Active clinical trials for "Liver Cirrhosis"

Cirrhotic patients may be at high risk for esophageal cancer. Endoscopic resection is the standard treatment for superficial tumors. However, cirrhosis might be associated with upper gastrointestinal bleeding, particularly in case of portal hypertension or coagulopathy. This study aims to assess safety, efficacy and methods to prevent potential complications in cirrhosis or portal hypertension context for esophageal endoscopic resection. This retrospective multicentric French-Belgian study includes all consecutive patients with cirrhosis or portal hypertension who underwent esophageal endoscopic resection from January 2005 to 2021.

In recent years, several scoring systems have been developed aimed at predicting early post-LT graft function. However, many of them showed poor efficacy when long-term survivals were tested. Moreover, the necessity to find an easy-to-use score represents another obstacle, with several scores composed by numerous, difficult to find, variables. Recently, the pre-LT Balance of Risk (BAR) and the post-LT Comprehensive Complication Index (CCI) have been created, but their external validation and integration in this setting is lacking. This study aims at constructing an easy-to-use score system based on the combination of a small number of pre- and immediately post-liver transplant (LT) independent variables, in order to accurately predict long-term graft survival after LT.

This is a phase IV, open-label, prospective cohort study for 7 days.The recommended starting dose of tolvaptan is 15 mg daily orally. The dose may be titrated on the next day at 15 mg intervals up to 60 mg daily according to the serum sodium level response.Serum sodium level, change in sodium level from baseline, quality of life (EQ-5D-3L), change in body weight, edema, renal function, mortality and liver-related complications on day 7 and day 30 to evaluate the efficacy of tolvaptan in cirrhotic patients with hyponatremia.

The overall aim of this study is to validate a quantitative digital tool for staging liver fibrosis in biopsies from chronic human liver diseases and then evaluate it prospectively in patients.

This study is designed as a hospital-based cross-sectional and randomized placebo-controlled intervention trial. One hundred and fifty patients with either cirrhosis or cirrhosis combined with hepatocellular carcinoma (HCC) who meet the inclusion criteria will be recruited from Taichung General Veterans Hospital. One hundred patients will be randomly assigned to either the 1) placebo group (n = 25); 2) vitamin B-6 group; (50 mg/d, n = 25); 3) glutathione (GSH) group (500 mg/d, n = 25); or 4) vitamin B-6 (50 mg/d) plus GSH (500 mg/d) group (n = 25) for 3 mo. Data on demography, anthropometry and medical history will be collected. Patients with cirrhosis or cirrhosis combined with HCC will have fasting blood drawn in the clinics. Additionally, patients who participated in the intervention study will have blood drawn at month 0, 1, 2 and 3 during intervention period. Hematological measurements, plasma vitamin B-6 status, GSH, inflammatory markers, homocysteine, cysteine, SAM, SAH, oxidative stress indicator, oxidized GSH and GSH related antioxidant enzyme activities will be analyzed.

This observational study will evaluate the predictive value of rapid virological response (RVR) and early virological response (EVR) on sustained virological response (SVR) by stage of liver fibrosis in treatment-naïve patients with chronic hepatitis C genotype 1 initiated on treatment with Pegasys (peginterferon alfa-2a) and Copegus (ribavirin). Patients will be followed for 48 weeks of treatment and up to 24 weeks of follow-up.

Living donor liver transplantation (LDLT), involves complex systems and processes of care that are particularly vulnerable to medical errors and preventable complications. This ancillary study of the Adult-to-Adult Living Liver Transplantation Cohort Study (A2ALL) will focus on conducting a proactive, systematic, and comprehensive assessment of the vulnerabilities in the systems and process of LDLT care to reduce medical errors and preventable complications thereby improving the safety of LDLT care. This project will address an important gap in the knowledge needed to achieve high quality and safe LDLT care of patients by developing a process to: 1) proactively, systematically and comprehensively identify areas of vulnerabilities in LDLT care that can result in medical errors, 2) design and implement solutions to mitigate these weaknesses, and 3) evaluate the effectiveness of these solutions to improve the safety of LDLT care by measuring clinical and process outcomes before and after solution implementation across four A2ALL participating transplant centers

Cirrhotic patients are predisposed to intestinal dysmotility, bacterial overgrowth, and increased intestinal permeability all leading to an increase in bacterial translocation and increased endotoxemia. Rifaximin is an antibiotic that is virtually non-absorbed after oral administration and exhibits broad spectrum antimicrobial activity against both aerobic and anaerobic gram-positive and gram-negative microorganisms within the gastrointestinal tract. It has been suggested that oral prophylactic antibiotics or bowel decontamination might improve long-term outcomes in patients with cirrhosis. The aim of this study was to explore the suitable dose of rifaximin to alleviate endotoxemia and prevent the complications of advanced cirrhosis.

The portal vein thrombosis (PVT) can complicate medical conditions like liver cirrhosis (LC), neoplasms, myeloproliferative diseases, thrombophilic genotypes, infections, inflammatory diseases, trauma and surgery. LC is an important predisposing disease and is responsible for about 20% of all cases. However, data regarding the PVT in cirrhosis are insufficient. Early studies have shown that, in absence of hepatocellular carcinoma (HCC), the PVT can occur in approximately 10% of cirrhotic patients. Most of studies are in support of a prevalence between 5 and 20% of patients with LC. A study in transplant recipients, has documented that in variable etiology cirrhosis, the PVT was present in 15.7% of patients, a higher percentage was found in patients with liver cancer (34.8%), while primary biliary cirrhosis (7.9%) and sclerosing cholangitis (3.6%) are less frequently complicated by PVT. The PVT development is due to stagnation in the portal circulation, but alterations in the sense of inherited or acquired pro-coagulant may favor its appearance. The causal association of PVT with bleeding and bowel infarction suggests that the PVT may reduce survival in cirrhosis, but data are lacking on this issue. It is also not known whether asymptomatic patients with PVT have a different survival compared to cirrhotic patients without PVT. Further studies should be conducted to clarify this issue. Likewise, prospective studies are needed to better identify risk factors predisposing to PVT in LC patients as well as to clarify the relationship between cirrhosis severity and PVT. The impact of PVT on the natural history of cirrhosis is an issue today still debated. The PVT not only favour life-threatening complications (gastrointestinal bleeding and mesenteric thrombosis) but could also contribute to a deterioration of liver function by reducing portal flow. Obtaining such information would be of crucial importance considering that the evidence of increased mortality related to PVT in liver cirrhosis may indicate the need for randomized controlled trials to clarify the potential effectiveness of anticoagulant therapy to improve the survival. To this purpose it's proposed to establish an Italian register of patients with cirrhosis. In the second phase of the project is planned a 2-years follow-up program in order to assess whether the PVT be an additional risk factor for mortality or deterioration of the natural history in patients with cirrhosis.

Cirrhotic patients have a high incidence of abdominal wall hernias. Ascites and sarcopenia are risk factors to development of bigger hernias and frequent need for urgent surgery due parietal complications. However, hernia surgery is usually delayed in cirrhotic patients because of high morbidity and mortality. Methods: A prospective study of cirrhotic patients with abdominal wall hernia during January 2009 to November 2014. Demographics, characteristics of underlying liver disease, type of hernia, complications and mortality of 246 enrolled patients were collected. Elective hernia repair was performed in 57 unselected patients, 186 patients were kept in clinical follow up. During follow up urgent hernia surgery was performed when unavoidable
