Clinical Trial Summary

Introduction: Intrauterine fetal growth restriction (FGR) is a condition in which the fetus does not realize its growth potential in the uterus. Heavy metals important pollutants produced from anthropogenic activities, has been suggested to be embryotoxic and fetotoxic in a lot of studies. However, the causes of fetal growth restriction are little known and heavy metals merit further investigation. The investigators will be tested whether fetal growth restriction was associated with exposure to these metals/vitamins. Methods: This study was designed to determine maternal plasma/urine/hair, cord plasma, placenta and breast milk tin (Sn), manganese (Mn), Vanadium (V), Magnesium (Mg), cobalt (Co), nickel (Ni), arsenic (As), chromium (Cr), cadmium (Cd), lead (Pb), mercury (Hg), antimony (Sb), aluminium (Al), zinc (Zn), copper (Cu), selenium (Se), iron (Fe), vitamin D, vitamin A, vitamin B12 and folate concentrations in women with FGR (n=55) compared to those of volunteer healthy pregnant women (n=55). These heavy metals concentrations measured using inductively coupled plasma-mass spectrometry were compared.

Description:

This observational case-control study will be conducted at the Department of Obstetrics and Gynecology, Cengiz Gokcek Public Hospital, Gaziantep, Turkey, between May 2020 and February 2021. The protocol was approved by the Ethics Committee for Clinical Research of Gaziantep University (reference no: 2020/131). The study strictly will be adhered to the principles of the Declaration of Helsinki. All subjects will be included in the study gave oral and written informed consent. FGR was defined as an estimated fetal weight (grams) less than the 10th percentile for gestational age. Hadlock I formula were used to calculating estimated fetal weight percentiles. Every woman in the study population will be undergone obstetric ultrasound/doppler examination and fetal-maternal assessment will be carried out. Then, this study will be determined maternal plasma/urine/hair, cord plasma, placenta and breast milk tin (Sn), manganese (Mn), Vanadium (V), Magnesium (Mg), cobalt (Co), nickel (Ni), arsenic (As), chromium (Cr), cadmium (Cd), lead (Pb), mercury (Hg), antimony (Sb), aluminium (Al), zinc (Zn), copper (Cu), selenium (Se), iron (Fe), vitamin D, vitamin A, vitamin B12 and folate concentrations in women with FGR (n=55) compared to those of volunteer healthy pregnant women (n=55).

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	measurements of metals (µg/L) and vitamins concentrations for both groups	The primary outcome in these analyses will measure tin (Sn), manganese (Mn), Vanadium (V), Magnesium (Mg), cobalt (Co), nickel (Ni), arsenic (As), chromium (Cr), cadmium (Cd), lead (Pb), mercury (Hg), antimony (Sb), aluminium (Al), zinc (Zn), copper (Cu), selenium (Se), and iron (Fe) concentrations in FGR group and control group. Moreover, the other primary outcome in these analyses will also measure vitamin D, vitamin A, vitamin B12 and folate concentrations in FGR group and control group.	10 day
Secondary	compare the neonatal outcomes for both groups	The secondary outcome in these analyses will compare composite neonatal outcome (APGAR scores, weight, length, head circumference, abdominal circumference, placental weight and NICU admission) in FGR group and control group.	1 day
