Severity of chronic obstructive pulmonary disease (COPD) exacerbation is associated with increased level of copper (Cu), zinc
(Zn), and lipid peroxidation (malodialdehyde, MDA). The aim of this study was to investigate the levels of lipid peroxidation,
Coenzyme Q10 (CoQ10), Zn, and Cu in the COPD exacerbations. Forty-five patients with COPD acute exacerbation and 45 healthy
smokers as control group were used in the study. Forced expiratory volume in 1 s (FEV1) and forced vital capacity (FVC) were
lower in exacerbation group than in control. C- reactive protein levels, white blood cell count, and sedimentation rate were
significantly (p < 0.001) higher in patients than in control. CoQ10 level and Cu/Zn ratio was significantly (p < 0.05) lower in patients than in control, although MDA, Cu, and Zn levels were significantly (p < 0.05) higher in patients than in control. Negative correlations were found among MDA, Cu, Zn, FEV1, and FVC values in exacerbation
and control subjects (p < 0.05). In conclusion, we observed that oxidative stress in the exacerbation period of COPD patients was increased. The
decrease in CoQ10 level and Cu/Zn ratio and elevation in Cu and Zn levels observed in the patients probably result from the
defense response of organism and are mediated by inflammatory-like substances. 相似文献

Background
The present study aimed to examine the role of matrix metalloproteinase (MMP)‐3 [(–1171) 5A/6A; Lys45Glu (A/G)], MMP‐7 [(–181) A/G] and MMP‐12 [(–82) A/G; Asn357Ser (A/G)] variants in the development and severity of chronic obstructive pulmonary disease (COPD) in Tunisians.Methods
Plethysmography was performed in all participants to measure forced expiratory volume in 1 s (FEV1), forced vital capacity (FVC) and FEV1/FVC parameters. Genotyping of MMP‐3, MMP‐7 and MMP‐12 polymorphisms was carried out in 138 patients with COPD and 216 healthy controls using a polymerase chain reaction–restriction fragment length polymorphism. Serum levels of MMPs and cytokines (interleukin‐6, tumor necrosis factor‐α) were determined by an enzyme‐linked immunosorbent assay.Results
No significant correlations were observed between genetic variations in MMP‐3, MMP‐7 and MMP‐12 and the risk of development of COPD. Additionally, no impact of MMP‐7 (–181) A/G and MMP‐12 [(–82) A/G; Asn357Ser (A/G)] polymorphisms was observed on the respective protein levels and clinical parameters of the disease. Interestingly, both MMP‐3 (–1171) 5A/6A and Lys45Glu (A/G) variants were associated with respiratory function, as well as with serum levels of MMP‐3 in COPD patients. A relationship was found between the (–1171) 6A and 45Glu (G) alleles of the MMP‐3 gene and enhanced airflow limitation among COPD patients. Additionally, carriers of the 6A6A and 45 GG genotypes present higher MMP‐3 levels than noncarriers.Conclusions
MMP‐3 (–1171) 5A/6A and Lys45Glu (A/G) polymorphisms were associated with the decline of lung function among COPD patients. These results could be linked to the upregulation of MMP‐3 in serum from COPD patients carrying the (–1171) 6A and 45 G homozygous genotypes. 相似文献10.

The human α/β hydrolase domain-containing protein 2 gene (ABHD2) plays a critical role in pulmonary emphysema, a major subset of the clinical entity known as chronic obstructive pulmonary disease (COPD). Here, we evaluated genetic variation in the ABHD2 gene in a Chinese Han population of 286 COPD patients and 326 control subjects. The rs12442260 CT/CC genotype was associated with COPD (P < 0.001) under a dominant model. In the former-smoker group, the rs12442260 TT genotype was associated with a decreased risk of developing COPD after adjusting for age, gender and pack-years (P = 0.012). Rs12442260 was also associated with pre-FEV1 (the predicted bronchodilator forced expiratory volume in the first second) in controls (P = 0.027), but with FEV1/ forced vital capacity (FVC) ratios only in COPD patients (P = 0.012) under a dominant model. Results from the current study suggest that ABHD2 gene polymorphisms contribute to COPD susceptibility in the Chinese Han population. 相似文献

The purpose of this study was to investigate the effects of depression, anxiety and sleep disturbances on cognitive functions in chronic obstructive pulmonary disease (COPD) patients. In this prospective case-control study, demographic data, smoking history, depression, anxiety, sleep quality and cognitive status of 48 COPD patients and 36 healthy volunteers aged 40–90 years were recorded. The Beck depression inventory (BDI), the Beck anxiety inventory (BAI), and Pittsburgh Sleep Quality Index (PSQI) were used to assess depression, anxiety and sleep quality, respectively in COPD patients. Cognitive performance was studied by the mini-mental state examination. The mean age of patients with COPD was 65.3 ± 9.4 years, and disease duration was 9.6 ± 7.8 years. Male sex ratio, smoking, BDI score, BAI score, total PSQI score, sleep latency, sleep duration, average use of sleep aids and sleep disturbances in patients with COPD were significantly higher than the control group (p < 0.05). When cognitive impairment was compared by age, FVC, FEV, FEV/FVC, PEF values and smoking, no statistically significant relationship was found (p > 0.05). A statistically significant relationship was established between cognitive impairment and severity of disease, presence of anxiety, presence of depression and sleep quality. In our study, we found that sleep disorders, depression and anxiety comorbid with COPD increased cognitive impairment as well as the severity of disease. We believe that this finding is important in terms of reducing the risk of cognitive impairment, preventing misdiagnosis and treatment of the aforementioned comorbid diseases. 相似文献

Purpose: Sulfur mustard (SM) lung is a heterogeneous disease associated with abnormal inflammatory immune responses. The Th17/Treg axis imbalance is associated with the pathogenesis of chronic inflammatory pulmonary disease. We aimed to determine the distribution of different Th17 and Treg cells in patients with SM lung and chronic obstructive pulmonary disease (COPD) and evaluate the clinical implications in this homeostasis. Methods: In this analytical cross-sectional study, CD4?+?Foxp3+?Treg and CD4+?IL-17+?Th17 cells were measured in peripheral blood mononuclear cells (PBMCs) and transbronchial biopsy (TBB) samples of 15 SM-exposed patients, 12 COPD and 13 healthy controls (HCs). The potential correlation between the ratio of Th17/Tregs and lung function was evaluated with multivariate logistic regression (MLR) analysis. Results: The frequency of CD4?+?FoxP3+?Tregs and CD4?+?IL-17+?Th17 was increased ~1.7-fold (8.71/4.95) and ~2.7-fold (1.028/0.371) respectively, in the PBMC of SM patients compared with the health controls (p?<?0.001). The results indicated that there were increases in the frequency of Th17 and Tregs cells in the patients with COPD versus the HC, that is, ~2.6-fold (0.987/0.371) and ~1.4-fold (7.12/4.95), respectively; but they did not reach to SM level (p?≥?0.05). Moreover, in the TBB samples, the CD4?+?IL-17+?Th17 and CD4+?FoxP3+?Tregs numbers were significantly higher in SM and COPD patients than HC (p?<?0.05). The Th17 and Treg cells were inversely correlated with forced expiratory volume in 1s (FEV1%) (r?=??0.351, p =?0.001; r?=??0.344, p?=?0.021) and FEV1/FVC (r?=??0.44, p?=?0.001; r?=??0.302, p?=?0.011), respectively. Instead, positive correlations were found between Treg/Th17 ratios and forced FEV1%pred (r?=?0.156, p?=?0.007), as well as FEV1/FVC ratio (r?=?0.334, p?=?0.006).

Human β-defensin 2 (hBD-2) has antimicrobial activity and may play a role in airway mucosal defense, but studies have not yet examined its expression in lung tissue of patients with chronic obstructive pulmonary disease (COPD). Here we investigated hBD-2 levels in lung tissues of COPD patients and analyzed their correlations with IL-8, IL-1β, cigarette smoking and lung function in order to see whether the protein may be involved in pathogenesis of the disease. Peripheral lung tissue specimens were obtained from 51 patients who underwent lung resection for peripheral lung cancer: healthy non-smokers (n = 8), healthy current smokers (n = 7), non-smokers with COPD (n = 11), and current smokers with COPD (n = 25). RT-PCR and immunohistochemical staining were used to detect expression levels of hBD-2, IL-8 and IL-1β. Expression of hBD-2 mRNA was significantly higher in COPD patients than in healthy controls, and significantly higher in current smokers than in non-smokers (p < 0.05). Among healthy controls, hBD-2 mRNA levels were similar between current smokers and non-smokers. Immunohistochemistry showed hBD-2 protein to be expressed mainly in epithelia of distal bronchioles and its expression pattern among our patient groups mirrored that of the mRNA. IL-8 mRNA levels were significantly higher in COPD patients than in healthy controls (p < 0.05), while IL-1β mRNA levels did not differ significantly among the groups. Levels of hBD-2 mRNA positively correlated with levels of IL-8 mRNA (r = 0.545, p = 0.002), and negatively correlated with FEV1/FVC ratios and with predicted FEV1% values (r = −0.406, p = 0.011). Our results indicate that hBD-2 expression is elevated in distal airways of COPD patients and that it may be involved in pathogenesis of the disease. Our data implicate cigarette smoking as a factor that may elevate hBD-2 levels in lung tissues of COPD patients. 相似文献
