description | Introduction
In the advanced stage of chronic kidney disease (CKD), electrolytes, fluids, and metabolic wastes including various uremic toxins, accumulate at high concentrations in the patients’ blood. Hemodialysis (HD) is the conventional procedure used worldwide to remove metabolic wastes. The creatinine and urea levels have been routinely monitored to estimate kidney function and effectiveness of the HD process. This study, first from in Indian perspective, aimed at the identification and quantification of major uremic toxins in CKD patients on maintenance HD (PRE-HD), and compared with the healthy controls (HC) as well as after HD (POST-HD).
Objectives
The study mainly focused on the identification of major uremic toxins in Indian perspective and the quantitative analysis of indoxyl sulfate and p-cresol sulfate (routinely targeted uremic toxins), and phenyl sulfate, catechol sulfate, and guaiacol sulfate (targeted for the first time), apart from creatinine and urea in PRE-HD, POST-HD, and HC groups.
Methods
Blood samples were collected from 90 HD patients (both PRE-HD and POST-HD), and 74 HCs. The plasma samples were subjected to direct ESI-HRMS and LC/HRMS for untargeted metabolomics and LC-MS/MS for quantitative analysis.
Results
Various known uremic toxins, and a few new and unknown peaks were detected in PRE-HD patients. The p-cresol sulfate and indoxyl sulfate were dominant in PRE-HD, the concentrations of phenyl sulfate, catechol sulfate, and guaiacol sulfate were about 50% of that of indoxyl sulfate. Statistical evaluation on the levels of targeted uremic toxins in PRE-HD, POST-HD, and HC groups showed a significant difference among the three groups. The dialytic clearance of indoxyl sulfate and p-cresol sulfate was found to be |

Conclusion
LC-MS/MS method was developed and validated to evaluate five major uremic toxins in CKD patients on HD. The levels of the targeted uremic toxins could be used to assess kidney function and the effectiveness of HD.</description><identifier>ISSN: 1573-3890</identifier><identifier>ISSN: 1573-3882</identifier><identifier>EISSN: 1573-3890</identifier><identifier>DOI: 10.1007/s11306-023-01978-z</identifier><identifier>PMID: 36826619</identifier><language>eng</language><publisher>New York: Springer US</publisher><subject>Biochemistry ; Biomedical and Life Sciences ; Biomedicine ; Catechol ; Cell Biology ; Chromatography, Liquid ; Creatinine ; Cresol ; Developmental Biology ; Guaiacol ; Hemodialysis ; Humans ; Indican - metabolism ; Kidney diseases ; Life Sciences ; Metabolism ; Metabolomics ; Molecular Medicine ; Original Article ; p-Cresol ; Quantitative analysis ; Renal Dialysis ; Renal Insufficiency, Chronic - metabolism ; Sulfates ; Tandem Mass Spectrometry ; Urea ; Uremic Toxins</subject><ispartof>Metabolomics, 2023-02, Vol.19 (3), p.14-14, Article 14</ispartof><rights>The Author(s), under exclusive licence to Springer Science+Business Media, LLC, part of Springer Nature 2023.
