Hypocalcemia with hypoparathyroidism and renal tubular dysfunction associated with aminoglycoside therapy.
Seventeen patients with malignant disease developed a complex metabolic syndrome of 2-8 weeks' duration characterized by hypocalcemia, hypomagnesemia and hypokalemia following administration of the aminoglycoside group of antibiotics. Gentamicin, Tobramycin, Amikacin, and Sisomicin were all involved. Other features noted were hypoalbuminemia, hypophosphatemia, and hypouricemia. Low immunoreactive parathyroid hormone (i-PTH) levels in the presence of hypocalcemia and absence of hyperplastic changes in the parathyroid gland examined at postmortem confirmed a diagnosis of hypoparathyroidism. Immunoreactive calcitonin levels (i-CT) were not elevated. Renal tubular wasting of potassium and magnesium was documented in six patients and excessive urinary loss of sodium, phosphate, and uric acid was noticed. Twelve patients died before recovering from the metabolic stress and five patients developed progressive renal impairment. A possible potentiating action of chemotherapeutic agents, especially Adriamycin, is suggested.
