Filter by:Calciphylaxis, a vascular calcification disorder, is a rare and serious disorder characterized by calcification of dermal arterioles. There are significant gaps in the understanding of the pathophysiology and risk factors for calciphylaxis. At present, there is no effective treatment. Uncertain pathobiology, rare incidence and lack of collaborative approach have been some of the major limiting factors towards treating calciphylaxis. The Partners Calciphylaxis Biorepository (PCB) aims to address these gaps within calciphylaxis research by utilizing existing and, when necessary, developing new infrastructure to support the consent of patients and the collection of dedicated samples for a calciphylaxis repository.
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.
To evaluate the effect of SNF472 on top of standard of care on promoting wound healing and other parameters of therapeutic response in haemodialysis patients with calciphylaxis (calcific uraemic arteriolopathy, CUA).
Observational, registry, prospective, non-interventional collection of CUA patient data. Patient treatment is carried out within clinical routine, at the discretion of the physicians and according to existing treatment guidelines. Participating physicians will not be subject to any instructions with regard to the diagnosis and therapy of their patients.
To evaluate the efficacy of Sodium Thiosulfate (STS) compared to placebo, in reducing analgesic requirement in subjects with calcific uremic arteriolopathy (CUA) during an initial 28-day treatment phase.
Calcific uremic arteriolopathy a.k.a. calciphylaxis is a vascular calcification disorder seen in dialysis patients. Calcific uremic arteriolopathy has 60-80% one-year mortality and significant morbidity associated with non-healing and extremely painful skin lesions. At present, there is no effective treatment for calcific uremic arteriolopathy. Vitamin K is an important vitamin for inhibiting vascular calcification. It is known to increase the circulating levels of carboxylated Matrix Gla Protein, a potent inhibitor of vascular calcification. However, the effects of vitamin K supplementation in patients with calcific uremic arteriolopathy are unknown. The purpose of this study is to conduct a pilot randomized controlled trial to examine the effects of oral vitamin K supplementation on circulating levels of anti-calcification factor (carboxylated Matrix Gla Protein) and clinical outcomes in patients with calcific uremic arteriolopathy.
Martorell hypertensive ischemic leg ulcer is a severe type of skin necrosis (skin infarction) which occurs in long-term hypertensive subjects. Calciphylaxis (calcific uremic arteriolopathy) is a severe type of skin necrosis (skin infarction) which occurs in subjects with end-stage kidney disease or after kidney transplantation.
The research question and primary aim is to determine if lanthanum carbonate is effective in treating calciphylaxis by measurement of complete or partial remission of skin lesions. Secondary endpoints will be measured to determine if lanthanum carbonate can lower calcium-phosphorus product levels, intact PTH and mortality. Albumin levels will be measured as a marker of nutritional status and inflammation.
