Mohamed Magdy Badr: Calciphylaxis – The Silent Killer in Kidney Failure

”Calciphylaxis: The Silent Killer in Kidney Failure

A rare but devastating vascular-cutaneous emergency that every clinician must recognize early.

What Is Calciphylaxis?

Calciphylaxis is a life-threatening syndrome caused by progressive calcification, thrombosis, and occlusion of small dermal and subcutaneous arterioles.
The result? Severe ischemia → deep necrosis → non-healing ulcers with extremely high mortality.

Who Is at Risk?

  • Most commonly seen in patients with:
  • End-Stage Renal Disease (ESRD) on dialysis
  • Disturbed calcium–phosphate balance
  • High PTH (secondary hyperparathyroidism)
  • Diabetes, obesity, liver disease
  • Warfarin therapy
  • Low serum albumin

How It Presents Clinically

Calciphylaxis lesions typically evolve through:

  1. Painful violaceous livedo reticularis
  2. Indurated plaques or nodules
  3. Ulceration with black eschar (necrosis)
  4. Risk of rapid infection, sepsis, and limb loss

Key red flag: Pain is often out of proportion to the visible lesion.

Common sites: thighs, abdomen, buttocks, legs—areas rich in adipose tissue.

Diagnosis

  • Primarily clinical, supported by:
  • Elevated Ca × PO₄ product
  • Increased PTH
  • Imaging showing soft-tissue calcification
  • Biopsy only when necessary (may worsen the wound)

Management: Multidisciplinary and Urgent

Successful management requires rapid, coordinated intervention:

1. Correct Mineral Imbalance

  • Phosphate binders
  • Aggressive control of Ca/PO₄
  • Cinacalcet for PTH regulation

2. Discontinue Warfarin

  • One of the most evidence-based steps.

3. Sodium Thiosulfate

  • IV infusion after hemodialysis—now a cornerstone therapy.

4. Optimal Wound Care

  • Gentle debridement
  • Infection prevention
  • Moisture balance
  • Pain management (often severe)

5. Consider Parathyroidectomy

  • For refractory secondary hyperparathyroidism.

Prognosis

  • Mortality remains 50–80%, mainly due to sepsis.
  • Early detection and aggressive treatment dramatically improve survival.

Take-Home Message

  • Any dialysis patient with severe, disproportionate pain, violaceous patches, or evolving necrotic ulcers should raise immediate suspicion for calciphylaxis.
  • Early recognition = better outcomes.
  • Delayed recognition = catastrophic consequences.”
