Treatment of Calciphylaxis: A Case for Oral Sodium Thiosulfate.

Treatment of Calciphylaxis: A Case for Oral Sodium Thiosulfate. Adv Perit Dial. 2016;32:51-55 Authors: Shetty A, Klein J Abstract Calciphylaxis is a major cause of morbidity and mortality in end-stage renal disease (ESRD). Intravenous sodium thiosulfate (STS) is the mainstay of therapy for calciphylaxis. In peritoneal dialysis (PD) patients with calciphylaxis, intravenous STS poses logistic and financial challenges. Even though pharmacokinetic studies show poor bioavailability of oral STS, we report successful use of oral STS in 2 PD patients with calciphylaxis.A 55-year-old Latina American woman with diabetes was initiated on PD after access failure and chronic hypotension. She developed painful ischemic lesions in the left middle finger and left big toe 4 months later. The ischemia in the left hand progressed, requiring amputation of two fingers. She later developed extensive painful calcific areas in the abdominal wall. She was initially started on oral STS 1500 mg twice daily that was subsequently increased to 3750 mg daily, which resulted in substantial pain relief and a decrease in the size of the calcific plaques.Another diabetic patient with ESRD who was on PD presented with a painful ischemic finger for 2 years. He was treated with oral STS 1500 mg twice daily, resulting in prompt pain relief.Oral STS can be an effective treatment for calciphylaxis. PMID: 28988590 [PubMed]
