibromatosis, porphyria cutanea tarda, salt-depletion nephritis and bronchogenic carcinoma. In addition, measurement of plasma renin activity (PRA), serum aldosterone, and serum cortisol is used to differentiate among various subtypes of hypoaldosteronism.

Differentiating Hypoaldosteronism from other Diseases

  • Various subtypes of hypoaldosteronism can be differentiated on the basis of plasma renin activity (PRA), serum aldosterone, and serum cortisol. These tests are performed after maintaining an upright position for three hours. Under normal conditions, maintaining an upright position for long duration activates the neurohormonal regulation by the kidneys which leads to increased renin and aldosterone release.
  • The following table distinguishes among various subtypes of hypoaldosteronism:
Disorder Plasma ReninActivity Plasma Aldosterone Plasma cortisol
Hyporeninemic hypoaldosteronism Low  Low  Normal
Hypereninemic hypoaldosteronism Increased Low  Normal/↓
Primary adrenal insufficiency High Low  Low 
Pseudohypoaldosteronism type I High High Normal
Pseudohypoaldosteronism type II Normal/↓ Normal/↓ Normal
Disease Differentiating symptoms Differentiating laboratory findings Gold standard test
Hypotension Abdominal pain Anorexia/

weight loss

Muscle weakness Hypoglycemia Skin pigmentation Other symptoms Hyponatremia Cortisol levels Other labs
Addison's disease + + + + + + - Low ACTH stimulation test
Myopathies

(polymyositis,

hereditary myopathies)

- - - + - Heliotrope rash and

Gottron's sign

- Normal - Muscle biopsy
Celiac disease - + + - - Dermatitis herpetiformis  - Normal - Abnormal small bowel biopsy
Syndrome of inappropriate anti-diuretic hormone

(SIADH)

- - - - - - - + Normal Water deprivation test
Neurofibromatosis - - + + - Axillary- and inguinal-area freckling - - - Biopsy of skin tissue
Peutz-Jeghers syndrome + + - Normal Colonic imaging showing the small intestinal polyps
Porphyria cutanea tarda - + - - - Blisters on sun-exposed sites - Normal or elevated High level of porphyrins in the urine
Salt-depletion nephritis + Flank pain - - - - + Elevated <15:1 BUN:CR
Bronchogenic carcinoma - - + - - + - Elevated Increased ACTH and

Hypokalemia

Cytological or histological evidence of lung cancer in sputum, pleural fluid, or tissue
Anorexia nervosa + - + + + - - Elevated - Psychiatric condition
