Calciphylaxis is a rare and serious disorder characterized by vascular calcification and occlusion of the microvessels in the dermis, subcutaneous adipose tissue, visceral organs, and musculature. Studies have suggested that the major risk factors for developing calciphylaxis are chronic kidney disease and secondary hyperparathyroidism. Its diagnosis is clinical, and the treatment includes a multidisciplinary approach, although there are no clinical protocols based on randomized clinical trials. Therefore, the management and treatment are informed by specialist opinion. Sodium thiosulfate is frequently utilized for its vasodilatory and antioxidant properties, as well as its ability to chelate calcium. However, there are no guidelines regarding the duration of its use. The present report describes a chronic kidney disease patient on hemodialysis with calciphylaxis, who underwent sodium thiosulfate treatment for 2 years associated with debridement and reconstructive plastic surgery with a good response and control of the disease.

Calciphylaxis is a rare and potentially fatal condition involving chronic, nonhealing wounds caused by microvascular calcification. There is currently no approved treatment for calciphylaxis, contributing to its devastating impacts on quality of life. In this case series, the authors highlight instances of potentially misdiagnosed calciphylaxis in a cohort of patients and emphasize the importance of accurate diagnosis through multidisciplinary management approaches.

Uremic pruritus (UP) is a debilitating condition frequently associated with chronic kidney disease, severely impairing patients' quality of life and contributing to increased mortality. Recent studies have suggested that intravenous sodium thiosulfate (STS) may offer therapeutic relief for pruritus in patients undergoing hemodialysis. To assess its effectiveness, we conducted a systematic review and meta-analysis to explore the potential of intravenous STS in managing UP.

Cisplatin is a common and highly effective chemotherapeutic agent whose nephrotoxic side effect is well-characterized. Sodium thiosulfate (STS), an FDA-approved hydrogen sulfide (HS) donor drug, is emerging as a chemoprotective agent against cisplatin-induced nephrotoxicity (CIN). In this study, we investigated the chemoprotective mechanism of STS in a rat model of CIN.

Mercury contamination of the environment is extremely hazardous to human health because of its significant toxicity, especially in water. Biomass-derived fluorophores such as carbon dots (CDs) have emerged as eco-friendly and cost-effective alternative sensors that provide comparable efficacy while mitigating the environmental and economic drawbacks of conventional methods. In this work, we report the fabrication of a selective fluorescence-enhancing sensor based on sulfur-doped carbon dots (SCDs) using waste bamboo-derived cellulose and sodium thiosulfate as the soft base dopant, which actively complexes with mercury ions for detection.
