title: The importance of predicting the prognosis in patients with hepatopulmonary syndrome: a simple scoring system.
abstract: Hepatopulmonary syndrome (HPS) is a pulmonary vascular disorder, complicating hepatic diseases, and is responsible for an increased morbidity and mortality among patients awaiting liver transplantation. Nowadays, it is recognized as an independent risk factor for death in this patient population. The severity of hypoxemia and the advanced stage of the liver dysfunction are determinants for the prognosis. Therefore, the possibility to be successful, thus improving survival, consists of addressing HPS at an earlier stage, giving more attention to moderate evidences of this pathology instead of the severe ones. On the basis of scientific evidence, we suggest a simple scoring system to predict prognosis among patients with HPS, founded on the integration of two main factors: the severity of hepatic disease, expressed as class of Child-Pugh, and the severity of the hypoxemia. This model of prognostic evaluation has the objective of estimating the additional risk of these patients, thereby avoiding a deleterious underestimate of risk and an arbitrariness of management.
