Abstract

It has been reported that certain patients with non-small-cell lung cancer (NSCLC) that harbor activating somatic mutations within the tyrosine kinase domain of the epidermal growth factor receptor (EGFR) gene may be effectively treated using targeted therapy. The use of EGFR inhibitors in patient therapy has been demonstrated to improve response and survival rates; therefore, it was suggested that clinical screening for EGFR mutations should be performed for all patients. Numerous clinicopathological factors have been associated with EGFR and Kirsten-rat sarcoma oncogene homolog (KRAS) mutational status including gender, smoking history and histology. In addition, it was reported that EGFR mutation frequency in NSCLC patients was ethnicity-dependent, with an incidence rate of ~30% in Asian populations and ~15% in Caucasian populations. However, limited data has been reported on intra-ethnic differences throughout Europe. The present study aimed to investigate the frequency and spectrum of EGFR mutations in 1,472 Greek NSCLC patients. In addition, KRAS mutation analysis was performed in patients with known smoking history in order to determine the correlation of type and mutation frequency with smoking. High-resolution melting curve (HRM) analysis followed by Sanger sequencing was used to identify mutations in exons 18-21 of the EGFR gene and in exon 2 of the KRAS gene. A sensitive next-generation sequencing (NGS) technology was also employed to classify samples with equivocal results. The use of sensitive mutation detection techniques in a large study population of Greek NSCLC patients in routine diagnostic practice revealed an overall EGFR mutation frequency of 15.83%. This mutation frequency was comparable to that previously reported in other European populations. Of note, there was a 99.8% concordance between the HRM method and Sanger sequencing. NGS was found to be the most sensitive method. In addition, female non-smokers demonstrated a high prevalence of EGFR mutations. Furthermore, KRAS mutation analysis in patients with a known smoking history revealed no difference in mutation frequency according to smoking status; however, a different mutation spectrum was observed.

Abstract

Angiopoietin-2 (Ang-2) is an important mediator of angiogenesis and has been implicated in many inflammatory diseases. COPD is characterized by systemic inflammation, which is enhanced during exacerbations and may be assessed by measuring serum C-reactive protein (CRP). The aim of the study was to evaluate serum CRP and Ang-2 levels on the first (D1) and seventh day (D7) of hospitalization due to a COPD exacerbation and to examine possible associations of CRP and Ang-2 levels and kinetics with the length of hospital stay and outcome.We conducted a prospective study and evaluated 90 patients admitted to the hospital with a diagnosis of an acute exacerbation of COPD. A venous blood sample was obtained from all patients on D1 and D7 of hospitalization, for the measurement of Ang-2 and CRP.Serum Ang-2 levels were significantly higher on D1 compared to D7 during the course of COPD exacerbation (p0.001). Serum CRP levels were also significantly higher on D1 compared to D7 (p0.001). Serum Ang-2 presented a significant positive correlation with CRP levels both on D1 and D7 (r = 0.315 and r = 0.228, respectively). Patients with unfavorable outcome had significantly higher Ang-2 levels both on D1 (p = 0.04) and D7 (p = 0.01).Serum Ang-2 levels are elevated at the onset of COPD exacerbations and are positively associated with CRP levels. Ang-2 levels decrease during the course of COPD exacerbations in patients with favorable outcome. Serum Ang-2 may serve as a biomarker that could predict the outcome of a COPD exacerbation.

Abstract

Introduction: Chronic obstructive pulmonary disease (COPD) patients are at higher risk for pulmonary embolism (PE) due to limited mobility, smoking, inflammation or comorbidities. High D-dimer levels have been detected in many diseases including COPD exacerbation, even in the absence of detectable PE. Aims and Objectives: To determine the optimal D-dimer cutoff value for the diagnosis of PE, in patients hospitalized for COPD exacerbation. Methods: We retrospectively analyzed 180 consecutive patients, admitted to “KAA” and 5 th Respiratory Clinic of Athens Chest Hospital “Sotiria” for COPD exacerbation, according to Anthonisen criteria, during 2014. Fifty from the above patients were found to have been investigated with computed tomography angiography despite a low probability for PE (Wells score). All 50 patients had D-Dimer levels measured as well. Receiver operating characteristic (ROC) curve analysis was used to determine the accuracy of D-dimer measurements in diagnosing PE. Results: Fifty patients (72.1±12.0 years old) were included in the analysis. PE was detected in 10 patients (20%). D-dimer levels of COPD patients with PE (median value: 7655 mcg/L) were significantly higher than those of the patients without PE (median value: 940 mcg/L)(p Conclusions: Patients hospitalized for COPD exacerbation with low clinical probability for PE present D-dimer levels higher than normal, even without PE. The D-dimer cutoff value used to exclude PE should be adjusted, thus reducing the unnecessary use of diagnostic procedures.

During the 6-year study using the Centers for Disease Control and Prevention's (CDC) U.S. National Healthcare Safety Network (NHSN) definitions for device-associated health care-associated infection (DA-HAI), we collected prospective data from 605,310 patients hospitalized in the INICC's ICUs for an aggregate of 3,338,396 days. Although device utilization in the INICC's ICUs was similar to that reported from ICUs in the U.S. in the CDC's NHSN, rates of device-associated nosocomial infection were higher in the ICUs of the INICC hospitals: the pooled rate of central line-associated bloodstream infection in the INICC's ICUs, 4.9 per 1,000 central line days, is nearly 5-fold higher than the 0.9 per 1,000 central line days reported from comparable U. S. ICUs. The overall rate of ventilator-associated pneumonia was also higher (16.8 vs 1.1 per 1,000 ventilator days) as was the rate of catheter-associated urinary tract infection (5.5 vs 1.3 per 1,000 catheter days). Frequencies of resistance of Pseudomonas isolates to amikacin (42.8% vs 10%) and imipenem (42.4% vs 26.1%) and Klebsiella pneumoniae isolates to ceftazidime (71.2% vs 28.8%) and imipenem (19.6% vs 12.8%) were also higher in the INICC's ICUs compared with the ICUs of the CDC's NHSN.

Abstract

Background Asthma represents one of the most common medical conditions encountered during pregnancy, which occurs in 3 to 8 % of pregnant women [11. Namazy JA, Schatz M (2005) Pregnancy and asthma: recent developments. Curr Opin Pulm Med 11: 56-60. ]. Pregnancy may be associated with changes in the course of asthma, and asthma may affect the outcome of pregnancy. Although the incidence of severe asthma during pregnancy is low (0.4%-1.3%), its consequences on mother and fetus can be disastrous [22. Tan KS, Thompson NC (2000) Asthma in pregnancy. Am J Med 109: 727-733.]. Albeit small, significant increase in complications of pregnancy in asthmatic women such as perinatal mortality, pre-eclampsia, preterm deliveries or low birth weight infants are being registered [33. Grewal P, Mulla ZD, Simon MR (2008) Effect of Maternal Asthma on Pregnancy Outcomes: An Analysis of Texas Hospital Data. AEP 18: 735-736. ].

Abstract

Background: Several studies suggest that device-associated, health care-associated infections (DA-HAIs) affect the quality of care in intensive care units, increasing patients' morbidity and mortality and the costs of patient care. Objectives: To assess the DA-HAIs rates, microbiological profile, antimicrobial resistance, and crude excess mortality in 3 intensive care units in Athens, Greece. Methods: A prospective cohort, active DA-HAI surveillance study was conducted in 3 Greek intensive care units from July 2009 to June 2010. The rates of mechanical ventilator-associated pneumonia (VAP), central catheter-associated bloodstream infection (CLABSI), and catheter-associated urinary tract infection (CAUTI) were calculated along with microbiological profile, antimicrobial resistance, and crude excess mortality. Results: During 6004 days in intensive care, 152 of 294 patients acquired 205 DA-HAIs, an overall rate of 51.7% of patients or 34.1 DA-HAIs per 1000 days (95% CI, 29.3-38.6). The VAP rate was 20 (95% CI, 16.3-23.7) per 1000 ventilator-days, the CLABSI rate was 11.8 (95% CI: 9.2-14.8) per 1000 catheter-days, and the CAUTI rate was 4.2 (95% CI, 2.5-5.9) per 1000 catheter-days. The most frequently isolated pathogen was Acinetobacter baumannii among patients with CLABSI (37.8%) and Candida species among patients with CAUTI (66.7%). Excess mortality was 20.3% for VAP and CLABSI and 32.2% for carbapenem-resistant A baumannii CLABSI. Conclusion: High rates of DA-HAIs, device utilization, and anti -microbial resistance emphasize the need for antimicrobial stewardship, the establishment of an active surveillance program of DA-HAIs, and the implementation of evidence-based preventive strategies.

Abstract

The aim of this study was to investigate the impact of polymicrobial bloodstream infections (pBSIs) on the outcome of sepsis in an area where antimicrobial resistance is of concern. This was a retrospective analysis of data collected prospectively from patients developing BSI outside of an intensive care unit (non-ICU patients) or after ICU admission. Demographics and clinical characteristics were compared for patients with pBSI versus monomicrobial BSI (mBSI) and following stratification by ICU or non-ICU and severity of sepsis status. Possible risk factors for adverse outcome were explored by multivariate analysis, and outcomes were measured by Cox regression analysis. Among 412 patients with BSI, 47 patients (11.4%) with pBSI were recorded; compared with patients with mBSI, they had significantly higher APACHE II scores and presented more frequently with severe sepsis/septic shock. The all-cause 28-day mortality was significantly higher for pBSI versus mBSI (38.3% vs. 24.7%; P=0.033), whereas appropriateness of treatment was comparable (78.7% vs. 86.6%). Primary bacteraemia by combinations of Enterococcus faecalis, Klebsiella pneumoniae and Acinetobacter baumannii was predominant among pBSIs; in mBSIs, urinary tract infections by Escherichia coli, K. pneumoniae or Pseudomonas aeruginosa predominated. Multivariate analysis demonstrated pBSI as a significant contributor to 28-day mortality (HR=1.86; P=0.039), along with presence of two or more co-morbidities (HR=2.35; P=0.004). In conclusion, pBSIs differed epidemiologically from mBSIs, with the emergence of enterococcal species, and portended an almost two-fold increased risk of 28-day mortality. Prospective studies are warranted to elucidate possibly modifiable factors.

Abstract

Cytokines are key players in the biological processes of malignant tumors and special interest has been focused on cytokines exerting tumor and anti-tumor properties, such as vascular endothelial growth factor (VEGF) and Interleukin-18 (IL-18). Aim of this study was to assess IL-18 and VEGF levels in induced sputum of lung cancer patients at diagnosis, and assess their possible association with the histological type of cancer, the stage and the overall patient survival. Seventy six patients with a diagnosis of lung cancer were recruited and were followed up for 48months. Thirteen healthy smokers and 16 healthy non-smokers were used as control groups. VEGF and IL-18 were measured by ELISA in sputum supernatants at the time of diagnosis. Lung cancer patients had significantly higher baseline IL-18 and VEGF levels compared to healthy controls (p0.001). No difference was found in IL-18 and VEGF levels between the various stages in non-small cell lung cancer (NSCLC) and between limited and extended small cell lung cancer (SCLC). However, the ratio of VEGF/IL-18 was significantly higher in NSCLC compared to SCLC patients (p=0.018). In extended SCLC overall survival was inversely associated with baseline sputum VEGF levels (p=0.034) and estimated mortality risk was 1.14 (95% CI 1.006-1.283) for an increase of 100pg/ml in VEGF levels. Such association was not found regarding baseline IL-18 levels. VEGF levels in induced sputum may have a prognostic role in the survival of SCLC. The ratio VEGF/IL-18 in induced sputum differs between NSCLC and SCLC, indicating differences in angiogenesis mechanisms and/or immunological response in these two major histological types of lung cancer.
