The loss of this cotransporter leads to excretion of sodium, potassium, and chloride in the urine, as well as excessive loss of extracellular water. The depletion of extracellular water then leads to activation of the&nbsp;<a href=\"https:\/\/www.osmosis.org\/learn\/Renin-angiotensin_aldosterone_system\" target=\"_blank\" rel=\"noreferrer noopener\">renin-angiotensin-aldosterone system<\/a>, which prompts the excretion of hydrogen and more potassium, as well as the reabsorption of bicarbonate. Therefore, common laboratory findings in patients with Bartter syndrome include&nbsp;<a href=\"https:\/\/www.osmosis.org\/learn\/Metabolic_alkalosis\" target=\"_blank\" rel=\"noreferrer noopener\">metabolic alkalosis<\/a>&nbsp;and hypokalemia. Despite the loss of sodium through the urine, there is no&nbsp;<a href=\"https:\/\/www.osmosis.org\/learn\/Hyponatremia\" target=\"_blank\" rel=\"noreferrer noopener\">hyponatremia<\/a>, due to the concomitant loss of water.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The thick ascending limb of the loop of Henle is also responsible for calcium reabsorption via an electrochemical gradient created by the reabsorption of sodium, potassium, and chloride. As a result, patients with Bartter syndrome commonly present with&nbsp;<a href=\"https:\/\/www.osmosis.org\/learn\/Hypercalcemia\" target=\"_blank\" rel=\"noreferrer noopener\">hypercalciuria<\/a>. Also, due to increased reabsorption of urate and general volume depletion, patients may also present with&nbsp;<a href=\"https:\/\/www.osmosis.org\/learn\/Lesch-Nyhan_syndrome\" target=\"_blank\" rel=\"noreferrer noopener\">hyperuricemia<\/a>&nbsp;with or without&nbsp;<a href=\"https:\/\/www.osmosis.org\/learn\/Gout\" target=\"_blank\" rel=\"noreferrer noopener\">gout<\/a>.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">https:\/\/osmosis.org\/embed\/Loop_of_Henle<br>It is also worth noting that loop diuretics act by blocking the same cotransporter in the thick ascending limb of the loop of Henle. Therefore, patients with Bartter syndrome present similarly to those with chronic&nbsp;<a href=\"https:\/\/www.osmosis.org\/learn\/Loop_diuretics\" target=\"_blank\" rel=\"noreferrer noopener\">loop diuretic<\/a>&nbsp;use.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Major_takeaways\"><\/span>Major takeaways<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Bartter syndrome is a renal tubular defect that is caused by an autosomal recessive mutation of the Na+\/K+\/2Cl- cotransporter in the thick ascending limb of the loop of Henle. Common laboratory findings in patients with Bartter syndrome include metabolic alkalosis, hypokalemia, hypercalciuria, and hyperuricemia. Patients present similarly to those with chronic use of loop diuretics, and the hyperuricemia may cause symptoms consistent with gout.&nbsp;<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"References\"><\/span><strong>References<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<ul class=\"wp-block-list\">\n<li><a href=\"https:\/\/www.indianjnephrol.org\/article.asp?issn=0971-4065;year=2010;volume=20;issue=4;spage=207;epage=210;aulast=Sampathkumar\" target=\"_blank\" rel=\"noreferrer noopener\">Childhood Bartter&#8217;s syndrome: An Indian case series<\/a>.<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\"><strong><em>_________________________<\/em><\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong><em>Want more USMLE\u00ae Step 1 practice questions?
