  • Publication number: 20140228296
    Abstract: The present invention relates to the discovery that an increased fraction of albumin is carbamylated in patients suffering from kidney disease (e.g., end-stage renal disease) and that the fraction of carbamylated albumin is also correlated with increased disease severity, particularly risk of mortality. The present invention also relates to the discovery that free amino acids can reduce carbamylation of albumin. Based on these discoveries the present invention provides diagnostic and prognostic methods for patients suffering from, or suspected of suffering from kidney disease. The invention also provides methods for treating kidney disease by administration of a compound or composition that reduced protein carbamylation, such as free amino acids or dipeptides.

  • Publication number: 20130252821
    Abstract: Disclosed herein are methods for treating a vascular leak disorder, hypotension, or a procoagulant state using angiopoietin-2 (Ang-2) antagonist compounds. Also disclosed are methods for treating a vascular leak disorder associated with high dose IL-2 therapy using angiopoietin-2 antagonist compounds. Methods for diagnosing and monitoring vascular leak disorders, hypotension, or a procoagulant state that include the measurement of Ang-2 polypeptide or nucleic acid levels are also disclosed.

  • Publication number: 20120020974
    Abstract: The methods described herein can be used to identify ex ante which hemodialysis patients are likely to develop EPO resistance and therefore will require additional rHu EPO, and to provide treatments that can reduce the need for additional rHu EPO. In addition, the methods can be used to predict which subjects have a higher risk of mortality, to identify high-risk patients who can then be monitored more closely or treated more aggressively. Also provided are kits for carrying out the described methods.
