Description Caicific uremic arteriolopathy or calciphylaxis is a rare disorder characterized by systemic medial calcification of arterioles that leads to ischemia and subcutaneous necrosis. It most commonly occurs in patients with end-stage renal disease who are on haemodialysis or who have received a renal transplant. Calciphylaxis is dangerous by its fast progression into tissue necrosis, difficult healing process and a great risk of secondary infection which is the most common cause of death in this condition. The reported mortality rates are as high as 60-80 % in a couple of months once it is diagnosed. The key to successful treatment of calciphylaxis is fast diagnosing of the disease and appropriate treatment management. On the examples of three patients from our haemodialysis centre we demonstrate typical clinical manifestation of calciphylaxis and its treatment, which requires close patient-medical staff cooperation. The basic principle of treatment of all our patients was normalization of calcium-phosphate metabolism and secondary hyperparathyroidism. Sodium thiosulfate had been administered to all patients at the end of haemodialysis session. The wound care played another major role with gentle debridement and intensive local care. After five to six months the skin defects resolved in the first patient, partially resolved in the second patient and deteriorated in the third patient. We have observed no side effects of sodium thiosulfate application.
