Abstract

Data on treatment of patients with portopulmonary hypertension (PoPH) are limite as they are usually excluded from randomised controlled trials with pulmonary arterial hypertension (PAH)-specific therapies. This study investigated the short- and long-termefficacy/safety of bosentan in these patients, as well as its pharmacokinetics.

All 34 consecutive patients with PoPH treated with first-line bosentan (December 2002 to July 2009) were retrospectively evaluated. Assessments included the New York Heart Association functional class (NYHA FC), blood tests, haemodynamics, 6-min walk distance (6MWD) and eventfree status. The pharmacokinetics of bosentan in five patients with Child–Pugh (C-P) class B cirrhosis were compared with idiopathic PAH patients.

Significant improvements from baseline were observed in NYHA FC, 6MWD and haemodynamics, and were largely maintained during follow-up. Patients with C-P class B cirrhosis (n59) had significantly larger haemodynamic improvement after mean¡SD 5¡2 months. Mean followup time was 43¡19 months; four patients died and seven patients had significant elevation of liver enzymes (annual rate 5.5%). Plasma concentrations of bosentan were higher in patients with C-P class B cirrhosis than those observed in idiopathic PAH.

These data confirm the benefit of bosentan treatment for patients with PoPH. Haemodynamic improvements were particularly pronounced in patients with more severe cirrhosis. The safety profile of bosentan was consistent with previous studies.
