Type 2 Diabetes Observational Study (DOS)

An Observational Study in Patients with T2DM

Status: Currently recruiting subjects
Required visits: Single visit
Age of participants: Greater than 50 years
Gender of participants: Male and Female

PI: Rohit Loomba, MD

IRB: #160231

This is a prospective cohort study consisting of a one-time visit by diabetic patients with optional following liver biopsy. The aim of the study is to conduct an epidemiological study of liver disorders in patients with T2DM.

During the visit, the diabetic patients will undergo a review of medical history, vitals (including body mass index, and blood pressure), physical exam, blood work, urine collection, ECG, magnetic resonance imaging (MRI), including MR proton density fat fraction (MRI-PDFF) and MR elastography, ultrasound using acoustic radiation force impulse (ARFI) imaging, and ultrasound transient elastography.  Blood work will be sent for labs relevant to traits of metabolic syndrome including markers for diabetes (hemoglobin A1C, fasting glucose) and hyperlipidemia (lipid panel). Serum, plasma, peripheral blood mononuclear cells (PBMCs), whole blood, urine, and stool will be stored for future studies. Results from history, physical exam, and MRI and ultrasound imaging will be analyzed and if they indicate the presence of nonalcoholic steatohepatitis, patients will be offered an optional liver biopsy for further assessment. All patients will be invited to continue in the study and have follow-up visits every two years for a total duration of the study of 5 years.

Results from history, physical exam, and radiographic imaging will be used together with previously available genetic data to study the genetic covariance of nonalcoholic fatty liver disease (NAFLD) and traits of the metabolic syndrome.
