Abstract
BACKGROUND While smokeless tobacco (ST) causes oral cancer and is associated with cardiovascular diseases, less is known about how its effects differ from other tobacco use. Biomarkers of potential harm (BOPH) can measure short-term health effects such as inflammation and oxidative stress. METHODS We compared BOPH concentrations [IL6, high-sensitivity C-reactive protein, fibrinogen, soluble intercellular adhesion molecule-1 (sICAM-1), and F2-isoprostane] across 3,460 adults in wave 1 of the Population Assessment of Tobacco and Health study (2013-2014) by tobacco use groups: primary ST users (current exclusive ST use among never smokers), secondary ST users (current exclusive ST use among former smokers), exclusive cigarette smokers, dual users of ST and cigarettes, former smokers, and never tobacco users. We estimated geometric mean ratios using never tobacco users, cigarette smokers, and former smokers as referents, adjusting for demographic and health conditions, creatinine (for F2-isoprostane), and pack-years in smoker referent models. RESULTS BOPH levels among primary ST users were similar to both never tobacco users and former smokers. Most BOPH levels were lower among ST users compared with current smokers. Compared with never tobacco users, dual users had significantly higher sICAM-1, IL6, and F2-isoprostane. However, compared with smokers, dual users had similar biomarker levels. Former smokers and secondary ST users had similar levels of all five biomarkers. CONCLUSIONS ST users have lower levels of inflammatory and oxidative stress biomarkers than smokers. IMPACT ST use alone and in combination with smoking may result in different levels of inflammatory and oxidative stress levels.

Evaluation of systemic inflammatory and thrombotic markers of cardiovascular risk among young Indian oral tobacco users. Indian Heart J 2020; 72:389-393. [PMID: 33189199 PMCID: PMC7670266 DOI: 10.1016/j.ihj.2020.08.005] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/10/2020] [Revised: 07/11/2020] [Accepted: 08/03/2020] [Indexed: 12/23/2022] Open
Abstract
Background While the pro-inflammatory and pro-coagulant effects of cigarette smoking have been well described, the effect of smokeless tobacco (ST) on inflammatory and coagulation markers is still not clear. The study aimed to evaluate impact of smokeless tobacco use on systemic markers of inflammation [(TLC), neutrophil-lymphocyte ratio (NLR) (ESR), interleukin (IL) IL-1β, IL-6 and tumor necrosis factor alpha (TNFα)] and hypercoagulable state [fibrinogen and d-dimer] leading to increased cardiovascular risk in ST users as compared to non-users. Methods 150 healthy young adults using oral tobacco products for at least 1 year were included in the case group and 50 age-matched non-consumers as controls. Subjects with any known chronic illness or comorbidity were excluded from the study. Blood samples were tested for TLC, NLR, ESR, IL-1β, IL-6, TNFα, fibrinogen and d-dimer. Statistical analysis was done using SPSS 17.0 software. Results The baseline clinical and cardio-metabolic characteristics were comparable between the two groups. ST users had significantly elevated serum IL-6 [59.29 ± 124.69 pg/mL (n = 149) vs 8.21 ± 27.27 pg/mL (n = 47), p-value = 0.005], TNFα [77.18 ± 236.10 pg/mL (n = 149) vs 8.32 ± 9.36 pg/mL (n = 47), p-value = 0.041], fibrinogen [310.53 ± 129.05 mg/dL (n = 143) vs 282.82 ± 65.23 mg/dL (n = 42), p-value = 0.045] and d-dimer [0.28 ± 0.42 mg/L (n = 144) vs 0.17 ± 0.09 mg/L (n = 45), p-value = 0.043] levels as compared to non-users. Serum TLC, NLR, ESR and IL-1β remained unchanged in ST users and were similar to that of controls. Conclusions Chronic use of ST is associated with systemic inflammation and coagulation, which may increase the risk of athero-thrombotic cardiovascular events among ST users.

Abstract
Introduction Since 2009, the United States (US) Food and Drug Administration (FDA) Center for Tobacco Products (CTP) has had the authority to regulate the manufacture, distribution, and marketing of tobacco products in order to reduce the death and disease caused by tobacco use. Biomarkers could play an important role across a number of FDA regulatory activities, including assessing new and modified risk tobacco products and identifying and evaluating potential product standards. Methods On April 4-5, 2016, FDA/CTP hosted a public workshop focused on biomarkers of potential harm (BOPH) with participants from government, industry, academia, and other organizations. The workshop was divided into five sessions focused on: (1) overview of BOPH; (2) cardiovascular disease (CVD); (3) chronic obstructive pulmonary disease (COPD); (4) cancer; and (5) new areas of research. Results and Conclusions The deliberations from the workshop noted some promising BOPH but also highlighted the lack of systematic effort to identify BOPH that would have utility and validity for evaluating tobacco products. Research areas that could further strengthen the applicability of BOPH to tobacco regulatory science include the exploration of composite biomarkers as predictors of disease risk, "omics" biomarkers, and examining biomarkers using existing cohorts, surveys, and experimental studies. Implications This paper synthesizes the main findings from the 2016 FDA-sponsored workshop focused on BOPH and highlights research areas that could further strengthen the science around BOPH and their applicability to tobacco regulatory science.

Bioinform Biol Insights 2019; 13:1177932219882961. [PMID: 31666793 PMCID: PMC6798164 DOI: 10.1177/1177932219882961] [Citation(s) in RCA: 19] [Impact Index Per Article: 3.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/06/2019] [Accepted: 09/18/2019] [Indexed: 12/22/2022] Open
Abstract
Existing US epidemiological data demonstrate that consumption of smokeless
tobacco, particularly moist snuff, is less harmful than cigarette smoking.
However, the molecular and biochemical changes due to moist snuff consumption
relative to smoking remain incompletely understood. We previously reported that
smokers (SMK) exhibit elevated oxidative stress and inflammation relative to
moist snuff consumers (MSC) and non-tobacco consumers (NTC), based on
metabolomic profiling data of saliva, plasma, and urine from MSC, SMK, and NTC.
In this study, we investigated the effects of tobacco consumption on additional
metabolic pathways using pathway-based analysis tools. To this end, metabolic
pathway enrichment analysis and topology analysis were performed through
pair-wise comparisons of global metabolomic profiles of SMK, MSC, and NTC. The
analyses identified >8 significantly perturbed metabolic pathways in SMK
compared with NTC and MSC in all 3 matrices. Among these differentially enriched
pathways, perturbations of caffeine metabolism, energy metabolism, and arginine
metabolism were mostly observed. In comparison, fewer enriched metabolic
pathways were identified in MSC compared with NTC (5 in plasma, none in urine
and saliva). This is consistent with our transcriptomics profiling results that
show no significant differences in peripheral blood mononuclear cell gene
expression between MSC and NTC. These findings, taken together with our previous
biochemical, metabolomic, and transcriptomic analysis results, provide a better
understanding of the relative changes in healthy tobacco consumers, and
demonstrate that chronic cigarette smoking, relative to the use of smokeless
tobacco, results in more pronounced biological changes, which could culminate in
smoking-related diseases.

Abstract
The effects of nicotine replacement therapy (NRT)-aided smoking cessation on vascular function are not fully clarified. We investigated 100 healthy smokers who were motivated to quit and received NRT for a 3-month period. Vascular endothelial function (measured by reactive hyperemia-peripheral arterial tonometry [RH-PAT]), arterial stiffness (measured by augmentation index [AI] and brachial-ankle pulse wave velocity [baPWV]), and systemic inflammation markers (including serum soluble intercellular adhesion molecule-1 [sICAM-1] and interleukin-1β [IL-1β]) were assessed at baseline and 3 and 12 months of follow-up. After 3 months of intervention, endothelial function, arterial stiffness, and inflammatory markers significantly improved (RH-PAT increased, AI and baPWV decreased, sICAM-1 and IL-1β decreased, all P < .05) for the participants who abstained from smoking completely, but for those who did not abstained completely, RH-PAT, AI, baPWV, and IL-1β remained unchanged. At 12 months follow-up, endothelial function (RH-PAT), arterial stiffness (AI and baPWV), and inflammatory markers (sICAM-1 and IL-1β) were further improved in participants who abstained from smoking (P < .001), while the above parameters deteriorated in continued smokers (P < .05). In conclusion, vascular dysfunction can be reversible after NRT-aided smoking cessation in healthy smokers and vascular function could be further damaged if they continue smoking.

Abstract
Context: One approach to reducing the harm caused by cigarette smoking, at both individual and population level, is to develop, assess and commercialize modified risk alternatives that adult smokers can switch to. Studies to demonstrate the exposure and risk reduction potential of such products generally involve the measuring of biomarkers, of both exposure and effect, sampled in various biological matrices.Objective: In this review, we detail the pros and cons for using several biomarkers as indicators of effects of changing from conventional cigarettes to modified risk products.Materials and methods: English language publications between 2008 and 2017 were retrieved from PubMed using the same search criteria for each of the 25 assessed biomarkers. Nine exclusion criteria were applied to exclude non-relevant publications.Results: A total of 8876 articles were retrieved (of which 7476 were excluded according to the exclusion criteria). The literature indicates that not all assessed biomarkers return to baseline levels following smoking cessation during the study periods but that nine had potential for use in medium to long-term studies.Discussion and conclusion: In clinical studies, it is important to choose biomarkers that show the biological effect of cessation within the duration of the study.

Abstract
Background Among the different tobacco products that are available on the US market, cigarette smoking is shown to be the most harmful and the effects of cigarette smoking have been well studied. US epidemiological studies indicate that non-combustible tobacco products are less harmful than smoking and yet very limited biological and mechanistic information is available on the effects of these alternative tobacco products. For the first time, we characterized gene expression profiling in PBMCs from moist snuff consumers (MSC), compared with that from consumers of cigarettes (SMK) and non-tobacco consumers (NTC). Results Microarray analysis identified 100 differentially expressed genes (DEGs) between the SMK and NTC groups and 46 DEGs between SMK and MSC groups. However, we found no significant differences in gene expression between MSC and NTC. Both hierarchical clustering and principle component analysis revealed that MSC and NTC expression profiles were more similar than to SMK. Random forest classification identified a subset of DEGs which predicted SMK from either NTC or MSC with high accuracy (AUC 0.98). Conclusions PMBC gene expression profiles of NTC and MSC are similar to each other, while SMK exhibit distinct profiles with alterations in immune related pathways. In addition to discovering several biomarkers, these studies support further understanding of the biological effects of different tobacco products. Trial registration ClinicalTrials.gov.

Abstract
Ageing is linked to a number of changes in how the body and its organs function. On a molecular level, ageing is associated with a reduction of telomere length, changes in metabolic and gene-transcription profiles and an altered DNA-methylation pattern. Lifestyle factors such as smoking or stress can impact some of these molecular processes and thereby affect the ageing of an individual. Here we demonstrate by analysis of 77 plasma proteins in 976 individuals, that the abundance of circulating proteins accurately predicts chronological age, as well as anthropometrical measurements such as weight, height and hip circumference. The plasma protein profile can also be used to identify lifestyle factors that accelerate and decelerate ageing. We found smoking, high BMI and consumption of sugar-sweetened beverages to increase the predicted chronological age by 2–6 years, while consumption of fatty fish, drinking moderate amounts of coffee and exercising reduced the predicted age by approximately the same amount. This method can be applied to dried blood spots and may thus be useful in forensic medicine to provide basic anthropometrical measures for an individual based on a biological evidence sample.

Abstract
A randomized, multi-center study of adult cigarette smokers switched to tobacco-heating cigarettes, snus or ultra-low machine yield tobacco-burning cigarettes (50/group) for 24 weeks was conducted. Evaluation of biomarkers of biological effect (e.g. inflammation, lipids, hypercoaguable state) indicated that the majority of consistent and statistically significant improvements over time within each group were observed in markers of inflammation. Consistent and statistically significant differences in pairwise comparisons between product groups were not observed. These findings are relevant to the understanding of biomarkers of biological effect related to cigarette smoking as well as the risk continuum across various tobacco products (ClinicalTrials.gov Identifier: NCT02061917).

Abstract
Cardiovascular disease (CVD) biomarkers of biological effect (BoBE), including hematologic biomarkers, serum lipid-related biomarkers, other serum BoBE, and one physiological biomarker, were evaluated in adult cigarette smokers (SMK), smokeless tobacco consumers (STC), and non-consumers of tobacco (NTC). Data from adult males and females in the US National Health and Nutrition Examination Survey and a single site, cross-sectional study of healthy US males were analyzed and compared. Within normal clinical reference ranges, statistically significant differences were observed consistently for fibrinogen, C-reactive protein (CRP), hematocrit, mean cell volume, mean cell hemoglobin, hemoglobin, white blood cells, monocytes, lymphocytes, and neutrophils in comparisons between SMK and NTC; for CRP, white blood cells, monocytes, and lymphocytes in comparisons between SMK and STC; and for folate in comparisons with STC and NTC. Results provide evidence for differences in CVD BoBE associated with the use of different tobacco products, and provide evidence of a risk continuum among tobacco products and support for the concept of tobacco harm reduction.

Abstract
A study was conducted to evaluate biomarkers of biological effect and physiological assessments related to cardiovascular disease (CVD) among adult male cigarette smokers (SMK), moist snuff consumers (MSC) and non-consumers of tobacco (NTC). Additionally, biomarkers of tobacco and tobacco smoke exposure (BoE) were measured in spot urines and are reported here. Except for the BoE to nicotine and NNK, BoE were generally greater in SMK compared with MSC, and BoE were generally not different in comparisons of MSC and NTC. Results demonstrated that MSC had lower systemic exposures to many harmful and potentially harmful constituents than SMK, which is consistent with epidemiological data that indicate a differential in CVD risk between these groups.
