Asthma is a chronic inflammatory airway disease that is characterized by variable airflow obstruction. The Korean Asthma Study Group of the Korean Academy of Tuberculosis and Respiratory Diseases has recently updated the Korean Asthma Guideline. This review summarizes the updated Korean Asthma Guideline. Asthma prevalence is increasing worldwide, and in Korea. Variable airflow obstruction can be confirmed by bronchodilator response or other tests, and should be established prior to the controller medication. A low-dose inhaled corticosteroid-formoterol is used to alleviate symptoms in all treatment step, and it can be used as a controller as well as reliever in steps 3-5. This approach is preferred, because it reduces the risk of severe exacerbations, compared to the use of short-acting β2-agonist as reliever. In severe asthma, phenotype/endotype based on the underlying inflammation should be evaluated. For type 2 severe asthma, the biologics should be considered.

It is important to discriminate between tuberculosis and tuberculosis-like disease by Mycobacteria other than tuberculosis in the serodiagnosis of tuberculosis. But because common antigens share among Mycobacteria, their antigenicities to human are similar. Therefore degree of cross-reactivity of antibody in the sera of patients with tuberculosis between M. tuberculosis and Mycobacteria other than tuberculosis should be checked to increase the specificity in the serodiagnosis of tuberculosis. The activity levels of IgG antibody in the sera of 106 patients confirmed as active pulmonary tuberculosis and 30 normal healthy control person to the pressate extract antigen (TE, BE, AE, and FE antigen) from M. tuberculosis, M. bovis, M. avium, and M. fortuitum were measured by enzyme-linked immunosorbent assay and the crossreactivity of IgG antibody with mycobacterial species was analysed. The results were as follows; 1. The activity level(O.D. at 492nm) of IgG to TE antigen in sera of patients with pulmonary tuberculosis was $0.228{\pm}0.167$ in minimal tuberculosis; moderately advanced, $0.556{\pm}0.616$; far advanced, $1.116{\pm}0.651$ and $0.315{\pm}0.245$ in miliary tuberculosis. 2. The activity level (O.D. at 492nm) of IgG to BE antigen in sera of patients with pulmonary tuberculosis was $0.190{\pm}0.162$ in minimal tuberculosis; moderately advanced, $0.337{\pm}0.361$; far advanced, $0.713[\pm}0.460$ and $0.204{\pm}0.162$ in miliary tuberculosis. 3. The activity level (O.D. at 492nm) of IgG to AE antigen in sera of patients with pulmonary tuberculosis was $0.165{\pm}0.114$ in minimal tuberculosis; moderately advanced, $0.392{\pm}0.494$; far advenced, $0.751{\pm}0.512$ and $0.233{\pm}0.191$ in miliary tuberculosis. 4. The activity level (O.D. at 492nm) of IgG to FE antigen in sera of patients with pulmonary tuberculosis was $0.280{\pm}0.227$ in minimal tuberculosis; moderately advanced, $0.460{\pm}0.564$ ; far advanced, $0.845{\pm}0.573$ and $0.257{\pm}0.103$ in miliary tuberculosis. 5. The activity level (O.D. at 492nm) of IgG in sera of healthy control person was $0.126{\pm}0.084$ to TE antigen. $0.105{\pm}0.041$ to BE antigen, $0.103{\pm}0.052$ to AE antigen, and $0.095{\pm}0.061$ to FE antigen. 6. Degree of correlation(r) in activity level of IgG between TE antigen and BE antigen was 0.905 ; between TE antigen and AE antigen, 0.760; between TE antigen and FE antigen, 0.790, and between AE antigen and FE antigen, 0.945. 7. As O.D. above 0.200 was determined positive for the serodiagnosis of pulmonary tuberculosis, the sensitivity and specificity in ELISA using TE antigen were 80% and 87% respectively, whereas in the case of using BE antigen, 66% and 100%; in the case of using AE antigen, 62% and 100%, and in the case of using FE antigen, 72% and 93%, respecitively.

Chronic obstructive pulmonary disease (COPD) results in high morbidity and mortality among patients both domestically and globally. The Korean clinical practice guideline for COPD was revised in 2014. It was drafted by the members of the Korean Academy of Tuberculosis and Respiratory Diseases, as well as participating members of the Health Insurance Review and Assessment Service, Korean Physicians' Association, and Korea Respiration Trouble Association. This revised guideline covers a wide range of topics, including the epidemiology, diagnosis, assessment, monitoring, management, exacerbation, and comorbidities of COPD in Korea. We drafted a guideline on COPD management by performing systematic reviews on the topic of management with the help of a meta-analysis expert. We expect this guideline will be helpful medical doctors treating patients with respiratory conditions, other health care professionals, and government personnel in South Korea.

A mixed infection of Mycobacterium abscessus subsp. abscessus (Mab) and Mycobacterium tuberculosis (MTB) in the lung is an unusual clinical manifestation and has not yet been reported. A 61-year-old woman had been treated for Mab lung disease and concomitant pneumonia, and was diagnosed with pulmonary tuberculosis (PTB). Despite both anti-PTB and anti-Mab therapy, her entire left lung was destroyed and collapsed. She underwent left pneumonectomy and received medical therapy. We were able to successfully treat her mixed infection by pneumonectomy followed by inhaled amikacin therapy. To the best of our knowledge, thus far, this is the first description of a mixed Mab and MTB lung infection.

연구배경 : 기관지 결핵은 폐결핵의 특이형태 또는 일종의 합병증으로 알려져 있으며 진단 및 치료에 많은 문제점이 있어왔으나 전체적인 발생율은 명확히 알려져 있지않다. 저자들은 활동성 폐결핵 환자들을 대상으로 전향적으로 기관지 내시경을 시행하여 기관지 결핵의 빈도 및 임상상을 연구하였다. 방법 : 1995년 3월 부터 1996년 2월까지 충남대학교병원 내과에 내원하여 활동성 폐결핵으로 진단받은 환자 103명을 대상으로 폐결핵 진단후 2주 이내에 기관지 내시경을 시행하였고 이들을 대상으로 임상 증상과 흉부 방사선 검사 및 기관지 세척액 항산균 검사, 폐기능검사 등을 시행하였다. 결과 : 활동성 폐결핵 환자 103명 중 기관지 결핵환자는 55명으로 기관지 결핵의 동반율은 53.4% 였고 이중 남자는 32명으로 43.8%의 발병율을, 여지는 23명으로 76.7%의 발병율을 보였다. 가장 흔한 증상은 기침, 객담, 발열 등의 비특이적 증상이었고 진찰소견상 수포음, 감소된 호흡음 및 천명이 청진되었다. 기관지경상의 기관지결핵 아형은 7가지 모두가 관찰되었으며 부종-충혈형이 가장 흔히(32.7%) 관찰되었고, 만성 비특이성 기관지염형 및 섬유성 협착형의 순으로 관찰되었다. 이들 아형과 흉부 방사선 소견 및 결핵의 진행정도와는 무관하였고, 우폐의 침범율이 좌폐보다 높았으며, 좌상엽이 가장 호발하는 부위였고, 우상엽, 기관의 순으로 침범된 소견을 보였다. 또한 폐기능검사 소견상 특이한 점은 없었고, 폐결핵만 존재한 경우와 차이가 없었다. 이들에서 객담 및 기관지 세척액 항산균 도말 검사 양성은 72.7% 이었다. 결론 : 이상의 결과로서 폐결핵환자에서 기관지 결핵의 병발은 이전에 알려진 것보다 훨씬 높으며, 페결핵의 진단시 특히 항산균 도말양성시 기관지 내시경 검사의 시행이 고려되어야 할 것으로 생각된다.

Background: Effective treatment of fluoroquinolone-resistant multidrug-resistant tuberculosis (FQr-MDR-TB) is difficult because of the limited number of available core anti-TB drugs and high rates of resistance to anti-TB drugs other than FQs. However, few studies have examined anti-TB drugs that are effective in treating patients with FQr-MDR-TB in a real-world setting. Methods: The impact of anti-TB drug use on treatment outcomes in patients with pulmonary FQr-MDR-TB was retrospectively evaluated using a nationwide integrated TB database (Korean Tuberculosis and Post-Tuberculosis). Data from 2011 to 2017 were included. Results: The study population consisted of 1,082 patients with FQr-MDR-TB. The overall treatment outcomes were as follows: treatment success (69.7%), death (13.7%), lost to follow-up or not evaluated (12.8%), and treatment failure (3.9%). On a propensity-score-matched multivariate logistic regression analysis, the use of bedaquiline (BDQ), linezolid (LZD), levofloxacin (LFX), cycloserine (CS), ethambutol (EMB), pyrazinamide, kanamycin (KM), prothionamide (PTO), and para-aminosalicylic acid against susceptible strains increased the treatment success rate (vs. unfavorable outcomes). The use of LFX, CS, EMB, and PTO against susceptible strains decreased the mortality (vs. treatment success). Conclusion: A therapeutic regimen guided by drug-susceptibility testing can improve the treatment of patients with pulmonary FQr-MDR-TB. In addition to core anti-TB drugs, such as BDQ and LZD, treatment of susceptible strains with later-generation FQs and KM may be beneficial for FQr-MDR-TB patients with limited treatment options.
