The fractional excretion of sodium in patients with cystic fibrosis treated with oral sodium chloride.

Cystic Fibrosis (CF) is a chronic disease associated with low sodium status. The patients are usually treated with oral sodium chloride to control the side effects of low sodium status. Therefore, the fractional excretion of sodium (FE) was assessed in patients with cystic fibrosis (CF) treated with oral sodium chloride (NaCl).
