Calciphylaxis is an uncommon condition that affects 1-4% of the population with ESRD. [30, 31] A concern exists that the incidence has increased during the last decade because of a number of possible factors, including more widespread use of parenteral vitamin D and iron dextran. No good data are available regarding the incidence of calciphylaxis in the general population without ESRD, but it is even less common. Nonuremic disease is being identified more commonly, especially in patients with rapid weight loss. Some cases are associated with warfarin use, but that association does not appear to alter prognosis. [32]
