Hormonal changes in hemodialysis.

Abstract

When chronic renal failure becomes advanced, the serum or tissue levels and/or the functions of most hormones are altered because of several interplaying mechanisms involving synthesis, transport, accumulation of inhibitors, abnormality of target organ responsiveness, and impaired renal clearance. As regular dialysis treatment is performed, most of these uremic hormone abnormalities are not reversed, and some of them may even get worse. The main endocrine derangements can be grouped as sexual hormone dysfunction, thyroid abnormalities, growth retardation, hormone-related disorders of metabolism, derangements of pressor substances, gastrointestinal peptide abnormalities, renal osteodystrophy, and anemia. The endocrine abnormalities play a major role as for the clinical and metabolic rehabilitation of dialysis patients.
