pmid sentence
32189428 Here, we focus on those individuals who have been exposed to nicotine prior to their exposure to the virus. […] We predict that these individuals are ‘primed’ to be at higher risk because nicotine can directly impact the putative receptor for the virus (ACE2) and lead to deleterious signaling in lung epithelial cells.
32238438 Moreover, we predict that nicotine exposure through various kinds of smoking (cigarettes, e-cigarettes, or vape) can increase the risk for COVID19 neuroinfection based on known functional interactions between the nicotinic receptor and ACE2.
32305506 We decided to use the analogy of a play and speculate about the possible impact in this tragedy of 1) air pollution via the interference of nitrogen dioxide on ACE2 expression; 2) the dual role of nicotine; 3) the hypothetical involvement of ACE2 polymorphisms, the relationships of which with ethnic factors and susceptibility to cardiovascular disease seems intriguing; 4) the impact on the severity of infection of hypertension and related medications acting on the renin/angiotensin system, and, finally, 5) the possible helpful role of chloroquine, thanks to its capacity of modifying ACE2 affinity to the viral spike protein by altering glycosylation.
32385628 Although the generalized advice to quit smoking as a measure to reduce health risk remains valid, the findings, together with the well-established immunomodulatory effects of nicotine, suggest that pharmaceutical nicotine should be considered as a potential treatment option in COVID-19.
32420934 Some authors, noticing that reported smoking prevalence among hospitalized patients was substantially below smoking prevalence in the corresponding populations, speculated a protective role of nicotine.
32470789 recent studies have provided novel evidence regarding the effect of nicotine agonists on the prevention or modulation of cytokines storm and reduction of infection. […] In this study we tried to attempt to address these issues from a therapeutic perspective of nicotine agonists in this manner and we describe one of the most challenging theories of immunotherapy in coronavirus-19 (COVID-19).
32500928 Starting with the origin of the virus, we then discuss the effect of ibuprofen and nicotine on the severity of the disease.
32522666 This suggests that nicotine may have some preventive or modulatory effect on the inflammatory response in the lungs. […] Because it is known that the response to, and resolution of the SARS-CoV-2 infection depends mainly on the lung macrophages, we discuss the recent scientific findings, which may explain why and how nicotine may modulate lung macrophage response during COVID-19 infection.
32552811 Adult wild-type (WT), nAChRα7 knockout (KO), and lung epithelial cell-specific KO (nAChRα7 CreCC10) mice were exposed to e-cig aerosol containing propylene glycol (PG) with or without nicotine. […] Sub-chronic e-cig exposure with nicotine increased inflammatory cellular influx of macrophages and T-lymphocytes including increased pro-inflammatory cytokines in BALF and increased SARS-Cov-2 Covid-19 ACE2 receptor, whereas nAChRα7 KO mice show reduced inflammatory responses associated with decreased ACE2 receptor. […] Moreover, MMP12 was increased significantly in male mice exposed to PG with or without nicotine in a nAChRα7-dependent manner. […] Additionally, sub-chronic e-cig exposure with or without nicotine altered the abundance of ECM proteins, such as collagen and fibronectin, significantly in a sex-dependent manner, but without the direct role of nAChRα7 gene. […] Overall, sub-chronic e-cig exposure with or without nicotine affected lung inflammation and repair responses/ECM remodeling, which were mediated by nAChRα7 in a sex-dependent manner.
32595653 Nicotine, an exogenous α7nAchR agonist, is clinically used in ulcerative colitis to counteract inflammation. […] In conclusion, our hypothesis proposes that nicotine could constitute a novel potential CRS therapy in severe SARS-CoV-2 patients.
32609839 Given the evidence of this ecological study, and of several other studies that found an underrepresentation of smoking prevalence in hospitalized cases, it may be worth examining, in laboratory experiments and controlled human trials, if nicotine offers any protection against COVID-19.
32626554 Considering the role of cigarette smoking in the pathogenesis of lung diseases and the effect of nicotine on expression of the entry receptor for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), it is important to determine the implications of smoking in COVID-19.
32637059 However, the hypothesis that nicotine may have a protective effect in COVID-19 that is partially masked by smoking-related toxicity and by the abrupt cessation of nicotine intake when smokers are hospitalized should be explored in laboratory studies and clinical trials using pharmaceutical nicotine products.
32643078 Seventy-one (19.9%) of the subjects used nicotine tape, 268 (75.1%) used varenicline, and 18 (5.0%) used both.
32657671 Considering the benefits of smoking cessation in this vulnerable population, the current pandemic should be used as an opportunity to further enforce smoking cessation in mental health facilities and encourage nicotine replacement therapy alongside cessation counseling.
32710733 In addition, the functioning of the cholinergic anti-inflammatory pathway may be determined by nicotine. […] Pharmacological nicotine products are widely available, and their role in COVID-19-mediated AKI can be further evaluated.
32752138 Both smoking and use of nicotine and flavor-containing e-cigs led to upregulation of pro-inflammatory cytokines and inflammasome-related genes. […] Specifically, chemokines including CCL20 and CXCL8 are upregulated in smokers, and CCL5 and CCR1 are upregulated in flavor/nicotine-containing e-cig users. […] Vaping flavor and nicotine-less e-cigs, however, did not lead to significant cytokine dysregulation and inflammasome activation.
32753136 Men were older (mean age, 55.0±17.7 years vs 51.1±17.9 years; P<.001 and had a higher prevalence of hypertension diabetes coronary disease obstructive pulmonary nicotine dependence heart failure but lower obesity.> </.001>
32757420 Additionally, the postulated protective effects of nicotine and nitric oxide, which may presumably reduce the risk of a “cytokine storm” in infected individuals, deserve assessment by controlled clinical trials.
32757951 The reports suggesting a beneficial effect of nicotine on coronavirus disease 2019 (COVID-19) severity may encourage smoking.
32763662 Apart from nicotine or other chemicals contained in tobacco smoke, we propose that a single-stranded RNA virus that infects tobacco leaves, tobacco mosaic virus (TMV), might be implicated in this effect.
32788164 Plausible biologic mechanisms by which smoking might be protective in COVID-19 include an anti-inflammatory effect of nicotine, a blunted immune response in smokers (reducing the risk of a cytokine storm in COVID-19) and increased nitric oxide in the respiratory tract (which may inhibit replication of SARS-CoV-2 and its entry into cells).
32790936 Although conflicting hypotheses on the potential role of nicotine in COVID-19 pathology have recently been offered, we believe that nicotine itself, through its interaction with the nicotinic cholinergic system, as well as ACE2, may not only be of use in a variety of neuropsychiatric and neurodegenerative diseases, but may also be of potential use in COVID-19. […] Thus, on one hand, while we strongly support smoking cessation as a means of harm reduction associated with COVID-19, on the other hand, we support a potential therapeutic role for nicotine, nicotinic agonists, or positive allosteric modulators of nicotinic cholinergic receptors in COVID-19, owing to their varied effects including mood regulation, anti-inflammatory, and purported interference with SARS-CoV-2 entry and/or replication.
32796217 PLH were more likely to be men, African-American, obese and have concurrent hypertension, diabetes, chronic kidney disease and nicotine dependence compared with non-PLH cohort (all P values <0.05). […] We performed 1 : 1 matching for BMI, diabetes, hypertension, chronic lung diseases, chronic kidney disease, race, history of nicotine dependence and sex.
32800868 Overall, pathophysiological data showed an increased risk of infections for individuals with Substance Use Disorders (SUD) and a possible protective role of nicotine.
32802824 In the era of this pandemic, the role of medicinal nicotine in the prevention and treatment of #COVID19 disease should be evaluated in placebo-controlled trials, while smoking cessation should be further promoted as a general public health measure
32823591 Nicotine and other nicotinic cholinergic agonists may protect nAChRs and thus have therapeutic value in COVID-19 patients.
32835124 Nicotine patches and Colchicine have also been suggested as potential therapies due to Furin mediated inhibition of COVID-19.
32837982 While nicotine and ivermectin may be blocking transport abilities of the virus or its components, famotidine, remdesivir and chloroquine in combination with zinc ions can deactivate important enzymes needed for the replication of the virus.
32878480 The severity of coronavirus disease 2019 (COVID-19) is linked to an increasing number of risk factors, including exogenous (environmental) stimuli such as air pollution, nicotine, and cigarette smoke.
32890356 The aim of this paper is to enhance the importance of providing up to date informations about nicotine and tobacco use in connection with the SARS-CoV-2-related conditions. […] Nicotine replacement therapy and quitline counseling were provided and no major withdrawal symptoms were declared.
32896206 In experimental rodent studies initially designed to study the effect of electronic cigarette use on the cardiovascular system, we observed an E-cigarette or vaping product use-associated lung injury-like condition that occurred acutely after use of a nichrome heating element at high power, without the use of tetrahydrocannabinol, vitamin E, or nicotine. […] Electronic cigarette users should be cautioned about the potential danger of operating electronic cigarette units at high settings; the possibility that certain heating elements may be deleterious; and that E-cigarette or vaping product use-associated lung injury may not be dependent upon tetrahydrocannabinol, vitamin E, or nicotine.
32918300 To estimate (1) associations between self-reported COVID-19, hand-washing, smoking status, e-cigarette use and nicotine replacement therapy (NRT) use and (2) the extent to which COVID-19 has prompted smoking and vaping quit attempts and more smoking inside the home. […] With the exception of hand-washing before face-touching, engagement in hand-washing behaviours was high (> 85%), regardless of nicotine use. […] In England, current smokers and long-term ex-smokers appear to have higher odds of self-reported COVID-19 compared with never smokers in adjusted analyses, but there were no large differences between people who used nicotine replacement therapy or e-cigarettes. […] Engagement in hand-washing appears to be high, regardless of nicotine or tobacco use.
32941292 Preferences were assessed in relation to: (i) specific forms of tobacco cessation support (eg, nicotine replacement therapy (NRT) and various counseling formats); (ii) information sources (eg, government officials, doctors); and (iii) channels via which to receive relevant information (eg, television, social media).
32970973 Additional topics included affordable telehealth services, research from France on the relationship between nicotine and COVID-19, concerns about gambling addiction, and changing patterns in substance misuse as drug availability varies.
33029618 Changes in smoking patterns varied with nicotine dependence, motivation to quit, and financial stability since COVID-19.
33033170 Further, we have shown possible interactions between nicotine/smoking and ACE2 in the lungs and brain which could aggravate the transmission and pathobiology of COVID-19 resulting in a poor disease outcome. […] It focuses on the potential negative impact of tobacco and nicotine exposure on the outcomes of this disease by interaction with the ACE2 receptor.
