Modifications of endocrine-metabolic abnormalities of uremia by continuous ambulatory peritoneal dialysis
1Department of Medicine, Uniformed Services University of the Health Sciences, Bethesda, Md.
Abstract:
The endocrine-metabolic disturbances of renal failure have numerous underlying mechanisms. These include abnormal secretion, transport and target cell binding and impaired synthesis or elimination by the diseased kidney. Neither hemodialysis nor CAPD removes large quantities of retained hormones. By correcting certain metabolic, fluid and electrolyte abnormalities, however, dialysis may improve some endocrine disturbances. Other factors such as malnutrition, glucose loading, protein loss, trace metal accumulation and drug ingestion may influence the endocrine-metabolic aspects of renal failure treated by dialysis. Hormonal stimulation and action can be adversely affected by hyperendorphinism due to retained opioids which may be removed by dialysis [88]. Possibly due to the more permeable membrane or because of continuous therapy, peritoneal dialysis seems to have a more salutary effect on hormonal regulation of salt and water balance, of erythrocyte mass and of female reproductive function than hemodialysis does.
Insights
Renal failure causes endocrine-metabolic issues. Dialysis can improve some hormonal imbalances by correcting metabolic problems, with peritoneal dialysis showing benefits for hormonal regulation.
Area of Science:
- Nephrology
- Endocrinology
- Metabolic Science
Background:
- Renal failure leads to complex endocrine-metabolic disturbances.
- These arise from impaired hormone secretion, transport, synthesis, and elimination by diseased kidneys.
- Factors like malnutrition and drug use also impact endocrine function in renal failure.
Purpose of the Study:
- To explore the endocrine-metabolic disturbances in renal failure.
- To assess the impact of dialysis (hemodialysis and CAPD) on these disturbances.
- To compare the effects of peritoneal dialysis versus hemodialysis on hormonal regulation.
Main Methods:
- Review of mechanisms underlying endocrine-metabolic disturbances in renal failure.
- Analysis of hormone removal by hemodialysis (HD) and continuous ambulatory peritoneal dialysis (CAPD).
- Evaluation of how dialysis corrects metabolic abnormalities and influences hormonal actions.
Main Results:
- Neither HD nor CAPD effectively removes large quantities of retained hormones.
- Dialysis can improve endocrine disturbances by correcting metabolic, fluid, and electrolyte imbalances.
- Peritoneal dialysis may offer superior hormonal regulation for salt/water balance, erythrocyte mass, and female reproductive function compared to hemodialysis.
Conclusions:
- Dialysis offers partial improvement for endocrine-metabolic disturbances in renal failure.
- Peritoneal dialysis demonstrates a potentially more beneficial effect on specific hormonal regulations than hemodialysis.
- Further research into optimizing dialysis strategies for endocrine health is warranted.
