Abstract
BACKGROUND Monocyte dysfunction may persist during antiretroviral therapy (ART). METHODS Frozen peripheral blood mononuclear cells of 30 human immunodeficiency virus (HIV)-infected ART-treated adults with sustained viral suppression and CD4 counts ≥500 cells/µL were consecutively analyzed for monocyte phenotypes and function. RESULTS Nonclassical monocytes (CD14+, CD16++), interleukin (IL)-1β production, and expression of CD40 and CD86 were lower among ART-treated HIV-infected adults relative to age-matched HIV-negative adults (P = .01, P = .01, and P = .02, respectively). Intestinal fatty acid-binding protein, IL6, and soluble CD14 were higher among HIV-infected adults relative to HIV-negative adults (P = .0002, P = .04, and P = .0017, respectively). CONCLUSIONS Further investigation is required to understand drivers of persistent monocyte activation and dysfunction.

Association of High-Sensitivity Troponin with Cardiac CT Angiography Evidence of Myocardial and Coronary Disease in a Primary Prevention Cohort of Men: Results from MACS. J Appl Lab Med 2019; 4:355-369. [PMID: 31659073 PMCID: PMC7085121 DOI: 10.1373/jalm.2018.028860] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/13/2018] [Accepted: 03/12/2019] [Indexed: 12/27/2022]
Abstract
BACKGROUND High-sensitivity cardiac troponin (hs-cTn) elevations are associated with incident cardiovascular disease events in primary prevention samples. However, the mechanisms underlying this association remain unclear. METHODS We studied 458 men without known cardiovascular disease who participated in the cardiovascular disease substudy of the Multicenter AIDS Cohort Study and had cardiac CT angiography. We used multivariable linear and logistic regression models to examine the cross-sectional associations between coronary artery stenosis, coronary artery plaque, indexed left ventricular mass (LVMi), and the outcome of hs-cTnI. We also evaluated the associations between HIV serostatus or use of highly active antiretroviral therapy (HAART) and hs-cTnI. RESULTS The mean age was 54 years, 54% were white, and 61% were HIV infected. In multivariable-adjusted logistic models, comparing the highest quartile of LVMi with the lowest quartile, the odds ratio (OR) of hs-cTnI ≥75th percentile was 2.59 (95% CI, 1.20-5.75). There was no significant association between coronary stenosis severity or plaque type and hs-cTnI in linear models; however, in logistic regression models, coronary artery stenosis ≥70% (8% of sample) was marginally associated with a higher likelihood (OR, 2.75 [95% CI, 1.03, 7.27]) of having hs-cTnI ≥75th percentile. There were no associations between HIV serostatus or HAART use and hs-cTnI in either linear or logistic models. CONCLUSION Among primary prevention men with or at risk for HIV, hs-cTnI concentrations were strongly associated with LVMi but were not associated with HIV infection or treatment status or with coronary plaque type or stenosis until the extremes of severity (≥70% stenosis).

Clinician's Guide to the Updated ABCs of Cardiovascular Disease Prevention: A Review Part 1. Am J Med 2019; 132:e569-e580. [PMID: 30710541 DOI: 10.1016/j.amjmed.2019.01.016] [Citation(s) in RCA: 13] [Impact Index Per Article: 2.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/12/2019] [Revised: 01/23/2019] [Accepted: 01/23/2019] [Indexed: 01/17/2023]
Abstract
Efforts to better control risk factors for cardiovascular disease and prevent the development of subsequent events are crucial to maintaining healthy populations. In today's busy practice environment and with the overwhelming pace of new research findings, ensuring appropriate emphasis and implementation of evidence-based preventive cardiovascular care can be challenging. The ABCDEF approach to cardiovascular disease prevention is intended to improve dissemination of contemporary best practices and facilitate the implementation of comprehensive preventive strategies for clinicians. This review serves as a succinct yet authoritative overview for internists and subspecialty cardiologists not otherwise focused on cardiovascular prevention. The goal of this 2-part series is to compile a state-of-the-art list of elements central to both primary and secondary prevention of cardiovascular disease, using an ABCDEF checklist, with particular focus on recent society guideline updates. In Part 1 we highlight developments in cardiovascular risk assessment tools, summarize important recent aspirin trials, discuss prevention considerations in atrial fibrillation, and review guidelines for blood pressure categorization, goals, and therapy.

The prognostic value of interleukin 6 in multiple chronic diseases and all-cause death: The Multi-Ethnic Study of Atherosclerosis (MESA). Atherosclerosis 2018; 278:217-225. [PMID: 30312930 DOI: 10.1016/j.atherosclerosis.2018.09.034] [Citation(s) in RCA: 25] [Impact Index Per Article: 4.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/03/2018] [Revised: 09/12/2018] [Accepted: 09/25/2018] [Indexed: 12/20/2022]
Abstract
BACKGROUND AND AIMS We aimed to evaluate the associations and prognostic value of interleukin-6 (IL6) for the prediction of atherosclerotic cardiovascular disease (ASCVD) events, heart failure (HF), and other chronic diseases in a large, multi-ethnic, contemporary population. METHODS We included 6617 participants from the Multi-Ethnic Study of Atherosclerosis (5640 non-users, 977 users of statins at baseline). Main outcomes were hard ASCVD events and HF; secondary outcomes included all-cause death, atrial fibrillation, venous thromboembolism and cancer. RESULTS Median follow-up was 13.2 years. Strong associations were observed in Cox regression analyses between higher IL6 levels and ASCVD events, HF, and mortality, particularly among statins users. In the latter, associations remained strong after adjusting for traditional risk factors and other inflammation biomarkers (e.g., risk factor, hsCRP-adjusted hazard ratio for incident HF comparing 3rd vs. 1st IL6 tertiles: 3.55, 95% CI 1.23-10.27). Although IL6 did not improve CHD prediction beyond traditional risk factors, among statin users it improved the prediction of stroke (improvement in the C statistic +0.018), incident HF (+0.028, the largest C statistic increase across all study outcomes), and all-cause death (+0.017). CONCLUSIONS IL6 is strongly and independently associated with ASCVD events, HF, and all-cause mortality, particularly among statin users. Although the prognostic value of IL6 is limited for the prediction of CHD events, it may have a role for the prediction of stroke, HF and all-cause death in asymptomatic statin users. Larger studies are needed to replicate these findings.
