Rhinovirus C

Background: Rhinovirus C is an important pathogen of asthmatic and non-asthmatic children hospitalised with episodic wheeze. Previous studies on other respiratory viruses have shown that several host cytokines correlate with duration of hospitalisation, but this has yet to be investigated in children with RV-C infection. We determined the nasal cytokine profiles of these children and investigated their relationship with RV-C load and clinical outcome. Flocked nasal swabs were collected from children aged 24–72 months presenting to the Emergency Department at Princess Margaret Hospital with a clinical diagnosis of acute wheeze and an acute upper respiratory tract viral infection. RV-C load was determined by quantitative RT-PCR and cytokine profiles were characterised by a commercial human cytokine 34-plex panel. RV-C was the most commonly detected virus in pre-school-aged children hospitalised with an episodic wheeze. RV-C load did not significantly differ between asthmatic and non-asthmatic patients. Both groups showed a Th2-based cytokine profile. However, Th17 response cytokines IL-17 and IL-1β were only elevated in RV-C-infected children with pre-existing asthma. Neither RV-C load nor any specific cytokines were associated illness severity in this study. Medically attended RV-C-induced wheeze is characterised by a Th2 inflammatory pattern, independent of viral load. Any therapeutic interventions should be aimed at modulating the host response following infection.

Asthma In Children

Background: Obese asthma is a complex syndrome with certain phenotypes that differ in children and adults. There is no clear evidence regarding the presence of additive or synergistic pathological interaction between obesity and asthma in children. Objectives: Our aim was to demonstrate the interaction of obesity and asthma in children in terms of airway and systemic inflammation by a controlled observational study. Methods: Four groups were formed: asthma obese (AO), asthma nonobese (ANO), non-AO (NAO), nonasthma nonobese (NANO). Spirometry test, fractional exhaled nitric oxide (FeNO) test, skin prick test, serum inflammatory biomarkers (C-reactive protein, C3, C4, adiponectin, leptin, resistin, periostin, YKL-40, Type 1, and Type 2 cytokines) were conducted and evaluated in all participants. Sputum inflammatory cells (sputum eosinophils and neutrophils) were evaluated in patients who could produce induced sputum and obesity-asthma interactions were determined. Results: A total of 153 participants aged 6–18 years were included in the study, including the AO group (n = 46), the ANO group (n = 45), the NAO group (n = 30), and the NANO group (n = 32). IL-4 (p < 0.001), IL-5 (p < 0.001), IL-13 (p < 0.001), resistin (p < 0.001), and YKL-40 (p < 0.001) levels were higher in patients with asthma independent of obesity. The lowest adiponectin level was found in the AO group and obesity-asthma interaction was detected (p < 0.001). Sputum eosinophilia (p < 0.01), sputum neutrophilia (p < 0.01), and FeNO levels (p = 0.07) were higher in asthmatic patients independent of obesity. In the group with paucigranulocytic inflammation, resistin and YKL-40 levels were significantly lower than in the group without paucigranulocytic inflammation (p < 0.01). Conclusion: No interaction was found between obesity and asthma in terms of airway inflammation. Interaction between obesity and asthma was shown in terms of adiponectin level and resistin/adiponectin and leptin/adiponectin ratios. It was found that serum YKL-40 and resistin levels could be associated with airway inflammation.

BACKGROUND: Asthma is a chronic airway disease which is characterized by oxidant antioxidant imbalance with the generation of oxidative stress related mediators.AIM: The study aimed to evaluate the role of asymmetric dimethylarginine, and malondialdehyde as oxidant markers and serum paraoxonase activity as an antioxidant marker in asthma, and to determine their relationship to the asthma severity and lung function among asthmatic children in Egypt.PATIENTS AND METHODS: This case control study was conducted on sixty patients with asthma compared with sixty apparently healthy children of matched age and sex.RESULTS: Serum concentrations of oxidant markers as asymmetric dimethylarginine and malondialdehyde were significantly increased in asthmatic patients while anti-oxidant marker as paraoxonase activity was significantly decreased compared to healthy controls (P < 0.05). ANOVA test revealed highly significant elevation of the serum concentrations of oxidant markers while anti-oxidant marker was significantly decreased in severe asthmatic patients (P < 0.001) compared to the patients with moderate and mild asthma respectively. Serum malondialdehyde concentration was a strong predictor of asthma severity by multiple regression analysis (P < 0.05).CONCLUSION: The study revealed an imbalance between oxidative and antioxidant defence systems in asthmatic children. Serum concentration of malondialdehyde was the most predictive biomarker having a significant association with asthma severity.

Bovine respiratory disease (BRD) results from interactions between pathogens, environmental stressors, and host factors. Obtaining a diagnosis of the causal pathogens is challenging but the use of high-throughput real-time PCR (rtPCR) may help target preventive and therapeutic interventions. The aim of this study was to improve the interpretation of rtPCR results by analysing their associations with clinical observations. The objective was to develop and illustrate a field-data driven statistical method to guide the selection of relevant quantification cycle cut-off values for pathogens associated with BRD for the high-throughput rtPCR system “Fluidigm BioMark HD” based on nasal swabs from calves. We used data from 36 herds enrolled in a Danish field study where 340 calves within pre-determined age-groups were subject to clinical examination and nasal swabs up to four times. The samples were analysed with the rtPCR system. Each of the 1,025 observation units were classified as sick with BRD or healthy, based on clinical scores. The optimal rtPCR results to predict BRD were investigated for Pasteurella multocida, Mycoplasma bovis, Histophilus somni, Mannheimia haemolytica, and Trueperella pyogenes by interpreting scatterplots and results of mixed effects logistic regression models. The clinically relevant rtPCR cut-off suggested for P. multocida and M. bovis was ≤ 21.3. For H. somni it was ≤ 17.4, while no cut-off could be determined for M. haemolytica and T. pyogenes. The demonstrated approach can provide objective support in the choice of clinically relevant cut-offs. However, for robust performance of the regression model sufficient amounts of suitable data are required.

Introduction. Previous studies have demonstrated the advantages of TCM use among asthmatic children. However, there is a paucity of epidemiologic reports on features of TCM users among asthmatic children. This cohort study aimed to investigate child’s, parent’s, and provider’s characteristics associated with the use of asthma-related TCM services among newly diagnosed asthmatic children.Materials and Methods. A nationally representative cohort of one million National Health Insurance beneficiaries was used. The newly diagnosed asthma children who received asthma medication from western medicine providers from 2005 to 2010 were selected as our sample for analysis. Generalized estimating equation was applied to identify the child’s, parents’, and provider’s characteristics associated with the use of asthma-related TCM among the newly diagnosed asthmatic children.Results. Of 20,080 children who were enrolled and followed up for one year, 4,034 children used TCM for asthma-related treatment. Children with prior experience of TCM, pre-school and school aged children, boys, those with more severe asthma or poorer health, with higher income parents were more likely to use asthma-related TCM. Herbal medicine was the most common modality among asthmatic children.Conclusions. There were only 20% newly diagnosed asthmatic children using TCM. The findings may shed light on possible integration of TCM with western medicine services.

Introduction: Asthma in children is one of the most common chronic diseases and little information available on factors associated with this disease in our part of the world. Objective:  The present study is an attempt to find out the socio-demographic and clinical profile of children with asthma. Methodology: This was a retrospective analysis of data of asthmatic children below 14 years attending pediatric chest clinic from July 2014 till March 2016. Results:  Of the 200 children, there were 142 (71%) males. The median age of presentation was 3 years and 139 (69.5%) from the age group 1-5years One third had poorly controlled asthma. Comorbidity was present in 59(29.5%) and allergic rhinitis (7%) was the most common. 90.5% had onset of wheezing before 5 years of age. Family history of asthma and/or atopy and smoking was present in 24% and 31%, respectively. 22% had exposure to pet animals. Upper respiratory tract infection (URTI) (37%) was the most common trigger for exacerbation. Cough (99%) and fast breathing (98%) were the most common symptoms. Conclusion: The majorities were males of young age with rhinitis as most common co-morbidity and many of them had a history of parental smoking at home. One third of them had poorly controlled asthma which shows the need for proper management of asthma including its comorbidity in younger children and changing certain habits like parental smoking at home.

Abstract Therapeutic interventions targeting viral infections remain a significant challenge for both the medical and scientific communities. While specific antiviral agents have shown success as therapeutics, viral resistance inevitably develops making many of these approaches ineffective. This inescapable obstacle warrants alternative approaches, such as targeting host cellular factors. Respiratory syncytial virus (RSV), the major respiratory pathogen of infants and children worldwide, causes respiratory tract infection ranging from mild upper respiratory tract symptoms to severe life-threatening lower respiratory tract disease. Despite the fact that the molecular biology of the virus, which was originally discovered in 1956, is well described, there is no vaccine or effective antiviral treatment against RSV infection. Here, we demonstrate that targeting host factors, specifically, mTOR signaling, limits RSV protein production and viral replication. Further, we show that this approach is generalizable as inhibition of mTOR kinases reduces coronavirus gene expression, protein production and replication. Overall, defining virus replication-dependent host functions may be an effective means to combat viral infections, particular in the absence of antiviral drugs.

BACKGROUND: Asthma is considered a chronic health illness that not only resulted in physical symptoms but also emotional effects. It is; therefore, so important to assess the quality of life of asthmatic patients besides their level of disease control. AIM: To determine the correlation of asthma control with the health-related quality of life (HRQOL) of asthmatic children in Egypt. METHODS: One hundred and twenty-eight asthmatic Egyptian children were enrolled in the study. They were subjected to asthma severity grading, asthma control questionnaire (ACQ) and pediatric asthma quality of life questionnaire (PAQLQ). Studied cases were taken from 6 primary and preparatory schools, Giza governorate. RESULTS: The mean child control score was significantly higher in not well-controlled asthmatics compared to well-controlled asthmatics (p < 0.005). The not well controlled asthmatic children showed significantly lower activity limitation score, symptoms score, and overall asthmatic score compared to controlled asthmatic children (p < 0.05). The severity of asthma shows significant positive correlation with symptoms score, emotional function score and overall asthmatic score (p < 0.05). CONCLUSION: The quality of life for the asthmatic children is strongly correlated with the level of asthma control and severity.

Abstract Introduction: Asthma is a chronic disease of the lower airways characterized by usually reversible airflow obstruction, inflammation, and hyperreactivity to various types of stimuli. It is one of the most common chronic respiratory diseases among children and adults, with an incidence of 300 million people worldwide. Objective: To evaluate the quality of the existent evidence in the literature in order to support the use of videogames and software-based programson asthmatic children and teenager’s knowledge capacity and self-management compared with standard education. Methods: Search, selection and analysis (starting March 2016) of all the original articles on virtual reality (VR) concerning asthmatic children and adolescents (ages 3 to 18), published up to October 2017, in Portuguese, English and Spanish, at the electronic databases Pubmed, Web of Science, MedlLine and LILACS, obtained by using the descriptors: asthma, video game, virtual reality, pulmonary rehabilitation, physical training. Results: Only six original articles were obtained. Of these, five (80%) presented level of evidence A, and one (20%) presented level of evidence B. All authors point out the treatment of asthma from VR as a safe and innovative therapy considering that the motivation and intensity of treatment from the use of VR improves the self-management capacity and aerobic capacity of asthmatic patients. Conclusion: The present study seeks to contribute to the literature by demonstrating that videogames and other software-based systemscan be used to improve knowledge capacity and self-management skills in children and teenagers with asthma diagnosis.

Introduction: The main aeroallergens present in house dust are the mites,Dermatophagoidespteronyssinus (Derp) andDermatophagoidesfarinae (Derf), and cockroaches,Periplanetaamericana (Pera). Objective: This work aims to genetically identify the allergens Derp, Derf, and Pera in household dust of asthmatic patients. Materials and methods: 29 patients, aged between 3 and 17 years, were classified as asthmatic or non-asthmatic according to the International Study of Asthma and Allergies in Childhood(ISAAC). Subjectscompleted a complementary questionnaire and skin hypersensitivity tests were performed. House dust was collected from these patients, filtered, and then DNA was extracted. Polymerase chain reactions were performed to identify Derp, Derf, and Pera in the samples. Results: There was an association between Pera sensitization and onset of asthma. There was also an association between the presence of Derp in the home of asthmatic patients and the worsening of symptoms, such as wheezing in the chest and allergic rhinitis. An association between the presence of Derf in house dust of asthmatic patients and the symptoms of allergic rhinitis was found. These data suggest that cockroach sensitization is a predominant factor in asthmatic children and the presence of mite allergens contributesto the worsening of asthma symptoms.
