Brief Summary:
People that are infected with HIV appear to be especially susceptible to the adverse effects of cigarette smoking. The purpose of this study is to determine if quitting smoking by using a specialized smoking cessation treatment can prevent one from developing accelerated lung damage, particularly emphysema.

Condition or disease Intervention/treatment Phase
Smoking HIV Infections Drug: Varenicline tartrate Drug: Nicotine Replacement Therapy Other: Biological Control Behavioral: Motivational Interview Not Applicable

Detailed Description:
HIV-infected smokers are at increased risk for life-threatening diseases, such as pneumonia. To date, very little is known about the tobacco consumption characteristics of this at-risk population of smokers, but it has been well documented that they are at high risk for smoking-related co-morbidities. In addition, few effective cessation strategies have been described in HIV-infected populations. A specialized smoking cessation that combines recommendations from an existing scientifically-valid clinical guideline with Motivational Interviewing a new pharmacotherapeutic agent, may be an effective mechanism to apply to this vulnerable population of smokers. This initial, efficacy investigation has the potential to guide future treatment and research pertaining to tobacco cessation, respiratory illness and HIV.

Primary Outcome Measures :
  1. To develop and evaluate a specialized smoking cessation intervention for the treatment of nicotine dependence in HIV-seropositive smokers. [ Time Frame: 48 Months ]

Secondary Outcome Measures :
  1. To examine the effects of smoking cessation on the course of lung function decline, the prevalence of respiratory symptoms and the occurrence/progression of emphysema in a cohort of HIV-seropositive individuals. [ Time Frame: 48 Months ]
  2. To explore the effects of smoking cessation on the biology of alveolar macrophages obtained from HIV-seropositive individuals [ Time Frame: 48 Months ]
