Chronic renal failure is associated with an abnormal growth hormone/in
sulin-like growth factor-1 axis. In addition, nutritional status stron
gly regulates this axis. Because these hormones are involved in growth
in children and maintenance of a normal body composition in adults, e
xperimental and clinical studies have tested the metabolic effects of
these recombinant growth factors. Various conditions in which these gr
owth factors have been administered have been reported, such as the re
covery of acute renal failure, protein metabolism in chronic renal fai
lure, growth improvement in uremic children, the increase in renal fun
ction in nondialyzed uremic patients, and the potential treatment of m
alnutrition in adult maintenance dialysis patients.
