Sponsor Philip Diaz
Collaborator National Heart, Lung, and Blood Institute (NHLBI)
Start date June 2008
End date April 2013
Trial size 368 participants
Trial identifier NCT00701896, 2007H0173, R01HL090313


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.

Additional Information

Official title Smoking Cessation and the Natural History of HIV-Associated Emphysema
Principal investigator Philip T. Diaz, MD
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.
