Associations between Alcohol Consumption and HDL Subspecies Defined by ApoC3, ApoE and ApoJ: the Cardiovascular Health Study

Alcohol consumption increases circulating high-density lipoprotein cholesterol (HDL-C), but HDL protein cargo may better reflect HDL function. This study examined the associations between alcohol intake and HDL subspecies containing or lacking apoC3, apoE, and apoJ in a well-phenotyped cohort. We performed a cross-sectional analysis of 2092 Cardiovascular Health Study participants aged 70 or older with HDL subspecies measured in stored specimens from 1998 to 1999. Associations between alcohol intake and apoA1 defined HDL subspecies lacking or containing apoC3, apoE, and apoJ, and circulating levels of total apoA1, apoC3, apoE, and apoJ were examined. HDL subspecies lacking and containing apoC3, apoE, and apoJ were all positively associated with alcohol intake, with ∼1% per additional drink per week or ∼7% per additional drink per day (subspecies without the apolipoproteins, P ≤ 2 × 10^-9, subspecies with the apolipoproteins, P ≤ 3 × 10^-5). Total apoA1 was also directly associated with alcohol consumption, with a 1% increase per additional drink per week (P = 1 × 10^-14). Total apoC3 blood levels were 0.5% higher per additional drink per week (P = 0.01), but the association was driven by a few heavily drinking men. Alcohol intake was positively associated with HDL subspecies lacking and containing apoC3, apoE, or apoJ, and with total plasma apoA1. ApoC3 was directly, albeit not as robustly associated with alcohol intake. HDL protein cargo is crucial for its anti-atherosclerotic functions, but it remains to be determined whether HDL subspecies play a role in the putative association between limited alcohol intake and lower risk of coronary heart disease.

Patient-Reported Outcomes and Health-Related Quality of Life in People Living With Ileostomies: A Population-Based, Cross-Sectional Study

BACKGROUND

The impact of a stoma on long-term health-related quality of life in people living with ileostomies is not clear.

OBJECTIVE

This study aimed to describe important patient-reported outcomes and health-related quality of life in people with ileostomies.

DESIGN

This is a population-based, cross-sectional study. Patients were invited to answer questionnaires estimating stoma-specific and generic health-related quality of life (EQ-5D-5L and the Major Depression Inventory). Danish norms were retrieved from reference literature.

SETTINGS

This study was conducted at the major stoma clinic at Aarhus University Hospital, Denmark.

PATIENTS

We invited all patients with ileostomies who were in contact with the clinic between 2012 and 2017.

MAIN OUTCOME MEASURES

The primary outcomes measured were patient-reported outcomes specific to people with ileostomies.

RESULTS

Of 621 identified patients (50% women), 412 (67%) responded to the survey. Among the responders, 178 (43%) reported that they still had an ileostomy at the time of the survey and were included in the analysis. Fatigue was frequent; 68% (95% CI 60%-75%) reported being tired and 26% (95% CI 20%-33%) answered that they were "always tired," whereas 43% (95% CI 36%-51%) lacked energy, 62% (95% CI 54%-69%) reported poor sleep, and 59% (95% CI 52%-66%) needed to rest during the day. Fifty-six percent (95% CI 48%-63%) needed to know the immediate location of the nearest toilet, and 58% (95% CI 51%-66%) felt sexually unattractive because of their ileostomy. Health-related quality of life measured with generic questions indicated 0.124 points lower health-related quality of life than the Danish norm ( p < 0.001), and 18% (95% CI 13%-25%) scored above the threshold for depression, which is 2.6 times higher than the background population (7%, 95% CI 6%-9%; p < 0.001).

LIMITATIONS

This study was limited by potential selection bias, and all participants did not answer all items.

CONCLUSIONS

Fatigue and low health-related quality of life is common in people living with ileostomies. Addressing fatigue and stoma-specific challenges in patients with an ileostomy is warranted. See Video Abstract at http://links.lww.com/DCR/B803 .

Moderate alcohol consumption and lipoprotein subfractions: a systematic review of intervention and observational studies

CONTEXT

Moderate alcohol consumption is associated with decreased risk of cardiovascular disease (CVD) and improvement in cardiovascular risk markers, including lipoproteins and lipoprotein subfractions.

OBJECTIVE

To systematically review the relationship between moderate alcohol intake, lipoprotein subfractions, and related mechanisms.

DATA SOURCES

Following PRISMA, all human and ex vivo studies with an alcohol intake up to 60 g/d were included from 8 databases.

DATA EXTRACTION

A total of 17 478 studies were screened, and data were extracted from 37 intervention and 77 observational studies.

RESULTS

Alcohol intake was positively associated with all HDL subfractions. A few studies found lower levels of small LDLs, increased average LDL particle size, and nonlinear relationships to apolipoprotein B-containing lipoproteins. Cholesterol efflux capacity and paraoxonase activity were consistently increased. Several studies had unclear or high risk of bias, and heterogeneous laboratory methods restricted comparability between studies.

CONCLUSIONS

Up to 60 g/d alcohol can cause changes in lipoprotein subfractions and related mechanisms that could influence cardiovascular health.

The Moderate Alcohol and Cardiovascular Health Trial (MACH15): Design and methods for a randomized trial of moderate alcohol consumption and cardiometabolic risk

BACKGROUND

Observational studies have documented lower risks of coronary heart disease and diabetes among moderate alcohol consumers relative to abstainers, but only a randomized clinical trial can provide conclusive evidence for or against these associations.

AIM

The purpose of this study was to describe the rationale and design of the Moderate Alcohol and Cardiovascular Health Trial, aimed to assess the cardiometabolic effects of one alcoholic drink daily over an average of six years among adults 50 years or older.

METHODS

This multicenter, parallel-arm randomized trial was designed to compare the effects of one standard serving (∼11-15 g) daily of a preferred alcoholic beverage to abstention. The trial aimed to enroll 7800 people at high risk of cardiovascular disease. The primary composite endpoint comprised time to the first occurrence of non-fatal myocardial infarction, non-fatal ischemic stroke, hospitalized angina, coronary/carotid revascularization, or total mortality. The trial was designed to provide >80% power to detect a 15% reduction in the risk of the primary outcome. Secondary outcomes included diabetes. Adverse effects of special interest included injuries, congestive heart failure, alcohol use disorders, and cancer.

RESULTS

We describe the design, governance, masking issues, and data handling. In three months of field center activity until termination by the funder, the trial randomized 32 participants, successfully screened another 70, and identified ∼400 additional interested individuals.

CONCLUSIONS

We describe a feasible design for a long-term randomized trial of moderate alcohol consumption. Such a study will provide the highest level of evidence for the effects of moderate alcohol consumption on cardiovascular disease and diabetes, and will directly inform clinical and public health guidelines.
