Introduction:

Gitelman syndrome is a renal tubule disease that involves hypokalaemic metabolic alkalosis, hypomagnesaemia and hypocalciuria. The musculoskeletal effects of Gitelman syndrome are common, including the development of chondrocalcinosis.

Clinical case:

A female patient with long-standing chondrocalcinosis associated with chronic hypomagnesaemia on treatment with calcium and magnesium. After the suspension of the treatment due to surgery, she presented with a generalised weakness, metabolic alkalosis, hypokalaemia, hypomagnesaemia and hypocalciuria, with final diagnosis of Gitelman syndrome. After re-introducing the treatment, she improved clinically, with electrolytes remaining stable.

Discussion

and conclusions: A proper diagnosis of this type of tubular diseases is essential because an adequate treatment avoids associated complications.
