BACKGROUND: Chronic obstructive pulmonary disease (COPD) is a heterogeneous disorder encompassing different phenotypes with different responses to treatment. The present 1-year, two-center hospital-based study investigated whether the plasma immunoglobulin E (IgE) level and/or eosinophil cell count could be used as biomarkers to stratify patients with COPD according to predicted responses to inhaled corticosteroids (ICS)-based therapy. METHODS: A hospital-data based cohort study of COPD patients treated at two territory hospital centers was conducted for 1 year...

Bovine herpesvirus 1 (BoHV-1), an important bovine pathogen, establishes life-long latency in sensory neurons. Latently infected calves consistently reactivate from latency following a single intravenous injection of the synthetic corticosteroid dexamethasone. The immediate early transcription unit 1 (IEtu1) promoter, which drives bICP0 and bICP4 expression, is stimulated by dexamethasone because it contains two glucocorticoid receptor (GR) response elements (GREs). Several Krüppel-like transcription factors (KLF), including KLF15, are induced during reactivation from latency and they stimulate certain viral promoters and productive infection...

Immunosuppressive therapy is a known risk factor for opportunistic infections. We report the first case of severe Pneumocystis jirovecii infection requiring intensive care in a pediatric patient with inflammatory bowel disease (IBD). The literature was reviewed and there were 92 reported cases of Pneumocystis pneumonia (PCP) in patients with IBD. Most sources were case reports and there was likely reporting bias toward patients receiving immunomodulators, anti-tumor necrosis factor (anti-TNF) therapy, and those who died...

Idiopathic pneumonia syndrome (IPS) is a complication of allogeneic hematopoietic stem cell transplantation (HSCT) that typically occurs within the first 100 days after transplantation. Tumor necrosis alpha-α (TNF-α) has been shown to be a key mediator of IPS, and the TNF-α binding protein, etanercept, appears to improve IPS outcomes in small retrospective and prospective studies. IPS has also been observed to occur later (>100 days) after HSCT; however, little is known about the disease course and whether a TNF-α-based therapeutic strategy is efficacious in these patients...

To study the clinical characteristics of autoimmune rheumatic disease-related organizing pneumonia (AIRD-OP), the clinical presentation, radiological findings, treatment, and outcome of AIRD-OP patients were analyzed, in comparison with patients with cryptogenic organizing pneumonia (COP). A total of 131 OP patients were identified, including 57 cases of AIRD-OP, 35 cases of COP, and 39 cases of other disease-related OPs. Among AIRD-OP patients, 36 (63%) presented the symptoms of OP at onset. The primary disease of AIRDs included Sjogren's syndrome (38%), polymyositis/dermatomyositis (23%), rheumatoid arthritis (23%), and undifferentiated AIRD...

Organizing pneumonia (OP) is an inflammatory lung disease characterized pathologically by the presence of buds of granulation tissue in the distal air spaces. There are numerous causes of OP including acute respiratory infections such as viral and bacterial infections. However, Mycobacterium abscessus (M. abscessus) has rarely been reported as a causative pathogen of OP. Here, we report a 67-year-old woman with rapidly progressive pulmonary M. abscessus infection who developed OP and acute respiratory failure (ARF)...

BACKGROUND: Adult onset Still disease (AOSD) is a rare condition characterized by elevated fever along with arthritic symptoms, elevated polymorphonuclear neutrophil count, evanescent rash, and hyperferritinemia. Diagnosis can be made only after have ruled out more frequent conditions, and Yamagouchi or Fautrel criteria should be applied. Parenchimal lung involvement (PLI) is present in less than 5% of AOSD cases and ranges from aspecific reticular interstitial opacities to life threatening conditions, such as acute respiratory distress syndrome (ARDS)...

Recent studies have suggested that inhaled corticosteroids (ICS) may be associated with higher risks of tuberculosis and pneumonia in patients with COPD. However, it is not known whether ICS increases the risk of upper respiratory tract infection (URTI). Aim of this study was to explore the relationship between ICS and URTI. Through a comprehensive literature search of PubMed, EMBASE, Cochrane Library, and Google Scholar from inception to March 2016, we identified randomized controlled trials of ICS therapy lasting at least 6 months...

Eosinophilic pneumonia is characterized by pulmonary eosinophilia associated with and/or alveolar eosinophilia. Furthermore, blood eosinophilia may be absent particularly in patients who have benefited beforehand of corticosteroids. The most common causes are parasites and drugs. According to the classification, we distinguish idiopathic pneumonia with eosinophils, those related to vasculitis and those of known etiology. Extrapulmonary involvement is frequently found in the subgroup of vasculitis. It is important to diagnose and start treatment quickly to reduce the risk of complications...

Long-term maintenance therapy for COPD is evolving rapidly. Dual bronchodilation with new long-acting muscarinic antagonist and long-acting beta-agonist (LAMA/LABA) fixed dose combination inhalers were introduced over the past 2 years. In clinical trials, these inhalers significantly improved lung function (trough forced expiratory volume in 1 second), patient-reported outcomes, and quality of life measures compared with placebo, their respective monocomponents, and tiotropium. The recorded adverse events of these new inhalers were also similar to those of their monocomponents or placebo...

Community acquired pneumonia remains a common cause of morbidity and mortality. Usually, the causal organism is not identified and treatment remains empiric. Recent computed tomography and magnetic resonance imaging studies have challenged the accuracy of the clinical diagnosis of pneumonia, and epidemiologic studies are changing our perspective of what causes community acquired pneumonia, especially the role of viral pathogens and the frequent finding of multiple pathogens. The past decade has seen increasing overuse of empiric coverage of meticillin resistant Staphylococcus aureus and antibiotic resistant Gram negative pathogens owing to inappropriate application of guidelines for healthcare associated pneumonia...

Sepsis is a life-threatening health condition caused by infectious pathogens of the respiratory tract, and accounts for 28-50% of annual deaths in the US alone. Current treatment regimen advocates the use of corticosteroids as adjunct treatment with antibiotics, for their broad inhibitory effect on the activity and production of pro-inflammatory mediators. However, despite their use, corticosteroids have not proven to be able to reverse the death incidence among septic patients. We have previously demonstrated the potential for neuroendocrine factors to directly influence Streptococcus pneumoniae virulence, which may in turn mediate disease outcome leading to sepsis and septic shock...

Mycoplasma pneumoniae pneumonia (MPP) is one of the most common forms of community-acquired pneumonia in children and adolescents. Outbreaks of MPP occur in 3- to 7-year cycles worldwide; recent epidemics in Korea occurred in 2006-2007, 2011, and 2015-2016. Although MPP is known to be a mild, self-limiting disease with a good response to macrolides, it can also progress into a severe and fulminant disease. Notably, since 2000, the prevalence of macrolide-resistant MPP has rapidly increased, especially in Asian countries, recently reaching up to 80%-90%...

Oral direct-acting antivirals (DAAs) are the main therapy for hepatitis C virus (HCV)-associated liver disease in Japan. Daclatasvir/asunaprevir is the first agent and sofosbuvir/ledipasvir is the secondary agent for HCV genotype 1b. More recently, ombitasvir/paritaprevir/ritonavir is also recommended as a potent therapy for HCV genotype 1b. Among the adverse events associated with these oral DAAs, interstitial pneumonia is one of the most severe ones. Regarding treatment with daclatasvir plus asunaprevir or sofosbuvir plus ledipasvir, a few cases have already been reported in a postmarketing surveillance...
