What Researchers Did
Researchers reported a case of a 69-year-old hemodialysis patient with Graves disease who developed severe bilateral lower limb calciphylaxis (skin and vessel calcification with ulcers), treated with a multidisciplinary protocol including HBOT, skin grafting, and medical therapy.
What They Found
The lesions healed completely with the multidisciplinary protocol, which included daily hemodialysis, sodium thiosulfate, denosumab, HBOT, and skin autograft. The authors note this was the first reported case of calciphylaxis secondary to hyperthyroidism in a dialysis patient.
What This Means for Canadian Patients
Calciphylaxis is a rare but potentially fatal condition that can occur in Canadian dialysis patients. HBOT appears to play a useful role as part of a multidisciplinary treatment package, particularly for wound healing in these patients who are extremely difficult to manage with conventional approaches.
Canadian Relevance
No direct Canadian connection identified.
Study Limitations
This is a single case report of a rare presentation; no controlled evidence exists for HBOT in calciphylaxis, and outcomes are confounded by multiple simultaneous interventions.
