Filter by:The proposed of this randomized, double blinded, placebo-controlled study is to assess the effect of SAMe compared to placebo in patients with alcoholic cirrhosis Child Class A and B. The primary objective of the study is to test relationship between SAMe (S-adenosylmethionine) supplement on liver function. The hypothesis is that SAMe supplement will improve liver function in patients with alcoholic liver disease. The improvement in liver function will lead to the reduction in all-cause mortality in patients with alcoholic cirrhosis in those who receive SAMe supplement when compared to those receiving placebo.
Alcohol is the common precipitating factor for both cirrhosis of liver as well as alcohol related chronic pancreatitis. However, in real life clinical setting, clinicians do not frequently see many cases of symptomatic pancreatitis in patients who present with features of cirrhosis of liver. On the contrary, in some patients presenting with alcohol related chronic pancreatitis, evidence of cirrhosis of liver is observed on imaging without other clinical features of cirrhosis.
In previous studies, the investigators used retrospective analysis of cases of acute upper gastrointestinal bleeding in patients with liver cirrhosis from the Fifth Medical Center of the General Hospital of Beijing PLA, China from January 2018 to May 2019. The investigators performed univariate and multivariate analyses of rebleeding risk and death risk based on all data. Then, based on the analysis of 85% of the sampled data, the investigators randomly selected 85% of the patient data to build a model, and then used the remaining 15% of the patient data for model validation. Re-bleeding risk scores and death risk scores were established, respectively. This study intends to prospectively verify the two risk scoring systems described above. After statistical calculations, about 500 patients with liver cirrhosis who plan to undergo emergency gastroscopy for acute upper gastrointestinal bleeding within the next 5 months at the Fifth Medical Center of Beijing General Hospital of China performed in adult patients. The investigators will exclude patients with incomplete or lost follow-up records. Perform patient self-control,using the existing upper gastrointestinal bleeding risk scores (AIMS65, Rockall, and Blatchford) and the previous scoring system model separately, compared with the actual rebleeding rate and mortality for comparison. To verify and revise the rebleeding risk score and death risk score that the investigators constructed earlier.The data were statistical processed by a professional statistician. The establishment of an acute upper gastrointestinal bleeding rebleeding and death risk scoring system for patients with liver cirrhosis can help distinguish patients with high or low risk of rebleeding or death to determine the patient's treatment needs.
Non-Alcoholic Fatty Liver Disease (NAFLD) and Non-Alcoholic SteatoHepatitis (NASH), are a frequent complication of type 2 diabetes and obesity. This disease has been linked with an increased morbidity and mortality, in particular cardiovascular disease and hepatic complications (cirrhosis and hepatocellular carcinoma). NAFLD is covered different liver damage in ascending order: steatosis, Non-Alcoholic SteatoHepatitis (NASH), fibrosis, and finally cirrhosis. Mostly, fibrosis has a determining role in the patient's status health. The fibrosis prevalence rate may reach up to 15 % of people with type 2 diabetes. The purpose of the study is to screen hepatic fibrosis for patient with type 2 diabetes. To be sure of the status of the disease, the gold standard procedure remains liver biopsy. However, it's an invasive procedure and it's a challenge to perform this kind of medical procedure to every patient with NAFLD. Some alternative procedure exists, called FibroScan that gives some indication of liver fibrosis status. Unfortunately, every diabetologist hasn't this equipment in his medical office. The investigators propose to evaluate two non-invasive biological fibrosis tests, called eLIFT and FibroMeter. The results of these two diagnostic tests will be compared to FibroScan and to liver biopsy results.
Due to providing valuable clinical information while being minimally invasive, blood-based testing will most likely be a prerequisite for future large-scale screening of high-risk populations. As a variety of pathological processes, including carcinogenesis, may cause changes in both the concentration and the structure and spatial arrangement of body biomolecules, the spectroscopic analysis of blood-based derivatives appears to be an appropriate tool for the early detection thereof. The differences observed in the spectral response of healthy individuals and patients may also be specific to a particular type/stage of the disease and, thus, may serve as a reliable diagnostic marker. In order to find sufficiently specific and sensitive biomarkers of early stages of degenerative and cancerous diseases, the co-applicant group at the Department of Analytical Chemistry, University of Chemistry and Technology Prague (UCT Prague), developed a unique approach for the spectroscopic analysis of blood plasma. Using the highly specialized, structure-sensitive methods of chiroptical spectroscopy (electronic circular dichroism - ECD, Raman optical activity - ROA) combined with conventional infrared (IR) and Raman spectroscopy, the first pilot studies yielded promising results with respect to the identification of spectral markers for pancreatic cancer, colon cancer and type 1 diabetes mellitus. In addition, metabolomics appears to be a very progressive approach to finding potentially suitable molecules to distinguish between healthy and cancer-affected individuals. Therefore, the investigators believes that this multimodal approach will allow for the identification of hepatocellular carcinoma (HCC). In our research, the focus will be on the identification of novel biomarkers in blood plasma that would exhibit sufficient sensitivity and specificity to detect early and potentially curable HCC stages, and that would be potentially useful for routine screening of this disease in well-defined at-risk groups.
Hepatocellular carcinoma (HCC) is the fifth most common cancer. Patients with HCCs usually have a poor prognosis. Hepatocarcinogenesis is an intricate and multistep process. Detecting and staging early HCC in patients with liver cirrhosis are still challenging for imaging techniques. Contrast-enhanced ultrasonography (CEUS) and gadoxetic acid-enhanced magnetic resonance imaging (EOB-MRI) are widely used in clinical practice. EOB-MRI has advantages of high detecting rate for small lesions, high sensitivity of hepatobiliary phase and extensive image information. Sonazoid has the advantage of offering a unique post-vascular phase, also called the Kupffer phase. Therefore, malignant tumors with few or no Kupffer cells appear as contrast defects, with respect to the relatively well-enhanced surrounding liver in the postvascular phase. The diagnostic efficacies of these two imaging methods have not been well studied. Therefore, the purpose of this study is to compare the efficacies of Sonazoid-CEUS and EOB-MRI in patients with high risk of HCC, and to compare the detection ability for malignant tumors by Kupffer phase and hepatobiliary phase.
This study is to investigate the clinical efficacy and safety of three types of nucleotide/nucleoside analogues in treatment of hepatitis b virus related compensated cirrhosis.
Acquired dysfunctional immunity in cirrhosis predisposes patients to frequent bacterial infections contributing to disease progression and may lead to the development of acute-on-chronic liver failure (ACLF). Spontaneous bacterial peritonitis (SBP) is one of the most frequent infections in cirrhosis and therefore a trigger for ACLF. ACLF is characterized by systemic inflammation even in the absence of confirmed infection and associated with poor outcome. The source of ascites infection, especially in case of culture-positive SBP and bacterascites, is suspected to be bacterial translocation from gut. In decompensated cirrhosis, data on the gut microbial translocation in different circulatory compartments is limited. Moreover, the link between gut microbiome and systemic inflammation in liver disease has still not established. The transjugular intrahepatic portosystemic shunt (TIPS) is applied to treat portal hypertension which frequently leads to intestinal bleeding, life-threatening esophageal bleeding and ascites. Under the procedure of TIPS, the vein blood samples in different compartments (superior mesenteric vein, portal vein and hepatic vein) from patients with decompensated liver cirrhosis are available. Metagenomic next-generation sequencing (mNGS) is a promise approach for the diagnosis of infectious disease because a comprehensive spectrum of potential causes (viral, bacterial, fungal, and parasitic) can be identified by a single assay. Previous study reported that mNGS of cerebrospinal fluid can be applied to diagnosis of meningitis and encephalitis. Comparing to traditional bacterial culture method, mNGS method is more sensitive and rapidly in pathogen detection. Therefore, the circulating microbiome in different compartment can be characterized by means of mNGS. Here, the study aim to investigate the circulating microbiome from superior mesenteric vein (first venous outflow in gut-liver axis), hepatic vein (liver outflow), peripheral vein and ascites from patients with decompensated liver cirrhosis receiving TIPS. Before TIPS, fecal sample and unary sample are collected. And mNGS method is performed to identify the pathogen in ascites,fecal and blood samples in a single center. Ultimately, the study aim to build up the link between gut microbiome translocation and liver disease.
Liver cirrhosis with the further development of portal hypertension implies structural and vasculature alteration in the portosplenic circulation. Esophagogastroduodenoscopy is the standard of care for the detection and treatment of esophageal varices, as esophageal varices serve as a surrogate for estimating a portal pressure gradient > 10 mmHG. Endoscopic ultrasound evaluation allows the detection of peri-esophageal collateral veins, perforating veins and para-esophageal collateral veins, which has demonstrated to be effective for the prediction of esophageal varices recurrence after variceal eradication. The investigators aimed to compare esophagogastroduodenoscopy versus endoscopic ultrasound evaluation for the early diagnosis of portal hypertension in cirrhotic patients.
Acute kidney injury (AKI) is a common complication, occurring in approximately 20% of hospitalized cirrhotic patients and has a significant negative impact on patients' outcomes according to either the initial stage (at the time of the first fulfillment of AKI criteria), or the peak stage (at the peak value of serum creatinine concentration during hospitalization). Among all the precipitating factors to cirrhotic AKI, acute gastrointestinal hemorrhage is a common cause that leads to a decrease in effective arterial blood volume in the hyperdynamic circulatory status of cirrhosis. However, there is still lack of optimal predictors to developing AKI in cirrhotic patients suffering from acute GI bleeding. A number of biomarkers associated with AKI were recently described. Some studies have shown that these novel biomarkers increase with the severity of liver injury and are predictive of clinical outcomes. However, the effective prediction, definitive diagnosis and differentiation of AKI by these biomarkers are still controversial. Furthermore, there is no clinical studies focus on the applicability and potential alteration in the setting of acute gastrointestinal hemorrhage in patients with cirrhosis. Aim and significance: In this study, we aim to investigate the capability of novel renal biomarkers in predicting development of acute kidney injury, differentiating causes (between pre-renal AKI, acute tubular necrosis, and hepatorenal syndrome), and predicting the response to renal treatment as well as the hepatic and overall outcomes in patients with cirrhosis suffering from acute gastrointestinal hemorrhage.
