Exposure to low levels of volatile organic compounds (VOCs) in ordinary life is suspected be related oxidative stress and decreased lung function. This study evaluated whether exposure ambient VOCs indoor air affects airway inflammation.Thirty-four subjects from the hospital that had moved a new building were enrolled. Symptoms sick syndrome, pulmonary function tests, fractional exhaled nitric oxide (FeNO) evaluated, random urine samples collected 1 week before after move. Urine analyzed for...
Recent evidence suggests that cough hypersensitivity may be a common feature of chronic in adults. However, the clinical relevance remains unclear. This study evaluated cough-related symptom profile and impact adults with cough.This cross-sectional multi-center compared laryngeal sensations triggers patients unexplained following investigations unselected newly referred for cough. A structured questionnaire was used to assess abnormal triggers. Patients were also using Leicester Cough...
ABSTRACT Background and objective: Reactivation of hepatitis B virus (HBV) is thought to be associated with immunosuppressive treatments, but insufficient information available on the effect corticosteroids. The aim this study was evaluate risk HBV reactivation in surface antigen‐seropositive patients asthma or COPD, who were treated systemic corticosteroids (SCS) addition inhaled (ICS). Methods: Patients COPD ( n = 198), had been ICS, identified retrospectively. To additional effects SCS,...

There are no specific tools for measurement of the severity chronic cough in Korea. We developed a Korean version Leicester Cough Questionnaire (LCQ) and tested its scaling clinical properties.The LCQ was adapted conditions following forward-backward translation procedure. All patients referred to clinics at 5 university hospitals between May 2011 October 2013 completed 2 questionnaires, Short-Form 36 (SF-36), upon presentation Global Rating Change (GRC) follow-up visits after or 4 weeks....
Despite the high burden and frequency of urticaria, its epidemiology is not well known. We investigated various type urticaria in Korea changes annual prevalence over 5 years.We used data from 2010 to 2014 Health Insurance Review Assessment database, which covers claims 97.0% South Korean population. Patients aged > 10 years old were included this study. The presence was identified on physician-certified diagnoses using International Classification Diseases 10th Revision (ICD-10) codes that...

The evaluated effects, including acute exacerbation rates, maintenance oral corticosteroid dosages,...
Abstract Background While the clinical characteristics and outcomes of asthma‐chronic obstructive pulmonary disease (COPD) overlap (ACO) have been frequently compared with those COPD or asthma, prevalence features ACO in patients severe asthma are unclear. Objectives Evaluation using Korean registry. Methods At time registration, was determined by attending specialists. Patients were classified into non‐ACO groups, demographic these two groups compared. Results Of 482 23.7% had ACO. group...
Rosacea is a chronic inflammatory skin disease. Recent studies have indicated its impacts on systemic health beyond dermatological symptoms. The gut-skin axis theory, which explores the interaction between gastrointestinal and health, may explain influence of rosacea disorders. This study investigates potential link risk developing irritable bowel syndrome (IBS) using Korean National Health Insurance Service-National Sample Cohort (NHIS-NSC). Data for this retrospective cohort were sourced...
Background The relationship between pre-treatment levels of blood eosinophil count (BEC), fractional exhaled nitric oxide (FeNO), and sputum eosinophils (Sp-EOS) treatment response to monoclonal antibodies (mAbs) in severe eosinophilic asthma (SEA) remain unclear. Objective We evaluated BEC, FeNO, Sp-EOS, their combinations as predictors responses patients with SEA undergoing anti-IL5/IL5Rα or anti-IL-4Rα antibody therapies. Methods study included 153 adult (59 94 anti-IL4Rα users). Logistic...

The present study explored real-world effectiveness and safety a Korean cohort, filling critical gap current research. This multi-center retrospective used data from Severe Asthma Registry, involving 67 patients treated with mepolizumab uncontrolled asthma between September 2017 July 2022. We assessed effects on acute exacerbations,...
The Leicester Cough Questionnaire (LCQ) is a validated tool for assessing cough-related impairments across three domains: physical, psychological, and social.

Adult patients with from 16 respiratory centers who completed LCQ diagnostic workup were retrospectively analyzed. Spearman's rank correlation analysis was conducted to evaluate correlations items domains. Causal mediation decomposed total...
<b><i>Background:</i></b> Obesity is a risk factor for asthma in the general population, but effect of obesity on airway hyperresponsiveness (AFHR) or inflammation not clear. This study evaluated relationship between and asthma, assessing aspects symptoms, AHR, severity. <b><i>Methods:</i></b> In total, 852 patients with diagnosed by specialists based AHR as confirmed methacholine bronchial provocation test, were enrolled from Cohort Reality...
Purpose: This retrospective study was conducted to estimate the effects of climate factors and air pollution on asthma exacerbations using a casecrossover analysis.Methods: Patients who visited emergency department (ED) 2 university hospitals in Chuncheon for from January 1, 2006, December 31, 2011, were enrolled.Daily average data meteorological (temperature, daily temperature range, relative humidity, wind speed, atmospheric pressure, presence rain, solar irradiation, fog) levels gaseous...
