| Outline of Final Research Achievements |
To evaluate the role of calci-protein particle (CPP) as a pathogen in chronic kidney disease, we measured serum concentration of CPP and T50, the latter being the time for CPP to transform in vitro to more cytotoxic form secondary CPP. Serum concentration of CPP was not increased in hemodialysis patients than healthy volunteers, and no correlation was found between CPP level and T50. In a cohort of hemodialysis patients, a shorter T50 predicted a higher risk of mortality, but CPP did not. These results support the hypothesis that CPP, following transformation in vivo, could play a pathological role in chronic kidney disease.
