Epoetin dose requirement is an independent predictor of total mortality in hemodialysis patients after adjustment for hematocrit. Poor responders who continue to have low hematocrit values despite the administration of high epoetin doses may not necessarily benefit from more epoetin, but perhaps should be considered for other adjunctive therapies. In contrast to conventional wisdom, this study suggests that epoetin dosing requirements could provide important prognostic information beyond that predicted by hematocrit alone.
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.
