Worldwide relative smoking prevalence among people living with and without HIV

A clinical overview of people living with HIV and genitourinary cancer care

The number of people living with HIV infection has been increasing globally. Administration of antiretroviral therapy is effective in controlling the infection for most patients and, as a consequence, people living with HIV (PLWH) now often have a long life expectancy. However, their risk of developing cancer - most notably virus-related cancers - has been increasing. To date, few studies have assessed the risk of genitourinary cancers in PLWH, and robust scientific data on their treatment-related outcomes are lacking. Previous studies have noted that PLWH are at a reduced risk of prostate cancer; however, low adoption and/or availability of prostate cancer screening among these patients might be confounding the validity of this finding. In genitourinary cancers, advanced stage at diagnosis and reduced cancer-specific mortality have been reported in PLWH. These data likely reflect, at least in part, the inequity of health care access for PLWH. Notably, systemic chemotherapy and/or radiotherapy could decrease total CD4+ cell counts, which could, therefore, increase the risk of morbidity and mortality from cancer treatments in PLWH. Immune checkpoint inhibitors have become the therapeutic backbone for many advanced malignancies in the general population; however, most studies validating their efficacy have excluded PLWH owing to concerns of severe adverse effects from immune checkpoint inhibitors themselves and/or related to their immunosuppressed status. To our knowledge, no genitourinary cancer survivorship programme exists that specifically caters to the needs of PLWH. By including PLWH in ongoing cancer trials, we can gain invaluable insights that will help to improve cancer care specifically for PLWH.

Factors Influencing Tobacco Smoking and Cessation Among People Living with HIV: A Systematic Review and Meta-analysis

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.

HIV-Associated Cardiovascular Disease Pathogenesis: An Emerging Understanding Through Imaging and Immunology

Cardiac abnormalities were identified early in the epidemic of AIDS, predating the isolation and characterization of the etiologic agent, HIV. Several decades later, the causation and pathogenesis of cardiovascular disease (CVD) linked to HIV infection continue to be the focus of intense speculation. Before the widespread use of antiretroviral therapy, HIV-associated CVD was primarily characterized by HIV-associated cardiomyopathy linked to profound immunodeficiency. With increasing antiretroviral therapy use, viral load suppression, and establishment of immune competency, the effects of HIV on the cardiovascular system are more subtle. Yet, people living with HIV still face an increased incidence of cardiovascular pathology. Advances in cardiac imaging modalities and immunology have deepened our understanding of the pathogenesis of HIV-associated CVD. This review provides an overview of the pathogenesis of HIV-associated CVD integrating data from imaging and immunologic studies with particular relevance to the HIV population originating from high-endemic regions, such as sub-Saharan Africa. The review highlights key evidence gaps in the field and suggests future directions for research to better understand the complex HIV-CVD interactions.

Association of age at antiretroviral therapy initiation with CD4 + : CD8 + ratio recovery among virally suppressed people with HIV

OBJECTIVE

To investigate the association of age at antiretroviral therapy (ART) initiation with CD4 +  : CD8 + T-cell ratio in virally suppressed people with HIV on long-term ART, and to characterize potential CD4 +  : CD8 + ratio recovery in this population by age.

DESIGN

A longitudinal study of people attending an HIV clinic at the Royal Free Hospital NHS Trust, London, who initiated ART between 2001 and 2015, and achieved and maintained HIV-1 viral suppression (viral load <1,000 copies/ml). The association of age group at ART initiation with CD4 +  : CD8 + ratio at 5 and 10 years was assessed.

METHODS

Multivariable linear regression was used to investigate the relationship between age at ART initiation and log CD4 +  : CD8 + ratio, adjusting for demographic factors (gender/HIV transmission route, ethnicity), baseline CD4 + count and calendar year.

RESULTS

The sample included 1859 people aged 20-78 (75% men, 56% white ethnicity). Overall, median CD4 +  : CD8 + T-cell ratio increased from 0.24 at baseline to 0.77 at year 5 and 0.88 at year 10. Ratios increased among all age groups in unadjusted and adjusted models but increased less among older ages (baseline ages 60-69 and 70-79). Median ratios at year 5 were 0.85, 0.80, 0.72, 0.76, 0.6, and 0.44, respectively, among people aged 20-29, 30-39, 40-49, 50-59, 60-69 and 70-79 years at baseline.

CONCLUSION

In a virally suppressed London population, age had a substantial impact on CD4 +  : CD8 + ratio recovery, especially for those starting ART after age 60 years. Results may indicate the level of CD4 +  : CD8 + ratio recovery possible in an HIV-positive, virally suppressed, aging population.

Pulmonary Function in People Living With Human Immunodeficiency Virus: A Meta-Analysis

BACKGROUND

HIV can infect bronchial epithelial cells rendering individuals susceptible to lung damage. Our objective was to determine the effects of human immunodeficiency virus (HIV) infection on pulmonary function tests.

METHODS

We performed a meta-analysis after conducting a literature search in PubMed, Embase, Cochrane Library and Virtual Health Library databases from inception to December 31st, 2022. We employed the inverse variance method with a random effects model to calculate the effect estimate as the mean difference (MD) and 95% confidence interval (CI). We calculated the heterogeneity with the I2 statistic and performed a meta-regression analysis by age, sex, smoking, CD4 T-cells count and antiretroviral therapy. We also conducted a sensitivity analysis according to the studies' publication date, and excluding the study with the greatest weight in the effect. The PROSPERO registry number was CRD42023401105.

RESULTS

The meta-analysis included 20 studies, with 7621 living with HIV and 7410 control participants. The pooled MD (95%CI) for the predicted percentage of FEV1, FVC and DLCO were -3.12 (-5.17, -1.06); p=0.003, -1.51 (-3.04, 0.02); p=0.05, and -5.26 (-6.64, -3.87); p<0.001, respectively. The pooled MD for FEV1/FVC was -0.01 (-0.02, -0.01); p=0.002. In all cases, there was a considerable heterogeneity. The meta-regression analysis showed that among studies heterogeneity was not explained by patient age, smoking, CD4 T-cells count or antiretroviral therapy.

CONCLUSION

Pulmonary function tests are impaired in people living with HIV, independently of age, smoking, CD4 T-cells count, and geographical region.

Factors influencing left ventricular diastolic dysfunction on echocardiography of people living with HIV in Kunming, China

BACKGROUND

The widespread use of antiretroviral therapy has prolonged the survival of people living with HIV (PLWH). Among these patients, co-existing cardiovascular diseases, particularly left ventricular diastolic dysfunction (LVDD), are receiving increasing attention.

METHODS

We recruited 386 patients in the PLWH group and 386 sex- and age (± 3 years)-matched individuals in the HIV-negative group, and used logistic regression to determine the risk factors of LVDD.

RESULTS

Compared to the HIV-negative group, PLWH had a significantly higher prevalence of smoking (p < .001), alcohol consumption (p < .001), hypertension (p = .002), diabetes (p = .020), and hyperlipidemia (p < .001) and a lower prevalence of body mass index (BMI) ≥ 24.0 kg/m2 (p < .001). The prevalence of LVDD on echocardiography was significantly higher in PLWH than in the HIV-negative group (25.9% vs 16.1%, p = .001). The multivariate analysis showed that non-youth (OR = 8.666; 95%CI = 4.310-17.459; p < .001), BMI ≥ 24.0 kg/m2 (OR = 1.992; 95% CI = 1.007-3.939; p = .048), hypertension (OR = 1.888; 95% CI = 1.044-3.415; p = .036), hyperlipidemia (OR = 1.911; 95% CI = 1.068-3.418; p = .029), and HIV infection (OR = 2.003; 95%CI = 1.341-2.992; p = .001) were risk factors for LVDD.

CONCLUSION

The rate of echocardiographic abnormalities was higher in PLWH. LVDD was associated with non-youth, BMI ≥ 24.0 kg/m2, hypertension, hyperlipidemia, and living with HIV.

Human Immunodeficiency Virus as a Risk Factor for Cardiovascular Disease

The developments in HIV treatments have increased the life expectancy of people living with HIV (PLWH), a situation that makes cardiovascular disease (CVD) in that population as relevant as ever. PLWH are at increased risk of CVD, and our understanding of the underlying mechanisms is continually increasing. HIV infection is associated with elevated levels of multiple proinflammatory molecules, including IL-6, IL-1β, VCAM-1, ICAM-1, TNF-α, TGF-β, osteopontin, sCD14, hs-CRP, and D-dimer. Other currently examined mechanisms include CD4 + lymphocyte depletion, increased intestinal permeability, microbial translocation, and altered cholesterol metabolism. Antiretroviral therapy (ART) leads to decreases in the concentrations of the majority of proinflammatory molecules, although most remain higher than in the general population. Moreover, adverse effects of ART also play an important role in increased CVD risk, especially in the era of rapid advancement of new therapeutical options. Nevertheless, it is currently believed that HIV plays a more significant role in the development of metabolic syndromes than treatment-associated factors. PLWH being more prone to develop CVD is also due to the higher prevalence of smoking and chronic coinfections with viruses such as HCV and HBV. For these reasons, it is crucial to consider HIV a possible causal factor in CVD occurrence, especially among young patients or individuals without common CVD risk factors.

Changes in Quality of life Outcomes of Patients with HIV/AIDS Under a Theory-based Mobile Health Intervention

This study examined the effectiveness of a theory-based mHealth intervention on the quality of life (QOL) of people living with HIV. A randomized controlled trial was performed at two outpatient clinics in Hanoi, Vietnam. There were 428 patients with HIV/AIDs in selected clinics and were divided into the intervention arm (receiving HIV-assisted smartphone application and usual care) and the control arm (receiving only usual care). The WHOQOLHIV-BREF instrument was utilized to measure QOL. An intention-to-treat approach using Generalized Linear Mixed Model analysis was performed. The trial showed significant improvements in Physical health, Psychological health, and Level of Dependence among patients in the intervention arm compared to the control arm. However, the Environment and Spirituality/Personal beliefs improvements would require additional interventions, both individual, organizational, or governmental. This study explored the utility of a smartphone mobile application for individuals with HIV, and how the resultant application could improve the overall QOL.

Pulmonary Function and Quality of Life in Aging Men With and Without HIV from the Multicenter AIDS Cohort Study

People living with HIV have greater pulmonary function impairments and decreased health-related quality of life (HRQoL) compared to uninfected peers. We examined whether pulmonary impairment was associated with HRQoL or respiratory health status. Using Multicenter AIDS Cohort Study data (2017-2019), associations between outcomes [HRQoL (36-Item Short Form Survey) and respiratory health status (St. George's Respiratory Questionnaire)] with pulmonary impairment [diffusing capacity for carbon monoxide (DLCO) and forced expiratory volume in 1 s (FEV1), defined as <80% predicted for both] were examined. Adjusted analyses utilized linear and zero-inflated beta regression, the latter summarized by odds ratio (OR) and quotient ratios (QRs). We also considered whether the subset of adjustment variables age, HIV serostatus, or smoking modified the relationships examined. Of 1048 men, 55% had HIV, with median age 57 [interquartile range (IQR) = 48, 64] years and 1.2 (IQR = 0, 18.1) smoking pack-years. Impaired DLCO, but not impaired FEV1, was significantly associated with lower physical HRQoL [-2.71 (-4.09, -1.33); -1.46 (-3.45, 0.54), respectively]. Pulmonary impairment was associated with higher odds of any St. George's Respiratory Questionnaire (SGRQ) (total score) limitation [DLCO OR = 1.53 (1.15, 2.04); FEV1 OR = 2.48 (1.16, 5.30)] and was elevated in individuals with more severe SGRQ limitations [DLCO QR = 1.13 (0.94, 1.36); FEV1 QR = 1.27 (0.98, 1.64)]. HIV did not modify any associations examined. Age modified the DLCO and any respiratory limitation (SGRQ symptom score) association for every 10 mL CO/min/mmHg decrease in DLCO [age 30 OR = 1.03 (0.51, 2.08); age 50 OR = 1.85 (1.27, 3.85); and age 70 OR = 3.45 (2.00, 5.88)]. Similarly, age modified the DLCO and any respiratory limitation (SGRQ total score) association. FEV1 associations with SGRQ and HRQoL scores were similar across all ages. Impaired pulmonary function was associated with lower HRQoL and greater respiratory impairments. Future studies can determine if interventions aimed at preserving pulmonary function are effective in improving HRQoL and respiratory health among aging men with and without HIV.

COPD in People with HIV: Epidemiology, Pathogenesis, Management, and Prevention Strategies

Chronic obstructive pulmonary disease (COPD) is a progressive respiratory disorder characterized by airflow limitation and persistent respiratory symptoms. People with HIV (PWH) are particularly vulnerable to COPD development; PWH have demonstrated both higher rates of COPD and an earlier and more rapid decline in lung function than their seronegative counterparts, even after accounting for differences in cigarette smoking. Factors contributing to this HIV-associated difference include chronic immune activation and inflammation, accelerated aging, a predilection for pulmonary infections, alterations in the lung microbiome, and the interplay between HIV and inhalational toxins. In this review, we discuss what is known about the epidemiology and pathobiology of COPD among PWH and outline screening, diagnostic, prevention, and treatment strategies.

The Relationship Between Posttraumatic Stress Disorder and Alcohol Misuse and Smoking Among Aging Men Who Have Sex With Men: No Evidence of Exercise or Volunteering Impact

OBJECTIVES

To determine if the association between posttraumatic stress disorder (PTSD) and substance use (alcohol misuse or smoking tobacco) is mediated/moderated by exercise or volunteering among aging (≥40 years) men who have sex with men (MSM), and if this mediation/moderation differs by HIV serostatus.

METHODS

Multicenter AIDS Cohort Study data were used. Three datasets with PTSD measured during different time periods (10/1/2017-3/31/2018, 898 men; 4/1/2018-9/30/2018, 890 men; 10/1/2018-3/31/2019, 895 men) were analyzed. Longitudinal mediation analyses estimated the mediation effect of exercise and volunteering on the outcomes.

RESULTS

Nine percent of MSM had evidence of PTSD. There was no statistically significant mediation effect of exercise or volunteering regardless of substance use outcome. The odds of smoking at a future visit among MSM with PTSD were approximately double those of MSM without PTSD. Results did not differ by HIV serostatus.

DISCUSSION

There is a particular need for effective smoking cessation interventions for aging MSM with PTSD.

Tobacco Smoking and Pack-Years Are Associated With Frailty Among People With HIV

BACKGROUND

Tobacco smoking increases frailty risk among the general population and is common among people with HIV (PWH) who experience higher rates of frailty at younger ages than the general population.

METHODS

We identified 8608 PWH across 6 Centers for AIDS Research Network of Integrated Clinical Systems sites who completed ≥2 patient-reported outcome assessments, including a frailty phenotype measuring unintentional weight loss, poor mobility, fatigue, and inactivity, and scored 0-4. Smoking was measured as baseline pack-years and time-updated never, former, or current use with cigarettes/day. We used Cox models to associate smoking with risk of incident frailty (score ≥3) and deterioration (frailty score increase by ≥2 points), adjusted for demographics, antiretroviral medication, and time-updated CD4 count.

RESULTS

The mean follow-up of PWH was 5.3 years (median: 5.0), the mean age at baseline was 45 years, 15% were female, and 52% were non-White. At baseline, 60% reported current or former smoking. Current (HR: 1.79; 95% confidence interval: 1.54 to 2.08) and former (HR: 1.31; 95% confidence interval: 1.12 to 1.53) smoking were associated with higher incident frailty risk, as were higher pack-years. Current smoking (among younger PWH) and pack-years, but not former smoking, were associated with higher risk of deterioration.

CONCLUSIONS

Among PWH, smoking status and duration are associated with incident and worsening frailty.

Syndemic trajectories of heavy drinking, smoking, and depressive symptoms are associated with mortality in women living with HIV in the United States from 1994 to 2017

BACKGROUND

Heavy drinking, smoking, and depression are common among people with HIV. Little is known about the co-occurring, synergistic effect of having two or more of these conditions long-term -a sustained syndemic - on mortality among women with HIV (WWH).

METHODS

Data from 3282 WWH of the Women's Interagency HIV Study from 1994 to 2017 were utilized. National Death Index review identified cause of death (n=616). Sustained syndemic phenotypes were based on membership in high-risk groups defined by group-based trajectory models of repeated self-reported alcohol use, smoking, and depressive symptoms and their co-occurrence. Cox proportional hazard models estimated associations of sustained syndemic phenotypes with all-cause, non-AIDS, and non-overdose mortality, adjusting for age, race/ethnicity, education, enrollment wave, illicit drug use, and time-varying HIV viral load and CD4+ T-cell count.

RESULTS

WWH were 58% Black and 26% Hispanic, with a mean baseline age of 36.7 years. Syndemic phenotypes included zero (45%, n=1463), heavy drinking only (1%, n=35), smoking only (28%, n=928), depressive symptoms only (9%, n=282), and 2+ trajectories (17%, n=574). Compared to zero trajectories, having 2+ trajectories was associated with 3.93 times greater all-cause mortality risk (95% CI 3.07, 5.04) after controlling for confounders and each high-risk trajectory alone. These findings persisted in sensitivity analyses, removing AIDS- and overdose-related mortalities.

CONCLUSIONS

Clustering of 2+ conditions of heavy drinking, smoking, and depression affected nearly one in five WWH and was associated with higher mortality than zero or one condition. Our findings underscore the need for coordinated screening and parsimonious treatment strategies for these co-occurring conditions.

Prevalence and Correlates of Cardiovascular, Pulmonary, Cancer, and Mental Health Comorbidities Among Adults With HIV Who Smoke

ABSTRACT

Using data from the D.C. Cohort Longitudinal HIV Study, we examined (a) diagnosed mental health and (b) cardiovascular, pulmonary, or cancer (CPC) comorbidity among adults with HIV who smoked. Among 8,581 adults, 4,273 (50%) smoked; 49% of smokers had mental health, and 13% of smokers had a CPC comorbidity. Among smokers, non-Hispanic Black participants had a lower risk for mental health (prevalence ratio [PR]: 0.69; 95% confidence interval [CI] [0.62-0.76]) but a higher risk for CPC (PR: 1.17; 95% CI [0.84-1.62]) comorbidity. Male participants had a lower risk for mental health (PR: 0.88; 95% CI [0.81-0.94]) and CPC (PR: 0.68; 95% CI [0.57-0.81]) comorbidity. All metrics of socioeconomic status were associated with a mental health comorbidity, but only housing status was associated with a CPC comorbidity. We did not find any association with substance use. Gender, socioeconomic factors, and race/ethnicity should inform clinical care and the development of smoking cessation strategies for this population.

Associations between alcohol and cigarette use and type 1 and 2 myocardial infarction among people with HIV

OBJECTIVES

People with HIV have a higher risk of myocardial infarction (MI) than the general population, with a greater proportion of type 2 MI (T2MI) due to oxygen demand-supply mismatch compared with type 1 (T1MI) resulting from atherothrombotic plaque disruption. People living with HIV report a greater prevalence of cigarette and alcohol use than do the general population. Alcohol use and smoking as risk factors for MI by type are not well studied among people living with HIV. We examined longitudinal associations between smoking and alcohol use patterns and MI by type among people living with HIV.

DESIGN AND METHODS

Using longitudinal data from the Centers for AIDS Research Network of Integrated Clinical Systems cohort, we conducted time-updated Cox proportional hazards models to determine the impact of smoking and alcohol consumption on adjudicated T1MI and T2MI.

RESULTS

Among 13 506 people living with HIV, with a median 4 years of follow-up, we observed 177 T1MI and 141 T2MI. Current smoking was associated with a 60% increase in risk of both T1MI and T2MI. In addition, every cigarette smoked per day was associated with a 4% increase in risk of T1MI, with a suggestive, but not significant, 2% increase for T2MI. Cigarette use had a greater impact on T1MI for men than for women and on T2MI for women than for men. Increasing alcohol use was associated with a lower risk of T1MI but not T2MI. Frequency of heavy episodic alcohol use was not associated with MI.

CONCLUSIONS

Our findings reinforce the prioritization of smoking reduction, even without cessation, and cessation among people living with HIV for MI prevention and highlight the different impacts on MI type by gender.

The prevalence of smoking cigarettes among HIV-infected patients after a decade. Single-center analysis

OBJECTIVES

Smoking habit is known to be a risk factor for the development of multiple diseases and conditions, premature death, and worse quality of life. The prevalence of smoking in PLWH is 2-3 times higher than in the general population. The study aimed to evaluate how the prevalence of smoking has changed among PLWH over the past decade.

METHODS

The data of n=204 PLWH hospitalized from November 2018 to November 2019 was analyzed. All patients filled out the survey including age, gender, the number of cigarettes smoked, the number of years as a smoker, and the impact of HIV diagnosis on the number of cigarettes smoked. The data was compared to a similar analysis performed in our department in 2009.

RESULTS

The study showed a decrease in the prevalence of smoking among PLWH over the past decade. In comparison to 2009, a statistically significant (p<0.05) reduction in the number of smoking individuals among ever and never smokers was observed both in males and in females.

CONCLUSIONS

The prevalence of smoking cigarettes among PLWH in our department has significantly decreased since 2009 but remains much higher than in the general population. Smoking cessation interventions provided by HIV care professionals are necessary and should be continued among PLWH.

Robust tobacco smoking self-report in two cohorts: pregnant women or men and women living with or without HIV

Understanding the true burden of tobacco smoking on adverse pregnancy outcomes is critical in generating appropriate interventions to improve outcomes. Self-reporting of human behaviour that is associated with stigma is associated with underreporting in general and may bias the impact of smoking in studies; however, self-reporting is frequently the most practical method of gleaning this information. The objective of this study was to evaluate concordance between self-reported smoking and concentrations of plasma cotinine, a biomarker of smoking, among participants enrolled in two related HIV cohorts. A total of 100 pregnant women (76 living with HIV [LWH] and 24 negative controls) in their third trimester, and 100 men and non-pregnant women (43 LWH and 57 negative controls) were included. Among all participants, 43 pregnant women (49% LWH and 25% negative controls) and 50 men and non-pregnant women (58% LWH and 44% negative controls) were self-reported smokers. The odds of discordance between self-reported smoking and cotinine levels were not significantly different between self-reported smokers and non-smokers, nor between pregnant women and others, but were significantly increased, regardless of self-reported status, among people LWH compared to negative controls. The overall concordance between plasma cotinine and self-reported data among all participants was 94% with a sensitivity and specificity of 90% and 96%, respectively. Taken together, these data demonstrate that participant surveying in a non-judgemental context can lead to accurate and robust self-report smoking data among both persons LWH and not, including in the context of pregnancy.

HIV and chronic lung disease

PURPOSE OF REVIEW

As people living with human immunodeficiency virus (HIV, PLWH) age, aging-related comorbidities have come into focus as major challenges to their overall health. In this review, an in-depth overview of the two most commonly encountered chronic lung diseases in PLWH, chronic obstructive pulmonary disease (COPD) and lung cancer, is provided.

RECENT FINDINGS

The risk for both COPD and lung cancer remains significantly higher in PLWH compared to the HIV-uninfected population, although fortunately rates of lung cancer appear to be declining over the last two decades. Outcomes for PLWH with these conditions, though, continue to be poor with worse survival rates in comparison to the general population. PLWH still face major barriers in accessing care for these conditions, including a higher likelihood of being underdiagnosed with COPD and a lower likelihood of being referred for lung cancer screening or treatment. A lack of evidence for optimal treatment strategies for both COPD and lung cancer still hampers the care of PLWH with these conditions.

SUMMARY

COPD and lung cancer represent substantial burdens of disease in PLWH. Improved access to standard-of-care screening and treatment and greater investigation into therapeutic responses specifically in this population are recommended.

State Variation in Squamous Cell Carcinoma of the Anus Incidence and Mortality, and Association With HIV/AIDS and Smoking in the United States

PURPOSE

Squamous cell carcinoma of the anus (SCCA) incidence and mortality rates are rising in the United States. Understanding state-level incidence and mortality patterns and associations with smoking and AIDS prevalence (key risk factors) could help unravel disparities and provide etiologic clues.

METHODS

Using the US Cancer Statistics and the National Center for Health Statistics data sets, we estimated state-level SCCA incidence and mortality rates. Rate ratios (RRs) were calculated to compare incidence and mortality in 2014-2018 versus 2001-2005. The correlations between SCCA incidence with current smoking (from the Behavioral Risk Factor Surveillance System) and AIDS (from the HIV Surveillance system) prevalence were evaluated using Spearman's rank correlation coefficient.

RESULTS

Nationally, SCCA incidence and mortality rates (per 100,000) increased among men (incidence, 2.29-3.36, mortality, 0.46-0.74) and women (incidence, 3.88-6.30, mortality, 0.65-1.02) age ≥ 50 years, but decreased among men age < 50 years and were stable among similar-aged women. In state-level analysis, a marked increase in incidence (≥ 1.5-fold for men and ≥ two-fold for women) and mortality (≥ two-fold) for persons age ≥ 50 years was largely concentrated in the Midwestern and Southeastern states. State-level SCCA incidence rates in recent years (2014-2018) among men were correlated (r = 0.47, P < .001) with state-level AIDS prevalence patterns. For women, a correlation was observed between state-level SCCA incidence rates and smoking prevalence (r = 0.49, P < .001).

CONCLUSION

During 2001-2005 to 2014-2018, SCCA incidence and mortality nearly doubled among men and women age ≥ 50 years living in Midwest and Southeast. State variation in AIDS and smoking patterns may explain variation in SCCA incidence. Improved and targeted prevention is needed to combat the rise in SCCA incidence and mitigate magnifying geographic disparities.

Factors Associated with Periodontitis in Patients with and without HIV

Purpose

The aim of this study was to compare clinical periodontal conditions in HIV-positive people on HAART with an HIV-negative group, in addition to investigating factors associated with periodontitis in the entire sample.

Methods

This was a cross-sectional study. Data were collected by oral clinical examination for the diagnosis of periodontitis, review of medical records, and application of a questionnaire containing personal data, deleterious habits, and oral hygiene habits for the other variables. The results were analyzed by Pearson's χ ² test and Student's t-test. A logistic regression model was constructed for the multivariate analysis and periodontitis was defined as a dependent variable. The analysis was performed on the entire sample (HIV+ and HIV-) and also on the group consisting of only people living with HIV.

Results

Individuals older than 43 years old and with HIV were more likely to develop moderate and severe periodontitis (47.80 and 4.84 times, respectively). When analyzing only HIV+, in addition to age (OR = 2.795; CI = 1.080-7.233), the use of nonnucleoside reverse transcriptase inhibitors (NNRTIs) (OR = 2.841; CI = 1.135-7.112) was also associated with moderate and severe periodontitis.

Conclusion

It was possible to observe a higher prevalence of periodontitis among individuals with HIV, showing an association between the virus, advanced age, and moderate or severe periodontitis.

Association of HIV Infection With Cardiovascular Pathology Based on Advanced Cardiovascular Imaging: A Systematic Review

IMPORTANCE

HIV-associated cardiovascular disease is increasing in prevalence, but its mechanisms remain poorly understood.

OBJECTIVE

To systematically review data from advanced cardiovascular imaging studies evaluating computed tomographic coronary angiography, positron emission tomography (PET), and cardiac magnetic resonance (MR), in people living with HIV compared with uninfected individuals.

DATA SOURCES

Three databases and Google Scholar were searched for studies assessing cardiovascular pathology using computed tomographic coronary angiography, cardiac MR, PET, and HIV from inception to February 11, 2022.

STUDY SELECTION

Two reviewers selected original studies without any restrictions on design, date, or language, investigating HIV and cardiovascular pathology.

DATA EXTRACTION AND SYNTHESIS

One investigator extracted data checked by a second investigator. Prevalence ratios (PRs) and differences in inflammation among people living with HIV and uninfected individuals were qualitatively synthesized in terms of cardiovascular pathology. Study quality was assessed using the National Heart, Lung, and Blood Institute quality assessment tool for observational studies.

MAIN OUTCOMES AND MEASURES

Primary outcomes were computed tomographic coronary angiography-defined moderate to severe (≥50%) coronary stenosis, cardiac MR-defined myocardial fibrosis identified by late gadolinium enhancement, and PET-defined vascular and myocardial target to background ratio. Prevalence of moderate to severe coronary disease, as well as myocardial fibrosis, and PRs compared with uninfected individuals were reported alongside difference in vascular target to background ratio.

RESULTS

Forty-five studies including 5218 people living with HIV (mean age, 48.5 years) and 2414 uninfected individuals (mean age, 49.1 years) were identified. Sixteen studies (n = 5107 participants) evaluated computed tomographic coronary angiography; 16 (n = 1698), cardiac MRs; 10 (n = 681), vascular PET scans; and 3 (n = 146), both computed tomographic coronary angiography and vascular PET scans. No studies originated from low-income countries. Regarding risk of bias, 22% were classified as low; 47% moderate; and 31% high. Prevalence of moderate to severe coronary disease among those with vs without HIV ranged from 0% to 52% and 0% to 27%, respectively, with PRs ranging from 0.33 (95% CI, 0.01-15.90) to 5.19 (95% CI, 1.26-21.42). Prevalence of myocardial fibrosis among those with vs without HIV ranged from 5% to 84% and 0% to 68%, respectively, with PRs ranging from 1.01 (95% CI, 0.85-1.21) to 17.35 (95% CI, 1.10-274.28). Differences in vascular target to background ratio among those with vs without HIV ranged from 0.06 (95% CI, 0.01-0.11) to 0.37 (95% CI, 0.02-0.72).

CONCLUSIONS AND RELEVANCE

In this systematic review of studies of advanced cardiovascular imaging, the estimates of the associations between HIV and cardiovascular pathologies demonstrated large amounts of heterogeneity. The findings provide a summary of the available data but may not be representative of all individuals living with HIV, including those from low-income countries with higher HIV endemicity.

Practices, attitudes, and confidence related to tobacco treatment interventions in HIV clinics: a multisite cross-sectional survey

Tobacco use disorder (TUD) is a major threat to health among people with HIV (PWH), but it is often untreated. Among HIV clinicians and staff, we sought to characterize practices, attitudes, and confidence addressing TUD among PWH to identify potential opportunities to enhance provision of care. Cross-sectional deidentified, web-based surveys were administered from November 4, 2020 through December 15, 2020 in HIV clinics in three health systems in the United States Northeast. Surveys assessed provider characteristics and experience, reported practices addressing tobacco use, and knowledge and attitudes regarding medications for TUD. Chi-square tests or Fisher's exact tests were used to examine differences in responses between clinicians and staff who were prescribers versus nonprescribers and to examine factors associated with frequency of prescribing TUD medications. Among 118 survey respondents (56% prescribers), only 50% reported receiving prior training on brief smoking cessation interventions. Examining reported practices identified gaps in the delivery of TUD care, including counseling patients on the impact of smoking on HIV, knowledge of clinical practice guidelines, and implementation of assessment and brief interventions for smoking. Among prescribers, first-line medications for TUD were infrequently prescribed and concerns about medication side effects and interaction with antiretroviral treatments were associated with low frequency of prescribing. HIV clinicians and staff reported addressable gaps in their knowledge, understanding, and practices related to tobacco treatment. Additional work is needed to identify ways to ensure adequate training for providers to enhance the delivery of TUD treatment in HIV clinic settings.

Weight of Clinical and Social Determinants of Metabolic Syndrome in People Living with HIV

Background. Comorbidities in people living with HIV (PLWH) represent a major clinical challenge today, and metabolic syndrome (MTBS) is one of the most important. Objective. Our objective was to assess the prevalence of MTBS and the role of both clinical/socio-behavioral risk factors for MTBS in a cohort of PLWH. Methods. All PLWH, over 18 years of age, attending all Infectious Disease Units in Calabria Region (Southern Italy) for their routine checks from October 2019-January 2020 were enrolled. MTBS was defined by NCEP-ATP III criteria. Logistic regression analysis was performed to assess factors significantly associated with the main outcome (MTBS). Results. We enrolled 356 PLWH, mostly males (68.5%), with a mean age of 49 years (standard deviation: 12), including 98 subjects with and 258 without MTBS. At logistic regression analysis, a statistically significant association was found between MTBS and alcohol use, osteoporosis, polypharmacy, and a history of AIDS. Conclusions. Identifying and addressing risk factors, including those that are socio-behavioral or lifestyle-related, is crucial to prevent and treat MTBS. Our results suggest the importance of implementing educational/multidimensional interventions to prevent MTBS in PLWH, especially for those with particular risk factors (alcohol abuse, osteoporosis, previous AIDS events, and polypharmacy). Moreover, alcohol consumption or abuse should be routinely investigated in clinical practice.

Cardiovascular risk factors and markers of myocardial injury and inflammation in people living with HIV in Nairobi, Kenya: a pilot cross-sectional study

OBJECTIVES

To determine the prevalence of cardiovascular disease (CVD) risk factors and explore associations with high-sensitivity cardiac troponin I (hscTnI) and high-sensitivity C-reactive protein (hsCRP) in people living with HIV (PLHIV) in Kenya.

DESIGN

Pilot cross-sectional study.

SETTING

Data were collected from community HIV clinics across two sites in Nairobi, Kenya, from July 2019 to May 2020.

PARTICIPANTS

Convenience sample of 200 PLHIV (≥30 years with no prior history of CVD).

OUTCOME MEASURES

Prevalence of cardiovascular risk factors and its association with hsTnI and hsCRP levels.

RESULTS

Across 200 PLHIV (median age 46 years, IQR 38-53; 61% women), the prevalence of hypercholesterolaemia (total cholesterol >6.1 mmol/L) and hypertension were 19% (n=30/199) and 30% (n=60/200), respectively. Smoking and diabetes prevalence was 3% (n=5/200) and 4% (n=7/200). HscTnI was below the limit of quantification (<2.5 ng/L) in 65% (n=109/169). High (>3 mg/L), intermediate (1-3 mg/L) and low (<1 mg/L) hsCRP levels were found in 38% (n=75/198), 33% (n=65/198) and 29% (n=58/198), respectively. Framingham laboratory-based risk scores classified 83% of PLHIV at low risk with 12% and 5% at intermediate and high risk, respectively. Older age (adjusted OR (aOR) per year increase 1.05, 95% CI 1.01 to 1.08) and systolic blood pressure (140-159 mm Hg (aOR 2.96; 95% CI 1.09 to 7.90) and >160 mm Hg (aOR 4.68, 95% CI 1.55 to 14) compared with <140 mm Hg) were associated with hscTnI levels. No associations were observed between hsCRP and CVD risk factors.

CONCLUSION

The majority of PLHIV-using traditional risk estimation systems-have a low estimated CVD risk likely reflecting a younger aged population predominantly consisting of women. Hypertension and hypercholesterolaemia were common while smoking and diabetes rates remained low. While hscTnI values were associated with increasing age and raised blood pressure, no associations between hsCRP levels and traditional cardiovascular risk factors were observed.

Optimizing tobacco treatment delivery for people with HIV: trial protocol for a randomized controlled trial

BACKGROUND

With advances in antiretroviral therapy, people with HIV (PWH) are living longer and are less likely to die from AIDS-related complications. Yet, prior research has shown that smoking is often not addressed in the context of HIV care, and few individuals are offered cessation treatment. Optimizing tobacco treatment delivery for PWH may increase engagement with evidence-based treatments and successful quit attempts.

METHODS

The current study is a type 1 hybrid effectiveness-implementation trial to evaluate the impact of a proactive, opt-out tobacco treatment intervention on cessation outcomes and advance understanding of key barriers and facilitators of implementation processes. A total of 230 PWH who smoke will be recruited from an infectious diseases clinic at an academic medical center and will be randomized to receive (1) treatment as usual (TAU) or (2) Proactive Outreach with Medication Opt-out for Tobacco Treatment Engagement (PrOMOTE). Primary outcomes include: biochemically verified 7-day point prevalence abstinence (PPA) rates, continuous abstinence (Weeks 9-12), and the number of 24-hour quit attempts at the end of study treatment (Week 12). Secondary outcomes include: participant reach (proportion reached out of contact attempts), implementation fidelity (including number of prescriptions written), participant adherence to prescribed pharmacotherapy, acceptability (participant and provider satisfaction with intervention delivery and content), and perceived barriers.

DISCUSSION

This study will examine a novel approach to optimizing tobacco treatment delivery for PWH. Integrating effectiveness and implementation results will help define best practices for engaging PWH with evidence-based tobacco treatment interventions. The intervention is low-cost, has the potential to be highly scalable, and could be translatable to other ambulatory HIV clinic settings.

What problems associated with ageing are seen in a specialist service for older people living with HIV?

OBJECTIVES

By 2030 the majority of the people living with HIV in the United Kingdom will be over the age of 50. HIV services globally must adapt to manage people living with HIV as they age. Currently these services are often designed based on data from the wider population or from the experiences of HIV clinicians. This article aims to help clinicians designing inclusive HIV services by presenting the most common needs identified during the first year of a specialist clinic for older people living with HIV at the Ian Charleson Day Centre, Royal Free Hospital in London, United Kingdom.

METHODS

The records of all thirty-five patients attending the inaugural nine sessions were reviewed.

RESULTS

The median age of attendees was 69 (53-93) with 77% being male, 63% being White, 49% being heterosexual and 97% being virally suppressed respectively. The majority (83%) met the criteria for frailty using the Fried frailty phenotype. Eighteen issues linked to ageing were identified with the most common being affective symptoms (51%), memory loss (37%) and falls (29%).

CONCLUSIONS

Whilst older people living with HIV are a heterogeneous group frailty is common and appears to present earlier. HIV services either need to adapt to meet these additional needs or must support users in transitioning to existing services. We feel that our multidisciplinary model is successful in identifying problems associated with ageing in people living with HIV and could be successfully replicated elsewhere.

Quality of life among people living with HIV in England and the Netherlands: a population-based study

Background

HIV is now considered a chronic condition, and people living with HIV, when treated, have a similar life expectancy as compared to the general population. Consequently, improving and ensuring a good health-related quality of life (HrQoL) among people living with HIV (people living with HIV) is increasingly important and has risen on the global agenda in recent years. A 'fourth 90' as 90% of people with viral load suppression have a good HrQoL should therefore be adopted alongside the other 90-90-90 targets. This study aims to report the progress on HrQoL as the 'fourth 90' and compare against the general population in the Netherlands and England.

Methods

In the Netherlands, individuals attending the HIV outpatient clinic of a tertiary hospital were asked to complete the EQ-5D-5L from June 2016 until December 2018. In England, individuals attending one of 73 HIV outpatient clinics were randomly sampled to complete the Positive Voices survey, which included the EQ-5D-5L, from January to September 2017. HrQoL scores were combined with demographic data and compared to general population data.

Findings

The EQ-5D-5L was filled-out by 895 people living with HIV in the NL and 4,137 in England. HrQoL_utility was 0·85 among Dutch and 0·83 among English people living with HIV. This equated to 98% and 94% of the general population HrQoL_utility in the Netherlands and England, respectively. Of the EQ-5D domains, anxiety/depression was mostly affected, with one-third in Dutch (35%) and almost half (47%) of English people living with HIV reporting symptoms. This was higher compared to their respective general populations (21% NL and 31% England).

Interpretation

Overall, HrQoL_utility for people living with HIV was high in both countries and highly comparable to the general populations Nevertheless, there should be an increased focus on anxiety and depression in the people living with HIV population The EQ-5D-5L proved an easy HrQoL measurement tool and identified areas for improvement by social and behavioural interventions.

Funding

The study received funding (unrestricted grants) from: Gilead sciences, ViiV Healthcare, MSD, and Jansen pharmaceuticals.
