ABSTRACT

Background@#Only a few studies directly compared the therapeutic efficacy and safety of two pressurized metered-dose inhalers (pMDIs) in asthma. We analyzed the asthma treatment outcomes, safety, and patient preferences using formoterol/beclomethasone (FORM/BDP), a pMDI with extra-fine particles, compared with formoterol/budesonide (FORM/BUD), another pMDI with non-extra-fine particles. @*Methods@#In this randomized, double-blind, double-dummy parallel group study, 40 adult asthmatics were randomized to FORM/BDP group (n=18; active FORM/BDP and placebo FORM/BUD) or FORM/BUD group (n=22; active FORM/BUD and placebo FORM/BDP). During the two visits (baseline and end of 8-week treatment), subjects were asked to answer questionnaires including asthma control test (ACT), asthma control questionnaires (ACQ), and Quality of Life Questionnaire for Adult Korean Asthmatics (QLQAKA). Lung function, compliance with inhaler, and inhaler-handling skills were also assessed. @*Results@#Ten subjects in the FORM/BDP group and 14 in the FORM/BUD group completed follow-up visits. ACT, ACQ, QLQAKA (a primary outcome), and adverse events did not differ between two groups. We found that the increase in forced expiratory volume in 1 second/forced vital capacity and forced expiratory flow at 25% to 75% of the pulmonary volume in the FORM/BDP group was higher than in the FORM/BUD group. Regarding preference, subjects responded that the flume velocity of FORM/BDP was higher, but more adequate than that of FORM/BUD. They also answered that FORM/BDP reached the trachea and bronchus and irritated them significantly more than FORM/BUD. @*Conclusion@#The use of pMDI with extra-fine particles may relieve small airway obstruction more than the one with non-extra-fine particles despite no significant differences in overall treatment outcomes. Some asthmatics have a misconception about the adequacy of high flume velocity of pMDIs.

ABSTRACT

Hereditary angioedema (HAE) is a rare disease, but it severely interrupts daily life activities and can sometimes be life-threatening. Therefore, early diagnosis and prompt treatment of HAE attacks are critical. Physicians should be aware of how to diagnose and manage HAE to prepare not to miss a diagnosis when treating HAE patients. Physicians must also carry out tests to confirm the diagnosis of HAEs caused by C1 inhibitor deficiency (type 1) or C1 inhibitor dysfunction (type 2) in patients with recurrent angioedema. In addition, recent studies revealed another type of HAE which is not related to C1 inhibitor (normal C1 inhibitor HAE). Once HAE is confirmed, patients and their caregivers should be given with short-term and long-term treatment plans to relieve or prevent HAE attacks. HAE requires life-long measures, including psychological support for patients and self-management education.

ABSTRACT

Background/Aims@#Skin (STs) and drug provocation (DPTs) tests are essential for identifying the culprit drugs causing drug hypersensitivity reactions (DHRs). Several protocols have been developed for the identification of some culprit drugs, but they are neither thoroughly validated nor standardized. Furthermore, language barriers may impede the exchange of information necessary for test standardization. @*Methods@#We searched the Korean literature for articles on drug hypersensitivity published from 1933 to 2016 using the KoreaMed search engine and archives of Korean journals. We reviewed and rated all articles according to the description of STs and DPTs. @*Results@#Of the 632 articles obtained in our initial search, 34 had adequate descriptions of 15 STs and 22 DPTs. Up to 27 healthy control subjects in STs were enrolled to determine non-irritating concentrations. The concentrations used for intradermal tests were commonly a 1/10 dilution of those used for skin prick tests. The interpretations of the STs were mostly similar among researchers. For DPTs, most procedures were single-arm open-label tests of various drugs. The initial dose ranged from a quarter dose to a single therapeutic dose, depending on the severity of the original hypersensitivity reaction. The interval between doses was usually 30 to 60 minutes, and a positive reaction usually occurred within twice the time of the original reaction. @*Conclusions@#Efforts to distribute information are necessary to standardize protocols and better understand DHRs.

ABSTRACT

Background@#Fractional exhaled nitric oxide (FeNO) is a non-invasive marker for eosinophilic airway inflammation and a good predictor of response to corticosteroids. There is a need for a reliable and accurate measurement method, as FeNO measurements have been widely used in clinical practice. Our study aimed to compare two FeNO analyzers and derive a conversion equation for FeNO measurements in adults. @*Methods@#We included 99 participants who had chief complaints of chronic cough and difficulty in breathing. The participants underwent concurrent FeNO measurement using NIOX VERO (Circassia AB) and NObreath (Bedfont). We compared the values of the two devices and analyzed their correlation and agreement. We then formulated an equation to convert FeNO values measured by NObreath into those obtained by NIOX VERO. @*Results@#The mean age of the participants was 51.2±17.1 years, with a female predominance (58.6%). Approximately 60% of the participants had asthma. The FeNO level measured by NIOX VERO (median, 27; interquartile range [IQR], 15–45) was significantly lower than that measured by NObreath (median, 38; IQR, 22–58; p<0.001). There was a strong positive correlation between the two devices (r=0.779, p<0.001). Additionally, Bland-Altman plots and intraclass correlation coefficient demonstrated a good agreement. Using linear regression, we derived the following conversion equation: natural log (Ln) (NObreath)=0.728×Ln (NIOX VERO)+1.244. @*Conclusion@#The FeNO values of NIOX VERO and NObreath were in good agreement and had positive correlations. Our proposed conversion equation could help assess the accuracy of the two analyzers.

ABSTRACT

Allergen-specific immunotherapy (AIT) can alter the natural course of an allergic disease. It is widely held that the efficacy of a given therapeutic modality should be proven by well-designed double-blind placebo-controlled randomized clinical trials and meta-analyses. In this article, the therapeutic efficacy of AIT for allergic respiratory diseases, such as allergic rhinitis and asthma, is reviewed. In addition, potential clinical and experimental predictors of the treatment response are reviewed for AITs requiring long-term treatment, and for some allergic rhinitis and asthma patients who show no response to AIT.

ABSTRACT

Drug reaction with eosinophilia and systemic symptoms (DRESS) syndrome is a severe cutaneous adverse reaction involving various internal organs. Flare-ups after recovery from the initial presentation of DRESS are caused by relapse of drug-induced T-cell-mediated reactions. However, the specific underlying mechanism is unclear. Here, we report a case of a 60-year-old man with allopurinol-induced DRESS who suffered recurrent episodes of generalized rash with eosinophilia, which mimicked immune reconstitution inflammatory syndrome. Analysis of immunological profiles revealed that the percentages of T lymphocytes and regulatory T cells in the patient with DRESS were higher than those in healthy controls. In addition, there was a notable change in the subtype of monocytes in the patient with DRESS; the percentage of nonclassical monocytes increased, whereas that of classical monocytes decreased. Upon viral infection, nonclassical monocytes exhibited strong pro-inflammatory properties that skewed the immune response toward a Th2 profile, which was associated with persistent flare-ups of DRESS. Taken together, the results increase our understanding of the pathogenesis of DRESS as they suggest that expansion of nonclassical monocytes and Th2 cells drives disease pathogenesis.

ABSTRACT

Although allergen-specific immunotherapy (AIT) is a standard treatment for allergic diseases, only 5% or less of patients in whom AIT is indicated have been receiving immunotherapy because AIT needs a long-term therapeutic duration of up to 5 years. To overcome this limitation of conventional AIT, Kündig and his colleagues first introduced intralymphatic immunotherapy (ILIT) in patients with allergic rhinitis, publishing their results in 2008. Since then, 10 clinical trials that evaluated therapeutic efficacies and adverse effects of ILIT have been conducted. This article reviews the clinical trials of ILIT and suggests unmet needs in research fields of ILIT.

ABSTRACT

PURPOSE: Recent evidence suggests that cough hypersensitivity may be a common feature of chronic cough in adults. However, the clinical relevance remains unclear. This study evaluated the cough-related symptom profile and the clinical relevance and impact of cough hypersensitivity in adults with chronic cough. METHODS: This cross-sectional multi-center study compared cough-related laryngeal sensations and cough triggers in patients with unexplained chronic cough following investigations and in unselected patients newly referred for chronic cough. A structured questionnaire was used to assess abnormal laryngeal sensations and cough triggers. Patients with unexplained cough were also evaluated using the Leicester Cough Questionnaire (LCQ) and a cough visual analogue scale (VAS), and these scores were assessed for correlations with the number of triggers and laryngeal sensations. RESULTS: This study recruited 478 patients, including 62 with unexplained chronic cough and 416 with chronic cough. Most participants reported abnormal laryngeal sensations and cough triggers. Laryngeal sensations (4.4 ± 1.5 vs. 3.9 ± 1.9; P = 0.049) and cough triggers (6.9 ± 2.6 vs. 5.0 ± 2.8; P < 0.001) were more frequent in patients with unexplained chronic cough than in those with chronic cough. The number of triggers and laryngeal sensations score significantly correlated with LCQ (r = −0.51, P < 0.001) and cough VAS score (r = 0.53, P < 0.001) in patients with unexplained chronic cough. CONCLUSIONS: Cough hypersensitivity may be a common feature in adult patients with chronic cough, especially those with unexplained chronic cough. Cough-related health status and cough severity were inversely associated with the number of triggers and laryngeal sensations, suggesting potential relevance of assessing cough hypersensitivity in chronic cough patients.

ABSTRACT

PURPOSE: Identifying microbial communities with 16S ribosomal RNA (rRNA) gene sequencing is a popular approach in microbiome studies, and various software tools and data resources have been developed for microbial analysis. Our aim in this study is investigating various available software tools and reference sequence databases to compare their performance in differentiating subject samples and negative controls. METHODS: We collected 4 negative control samples using various acquisition protocols, and 2 respiratory samples were acquired from a healthy subject also with different acquisition protocols. Quantitative methods were used to compare the results of taxonomy compositions of these 6 samples by varying the configuration of analysis software tools and reference databases. RESULTS: The results of taxonomy assignments showed relatively little difference, regardless of pipeline configurations and reference databases. Nevertheless, the effect on the discrepancy was larger using different software configurations than using different reference databases. In recognizing different samples, the 4 negative controls were clearly separable from the 2 subject samples. Additionally, there is a tendency to differentiate samples from different acquisition protocols. CONCLUSION: Our results suggest little difference in microbial compositions between different software tools and reference databases, but certain configurations can improve the separability of samples. Changing software tools shows a greater impact on results than changing reference databases; thus, it is necessary to utilize appropriate configurations based on the objectives of studies.

ABSTRACT

The prevalence of allergic diseases has increased dramatically in recent decades, and are now considered major chronic diseases at the global level. The increasing burden of allergic diseases has led to numerous worldwide and local researchers to investigate the time trends in its prevalence and identify its driving factors. Environmental changes such as urbanization and industrialization have been suggested to explain the increasing prevalence, but recent reports from Western countries suggest that this prevalence has reached a plateau or even possibly, started to decrease. However, such environmental changes are still occurring in many Asia-Pacific countries, including Korea, and it is speculated that the peak in allergy epidemics has yet to come. The present systematic literature review aimed to explore the time trends in the prevalence of allergic diseases in Korea and to identify the unmet needs for facilitating further studies.

ABSTRACT

PURPOSE: Since drug reaction with eosinophilia and systemic symptom (DRESS) syndrome is very rare and difficult to diagnose, its exact epidemiology is still unknown. If screening tools based on laboratory results or electronic medical records are available, the occurrence of DRESS syndrome can be monitored in real time. METHODS: To screen cases with DRESS syndrome, all the results of both eosinophil and alanine transaminase (ALT) level from July 2014 to June 2015 were analyzed by 36 searching conditions for the signal detection of 7 definite DRESS cases among 199,924 patients during the study period. Those searching conditions were diverse combinations of different cutoff levels of eosinophil and ALT with or without nursing records presenting skin symptoms. Sensitivity, specificity, positive predictive value (PPV) and negative predictive value were calculated for individual searching conditions. RESULTS: As cutoff levels of eosinophil and ALT for screening DRESS increased from 3% to 5% and 40 U/L to 300 U/L, respectively, the sensitivity decreased from 100% to 42.9% and the PPV increased from 0.06% to 13.0%. A combination of eosinophil >10% and ALT >300 U/L which had the highest PPV among 36 search conditions could detect DRESS syndrome by sensitivity 42.9% and PPV 13.0%. When nursing records for skin symptoms were added, PPV was augmented to 21.4%. CONCLUSION: A combination of eosinophil and ALT levels is a useful search condition for the screening of DRESS syndrome. Nursing records can provide an additional increment in PPV.

ABSTRACT

BACKGROUND/AIMS: Effective educational tools are important for increasing adherence to asthma guidelines and clinical improvement of asthma patients. We developed a computer-based interactive education program for asthma guideline named the Virtual Learning Center for Asthma Management (VLCAM). We evaluated the usefulness of program in terms of its effects on user awareness of asthma guideline and level of satisfaction. METHODS: Physicians-in-training at tertiary hospitals in Korea were enrolled in a cross-sectional questionnaire survey. The e-learning program on asthma guideline was conducted over a 2-week period. We investigated changes in the awareness of asthma guideline using 35-item self-administered questionnaire aiming at assessing physicians' knowledge, attitude, and practice. Satisfaction with the program was scored on 4-point Likert scales. RESULTS: A total of 158 physicians-in-training at six tertiary hospitals completed the survey. Compared with baseline, the overall awareness obtained from the scores of knowledge, attitude, and practice was improved significantly. Participants were satisfied with the VLCAM program in the following aspects: helpfulness, convenience, motivation, effectiveness, physicians' confidence, improvement of asthma management, and willingness to recommend. All items in user satisfaction questionnaires received high scores over 3 points. Moreover, the problem-based learning with a virtual patient received the highest user satisfaction among all parts of the program. CONCLUSIONS: Our computer-based e-learning program is useful for improving awareness of asthma management. It could improve adherence to asthma guidelines and enhance the quality of asthma care.

ABSTRACT

Drug reaction with eosinophilia and systemic symptoms (DRESS) syndrome is a rare but potentially fatal drug-induced systemic hypersensitivity response characterized by erythematous eruption, fever, leukocytosis with eosinophilia, and internal organ involvement. Antitubercular agents are potential causative agents for DRESS syndrome but difficult to verify as a culprit drug, since antitubercular agents are coadministered as a combination regimen. A 42-year-old female with endobronchial tuberculosis was diagnosed with DRESS syndrome after 4-week treatment of isoniazid, rifampicin, ethambutol, and pyrazinamide with prednisolone 50 mg. All the antitubercular agents were stopped and replaced with levofloxacin, cycloserine, p-aminosalicylic acid, and kanamycin. However, severe exacerbation of DRESS syndrome compelled the patient to discontinue the administration of the second-line antitubercular agents. Two months later, the patient underwent a patch test for all the antitubercular agents which had been used, and the results showed positivity to isoniazid and cycloserine. We report a rare case of DRESS syndrome that reacted to cycloserine as well as isoniazid. Development of coreactivity to other drugs should be differentiated with a flare-up reaction in the management of DRESS syndrome.

ABSTRACT

Hyper-IgE syndrome (HIES) is a very rare primary immune deficiency characterized by elevated serum IgE levels, recurrent bacterial infections, chronic dermatitis, and connective tissue abnormalities. Autosomal dominant (AD) HIES involves a mutation in signal transducer and activator of transcription 3 (STAT3) that leads to an impaired T(H)17 response. STAT3 signaling is also involved in the function of RORγt⁺ type 3 innate lymphoid cells (ILC3s) and RORγt⁺T(H)17 cells. The aim of this study was to investigate the role of innate immune cells such as innate lymphoid cells (ILCs), granulocytes, and monocytes in a patient with HIES. Peripheral blood mononuclear cells (PBMCs) from a patient with HIES and three age-matched healthy controls were obtained for the analysis of the innate and adaptive immune cells. The frequencies of ILCs in PBMCs were lower in the patient with HIES than in the controls. Moreover, granulocyte-macrophage colony-stimulating factor (GM-CSF) and IL-17A produced by ILC3s in PBMCs were lower in the patient with HIES than the controls. Compared with the controls, classical monocytes (CD14⁺CD16(low)), which have a high antimicrobial capability, were also lower in the patient with HIES, while non-classical monocytes (CD14(low)CD16⁺) as well as intermediate monocytes (CD14⁺CD16(intermediate)) were higher. Taken together, these results indicate that the impaired immune defense against pathogenic microbes in the patient with HIES might be partially explained by functional defects in ILC3s and inflammatory monocytes.

ABSTRACT

Eperisone is a widely used muscle relaxant and believed to be relatively free of adverse drug reactions. However, a rare case of fatal anaphylaxis has been reported in the literature. Poor awareness due to its rarity and combined administration with other drugs are the major hurdles in diagnosing eperisone-induced anaphylaxis. We experienced 3 cases of immediate hypersensitivity reaction occurring after eperisone administration. Case 1, a 63-year-old female, was admitted via the Emergency Department with urticaria, generalized erythroderma, sore throat, chest discomfort, and dyspnea within 1 hour after administration of common cold remedy. Case 2, a 58-year-old male, visited our allergy clinic to detect culprit drugs. He experienced itching, urticaria, hypotension for several hours after administration of the pills for back pain in the last 3 years. Case 3, a 58-year-old male developed urticaria and dyspnea after administration of medication for a headache. He also experienced urticaria and facial edema after administration of the common cold remedy. Among the medications, eperisone hydrochloride was proven as the culprit drug and others were excluded through oral provocation tests. We advised them to avoid eperisone and issued drug safety card. Clinicians should be aware that eperisone hydrochloride is a potential culprit agent of fatal anaphylaxis.

ABSTRACT

Antiplatelet agents, such as aspirin, clopidogrel, and cilostazol, are essential for the treatment and prevention of cardiovascular, cerebrovascular, and peripheral vascular diseases. A 53-year-old male with aspirin hypersensitivity developed dizziness, which was caused by severe stenosis of the left vertebral artery. Clopidogrel was administerted, but discontinued due to generalized urticaria and angioedema. As an alternative drug, cilostazol was administered, but discontinued again because of the same adverse reactions. Desensitization was planned as other alternative antiplatelet agents were not available. Initially, aspirin desensitization was successfully performed. One day after aspirin desensitization, clopidogrel desensitization was sequentially done successfully. After a few months, cilostazole desensitization was performed. During the follow-up period, he had to stop aspirin and cilostazol twice to prevent the risk of bleeding after a procedure and an operation. After discontinuing medicines, sequential desensitization of aspirin and cilostazol was successfully performed. Physicians should be aware that drug hypersensitivity could be induced by various kinds of antiplatelet agents and that desensitization could be the treatment of choice unless alternative medicines are available.

ABSTRACT

PURPOSE: Food-dependent exercise-induced anaphylaxis (FDEIA) is a rare subtype of food allergy in which both sensitization to food allergen and exercise as a trigger contribute to its development. However, its pathogenesis is still under investigation. This study compared clinical features, the causative foods, and the degree of sensitization to food between FDEIA and food anaphylaxis to characterize FDEIA more clearly. METHODS: We retrospectively reviewed the medical records of patients who were diagnosed with FDEIA (n=89) or food anaphylaxis (n=115) between 2003 and 2015 at Seoul National University Hospital. RESULTS: Subjects with FDEIA more frequently had urticaria than those with food anaphylaxis (88.8% vs. 76.5%, P=0.024). Whereas patients with FDEIA had less laryngeal edema than those with food anaphylaxis (12.4% vs. 30.4%, P=0.02). Wheat (67.4%) was the most common causative food allergen in FDEIA, whereas seafood (40.9%) was the most common culprit food allergen in food anaphylaxis. Also, subjects with FDEIA showed a lower atopic index score than those with food anaphylaxis (0.55±1.07 vs. 1.21±1.82, P=0.006). CONCLUSION: There were significant differences in clinical manifestation, causative food allergens and the degree of sensitization to food between FDEIA and food anaphylaxis.
