  • 연구배경 : 흉막박피술은 만성적인 농흉으로 인한 감염 병소의 제거와 감소된 폐기능의 향상을 도모할 목적으로 시행되어져 왔는데, 박피술 후 폐기능이 개선되지 않는 경우도 있어 어떤 군에서 박피술이 유용한 지에 대해 수술 전후의 폐기능 검사를 통해 이를 검토하였다. 방법 : 1990년부터 1996년까지 서울대 병원에서 결핵성 농흉으로 흉막 박피술을 시행받은 37명의 환자를 대상으로 수술 전후의 폐기능검사를 후향적으로 분석하였다. 결과 : 환자군의 남녀비는 29 : 8, 나이의 중앙값은 34세(15-68)였다. 농흉의 발생부터 수술까지의 기간은 1개월에서부터 30년까지 다양했으며, 수술 후 폐기능 검사는 평균 5.4$\pm$2.6 개월에 행해졌다. 1. 전체 환자에서 FVC는 수술 전 2.77$\pm$0.67(L)에서 2.95$\pm$0.81 (L)로 유의하게 증가했다(p=0.02). 2. 40세 이하의 환자 군에서 40세 이상의 환자 군보다 FVC가 유의하게 증가했다(p=0.01). 3. 진단후 4개월 이내 조기 흉막박피술을 시행받은 군에서 진단 4개월 이후 시행받은 군보다 더욱 큰 FVC의 증가를 보였다(p=0.007). 4. 수술 전 폐기능검사에서 FVC가 예상치의 60% 이하로 감소되어 있던 군이 예상치의 60% 이상이었던 군에 비해 수술 후 FVC 의 유의한 증가를 보였다 (p=0.047). 5. 수술 전 흉부 방사선학적 검사상 흉막에 석회화를 동반하지 않은 군이 석회화를 동반한 군에 비해 FVC의 증가가 유의했다(p=0.02). 결론 : 이상의 결과에서 흉막박피술은 전반적으로 환자의 폐기능의 증가를 가져왔으며, 특히 40세 이전의 젊은 환자, 농흉 발생 후 4개월 이내 흉막 박피술을 시행했을 경우, 수술 전 폐활량이 예상치의 60%이하로 감소되었던 경우와 흉막에 석회화를 동반하지 않았을 때가 도움이 되었다.

  • 연구배경: 비만과 폐 기능의 저하는 만성 질환 이환율과 사망률 증가와 관련 있는 것으로 알려져 있다. 하지만 국내에서 체중이나 체질량지수(BMI)의 변화가 폐 기능에 미치는 영향에 대한 연구는 없어 본 연구는 건강증진센터에서 연속적인 검진을 받은 한국인 수검자를 대상으로 체중이나 BMI 변화가 폐 기능 검사(PFT)의 인자들에 미치는 영향에 대해 알아보고자 한다. 방법: 2015년과 2017년에 일개 건강증진센터에서 건강검진을 연속적으로 받은 사람 중 신체계측과 PFT를 모두 시행한 5,032명을 대상으로 체중과 BMI의 변화와 PFT와 연관성을 상관분석 및 t-검정을 통하여 분석하였다. 결과: 체중과 BMI 변화에 따른 PFT 인자들과의 관련성에 있어서 남성에서는 유의미한 차이를 확인할 수 없었고 다만 체중이 증가한 그룹에서 FEV1이 체중이 감소한 그룹에 비해 더 낮은 것으로 확인되었다. 여성에서는 체중과 BMI가 증가한 그룹에서 FEV1/FVC와 FEF25-75%가 체중이 감소한 그룹에 비해 더 낮았고, 체중과 BMI 변화에 따른 PFT 인자들과의 관련성에서 FEV1/FVC와 FEF25-75%가 음의 상관관계를 보여 비만도의 증가에 따라 FEV1/FVC와 FEF25-75%가 낮아지는 것과 관련이 있을 수 있음을 확인하였다. 결론: 본 연구에서는 비만도의 변화에 따라 PFT의 인자들의 변화가 있을 수 있음을 확인하였고 비만의 적절한 관리가 폐 기능에도 긍정적인 영향을 미칠 수 있을 가능성을 확인한 것에 의의가 있다. 향후 대규모 다기관 연구를 통해 지속적인 비만의 관리가 폐 기능 및 폐질환에 미치는 영향에 대한 연구가 필요할 것으로 생각된다.

  • Background: There are limited number of studies that investigate clinical variables instead of chronic obstructive lung disease (COPD) management according to Global Initiative for Chronic Obstructive Lung Disease (GOLD) 2017 classification. The aim of the study was to investigate whether there was a difference between GOLD 2017 classification and spirometric stage in clinical variables in patients with COPD. The data of 427 male patients with stable COPD were investigated retrospectively. Methods: Patients were allocated into combined assessment of GOLD 2017 and spirometric stage. Age, amount of smoking, pulmonary function, modified Medical Research Council (mMRC), incremental shuttle walk test (ISWT), Hospital Anxiety-Depression Scale (HADS), St. George's Respiratory Questionnaire (SGRQ), body mass index (BMI), and fat free mass index (FFMI) were recorded. Results: Seventy-three (17%) patients were in group A, 103 (24%) constituted group B, 38 (9%) were included in group C, and 213 (50%) comprised group D according to the combined assessment of GOLD 2017. Twenty-three patients (5%) were in stage 1, 95 (22%) were in stage 2, 149 (35%) were in stage 3, and 160 (38%) were in stage 4 according to spirometric stage. According to GOLD 2017, age, amount of smoking, mMRC, BMI, FFMI, SGRQ, HADS, forced vital capacity, forced expiratory volume in 1 second ($FEV_1$), and ISWT were significantly different between groups. Ages, amount of smoking, FFMI, BMI, HADS of group A were different from B and D. Smiliar values of $FEV_1$ were found in A-C and B-D. A and C had smiliar ISWT. According to spirometric stage, BMI, FFMI of stage 4 were statistically different. mMRC, ISWT, and SGRQ of stages 3 and 4 were different from other stages, amongst themselves. $FEV_1$ was correlated with mMRC, SGRQ, anxiety scores, BMI, FFMI, and ISWT. Conclusion: This study showed that the GOLD ABCD classification might not represent the severity of COPD sufficiently well in terms of lung function or exercise capacity. The combination of both spirometric stage and combined assessment of GOLD 2017 is important, especially for estimating clinical variables.

  • Background: Chronic obstructive pulmonary disease (COPD) is now regarded as a heterogenous disease, with variable phenotypes. Acute exacerbation of COPD is a major event that alters the natural course of disease. The frequency of COPD exacerbation is variable among patients. We analyzed clinical features, according to the frequency of acute exacerbation in COPD. Methods: Sixty patients, who visited Gyeongsang National University Hospital from March 2010 to October 2010, were enrolled. Patients were divided into two groups, according to their frequency of acute exacerbation. Frequent exacerbator is defined as the patient who has two or more exacerbation per one year. We reviewed patients' medical records and investigated modified Medical Research Council (MMRC) dyspnea scale, smoking history and frequency of acute exacerbation. We also conducted pulmonary function test and 6-minute walking test, calculated body mass index, degree of airway obstruction and dyspnea and exercise capacity (BODE) index and measured CD146 cells in the peripheral blood. Results: The number of frequent exacerbators and infrequent exacerbators was 20 and 40, respectively. The frequent exacerbator group had more severe airway obstruction (forced expiratory volume in one second [$FEV_1$], 45% vs. 65.3%, p=0.001; $FEV_1$/forced vital capacity, 44.3% vs. 50.5%, p=0.046). MMRC dyspnea scale and BODE index were significantly higher in the frequent exacerbator group (1.8 vs. 1.1, p=0.016; 3.9 vs. 2.1, p=0.014, respectively). The fraction of CD146 cells significantly increased in the frequent exacerbator group (2.0 vs. 1.0, p<0.001). Conclusion: Frequent exacerbator had more severe airway obstruction and higher symptom score and BODE index. However, circulating endothelial cells measured by CD146 needed to be confirmed in the future.

  • Background: Combined pulmonary fibrosis and emphysema (CPFE) have different pulmonary function tests (PFTs) and outcomes than idiopathic pulmonary fibrosis (IPF). The intention of this study was to identify unknown differences between CPFE and IPF by a retrospective comparison of clinical data including baseline and annual changes in pulmonary function, comorbidities, laboratory findings, clinical characteristics and cause of hospitalization. Methods: This study retrospectively enrolled patients with CPFE and IPF who had undergone PFTs once or several times per year during a follow-up period of three years. Baseline clinical characteristics and the annual changes in the pulmonary function during the follow-up period were compared between 26 with CPFE and 42 patients with IPF. Results: The baseline ratio of forced expiratory volume in one second to forced vital capacity ($FEV_1$/FVC%) in patients with CPFE was lower than that in patients with IPF ($78.6{\pm}1.7$ vs. $82.9{\pm}1.1$, p=0.041). The annual decrease in $FEV_1$/FVC in the CPFE was significantly higher than in the IPF. The annual decreases in diffusion capacity of carbon monoxide and FVC showed no significant differences between the two groups. The symptom durations of cough and sputum were in the CPFE significantly lower than in the IPF. The serum erythrocyte sedimentation rate level at the acute stage was significantly higher than in the IPF. There were no significant differences in the hospitalization rate and pneumonia was the most common cause of hospitalization in both study groups. Conclusion: The annual decrease of $FEV_1$/FVC was in patients with CPFE significantly higher than in the patients with IPF.

  • 본 연구는 칼텐본을 접목한 흉추가동운동이 폐기능에 미치는 영향을 알아보기 위하여 20대 대학생 20명을 대상으로 4주간 실시하였다. 실험대상자 20명을 대상으로 실험군, 대조군으로 무작위 동공선택방식으로 그룹 배정을 하였다. 실험군은 횡격막 호흡운동 15분과 칼텐본을 적용한 흉추가동운동 15분으로 구성되고, 대조군은 횡격막 호흡운동으로 30분간 훈련하였으며, 두 군의 운동프로그램은 주 3회 4주간 실시하였다. 측정은 폐기능을 측정하여 자료를 분석하였다. 실험 전·후 폐기능을 분석해 보면, 실험군은 TV, IRV에서 유의하게 증가하였으며, 실험후에 두 집단간의 변화검증에서도 TV와 IRV에서 유의한 차이가 나타났다. 본 연구를 통해 칼텐본을 이용한 흉추가동운동이 폐 기능에 더 긍정적인 효과를 주는 것을 알 수 있었다. 앞으로 임상에서 호흡훈련 시 일반적인 호흡훈련에 흉추가동운동을 함께 접목하는 치료방법이 적극적으로 중재되기를 기대하며 다양한 추가운동프로그램의 개발이 필요할 것으로 사료된다.

  • Objective: This study was designed to analyze the clinical features of idiopathic pulmonary fibrosis patients who attended a Korean medicine hospital and the treatment effects through retrospective chart reviews. Methods: The medical records of 82 outpatients who had been diagnosed with idiopathic pulmonary fibrosis and visited the Allergy, Immune, and Respiratory System Department of Kyung Hee Korean Medicine Hospital from 8 January 2015 to 8 January 2021 were retrospectively reviewed. To assess the treatment outcomes, we used the FVC (Forced Vital Capacity), DLCO (Diffusing capacity of the Lung for CO), 6-minute walk test, and HRCT (High Resolution Computed Tomography). Results: The study group consisted of 28 females and 54 males. The median age of the patients was 67.98±11.44 years. The chief complaints were cough (n=51) and dyspnea (n=49). Other frequent symptoms were general weakness (n=8), weight loss (n=4), and a fever (n=2). A total of 77 (93.90%) patients were prescribed Korean herbal medicine, and 52 (63.41%) patients were treated with acupuncture, moxibustion, cupping therapy, ICT, or pharmacopuncture. After treatments, FVC, DLCO, the 6-minute walk test, and HRCT were maintained or worsened slightly. Conclusions: This study presented the characteristics of idiopathic pulmonary fibrosis patients treated by Korean medical therapies, and further studies of Korean medical treatments for idiopathic pulmonary fibrosis patients would be valuable.

  • Background: Radiotherapy is a common treatment option for lung or esophageal cancer, particularly when surgery is not feasible for patients with poor lung function. However, radiotherapy can affect pulmonary function and thereby induce pneumonitis or pneumonia, which can be fatal in patients with respiratory impairment. The purpose of this study is to evaluate if reductions in pulmonary function after radiotherapy can be minimized through simultaneous pulmonary rehabilitation (PR). Methods: In this matched case control study, we retrospectively analyzed patients who had undergone radiotherapy for thoracic malignant disease between January 2018 and June 2019. We analyzed results from pulmonary function tests and 6-minute walking tests (6MWT) conducted within the six months before and after radiotherapy treatment. Results: In total, results from 144 patients were analyzed, with 11 of the patients receiving PR and radiotherapy simultaneously. Of the 133 patients in the control group, 33 were matched with 11 patients in the PR group. Changes in forced expiratory volume in one second (FEV1) and FEV1/forced vital capacity were significantly different between the PR group and the matched control group (240 mL vs. -10 mL, p=0.017 and 5.5% vs. 1.0%, p=0.038, respectively). The median distance of 6MWT in the PR group also increased significantly, from 407.5 m to 493.0 m after radiotherapy (p=0.017). Conclusion: Simultaneous PR improved pulmonary function, particularly in measures of FEV1, and exercise capacity for patients with lung or esophageal cancer even after radiotherapy treatment. These findings may provide an important base of knowledge for further large population studies with long-term follow-up analysis in the identification of the PR's effects during thoracic radiotherapy.

  • 국내 중고교 엘리트 사이클 선수를 대상으로 점진부하 운동 시 유산소반응과 폐환기 반응을 분석하는데 목적을 두었다. 남자 사이클 선수($17{\pm}1$ 세, $175{\pm}5\;Cm$, $70{\pm}9\;kg$) 12명이 신체계측, 점진부하 운동 검사, 폐기능 검사에 참여하였다. 사이클 에르고미터를 이용한 점진부하 운동 중 이들의 최대산소섭취량($VO_2max$)과 최대파워 (Wmax), 환기량, 산소 및 이산화탄소호흡당량($V_E/VO_2$, $V_E/VCO_2$), 호흡율, 일회호흡량 등이 측정되었다. 호흡반응의 시간변인으로 흡기시간(Ti), 호기시간(Te), 일회호흡시간(Tb), 흡기의무사이클(Ti/Tb), 흡기율($V_T$/Ti)이 분석되었다. 폐기능으로는 폐활량, 일초호기량, 일초율, 최대호기량 등이 측정되었다. 선수들은 최대운동시 $57.5{\pm}3.9\;ml{\cdot}kg^{-1}{\cdot}min^{-1}$$VO_2max$, $194.1{\pm}8.6\;beat{\cdot}min^{-1}$의 최대심박수를 보였으며, Wmax 는 평균 452 W에 도달하였다. $VO_2max$은 신체계측 변인들과 상관관계를 보이지 않았다. 대부분의 환기반응은 운동강도가 점차적으로 증가하면서 동반 증가하였다. 운동강도의 증가와 함께 Ti, Te, Tb는 감소하였으며, Ti/Tb는 대략적으로 일정하게 유지되었다. 250 W 이하에서 신장, 체중, 신체질량지수, 체표면적은 $V_T$/Ti 그리고 Ti/Tb 와 높은 상관관계를 나타냈다(p<0.05). 결과적으로, 엘리트 사이클 선수들의 최대유산소능력은 성인에 비해 낮은 것으로 보이며, 이는 성인과 호흡조절 양상이 다른 것으로 추정된다. 신체계측 변인은 $VO_2max$와 상관성이 존재하지 않았다. 호흡반응의 시간 변인은 운동강도 250 W 이하에서만 체격과 연관성을 가지는 것으로 보인다. 흡기율은 어린 선수들의 운동지속시간과 연관 있어 보이지만, 흡기의무사이클은 성인과 유사한 것으로 보인다.
