Air trapping was found in approximately 50% of asymptomatic subjects. The frequency of air trapping increased with age, and its severity increased with age and smoking.

RATIONALE: Neutrophils are key effectors in the host's immune response to sepsis. Excessive stimulation or dysregulated neutrophil functions are believed to be responsible for sepsis pathogenesis. However, the mechanisms regulating functional plasticity of neutrophils during sepsis have not been fully determined. OBJECTIVES: We investigated the role of autophagy in neutrophil functions during sepsis in patients with community-acquired pneumonia. METHODS: Neutrophils were isolated from patients w

Clinicaltrials.gov: NCT01254032.

BACKGROUND: Oral CXC chemokine receptor 2 (CXCR2) antagonists have been shown to inhibit neutrophil migration and activation in the lung in preclinical and human models of neutrophilic airway inflammation. A previous study with danirixin, a reversible CXCR2 antagonist, demonstrated a trend for improved respiratory symptoms and health status in patients with COPD. METHODS: This 26-week, randomised, double-blind, placebo-controlled phase IIb study enrolled symptomatic patients with mild-to-moderat

Acute tumor lysis syndrome (TLS) occurs frequently in hematologic malignancies such as high-grade lymphomas and acute leukemia, which are rapidly proliferating and chemosensitive tumors. It occurs rarely in solid tumors and has never been reported in gastric adenocarcinoma. Typical biochemical findings of acute tumor lysis syndrome are hyperuricemia, hyperkalemia, hyperphosphatemia and hypocalcemia in patients with a malignancy. Rapid changes of these electrolytes may cause cardiac arrhythmia, s

Cigarette smoking is the most important risk factor for obstruction of airflow in chronic obstructive pulmonary disease (COPD). Matrix metalloproteinases (MMPs) or an imbalance between MMPs and their inhibitors, the tissue inhibitors of MMP (TIMPs), is considered to play a role in the pathogenesis of COPD. We investigated whether the MMPs expression or the imbalance between MMPs and TIMP-1 is associated with the amount of cigarette smoking and the FEV1 value, in the lung parenchyma of 26 subject

A new quinolone, zabofloxacin, has now been developed; hence, a non-inferiority trial is needed to compare this new compound with another widely used quinolone to examine its efficacy and safety for the treatment of chronic obstructive pulmonary disease (COPD) exacerbations. This was a prospective, multicenter, double-blind, double-dummy, randomized, controlled, parallel-group, Phase III, non-inferiority clinical trial designed to compare oral zabofloxacin (367 mg once daily for 5 days) with mox

PURPOSE: The efficacy and safety of Chinese herbs for symptomatic treatment of bronchitis is not well established. We evaluated the efficacy and safety of a combination product of seven herbs (HL301) for the treatment of acute bronchitis (AB) and acute exacerbation of chronic bronchitis (AECB) using a randomized, double-blind, placebo-controlled, multicenter trial design. METHODS: A total of 160 patients with AB or with AECB were randomized to receive placebo or one of three doses of HL301 (0.6

연구배경: COPD는 전세계적으로 유병률, 이환율 및 사망률이 급격히 증가하는 질환으로 환자의 삶의 질을 호전 시키고 사회, 경제적인 질병부담을 줄이기 위해 경증 COPD 환자를 조기에 진단하여 적절히 치료하는데 일차진료의사의 역할이 중요하다. 근거중심을 바탕으로 개발된 GOLD와 같은 COPD 진료지침은 이 목적을 위해 유용하나 우리나라의 진료실태가 반영되지 않은 문제점이 있다. 근거중심을 바탕으로 우리나라 진료실정이 반영된 진료지침을 개발하기 위해 우리나라 일차진료의사들의 진료 실태를 조사하여 보고한다. 방법: 진료실태는 웹을 기반으로 COPD의 진단, 치료, 위험인자, 교육, 진료지침에 대한 25개의 설문을 포함 제작하였고 총 217명의 일차진료의사가 설문조사에 동의하고 참여하였다. 참여자의 의사경력은 평균 17.7년이며 76.5%가 내과를 전공하였고 지역적으로는 63.6%가 서울, 경기지역에서 진료를 하고 있었다. 결과: 비교적 높은 비율(61.8%)로 폐기능검사기를 보유하고

Background: The incidence of chronic obstructive pulmonary disease (COPD) is increasing and the disease is becoming an important cause of morbidity and mortality worldwide. It is important to implement evidence-based guidelines by primary care physicians (PCPs) to establish qualified management of COPD patients. The aim of this survey is to investigate the pattern of COPD management among PCPs and to apply it to the development of Korean COPD guidelines. Methods: A web-based questionnaire was pr

연구배경: 우리나라에서 대체-보완의료가 기관지천식의 환자에서 광범위하게 사용되어지리라고 추측되고 있다. 그러나 우리나라 성인천식환자에서의 대체-보완의료의 실태는 아직 보고된 바가 없다. 이 연구는 우리나라의 성인천식환자에 있어서 대체-보완의료의 사용실태와 경향을 알아보고자 시행하였다.방 법: 2000년 1월부터 2003년 12월까지 경희대병원에 1회 이상 입원한 병력이 있는 천식 환자를 대상으로 하였으며 설문조사 연구에 동의하는 환자 100명에게 직접면담 하거나 전화를 통해 설문조사를 시행했다. 환자들의 병력은 병록지를 참고로 조사하였다.결 과: 조사환자 100명 중 53명이 대체-보완 의료를 경험하였다. 환자가 치료받은 병원 수가 많을수록 대체-보완의료를 경험한 횟수가 많았으며, 연령 별로는 50대가 가장 많이 대체-보완의료를 경험하였다. 흔히 사용한 대체-보완의료의 종류는 음식 및 건강식품이 35명으로 가장 많았다. 그 다음으로 약초가 28명, 침 요법이 9명, 쑥뜸요법이 6명,
