The associations of calciphylaxis with thrombophilia and thrombosis are well known. 6,7 COVID-19 presumably served as a precipitant for her prior thromboembolism and calciphylaxis. Her workup to date has been unrevealing though. Sodium thiosulfate remains the first-line treatment for uremic calciphylaxis. 3 Based on our patient's response to sodium thiosulfate, we recommend that its use be considered as firstline therapy for COVID-19 patients with calciphylaxis.
