What Is Bartter’s Syndrome?

Bartter’s Syndrome is a rare genetic disorder that affects the kidneys’ ability to reabsorb sodium, chloride, and potassium. This condition leads to an imbalance of electrolytes in the body, which can result in various health complications. Named after Dr. Frederick Bartter, who first described the syndrome in the 1960s, it is classified as a type of renal tubular acidosis. Understanding Bartter’s Syndrome is crucial for early diagnosis and effective management.

Types of Bartter’s Syndrome

Bartter’s Syndrome is generally categorized into two main types: classic Bartter’s Syndrome and Gitelman Syndrome. While both conditions share some similarities, they have distinct features and underlying causes.

• Classic Bartter’s Syndrome: This type typically presents in infancy or early childhood. It is characterized by a combination of hypokalemia (low potassium levels), metabolic alkalosis, and hyperreninemia (elevated renin levels).
• Gitelman Syndrome: Often diagnosed in late childhood or adulthood, Gitelman Syndrome is similar but usually less severe. It is associated with hypomagnesemia (low magnesium levels) and hypocalciuria (low calcium levels in urine).

Causes of Bartter’s Syndrome

Bartter’s Syndrome is primarily caused by genetic mutations that affect the transport proteins in the kidney tubules. These mutations disrupt the normal reabsorption of electrolytes, leading to the symptoms associated with the syndrome. The condition can be inherited in an autosomal recessive or dominant manner, depending on the specific genetic mutation involved.

Bartter’s Syndrome Symptoms

The symptoms of Bartter’s Syndrome can vary widely among individuals, but they often include:

• Frequent Urination: Individuals may experience polyuria, leading to increased urination.
• Dehydration: Due to excessive fluid loss, dehydration can occur, resulting in thirst and dry mouth.
• Muscle Weakness and Cramps: Low potassium levels can lead to muscle weakness, cramps, and fatigue.
• Growth Delays: In children, the condition may result in growth delays due to electrolyte imbalances.
• Metabolic Alkalosis: This condition can cause symptoms like muscle twitching, hand tremors, and confusion.
• Nephrocalcinosis: Some patients may develop kidney stones or calcium deposits in the kidneys, leading to further complications.
