Melatonin to Prevent Brain Injury in Unborn Growth Restricted Babies - Full Text View

Purpose

Intrauterine growth restriction is the term used to describe a condition where an unborn baby does not reach its optimum size. In the short and long term, intrauterine growth restricted babies have a higher risk of serious disease and even death. It is well established that very low levels of oxygen in the baby's blood can harm the baby's health through a state known as oxidative stress. Currently, there is no established treatment available to treat intrauterine growth restriction or its complications. In experimental animal studies however, the naturally occuring hormone, melatonin, has been shown to significantly reduce oxidative stress and improve health of the unborn babies that have suffered from intrauterine growth restriction. This study aims to find out if the use melatonin twice per day throughout pregnancies affected by intrauterine growth restriction will lower the level of oxidative stress experienced by the unborn baby. If this is the case melatonin may help protect the unborn baby from damage caused by oxidative stress, this will be studied in a separate future study.

Primary Outcome Measures:

Oxidative stress in the umbilical artery [ Time Frame: Once, at birth. ] [ Designated as safety issue: No ]
Umbilical artery oxidative stress by measuring levels of malondialdehyde (MDA) and 8-isoprostane. Levels of MDA will be assessed using a Thiobarbituric Acid Reactive Substances Assay Kit (Cayman Chemical Item Number 10009055). Levels of 8-isoprostane will be assessed using an 8-Isoprostane Enzyme Immuno Assay Kit (Cayman Chemical Item Number 516351).

Secondary Outcome Measures:

Oxidative stress in maternal venous serum [ Time Frame: Once within one week before start treatment and once per week during the treatment period (estimated to be an average of 4 weeks). ] [ Designated as safety issue: No ]
Maternal serum oxidative stress will be assessed by measuring levels of malondialdehyde (MDA) and 8-isoprostane. Levels of MDA will be assessed using a Thiobarbituric Acid Reactive Substances Assay Kit (Cayman Chemical Item Number 10009055). Levels of 8-isoprostane will be assessed using an 8-Isoprostane Enzyme Immuno Assay Kit (Cayman Chemical Item Number 516351).
Fetoplacental Doppler studies [ Time Frame: Once within one week before start treatment and twice per week during the treatment period (estimated to be an average of 4 weeks). ] [ Designated as safety issue: No ]
Fetoplacental Doppler studies (umbilical artery, uterine artery, middle cerebral artery, ductus venosus). Fetoplacental Doppler studies are performed in the clinical assessment of women diagnosed with intrauterine growth restriction by sonography.
Placental oxidative stress [ Time Frame: Once, at birth. ] [ Designated as safety issue: No ]
Placental oxidative stress is assessed by measuring levels of malondialdehyde (MDA) and 8-isoprostane. Levels of MDA will be assessed using a Thiobarbituric Acid Reactive Substances Assay Kit (Cayman Chemical Item Number 10009055). Levels of 8-isoprostane will be assessed using an 8-Isoprostane Enzyme Immuno Assay Kit (Cayman Chemical Item Number 516351)
Gestational age at birth. [ Time Frame: Once, at birth. ] [ Designated as safety issue: No ]
Gestational age at birth will be calculated using the last menstrual period and ultrasound characteristics.
Composite neonatal outcome. [ Time Frame: Participants will be followed for the duration of hospital stay, up to 12 months. ] [ Designated as safety issue: No ]
Composite neonatal outcome (admission to NICU, duration of admission, need and duration of respiratory support, intraventricular haemorrhage, necrotising enterocolitis, abnormal neurological assessment, mortality before discharge). This composite neonatal outcome will be measured by collecting medical record data after clinical assessments.

Study Start Date:	September 2012
Study Completion Date:	November 2014
Primary Completion Date:	October 2014 (Final data collection date for primary outcome measure)

Arms	Assigned Interventions
Experimental: Melatonin Women with IUGR will take 4mg prolonged release melatonin oral tablets twice daily. Treatment will occur as soon as the diagnosis of intrauterine growth restriction is made and the patient has been enrolled to this study until birth. The overall duration of treatment will vary due to the nature of intrauterine growth restriction.	Drug: Melatonin 4mg prolonged release melatonin oral tablets twice daily Other Name: Circadin
