Once established, it results in a progressive accumulation of a myriad of uraemic toxins. Peritoneal dialysis (PD) uses the body\u2019s peritoneal membrane to remove these toxins across a semipermeable membrane to restore and maintain homeostasis. Traditionally, dialysis adequacy has been measured through clearance of urea and creatinine. However, numerous studies have shown marginal links comparing the clearance of urea and creatinine with clinical outcomes reflected in the recent changes to the ISPD guidelines on dialysis adequacy. Instead, attention has focused on protein-bound uraemic toxins (PBTs). Produced by gut bacteria, these molecules are highly protein-bound and poorly removed by either dialysis or absorptive agents. Elevated concentrations of molecules such as p-cresyl sulfate and indoxyl sulfate have been associated with abnormal cellular function and poor patient outcomes. However, widespread use of these measures to determine dialysis adequacy has been limited by the need for specialized techniques required for measurement. Altering the gut microbiome to reduce generation of PBTs through increased dietary fiber might be an alternate approach to better patient outcomes, with some initial positive reports. This report explores advantages and limitations of measuring uraemic toxins in PD, now and in the foreseeable future.<\/jats:p>","DOI":"10.3390\/jcm14041395","type":"journal-article","created":{"date-parts":[[2025,2,19]],"date-time":"2025-02-19T09:36:22Z","timestamp":1739957782000},"page":"1395","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":4,"title":["Benefits and Pitfalls of Uraemic Toxin Measurement in Peritoneal Dialysis"],"prefix":"10.3390","volume":"14","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-2807-2420","authenticated-orcid":false,"given":"Aruni","family":"Malaweera","sequence":"first","affiliation":[{"name":"Department of Renal Medicine, Eastern Health, 5, Arnold Street, Box Hill, Melbourne, VIC 3128, Australia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4883-420X","authenticated-orcid":false,"given":"Louis","family":"Huang","sequence":"additional","affiliation":[{"name":"Department of Renal Medicine, Eastern Health, 5, Arnold Street, Box Hill, Melbourne, VIC 3128, Australia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3204-6444","authenticated-orcid":false,"given":"Lawrence","family":"McMahon","sequence":"additional","affiliation":[{"name":"Department of Renal Medicine, Eastern Health, 5, Arnold Street, Box Hill, Melbourne, VIC 3128, Australia"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2025,2,19]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"2597","DOI":"10.1093\/ndt\/12.12.2597","article-title":"Incidence and risk factors of atherosclerotic cardiovascular accidents in predialysis chronic renal failure patients: A prospective study","volume":"12","author":"Jungers","year":"1997","journal-title":"Nephrol.
