Current Practice of Airway Stenting in the Adult Population in Europe: A Survey of the European Association of Bronchology and Interventional Pulmonology (EABIP).

Background: Airway stenting (AS) commenced in Europe circa 1987 with the first placement of a dedicated silicone airway stent. Subsequently, over the last 3 decades, AS was spread throughout Europe, using different insertion techniques and different types of stents.

Objectives: This study is an international survey conducted by the European Association of Bronchology and Interventional Pulmonology (EABIP) focusing on AS practice within 26 European countries.

Mucin5B expression by lung alveolar macrophages is increased in long-term smokers.

This study investigated the expression of MUC5B by AMs in the lungs of cigarette smokers and nonsmokers. We analyzed MUC5B expression by measuring the levels of apomucin and mRNA in human BALF cells from 50 subjects (20 nonsmokers, 17 patients with CB, and 13 patients with COPD). apoMUC5B was observed in BALF mononuclear cells in 60% of all subjects, but a significantly higher frequency of apoMUC5B(+) cells was found in subjects with CB (95% CI, 4.

Regular albuterol or nedocromil sodium--effects on airway subepithelial tenascin in asthma.

Both albuterol and nedocromil sodium have been recognized to possess certain anti-inflammatory properties. However, there are no data on the impact of these drugs on the pathophysiology of the bronchial extracellular matrix in asthma characterized by enhanced tenascin (Tn) expression, known to occur proportional to the severity of asthma. This paper reports data from a morphometric study on the effects of regular treatment with inhaled albuterol or nedocromil sodium on the extent of bronchial subepithelial deposition of Tn, collagen types III, IV, and VII and mucosal infiltration with macrophages.

Effect of regular nedocromil sodium or albuterol on bronchial inflammation in chronic asthma.

Nedocromil sodium is recommended for daily treatment of mild persistent asthma but its effect on cellular changes in asthmatic airways is poorly understood. We compared the antiinflammatory effects of nedocromil sodium and albuterol in 32 patients with asthma who received either nedocromil sodium 4 mg or albuterol 0.2 mg four times daily for 12 weeks according to a double-blind protocol.
