Bosentan for Treatment of Hepatopulmonary Syndrome in Patients With Liver Cirrhosis
Hepatopulmonary SyndromeLiver CirrhosisThe most common observed cause of gas exchange abnormalities and hypoxemia in cirrhosis is the hepatopulmonary syndrome (HPS) with a reported prevalence of 20-47% in patients with hepatic impairment and cirrhosis. HPS is by far the most frequent respiratory complication of cirrhosis. It is a progressive disease leading to significantly increased mortality. Up to date, the only therapeutic option is liver transplantation. The study hypothesis is that administration of bosentan in patients with liver cirrhosis suffering from hepatopulmonary syndrome improves gas exchange. 18 patients with liver cirrhosis fulfilling criteria of HPS according to the ERS task force criteria will be included in this block randomized, double-blind, placebo controlled study (12 patients will be treated with bosentan, 6 with placebo). Patients will receive bosentan 62,5mg b.i.d. for 4 weeks and 125 mg b.i.d. for 8 weeks or placebo. The duration of the treatment phase of the study is 12 weeks. The primary endpoint is the alteration of gas exchange after 3 months of therapy. The expected duration of the study is 2 years.
Advanced Chronic Liver Disease Screening by Transient Elstography in Patients Hospitalised in a...
Psychiatric DisorderPsychiatric Hospitalization2 moreScares data exists concerning the prevalence of chronic liver diseases in people with psychiatric disorders. There are still many barriers to screening and linkage to care for patients having somatic illness. Moreover follow-up of these patients may be difficult because of poor access to care, sometimes marginalization, and insufficient compliance with health programs. The aim of this study is to asses acceptability of of advanced chronic liver disease screening by transient elstography (Fibroscan ®) in patients hospitalised in a psychiatric unit.
Liver Regeneration Therapy Using Autologous Adipose Tissue Derived Stromal Cells
Liver CirrhosisMesenchymal stem cells have the capability to differentiate into hepatocytes and will be useful for liver regeneration. Adipose tissue is relatively enriched with mesenchymal stem cells compared to bone marrow tissue. In this trial, eligible liver cirrhosis patients will receive autologous adipose tissue derived stromal cells which include such mesenchymal stem cells.
Investigational Microbiota Restoration Therapeutic for Hepatic Encephalopathy
Hepatic EncephalopathyCirrhosis1 moreIndividuals with cirrhosis are likely to develop overt hepatic encephalopathy for which diagnostic modalities and treatment options are limited. The purpose of this study is to determine if individuals with cirrhosis who experience hepatic encephalopathy would benefit from investigational microbiota restoration therapy due to their inherent cognitive alterations. Analysis for a correlation between changes in microbiome composition and specific blood biomarkers could allow for earlier diagnosis of HE which could then be treated earlier and with novel treatments.

Pulmonary Function Tests Study in Cirrhotic Patients With and Without Hepatocellular Carcinoma
Pulmonary Complications of Liver Cirrhosis and HCCCirrhosis is a terminal image of chronic liver disease. During the progression from the compensation period to the decompensation period, various complications occur, and the life prognosis is significantly reduced. In recent years, medical treatment for liver cirrhosis has made marked progress. Liver cirrhosis may occur as an end result of manifold infectious, toxic, metabolic, or autoimmune conditions such as viral hepatitis, alcoholism, non-alcoholic steatohepatitis, autoimmune hepatitis (AIH), primary sclerosing cholangitis (PSC), primary biliary cholangitis (PBC), or a variety of storage disorders such as hemochromatosis, Wilson's disease, and alpha-1-antitrypsin deficiency. Worldwide, hepatocellular carcinoma (HCC) is a universal problem and its epidemiological data showed variation from place to place. HCC represents the sixth most common cancer worldwide. In Egypt, it represents the fourth common cancer. Egypt ranks the third and 15th most populous country in Africa and worldwide, respectively. HCC is a commonly diagnosed cancer in males and females. It can lead to multi-organ failure including the respiratory system. Pulmonary function tests (PFTS) are important as an investigation and monitoring of patients with respiratory pathology. They provide important information relating to the large and small airways, the pulmonary parenchyma, and the size and integrity of the pulmonary capillary bed. Although they do not provide a definite diagnosis, different patterns of abnormalities are seen in different respiratory diseases which help to establish the diagnosis.

Liver CirrhosisThe proportion of HCV infected patients over age 65 years in Western countries is increasing. This growth and the advent of new antiviral therapy bring into the question the real world efficacy and safety of the combination of Sofosbuvir and Simeprevir (SOF/SMV) plus a flat dose of ribavirin (RBV) in elderly patients compared to younger patients.
Granulocyte Colony Stimulating Factor And Growth Hormone In Cirrhosis Of Liver: An Open Label Study...
CirrhosisCirrhosis of liver is a leading cause of morbidity and mortality worldwide . Complications including ascites, spontaneous bacterial peritonitis (SBP), variceal bleed, hepatic encephalopathy, hepatorenal syndrome (HRS) and development of hepatocellular carcinoma (HCC) have poor prognosis and further decreases the survival in these patients. It has been believed that cirrhosis is irreversible and that treatment should focus on preventing the progression of liver fibrosis/dysfunction and its complications. Currently the only effective treatment is liver transplantation, an increasingly limited and expensive resource especially in developing countries. Furthermore, transplantation comes with a requirement for lifelong immunosuppression, and considerable long-term side effects that include chronic renal failure, post-transplant lymphoproliferative disease, and cardiovascular complications. Short of liver transplant, recently, reports of unexpected plasticity in adult bone marrow have raised hopes that stem cell therapy may offer exciting therapeutic possibilities for patients with end stage liver diseases. It has been shown that in response to acute or chronic liver damage, bone marrow derived stem cells can spontaneously populate the liver and differentiate into hepatic cells. Animal and human studies suggested that such cells might contribute to the regeneration after different kinds of liver injuries . In animal models, after liver injury, bone marrow-derived circulating pluripotent cells have been reported to participate in liver repopulation with both non-parenchymal cells and hepatocytes. This repopulation process, however, seems to be highly dependent on the type of liver injury and experimental conditions. Fusion with hematopoietic cells has been substantiated as a mechanism by which hepatocytes can regenerate, and studies have demonstrated improved liver histology and survival in patients with cirrhosis following mobilization of bone marrow stem cells by granulocyte-colony stimulating factor (G-CSF) . Three recent studies have demonstrated G-CSF induced mobilization of bone marrow stem cells (CD34 cells) in peripheral blood and their subsequent increase in liver tissue and improved survival in patients with alcoholic hepatitis and acute on chronic liver failure (ACLF) . However there is insufficient data on whether G-CSF improves survival and prognosis in patients with cirrhosis. Also, Malnutrition is commonly seen (60-70%) in cirrhotics and have adverse prognosis on its outcome . The protein catabolic state of cirrhosis is associated with severe growth hormone (GH) resistance, with low levels of insulin-like growth factor (IGF)-I and its major binding protein (IGFBP)-3 . GH therapy in cirrhosis have been shown to improve nitrogen economy and to improve the GH resistance in a small pilot study. Also, GH therapy of short duration has shown to increase IGF1 levels, IGFBP-3 levels in patients of cirrhosis . GH therapy has also shown to improve liver regeneration and protein synthesis after hepatectomy in patients of HCC with cirrhosis . However there is scarcity of data on clinical impact of long term administration of GH therapy in patients of cirrhosis.
