Prolactin, growth hormone and alpha-fetoprotein in children with cystic fibrosis.

Prolactin is credited to have a role in the maintenance of electrolytic 
and water balance by the kidneys although its effect on the 
composition of sweat is unknown. We assayed prolactin, growth hormone and 
alpha-fetoprotein in the sera of 69 children with cystic fibrosis attending 
the Hospital for Sick Children. Sera from 12 children without cystic 
fibrosis were used as control. It appears that children with cystic 
fibrosis have serum levels of prolactin, GH and alpha-FP similar to 
those without this disease and that children have significantly higher levels 
of alpha-FP than women of reproductive age.
