Background: Portopulmonary hypertension (PoPH) is a rare condition associated with poor survival, and the effect of modern therapies that target pulmonary arterial hypertension (PAH) on long-term outcome is unknown. This study investigated the baseline characteristics and survival in the cohort of patients diagnosed with PoPH in the United Kingdom National Pulmonary Hypertension Service. Methods: A retrospective review was conducted of all incident treatment-naïve patients with PoPH within the United Kingdom national registry diagnosed between January 2001 and December 2010. Results: Patients with PoPH (n = 110) had survival rates of 85%, 60%, and 35% at 1, 3, and 5 years. The prevalence of PoPH was 0.85 cases/1 million. Mean age at diagnosis was 53 ± 12 years, with a balanced distribution in gender. Alcohol (n = 57) and hepatitis C (n = 10) were the most common causes of portal hypertension. Phosphodiesterase V inhibitors were the most frequently used targeted therapy, in 63.6% (n = 70) of patients, endothelin receptor antagonists were used in 10% (n = 11) and prostacyclin analogs in 12.7% (n = 14). Univariate and multivariate analysis of baseline characteristics did not demonstrate a significant influence of severity of portal hypertension or liver cirrhosis, World Health Organization Functional Class, cardiopulmonary hemodynamics, or year of diagnosis on survival. Conclusions: Survival of patients with PoPH remains poor despite targeted therapy and worse than patients with idiopathic PAH. The benefit of PAH therapies in PoPH on long-term morbidity and mortality outcomes needs further consideration and study.
