Active clinical trials for "Liver Diseases"

The tongue images of patients with gastrointestinal diseases and healthy people will be collected and the tongue image database will be established. Through deep learning and artificial intelligence, early screening models of various gastrointestinal tumors based on tongue images were constructed.

This study is a prospective, observational, single-center, short-term cross-sectional study to assess the repeatability and reproducibility of a set of specified MRI quantitative biomarkers.

This is a multi-center prospective cross-sectional observational study that will assess the prevalence of liver disease in patients dependent on parenteral nutrition (PN) for 4 or more days per week. Liver disease will be determined by the presence of choline deficiency, cholestasis (confirmed by elevated serum alkaline phosphatase (ALP) liver isoenzyme level), and steatosis (confirmed by magnetic resonance imaging-derived proton density fat fraction (MRI-PDFF). The objective of this study is to investigate the presence/prevalence of liver disease in patients dependent on PN (≥4 days a week).

Compensated advanced chronic liver disease (cACLD) commonly indicates severe fibrosis and compensated cirrhosis at risk of developing clinically significant portal hypertension (CSPH) and hepatic decompensation. The presence of CSPH (defined as hepatic venous pressure gradient [HVPG] ≥ 10 mmHg) is the strongest predictor of hepatic decompensation. However, HVPG measurement is invasive, operator dependent, and not widely available. According to the 2021 updated EASL Clinical Practice Guidelines, cACLD patients who did not meet the Baveno VI criteria but had any of the two variables (LSM > 20 kPa or PLT < 150 × 109/L) were suggested to perform screening endoscopy and HVPG measurement. However, the number of cACLD patients with unfavorable Baveno VI status is huge, no detailed risk stratifications existed at this timepoint. This study intended to investigate a novel algorithm to stratify the decompensation risk in patients with cACLD.

This study aims to compare the short and long term outcomes of living donor and deceased donor liver retransplantation. Bearing that in mind, the investigators will retrospectively analyze the files of patients whom underwent a liver retransplantation in Memorial Bahcelievler Hospital Organ Transplantation Center.

To goal is to identify semaphorins that are associated with NAFLD and to investigate their relationship with variable degrees of steatosis and fibrosis.

The purpose of the study is to develop a clinical test based on breath analysis that can be used for disease diagnosis or prognosis.

The purpose of this study is to better understand the main barriers to earlier diagnosis and better management of MASLD/MASH patients and to understand the key barriers to adoption of guidelines. This study is a cross-sectional design, conducted across 5 countries in Europe- France, Germany, Spain, United Kingdom (UK), Italy. Study participants, Hepatologists and other metabolically focused healthcare providers (HCPs), will be recruited to complete a 15 minute self-administered online survey.

The investigators included children with living donor liver transplantation (LDLT) from January 1, 2018 to July 31, 2022 as a retrospective cohort, and the group from August 1, 2022 to June 30, 2023 as a prospective cohort. The investigators collected the demographic and clinicopathological data of donors and recipients, and determined the risk factors of early postoperative delayed recovery of hepatic function (DRHF) by univariate and multivariate Logical regression analyses.

Parenteral nutrition-associated cholestasis (PNAC) is one of the most common complications resulting from administration of parenteral nutrition in neonates. Excess intravenous intake of vegetable oil-based lipid emulsions containing phytosterols is felt to be a major contributing factor. To date, no information is available on plasma phytosterols half-lives in very-low-birth-weight (VLBW) preterm infants with PNAC. In a prospective cohort study, plasma phytosterols (campesterol, stigmasterol and sitosterol) of VLBW preterm infants with PNAC will be measured by gas chromatography-mass spectrometry (GC-MS) during PN administration and also after the stop of intravenous lipid infusion. Plasma phytosterols half-lives will be calculated from the monoexponential decay curves. Blood samples will be weekly collected from 1st to 12th week of life during routine metabolic tolerance analysis or gas-analysis in order to avoid burden of additional phlebotomy. Samples will be collected in ethylenediaminetetraacetic acid-tubes and immediately centrifugated. Plasma will be stored in pyrogallol added-tubes at -20°C until analysis. Saponification reaction will be done using 5-alpha-cholestane as internal standard.
