We studied activation of hemostatic reactions together with mechanisms of systemic inflammation and genetic factors responsible for thrombogenic risk in 65 patients suffering exacerbation of chronic obstructive pulmonary disease with 2 or 3 positive criteria proposed by N.Anthonisen at al. (1987). The levels of indicators of systemic inflammation, such as C-reactive protein and tumour necrosis factor-alpha, increased concurrently with those of homocysteine, endothelin-1, Willebrand factor plasminogen activator inhibitor type 1, and thrombin-antithrombin complex (marker of thrombinemia)...

OBJECTIVE: We reported association of haplotypes formed by IL-1b (IL1B)-511C/T (rs16944) and a variable number of tandem repeats (rs2234663) in intron 3 of IL-1 receptor antagonist (IL1RN) with rate of lung function decline in smoking-induced COPD. The aim of current study was to further investigate this association. METHODS: We genotyped an additional 19 polymorphisms in IL1 cluster (including IL1A, IL1B and IL1RN) in non-Hispanic whites who had the fastest (n = 268) and the slowest (n = 292) decline of FEV1% predicted in the same study...

BACKGROUND: Acute exacerbations represent a significant burden for patients with moderate-to-severe chronic obstructive pulmonary disease. Each exacerbation episode is frequently associated with a lengthy recovery and impaired quality of life. Prognostic factors for outpatients that may predict poor outcome after treatment with antibiotics recommended in the guidelines, are not fully understood. We aimed to identify pretherapy factors predictive of clinical failure in elderly (≥60 years old) outpatients with acute Anthonisen type 1 exacerbations...

Resistance to cephalosporins in Haemophilus influenzae is usually caused by characteristic alterations in penicillin-binding protein 3 (PBP3), encoded by the ftsI gene. Resistance to extended-spectrum cephalosporins is associated with high-level PBP3-mediated resistance (high-rPBP3), defined by the second stage S385T substitution in addition to a first stage substitution (R517H or N526K). The third stage L389F substitution is present in some high-rPBP3 strains. High-rPBP3 H. influenzae are considered rare outside Japan and Korea...

COPD Exacerbation RiskSESSION TYPE: Original Investigation SlidePRESENTED ON: Wednesday, October 29, 2014 at 02:45 PM - 04:15 PMPURPOSE: Prior data suggested that among Anthonisen criteria only an increase in sputum purulence was a predictor of clinical failure among mild to moderate COPD outpatients who did not receive antibiotics. In addition the use of a point-of-care C-reactive protein (CRP) test (cutoff > 40 mg/L) significantly increased the predictive accuracy of failure. However, limited data are available regarding the translation of these findings among hospitalized acutely exacerbated COPD (AECOPD) patients who did not receive antibiotics...

In the last decade, numerous papers have discussed what has been called the indiscriminate use of intermittent positive pressure breathing therapy (IPPB) for the treatment of obstructive airways disease (Curtis et al., 1968; Loke and Anthonisen, 1974; Cheney et al., 1976; Baker, 1974; Murray, 1974; Barach and Segal, 1975; Sheldon and Gold, 1976; Dolovich et al., 1977). These papers have all failed to show any advantage of positive pressure breathing therapy, either in the acute or chronic stages of obstructive airways disease...

BACKGROUND: Bacteria and viruses are major causes of chronic obstructive pulmonary disease (COPD) exacerbations. Molecular components of these pathogens are recognized by pattern-recognition receptors (PRRs) expressed by various cells in the airway, which leads to initiation of inflammatory processes. Expression levels of PRRs in airway inflammatory cells are expected to affect susceptibility to COPD exacerbation. AIMS: This prospective observational study was conducted to detect any association between exacerbation and PRR expression...

BACKGROUND: Beta-lactam resistance in Haemophilus influenzae due to ftsI mutations causing altered penicillin-binding protein 3 (PBP3) is increasing worldwide. Low-level resistant isolates with the N526K substitution (group II low-rPBP3) predominate in most geographical regions, while high-level resistant isolates with the additional S385T substitution (group III high-rPBP3) are common in Japan and South Korea.Knowledge about the molecular epidemiology of rPBP3 strains is limited. We combined multilocus sequence typing (MLST) and ftsI/PBP3 typing to study the emergence and spread of rPBP3 in nontypeable H...

Abstract Bacterial infection is a major cause of acute exacerbations of chronic obstructive pulmonary disease (AECOPD), which are associated with significantly increased airway and systemic inflammation. However, the relationship among bacteriology, the resolution of inflammation and clinical outcomes is largely unknown. In this study, we recruited consecutive patients hospitalized for AECOPD with purulent sputum. We measured the airway and systemic inflammation levels, the COPD assessment test (CAT) score and adverse outcomes between patients with and without potentially pathogenic microorganisms (PPM)...

In March 2012, a second outbreak of Cryptosporidium parvum affected children following a stay at a holiday farm in Norway; the first outbreak occurred in 2009. We studied a cohort of 145 schoolchildren who had visited the farm, of which 40 (28%) were cases. Cryptosporidium oocysts were detected in faecal samples from humans, goat kids and lambs. Molecular studies revealed C. parvum subtype IIa A19G1R1 in all samples including human samples from the 2009 outbreak. A dose-response relationship was found between the number of optional sessions with animals and illness, increasing from two sessions [risk ratio (RR) 2·7, 95% confidence interval (CI) 0·6-11·5] to six sessions (RR 8·0, 95% CI 1·7-37·7)...

BACKGROUND: Anthonisen criteria are widely used to guide the use of antibiotics in exacerbations of COPD. We evaluated the best predictors of outcomes in exacerbations of mild to moderate COPD not treated with antibiotics. METHODS: We used data from 152 patients of the placebo arm of a randomized trial of amoxicillin/clavulanate for exacerbations of mild to moderate COPD. Clinical response in relation to Anthonisen criteria and point-of-care serum C-reactive protein (CRP) tests (cutoff, 40 mg/L) was assessed with multivariate logistic regression analysis...

Myeloperoxidase is a strong oxidant stored in primary granules of neutrophils with potent antibacterial and proatherogenic properties. Myeloperoxidase has been implicated in the pathogenesis of chronic obstructive pulmonary disease (COPD). However, the relationship of myeloperoxidase to health outcomes in COPD is not well known. We measured serum myeloperoxidase levels from 4,677 subjects with mild to moderate airflow limitation in the Lung Health Study. Using a Cox proportional hazards model, we determined the relationship of serum myeloperoxidase concentration to the risk of all-cause and disease specific causes of mortality...

BACKGROUND: Paper-based diaries and self-report of symptom worsening in COPD may lead to underdetection of exacerbations. Epidemiologically, COPD exacerbations exhibit seasonal patterns peaking at year-end. We examined whether the use of a BlackBerry-based daily symptom diary would detect 95% or more of exacerbations and enable characterization of seasonal differences among them. METHODS: Fifty participants with GOLD (Global Initiative for Chronic Obstructive Lung Disease) stage I to IV COPD began a community-based study in December 2007...

BACKGROUND: Acute exacerbations of chronic bronchitis (AECB), including chronic obstructive pulmonary disease (AECOPD), represent a substantial patient burden. Few data exist on outpatient antibiotic management for AECB/AECOPD in Eastern/South Eastern Europe, in particular on the use of moxifloxacin (Avelox®), although moxifloxacin is widely approved in this region based on evidence from international clinical studies. METHODS: AVANTI (AVelox® in Acute Exacerbations of chroNic bronchiTIs) was a prospective, observational study conducted in eight Eastern European countries in patients > 35 years with AECB/AECOPD to whom moxifloxacin was prescribed...

An oxidant-antioxidant imbalance in the lung contributes to the development of chronic obstructive pulmonary disease (COPD) that is caused by a complex interaction of genetic and environmental risk factors. Nuclear erythroid 2-related factor 2 (NFE2L2 or NRF2) is a critical molecule in the lung's defense mechanism against oxidants. We investigated whether polymorphisms in the NFE2L2 pathway affected the rate of decline of lung function in smokers from the Lung Health Study (LHS)(n = 547) and in a replication set, the Vlagtwedde-Vlaardingen cohort (n = 533)...
