Patent number: 10054600Abstract: Diagnostic biomarker panel, method, kit, and device for diagnosing the severity and/or prognosis of cirrhosis are provided. More specifically, the invention provides a novel biomarker panel correlating to HVPG and esophageal varices. The invention further provides a biomarker panel and non-invasive test methods that predict non-clinically significant portal hypertension HVPG and non-clinically significant esophageal varices when the expression of the biomarker panel correlates with HVPG of less than 12 mmHg. The invention further provides that the patients with the expression of the biomarker panel correlating to non-clinically significant HVPG and esophageal varices can be excluded from undergoing esophagogastroduodenoscopy (EGD) screening and those correlating to HVPG equal to or greater than 12 mmHg are indicated for EGD.Type: GrantFiled: May 22, 2014Date of Patent: August 21, 2018Assignee: The Regents of the University of CaliforniaInventors: Mario Chojkier, Martina Buck
