The Cleveland Cardiometabolic Cohort

Recruiting
Conditions
Lipodystrophy
HIV
Interventions
Diagnostic Test: Dual-energy X-ray absorptiometry
Registration Number
NCT03059121
Lead Sponsor
University Hospitals Cleveland Medical Center
Brief Summary

In this observational study, the investigators will examine the changes in body composition in HIV-infected subjects before and after initiation of HIV treatment, and look at the correlations with changes in cardiometabolic indices such as endothelial function and coronary calcium scoring.

Detailed Description

The effects of lifestyle factors on body composition changes after antiretroviral therapy (ART) are unknown, and as such, investigators will use this prospective observational cohort to study relationships between lifestyle factors, including diet, physical activity and illicit drug use, with changes in body composition after ART. In addition, the effect of the body fat changes will be correlated to changes in cardiometabolic indices such as endothelial function and coronary calcium scoring.

Primary Outcome Measures
NameTimeMethod
Body composition measuresBaseline, 6-month, 1 year, 2 year, 3 year, 4 year, 5 year

Assessed using DEXA (dual energy x-ray absorptiometry) scans which will be quantifying total body fat

Secondary Outcome Measures
NameTimeMethod
endothelial function measuresBaseline, 6-month, 1 year, 2 year, 3 year, 4 year, 5 year

Assessed using EndoPAT (values reported as a reactive hyperemia index RHI)

calcium score measuresBaseline, 6-month, 1 year, 2 year, 3 year, 4 year, 5 year

Assessed using CT scans

Metabolic syndromeBaseline, 6-month, 1 year, 2 year, 3 year, 4 year, 5 year

Metabolic syndrome will be defined using the following measures: central obesity, serum triglycerides , serum high-density lipoprotein (HDL); cholesterol levels and fasting plasma glucose

Resting Energy Expenditure (REE) measuresBaseline, 6-month, 1 year, 2 year, 3 year, 4 year, 5 year

Assessed using a BodyGem REE calculator (values in KCal)

central obesityBaseline, 6-month, 1 year, 2 year, 3 year, 4 year, 5 year

measured with waist circumference using a tape measure (in cm)

Lipids measuresBaseline, 6-month, 1 year, 2 year, 3 year, 4 year, 5 year

used measuring blood levels of triglycerides (mg/dL); serum high-density lipoprotein (mg/dL) ; cholesterol (mg/dL); low density lipoprotein (mg/dL)

Fasting plasma glucose measuresBaseline, 6-month, 1 year, 2 year, 3 year, 4 year, 5 year

fasting plasma glucose test is performed after a person has fasted for at least 8 hours (measured in mg/dL)
