Serum albumin and creatinine rose by 12 to 13% during the first half year of hemodialysis in a stable cohort. The slope of serum albumin versus time predicted survival, but it was not as predictive as the absolute albumin concentration. The pattern of correlations of baseline urinary protein and creatinine excretion with the respective monthly serum values of albumin and creatinine and their slopes is consistent with the hypothesis that as residual renal function declines, progressive retention of protein and creatinine contributes to the respective rises in serum albumin and creatinine.
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.
