Creatinine remains the standard for laboratory diagnosis of AKI. Efforts to prevent nephrotoxicity have been harmed by the delay in the diagnosis of AKI criteria by using only the creatinine as a marker, therefore there is great interest in identifying early reliable biomarkers. Moreover, early treatment of ARF can be correlated with a better prognosis and identification of biomarkers for early diagnosis would improve the efficacy of a therapeutic strategy. Thus, it becomes imperative to find biomarkers that can stratify correctly the extent of renal damage that each patient has suffered and the risk of developing chronic kidney disease (CKD). Here, we review the main features of emerging biomarkers in nephrology.

Reincidencia de eventos coronarios: disfunción endotelial como mediadora Resumen Existe evidencia de que luego de un evento coronario (EC) sucede una respuesta inflamatoria que acrecienta la disfunción endotelial y que puede motivar un nuevo EC a corto plazo. Se describe reincidencia de fenómenos isquémicos en el vaso comprometido inicialmente y en otros territorios vasculares. Las modificaciones fisiopatológicas potencialmente terapéuticas no tienen un impacto clínico aplicable en la práctica cardiológica habitual.
