Dialysis encephalopathy.

A C Alfrey

    Clinical Nephrology
    |January 1, 1985

    Summary

    Aluminum accumulation causes dialysis encephalopathy, a fatal neurological condition. Oral aluminum-containing phosphate binders are a significant source, necessitating careful use and alternative phosphorus control methods.

    Area of Science:

    • Nephrology
    • Neurology
    • Toxicology

    Background:

    • Dialysis encephalopathy is a progressive neurological disorder with a high mortality rate.
    • While historically linked to hemodialysis, it now affects non-dialyzed and peritoneal dialysis patients.
    • Biochemical and epidemiological evidence strongly implicates aluminum in the disease's development.

    Purpose of the Study:

    • To investigate the sources of aluminum loading in patients with dialysis encephalopathy.
    • To highlight the role of orally administered phosphate-binding agents in aluminum toxicity.
    • To recommend strategies for managing phosphorus levels and preventing aluminum accumulation.

    Main Methods:

    • Review of biochemical and epidemiological data.
    • Analysis of aluminum sources in uremic patients.
    • Clinical observation of dialysis encephalopathy progression.

    Main Results:

    • Aluminum is a key factor in dialysis encephalopathy pathogenesis.
    • Aluminum-contaminated dialysate was an initial concern.
    • Orally administered aluminum-containing phosphate binders are a significant and increasingly recognized source of aluminum loading.

    Conclusions:

    • Aluminum toxicity is a critical concern in managing uremic patients.
    • Minimize the use of aluminum-containing phosphate binders.
    • Explore and implement alternative phosphorus control strategies to prevent aluminum accumulation.
