Author Reply to Comment on “Assessment of Plasma Oxalate Concentration in Patients With CKD” by Oka et?al.

摘要

To the Editor: In the recent article by Pfau et al., 1 “Assessment of Plasma Oxalate Concentration in Pa- tients With CKD,” they reported a new simple pro- cedure for evaluating plasma oxalate (POx) concentration that enabled the investigation of a large cohort of patients with chronic kidney disease (CKD). 1 They measured POx in 1826 patients with CKD and found stable results; furthermore, they reaffirmed a negative correlation between the estimated glomerular filtration rate and POx.
