Calciphylaxis: Diagnosis, Pathogenesis, and Treatment

Area of Science:

• Dermatology and Nephrology
• Vascular Biology
• Pathophysiology

Background:

• Calciphylaxis is a severe condition characterized by ischemic skin necrosis due to calcific uremic arteriolopathy.
• It predominantly affects patients with end-stage renal disease and other risk factors.
• Current management focuses on risk factor modification and wound care, with limited therapeutic options.

Purpose of the Study:

• To review the current understanding of calciphylaxis.
• To detail its pathogenesis, clinical presentation, diagnostic methods, and treatment strategies.
• To highlight emerging therapeutic targets.

Main Methods:

• This article is a narrative review.
• It synthesizes information from existing literature on calciphylaxis.
• The review covers pathogenesis, clinical features, diagnosis, and treatment.

Main Results:

• Calciphylaxis results from vascular calcification leading to occlusion and ischemic infarcts.
• Clinical features include painful, non-healing ulcers and necrotic lesions.
• Diagnosis relies on clinical suspicion, biopsy, and imaging, though often challenging.

Conclusions:

• Calciphylaxis requires a multidisciplinary approach for management.
• While risk factor control and wound care remain crucial, novel therapeutic strategies targeting underlying mechanisms are emerging.
• Further research is needed to establish effective treatments for this devastating condition.
