Physiologic Investigation of the Renin Angiotensin Aldosterone Axis in HIV

NCT01407237 · Status: COMPLETED · Type: OBSERVATIONAL · Enrollment: 30

Summary

The purpose of this study is to see if individuals with HIV-infection, particularly those with increased belly fat, have abnormalities in the renin angiotensin aldosterone axis. Renin, angiotensin, and aldosterone are hormones that regulate salt and water balance in the body, and they may also have effects on sugar metabolism and cardiovascular health. There is some evidence that individuals with HIV-associated abdominal fat accumulation may have increased aldosterone, which may contribute to abnormalities in sugar metabolism and increased cardiovascular disease seen in HIV. The purpose of this study is the measure renin, angiotensin, and aldosterone activity, as well as other hormonal axes, in people with and without HIV infection, and with and without increased belly fat. The investigators hypothesize that aldosterone will be increased in HIV-infected individuals compared to those without HIV-infection, and that aldosterone will be further increased in HIV-infected individuals with increased abdominal fat compared to those without abdominal fat accumulation.

Conditions

  • HIV-infection

Interventions

DRUG

Angiotensin II Infusion

Angiotensin II (Bachem) will be infused at 0.3 ng/kg/min for 30 minutes, then 1.0 ng/kg/min for 30 minutes, then 3.0 ng/kg/min for 30 minutes; at baseline and at each infusion concentration, serum aldosterone will be measured. BP and heart rate will be monitored at baseline and every 2 minutes during the infusion.
