Filter by:Background. The main risk factor for the development of hepatocellular carcinoma (HCC) is cirrhosis of any etiology, with an annual risk between 1 and 6%, being currently the leading cause of death in patients with cirrhosis and the third cause of death for cancer in the world. In our country there is little information about the incidence of HCC in this population. It has been shown that there is a change in the gut microbiome (set of genetic material of microorganisms that make up the intestinal bacterial flora) as the severity of the cirrhosis progresses. This change in the microbiome has been associated with clinical decompensation events of cirrhosis. However, there are no previous studies in the world that demonstrate an impact of the change of the microbiome in cirrhosis as a precursor to the development of HCC. Our team has compared the profile of the microbiome in patients with cirrhosis with and without HCC. We observed that patients with HCC present changes in the phylum Firmicutes, genus Fusobacterium and change in the bacteroides / prevotella ratio. This pattern was associated with a pro-inflammatory profile. In murine models, it has been postulated that modulation of the gut microbiome through the use of probiotics could have a clinical role in the prevention of HCC development. This research project aims to answer the following question: in patients with cirrhosis, does the nutritional supplement with probiotics prevent HCC development? Objective: To compare the incidence of HCC through intervention with probiotics in cirrhosis. Methods: A randomized, double-blind, placebo controlled trial of probiotics in patients with Child Pugh A-B cirrhosis at 3-year follow-up. Likewise, the type of microbiome found as a predictor of the risk of HCC development will be evaluated. It will include 280 patients, 140 in each branch. Basal blood and stool samples will be obtained and every 6 months. The typing and quantification of the microbiome in samples of fecal matter will be carried out by amplifying a specific region (V3-V4) of the bacterial 16s rRNA gene. Likewise, the presence of endotoxins (LPS) and cytokines (IL6, TNF alpha) in plasma will be determined to analyze the immune environment and the expression of the TLR4 receptor in mononuclear cells.
A single-center randomized controlled study comparing endoscopic or interventional therapy guided by the hepatic venous pressure gradient (HVPG) , to standard endosopic variceal ligation plus nonselective beta-blocker therapy (NSBB) in patients with esophageal varices due to liver cirrhosis with a history of esophageal variceal hemorrhage.Primary study outcome of the study is variceal rebleeding episodes occurring within the first years after interventions. Second study outcomes of the study are hepatic encephalopathy occurrence, mortality occurrence, liver transplantation or other cirrhosis-related complications.
The aim of this study is to evaluate the diagnostic performance of FEUrea for the differential diagnosis of AKI in patients with cirrhosis and ascites Specifically, the ability of FEUrea to distinguish between ATN versus Pre renal azotemia and HRS.
Sarcopenia is a syndrome characterized by progressive and generalized loss of skeletal muscle mass and strength, shown to be prevalent in adults with cancer and common chronic comorbidities such as liver cirrhosis. The EWGSOP identified a grading for Sarcopenia into pre-sarcopenia (decreased muscle mass with normal strength and physical performance), sarcopenia (decreased muscle mass with decreased strength or performance), severe Sarcopenia (decreased muscle mass, strength and performance) . Sarcopenia has emerged as an independent predictor of poor prognosis in a variety of clinical conditions.Sarcopenia is clinically important because it can affectthe quality of life of patients with cirrhosis . Skeletal muscle mass is not only a good indicator of nutrition in patients with cirrhosis, but also has recently been shown to be closely associated with survival prognosis and postoperative complications inHCC. Combination of sarcopenia and the Model for End-stage Liver Disease (MELD) has been shown to be an excellent model for predicting prognosis in decompensated liver cirrhosis . Most patients awaiting liver transplantation (LT) are more or less in a state of sarcopenia. Several studies have reported that sarcopenia was associated with worse prognosis.In addition, sarcopenia may be associated with a higher risk of post-transplant infection . Assessment of sarcopenia in patients with liver cirrhosis:_ The European Working Group on Sarcopenia in Older People recommended that the definition of sarcopenia include not only low muscle mass but also low muscle function . They recommended cutoff values for muscle mass measurements (7.26 kg/m2 for men and 5.5 kg/m2 for women using dual X-ray absorptiometry, and 8.87 kg/m2 for men and 6.42 kg/m2 for women using bioimpedance analysis, handgrip strength (<30 kg for men and <20 kg for women), and usual gait speed (<0.8 m/s). Aim of the study - To evaluate sarcopenia in different stages of liver cirrhosis by different diagnostic methods. - To identify the prognostic value of CT in the diagnosis of sarcopenia . - To identify effect of sarcopenia inliver transplant candidate. Patients and methods: Type of the study:the study is divided into two parts First part: observational descriptive cross sectional study. Second part: follow up of liver transplant candidate group (pre and post liver transplantation) Duration of study: expected duration of the study will be 1.5 years . The 1st part will include all patients admitted to the department for 1 year fulfill inclusion criteria . 2nd part will be 6 ms follow up after liver transplantation. Study population 1. st part : Patients with liver cirrhosis will be evaluated for the presence of sarcopenia. 2. nd part: - 13 cases of liver cirrhosis already done liver transplantation in AL Rajhiuneversitiy hospital(which data already recoreded) and any cirrhotic pts will be prerared for liver transplantion within six months. - Methods At the study entry, all candidates will be subjected to the following parameters (and 3 month after LT for liver transplant candidates only) - Clinical history - Clinical examination - Abdominal ultrasound - Laboratory investigation: - Liver function tests - Complete blood picture, - Kidney function tests, - Serum glucose, serum Na+ and K+ - Hepatitis markers (HBsAg, HCV-Ab) - Calculate: = Child Pugh score (Pugh et al., 1973) and MELD (Wiesner et al., 2003) scores for assessment ofliver cirrhosis. - Anthropometric measurements: - Triceps skin fold thickness (TSF) . - Measure mid-arm circumference (MAC). - Body mass index - Hand grip to assess muscle strength - Gait speed to assess physical performance - Assessment of sarcopenia using CT scan: - Assessment of sarcopenia using ultrasound: - Assessment of sarcopenia using bioimpedance analysis
This is a pilot study to investigate the feasibility of a novel MRI technique to assess the severity of liver cirrhosis and predict complications based on functionality and perfusion measurements whilst maintaining image quality. The principal objective of this pilot study is to assess liver function and the future risk of complications in patients with cirrhosis, using novel techniques and measures based on free-breathing Dynamic Contrast Enhanced MRI. Specifically the investigators will assess: 1. Whether sufficient data can be generated in patients with cirrhosis whilst maintaining image quality, and 2. The dynamic range of DCE-MRI measures in patients with cirrhosis. This pilot study will, if successful, provide sufficient data to support applications for larger studies to evaluate the clinical utility of a DCE-MRI imaging biomarker in patients with cirrhosis.
Atrial fibrillation (AF) is the most frequently encountered cardiac arrhythmia. Emerging data suggests that common genetic variants are associated with the development of AF. The main feature of the structural remodelling in AF is atrial fibrosis and is considered the substrate for AF perpetuation. Genome-wide association studies suggest that AF-susceptibility variants may modulate atrial fibrosis. However, the association between atrial fibrosis and genetic polymorphisms in humans has not yet been specifically investigated. In this study, we plan to investigate the relationship between genetic polymorphisms, atrial fibrosis and other components of thrombogenic substrate in patients with non-valvular AF. Primary objectives of this study are to assess associations between (i) polymorphic genetic variants and atrial fibrosis (detected by magnetic resonance imaging), (ii) polymorphic genetic variants and components of thrombogenic substrate (inflammation, endothelial function, prothrombotic state, atrial functions).
Decompensated liver cirrhosis is one of the life-threatening complication of chronic liver disease. Liver transplantation currently is the only effective method that can improve the survival of these patients. However, the severe shortage of donor livers, high cost, and potential serious complications have restricted the availability of liver transplantation.Umbilical cord mesenchymal stem cells (UC-MSC) has been generally shown to be safe and effective for liver diseases in some pre-clinical and clinical studies. This study aim to evaluate the safety and efficiency of human umbilical cord mesenchymal stem cell transfusion in patients with decompensated liver cirrhosis, and explore the best protocol of MSC transfusion.
Injury to the heart, which may occur following a heart attack or owing to the mechanical effect of high blood pressure, leads to scarring (fibrosis) of the heart muscle. Fibrosis of the muscle can cause impaired pumping of the heart, which can lead to heart failure, and the abnormal conduction of electrical signals through the heart. This may in turn lead to abnormal, potentially fatal, heart rhythms. Currently, scarring of the heart muscle cannot be reversed and is generally progressive. A previous clinical study found that participants who received injections of immunomodulatory progenitor cells (iMP cells, "Heartcel") showed a reversal of heart muscle scarring when the cells were injected into heart muscle during coronary artery bypass graft (CABG) surgery. However, the previous trial was a small scale study and did not have a control group. The aim of this study is to perform a larger scale investigation with 50 participants compared to the previous trial of 11, and split the 50 participants into two groups - a test group and a control group, so that a direct comparison may be made between the two groups.
