Portal vein thrombosis is defined as non-tumoural obstruction of the portal vein or one of its branches. Its incidence is 0.7 to 2.7 per 100,000 patient-years in the general population, and 4.6 per 100 patient-years in patients with cirrhosis. Histological modificaitions fo the portal vein wall and haemostatic changes have been described in cirrhotic patients. The contribution of these changes, both systemic and local, to the development of portal vein thrombosis is debated. One of the hypotheses put forward on the genesis of portal vein thrombosis is as follows: certain bacterial translocations from the digestive tract, promoted by portal hypertension, contribute to endothelial activation resulting in the release of von Willebrand factor and factor VIII, as well as platelet activation and the coagulation cascade, which is dysregulated by cirrhosis and underlying changes in haemostatic balance. Inflammatory phenomena and NETosis may also be involved. Studies suggest that cirrhotic patients have lesions of the glycocalyx located in the portal area, which may be involved in the development of portal vein thrombosis. Patients with cirrhosis may benefit from the placement of a transjugular intrahepatic portosystemic shunt (TIPS). During the TIPS placement procedure, blood is drawn from the internal jugular vein and the portal vein, allowing for parallel biological analyses. The assumption of this study is that haemostasis and inflammation are disrupted differently at the systemic and portal levels in cirrhotic patients.

In our locality, limited studies have discussed AKI in patients with liver cirrhosis and its outcome, therefore we aim to highlight the incidence, patterns, risk factors, and outcomes of acute kidney injury in patients with liver cirrhosis at Sohag University Hospital.
NCT07492862
Porto-sinusoidal vascular disease (PSVD) is a rare clinical entity characterized by significant portal hypertension in the absence of cirrhosis on liver histology, which may or may not show specific alterations of the portal vein, sinusoids, or hepatic lobular architecture. Currently, diagnosis of this condition necessarily requires a liver biopsy and, despite some differences detected on imaging studies-and particularly on liver and spleen elastography-PSVD remains indistinguishable from cirrhosis using non-invasive tests. Contrast-enhanced ultrasound (CEUS) is an easy-to-perform, repeatable, and cost-effective examination that enables real-time assessment of parenchymal or focal liver lesion perfusion. Moreover, the application of dynamic contrast-enhanced ultrasound (DCE-US-i.e., contrast-enhanced ultrasound followed by quantitative perfusion analysis using dedicated software, such as the VueBox Software that will be used in this study) allows integration of CEUS qualitative assessment with quantitative evaluation of tissue perfusion through analysis of time-intensity curves generated during contrast transit. From this analysis, several perfusion-related parameters can be derived (for example, peak enhancement, time to peak, or area under the curve), which have already proven useful in improving differential diagnosis of focal liver lesions and in predicting treatment response and systemic therapy outcomes. To date, the use of DCE-US for the diagnosis of PSVD has not yet been described; however, based on the underlying histological alterations associated with this disease, it is reasonable to hypothesize that parameters obtained with this technique in the liver parenchyma of patients with PSVD may differ from those measured in patients with liver cirrhosis. The aim of the present project is to apply DCE-US in patients with PSVD and in patients with cirrhosis to evaluate potential significant differences in perfusion parameters, and to assess the feasibility of a non-invasive differential diagnosis between the two conditions using this technique in combination with elastography and bidimensional ultrasound data to develop a multiparametric diagnostic score.

To explore the improvement of emergency and critical care patient management.
NCT07465471
Acute variceal bleeding (AVB) in cirrhosis occurs as a result of portal hypertension and carries a 6-week mortality rate of approximately 10-20%. Standard management includes a restrictive transfusion approach, vasoactive therapy, prophylactic antibiotics, and endoscopic band ligation. Despite this, early rebleeding within the first 5 days still occurs in about 10-20% of patients, and individuals at particularly high risk may benefit from pre-emptive TIPS. However, its real-world use remains limited; one study reported that only 6.7% of eligible patients actually underwent pre-emptive TIPS, primarily due to logistical challenges and limited interventional radiology availability for early, non-emergent TIPS procedures. Midodrine, an oral and fast-acting selective α1-adrenergic agonist, has been shown to enhance the effectiveness of nonselective beta-blockers like propranolol by allowing higher tolerated doses and achieving greater reductions in portal pressure (HVPG), thereby reducing the risk of initial variceal bleeding. However, no studies have evaluated the combination of midodrine with carvedilol-currently a preferred agent-versus carvedilol alone in patients at high risk of rebleeding. To address this gap, we propose a study comparing carvedilol plus midodrine with carvedilol alone for preventing early rebleeding in cirrhotic patients. Individuals with cirrhosis (Child-Pugh 8-13) presenting with hematemesis will be enrolled, stabilized according to APASL guidelines, and after 48 hours randomized to either combined midodrine-carvedilol therapy or carvedilol alone. Participants will be followed for 6 weeks to assess the incidence of early rebleeding.
NCT07459972
This prospective open-label parallel pilot clinical study evaluated the efficacy and safety of physiologically based pharmacokinetic (PBPK)-guided simvastatin dosing in Child-Pugh A and B cirrhotic patients with portal hypertension over a 3-month period. Twenty-two patients were enrolled following screening, and portal hemodynamic, laboratory, and safety parameters were assessed.
NCT07437638
This study aims to develop a practical tool for identifying cirrhotic patients at high risk of hepatic encephalopathy following transjugular intrahepatic portosystemic shunt (TIPS) placement. A retrospective analysis will be conducted on medical records of 624 cirrhotic patients who underwent TIPS from 2011 to 2021. Statistical methods will be applied to screen preoperative routine indicators associated with post-TIPS hepatic encephalopathy risk. A predictive nomogram will be constructed incorporating the screened indicators to estimate individual preoperative risk. The predictive performance will be compared with conventional clinical scoring systems. This tool is intended to facilitate preoperative risk evaluation and targeted management of high-risk patients undergoing TIPS
NCT07437755
Patients with liver cirrhosis have historically received prophylactic transfusions before invasive procedures with high risk of bleeding. The optimal method for establishing the need of blood transfusion before invasive procedures in cirrhotic patients has not been determined yet, and there are not enough scientific data to warrant empirical transfusion. In many surgical and trauma-related contexts, viscoelastic tests, like Rotational Thromboelastometry (ROTEM), offer a comprehensive assessment of hemostasis, and it has been demonstrated to predict bleeding risk more accurately than traditional coagulation tests. The aim of this project is to evaluate the efficacy of a ROTEM-based algorithm in managing the administration of prophylactic blood components to patients diagnosed with decompensated liver cirrhosis undergoing invasive high risk of bleeding procedures. The investigators hypothesized that ROTEM-based decision-making will lead to a reduction in pre-procedural blood component usage, particularly fresh frozen plasma (FFP), compared with standard of care, whilst maintaining optimal clinical outcomes. The investigators will perform a prospective, single-center, randomized controlled clinical trial in a tertiary university hospital in Romania, comparing ROTEM-guided prophylactic blood component administration to standard of care in patients with decompensated cirrhosis and coagulopathy undergoing invasive procedures. Inclusion criteria: adults (aged 18 years or older) admitted with cirrhosis and an indication for high risk of bleeding invasive procedure defined as: transjugular liver biopsy, transjugular intrahepatic portosystemic shunt, endoscopic retrograde cholangio-pancreatography with sphincterotomy, endoscopic polypectomy of polyps more than 1 cm, variceal banding and complex dental extraction. The primary safety endpoint will be the incidence of major bleeding. Secondary endpoints will be the proportion of blood products transfusion, hospital length of stay, in-hospital and 28-day mortality, incidence of minor bleeding, transfusion related adverse reactions, and cost analysis.
NCT07433881
Hepatitis A virus (HAV) superinfection in patients with cirrhosis can precipitate acute hepatic decompensation and significantly worsen outcomes. Although HAV exposure was historically universal in India, recent evidence shows declining natural immunity in adults, particularly in urban populations. Contemporary data on HAV seroprevalence and vaccine immunogenicity in Indian cirrhotics remain scarce. Updated evidence is necessary to inform national vaccination policy for chronic liver disease. This study aims to estimate the prevalence of anti-HAV IgG among adults with cirrhosis and identify predictors of non-immunity. A secondary objective is to evaluate early immunogenicity and durability of a single dose of inactivated HAV vaccine in baseline non-immune patients. This study will generate updated sero-epidemiological data and prospective evidence on single-dose HAV vaccine immunogenicity in Indian cirrhotics, providing essential guidance for HAV vaccination policies in cirrhosis. STUDY DESIGN: Observational cross-sectional study with a nested prospective cohort.
NCT06749340
Reasons such as sleep disorders, depression, decreased independence in daily living activities and decreased quality of life, which are seen in the majority of liver cirrhosis patients, can cause cognitive dysfunction, especially attention. It is known that physical dysfunctions are observed in patients with liver cirrhosis along with cognitive dysfunction. Sarcopenia is the most important of these dysfunctions. Sarcopenia is the progressive, widespread loss of muscle mass, function and strength. The aim of this study is to determine the effects of face-to-face and home-based progressive strengthening exercise program performed 3 times a week for 12 weeks on muscle strength, muscle mass, functionality and cognitive functions in individuals with liver cirrhosis. It is also aimed to test the feasibility and effectiveness of the home-based exercise method in individuals with liver cirrhosis. Another aim of our study is to determine the exercise dose required to improve muscle strength, muscle mass, functionality and cognitive functions in individuals with liver cirrhosis and the duration of treatment effectiveness through follow-up.

NCT00243633
The conventional sonography is frequently used to detect incidental focal liver lesions because of its availability, innocuity and low cost. Nevertheless, sensibility and specificity of conventional sonography does not exceed 70% for tumoral affections. Consequently the interest of this practice must be reconsidered by studying its ratio cost/diagnosis contribution. These limitations of conventional sonography have led to the use of other imaging modalities and invasive or costly procedures such as computed tomography (CT), magnetic resonance imaging (MRI) or biopsy. The availability of real-time contrast-enhanced ultrasound imaging (CEUS) has changed the strategy in the characterization of focal liver lesions, on healthy or cirrhotic liver in a neoplastic context or not, without inconvenience for the patient. The aim of the present study is to evaluate the place of CEUS in term of diagnostic relevance and catch of load cost, in the characterization of focal liver lesions detected but not characterized by CT or conventional sonography.

Globally, cirrhosis and liver cancer carries a huge burden and accounts for about 3.5% (2 million) of all deaths every year. Once decompensated, i.e. development of ascites, variceal bleed, encephalopathy, and jaundice, the life expectancy is markedly reduced to a median of two years. The definitive treatment in this stage, i.e., liver transplantation is limited by cost, lack of donors, and life-long immunosuppression. In addition to complications due to portal hypertension and hepatic insufficiency, decompensated cirrhosis is associated with malnutrition, sarcopenia, immune dysfunction, and impaired regeneration. Patients with cirrhosis are growth hormone (GH) resistant, with reduced insulin-like growth factor, which are linked to malnutrition and poor liver regeneration in cirrhosis. Diverse preclinical and clinical investigations in vitro and in vivo, have shown a benefit of GH in GH deficient, elderly and HIV positive patients. GH therapy in cirrhosis has been shown to improve nitrogen economy and to improve the GH resistance in a small pilot study by Donaghy et al. Also, GH therapy of short duration has shown to increase IGF1 levels, IGFBP-3 levels in patients of cirrhosis. GH therapy has also been shown to improve liver regeneration and protein synthesis after hepatectomy in patients of HCC with cirrhosis. However, there is a scarcity of data on clinical impact of long term administration of GH therapy in patients of cirrhosis. Hence, we undertook the present study to study the effect of growth hormone on clinical outcomes, malnutrition, immune cells and liver regeneration in patients with cirrhosis.
NCT07275554
This study aims to investigate the methylomic features of patients with hepatitis B-related acute-on-chronic liver failure and establish and validate a prognostic risk prediction classification model. The findings are of significant importance for guiding clinical practice and improving patient prognosis. Additionally, a methylomics-based classifier model for liver failure will be developed for disease prognosis analysis and clinical assessment, with the potential to enhance the diagnostic efficiency of liver failure.
NCT07253389
Transjugular intrahepatic portosystemic shunt (TIPS) is a key therapeutic intervention for complications of portal hypertension. However, the risk of post-procedural hepatic encephalopathy (HE) limits its broader clinical application. In the management of gastroesophageal variceal bleeding, the primary goal of TIPS is to reduce the portosystemic pressure gradient (PPG) to less than 12 mmHg (16 cmH₂O), which defines the standard TIPS procedure. The investigators hypothesize that, in patients undergoing TIPS for the prevention of variceal rebleeding, stent underdilation using a 6-mm balloon (underdilated TIPS) will not increase the risk of rebleeding but may reduce the incidence of overt HE and attenuate liver injury. To test this hypothesis, the investigators have designed a prospective, multicenter, randomized controlled trial.
NCT07252401
Acute gastrointestinal bleeding (AGIB) is a common complication in the decompensated stage of liver cirrhosis, of which approximately 70% is acute variceal bleeding (AVB) caused by portal hypertension. Existing evidence suggests that both terlipressin and somatostatin can be used to control AVB in cirrhotic patients, but terlipressin may be the first-line treatment for cirrhotic patients with AGIB complicated by acute kidney injury (AKI). Herein, a multicenter randomized controlled trial (RCT) has been designed to compare the efficacy of terlipressin and somatostatin in the treatment of cirrhotic patients with AGIB complicated by AKI.
NCT05971108
Patients with liver cirrhosis are at high risk of developing hepatocellular carcinoma (HCC) which implies significant mortality. At present current surveillance methods detect hepatocellular carcinomas at a late stage resulting in few treatment options for patients and, in the majority of cases, premature death. The goal of this study is to implement Elecsys® GAAD in real-world hepatocellular carcinoma surveillance for those with liver cirrhosis. The main questions it aims to answer are: * Does the introduction of the Elecsys® GAAD algorithm to the surveillance pathway increase early detection of HCC? * Does the introduction of the Elecsys® GAAD algorithm to the surveillance pathway reduce false positive tests and unnecessary confirmatory investigations? * Does the new surveillance pathway improve adherence? Researchers will compare Elecsys® GAAD with standard of care tests to see if it results in earlier detection of hepatocellular carcinoma and will explore potential improvements to the surveillance pathway.
NCT07183293
This study is a multicenter, randomized, prospective trial designed to evaluate the efficacy and safety of pegylated interferon α-2b (Peg-IFN-α2b) combined with nucleos(t)ide analogues (NAs) versus NAs monotherapy in patients with compensated hepatitis B cirrhosis. A total of 30 patients with compensated HBV-related cirrhosis will be enrolled and randomized in a 2:1 ratio to either Experimental Group 1 (n=20) or Experimental Group 2 (n=10). The treatment regimens consist of Peg-IFN-α2b combined with NAs (ETV/TAF/TMF/TDF) or NAs (ETV/TAF/TMF/TDF) monotherapy.
