Renal wasting of magnesium and phosphate.
We report an asymptomatic man found to have simultaneous renal transport defects for magnesium and phosphate. Associated findings include gout, high frequency hearing loss, chronic elevations of SGOT and SGPT, metabolic bone disease, and hyperparathyroidism. The clinical expression of hyperparathyroidism was masked for 5 years by hypomagnesemia, and the patient became hypercalcemic only when magnesium levels were normalized by intravenous infusion. Both the phosphate and magnesium transport abnormalities persisted after parathyroidectomy. The many unique features of this case distinguish it from previously described disorders of magnesium or phosphate wasting.
