Acquired Gitelman Syndrome Associated with Systemic Sclerosis

Gitelman syndrome is an inherited renal disorder characterized by hypomagnesemia, hypokalemia, hypocalciuria and metabolic alkalosis linked to the genes encoding the thiazide sensitive NaCl cotransporter (NCCT) located on the distal convoluted tubule of the kidney. It usually presents in late childhood or early adulthood with electrolyte abnormalities resembling chronic thiazide diuretic use. Acquired Gitelman syndrome is a very rare disorder mostly associated with Sjogren’s syndrome.
