Trial Outcomes & Findings for A Study to Compare Brachial Artery Reactivity and Cardiovascular Risk of a Treatment Simplification by Darunavir/Ritonavir (DRV/r) 800/100 mg Versus a Triple Combination Therapy Containing DRV/r in HIV-1 Infected Patients (NCT NCT01391013)

NCT ID: NCT01391013

Last Updated: 2013-06-27

Results Overview

Brachial artery FMD is calculated as the percentage increase in brachial artery diameter with hyperemia (an increase in the quantity of blood flow to a body part) induced relative to the resting brachial artery diameter. Percentage of brachial artery diameter is measured as FMD diameter/basal diameter.

The Homeostatic Model Assessment (HOMA) is a method used to quantify insulin resistance and beta-cell function. HOMA-IR is reflected in the diminished effect of insulin on hepatic glucose production. HOMA-IR is calculated as: (Glucose \[mg/dL\] X Insulin \[pmol/L\]) / (405 X 6.945). Higher scores indicate worse insulin resistance.

The Framingham Risk Score is used to estimate the 10-year cardiovascular risk of a participant. It is calculated according to age, laboratory values of total cholesterol and HDL cholesterol, smoking status, and systolic blood pressure. The framingham risk score is calculated as: for males: 0 point (1 percentage) up to 17 points (30 percentages); whereas for females: 0 to 9 points (1 percentage) up to 25 points (30 percentage). Higher scores indicate high cardiovascular risk.

T score is used to calculate bone mineral density (calcium and other types of minerals) in an area of the bone. T score is the number of standard deviations above or below the mean for a healthy 30 year old adult of the same sex and ethnicity as a participant. This score is calculated from participant's age, gender and race and skeletal site. T score has a mean of '50' and a standard deviation of '10'. T score lower than its mean indicate low bone mineral density.
