Elimination of hormones through hemofiltration

Area of Science:

• Nephrology
• Endocrinology
• Biochemistry

Background:

• Uremia, a condition of kidney failure, affects hormone levels.
• Hormone replacement therapy is common in uremic patients.
• The impact of hemofiltration on hormone concentrations requires further investigation.

Purpose of the Study:

• To determine the effect of intermittent hemofiltration on plasma and ultrafiltrate concentrations of key hormones.
• To assess whether hemofiltration leads to hormone deficiency in uremic patients.

Main Methods:

• Plasma and ultrafiltrate samples were collected from five uremic patients undergoing intermittent hemofiltration.
• Concentrations of testosterone, cortisone, gastrin, gastric inhibitory polypeptide (GIP), somatomedin B, insulin, human growth hormone (HGH), and thyroid-stimulating hormone (TSH) were measured.

Main Results:

• Significant loss of gastrin, GIP, somatomedin B, and insulin was observed during hemofiltration, yet plasma levels remained unchanged.
• Cortisone, HGH, and TSH were undetectable in the ultrafiltrate.
• Hemofiltration did not result in a decrease in measured plasma hormone concentrations.

Conclusions:

• Intermittent hemofiltration does not induce a hormone deficiency syndrome in uremic patients.
• The removal of biologically active hormone degradation products by hemofiltration may offer therapeutic advantages.
