Chronic obstructive pulmonary disease (COPD) is increasingly recognized as a systemic disease that is associated with increased serum levels of markers of systemic inflammation. The triggering receptor expressed on myeloid cells 1 (TREM-1) is a recently identified activating receptor on neutrophils, monocytes, and macrophage subsets. TREM-1 expression is upregulated by microbial products such as the toll-like receptor ligand lipoteichoic acid of Gram-positive or lipopolysaccharides of Gram-negative bacteria. In the present study, sera from 12 COPD patients (GOLD stages I–IV,FEV151±6%) and 10 healthy individuals were retrospectively analyzed for soluble TREM-1 (sTREM-1) using a newly developed ELISA. In healthy subjects, sTREM-1 levels were low (median 0.25 ng/mL, range 0–5.9 ng/mL). In contrast, levels of sTREM-1 in sera of COPD patients were significantly increased (median 11.68 ng/mL, range 6.2–41.9 ng/mL,P<.05). Furthermore, serum levels of sTREM-1 showed a significant negative correlation with lung function impairment. In summary, serum concentrations of sTREM-1 are increased in patients with COPD. Prospective studies are warranted to evaluate the relevance of sTREM-1 as a potential marker of the disease in patients with COPD.

The risk of chronic obstructive pulmonary disease (COPD), as well as thyroid diseases increases with age. COPD is a common systemic disease associated with chronic inflammation. Many endocrinological disorders, including thyroid gland diseases are related to systemic inflammation. Epidemiological studies suggest that patients with COPD are at higher risk of thyroid disorders. These associations are not well-studied and thyroid gland diseases are not included on the broadly acknowledged list of COPD comorbidities. They may seriously handicap quality of life of COPD patients. Unfortunately, the diagnosis may be difficult, as many signs are masked by the symptoms of the index disease. The comprehension of the correlation between thyroid gland disorders and COPD may contribute to better care of patients. In this review, we attempt to revise available literature describing existing links between COPD and thyroid diseases. The signs or symptoms of thyroid disorders may be non-specific, especially among the elderly, therefore the differential diagnosis between symptoms of COPD and symptoms related to thyroid disease can cause difficulties. Many data show higher risk of thyroid hormones alterations in COPD patients. Hypothyroidism may influence respiration by different mechanisms, even in subjects with intact respiratory system. Therefore, it is hard to distinguish whether hormonal changes are the reason or a consequence of different respiratory signs and symptoms. In some instances, the correction of hormonal alternations may improve the qua­lity of life of COPD patients and other disease outcomes. The comprehension of an association between COPD, thyroid gland function and thyroid disorders may provide important information about the systemic nature of COPD.

Background: Chronic obstructive pulmonary disease (COPD) is a major health issue worldwide. Introduction: This study aimed to evaluate the effect of aerobic exercises at steep surfaces on Apo A1 and Apo B serum levels and their ratio in COPD patients. Methods: This interventional study was undertaken on 16 COPD patients. The sample was selected by using the random sampling method. Patients were randomly divided into 2 groups of 8 members: uphill and downhill. Spirometry was conducted prior to the exercises and pulmonary volumes were measured. Aerobic exercises (stationary bicycle and treadmill) were started 3 times a week for 8 weeks. The duration of exercises in each session was determined based on the patients’ ability (30-40 min). In the first and second group, exercises were performed on sloped surfaces that were downwards and upwards at a 10-degree angle, respectively. Blood samples were taken from the patients before and after the 8 weeks. Apo A1 and Apo B serum levels and Apo A1 to Apo B ratio were measured. Data were analyzed by SPSS software. P<0.05 was considered statistically significant. Results: ApoA1/Apo B ratio in the uphill group before and after the intervention was 1.43±0.21 and 1.53±0.24 mg/dL, respectively, with P-value=0.36. In the downhill group, this value was 1.27±0.17 and 1.30±0.18, respectively, with a P-value=0.032. Conclusion: In light of the results of the present study, incorporating downhill exercises in COPD patients' rehabilitation program can help improve pulmonary function and prevent atherosclerotic events.

ObjectiveThe present study was designed to investigate the biomarkers levels of fractalkine (FKN), neutrophil elastase (NE) and matrix metalloproteinase-12 (MMP-12) in chronic obstructive pulmonary disease (COPD) with ‘exacerbator with emphysema phenotype’ and to evaluate the associations between the biomarkers levels and the severity of disease by spirometric measurements.MethodsA total of 84 COPD patients and 49 healthy controls were enrolled in our study. ELISA were utilised to detect the FKN, MMP-12 and NE in serum from all subjects.ResultsFKN (p<0.001), NE (p=0.039) and MMP-12 (p<0.001) in serum of COPD patients showed higher levels than that of healthy control subjects. Serum FKN (p<0.001), MMP-12 (p<0.001) and NE (p=0.043) levels were significantly higher in severe and very severe COPD patients than that in mild and moderate COPD patients. Circulating FKN, MMP-12 and NE expression levels were significantly elevated (p<0.001) in COPD smokers compared with COPD non-smokers. The smoke pack years were negatively correlated with FEV1%pred (r=−0.5036), FEV1/FVC ratio (r=−0.2847) (FEV, forced expiratory volume; FVC, forced vital capacity). Similarly, we observed a strong positive correlation between the smoke pack years and serum levels of FKN (r=0.4971), MMP-12 (r=0.4315) and NE (r=0.2754). FEV1%pred was strongly negatively correlated with cytokine levels of FKN (r=−0.4367), MMP-12 (r=−0.3295) and NE (r=−0.2684). Likewise, FEV1/FVC ratio was negatively correlated with mediators of inflammation levels of FKN (r=−0.3867), MMP-12 (r=−0.2941) and NE (r=−0.2153).ConclusionSerum FKN, MMP-12 and NE concentrations in COPD patients are directly associated with the severity of COPD with ‘exacerbator with emphysema phenotype’. This finding suggests that FKN, MMP-12 and NE might play an important role in the pathophysiology of COPD.

Chronic obstructive pulmonary disease (COPD) has been described as a systemic disease. Sarcopenia is one of the systemic effects that is related to several adverse outcomes. The objectives of this study were to estimate the prevalence of sarcopenia and to determine the factors associated with sarcopenia in COPD patients in Southeast Asia. This was a cross-sectional study of COPD patients who attended a COPD clinic from May 2015 to December 2016. Baseline characteristics were collected and dual-energy X-ray absorptiometry was used to measure skeletal muscle mass. Handgrip strength was used to assess muscle strength, and as a measurement of physical performance, the 6-min walk distance was used. One hundred and twenty-one participants were recruited. Most of them were men (92.6%). Prevalence of sarcopenia was 24% (29 cases). Independent factors associated with sarcopenia were age ≥ 75 years (adjusted odds ratio (AOR) 13.3, severity of COPD (AOR 19.2 and 13.4 for moderate and severe COPD), Modified Medical Research Council (MMRC) scale (AOD 1.9), and obesity (AOR 0.04). Sarcopenia affects about one-quarter of COPD patients. Age, severity of COPD, MMRC scale, and BMI status were the factors associated with sarcopenia.

Background: COPD (Chronic obstructive pulmonary disease) is considered as a systemic disease due to associated systemic inflammation which can manifest as metabolic syndrome or its component illnesses. This study was undertaken to determine the proportion of metabolic syndrome in patients with COPD.Methods: 51 patients with COPD were compared with equal number of age and gender matched controls. GOLD (Global Initiative for Chronic Obstructive Lung Disease) criteria were used for diagnosing COPD. Metabolic Syndrome (MS) was diagnosed based on modified NCEP:ATP III criteria (National cholesterol education Program Adult Treatment Panel III). Subjects were evaluated for hypertension, WC, FBS, and serum triglycerides and serum HDL (High-density lipoprotein) to diagnose MS.Results: Metabolic syndrome was diagnosed in 16 (31.4%) patients with COPD and in 8 (15.7%) controls. The proportion of individual parameters of MS in cases and controls was as follows: DM in 19 (37.3%) cases and 13 (25.5%) controls, hypertension in 21(41.2%) cases and 9 (17.6%) controls, low serum HDL in 31 (60.7%) cases and 22 (43.1%) controls increased WC in 14 (27.5%) cases and 7 (13.7%) controls and elevated serum TG in 12 (23.5%) cases and an equal number of controls.Conclusions: Metabolic syndrome and its parameters are more prevalent in COPD patients. Early detection and treatment of MS in COPD patients can prevent development of complications due to the combined effects of both diseases.

Introduction The oral cavity and pharynx have a rich sensory system composed of specialized receptors. The integrity of oropharyngeal sensation is thought to be fundamental for safe and efficient swallowing. Chronic obstructive pulmonary disease (COPD) patients are at risk for oropharyngeal sensory impairment due to frequent use of inhaled medications and comorbidities including gastroesophageal reflux disease. Objective This study aimed to describe and compare oral and oropharyngeal sensory function measured using noninstrumental clinical methods in adults with COPD and healthy controls. Method Participants included 27 adults (18 men, nine women) with a diagnosis of COPD and a mean age of 66.56 years ( SD = 8.68). The control group comprised 11 healthy adults (five men, six women) with a mean age of 60.09 years ( SD = 11.57). Spirometry measures confirmed reduced functional expiratory volumes (% predicted) in the COPD patients compared to the control participants. All participants completed a case history interview and underwent clinical evaluation of oral and oropharyngeal sensation by a speech-language pathologist. The sensory evaluation explored the detection of tactile and temperature stimuli delivered by cotton swab to six locations in the oral cavity and two in the oropharynx as well as identification of the taste of stimuli administered in 5-ml boluses to the mouth. Analyses explored the frequencies of accurate responses regarding stimulus location, temperature and taste between groups, and between age groups (“≤ 65 years” and “> 65 years”) within the COPD cohort. Results We found significantly higher frequencies of reported use of inhaled medications ( p < .001) and xerostomia ( p = .003) in the COPD cohort. Oral cavity thermal sensation ( p = .009) was reduced in the COPD participants, and a significant age-related decline in gustatory sensation was found in the COPD group ( p = .018). Conclusion This study found that most of the measures of oral and oropharyngeal sensation remained intact in the COPD group. Oral thermal sensation was impaired in individuals with COPD, and reduced gustatory sensation was observed in the older COPD participants. Possible links between these results and the use of inhaled medication by individuals with COPD are discussed.

BACKGROUND: a comparative analysis of laboratory and instrumental tests at patients with bronchial obstructive diseases seems very actual due to the wide prevalence of these diseases. THE AIM: to evaluate characteristics of spirometry as well as allergic (total IgE, sputum eosinophils) and infectious (blood and sputum leucocytes, ESR, CRP, fibrinogen) inflammation markers at patients with bronchial obstructive diseases. PATIENTS AND METHODS: 104 case histories of patients with bronchial asthma, chronic obstructive pulmonary disease and overlap were analyzed including age, duration of smoking (pack-years), laboratory (clinical blood test, biochemical blood test, general sputum analysis, sputum culture) and instrumental (spirometry, body plethysmography, echocardiography) tests. Data were processed statistically with non-parametric methods. RESULTS: COPD patients were older than other groups’ patients, had the highest pack-years index. ACO patients were marked with maximal TLC and Raw, minimal FEV1, FEF25-75, FEV1/FVC. Patients with COPD had the highest inflammation markers (leucocyte count, CRP, fibrinogen). CONCLUSION: high active inflammation may cause severe lower airways possibility disorders at patients with COPD. Data related to a possible role of K. pneumoniaе in the pathogenesis of eosinophilic inflammation in lower airways are of significant interest. Patients with ACO occupy an intermediate position between asthma and COPD patients based on clinical and functional features.

Abstract Objective Chronic obstructive pulmonary disease (COPD) is a complicated multi-factor, multi-gene disease. Here, we aimed to assess the association of genetic polymorphisms in LINC01414/ LINC00824 and interactions with COPD susceptibility. Methods Three single nucleotide polymorphisms (SNPs) in LINC01414/LINC00824 was genotyped by Agena MassARRAY platform among 315 COPD patients and 314 controls. Logistic analysis adjusted by age and gender were applied to estimate the genetic contribution of selected SNPs to COPD susceptibility. Results LINC01414 rs699467 (OR = 0.73, 95% CI 0.56–0.94, p = 0.015) and LINC00824 rs7815944 (OR = 0.56, 95% CI 0.31–0.99, p = 0.046) might be protective factors for COPD occurrence, while LINC01414 rs298207 (OR = 2.88, 95% CI 1.31–6.31, p = 0.008) risk-allele was related to the increased risk of COPD in the whole population. Rs7815944 was associated with the reduced risk of COPD in the subjects aged > 70 years (OR = 0.29, p = 0.005). Rs6994670 (OR = 0.57, p = 0.007) contribute to a reduced COPD risk, while rs298207 (OR = 7.94, p = 0.009) was related to a higher susceptibility to COPD at age ≤ 70 years. Rs298207 (OR = 2.54, p = 0.043) and rs7815944 (OR = 0.43, p = 0.028) variants was associated COPD risk among males. Rs7815944 (OR = 0.16, p = 0.031) was related to the reduced susceptibility of COPD in former smokers. Moreover, the association between rs298207 genotype and COPD patients with dyspnea was found (OR = 0.50, p = 0.016), and rs7815944 was related to COPD patients with wheezing (OR = 0.22, p = 0.008). Conclusion Our finding provided further insights into LINC01414/LINC00824 polymorphisms at risk of COPD occurrence and accumulated evidence for the genetic susceptibility of COPD.
