  • Objective : In order to know the antibacterial effects of Kyungok-go against Mycobacteria tuberculosis, Methods : In this study, I inverstigated these effects in terms of combination of other antibiotics with and without Kyungok-go on several different media conditions. Results: On Ogawa medium, Kyungok-go of the $10{\mu}/ml$ concentration showed the anti-Mycobacteria tuberculosis activity against antibiotic drug-sensitive strain. On Middle-blue medium, Kyungok-go of the $10{\mu}/ml$ concentration showed the anti-Mycobacteria tuberculosis activity against antibiotic drug-sensitive strain. Kyungok-go showed the anti mycobacteria tuberculosis activity with the meaningful result above a certain concentration. The resistance against M, tuberculosis as the concentration of Kyungok-go was decreased significantlly on the high concentration($500{\mu}/ml$) When rifampicin and Kyungok-go were used together, the resistance was decreased with the statistical significance as to the persistant antibacterial effect against M. tuberculosis, When ciprofloxacin and Kyungok-go were used together, the resistance was decreased with the statistical significance as to the persistant antibacterial effect against M. tuberculosis, The combination of treatment, Kyungok-go with both rifampicin and ciprofloxacin, showed much better antibacterial effect against M, tuberculosis than antibiotics alone. Conclusions : This study shows that Kyungok-go has antibacterial effect against M. tuberculosis and in the combination of treatment, Kyungok-go with antibiotics, showed much better antibacterial effect against M. tuberculosis than antibiotics alone,.

  • Background: Diagnostic methods for pulmonary tuberculosis (TB) have recently advanced. The aim of this study was to evaluate the changes in TB diagnostic tests that prompted the initiation of anti-TB treatment over time in South Korea, an industrialized country with an intermediate TB burden. Methods: Patients diagnosed with pulmonary TB in the first halves of 2005 and 2013 at a tertiary referral hospital were included. Diagnostic methods that prompted the initiation of anti-TB treatment were compared between the 2 groups of patients. Results: A greater proportion of patients were diagnosed with pulmonary TB using bronchoscopy in 2013 than in 2005 (26.7% vs. 6.6%, respectively; p<0.001), while the proportion of patients clinically diagnosed with pulmonary TB was lower in 2013 than in 2005 (24.7% vs. 49.0%, respectively; p<0.001). Additionally, more patients started anti-TB treatment based on positive polymerase chain reaction (PCR) results for Mycobacterium tuberculosis DNA in 2013 than in 2005 (47.3% vs. 7.9%, respectively; p<0.001). Conclusion: The initiation of treatment for pulmonary TB in South Korea has become more frequently based on PCR and the use of bronchoscopic specimens.

  • Alveolar epithelial cells have been functionally implicated in Mycobacterium tuberculosis infection. This study investigated the role of ursolic acid (UA)-a triterpenoid carboxylic acid with potent antioxidant, anti-tumor, anti-inflammatory, and anti-tuberculosis properties in mycobacterial infection of alveolar epithelial A549 cells. We observed that M. tuberculosis successfully entered A549 cells. Cytotoxicity was mediated by nitric oxide (NO). A549 toxicity peaked along with NO generation 72 h after infection. The NO generated by mycobacterial infection in A549 cells was insufficient to kill mycobacteria, as made evident by the mycobacteria growth indicator tube time to detect (MGIT TTD) and viable cell count assays. Treatment of mycobacteria-infected cells with UA reduced the expression of inducible nitric oxide synthase, NO generation, and eventually improved cell viability. Moreover, UA was found to quench the translocation of the transcription factor, nuclear factor kappa B (NF-${\kappa}B$), from the cytosol to the nucleus in mycobacteria-infected cells. This study is the first to demonstrate the cytotoxic role of NO in the eradication of mycobacteria and the role of UA in reducing this cytotoxicity in A549 cells.

  • Purpose: Tuberculosis (TB) remains a problem in the community. TB patients usually experience malnutrition, which is characterized by both decreased body weight (BW) and body fat percentage (BFP). Leptin, an important regulator of BW, also plays an important role in cellular immunity, which is integral to defense against Mycobacterium tuberculosis infection. We analyzed the effect of an anti-TB treatment regimen on the leptin level, BW, and BFP of children with TB. Methods: The design of this study was a group interrupted time series. The subjects were children with probable TB according to clinical criteria based on an Indonesian scoring system adopted from the Consensus of Expert Panel. BW; BFP; energy intake; fat and protein intake; and leptin levels before, 2 months after (intensive phase), and 6 months after (continuation phase) anti-TB treatment, were measured. About 40 children, aged 5-14 years, participated in this study. Results: The BW, BFP and leptin level increased from before treatment to after completion of the intensive phase and still showed an increased during the continuation phase: BW 18.65 kg, 19.75 kg, and 20.85 kg; BFP 18.3%, 19.5%, and 20.2%; and leptin level 1.9 mg/dL, 3.07 mg/dL, and 3.4 mg/dL, respectively (P<0.01). Conclusion: Leptin level, BW, and BFP increased throughout the course of anti-TB treatment, compared with pretreatment values. Further research is needed to compare the results with data for healthy children.

  • 연구배경 : 폐결핵의 치료경과 중에 원활하게 치효에 성공하는 예는 대개 도말이 1~2개월 먼저 음전하고 그 후에 배양도 음전하며 그 후 계속해서 음성상태를 유지한다. 그런데, 배양이 도말보다 먼저 음전되는 도말양성 배양음성 현상을 임상에서 볼 수 있고, 이런 예 중에서도 흔하지는 않으나 특히, 배양은 치료개시 후 4개월 이전에 음전되었더라도 도말이 치료개시 후 6개월을 초과하여 지속적인 양성을 보이는 경우에는 임상적으로 치료실패여부 및 약제변경여부를 판단하는데 어려움이 있다. 이에 본 연구는 일차 항결핵제로 치료개시 후 6개월을 초과하여 지속적인 도말양성 배양음성 현상을 보이는 예 중에 일차 항결핵제로 치료종결한 예를 대상으로 임상적 특성, 치료종결 후의 임상성적 그리고 문헌고찰과 함께 보고하여 임상 진료에 참고가 되고자 하였다. 방 법 : 국립마산결핵병원에서 1995년 1월부터 2000년 12월 사이에 치료개시 후 6개월을 초과하여 지속적인 도말양성 배양음성 현상을 보였고, 일차 항결핵제로 치료종결된 21예를 대상으로 전체환자의 흉부방사선 소견을 비롯한 임상적 특성과 치료종결 후 재발율을 포함한 임상 성적을 조사하고, 재발군과 비재발군으로 분류하여 각 군의 임상적 특성의 차이가 있는지를 확인하였다. 그리고 투약기간의 연장여부, 내성약제 수, 과거력 수, 흉부 방사선 소견상 병변의 크기에 따른 재발율을 비교하고 각각의 변수가 재발에 영향을 주는지를 확인하였다. 결 과 : 전체 대상 환자는 총 21예로 남자가 17예, 여자가 4예 였고, 20세부터 60세까지의 연령분포를 보였으며, 평균 나이는 44.2세 였다. 평균 내성 약제 수는 1제였다. 사용한 항결핵제는 INH, RFP, EMB, PZA 네가지 약제에 SM이나 KM이 첨가된 경우가 6예 있었고 INH, RFP, EMB 세 가지 약제만으로 처음부터 투약된 경우가 1예 있었다. 평균 13.3개월의 투약을 하였다. 배양검사상 대상 환자 모두 3.1개월 이내에 음전되었으며, 투약기간 동안 계속하여 도말검사에서 양성을 보인 3예를 제외한 18예의 도말검사상 평균 음전기간은 9.5개월 이었다. 흉부 방사선 소견상 1예를 제외한 20예에서 공동성 병변을 보였고, 확장병변이 13예(61.9%)로 가장 많았고, 중등병변이 7예(33.3%) 였으며, 국소병변이 1예 있었다. 치료개시 후 20~24주 경의 흉부 방사선 사진과 치료 개시 때의 사진을 비교한 결과 모든 예에서 호전을 보였다. 치료종결 후 평균 15.2개월의 추적관찰 기간 중 4예의 재발이 있어 재발율은 19% 였으며, 재발의 시기는 모두 치료종결 후 3개월에서 4개월 사이에 발생되어 치료 종결 후 재발시기는 평균 14.1주 였다. 14예의 신환 중 1예의 재발이 있어 재발율이 7.1%였고, 두 번째 치료를 하는 4예에서는 재발이 없었고, 세 번째, 네 번째, 다섯 번째 치료를 하는 나머지 3예는 모두 재발하여 과거력의 수에 따른 재발율은 통계적으로 유의한 차이를 보였다(p<0.01). 재발군 1예에서 4.3개월의 투약기간 연장이 있었고, 비재발군 17예 중 11예에서 평균 4.5개월의 투약기간이 연장되었으나 투약기간의 연장여부가 재발에 영향이 없는 것으로 나타났다(odds ratio, 95% 신뢰구간 0.18, 2.15). 결 론 : 투약 개시 후 6개월올 초과하는 도말양성 배양음성 현상은, 의사가 지속적인 도말양성을 치료실패로 잘못 해석하거나 부적절한 치료처방을 할 가능성이 있으므로, 지속적인 객담 도말양성 배양음성 현상의 임상적 중요성을 인식하는 것이 중요하겠으며, 투약 20~24주의 방사선학적 호전을 근거로 일차 항결핵제를 유지하고자 하는 경우에는 투약기간의 연장은 필요치 않으며, 과거력이 2회 이상인 경우에는 재발에 대한 세심한 관심이 있어야 한다.

  • Since tuberculosis (TB) remains a major global health concern and the incidence of multi-drug resistant (MDR)-TB is increasing globally, new modalities for the detection of TB and drug resistant TB are needed to improve TB control. The Xpert MTB/RIF test can be a valuable new tool for early detection of TB and rifampicin resistance, with a high sensitivity and specificity. Late-generation fluoroquinolones, levofloxacin, and moxifloxacin, which are the principal drugs for the treatment of MDR-TB, show equally high efficacy and safety. Systemic steroids may reduce the overall TB mortality attributable to all forms of TB across all organ systems, although inhaled corticosteroids can increase the risk of TB development. Although fixed dose combinations were expected to reduce the risk of drug resistance and increase drug compliance, a recent meta-analysis found that they might actually increase the risk of relapse and treatment failure. Regarding treatment duration, patients with cavitation and culture positivity at 2 months of TB treatment may require more than 6 months of standard treatment. New anti-TB drugs, such as linezolid, bedaquiline, and delamanid, could improve the outcomes in drug-resistant TB. Nontuberculous mycobacterial lung disease has typical clinical and immunological phenotypes. Mycobacterial genotyping may predict disease progression, and whole genome sequencing may reveal the transmission of Mycobacterium abscessus. In refractory Mycobacterium avium complex lung disease, a moxifloxacin-containing regimen was expected to improve the treatment outcome.

  • Tuberculosis is a disease with high morbidity and mortality in children worldwide. Despite the decrease in the incidence of tuberculosis in Korea, more than 30,000 new patients are diagnosed each year. Active tuberculosis is less frequent in children compared to adults but the risk of miliary tuberculosis and CNS tuberculosis is much higher. The diagnosis of tuberculosis in children and adolescents is difficult due to the nonspecific symptoms upon presentation. Diagnostic work up is based on the confirmation of tuberculosis infection by tuberculin skin test, abnormal radiologic findings, and contact with an adult with active tuberculosis. Anti-tuberculosis medications are prescribed according to the drug susceptibility of the index patient. Latent tuberculosis infection plays an important role in adult tuberculosis by reactivation. Thus, it is critical to accurately diagnose latent tuberculosis in children to prevent reactivation in adulthood. Korean guidelines for diagnosis and treatment of tuberculosis in children and adolescents provide evidence based recommendations in the optimal diagnosis and treatment for active and latent tuberculosis in children and adolescents based on the current Korean situation.

  • Background and Objective: The tuberculous lymphadenitis of neck is one of the most common extra-pulmonary tuberculosis in Korea. Although the incidence of pulmonary tuberculo-sis has decreased recently, that of cervical tuberculous lymphadenitis has not decreased. In spite of great efforts and diversity of study, the exact criterias of diagnosis and optimal therapeutic methods of cervical tuberculous lymphadenitis have been the subject of much debate and still remain unclear. So we intend to enucleate clinical manifestations and suggest the optimal therapeutic manners. Material : The 483 cases, diagnosed as cervical tuberculous lymphadenitis by fine needle aspiration biopsy during the past 10 years from Jan. 1987 to Dec. 1996 Method : Retrospective study Results 1) The overall rate of tuberculous cervical lymphadenitis was 23.4% of neck mass. 2) Incidence ratio of male to female was 1:2.7 3) The frequent location of tuberculous lymphadenitis was posterior cervical area, supraclavicular area, jugular chain in order. 4) The response rate of medical treatment in tuberculous cervical lymphadenitis was 84.9%. 5) The duration of medical treatment in remissioned group was 18.6 months in average. 6) Surgical intervention was needed in 15.1%. 7) The duration of post operative medical treatment was 18.4 months in average. Conclusion : Tuberculous cervical lymphadenitis is prevalent in women, age of 20-40 years and mainly involve posterior cervical area. Fine needle aspiration biopsy is a very useful method for early detection of cervical tuberculous lymphadenitis. After diagnosis is made, anti-tuberculosis medication is recommended for more than 18 months. Unless the size of neck mass is decreases inspite of the thorough anti-tuberculosis medication for more than 1 month or if complication like as abscess or fistula occurs, surgery is needed with post operative medical treatment for more than 12 months.

  • Tuberculosis (TB) is one of the largest health problems in the world today. And the incidence of nontuberculous mycobacteria (NTM) lung disease appears to be increasing worldwide. Recently, an automated, nucleic acid amplification assay for the rapid detection of both Mycobacterium tuberculosis and rifampin resistance was developed (Xpert MTB/RIF). And fixed-dose combinations of anti-TB drugs and linezolid have been introduced in the treatment of TB. And new NTM species, named Mycobacterium massiliense, which is very closely related to Mycobacterium abscessus was reported. In this review, these recent advances in the diagnosis and treatment of TB and clinical characteristics of M. massiliense lung disease are discussed.
