Androgen precursor Dehydroepiandrosterone Pharmacokinetics in Trauma (ADaPT)

Aim: To find the correct dose to help restore the normal levels of Dehydroepiandrosterone (DHEA) in trauma patients and study the balance between DHEA and Dehydroepiandrosterone Sulphate (DHEAS) just after trauma occurs when the imbalance is at its maximum.
Improvements in the short-term outcomes after severe trauma achieved through early resuscitation may be off set in the medium term by acute inflammatory responses, leading to infection. This excess pro and anti-inflammatory environment in the body impairs the period of rehabilitation that the patient will be undergoing. Research from the SIRS Study (insert link) has shown that a major circulating steroid precursor of sex hormones, Dehydroepiandrosterone (DHEA ) and its stored form DHEAS are low immediately after injury.
Patients who have undergone a trauma will be identified by members of the research team at the SRMRC. After seven days in intensive care, patients will have their usual levels of DHEA and DHEAS measured in the blood. On day eight the patient will be randomly assigned to either receive a DHEA supplement to be placed under their tongue or to be swallowed. If the patient stays in hospital, they will consume the DHEA supplement for two more days to see if it has any beneficial effect upon the cells responsible for the immune response after injury.
This data will then be used to develop and design a much larger randomised controlled trial in trauma patients.
Measure findings: By measuring the levels of DHEA and DHEAS in the blood after supplementation with either a sublingual or oral dose of 50mg.
