Inclusion Criteria:
Patients must:
- Had portal hypertension.
- Be otherwise suitable candidates for OLT.
- Had severe pulmonary arterial hypertension (PAH) defined as a resting mean pulmonary arterial pressure (mPAP) >35 mmHg and pulmonary vascular resistance (PVR) ≥3 Wood Units (WU) by right heart catheterization (RHC) performed as part of standard of care evaluation within 90 days of enrollment.
- Treprostinil therapy must be recommended by the treating physician per standard of care.
- Be NYHA Functional Class II, III, or IV.
- Had pulmonary capillary wedge (PCW) pressure ≤18 mmHg and transpulmonary gradient (TPG) ≥15 mmHg.
Exclusion Criteria:
Patients must not:
- Had received any any investigational therapy as part of a clinical trial for any indication within 30 days prior to enrollment.
- Had a change in dose of treatment for PAH (bosentan [Tracleer], ambrisentan [Letairis], tadalafil [Adcirca], or sildenafil [Revatio]), within 30 days prior to enrollment. That is, subjects may have been treated with any of these agents provided the dose was stable for at least 30 days prior to enrollment.
- Had renal failure requiring hemodialysis.

Portopulmonary hypertension
|
Remodulin is supplied in concentrations of 1, 2.5 , 5, and 10 mg/mL and can be administered as supplied or diluted for intravenous (IV) infusion prior to administration. Remodulin is indicated for subcutaneous (SC) or IV use only as a continuous infusion. Remodulin is preferably infused subcutaneously, but can be administered by a central IV line if the SC route is not tolerated. The infusion rate is initiated at 1.25 ng/kg/min. If this initial dose cannot be tolerated because of systemic effects, the infusion rate should be reduced to 0.625 ng/kg/min.

Change in Quality of Life From Baseline to Weeks 12 and 24
Aikaikkuna: Baseline and Weeks 12 and 24
|
The 36-item Short Form Survey (SF-36) is a health related quality of life instrument, which measures dimensions of physical and social roles and functioning, mental health, vitality, and pain.
Items are scored on a 0 to 100 range so that the lowest scores represent the highest disability.
The quality of life assessment was conducted at Baseline and Weeks 12 and 24 and the change from Baseline to Weeks 12 and 24 is presented.
