Hepatopulmonary syndrome (HPS) is characterized by pulmonary vasodilation and subsequent hypoxemia in the setting of hepatic dysfunction. There is currently no pharmacologic intervention that has been shown to significantly affect outcomes and liver transplantation remains the mainstay of therapy. Unfortunately, patients undergoing liver transplantation are at high risk of significant hypoxemia...

BACKGROUND Hepatopulmonary syndrome (HPS) is a complication of advanced liver disease. The impact of HPS on survival is not clearly understood. MATERIAL AND METHODS A prospective study was carried out at Department of Medicine, King Edward Medical University Lahore from June 2011 to May 2012. Patients with cirrhosis of liver were evaluated for presence of HPS with arterial blood gas analysis ...

BACKGROUND Hepatopulmonary syndrome (HPS) is a relatively common complication in patients with decompensated cirrhosis. Our aim was to evaluate the prevalence of HPS, its clinical impact, and the possible association between HPS and characteristics of patients with decompensated cirrhosis. METHODS Patients with stable decompensated cirrhosis admitted to our department and assessed for HPS wer...

AIM Hepatopulmonary syndrome is a pulmonary dysfunction in the context of liver cirrhosis characterized by arterial deoxygenation. Affected patients have increased morbidity and mortality, and many of them expire before undergoing liver transplantation. Therefore, finding medical therapy as a bridge to transplantation or as a final treatment is necessary. In this study, we aimed to review the c...

Hepatopulmonary syndrome (HPS) is characterized by a triad of severe liver disease, intrapulmonary vascular dilation and hypoxaemia. Pulmonary vascular remodelling (PVR) is a key feature of HPS pathology. Our previous studies have established the role of the pulmonary artery smooth muscle cell (PASMC) phenotypic modulation and proliferation in HPS-associated PVR. Myocardin, a robust transcripti...

Experimental hepatopulmonary syndrome (HPS) after common bile duct ligation (CBDL) in rat is accompanied by increased lung vascular endothelial endothelin B (ETB) receptor expression and increased circulating levels of endothelin-1 (ET-1). The onset of HPS is hypothesized to be triggered by ET-1/ETB receptor activation of endothelial nitric oxide synthase (eNOS)-derived NO production in the pul...

Hepatopulmonary syndrome (HPS) is one of the reasons for the mortality of patients with perioperative liver disease. Intrapulmonary vascular dilatation is the most important mechanism underlying HPS, and it primarily occurs due to cell proliferation. Inhibiting the proliferation of pulmonary microvascular endothelial cells (PMVECs) may provide a novel strategy to prevent HPS. MicroRNAs (miRNAs)...

BACKGROUND Hepatopulmonary syndrome (HPS) is a rare complication of liver diseases of different etiologies and may indicate a poor prognosis. Therefore, a simple non-invasive screening method to detect HPS would be highly desirable. In this study pulse oximetry was evaluated to identify patients with HPS. METHODS In 316 consecutive patients with liver cirrhosis (n = 245), chronic hepatitis (n...

Hepatopulmonary syndrome (HPS) is the one of the complication of liver cirrhosis with portal hypertension, irrespective of etiology, age and sex. It has also been observed in non cirrhotic portal hypertension and in acute hepatic conditions. Presence of hypoxemia or abnormal alveolar arterial oxygen tension with intrapulmonary vasodilation in liver cirrhosis is termed as HPS. Contrast echocardi...

BACKGROUND Hepatopulmonary syndrome (HPS) is defined as an oxygenation defect induced by intrapulmonary vasodilation in patients with liver disease or portal hypertension. It is investigated in patients with liver cirrhosis and less frequently in those with portal hypertension without liver cirrhosis, as may occur in hepatosplenic schistosomiasis (HSS). OBJECTIVES To investigate the prevalenc...
