Mitigating the Pro-inflammatory Phenotype of Obesity (MAPLE)
The purpose of this study is to examine the hypothesize that 4 weeks of sympathetic nerve activity (SNA) inhibition (oral clonidine) will cause a significant reduction in circulating blood concentrations and endothelial cell expression of inflammatory markers (e.g., TNF-α, IL-6).
Our study is a prospective study using a randomized, double-blinded design to test 4 weeks of SNA blockade (oral clonidine) compared with a BP-lowering control condition (diuretic, hydrochlorothiazide) or a placebo.

Detailed Description
- Using a randomized, double-blinded, parallel-design approach, we hypothesize that 4 weeks of SNA blockade (oral clonidine) will cause a significant reduction in expression of inflammatory markers in blood, endothelial cells, and central adipose compared with a BP-lowering control condition using hydrochlorothiazide (HCTZ) and a separate placebo treatment.
- Determine the extent to which inflammation in the body is caused by elevated sympathetic nerve activity

---|---|
PLACEBO_COMPARATOR: Placebo
KU Investigational Pharmacy will provide the drug prescription bottle with 35-day supply of placebo to the research coordinator to give to the research participant. The placebo is an inert substance with no intended medical value and is used as a negative control for comparison with the study drug. Participants will receive a Placebo Pill; has no active ingredients but is made to look like the study drug. |
Will receive a 4 week supply (35 days) of Placebo Pills; has no active ingredients but is made to look like the study drug.
|
EXPERIMENTAL: Clonidine
KU Investigational Pharmacy will provide the drug prescription bottle with 35-day supply of clonidine to the research coordinator to give to the research participant. Planned use in this study
|
Will receive 4 week supply (35 days) of Clonidine Pills (0.1 mg twice/day) Planned use in this study
