Abstract

Background: Subcutaneous fat necrosis (SCFN) of the newborn is an uncommon disorder that occurs in the first weeks of life after foetal distress. It can be complicated by potentially life-threatening hypercalcemia. Treatments of hypercalcemia have included hydration, furosemide and corticosteroids. Only one report has described the use of intravenous bisphosphonates for this condition. We propose that pamidronate could be the first line therapy for severe hypercalcemia in SCFN. Patients and Results: Four newborns presented between 2001 and 2004 with SCFN complicated by severe hypercalcemia. At diagnosis, ionized calcium levels were higher than 1.4 mmol/l and were associated with high urinary calcium/creatinine ratios and high 1,25-dihydroxyvitamin D levels. Despite treatment with IV fluids, low calcium diet and furosemide, calcium levels remained high. The patients were given 3–4 doses (0.25–0.50 mg/kg/dose) of pamidronate. Urinary calcium/creatinine ratios and calcium levels decreased within 48–96 h. 1,25-dihydroxyvitamin D levels normalized with resolution of the skin lesions. No persistent nephrocalcinosis was observed. Conclusion: Pamidronate is effective, well-tolerated in the short-term and obviates the need for prolonged treatment with furosemide and corticosteroids. To prevent nephrocalcinosis, pamidronate might be considered as first line treatment for severe hypercalcemia in SCFN.
