AIMS To evaluate the histological characteristics differentiating chronic hypersensitivity pneumonitis (chronic HP) with a usual interstitial pneumonia (UIP)-like pattern from idiopathic pulmonary fibrosis (IPF)/UIP. METHODS AND RESULTS Surgical lung biopsy specimens from 22 patients with chronic HP diagnosed as having a UIP-like pattern upon histological(More)
A 42-year-old man was admitted to our hospital, complaining of dyspnea and cough for six months. Chest CT demonstrated thickening of the bronchial walls and some centrilobular nodules. From the laboratory data and the clinical course, he was first suspected to have bronchial asthma. However, it was necessary to rule out bronchiolitis due to other causes,(More)
The epithelial alteration in interstitial pneumonias is one of the repair processes at the sites of disease activity. Regenerative epithelial cells may participate in remodeling of the lung. To determine the phenotype of regenerative epithelial cells in usual interstitial pneumonia (UIP) and nonspecific interstitial pneumonia (NSIP), the expression of Clara(More)
An understanding of the diagnostic performance of interferon-gamma release assays (in terms of parameters such as specificity, positive predictive value, and likelihood ratio) is important in the diagnosis of active tuberculosis in elderly Japanese patients because the high proportion of a prior history of tuberculosis among these patients can lead to(More)
BACKGROUND Clinical evaluation to differentiate the characteristic features of pulmonary fibrosis and emphysema is often difficult in patients with combined pulmonary fibrosis and emphysema (CPFE), but diagnosis of pulmonary fibrosis is important for evaluating treatment options and the risk of acute exacerbation of interstitial pneumonia of such patients.(More)
In the respiratory field, chronic pulmonary aspergillosis, such as chronic necrotizing pulmonary aspergillosis (CNPA) or aspergilloma, is important. We examined the efficacy and safety of short- and long-term itraconazole (ITCZ) administration, involving a switch from injection to an oral preparation, in patients with CNPA. In all hospitals participating in(More)
KL-6 is a high-molecular-weight sialylated glycoprotein, classified as a cluster 9 pulmonary cell antigens, and is a sensitive marker for the clinical diagnosis of interstitial pneumonia and its activity, especially in the acute phase. Additionally, it is necessary to diagnosis that patient was not pneumothirax, pulmonary thromboembolism and heart failure.(More)
OBJECTIVES To clarify clinical features of M. kansasii pulmonary disease in women. METHODS We performed a retrospective analysis of M. kansasii pulmonary disease in women compairing with that in men. We focused on 8 female cases of M. kansasii pulmonary disease during the past 7 years from June 1998 to August 2005. RESULTS The cases of M. kansasii(More)
Aspergillosis occurs as an opportunistic infection, and is known as the disease whose diagnosis and treatment are particularly difficult. Japan's first guidelines for the diagnosis and management of invasive fungal infection were revised in 2007, and it is expected that the guidelines may encourage the standardization of the management of fungal infection.(More)
BACKGROUND Chronic pulmonary aspergillosis (CPA) has been accepted the criteria for the diagnosis of pulmonary Aspergillus infection. Whereas, either pathophysiology or signs of CPA remains still controversial. METHODS In this study, we histopathologically investigated 25 specimens of CPA, surgically resected. RESULTS 21 (84 %) of that comprised male.(More)
