Blueprint for a European calciphylaxis registry initiative: the European Calciphylaxis Network (EuCalNet)

Area of Science:

• Nephrology
• Dermatology
• Rare Diseases

Background:

• Calcific uraemic arteriolopathy (CUA) presents diagnostic and therapeutic challenges.
• Characterized by painful skin lesions, medial calcification of arterioles, and matrix remodeling.
• Epidemiology and risk factors for CUA remain incompletely understood.

Purpose of the Study:

• To establish an internet-based registry for collecting comprehensive data on CUA patients.
• To enhance understanding of CUA epidemiology, clinical presentation, and management.
• To lay the groundwork for future prospective controlled trials in CUA.

Main Methods:

• An internet-based registry (www.calciphylaxie.de) was created in Germany for CUA patient notification.
• A comprehensive database collects over 70 parameters including patient data, lab results, and treatment strategies.
• Expansion to an international registry (www.calciphylaxis.net) via the EuCalNet initiative is planned.

Main Results:

• The German registry has provided valuable experience in data collection for CUA.
• The EuCalNet initiative will facilitate multinational data collection on this rare disease.
• The registry data will offer insights into CUA's epidemiology and clinical characteristics.

Conclusions:

• Internet-based registries are crucial for advancing knowledge of rare diseases like CUA.
• EuCalNet aims to consolidate international efforts in CUA research.
• This initiative may facilitate the development of evidence-based therapeutic strategies for CUA.
