| Research Abstract |
We measured plasma biotin concentrations in hemodialysis patients by the ELISA method. The biotin concentrations in the patients were higher than that in the normal subjects. The ELISA detects all the molecules with biotin-backbone structures. The results indicated that renal disease patients without uric excretion accumulate biotin and biotin-metabolites in the blood. It was suggested the metabolites have no activity as vitamine, and disturb intact biotin. Chronic disease patients are affected seriously by the accumulated metabolites.
For identification and quantification of biotin and the metabolites, we developed the LC/MS system.
By NMR measurement of the plasma and spent dialysate samples from the patients, we study metabolic features special to chronic disease patients for the novel diagnosis.
