A RARE CLINICAL PRESENTATION: A PATIENT WITH CHRONIC RENAL FAILURE, SECONDARY HYPERPARATHYROIDISM AND CALCIPHYLAXIS

Area of Science:

• Nephrology
• Endocrinology
• Vascular Biology

Background:

• Calciphylaxis, or calcific uremic arteriolopathy (CUA), is a rare but serious complication in patients with chronic renal failure and secondary hyperparathyroidism.
• CUA involves progressive vascular degeneration leading to ischemic tissue loss, potentially causing sepsis, organ failure, and death.
• The exact pathogenesis is unclear but involves increased calcification activators like oxidized LDL, TNF-α, and calcitriol.

Observation:

• This case report details an end-stage renal failure patient with coexisting hyperparathyroidism, hyperthyroidism, and calciphylaxis.
• The patient presented with characteristic cutaneous manifestations of calciphylaxis.

Findings:

• Treatment focused on managing the underlying pathologies and normalizing serum calcium and phosphorus levels.
• Surgical removal of the parathyroid gland (parathyroidectomy) was performed.

Implications:

• Cutaneous manifestations of calciphylaxis healed completely within six months post-parathyroidectomy.
• This suggests parathyroidectomy may be an effective therapeutic option for calciphylaxis in select patients with concurrent hyperparathyroidism.
