On the day of inclusion, median (interquartile range) fractional sodium excretion, fractional urea nitrogen excretion, blood urea nitrogen-to-creatinine ratio, and urine osmolality were 4.
In the present study a decreased fractional sodium excretion followed by an enhanced fractional post-proximal sodium reabsorption between the seventh and fourteenth days after CHE administration were observed, despite an increased filtered-sodium load.
