ObjectivesTo examine whether improved plasma cysteine (tCys) clearance in patients receiving home nocturnal hemodialysis (HNHD) (7 hrs/session, 6 nights/wk), influenced their erythrocyte (RBC) glutathione (GSH) concentration and riboflavin status, compared to patients on standard hemodialysis (SHD) (4 hrs/session, 3 d/wk).MethodsWe measured RBC GSH concentration by liquid chromatography tandem mass spectrometry & riboflavin status by RBC GSH reductase activity coefficient (EGRAC) in 15 HNHD, 15 SHD & 15 healthy controls (HC) participants. Estimated dietary protein intake (PRO), and plasma tCys, homocysteine (tHcy), C‐reactive protein (CRP) and vitamin C were also determined.Median (25th, 75th percentile)ConclusionRBC GSH and riboflavin status may be unaffected by hemodialysis modality in well nourished HD patients.

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
