Objectives

Narrative objectives1

Giltelman syndrome (GS) is a recessive salt-losing tubulopathy of children or young adults caused by a mutation of genes encoding the human sodium chloride cotransporters and magnesium channels in the thiazide-sensitive segments of the distal convoluted tubule. The plasma biochemical picture is characterized by hypokalemia, hypomagnesemia, hypocalciuria, metabolic alkalosis and hypereninemic hyperaldosteronism.
The prognosis of GS is generally good, but a few patients may be at risk of developing cardiac arrhythmias. Patients with severe hypokalemia are susceptible to cardiac arrhythmias, which may even be life threatening, when joined with severe hypomagnesemia and alkalosis.
And the patients need to take large amounts of potassium and magnesium for life.
There is no reliable simple load test, genetic testing is useful in doubtful cases.
