[The diagnostic critical value in DFO low dose loading test on patient with aluminum accumulation compared to each parameter of ROD].
One hundred two hemodialyzed patients were examined to determine the standard level of delta Al value which is the difference of serum Al concentrations between pre and post DFO loading test. We applied low dose of DFO 15 mg/kg in this loading test. Some significant negative correlations were found between delta Al and MCI, sigma GS/D, osteocalcin, free-Hydroxyproline (dialysate) and free-gamma-Carboxyglutamic acid (dialysate). Each correlation rate was -0.58, -0.44, -0.76, -0.57 and -0.51 respectively. In addition tendencies of correlation were found between delta Al and ALP and between delta Al and %QCT (QCT/mean QCT in patient's age x 100). And statistical significant differences were found between (0 less than delta Al less than or equal to 150 micrograms/l) group and (150 micrograms/l less than delta Al) group in each osteobiochemical parameter. These results indicate that 150 micrograms/l is the lower diagnostic standard level of delta Al in 15 mg/kg DFO loading test.
