Active clinical trials for "Liver Diseases"

Chronic liver disease is a significant health issue among children and it can result in fibrosis, cirrhosis and liver failure. Since the prognosis and monitoring of these diseases are different from each other,, Conventional ultrasonography is preferred for the investigation of chronic liver diseases in children, as it is non-invasive, cheap, feasible and available. Elastography, an ultrasonographic non-invasive procedure that measures tissue stiffness.

COVID-19 and liver injury in patients with or without underlying liver disease: A multi-centre retrospective-prospective observational study. All patients infected with SARS-CoV-2 and admitted to the COVID-19 ward/ICU of Max Hospital Saket (either in East Wing , Max Super Specialty Hospital, Saket or MAX Smart Super Specialty Hospital, Saket) between 1/4/2020 to 30/6/2020 (retrospective data between 1/4/2020- 30/5/2020 & prospective data from approval till 30/6/2020), will be included

In Highly Active Antiretroviral Therapy era, fatty liver has become an important cause of liver function damage in people living with HIV (PLWH). There are a large number of PLWH in China who are infected with hepatitis B virus and hepatitis C virus. HIV, hepatitis B virus, hepatitis C virus, drugs, alcohol, etc. affect each other, which makes the cause, diagnosis, and treatment of liver function damage in PLWH complicated in China. The investigators plan to conduct a large-scale questionnaire survey among PLWH in Zhejiang Province to assess liver function, detect liver Injuries early, and analyze HIV, hepatitis B virus, hepatitis C virus, anti-HIV drugs, alcohol and other factors associate with liver injuries in PLWH, to provide basis for the treatment and prevention of liver disease in PLWH in eastern China.

To further clarify the role of sequence polymorphism in patatin-like phospholipid domain containing protein 3 in the development of nonalcoholic fatty liver disease.

On clinically indicated Cardiovascular Magnetic Resonance studies, native T1-times and extracellular volume of the liver will be assessed and findings correlated with established risk calculators for non-alcoholic fatty liver disease.

Non-alcoholic fatty liver disease (NAFLD) is the most frequent cause of chronic liver disease in our environment. Preliminary data suggest that portal hypertension may exist in the initial phases of NAFLD due to mechanisms that have not yet been elucidated. The clinical relevance of its development in these initial phases is unknown, while in more advanced phases new data are required to confirm the close relationship between portal hypertension and the risk of decompensation described in other etiologies. Likewise, the influence of fibrosis and portal hypertension on the cardiovascular risk of patients with NAFLD is unknown. The aim of the present multicenter project is to characterize the presence of portal hypertension and the mechanisms involved in its development in the different stages of NAFLD, to assess the association between the degree of portal hypertension and the development of portal hypertension-related complications, to know the early cardiovascular risk in the different stages of the disease, and to identify noninvasive biomarkers of the presence and severity of portal hypertension.

The aim of the study is to assess the value of contrast enhanced ultrasound in the evaluation of de novo focal liver lesions in clinical practice, in a prospective multi-center design.

Liver biopsy for the assessment of fibrosis has multiple limitations. Liver ShearWaveTM Elastography may provide a non-invasive, fast, and reproducible alternative for the quantitative assessment of liver fibrosis.

Human immunodeficiency virus (HIV) infection is a major global health issue with up to 40 million people infected worldwide. Due to highly active antiretroviral therapy, mortality related to acquired immunodeficiency syndrome (AIDS) has been reducing in the last decades. However, liver disease remains as an important cause of severe complications and death. Hepatic fibrosis progression is the main responsible for liver-related outcomes in HIV-positive patients. Co-infection by hepatitis B (HBV) or hepatitis C virus (HCV) is highly prevalence in HIV patients. Chronic viral co-infection induces faster liver fibrosis progression compared to mono-infected HIV. However, published data have been reporting presence of significant liver fibrosis in HIV without HBV or HCV infection. This might be related to direct action of HIV in hepatocytes or association with others factors, such as non-alcoholic fatty liver disease (NAFLD). NAFLD is associated with metabolic factors, such as obesity and type-2 diabetes mellitus. However, antiretroviral drugs may induce abnormal body fat distribution (lipodistrophy) and insulin resistance playing an important role on this process. Liver biopsy has been historically considered as the gold standard to evaluate liver injury. However, this painful method presents several limitations. Therefore, several non-invasive methods for estimation of liver fibrosis, such as biomarkers (APRI, FIB-4, FibroTest and FibroMeter) and transient elastography by Fibroscan, have been developed as an alternative to liver biopsy. The diagnostic performance and prognostic value of biomarkers and transient elastography have been validated in patients with chronic liver diseases. However, few data are available in HIV patients, especially in those without chronic viral co-infection. Therefore, patients, medical doctors and scientific community will be beneficiated by the future application of non-invasive methods for estimation of liver injury in clinical practice in HIV patients.

This is a feasibility study, to assess if thermal imaging and/or near infrared imaging will be useful in identifying changes in the peripheral circulation in patients with different stages of liver disease. The aim of this study is to use new and advanced thermal imaging techniques to identify changes in the peripheral circulation and hand temperature in patients with liver disease. These changes could be used as a non-invasive marker of the severity and progression of liver disease. Thermal imaging will also be used to assess the changes in the peripheral vasculature with the use of terlipressin, a drug used as treatment for specific complications of liver disease. Patients with acute or chronic liver disease from any aetiology will be recruited, along with patients without liver disease as healthy controls. Patients with disease or on drugs known to affect the peripheral vasculature will be excluded. All studies will be performed in a ward setting in the Royal Infirmary of Edinburgh. The subjects will be required for up to three sessions, each lasting 30 minutes. The session will involve static thermal images being taken, and video images of the hands warming up after being cooled for 30 seconds in water at a temperature of 7 degrees Celsius. If the patient is receiving terlipressin therapy, static images will be taken before, during and after terlipressin therapy.
