About this study

Official title: A Prospective Randomised Controlled Trial of the Effect of Magnesium Sulphate Administration on Red Cell Transketolase Activity in Alcohol Dependent Patients at Risk of Wernicke Korsakoff Syndrome Treated With Thiamine

Patients who suffer Alcohol Use Disorder (AUD) have a 30-80% incidence of thiamine deficiency causing Wernicke's Encephalopathy (WE).

Intravenous (IV) thiamine replacement is standard practice in the treatment of alcoholic patients presenting to the Accident \& Emergency (A\&E) department, however routine co-supplementation with magnesium (administered IV as magnesium sulphate ), which is required as a co-factor for thiamine in some metabolic processes, e. g. on the activity of the enzyme transketolase in red blood cells, is not routine practice in the treatment of these patients. Without correction of concomitant magnesium deficiency there may be impaired utilisation of thiamine resulting in a failure to treat WE.

This study is designed to determine if administration of magnesium to AUD patients affects red cell transketolasae and serum lactate concentrations by itself, or only acts to increase the effect of thiamine on the activity of this enzyme.

Read the detailed description

This is a 3- arm randomised, open label, controlled study in a cohort of alcoholic patients admitted through A\&E. Patients will be randomised to concurrent infusion of one of the following:

  • Arm 1: IV thiamine
  • Arm 2: IV magnesium sulphate followed by delayed IV thiamine
  • Arm 3: IV thiamine and IV magnesium sulphate Thiamine will be administered as IV Pabrinex, a compound preparation which also contains B vitamins and vitamin C. Administration of IV Pabrinex is standard care in this patient group and magnesium sulphate is routinely co-administered at Glasgow Royal Infirmary.
Being tested
Magnesium Sulfate, Pabrinex

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Change in Erythrocyte transketolase activity

    this is a biochemical marker of thiamine activity measured in units per gram of haemoglobin

    Measured: 0 and 2 hours

  2. Change in serum lactate

    Biochemical marker of metabolic dysfunction (expressed as mmol/L)

    Measured: 0 and 2 hours

  3. Change in rate of resolution of alcohol withdrawal syndrome

    time

    Measured: days

Secondary outcomes (4)
  1. lactate dehydrogenase

    biochemical (expressed in mmol/L)

    Measured: 0 and 2 hours

  2. pre and post magnesium

    biochemical (expressed in mmol/L)

    Measured: 0 and 2 hours

  3. pre and post red cell thiamine

    biochemical

    Measured: 0 and 2 hours

  4. establish baseline micronutrient status of patients with alcohol withdrawal syndrome

    biochemical

    Measured: o and 2 hours

Questions about this trial

What is this clinical trial studying?

A Phase 2/3 study testing Magnesium Sulfate and Pabrinex in people with Alcohol Withdrawal and Lactic Acidosis, run by Glasgow Royal Infirmary at 1 site in United Kingdom.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 6 inclusion and 5 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 31 Jul 2019. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United Kingdom. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this combined phase mean?

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Change in Erythrocyte transketolase activity (time frame: 0 and 2 hours). The study lists 3 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT03466528, which also lists 1 linked publication.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 31 Jul 2019.
