Big endothelin-1 in cats with CKD : preliminary evaluation

In human medicine the concentration of serum endothelin-1 (ET-1)increases in hypertension and CKD. Also urinary ET-1 correlates withthe severity of renal disease and the magnitude of proteinuria. In dogs,increased concentration of ET-1, evaluated indirectly by the precursorBig Endothelin-1 (big-ET1), seems to be associated with the severityof CKD and hypertension.The aim of this study was to gain information about serum and urinarylevels of big-ET1 in cats with CKD, with and without hypertensionand proteinuria.
