Cirrhosis or liver scarring is an important problem in healthcare in the United Kingdom. 60,000 patients are living with this disease and about 11,000 people every year will die because of it. There are several ways in which patients with this severe form of liver disease become unwell or die and bleeding from the oesophagus or stomach is one. Cirrhosis causes pressure changes inside the abdomen and swelling of veins in the oesophagus (called varices) which can bleed catastrophically.~We know that when varices are large we need to treat them with medication called beta-blockers to reduce the pressure in the varices. If the varices are small, we are not sure if we need to treat with beta-blockers and this study aims to address this uncertainty. Patients who are recruited to the study with small varices will be randomised to either beta-blockers or a placebo. We will observe them closely for 3 years for bleeding from their varices or other complications of cirrhosis or side effects of taking medication. This is the amount of time needed to observe for bleeding when the varices are small. We will review the patients every 6 months including assessing the varices by a camera test called an endoscopy at the beginning and each year until the study is finished.~During the study patients will be involved with the conduct and management of the research, and we will feedback to recruited patients the results at the end. We will assess the barriers and facilitators of doctors in primary care - such as General Practitioners - in adjusting the dose of the tablets to optimise treatment effects, and assess patients' views on taking part in the trial, and whether the side effects justify the potential benefits of reducing the risk of bleeding. We estimate this risk could be reduced from 20% of patients having significant bleeding to 10% over 3 years.~We will measure the impact of beta-blockers on the overall costs to the NHS of caring for people with cirrhosis during the trial. We will then assess the impact of treatment on both mortality and quality of life using a combined measure, the Quality Adjusted Life-Year (QALY). We will use a mathematical prediction model to estimate the impact of treatment on costs, mortality and quality of life over a patient's lifetime. We will assess whether any increased costs are justified by better outcomes for patients and represent good value for money for the NHS budget.~Finally, we will publish the results of the study in the medical literature and discuss the findings at medical conferences, patient groups and with charities involved in helping patients with cirrhosis such as the British Liver Trust.
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.
