ABSTRACT
Calciphylaxis is a small vessel vasculopathy with medial calcification associated with intimal proliferation, fibrosis and thrombosis. This study discusses the clinical features and treatment of calciphylaxis and assesses the prognosis of patients with calciphylaxis. All patients admitted to vascular or renal wards from January 2003 to December 2004 at Royal Perth Hospital, with diagnosis of calciphylaxis confirmed histologically were included in the study. Five patients were included in the study; four male and one female. Three patients had end stage renal failure on haemodialysis and two had normal renal function. All three patients with end-stage renal failure had secondary hyperparathyroidism associated with elevated parathormone and corrected ionised calcium. The two patients with normal renal function had normal calcium, phosphate, and parathormone levels. The diagnosis of calciphylaxis was confirmed in all patients. The wounds of four patients healed and one patient died 8 months after the diagnosis of calciphylaxis had been made. Calciphylaxis is a condition mostly present in patients with end-stage renal failure and can occur in patients with normal renal function. It usually carries a poor prognosis, but in this small series the outcome of patients was good with satisfactory healing of wounds.
