Professor Deog Kyeom Kim's research lab focuses on respiratory diseases, particularly chronic obstructive pulmonary disease (COPD) and asthma, with an emphasis on identifying genetic and biomarker influences on disease progression. The lab investigates the interplay between genetic loci, protein expression, and environmental factors such as nicotine dependence in shaping lung phenotypes and disease susceptibility. Utilizing large-scale population studies and clinical data, including KNHANES and clinical trial registries, the lab aims to uncover novel genetic determinants and clinical predictors of chronic respiratory conditions. Their work bridges genetics, clinical phenotyping, and public health to improve early diagnosis and personalized management of lung diseases.

Distant genetic loci and biomarker-coding genes affect circulating levels of COPD-related pneumoproteins. A subset of these protein quantitative trait loci may influence their gene expression in the lung and/or COPD susceptibility. Clinical trial registered with www.clinicaltrials.gov (NCT 00292552).
Nicotine dependence was a negative predictor for emphysema on CT in COPD and control smokers. Increased inflammation in more highly addicted current smokers could influence the CT lung density distribution, which may influence genetic association studies of emphysema phenotypes.
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 met
Although chronic cough is very common, its prevalence and causes have been rarely reported in the large general population including smokers. This study aimed to identify the prevalence of possible causes of chronic cough and their clinical impact.From Korean National Health and Nutrition Examination Survey (KNHANES) data including 119,280 adults aged over 40 years, 302 individuals with chronic cough were recruited irrespective of smoking status. Data from questionnaire, laboratory tests includi
Spinal osteophytic changes are known to be affected by differences in age, sex, population, and mechanical stress. We examined Joseon skeletons (n=87) to obtain vertebral osteophytosis data on a pre-modern Korean population. The mean osteophytic value (MOV) of vertebrae increased in the cervical-thoracic-lumbar order. More severe osteophytosis was found in the vertebrae (C5, T9, T10, and L4) farthest from the line of gravity, while the general pattern of vertebral osteophytosis appeared similar
This study suggests that physicians should note the clinical symptoms and laboratory findings of severe infection and effectiveness of pleural drainage to predicate which patients with a CAP needing thoracostomy for CPE will have a prolonged hospital stay.
Altered expression of the genes for TNF-alpha, cathepsin W and TNFRSF7 may be risk factors for the extrapulmonary dissemination of tuberculosis in humans.
The prevalence and clinical implications of discordance between Xpert MTB/RIF assays and the AdvanSure TB/NTM real-time polymerase chain reaction (PCR) for bronchial washing specimens have not been studied in pulmonary TB (PTB) patients. The discordant proportion and its clinical impact were evaluated in 320 patients from the bronchoscopy registry whose bronchial washing specimens were tested simultaneously with Xpert MTB/RIF and the TB/NTM PCR assay for three years, and the accuracy of the assa

Certain SNPs located on chromosome 6 or the <i>HLA-DQB2</i> gene were the top-scoring SNPs for the association with susceptibility to early COPD in the Korean GENIE cohort.
Pulmonary function deteriorates with worsening histological severity of NAFLD, especially at the fibrosis stage. The common pathogenesis of reduced pulmonary function and NAFLD fibrosis progression should be further explored.
More than one-fifth of patients had an inconsistent blood eosinophil level after the 1-year follow-up, and the AE-COPD rate according to ICS differed based on variability in eosinophils. Regular follow-up of blood eosinophils is required for COPD patients.
Acute exacerbation(s) of chronic obstructive pulmonary disease (AECOPD) tend to be critical and debilitating events leading to poorer outcomes in relation to chronic obstructive pulmonary disease (COPD) treatment modalities, and contribute to a higher and earlier mortality rate in COPD patients. Besides pro-active preventative measures intended to obviate acquisition of AECOPD, early recovery from severe AECOPD is an important issue in determining the long-term prognosis of patients diagnosed wi
