Calciprotein particles (CPP) are a novel marker of mineral stress. High levels of CPP are found in patients with calciphylaxis, a condition associated with marked vascular calcification and a poor prognosis. We report substantial reductions in CPP levels in a dialysis patient having combined haemodialysis (HD) and plasma exchange (PEx) prior to an ABO-incompatible kidney transplant. We also report the effects of the same treatments combined with sodium thiosulphate (STS) in a patient newly diagnosed with calciphylaxis. Combining HD with intra-dialytic STS and PEx we achieved a significant reduction in CCP with the least rebound between treatment sessions. After 6 weeks of treatment, the CPP reduction was paralleled by clinical improvement. Measurement of CPP may be an attractive marker for monitoring the effectiveness of calciphylaxis therapy
