Abstract
Tobacco smoking is highly prevalent among people living with HIV (PLWH), yet there is a lack of data on smoking behaviours and effective treatments in this population. Understanding factors influencing tobacco smoking and cessation is crucial to guide the design of effective interventions. This systematic review and meta-analysis of studies conducted in both high-income (HICs) and low- and middle-income countries (LMICs) synthesised existing evidence on associated factors of smoking and cessation behaviour among PLWH. Male gender, substance use, and loneliness were positively associated with current smoking and negatively associated with smoking abstinence. The association of depression with current smoking and lower abstinence rates were observed only in HICs. The review did not identify randomised controlled trials conducted in LMICs. Findings indicate the need to integrate smoking cessation interventions with mental health and substance use services, provide greater social support, and address other comorbid conditions as part of a comprehensive approach to treating tobacco use in this population. Consistent support from health providers trained to provide advice and treatment options is also an important component of treatment for PLWH engaged in care, especially in LMICs.

Abstract
More than 40% of people with human immunodeficiency virus (PWH) in the United States smoke tobacco cigarettes. Among those on antiretroviral therapy, smoking decreases life expectancy more than human immunodeficiency virus (HIV) itself. Most PWH who smoke want to quit, but tobacco dependence treatment has not been widely integrated into HIV care. This article summarizes the epidemiology of tobacco use among PWH, health consequences of tobacco use and benefits of cessation in PWH, and studies of treatment for tobacco dependence among the general population and among PWH. We provide practical guidance for providers to treat tobacco dependence among PWH. A 3-step Ask-Advise-Connect framework includes asking about tobacco use routinely during clinical encounters, advising about tobacco cessation with emphasis on the benefits of cessation, and actively connecting patients to cessation treatments, including prescription of pharmacotherapy (preferably varenicline) and direct connection to behavioral interventions via telephone quitline or other means to increase the likelihood of a successful quit attempt.

Abstract
BACKGROUND Smoking-related illnesses are the leading cause of death among people with HIV (PWH). Yet, there are few effective evidence-based interventions that help PWH quit smoking. The group-based program Positively Smoke Free is a biobehavioral cessation intervention for PWH with a growing evidence base. This study builds on prior work of Positively Smoke Free and addresses numerous weaknesses of prior trials for this population. We describe the Positively Quit Trial, a randomized controlled trial comparing a videoconferencing delivered Positively Smoke Free intervention to an attention-matched condition, assessing cessation over a 1-year period. METHODS This attention-matched, randomized (1:1) controlled trial compares Positively Smoke Free Video-Groups to an updated version of Healthy Relationship Video-Groups. Participants are PWH, aged 18 years and older, who smoke at least one cigarette per day. All are offered nicotine replacement therapy patches and given brief advice to quit. Participants are enrolled in 12 group sessions focusing on either smoking cessation for PWH or broader topics regarding living healthy with HIV; in both conditions, Social Cognitive Theory is the guiding theoretical framework. Participants complete assessments at baseline, days 42, 90, 180, and 360; self-reported abstinence is verified with a video-observed cheek swab sent to a lab and tested for cotinine. PRIMARY OUTCOMES Biochemically confirmed 7-day point prevalence smoking abstinence at day 360 is the primary outcome. Cost per quit, sustained abstinence at various timepoints, and biochemical confirmed abstinence at three and six months are secondary outcomes. Effects of smoking cessation on CD4 and virologic suppression are also explored.

Abstract
Introduction: Chronic obstructive pulmonary disease (COPD) is more prevalent in people with HIV (PWH) than in the general population and leads to an increased burden of morbidity and mortality in this population. The mechanisms behind COPD development and progression in PWH are not fully elucidated, and there are no PWH-specific guidelines for COPD management. Areas covered: The goal of this broad narrative review is to review the epidemiology of COPD in PWH globally, highlight proposed pathways contributing to increased COPD prevalence and progression in PWH, discuss structural and functional changes in the lungs in this population, assesses the excess mortality and comorbidities in PWH with COPD, and address management practices for this unique population. Expert opinion: Understanding how a chronic viral infection leads to COPD, independent of cigarette smoking, is of critical scientific importance. Further research should focus on the pathophysiology of the interaction between HIV and COPD, and determine the role of disease-modifying risk factors such as opportunistic pneumonia and air pollution, as well as generate data from randomized clinical trials on the safety and efficacy of specific therapies for this vulnerable patient population.

Abstract
INTRODUCTION Smoking is a key determinant of mortality among people living with HIV (PLWH). METHODS To better understand the effects of smoking cessation interventions in PLWH, we conducted a pooled analysis of four randomized controlled trials of hospital-initiated smoking interventions conducted through the Consortium of Hospitals Advancing Research on Tobacco (CHART). In each study, cigarette smokers were randomly assigned to usual care or a smoking cessation intervention. The primary outcome was self-reported past 30-day tobacco abstinence at 6-month follow-up. Abstinence rates were compared between PLWH and participants without HIV and by treatment arm, using both complete-case and intention-to-treat analyses. Multivariable logistic regression was used to determine the effect of HIV status on 6-month tobacco abstinence and to determine predictors of smoking cessation within PLWH. RESULTS Among 5550 hospitalized smokers, there were 202 (3.6%) PLWH. PLWH smoked fewer cigarettes per day and were less likely to be planning to quit than smokers without HIV. At 6 months, cessation rates did not differ between intervention and control groups among PLWH (28.9% vs. 30.5%) or smokers without HIV (36.1% vs. 34.1%). In multivariable regression analysis, HIV status was not significantly associated with smoking cessation at 6 months. Among PLWH, confidence in quitting was the only clinical factor independently associated with smoking cessation (OR 2.0, 95% CI = 1.4 to 2.8, p < .01). CONCLUSIONS HIV status did not alter likelihood of quitting smoking after hospital discharge, whether or not the smoker was offered a tobacco cessation intervention, but power was limited to identify potentially important differences. IMPLICATIONS PLWH had similar quit rates to participants without HIV following a hospital-initiated smoking cessation intervention. The findings suggest that factors specific to HIV infection may not influence response to smoking cessation interventions and that all PLWH would benefit from efforts to assist in quitting smoking.

Abstract
Smoking is highly prevalent among people living with HIV (PLWH) and increases cardiovascular risk. Pharmacotherapies such as nicotine replacement therapy (NRT), bupropion, and varenicline help to reduce smoking, though rates of receipt among PLWH compared with HIV-uninfected persons are unknown. Among 814 PLWH and 908 uninfected patients enrolled in the Veterans Aging Cohort Study (2012-2017) who reported current smoking, we used marginal multivariable log-linear regression models to estimate adjusted relative risks (ARR) of receiving pharmacotherapy by HIV status. We also assessed patient-level factors associated with pharmacotherapy receipt within each group. In multivariable analyses, receipt of NRT was less likely among PLWH relative to uninfected participants (ARR 0.77, 95% CI 0.67, 0.89). In both populations, documented mental health disorders and contemplation to quit were associated with greater likelihood of receiving pharmacotherapy. Further research is needed to explore potential treatment disparities.

Abstract
Compared to the general population, persons living with HIV (PLWH) have higher rates of tobacco use and an increased risk of morbidity from tobacco-related diseases. We conducted a single-arm pilot study of the real-world feasibility of integrating a smoking cessation decisional algorithm within routine clinic visits to engage non-treatment-seeking smokers in smoking cessation therapies. Smokers had an initial study visit during routine care followed by phone contacts at one and three months. Participants completed a baseline survey, followed by the algorithm which resulted in a recommendation for a smoking cessation medication, which was prescribed during the visit. Follow-up phone surveys assessed changes in smoking behavior and use of cessation medications at 1 and 3 months. Participants' (N = 60) self-reported smoking decreased from a baseline average of 14.4 cigarettes/day to 7.1 cigarettes/day at 3 months (p = .001). Nicotine dependence (FTND) decreased from 5.6 at baseline to 3.6 at 3 months (p < .001). Twenty-seven (45%) made a 24-h quit attempt and 39 (65%) used cessation medication. Insurance prior-authorization delayed medication receipt for seven participants and insurance denial occurred for one. Motivational status did not significantly influence outcomes. The algorithm was successful in engaging participants to use cessation medications and change smoking behaviors.

Abstract
PURPOSE OF REVIEW The purpose of this review is to summarize and synthesize recent data on the risk of ischemic heart disease (IHD) in HIV-infected individuals. RECENT FINDINGS Recent studies in the field demonstrate an increasing impact of cardiovascular disease (CVD) on morbidity and mortality in HIV relative to AIDS-related diagnoses. Studies continue to support an approximately 1.5 to two-fold increased risk of IHD conferred by HIV, with specific risk varying by sex and virologic/immunologic status. Risk factors include both traditional CVD risk factors and novel, HIV-specific factors including inflammation and immune activation. Specific antiretroviral therapy (ART) drugs may increase CVD risk, yet the net effect of ART with viral suppression is beneficial with regard to CVD risk. Management of cardiovascular risk and prevention of CVD is complex, because current general population strategies target traditional CVD risk factors only. Extensive investigation is being directed at developing tailored CVD risk prediction algorithms and interventions to reduce CVD risk in HIV. SUMMARY Increased IHD risk is a significant clinical and public health challenge in HIV. The development and application of HIV-specific interventions to manage CVD risk factors and reduce CVD risk will improve the long-term health of this ageing population.

Abstract
INTRODUCTION The prevalence of smoking among people living with HIV/AIDS (PLWHA) remains higher than the general population. Life expectancy among PLWHA has increased over the past decade, however, PLWHA who smoke will die younger than their non-smoking peers. The primary aim of this pilot study was to examine the effects of warm handoff versus fax referral to the quitline for smoking cessation among hospitalized smokers living with HIV/AIDS. METHODS 25 smokers with a diagnosis of HIV/AIDS hospitalized at a Midwestern academic medical center in 2012-2013 (19 male; mean age=47.7; 48% African-American) were identified, approached, and randomized to one of two treatment arms. At the bedside for patients in warm handoff, staff telephoned the quitline for on-the-spot enrollment and counseling. Participants randomized to fax were fax-referred to the quitline on the day of discharge. The quitline provided continued outpatient counseling to participants in both conditions. The main outcome was verified tobacco abstinence at 6-months post randomization. RESULTS Enrollment and participation in quitline counseling was high among both warm handoff (100%) and fax-referred (71.4%) PLWHA participants. Nearly all completed follow up for outcome data collection at 6months. Verified abstinent rates were 45.5% in warm handoff versus 14.3% in fax referral at 6months (not significant). CONCLUSIONS Hospitalized smokers living with HIV/AIDS were highly engaged in quitline services. Warm handoff seems a promising intervention for hospitalized PLWHA that requires further exploration. Clinical Trials Registration NCT01305928.

Abstract
Importance Lung cancer has become a leading cause of death among people living with human immunodeficiency virus (HIV) (PLWH). Over 40% of PLWH in the United States smoke cigarettes; HIV independently increases the risk of lung cancer. Objective To project cumulative lung cancer mortality by smoking exposure among PLWH in care. Design Using a validated microsimulation model of HIV, we applied standard demographic data and recent HIV/AIDS epidemiology statistics with specific details on smoking exposure, combining smoking status (current, former, or never) and intensity (heavy, moderate, or light). We stratified reported mortality rates attributable to lung cancer and other non-AIDS-related causes by smoking exposure and accounted for an HIV-conferred independent risk of lung cancer. Lung cancer mortality risk ratios (vs never smokers) for male and female current moderate smokers were 23.6 and 24.2, respectively, and for those who quit smoking at age 40 years were 4.3 and 4.5. In sensitivity analyses, we accounted for nonadherence to antiretroviral therapy (ART) and for a range of HIV-conferred risks of death from lung cancer and from other non-AIDS-related diseases (eg, cardiovascular disease). Main Outcomes and Measures Cumulative lung cancer mortality by age 80 years (stratified by sex, age at entry to HIV care, and smoking exposure); total expected lung cancer deaths, accounting for nonadherence to ART. Results Among 40-year-old men with HIV, estimated cumulative lung cancer mortality for heavy, moderate, and light smokers who continued to smoke was 28.9%, 23.0%, and 18.8%, respectively; for those who quit smoking at age 40 years, it was 7.9%, 6.1%, and 4.3%; and for never smokers, it was 1.6%. Among women, the corresponding mortality for current smokers was 27.8%, 20.9%, and 16.6%; for former smokers, it was 7.5%, 5.2%, and 3.7%; and for never smokers, it was 1.2%. ART-adherent individuals who continued to smoke were 6 to 13 times more likely to die from lung cancer than from traditional AIDS-related causes, depending on sex and smoking intensity. Due to greater AIDS-related mortality risks, individuals with incomplete ART adherence had higher overall mortality but lower lung cancer mortality. Applying model projections to the approximately 644 200 PLWH aged 20 to 64 in care in the United States, 59 900 (9.3%) are expected to die from lung cancer if smoking habits do not change. Conclusions and Relevance Those PLWH who adhere to ART but smoke are substantially more likely to die from lung cancer than from AIDS-related causes.

Abstract
BACKGROUND In the United States, >40% of people infected with human immunodeficiency virus (HIV) smoke cigarettes. METHODS We used a computer simulation of HIV disease and treatment to project the life expectancy of HIV-infected persons, based on smoking status. We used age- and sex-specific data on mortality, stratified by smoking status. The ratio of the non-AIDS-related mortality risk for current smokers versus that for never smokers was 2.8, and the ratio for former smokers versus never smokers was 1.0-1.8, depending on cessation age. Projected survival was based on smoking status, sex, and initial age. We also estimated the total potential life-years gained if a proportion of the approximately 248 000 HIV-infected US smokers quit smoking. RESULTS Men and women entering HIV care at age 40 years (mean CD4+ T-cell count, 360 cells/µL) who continued to smoke lost 6.7 years and 6.3 years of life expectancy, respectively, compared with never smokers; those who quit smoking upon entering care regained 5.7 years and 4.6 years, respectively. Factors associated with greater benefits from smoking cessation included younger age, higher initial CD4+ T-cell count, and complete adherence to antiretroviral therapy. Smoking cessation by 10%-25% of HIV-infected smokers could save approximately 106 000-265 000 years of life. CONCLUSIONS HIV-infected US smokers aged 40 years lose >6 years of life expectancy from smoking, possibly outweighing the loss from HIV infection itself. Smoking cessation should become a priority in HIV treatment programs.
