ABSTRACT

A acupuntura se caracteriza pela estimulação de pontos cutâneos específicos por meio do uso de agulhas. A auriculoterapia consiste na estimulação mecânica de pontos específicos do pavilhão auricular com esferas de aço, ouro, prata, plástico, agulhas ou sementes de mostarda. A acupuntura é recomendada para promoção, manutenção e recuperação da saúde, bem como prevenção de agravos e doenças. Além disso, parece propiciar a liberação de neurotransmissores e outras substâncias responsáveis pela promoção da analgesia. A auriculoterapia promove a regulação psíquico orgânica do indivíduo. Ambas as prá ticas foram incorporadas no SUS mediante Portaria nº 971, de 03 de maio de 2006. Qual é a eficácia e a segurança da acupuntura e da auriculoterapia para o tratamento de asma em adultos e/ou idosos? As buscas foram realizadas em sete bases de dados sem restrição de ano de publicação. Os critérios de inclusão foram: revisões sistemáticas em inglês, português e espanhol que avaliaram os efeitos da acupuntura e auriculoterapia no tratamento de asma na população adulta e idosa. A avaliação da qualidade metodológica foi realizada por meio da ferramenta AMSTAR 2, feita por uma pesquisadora e revisada por outra. Nesta revisão rápida, produzida em cinco dias, foram utilizados atalhos metodológicos, de maneira que apenas o processo de seleção foi realizado em duplicidade e de forma independente. De 142 relatos recuperados nas bases de dados, foram incluídas cinco revisões sistemáticas que atenderam aos critérios de elegibilidade. A pergunta de pesquisa incluiu acupuntura e auriculoterapia, o que orientou as buscas de evidências. No entanto, não foram identificados estudos sobre auriculoterapia e a maioria das revisões analisou um tipo específico de acupuntura, denominada farmacopuntura, uma técnica que combina acupuntura com injeção de ervas medicinais. De maneira geral, a farmacopuntura combinada ou não a outros tratamentos, mostrou melhores resultados, em relação a seus comparadores, nos seguin tes desfechos: taxa de resposta e melhora dos sintomas de adultos com asma, melhora da Capacidade Vital Forçada (CVF), do Volume Expiratório Forçado em 1 segundo (VEF1), da relação VEF1/CVF e no Pico de Fluxo Expiratório (PFE). Os resultados sobre acupuntura foram melhores com relação a taxa de melhora dos sintomas de asma e do VEF1. Duas revisões avaliaram a segurança das intervenções, com relatos sobre ocorrência de eventos adversosleves com o uso da farmacopuntura. Esta revisão identificou alguns benefícios da acupuntura e farmacopuntura como tratamento adjuvante em pessoas com asma. No entanto, é necessário interpretar estes resultados com cautela, devido à diversidade de terapias utilizadas nos estudos primários e à qualidade metodológica das revisões sistemáticas, avaliadas como de confiança baixa ou criticamente baixa.

ABSTRACT

INTRODUCTION: Asthma is characterized by a narrowing and inflammation of the bronchi, with symptoms of dyspnea, fatigue and exercise limitation. Physical therapy includes inspiratory muscle training and breathing exercises, given that an increase in inspiratory muscle strength and resistance can improve the symptoms of the diseaseOBJECTIVE: To describe the effects of inspiratory muscle training (IMT) and breathing exercises in children with asthmaMETHODS: This is a systematic review of the literature using the Cochrane, PubMed Scopus e Web of Science databases. The following descriptors were used: asthma, inspiratory muscle training, breathing exercises and child in Portuguese, English and Spanish. Two independent evaluators screened studies that used breathing exercises and IMT in children with asthmaRESULTS: Of a total of 312 titles, eight studies were included, of which six are randomized clinical trials and two are observational studies All the studies included breathing exercises, with the objective of adjusting breathing patterns and pulmonary ventilation, reducing pulmonary hyperinflation, bronchospasm and sensation of dyspnea. However, as these exercises were not performed solely, the effects of this intervention could not be verified. Two studies performed IMT and showed an increase in maximal respiratory pressureCONCLUSION: Breathing exercises are widely used in clinical practice as part of the management of asthma in children; however it is not possible to measure the effects in this population. IMT seems to improve inspiratory and expiratory muscle strength, but its indication in the pediatric population is not a standard procedure


INTRODUÇÃO: Asma é caracterizada por estreitamento e inflamação dos brônquios, com sintomas de dispneia, fadiga e limitação aos exercícios. O tratamento fisioterapêutico engloba treinamento muscular inspiratório e exercícios respiratórios, pois o aumento da força e resistência da musculatura inspiratória podem melhorar os sintomas da doençaOBJETIVO: Descrever os efeitos do treinamento muscular inspiratório (TMI) e dos exercícios respiratórios na criança com asmaMÉTODO: Revisão sistemática da literatura conduzida nas bases de dados Cochrane, PubMed, Scopus e Web of Science. Utilizou-se os descritores: asma, treinamento muscular inspiratório, exercícios respiratórios e criança e seus correlatos em inglês e espanhol. Dois avaliadores independentes elencaram estudos que realizaram intervenção com exercícios respiratórios e TMI na criança com asmaRESULTADOS: De um total de 312 títulos, foram incluídos oito estudos, dos quais seis são ensaios clínicos randomizados e dois observacionais. Todos os trabalhos incluíram exercícios respiratórios, com o objetivo de adequar o padrão respiratório e a ventilação pulmonar, reduzir a hiperinsuflação pulmonar, o broncoespasmo e a sensação de dispneia, porém como não foram realizados de forma isolada, comprometeu a verificação dos efeitos dessa intervenção. Dois estudos realizaram TMI e evidenciaram aumento nas pressões respiratórias máximasCONCLUSÃO: Exercícios respiratórios são muito utilizados na prática clínica como parte do manejo da criança com asma, entretanto ainda não é possível mensurar seus efeitos nessa população. O TMI parece melhorar a força muscular inspiratória e expiratória, mas sua indicação na população pediátrica ainda não é rotineira

ABSTRACT

Abstract Asthma is an inflammatory disease of the lungs, and it causes oxidative stress. Lavandula dentata is an aromatic herb with anti-oxidative and anti-inflammatory activities. This study examined the activity of L. dentata extract on a guinea pig model of asthma. Adult males were divided into five groups: First group was control, second was asthma model induced by OVA, third was treated with L. dentata extract orally (300 mg/kg) for 21 days; the fourth was an asthma model with L. dentata extract (300 mg/kg) and fifth was treated with Tween 80 for 21 days. OVA treatment increased IgE, triglycerides, total cholesterol, glucose levels in serum, WBC count in blood and MDA in lungs. Also, OVA reduced SOD activity, GSH content in lungs, and GGT activity in serum (p<0.05). L. dentata extract treatment in asthma model reduced elevated IgE, triglycerides, total cholesterol, glucose levels in serum, and MDA in lungs (p<0.05), while it increased GSH content in lungs (p<0.05). These results suggest the possibility that L . dentata extract can exert suppressive effects on asthma, and may provide evidence that it is a useful agent for the treatment of allergic airway disease, it also limits oxidative stress induced by OVA. L. dentata extract appears to have hypolipidemic and hypoglycemic activities.


Resumo A asma é uma doença inflamatória dos pulmões e causa estresse oxidativo. Lavandula dentata é uma erva aromática com atividades anti-oxidantes e antiinflamatórias. Este estudo examinou a atividade do extrato de L. dentata em um modelo de asma de cobaia. Os machos adultos foram divididos em cinco grupos: o primeiro grupo foi controle, o segundo modelo foi o da asma induzido pela OVA, o terceiro foi tratado com extrato de L. dentata por via oral (300 mg / kg) por 21 dias; o quarto foi um modelo de asma com extrato de L. dentata (300 mg / kg) e o quinto foi tratado com Tween 80 por 21 dias. O tratamento com OVA aumentou a IgE, os triglicerídeos, o colesterol total, os níveis de glicose no soro, a contagem de leucócitos no sangue e o MDA nos pulmões. Além disso, o OVA reduziu a atividade da SOD, o conteúdo de GSH nos pulmões e a atividade da GGT no soro (p <0,05). O tratamento com extrato de L. dentata no modelo de asma reduziu a IgE elevada, triglicérides, colesterol total, níveis séricos de glicose e MDA nos pulmões (p <0,05), enquanto aumentou o conteúdo de GSH nos pulmões (p <0,05). Estes resultados sugerem a possibilidade do extrato de L. dentata poder exercer efeitos supressores sobre a asma, e pode fornecer evidências de que é um agente útil para o tratamento de doenças alérgicas das vias aéreas, além de limitar o estresse oxidativo induzido pela OVA. O extrato de L. dentata parece ter atividades hipolipemiantes e hipoglicêmicas.

ABSTRACT

Introducción. El asma es una enfermedad inflamatoria crónica con alta prevalencia en pacientes pediátricos. Existen resultados contradictorios respecto al efecto de esta enfermedad en los índices de caries dental. El objetivo del estudio fue determinar la prevalencia de caries dental en pacientes pediátricos asmáticos con medicación inhalatoria. Población y métodos. Estudio de casos y controles cuya muestra estuvo conformada por pacientes pediátricos que acudieron al Centro Médico Naval "Cirujano Mayor Santiago Távara" de diciembre de 2014 a marzo de 2015. Se dividieron en dos grupos: el primero (casos), integrado por pacientes asmáticos que utilizaban inhaladores en su tratamiento; el segundo (controles), por pacientes sanos del mismo nosocomio. Se realizó una evaluación médica para determinar tipo, tiempo y frecuencia del tratamiento y un examen oral para determinar la prevalencia de caries dental y el índice de dientes cariados, perdidos y obturados (CPOD). Resultados. Se encontró que la prevalencia de caries dental en el grupo control fue del 34,2 %, mientras, en el grupo casos, fue del 28,3 % (p = 0,094). Con respecto al índice de caries dental, el grupo control presentó CPOD de 4,73 ± 0,32, y el grupo casos, de 3,98 ± 0,31 (p = 0,08). Sin embargo, se evidenció que, a mayor tiempo de tratamiento con los inhaladores, el índice CPOD aumentaba significativamente (p = 0,04).Conclusiones. La medicación inhalatoria no incrementa la prevalencia de caries dental en pacientes pediátricos asmáticos. Sin embargo, existe una relación directa entre la duración del tratamiento y la prevalencia de caries dental


Introduction. Asthma is a chronic inflammatory disease that is highly prevalent among pediatric patients. The results about the effect of asthma on the rate of dental caries are contradictory. The objective of this study was to determine the prevalence of dental caries in asthma pediatric patients using inhaled drugs. Population and methods. Case-control study in a sample made up of pediatric patients who attended Centro Médico Naval "Cirujano Mayor Santiago Távara" between December 2014 and March 2015. Patients were divided into two groups: group A (cases) included asthma patients using inhalers as part of their treatment; group B (controls), healthy subjects who attended the same facility. A medical examination was done to determine the type, time, and frequency of treatment and an oral exam, to establish the prevalence of dental caries and the decayed, missing, and filled teeth (DMFT) index. Results. The prevalence of dental caries was 34.2 % in the control group and 28.3 % in the case group (p = 0.094). In relation to the rate of dental caries, the DMFT index in the control group was 4.73 ± 0.32, and 3.98 ± 0.31 in the case group (p = 0.08). However, it was evidenced that a longer duration of inhaler use led to a significantly higher DMFT index (p = 0.04).Conclusions. Inhaled drugs do not increase the prevalence of dental caries in asthma pediatric patients. However, there is a direct relationship between treatment duration and the prevalence of dental caries.

ABSTRACT

MicroRNAs (miRs) are single-stranded RNAs of 18-25 nucleotides. These molecules regulate gene expression at the post-transcriptional level; several of these are differentially expressed in asthma as well as in viral acute respiratory infections (ARIs), the main triggers of acute asthma exacerbations. In recent years, miRs have been studied in order to discover drug targets as well as biomarkers for diagnosis, disease severity and prognosis. We describe recent findings on miR expression and function in asthma and their role in the regulation of viral ARIs, according to cell tissue specificity and asthma severity. By combining the above information, we identify miRs that may be important in virus-induced asthma exacerbations. This is the first attempt to link miR profiles of asthmatic patients and ARI-induced miRs, addressing the question of whether there might be a specific miR deficit in asthmatic subjects that make them more susceptible and/or reactive to infection.

ABSTRACT

Improved understanding of the contribution of immune-inflammatory mechanisms in allergic diseases and asthma has encouraged development of biologicals and small molecules specifically targeting the innate and adaptive immune response. There are several critical points impacting the efficacy of this stratified approach, from the complexity of disease endotypes to the effectiveness in real-world settings. We discuss here how these barriers can be overcome to facilitate the development of implementation science for allergic diseases and asthma.

ABSTRACT

PURPOSE: The effect of air pollution-related particulate matter (PM) on epithelial barrier function and tight junction (TJ) expression in human nasal mucosa has not been studied to date. This study therefore aimed to assess the direct impact of PM with an aerodynamic diameter less than 2.5 μm (PM2.5) on the barrier function and TJ molecular expression of human nasal epithelial cells. METHODS: Air-liquid interface cultures were established with epithelial cells derived from noninflammatory nasal mucosal tissue collected from patients undergoing paranasal sinus surgery. Confluent cultures were exposed to 50 or 100 µg/mL PM2.5 for up to 72 hours, and assessed for 1) epithelial barrier integrity as measured by transepithelial resistance (TER) and permeability of fluorescein isothiocyanate (FITC) 4 kDa; 2) expression of TJs using real-time quantitative polymerase chain reaction and immunofluorescence staining, and 3) proinflammatory cytokines by luminometric bead array or enzyme-linked immunosorbent assay. RESULTS: Compared to control medium, 50 and/or 100 µg/mL PM2.5-treatment 1) significantly decreased TER and increased FITC permeability, which could not be restored by budesonide pretreatment; 2) significantly decreased the expression of claudin-1 messenger RNA, claudin-1, occludin and ZO-1 protein; and 3) significantly increased production of the cytokines interleukin-8, TIMP metallopeptidase inhibitor 1 and thymic stromal lymphopoietin. CONCLUSIONS: Exposure to PM2.5 may lead to loss of barrier function in human nasal epithelium through decreased expression of TJ proteins and increased release of proinflammatory cytokines. These results suggest an important mechanism of susceptibility to rhinitis and rhinosinusitis in highly PM2.5-polluted areas.

ABSTRACT

PURPOSE: Data are lacking on the association between the allergic rhinitis (AR) phenotype and sensitization to specific allergens or bronchial hyperresponsiveness (BHR) in children. We here investigated risk factors and comorbidities, including sensitization to specific allergens and BHR, for the AR phenotype by AR and its Impact on Asthma (ARIA) classification in a general population-based birth cohort study. METHODS: We enrolled 606 children aged 7 years from the Panel Study of Korean Children. The AR phenotype was assigned in accordance with the ARIA classification in children. Skin prick tests and Provocholine provocation test were performed. Risk factors and comorbidities for AR phenotypes were then analyzed. RESULTS: The prevalence of mild and moderate to severe AR in our study cohort was 37.2% and 8.8%, respectively. Recent use of analgesics or antipyretics and current cat ownership were associated with the risk of mild persistent AR. Sensitizations to Dermatophagoides Pteronyssinus (Der p), Japanese hop and cat were associated with moderate to severe persistent AR. Children with moderate to severe AR had a higher risk of current asthma and BHR compared to mild AR cases (adjusted odds ratio [aOR], 5.26; 95% confidence interval [CI], 1.77–15.62). Moderate to severe AR with allergic sensitization was associated with the highest risk of BHR (aOR, 11.77; 95% CI, 3.40–40.74). CONCLUSIONS: Moderate to severe-persistent AR is more closely related to respiratory comorbidities and sensitizations than mild AR. Stratifying the AR phenotype by ARIA classification may assist in disease management.

ABSTRACT

PURPOSE: Childhood asthma has a considerable social impact and economic burden, especially in severe asthma. This study aimed to identify the proportion of childhood asthma severity and to evaluate associated factors for greater asthma severity. METHODS: This study was performed on 667 children aged 5–15 years with asthma from the nationwide 19 hospitals in the Korean childhood Asthma Study (KAS). Asthma was classified as mild intermittent, mild persistent, and moderate/severe persistent groups according to the National Asthma Education and Prevention Program recommendations. Multinomial logistic regression models were used to identify the associated factors for greater asthma severity. RESULTS: Mild persistent asthma was most prevalent (39.0%), followed by mild intermittent (37.6%), moderate persistent (22.8%), and severe persistent asthma (0.6%). Onset later than 6 years of age (adjusted odds ratio [aOR], 1.69 for mild persistent asthma; aOR, 1.92 for moderate/severe persistent asthma) tended to increase asthma severity. Exposure to environmental tobacco smoke (aOR, 1.53 for mild persistent asthma; aOR, 1.85 for moderate/severe persistent asthma), and current dog ownership with sensitization to dog dander (aOR, 5.86 for mild persistent asthma; aOR, 6.90 for moderate/severe persistent asthma) showed increasing trends with greater asthma severity. Lower maternal education levels (aOR, 2.32) and no usage of an air purifier in exposure to high levels of outdoor air pollution (aOR, 1.76) were associated with moderate/severe persistent asthma. CONCLUSIONS: Modification of identified environmental factors associated with greater asthma severity might help better control childhood asthma, thereby reducing the disease burden due to childhood asthma.

ABSTRACT

PURPOSE: Allergen immunotherapy (AIT) induces immunological tolerance, and there is increasing evidence of the clinical efficacy of AIT in the treatment of allergic asthma. However, the optimal parameters for asthma control in clinical trials are still unclear. We investigated the efficacy of AIT with respect to changes in the inhaled corticosteroid (ICS) dose in patients with allergic asthma. METHODS: A total of 117 adults with allergic asthma who had used ICS for more than 1 year in a single tertiary hospital in Korea were included in this retrospective study. We compared the clinical parameters and outcomes between the AIT group (ICS with AIT, n = 48) and the non-AIT group (ICS without AIT, n = 69) by applying an inverse probability of treatment weighting method. The patients in the AIT group had received subcutaneous AIT monthly as a maintenance treatment for more than 1 year. The changes in the ICS dose from baseline were evaluated in the 2 groups for 3 years. RESULTS: The proportion of responders who discontinued or decreased in the ICS dose with achieving control status of asthma was significantly higher in the AIT group than in the non-AIT group throughout the study period (at 6 months, 52.1% vs. 24.6%; at 1 year, 70.8% vs. 34.7%; at 2 years, 89.5% vs. 35.6%; at 3 years, 96.3% vs. 51.2%). Treatment responses did not differ significantly by type of allergen (single- or multi-allergens or 3 different products) used throughout the study period. CONCLUSIONS: Irrespective of the type of allergen, long-term maintenance AIT helps to spare ICS dose and achieve better control in patients with allergic asthma in real-world clinical practice.

ABSTRACT

PURPOSE: Immunological mechanisms underlying asthma exacerbation have not been elucidated. The aim of this study was to assess the associations of various asthma exacerbation traits with selected serum microRNA (miRNA) expression and T-cell subpopulations. METHODS: Twenty-one asthmatics were studied during asthma exacerbation (exacerbation visit [EV] and the follow-up visit [FV] at 6 weeks). At both visits, spirometry was performed, fractional exhaled nitric oxide (FeNO) was measured, and nasopharyngeal and blood samples were collected. In nasopharyngeal samples, respiratory viruses were assayed by multiplex polymerase chain reaction (PCR), and bacterial cultures were performed. Serum miRNAs were assayed with real-time PCR. T-cell surface markers, eosinophil progenitors and intracellular cytokines were assessed by flow cytometry. RESULTS: Two-thirds of patients had moderate or severe exacerbation and the FV, overall improvement in asthma control was observed. The mean expression of serum miRNA-126a, miRNA-16 and miRNA-21 was significantly lower at the EV than at the FV. At EV, miRNA-29b correlated with FeNO (r = 0.44, P < 0.05), and 5 of 7 miRNA tested correlated with pulmonary function tests. The number of cluster of differentiation (CD)45+CD4+interleukin (IL)4+ cells was significantly higher at the EV than at the FV, and positive correlations of T-regulatory cells and eosinophil progenitors with asthma control was found. At the EV, serum miRNAs negatively correlated with the number of T cells expressing IL-4, IL-17, IL-22 and interferon gamma, while at the FV both positive and negative correlations with T-cell subsets were observed. No association of detected pathogen (viruses and bacteria) in nasopharyngeal fluid with clinical, functional and immunological parameters was found. CONCLUSIONS: Epigenetic dysregulation during asthma exacerbation could be related to respiratory function, airway inflammation and T-cell cytokine expression.

ABSTRACT

PURPOSE: Occupational asthma may be induced by high- or low-molecular weight allergens (HMWA or LMWA, respectively). The study was conducted to compare the pattern of bronchial response in 200 HMWA-induced asthmatics (n = 130) and LMWA-induced asthmatics (n = 70). METHODS: The study participants underwent a single-blind, placebo-controlled specific inhalation challenge (SIC) with workplace allergens, accompanied by evaluation of non-specific bronchial hyperresponsiveness (NSBHR) with methacholine before and after the SIC. RESULTS: A single early bronchial response more frequently occurred in HMWA-induced asthmatics than in LMWA-induced asthmatics (86.2% vs. 20%). An isolated late bronchial response or atypical patterns were more frequently observed in LMWA-induced asthmatics than in LMWA-induced asthmatics (45.7% vs. 3.8% or 34.3% vs. 10%, respectively). Baseline NSBHR before SIC was more often detected in LMWA-induced asthmatics than in HMWA-induced asthmatics (81.4% vs. 54.6%), and the median value of the provocation concentration of methacholine was relevantly lower in these patients before and after SIC. A significant 3-fold increase in NSBHR after SIC was observed more often in LMWA-induced asthmatics than in HMWA-induced asthmatics (82.8% vs. 66.1%). In addition, compared to LMWA-induced asthmatics, HMWA-induced asthmatics were older, were more frequently active smokers, showed lower level of NSBHR, and more frequently continued their work in harmful occupational exposure. CONCLUSIONS: The results of this study suggest that HMWA-induced asthmatics may have milder clinical courses and that there is a possibility of job continuation despite asthma exacerbation requiring medical surveillance.

ABSTRACT

E-cigarettes (ECs) and heated tobacco products (HTPs) have become popular in Korea; hence, it is important to determine whether ECs and HTPs are less hazardous than combustible cigarettes (CCs). In general, the levels of harmful and potentially harmful constituents (HPHCs) are lower in ECs and HTPs than in CCs, although the levels of some heavy metals and HPHCs are higher in ECs and HTPs than in CCs. ECs and HTPs showed possible adverse effects on respiratory and cardiovascular system function, which could result in chronic respiratory and cardiovascular system diseases in animals. An analysis of biomarkers showed that ECs had possible adverse health effects on the respiratory and cardiovascular systems, in addition the effects of HTP on respiratory and cardiovascular systems were not significantly different than those of CC. Epidemiological studies identified positive associations between EC use and asthma, chronic obstructive pulmonary disease, and myocardial infarction. Only one epidemiologic study reported a positive association between ever using HTPs and asthma, allergic rhinitis, and atopic dermatitis among adolescents. Modelling studies of ECs did not show consistent findings regarding the health effects compared with those of CCs. A modeling study of HTPs, performed by tobacco industry, has been criticized for many unfounded assumptions. Lower levels of HPHCs in ECs and HTPs, compared with those in CCs, cannot be directly translated into health benefits because the relationship between exposure and effects is non-linear for cardiovascular diseases and because the duration of exposure is more important than the level of exposure in determining lung cancer mortality. In summary, there is no definite health benefit in using ECs or HTPs instead of CCs, for the individual or the population; hence, tobacco control measures should be the same for ECs, HTPs, and CCs. ECs and HTPs have become popular in Korea; hence, it is important to determine whether ECs and HTPs are less hazardous than CCs.

ABSTRACT

For the past three decades, more than a thousand of genetic studies have been performed to find out the genetic variants responsible for the risk of asthma. Until now, all of the discovered single nucleotide polymorphisms have explained genetic effects less than initially expected. Thus, clarification of environmental factors has been brought up to overcome the ‘missing’ heritability. The most exciting solution is epigenesis because it intervenes at the junction between the genome and the environment. Epigenesis is an alteration of genetic expression without changes of DNA sequence caused by environmental factors such as nutrients, allergens, cigarette smoke, air pollutants, use of drugs and infectious agents during pre- and post-natal periods and even in adulthood. Three major forms of epigenesis are composed of DNA methylation, histone modifications, and specific microRNA. Recently, several studies have been published on epigenesis in asthma and allergy as a powerful tool for research of genetic heritability in asthma albeit epigenetic changes are at the starting point to obtain the data on specific phenotypes of asthma. In this presentation, we mainly review the potential role of DNA CpG methylation in the risk of asthma and its sub-phenotypes including nonsteroidal anti-inflammatory exacerbated respiratory diseases.

ABSTRACT

BACKGROUND: Chronic cough is defined as a cough lasting more than 8 weeks and socio-economic burden of chronic cough is enormous. The characteristics of chronic cough in Korea are not well understood. The Korean Academy of Tuberculosis and Respiratory Diseases (KATRD) published guidelines on cough management in 2014. The current study evaluated the clinical characteristics of chronic cough in Korea and the efficacy of the KATRD guidelines.METHODS: This was a multi-center, retrospective observational study conducted in Korea. The participants were over 18 years of age. They had coughs lasting more than 8 weeks. Subjects with current pulmonary diseases, smokers, ex-smokers with more than 10 pack-years or who quit within the past 1 year, pregnant women, and users of cough-inducing medications were excluded. Evaluation and management of cough followed the KATRD cough-management guidelines.RESULTS: Participants with chronic cough in Korea showed age in the late forties and cough duration of more than 1 year. Upper airway cough syndrome was the most common cause of cough, followed by cough-variant asthma (CVA). Gastro-esophageal reflux diseases and eosinophilic bronchitis were less frequently observed. Following the KATRD cough-management guidelines, 91.2% of the subjects improved after 4 weeks of treatment. Responders were younger, had a longer duration of cough, and an initial impression of CVA. In univariate and multivariate analyses, an initial impression of CVA was the only factor related to better treatment response.CONCLUSION: The causes of chronic cough in Korea differed from those reported in other countries. The current Korean guidelines proved efficient for treating Korean patients with chronic cough.

ABSTRACT

BACKGROUND: Fractional exhaled nitric oxide (FeNO) is regarded as a potential biomarker for identifying eosinophilic inflammation. We aimed to evaluate the clinical implication of FeNO and its influence on inhaled corticosteroids (ICS) prescription rate in Korean chronic obstructive pulmonary disease (COPD) patients.METHODS: FeNO level and its association with clinical features were analyzed. Changes in the prescription rate of ICS before and after FeNO measurement were identified.RESULTS: A total of 160 COPD patients were divided into increased (≥25 parts per billion [ppb], n=74) and normal (<25 ppb, n=86) FeNO groups according to the recommendations from the American Thoracic Society. Compared with the normal FeNO group, the adjusted odds ratio for having history of asthma without wheezing and with wheezing in the increased FeNO group were 2.96 (95% confidence interval [CI], 1.40–6.29) and 4.24 (95% CI, 1.37–13.08), respectively. Only 21 out of 74 patients (28.4%) with increased FeNO prescribed ICS-containing inhaler and 18 of 86 patients (20.9%) with normal FeNO were given ICS-containing inhaler. Previous exacerbation, asthma, and wheezing were the major factors to maintain ICS at normal FeNO level and not to initiate ICS at increased FeNO level.CONCLUSION: Increased FeNO was associated with the history of asthma irrespective of wheezing. However, FeNO seemed to play a subsidiary role in the use of ICS-containing inhalers in real-world clinics, which was determined with prior exacerbation and clinical features suggesting Th2 inflammation.

ABSTRACT

BACKGROUND: Data on the natural history and prognostic variables of chronic urticaria (CU) are rare and information about spontaneous remission of CU is limited.OBJECTIVE: This study evaluated the natural history of CU and identified predictors for remission.METHODS: Total 329 Korean patients with CU, who had follow-ups more than 6 months after diagnosis during a 7-year period in the department of dermatology in three university hospitals were enrolled. Clinical data and laboratory findings obtained by medical records and telephone interviews were analyzed, retrospectively.RESULTS: The proportion recovered in 1, 3, and 5 years after the onset of CU was 10.8%, 18.8%, and 32.9%, respectively. The mean duration of CU was 6.3 years. There were no significant differences in median recovery time depending on sex, age group, severity of CU, and type of CU. The presence of angioedema was significantly related to CU severity. There were no differences in prognosis with respect to the presence of dermographism or angioedema. Patients with atopic dermatitis (AD) had a significantly worse prognosis than patients without a history of AD; but not in patients with the history of allergic rhinitis or asthma. Patients with abnormal laboratory findings did not differ significantly in prognosis.CONCLUSION: CU remission rate significantly differ according to the presence of AD. This study provides information about the natural course of CU of Korean patients.

ABSTRACT

The clinical phenotypes of nonsteroidal anti-inflammatory drug (NSAID) hypersensitivity are heterogeneous with various presentations including time of symptom onset, organ involvements, and underlying pathophysiology. Having a correct diagnosis can be challenging. Understanding their respective mechanisms as well as developing a comprehensive classification and diagnostic algorithm are pivotal for appropriate management strategy. Treatment modalities are based on the subtypes and severity of hypersensitivity reactions. Insights into the phenotypes and endotypes of hypersensitivity reactions enable personalized management in patients with suboptimal control of disease. This review updated the recent evidence of pathophysiology, classification, diagnostic algorithm, and management of NSAID hypersensitivity reactions.
