Publication number: 20220187293Abstract: Embodiments provide for devices and methods of use for detecting one or more biomarkers of rheumatic disease in a subject. In an example, a method includes detecting citrullinated human serum albumin (HSA) in a biological sample via obtaining the biological sample from a subject, applying the biological sample to a lateral flow device under conditions sufficient for formation of an immunocomplex comprising anti-HSA antibody coupled to citrullinated HSA that is in turn coupled to anti-citrullinated HSA autoantibody, determining a quantity of the immunocomplex, and managing rheumatic disease associated with the subject. In this way, rheumatic disease may be effectively managed based at least in part on amounts of citrullinated HSA detected via rapid point-of-care test methodology.Type: ApplicationFiled: December 10, 2021Publication date: June 16, 2022Applicant: DIABETOMICS, INC.Inventors: Srinivasa R.

Patent number: 10996228Abstract: Disclosed herein are screening tools for fetal/maternal wellness, such as biomarkers for assessing preeclampsia. More specifically, methods are disclosed for assessing the risk of preeclampsia in a subject, the methods including obtaining a first serum sample from the subject, determining a level of glycosylated fibronectin (GlyFn) in the first serum sample, and comparing the determined level of GlyFn with a control value, wherein an elevation in the determined level of GlyFn in the first serum sample relative to the control value indicates that the subject is at increased risk of preeclampsia. Also disclosed are methods of determining the risk of preeclampsia in a subject during a first, second, or third trimester, methods of assessing severity and progression of preeclampsia and complications of a risk of low birth weight or HELLP syndrome.Type: GrantFiled: December 6, 2017Date of Patent: May 4, 2021Assignee: DIABETOMICS, INC.Inventors: Srinivasa R. Nagalla, Eric S. Bean

Patent number: 9383370Abstract: Embodiments herein relate to the field of screening tools for fetal/maternal wellness, and, more specifically, to biomarkers for gestational diabetes. In various embodiments, the methods may provide non-invasive and minimally-invasive screening tools for gestational diabetes that involve detection of changes in a proteomic profile of a test sample relative to a reference sample. In particular embodiments, the method may include determining whether a proteomic profile of a test sample from the subject includes at least one expression signature characteristic of gestational diabetes, wherein the proteomic profile comprises information on the expression of glycosylated fibronectin and glycosylated PSG, for example information on levels of fibronectin-SNA or a fibronectin-antibody complex, and PSG-AAL or a PSG-antibody complex.Type: GrantFiled: October 16, 2014Date of Patent: July 5, 2016Assignee: Diabetomics, Inc.Inventor: Srinivasa R.

Patent number: 9383352Abstract: Disclosed herein are methods and tests for diagnosing and/or monitoring a metabolic condition such as diabetes in a subject, wherein the methods and tests measure salivary glycoproteins. Some of the methods are based on the oxidation of glycoproteins in a sample from the subject, such as saliva or urine, for example using sodium metaperiodate, and then detecting the aldehydes generated during oxidation using a chemical detection method. Also disclosed are kits and lateral flow devices for detecting glycoproteins in a saliva sample.Type: GrantFiled: March 26, 2014Date of Patent: July 5, 2016Assignee: Diabetomics, Inc.Inventors: Srinivasa R.
