OBJECTIVE To compare the effectiveness of discontinuing treatment with amoxicillin after three days or eight days in adults admitted to hospital with mild to moderate-severe community acquired pneumonia who substantially improved after an initial three days' treatment. DESIGN Randomised, double blind, placebo controlled non-inferiority trial. SETTING(More)
BACKGROUND Chronic thromboembolic pulmonary hypertension (CTEPH) is often a sequel of venous thromboembolism with fatal natural history; however, many cases can be cured by pulmonary endarterectomy. The clinical characteristics and current management of patients enrolled in an international CTEPH registry was investigated. METHODS AND RESULTS The(More)
RATIONALE Salmeterol is a beta2-adrenoreceptor agonist used in the treatment of obstructive pulmonary disease. Salmeterol inhibits inflammatory responses by neutrophils and mononuclear cells in vitro and in mouse models of lung inflammation in vivo. OBJECTIVE To determine the effect of salmeterol on LPS-induced lung inflammation in humans. METHODS(More)
Urokinase-type plasminogen activator (uPA) and its receptor uPAR are components of the fibrinolytic system and are important for an adequate immune response to respiratory tract infection, in part through their role in the migration of inflammatory cells. PA inhibitor-1 (PAI-1) is the predominant inhibitor of soluble and receptor-bound uPA. To determine the(More)
Pathophysiological findings in chronic thromboembolic pulmonary hypertension (CTEPH) have suggested that a secondary small vessel arteriopathy may contribute to the haemodynamic impairment observed in these patients. It was hypothesised that this element of the elevated vascular resistance may be responsive to continuous intravenous epoprostenol therapy.(More)
Severe infection is associated with profound alterations in the systemic haemostatic balance, with activation of coagulation and suppressed fibrinolysis. Within the alveolar compartment, similar disturbances have been described during pulmonary inflammation. The current authors investigated whether local haemostasis was influenced during(More)
Toll-like receptors (TLRs) are pattern-recognition receptors that have been implicated in the initiation of innate immune responses upon the first encounter with invading pathogens. The airways are frequently exposed to various types of lipopolysaccharide (LPS) from the environment or from pathogens. The current study was designed to determine the effect of(More)
Pulmonary endarterectomy (PEA) is recommended as the treatment of choice for eligible patients with chronic thromboembolic pulmonary hypertension (CTEPH). However, only a proportion of patients fulfill the criteria for surgical intervention. In addition, operated patients with CTEPH may experience a gradual hemodynamic and symptomatic decline related to a(More)
Pulmonary arterial hypertension associated with congenital heart disease caused by systemic-to-pulmonary shunting was associated with a high risk of morbidity and mortality. In this retrospective study, the longer term treatment effect of bosentan on exercise capacity and quality of life (QoL) were evaluated in 58 adult patients (>18 years) with pulmonary(More)
BACKGROUND A study was undertaken to determine whether a short course of antibiotic treatment (< or = 5 days) is as effective as the conventional longer treatment in acute exacerbations of chronic bronchitis and chronic obstructive pulmonary disease (COPD). METHODS MEDLINE, EMBASE and the Cochrane central register of controlled trials were searched to(More)
