Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Calciphylaxis, also called Calcific Uremic Arteriolopathy (CUA) is a lethal affection mostly affecting patient in end stage renal disease. The survival rate is described around 20 to 46% at one year.

Clinical presentation is very painful skin lesions with ulceration mostly located on the trunk or thigh.

Current knowledge about physiopathology, diagnostic practice and therapeutic is very limited.

Actually there is no European study about calciphylaxis and risk factors, diagnostic practice and outcome factors.

Calciphylaxis Cases

Adult patients with advanced chronic kidney disease (DFG estimation \< 30 ml/min/1.73m² - beyond 3B stage) with/without substitute therapy who has presented a case of calciphylaxis (Calcific Uremic Arteriolopathy) between 2006 and 2016 in the Regions of Pays de la Loire, Centre Val de Loire, Bretagne and Poitou-Charentes

Calcific Uremic Arteriolopathy
