Method of assessing pancreatic beta-cell function
View Patent ↗Biomarkers relating to pancreatic Beta-cell function, pancreatic Beta-cell glucose sensitivity, insulin resistance, and/or pancreatic Beta-cell-related disorders are provided. Methods based on the same biomarkers are also provided.
1. A method for determining and treating compromised beta-cell function in a human subject, the method comprising:
extracting small molecules from a plasma sample obtained from the human subject to produce an analytical sample;
performing chromatography, mass spectrometry, or a combination thereof on the analytical sample to determine the levels of one or more biomarkers selected from the group consisting of 2-hydroxybutyrate (2-HB) and linoleoyl lysophosphatidylcholine (L-LPC/L-GPC);
determining compromised pancreatic beta-cell function in the subject by comparing the levels of the one or more biomarkers in the sample to functional pancreatic beta-cell reference levels of the one or more biomarkers wherein higher or elevated levels of 2-hydroxybutyrate (2-HB) compared to normal beta-cell reference levels indicate beta-cell dysfunction and lower or decreased levels of linoleoyl lysoglycerophospocholine (L-LPC/L-GPC) compared to normal beta-cell reference levels indicate beta-cell dysfunction; and
administering an effective treatment to the human subject having compromised beta-cell function, wherein effective treatment comprises one or more of surgical intervention, drug treatment intervention, exercise, early-stage drug treatment, administering a therapeutic agent for compromised beta-cell function, performing bariatric surgery, administering an effective amount of L-LPC or one or more biomarkers that are lowered in a human subject with compromised beta-cell function as compared to a healthy human subject not having compromised beta-cell function.
2. The method of claim 1 , wherein comparing comprises generating a pancreatic beta-cell function score for the subject.
3. The method of claim 2 , wherein the pancreatic beta-cell function score places the subject in a range of pancreatic beta-cell function.
4. The method of claim 2 , wherein the pancreatic beta-cell function score is used to determine the probability that the subject has compromised pancreatic beta-cell function.
5. The method of claim 2 , wherein the pancreatic beta-cell function score is used to identify subjects with compromised pancreatic beta-cell function for treatment.
