Managing Calciphylaxis: Insights from Real-World Cases at a Tertiary Academic Center

Area of Science:

• Vascular Medicine
• Dermatology
• Nephrology

Background:

• Calciphylaxis is a rare, severe condition characterized by microvascular calcification leading to chronic, nonhealing wounds.
• The lack of approved treatments underscores the need for effective diagnostic and management strategies.
• Patient quality of life is significantly impacted by the devastating effects of calciphylaxis.

Purpose of the Study:

• To highlight potential misdiagnoses of calciphylaxis in a patient cohort.
• To emphasize the importance of accurate diagnosis through multidisciplinary approaches.
• To discuss diagnostic challenges and risks associated with tissue biopsy in calciphylaxis.

Main Methods:

• A case series of three patients treated at a tertiary academic center between March 2021 and March 2023.
• Patients received varied treatments including local wound care, sodium thiosulfate, medication adjustments, lymphedema therapy, pulse lavage, and cadaveric skin substitute.
• Tissue biopsy was performed in two patients to aid diagnosis, revealing associated challenges.

Main Results:

• The case series illustrates diagnostic difficulties in identifying calciphylaxis.
• Biopsies, while aiding diagnosis, presented challenges and risks.
• Effective management requires a high index of clinical suspicion, considering patient history, presentation, and risk factors.

Conclusions:

• Accurate diagnosis of calciphylaxis is paramount and relies on clinical suspicion.
• Multidisciplinary management is essential for addressing calciphylaxis.
• Key treatment goals include wound care, infection and pain management, and close patient monitoring.
