Official title
Partners Calciphylaxis Biobank and Patient Registry
Overview
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.
Detailed description
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.
This repository is working in collaboration with the Partners Biobank as they will still be receiving samples from the PCB and storing them and distributing them according to their own procedures.
Primary outcome measures
- Number of patients with improvement in calciphylaxis skin lesions [Time frame: 6 months]
Secondary outcome measures (2)
- Number of patients with >30% improvement in pain severity [Time frame: 4weeks]
- Time to death in patients with calciphylaxis [Time frame: Up to 5 years]
Eligibility criteria
Inclusion criteria
- Male or female ≥18 years old
- Skin lesions consistent with calciphylaxis diagnosis as determined by the treating clinician

Exclusion criteria
- Patients <18 years of age
- Prisoners
Criteria are shown verbatim from the registry (in English). Final eligibility is always assessed by the study center.
