Calciphylaxis in end-stage liver and renal disease patients before and after transplant

Area of Science:

• Vascular Medicine
• Nephrology
• Hepatology

Background:

• Calciphylaxis is a rare, severe vascular disorder.
• Characterized by arteriole calcification, inflammation, and tissue necrosis.
• Associated with end-stage renal disease (ESRD) and cirrhosis, with high mortality (45-80% 1-year).

Purpose of the Study:

• To review the challenges in managing calciphylaxis.
• To discuss the role of kidney transplantation in calciphylaxis treatment.
• To highlight the complexities of simultaneous liver-kidney (SLK) transplantation for patients with calciphylaxis.

Main Methods:

• Literature review of calciphylaxis cases.
• Analysis of treatment outcomes and transplant considerations.
• Discussion of diagnostic criteria and clinical presentation.

Main Results:

• Calciphylaxis presents as black eschars and retiform purpura, diagnosed via skin biopsy.
• Kidney transplant can be a successful therapy, but calciphylaxis can also occur post-transplant.
• Managing patients with ESRD/cirrhosis on transplant waiting lists is complex due to high mortality.

Conclusions:

• Effective management strategies for calciphylaxis, especially concerning transplantation, are still under investigation.
• Further research is needed to optimize donor allograft allocation for patients with calciphylaxis and comorbid ESRD/cirrhosis.
• The decision-making process for SLK transplant in calciphylaxis patients requires careful risk-benefit assessment.
