J Psychiatr Res 2024; 177:299-304. [PMID: 39059027 DOI: 10.1016/j.jpsychires.2024.07.029] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/11/2024] [Revised: 07/14/2024] [Accepted: 07/18/2024] [Indexed: 07/28/2024]
Abstract
We investigated the plasma tumor necrosis factor (TNF)-α levels between patients with schizophrenia remission and healthy controls, and the association between the plasma TNF-α levels and cognitive function and social function. This cross-sectional study included 48 patients with schizophrenia who fulfilled the remission criteria and 20 healthy controls. Plasma TNF-α levels were measured using the enzyme-linked immunosorbent assay, and cognitive function was assessed using the Japanese version of the Brief Assessment of Cognition in Schizophrenia (BACS-J). We measured social function using the Social Functioning Scale (SFS-J). The plasma TNF-α levels were significantly lower in the remission schizophrenia group (31.7 ± 27.4 ng/mL) compared to the heathy control group (55.1 ± 38.5 ng/mL) (P = 0.01). In contrast, no correlation was observed between the plasma levels of TNF-α and all BACS-J scores and all SFS-J scores in either group. This result suggests that plasma TNF-α levels may serve as a clinical biomarker of remission of schizophrenia and that the plasma TNF-α levels bore no association with cognitive function. Thus, TNF-α may have potential as a useful indicator of the therapeutic response in patients with schizophrenia.

Abstract
Secondhand vaping exposure is an emerging public health concern that remains understudied. In this study, saliva and exhaled emissions from ENDS users (secondhand) and non-ENDS users (baseline) were collected, firsthand emissions were generated using an automated ENDS aerosol generation system programmed to simulate puffing topography profiles collected from ENDS users. Particulate concentrations and sizes along with volatile organic compounds were characterized. We revealed puffing topography metrics as potential mediators of firsthand and secondhand particle and chemical exposures, as well as metabolic and respiratory health outcomes. Particle deposition modeling revealed that while secondhand emissions displayed smaller deposited mass, total and pulmonary particle deposition fractions were higher than firsthand deposition levels, possibly due to smaller secondhand emission particle diameters. Lastly, untargeted metabolomic profiling of salivary biomarkers of lung injury due to firsthand ENDS exposures revealed potential early indicators of respiratory distress that may also be relevant in bystanders exposed to secondhand vaping scenarios. By leveraging system toxicology, we identified 10 metabolites, including leukotriene D4, that could potentially serve as biomarkers for ENDS use, exposure estimation, and the prediction of vaping-related disease. This study highlights characterization of vaping behavior is an important exposure component in advancing our understanding of potential health effects in ENDS users and bystanders.

Ye Y, Wang CE, Zhong R, Xiong XM. Associations of the circulating levels of cytokines with risk of ankylosing spondylitis: a Mendelian randomization study. Front Immunol 2023; 14:1291206. [PMID: 38173728 PMCID: PMC10761470 DOI: 10.3389/fimmu.2023.1291206] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/08/2023] [Accepted: 12/08/2023] [Indexed: 01/05/2024] Open
Abstract
Background Observational studies have shown that changes in circulating cytokine/growth factor levels occur throughout the initiation and progression of ankylosing spondylitis (AS), yet whether they are etiologic or downstream effects remains unclear. In this study, we performed a summarized-level bidirectional Mendelian randomization (MR) analysis to shed light on the causal relationship between the two. Methods Genetic instrumental-variables (IVs) associated with circulating cytokine/growth factor levels were derived from a genome-wide association study (GWAS) of 8,293 European individuals, whereas summary data for the AS were obtained from a FinnGen GWAS of 166,144 participants. We used the inverse-variance-weighted (IVW) method as the main analysis for causal inference. Furthermore, several sensitivity analyses (MR-Egger, weighted median, MR-PRESSO and Cochran's Q test) were utilized to examine the robustness of the results. Finally, reverse MR analysis was performed to assess reverse causality between AS and circulating cytokine/growth factor levels. Results After Bonferroni correction, circulating levels of Cutaneous T-cell attracting (CTACK) and Monocyte specific chemokine 3 (MCP-3) were positively associated with a higher risk of AS (odds ratio [OR]: 1.224, 95% confidence interval [95% Cl]: 1.022 ~ 1.468, P = 0.028; OR: 1.250, 95% Cl: 1.016 ~ 1.539, P = 0.035). In addition, elevated circulating levels of Basic fibroblast growth factor (FGF-basic), Granulocyte colony-stimulating factor (G-CSF) and MCP-3 was considered a consequence of AS disease (β = 0.023, P = 0.017; β = 0.017, P = 0.025; β = 0.053, P = 0.025). The results of the sensitivity analysis were generally consistent. Conclusion The present study supplies genetic evidence for the relationship between circulating cytokine levels and AS. Targeted interventions of specific cytokines may help to reduce the risk of AS initiation and progression.

Abstract
BACKGROUND Epidemiological and experimental evidence has linked chronic inflammation to cancer aetiology. It is unclear whether associations for specific inflammatory biomarkers are causal or due to bias. In order to examine whether altered genetically predicted concentration of circulating cytokines are associated with cancer development, we performed a two-sample Mendelian randomisation (MR) analysis. METHODS Up to 31,112 individuals of European descent were included in genome-wide association study (GWAS) meta-analyses of 47 circulating cytokines. Single nucleotide polymorphisms (SNPs) robustly associated with the cytokines, located in or close to their coding gene (cis), were used as instrumental variables. Inverse-variance weighted MR was used as the primary analysis, and the MR assumptions were evaluated in sensitivity and colocalization analyses and a false discovery rate (FDR) correction for multiple comparisons was applied. Corresponding germline GWAS summary data for five cancer outcomes (breast, endometrial, lung, ovarian, and prostate), and their subtypes were selected from the largest cancer-specific GWASs available (cases ranging from 12,906 for endometrial to 133,384 for breast cancer). RESULTS There was evidence of inverse associations of macrophage migration inhibitory factor with breast cancer (OR per SD = 0.88, 95% CI 0.83 to 0.94), interleukin-1 receptor antagonist with endometrial cancer (0.86, 0.80 to 0.93), interleukin-18 with lung cancer (0.87, 0.81 to 0.93), and beta-chemokine-RANTES with ovarian cancer (0.70, 0.57 to 0.85) and positive associations of monokine induced by gamma interferon with endometrial cancer (3.73, 1.86 to 7.47) and cutaneous T-cell attracting chemokine with lung cancer (1.51, 1.22 to 1.87). These associations were similar in sensitivity analyses and supported in colocalization analyses. CONCLUSIONS Our study adds to current knowledge on the role of specific inflammatory biomarker pathways in cancer aetiology. Further validation is needed to assess the potential of these cytokines as pharmacological or lifestyle targets for cancer prevention.

Abstract
Musculoskeletal conditions are known to involve biological, psychological, social and, often, lifestyle elements. However, these domains are generally considered in isolation from each other. This siloed approach is unlikely to be adequate to understand the complexity of these conditions and likely explains a major component of the disappointing effects of treatment. This paper presents a hypothesis that aims to provide a foundation to understand the interaction and integration between these domains. We propose a hypothesis that provides a plausible link between psychology and lifestyle factors with tissue level effects (such as connective tissue dysregulation/accumulation) in musculoskeletal conditions that is founded on understanding the molecular basis for interaction between systemic and local inflammation. The hypothesis provides plausible and testable links between mind and body, for which empirical evidence can be found for many aspects. We present this hypothesis from the perspective of connective tissue biology and pathology (fibrosis), the role of inflammation locally (tissue level), and how this inflammation is shaped by systemic inflammation through bidirectional pathways, and various psychological and lifestyle factors via their influence on systemic inflammation. This hypothesis provides a foundation for new consideration of the development and refinement of personalized multidimensional treatments for individuals with musculoskeletal conditions.

Abstract
Cigarette smoking has a negative effect on respiratory and skeletal muscle function and is a risk factor for various chronic diseases. To assess the effects of 14 days of smoking cessation on respiratory and skeletal muscle function, markers of inflammation and oxidative stress in humans. Spirometry, skeletal muscle function, circulating carboxyhaemoglobin levels, advanced glycation end products (AGEs), markers of oxidative stress and serum cytokines were measured in 38 non-smokers, and in 48 cigarette smokers at baseline and after 14 days of smoking cessation. Peak expiratory flow (p = 0.004) and forced expiratory volume in 1 s/forced vital capacity (p = 0.037) were lower in smokers compared to non-smokers but did not change significantly after smoking cessation. Smoking cessation increased skeletal muscle fatigue resistance (p < 0.001). Haemoglobin content, haematocrit, carboxyhaemoglobin, total AGEs, malondialdehyde, TNF-α, IL-2, IL-4, IL-6 and IL-10 (p < 0.05) levels were higher, and total antioxidant status (TAS), IL-12p70 and eosinophil numbers were lower (p < 0.05) in smokers. IL-4, IL-6, IL-10 and IL-12p70 had returned towards levels seen in non-smokers after 14 days smoking cessation (p < 0.05), and IL-2 and TNF-α showed a similar pattern but had not yet fully returned to levels seen in non-smokers. Haemoglobin, haematocrit, eosinophil count, AGEs, MDA and TAS did not significantly change with smoking cessation. Two weeks of smoking cessation was accompanied with an improved muscle fatigue resistance and a reduction in low-grade systemic inflammation in smokers.

Abstract
Background: Allergies and smoking are common reasons for nasal mucosa inflammations, which in turn, cause nasal obstructions. Nevertheless, the impact of coexisting allergies and smoking on nasal mucosa inflammation has not been studied.Objectives: To study the impact of smoking with relation to allergies on nasal mucosa histology and to characterize an immunologic profile using immunohistochemical (IHC) staining.Methods: A cross-sectional study. Nasal biopsies of inferior turbinates from smokers with different allergic statuses were compared. Demographics, comorbidities, histologic, and immunohistochemical (IHC) staining of CD3, CD68, CD 20, and CD138 receptors were compared and analyzed.Results: A total of 53 patients were included, of which 20 (37.7%) were smokers, and 20 (37.7%) had allergic backgrounds. Smokers, both allergic and non-allergic, demonstrated reduced edema compared to the control group (p Value = 0.034) and significantly lower eosinophil density in the stroma compared to the allergic nonsmokers' group (p Value = 0.04). Smokers had a significant negative correlation between the number of cigarettes per day and the expression of CD20 in the stroma (-0.452, p Value = 0.045) and the epithelium (-0.432, p Value = 0.057) in IHC staining. Allergic smokers had a negative correlation (-0.705, p Value = 0.023) between the number of cigarettes per day and the CD68 marked cell expression in the epithelium.Conclusion: The coexistence of an allergic background and smoking alters known immunologic responses within the nasal mucosa. Smoking may have an immunosuppressive role in the nasal mucosa in both innate and humoral immune systems.

Abstract
BACKGROUND Ankylosing spondylitis (AS) is a chronic systemic inflammatory disease that can progressively restrict spinal mobility. OBJECTIVE This study aimed to investigate how smoking cessation by AS patients affects disease activity and their psychological state, physical mobility, lung function, and quality of life. MATERIALS AND METHODS This was a longitudinal, single-blind, controlled, and observational study on 92 AS patients. Pulmonary function test, Bath Ankylosing Spondylitis Disease Activity Index (BASDAI), Bath Ankylosing Spondylitis Functional Index, Bath Ankylosing Spondylitis Metrology Index, chest expansion, Short-Form 36, and Ankylosing Spondylitis Quality of Life were evaluated. The patients were divided into smokers (group 1 = 54) and nonsmokers (group 2 = 38). The smokers were divided further into subgroups of those who quit smoking (group 1a = 17) and those who did not (group 1b = 37). Groups 1a and 1b patients were compared in terms of their baseline data and data 6 months after smoking cessation. In addition, group 1a patients' baseline data and data 6 months after smoking cessation were compared statistically. RESULTS There was no statistically significant difference between groups 1a and 1b after 6 months in terms of the evaluated parameters, except for BASDAI. Bath Ankylosing Spondylitis Disease Activity Index was significantly lower in group 1a than group 1b (p = 0.02), indicating that. When the baseline data and data after 6 months of group 1a were compared, a significant improvement was found in BASDAI (p = 0.001), Bath Ankylosing Spondylitis Functional Index (p = 0.001), chest expansion (p = 0.001), ankylosing spondylitis quality of life (p = 0.003), and subparameters physical function (p = 0.015), physical role strength (p = 0.05), power/live/vitality (p = 0.025), social functioning (p = 0.039), pain (p = 0.036), and general health perception (p = 0.05) of Short-Form 36, as well as forced expiratory volume in the first second (p = 0.003) and forced vital capacity (p = 0.007). CONCLUSIONS We observed significant improvements in disease activity, physical mobility, and quality of life in AS patients who quit smoking.

Abstract
Schizophrenia, a multisystem disorder with an unknown etiology, is associated with several immune dysfunctions, including abnormal levels of circulating cytokines. In this review, we investigated the changes of cytokines in schizophrenic patients, their connection with behavioral symptoms severity and their potential clinical implications. We also assessed the possible causative role of abnormal cytokine levels in schizophrenia pathogenesis. Based on meta-analyses, we categorized cytokines according to their changes in schizophrenic patients into four groups: (1) increased cytokines, including interleukin (IL)-6, tumor necrosis factor (TNF)-α, IL-1β, IL-12, and transforming growth factor (TGF)-β, (2) non-altered cytokines, including IL-2, IL-4, and IL-17, (3) increased or non-altered cytokines, including IL-8 and interferon (IFN)-γ, and (4) IL-10 with increased, decreased, and non-altered levels. Notably, alterations in cytokines may be variable in four different categories of SP, including first-episode and drug-naïve, first-episode and non-drug-naïve, stable chronic, and chronic in acute relapse. Furthermore, disease duration, symptoms severity, incidence of aggression, and cognitive abilities are correlated with levels of certain cytokines. Clinical implications of investigating the levels of cytokine in schizophrenic patients include early diagnosis, novel therapeutic targets development, patient stratification for choosing the best therapeutic protocol, and predicting the prognosis and treatment response. The levels of IL-6, IL-8, IFN-γ, IL-2 are related to the treatment response. The available evidence shows a potential causative role for cytokines in schizophrenia development. There is a substantial need for studies investigating the levels of cytokines before disease development and delineating the therapeutic implications of the disrupted cytokine levels in schizophrenia.

Feasibility Outcomes of a Pilot Randomized Clinical Trial to Increase Cruciferous and Green Leafy Vegetable Intake in Posttreatment Head and Neck Cancer Survivors. J Acad Nutr Diet 2019; 119:659-671. [PMID: 30661935 PMCID: PMC6433521 DOI: 10.1016/j.jand.2018.11.005] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/12/2018] [Revised: 11/05/2018] [Accepted: 11/07/2018] [Indexed: 01/24/2023]
Abstract
BACKGROUND Higher intakes of cruciferous vegetables (CVs) and green leafy vegetables (GLVs) in observational studies are associated with improvements in survival and cancer-related biomarkers in patients diagnosed with head and neck cancer (HNC). These results have yet to be corroborated in a randomized clinical trial (RCT). OBJECTIVE Determine the feasibility of implementing a 12-week RCT to increase CV and GLV intake in posttreatment HNC survivors. DESIGN AND PARTICIPANTS This was a two-arm RCT conducted among 24 posttreatment HNC survivors. Survivors were recruited from a southeastern, National Cancer Institute-designated Comprehensive Cancer Center between January 2015 and September 2016. INTERVENTION There were two groups: (1) an experimental group (n=12) receiving weekly 15- to 30-minute telephone dietary counseling from a registered dietitian nutritionist stressing 2.5 cups per week CVs and 3.5 cups per week GLVs, and (2) an attention control group (n=12) receiving weekly 15- to 30-minute telephone dietary counseling from a registered dietitian nutritionist focusing on general healthy eating for cancer survivors. Participants completed a baseline survey, three 24-hour dietary recalls, phlebotomy, and anthropometric measures prior to randomization and at the end of the 12-week study period. The experimental group also completed weekly vegetable record recalls. MAIN OUTCOME MEASURES Primary outcomes included feasibility, recruitment, retention, adherence, and safety. Secondary outcomes included inflammatory markers and carotenoids. STATISTICAL ANALYSES PERFORMED Descriptive statistics were generated for demographic, epidemiological, and clinical variables as well as the primary feasibility outcomes. Between- and within-group comparisons of mean serum cytokine and carotenoid levels were performed using appropriate statistical tests depending on their respective distributions for the purpose of generating preliminary effect sizes. RESULTS Overall, 350 incident HNC cases were screened for eligibility, and 98 were eligible for study participation. Reasons for ineligibility and exclusion included deceased (n=93); wrong or inactive telephone numbers, or unable to be reached, or lost to follow-up (n=93); not meeting inclusion criteria (n=39); and too ill to participate (n=27). Of the 98 eligible HNC cases, 24 agreed to participate, for an enrollment rate of 25%. The most common reason for nonparticipation was distance (n=48), as participants were asked to report for two on-site assignments. The retention rate was 96%. Mean intervention adherence rates for weekly goals were 67% CV, 74% GLV, and 71% overall. Completion rate of weekly counseling calls was 90%. The experimental group reported an overall mean increase of 5.5 cups GLV and 3.5 cups CV per week from baseline intake, respectively. No significant between- or within-arm differences were observed for inflammatory markers or carotenoids. CONCLUSION A posttreatment intervention aimed at increasing CV and GLV intake in HNC survivors is feasible. A larger RCT is needed to assess the efficacy of this intervention on disease outcomes.

Abstract
OBJECTIVE When an autogenous vein is harvested and used for arterial bypass, it suffers physical and biologic injuries that may set in motion the cellular processes that lead to wall thickening, fibrosis, stenosis, and ultimately graft failure. Whereas the injurious effects of surgical preparation of the vein conduit have been extensively studied, little is known about the influence of the clinical environment of the donor leg from which the vein is obtained. METHODS We studied the cellular responses of fresh saphenous vein samples obtained before implantation in 46 patients undergoing elective lower extremity bypass surgery. Using an ex vivo model of response to injury, we quantified the outgrowth of cells from explants of the adventitial and medial layers of the vein. We correlated this cellular outgrowth with the clinical characteristics of the patients, including the Wound, Ischemia, and foot Infection classification of the donor leg for ischemia, wounds, and infection as well as smoking and diabetes. RESULTS Cellular outgrowth was significantly faster and more robust from the adventitial layer than from the medial layer. The factors of leg ischemia (P < .001), smoking (P = .042), and leg infection (P = .045) were associated with impaired overall outgrowth from the adventitial tissue on multivariable analysis. Only ischemia (P = .046) was associated with impaired outgrowth of smooth muscle cells (SMCs) from the medial tissue. Co-culture of adventitial cells and SMCs propagated from vein explants revealed that adventitial cells significantly inhibited the growth of SMCs, whereas SMCs promoted the growth of adventitial cells. The AA genotype of the -838C>A p27 polymorphism (previously associated with superior graft patency) enhanced these effects, whereas the factor of smoking attenuated adventitial cell inhibition of SMC growth. Comparing gene expression, the cells cultured from the media overexpress Kyoto Encyclopedia of Genes and Genomes pathways associated with inflammation and infection, whereas those from the adventitia overexpress gene families associated with development and stem/progenitor cell maintenance. CONCLUSIONS The adverse clinical environment of the leg may influence the biologic behavior of the cells in the vein wall, especially the adventitial cells. Chronic ischemia was the most significant factor that retards adventitial cell outgrowth. The cells arising from the vein adventitia may be key players in determining a healthy adaptive or a pathologic response to the injuries associated with vein grafting.

Abstract
Nutritional abnormalities are frequent in different chronic respiratory diseases such as chronic obstructive pulmonary disease (COPD), bronchiectasis, cystic fibrosis (CF), interstitial fibrosis and lung cancer, having important clinical consequences. However, nutritional abnormalities often remained underdiagnosed due to the relative lack of awareness of health professionals. Therefore, systematic anthropometry or even better, assessment of body composition, should be performed in all patients with chronic respiratory conditions, especially following exacerbation periods when malnutrition becomes more accentuated. Nutritional abnormalities very often include the loss of muscle mass, which is an important factor for the occurrence of muscle dysfunction. The latter can be easily detected with the specific assessment of muscle strength and endurance, and also negatively influences patients' quality of life and prognosis. Both nutritional abnormalities and muscle dysfunction result from the interaction of several factors, including tobacco smoking, low physical activity-sedentarism, systemic inflammation and the imbalance between energy supply and requirements, which essentially lead to a negative balance between protein breakdown and synthesis. Therapeutic approaches include improvements in lifestyle, nutritional supplementation and training. Anabolic drugs may be administered in some cases.

Abstract
Inflammation plays a key role in the initiation, progression, and clinical manifestation of atherosclerosis. Cigarette smoking is a risk factor for atherosclerosis and cardiovascular disease. The aim of the current study was to investigate the serum concentrations of 12 cytokines and growth factors (EGF, INF-γ, IL-1α/-1β/-2/-4/-6/-8/-10, MCP-1, TNF-α, and VEGF) in an Iranian population, including 192 smokers, comparing these values with concentrations in nonsmokers. One hundred and ninety-two cases were enrolled from the Mashhad University of Medical Sciences. Of these cases, 82 were cigarette smokers and 110 were nonsmokers. Sex and age were matched for the two groups. The serum concentration of 12 cytokines and growth factors were determined using EV-3513-cytokine-biochip arrays, by competitive chemiluminescence immunoassays. The level of serum MCP-1 was significantly ( p < .001) lower in the female group of cigarette smokers (mean = 88.1 dL/ng), compared with nonsmokers (mean = 155.6 dL/ng). There were no significant differences for the other cytokines and growth factors between the groups. Our finding demonstrate the association of MCP-1 with cigarette smoking, supporting further studies in larger population on evaluating the role of cigarette smoking on pro-/anti-inflammatory cytokines.

Abstract
INTRODUCTION Nitric oxide (NO) modulates inflammatory reactions, having beneficial or toxic effects depending on the concentration. Its elevation can cause proinflammatory effects amplifying the inflammatory process with the participation of cytokines. Smoking has a negative impact on health and is considered one of the risk factors that influence disease development facilitating inflammatory processes. AIM To compare the serum concentration of NO and cytokines in smokers at baseline and after 4months of abstinence treatment. METHODS Blood samples which were collected to obtain the serum, at baseline and after 4months, were stored at -80°C until analysis. NO was measured by the total dose of nitrite determined by the Greiss method. CBA was the used technique to determine the concentration of cytokines in supernatants serum. The initial and final results of NO, TNF-α, IL-1, IL-6, IL-8, IL-10 and IL-12 that remained after 4months treatment were compared. Wilcoxon test was used to compare the data and Spearman test for correlations between NO and other variables. A significance level of p<0.05 was adopted. RESULTS The analysis of NO observed a significant reduction (p=0.001) of the initial median value of 18.80 (3.55-80.01) μmol/L to 8.10 (2.85-14.97) μmol/L after 4months of treatment. There were no significant differences in cytokines from baseline to the end of treatment. CONCLUSION The results may not mean harm to the body, but an adaptive process, decreasing the metabolism of abstinents due to the reduction of the use of nicotine.

Abstract
INTRODUCTION The mechanisms underlying the effects of cigarette smoke and smoking cessation on respiratory secretion, especially in the larynx, remain unclear. OBJECTIVES The aims of this study were to determine the effects of cigarette smoke and smoking cessation on laryngeal mucus secretion and inflammation, and to investigate the effects of glucocorticoid administration. METHODS We administered cigarette smoke solution (CSS) to eight-week-old male Sprague Dawley rats for four weeks, then examined laryngeal mucus secretion and inflammatory cytokine expression on days 1, 28 and 90 after smoking cessation. We also investigated the effects of the glucocorticoid triamcinolone acetonide when administered on day 1 after smoking cessation. RESULTS Exposure to CSS resulted in an increase in laryngeal mucus secretion that was further excacerbated following smoking cessation. This change coincided with an increase in the expression of mRNA for the inflammatory cytokines tumor necrosis factor and interleukin-6, as well as mRNA for MUC5AC, which is involved in mucin production. Triamcinolone suppressed CSS-induced laryngeal mucus hypersecretion and pro-inflammatory cytokine production. CONCLUSION Cigarette smoke-associated inflammation may contribute to the exacerbated laryngeal mucus hypersecretion that occurs following smoking cessation. The inflammatory response represents a promising target for the treatment of cigarette smoke-associated mucus hypersecretion.

Abstract
OBJECTIVE Tobacco smoke is a significant risk factor for respiratory diseases. The purpose of this study is to analyze the cytologic and functional features of nasal mucosa in smokers, nonsmokers, and ex-smokers to evaluate if nasal alterations in smokers are permanent or reversible conditions after smoking cessation. STUDY DESIGN Case series with planned data collection. SETTING University medical center. SUBJECTS AND METHODS Ninety healthy volunteers recruited from the staff of Alfredo Fiorini Hospital, Sapienza University of Rome, were enrolled in this prospective study from October to November 2013. We divided the cases according to smoking habits (smokers, nonsmokers, ex-smokers). Each group was composed of 30 subjects. Cytologic features of nasal mucosa and effectiveness of nasal mucociliary clearance were studied, focusing on 4 parameters: (1) nasal mucociliary clearance, assessed by saccharin nasal transit time; (2) ratio between the number of ciliated cells and goblet cells, analyzed by microscopic observation of cytologic specimens of nasal mucosa that had undergone May Grunwald Giemsa staining; (3) evaluation of ciliary motility; and (4) time of ciliary movement of ciliated cells analyzed by phase-contrast microscopy. RESULTS All parameters were significantly reduced in the smokers compared to the nonsmokers. There were no statistically significant differences between the nonsmoker and ex-smoker groups. CONCLUSION Cigarette smoking causes cytologic modifications of nasal mucosa that influence the effectiveness of mucociliary clearance. Our preliminary study suggests that these changes are not permanent and that nasal mucosa of ex-smokers recovers normal cytologic and functional features.
