Eligibility Criteria

18 Years - 59 Years (Adult)All SexesAccepts Healthy Volunteers

Inclusion Criteria:

  • HIV infection for a period of 1 year or greater
  • Regular use of high-potency antiretroviral therapy for at least one year

Exclusion Criteria:

  • Individuals who are physically active

Arm 2

Arm Type

Active Comparator

Placebo Comparator

Arm Label

Beetroot juice

Placebo beet juice (Nitrate depleted)

Arm Description

Outcomes

Primary Outcome Measures

Skeletal Muscle Oxygenation
Changes in skeletal muscle oxygenation in response to exercise will be evaluated by using a near-infrared spectroscopy device.
Brachial artery flow-mediated dilatation
The brachial artery flow-mediated dilation will be evaluated by using an ultrasound device.

Secondary Outcome Measures

Urinary nitrate concentrations
Analysis of nitrate in urine will be performed by using high-performance liquid chromatography system.

5. Study Description

Brief Summary
Administration of antiretroviral therapy has brought benefits for infective human immunodeficiency virus-1 (HIV-1)-patients, reducing the number of AIDS-related morbidity and mortality. However, it is responsible for intensifying complications triggered by the chronic inflammatory state associated with virus infection, such as cardiovascular diseases. The current study evaluated effects of single dose (140mL) of Beetroot Juice (BJ) on macro and microvascular endothelial function in HIV-1-patients undergoing antiretroviral terapy, once BJ was shown to be effective in improving these physiological parameters in uninfected individuals.
