Measurement of Fractional Exhaled Nitric Oxide in Adults: Comparison of Two Different Analyzers (NIOX VERO and NObreath)
Sung-Yoon Kang, Sang Min Lee, Sang Pyo Lee
Tuberc Respir Dis. 2021;84(3):182-187.   Published online March 10, 2021
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...

Correlation between Telomere Length and Chronic Obstructive Pulmonary Disease–Related Phenotypes: Results from the Chronic Obstructive Pulmonary Disease in Dusty Areas (CODA) Cohort
Da Hye Moon, Jeeyoung Kim, Myoung Nam Lim, et al.
Tuberc Respir Dis. 2021;84(3):188-199.   Published online May 13, 2021
Background: Chronic obstructive pulmonary disease (COPD) is a common chronic respiratory disease with increased prevalence in the elderly. Telomeres are repetitive DNA sequences found at the end of the chromosome, which progressively shorten as cells divide. Telomere length is known to be a molecular marker of aging. This study aimed to assess the relationship between telomere length and the risk...

Role of Krebs von den Lungen-6 (KL-6) in Assessing Hypersensitivity Pneumonitis
Amira Ismail Mostafa, Ayman Elsayed Salem, Heba Allah Moussa Ahmed, et al.
Tuberc Respir Dis. 2021;84(3):200-208.   Published online April 6, 2021
Background: Hypersensitivity pneumonitis (HP) is an increasingly recognized form of diffuse parenchymal lung disease. Krebs von den Lungen-6 (KL-6) is now classified as a human MUC1 mucin protein, and regenerating type II pneumocytes are the primary cellular source of KL-6/MUC1 in the affected lungs of patients with interstitial lung diseases (ILD). Serum KL-6/MUC1 levels have been demonstrated to be useful...

Comparison of Clinical and Radiologic Characteristics between Anthracofibrosis and Endobronchial Lung Cancer
Seo Young Yun, Tae Yun Park
Tuberc Respir Dis. 2021;84(3):209-216.   Published online May 13, 2021
Background: Endobronchial lung cancer (EBLC) and bronchial anthracofibrosis (BAF) share similar symptoms and radiological findings. The aim of this study was to describe clinical and radiological differences between BAF and EBLC, both of which were confirmed by bronchoscopy. Methods: This was a retrospective study of patients with BAF or EBLC from 2008 to 2014. Data were derived from a bronchoscopy registry...

The Effect of the Timing of Dexamethasone Administration in Patients with COVID-19 Pneumonia
Hyun Woo Lee, Jimyung Park, Jung-Kyu Lee, et al.
Tuberc Respir Dis. 2021;84(3):217-225.   Published online March 29, 2021
Background: Despite the proven benefits of dexamethasone in hospitalized coronavirus disease 2019 (COVID-19) patients, the optimum time for the administration of dexamethasone is unknown. We investigated the progression of COVID-19 pneumonia based on the timing of dexamethasone administration. Methods: A single-center, retrospective cohort study based on medical record reviews was conducted between June 10 and September 21, 2020. We compared the...

Diagnostic Accuracy of the Quidel Sofia Rapid Influenza Fluorescent Immunoassay in Patients with Influenza-like Illness: A Systematic Review and Meta-analysis
Jonghoo Lee, Jae-Uk Song, Yee Hyung Kim
Tuberc Respir Dis. 2021;84(3):226-236.   Published online May 13, 2021
Background: Although the Quidel Sofia rapid influenza fluorescent immunoassay (FIA) is widely used to identify influenza A and B, the diagnostic accuracy of this test remains unclear. Thus, the objective of this study was to determine the diagnostic performance of this test compared to reverse transcriptase-polymerase chain reaction. Methods: A systematic literature search was performed using MEDLINE, EMBASE, and the Cochrane...

Comparative Performance of Line Probe Assay (Version 2) and Xpert MTB/RIF Assay for Early Diagnosis of Rifampicin-Resistant Pulmonary Tuberculosis
Raj Narayan Yadav, Binit Kumar Singh, Rohini Sharma, et al.
Tuberc Respir Dis. 2021;84(3):237-244.   Published online March 3, 2021
Background: The emergence of drug-resistant tuberculosis (TB), is a major menace to cast off TB worldwide. Line probe assay (LPA; GenoType MTBDRplus ver. 2) and Xpert MTB/RIF assays are two rapid molecular TB detection/diagnostic tests. To compare the performance of LPA and Xpert MTB/RIF assay for early diagnosis of rifampicin-resistant (RR) TB in acid-fast bacillus (AFB) smear-positive and negative sputum...
