LDL-apheresis dramatically improves generalized calciphylaxis in a patient undergoing hemodialysis.

We present the first documented case of generalized calciphylaxis that dramatically improved after low-density lipoprotein-apheresis (LA) in a patient undergoing long-term hemodialysis. Calciphylaxis was diagnosed by skin biopsy and was manifest as painful ulcers on the right leg, left buttock, and glans penis. Skin perfusion pressure (SPP), which has recently been used as an indicator of impaired capillary perfusion in distal lesions of the lower extremities, was markedly reduced. The ulcers continued to worsen despite general wound care, correction of levels of calcium × phosphate product, hyperbaric oxygen therapy, and use of bisphosphonate, antiplatelet therapy, and vasodilators. Because LA is known to exert favorable effects on peripheral arterial disease through improved hemorheology, anti-inflammatory action, vasodilation, and angiogenesis, we introduced LA to produce the same effects on calciphylaxis. LA dramatically increased SPP and promoted ulcer healing, demonstrating that LA can be a useful treatment option for calciphylaxis.
