Objective: The aims of this study were to analyze the deficiency-excess pattern identification (虛實辨證) and compare it to the sputum cytokines of asthma patients. Method: 50 asthma patients who met the inclusion and exclusion criteria were included in this study. They were divided into two groups: deficiency and excess syndrome groups. Sputum examinations were performed including $TNF-{\alpha}$, Interleukin (IL)-4, IL-5, IL-10, and IL-13. The Quality of Life Questionnaire for Adult Korean Asthmatics (QLQAKA), the Visual Analog Scale(VAS), and heart rate variability (HRV) were also measured. We also conducted laboratory tests, including the hematological indexes. Results: Based on the pattern identification, 50 asthma patients can be divided into two categories of groups: the deficiency syndrome group (N=24) and the excess syndrome group (N=26). In the analysis of sputum cytokines, although the $TNF-{\alpha}$, IL-4 and IL-13 were at a higher level in the deficient pattern group than in the excess pattern group, it was insignificantly different. There was a negative correlation in the analysis of QLQAKA and VAS. In the analysis of HRV, although the mean value of VLF, LF, and HF in the deficiency syndrome group was higher than in the excess syndrome group, it was insignificantly different. There was no significant difference in the hematological tests between the deficiency and the excess syndrome group. The mean value of the IgE in the blood tests was five times greater than the reference value. Conclusion: The cytokines of sputum including $TNF-{\alpha}$, IL-4, IL-5, IL-10, and IL-13 were indifferent statistically. Reinforcing the healthy and eliminating the pathogenic factors should be considered.

Purpose: This study aims to determine the efficacy and safety of house dust mite (HDM)-sublingual immunotherapy (SLIT) in elderly patients with AR. Methods: A total of 45 patients aged ${\geq}60years$ with HDM-induced AR who had ${\geq}3$ A/H ratio on skin prick test and/or ${\geq}0.35IU/L$ to both Dermatophagoides farinae and Dermatophagoides pteronyssinus by ImmunoCAP were enrolled in 4 university hospitals. To evaluate additional effects of HDM-SLIT, they were randomized to the SLIT-treated group (n = 30) or control group (n = 15). Rhinoconjunctivitis total symptom score (RTSS), rhinoscopy score, Korean rhinoconjunctivitis quality of life questionnaire, rhinitis control assessment test, asthma control test scores, and adverse reactions, were assessed at the first visit (V1) and after 1 year of treatment (V5); for immunological evaluation, serum levels of HDM-specific immunoglobulin A/IgE/IgG1/IgG4 antibodies and basophil response to HDMs were compared between V1 and V5 in both groups. Results: There were no significant differences in demographics, RTSS, skin reactivity to HDMs, or serum total/specific IgE levels to HDMs (P > 0.05, respectively) between the 2 groups. Nasal symptom score and RTSS decreased significantly at year 1 in the 2 groups (P < 0.05). There were no significant differences in percent decrease in nasal symptom score and RTSS at year 1 between the 2 groups (P > 0.05); however, rhinoscopic nasal symptom score decreased significantly in the SLIT-treated group (P < 0.05). Immunological studies showed that serum specific IgA levels (not specific IgE/IgG) and CD203c expression on basophils decreased significantly at V5 in the SLIT-treated group (P = 0.011 and P = 0.001, respectively), not in the control group. The control group required more medications compared to the treatment group, but there were no differences in adverse reactions. Conclusions: It is suggested that HDM-SLIT for 1 year could induce symptom improvement and may induce immunomodulation in elderly rhinitis patients.
Influenza causes acute respiratory infections and various complications. Children in the high-risk group have higher complication and hospitalization rates than high-risk elderly individuals. Influenza prevention in children is important, as they can be a source infection spread in their communities. Influenza vaccination is strongly recommended for high-risk children with chronic underlying circulatory and respiratory disease, immature infants, and children receiving long-term immunosuppressant treatment or aspirin. However, vaccination rates in these children are low because of concerns regarding the exacerbation of underlying diseases and vaccine efficacy. To address these concerns, many clinical studies on children with underlying respiratory diseases have been conducted since the 1970s. Most of these reported no differences in immunogenicity or adverse reactions between healthy children and those with underlying respiratory diseases and no adverse effects of the influenza vaccine on the disease course. Further to these studies, the inactivated split-virus influenza vaccine is recommended for children with underlying respiratory disease, in many countries. However, the live-attenuated influenza vaccine (LAIV) is not recommended for children younger than 5 years with asthma or recurrent wheezing. Influenza vaccination is contraindicated in patients with severe allergies to egg, chicken, or feathers, because egg-cultivated influenza vaccines may contain ovalbumin. There has been no recent report of serious adverse events after influenza vaccination in children with egg allergy. However, many experts recommend the trivalent influenza vaccine for patients with severe egg allergy, with close observation for 30 minutes after vaccination. LAIV is still not recommended for patients with asthma or egg allergy.
Objectives : Asthma is a chronic inflammatory disorder of the airways by many cells such as mast cells, Th2 lymphocytes and eosinophile. The present study was aimed to evaluate the effects of Salviae miltiorrhizae (SM) on T cell cytokine production, mast cells. and eosinophils, Methods : We screened 13 herbs to find compounds with potential to control Th cytokine production. using concanavalin A (con A)-activated splenocyte cultures. Con A-activated $IFN-\gamma$ and IL-4 levels in supernatants of splenocyte cultures. Bone marrow derived mast cells (BMMC) were incubated with SM and then the expressions of membrane proteins of BMMC were analyzed by fluorescence activated cell sorter (FACS). BALB/c mice sensitized to ovalbumin (OVA) were challenged with aerosolized OVA for 6 weeks. During the last weeks some mice were treated with SM. Then eosinophils in bronchoalveolar lavage fluid (BALf) were counted and pathologic changes of lung tissue were observed with hematoxylin-eosin stain. Results : SM increased $IFN-\gamma$ level on splenocyte culture significantly. but had no significant effects on expressions of ICAM-1, CD62L, integrin $a_4$. c-kit, IL-3 receptors. CD11a, or IgE receptors of BMMC. SM treatment significantly inhibited eosinophil infiltrates in BALf and peribronchial lung inflammation. Conculusions : The present data suggested that SM may have an effect on Th cytokine secretion and eosinophils associated with asthma responses. Therefore SM might be of therapeutic value in treating asthma.

Mesenchymal stem cells (MSCs) are attractive alternatives to conventional anti-asthmatic drugs for severe asthma. Mechanisms underlying the anti-asthmatic effects of MSCs have not yet been elucidated. This study evaluated the anti-asthmatic effects of intravenously administered MSCs, focusing on macrophages and monocytes. Seven-week-old transgenic (Tg) mice with lung-specific overexpression of IL-13 were used to simulate chronic asthma. MSCs were intravenously administered four days before sampling. We examined changes in immune cell subpopulations, gene expression, and histological phenotypes. IL-13 Tg mice exhibited diverse features of chronic asthma, including severe type 2 inflammation, airway fibrosis, and mucus metaplasia. Intravenous administration of MSCs attenuated these asthmatic features just four days after a single treatment. MSC treatment significantly reduced SiglecF-CD11c-CD11b+ monocyte-derived macrophages (MoMs) and inhibited the polarization of MoMs into M2 macrophages, especially M2a and M2c. Furthermore, MSCs downregulated the excessive accumulation of Ly6c- monocytes in the lungs. While an intravenous adoptive transfer of Ly6c- monocytes promoted the infiltration of MoM and Th2 inflammation, that of MSC-exposed Ly6c- monocytes did not. Ex vivo Ly6c- MoMs upregulated M2-related genes, which were reduced by MSC treatment. Molecules secreted by Ly6c- MoMs from IL-13 Tg mice lungs upregulated the expression of fibrosis-related genes in fibroblasts, which were also suppressed by MSC treatment. In conclusion, intravenously administered MSCs attenuate asthma phenotypes of chronic asthma by modulating macrophages. Identifying M2 macrophage subtypes revealed that exposure to MSCs transforms the phenotype and function of macrophages. We suggest that Ly6c- monocytes could be a therapeutic target for asthma management.
CR asthma is associated with disease chronicity, a positive family history of asthma and in vitro and in vivo defects in mononuclear cell function. The HPA axis in CR asthmatics is suppressed normally by dexamethasone and the pharmacokinetic profile of an oral dose of prednisolone is similar to that found in CS subjects. In addition, competitive binding studies have shown that the ligand binding and nuclear translocation functions of the GR are similar in the two groups. Studies using gel retardation assay have indicated a defect in DNA binding in CR subjects. Chemical mutational analysis of the GR has shown that is not due to a defect in its structure at the cDNA level. Scatchard analysis of the GR/DNA and GR/ligand interactions suggests that there may be transcriptional interference of the GR with other transcriptionally active molecules leading to defective gene transcription.
The introduction of inhaled corticosteroids (ICS) for the management of asthma has led to a decrease in acute exacerbation of asthma. However, there are concerns regarding the safety of long-term ICS use, particularly pneumonia. Growing evidence indicates that ICS use is associated with an increased risk of pneumonia in patients with chronic obstructive pulmonary disease, whereas the risk in patients with asthma remains unclear. This review discusses the effect of ICS on pneumonia among patients with asthma to update the existing literature. Asthma is associated with an increased risk of pneumonia. Several hypotheses have been proposed to explain this association, including that asthma impairs the clearance of bacteria owing to chronic inflammation. Therefore, controlling airway inflammation with ICS may prevent the occurrence of pneumonia in asthma. In addition, two meta-analyses investigating randomized control trials showed that ICS use was associated with a protective effect against pneumonia in asthma.
Background: Inhaled corticosteroids (ICSs) are the most essential medication for asthma control. Many reports suggest that the usage of ICSs improves not only the control of asthma symptoms but also prevents exacerbation. We investigated whether increases in ICS prescriptions are associated with decreases in asthma exacerbation in the clinical practice setting. Methods: We retrospectively analyzed the database of adult asthma patients who had visited a tertiary referral hospital, the Asan Medical Center between January 2000 and December 2009. The number of emergency department (ED) visits, admissions, intensive care unit (ICU) care, deaths, and ICS prescriptions were analyzed to evaluate the time trend of asthma exacerbation as a function of the ICS prescription rate during the ten years. Results: The numbers of ED visits, admissions, and episodes of ICU care decreased during the ten years (p<0.001, p=0.033, p=0.001, respectively) while the number of ICS prescriptions increased (p<0.001). We found a correlation between the number of ICS prescriptions and the number of ED visits, admissions, or ICU care. For these outcomes, the correlation coefficients were r=-0.952, p<0.001; r=-0.673, p=0.033; r=-0.948, p<0.001, respectively. Conclusion: The number of ICS prescriptions increased during the past ten years while the number of asthma exacerbations decreased. Our results also showed a negative correlation between the ICS prescription rate and asthma exacerbation in the clinical practice setting. In other words, an increase in ICS prescription may be a major cause of a decrease in asthma exacerbations.

Asthma is a prevalent and serious health problem in Korea. Recently, the Korean Asthma Guideline has been updated by The Korean Academy of Tuberculosis and Respiratory Diseases (KATRD) in an effort to improve the clinical management of asthma. This guideline focuses on adult patients with asthma and aims to deliver up to date scientific evidence and recommendations to general physicians for the management of asthma. For this purpose, this guideline was updated following systematic review and meta-analysis of recent studies and adapting some points of international guidelines (Global Initiative for Asthma [GINA] report 2014, National Asthma Education and Prevention Program [NAEPP] 2007, British Thoracic Society [BTS/SIGN] asthma guideline 2012, and Canadian asthma guideline 2012). Updated issues include recommendations derived using the population, intervention, comparison, and outcomes (PICO) model, which produced 20 clinical questions on the management of asthma. It also covers a new definition of asthma, the importance of confirming various airflow limitations with spirometry, the epidemiology and the diagnostic flow of asthma in Korea, the importance and evidence for inhaled corticosteroids (ICS) and ICS/formoterol as a single maintenance and acute therapy in the stepwise management of asthma, assessment of severity of asthma and management of exacerbation, and an action plan to cope with exacerbation. This guideline includes clinical assessments, and treatment of asthma-chronic obstructive pulmonary disease overlap syndrome, management of asthma in specific conditions including severe asthma, elderly asthma, cough variant asthma, exercise-induced bronchial contraction, etc. The revised Korean Asthma Guideline is expected to be a useful resource in the management of asthma.
Objective: This study was designed to analyze the treatment effects of Chungsangboha-tang through retrospective chart reviews.Methods: Fifty-one outpatients who had visited the Allergy, Immune & Respiratory System Division at the Kyung Hee Korean Medicine Hospital and who had taken Chungsangboha-tang from February 1, 2006, to February 1, 2016, had their basic medical records and examinationsretrospectively reviewed with respect to IgE, eosinophil, AST, and ALT. The PFT results of 11 patients were also investigated with respect to FEV1, FVC, and FEV1/FVC.Results: The percentage of males and females was 49.02% and 50.98%, respectively. The past histories of patients included asthma (66.67%), unspecified cough (21.57%), COPD (9.80%), allergic rhinitis (7.84%), and others. The subjective symptoms included cough (82.35%), sputum (39.22%), dyspnea (37.25%), and others. The most numerous pattern identification was wheezing dyspnea. IgE was significantly reduced, and eosinophil had a reduced tendency after 116.76±160.40 days of taking Chungsangboha-tang. PFT results also significantly increased after 213.09±266.62 days, while AST and ALT results showed a reduced tendency. In the asthmatic group, IgE also showed a reduced tendency. In particular, IgE was significantly reduced in patient groups taking medicine for more than 12 weeks.Conclusions: The conditions of patients with chronic pulmonary disease such as asthma and COPD significantly improved with Chungsangboha-tang after more than 12 weeks.
