  • 연구배경: 객담 도말 및 배양 검사나 방사선학적 검사 등의 기존의 결핵 진단 방법은 낮은 민감도와 진단까지 소요되는 기간이 길다는 단점이 있어서 결핵의 조기 진단 및 치료에 제한점이 있었다. 최근에 혈청학적 진단 방법의 하나로 개발된 immunochromatographic assay 기구들이 소개되고, 외국에서 비교적 높은 진단율를 보여, 결핵 유병율이 높은 국내에서 그 유용성을 평가하고, 질병 양상에 따른 차이점을 조사하여, 기존의 결핵 진단 방법들의 문제점을 해결할 수 있는지 알아보고자하였다. 연구방법: 환자군을 폐결핵 환자군(36명), 폐외결핵 환자군(3명) 및 두 가지 모두 이환된 군(22명)으로 나누었으며, 대조군은 과거 결핵 병력이 있는 비활동성 결핵환자(17명), 결핵이외의 폐질환자(16명) 및 폐질환이 없는 심장 환자(14명)를 대상으로 38kDa 항체를 포함한 ICT tuberculosis 또는 BioSign$^{TM}$TB를 이용하여 혈청화적 검사를 시행하였다. 결 과: ICT tuberculosis를 사용한 경우, 환자군 56명 및 대조군 47명에 대하여 64.3%의 민감도 및 91.5%의 특이도를 나타내었으며, 폐결핵만 있는 환자군에서 76.5%의 민감도를 보여, 폐외 결핵만 있는 환자군(33.3%)나 두 가지 모두 이환된 군(47.4%)에 비하여 더 높은 민감도를 나타내었다(p=0.039). BioSign$^{TM}$TB를 이용한 경우, 환자군 43명 및 대조군 43 명에 대하여 74.4%의 민감도 및 95.3%의 특이도를 보였으며, 폐질환이 없는 환자군에서는 100%의 특이도를 나타내었다. 환자군중에서 초발환자 및 과거 폐결핵 병력이 있는 환자군 사이에는 민감도에 차이가 없었으며, 공동성 폐결핵 환자와 비공동성 폐결핵 환자사이에 검사상 민감도 차이는 통계적으로 유의하지 않았다(73.3% vs. 69.6%, p>0.05). 결 론: 혈청학적 방법의 하나인 immunochromatographic assay 기구는 높은 특이도와 양성 예측도를 보여 임상적 유용성이 기대되나, 상대적으로 낮은 민감도와 음성 예측도를 고려할 때, 단독 사용보다는 기존 방법과의 상보적 사용이 결핵진단에 더 도움이 될 것으로 생각된다.

  • 최신 국제 임상진료지침을 기반으로 한 특발폐섬유증의 진단은 부합하는 임상 소견과 함께 고해상 CT에서 전형적인 상용간질폐렴 소견을 보일 때 조직학적 폐 생검 없이 진단 가능하다. 영상 검사는 특발폐섬유증의 평가 및 진단에 중추적인 역할을 하며, 정확한 진단을 위하여 임상적, 영상의학적 및 병리학적 소견에 대한 다학제 검토의 중요성이 강조된다. 간질성폐이상(interstitial lung abnormality)은 우연히 발견된 영상의학적 이상 소견을 지칭하며, 간질성폐이상과 임상적으로 의미 있는 간질폐질환에 대한 구분은 적절한 임상 평가를 기반으로 이루어져야 한다. 저자들은 이번 종설을 통하여 특발폐섬유증 진단의 최신 지견 및 간질성폐이상에 대한 이해를 도움으로써 미만성 간질폐섬유증 환자의 정확한 진단과 치료 및 예후 증진에 도움이 되고자 한다.

  • Pulmonary siderosis, or Welder's lung disease is an occupational lung disease caused by iron-inhalation. Diagnosis of pulmonary siderosis is based on occupational history of the patient, radiologic findings, and pathologic findings of iron-laden macrophages within lung tissue or broncho-alveolar lavage fluid. We observed a case of a 43 years-old welder diagnosed with pulmonary siderosis via thoracoscopic lung biopsy. Sputum culture along with pathology also identified a non-tuberculotic mycobacterial infection with a sputum culture and the pathologic findings. The patient was treated with anti-tubercular medication and cessation of iron-exposure. And his condition improved within a few months.

  • Microscopic polyangiitis is a systemic small-vessel vasculitis that is associated primarily with necrotizing glomerulonephritis and pulmonary capillaritis. A recurrent and diffuse alveolar hemorrhage due to pulmonary capillaritis is the main clinical manifestation of lung involvement. Recently, and interstitial lung disease that mimics idiopathic pulmonary fibrosis was reported to be rarely associated with microscopic polyangiitis. Here we report two patients with microscopic polyangiitis who showed a honeycomb lung at the time of the initial diagnosis with a brief review of relevant literature.

  • In 2011, a cluster of peripartum patients were admitted to the intensive care unit of a tertiary hospital in Seoul with signs and symptoms of severe respiratory distress of unknown etiology. Subsequent epidemiological and animal studies suggested that humidifier disinfectant (HD) might represent the source of this pathology. Epidemiological studies, animal studies, and dose-response analysis demonstrated a strong association between HD use and lung injuries. The diagnostic criteria for HD-associated lung injury (HDALI) was defined on the basis of the clinical, pathological, and radiological attributes of the patients. The clinical spectrum of HDALI appears to range from asymptomatic to full-blown acute respiratory failure, and some patients have required actual lung transplantation for survival. The overall mortality of the exposed population was not significant, although peripartum patients and children who were admitted to the intensive care unit did show high mortality rates. Persistent clinical findings such as diffuse ill-defined centrilobular nodules and restrictive lung dysfunction were observed in some of the survivors. The findings of this review emphasize the importance of assessment of the level of toxicity of chemical inhalants utilized in a home setting, as well as the need to identify and monitor afflicted individuals after inhalational injury.

  • Published data have shown that the levels of vascular endothelial growth factor (VEGF) and soluble VEGF receptor-1 (sVEGFR-1) in plasma and pleural effusion might be usefulness for lung cancer diagnosis. Here, we performed a prospective study to investigate the utility of VEGF and sVEGFR-1 in bronchoalveolar lavage fluid (BALF) for differential diagnosis of primary lung cancer. A total of 56 patients with solitary pulmonary massed by chest radiograph or CT screening were enrolled in this study. BALF and plasma samples were obtained from all patients and analyzed for VEGF and sVEGFR-1 using a commercially available sandwich ELISA kit. The results showed that the levels of VEGF in BALF were significantly higher in patients with a malignant pulmonary mass compared with patients with a benign mass (P < 0.001). However, no significant difference of sVEGFR-1 in BALF was found between malignant and non-malignant groups (P = 0.43). With a cut-off value of 214 pg/ml, VEGF showed a sensitivity and specificity of 81.8% and 84.2%, respectively, in predicting the malignant nature of a solitary pulmonary mass. Our study suggests that VEGF is significantly increased in BALF among patients with lung cancer than in benign diseases. Measurement of VEGF in BALF might be helpful for differential diagnosis of primary lung cancer.

  • 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.

  • Lung function reportedly declines with age and that this decline is accelerated during disease progression. However, a recent study showed that the decline might peak in the mild and moderate stage. The prognosis of chronic obstructive pulmonary disease (COPD) can be improved if the disease is diagnosed in its early stages, prior to the peak of decline in lung function. This article reviews recent studies on early COPD and the possibility of applying the U.S. Preventive Services Task Force recommendation 2008 and 2015 for early detection of COPD in Korea.
