Biseugenol Exhibited Anti-Inflammatory and Anti-Asthmatic Effects in an Asthma Mouse Model of Mixed-Granulocytic Asthma. Molecules 2020; 25:molecules25225384. [PMID: 33217892 PMCID: PMC7698799 DOI: 10.3390/molecules25225384] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/17/2020] [Revised: 09/21/2020] [Accepted: 09/24/2020] [Indexed: 11/16/2022] Open
Abstract
In the present work, the anti-inflammatory and antiasthmatic potential of biseugenol, isolated as the main component from n-hexane extract from leaves of Nectandra leucantha and chemically prepared using oxidative coupling from eugenol, was evaluated in an experimental model of mixed-granulocytic asthma. Initially, in silico studies of biseugenol showed good predictions for drug-likeness, with adherence to Lipinski’s rules of five (RO5), good Absorption, Distribution, Metabolism and Excretion (ADME) properties and no alerts for Pan-Assay Interference Compounds (PAINS), indicating adequate adherence to perform in vivo assays. Biseugenol (20 mg·kg−1) was thus administered intraperitoneally (four days of treatment) and resulted in a significant reduction in both eosinophils and neutrophils of bronchoalveolar lavage fluid in ovalbumin-sensitized mice with no statistical difference from dexamethasone (5 mg·kg−1). As for lung function parameters, biseugenol (20 mg·kg−1) significantly reduced airway and tissue damping in comparison to ovalbumin group, with similar efficacy to positive control dexamethasone. Airway hyperresponsiveness to intravenous methacholine was reduced with biseugenol but was inferior to dexamethasone in higher doses. In conclusion, biseugenol displayed antiasthmatic effects, as observed through the reduction of inflammation and airway hyperresponsiveness, with similar effects to dexamethasone, on mixed-granulocytic ovalbumin-sensitized mice.

[PMID: 32499881 PMCID: PMC7254431 DOI: 10.4081/ejtm.2019.8682] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/15/2019] [Accepted: 12/08/2019] [Indexed: 11/22/2022] Open
Abstract
Asthma has been known as a prevalent chronic-type inflammatory disease in children, because of their narrower respiratory airways. The present study aimed to identify guidelines for children asthma treatments. Extensive research was conducted on biomedical and pharmacological bibliographic database PubMed, EMBASE, MEDLINE, LILACS database, global independent network of Cochrane, Science Direct and global health library of Global Index Medicus. A comprehensive literature review was carried out using the terms Pediatric Asthma, epidemiology, management, and related clinical guidelines published from 2000 to 2019. After the primary assessment, quick diagnosis, clinical practice guidelines are useful tools for proper management of pediatric Asthma. By setting proper guidelines for this particular population, a higher improvement in quality of management of of pediatric Asthma is expected. Given the differences between the recommendations arisen by BTS/SIGN and NICE guidelines, critical comparison of the evidence-base guidelines provide suggestions that have more in common than what might seems at the first glance. The analysis of the variations presented in the present article will assist clinicians to make accurate decisions regarding their patients.

Abstract
Asthma is one of the leading chronic diseases in the pediatric population affecting 1 out of every 12 school-aged children. It has a significant contribution to the growing prevalence in prescribed medications. The symptoms of pediatric asthma are often variable. Pharmacotherapy is dominant modality in the treatment of asthma. Safe and effective treatment is still a challenge for all caregivers, including pharmacists. Taking into account the increasing global burden of asthma, pharmacists are ideally positioned to contribute in asthma management. The concept of pharmaceutical care implies achieving an optimal therapeutic outcome and improving patient’s quality of life through the promotion of rational drug use.
The aim of this article is to give an overview of published data emphasizing to the need of implementation of pharmaceutical care services in the treatment of childhood asthma and the significant aspects of pediatric asthma medication therapy management in community pharmacy.

Abstract
BACKGROUND Asthma exacerbation trajectories in children after incident asthma diagnosis are understudied. OBJECTIVE To identify trajectories of asthma exacerbation and predictors of these trajectories in children with incident asthma. METHODS Children from the National Longitudinal Survey of Children and Youth, Canada, with incident asthma were followed-up for up to 12 years during childhood. Latent class growth modeling was used to identify distinct asthma exacerbation trajectory groups. Multinomial logistic regression was performed to identify predictors of trajectory group membership. RESULTS The mean age at asthma diagnosis among 403 children was 5.9 years. Three distinct trajectories were identified: low increasing (21.3% of children), medium decreasing (45.8% of children), and high decreasing (32.8% of children). Asthma attack probability increased gradually after diagnosis in low increasing group, decreased from moderate level after diagnosis to almost zero probability at the end of follow-up in the medium decreasing group, and decreased after diagnosis but remained higher in the high decreasing group than the other 2 groups at 12 years after diagnosis. Children having more siblings at home were more likely to belong to the medium decreasing and high decreasing trajectory groups, whereas children older at asthma diagnosis were less likely to belong to the medium decreasing and high decreasing trajectory groups than the low increasing trajectory group. CONCLUSION Our results suggest that children with incident asthma follow 3 distinct trajectories of asthma exacerbations after asthma diagnosis. The trajectory group with initial moderate exacerbation probability has better long-term prognosis.

Abstract
Asthma is a heterogeneous disease comprising of multiple phenotypes and affects patients from childhood up to old age. In this review, we summarize the current knowledge on the similarities and differences in asthma across different age-groups, with emphasis on the perspective from primary care. Despite the similar disease presentation, phenotyping studies showed that there are differences in the distribution of phenotypes of asthma presenting in childhood compared to that in adulthood. Whereas, asthma with early age of onset tends to be of the atopic phenotype, the disease shifts toward the non-atopic phenotypes at later ages. Studies within primary care patients aiming to elucidate risk factors for future asthma exacerbation have shown pediatric and elderly patients to be at higher risk for future asthma attacks compared to other adult patients. Regardless, both pediatric and adult studies demonstrated previous asthma episodes and severity, along with high blood eosinophil to predict subsequent asthma attacks. Differences in childhood and adult asthma are not limited to the underlying phenotypes but also extends to the challenges in the diagnosis, treatment, and management of the disease. Diagnosis of asthma is complicated by age-specific differential diagnoses such as infectious wheezing and nasal obstruction in children, and aging-related problems such as heart disease and obesity in the elderly. There are also age-related issues leading to decreased disease control such as non-adherence, tobacco use, difficulty in using inhalers and corticosteroid-related side effects which hinder asthma control at different patient age-groups. Several clinical guidelines are available to guide the diagnosis and drug prescription of asthma in pediatric patients. However, there are conflicting recommendations for the diagnostic tools and treatment for pediatric patients, posing additional challenges for primary care physicians in working with multiple guidelines. While tools such as spirometry and peak flow variability are often available in primary care, their usage in preschool patients is not consistently recommended. FeNO measurement may be a valuable non-invasive tool which can be adopted by primary physicians to assist asthma diagnosis in preschool-age patients.

Abstract
BACKGROUND It has been documented that aerobic exercise may increase pulmonary functions and aerobic capacity, but limited data has evaluated a child's satisfaction and pediatric quality of life (PQoL) with exercise training. OBJECTIVES This study aimed to investigate the effects of moderate-intensity exercise training on asthmatic school-aged children. SUBJECTS AND METHODS This study included 38 school-aged children with asthma (23 males and 15 females) aged between 8-12 years. They were randomly assigned to two groups, aerobic exercise (AE) and conventional treatment (Con ttt) groups. The AE group received a program of moderate-intensity aerobic exercise for 10 weeks with asthma medications and the Con ttt group received only asthma medications without exercise intervention. A home respiratory exercise was recommended for the two groups. Aerobic capacity was investigated using maximal oxygen uptake (VO2max), 6-minute walk test (6MWT), and fatigue index. PQoL was evaluated using Pediatric Quality of Life Questionnaire (PQoLQ). Also, pulmonary function tests were performed, and the results recorded. RESULTS The findings of this study showed significant improvements in pulmonary functions and VO2max in the two groups; however, this improvement was significantly higher in the AE group than in the Con ttt group (p<0.05). The 6MWT and fatigue index improved in the AE group (p<0.05) but not in the Con ttt group (p>0.05). All dimensions of PQoL significantly improved in the AE group (p<0.05), but there was no significant improvement in the Con ttt group after the 10-week intervention period (p>0.05). CONCLUSION Ten weeks of physical exercise had beneficial effects on pulmonary functions, aerobic capacity, and PQoL in school-aged children with asthma. Effort and awareness should be dedicated to encouraging the active lifestyle among different populations, especially asthmatic children.

Abstract
BACKGROUND This study aims to explore the relationship between serum vitamin A and 25-hydroxyvitamin D3 (25OHD3) levels with pulmonary function and quality of life (QOL) in children with stable asthma. METHODS A total of 117 cases of children with stable asthma were assigned into the case group and 129 healthy children underwent physical examination during the same period into the control group. Electrochemiluminescence was employed to determine serum vitamin A and 25OHD3 levels. The children with stable asthma were further divided into the mild, moderate, and severe groups according to their degree of asthma. A pulmonary function meter was used to assess the pulmonary function indexes: percentage of forced expiratory volume in 1 sec/predictive value (FEV1%pred), forced vital capacity (FVC), forced expiratory volume in 1 sec/forced vital capacity (FEV1/FVC), peak expiratory flow (PEF), and maximal voluntary ventilation (MVV). The children's quality (QOL) of life with asthma was evaluated by their activities of daily living (ADLs) and Medical Research Council (MRC) scores. Pearson correlation analysis was applied to analyze the correlations of serum vitamin A and 25OHD3 levels with FEV1%pred, FVC, FEV1/FVC, PEF, MVV, ADL, and MRC. RESULTS Serum vitamin A and 25OHD3 levels were lower in children with stable asthma than those who were in the control group (P < .05). The severe group showed the lowest FEV1%pred, FVC, FEV1/FVC, PEF, MVV, and ADL scores, and the highest MRC score compared to the mild and moderate groups (all P < .05). Serum vitamin A and 25OHD3 levels were positively correlated with pulmonary function and ADL score in children with stable asthma, while serum vitamin A and 25OHD3 levels were negatively correlated with MRC score (all P < .05). In the case group, serum vitamin A and 25OHD3 levels were positively correlated with serum calcium and phosphorus levels (all P < .05). CONCLUSION These findings indicate that increased serum vitamin A and 25OHD3 levels reflect good pulmonary function and good QOL in children with stable asthma.

Acute Asthma in the Pediatric Emergency Department: Infections Are the Main Triggers of Exacerbations. BIOMED RESEARCH INTERNATIONAL 2017; 2017:9687061. [PMID: 29159184 PMCID: PMC5660758 DOI: 10.1155/2017/9687061] [Citation(s) in RCA: 16] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 06/15/2017] [Revised: 08/21/2017] [Accepted: 08/29/2017] [Indexed: 01/13/2023]
Abstract
Background Asthma exacerbations are a common reason for Emergency Department (ED) visits in children. Aim To analyze differences among age groups in terms of triggering factors and seasonality and to identify those with higher risk of severe exacerbations. Methods We retrospectively revised the files of children admitted for acute asthma in 2016 in our Pediatric ED. Results Visits for acute asthma were 603/23197 (2.6%). 76% of the patients were <6 years old and 24% ≥6. Infections were the main trigger of exacerbations in both groups; 33% of the school-aged children had a triggering allergic condition (versus 3% in <6 years; p < .01). 191 patients had a previous history of asthma; among them, 95 were ≥6 years, 67% of whom were not using any controller medication, showing a higher risk of a moderate-to-severe exacerbation than those under long-term therapy (p < .01). Exacerbations peaked in autumn and winter in preschoolers and in spring and early autumn in the school-aged children. Conclusions Infections are the main trigger of acute asthma in children of any age, followed by allergy in the school-aged children. Efforts for an improved management of patients affected by chronic asthma might go through individualized action plans and possibly vaccinations and allergen-avoidance measures.

Abstract
Evidence-based practice is an important component of health care service delivery. However, there is a tendency, embodied in tools such as Grades of Recommendation, Assessment, Development, and Evaluation, to focus principally on the classification of study design, at the expense of a detailed assessment of the strengths and limitations of the individual study. Randomized controlled trials (RCTs), and in particular the classical “explanatory” RCT, have a privileged place in the hierarchy of evidence. However, classical RCTs have substantial limitations, most notably a lack of generalizability, which limit their direct applicability to clinical practice implementation. Pragmatic and observational studies can provide an invaluable perspective into real-world applicability. This evidence could be used more widely to complement ideal-condition results from classical RCTs, following the principle of triangulation. In this review article, we discuss several types of pragmatic and observational studies that could be used in this capacity. We discuss their particular strengths and how their limitations may be overcome and provide real-life examples by means of illustration.
