Airway stent implantation can improve the symptoms of airway stenosis caused by a malignant tumor immediately. However, stent implantation is only a palliative therapy and disease will quickly progress without subsequent treatment. Targeted therapy can provide accurate etiological treatment for patients with critical lung cancer who cannot receive chemotherapies. In our clinic, we encountered a 50-year-old male presenting with stage IV lung adenocarcinoma. He failed both the first-line and second-line chemotherapies and suffered severe complex left and right main bronchial stenoses caused by tumor invasion...

Plastic bronchitis is used to designate endobronchial plugs of rubber-like consistency that form into bronchial trees. It has been described in several diseases like asthma, cystic fibrosis, pulmonary infection, cyanotic congenital heart disease and in few young children with homozygous sickle cell disease. We report the first sickle cell adult case of plastic bronchitis during acute chest syndrome. He developed severe acute respiratory distress syndrome. This unusual presentation related to obstruction by voluminous casts may alert physicians to focus more on the bronchi in sickle cell patients...

A 7 week old infant was admitted with respiratory failure. Chest X-ray showed an atelectatic right upper lobe, herniation of right middle and lower lobe into the left thorax, and compression-atelectasis of the left lung. Thoracic CT showed complete occlusion of the right superior bronchus with a radiopaque foreign material. Six weeks prior, an impression for a palate plate using polyvinylsiloxane was taken. The material was removed with a rigid endoscopy, in readiness of extracorporeal oxygenation in case of tracheal obstruction or bronchial rupture...

Asthma is a chronic heterogeneous illness of the lower airway with an inflammatory basis, developing from hyperresponsiveness and bronchial obstruction. One of the more unfavourable processes occurring in the airway are the long-term changes of the respiratory tract known as remodelling, resulting in complete irreversible obstruction. Bone morphogenetic protein (BMP) is a member of the Transforming Growth Factor beta (TGF-b) superfamily, which regulates processes in embryonic and post-embryonic development...

BACKGROUND: Bronchial artery aneurysm (BAA) is a rare condition with a reported prevalence of less than 1% of all selective bronchial arterial angiograms. Despite its low incidence, BAA represents a potential cause of hemoptysis. CASE REPORT: We describe the case of a 63-year-old man suffering from chronic obstructive pulmonary disease (COPD), who presented with non-massive hemoptysis. CT angiography revealed a single bronchial artery aneurysm of 9 mm in diameter, abutting the esophageal wall...

Clinical experience has shown that allergic and non-allergic respiratory, metabolic, mental, and cardiovascular disorders sometimes coexist with bronchial asthma. However, no study has been carried out that calculates the chance of manifestation of these disorders with bronchial asthma in Saarland and Rhineland-Palatinate, Germany. Using ICD10 diagnoses from health care institutions, the present study systematically analyzed the co-prevalence and odds ratios of comorbidities in the asthma population in Germany...

BACKGROUND: Cell therapy holds the most promising for acute and chronic deleterious respiratory diseases. However, the safety and tolerance for lung disorders are controversy. METHODS: We undertook a systematic review and meta-analyses of all 23 clinical studies of cell therapy. The outcomes were odds ratio (OR), risk difference (RD), Peto OR, relative risk, and mean difference of serious adverse events. RESULTS: 342 systemic infusions and 57 bronchial instillations (204 recipients) of cells were analyzed for acute respiratory distress syndrome (ARDS), bronchopulmonary dysplasia, pulmonary arterial hypertension, silicosis, sarcoidosis, extensively drug-resistant tuberculosis, chronic obstructive pulmonary diseases (COPD), and idiopathic pulmonary fibrosis...

Duchenne muscle dystrophy (DMD), X-linked recessive genetic disorder, causes a variety of complications including scoliosis. We report a case of bronchial obstruction and hemorrhage caused by scoliosis with DMD. A man in his forties having been hospitalized due to DMD since the age of 6, produced bloody sputum. A chest X-ray showed atelectasis in his right lower lung. A computed tomography and bronchoscopy indicated that scoliosis and thoracic deformity due to muscle dystrophy caused compression of a right main bronchus by the vertebra, leading to bronchial obstruction and bleeding...

Adenosine induces bronchial hyperresponsiveness and inflammation in asthmatics through activation of A2B adenosine receptor (A2BAdoR). Selective antagonists have been shown to attenuate airway reactivity and improve inflammatory conditions in pre-clinical studies. Hence, the identification of novel, potent and selective A2BAdoR antagonist may be beneficial for the potential treatment of asthma and Chronic Obstructive Pulmonary Disease (COPD). Towards this effort, we explored several prop-2-ynylated C8-aryl or heteroaryl substitutions on xanthine chemotype and found that 1-prop-2-ynyl-1H-pyrazol-4-yl moiety was better tolerated at the C8 position...

Tracheobroncopathia osteochondroplastica (TO) is a benign disease of the large airways seen very rarely. It is characterized by 1-3 mm sized ossified nodular lesions in submucosa. Its etiology is unclear, but it is stated that malignancy, chronic inflammation, amyloidosis, and genetic factors might have an effect on it. It was first described by Wilks in a 38-year-old man diagnosed with tuberculosis in 1857. Generally, patients are asymptomatic and TO is diagnosed incidentally. But symptoms become significant with infections and obstruction in tracheabronchial tree...

Pulmonary carcinoids are rare low-grade malignant tumors, which arise from the neuroendocrine system. Approximately 80% of all pulmonary carcinoid tumors are the relatively low-grade typical carcinoids and 20% are the more aggressive atypical carcinoids. Most carcinoids arise from the central airways and only a minority of carcinoids are found in the lung periphery. While most of the peripheral carcinoids are asymptomatic, central carcinoids are symptomatic and present with hemoptysis, wheezing or bronchial obstruction...

Influenza A virus (IAV) infections lead to severe inflammation in the airways. Patients with chronic obstructive pulmonary disease (COPD) characteristically have exaggerated airway inflammation and are more susceptible to infections with severe symptoms and increased mortality. The mechanisms that control inflammation during IAV infection and the mechanisms of immune dysregulation in COPD are unclear. We found that IAV infections lead to increased inflammatory and antiviral responses in primary bronchial epithelial cells (pBECs) from healthy nonsmoking and smoking subjects...

PURPOSE: Chronic kidney disease (CKD) is an emerging issue in patients with chronic obstructive pulmonary disease (COPD). In COPD, loss of muscle mass is relatively common finding, and diagnosis of CKD should be based on measured or estimated GFR (Cavailles et al. Eur Respir Rev 22:454-475, 2013; Gosker et al. Am J Clin Nutr 71:1033-1047, 2000; Delanaye and Mariat Nat Rev Nephrol 9:513-522, 2013). We aimed to determine the prevalence and impact of CKD, defined by using chronic kidney disease epidemiology collaboration (CKD-EPI) equation, in COPD patients...

Airway remodelling is an important component of chronic obstructive pulmonary disease (COPD). Neutrophil gelatinase-associated lipocalin (NGAL) from neutrophils may drive COPD epithelial-mesenchymal transition (EMT). NGAL expression was quantified in the lungs of COPD patients and bronchoalveolar lavage fluid (BALF) of ozone-treated mice. Reticular basement membrane (RBM) thickness and E-cadherin and α-smooth muscle actin (α-SMA) expression were determined in mice airways. Effects of cigarette smoke extract (CSE) and inflammatory factors on NGAL expression in human neutrophils as well as the effects of NGAL on airway structural cells was assessed...
