Cardiometabolic Effects of Eplerenone in HIV Infection

Hepatic Steatosis Clinical Trial

Official title: Cardiometabolic Effects of Eplerenone in HIV Infection

Status Terminated

Clinical Trial Summary

Background:

People with human immunodeficiency virus (HIV) are at a high risk of getting visceral or deep belly fat. Visceral fat can cause health problems like heart or liver disease. Researchers want to see if a blood pressure drug can help by blocking a hormone in the body.

Objective:

To see if eplerenone reduces fat stored in the heart muscle and liver in people with HIV and increased visceral fat.

Eligibility:

Adults ages 18 75 with HIV and increased waist circumference. Increased waist circumference is defined as more than 40 inches in men and more than 35 inches in women.

Design:

Participants will be screened with:

Physical exam

Medical history

Blood tests

Measurements of hips, waist, legs, arms, shoulders, and neck

Magnetic resonance imaging (MRI) scan. They will lie on a table that slides into a machine.

Electrocardiogram (EKG) to measure heart electrical activity

Transient elastography, a special ultrasound to measure liver tissue stiffness

A small piece their liver collected (optional)

Participants will have a baseline visit:

Physical exam

Medical history

Blood tests

DEXA scan to measure body fat, muscle mass, and bone density. Participants will lie on a table while a very small dose of x-rays goes through the body.

Resting energy expenditure (REE). This measures the amount of oxygen breathed in and carbon dioxide breathed out.

Participants will get a 1-week supply of eplerenone. They will take one pill per day.

Participants will have a follow-up visit 1 week later. They will have:

Physical exam

Medical history

Blood tests

23-week supply of eplerenone

Participants will have 5 more follow-up visits.

Participants will have a final study visit, repeating many of the screening and baseline tests.

Clinical Trial Description

HIV-infected individuals are at higher risk than uninfected people for developing cardiovascular disease. Visceral adipose tissue is also increased in HIV-infected people compared to uninfected individuals. Animal studies suggest that blockade of the mineralocorticoid receptor (MR) may have beneficial effects on cardiovascular and metabolic parameters via inhibition of adipocyte differentiation and triglyceride accumulation. We will examine the effects of the MR antagonist eplerenone (50 mg daily) on HIV-infected adults with abdominal fat accumulation in a 24-week, open-label, proof-of-concept study. Magnetic resonance imaging will be conducted at screening and the final study visit to evaluate cardiac and hepatic steatosis. We anticipate that blocking the effects of increased aldosterone secretion with eplerenone will significantly reduce intramyocardial lipid content and hepatic steatosis in this population. These effects may be accompanied by decreases in visceral adipose tissue, and improvements in dyslipidemia and inflammation, thereby improving cardiovascular health. ;
