Patents by Inventor John A. Kellum

John A. Kellum has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Publication number: 20240118289
    Abstract: This invention is related to the field of the prevention and treatment of kidney disease. The treatment of kidney disease may be tailored depending upon the need for, or expectation of, long-term dialysis. For example, prediction of long-term dialysis treatment can be determined by monitoring urine biomarkers related to the development of chronic kidney disease. For example, a normalized time course of approximately fourteen Days measuring hyaluronic acid, death receptor 5, and/or transforming growth factor ?1 can be used to establish the risk of recovery versus non-recovery in patient's having suffered an acute kidney injury.

  • Patent number: 11747342
    Abstract: A proteomic expression platform to identify age-related sepsis risk is disclosed using patients with an intra-abdominal infection. A semi-quantitative plasma proteomics workflow was applied which incorporated tandem immuno affinity depletion, iTRAQ labeling, strong cation exchange fractionation, and nanoflow-liquid chromatography coupled to high resolution mass spectrometry. A protein profile was determined that exhibit statistically significant differences in expression levels amongst patients with severe sepsis as a function of age. Representative pathways that are differentially-expressed include, but are not limited to, acute phase response, coagulation signaling, atherosclerosis signaling, lipid metabolism, and production of nitric oxide/reactive oxygen species.

  • Publication number: 20220143133
    Abstract: It is an object of the present invention to provide methods and compositions for protection of subjects from acute kidney injury by treating the subject with compounds that modulate the cell cycle. Modulating the cell cycle can comprise inducing G0/G1 cell cycle arrest, and/or inducing cell cycle progression. As demonstrated below, even a single administration of a compound which induces G0/G1 cell cycle arrest can protect subjects from AKI, and may be used prophylactically in advance of, or as a treatment following, various treatments or conditions that are known to be injurious to the kidney, followed optionally by release of the arrest. Once AKI is established, cell cycle progression can be induced to increase replacement of lost and damaged cells.

  • Publication number: 20200284805
    Abstract: Disclosed herein are methods of identifying biomarkers (such as genes (e.g., RNA or mRNA), proteins, and/or small molecules) that can be used to predict organ or tissue function or dysfunction. In some embodiments, the methods include ex vivo perfusion of the organ or tissue, collection of samples from the organ or tissue (for example, perfusate, fluids produced by the organ (such as bile or urine), or tissue biopsies) and measuring the level of one or more biomarkers in the sample. It is also disclosed herein that an analysis of biomarkers (such as genes (e.g., RNA or mRNA), proteins, and/or small molecules) present in a biological sample from an organ, tissue, or subject can be used to identify whether the organ, tissue, or subject is at risk for (or has) organ dysfunction or organ failure.

  • Patent number: 10533989
    Abstract: The present invention describes a global metabolomic profile of patients with community acquired pneumonia (CAP) and sepsis. The metabolomic profile of endogenous small molecules blood was determined using mass-spectrometry. The global metabolomic profile in plasma demonstrated broad differences between CAP and sepsis patients when comparing those who do and do not survive at 90 days. Increases in specific metabolite biomarkers displayed on a heat map provide early diagnosis of these medical conditions to allow for early intervention and aggressive treatment.
