Cabbage and fermented vegetables: From death rate heterogeneity in countries to candidates for mitigation strategies of severe COVID-19

Large differences in COVID‐19 death rates exist between countries and between regions of the same country. Some very low death rate countries such as Eastern Asia, Central Europe, or the Balkans have a common feature of eating large quantities of fermented foods. Although biases exist when examining ecological studies, fermented vegetables or cabbage have been associated with low death rates in European countries. SARS‐CoV‐2 binds to its receptor, the angiotensin‐converting enzyme 2 (ACE2). As a result of SARS‐CoV‐2 binding, ACE2 downregulation enhances the angiotensin II receptor type 1 (AT₁R) axis associated with oxidative stress. This leads to insulin resistance as well as lung and endothelial damage, two severe outcomes of COVID‐19. The nuclear factor (erythroid‐derived 2)‐like 2 (Nrf2) is the most potent antioxidant in humans and can block in particular the AT₁R axis. Cabbage contains precursors of sulforaphane, the most active natural activator of Nrf2. Fermented vegetables contain many lactobacilli, which are also potent Nrf2 activators. Three examples are: kimchi in Korea, westernized foods, and the slum paradox. It is proposed that fermented cabbage is a proof‐of‐concept of dietary manipulations that may enhance Nrf2‐associated antioxidant effects, helpful in mitigating COVID‐19 severity.

Increased Red Cell Distribution Width Is Associated With Disease Severity in Hospitalized Adults With SARS-CoV-2 Infection: An Observational Multicentric Study

Background: There is an amenable need for clinically applicable biomarkers in patients with SARS-CoV-2 infection. Red Cell Distribution Width (RDW) has been recently suggested as a prognostic biomarker for COVID-19.

Methods: This was an observational study enrolling patients between February 26 and May 15 2020. We aimed to validate the association of the previously published RDW threshold of 14.5% with markers of disease progression and mortality.

Results: A total number of 193 hospitalized patients with COVID-19 were enrolled and analyzed. Median age was 61 years (95% CI: 58–64). Patients with baseline RDW ≥14.5% (n = 41, 19.2%) presented with more progressive disease compared to patients with baseline RDW <14.5% (n = 156, 80.8%) as indicated by significant differences in maximum FiO2% during hospitalization (median: 100, 95% CI: 45.2–100, vs. 35, 95% CI: 31–40, p = 0.0001, respectively). Values of RDW ≥14.5% were also strongly associated with increased risk of mortality (HR: 4.1, 95% CI: 0.88–19.23), (p = 0.02).

Conclusion: Our study provides evidence to support reproducibility and validity of a specified cut-off threshold of RDW as biomarker of disease severity and mortality in patients with COVID-19.

Dual Bronchodilator in the Era of Triple Therapy

Pharmacological medications used for the treatment of COPD patients have increased significantly. Long-acting bronchodilators have been recognized as the mainstay of the treatment of stable COPD, while ICS are usually added in patients with COPD who experience exacerbations, despite bronchodilator treatment. In the latest years, several studies have been published showing the beneficial effect of adding ICS on dual bronchodilation in patients suffering from more severe disease comparing triple therapy with several therapeutic regiments including dual bronchodilation and providing a message that this triple therapy might be more appropriate for COPD patients. However, not all COPD patients have a desirable response to ICS treatment while long-term ICS use in COPD is associated with several side effects. In this report, we aimed to provide a review of the current knowledge on the importance of dual bronchodilation on COPD patients and to compare its use with triple therapy, by covering a wide spectrum of topics. Finally, we propose an algorithm on performing treatment step up from dual bronchodilation to triple therapy and step down from triple to double bronchodilation considering the current evidence.

Primary care and COVID-19: cutting the Gordian knot - the Greek experience and algorithm

The novel human coronavirus that is now named severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is the cause of coronavirus disease 2019 (COVID-19). The disease is mild in most people (∼80%). During the COVID-19 pandemic, in many countries the crisis has quickly overwhelmed the capacities of healthcare systems, leading to major challenges in their ability to respond [1, 2]. In Greece, we managed to control the pandemic by eliminating the number of cases and by keeping mortality rates within acceptable limits. As of 4 July 2020, the National Public Health Organisation reported 3511 cases (55% male) with 192 deaths; 517 patients were hospitalised. 811 (23%) of the total cases were linked to travelling abroad, while 1933 (55.1%) were linked to exposure to a confirmed case. Following extended discussions with primary care physicians and after fully considering our experiences during hospital emergencies, these findings suggest that primary care in Greece may have played a key role in the management of suspected cases of SARS-CoV-2, perhaps relieving the referral hospitals from suspect and mild cases, and critically contributing to our success story during the pandemic.

The Greek experience reveals that harmonised collaboration among primary care, secondary facilities, designated hospitals and official authorities results in prompt and accurate management of the pandemic-related crisis of COVID-19https://bit.ly/3eSHVhG

Biologics in severe asthma: the overlap endotype - opportunities and challenges

INTRODUCTION

Patients with severe asthma experience a significant burden of symptoms, disease exacerbations and medication side-effects. Severe asthma interferes with the patients' quality of life and has high health-care costs. New targeted biologic therapies have improved the management of severe asthma by significantly reducing exacerbations and maintenance corticosteroid use, and also improving lung function and patient quality of life.

AREAS COVERED

Not all severe asthmatics are eligible for such therapies. Those with allergic and eosinophilic asthma, usually referred to as 'T2-high' asthma benefit from anti-IgE and anti-IL-5/5 R antibodies respectively, whereas some asthmatics are eligible for both: 'overlap' endotype. In this review, we present briefly the monoclonal antibodies that have been approved in the management of severe asthma and we focus on the 'overlap' endotype.

EXPERT OPINION

Since these therapies are costly, it is extremely important to choose the right treatment for the right patient especially in the 'overlapping' one. The decision is mainly based on the judgment of the clinician and is often driven by the most easily obtainable biomarker, thus the blood eosinophil count. Comorbidities, patient's input and administration frequency may aid the decision of choosing one over another biologic.

Investigation of the health effects on workers exposed to respirable crystalline silica during outdoor and underground construction projects

Chronic exposure of workers to powder containing crystalline silica (Silicon dioxide; SiO2) can lead to chronic lung diseases (lung cancer, silicosis, etc.). Aim of this study was to evaluate the exposure of Greek construction workers to SiO2 and describe their pulmonary function. The study involved 86 outdoor and underground workers. Medical and professional history was obtained, and breath samples were collected at morning hours through a mask for the determination of SiO2 levels. Pulmonary function tests, radiological examination and evaluation of radiographs were also performed. Pulmonary function examination showed that the majority of the workers were within normal range (61.4%) while the rest were diagnosed with mild (26.5%) and more severe impairment (7.24%). Working conditions (underground-outdoor) were statistically significantly related to the categorization of pulmonary function (P=0.038). During radiological examination, the type of working activity/ conditions (underground-outdoor) were statistically significantly related to the categorization of these findings (P=0.044). Of the 69 employees, 52 did not present findings (75.4%) and 5 were diagnosed with findings specific to occupational diseases (7.23%). Environmental exposure to respirable crystalline silica (RCS) was detected at 0.0125 mg/m3 in the workplace, which is not beyond the legal limits. Underground workers with more than 15 years of exposure to SiO2 are more likely to present chronic silicosis compared to the workers of outdoor activities.

EBC metabolomics for asthma severity

Asthma is a heterogeneous disease with diverse severity and represents a considerable socio-economic burden. Exhaled Breath Condensate (EBC) is a biofluid directly obtained from the airway lining fluid non-invasively. We attempted to discriminate severe from mild-to-moderate asthma using EBC metabolomics based on both NMR and UHPLC-MS techniques. 36 patients were included in this study (15 patients with severe and 21 with mild-to-moderate asthma). EBC was collected and analyzed using both NMR and UHPLC-MS techniques for possible metabolites. Using PLS and oPLS analysis for the UHPLC-MS data, no metabolite was found to be sufficient for the discrimination of asthma severity. However, when another PLS-regression model was applied five metabolites were found to discriminate severe from mild-to-moderate asthma. Amino-acid lysine was the only metabolite that discriminated the two study groups using NMR data (p= 0.04, t-test with Welch's correction, AUC 0.66). EBC is an easily available biofluid which directly represents the lower airways but difficult-to-use for metabolomic analysis. Our study presents some encouraging findings for the discrimination of asthma severity subgroups using EBC metabolomics but more well-designed studies with a higher number of patients need to be conducted.

Mepolizumab in Severe Eosinophilic Asthma: A 2-Year Follow-Up in Specialized Asthma Clinics in Greece: An Interim Analysis

INTRODUCTION

Mepolizumab is a monoclonal antibody against IL-5 for the treatment of severe eosinophilic asthma. The aim of the current study was to present a predesigned interim analysis of the data of patients who have completed 1 year of therapy with mepolizumab.

METHODS

This study is a prospective multicenter, noninterventional 2-year observational study and aims to describe the clinical benefit and safety profile of mepolizumab in patients with severe eosinophilic asthma.

RESULTS

Compared to the year preceding the initiation of treatment, the annual rate of exacerbations decreased significantly, from 4.3 ± 2.3 to 1.3 ± 1.8; p < 0.0001. Forty-two patients received maintenance dose of oral corticosteroids (OCS) at baseline. From these patients at the end of 1 year of therapy with mepolizumab, 17 patients (40%) had achieved OCS discontinuation. A reduction in the median dose of OCS was also achieved. After 1 year of treatment with mepolizumab, the asthma control test score significantly increased from 16.3 ± 3.7 to 21.2 ± 3.8 (p < 0.0001). This marked clinical improvement was paralleled by a significant reduction of blood eosinophil count. All patients showed a considerable improvement of airflow limitation. In respect to adverse events of treatment with mepolizumab, 19 patients (27%) were recorded to have at least one such occurrence during their 1-year treatment.

CONCLUSIONS

We have shown that in patients with severe eosinophilic asthma, 1 year of treatment with mepolizumab was safe, resulted in significant reduction of the annual exacerbation rate, reduction (or even discontinuation) of the needed dose of OCS, and improvements of asthma control and lung function.

Biological predictors of third-line treatment outcomes in patients with advanced non-small cell lung cancer

e21597

Background: The introduction of molecularly-guided targeted therapies and immunotherapy in routine oncology practice has led to significant survival increases in a subset of patients with advanced-stage non-small cell lung cancer (NSCLC). Nevertheless, the ultimate prognosis of these patients remains grim, and their overall therapeutic management challenging, particularly beyond the first-line treatment setting. We herein aimed to assess outcomes of third-line treatment in real-world patients with NSCLC, and to investigate potential correlations of clinicopathological and laboratory fearures with survival data. Methods: The medical records of 111 patients with advanced NSCLC, diagnosed and treated at the Oncology Unit of Sotiria Athens General Hospital between January 1, 2015 and December 31, 2018, were retrospectively reviewed. Eligible patients were those who had received more than two cycles of third-line treatment. Clinicopathological and laboratory features of patients, including baseline levels of complete blood count parameters evaluated immediately before administration of third-line therapy, were recorded and correlated with progression-free and overall survival. Results: The majority of patients had lung adenocarcinoma (54.1%) and stage IV disease (64,9%). Progression-free survival rates at 3 and 6 months were 59% and 20, respectively. Risk of disease progression was 35% lower in adenocarcinoma, as compared to other histological subtypes. Increased haematocrit and reduced white blood cell count levels were independently correlated with decreased risk of disease progression [HR (95% CI): 0,95(0,91-1,00); p = 0,044 and HR (95% CI):.1,05(1,00-1,11); p = 0,048, respectively]. Furthermore, higher white blood cell count and platelet count levels were independent predictors of decreased survival [HR (95% CI): 1,05 (1,01-1,1); p = 0,018 and HR (95% CI): 1,02(1-1,04); p = 0,018, respectively]. Conclusions: Haematocrit, white blood cell count and platelet count, recorded immediately before initiation of third-line therapy, may represent independent predictors of survival parameters in patients with advanced NSCLC.

The Economic Burden of Asthma in Greece: A Cross-Sectional Study

BACKGROUND

The high prevalence rates of asthma worldwide and the chronic nature of the disease make asthma a major cause of morbidity, imposing a significant socio-economic burden in many countries. Specifically in Greece, the self-reported prevalence of asthma reached 9% in 2017.

OBJECTIVES

The objective of this study was to estimate the total management cost of asthma in Greece and its potential determinants.

METHODS

A population-based, random-digit-dialed telephone nationwide survey was conducted to recruit patients with asthma in Greece (n = 353). A structured questionnaire was used to collect data on demographic and lifestyle characteristics, exacerbations, asthma control, medical resource utilization, and productivity loss during the past 12 months. The total annual direct cost from the societal, payer, and patient perspective as well as the indirect cost was calculated. All costs refer to the year 2017 (€). The significance level was set to α = 0.05.

RESULTS

The mean (95% confidence interval) annual total cost per patient for asthma management from the societal, payer, and patient perspective was €895 (696-1105), €673 (497-861), and €151 (119-188), respectively. The direct medical cost accounted for almost 90% of the total cost, whereas only 4% was attributed to the indirect cost. The direct medical cost was mainly driven by the medication cost (48%). The total annual societal cost was statistically significantly higher in those with not well-controlled asthma (p = 0.014) and those experiencing exacerbations during the past 12 months (p < 0.001) than in their counterparts. The total annual economic burden of asthma in Greece was estimated at €727 million and €547 million from the societal and payer perspective, respectively.

CONCLUSION

Our findings indicate that asthma imposes a high economic burden on society and the healthcare system in Greece. Therefore, greater investment in interventions aimed at asthma control and prevention of acute exacerbations may reduce the overall burden of asthma in Greece.

Inflammatory profile in optimally treated patients with adult versus early-onset asthma

Introduction: The age of asthma onset is often implicated in clinical manifestation, diagnosis, and management of the disease. Aim: To define demographic, clinical and functional features and inflammatory characteristics in induced sputum in patients with adult-onset asthma. Methods: Optimally treated patients from asthma clinics of two tertiary hospitals were included in the study. Patients underwent assessment of demographic characteristics, severity and treatment regimes, pulmonary function tests, and skin prick tests, as well as measurement of blood eosinophils and sputum induction for the assessment of sputum inflammatory cells, IL-8 and IL-13 levels in the supernatant. Results: Of the 333 patients recruited, 234 (70.2%) had adult-onset asthma. Adult-onset asthmatics were older, had a higher BMI, a shorter disease duration, and were less often atopic, compared to patients with early onset asthma. Higher proportions of patients with severe asthma presented increased levels of FeNO and blood eosinophils, both in the early and the adult-onset patient groups. Finally, obese patients with early onset asthma were characterized by less atopy compared to non-obese patients in the same group. Conclusion: Adult-onset asthma was characterized by less sputum eosinophilia, a nonatopic profile and a higher BMI compared to early-onset asthma. The presence of blood eosinophilia and increased FeNO in patients with severe asthma was comparable in the two groups.

Experimental and investigational phosphodiesterase inhibitors in development for asthma

INTRODUCTION

Severe, inadequately-controlled asthma remains a clinical challenge. For this reason, clinical trials and preclinical experimental studies on novel agents as an add-on therapies continue emerge. Phosphodiesterases (PDEs) are enzymes that regulate the function of immune cells by hydrolyzing cyclic guanosine monophosphate/cGMP and cyclic adenosine monophosphate/cAMP. PDEs are divided into subfamilies [PDE3, PDE4, PDE5 and PDE7] which are mainly found in the respiratory tract. Inhibitors of PDEs have already been approved for COPD and pulmonary hypertension.

AREAS COVERED

The role of PDE inhibitors in asthma treatment and the possible mechanism of action via their anti-inflammatory and/or bronchodilating effect are discussed.

EXPERT OPINION

Novel PDE inhibitors exhibiting fewer adverse events may have a role as add-on therapies in asthma treatment in the future. More clinical trials are necessary to prove their efficacy and evaluate their safety profile before approval by regulatory bodies is granted.

Spirometric Values of Greek People and Comparison with ECSC and GLI Values in COPD People

Background:

During the past few years, the use of criteria introduced by Global Initiative for Chronic Obstructive Lung Disease (GOLD) is recommended for the diagnosis and classification of Chronic Obstructive Pulmonary Disease(COPD),taking into account the values of a Forced Expiratory Volume In 1 second (FEV1) and a Forced Expiratory Volume In 1 second (FEV1) to Forced Vital Capacity (FVC) ratio. In Europe, the reference values of the European Coal and Steel Community (ECSC), that were originally developed in 1993 are still used.

Aim of the Study:

The study aimed to carry out measurement of spirometric values in a healthy, non smoking Greek population, development of local equations and comparison with ECSC and Global Lung Initiative(GLI) equations, in order to see if there is a need for separate ones in everyday use.

Methods:

Normal predicted values for FEV1 and FEV1/FVC% were obtained from a group of 500 healthy subjects, aged 18-89 years. In addition, a group of 124 COPD patients, with no other comorbidities was studied. Patients were classified according to GOLD criteria in four groups with ECSC, GLI predicted values or with our own predicted values.

Results:

The statistical analysis has revealed that there is no significant difference among the three sets of predicted values and no statistical difference was detected among the classification of COPD patients.

Conclusion:

It is shown that the 3 sets of predicted values are almost identical, despite the fact that they have been collected from different study populations.Αccording to the study, there is no need in recalculating values for Greek population.

Therapeutic effects of the combination of inhaled beta2-agonists and beta-blockers in COPD patients with cardiovascular disease

Chronic obstructive pulmonary disease (COPD) is a major health problem worldwide, with co-morbidities contributing to the overall severity and mortality of the disease. The incidence and prevalence of cardiovascular disease among COPD patients are high. Both disorders often co-exist, mainly due to smoking, but they also share common underlying risk factors, such as aging and low-grade systemic inflammation. The therapeutic approach is based on agents, whose pharmacological properties are completely opposed. Beta2-agonists remain the cornerstone of COPD treatment due to their limited cardiac adverse effects. On the other hand, beta-blockers are administered in COPD patients with cardiovascular disease, but despite their proven cardiac benefits, they remain underused. There is still a trend among physicians over underprescription of these drugs in patients with heart failure and COPD due to bronchoconstriction. Therefore, cardioselective beta-blockers are preferred, and recent meta-analyses have shown reduced rates in mortality and exacerbations in COPD patients treated with beta-blockers.

The self-reported prevalence and disease burden of asthma in Greece

OBJECTIVES

The primary objective was to estimate the self-reported prevalence of asthma in Greece. The secondary one was to assess the impact of asthma control on patients' health related Quality-of-Life (HRQoL), productivity loss, daily activities and psychological distress.

METHODS

A population-based, random-digit dialing, telephone nationwide survey was conducted to recruit patients with asthma. Among the responders, 3,946 met the age criterion (≥18 years) and completed the screening questions regarding asthma. Of them, 353 subjects reported that they had been diagnosed with asthma sometime in their life and completed the survey. Data on demographic and lifestyle characteristics, asthma control, comorbidities, limitations in daily activities, psychological distress, productivity loss, as well as HRQoL, were collected through telephone interview.

RESULTS

The lifetime self-reported prevalence of asthma was found to be 9.10% (95% CI:8.14%-9.94%). Sixty three percent of patients had well-controlled (WC) asthma. Asthma control was associated with gender, age, and specific comorbidities. Moreover, patients with not well-controlled (NWC) asthma were more likely to have missed work and reduced productivity during the past 12 months due to their asthma (p < 0.01). Patients with NWC asthma were more likely to declare psychological distress and limitations in their daily living activities. Patients' HRQoL with NWC asthma was significantly worse (0.65 ± 0.24) compared to those with WC asthma (0.86 ± 0.17, p ≤ 0.001).

CONCLUSIONS

The results of this survey revealed the link between the asthma control and burden of disease demonstrating the need for the implementation of programs aiming at the management of chronic symptoms related to this condition.

An algorithmic approach for the treatment of severe uncontrolled asthma

A small subgroup of patients with asthma suffers from severe disease that is either partially controlled or uncontrolled despite intensive, guideline-based treatment. These patients have significantly impaired quality of life and although they constitute <5% of all asthma patients, they are responsible for more than half of asthma-related healthcare costs. Here, we review a definition for severe asthma and present all therapeutic options currently available for these severe asthma patients. Moreover, we suggest a specific algorithmic treatment approach for the management of severe, difficult-to-treat asthma based on specific phenotype characteristics and biomarkers. The diagnosis and management of severe asthma requires specialised experience, time and effort to comprehend the needs and expectations of each individual patient and incorporate those as well as his/her specific phenotype characteristics into the management planning. Although some new treatment options are currently available for these patients, there is still a need for further research into severe asthma and yet more treatment options.
