Intestinal dialysis for conservative management of Uremia.

PURPOSE OF REVIEW

Renal replacement therapies, such as hemodialysis are invasive and impose significant financial burden as well as burden on quality of life. Conservative and 'gentler' forms of renal replacement therapy for the frail and palliative care patient is an unmet medical need.

RECENT FINDINGS

The treatment of uremia using the gut as a substitute for the kidney has been proposed but is not practiced widely because of proven lack of long-term mortality benefit coupled with complications like edema and hyperchloremia. Mounting evidence showed that endotoxins from gastrointestinal tract are a major source of chronic inflammation in chronic kidney disease (CKD). The high load of nitrogenous waste elimination through the bowel could potentially serve as an alternative modality to remove uremic wastes especially in people who opt for conservative management for end-stage renal disease with some recent studies in Iran and China showing promising benefits in uremia.

SUMMARY

In this review, we will discuss the history, recent evidence and potential of these therapies and their implications in CKD for conservative and easy management of uremia.
