Plain English Summary
Background and study aims
Liver disease is the fifth most common cause of death in the UK and is caused largely by alcohol, viruses and fatty liver disease resulting in liver damage and loss of function. People can survive with large amounts of liver damage but often have severe health complications leading to frequent hospital admissions. In particular, patents have weak immune systems and are highly prone to bacterial infection with over a third developing an infection in hospital. Infection is the major cause of death in these patients and therefore represents a huge challenge to the NHS. Currently infection in liver patients is treated with antibiotics, however the rates of death in these patients have shown little improvement over 20 years. Antibiotics may also cause harmful side-effects (e.g. diarrhoea) and overuse has led to antibiotic resistant bacteria which makes these drugs useless and will be one of medicines’ greatest challenges over the next decade. Albumin is a protein found naturally in blood and is made in the liver. As liver function reduces so does albumin production and blood levels fall. Albumin is safe and currently used in patients with liver failure; however, prescription is varied and although considered beneficial the effects haven’t been tested in clinical trials. Our study aims to see if giving liver patients Human Albumin Solution (HAS) restores their immune response and helps both prevent and improve treatment of infections.
Who can participate?
Aults (aged over 18) admitted to hospital with acute or worsening complications of cirrhosis of the liver.
What does the study involve?
This study includes a feasibility study, to verify whether it is possible to restore albumin levels to near normal. This is followed by a randomised control trial to confirm whether restoring albumin levels improves survival from infection compared to standard treatment. For the feasibility study, all participants are given 20% HAS during their hospital stay up to a maximum of 14 days. The dose given is dependent on how much albumin is found in the participants blood. For the randomized controlled trial, participants are randomly allocated into one of two groups. Those in group 1 are given the immune restorative albumin protocol 20% HAS (dose dependent on blood albumin levels) during their hospital stay up to a maximum of 14 days. Those in group 2 are given standard medical care.
What are the possible benefits and risks of participating?
Not provided at time of registration
Where is the study run from?
The study will take place at up to 44 NHS sites in England, Wales and Scotland.
When is the study starting and how long is it expected to run for?
April 2015 to October 2017
Who is funding the study?
The National Institute for Health Research (NIHR) and the Wellcome Trust (both UK)

| Study hypothesis | 1. Increased circulating concentrations of Cyclooxygenase (COX)-derived eicosanoid prostaglandin E2 (PGE2) drives cirrhosis-associated leukocyte dysfunction and hence the propensity to infection observed in these patients. 2. Infection triggers an acute clinical deterioration with progression of liver failure, development of liver-related complications, organ failure and mortality in patients with cirrhosis. 3. Albumin reduces PGE2 bioavailability and plays a key role in modulating PGE2-mediated immune dysfunction. As it is synthesised in the liver, circulating albumin levels are approximately 50% lower than in patients without advanced liver disease. 4. Therefore in vivo administration of 20% HAS to these patients will improve their leukocyte function thus enhancing their ability to combat infection, reducing the incidence of second/nosocomial infection. This will lead to fewer cases of organ failure and improved mortality. |

| Condition | Liver cirrhosis |
| Intervention | Feasibility Study: In stage 1, a Phase II feasibility study, all patients will receive a daily intravenous infusion of 20% Human Albumin Solution (HAS) during of their admission (maximum of 14 days from randomisation). The dose will be administered to target a daily serum albumin of 35 g/l. T he following suggested protocol will be provided for clinicians: 1. If serum albumin 30-34 g/l give 100 ml 20% HAS 2. If serum albumin 26-29 g/l, give 200 ml 20% HAS 3. If serum albumin 20-25 g/l, give 300 ml 20% HAS 4. If serum albumin <20 g/l, give 400 ml 20% HAS Randomised Control Trial (RCT): In stage 2, a phase III RCT, patients will receive a daily intravenous infusion of either the immune restorative albumin protocol 20% HAS (dose based on the same suggested protocol as the feasibility study) or standard medical care for the duration of their admission (maximum of 14 days from trial randomisation). |
