Immunoreactive epidermal growth factor in serum, plasma, platelets, and urine in patients on chronic dialysis.

Author information

City of Hope National Medical Center, Duarte, Calif.


In 25 patients with chronic renal failure undergoing hemodialysis the level of epidermal growth factor (EGF) was significantly increased in plasma (61 +/- 10 vs. 36 +/- 12 pM in 23 aged-matched controls; p less than 0.0001) and serum (189 +/- 51 vs. 138 +/- 69 pM, p less than 0.006) and slightly increased in platelets (391 +/- 134 vs. 308 +/- 87 aM/10(6) platelets in controls; p less than 0.0582). In those 15 patients who produced urine, EGF was absent or close to the low limit of the sensitivity of the method (17 pM). Thus, kidneys are not delivering EGF to blood but their role in EGF removal is possible. Urinary EGF virtually disappears in severe chronic renal failure.
