BACKGROUND Pulmonary cachexia is common in advanced chronic obstructive pulmonary disease (COPD), culminating in exercise intolerance and a poor prognosis. Ghrelin is a novel growth hormone (GH)-releasing peptide with GH-independent effects. The efficacy and safety of adding ghrelin to pulmonary rehabilitation (PR) in cachectic COPD patients were(More)
It is difficult to distinguish pulmonary disease due to Mycobacterium avium complex (MAC) from that due to other mycobacteria, such as Mycobacterium tuberculosis and Mycobacterium kansasii. We developed an enzyme immunoassay (EIA) for diagnosis of MAC pulmonary diseases that uses glycopeptidolipid (GPL) antigens specific for MAC, and we used it for(More)
BACKGROUND The aim of this substudy of the ghrelin treatment, multicenter, randomized, double-blind, placebo-controlled trial was to investigate the effects of ghrelin administration on exercise capacity and the underlying mechanisms in underweight patients with chronic obstructive pulmonary disease (COPD) using cardiopulmonary exercise testing. METHODS(More)
BACKGROUND Exogenous lipoid pneumonia is a rare disease caused by aspiration or inhalation of oily substances. CASE PRESENTATION A 66-year-old male with dry cough (Case 1) and a 38-year-old female with shortness of breath (Case 2) demonstrated ground-glass opacities on chest computed tomography and were diagnosed with lipoid pneumonia based on the(More)
The present authors have previously reported the usefulness of a serodiagnostic test to detect serum glycopeptidolipid (GPL) core antibody in diagnosing Mycobacterium avium complex (MAC) lung disease in immunocompetent patients. The aim of the present study was to investigate correlations between the levels of antibody against GPL core and chest computed(More)
Infection and transmission of multidrug-resistant Mycobacterium tuberculosis (MDR-Mtb) and extensively drug-resistant M. tuberculosis (XDR-Mtb) is a serious health problem. We analyzed a total of 1,110 Mtb isolates in Osaka Prefecture and neighboring areas from April 2000 to March 2009. A total of 89 MDR-Mtb were identified, 36 (48.5%) of which were(More)
TAKE-HOME SUMMARY Personalized pulmonary rehabilitation including occupational therapy improves the prognosis of patients with advanced COPD. PURPOSE We previously reported that patients with chronic obstructive pulmonary disease (COPD) exhibit three exercise-induced life-threatening conditions: hypoxemia, sympathetic overactivity, and respiratory(More)
To understand the mechanism of exertional dyspnea, we postulated that, despite hyperoxia during exercise, patients with idiopathic pulmonary fibrosis (IPF) might not regulate exertional acidosis by ventilatory compensation to stop exercise. The exercise responses during 30% O(2) or compressed air (CA) were examined in 13 patients with IPF. The PaO(2),(More)
A substudy of ghrelin treatment in a multicenter trial previously revealed that administration of ghrelin improves the exercise capacity of underweight COPD patients. To clarify exertional dyspnea more precisely, exploratory analysis was conducted on data from the substudy. Of 20 underweight COPD patients who were randomized to pulmonary rehabilitation with(More)
BACKGROUND Tiotropium partially relieves exertional dyspnea and reduces the risk of congestive heart failure in chronic obstructive pulmonary disease (COPD) patients. However, its effect on the sympathetic activation response to exercise is unknown. AIMS This study aimed to determine whether tiotropium use results in a sustained reduction in sympathetic(More)
