Brief Summary
This study tests whether withdrawal-related cognitive deficits increase smoking relapse among HIV-infected (HIV+) vs. HIV-uninfected smokers (HIV-). Adult smokers (N=300; 150 HIV+, 150 HIV-) will complete 2 sessions to assess cognition (24h abstinence vs. smoking-as-usual; order counterbalanced; weeks 0-2). Subjects will then receive smoking cessation counseling and open label transdermal nicotine (weeks 3-12). Outcomes are: 1) cognition; and 2) abstinence rates at the end-of-treatment.

Outcome Measures
Primary Outcomes (1)
Cognitive Function
Cognitive function will be assessed at the Lab session 1 and lab session 2 visits as well as End of Treatment. Participants will complete measures of executive function, verbal learning and memory and response inhibition. The primary outcome is the change in cognitive function lab session 1, lab session 2, and End of Treatment measured by a composite score (calculated by averaging individual z-scores). Z-scores were calculated using the Stroop interference score (executive function; measured in milliseconds), the delayed recall score from the Hopkins Verbal Learning Test (verbal learning and memory), and the Stop signal reaction time from the Stop Signal Task (response inhibition, measured in milliseconds). A composite score will be created by computed standardized z-scores for each measure (where the mean is 0 and the standard deviation is 1) and then averaging the z-scores. Measures of response time were reverse coded such that higher z-scores indicate better cognitive performance.

Study Arms (4)
HIV+ Smoking lab session first
HIV-infected smokers: diagnosed with HIV infection and exhibiting viral load of less than or equal to 1000 copies/mL and CD4+ counts of greater than or equal to 200 cells/mm3 within 6 months prior to enrollment Randomized to complete smoking-as-usual lab session first and 24-h abstinent lab session second
HIV- Smoking lab session first
HIV-uninfected smokers: negative HIV status will be confirmed by an on-site rapid HIV blood test Randomized to complete smoking-as-usual lab session first and 24-h abstinent lab session second
HIV+ Abstinent lab session first
HIV-infected smokers: diagnosed with HIV infection and exhibiting viral load of less than or equal to 1000 copies/mL and CD4+ counts of greater than or equal to 200 cells/mm3 within 6 months prior to enrollment Randomized to complete 24-h abstinent lab session first and smoking-as-usual lab session second
HIV- Abstinent lab session first
HIV-uninfected smokers: negative HIV status will be confirmed by an on-site rapid HIV blood test Randomized to complete 24-h abstinent lab session first and smoking-as-usual lab session second
Interventions
All participants will receive nicotine patches to aid in quitting smoking. TN is available over the counter and is very well tolerated. Participants will use "the patch" in a tapering fashion as recommended by the manufacturer. Participants who smoke 10 or more cigarettes per day will adhere to the following dosing guidelines: 21 mg for 4 weeks; 14 mg for 2 weeks and 7 mg for 2 weeks. Individuals who smoke between 5 and 9 cigarettes per day will follow a modified dosing regimen: 14 mg for 6 weeks and 7 mg for 2 weeks.
Participants will attend 6 counseling sessions and receive standard smoking cessation counseling (SC).
Eligibility Criteria
Three hundred (150 HIV+ and 150 HIV-) adult male and female smokers 18 years of age or older who smoke at least 5 cigarettes per day and are interested in quitting smoking will complete the study. HIV-infected smokers have been diagnosed with HIV/AIDS and HIV-uninfected smokers will have no diagnosis of HIV, either via blood test or self-report.
You may qualify if:
- Males and females 18 years of age or older who self-report smoking at least 5 cigarettes (menthol and non-menthol) per day, on average.
- HIV status
- HIV-infected smokers: diagnosed with HIV infection and exhibiting viral load of less than or equal to 1000 copies/mL and CD4+ counts of greater than or equal to 200 cells/mm3 within 12 months prior to enrollment.
- HIV-uninfected smokers: negative HIV status will be confirmed by an on-site rapid HIV blood test.
- Able to use transdermal nicotine (TN) safely, based on a medical evaluation.
- Residing in the geographic area for at least 4 months.
- Women of childbearing potential (based on medical history) must consent to use a medically accepted method of birth control (e.g., condoms and spermicide, oral contraceptive, Depo-Provera injection, contraceptive patch, tubal ligation) or abstain from sexual intercourse during the time they are in the study and using transdermal nicotine.
- Able to communicate fluently in English.
- Capable of giving written informed consent, which includes compliance with the requirements and restrictions listed in the combined consent/HIPAA form.
You may not qualify if:
- Smoking Behavior
- Current enrollment or plans to enroll in another smoking cessation program in the next 4 months.
- Regular (daily) use of electronic cigarettes, chewing tobacco, snuff, snus, cigars, cigarillos, or pipes.
- Current use or plans to use nicotine substitutes (gum, patch, lozenge, e-cigarette) or smoking cessation treatments in the next 4 months.
- Current untreated and unstable diagnosis of substance dependence (eligible if past use and if receiving treatment and stable for at least 30 days). Current untreated and unstable diagnosis of substance abuse requires Study Physician approval.
- A positive urine drug screen for cocaine, amphetamines, methamphetamines, Phencyclidine (PCP), barbiturates, ecstasy (MDMA) at Intake (see Measures and Table 1 for details). At Lab 1 and Lab 2, positive urine drug screens will be reviewed on a case-by-case basis. The PI will determine if the participant will be excluded or allowed to reschedule the visit, at which time they must provide a negative drug screen to continue with the study.
- Current use or recent discontinuation (within last 14 days) of the following medications:
- Other smoking cessation medications (e.g. Zyban, Wellbutrin, Wellbutrin sustained release (SR), Chantix)
- a. Note: Once participants are found eligible for the study, they are instructed to only use the NRT provided to them by the study staff. If a subject reports using a non-study smoking cessation medication (including other forms of NRT), the study physician and PI will evaluate the situation and determine if it is safe for the subject to continue participation.
- Anti-psychotic medications (if used to treat psychotic symptoms. Other uses may be eligible pending physician approval).
- Daily use of opiate-containing medications for chronic pain (Duragesic/fentanyl patches, Percocet, Oxycontin). Smokers who report taking opiate-containing medications on an "as-needed" basis will be instructed to refrain from use until their study participation is over and that they will be tested to ensure they have complied with this requirement.
- Asthma medications/corticosteroids (requires physician approval)
- Anti-depressants (require physician approval)
- Females who self-report current pregnancy, planning a pregnancy during the study, or currently breastfeeding/lactating.
- Current diagnosis of unstable and untreated major depression, as determined by self-report \& Mini International Neuropsychiatric Interview (MINI) (eligible if stable for at least 30 days).
