Upregulation of basic fibroblast growth factor in smokers with chronic bronchitis
The aim of the study was to investigate the expression of basic fibroblast growth factor (bFGF) and its receptor, fibroblast growth factor receptor (FGFR)-1, in the central airways of smokers with chronic bronchitis. The lobar bronchi from 17 subjects undergoing thoracotomy for solitary nodules were examined. All had a history of cigarette smoking, nine had symptoms of chronic bronchitis and airflow limitation, and eight were asymptomatic with normal lung function. Using immunohistochemical methods, bFGF and FGFR-1 expression in the total airway wall and the different airway compartments, i.e. bronchial glands, submucosal vessels and smooth muscle, was quantified. Moreover, to investigate t…
Rapidly progressive organising pneumonia associated with cytomegalovirus infection in a patient with psoriasis.
A 63-year-old woman experienced progressive respiratory distress and psoriatic plaques. The radiographic images showed diffuse interstitial infiltrates. The surgical open lung biopsy revealed an obliteration of the alveolar spaces by plugs of connective tissue distributed within the terminal bronchioles, alveolar ducts and spaces. No relevant cause was determined, and she was diagnosed with idiopathic organising pneumonia. The patient was discharged with oral glucocorticosteroid and supplemental oxygen therapy. One month later, the patient’s pulmonary status had progressively worsened, and she was re-admitted. She required higher oxygen concentrations and mechanical ventilation. Pharmacol…
