title: Efficacy of sodium thiosulfate for the treatment for calciphylaxis.
abstract: OBJECTIVE
  Calciphylaxis is a rare condition with dismal prognosis that affects patients with ESRD. Sodium thiosulfate (STS) may play a therapeutic role but its proposed efficacy is based on case reports and thus subject to publication bias.
  
  
  METHODS
  We identified all patients who received STS for any indication over a 5-year period through pharmacy records of 4 hospitals, retrospectively reviewing medical records for risk factors, laboratory values, the response of skin lesions to STS, and mortality.
  
  
  RESULTS
  14 patients received STS for calciphylaxis over 5 years. Following STS administration, pain decreased in 71% of patients, and 70% had an improvement in their lesions. Those who did not improve or stabilize their skin lesions tended to have more advanced skin lesions, were on renal replacement therapy longer, were more obese and received less total dose of STS. However, despite STS, there was a 71% mortality rate, with 50% of subjects dying within 6 months.
  
  
  CONCLUSIONS
  We conclude in this study of all subjects who received STS at our Institution that STS is an effective treatment for the pain and skin lesions of calciphylaxis if given in the early stages of disease and for a consistent period of time. However, there is little impact on overall mortality compared to historical published cohorts.
