Severe Hypocalcemia after Intravenous Bisphosphonate Therapy in Occult Vitamin D Deficiency

N Engl J Med 2003; 348:1503-1504April 10, 2003

Article

To the Editor:

Oral bisphosphonates are effective for the prevention and treatment of osteoporosis. Powerful second- and third-generation parenteral bisphosphonates, including pamidronate and zoledronate, are also available for off-label use. Although rarely observed, mild hypocalcemia has been reported with this class of agents.1 On the other hand, osteomalacia, as a result of vitamin D deficiency, is common, especially in elderly persons and those with malabsorptive states such as those due to gastric bypass, nontropical sprue, and cystic fibrosis.2 A recent case illustrates a serious complication of bisphosphonate use in a patient with coexisting but occult osteomalacia.

A 52-year-old woman presented with rib and foot pain. Menopause had occurred at the age of 50. The patient had undergone gastric stapling in 1987 and a Roux-en-Y procedure in 2001 for morbid obesity. Serum calcium and phosphorus levels were normal. The T score for bone mineral density at the hip was –1.7. A bone scan showed multiple areas of uptake in the ribs and feet but no fractures. Pamidronate (60 mg) was administered intravenously over a period of four hours. Three weeks later, the patient presented with tetany and rapid atrial fibrillation. The serum calcium level was 4.8 mg per deciliter (normal range, 8.5 to 10.0). The serum 25-hydroxyvitamin D level was 7 ng per milliliter (normal range, 9 to 55); the parathyroid hormone level was more than 300 pg per milliliter (normal range, 10 to 65), and the alkaline phosphatase level was four times the normal value. Intravenous and oral calcium, as well as dihydrotachysterol (0.4 mg twice daily), was administered for seven days. One month after admission, the serum calcium level was 7.0 mg per deciliter; four months after admission, the serum calcium level was 7.9 mg per deciliter; the serum 25-hydroxyvitamin D level was 15 ng per milliliter. Discontinuation of dihydrotachysterol and the addition of ergocalciferol (50,000 units three times per week) for two months and 4 g of oral calcium per day increased the serum calcium level to 8.6 mg per deciliter and increased the serum 25-hydroxyvitamin D level to 27 ng per milliliter. The patient's symptoms resolved completely.

In this patient, subclinical osteomalacia due to vitamin D deficiency, coupled with the administration of a potent intravenous bisphosphonate, resulted in severe, life-threatening hypocalcemia. Pamidronate is a potent inhibitor of bone resorption; as such, it slows calcium efflux from the skeleton. In the face of inadequate vitamin D due to gastrointestinal malabsorption and concurrent pamidronate use, the serum calcium level cannot be maintained in the normal range. Patients with osteoporosis should be prescreened for vitamin D deficiency, and those with such a deficiency should receive vitamin D–replacement therapy before intravenous bisphosphonate therapy is considered.
