Comparison of Two Liver Dialysis Systems : MARS Versus SPAD in Severe Liver Failure

France34 participantsStarted 2011-12

Plain-language summary

A critical issue of the clinical syndrome in liver failure is the accumulation of toxins not cleared by the failing liver. Based on this hypothesis, albumin dialysis is used to remove those substances. Albumin dialysis with recirculation (MARS) is the most used system but required specific system and expert environment. Alternative system without recirculation (SPAD) is less expensive and can be realised in critical care services trained to extrarenal epuration. The primary objective of this study is to compare biological and clinical efficacy, pulsatility index of middle cerebral artery modification and tolerance of both systems. This is a prospective, open, cross-over comparative study of two albumin dialysis system. Each patient will receive the two systems in an randomly assessed order. Patients are divided up according to bilirubin plasmatic level. (250µmol/L to 400 µmol/L and \>400µmol/L).

Inclusion Criteria: * severe hepatic failure on acute liver failure or acute on chronic liver failure * hyperbilirubinemia (total plasmatic bilirubin level above 250µmol/L) * hepatic encephalopathy or pruritus or hepatorenal syndrome. * waiting for liver function recovery or liver transplantation * Signed written informed consent by patient or patient's legally appointed representative or reliable person * affiliation to social security Exclusion Criteria: * contraindication to extra-renal epuration * hypersensibility to albumin or excipients * patients for whom 2 albumin dialysis treatment cannot be considered

Questions worth asking your doctor

Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.

1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?

Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.

Questions for the trial coordinator

The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.

1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?

A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.

What they're measuring

Comparison of total plasmatic bilirubin level before and after two albumin dialysis systems : with recirculation (MARS™ system) and without recirculation (SPAD™ system)

Timeframe: Before and at the end of a MARS™ dialysis (8h) and before and at the end of a SPAD™ system dialysis (10h). Participants will be followed for the duration of critical care stay, an expected average of 1 week
