| Outline of Final Research Achievements |
For development of order-made diagnostis for chronic kidney disease and hemodailysis (HD) patients, we applied omocs-integrated analysis of plasma and dialysate from HD patients. To investigate metabolic responses to HD, we have determined levels of metabolites by nuclear magnetic resonance (1H NMR) spectroscopy of dialysate during HD. Unlike the response of creatinine, lactate, pyruvate and alanine exhibited increments at the middle time of HD. The time-course of changes in these metabolites was unique to each patient.
Muscle cramp is a common complications of HD. We defined score of the cramps and measured the effects of oral administration of biotin to cramps. We measured plasma biotin levels of the patients before prescribed biotin by ELISA methods, and found they were dependent on the efficacies of prescribed biotin. The fact of fenome (cramp scores) and metabolome (biotin levels) were correlated may provide information to the order-made diagnosis of HD patients.
