ABSTRACT
The insulin-like growth factor-I(IGF-I) is a hormone that has growth stimulation and metabolic effects. Insulin-like growth factor binding proteins (IGFBPs) were known to be the most important factors that affect bioavailability of IGF. Thereby, the changes of IGFBPs may affect the bioavailability of IGF-I. Because growth hormone/IGF system may be affected by dialysis therapy, the changes of GH, IGF-1, IGFBPs levels after dialysis therapy can affect the bioavailability of IGF. To evaluate the changes of serum levels of IGF-I and IGFBP-3 after long-term dialysis therapy, we measured the serum IGF-I and IGFBP-3 levels in the patients on hemodialysis and on peritoneal dialysis. Eight patients undergoing peritoneal dialysis, 10 patients undergoing hemodialysis, and age-matched 10 normal control patients were studied. In patients on hemodialysis, the mean serum level of IGF-I before hemodialysis was 90.6+/-9.0 nanogram/mL, and after long-term hemodialysis was 130.9+/-31.0 nanogram/milliliter. The mean serum level of IGFBP-3 before hemodialysis was 14,549+/-7,815 microgram/liter, and after long-term hemodialysis was 5,726+/-883 microgram/liter. There were no significant changes of serum IGF-I and IGFBP-3 levels after long-term hemodialysis therapy. In patients on peritoneal dialysis, the mean serum level of IGF-I before peritoneal dialysis was 169.8+/-20.5 nanogram/milliliter, and after long-term peritoneal dialysis was 242.6+/-37.6 nanogram/mL. The mean serum level of IGFBP- 3 before peritoneal dialysis was 10,272+/-885 microgram/liter, and after ling-term peritoneal dialysis was 8,604+/-1,721 microgram/liter. There were no significant changes of serum IGF-I and IGFBP-3 levels after long-term peritoneal dialysis. We found that the level of IGF-1 before hemodialysis was lower then that of normal control group and the level of IGFBP-3 before hemodialysis or peritoneal dialysis was higher then that of normal control group. Our results suggested that the blood levels of growth hormone, IGF-I and IGFBP-3 may not be significantly affected by long-term dialysis therapy.
