The impact of long-term moderate and heavy alcohol consumption on incident atherosclerosis among persons living with HIV

The Impact of Dietary Diversity, Lifestyle, and Blood Lipids on Carotid Atherosclerosis: A Cross-Sectional Study

Carotid atherosclerosis is a common arterial wall lesion that causes narrowing and occlusion of the arteries and is the basis of cardiovascular events. Dietary habits, lifestyle, and lipid metabolism should be considered integrally in the context of carotid atherosclerosis (CAS). However, this area has been investigated less often in China. To understand the prevalence of CAS in China and the impact of dietary diversity and habits, lifestyle, and lipid metabolism on CAS as well as its predictive factors, a cross-sectional study was performed in two northern and southern Chinese tertiary hospitals from 2017 to 2019. Included participants underwent carotid artery color Doppler ultrasonography, blood lipid examination and dietary evaluation. In total, 11,601 CAS patients and 27,041 individuals without carotid artery lesions were included. The prevalence of CAS was 30.0% in this group. High BMI (OR: 1.685, 95% CI [1.315-2.160]), current (1.148 [1.077-1.224]) or ex-smoking (1.349 [1.190-1.529]), abstinence from alcohol ((1.223 [1.026-1.459]), social engagement (1.122 [1.050-1.198]), hypertension (1.828 [1.718-1.945]), and total cholesterol (1.438 [1.298-1.594]) were risk factors for CAS, while higher dietary diversity according to DDS-2 (0.891 [0.805-0.989]), HDL-C (0.558 [0.487-0.639]), sugar-sweetened beverages (0.734 [0.696-0.774]), and no midnight snack consumption (0.846 [0.792-0.903]) were protective factors. This current study demonstrated that higher dietary diversity was a protective factor against CAS in a healthy population. In addition, current recommendations of healthy lifestyle and dietary habits for preventing CAS should be strengthened. In addition, dietary diversity should concentrate on food attributes and dietary balance, rather than increased quantities.

Contribution of Behavioral Health Factors to Non-AIDS-Related Comorbidities: an Updated Review

PURPOSE OF REVIEW

We summarize recent literature on the contribution of substance use and depression to non-AIDS-related comorbidities. Discussion of recent randomized clinical trials and implementation research to curtail risk attributed to each behavioral health issue is provided.

RECENT FINDINGS

Smoking, unhealthy alcohol use, opioid use, and depression are common among PWH and individually contribute to increased risk for non-AIDS-related comorbidities. The concurrence of these conditions is notable, yet understudied, and provides opportunity for linked-screening and potential treatment of more than one behavioral health factor. Current results from randomized clinical trials are inconsistent. Investigating interventions to reduce the impact of these behavioral health conditions with a focus on implementation into clinical care is important. Non-AIDS-defining cancers, cardiovascular disease, liver disease, and diabetes are leading causes of morbidity in people with HIV. Behavioral health factors including substance use and mental health issues, often co-occurring, likely contribute to the excess risk of non-AIDS-related comorbidities.

Alcohol consumption in relation to carotid subclinical atherosclerosis and its progression: results from a European longitudinal multicentre study

Background/Aim

The association between alcohol consumption and subclinical atherosclerosis is still unclear. Using data from a European multicentre study, we assess subclinical atherosclerosis and its 30-month progression by carotid intima-media thickness (C-IMT) measurements, and correlate this information with self-reported data on alcohol consumption.

Methods

Between 2002–2004, 1772 men and 1931 women aged 54–79 years with at least three risk factors for cardiovascular disease (CVD) were recruited in Italy, France, Netherlands, Sweden, and Finland. Self-reported alcohol consumption, assessed at baseline, was categorized as follows: none (0 g/d), very-low (0 − 5 g/d), low (> 5 to  ≤ 10 g/d), moderate (> 10 to ≤ 20 g/d for women,  > 10 to ≤ 30 g/d for men) and high (> 20 g/d for women, > 30 g/d for men). C-IMT was measured in millimeters at baseline and after 30 months. Measurements consisted of the mean and maximum values of the common carotids (CC), internal carotid artery (ICA), and bifurcations (Bif) and whole carotid tree. We used quantile regression to describe the associations between C-IMT measures and alcohol consumption categories, adjusting for sex, age, physical activity, education, smoking, diet, and latitude.

Results

Adjusted differences between median C-IMT values in different levels of alcohol consumption (vs. very-low) showed that moderate alcohol consumption was associated with lower C-IMT_max[− 0.17(95%CI − 0.32; − 0.02)], and Bif-IMT_mean[− 0.07(95%CI − 0.13; − 0.01)] at baseline and decreasing C-IMT_mean[− 0.006 (95%CI − 0.011; − 0.000)], Bif-IMT_mean[− 0.016(95%CI − 0.027; − 0.005)], ICA-IMT_mean[− 0.009(95% − 0.016; − 0.002)] and ICA-IMT_max[− 0.016(95%: − 0.032; − 0.000)] after 30 months. There was no evidence of departure from linearity in the association between alcohol consumption and C-IMT.

Conclusion

In this European population at high risk of CVD, findings show an inverse relation between moderate alcohol consumption and carotid subclinical atherosclerosis and its 30-month progression, independently of several potential confounders.

HIV and Cardiovascular Disease: Update on Clinical Events, Special Populations, and Novel Biomarkers

PURPOSE OF REVIEW

The objective of this review is to provide an update on the link between HIV infection and cardiovascular disease (CVD). We will focus our review mainly on literature describing clinical CVD events and understudied topics of importance.

RECENT FINDINGS

Heart failure, peripheral artery disease, and stroke are CVD modalities deserving more attention in the context of HIV infection in the highly active antiretroviral therapy era. Incidence data on clinical CVD from HIV populations in low- and middle-income countries are limited. Multisubstance use is common in HIV, but understudied as a moderator or mediator of the association between HIV and CVD. CVD risk assessment in HIV remains challenging, but new research into novel biomarkers may provide further insights. There is also a need for inclusion of non-biologic factors in our attempts to understand, quantify, and predict CVD risk among PLWHA. Significant attention has been paid to generating and testing hypotheses to understand the mechanisms of myocardial infarction in HIV. Similar attention is deserving for heart failure, PAD, stroke, and cardiovascular disease risk in resource-limited settings and among substance users with HIV.

The Impact of Past and Current Alcohol Consumption Patterns on Progression of Carotid Intima-Media Thickness Among Women and Men Living with HIV Infection

BACKGROUND

The relationship between alcohol consumption and atherosclerosis has not been sufficiently examined among people living with HIV (PLWH).

METHODS

We analyzed data from PLWH in the Women's Interagency HIV Study (WIHS; n = 1,164) and the Multicenter AIDS Cohort Study (MACS; n = 387) with no history of cardiovascular disease (CVD). Repeated measures of intima-media thickness of the right common carotid artery (CCA-IMT) were assessed using B-mode ultrasound from 2004 to 2013. Current alcohol consumption was collected at time of CCA-IMT measurement and was categorized according to gender-specific weekly limits. Group-based trajectory models categorized participants into past 10-year consumption patterns (1994 to 2004). Multivariate generalized estimating equations were conducted to assess the association of past and current alcohol use patterns on change in CCA-IMT by cohort, controlling for age, race, cigarette and illicit drug use, probable depression, HIV RNA viral load, antiretroviral therapy exposure, and hepatitis C coinfection.

RESULTS

Among the WIHS, past heavy alcohol consumption was associated with increased CCA-IMT level over time (β = 8.08, CI 0.35, 15.8, p = 0.04), compared to abstinence. Among the MACS, compared to abstinence, all past consumption patterns were associated with increased CCA-IMT over time (past low: β = 15.3, 95% CI 6.46, 24.2, p < 0.001; past moderate: β = 14.3, CI 1.36, 27.2, p = 0.03; past heavy: β = 21.8, CI 4.63, 38.9, p = 0.01). Current heavy consumption was associated with decreased CCA-IMT among the WIHS (β = -11.4, 95% CI -20.2, -2.63, p = 0.01) and MACS (β = -15.4, 95% CI -30.7, -0.13, p = 0.04). No statistically significant time by consumption pattern effects were found.

CONCLUSIONS

In both cohorts, 10-year heavy consumption was associated with statistically significant increases in carotid artery thickness, compared to abstinence. Long-term patterns of drinking at any level above abstinence were particularly significant for increases in IMT among men, with heavy consumption presenting with the greatest increase. Our results suggest a potentially different window of risk among past and current heavy drinkers. Further studies are needed to determine whether alcohol consumption level is associated with intermediate measures of atherosclerosis. Alcohol screening and interventions to reduce heavy consumption may benefit PLWH who are at risk of CVD.
