  • Patent number: 11181523
    Abstract: The invention is an ex vivo method for early detection of acute kidney injury in critical patients, which includes the measurements of fibroblast growth factor 23 (FGF23), klotho (KL) and erythropoietin (EPO) as biomarkers. These measurements are obtained from a venous blood sample or urine, and allow the determination of the following indicators: 1=([FGF23]p×[EPO]p); 2=([FGF23]p/[Klotho]p); 3=([EPO]p)/[Klotho]p); 4=([FGF23]p×[EPO]p)/[Klotho]p); where [X]p is defined as the plasma level of a specific molecule (X) which includes fibroblast growth factor 23 (FGF23), klotho (KL) or erythropoietin (EPO). If the value of the indicator 1, 2, 3, 4 or two or more thereof, is equal or higher than a cut-off point (10 U), the indicator and/or indicators allow the identification of patients with high risk of developing AKI, with a high sensitivity/specificity.
    Type: Grant

  • Patent number: 9511120
    Abstract: The present invention is related to the use of the angiotensin-(1-9) peptide or peptides derived therefrom, which are biological or chemical analogs, for preparing medicaments useful for preventing, reverting, inhibiting and/or reducing hypertension and/or inducing vasodilation. Furthermore, this invention also comprises a vector overexpressing the homologous angiotensin-II converting enzyme (ACE2) for elevating the concentration in the blood and/or tissues of the angiotensin-(1-9) peptide. This vector may be adenovirus, retrovirus, lentivirus or adeno-associated virus containing the gene encoding for ACE2.
