Active clinical trials for "Liver Cirrhosis"

The main purpose of the present study is to compare the diagnostic performance of three non-invasive stiffness imaging methods (TE, SWE and MRE) in a consecutive cohort of patients with chronic viral C hepatitis or co-infected by HCV+ Human Human Immunodeficiency Virus (HIV).

While methotrexate (MTX) remains a treatment of choice for patients with rheumatoid arthritis (RA), psoriasis (PsO) and psoriatic arthritis (PsA), long-term MTX use has been shown to be associated with liver fibrosis and cirrhosis in these patients. In addition, gut dysbiosis has been found to be associated with liver fibrosis and cirrhosis via the gut-liver axis, underscoring the potential role of gut microbiota and bacterial translocation in the pathogenesis of chronic liver diseases in these patients. In this study, we aim to assess the prevalence of advanced liver fibrosis or cirrhosis among these patients on MTX treatment compared to those without, using transient elastography. We also aim to identify the possible risk factor(s) for advanced liver fibrosis or cirrhosis among them. Further, we aim to characterize the difference in fecal microbiota patterns among these three groups of patients. Using a cross-sectional, prospective cohort design, this study will enroll approximately 600 eligible patients, including 300 patients with PsO/PsA and 300 patients with RA, to examine the following hypotheses: Patients on higher cumulative dose of MTX will have higher prevalence of advanced liver fibrosis or cirrhosis compared to those on lower cumulative dose of MTX; Patients with MTX use will have higher prevalence of advanced liver fibrosis or cirrhosis compared to those without MTX use; The fecal microbiota composition will be different between patients with and without MTX treatment; and The fecal microbiota composition will be different between patients with and without advanced fibrosis/cirrhosis while on MTX treatment.

The purpose of this study is to assess the prevalence of cirrhotic cardiomyopathy in patients with cirrhosis, and to analyze the correlation between the severity of cirrhosis and cardiac dysfunction. To investigate the risk factors for cirrhotic cardiomyopathy, and raise clinicians' awareness of cirrhotic cardiomyopathy, early assessment and intervention to improve long-term outcomes in patients with cirrhosis.

In this study, treatment-naïve HBV-related cirrhosis patients were retrospectively enrolled at the first episode of decompensation (ascites or variceal hemorrhage). Patients were followed up every 6 months until death /liver transplantation or for 5 years. Clinical data from medical records about past history, first decompensated events, second /further decompensated events, HCC, and death/ liver transplantation were retrospectively collected. In this retrospective study, the incidence of re-compensation and its clinical characteristics were mainly explored.

The aim of this work is to study the role of long non-coding RNAs WRAP53 and urothelial carcinoma-associated 1 (UCA1) as potential biomarkers in diagnosis of hepatocellular carcinoma.

The aim of the present work is to study platelet indices ( platelet count - mean platelet volume - platelet distribution width ) as noninvasive predictors in decompensated post hepatitic liver cirrhosis .

The purpose of this study is to investigate the impact of splenectomy coupled with portal-azygous disconnection on hepatocarcinogenesis in patients with post-hepatitic cirrhosis after hepatitis B or C virus infection by retrospective case-control study,We hope to find a new idear and method to prevent or cure HCC.

Little is known about the clinical significance of chronic alanine aminotransferase (ALT) elevation in HIV-infected patients without hepatitis B and C coinfection. Study aim is first to evaluate the prevalence of liver fibrosis and cirrhosis in HIV-infected patients with chronic ALT elevation and no chronic viral hepatitis using non-invasive diagnostic tests and second to find associated factors with significant fibrosis and cirrhosis. In a second longitudinal part we intend to assess fibrosis progression within 1 and 3 years.

Sleep disturbance and sexual dysfunction are common complaints of patients with cirrhosis . The term sleep disturbance describes insomnia, poor quality sleep, circadian rhythm disorders and obstructive sleep apnea and is associated with reduced health-related quality of life (HRQoL) score indices. Sleep and sexual disorders have only been formally evaluated in small studies in these patients and to date, no studies have objectively assessed these patients. In addition, no studies have been performed in these patients after liver transplantation. The investigators' hypothesis is that sleep and sexual disturbance is commonly seen in patients with advanced cirrhosis and improves after liver transplantation. However, despite this, HRQoL remain impaired because of residual sleep disturbance.This study will be unique in providing cross-sectional follow-up of patients with cirrhosis at baseline and after liver transplantation (> 6 months).

As we all know, the early diagnosis and accurate staging of liver fibrosis are very important to reduce the incidence of liver cirrhosis and liver cancer. And the accurate evaluation of hepatic fibrosis is of great significance to the prediction of residual liver function after liver surgery. Therefore, clinicians pay more and more attention to the qualitative and quantitative diagnosis of hepatic fibrosis, liver cirrhosis and hepatic steatosis involved in diffuse liver diseases(such as fatty liver, viral hepatitis, autoimmune hepatitis ). And now, liver biopsy is commonly used as the gold standard for the evaluation of steatohepatitis and fibrosis. However, this test is invasive, has low patient acceptance. So more and more clinicians recommend non-invasive methods to qualitatively and quantitatively evaluate the liver steatosis, fibrosis and cirrhosis in diffuse liver diseases. At present, serum markers, ultrasonic elastography and magnetic resonance imaging have good accuracy in the non-invasive detection and evaluation of liver cirrhosis. However, serum markers are not liver-specific, and a single serum marker is not enough to accurately reflect the degree of liver fibrosis. Furthermore, whether the non-invasive liver fiber diagnostic model is suitable for patients with liver disease in China remains to be further verified. At present, transient elastography has been recommended for the non-invasive staging of hepatic fibrosis by the clinical practice guidelines of the European Association for liver Research and the Asia-Pacific Association for liver Research. But as serum markers, it still has low sensitivity and specificity in the diagnosis of early hepatic fibrosis, and is highly operationally dependent. With the development of MRI technology, some MRI quantitative techniques, such as T1mapping, T2mapping,Intravoxel incoherent motion diffusion-weighted magnetic resonance imaging(IVIM-DWI), dynamic contrast enhanced magnetic resonance imaging(DCE-MRI) can be used to qualitatively and quantitatively diagnosis of liver fat, hepatic fibrosis and cirrhosis. And iterative decomposition of water and fat with echo asymmetry and least squares estimation quantification sequence(IDEALIQ) usually used to evaluate liver fat. The existing research results showed that MRI quantitative techniques has a high value in quantitative diagnosis of advanced hepatic fibrosis and cirrhosis. But it still has some limitations in quantitative diagnosis of early liver fibrosis. And what's more,some of the research results still can not reach a consensus. Therefore, based on the multi-parameter potential of MRI and the characteristics of metabolic evaluation. This study will adjust some of the parameters of MRI quantitative techniques, and through large sample datas, combined with a variety of quantitative techniques to explore the application value of MRI quantitative techniques in the quantitative diagnosis of liver diffuse lesions, especially in the early stage of liver fibrosis.
