BACKGROUND Respiratory viral infections lead to bronchial inflammation in patients with cystic fibrosis, especially during pulmonary exacerbations. The aim of this study was to determine the impact of viral-associated pulmonary exacerbations in children with cystic fibrosis and failure to improve forced expiratory volume in 1 s (FEV1 ) after an appropriate treatment. METHODS We lead a pilot s...

Pulmonary fibrosis is a respiratory disease with a high mortality rate and its pathogenesis involves multiple mechanisms including epithelial cell injury, fibroblast proliferation, inflammation, and collagen coagulation. The treatment regimens still fail to recover this disease. We have previously found that dihydroartemisinin inhibits the development of pulmonary fibrosis in rats. This study a...

Cystic fibrosis affects multiple organs but lung disease remains the major determinant of patient morbidity and mortality. Cystic fibrosis lung disease is characterized by chronic infection and inflammation. The amino acid L-arginine is substrate for both nitric oxide synthases and arginases. The activity of arginase in sputum is increased while the production of nitric oxide is reduced in the ...

this paper presents four cases of abnormal soft tissue activity in the bone scan of patients with different lesions (lung inflammatory pseudotumor, pulmonary fibrosis, pulmonary metastatic osteosarcoma and metastatic hepatic carcinoma of colon).

BACKGROUND The outcome of patients suffering from pulmonary arterial hypertension (PAH) are predominantly determined by the response of the right ventricle to the increase afterload secondary to high vascular pulmonary resistance. However, little is known about the effects of the current available or experimental PAH treatments on the heart. Recently, inflammation has been implicated in the pat...

Chronic inflammation and proinflammatory cytokines as well as T helper type 2 (Th2) cytokines have been involved in the pathogenesis of pulmonary injury and lung fibrosis. The actual role of IL-10 in lung fibrosis is still unclear because this cytokine has been identified as Th2 but possesses strong anti-inflammatory properties. To better dissect the potential role of IL-10 in silica-induced lu...

Introduction: Pulmonary involvement secondary to Systemic Sclerosis (SSc) is the major cause of morbidity and mortality in SSc patients. We designed this study to determine the correlation of important lung function parameters with lung High Resolution CT (HRCT) scan findings. Materials and Methods: Thirty–two consecutive diffuse SSc patients with pulmonary fibrosis were enrolled in this cross...
