[Cardiorenal syndrome: the role of new biochemical markers].

Cardiorenal syndrome is a pathophysiological heart and kidney disorder, in which acute or chronic dysfunction of one organ induces a damage in the other. It's a syndrome more and more often encountered in clinical practice and this implies the need to recognize the syndrome through biochemical markers with a good sensitivity and specificity, since its earliest stages in order to optimize therapy. In addition to widely validated biomarkers, such as BNP, pro BNP, creatinine, GFR and cystatin C, other promising molecules are available, like NGAL (neutrophil gelatinase-associated lipocalin, KIM-1 (kidney injury molecule-1), MCP-1 (monocyte chemotactic peptide), Netrin-1, interleuchin 18 and NAG (N-acetyl-β-glucosa-minidase). The role of these emerging biomarkers is still not completely clarified: hence the need of new clinical trials.
