Pro-A-type natriuretic peptide and pro-adrenomedullin predict progression of chronic kidney disease: the MMKD Study


Dieplinger, B; Mueller, T; Kollerits, B; Struck, J; Ritz, E; von Eckardstein, A; Haltmayer, M; Kronenberg, F (2009). Pro-A-type natriuretic peptide and pro-adrenomedullin predict progression of chronic kidney disease: the MMKD Study. Kidney International, 75(4):408-414.

Abstract

A-type natriuretic peptide (ANP) and adrenomedullin (ADM) are potent hypotensive, diuretic, and natriuretic peptides involved in maintaining cardiovascular and renal homeostasis. We conducted a prospective 7-year study of 177 nondiabetic patients with primary chronic kidney disease to see if ANP and ADM plasma concentrations predict the progression of their disease, using novel sandwich immunoassays covering the midregional epitopes of the stable prohormones (MRproANP and MR-proADM). Progression of chronic kidney disease was defined as doubling of baseline serum creatinine and/or terminal renal failure, which occurred in 65 patients. Analysis of the receiver operating characteristic curve for the prediction of renal endpoints showed similar areas under the curve for the glomerular filtration rate (GFR) (0.838), MR-proANP (0.810), and MRproADM (0.876), respectively, as did the Kaplan-Meier curve analyses of the patients stratified according to the median of the respective markers. In separate multiple Cox-proportional hazard regression analyses, increased plasma concentrations of both peptides were each strongly predictive of the progression of chronic kidney disease after adjustments for age, gender, GFR, proteinuria and amino-terminal pro-B-type natriuretic peptide. Our study suggests that MR-proANP and MR-proADM are useful new markers of progression of primary nondiabetic chronic kidney disease.

TrendTerms

TrendTerms displays relevant terms of the abstract of this publication and related documents on a map. The terms and their relations were extracted from ZORA using word statistics. Their timelines are taken from ZORA as well. The bubble size of a term is proportional to the number of documents where the term occurs. Red, orange, yellow and green colors are used for terms that occur in the current document; red indicates high interlinkedness of a term with other terms, orange, yellow and green decreasing interlinkedness. Blue is used for terms that have a relation with the terms in this document, but occur in other documents.
You can navigate and zoom the map. Mouse-hovering a term displays its timeline, clicking it yields the associated documents.
