Evaluation of Cardiovascular Effects of Smoking Cessation in HIV Patients

HIV Infections Clinical Trial

Official title:
Evaluation of Cardiovascular Effects of Smoking Cessation in HIV Infected Patients

Clinical Trial Summary

We will conduct a sub-study of "An Innovative Telephone Intervention for HIV+ Smokers," (NCT00502827) conducted by Drs. Gritz, Vidrine, and others. This is a randomized, prospective trial that will evaluate a cellular phone delivered counseling intervention versus standard of care for smoking cessation. In our sub-study, we will evaluate rates of progression in atherosclerosis in HIV/AIDS patients who quit smoking versus those who continue smoking by measuring carotid intima-media thickness(CIMT) and biomarkers of atherosclerosis at time point baseline, 1 year, and 3 year. The biomarkers measured include high-sensitivity Creactive protein, homocysteine, and IL-6. We will also evaluate rates of progression of CIMT in those who quit smoking versus those who continue smoking, based on race, sex, state of HIV disease, comorbid diseases, and lipid profile.

Clinical Trial Description

HIV/AIDS patients may have an increased risk of myocardial infarction. Traditional risk factors for coronary artery disease, including cigarette smoking, likely play a large role. The prevalence of smoking in the HIV patient population is higher than the general population. We will conduct a sub-study of "An Innovative Telephone Intervention for HIV+ Smokers," (NCT00502827) conducted by Drs. Gritz, Vidrine, and others. This is a randomized prospective trial that will evaluate a cellular phone delivered counseling intervention versus standard of care for smoking cessation. In our sub-study, we will evaluate rates of progression in atherosclerosis in HIV/AIDS patients who quit smoking versus those who continue smoking by measuring carotid intima-media thickness(CIMT) and biomarkers of atherosclerosis at time point baseline, 1 year, and 3 year. The biomarkers measured include high-sensitivity Creactive protein, homocysteine, and IL-6. We will also evaluate rates of progression of CIMT in those who quit smoking versus those who continue smoking based on race, sex, state of HIV disease, comorbid diseases and lipid profile. The central hypothesis is that smoking cessation win slow the atherosclerosis progression in HIV patients. A successful behavioral intervention is being evaluated in the parent study. The goal of this sub-study is to assess the effect of a modifiable coronary artery disease risk factor, smoking, in HIV/AIDS patients through this collaboration of cardiovascular expertise and metrics. ;
