The dual endothelin receptor antagonist bosentan has been approved in several countries for pulmonary arterial hypertension, and patients with portopulmonary hypertension (PPHTN) have not specifically been excluded. However, no data have been published on the efficacy and safety of bosentan in this patient population. Here, the first clinical experiences(More)
Combination therapy may improve outcome in patients with severe pulmonary arterial hypertension (PAH). PAH patients were treated according to a goal-oriented therapeutic strategy. Patients who did not reach the treatment goals with monotherapy received combination treatment according to a predefined strategy, including bosentan, sildenafil and inhaled(More)
It has been proposed that targeted treatments should be combined for patients with idiopathic pulmonary arterial hypertension (IPAH) responding insufficiently to monotherapy. This study followed the clinical course of nine patients with severe IPAH, in whom the endothelin receptor antagonist bosentan caused transient clinical improvement, eventually(More)
Obliterative bronchiolitis is commonly interpreted as chronic rejection and involves the bronchial and bronchiolar epithelium. Upregulation of major histocompatibility complex (MHC) II on bronchial epithelial cells (BEC) had been hypothesised to be an important trigger of a bronchus directed rejection response.

OBJECTIVE Tacrolimus has been shown to provide superior immunosuppression in various solid organ transplant settings. The purpose of our study was to compare the survival of porcine lung allografts after induction with either cyclosporine A (CsA) or tacrolimus. METHODS Single lung transplantation from MHC mismatched donors was performed in 10 minipigs.(More)
