BACKGROUND: Mechanisms that elicit mucosal Th17 cell responses have been described, yet how these cells are sustained in chronically inflamed tissues remains unclear. OBJECTIVE: We sought to understand whether the maintenance of lung Th17 inflammation requires environmental agents in addition to antigen, and to identify the lung antigen-presenting cell types (APCs) that sustain the self-renewal of Th17 cells. METHODS: Animals were repeatedly exposed to aspiration of ovalbumin alone, or together with environmental adjuvants, including extracts of common house dust (HDE), to test their role in maintaining lung inflammation...

Studies have shown that blood bubbles may be detectable and there is ultrasonic evidence of acute interstitial lung edema even after diving without protocol violation. Macrophages play a central role in the inflammation, and macrophage polarization is closely related to the pathogenesis some lung diseases. Available findings indicate that decompression may induce the production of pro-inflammatory cytokines, chemokines, and adhesion molecules in the blood and tissues, which are associated with the macrophage polarization, and hyperbaric treatment may exert therapeutic effects on decompression related diseases via regulating these factors...

A 66-year-old woman with a history of interstitial lung disease presented with a 3-month history of dropped head syndrome (DHS), followed by camptocormia and extremity weakness. A clinical examination revealed Raynaud phenomenon, arthralgia, distal skin sclerosis, and microbleeds in the nailfold capillaries. An anti-Ku antibody test was positive. A muscle biopsy revealed inflammatory myopathy with rimmed vacuoles (RVs). The diagnosis of scleroderma-polymyositis (SSc-PM) overlap syndrome was made. RVs on a muscle biopsy in a patient with inflammatory myositis involving axial muscles may be seen either in inclusion body myositis or SSc-PM overlap syndrome...

Respiratory syncytial virus (RSV) is the leading cause of bronchiolitis and hospitalization that lead to high morbidity and mortality among young infants. T helper 17 (Th17) cells and regulatory T cells (Tregs) play essential roles in the pathogenesis of autoimmune, cancer, and inflammatory diseases. However, whether changes in T-cell subsets are related to the systemic immune responses in RSV-caused bronchiolitis merit further investigation. Three-week-old Sprague Dawley (SD) rats were randomly divided into the normal control (NC) and RSV bronchiolitis (RSV-B) groups...

OBJECTIVES: Chemotherapy-related acute exacerbation (AE) of interstitial lung disease (ILD) is observed in certain patients with non-small cell lung cancer (NSCLC) who have ILD. Although the prognosis of AE-ILD is extremely poor, there are no established risk factors for its occurrence. Therefore, we retrospectively investigated whether high-resolution computed tomography (HRCT) findings could identify risk factors for AE-ILD. MATERIALS AND METHODS: Between January 2005 and December 2016, 35 patients with NSCLC who received chemotherapy at Hiroshima University Hospital and were diagnosed with ILD on HRCT were enrolled...

BACKGROUND: In the regular wildlife monitoring action carried out in the summer of the past few years at the Berlenga Island, wild rabbits (Oryctolagus cuniculus) have been repeatedly found dead. However, the origin of those deaths was never investigated. Our aim was to investigate the cause of death of 11 rabbits collected between April and May 2016. RESULTS: While screening samples from rabbit carcasses for the major viral rabbit pathogens, five tested positive to RHDV2 but all were negative for RHDV and myxoma virus (MYXV)...

OBJECTIVE: A substantial proportion of cases of usual interstitial pneumonia (UIP) are due to connective tissue disease (CTD)-associated interstitial lung disease (ILD). The purpose of this study was to determine whether specific CT findings can help differentiate a UIP pattern of CTD-ILD from a UIP pattern of idiopathic pulmonary fibrosis (IPF) and whether these signs are associated with survival. MATERIALS AND METHODS: Adults visiting an ILD clinic from 2006 to 2015 enrolled in a research registry with a multidisciplinary diagnosis of CTD-ILD or IPF and a UIP pattern at high-resolution CT were included in the study...

BACKGROUND AND OBJECTIVE: Usual gait speed over 4 m (4MGS) is an established functional performance measure in older adults that consistently predicts adverse health outcomes, but few data exist in idiopathic pulmonary fibrosis (IPF). We assessed the reliability of 4MGS, its relationship with established outcome measures and its responsiveness to pulmonary rehabilitation. METHODS: In four prospective IPF cohorts, 4MGS inter-observer (n = 46) and test-retest (n = 46) reliability, concurrent validity (n = 65 and n = 62) and responsiveness (n = 60) were determined...

Pulmonary fibrosis is a chronic, progressive, lethal lung disease characterized by alveolar cell necrosis and dysplasia of interstitial fibrotic tissue, resulting in loss of lung function and eventual respiratory failure. Previously, glucocorticoid drugs were used to treat this lung disorder. However, positive responses were recorded in less than half of treated patients and the cytotoxicity caused by high dosage treatment is still a concern. The present study investigated whether ulinastatin, a typical urinary trypsin inhibitor that mitigates numerous inflammatory responses, could be a treatment option for lung fibrosis...

So Hyeon Bak, Ho Yun Lee
Smoking-related interstitial lung disease (ILD) consists of a heterogeneous group of disorders that are considered a distinct entity. The 2013 American Thoracic Society and European Respiratory Society recommendations classified respiratory bronchiolitis (RB)/RB-ILD and desquamative interstitial pneumonia (DIP) as smoking-related idiopathic interstitial pneumonias (IIPs). The overlapping histopathological and radiological patterns of smoking-related IIPs must be considered. Overlap patterns of smoking-related IIPs are not easily classified as a single disorder...

Clinical diagnosis of lymphomatoid granulomatosis (LYG) often is difficult, especially in patients with multiple comorbidities. We present a 60-year-old woman with worsening fatigue, night sweats, unintentional weight loss, and dyspnea of 2 weeks' duration. Her medical history was remarkable for recent radiation therapy for recurrent breast cancer and antisynthetase syndrome complicated by interstitial lung disease and controlled with azathioprine. Computed tomography showed ground-glass opacities and nodular infiltrates in all lung lobes, raising concern for radiation pneumonitis and drug toxicity...
