OBJECTIVETo determine the levels of N-terminal pro-brain natriuretic peptide (NT-proBNP) and evaluate their relationships with cardiac structure and function and liver function in patients with cirrhosis.
METHODSFifty patients with cirrhosis underwent two-dimensional Doppler echocardiography. The cirrhotic patients were divided into groups according to Child-Pugh score:Child-Pugh class A, n=15; Child-Pugh class B, n=20; Child-Pugh class C, n=15. Cardiac dimensions and left and right ventricular functions were evaluated. In addition, the plasma NT-proBNP was detected in the 50 cirrhotic patients and 11 healthy controls.
RESULTSThe levels of plasma NT-proBNP was significantly higher in cirrhotic patients than in healthy controls (240.15+/-80.87 pg/mL vs.55.86+/-20.13 pg/mL, P=0.000).The Child-Pugh class A, B and C groups showed no differences for left ventricular diameter, right ventricular diameter, septal thickness, left ventricular wall thickness, E wave, A wave, aortic annulus diameter, and the value of E/A.However, the left atrial diameter was significantly lower in the A group than in the C group (29.83+/-3.76 mm vs.35.08+/-3.68 mm, P=0.015) and in the B group than in the C group (31.78+/-4.05 mm vs.35.08+/-3.68 mm, P=0.000); there was no significant difference between the A and B groups. The plasma NT-proBNP was significantly lower in the A group than the C group (189.20+/-20.25 pg/mL vs.300.13+/-34.96 pg/mL, P=0.000) and in the B group than in the C group (202.34+/-31.20 pg/mL vs.300.13+/-34.96 pg/mL, P=0.000); there was no significant difference between the A and B groups (P=0.302).The NT-proBNP level was positively correlated with the left atrial diameter and the left ventricular wall thickness (r=0.540, P=0.000 andr=0.309, P=0.029 respectively).In addition, the NT-proBNP showed correlation with Child-Turcotte-Pugh score (r=0.454, P=0.001), albumin level (r=-0.376, P=0.007) and total bilirubin level (r=0.283, P=0.047).
CONCLUSIONs Increased levels of plasma NT-proBNP are related to disease severity in patients with cirrhosis.Furthermore, cardiac dysfunction in patients with cirrhosis may be related to increased plasma levels of NT-proBNP.

2.The lymphatic vascular system in liver diseases: its role in ascites formation.
Clinical and Molecular Hepatology 2013;19(2):99-104
The lymphatic system is part of the circulatory system and plays a key role in normal vascular function. Its failure plays a crucial role in the development and maintenance of various diseases including liver diseases. Lymphangiogenesis (the growth of lymphatic vessels) and changes in the properties of lymphatic vessels are associated with pathogenesis of tumor metastases, ascites formation, liver fibrosis/cirrhosis and portal hypertension. Despite its significant role in liver diseases and its importance as a potential therapeutic target for those diseases, the lymphatic vascular system of the liver is poorly understood. Therefore, how the lymphatic vascular system in general and lymphangiogenesis in particular are mechanistically related to the pathogenesis and maintenance of liver diseases are largely unknown. This article summarizes: 1) the lymphatic vascular system; 2) its role in liver tumors, liver fibrosis/cirrhosis and portal hypertension; and 3) its role in ascites formation.

The aim of this study was to investigate the clinical features of acquired hemophagocytic lymphohistiocytosis (HLH) complicated with hepatic dysfunction. 18 cases of acquired HLH were analyzed. The characteristics of hepatic dysfunction, the relationship between hepatic dysfunction and the cause, as well as prognosis of the acquired HLH were preliminarily analysed. The results indicated that characteristics of hepatic dysfunction in acquired HLH patients were hypoproteinemia, jaundice and increase of L-aspirate aminotransferase (AST) and lactate dehydrogenase (LDH) levels. The level of AST and direct bilirubin (DBil) in the non-malignancy associated hemophagocytic lymphohistiocytosis group were higher than that in malignancy-associated hemophagocytic lymphohistiocytosis group (p<0.05). And the increase of LDH and AST levels indicated poor prognosis (p<0.05). In conclusion, liver damage is a common organ functional disorder in patients with acquired HLH, which may be correlated to the cause and the prognosis of acquired HLH.

4.A hemophagocytic lymphohistiocytosis patient initiated with prominent liver dysfunction: a case report.
Chinese Medical Sciences Journal 2014;29(3):191-193
Hemophagocytic lymphohistiocytosis (HLH) is an aggressive and potentially fatal syndrome that results from inappropriate activation of lymphocytes and macrophages. It is characterized by fever, hepatosplenomegaly, cytopenias, hypertriglyceridemia, hypofibrinogenemia, and pathologic findings of hemo- phagocytosis in the bone marrow or other tissues. We report an adult HLH case admitted to hepatology department.

This study investigated the incidence and severity of hepatic osteody strophy in patients with posthepatitic liver cirrhosis, and the role of hepatocellular injury in bone loss. Twenty-four patients (15 females and 9 males, mean age 49 +/- 13 years) with posthepatitic cirrhosis were enrolled in this study. The control group consisted of 22 healthy age and sex matched adults. The bone mineral density (BMD) was evaluated by dual energy x-ray absorptiometry of the L1-L4 vertebral bodies. A detailed questionnaire was used to assess the epidemiological findings. A statistically significant decrease in BMD of the patients was observed. There were no significant differences in the alkaline phosphatase, parathyroid hormone, calcitonin, 25-hydroxyvitamin D, osteocalcin, free testosterone, luteinizing hormone, follicle stimulating hormone, and estradiol levels, oral calcium intake, urinary calcium, phosphorus and hydroxypyroline excretion between patients and controls. The control group smoked more cigarettes, consumed more coffee and meat, and were exposed the sun light for a longer period than the study group. Multiple regression analysis showed that osteopenia depends significantly on the extent of liver disease. The data shows that the patients with posthepatitic cirrhosis had osteopenia, and that cirrhosis was a direct and independent risk factor.

OBJECTIVEEndogenous hydrophobic bile acids may be a pathogenetic factor of biliary complications after orthotopic liver transplantation (OLT).This study was designed to investigate the effects of hydrophilic ursodeoxycholic acid (UDCA), when administered early after OLT, on serum liver tests and on the incidence of biliary complications.
METHODSA total of 112 adult patients undergoing OLT were randomly assigned to one of two groups for receipt of UDCA (13 to 15 mg/kg/d for 4 weeks, n=56) or a placebo (n=56). All patients underwent serum liver testing and measurement of serum bile acids during the 4 weeks following OLT.Patients with T-tube underwent measurement of biliary bile acids during the 4 weeks following OLT.Biliary complications, as well as patient and graft survival rates, were analyzed during the follow-up period (mean of 65.6 months).
RESULTSAt post-OLT days 7, 21 and 28, the UDCA-treated patients showed significantly lower levels of alanine aminotransferase, aspartate aminotransferase and gamma glutamyl transpeptidase (all P less than 0.05).In addition, the UDCA-treated patients showed significantly lower incidence of biliary sludge and casts within the first year post-OLT (3.6% vs.14.3%; x2=3.953, P=0.047). However, there were no significant differences for the incidence of other biliary complications at post-OLT years 1, 3 and 5.The graft and patient survival rates were also similar between the two groups.
CONCLUSIONUDCA, when administered early after OLT, improves results from serum liver tests and decreases the incidence of biliary sludge and casts within the first postoperative year.

7.Hepatic venous pressure gradient: clinical use in chronic liver disease.
Clinical and Molecular Hepatology 2014;20(1):6-14
Portal hypertension is a severe consequence of chronic liver diseases and is responsible for the main clinical complications of liver cirrhosis. Hepatic venous pressure gradient (HVPG) measurement is the best available method to evaluate the presence and severity of portal hypertension. Clinically significant portal hypertension is defined as an increase in HVPG to >10 mmHg. In this condition, the complications of portal hypertension might begin to appear. HVPG measurement is increasingly used in the clinical fields, and the HVPG is a robust surrogate marker in many clinical applications such as diagnosis, risk stratification, identification of patients with hepatocellular carcinoma who are candidates for liver resection, monitoring of the efficacy of medical treatment, and assessment of progression of portal hypertension. Patients who had a reduction in HVPG of > or =20% or to < or =12 mmHg in response to drug therapy are defined as responders. Responders have a markedly decreased risk of bleeding/rebleeding, ascites, and spontaneous bacterial peritonitis, which results in improved survival. This review provides clinical use of HVPG measurement in the field of liver disease.

With the increased temporal resolution available in dynamic computed tomography (CT) and magnetic resonance imaging (MRI), hepatic arterioportal shunts are now more frequently encountered than in the past. The condition occurs in various hepatic diseases in which portal or hepatic venous flow is compromised. The underlying mechanism and the degree of shunt affect its appearance at dynamic imaging. The dynamic CT and MRI findings have been summarized as early enhancement of peripheral portal veins, and wedge-shaped transient parenchymal enhancement during the hepatic arterial phase. Recognition of arterioportal shunt can suggest the presence of a previously unsuspected disorder and avoids false-positive diagnosis or overestimation of a hepatic disease. Familiarity with the pathophysiology of arterioportal shunt also allows investigation of the hepatic hemodynamic changes occurring in various hepatic diseases.

OBJECTIVETo investigate the effect of enteral nutrition(EN) on liver function and inflammatory response after abdominal operation in patients with liver dysfunction.
METHODSA prospective multicenter study was conducted. Patients requiring EN for at least 5 days after abdominal surgery with at least 1 abnormal liver function index were included. After operations, EN suspensions(TPF-FOS) were administered for 5 days after the return of bowel function with targeted content of 125.52 kJ(30 kcal)·kg(-1)·d(-1) maintained for a minimum of 3 days. Levels of serum pre-albumin, C-reaction protein(CRP), and liver function index were measured and the incidence of systemic inflammatory response syndrome(SIRS) was recorded before operation and 6 days after EN. Occurrence of gastrointestinal discomfort was monitored during the treatment.
RESULTSNo statistically significant difference was found in pre-albumin between preoperative level and post-EN level[(175.94±71.79) mg/L vs.(192.22±91.26) mg/L, P=0.162]. Patients with abnormal level of γ-glutamyl transpeptidase were less after EN compared to the preoperative period(30 vs. 40, P=0.041), as was total bilirubin (3 vs. 9, P=0.034). No significant differences in other indices of liver function were found. Total bilirubin and direct bilirubin decreased after EN support(P=0.000 and P=0.015, respectively). CRP was notably reduced after EN support [(48.74±65.16) mg/L vs.(25.79±23.63) mg/L, P=0.009] and the incidence of SIRS largely declined after EN support(19.0% vs. 10.3%, P=0.059). The incidence of gastrointestinal discomfort was 22.4% on postoperative day 1 and declined to 19.0% on postoperative day 5.
CONCLUSIONFor patients with liver dysfunction, enteral nutrition support with TPF-FOS after abdominal operation can reduce inflammatory response, improve liver function, and maintain serum protein level.
