Sodium thiosulphate (STS) has been used as an off-label therapeutic in calciphylaxis, but there is a lack of clinical trials and studies that demonstrate its effect compared with those without STS treatment.<\/jats:p><\/jats:sec>Objective<\/jats:title>To perform a meta-analysis of the cohort studies that provided data comparing outcomes among patients with calciphylaxis treated with and without intravenous STS.<\/jats:p><\/jats:sec>Data Sources<\/jats:title>PubMed, Embase, Cochrane Library, Web of Science, and ClinicalTrials.gov were searched using relevant terms and synonyms including sodium thiosulphate<\/jats:italic> and calci*<\/jats:italic> without language restriction.<\/jats:p><\/jats:sec>Study Selection<\/jats:title>The initial search was for cohort studies published before August 31, 2021, that included adult patients diagnosed with CKD experiencing calciphylaxis and could provide a comparison between patients treated with and without intravenous STS.

No difference was observed in skin lesion improvement (12 studies with 110 patients; risk ratio, 1.23; 95% CI, 0.85-1.78) between the STS and the comparator groups. No difference was noted for the risk of death (15 studies with 158 patients; risk ratio, 0.88; 95% CI, 0.70-1.10) and overall survival using time-to-event data (3 studies with 269 participants; hazard ratio, 0.82; 95% CI, 0.57-1.18). In meta-regression, lesion improvement associated with STS negatively correlated with publication year, implying that recent studies are more likely to report a null association compared with past studies (coefficient\u2009=\u2009\u22120.14; P<\/jats:italic>\u2009=\u2009.008).<\/jats:p><\/jats:sec>Conclusions and Relevance<\/jats:title>Intravenous STS was not associated with skin lesion improvement or survival benefit in patients with CKD experiencing calciphylaxis.
