Publication number: 20210079476Abstract: Provided herein is a method of treating low turnover renal osteodystrophy in a subject being administered an agent that reduces bone turnover comprising measuring a level of one or more miRNAs in a sample from the subject. The miRNA being measured can include miRNA-30b, miRNA-30c, miRNA-125b and miRNA-155. Administration of the agent that reduces bone turnover can be stopped if the level of the one or more miRNAs measured is lower than a level of the one or more miRNAs measured in a control subject. Administration of the agent that reduces bone turnover can be continued if the level of the one or more miRNAs measured is not lower than a level of the one or more miRNAs measured in a control subject.Type: ApplicationFiled: November 24, 2020Publication date: March 18, 2021Inventors: Thomas L. NICKOLAS, Sharon MOE, Neal X. CHEN

Publication number: 20180100866Abstract: A method of assessing the ongoing kidney status of a mammal afflicted with or at risk of developing chronic renal injury or disease, including chronic renal failure (CRF) by detecting the quantity of Neutrophil Gelatinase-Associated Lipocalin (NGAL) in urine, serum or plasma samples at discrete time periods, as well as over time. Incremental increases in NGAL levels in CRF patients over a prolonged period of time are diagnostic of worsening kidney disease. This increase in NGAL precedes and correlates with other indicators of worsening chronic renal disease or CRF, such as increased serum creatinine, increased urine protein secretion, and lower glomerular filtration rate (GFR). Proper detection of worsening (or improving, if treatment has been instituted) renal status over time, confirmed by pre- and post-treatment NGAL levels in the patient, can aid the clinical practitioner in designing and/or maintaining a proper treatment regimen to slow or stop the progression of CRF.Type: ApplicationFiled: September 10, 2014Publication date: April 12, 2018Inventors: Jonathan Matthew BARASCH, Prasad DEVARAJAN, Thomas L. NICKOLAS, Kiyoshi MORI

Publication number: 20140080155Abstract: Methods of assessing the ongoing kidney status in a subject afflicted with chronic renal failure (CRF) by detecting the quantity of Neutrophil Gelatinase-Associated Lipocalin (NGAL) in fluid samples over time. NGAL is a small secreted polypeptide that is protease resistant and consequently readily detected in the urine and serum as a result of chronic renal tubule cell injury. Incremental increases in NGAL levels in CRF patients over a prolonged period of time are diagnostic of worsening kidney disease. This increase in NGAL precedes and correlates with other indicators of worsening CRF, such as increased serum creatinine, increased urine protein secretion, and lower glomerular filtration rate (GFR). Proper detection of worsening (or improving, if treatment has been instituted) renal status over time, confirmed by pre- and post-treatment NGAL levels in the patient, can aid in designing and/or maintaining a proper treatment regimen to slow or stop the progression of CRF.Type: ApplicationFiled: November 25, 2013Publication date: March 20, 2014Inventors: Jonathan M.

Publication number: 20120214177Abstract: Methods for diagnosis of and distinguishing between, urosepsis, sepsis, and urinary tract infections (UTIs) are disclosed The diagnostic methods are based on determining the level of NGAL protein in a bodily fluid sample, such as urine sample.Type: ApplicationFiled: June 17, 2010Publication date: August 23, 2012Applicant: The Trustees of Columbia University in the City of New YorkInventors: Jonathan Barasch, Catherine Forster, Thomas L.

Patent number: 7977110Abstract: A method for distinguishing between kidney dysfunctions in a mammal, including pre-renal azotemia, an acute renal injury that may progress to acute renal failure, and chronic kidney disease, using a urinary or circulating NGAL assay result that is compared to a predetermined NGAL cutoff level, and a single serum or plasma creatinine measurement. Typically the single creatinine measurement cannot distinguish acute renal injury from chronic kidney disease or pre-renal azotemia, a single measurement of urinary NGAL, combined with the single serum or plasma creatinine measurement, has sufficient sensitivity and specificity to distinguish acute renal injury from normal function, prerenal azotemia, and chronic kidney disease and predicts poor inpatient outcomes.Type: GrantFiled: June 21, 2008Date of Patent: July 12, 2011Assignees: Children's Hospital Medical Center, The Trustees of Columbia UniversityInventors: Jonathan Matthew Barasch, Prasad Devarajan, Thomas L.

Publication number: 20100233739Abstract: In one embodiment, the present invention is directed to methods for diagnosis of urinary tract obstruction (UTO), and to methods for distinguishing between unilateral and bilateral UTO. In some aspects, the diagnostic methods of the invention are based on determining whether a bodily fluid sample, such as a urine sample, contains an amount of NGAL protein that exceeds or is less than a certain threshold level, or that falls within a certain range. The present invention also provides diagnostic kits for the diagnosis of UTO and for distinguishing between unilateral and bilateral UTO.Type: ApplicationFiled: February 12, 2010Publication date: September 16, 2010Inventors: Jonathan BARASCH, Thomas L.
