NCT03479671

Brief Summary

The primary goal of this study is to determine the dose of fatty acids that acutely induces mild insulin resistance in healthy volunteers. We hypothesize that a low-dose of fatty acid infusion (Intralipid/heparin) will cause a mild insulin resistance. The dose of fatty acid infusion that reliably causes mild insulin resistance will be selected for use in future studies.

Gender Eligibility DetailsMale or Female at birth.
Healthy VolunteersYes
Age GroupsAdult (18-64)

You may qualify if:

  • Subjects who are able to provide written informed consent and to comply with the procedures of the study protocol

You may not qualify if:

  • History of diabetes
  • History of diabetes in more than one first-degree relative
  • Body mass index (BMI) \<19 or \>27 kg/m2
  • HbA1c \>5.7%
  • Blood Pressure: systolic \>160 mmHg or diastolic \> 100 mmHg
  • Baseline hemoglobin concentration \< 11 g/dl in women and \< 12 g/dl in men
  • Estimated glomerular filtration rate \< 55 ml/min/1.73 m2 (calculated using the subject's measured serum creatinine and the Modification of Diet in Renal Disease \[MDRD\] study estimation formula).
  • Presence of soy or egg allergies (due to possible reactions with fat infusate)
  • For female participants: Positive pregnancy test, presently breast-feeding, or unwillingness to use effective contraceptive measures for the duration of the study. Oral contraceptives, Norplant®, Depo-Provera®, and barrier devices with spermicide are acceptable contraceptive methods; condoms used alone are not acceptable.
  • Known active alcohol or substance abuse
  • Use of tobacco within the previous year
  • Severe co-existing cardiac disease, characterized by any one of these conditions:
  • history of myocardial infarction within past 6 months;
  • history of ischemia on functional cardiac exam within the last year;
  • history of left ventricular ejection fraction \< 30%.
  • +8 more criteria

BASIC SCIENCE
Intervention Model
SEQUENTIAL
Model Details: Baseline insulin sensitivity will be measured in healthy volunteers, and then 1-3 weeks later insulin sensitivity will be measured in response to a low-dose fatty acid infusion. If there is no response to this low-dose infusion, then 1-3 weeks later insulin sensitivity will be measured in response to a medium-dose fatty acid infusion.
