Collaborating Sponsors:

National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK)

Conditions:

Insulin Sensitivity

Eligibility:

All Genders

18-80 years

Phase:

NA

Brief Summary

This study aims to evaluate the effect of hepatic ultrasound treatment on changes from baseline in whole-body insulin sensitivity during a hyperinsulinemic, euglycemic clamp (HE Clamp).

Detailed Description

Drop-outs will be replaced; data will be used as much as can be. Subjects will undergo a Screening visit to assess eligibility and will then be scheduled to undergo 2 outpatient US treatment visits. ...

Eligibility Criteria

Inclusion

  • Type 2 diabetic (T2D) subjects must be aged 18-80 and must be able to provide written informed consent
  • All subjects must have had T2D for at least 3 months prior to study enrollment. All subjects must be either on diet and exercise or oral antidiabetic agents alone, not on insulin or any form of insulin or GLP-1 receptor agonists.
  • Subjects must demonstrate:
  • A past medical history of abnormal glucose control and carry a diagnosis of T2D according to current ADA criteria:
  • A fasting plasma glucose (FPG) level of 126 mg/dL (7.0 mmol/L) or higher, or
  • A 2-hour plasma glucose level of 200 mg/dL (11.1 mmol/L) or higher during a 75-g oral glucose tolerance test (OGTT), or
  • A random plasma glucose of 200 mg/dL (11.1 mmol/L) or higher in a patient with classic symptoms of hyperglycemia or hyperglycemic crisis or
  • A hemoglobin A1c (HbA1c) level of 6.5% or higher.
  • Be willing to carry a continuous glucose monitor for at least 10 days.
  • Be willing to follow all required instructions by study personnel and appear for the required laboratory assessments, including euglycemic clamps and OGTT.

Exclusion

  • BMI \>40kg/m2.
  • Untreated proliferative retinopathy
  • Creatinine clearance \< 60 ml/min/1.73 m2.
  • Serum creatinine ≥1.5 mg/dL
  • Positive pregnancy test, or presently breast-feeding, or failure to follow effective contraceptive measures
  • Active infection including hepatitis C, hepatitis B, HIV,
  • Any history of Active alcohol abuse
  • History of non-adherence to prescribed regimens
  • Baseline Hgb \< 10.5 g/dL in females, or \< 13 g/dL in males
  • History of coagulopathy or medical condition requiring long-term anticoagulant therapy (low-dose aspirin treatment is allowed)
  • Co-existing cardiac disease with active medication titration. Patients on stable meds without active cardiac complications permitted.
  • Liver function tests outside of 3xUL of normal range
  • GI disorders potentially interfering with the ability to absorb oral medications and h/o upper GI surgery that might have changed anatomy in the target areas.
  • Any medical condition or medication that, in the opinion of the investigators, will interfere with the safe completion of the study or study outcomes.
