Electronic Cigarettes as a Harm Reduction Strategy Among People Living With HIV/AIDS
April 2, 2024 updated by: NYU Langone Health
This is a research study to understand and determine the effectiveness of electronic cigarettes versus nicotine replacement therapy in adults who smoke and also live with HIV/AIDS in effort to reduce cigarette smoking.
Study Overview
Status
Active, not recruiting
Conditions
Detailed Description
People living with HIV/AIDS (PLWHA) are known to have exceptionally higher rate of cigarette smoking and very low quit rates compared to the general population.
Although a primary rationale for conducting this study is reducing health disparities among PLWHA, there is a potential benefit of the proposed work from a prevention perspective given that combustible cigarette smoking is an independent risk factor for non-adherence to ART and may decrease the effectiveness of HAART.
Smoking-related illnesses are leading causes of non-HIV/AIDS-related deaths among People Living with HIV/AIDS (PLWHA).
Electronic cigarettes (E-cigarettes) could help people reduce the harm of combustible cigarette (CC) through reductions in number of Cigarettes per Day (CPD) or quitting CC completely by addressing both nicotine and behavioral dependence.
Unlike CC, EC are not associated with coronary heart disease or myocardial infarction.
The purpose is to identify barriers and facilitators, as well as assess preliminary effectiveness of e-cigarettes as a harm reduction strategy among PLWHA.

Arms and Interventions
Participant Group / Arm |
Intervention / Treatment |
---|---|
Active Comparator: counseling + nicotine replacement therapies NRT
A research assistant (RA) trained in motivational interviewing and qualitative methods will support the PI to deliver counseling sessions and conduct interviews.
Briefly, during each visit, with help of the RA, participants will provide exhaled CO and saliva cotinine test, and complete surveys in REDCAP using a tablet, allowing programmed logic checks and skip patterns to minimize burden.
The RA will also deliver brief motivational counseling tailored to the participant's readiness to quit and arm in the study (NRT).
Participants will also receive their NRT to last them to the following visit based on their baseline smoking.
|
Nicotine patch and gum will be given to subjects in the Nicotine replacement therapy cohort every visit after providing exhaled CO/Saliva cotinine test.
The MNWS assesses symptoms associated with nicotine withdrawal (i.e., craving, irritability, anxiety, difficulty concentrating, restlessness, increased appetite or weight gain, depression, and insomnia).
The ASSIST is the Alcohol, Smoking and Substance Involvement Screening Test.
It is a brief screening questionnaire to find out about people's use of psychoactive substances (alcohol, smoking and substance involvement).
At each study visit, participants will receive counseling protocol that will be based on effective counseling manuals.
The PI will train the research assistant who will assist the PI in tailoring the manual to the target group: counseling will cover health education, social support issues, and motivational enhancement to improve self-efficacy while addressing other aspects known to contribute to smoking among PLWHA (e.g., tips on dealing with depression and feeling stigmatized particularly in relation to HIV).
|
Active Comparator: Counseling + Standardized Research E-cigarettes (SREC)
Participants in the SREC arm to practice using the SREC and give them instructions to return with their SREC and used refill tanks on every visit.
A research assistant (RA) trained in motivational interviewing and qualitative methods will support the PI to deliver counseling sessions and conduct interviews.
Briefly, during each visit, with help of the RA, participants will provide exhaled CO and saliva cotinine test, and complete surveys in REDCAP using a tablet, allowing programmed logic checks and skip patterns to minimize burden.
The RA will also deliver brief motivational counseling tailored to the participant's readiness to quit and arm in the study (SREC).
Participants will also receive their SREC to last them to the following visit based on their baseline smoking.

NIDA SREC has a case with a liquid tank.
The e-liquid is supplied in sealed disposable cartridges that deliver >300 puffs / cartridge.
The SREC uses a battery recharged via a micro USB port.
A single charge is designed to outlast the capacity of an e-liquid cartridge.
The e-liquid is "tobacco" flavored and contains nicotine.

Change in Cigarettes per Day (CPD)
Time Frame: Visit 1 (week1), Visit 2 (Week 2), Visit 3 (Week 4), Visit 4 (Week 6), Visit 5 (Week 8), Visit 6 (week 12)
|
In the e-cigarette arm, participants will be encouraged to substitute SREC (15 mg/ml nicotine in tobacco flavor) for CC in order to reduce nicotine withdrawal symptoms.
Smoking reduction will be measured by a combination of self-report, text message data and changes in CO and saliva cotinine between baseline and end of treatment.
