    Abstract:
    BACKGROUND: Calciphylaxis is a rare but life-threatening condition occasionally affecting patients with secondary hyperparathyroidism. Parathyroidectomy has been advocated as the only potentially curative intervention. METHODS: Between January 1989 and May 2000, 13 patients with pathologic/clinical criteria of calciphylaxis were treated at our institution. Of these 13 patients, 7 were managed with medical therapy alone, and 6 were referred for parathyroidectomy. The medical records were reviewed, and patients/relatives were interviewed. RESULTS: All patients had cutaneous wounds requiring local debridement predominantly located on the lower extremities or abdominal wall. Six patients underwent subtotal (3.5 gland) parathyroidectomy without morbidity. All 6 had significant reductions in parathyroid hormone levels after surgery (mean decrease, 94% +/- 0%), and all reported resolution of pain and healing of cutaneous wounds. Of the remaining 7 patients who had medical management alone, 5 eventually died of complications related to calciphylaxis. In comparing the 2 groups, patients who underwent parathyroidectomy had a significantly longer median survival than those who did not have surgery (36 vs 3 months, P =.021). CONCLUSIONS: Calciphylaxis frequently causes gangrene, sepsis, and eventual death. Parathyroidectomy can be performed with minimal morbidity and is associated with resolution of pain, wound healing, and a significantly longer median survival. Therefore, patients with secondary hyperparathyroidism and signs/symptoms of calciphylaxis should be referred promptly for consideration of parathyroidectomy.
