Filter by:Research has proven that large varices can be treated with beta-blockers (a type of anti-hypertensive medication) to reduce the pressure in the veins. The management of small varices is still uncertain. This study aims to discover if beta blockers can be used in this setting. We hypothesize that beta blockers will reduce the risk of bleeding from small varices from 20% to 10% over a period of 3 years, resulting in significant cost savings to the NHS from better patient outcomes.
The goal of this compassionate access program is to provide early access to REP 2139-Mg for patients with HBV mono-infection or HBV / HDV co-infection who either have advanced (decompensated) cirrhosis or who have failed to response to other other antiviral agents either approved or under development and who are in danger of progressing to decompensated cirrhosis. This compassionate access program will provide access to a once weekly regimen of subcutaneously (SC) administered REP 2139-Mg for a period of 48 weeks with the goal of achieving functional cure of HDV and or HBV, with the reversal of liver disease in the absence of antiviral therapy. The safety, tolerability and efficacy of SC REP 2139-Mg will be monitored during and after therapy
The aim of this study is to evaluate patient and consultant experiences with phone consultations for endoscopy-related outpatient appointments during the COVID-19 outbreak.
Chronic peripheral and splanchnic vasodilatation are the hallmark hemodynamic abnormality in cirrhosis and contribute to the pathogenesis of portal hypertension. Alterations in intestinal motility and bacterial overgrowth in gut may predispose to the development of bacteraemia and endotoxaemia in cirrhotic patients which play a role in the hyperdynamic circulatory syndrome of cirrhosis. Probiotic therapy is aimed at changing the make-up of the indigenous microflora by administering specific strains of non-pathogenic and potentially beneficial microflora. In this study, the investigators hypothesize that a modification in the composition of the endogenous digestive microflora by oral bacteriotherapy with high potency probiotic preparations could be a safe way to regulate the portal pressure. As there is a relative paucity in effective pharmacological treatment for portal hypertension, these novel and innovative therapy might provide important alternative or adjunct therapy to beta blockers in the clinical management of patients with portal hypertension. Aims and objectives To study in patients with cirrhosis and large varices whether probiotics and/or norfloxacin given for 2 months : 1. achieve a reduction in HVPG 2. alter the endotoxin and cytokine levels, and improve systemic inflammatory responses 3. well tolerated. Inclusion criteria: Consecutive patients of cirrhosis with portal hypertension who fulfill the following criteria: 1. Diagnosed cases of cirrhosis (by clinical, biochemical and radiological criteria with or without liver biopsy) 2. No history of upper GI bleeding in the past 3. Endoscopically documented large esophageal varices Exclusion criteria 1. history of gastrointestinal bleeding 2. patients who have received beta blockers for portal hypertension in the past 6 weeks. 3. hepatic encephalopathy 4. ongoing bacterial infection, 5. Spontaneous bacterial peritonitis 6. active alcoholism or illicit drug abuse 7. alcoholic hepatitis 8. Treatment with antibiotics in the preceding 2 weeks. 9. presence of hepatocellular carcinoma, 10. portal vein thrombosis 11. serum creatinine>1.5 mg/dL, 12. treatment with vasoactive drugs in the past 6 weeks, 13. history of arterial hypertension, congestive heart failure or arterial occlusive disease, and 14. Refusal to participate. 15. Active smokers. Study plan: Ethical approval will be obtained prior to study initiation. Patients presenting to Department of Gastroenterology, GB Pant Hospital will be recruited in the study. Patients will be evaluated regarding the eligibility for the study. After being found eligible for the study, if the patient agrees to participate in the study, a signed informed consent will be obtained. Baseline HVPG will be measured in all patients and then they will be randomized into 3 groups:. 1. Group 1: Beta blockers + placebo 2. Group 2: Beta blockers + Norfloxacin (400mg BD) 3. Group 3: Beta blockers + probiotics. (one sachet of VSL#3 BD) 30 patients will be enrolled into each group. The treatment will be continued for 2 months. The study design is a randomized double-blinded placebo controlled trial. Once patients have been enrolled, they will undergo baseline investigations. Blood will be drawn from both peripheral and hepatic veins and sent for routine parameters, pro-inflammatory cytokines (IL-1b, IL-6, IL-10, TNF-α, endotoxins, NO2 and NO3 levels, PRA, BNP). Samples will be stored at -70 ºC. Baseline vitals will be recorded. Patients will be called at the end of 1 month for assessment of compliance and then at the end of the study (2 months) to repeat the HVPG and the same parameters as at the time of enrollment End Points: 1. Primary a. Change in HVPG levels as compared with baseline, to define responder (≥20% reduction in HVPG or ≤ 12 mm Hg). 2. Secondary 1. Change in digestive flora 2. Reduction in serum and hepatic endotoxin and cytokine levels 3. Assessment of improvement in the renal parameters and Systemic inflammatory response syndrome 4. Improvement in the markers of oxidative injury 5. Adverse effects
