Brief Summary

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

The investigators propose to set up a prospective randomized controlled trial to control the security and assess the efficacy of adjuvant treatment by rheopheresis in necrotizing-ulcered calciphylaxis in the hemodialysis population.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Calciphylaxis, also known as uremic calcifying arteriolopathy (UCA), is a rare disease that causes painful ischemic skin lesions due to microvascular calcification and thrombosis of the dermis and subcutaneous adipose tissue. Patients with end-stage renal disease (ESRD) are the main target for calciphylaxis. Rheopheresis is a therapeutic apheresis to treat microcirculatory disorders. This double filtration plasmapheresis eliminates a defined spectrum of high molecular weight proteins from human plasma including relevant factors for vascular inflammation and thrombose. The investigators propose a prospective randomized controlled trial to compared the efficacy of rheopheresis as adjuvant treatment to the standard of care compared to standard care with Sham-apheresis.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Rheopheresis group

In addition to the standards of care, the experimental group will carry out the rheopheresis in two stages:

* Stage 1: induction treatment: 3 apheresis sessions during the first week (w0; i.e. between D1 and D7) and then 2 apheresis sessions each week for 3 weeks (from w1 to w3; i.e. between D8 and D28) ;
* Step 2: maintenance treatment with 1 apheresis session per week until the 11th week (i.e. between D29 and D84).

Group Type EXPERIMENTAL

Rheopheresis procedure

Intervention Type PROCEDURE

rheopheresis is performed using an automated monitor (Plasauto, company HemaT) in a double-filtration cascade. Plasma purify from of high molecular weight proteins

Sham-apheresis group

In addition to the standards of care, the comparator group will carry out Sham-apheresis sessions according to the same scheme as the rheopheresis sessions of the experimental group.

Group Type SHAM_COMPARATOR

Sham-apheresis

Intervention Type PROCEDURE

Sham-apheresis is performed with the same automated monitor (Plasauto, HemaT company). Extracted plasma is not treated through the secondary filter (Rheofilter) and return to the patient.
