Overview
Pathophysiology
- Bartter syndrome is a renal tubular salt-wasting disorder in which the kidneys cannot reabsorb sodium and chloride in the thick ascending limb of the loop of Henle.
- Impairment of sodium and chloride reabsorption is the primary defect in the Bartter syndrome that initiates the cascade.
- This leads to increased delivery of salt to the distal tubules and hence, results in excessive salt and water loss from the body. The resultant volume depletion causes activation of the renin-angiotensin-aldosterone system (RAAS) and subsequent secondary hyperaldosteronism. Long-term stimulation causes hyperplasia of the juxtaglomerular apparatus and elevates renin levels.[1][2]
