Effects of ADRB2 gene regulatory region polymorphism on the efficacy of SABA in the treatment of acute asthma attack in children / 中国药房

OBJECTIVE To explore the effects of ADRB2 gene regulatory region polymorphism on the efficacy of short-acting beta 2 receptor agonists （SABA） in the treatment of acute asthma attack in children. METHODS A total of 127 children with acute mild to moderate bronchial asthma who received SABA treatment for 7 days in the General Hospital of Northern Theater Command from October 2016 to October 2020 were selected to detect their genotype distribution and compare the improvement of pulmonary functional indicators and curative effect among different genotypes. The effect of the high-order interaction of gene polymorphism on therapeutic effect was investigated. RESULTS Among 127 children， there were 80， 44 and 3 cases of TT， TA and AA types at locus rs2895795， 93， 32 and 2 cases of CC， CG and GG types at locus rs11168070， and 41， 64 and 22 cases of GG， GA and AA types at locus rs12654778， respectively， in accordance with Hardy-Weinberg equilibrium （P＞0.05）. After treatment， the improvement rate of the peak expiratory flow in percent predicted value （PEF%pred） and the improvement rate of the forced expiratory flow at 75% vital capacity in percent predicted value （FEF75%pred） in children with TA type were significantly lower than that of TT type at locus rs2895795 （P＜0.05）； the improvement rates of PEF%pred and FEF75%pred in children with CG type were significantly lower than that of CC type at locus rs11168070 （P＜0.05）； the improvement rates of PEF%pred in children with GA and AA type were significantly lower than that of GG type at locus rs12654778 （P＜0.05）. The differences in fractional exhaled nitric oxide before and after treatment were not statistically significant among different genotypes at each locus （P＞0.05）. The proportion of remarkable improvement of children with TT type at locus rs2895795 was 2.358 times that of children with TA+ AA type （P＜0.05）， and there was no significant effect of higher-order interaction of ADRB2 polymorphism on the efficacy in children with asthma （P＞0.05）. CONCLUSIONS Polymorphisms in the regulatory region of the ADRB2 gene in children with bronchial asthma are associated with the efficacy of SABA in the treatment of acute asthma attack in children. At locus rs2895795， rs11168070 and rs12654778， the improvement of lung function of children with wild-type is more obvious， and the efficacy of SABA treatment on children with TT type is better at locus rs2895795.

Asthma Attacks in Children—Challenges and Opportunities

Asthma is the most common chronic disease of childhood worldwide, and is responsible for signifcant morbidity and mortality in children and young people (CYP). Given the inherent dangers of a child experiencing even a single asthma attack, it is essential to identify and manage modifable risk factors at every clinical opportunity. Following an attack, there is an opportunity to prevent future attacks by assessing compliance and optimizing asthma control. Careful questioning will allow physicians to identify asthma triggers, barriers to good asthma control, and health beliefs or socioeconomic obstacles that may have contributed to this attack. The vast majority of children with asthma can achieve good symptom control with appropriate use of low-dose inhaled corticosteroids.

Sinicization of the Pediatric Respiratory Assessment Measure and test its reliability and validity / 中国实用护理杂志

Objective:To translate the Pediatric Respiratory Assessment Measure into Chinese, and to test its reliability and validity.Methods:According to the Brislin translation model, the English version of Pediatric Respiratory Assessment Measure was translated into Chinese, and then was back-translated and modified for cultural adaptation. From June 2019 to December 2020, convenience sampling method was used to evaluate the severity of 50 children with acute attack of bronchial asthma aged 2-14 years in the Affiliated Huaian No.1 People′s Hospital of Nanjing Medical University, in order to evaluate its reliability and validity.Results:The Cronbach α of the Chinese version of Pediatric Respiratory Assessment Measure was 0.838, the inter-rater reliability was 0.984; the average scale-content validity index was 0.97. One common factor was extracted, the cumulative variance contribution rate of superior sternal fossa depression was 61.83%. The criterion related validity between the evaluation results of doctors, nurses, respiratory therapists and the grading standard of bronchial asthma severity in the " Guidelines for the diagnosis, prevention and treatment of bronchial asthma in children ( 2016 edition)" were 0.903, 0.884 and 0.889, the ROC curve of the scale was 0.867 (95% CI 0.754-0.980). Conclusions:The Chinese version of Pediatric Respiratory Assessment Measure has good reliability and validity, which can be used to evaluate the severity of acute attack of bronchial asthma in children aged 2-14 in China, and provide a basis for further diagnosis and treatment.

The therapeutic effect of budesonide on childhood asthma and its influence on growth and development 1 to 2 years after the treatment / 药学实践杂志

Objective To explore the effect of budesonide suspension for inhalation in the treatment of childhood asthma and its influence on growth and development in 1-2 years. Methods The 68 children with asthma admitted to our hospital from October 2016 to January 2017 were selected. Every patient had acute attacks and received continued medication. 34 patients treated with salbutamol sulfate inhaled aerosol were used as the control group. 34 patients treated with budesonide suspension combined with salbutamol sulfate aerosol were classified as the observation group. The interleukin-6 (IL-6), tumor necrosis factor-α(TNF-α), high-sensitivity-C-reactive protein (hs-CRP), maximum respiratory flow, IS maximum expiratory volume, regulatory B cell ratio, wheezing disappearance time, shortness of breath relief time, wet rales disappearing time, cough disappearing time, and the two year follow-up indicators of growth and development were compared. Results After medication, IL-6, TNF-α, hs-CRP, regulatory B cell ratio, wheezing disappearance time, shortness of breath relief time, moist rales disappearance time, and cough disappearance time were lower in the observation group(P<0.05). The maximum respiratory flow and IS maximum expiratory volume in the observation group were higher than those in the control group (P<0.05). The GH level, height, and weight obtained from two year follow up in the observation group were lower than those in the control group (P<0.05). Conclusion Budesonide suspension combined with salbutamol sulfate aerosol inhalation therapy can alleviate the inflammatory reaction, improve the lung function and immune function of children, and accelerate the disappearance of clinical symptoms, but it will affect the growth and development of children to a certain extent.

Direct Costs of Hospitalized Acute Asthma in a Public Hospital of the City of Buenos Aires

There is little information about direct costs of acute asthma hospitalization in our country. This study was conducted for the purpose of determining such costs in a public hospital of the city of Buenos Aires. Clinical records of adult patients with acute asthma admitted to the Hospital General de Agudos Dr. J. M. Ramos Mejía of the city of Buenos Aires during 2016 were reviewed. The study determined direct costs from the funder's perspective, according to the resource allocation of the Government of the City of Buenos Aires for hospitalizations as of January 2018. The cost was informed in American dollars given the variation of the peso/dollar relationship, taking into account the exchange parity of January 2018. 25 hospital admissions of 20 patients were reviewed ; age 49 years old (median, 25-75% IQR, 36.5-62 years); 56% female; smokers (20% ex-smokers and 30% current smokers). Ten patients (50%) had had severe exacerbations the previous year. Only 10% of the patients adhered to previous preventive treatment, including the use of β2 agonists the previous month, 2.55 aerosols per patient (25-75% IQR, 2-3). The length of hospital stay was 7 days (median, 25-75% IQR, 4-10) in patient rooms and 14 days in the Intensive Care Unit. The total direct cost was 1,853 dollars per each hospitalization (median, 25-75% IQR, 1,393-2,654) in patient rooms and 6,361 dollars for the Intensive Care Unit. This is the first study in the country to deal with the direct costs of acute asthma hospitalization in a public hospital of Buenos Aires. Taking into consideration the low adherence rate to preventive treatment, we understand that a health system based on asthma management programs reduces and saves costs that could be used in many different ways within public health.

The effect of short-term particular matter(2.5) exposure on asthma attacks in asthma children in Fukuoka, Japan / 고신대학교의과대학학술지

OBJECTIVES: We investigated whether asthma attacks in asthmatic children were caused by short-term exposure to particulate matter(PM)2.5. METHODS: Subjects were 411 patients who received inhalation therapy in National Fukuoka Hospital, from March to May 2013. All subjects were outpatients. We surveyed the air quality measurement results in the stations closest to the address of the patients. Data were used from the City of Fukuoka website data on air pollution. We carried out a case-crossover study and compared PM2.5 concentration between 7 days after asthma attack occurred and the day asthma attack occurred and 1, 2 and 3 days before asthma attack occurred. RESULTS: Highest hourly concentration of the day (OR 1.013, 95%CI 1.000–1.025) showed a significant association with 1 day before PM2.5 concentration statistically. And 0–1 year-old infants were more vulnerable to the highest concentration of 1 day before PM2.5 concentration(P < 0.05). Average concentration of NO2 and O3 and asthma attack also showed a significant association. CONCLUSIONS: Maximal daily PM2.5 concentrations within 24 hours prior to the attack affect asthma exacerbation. 0–1 year-old infants are particularly vulnerable to PM2.5 concentration. Asthma exacerbation is aggravated by NO2 and O3 concentration on the day of the asthma attack.

Abnormal suppressive capacity of regulatory T cells to Th17 and Th9 cells in asthmatic patients / 中国免疫学杂志

Objective:To study the abnormal suppressive capacity of regulatory T cells ( Tregs) to effector cells,Th17 cells and Th9 cells in patients with mild to moderate asthma attack.Methods: Recruited asthmatic patients (n=30) and healthy control (n=30),collected peripheral venous blood from healthy control and asthmatic patients in mild to moderate attack stage respectively,and then isolated CD4+CD25+CD127-/low Tregs and CD4+CD25-T effect cells with immunomagnetic beads method ( purity was above 90%).The effect cells were cultured with PHA stimulation with or without Tregs.Measured the proliferation (3H-Thymidine), expression of RORC and PU.1 ( RT-PCR) genes,production of IL-17 and IL-9 ( LUMNEX) in effect cells with or without Tregs inter-vention.Analyzed the abnormality of Th17 and Th9 cells and the supressive capacity of Tregs on Th17 and Th9 cells in patients with asthma attack,comparing with control group.Results:Tregs of asthmatic patients could suppress the proliferation of effector cells,but less effectively than healthy control (P=0.03).In asthmatic patients,RORC expression and IL-17 production increased (P0.05).Conclusion:The suppressive capacity and amount of Tregs decreased,but the specific gene expression and cytokines production of Th17 cells and Th9 cells were upregulated in patients with mild to moderate asthma attack.This deficiency for the suppressive capacity of Tregs to Th17 but not Th9 cells may indicate some pathogenesis of asthma devel-opment.

The Finnish Allergy Programme 2008-2018

There are no nationwide, comprehensive public health programmes on allergic disorders with set goals and systematic follow-up. The Finnish initiative is based on the idea that the so called allergy epidemic in modern, urban societies is caused by inadequately developed or broken tolerance. The immune system is not trained to make the difference between danger and non-danger (allergy) or the difference between self and non-self (autoimmune diseases). The immune dysfunction leads to inappropriate inflammatory responses and clinical symptoms. The 10-year implementation programme is aimed to reduce burden of allergies both at the individual and societal levels. This is done by increasing both immunological and psychological tolerance and changing attitudes to support health instead of medicalising common and mild allergy symptoms. Severe forms of allergy are in special focus, e.g. asthma attacks are prevented proactively by improving disease control with the help of guided self-management. Networking of allergy experts with primary care doctors and nurses as well with pharmacists is the key for effective implementation. Non-governmental organizations have started a campaign to increase allergy awareness and knowledge among patients and general public. It is time to act, when allergic individuals are becoming a majority of Western populations and their numbers are in rapid increase worldwide. The first results of the Finnish Programme indicate that allergy burden can be reduced with relatively simple means.

Exacerbación de asma infantil en Unidad de Paciente Crítico: caracterización clínica / Asthma exacerbation in a Pediatric Intensive Care Unit: clinical features

Introducción: Algunos niños asmáticos presentan exacerbaciones que motivan su ingreso a Unidad de Paciente Crítico (UPC). A nivel nacional no existen publicaciones al respecto. El objetivo del estudio fue conocer las características clínicas de los niños con crisis asmáticas que requieren manejo en UPC en el Hospital Roberto del Río. Pacientes y Método: Estudio retrospectivo, descriptivo en mayores de 4 años, egresados de UPC con diagnóstico de crisis de asma en un período de tres años. Resultados: 67 niños requirieron manejo en UPC El promedio de edad fue 7 años y el de hospitalización 4 días. En 59 pacientes se utilizó Ventilación Mecánica No Invasiva (VMNI). Del total de pacientes sólo 27 tenía diagnóstico previo de asma, observándose buena adherencia al tratamiento sólo en 7. Conclusiones: Sólo el 40 por ciento de los pacientes asmáticos tenían el diagnóstico de asma antes de la hospitalización y la mayoría de ellos presentaba una pobre adherencia al tratamiento. En el manejo destaca un alto porcentaje de uso de VMNI.

Introduction: Some asthmatic children present severe exacerbations, demanding hospitalization in the Pediatric Intensive Care Unit (PICU). On a national Chilean scale, there is no published data about these patients. The objective of this study was to evaluate the clinical features of children with asthmatic exacerbations requiring PICU management at Roberto del Río Children's Hospital in Santiago de Chile. Patients and Method: Retrospective and descriptive study in children above 4 years of age discharged from PICU with diagnosis of asthmatic exacerbation during a three years period. Results: 67 children required treatment in PICU. The average of age was 7 years old, while the average of hospital stay was 4 days. Non invasive ventilation (NIV) was used in 59 patients. Only 27 patients had previous diagnosis of asthma, with good treatment adherence only in 7 of them. Conclusions: Before being hospitalized, only 40 percent of the asthmatic patients were diagnosed as asthmatic and most of them had a bad treatment compliance. NIVwas used in a remarkably high percentage of these patients.

A Case of Tramadol Induced Asthma Attack in a Patient with Samter's Triad / 대한이비인후과학회지

Samter's triad is a well known syndrome and is characterized by a triad of asthma, aspirin or NSAID sensitivity and chronic sinusitis with nasal polyp. Chronic sinusitis with Samter's triad is difficult to treat completely and has poor prognosis. Tramadol is a non-opioid analgesic that rarely shows respiratory suppression and is known to be relatively safe because it does not inhibit prostaglandin synthesis. For that reason, patients with asthma may avoid drug-induced exacerbations of the disease by substituting Tramadol for NSAIDs. We experienced a case of asthma attack in a patient with Samter's triad after Tramadol injection.

Cases Report of Bronchial Asthma Attack Successfully Treated with Kampo Medicine / 日本東洋医学雑誌

Bronchial asthma is manifested pathophysiologically by a narrowing of air passages with eosinophilic inflammation, and clinically by paroxysmal dyspnea. Usually, the treatment of asthma is governed by the Japanese guidelines for the prevention and control of bronchial asthma. We report two cases of bronchial asthma attack successfully treated with Kampo medicine. For their safety, the patients were hospitalized with informed consent, and evaluated carefully by means of various measures, such as pulse oximeter and peak expiratory flow rate.<br>In both cases, no application of additional occidental agents was made, except those used before current episode.<br>However, while modern Western medicine now sweeps over in the treatment of bronchial asthma attack, it is suggested that the Kampo medicine is comparable, in cases where the patients are hospitalized with informed consent, and evaluated carefully. Nevertheless it is proper that the therapy should be intensified in accordance with the guidelines in case of deterioration against the Kampo treatment.

An analysis on the treatment outcome of acute asthma attack / 천식및알레르기

BACKGROUND AND OBJECTIVE: There has been little clinical data on the treatment outcome of patients with acute asthma attack in Korea. We designed a management protocol of acute asthma, and analyzed clinical p arameters obtained from this protocol. METHOD: A total of 32 cases with acute asthma were treated with oxygen, beta2 agonist, and methylprednisolone. Ipratropium was added in cases of severe attack. After 90 minutes, intravenous aminophylline was given to the patients with poor response. RESULT: Beta2 agonist and methylprednisolone were sufficient for symptom control in 17 cases. Ipratropium and aminophylline were added in 6 and 9 cases, respectively. There was no difference in improvement of PEF, heart rate, respiratory rate, PaO2, PaCO2, and SaO2 at 90 minutes and 8 hours between beta2 agonist inhalation and subcutaneous group. Serum potassium concentration levels significantly decreased in patients treated with ipratropium of aminophylline(n=15, 4.17+/-0.45 vs. 3.99+/-0.35mM/L, p0.05). CONCLUSION: Subcutaneous beta2 agonist may be an alternative to inhalant beta2 agonist for the emergency treatment of acute asthma, and we think a consensus regarding use of aminophylline in the emergency room should be made.

A case-crossover study between air pollution and hospital emergency room visits by asthma attack / 대한산업의학회지

OBJECTIVES: This study, using case-crossover design, search a relationship between changing levels of air pollutants and asthma attack in asthma patients. METHODS: We searched the daily total number of asthmatic patients at hospital' s emergency room in Seoul, Korea by investigating total 49 general hospitals emergency room records. Otherwise, We investigated medical records of asthmatic patients at one of the 49 hospitals we have searched. We investigated addresses that they are living, diagnosis, smoking history, whether respiratory infection or not, medications. We analyzed the data by 1:m conditional logistic regression used when matched case-control study is analyzed. Control periods were chosen by bidirectional paired matching technique 7, 14 days before and after case periods. RESULTS: the relative risk of asthmatic attack by 100 ppm ozone increase between June and September were 1.348(95 % CI = 1.010~1.619). Between November and February, the relative risk by 100 /m TSP increase, 100ppb sulfur dioxide and nitrogen dioxide were respectively 1.278(1.010~1.619), 1.237(1.019~1.502), 1.285(1.006~1.640). In stratified analysis, the relative risk were significant when the asthmatic patients were children aged 15 years or below, when there were respiratory infection, and when the patients took medications irregularly CONCLUSIONS: There was statistically significant association between ambient levels of air pollutants and asthmatic attack. So, we have to exert our efforts to minimize the air pollution effectively, to protect public health from air pollution.
