About this study

Official title: The Relation Between Acute Changes in the Systemic Inflammatory Response, Thiamine and Magnesium Concentrations and Transketolase Activity After Elective Knee Arthroplasty.

We wish to determine to what extent magnesium, thiamine and transketolase activity are affected by the Systemic Inflammatory Response (SIR). The knee arthroplasty model affords the ideal study design, as surgery generates an inflammatory response.

Blood samples are drawn preoperatively and for up to four days post operatively, and again at three months post-operation.

Read the detailed description

Thiamine and magnesium play a critical role in glucose metabolism and deficiency results in the accumulation of anaerobic metabolites including lactate (1-3).

Thiamine requires magnesium to be converted to its active form, thiamine pyrophosphate (TPP) (4). TPP also requires magnesium to achieve activation of TPP dependent enzymes during metabolism of glucose (5, 6). The 'gold standard' for the measurement of thiamine status is the measurement of Erythrocyte Transketolase Activity (ETKA)(4, 7-9), and this enzyme's activity is dependent on the presence both thiamine pyrophosphate and magnesium (8, 10). ETKA may therefore represent a 'functional marker' of magnesium status (7, 9, 11, 12).

Studies indicate that low plasma thiamine and magnesium are associated with a range of disease processes, many of which are inflammatory (13-17). Other lipid-soluble vitamins and minerals are known to decrease during the systemic inflammatory response (18, 19), however this relationship is not proven for magnesium. The systemic inflammatory response may therefore confound the interpretation of plasma thiamine and magnesium in the context of sepsis, surgery or autoimmune disease. Elective knee arthroplasty, provokes an inflammatory response and therefore provides an excellent controlled model for understanding the body's response to a systemic insult (19).

Obesity is reported to be associated with magnesium deficiency (17, 20). Intracellular magnesium plays a key role in regulating insulin action, insulin-mediated-glucose-uptake and vascular tone (21-23). Several epidemiologic studies have shown that adults and children consuming a western type diet are consuming 30 - 50% of the RDA for magnesium (24, 25). This deficiency appears to be predominantly subclinical and therefore not routinely investigated.

Obesity is also associated with thiamine and magnesium depletion (17, 20, 26, 27). Magnesium deficiency is also associated with a CRP rise (28-30). Thiamine status is proven to affect lactate concentrations in the blood (2, 3). Lactate accumulation is known to precede the onset of insulin resistance and be characteristically found in patients with obesity related diabetes (31-37).

It is therefore possible that an underlying quiescent magnesium and / or thiamine deficiency may mediate insulin resistance. Thiamine, and its more lipid soluble derivative, benfothiamine, have already shown some promise in the treatment of diabetic complications. The therapeutic potential is intriguing, however the relation between acute changes in the systemic inflammatory response and thiamine and magnesium concentrations, require clarification. Failure to prove the reliability of the thiamine and magnesium measurements in the context of the systemic inflammatory response may lead to patients receiving treatment for a measured deficiency of red cell thiamine and serum magnesium concentrations, which is unreliable. If the therapeutic potential of combined treatment with thiamine and magnesium for the optimization of ETKA function is to be realized (8), it is essential that the erythrocyte and plasma values used to determine thiamine status are definitively established in the context of the systemic inflammatory response. The knee arthroplasty model affords the ideal study design for this as there is a strong association between obesity and knee osteoarthritis (38, 39).

Questions about this trial

What is this clinical trial studying?

An observational study of Inflammation and Magnesium Deficiency, 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 1 inclusion and 1 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 28 Apr 2020. 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.

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?

serum magnesium (time frame: three months). 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 NCT03554668, which also lists 6 linked publications.

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 28 Apr 2020.
