Effects of Albumin Treatment on Systemic and Portal Hemodynamics and Systemic Inflammation in Patients With Decompensated Cirrhosis.

Background & Aims: We investigated the effect of albumin treatment (20% solution) on hypoalbuminemia, cardiocirculatory dysfunction, portal hypertension, and systemic inflammation in patients with decompensated cirrhosis with and without bacterial infections.

Methods: We performed a prospective study to assess the effects of long-term (12 weeks) treatment with low doses (1 g/kg body weight every 2 weeks) and high doses (1.5 g/kg every week) of albumin on serum albumin, plasma renin, cardiocirculatory function, portal pressure, and plasma levels of cytokines, collecting data from 18 patients without bacterial infections (the Pilot-PRECIOSA study).

Sorafenib or placebo plus TACE with doxorubicin-eluting beads for intermediate stage HCC: The SPACE trial.

Background & Aims: Transarterial chemoembolization with doxorubicin-eluting beads (DC Bead®; DEB-TACE) is effective in patients with Barcelona clinic liver cancer stage B hepatocellular carcinoma (HCC). The multikinase inhibitor sorafenib enhances overall survival (OS) and time-to-tumor progression (TTP) in patients with advanced HCC. This exploratory phase II trial tested the efficacy and safety of DEB-TACE plus sorafenib in patients with intermediate stage HCC.

Cirrhotic cardiomyopathy.

During the course of cirrhosis, there is a progressive deterioration of cardiac function manifested by the disappearance of the hyperdynamic circulation due to a failure in heart function with decreased cardiac output. This is due to a deterioration in inotropic and chronotropic function which takes place in parallel with a diastolic dysfunction and cardiac hypertrophy in the absence of other known cardiac disease. Other findings of this specific cardiomyopathy include impaired contractile responsiveness to stress stimuli and electrophysiological abnormalities with prolonged QT interval.

Diastolic dysfunction is a predictor of poor outcomes in patients with cirrhosis, portal hypertension, and a normal creatinine.

Unlabelled: We investigated left ventricular diastolic dysfunction (LVDD) and its relationship with circulatory function and prognosis in cirrhosis with portal hypertension and normal creatinine. Conventional and tissue Doppler (TDI) echocardiography, systemic and hepatic hemodynamics, and the activity of endogenous vasoactive systems (AEVS) were measured prospectively in 80 patients. Plasma renin activity (PRA; >4 ng/mL/hour) was used as a surrogate of effective arterial blood volume.

Risk factors for hepatic encephalopathy in patients with cirrhosis and refractory ascites: relevance of serum sodium concentration.

Hyponatraemia is common in patients with advanced cirrhosis and is associated with remarkable changes in brain cells, particularly a reduction in myoinositol and other intracellular organic osmolytes related to the hypo-osmolality of the extracellular fluid. It has been recently suggested that hyponatraemia may be an important factor associated with the development of overt hepatic encephalopathy (HE). To test this hypothesis, we retrospectively analysed the incidence and predictive factors of overt HE using a database of 70 patients with cirrhosis included in a prospective study comparing transjugular intrahepatic portosystemic shunts (TIPS) vs large-volume paracentesis in the management of refractory of ascites.

The hepatic apelin system: a new therapeutic target for liver disease.

Unlabelled: Apelin is a peptide that plays an important role in heart physiology and pathophysiology, inflammation, and angiogenesis. We evaluated whether the endogenous apelin system is involved in the pathogenesis of the hepatic remodeling and cardiovascular and renal complications occurring in advanced liver disease. The circulating levels of apelin, the messenger RNA (mRNA) and protein expression of apelin and apelin receptor, the immunohistological detection of apelin and apelin receptor, and the effects induced by the chronic administration of an apelin receptor antagonist on fibrosis and vessel density were evaluated in rats with cirrhosis and ascites and in control rats.

Effects of satavaptan, a selective vasopressin V(2) receptor antagonist, on ascites and serum sodium in cirrhosis with hyponatremia: a randomized trial.

Unlabelled: Hyponatremia in cirrhosis is associated with significant morbidity and mortality and complicates ascites management. Vasopressin receptor antagonists improve serum sodium concentration by increasing renal solute-free water excretion, but their effects on the management of ascites have not been assessed. Our aim was to investigate the effects of satavaptan, a highly selective vasopressin V(2) receptor antagonist, on ascites management and serum sodium in hyponatremic patients with cirrhosis.

Norfloxacin vs ceftriaxone in the prophylaxis of infections in patients with advanced cirrhosis and hemorrhage.

Background & Aims: Oral norfloxacin is the standard of therapy in the prophylaxis of bacterial infections in cirrhotic patients with gastrointestinal hemorrhage. However, during the last years, the epidemiology of bacterial infections in cirrhosis has changed, with a higher incidence of infections caused by quinolone-resistant bacteria. This randomized controlled trial was aimed to compare oral norfloxacin vs intravenous ceftriaxone in the prophylaxis of bacterial infection in cirrhotic patients with gastrointestinal bleeding.

Circulatory function and hepatorenal syndrome in cirrhosis.

The pathogenic mechanism of hepatorenal syndrome is not well established. We investigated the circulatory function in cirrhosis before and after the development of hepatorenal syndrome. Systemic and hepatic hemodynamics and the activity of endogenous vasoactive systems were measured in 66 patients who had cirrhosis with tense ascites and normal serum creatinine levels; measurements were repeated at follow-up in 27 cases in whom hepatorenal syndrome had developed.

Effects of celecoxib and naproxen on renal function in nonazotemic patients with cirrhosis and ascites.

Nonselective inhibition of cyclooxygenase (COX) by nonsteroidal anti-inflammatory drugs frequently induces renal failure in decompensated cirrhosis. Studies in experimental cirrhosis suggest that selective inhibitors of the inducible isoform COX-2 do not adversely affect renal function. However, very limited information is available on the effects of these compounds on renal function in human cirrhosis.

Influence of portal hypertension and its early decompression by TIPS placement on the outcome of variceal bleeding.

Increased portal pressure during variceal bleeding may have an influence on the treatment failure rate, as well as on short- and long-term survival. However, the usefulness of hepatic hemodynamic measurement during the acute episode has not been prospectively validated, and no information exists about the outcome of hemodynamically defined high-risk patients treated with early portal decompression. Hepatic venous pressure gradient (HVPG) measurement was made within the first 24 hours after admission of 116 consecutive patients with cirrhosis with acute variceal bleeding treated with a single session of sclerotherapy injection during urgent endoscopy.

Systemic, renal, and hepatic hemodynamic derangement in cirrhotic patients with spontaneous bacterial peritonitis.

Spontaneous bacterial peritonitis (SBP) is frequently associated with renal failure. This study assessed if systemic and hepatic hemodynamics are also affected by this condition. Standard laboratory tests, tumor necrosis factor alpha (TNF-alpha) in plasma and ascitic fluid, plasma renin activity (PRA) and norepinephrine (NE), and systemic and hepatic hemodynamics were determined in 23 patients with SBP at diagnosis and after resolution of infection.

Increased lipopolysaccharide binding protein in cirrhotic patients with marked immune and hemodynamic derangement.

Intestinal bacterial overgrowth and translocation, both common in cirrhosis with ascites, may lead to the activation of monocytes and lymphocytes, increased levels of proinflammatory cytokines, and enhanced synthesis of nitric oxide present in cirrhosis. Bacterial endotoxin promotes the synthesis of lipopolysaccharide (LPS)-binding protein (LBP), and forms a LPS-LBP complex that binds to CD14. This study was designed to evaluate LBP levels and their correlation to the immune response and the hemodynamic status in cirrhotic patients.

Transjugular intrahepatic portosystemic shunting versus paracentesis plus albumin for refractory ascites in cirrhosis.

Background & Aims: The transjugular intrahepatic portosystemic shunt (TIPS) has been shown to be more effective than repeated paracentesis plus albumin in the control of refractory ascites. However, its effect on survival and healthcare costs is still uncertain.

Methods: Seventy patients with cirrhosis and refractory ascites were randomly assigned to TIPS (35 patients) or repeated paracentesis plus intravenous albumin (35 patients).

Endoscopic treatment versus endoscopic plus pharmacologic treatment for acute variceal bleeding: a meta-analysis.

Endoscopic therapy, involving either injection sclerosis or band ligation, is considered the intervention of first choice for acute variceal bleeding (AVB). Pharmacologic agents have also been shown to be highly effective in the control of the bleeding episode. The purpose of this meta-analysis was to assess whether vasoactive drugs may improve the efficacy of endoscopic therapy (injection sclerosis or band ligation) in the control of AVB and thus increase survival rates.
